On one hand, when the manhole cover is normally closed, the flexible support device supports the main central part of the cover. Compared to only flexibly supporting the periphery, the manhole cover receives a larger support surface and the supported area is closer to its center of gravity, resulting in better flexible support. On the other hand, when maintenance personnel need to enter the manhole, the cover can be opened first, and then the flexible support device can be removed from the mounting cavity. This prevents the mounting cavity from being occupied by the flexible support device, thus preventing it from obstructing maintenance personnel from entering the manhole and allowing them to pass through the mounting cavity to access the manhole below for work.

[0025] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings.

[0026] Please refer to Figures 1-5 This application provides an anti-settlement manhole cover 200, comprising a manhole base 100, a manhole cover 200, and a flexible support device 300. The manhole base 100 includes a manhole cylinder 110 and a flange edge 120 located around the manhole cylinder 110. The flange edge 120 of the manhole base 100 is directly pressed onto the roadbed. Generally, a groove is provided on the road surface corresponding to the area of ​​the flange edge 120, so that the flange edge 120 is placed in the groove, thereby making the upper side of the flange edge 120 roughly flush with the actual road surface. The flange edge 120 can distribute vehicle loads to the surrounding road surface, thereby preventing local subsidence. The manhole cylinder 110 forms an installation cavity 130. Since the manhole shaft is located below the manhole base 100, the installation cavity 130 is actually the entrance to the manhole shaft. Maintenance personnel must pass through the installation cavity 130 of the manhole base 100 to enter the manhole shaft. The flexible support device 300 is disposed within the mounting cavity 130. The manhole cover 200 is connected to the manhole base 100 and covers the mounting cavity 130. When the manhole cover 200 is closed onto the manhole base 100, the entire manhole cover 200 is positioned above the mounting cavity 130. At this time, the flexible support device 300 contacts the lower side of the manhole cover 200, thereby providing direct flexible support for the manhole cover 200. This not only enhances the shock absorption and noise reduction effect but also improves the effect of preventing subsidence by absorbing vehicle impact energy. In this embodiment, after the manhole base 100 is installed on the road, the area below the manhole base 100 is the manhole passage. External personnel need to pass through the mounting cavity 130 of the manhole base 100 to enter the manhole passage.

[0027] The difference between this embodiment and the prior art is that the inner wall of the well shaft 110 is provided with a base plate 111, the flexible support device 300 includes a bracket 310 and a first support component 320, the first support component 320 is disposed on the bracket 310 and is used to support the well cover 200, the upper side of the base plate 111 is provided with a connecting groove 112, the lower side of the bracket 310 is provided with a connecting buckle 340, the connecting groove 112 and the connecting buckle 340 are detachably connected so that the flexible support device 300 can be removed from the mounting cavity 130. The base plate 111 directly supports the bracket 310. The bracket 310 is placed on the base plate 111, so that the connecting buckle 340 cooperates with the connecting groove 112 to realize the connection and fixation between the base plate 111 and the bracket 310. When maintenance personnel need to enter the well for work, they can first open the well cover 200, and then remove the connecting buckle 340 from the connecting groove 112 to separate the bracket 310 from the base plate 111, thereby realizing the disassembly of the flexible support device 300. This allows the mounting cavity 130 of the well barrel 110 to no longer be occupied by the flexible support device 300, so that maintenance personnel can enter the well below through the mounting cavity 130 of the well barrel 110. Therefore, the anti-settlement manhole cover 200 of this application embodiment, by detachably installing the flexible support device 300 on the manhole base 100, on the one hand, when the manhole cover 200 is normally closed, the flexible support device 300 supports the main part in the middle of the manhole cover 200. Compared with only flexibly supporting the periphery of the manhole cover 200, the manhole cover 200 obtains a larger support surface and the supported area is closer to its own center of gravity, so the flexible support effect of the manhole cover 200 is better. On the other hand, when maintenance personnel need to enter the manhole, the manhole cover 200 can be opened first, and then the flexible support device 300 can be removed from the mounting cavity 130, so that the mounting cavity 130 of the manhole base 100 is no longer occupied by the flexible support device 300, preventing the flexible support device 300 from obstructing the maintenance personnel from entering the manhole, so that the maintenance personnel can enter the manhole below through the mounting cavity 130 to carry out work.

[0028] Please refer to Figure 2 and Figure 5In this embodiment of the application, the connecting groove 112 includes a receiving section 1121 and a locking section 1122 that are laterally connected to each other. The receiving section 1121 has an upward opening 1123, and the locking section 1122 is closed on the upper side. The connecting buckle 340 includes an extension 341 and a side protrusion 342 provided on the side of the extension 341. The receiving section 1121 is used for the connecting buckle 340 to extend into, and the locking section 1122 is used to lock the connecting buckle 340. When installing the flexible support device 300 into the mounting cavity 130 of the well shaft 110, first align the connecting buckle 340 with the connecting groove 112, then place the bracket 310 toward the base plate 111, so that the connecting buckle 340 is inserted into the receiving section 1121 of the connecting groove 112, thereby achieving the mating connection between the connecting buckle 340 and the connecting groove 112. The locking section 1122 of the connecting groove 112 is used to lock the connecting buckle 340, ensuring the installation stability of the bracket 310 on the base plate 111, reducing the shaking of the bracket 310 relative to the base plate 111, thereby further improving the vibration reduction and noise reduction effect.

[0029] In this embodiment, the specific fastening connection method between the connecting groove 112 and the connecting buckle 340 can be that the side protrusion 342 is set as a flexible or elastic structure. During the process of the connecting buckle 340 extending into the receiving section 1121 of the connecting groove 112, the side protrusion 342 deforms to enter the receiving section 1121 due to the large force. After the side protrusion 342 enters the receiving section 1121, it returns to its initial shape and is blocked by the locking section 1122. Specifically, in the first embodiment, the side protrusion 342 is a rubber protrusion that is deformed by compression during entry into or exit from the receiving section 1121, and maintains its normal initial shape when it is located inside the receiving section 1121, and is blocked by the locking section 1122; in the second embodiment, the side protrusion 342 includes a spring and a protruding head. When entering or exiting the receiving section 1121, the protruding head is compressed, thereby compressing the spring, causing the protruding head to retract in a direction away from the locking section 1122. When the side protrusion 342 is located in the receiving section 1121, the spring returns to its original position to push the protruding head into the locking section 1122.

[0030] However, in the above-mentioned fastening connection methods of the connecting groove 112 and the connecting buckle 340, the former has a lower connection firmness, and the latter's connecting buckle 340 has a more complex structure. Furthermore, both methods require a large external force to disassemble the flexible support device 300, which is inconvenient for operation. Therefore, in this embodiment, it is preferable that the lateral width of the connecting buckle 340 is smaller than the lateral width of the receiving section 1121, and that the side protrusion 342 faces the locking section 1122, so that after the connecting buckle 340 enters the receiving section 1121, it moves towards the locking section 1122 to extend the side protrusion 342 into the locking section 1122. In this embodiment, the first step involves inserting the connecting buckle 340 into the receiving section 1121 of the connecting groove 112. The lateral width of the connecting buckle 340 is smaller than the lateral width of the receiving section 1121 to facilitate insertion. After insertion, the side protrusion 342 faces the locking section 1122 of the connecting groove 112. The second step involves applying external force to the bracket 310, causing it to rotate. This rotates the bracket 310, moving the side protrusion 342 towards the locking section 1122, allowing it to enter the locking section 1122 and thus locking the side protrusion 342. The fastening connection structure between the connecting buckle 340 and the connecting groove 112 in this embodiment is relatively simple, and installation and disassembly are effortless. Only the bracket 310 needs to be rotated to allow the side protrusion 342 to enter or leave the locking section 1122 of the connecting groove 112, saving time and effort and facilitating operation.

[0031] Since the flexible support device 300 needs to support the manhole cover 200 and absorb the impact energy of the vehicle to achieve shock absorption and noise reduction of the manhole cover 200, the bracket 310 needs to withstand greater pressure. It is more reliable for the bracket 310 to be directly supported by the base plate 111. Therefore, in this embodiment, it is preferable that the length of the protrusion 341 from the lower side of the bracket 310 is less than the distance between the bottom wall of the receiving section 1121 and the lower side of the bracket 310, so that the base plate 111 directly supports the bracket 310. In this way, after the connecting buckle 340 and the connecting groove 112 are connected, the protrusion 341 does not contact the bottom wall of the receiving section 1121, and the lower side of the bracket 310 directly presses against the upper side of the base plate 111. The base plate 111 reliably supports the bracket 310, avoiding the situation where the bracket 310 cannot be directly supported by the base plate 111 due to the excessive length of the connecting buckle 340, thereby improving the structural stability and improving the shock absorption and noise reduction effect of the flexible support device 300 and the manhole cover 200.

[0032] Referring to the figures, in this embodiment of the application, the substrate 111 is a continuous annular structure, or the substrate 111 includes multiple sub-plates distributed on the inner wall of the well shaft 110, the multiple sub-plates being arranged in a circumferential array around the central axis of the well shaft 110. In the first embodiment, the substrate 111 is a continuous annular structure, which has stronger integrity and can improve its own structural strength, thereby improving the support effect on the flexible support device 300; in the second embodiment, the substrate 111 includes multiple discretely distributed sub-plates, which can save materials. In some embodiments, the substrate 111 is provided with multiple connecting grooves 112, preferably the connecting grooves 112 are also arranged in a circumferential array around the central axis of the well shaft 110, and the connecting buckles 340 on the bracket 310 are correspondingly provided with the connecting grooves 112 one by one.

[0033] Referring to the figure, in this embodiment of the application, the bracket 310 includes a central seat 311 and a plurality of support rods 312. The plurality of support rods 312 are evenly distributed around the central seat 311, and the support rods 312 extend from the central seat 311 to the outer periphery. The first support component 320 is disposed on the central seat 311. On the one hand, the central seat 311 is located at the center of the bracket 310 for the installation of the first support component 320, so that the first support component 320 can support the center of the manhole cover 200, thereby enabling the manhole cover 200 to obtain uniform and sufficient flexible support and improve the shock absorption and noise reduction effect. On the other hand, the support rods 312 are evenly distributed around the central seat 311 and extend outward to support the central seat 311. The space between adjacent support rods 312 is hollow, which can save materials. Moreover, the support rods 312 serve as the gripping part when the operator rotates the bracket 310, making it easy to grip and exert force, making it easier for the operator to rotate the bracket 310, thereby improving the convenience of assembling and disassembling the flexible support device 300.

[0034] In this embodiment, the central seat 311 is specifically a cylindrical cup structure with the opening 1123 facing upwards. It has a cylindrical groove for the installation of the first support component 320. The first support component 320 can be a rubber column inserted into the central seat 311, but its upper end protrudes from the central seat 311 to flexibly support the manhole cover 200 through its own material properties. Furthermore, the lower end of the rubber column can also be connected to a spring, which is set in the central seat 311 to elastically support the rubber column and further improve the shock absorption and noise reduction effect.

[0035] Furthermore, the bracket 310 needs to be connected to the base plate 111 via a connecting buckle 340. If the bracket 310 only includes a central seat 311 and a support rod 312, the connecting buckle 340 is located at the end of the support rod 312 away from the central seat 311 (the end of the support rod 312) to correspond to the connecting groove 112 on the base plate 111. In some improved embodiments, the bracket 310 preferably also includes an outer ring frame 313, which is a ring structure. The ends of the plurality of support rods 312 are all connected to the outer ring frame 313, and the base plate 111 supports the outer ring frame 313. In this embodiment, the bracket 310 contacts the base plate 111 through the outer ring frame 313, and the base plate 111 directly supports the outer ring frame 313. Thus, the connecting buckle 340 is provided on the lower side of the outer ring frame 313. The outer ring frame 313 is a ring structure that connects the ends of multiple discrete support rods 312, thereby improving the structural stability of the support rods 312, thereby improving the overall structural strength of the bracket 310 and enhancing the support effect of the flexible support device 300.

[0036] For further details, please see Figure 3 Preferably, the flexible support device 300 further includes a second support component 330, which is disposed on the upper side of the outer ring frame 313 to support the periphery of the manhole cover 200. Specifically, the second support component 330 can adopt the same structure as the first support component 320, which is a rubber part disposed on the upper side of the outer ring frame 313, or a rubber part with a spring connected to its lower end, to directly and flexibly support the manhole cover 200. This allows the manhole cover 200 to obtain good flexible support in both the central and peripheral areas, further improving the shock absorption and noise reduction effect.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
