[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0023] Reference Figure 1-4, this embodiment provides a scraping type gravity self-cleaning manhole cover device, which includes a sundry room 3 and a power room 5 opened below the road surface. The sundry room 3 is arranged close to the road shoulder 9. The upper part of the power room 5 is connected to the road shoulder 9 through a water inlet pipe 11. The inlet end of the water inlet pipe 11 is flush with the road surface. A power part is arranged in the power room 5. The power part is correspondingly arranged below the outlet end of the water inlet pipe 11. A travel switch part is arranged at the outlet end of the water inlet pipe 11. The power part is drivingly connected with two tooth plates 8. The same scraper 7 is fixedly connected to the side of the two tooth plates 8 away from the power part. The scraper 7 and the two tooth plates 8 form a "C" shaped structure. The tooth plates 8 penetrate through the road shoulder 9, and the scraper 7 is in contact with the top surface of the manhole grate 6.
[0024] The sundries carried in the sewage will block the manhole grate 6, thereby causing sewage accumulation. When the sewage accumulates to a certain extent, it will flow from the water inlet pipe 11 at the road shoulder 9 into the power room 5 and enter the power part. The power part converts the potential energy of the water body into mechanical energy, and drives the two tooth plates 8 to extend and retract from the road shoulder 9, reciprocatingly scraping the blockage and restoring the drainage function of the manhole grate 6. The present invention uses the gravitational potential energy of the sewage as the energy source to drive the operation of the whole device, without the input of external energy, energy-saving and environment-friendly, and can effectively remove the blockage above the manhole grate 6.
[0025] In a further optimized solution, the power part includes a second rotating shaft 15. The second rotating shaft 15 is drivingly connected with the tooth plate 8. The two ends of the second rotating shaft 15 are rotatably connected to the opposite side walls of the power room 5. A first towing rope 18 is wound around the middle part of the second rotating shaft 15. One end of the first towing rope 18 away from the second rotating shaft 15 is fixedly connected with a water container 21. The water container 21 is vertically movably arranged in the power room 5. The middle part of the first towing rope 18 bypasses the towing rope guiding part. An inlet net (not shown in the figure) is arranged on the top surface of the water container 21, and a water leakage hole 33 is opened on the bottom surface of the water container 21. The water body enters the water container 21 through the inlet net and is discharged to the outside of the water container 21 from the water leakage hole 33. The water inflow is much larger than the water drainage. The weight of the water container 21 increases rapidly and moves downward, thereby driving the second rotating shaft 15 to rotate through the first towing rope 18. The second rotating shaft 15 drives the tooth plate 8 to move. After the water container 21 moves to the lower limit position, the outlet end of the water inlet pipe 11 is blocked through the travel switch part, so that the sewage no longer flows into the water container 21.
[0026] In a further optimized design, a second gear 14 is coaxially fixed to the middle of the second rotating shaft 15. A first rotating shaft 12 is rotatably connected to the side wall of the power chamber 5. The first rotating shaft 12 is parallel to the second rotating shaft 15. A first gear 13 is coaxially fixed to the middle of the first rotating shaft 12, and the first gear 13 meshes with the second gear 14. Two driven gears 31 are coaxially fixed to both ends of the first rotating shaft 12, and the driven gears 31 mesh with the gear plate 8. Rebound parts are provided at both ends of the first rotating shaft 12 or the second rotating shaft 15. The rotation of the second rotating shaft 15 drives the second gear 14 to rotate. The second gear 14 drives the first rotating shaft 12 to rotate through meshing with the first gear 13. The first rotating shaft 12 drives the gear plate 8 to move linearly through the driven gears 31. Straight teeth are fixed to the bottom of the gear plate 8, and the straight teeth mesh with the driven gears 31. During the fall of the water container 21, the rebound parts store elastic potential energy.
[0027] The design is further optimized by including two coil springs 30 symmetrically arranged. One end of each coil spring 30 is fixedly connected to the side wall of either the first rotating shaft 12 or the second rotating shaft 15, and the other end is fixedly connected to the side wall of the power chamber 5. When the sewage in the water container 21 is emptied, the coil springs 30 release their elastic potential energy, causing the first rotating shaft 12 to reverse, thereby retracting the toothed plate 8 and the scraper 7. The toothed plate 8 carries the blockage towards the debris chamber 3, causing the blockage to fall into the debris chamber 3. During the reversal of the first rotating shaft 12, the water container 21 moves upward again, triggering the limit switch through the edge of the water container 21. The limit switch reopens the outlet end of the inlet pipe 11, repeating the process of sewage entering the water container 21.
[0028] In a further optimized design, several first slide rails 19 are fixedly connected to the bottom of the power chamber 5. The first slide rails 19 are vertically arranged and slidably connected to the side wall of the water container 21. The first slide rails 19 can limit the sway of the water container 21, allowing the water container 21 to move in a vertical straight line.
[0029] Further optimization of the design: The limit switch includes a pin 25, which is fixedly connected to the side wall of the power chamber 5. The pin 25 is rotatably connected to the middle of a rotating rod 24. A plug 23 is fixedly attached to the top of one end of the rotating rod 24, and the plug 23 is positioned opposite the outlet end of the water inlet pipe 11. A second traction rope 36 is fixedly attached to the bottom of the other end of the rotating rod 24. A trigger is fixedly attached below the second traction rope 36. A counterweight 26 is slidably connected above the rotating rod 24. (Refer to...) Figure 3When the water container 21 moves to its lower limit position, it pulls down the second traction rope 36. The second traction rope 36 pulls the rotating rod 24, which rotates clockwise, causing the plug 23 to block the outlet end of the water inlet pipe 11. At the same time, the counterweight 26 slides to the rightmost side of the rotating rod 24, keeping the plug 23 blocking the outlet end of the water inlet pipe 11. When the water container 21 moves to its uppermost limit position, it pushes the rotating rod 24 to rotate counterclockwise, causing the plug 23 to loosen. At the same time, the counterweight 26 slides to the leftmost side of the rotating rod 24, keeping the rotating rod 24 tilted to the left.
[0030] The scheme is further optimized. The triggering part includes several second slide rails 22, which are fixedly connected to the bottom of the power chamber 5. The second slide rails 22 are vertically arranged and slidably connected to the same slider 34. The top of the slider 34 is fixedly connected to the bottom of the second traction rope 36. A fixing block 35 is fixedly connected to the bottom of the water container 21. The fixing block 35 is opposite to the slider 34. A column 20 is fixedly connected to the side wall of the water container 21. The column 20 is vertically arranged and its top is opposite to the end of the rotating rod 24 near the first traction rope 18. When the water container 21 moves to the lower limit position, the fixing block 35 at the bottom of the water container 21 pushes the slider 34 to move downward along the second slide rail 22, and the slider 34 pulls the second traction rope 36 downward. When the water container 21 moves to the upper limit position, the column 20 fixed to the side wall of the water container 21 pushes the rotating rod 24 near the end of the first traction rope 18, causing the rotating rod 24 to rotate counterclockwise.
[0031] The design is further optimized so that the traction rope guide section includes a third rotating shaft 16. The two ends of the third rotating shaft 16 are rotatably connected to the side wall of the power chamber 5. The third rotating shaft 16 is arranged parallel to the second rotating shaft 15. A roller 17 is fixedly connected to the middle of the third rotating shaft 16, and the first traction rope 18 passes over the roller 17. The third rotating shaft 16 can prevent the second traction rope 36 from interfering with other components.
[0032] In a further optimized design, a door panel 10 is rotatably connected to the top of the storage chamber 3 via a hinge 28. The door panel 10 has several water holes 29. After opening the door panel 10, the blockage can be cleared out of the storage chamber 3.
[0033] In a further optimized design, the bottoms of the utility chamber 3 and the power chamber 5 are connected to the well body 1 via a drainage pipe 2. Wastewater from the utility chamber 3 and the power chamber 5 enters the well body 1 through the drainage pipe 2, and the utility chamber 3 and the power chamber 5 are separated by a partition 4.
[0034] The working process of this embodiment is as follows: Debris carried in the sewage will clog the manhole cover 6, causing sewage to accumulate. When the sewage accumulates to a certain extent, it will flow from the inlet pipe 11 at the roadside shoulder 9 into the power chamber 5 and into the water container 21. The inflow of water into the water container 21 is much greater than the outflow, causing the weight of the water container 21 to increase rapidly and move downwards. This causes the second rotating shaft 15 to rotate via the first traction rope 18. The rotation of the second rotating shaft 15 drives the second gear 14 to rotate. The second gear 14, through meshing with the first gear 13, drives the first rotating shaft 12 to rotate. The first rotating shaft 12, through the driven gear 31, drives the toothed plate 8 to move linearly, extending the toothed plate 8 outside the debris chamber 3. At this time, the water container 21 moves to its lower limit position. The fixed block 35 at the bottom of the water container 21 pushes the slider 34 to move downwards along the second slide rail 22. The slider 34 pulls the second traction rope. 36 moves downwards, the second traction rope 36 pulls the rotating rod 24, the rotating rod 24 rotates clockwise, causing the plug 23 to block the outlet end of the water inlet pipe 11. At the same time, the counterweight 26 slides to the rightmost side of the rotating rod 24, keeping the plug 23 blocking the outlet end of the water inlet pipe 11. The sewage in the water container 21 gradually leaks out. After the sewage in the water container 21 is emptied, the coil spring 30 drives the first rotating shaft 12 to reverse, thereby driving the water container 21 to move upward to the upper limit position. During this process, the toothed plate 8 retracts, and the scraper 7 collects the blockage into the debris chamber 3, driving the column 20 fixed to the side wall of the water container 21 to push the rotating rod 24 close to one end of the first traction rope 18, causing the rotating rod 24 to rotate counterclockwise, so that the outlet end of the water inlet pipe 11 is opened again, repeating the process of sewage entering the water container 21, thereby driving the scraper 7 to reciprocate to scrape the blockage on the grate 6 clean.
