Detailed Description

The present embodiment is described in detail below with reference to the accompanying drawings.

As shown in figures 1 and 2, the cleaning system for the storage tank comprises a tank wall, a tank bottom 1 and a sewage gallery 2, the cleaning system comprises a water pump 3, a rotating motor 4, a bent pipe 5, an air inlet pipe 6, a Venturi tube 7, an ultrasonic liquid level meter 8, a PLC (programmable logic controller) 9 and an upper computer 10, the water pump 3 is fixed at the tank bottom 1, a water inlet pipe of the water pump 3 extends into the sewage gallery 2, a water outlet pipe is connected with the bent pipe 5, a water outlet of the bent pipe 5, a gas outlet of the air inlet pipe 6 and a water inlet of the Venturi tube 7 are connected through a tee 11, the air inlet pipe 6 extends out of the water surface of the storage tank all the time, the rotating motor 4 is fixedly connected with the tank bottom 1 through a supporting seat 12, an output shaft 17 of the rotating motor 3 is connected with the bent pipe 5 and used for driving the bent pipe 5 and the Venturi tube 7 to, The rotating motor 4, the ultrasonic liquid level meter 8 and the regulating valve 13 are in signal connection with the PLC 9, and the PLC 9 is in signal connection with the upper computer 10.

In the embodiment, the device also comprises a camera monitoring device 14, and the camera monitoring device 14 is fixed on the pool wall and is in signal connection with the PLC 9.
