DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer toFigures 1-4 , a sedimentation tank for water treatment in a water conservancy project, including a tank body 1. The bottom wall of the tank body 1 is an annular inclined plane 2. A silt collection tank 3 is arranged at the center of the inclined plane 2. The silt accumulated at the bottom of the tank body 1 is collected from the inclined plane 2 into the silt collection tank 3

[0023] A vertical rod 5 is inserted into the center of the silt collection tank 3. The bottom of the silt collection tank 3 is communicated with a drainage tank 4 arranged at the bottom of the tank body 1. A sludge scraping plate 7 is rotatably connected to the vertical rod 5. The sludge scraping plate 7 is driven by a rotation module 8. The sludge scraping plate 7 accelerates the sludge on the inclined plane 2 into the silt collection tank 3. The specific principle is as follows:

[0024] The sludge scraping plate 7 includes a plate body 71. A collar 73 is arranged at the end of the plate body 71. The collar 73 is rotatably sleeved on the vertical rod 5. An inclined side 72 is arranged on the side wall of the plate body 71. When the plate body 71 and the inclined side 72 rotate, the force on the sludge is F as Figure 2 shown. There is an angle C between the force F and the velocity V, which will cause the sludge to move downward along the inclined plane 2 under the action of the sludge scraping plate 7 and finally fall into the silt collection tank 3

[0025] The top of the vertical rod 5 is connected with a lifting module 10. The bottom of the vertical rod 5 is fixedly connected with a plug 6 for separating the drainage tank 4 and the silt collection tank 3. When the silt in the tank body 1 is cleared, the water in the tank body 1 is pumped out. The lifting module 10 drives the vertical rod 5 to rise, and the plug 6 rises. The silt collection tank 3 and the drainage tank 4 are communicated, and the silt enters the drainage tank 4 from the silt collection tank 3 and is discharged

[0026] Specifically, the lifting module 10 includes a plurality of brackets 101. One end of the brackets 101 is fixedly supported by a support plate 102. An electric cylinder 103 is fixedly connected to the bottom of the support plate 102. The telescopic end of the electric cylinder 103 is fixedly connected with a mounting plate 9. A plurality of guide rods 104 are arranged at the bottom of the support plate 102. The guide rods 104 slidably penetrate through the mounting plate 9. The electric cylinder 103 controls the lifting of the vertical rod 5

[0027] The rotation module 8 includes a motor 81. The top of the motor 81 is fixed to the mounting plate 9. A driving gear 82 is fixed to the driving end of the motor 81. The driving gear 82 meshes with a driven gear ring 84. The inner ring of the driven gear ring 84 is welded with a bearing 83. The bearing 83 is sleeved on the vertical rod 5. A connecting rod 85 is welded to the side wall of the bearing 83. The bottom of the connecting rod 85 is fixed to the plate body 71. The motor 81 drives the connecting rod 85 to rotate around the vertical rod 5 through the driving gear 82 and the driven gear ring 84, and the connecting rod 85 drives the sludge scraping plate 7 to rotate on the inclined plane 2
