DETAILED DESCRIPTION

[0026] In order to make the technical scheme of the present invention better understood by the personnel of the technical field, the technical scheme in the embodiment of the present invention is clearly and completely described below.

The tank body 1 is a rectangular parallelepiped with a hollow interior. The slow-flow mechanism 2 is arranged at the top of the tank body 1. A water inlet pipe 11 is fixedly provided on the side wall of the tank body 1 at one end along its length direction above the slow-flow mechanism 2, and the water inlet pipe 11 is connected to the interior of the tank body 1. A water outlet pipe 12 is also fixedly provided on the side wall of the tank body 1 at the other end along its length direction above the slow-flow mechanism 2, and the water outlet pipe 12 is connected to the interior of the tank body 1. A groove (not shown in the figure) is provided on the side wall of the tank body 1 along its width direction, and a transparent plate 13 is fixedly provided at the groove for observing the progress of sewage sedimentation. The first cleaning mechanism 3 is used to clean the slow-flow mechanism 2, and the second cleaning mechanism 4 is used to clean the bottom of the tank body 1.

[0028] When in use, pour sewage into the pool body 1 from the water inlet pipe 11, and the sewage will move downward along the slow flow mechanism 2 to settle. During the sedimentation process, the sedimentation progress can be observed from the transparent plate 13. As the sewage in the pool body 1 gradually increases, the settled water will gradually rise to the outlet pipe 12 and flow out. After using it for a period of time, a lot of mud and sand will remain on the slow flow mechanism 2. Starting the first cleaning mechanism 3 can clean the slow flow mechanism 2, and starting the second cleaning mechanism 4 can clean the bottom of the pool body 1, which saves time and effort, helps to increase the cleaning rate, and improves the sewage treatment efficiency.

[0029] Reference Figure 2 and Figure 3 , and refer to Figure 4 , the slow flow mechanism 2 includes an inclined plate 21, a first rotating rod 22, a connecting plate 23, a second rotating rod 24, a connecting rod 25, and a first cylinder 26. The number of inclined plates 21 is multiple, and in this embodiment, there are five. The five inclined plates 21 are evenly spaced along the length direction of the pool body 1, and the distance between two inclined plates 21 is the width of the inclined plate 21, which can enable the inclined plate 21 to rotate to a horizontal state. The number of first rotating rods 22 is multiple, and in this embodiment, there are five, and the five first rotating rods 22 correspond to the five inclined plates 21 one by one. The first rotating rod 22 is arranged along the width direction of the pool body 1, and the first rotating rod 22 passes through the long axis position of the inclined plate 21, and the two ends are respectively fixed on the side wall of the pool body 1, and the inclined plate 21 is rotatably connected to the first rotating rod 22. The number of connecting plates 23 and second rotating rods 24 is multiple, and in this embodiment, there are five, and they correspond to the five inclined plates 21 one by one. The connecting plate 23 is arranged at an end corner of the side wall of the pool body 1 near the top of the inclined plate 21. One end of the second rotating rod 24 is hinged at one end of the connecting plate 23 along its length direction, and the other end passes through the top of the inclined plate 21, and the inclined plate 21 is fixedly connected to the second rotating rod 24. The other end of the connecting plate 23 is fixed to the pool body 1 through the first hinge rod 27, and the connecting plate 23 is hinged to the first hinge rod 27. The connecting rod 25 is arranged along the length direction of the pool body 1, and the connecting rod 25 is arranged at five connecting plates 23. The length of the connecting rod 25 is the sum of the distances between the five connecting plates 23, and the connecting rod 25 is hinged to each first hinge rod 27. The first cylinder 26 is arranged in the pool body 1 above the connecting rod 25, and the first cylinder 26 is arranged along the height direction of the pool body 1. The top end of the first cylinder 26 is fixed to the pool body 1 via the second hinged rod 28 , the first cylinder 26 is hinged to the second hinged rod 28 , and the bottom end of the first cylinder 26 is hinged to the connecting rod 25 .

[0030] Two adjacent connecting plates 23, two adjacent inclined plates 21 and the connecting rod 25 therebetween form a part of a parallelogram. Since the connecting plates 23 and the connecting rod 25 are in a hinged state, pushing the connecting rod 25 can cause the connecting plates 23 to rotate.

[0031] After using it for a period of time, when the inclined plate 21 needs to be cleaned, the first cylinder 26 is started. The first cylinder 26 is extended or shortened to push the connecting rod 25. The connecting rod 25 can drive the connecting plate 23 to rotate around the first hinge rod 27 to a vertical state, thereby driving the inclined plate 21 to rotate around the first rotating rod 22 to a horizontal state, and then starting the first cleaning mechanism 3 to clean the inclined plate 21. After cleaning, start the first cylinder 26 again to make the inclined plate 21 inclined, and the mud and sand will fall from the inclined plate 21 to the bottom of the pool body 1, and start the second cleaning mechanism 4 to clean the bottom of the pool body 1, thereby realizing the cleaning of the pool body 1.

[0032] Reference Figure 2 and Figure 5 The first cleaning mechanism 3 is arranged above the inclined plate 21. The first cleaning mechanism 3 includes a screw 31, a slider 32, a limit rod 33, a first driving assembly 34, a lifting assembly 35, a second driving assembly 36, and a cleaning assembly 37. Figure 1 and Figure 6 , a chute 15 adapted to the slider 32 is provided at one end of the inner top wall of the pool body 1 along its width direction, and the chute 15 is arranged along the length direction of the pool body 1. The screw rod 31 is arranged in the chute 15, and one end of the screw rod 31 is rotatably connected to the side wall of the pool body 1, and the other end passes through the side wall of the pool body 1 and is rotatably connected thereto. The slider 32 is sleeved on the screw rod 31 and is rotatably connected thereto. The limit rod 33 is arranged parallel to the screw rod 31 and is also arranged in the chute 15. The limit rod 33 passes through the slider 32, and both ends are fixed on the side wall of the pool body 1, and the limit rod 33 is slidably connected to the slider 32. The first driving assembly 34 includes a motor 341, which is fixed on the outer wall of the pool body 1 near the end of the screw rod 31 passing through the pool body 1, and the output shaft of the motor 341 is fixedly connected to the end of the screw rod 31 passing through the pool body 1. The lifting assembly 35 includes a second cylinder 351, and the second cylinder 351 is arranged along the height direction of the pool body 1. The second cylinder 351 is disposed below the slider 32, the top of the second cylinder 351 is fixedly connected to the bottom of the slider 32, the other end of the second cylinder 351 is fixedly provided with an inverted L-shaped plate 38, and the cleaning assembly 37 is disposed on the inverted L-shaped plate 38. The second driving assembly 36 is used to drive the cleaning assembly 37 to rotate.

[0033] Reference Figure 2 and Figure 7The second driving assembly 36 includes a rack 361, a circular gear 362, a first bevel gear 363, and a second bevel gear 364. The rack 361 is arranged along the length direction of the pool body 1 and is fixed on the side wall of the pool body 1 above the inclined plate 21. The circular gear 362 is arranged below the inverted L-shaped plate 38, and the circular gear 362 can mesh with the rack 361. A first fixed rod 365 is arranged between the circular gear 362 and the inverted L-shaped plate 38, and the top end of the first fixed rod 365 is fixed on the inverted L-shaped plate 38, and the bottom end is rotatably connected to the circular gear 362. The first bevel gear 363 is fixed below the circular gear 362, and the second bevel gear 364 is arranged on the side wall of the inverted L-shaped plate 38 near the cleaning assembly 37, and the first bevel gear 363 is meshed with the second bevel gear 364.

[0034] Reference Figure 2 and Figure 7 The cleaning assembly 37 includes a brush rod 371 and bristles 372. The brush rod 371 is arranged along the width direction of the pool body 1, and the length of the brush rod 371 is greater than the length of the inclined plate 21. A second fixing rod 373 is fixedly arranged at one end of the brush rod 371 close to the inverted L-shaped plate 38, and an end of the second fixing rod 373 away from the brush rod 371 passes through the inverted L-shaped plate 38 and is fixedly connected to the second bevel gear 364, and the second fixing rod 373 is rotatably connected to the inverted L-shaped plate 38. The bristles 372 are arranged in a spiral shape and fixedly arranged on the brush rod 371.

[0035] After the inclined plate 21 is adjusted to the horizontal rotation state, the second cylinder 351 is started to drive the inverted L-shaped plate 38 to move, so that the circular gear 362 is meshed with the rack 361, and then the motor 341 is started. The motor 341 can drive the screw rod 31 to rotate. Due to the threaded connection between the slider 32 and the screw rod 31 and the limiting effect of the limiting rod 33, the slider 32 can only move along the length direction of the screw rod 31, so that the circular gear 362 moves along the rack 361, and the circular gear 362 rotates, which can also drive the first bevel gear 363 to rotate. , because the first bevel gear 363 and the second bevel gear 364 are meshed, the second bevel gear 364 is driven to rotate, so that the brush rod 371 is rotated, and the bristles 372 clean the inclined plate 21. As the slider 32 moves, the bristles 372 will sweep the mud and sand on the inclined plate 21 to one end of the pool body 1 along its length direction, and then the first cylinder 26 is started to tilt the inclined plate 21, so that the mud and sand on the inclined plate 21 can be poured to the bottom of the pool body 1, and then the second cleaning mechanism 4 is started to clean the bottom of the pool body 1. When the inclined plate 21 is not cleaned, the second cylinder 351 is started, and the second cylinder 351 drives the cleaning component 37 and the second drive component 36 to move upward to the top of the water inlet pipe 11, which can reduce the rust of the cleaning component 37 and the second drive component 36 caused by sewage entering the pool body 1, which is conducive to extending the service life.

[0036] Reference Figure 2 and Figure 3The side wall of the pool body 1 is hinged with a baffle 14 at the bottom position below the water inlet pipe 11. The baffle 14 is fixed to the pool body 1 by screws at one end along its length direction, and a sealing ring (not shown in the figure) is fixed along the circumference of the side wall of the baffle 14 close to the slow flow mechanism 2. Figure 8 The second cleaning mechanism 4 includes a third cylinder 41 and a scraper 42. The third cylinder 41 is arranged along the length direction of the pool body 1, and one end is fixedly arranged on the side wall of the bottom of the pool body 1 away from the baffle 14, and the other end is fixedly connected to the scraper 42. The scraper 42 is arranged along the width direction of the pool body 1 and is arranged perpendicular to the bottom surface of the pool body 1. The bottom end of the scraper 42 abuts against the bottom surface of the pool body 1.

[0037] Open the screw and start the third cylinder 41. The third cylinder 41 can push the scraper 42 to move, so that the scraper 42 clears the mud and sand on the bottom of the pool body 1 until it is pushed out from the baffle 14, thereby completing the cleaning of the bottom of the pool body 1.

[0038] The operating principle of the present application is as follows: sewage enters the tank body 1 from the water inlet pipe 11, and will flow to the bottom of the tank body 1 through the inclined plate 21 for sedimentation. The sedimentation progress can be observed from the transparent plate 13. As the sewage in the tank body 1 gradually increases, the sediment will remain in the tank body 1, and the settled sewage will rise to the outlet pipe 12 for discharge. After a period of use, the first cleaning mechanism 3 is started to clean the inclined plate 21, and the second cleaning mechanism 4 is started to clean the bottom of the tank body 1, which can improve the cleaning efficiency of the sedimentation tank and help improve the sewage treatment efficiency.
