In some embodiments, an inner side edge of the filter hole plate 302 may be provided with a plurality of filter hole plate blocks. Front and back edges of the filter component annular frame 301 may be provided with filter hole plate block slots 307 matching the filter hole plate blocks. The filter hole plate 302 may be fixedly connected to the filter component annular frame 301 through clamping and fitting between the filter hole plate blocks and the filter hole plate block slots 307.

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.

The telescopic rod 311 may be disposed on the water pump shell 4 and the grille net cover 2 adjacent to the filter component 3. The telescopic rod 311 may be retractable. The filter component 3 may be disposed with a connection ring 310. The connection ring 310 may correspond to a position of the telescopic rod 311. The telescopic rod 311 may be used to guide a new filter component 3 into the water pump when the filter component is replaced. The magnet may be disposed on the filter component pallet 13.

The cable 308 may be used to extract the filter component 3 from the water and for communication. The cable 308 may include a wire core, an insulating layer, a shielding layer, a protective layer, etc. For example, the cable may be an insulated polyvinyl chloride cable, a tinned or silver-plated cable, a water-cooled cable, etc.

The suspension ball 309 may be a device capable of emerging from the water. In some embodiments, the suspension ball 309 may be a hollow sphere. For example, the suspension ball 309 may be a hollow sphere made of polyurethane-polyethylene compound, polystyrene-wrapped cloth, or crusted polyethylene. In some embodiments, the suspension ball 309 may have an eye-catching color, such as a paint with a bright color, a fluorescent paint, etc. When the filter component 3 needs to be replaced, the cable 308 may be easily found through the suspension ball 309, so that the filter component 3 may be drawn out by pulling the cable. The suspension ball 309 may be released and retracted periodically and the power for the retraction may be provided by the water pump. For example, the reel of the cable 308 may be disconnectably connected to the motor 9 through the transmission mechanism (e.g., the transmission mechanism may be a device for power transmission including a mechanism such as a gear, etc. and control whether to disconnect by controlling engage and disengage of the gears in the transmission mechanism) and a controller may control the connection and disconnection between the reel of the cabal 308 and the motor 9 to realize the periodical release and retraction of the suspension ball 309.

The computing platform may be used to receive and process data and send an instruction, etc. In some embodiments, the computing platform may be disposed in a control room on shore.

The telescopic rod 311 refers to a device for guiding the filter component 3 into the water pump. In some embodiments, the telescopic rod 311 may be retractable. The filter component 3 may be provided with the connection ring 310. The connection ring 310 may correspond to the position of the telescopic rod 311. In some embodiments, the telescopic rod 311 may include a rod body and a connection buckle. The connection buckle may be disposed on an upper part of the rod body for fastening with the connection ring 310 on the filter component 3.

The filter component 3 and the water pump may be further installed in place through an action of a magnetic force. 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.

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

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.

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.

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.

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.

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.

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.
