Therefore, they cannot be understood as limitations on the present invention.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figure 1-Figure 5 As shown, a sewage treatment sedimentation tank includes a sedimentation tank body, which includes a tank shell 101. The inner wall of the tank shell 101 is fixedly connected to uniformly arranged guide rods 106. A cleaning mechanism is provided on the tank shell 101. The cleaning mechanism includes a winch assembly 301 fixedly connected to the top of the tank shell 101. The winch assembly 301 is rotatably connected to a rope shaft. The rope shaft on the winch assembly 301 is wound with a traction rope 302. One end of the traction rope 302 is fixedly connected to a support block 303. The support block 303 is slidably connected to the guide rod 106. A cleaning plate 304 is detachably connected between the two support blocks 303. One side of the cleaning plate 304 contacts the inner wall of the tank shell 101. A mud discharge mechanism is provided at the lower end of the tank shell 101. The mud discharge mechanism is used to remove the mud from the bottom of the tank shell 101. The deposited sludge is discharged from the pool shell 101. A power mechanism is provided on the rear side of the pool shell 101. The power mechanism is used to make the cleaning mechanism and the mud discharge mechanism move. A counterweight block is fixedly connected to the cleaning plate 304. A brush is fixedly connected to the side of the cleaning plate 304 close to the inner wall of the pool shell 101. The winch assembly 301 rotates, driving the traction rope 302 to continuously wrap around the rope shaft of the winch assembly 301. This process drives the support block 303 to move upward along the guide rod 106. The upward movement of the support block 303 drives the cleaning plate 304 to move upward. When the cleaning plate 304 moves downward, the winch assembly 301 rotates in the opposite direction, and the cleaning plate 304 moves downward under the action of gravity. The movement of the cleaning plate 304 can scrape the adsorbed matter on the inner wall of the pool shell 101 to the bottom of the sedimentation tank.

[0026] The support block 303 is internally connected to a symmetrically arranged sliding wheel 305, which clamps the guide rod 106 in the middle. The sliding wheel 305 rotates continuously during the movement of the cleaning plate 304, which can make the movement of the cleaning plate 304 on the guide rod 106 smoother.

[0027] An inlet pipe 102 is fixedly connected to the rear side of the pool shell 101, an outlet pipe 103 is fixedly connected to the front side of the pool shell 101, a sludge bucket 104 is fixedly connected to the bottom of the pool shell 101, and a gate 105 is fixedly connected to the sludge bucket 104. Sewage enters the pool shell 101 from the inlet pipe 102, and the sewage settles in the pool shell 101. After sedimentation, the pollutant content of the upper layer of water is small, and the upper layer of water leaves the sedimentation tank from the outlet pipe 103. The sludge discharge mechanism pushes the settled sludge to the front of the sedimentation tank, and the staff opens the gate 105 to discharge the sludge from the sludge bucket 104 to the sedimentation tank.

[0028] The power mechanism includes a motor 201 fixedly connected to the pool housing 101, and the output end of the motor 201 is fixedly connected to a driving wheel 202. A first driven wheel 203 is symmetrically provided on the upper side of the driving wheel 202, and the first driven wheel 203 is connected to the driving wheel 202 through a chain transmission. The first driven wheel 203 is rotatably connected to the rear side of the pool housing 101, and a second driven wheel 205 is provided on the lower side of the driving wheel 202. The driving wheel 202 and the second driven wheel 205 are connected through a chain transmission, and the second driven wheel 205 is rotatably connected to the rear side of the pool housing 101. A transmission shaft 204 is fixedly connected to the first driven wheel 203, and the transmission shaft 204 is fixedly connected to the rope winding shaft on the winch assembly 301. The rotation of the motor 201 drives the driving wheel 202, and the rotation of the driving wheel 202 drives the first driven wheel 203 to rotate through the chain transmission. The rotation of the first driven wheel 203 drives the winch assembly 301 to rotate, and the rotation of the driving wheel 202 drives the second driven wheel 205 to rotate.

[0029] The sludge discharge mechanism includes a rotating shaft 401 rotatably connected to the pool shell 101, and a spiral blade 402 is fixedly connected to the rotating shaft 401. The pitch of the spiral blade 402 gradually decreases from back to front. The second driven wheel 205 rotates to drive the rotating shaft 401 to rotate, and the rotation of the rotating shaft 401 drives the spiral blade 402 to rotate. The continuously shrinking pitch of the spiral blade 402 can push the sludge to the front end and squeeze it.

[0030] Working principle: sewage enters the pool shell 101 from the water inlet pipe 102, and the sewage is precipitated in the pool shell 101. After precipitation, the pollutant content of the upper layer of water is small, and the upper layer of water leaves the sedimentation tank from the outlet pipe 103. The motor 201 rotates to drive the driving wheel 202, and the driving wheel 202 rotates to drive the first driven wheel 203 to rotate through the chain transmission. The rotation of the first driven wheel 203 drives the winch assembly 301 to rotate. The winch assembly 301 rotates, driving the traction rope 302 to continuously wind around the rope shaft of the winch assembly 301. This process drives the support block 303 to move upward along the guide rod 106. The upward movement of the support block 303 drives the cleaning plate 304 to move upward, and the cleaning plate 304 moves upward. During downward movement, the winch assembly 301 rotates in the opposite direction, and the cleaning plate 304 moves downward under the action of gravity. The movement of the cleaning plate 304 can scrape the adsorbed matter on the inner wall of the pool shell 101 to the bottom of the sedimentation tank. The driving wheel 202 rotates to drive the second driven wheel 205 to rotate, and the rotation of the second driven wheel 205 drives the rotating shaft 401 to rotate. The rotation of the rotating shaft 401 drives the spiral blade 402 to rotate. The spiral blade 402 continuously reduces the pitch, which can push the sludge to the front end and squeeze it. The mud discharge mechanism pushes the settled sludge to the front of the sedimentation tank. The staff opens the gate 105 to discharge the sludge from the mud discharge bucket 104 to the sedimentation tank, thus completing the cleaning work of the sedimentation tank.
