DETAILED DESCRIPTION

[0020] The following is only a preferred embodiment of the present invention, and the protection scope is not limited to this embodiment. All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. At the same time, it should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

[0021] As shown in the figure, a sewage treatment sedimentation tank diversion device includes a sedimentation tank 1. A sealing groove 12 is provided on the outside of the sedimentation tank 1, a sealing ring 15 is fixedly connected to the bottom of the sealing cover 2, and a sealing liquid is provided in the sealing groove 12. The cross section of the sealing cover 2 is in the shape of a "human", and the diversion groove 3 is vertical. A guide block 16 is fixedly connected to the top of the sealing cover 2, and a connecting groove is provided on the surface of the guide block 16. The sealing cover 2 is located above the sedimentation tank 1, and the sealing ring 15 enters into the sealing liquid to perform liquid sealing on the sedimentation tank 1 during the sedimentation process.

[0022] A sealing cover 2 is provided on the top of the sedimentation tank 1, and a flow guiding structure is provided inside the sealing cover 2. The flow guiding structure includes a flow guiding groove 3, a positioning rod 4, a torsion spring 5, a connecting ring 6, a rotating ring 7 and a rotating plate 8. The flow guiding groove 3 is opened on the top of the sealing cover 2, the connecting ring 6 is connected to the inner side of the flow guiding groove 3, the positioning rod 4 passes through the connecting ring 6, the positioning rod 4 passes through the torsion spring 5, the top of the rotating plate 8 is connected to the rotating ring 7, and the positioning rod 4 passes through the rotating ring 7. A flow guiding pipe 11 is fixedly connected below the sealing cover 2, and the cross section of the flow guiding groove 3 is located inside the flow guiding pipe 11. The liquid inlet pipe is inserted into the flow guiding groove 3, driving the rotating plate 8 to rotate downward, and the torsion spring 5 drives the rotating rod 10 to rotate. After the water inlet is completed, it is reset and restored to a sealed state.

[0023] Regarding the sealing of the guide groove 3 by the rotating plate 8, two rotating plates 8 can be used for sealing, or a rotating plate 8 with an area larger than the guide groove 3 can be used for sealing.

[0024] The torsion spring 5 includes a torsion spring body, a fixed rod 9 and a rotating rod 10. The fixed rod 9 and the rotating rod 10 are respectively connected to the two ends of the torsion spring body. When the torsion spring 5 is in a normal state, the fixed rod 9 is parallel to the rotating rod 10, the top of the fixed rod 9 is in contact with the sealing cover 2, and one end of the rotating rod 10 is in contact with the bottom of the rotating plate 8.

[0025] Working principle: The sealing cover 2 is located above the sedimentation tank 1, and the sealing ring 15 enters the sealing liquid to seal the sedimentation tank 1 during the sedimentation process. The liquid inlet pipe is inserted into the guide groove 3, driving the rotating plate 8 to rotate downward, and the torsion spring 5 drives the rotating rod 10 to rotate. After the water is filled, it is reset and restored to the sealed state.

[0026] In summary, the rotating plate 8 is driven to rotate by the torsion spring 5 to control the sealing inside the sedimentation tank 1 during water inflow and sedimentation, thereby preventing debris from entering the sedimentation tank 1 during sedimentation.
