[0066] The working principle of the use method of the present application is as follows:

[0067] When the working mechanism 1 is used for sewage treatment, sewage is first discharged into the sedimentation tank body 11 through the water inlet pipe 14, and then moves from left to right in the sedimentation tank body 11, in the process, the sewage passes through the perforations of the flow regulation mechanism 2 for flow regulation, and the suspended solids in the sewage continuously settle in the sludge hopper of the sedimentation tank body 11 under the action of gravity, and finally the treated sewage is discharged through the water outlet pipe 15, when the suspended solids stored in one sludge hopper are too much, the two push pumps 61 are started to make the two push plates 62 move horizontally in opposite directions, thereby driving the rotating assembly 4 to rotate, and then driving the fixed assembly 5 to deflect downward, so that the two fixed assemblies 5 are in the shape of an included angle and contact with the wall surface of the connecting block 12, that is, the top of the sludge hopper to be cleaned is closed, at this time the sewage discharge pipe 13 in the sludge hopper can be started to suck and clean the suspended solids in the sludge hopper, it should be noted that since the first movable part 3a and the second movable part 3b are alternately arranged, and the states of the first movable part 3a and the second movable part 3b are opposite, the top of the sludge hopper adjacent to the sludge hopper is open, therefore, the cooperation of the two fixed assemblies 5 and the two connecting blocks 12 not only effectively prevents the suspended solids from scattering everywhere during the cleaning of the sludge hopper, improves the sewage treatment effect, but also effectively drives the suspended solids to settle in the adjacent sludge hopper, improves the sewage treatment efficiency.

[0068] When the sludge hopper needs to be opened to receive suspended solids, the two push pumps 61 are started to make the two push plates 62 push the rotating assembly 4 to rotate in the opposite direction, thereby driving the fixed assembly 5 to deflect upward, so that the two fixed assemblies 5 are in a vertical state and fit the wall surface of the flow regulation mechanism 2, that is, the top of the sludge hopper is opened, which can fully collect the settled suspended solids, in the process of keeping the fixed assembly 5 in a vertical state, the fixed assembly 5 will block part of the perforations on the flow regulation mechanism 2, so that the moving speed of the sewage is reduced, the residence time of the sewage above the sludge hopper is prolonged, the suspended solids are fully settled in the sludge hopper, and the sewage treatment effect is improved.

[0069] In the process of rotating the rotating assembly 4, the tooth block 43 is engaged with the vertical tooth groove of the flow regulation plate 22, so that the rotating assembly 4 drives the flow regulation plate 22 to move up and down in the flow regulation piece 21, thereby fully cleaning the perforations on the flow regulation mechanism 2, preventing the perforations from being blocked, enhancing the ability of the flow regulation mechanism 2 to continuously regulate, effectively reducing the turbulence of the sewage when moving, and reducing the influence on the settlement of the suspended solids, at the same time, due to the deflection of the fixed assembly 5, the moving part 54 will move on the fixed plate 51, thereby cleaning one side wall surface of the fixed plate 51, and the moving part 54 will also extrude the fixed capsule 53, so that the fixed capsule 53 deforms and vibrates continuously, thereby cleaning the other side wall surface of the fixed plate 51, and thus cleaning the suspended solids on the fixed assembly 5, preventing affecting the timely cleaning of the suspended solids in the sedimentation tank body 11.
