[0043] The other end of the impact assembly passes through the multi-stage filtering mechanism and is inserted into the water inlet hole on the water cylinder 1;

[0044] When the power assembly is in motion, the impact assembly performs linear motion in the water inlet hole.

[0045] Among them, the main invention point of the present application is that by setting up a power component, the impact component can be driven to clear the water inlet, so that the power component can be started regularly to avoid hard objects getting stuck at the water inlet, resulting in water being unable to enter the water barrel, or the water flow rate entering the water barrel being unstable. The accuracy of the results of the water pumping test can be improved.

[0051] The motor 3 is connected to the top of the substrate, and a sealed cavity is arranged outside the motor 3 .

[0052] Among them, the motor is connected to an external computer, and the motor can be started by the computer, thereby driving the screw rod to rotate, and then driving the turntable to move linearly on the screw rod, and then driving the impact component to impact the water inlet hole, thereby knocking down the hard object stuck in the water inlet hole.

[0053] The water pumping assembly includes: a water pump 12 and a water pipe 13 connected to the water outlet end of the water pump 12;

[0054] The water pump is connected to the top of the base plate, and the water pipe passes through the top of the water cylinder and extends to the ground.
