Description

Technical Field

[0001] The invention relates to the technical field of manhole covers, in particular to a flood-proof manhole cover. Background Art

[0002] Manhole covers play an important role in urban management. They are usually used to cover the wellheads of inspection wells, rainwater wells, sewage wells, cable wells, etc. in roads or communities. They can ensure the safety of pedestrians and vehicles and avoid accidental injuries caused by exposed wellheads. As cities expand, the area of ​​hardened ground continues to increase. When it rains, rainwater on the road is mainly discharged by related rainwater drainage facilities such as rainwater wells, and then merged into the city's underground drainage system for centralized external discharge.

[0003] At present, the manhole covers of rainwater wells and related rainwater drainage facilities are mainly mesh-type, and rainwater is discharged through the holes on the manhole covers. When the rainfall is greater than the drainage capacity of the manhole covers, water will accumulate on the road. Since the manhole covers are fixed, the drainage capacity cannot be expanded, which leads to increasingly serious water accumulation. At present, for seriously flooded roads, people mainly remove the manhole covers to increase the drainage capacity, or configure waterlogging rescue vehicles to actively send water out through pumps. Both methods require manual work on site, and the treatment of water accumulation is not fast enough. Summary of the invention

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present invention provides a flood-proof manhole cover, which has the following beneficial effects:

[0018] 1. The manhole cover supports the cover plate of the manhole body through a telescopic rod. When water accumulates on the road, the cover plate can be raised by controlling the telescopic rod to increase the gap between the cover plate and the manhole body, thereby increasing the amount of rainwater discharged, accelerating the drainage of accumulated water, and thus alleviating or solving the problem of water accumulation on the road. Manual operations do not need to be carried out on site, and a quick response to water accumulation on the road can be achieved.

[0019] 2. The manhole cover uses a ball block and a fixed block to provide displacement of the telescopic rod relative to the cover when it is lifted. The contact surface between the ball block and the slide groove is smaller, and sliding is relatively easier, thereby better ensuring the smooth rise or fall of the cover.

[0020] 3. This manhole cover, when used with a liquid level meter, can quickly and in real time understand the current water accumulation situation on the road, so that timely response can be made, and the road water accumulation treatment is more timely and rapid.

[0021] 4. This manhole cover can block larger debris such as leaves during the discharge process by adding a mesh cover between the cover and the manhole body.

[0022] 5. This manhole cover has an indicator light added to the top of the cover. When the cover is raised to accelerate drainage, the indicator light can light up simultaneously to remind passers-by and vehicles, thereby improving safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] See also Figure 1-7The top surface of the cover plate 1 is flush with the road surface of the roadbed 11, and a plurality of fixing blocks 2 are installed with bolts at equal intervals on the bottom surface of the cover plate 1. A slide groove 3 is preset in the fixing block 2, and a limiting strip opening 4 connected to the slide groove 3 is opened on the bottom surface of the fixing block 2. The length and width of the limiting strip opening 4 are both smaller than the length and width of the slide groove 3. A ball block 5 sliding along the slide groove 3 is provided in the slide groove 3, and a fixing plate 6 is welded and installed at the bottom of the ball block 5. A telescopic rod 7 is hingedly installed at the position of the fixing plate 6 through a pin shaft 9. The telescopic rod 7 is any one of electric, pneumatic and hydraulic types. The telescopic rod 7 in this embodiment is a hydraulic telescopic rod, and the other end of the telescopic rod 7 away from the ball block 5 is hingedly installed with an articulated seat 8 through a pin shaft 9, and the articulated seat 8 is fixed to the inner wall of the corresponding position of the well body 10 by bolts;

[0033] The well body 10 is built on the top of the drainage channel 12 in the roadbed 11. The well body 10 is connected to the drainage channel 12. According to the length of the road, the well body 10 is set in multiple ways according to the road design requirements. The well body 10 is set at a position close to the curb 13 of the roadbed 11. A liquid level meter 14 is installed on the curb 13 close to the cover plate 1 facing the roadbed 11. The liquid level meter 14 is a capacitive liquid level meter.

[0034] When in use, the liquid level meter 14 detects the depth of water accumulation on the road surface. When it rains, rainwater first collects to the well body 10 through the bottom surface, first flows into the well body 10 through the gap between the cover plate 1 and the well body 10, and then falls into the drainage channel 12 for centralized discharge through the city's underground drainage system. When the amount of rainfall is greater than the amount of rainwater discharged through the gap between the cover plate 1 and the well body 10, rainwater will accumulate on the road surface at the position of the cover plate 1, and then water accumulation will begin to occur. When the accumulated water overflows into the liquid level meter 14, the water accumulation depth value at the current position can be obtained through capacitive sensing. When the water accumulation depth is deep, the telescopic rod 7 can be controlled to lift. When all the telescopic rods 7 are extended equally, the ball block 5 will be pushed in the slide groove 3 toward the middle of the cover plate 1. The cover plate 1 moves in the direction of the space between the cover plate 1 and the well 10, and at the same time pushes the cover plate 1 to rise. The height of the cover plate 1 from the road surface after reaching the maximum lifting limit is preset to 5 cm. The cover plate 1 is 2 cm thick and can also be adjusted as needed. After the cover plate 1 is pushed and raised by the telescopic rod 7, the gap between the cover plate 1 and the well body 10 for rainwater drainage is enlarged, thereby increasing the drainage volume per unit time. At this time, if the rainfall is less than the drainage volume, the accumulated water will be continuously consumed, thereby alleviating and solving the problem of road surface waterlogging. When the accumulated water continues to be discharged for relief, the accumulated water level obtained by the position detection of the liquid level meter 14 continues to decline. When it drops to a certain value, the telescopic rod 7 can be controlled again to control it to retract, thereby driving the cover plate 1 to drop to the same level as the road surface.

[0035] In this embodiment, the cover plate 1 is arranged in an equilateral heptagonal structure, the seven sides of the cover plate 1 are all arranged in arc shape to form a Reuleaux heptagon, and the fixing blocks 2 are arranged at the seven corner positions corresponding to the bottom surface of the cover plate 1.

[0036] The heptagon is equal to the number of telescopic rods 7, which is seven. Multiple telescopic rods 7 can share the gravity effect on the cover 1 when a car passes by, thereby maintaining the stability of the cover 1 and preventing it from falling. The sides of the Leroy heptagon are arc-shaped. When the cover 1 rises and protrudes from the road surface and is run over by a vehicle, the direct impact strength between the tire and the cover 1 can be reduced. At the same time, it is also beneficial to the support balance of the telescopic rods 7 in all directions, and the sharpness of the corners is also weakened, reducing damage to the tire.

[0037] In the present embodiment, a mesh cover 15 is installed at the gap position between the well body 10 and the cover plate 1, and the mesh cover 15 includes an outer ring frame 16. The inner wall of the well body 10 near the top position is preset with a mounting recess 21, and the outer ring frame 16 is arranged between the mounting recess 21 and the outer wall of the cover plate 1. The bottom surface of the outer ring frame 16 near the outer periphery falls on the well body 10 at the position of the mounting recess 21 to form a placement support. A leak plate 18 is provided directly below the cover plate 1. The leak plate 18 and the outer ring frame 16 are integrally connected by a connecting plate 17. The cross-section of the connecting plate 17 is arranged in an L-shaped structure. Dense water leakage holes 19 are opened on the outer ring frame 16, the connecting plate 17 and the leak plate 18. A reserved opening 20 is provided on the leak plate 18 corresponding to the position of the fixed block 2. The fixed block 2 is located in the reserved opening 20, and the height of the fixed block 2 is greater than the maximum height from the ground after the cover plate 1 is raised.

[0038] The outer ring frame 16 fills the gap between the well body 10 and the cover plate 1. When acting on the non-motorized vehicle lane, pedestrians walking or bicycles and electric vehicles with relatively narrow wheels can be prevented from falling into the gap and causing falls. At the same time, since the height of the fixed block 2 is greater than the maximum height from the ground after the cover plate 1 is raised, when the cover plate 1 is raised, the reserved opening 20 can not only be used to limit the cover plate 1 so that it can rise or fall horizontally, but the fixed block 2 is always in the reserved opening 20. Large debris such as leaves brought by accumulated water are not easily stuck between the fixed block 2 and the reserved opening 20 after passing through the leakage hole 19, affecting the subsequent descent of the cover plate 1. The leakage holes 19 on the outer ring frame 16, the connecting plate 17 and the leakage plate 18 allow rainwater to continue to drain and block the leaves.

[0039] In this embodiment, a plurality of indicator lights 22 are pre-buried on the top surface of the cover plate 1 near the outer periphery.

[0040] During installation, the indicator light 22 is powered simultaneously. When the telescopic rod 7 is lifted and drives the cover plate 1 to rise, the synchronously controlled indicator light 22 is powered on and starts to emit light to remind passing vehicles or pedestrians to pay attention to the rising cover plate 1, thereby reducing the speed of the vehicle to pass or bypass it, reducing the adverse effects caused by the protrusion of the cover plate 1.
