[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1As shown, a sewage treatment sludge scraping mechanism includes a sewage treatment tank 1. Limiting grooves 3 are formed on the upper surfaces of the left and right parts of the sewage treatment tank 1. Lifting components 2 are movably sleeved inside the two limiting grooves 3. The outer wall of the middle part of the lifting component 2 is movably sleeved with the inner wall of the middle part of the limiting groove 3. A sludge cleaning component 4 is fixedly connected to the lower surface of the lifting component 2. An auxiliary cleaning component 5 is rotatably connected to the upper surfaces of the left and right parts of the sludge cleaning component 4. The outer wall of the upper part of the auxiliary cleaning component 5 is fixedly installed with the inner cavity of the lower part of the lifting component 2.

[0020] First, under the constraint of the two limiting grooves 3, the lifting component 2 and the sludge cleaning component 4 can move back and forth stably on the inner wall of the sewage treatment tank 1. Under the action of the lifting component 2, the height of the sludge cleaning component 4 can be adjusted according to the sludge on the water surface. Then, under the action of the sludge cleaning component 4, the sludge can be cleaned. At the same time, under the action of the auxiliary cleaning component 5, the inner wall of the sewage treatment tank 1 can also be cleaned.

[0021] like Figure 2 As shown, the lifting assembly 2 includes a support frame 21. The outer walls of the left and right parts of the support frame 21 are respectively movably connected to the interior of two limiting grooves 3. A hydraulic cylinder 23 is fixedly connected to the inner cavity of the middle part of the support frame 21. A fixed shell 24 is fixedly connected to the output end of the hydraulic cylinder 23 and the fixed shell 24 is located below the support frame 21. The outer wall of the fixed shell 24 is movably connected to the inner wall of the sewage treatment tank 1. The sludge cleaning assembly 4 includes an inverted T-shaped plate 41. The upper surface of the inverted T-shaped plate 41 is fixedly connected to the lower surface of the fixed shell 24. A sludge filter cover 44 is fixedly connected to the lower surface of the inverted T-shaped plate 41. Fixed frames 42 are fixedly connected to the rear of the left and right parts of the inverted T-shaped plate 41. A three-bladed paddle 43 is fixedly installed on the inner wall of each of the two fixed frames 42. The hydraulic cylinder 23 causes the fixed shell 24 to move the mud filter cover 44 downward, so that the mud is located in the middle of the mud filter cover 44. Then, under the action of the two three-bladed paddles 43, the mud filter cover 44 can move forward, thereby collecting and cleaning the mud on the water surface.

[0022] The inner cavity of the support frame 21 is slidably connected to two guide rods 25, which are located on the left and right sides of the hydraulic cylinder 23. The lower surfaces of the two guide rods 25 are fixedly connected to the upper surface of the fixed shell 24 respectively. The guide rod 25 enables the fixed shell 24 to move stably up and down, thus playing a supporting and guiding role.

[0023] The inner walls of the left and right parts of the support frame 21 are rotatably connected to two movable wheels 22, and the lower surfaces of the outer walls of the four movable wheels 22 respectively overlap with the bottom of the inner walls of the two limiting grooves 3. The movable wheel 22 and the limiting groove 3 enable the device to move more stably under the propulsion of the two three-bladed propellers 43, thereby playing a role in assisting and supporting the movement.

[0024] like Figure 3 As shown, the auxiliary cleaning component 5 includes a motor 51. The left side of the motor 51 is fixedly connected to the inner cavity of the fixed housing 24. A bevel gear set 52 is fixedly connected to the output end of the motor 51. The outer wall of the connecting shaft in the middle of the bevel gear set 52 is rotatably connected to the inner cavity of the fixed housing 24. Bevel gears 53 are meshed on the lower surfaces of the outer walls of the bevel gears on both the left and right sides of the bevel gear set 52. The outer walls of the connecting shafts in the middle of the two bevel gears 53 are rotatably connected to the inner cavity of the fixed housing 24. Bevel gears 54 are meshed on the opposite sides of the outer walls of the lower bevel gears of the two bevel gears 53. Fixed shafts 55 are fixedly connected to the inner walls of the two bevel gears 54. The outer walls of the left and right sides of the two fixed shafts 55 are rotatably connected to the inner walls of the left and right sides of the inverted T-shaped plate 41. Brushes 56 are fixedly connected to the side of the two fixed shafts 55 away from the two bevel gears 53. The opposite sides of the two brushes 56 overlap with the inner walls of the sewage treatment tank 1. The motor 51 enables the bevel gear set 52 to drive the two bevel gears 53 to rotate simultaneously, which in turn enables the two bevel gears 54 to drive the two fixed shafts 55 to rotate. Under the action of the two fixed shafts 55, the two brushes 56 can rotate along the inner wall of the sewage treatment tank 1, thereby cleaning the floating sludge remaining on the inner wall of the sewage treatment tank 1. Since the floating sludge is not firmly attached, it is relatively easy to handle.

[0025] like Figure 4 , Figure 5 As shown, the rear side of the inner wall of the sludge filter cover 44 is V-shaped. A suction pipe 46 is fixedly connected to the upper surface of the rear part of the sludge filter cover 44. A sludge pump 45 is fixedly connected to the upper surface of the suction pipe 46. The front of the sludge pump 45 is fixedly connected to the rear of the middle part of the inverted T-shaped plate 41. A conveying hose 47 is fixedly connected to the upper surface of the sludge pump 45. The floating mud filter cover 44 helps to gather the floating mud. Then, under the action of the sludge pump 45, the suction pipe 46 can extract the floating mud gathered inside the floating mud filter cover 44 and discharge it through the conveying hose 47, thereby efficiently completing the cleaning of the floating mud.

[0026] The working principle of this utility model is as follows: First, the height of the sludge filter cover 44 can be adjusted according to the height of the sludge by the action of the hydraulic cylinder 23. Then, the device can move forward along the inner wall of the two limiting grooves 3 under the action of the four moving wheels 22. At this time, the sludge can be gathered by the action of the sludge filter cover 44. Then, under the action of the sludge pump 45, the suction pipe 46 can be used to extract the sludge gathered inside the sludge filter cover 44 and discharge it through the conveying hose 47. At the same time, the motor 51 can drive the bevel gear set 52 to rotate the two bevel gears 53, so that the two bevel gears 54 can drive the two fixed shafts 55 to rotate. Under the action of the two fixed shafts 55, the two brushes 56 can rotate along the inner wall of the sewage treatment tank 1, thereby cleaning the sludge remaining on the inner wall of the sewage treatment tank 1.
