[0007] Furthermore, side plates are fixedly connected to both ends of the top side of the base at positions above the corresponding slide plates. A bidirectional screw is rotatably connected between the side plates. The two ends of the bidirectional screw are threadedly connected to the corresponding fixed plates. A first limiting rod is fixedly connected between the side plates. The fixed plates are slidably connected to the first limiting rod. A drive motor is fixedly connected to the outer side of one of the side plates at the position corresponding to the bidirectional screw. The output end of the drive motor passes through the corresponding side plate and is fixedly connected to one end of the bidirectional screw.

[0008] Furthermore, a second limiting rod is fixedly connected to the upper side of the skateboard near the corresponding movable frame, the top of the movable frame is slidably connected to the corresponding second limiting rod, a throttle is fixedly connected to the top of the one-way screw, and a limiting block is fixedly connected to the top of the second limiting rod.

[0013] The beneficial effects of this utility model are:

[0014] When in use, this sedimentation tank sludge scraping device has the following advantages:

[0015] 1. In this solution, a chute, sliding plate, fixed plate, side plate, bidirectional screw, first limit rod, movable frame, side scraper, unidirectional screw, throttle, and second limit rod are installed. The drive motor rotates the bidirectional screw, which in turn moves the fixed plate, sliding plate, and movable frame at both ends in opposite directions or towards each other until the side scrapers on both sides abut against the side wall of the sedimentation tank. This allows for adjustment of the spacing between the side scrapers according to the width between the side walls of the sedimentation tank. During the movement of the base, the sludge adhering to the side walls of the sedimentation tank is scraped off simultaneously, improving scraping efficiency. Rotating the throttle rotates the corresponding unidirectional screw, which in turn moves the corresponding movable frame. The movable frame can be raised and lowered to adjust the height of the movable frame and side scraper, facilitating sludge scraping at different heights on the side wall of the sedimentation tank. Equipped with telescopic rods, springs, a top plate, crossbars, connecting rods, and cleaning scrapers, pressing down on the top plate compresses the corresponding telescopic rods and springs, causing the crossbars and connecting rods to move downwards. The cleaning scraper then moves downwards to remove the accumulated sludge from the side scraper surface. Releasing the top plate resets the telescopic rods and springs, allowing the cleaning scraper to return to its original position at the top of the side scraper for easy cleaning next time. Cleaning the side scraper is quick and convenient, preventing sludge buildup on the surface and ensuring effective sludge removal.

[0016] 2. In this scheme, a connecting plate, suction box, horizontal scraper, suction pipe, recovery box, sludge pump, conveying pipe, sewage pipe, casters, and push handle are installed. During the forward movement, the horizontal scraper scrapes off the sludge attached to the bottom surface of the sedimentation tank and the sludge that falls off when scraping the side walls. The sludge pump is started, and the sludge-liquid mixture scraped off the bottom surface is pumped into the suction box through the suction pipe, and then pumped into the recovery box through the conveying pipe. The control valve of the sewage pipe is opened, and the sludge pumped into the recovery box can be discharged through the sewage pipe. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-5As shown, a sludge scraping device for a sedimentation tank is disclosed, comprising a base 1, a chute 2 on the top side of the base 1, and sliding plates 3 slidably connected to both ends of the chute 2. One end of each sliding plate 3 extends to the outside of the base 1, and a fixing plate 4 is fixedly connected to the opposite side of each sliding plate 3. A movable frame 12 is provided on the outside of each sliding plate 3, and the movable frame 12 has an inverted L-shaped structure. Several side scrapers 13 are vertically fixedly connected to the outside of each movable frame 12. A one-way screw 9 is rotatably connected to the upper side of each sliding plate 3 near the corresponding movable frame 12. One end of each is threadedly connected to the corresponding movable frame 12. The top of each movable frame 12 is fixedly connected to a telescopic rod 14. The top of each telescopic rod 14 is fixedly connected to a top plate 16. A spring 15 is sleeved on the outside of each telescopic rod 14. The two ends of the spring 15 are fixedly connected to the corresponding movable frame 12 and the top plate 16 respectively. One end of each top plate 16 is fixedly connected to a crossbar 17. The bottom side of the crossbar 17 is fixedly connected to a connecting rod 18 at the position in front of the corresponding side scraper 13. The bottom of each connecting rod 18 is fixedly connected to a cleaning scraper 19.

[0027] like Figure 1-5 As shown, side plates 5 are fixedly connected to both ends of the top side of the base 1 above the corresponding slide plates 3. A bidirectional screw 6 is rotatably connected between the side plates 5. The two ends of the bidirectional screw 6 are threaded to the corresponding fixed plates 4. A first limiting rod 8 is fixedly connected between the side plates 5. The fixed plates 4 are slidably connected to the first limiting rod 8. A drive motor 7 is fixedly connected to the outer side of one of the side plates 5 at the position corresponding to the bidirectional screw 6. The output end of the drive motor 7 passes through the corresponding side plate 5 and is fixedly connected to one end of the bidirectional screw 6. When the drive motor 7 is started, the bidirectional screw 6 is rotated, which causes the fixed plates 4 at both ends to move in opposite directions or towards each other along the first limiting rod 8. This causes the slide plates 3 on both sides to move in opposite directions or towards each other along the slide groove 2. This causes the movable frames 12 on both sides to move in opposite directions or towards each other as a whole until the side scrapers 13 on both sides abut against the side wall of the sedimentation tank, so that the spacing of the side scrapers 13 on both sides can be adjusted according to the width between the side walls of the sedimentation tank.

[0028] like Figure 1-5 As shown, a second limiting rod 11 is fixedly connected to the upper side of the slide plate 3 near the corresponding movable frame 12. The top of the movable frame 12 is slidably connected to the corresponding second limiting rod 11. A handle 10 is fixedly connected to the top of the one-way screw 9. A limiting block is fixedly connected to the top of the second limiting rod 11. Rotating the handle 10 will drive the corresponding one-way screw 9 to rotate, thereby driving the corresponding movable frame 12 to move up and down along the corresponding second limiting rod 11 to adjust the height of the movable frame 12 and the side scraper 13, which is convenient for scraping sludge at different heights on the side wall of the sedimentation tank.

[0029] like Figure 1-5As shown, one end of each cleaning scraper 19 is in contact with the front side of the corresponding side scraper 13, and the other end of the cleaning scraper 19 located between the two side scrapers 13 is in contact with the rear side of the other side scraper 13. Initially, the telescopic rods 14 are all in the extended state, and the cleaning scrapers 19 are all located above the side scrapers 13. Pressing down on the top plate 16 compresses the corresponding telescopic rods 14 and springs 15, thereby driving the crossbars 17 and connecting rods 18 to move downward. Then, the cleaning scrapers 19 are used to scrape away the sludge accumulated on the surface of the side scrapers 13. After releasing the top plate 16, the springs 15 return to their original position, causing the telescopic rods 14 to extend, and the cleaning scrapers 19 return to their original position and move back to the top of the side scrapers 13 for easy cleaning next time.

[0030] like Figure 1-5 As shown, a connecting plate 20 is fixedly connected to the front side of the base 1, and a suction box 21 is fixedly connected to the front side of the connecting plate 20. A horizontal scraper 22 is fixedly connected to the rear bottom of the suction box 21, with the lower end of the horizontal scraper 22 contacting the ground. During forward movement, the horizontal scraper 22 scrapes away the sludge adhering to the bottom surface of the sedimentation tank and the sludge falling off the sidewalls. Several suction pipes 23 are installed through the bottom of the suction box 21, located in front of the horizontal scraper 22. A recovery box 24 is fixedly connected to the center of the bottom of the base 1, and a sludge pump 2 is fixedly connected to the rear side of the recovery box 24. 5. The input end of the sludge pump 25 is fixedly connected to the conveying pipe 26. One end of the conveying pipe 26 passes through and connects to the inside of the suction box 21. The output end of the sludge pump 25 passes through and connects to the inside of the recovery box 24. When the sludge pump 25 is started, the sludge mixture liquid material scraped off the bottom surface is drawn into the suction box 21 through the suction pipe 23, and then drawn into the recovery box 24 through the conveying pipe 26. The bottom of the recovery box 24 has a bucket-shaped structure. A sewage pipe 27 is installed through the bottom of the recovery box 24. A control valve is installed at one end of the sewage pipe 27 to facilitate the discharge of sludge.

[0031] like Figure 1-5 As shown, casters 28 are fixedly connected to the four corners of the bottom of the base 1, and a push handle 29 is fixedly connected to the rear of the base 1, making it easy to move to any position.

[0032] Working principle: During use, the drive motor 7 is started, which drives the bidirectional screw 6 to rotate, thereby causing the fixed plates 4 at both ends to move in opposite directions or towards each other along the first limit rod 8. This, in turn, causes the sliding plates 3 on both sides to move in opposite directions or towards each other along the slide groove 2. Consequently, the movable frames 12 on both sides move in opposite directions or towards each other until the side scrapers 13 on both sides abut against the side wall of the sedimentation tank. This allows for adjustment of the spacing of the side scrapers 13 according to the width between the side walls of the sedimentation tank. During the movement, the sludge attached to the side walls of the sedimentation tank is scraped off simultaneously, improving efficiency. Turning the handle 10 drives the corresponding unidirectional screw 9 to rotate, thereby causing the corresponding movable frame 12 to move up and down along the corresponding second limit rod 11. This adjusts the height of the movable frame 12 and the side scrapers 13, facilitating sludge scraping at different heights on the side walls of the sedimentation tank. 13. When scraping sludge, sludge easily accumulates on the surface, affecting the scraping effect. At this time, press down on the top plate 16, thereby compressing the corresponding telescopic rod 14 and spring 15, which in turn drives the crossbar 17 and connecting rod 18 to move downward. Then, the cleaning scraper 19 moves downward to scrape off the sludge accumulated on the surface of the side scraper 13. Release the top plate 16, and the telescopic rod 14 and spring 15 will return to their original extension. The cleaning scraper 19 will return to its original position and move back to the top of the side scraper 13 for easy cleaning next time. During the forward movement, the horizontal scraper 22 scrapes off the sludge attached to the bottom of the sedimentation tank and the sludge that falls off when scraping the side wall. Start the sludge pump 25. The sludge mixed with liquid scraped off the bottom surface is drawn into the suction box 21 through the suction pipe 23, and then drawn into the recovery box 24 through the delivery pipe 26. Open the control valve of the sewage pipe 27, and the sludge drawn into the recovery box 24 can be discharged through the sewage pipe 27.
