Description

Technical Field

[0001] This utility model applies to the field of manhole cover technology and provides an environmentally friendly composite material municipal manhole cover. Background Technology

[0002] In municipal infrastructure construction, environmentally friendly composite material manhole covers are widely used in urban roads, sidewalks, green belts and other areas due to their environmentally friendly characteristics such as light weight, corrosion resistance and recyclability. They play an important role in covering underground pipe well openings and ensuring the safety of pedestrians and vehicles.

[0003] However, existing environmentally friendly composite material municipal manhole covers still have significant functional limitations in actual use. When encountering severe weather such as rainstorms and short-term heavy rainfall, the amount of surface water in the city increases sharply. The manhole covers need to drain the water around the manhole opening through their pre-set drainage holes. However, due to the structural design of the composite material manhole covers and the size of the holes, their drainage efficiency is far from meeting the short-term heavy drainage needs. This can easily lead to the formation of water puddles around the manhole opening, which not only affects traffic but may also pose potential risks due to the water covering the manhole opening.

[0004] To solve the problem of water accumulation, in some scenarios, it is necessary to manually open the manhole cover to speed up the drainage. However, this will completely expose the manhole opening. Since the environmentally friendly composite material manhole cover is lightweight and lacks effective fixation, the opened manhole cover is easily displaced by the water flow or accidentally touched by pedestrians. Not only does it fail to form a stable drainage channel, but it also creates an open manhole hazard, increasing the risk of pedestrians and vehicles falling in and posing a threat to municipal public safety.

[0005] Therefore, this utility model provides an environmentally friendly composite material municipal manhole cover to solve the above problems. Utility Model Content

[0006] This invention provides an environmentally friendly composite material municipal manhole cover, which aims to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly composite material municipal manhole cover, including a manhole frame, on which a manhole cover is provided. An annular groove is formed on the outer surface of the top of the manhole cover, and multiple sets of fixing rods are fixedly installed at the bottom of the manhole cover. Limiting plates are fixedly installed at the ends of the multiple sets of fixing rods, and multiple sets of first limiting rods are fixedly installed at the top of the limiting plates. Adjusting plates are slidably installed on the multiple sets of first limiting rods, and locking components are provided on the adjusting plates for limiting and fixing the adjusting plates.

[0008] As a preferred technical solution of this application, the inner wall of the annular groove is provided with two sets of slots, the top outer surface of the adjusting plate is provided with two sets of grooves, the inner walls of the two sets of grooves are provided with multiple sets of mounting slots, the locking assembly includes springs fixedly installed in the multiple sets of mounting slots, the ends of the multiple sets of springs are fixedly connected with telescopic rods, the ends of the multiple sets of telescopic rods are fixedly connected with pull plates, and the side walls of the pull plates are fixedly connected with locking plates. The locking plates can be inserted into the slots to achieve locking, and the locking plates penetrate the adjusting plate.

[0009] As a preferred technical solution of this application, multiple sets of reinforcing blocks are fixedly installed on the well frame.

[0010] As a preferred technical solution of this application, a water inlet hole is provided on the outer surface of the top of the adjustment plate, which provides a channel for accumulated water to flow in.

[0011] As a preferred technical solution of this application, a limiting frame is fixedly installed on the inner wall of the well frame, and the limiting frame can limit the placement position of the well cover.

[0012] As a preferred technical solution of this application, a limiting block is fixedly installed at the top of multiple sets of the first limiting rods, and the limiting block can limit the sliding range of the adjusting plate at the top.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The adjustment plate can be unlocked by simply pulling the lever, allowing it to slide down and open the annular groove, forming a large drainage channel to quickly drain accumulated water. This process does not require opening the entire manhole cover, solving the problem of traditional manhole covers having to be opened due to slow drainage. Moreover, when the adjustment plate slides down to the limit plate, the manhole opening will not be completely exposed, fundamentally avoiding the potential danger of pedestrians or vehicles falling in after the manhole cover is opened, thus balancing drainage efficiency and safety.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] In this embodiment, the present invention provides an environmentally friendly composite material municipal manhole cover, as shown in the attached figure. Figure 1-6 As shown, the manhole includes a frame 1, on which a manhole cover 2 is mounted. An annular groove 6 is formed on the outer surface of the top of the manhole cover 2. This annular groove 6 is the core drainage expansion structure, which can form a large-diameter drainage channel during emergency drainage, solving the problem of low drainage efficiency caused by traditional manhole covers relying solely on small holes. Multiple sets of fixing rods 51 are fixedly installed at the bottom of the manhole cover 2, and limit plates 5 are fixedly installed at the ends of these fixing rods 51. The limit plates 5 provide a bottom support frame for the adjusting plate 3. The limit plates 5 both limit the downward movement of the adjusting plate 3 and form a safety shield after the adjusting plate 3 moves down, preventing the manhole opening from being completely exposed. Multiple sets of first limit rods 52 are fixedly installed at the top of the limit plates 5, and the adjusting plate 3 is slidably mounted on these first limit rods 52. The first limit rods 52 precisely guide the sliding direction of the adjusting plate 3, preventing it from shifting or tilting during sliding and ensuring stability during the adjustment process. A locking component is provided on the adjusting plate 3 for limiting and fixing its position.

[0024] The annular groove 6 has two sets of slots 21 on its inner wall, and the top outer surface of the adjusting plate 3 has two sets of grooves 31. The inner walls of the two sets of grooves 31 have multiple sets of mounting slots 32. The grooves 31 provide space for the operation of the pull plate 35, making it convenient for the operator to insert their fingers and exert force, thus improving the convenience of locking and adjusting. The locking component includes springs 33 fixedly installed in the multiple sets of mounting slots 32. The ends of the multiple sets of springs 33 are all fixedly connected to telescopic rods 34. The springs 33 can automatically reset the locking plate 36 without manually aligning the slots 21, simplifying the locking operation. The ends of the multiple sets of telescopic rods 34 are all fixedly connected to pull plates 35, and the side walls of the pull plates 35 are fixedly connected to locking plates 36. The locking plates 36 can be inserted into the slots 21 to achieve locking, and the locking plates 36 penetrate the adjusting plate 3. The pull plates 35 serve as operating handles, increasing the contact area for hand force application, making the pulling action during unlocking less strenuous. The design of the locking plates 36 penetrating the adjusting plate 3 ensures sufficient engagement depth and improves locking reliability.

[0025] Among them, multiple sets of reinforcing blocks 11 are fixedly installed on the manhole frame 1. The multiple sets of reinforcing blocks 11 can enhance the connection strength between the manhole frame 1 and the ground foundation, disperse the impact force of vehicle rolling on the manhole frame 1, reduce the settlement or loosening of the manhole frame 1 after long-term use, and avoid road collapse around the manhole cover.

[0026] The top outer surface of the regulating plate 3 is provided with a water inlet hole 4, which provides a channel for accumulated water to flow in and can meet the daily small water volume drainage needs.

[0027] Among them, a limiting frame 12 is fixedly installed on the inner wall of the well frame 1. The limiting frame 12 can limit the placement position of the well cover 2 to prevent it from shifting inside the well frame 1.

[0028] Among them, the top of the first limiting rod 52 is fixedly installed with a limiting block 53. The limiting block 53 can limit the sliding range of the adjusting plate 3 from the top, and prevent the adjusting plate 3 from detaching from the top of the first limiting rod 52.

[0029] Operating Procedures: Under normal weather conditions, the manhole cover 2 is placed stably within the limiting frame 12 of the manhole frame 1. The limiting frame 12 limits the manhole cover 2, preventing it from shifting within the manhole frame 1. At this time, the adjusting plate 3 is in its initial position and remains fixed under the action of the locking component. Accumulated water mainly flows in slowly through the water inlet 4 on the outer surface of the top of the adjusting plate 3. The reinforcing block 11 on the manhole frame 1 strengthens the connection between the manhole frame and the ground foundation, ensuring the stability of the overall structure.

[0030] When encountering severe weather such as heavy rain or short-term heavy precipitation, and the surface water volume increases sharply, emergency drainage operation is initiated. After locating the manhole cover, the staff or relevant maintenance personnel put their hands into the groove 31 on the outer surface of the top of the adjusting plate 3 and pull the pull plate 35. Under the action of the pull, the spring 33 is compressed, and the telescopic rod 34 retracts and returns to the installation groove 32. The locking plate 36 disengages from the locking groove 21, releasing the locking between the adjusting plate 3 and the manhole cover 2. Subsequently, the adjusting plate 3 slides down along the first limiting rod 52 until it slides onto the limiting plate 5. At this time, the annular groove 6 is opened, forming a large drainage channel. A large amount of water can flow into the manhole quickly through the annular groove 6. Since the adjusting plate 3 only slides down to the limiting plate 5, it is a short-distance adjustment, and the limiting plate 5 supports the adjusting plate 3, preventing the manhole opening from being completely exposed. This effectively avoids the risk of pedestrians or vehicles falling into the manhole. During the water inflow process;

[0031] After the severe weather ends and the surface water is drained, the manhole cover is reset. The worker pulls the adjusting plate 3 upwards, causing it to slide upwards along the first limiting rod 52. During the sliding process, the limiting block 53 at the top of the first limiting rod 52 will limit the sliding range of the adjusting plate 3, preventing the adjusting plate 3 from detaching from the top of the first limiting rod 52. When the adjusting plate 3 slides to the initial position, the pull plate 35 is released, the spring 33 returns to its natural extended state, pushing the telescopic rod 34 to extend outwards. The pull plate 35 moves accordingly, causing the locking plate 36 to re-insert into the locking slot 21, thus locking the adjusting plate 3 and the manhole cover 2 again, and restoring the manhole cover to its normal state.
