[0002] The present disclosure relates to a technical field of a water landscape device, and in particular, to water pumps for an urban water landscape.

[0003] A water pump is a mechanical device that pressurizes water or other liquids and transports the water or other liquids to a high place. Most of the current water pumps lack an anti-fouling device, so in the application of a water landscape such as a private garden or an urban park, sticky substances such as fish feces or algae are very likely to exist on the blades of the water pump, thereby affecting the working efficiency of the water pump, even causing damage to the water pump, and reducing the service life of the water pump. In addition, as the water pump is usually installed somewhere at the bottom of the water landscape, it is inconvenient to disassemble components of the water pump and an operation such as replacement, cleaning, etc. is cumbersome and time-consuming.

[0034] In order to more clearly illustrate the technical solutions related to the embodiments of the present disclosure, a brief introduction of the drawings referred to the description of the embodiments is provided below. Obviously, the drawings described below are only some examples or embodiments of the present disclosure. Those having ordinary skills in the art, without further creative efforts, may apply the present disclosure to other similar scenarios according to these drawings. Unless obviously obtained from the context or the context illustrates otherwise, the same numeral in the drawings refers to the same structure or operation.

[0035] It should be understood that the “system,” “device,” “unit,” and/or “module” used herein are one method to distinguish different components, elements, parts, sections, or assemblies of different levels. However, if other words can achieve the same purpose, the words can be replaced by other expressions.

[0036] As used in the disclosure and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the content clearly dictates otherwise; the plural forms may be intended to include singular forms as well. In general, the terms “comprise,” “comprises,” and/or “comprising,” “include,” “includes,” and/or “including,” merely prompt to include steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive listing. The methods or devices may also include other steps or elements.

[0037] The flowcharts used in the present disclosure illustrate operations that the system implements according to the embodiment of the present disclosure. It should be understood that the foregoing or following operations may not necessarily be performed exactly in order. Instead, the operations may be processed in reverse order or simultaneously. Besides, one or more other operations may be added to these processes, or one or more operations may be removed from these processes.

[0038] A water pump may be a mechanical device that pressurizes water or other liquids and transports them to a high place. Before the water pump is turned on, the water pump may need to be immersed in water to fill the water pump with liquid. After the water pump is turned on, a motor may drive a water pump impeller to rotate at a high speed and liquid may fly away from the impeller under the action of a centrifugal force. When a liquid pressure gradually increases, the liquid may be discharged from a liquid outlet of the water pump and enter a pipe or above a water surface.

[0039] At present, most water pumps for a water landscape may lack an anti-fouling device or only have a simple filter screen. In the water landscape, sticky substances such as fish feces or algae may be very easy to exist on the blades of the water pump, which may affect the working efficiency of the water pump, even cause damage to the water pump, and reduce the service life of the water pump. In addition, as the water pump is usually installed somewhere at the bottom of the water landscape, even if the anti-fouling device or a filtering device is installed, the anti-fouling device or the filtering device may be usually fixedly installed with a water pump main body as an integrated structure, which is difficult to be disassembled. If the anti-fouling device or the filtering device needs to be replaced or cleaned, operations may be cumbersome and time-consuming. If the anti-fouling device or the filtering device is not replaced and cleaned for a long time, the filtration efficiency may be reduced, resulting in poor water quality.

[0040] In view of this, some embodiments of the present disclosure provide water pumps for an urban water landscape, which can enable the water pump to have an effective filtering function and facilitate replacement or maintenance of the filtering device.

The filter component annular frame 301 may be used to support and install various components of the filter component 3. The filter hole plate 302 may be used to cooperate with the filter component annular frame 301 to limit a filling position of the filter medium 303. The filter component handle 305 may be used to lift the filter component for easy replacement.

[0056] In some embodiments, as shown in FIG. 4, the two filter hole plates 302 may be detachably covered on front and back openings of the filter component annular frame 301, respectively. Outer edges of the two filter hole plates 302 may be provided with the sealing rings 304. The sealing rings 304 may be widened and thickened.

Other substances with a size of smaller than 0.5 cm may pass through a first filter component 3 configured with a filter medium such as a coarse filter cotton, a gauze element, etc., and impurity particles may be trapped in the first filter component 3. Impurities that have not been adsorbed and filtered by the first filter component 3 may enter a second filter components 3 configured with a filter medium such as a volcanic stone, a breathing ring, etc. and may be absorbed and filtered by the second filter component 3. The pool water passed through the two filter components 3 may enter the water channel 7 inside the water pump main body from the water inlet hole 6 of the water pump main body and drive the impeller 10 to rotate with the motor 9. The filtered pool water may be pumped out from the water outlet interface 5 on the top of the water pump body through the water channel 7. The water outlet flow of the water pump main body may be controlled by adjusting the flow control valve 20 on the water outlet interface 5. When the filtered impurities in the filter component 3 accumulate to a certain extent, the old filter component 3 may be pulled out from the filter component slot 15 and may be replaced with a new filter component 3 or the filter medium in the filter component 3 may be replaced and the initial filtration efficiency of the filter component 3 may be achieved without taking out the water pump main body from the pool. The buckles may be adopted between the filter component 3 and the filter component slot 15 and between the filter component annular frame 301 and the filter hole plate 302, which can facilitate the replacement of the filter component 3 on the filter component slot 15 and the replacement of the filter medium 303 inside the filter component 3.

In some embodiments, the water pump may include an inductive alarm device, such as an infrared alarm device. The closer the new filter component 3 is detected to the water pump, the louder the prompt sound may be, thereby assisting in determining whether the filter component 3 is installed in place. In some embodiments, the computing platform may control the extension of the telescopic rod 311 until the telescopic rod 311 extends out of the water based on a warning sent by the inductive alarm device that senses the new filter component 3. The connection ring 310 of the new filter component 3 may be placed on the telescopic rod 311. Under the action of a gravity and a magnet attraction, the new filter component 3 may enter the corresponding position of the water pump and then the telescopic rod 311 may be retracted.

[0074] A water quality detection sensor refers to a sensor used to detect a water quality condition. For example, the water quality detection sensor may be a residual chlorine sensor, a conductivity sensor, a Pondus Hydrogenii (pH) sensor, an oxidation-reduction potential (ORP) sensor, a turbidity sensor, etc.

[0075] The pressure sensor may be used to detect a pressure of the water filtered by the filter component. For example, the pressure sensor may be a resistance strain gauge pressure sensor, a semiconductor strain gauge pressure sensor, a piezoresistive pressure sensor, etc. In some embodiments, the pressure sensor may be disposed on the second filter component 3.

[0076] In some embodiments, the pressure sensor may communicate with the computing platform according to a preset communication time.

[0077] The pressure sensor may be configured to communicate periodically with the computing platform. The preset communication time refers to a time when the pressure sensor communicates with the computing platform periodically. For example, the preset communication time may be 12 hours, that is, the pressure sensor may communicate with the computing platform once every 12 hours, the suspension ball 309 may be released during the communication, and the suspension ball 309 may be retracted when the communication ends.

[0078] In some embodiments, the computing platform may include a processor. The processor may be used to determine, based on a received pressure sensor reading, a time to replace the filter component 3. The processor may be further used to re-determine, based on the time to replace the filter component 3, the preset communication time.

[0079] In some embodiments, the processor may be used to determine to replace the filter component 3 in response to a determination that the received pressure sensor reading is greater than or equal to a threshold.

[0080] In some embodiments, the threshold refers to a pressure threshold preset manually based on experience or by the processor based on historical data. When the pressure of the water filtered by the filter component 3 is greater than or equal to the pressure threshold, it may mean that a filtration performance of the filter component 3 cannot meet the requirement and the filter component 3 needs to be replaced. In some embodiments, the threshold may be adjusted based on a detected amount of impurities through performing an impurity detection on the replaced filter component 3. In some embodiments, the threshold may be adjusted according to a preset corresponding relationship and the preset corresponding relationship may be obtained manually based on the experience or experiments, for example, the relationship between the amount of impurities and the pressure may be obtained through the experiments.

[0081] In some embodiments, the processor may predetermine the time to replace the filter component 3 by predicting pressure at a future moment, so as to prepare for the replacement in advance and improve the working efficiency of the water pump. In some embodiments, the processor may predict the pressure at the future moment based on a pressure prediction model and determine the time to replace the filter component based on the pressure at the future moment.

[0082] FIG. 9 is a model diagram illustrating a pressure prediction model according to some embodiments of the present disclosure.

[0083] As shown in FIG. 9, in some embodiments, the pressure prediction model 900 may include a pressure feature embedding layer 930, a water quality feature embedding layer 940, and a pressure prediction layer 970. An input of the pressure feature embedding layer 930 may include pressure sensor readings 910 at a plurality of moments in a current or previous preset period of time and an output of the pressure feature embedding layer 930 may include a pressure feature embedding vector 950. An input of the water quality feature embedding layer 940 may include water quality features 920 at the plurality of moments in the current or previous preset period of time and an output of the water quality feature embedding layer 940 may include a water quality feature embedding vector 960. An input of the pressure prediction layer 970 may include the pressure feature embedding vector 950, the water quality feature embedding vector 960, and a filter medium feature 980 and an output of the pressure prediction layer 970 may include pressure 990 at the one or more future moments. The pressure sensor readings 910 at the plurality of moments in the current or previous preset period of time may be obtained by the pressure sensor. The water quality features 920 at the plurality of moments in the current or previous preset period of time may be obtained by a water quality detection sensor. The filter medium feature 980 may include a feature of the filter medium 303, such as a type, a mass, a density, etc. of the material.

[0084] In some embodiments, when the pressure at the one or more future moments output by the pressure prediction model 900 is greater than or equal to a threshold, the one or more future moments may be taken as the times to replace the filter component.

[0085] In some embodiments, the output of the pressure feature embedding layer 930 and the output of the water quality feature embedding layer 940 may be the input of the pressure prediction layer 970. The pressure feature embedding layer 930, the water quality feature embedding layer 940 and the pressure prediction layer 970 may be obtained through joint training. In some embodiments, sample data of the joint training may include pressure sensor readings at a plurality of moments in a sample preset period of time, water quality features at the plurality of moments in the sample preset period of time, and a sample filter medium feature in historical detection data. A label may be sample pressure at the one or more future moments determined manually based on actual detection data. The pressure sensor readings at the plurality of moments in the sample preset period of time and the water quality features at the plurality of moments in the sample preset period of time may be respectively input to the pressure feature embedding layer and the water quality feature embedding layer to obtain the pressure feature embedding vector and the water quality feature embedding vector respectively output by the pressure feature embedding layer and the water quality feature embedding layer. The pressure feature embedding vector and the water quality feature embedding vector output respectively by the pressure feature embedding layer and the water quality feature embedding layer may be used as sample training data. The sample training data and the sample filter medium feature may be input into the pressure prediction layer to obtain the pressure at the one or more future moments output by the pressure prediction layer. A loss function may be constructed based on the sample pressure at the one or more future moments determined manually according to the actual detection data and the pressure at the one or more future moments output by the pressure prediction layer. Parameters of the pressure feature embedding layer, the water quality feature embedding layer, and the pressure prediction layer may be updated synchronously until a preset condition is satisfied and the training may be completed. The preset condition may be the loss function being smaller than a threshold, converging, or the training period reaching a threshold, or the like, or any combination thereof.

[0086] In some embodiments, the input of the pressure prediction layer may further include a water exchange rate of the water pump and a correlation between the pressure sensor reading and the water exchange rate of the water pump.

[0087] The water exchange rate of the water pump refers to a rate at which the water pump filters the water. For example, the water exchange rate of the water pump may be 10 m/s.

[0088] In some embodiments, the pressure sensor reading may have a negative correlation with the water exchange rate of the water pump, that is, the greater the pressure sensor reading is, the smaller the water exchange rate of the water pump may be. The reason may be that the greater the pressure sensor reading is, the more impurities the current filter component 3 adsorbs and the lower the adsorption capacity is. The water exchange rate of the water pump may need to be reduced, so that the time for water to pass through the filter component may increase to avoid the reduction of the filtering effect.

[0089] In some embodiments, the re-determining, based on the time to replace the filter component 3, the preset communication time may include: determining a new preset communication time based on a preset correspondence between the time to replace the filter component 3 and the preset communication time. The time to replace the filter component 3 may be proportional to the preset communication time to the preset communication time.

[0090] For example, if the time to replace the filter component 3 is relatively long, the preset communication time may be increased accordingly. Exemplarily, the original preset communication time may be 12 hours. In actual use, it may be found that the filter component 3 is replaced every 5 days, so there is no need to communicate frequently. The preset communication time may be re-determined as 48 hours or more than 48 hours.

[0091] In some embodiments, the processor may be further used to determine the water exchange rate of the water pump based on the pressure sensor reading. In some embodiments, the water exchange rate of the water pump may be adjusted by adjusting the flow control valve 20. In some embodiments, the greater the pressure sensor reading is, the more impurities the current filter component 3 adsorbs, and the lower the adsorption capacity is, the smaller the water exchange rate of the water pump may be required to achieve the filtering effect. In some embodiments, the water exchange rate of the water pump may be reduced by reducing the water flow through the flow control valve 20.
