When the water volume is insufficient and the water in the auxiliary water supply tank 2 needs to be pumped out, the cleaner water in the middle is also preferentially pumped out from the bottom end of the liquid pipe 6, and the bottom accumulated liquid with sediment is regularly discharged from the drain valve 4, which solves the problem that the existing device may still discharge water with sediment when discharging liquid.

[0026] Embodiment 2:

[0030] Two groups of auxiliary pipes 7 are fixedly connected to both sides of the liquid pipe 6 and communicated therewith, and the auxiliary pipes 7 are oblique pipes.

[0031] The working principle and use process of the utility model are as follows: when the device is needed to work, the sediment inside the water body will fall, and the sediment falling on the top surface of the blocking seat 10 will automatically slide into the auxiliary water supply tank 2 and accumulate in the sedimentation tank 21.

When the water level is insufficient, the first solenoid valve 8 is closed and the second solenoid valve 9 is opened to pump out cleaner water from the middle of the auxiliary water supply tank 2 upwards. Finally, when all the water is placed inside the auxiliary water supply tank 2, the drain valve 4 is opened regularly to discharge the bottom accumulated liquid with sediment, so as to achieve the cleaning effect.
