[0055] The application also provides a cleaning method for the underwater sensor data acquisition device with self-cleaning function, which is used for cleaning the underwater sensor data acquisition device with self-cleaning function and includes the following steps:

[0056] S1, hanging water weights on the outer wall of the water storage tank 300 to lower the whole underwater device to the underwater;

[0057] S2, starting the water pump 220 to suck the water in the lifting channel 212, and then lowering the whole sensor with the storage plate 100 to the outside of the cleaning tank 200 to perform underwater monitoring;

[0058] S3, after the predetermined monitoring period arrives, starting the water pump 220 to supply water to the lifting channel 212, and lifting the storage plate 100 until it is attached to the top of the cleaning tank 200, and then discharging the water in the cleaning tank 200 from the drain 230;

[0059] S4, starting the water pump 220 to suck the water in the lifting channel 212 again until the storage plate 100 is lowered to the bottom of the cleaning tank 200, at this time, the negative pressure generated in the cleaning tank 200 causes the water inlet sleeve 313 to be adsorbed and lowered, and then the clean water in the water storage tank 300 flows into the cleaning tank 200 from the center hole of the water inlet sleeve 313 to supplement water;

[0060] S5, then starting the double-head motor 130 to drive the transmission rod 140 to rotate the blade wheel 120, and stirring the clean water in the cleaning tank 200 to form a vortex, and then cleaning and descaling the probe of the sensor;

[0061] S6, starting the water pump 220 to suck the water in the lifting channel 212 again, and then lowering the whole sensor with the storage plate 100 to the outside of the cleaning tank 200 to continue underwater monitoring.

[0062] The present application receives a preset cleaning cycle signal through a PLC controller, and sends an instruction to a driving member, such as a water pump 220 and a double-head motor 130 control circuit, which is a prior art and will not be described herein. The water pump 220 is used to control the water injection amount by running time, thereby indirectly controlling the liquid level and the height of the placement plate. The start and stop of the double-head motor 130 is triggered by the placement plate 100 reaching a specific height. The start and stop of the water pump 220 and the running time of the double-head motor 130 are controlled by a timer inside the PLC.

[0063] Specifically, the present application provides a PLC control water pump 220 and double-head motor 130 working process. The operator sets the target height (H_target) of the placement plate 100. The PLC converts this height into the corresponding liquid level (L_target) of the water storage tank 300.

[0064] For example, the placement plate 100 rises, the PLC starts the water pump 220, and then starts timing the running time of the water pump 220. When the timer reaches the preset time T_up corresponding to the target height (H_target), the PLC stops the water pump 220. At this time, the liquid level reaches L_target, and the height reaches H_target.

[0065] For example, the placement plate 100 needs to be lowered, the PLC starts the water pump 220 to suck the water in the lifting channel 212, the liquid level is lowered, and the placement plate 100 is lowered. The PLC starts timing the drainage time, and when the timer reaches the preset time T_down corresponding to the target lowering height, the PLC stops the water pump 220.

[0066] For example, the start / stop of the double-head motor 130 is strictly related to the position of the placement plate (i.e. the liquid level).

[0067] When the placement plate 100 rises to a certain preset trigger height (H_start) (corresponding to the liquid level L_start), the PLC detects that the position condition is met and starts the double-head motor 130. The double-head motor runs for a preset working time (T_motor_run) to drive the blade wheel 120 to rotate and clean the sensor. After reaching T_motor_run, the PLC stops the double-head motor 130. The double-head motor 130 stops after completing its preset working time, until the next time the placement plate 100 rises to the trigger height.

[0068] It should be noted that the fixed connection, fixed with the terms in the present application are realized by conventional fixing means such as bolt connection or welding. The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and to implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made in accordance with the spirit and essence of the present application should be covered within the protection scope of the present application.
