Description

Technical Field

[0001] This invention belongs to the field of municipal road technology, and in particular relates to a municipal road drainage pipe anti-clogging system. Background Technology

[0002] Currently, drainage pipe blockage is a widespread problem. During rainy days, rainwater washes away road surfaces, carrying various solid debris and mud into the drainage pipes. As the water flow slows, solid debris settles due to gravity, and mud also settles. If not cleaned promptly, this accumulation will eventually block the drainage pipes, reducing the cross-sectional area for water flow, decreasing water carrying capacity, and even causing some areas to lose their drainage system function, resulting in flooding every time it rains. Existing drainage pipe anti-blockage measures, such as installing filter plates, have problems such as filter plate accumulation easily clogging the pipes, requiring frequent cleaning, and affecting efficiency during periods of high drainage volume. Some anti-blockage devices also have shortcomings, such as being unable to effectively crush debris flowing into the drainage pipes from the outside.

[0003] Based on this, the present invention designs a municipal road drainage pipe anti-clogging system to solve the above problems. Summary of the Invention

[0016] 2. In this invention, by setting an anti-backflow device at the bottom of the filtration zone and a second anti-backflow device at the bottom of the second drain pipe, the anti-backflow road drainage structure can effectively prevent the backflow of water, reduce the risk of flood disasters, ensure the efficient operation of the road drainage system, and minimize water accumulation. It can not only improve the efficiency and reliability of the drainage system, but also protect the environment, ensure traffic safety, and reduce the risk of urban flooding, thus having significant social and economic benefits.

[0017] 3. In this invention, filter residue can be collected by setting up a filter residue collection tank, and the filter residue can be crushed by a crusher. The crushed filter residue will be further filtered by the third filter plate, and then the crushed filter residue will be discharged through the filter residue hopper and the elevator. Rainwater will flow into the drain pipe through the third filter plate to complete the drainage, and the rainwater in the slag discharge area will flow into the second drain pipe through the fourth filter plate to complete the drainage. This ensures the efficient operation of the drainage system under different conditions, optimizes the drainage process, and improves drainage efficiency. Attached Figure Description

[0032] Reference Figure 1A municipal road drainage pipe anti-clogging system includes an anti-clogging drainage zone 1, with a drainage pipe 7 connected to the bottom of the anti-clogging drainage zone 1 and the top of the anti-clogging drainage zone 1 connected to the outside. A filtration zone 2 is provided in the anti-clogging drainage zone 1, a first filter residue zone 3 is provided on the left side of the filtration zone 2, and a second filter residue zone 4 is provided on the right side of the filtration zone 2. The bottom of the filtration zone 2, the first filter residue zone 3, and the second filter residue zone 4 are all connected to a filter residue crushing zone 8. A slag collection zone 9 is connected to the right side of the filter residue crushing zone 8, and a slag discharge zone 5 is provided on the right side of the slag collection zone 9. A drainage outlet 6 is also provided at the top of the filtration zone 2.

[0033] Reference Figure 2-4 The filter zone 2 is equipped with a filter device 10 and an anti-backflow device 11. The filter device 10 includes a first filter plate 12 and a second filter plate 13. The diameter of the first filter plate 12 is larger than that of the second filter plate 13. Each of the four bottom corners of the first filter plate 12 and the second filter plate 13 has a protrusion 19. Multiple slots 20 are provided at the four corners of the inner wall of the filter zone 2. The protrusions 19 are inserted into the slots 20. This connection method makes the entire installation process more stable and prevents the filter plates from shifting due to water flow impact. The first filter plate 12 and the second filter plate 13 are respectively equipped with a first moving strip 14 and a second moving strip 15. The left and right walls of the filter zone 2 have first openings 18 corresponding to the first moving strips 14 and 15. The left and right sides of the first moving strip 14 are respectively connected to a first traction rope 16 and a first compression spring 25. The left and right sides of the second moving strip 15 are respectively connected to a second traction rope 17 and a second compression spring 26. A first pulley 2 is provided on the right side wall of the first filter residue zone 3. 2. The first traction rope 16 and the second traction rope 17 are respectively wound around the first pulley 22 and the second pulley 23. The other end of the first traction rope 16 and the second traction rope 17 are connected to the rope coiling machine 24. The other end of the first compression spring 25 and the second compression spring 26 are fixedly connected to the inner wall of the second filter cake area. Two first detection devices 21 are also provided on the inner wall of the right side of the filter area 2. The two first detection devices 21 are used to detect the filter cake condition of the first filter plate 12 and the second filter plate 13. When there is too much filter cake and it may cause the filter plate to be blocked, a warning signal will be issued, and then the rope coiling machine 24 will be started. The rope coiling machine 24 will shrink the rope length, which will drive the moving bar to move to the left, thereby clearing the filter cake on the filter plate. Then the rope coiling machine 24 will stop working. When the filter cake on the filter plate may cause blockage again, the detection device will issue a warning signal again, and then the rope coiling machine 24 will be started. The rope coiling machine 24 will extend the rope length, and the moving bar will be moved to the right by the compression spring, thereby clearing the filter cake on the filter plate.

[0034] Reference Figure 2Figure 5 shows that the bottom of the filter device 10 is also equipped with an anti-backflow device 11. The anti-backflow device 11 includes a fixing frame 27 set on the inner wall of the filter zone 2. A water collection tank 28 is fixedly connected to the fixing frame 27. A bottom plate 29 is connected to the bottom of the water collection tank 28. A fixing plate 30 is also set at the bottom of the bottom plate 29. One end of the fixing plate 30 is connected to the inner wall of the filter zone 2. A limiting plate 31 is also fixed on the bottom wall of the fixing plate 30. The limiting plate 31 is inclined to the horizontal ground. The bottom plate 29 is fixed by hinge through the fixing plate 30. When the road is drained, the bottom plate 29 opens the lower port of the water collection tank 28 under the impact of the water flow to ensure normal drainage. Because the bottom plate 29 is always in an inclined state with respect to the vertical plane under the action of the limiting plate 31, when water backflow occurs, the bottom plate 29 will block the lower port of the water collection tank 28 under the impact of the water flow to prevent water from passing through the water collection tank 28.

[0035] Reference Figure 2 Figure 6 shows a filter cake collection trough 32 at the bottom of the first filter cake zone 3. A first moving plate 35 is located at the bottom of the filter cake collection trough 32. The piston of a first cylinder 34 is connected to the right side of the first moving plate 35. The first cylinder 34 is fixedly connected to the inner left wall of the first filter cake zone 3. A second detection device 33 is located on the inner left wall of the filter cake collection trough 32. The second detection device 33 is used to detect the amount of filter cake in the filter cake collection trough 32. When the amount of filter cake reaches the set amount, a warning message will be issued. Upon receiving the instruction, the first cylinder 34 will retract the length of the piston, thereby driving the first moving plate 35 to move to the left, causing the filter cake in the filter cake collection trough 32 to flow into the crusher 36 for crushing. The filter cake in the filter zone 2 and the second filter cake zone 4 will also all flow into the crusher 36 for crushing.

[0036] Referring to Figure 2, a slag collection area 9 is located on the right side of the crusher 36. A third filter plate 38 is located at the bottom of the slag collection area 9. A third detection device 37 and a second cylinder 39 are located at the top of the slag collection area 9. A second moving plate 40 is fixedly connected to the piston output end of the second cylinder 39. When the third detection device 37 detects that there is too much crushed filter residue in the slag collection area 9, which may affect the third filter plate and cause blockage or overfilling, it will issue a warning and activate the second cylinder 39. The second cylinder 39 retracts its piston, thereby driving the second moving plate 40 to move upwards. The filter residue is collected in the slag discharge area 5, which is equipped with a filter residue hopper 41. The bottom of the filter residue hopper 41 is equipped with a filter layer, so that the rainwater entering the filter residue hopper 41 will seep out from the bottom and then be discharged from the fourth filter plate 43 on the side wall of the slag discharge area 5 into the second drain pipe 49. The second drain pipe 49 is also equipped with a second anti-backflow device 50. The filter residue hopper 41 is connected to the elevator 42. When the filter residue hopper 41 is full of filter residue, the filter residue in the filter residue hopper 41 is removed by the elevator 42 to achieve the purpose of circulating filtration and unloading.

[0037] Reference Figure 2 The second anti-backflow device 50 includes a second fixing frame 44 installed on the side wall of the second drain pipe 49. A second water collection tank 45 is fixedly connected to the second fixing frame 44. A second base plate 46 is installed at the bottom of the second water collection tank 45. A second fixing plate 47 is also installed at the bottom of the second base plate 46. One end of the second fixing plate 47 is connected to the inner wall of the second drain pipe 49. A second limiting plate is also fixed on the bottom wall of the second fixing plate 47. The second limiting plate is inclined to the horizontal ground. The second base plate 46 is fixed by hinge to the second fixing plate 47, thereby preventing the backflow of rainwater in the second drain pipe 49.

[0038] Working principle: First, rainwater from municipal roads is collected through drainage ditches and discharged into the anti-clogging drainage zone 1. The rainwater then flows into the filtration zone 2 through the drain outlet 6. The filtration device 10 in the filtration zone 2 initially filters impurities from the rainwater through the first filter plate 12 and the second filter plate 13. When the first detection device 21 detects that the filter residue on the first filter plate 12 or the second filter plate 13 may cause excessive filter plate clogging, the rope coiling machine 24 is activated to pull the traction rope, thereby driving the first moving bar 14 and the second moving bar 13. The moving bar 15 collects the filter residue above the first filter plate 12 and the second filter plate 13 into the first filter residue area 3 or the second filter residue area 4. The filter residue collected into the first filter residue area 3 will first be concentrated in the filter residue collection tank 32. When the second detection device 33 detects that the filter residue in the filter residue collection tank 32 is relatively full, it will issue a warning message. The control center will issue a command to start the first cylinder 34 to retract the piston, thereby opening the bottom of the filter residue collection tank 32 and collecting the filter residue into the crusher 36 for crushing. After crushing, the filter residue is transported to the residue collection area 9.

[0039] On the other hand, the filter residue flowing into the second filter residue zone 4 will be directly fed into the crusher 36 for crushing. After crushing, the filter residue will also be transported to the residue collection zone 9. The bottom of the residue collection zone 9 is equipped with a third filter plate 38. The third filter plate 38 will collect the water in the crushed filter residue into the drain pipe 7. When the third detection device 37 detects that the filter residue in the residue collection zone 9 is too full or may cause blockage, it will issue a warning message. The control center will issue a command to start the second cylinder 39. The second cylinder 39 drives the second moving plate 40 to move upward to open the opening of the side wall, collect the filter residue into the filter residue hopper 41, and then transport it away through the elevator 42 to complete the process of cleaning the filter residue.

[0040] On the other hand, the filter layer at the bottom of the filter hopper 41 can filter out the rainwater in the filter residue. The rainwater flows from the fourth filter plate 43 on the right side wall of the slag discharge area 5 into the second drain pipe 49. The second drain pipe 49 is equipped with a second anti-backflow device 50, which can further prevent the backflow of rainwater in the second drain pipe 49.
