Description

Technical Field

[0001] The utility model relates to the technical field of manhole covers, in particular to a municipal sewer anti-blocking manhole cover. Background Art

[0002] A sewer is a kind of urban public facility, which refers to the pipes used by buildings to discharge sewage and rainwater; it also refers to the underground passages used by cities, factories or villages to discharge sewage and rainwater. The section from the sewer pipe to the ground is called a manhole. The manhole opening is usually flush with the ground, so a cover is needed. The cover used to cover the manhole is called a manhole cover.

[0003] The existing patent with the authorization announcement number "CN218508640U" discloses a municipal sewer manhole cover, including a manhole cover body, a mounting base and a mounting mechanism. The bottom of the manhole cover body is provided with a mounting base, and the outer surface of the mounting base is provided with a mounting mechanism. The municipal sewer manhole cover, through the provided discharge trough seat, sleeve seat and movable valve plate, when drainage is not caused by flooding, the movable valve plate is sealed inside the discharge trough seat, so that some debris cannot fall into the sewer pipe through the penetration hole of the manhole cover to cause pipe blockage. When mechanical drainage operation is required, the valve control wheel is rotated to drive the connecting rod to rotate, and the sleeve seat is rotated after the connecting rod is rotated to open the movable valve plate, thereby controlling the size of the hole slot during circulation, thereby increasing the practicality of the manhole cover.

[0004] However, there are the following deficiencies in this device:

[0005] 1. When the accumulated water on the road is discharged into the sewer through the manhole cover, the accumulated water will contain dust and other garbage. However, when the above device is used, the garbage in the accumulated water is not removed, which makes the sewer easy to be blocked, reducing the anti-blocking performance of the device;

[0006] 2. The drain outlet of the manhole cover is often blocked by garbage such as leaves and plastic bags, thus affecting the drainage of the manhole cover. However, when the above device is in use, it is difficult to automatically clean the garbage at the drain outlet, and sanitation workers are required to clean it frequently, which is not convenient to use.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides an embodiment of a municipal sewer anti-blocking manhole cover, comprising a cover body 1 and a cover plate 5. The bottom of the cover body 1 is provided with a filter groove 10. Six groups of drain outlets 2 connected to the filter groove 10 are opened at the edge of the top of the cover body 1. A filter cartridge 7 is provided in the middle of the top of the inner side of the filter groove 10. A receiving groove 3 is opened in the middle of the top of the cover body 1. Connecting rods 6 are sleeved on both sides of the bottom of the inner side of the receiving groove 3. The bottoms of the two groups of connecting rods 6 extend to the inner side of the filter groove 10 and are provided with an annular floating plate 9. The inner side of the annular floating plate 9 is provided with a scraper 8 that matches the filter cartridge 7. A pressing block 4 is jointly provided on the top of the two groups of connecting rods 6. The pressing block 4 is in the shape of a truncated cone, so that when a vehicle rolls the pressing block 4, it will not affect the driving of the vehicle and cause greater interference. Slots 23 are opened on both sides of the cover plate 5. The bottoms of both sides of the filter groove 10 are threadedly connected with threaded rods 22. An anti-blocking component is provided inside the cover body 1.

[0024] Furthermore, the anti-blocking component includes a hemispherical block 12, a push rod 13, an active groove 14, a mounting groove 15, an air inlet pipe 16, a one-way valve A17, a piston 18, a piston cylinder 19, a one-way valve B20 and an exhaust pipe 21. The cover body 1 is provided with a mounting groove 15, and six groups of active grooves 14 are provided on the top of the cover body 1 near the drain port 2. Six groups of piston cylinders 19 are evenly arranged at the bottom of the mounting groove 15. The top of the piston cylinder 19 is sleeved with a push rod 13. The top of the push rod 13 extends to the inner side of the active groove 14 and is provided with a hemispherical block 12. The outer side of the push rod 13 is sleeved with a hemispherical block 12. A spring 11 is connected to the ball block 12, and a piston 18 matching with a piston cylinder 19 is provided at the bottom of the push rod 13. A one-way valve B20 and a one-way valve A17 are respectively provided at the bottom of both sides of the piston cylinder 19. An exhaust pipe 21 connected to the drain port 2 is provided on one side of the one-way valve B20, and an air intake pipe 16 is provided on one side of the one-way valve A17. The end of the air intake pipe 16 extends to the top of the cover body 1, so that the air flow can enter the piston cylinder 19 from the air intake pipe 16. When a vehicle passes the top of the cover body 1, the hemispherical block 12 can be rolled to drive the air flow to blow out, so as to blow away the garbage on the top of the drain port 2.

[0025] Furthermore, a limiting ring is provided at the bottom of the inner wall of the filter tank 10 , and the cover plate 5 can be positioned by the limiting ring, so that the cover plate 5 can be easily installed.

[0026] Furthermore, pull rings are provided on both sides of the bottom of the cover plate 5, and a through hole adapted to the filter cartridge 7 is opened in the middle of the bottom of the cover plate 5. The pull rings are used to facilitate taking the cover plate 5, and the cover plate 5 can be stuck on the outside of the filter cartridge 7 through the through hole.

[0027] Working principle: When the device is in use, the cover body 1 can be installed at the road sewer outlet for use. When water accumulates on the road surface, the drain outlet 2 can be used to block large-volume garbage such as leaves and plastic bags in the accumulated water, and then the accumulated water can enter the filter tank 10 through the drain outlet 2. After the accumulated water enters the filter tank 10, the muddy garbage in the accumulated water can be filtered through the filter cartridge 7, and the filtered accumulated water can be discharged into the sewer to prevent the muddy garbage from clogging the sewer;

[0028] When the filter cartridge 7 is clogged with sludge, the water level in the filter tank 10 will gradually rise, and the annular floating plate 9 can move up with the water level under the action of buoyancy, and drive the pressing block 4 to move up through the connecting rod 6. At this time, pedestrians or vehicles passing by can step on or roll the pressing block 4 to move down, and then the pressing block 4 can drive the annular floating plate 9 to move down, and the filter cartridge 7 is cleaned and dredged by the scraper 8, thereby improving the convenience of dredging the filter cartridge 7;

[0029] When it is necessary to clean the garbage in the filter tank 10, the cover body 1 can be opened, and then the threaded rod 22 can be rotated and pulled out from the slot 23 to release the fixing of the cover plate 5. The cover plate 5 can be removed to clean the garbage in the filter tank 10;

[0030] When a vehicle passes the top of the cover body 1, it will roll onto the hemispherical block 12. At this time, the hemispherical block 12 can overcome the elastic force of the spring 11 and move downward, and drive the piston 18 to move downward through the connection of the push rod 13. The piston 18 can squeeze the air flow in the piston cylinder 19 to be discharged from the one-way valve B20, and then blown to the top of the drain outlet 2 through the diversion of the exhaust pipe 21, so that garbage such as leaves and plastic bags on the top of the drain outlet 2 can be blown away. The elastic force of the spring 11 can push the hemispherical block 12 to reset. At this time, the piston 18 moves up, and the air flow can enter the piston cylinder 19 from the one-way valve A17 through the diversion of the intake pipe 16. In this way, the garbage on the top of the drain outlet 2 can be repeatedly and continuously cleaned to prevent the drain outlet 2 from being blocked and affecting the drainage of the device.
