[0059] In the embodiment, since the motor 601 is arranged on the driving seat 6 in a staggered manner and the rotating piece 603 is arranged between the two partition bins 4 in a layered manner, the corresponding motor 601 can drive the sprocket on the output end to rotate when the motor 601 is reversed, so that the motor 601 can drive the rotating drum of the rotating piece 603 to rotate in the limiting seat 602 through the chain transmission assembly 604, and at this time, the rotating drum can drive the rotating disc at one end to rotate.

[0060] Please refer to Figure 4 、 Figure 6 and Figure 7 , the surface of the rotating disc of the rotating piece 603 is symmetrically provided with a driving groove 6031 for reciprocating the push-pull lever 507.

[0061] In the embodiment, when the rotating drum drives the rotating disc to rotate in the positive direction or the reverse direction, the driving groove 6031 on the surface of the rotating disc can reciprocate the lever 507 on the rack bar 506, so that the rotating disc of the rotating piece 603 can drive the rack bar 506 to mesh with the toothed track 503 on the sealing plug 501 to drive, and then the sealing plug 501 can control the water inlet channel to be sealed or opened.

The filter plates a705 and b706 are longitudinally misaligned and slide on the front surface of the mounting seat 703. The filter plates a705 and b706 expanded by misaligned sliding can block and filter the upper and lower gaps between the two fixed seats 504. The filter plates a705 and b706 are both arc-shaped structures. The central part of the filter plate a705 is longitudinally provided with a sawtooth cavity 7051, and the central part of the filter plate b706 is longitudinally provided with a sawtooth groove 7061 corresponding to the position of the sawtooth cavity 7051.

[0070] In the embodiment, when the sealing plug 501 rotates away from the water inlet channel in the radial direction, the rotating sealing plug 501 can drive the fixed disc 702 to drive the multi-rib output shaft protruding from the cover 7022 to rotate, so that the multi-rib output shaft can drive the hollow tooth column 704 to rotate in the mounting seat 703. The rotating hollow tooth column 704 is misaligned and engaged with the sawtooth cavity 7051 in the central part of the filter plate a705 and the sawtooth groove 7061 in the central part of the filter plate b706, respectively. Therefore, the rotating hollow tooth column 704 can drive the filter plates a705 and b706 to misalign and slide along the mounting seat 703, ensuring that the filter plates a705 and b706 are misaligned and expanded along the arc trajectory on the front surface of the mounting seat 703.

[0071] The misaligned and expanded filter plates a705 and b706 arcuately block the upper and lower gaps between the two fixed seats 504, and the filter plates a705 and b706 can be used to filter clean water into the gap between the water inlet channel and the sealing plug 501, preventing floating debris such as branches, leaves, plastic bags, and foam in the sedimentation tank 1 from blocking the gap between the water inlet channel and the sealing plug 501. Since the gap structure between the water inlet channel and the sealing plug 501 is designed in a ring shape, it can be used for circular drainage during drainage, effectively preventing humans or animals falling into the sedimentation tank 1 from entering the drain pipe 2. The misaligned and expanded filter plates a705 and b706 can also keep the blocked debris in the sedimentation tank 1.

[0072] Conversely, when the hollow toothed column 704 rotates reversely and reversely dislocates with the sawtooth cavity 7051 and the sawtooth groove 7061 respectively, the hollow toothed column 704 can drive the filter plate a 705 and the filter plate b 706 to longitudinally dislocate and contract on the front surface of the mounting seat 703, so as to ensure that the filter plate a 705 and the filter plate b 706 are stacked and stored on the front surface of the mounting seat 703.

[0073] The rack rod 506, the filter plate a 705, the filter plate b 706 and the connecting rod 8 on the two partition compartments 4 are distributed in an up-down dislocation manner, and the rack rod 506, the filter plate a 705, the filter plate b 706 and the connecting rod 8 are distributed in an up-down dislocation manner on the outer side of the two partition compartments 4. The two dislocated rack rods 506 can be driven by the rotating member 603 to drive two groups of sealing plugs 501 in the same layer to be opened synchronously, and the two groups of dislocated filter plate a 705 and filter plate b 706 can be driven to be unfolded.

[0074] Working principle: all the motors 601 are started from top to bottom to drive the rotating member 603 arranged in layers to rotate forward and reversely in a cycle, so that the rotating member 603 in dislocation can drive the sealing plug 501 arranged in layers to be opened and closed;

[0075] When the water level in the sedimentation tank 1 reaches a sufficient height and submerges the uppermost sealing plug 501, the rack rod 506 of the drainage mechanism 5 opens the uppermost sealing plug 501 on one side of the partition compartment 4, so that the clear water in the upper layer can enter from the upper and lower gaps between the two fixed seats 504 and enter the partition compartment 4 along the gap between the water inlet channel and the sealing plug 501. When the valve 201 on the drainage pipe 2 is opened, the clear water in the partition compartment 4 will enter the water collecting tank 3 along the drainage pipe 2;

[0076] When the water level in the sedimentation tank 1 reaches the middle layer of the sealing plug 501, the middle layer of the drainage mechanism 5 opens the middle layer of the sealing plug 501, so that the clear water in the middle layer can enter the water collecting tank 3 from the partition compartment 4 and the drainage pipe 2. Similarly, when the water level in the sedimentation tank 1 reaches the lower layer of the sealing plug 501, the lower layer of the drainage mechanism 5 opens the lower layer of the sealing plug 501, so that the clear water in the lower layer can enter the water collecting tank 3 from the partition compartment 4 and the drainage pipe 2, ensuring that the clear water in the sedimentation tank 1 can enter the partition compartment 4 in layers, and ensuring that the clear water in each layer entering the partition compartment 4 can flow smoothly, which can prevent all the clear water in the sedimentation tank 1 from flowing rapidly along the lowermost water inlet channel and causing the sediment to flow;

[0077] It needs to be emphasized that the water level inside the sedimentation tank 1 is from high to low to start the layered drainage mechanism 5, so that the upper layer of clean water can first enter the catchment tank 3 along the partition bin 4 and the drain pipe 2, and the lower layer of clean water can enter the catchment tank 3 along the partition bin 4 and the drain pipe 2, ensuring that the rainwater in the sedimentation tank 1 can be discharged layer by layer after completing the sedimentation of the sediment;

[0078] It also needs to be pointed out that when the drainage mechanism 5 of a certain layer is opened, the sealing plug 501 of other layers will not be opened, and only when the sealing plug 501 of the upper layer completes the closure to block the water inlet channel, the sealing plug 501 of the next layer can be opened through the drainage mechanism 5, and the contents not described in detail in this description belong to the existing technology known to those skilled in the art.
