[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0030] Refer to Figure 1 、 Figure 2 、 Figure 3, An embodiment provided by the utility model: an adjustable manhole cover structure for municipal roads, including a wellhead body 1. A manhole cover body 2 is snap - connected to the upper side inside the wellhead body 1, and a filter plate 19 is snap - connected to the lower side inside the wellhead body 1 to separate the connections in the water flow. An inner cylinder 24 is fixedly connected to the upper part of the filter plate 19. Two first connection seats 12 are fixedly connected to the bottom side inside the inner cylinder 24. A connection frame 15 is rotatably connected inside the first connection seat 12. The upper end outside of the connection frame 15 is rotatably connected to a second connection seat 13. A connecting plate 10 is fixedly connected to the upper part of the second connection seat 13. The connecting plate 10 is fixedly connected to the manhole cover body 2 through bolts 5, so that the manhole cover body 2 can be pulled to keep it at the same horizontal line as the road surface. First telescopic members 11 are fixedly connected to both the left and right sides of the bottom of the connecting plate 10. An articulated frame 14 is slidably connected to the outside of the connection point of the connection frame 15. Reset elastic components are fixedly connected to both the left and right sides of the inner wall of the articulated frame 14. The elastic components are used to pull down the manhole cover body 2 to make it flush with the wellhead body 1, automatically pulling the manhole cover body 2 to adjust its height;
[0031] The elastic component includes a first spring 18. The first spring 18 is fixedly connected to one side of the inner wall of the articulated frame 14. The corresponding end of the first spring 18 is fixedly connected to a connection block 17. The connection block 17 is fixedly connected to the connection point of the connection frame 15, so that when the articulated frame 14 rotates, it can be pushed, reducing the vibration generated when the wheel rolls; Slide grooves 16 are respectively opened at the upper and lower parts of both the left and right sides inside the articulated frame 14. The connection frame 15 is slidably connected inside the slide grooves 16, so that the articulated frame 14 can be folded to pull the manhole cover body 2; Limit blocks 8 are fixedly connected to both the left and right sides of the outside of the connecting plate 10. Limit grooves 9 are respectively opened at both the left and right sides inside the inner cylinder 24. The limit blocks 8 are slidably connected inside the limit grooves 9 to ensure the smooth movement of the connecting plate 10.
[0032] When there is a height difference between the wellhead body 1 and the manhole cover body 2 due to ground settlement, the connecting plate 10 is pulled through the second connection seat 13. Under the action of the connection between the connecting plate 10 and the manhole cover body 2 through bolts 5, the manhole cover body 2 is pulled downwards. The articulated frame 14 is squeezed and rotated inside the first connection seat 12 and the second connection seat 13. Through the rotation of the articulated frame 14, the connection point slides inside the connection frame 15, and the connection block 17 is pushed, squeezing the first spring 18. At the same time, it slides inside the slide grooves 16 on both the upper and lower sides, causing the connection frame 15 to move downwards. And when the connecting plate 10 moves downwards, the limit blocks 8 are driven, sliding inside the limit grooves 9, squeezing the first telescopic members 11. When the road surface sinks, the manhole cover body 2 can be synchronously driven to ensure that it is at the same level as the road surface, avoiding safety threats caused by uneven road surfaces.
[0033] Refer to Figure 1 、 Figure 2 、 Figure 4, there are five water inlets 4 opened inside the manhole cover body 2. A hinge 6 is fixedly connected to one side close to the inside of the water inlet 4. The upper part of one side of the hinge 6 is fixedly connected to a rotating plate 7. The rotating plate 7 is rotatably connected inside the water inlet 4 to ensure that water can be discharged in time. One side of the bottom of the rotating plate 7 is rotatably connected to a first rotating bead 20. One side of the first rotating bead 20 is fixedly connected to a second telescopic member 21. The corresponding ends of the second telescopic members 21 are fixedly connected to a second rotating bead 23. The second rotating bead 23 is rotatably connected inside the inner cylinder 24. A second spring 22 is sleeved outside the second telescopic member 21 to automatically adjust the water discharge efficiency;
[0034] One end of the second spring 22 is fixedly connected to the outside of one side of the first rotating bead 20, and the other end of the second spring 22 is fixedly connected to the outside of one side of the second rotating bead 23, so that the rotating plate 7 can automatically reset when the pressure decreases; A filter screen 3 is fixedly connected inside the water inlet 4 to initially block the garbage in the water flow; The rotating plate 7 is rotatably connected inside the water inlet 4.
[0035] The filter screen 3 blocks the garbage in the water flow, and the pressure of the water flow pushes the rotating plate 7 to rotate and open, so that the water flow enters the inside of the water inlet 4 and is discharged. When the water flow is larger, the thrust on the rotating plate 7 is greater. When the rotating plate 7 rotates, the first rotating bead 20 squeezes the second telescopic member 21 and the second spring 22 to generate a resilience force. After the water flow decreases, the rotating plate 7 is pulled back to its original position by the resilience force of the second telescopic member 21 and the second spring 22. At the same time, the second rotating bead 23 rotates inside the inner cylinder 24 to ensure the normal rotation of the rotating plate 7, so that it can be automatically adjusted when the water flow is too large to ensure that the water flow can be discharged in time and avoid water accumulation.
[0036] Working principle: When the ground sinks, the connecting plate 10 pulls the manhole cover body 2 through the second connecting seat 13, so that the hinge frame 14 is squeezed and rotated inside the first connecting seat 12 and the second connecting seat 13. Through the rotation of the hinge frame 14, the transfer point moves inside the connecting frame 15, and the first spring 18 is squeezed by the connecting block 17, so that the connecting frame 15 moves downward. At the same time, when the connecting plate 10 moves downward, the limiting block 8 is driven to squeeze the first telescopic member 11, realizing that when the road surface sinks, the manhole cover body 2 can be driven synchronously to ensure the same height and avoid the safety threat caused by the uneven road surface;
[0037] When the water flow is larger, the thrust on the rotating plate 7 is greater. When the rotating plate 7 rotates, the first rotating bead 20 squeezes the second telescopic member 21 and the second spring 22. At the same time, the second rotating bead 23 rotates inside the inner cylinder 24 to ensure the normal rotation of the rotating plate 7, realizing automatic adjustment when the water flow is too large to ensure that the water flow can be discharged in time and avoid water accumulation.
[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
