Description

Technical Field

[0001] The utility model relates to the technical field of manhole covers, and in particular to an intelligent manhole cover monitoring device. Background Art

[0002] Manhole covers are crucial components of urban infrastructure, ensuring pedestrian safety and maintaining the smooth flow of underground pipelines. Their stability and integrity are crucial. However, frequent loss of manhole covers not only exposes the manhole openings, posing a potential threat to pedestrian safety and increasing the risk of falls, but also damages the covers themselves from impact with debris carried by the water flow, significantly reducing their lifespan. Once a manhole cover is lost, it is often difficult to recover it in a timely manner, posing a significant challenge to urban management.

[0003] Shandong Weimengshi Technology Co., Ltd. has launched an NB smart manhole cover sensor (model: SN-3001-WMYD-NB), designed to provide real-time monitoring of manhole cover status through intelligent means. However, in actual use, the sensor is installed on the steel plate at the bottom of the manhole cover using a clamping fixture. While this installation method may seem convenient, it poses significant risks. Every time a vehicle passes over the manhole cover, the strong vibrations generated will continuously impact the sensor and its fixture. Over time, this can easily cause the sensor to loosen or even fall off, affecting its normal operation.

[0004] Another common fixing method involves drilling holes in the steel plate at the bottom of the manhole cover to secure the sensor with bolts or other fasteners. This directly undermines the original structural integrity of the manhole cover and weakens its load-bearing capacity. Over time, this damage can cause cracks and deformation in the manhole cover, threatening the safety of pedestrians and vehicles. Utility Model Content

[0005] The purpose of the present invention is to solve the problems raised in the above background technology, and then proposes an intelligent manhole cover monitoring device.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] An intelligent manhole cover monitoring device is installed at the bottom of the manhole cover and includes a central mounting assembly with multiple groups of connecting components, which are sleeved on support columns. A manhole cover sensor is fixedly connected to the middle of the central mounting assembly.

[0008] Furthermore, the central mounting assembly includes an upper plate and a lower elastic rubber block. The lower elastic rubber block is provided at the bottom of the upper plate. A central positioning hole for accommodating the installation of the manhole cover sensor is formed in the center of the lower elastic rubber block and the upper plate.

[0009] Furthermore, the fixing plate of the manhole cover sensor is fixedly connected to the upper plate by fastening bolts.

[0010] Furthermore, when the central mounting assembly is fixedly connected to the bottom of the manhole cover through the connecting member, the lower elastic rubber block abuts against the hexagonal support ring and undergoes elastic deformation.

[0011] Furthermore, the connecting component includes a support seat, a locking bolt and a clamp assembly, the support seat is fixedly connected to the side wall of the upper plate, a first rotating shaft is installed on the support seat, a swing plate is rotatably connected to the first rotating shaft, a connecting plate is provided at the end of the swing plate, the clamp assembly is sleeved on the support column, the clamp assembly is connected to a fixed sleeve, a second rotating shaft is provided in the sleeve, a threaded sleeve is rotatably connected to the second rotating shaft, and the locking bolt passes through the connecting plate and is threadedly connected to the threaded sleeve.

[0012] Furthermore, the connecting plate is provided with a through hole for accommodating the locking bolt to pass through.

[0013] Furthermore, a matching plate is rotatably connected to the second rotating shaft, and the two matching plates are fixedly connected to the bottom of the threaded sleeve.

[0014] Furthermore, the clamp assembly includes a left clamp, a right clamp, a clamp bolt and a clamp nut. The left clamp and the right clamp are installed on the fixed sleeve. The left clamp and the right clamp are spliced ​​together by the clamp bolt and the clamp nut to form a clamp ring.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention achieves a stable and elastic connection with the bottom of the manhole cover through the design of a central mounting assembly and connecting member. The central mounting assembly not only effectively fixes the manhole cover sensor, but also adapts to the shape of the hexagonal support ring through the elastic deformation of the lower elastic rubber block, thereby enhancing the stability and adaptability of the installation. The connecting member adopts a structure such as a support seat, a swing plate, a clamp assembly and a locking bolt to achieve a quick and reliable connection with the manhole cover support column, while allowing a certain degree of adjustment to accommodate slight differences in different manhole cover structures. This design not only improves installation efficiency, but also ensures the stability and durability of the monitoring device in long-term use. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1-Figure 5 As shown, a manhole cover 200 is rotatably connected to the manhole cover base 100, wherein a hexagonal support ring 201 is formed at the center of the bottom of the manhole cover, and a plurality of support columns 203 are arranged in a circular array on the manhole cover. Elastic fasteners 202 are welded on the support columns, and the elastic fasteners can be inserted into the grooves of the manhole cover base to prevent the manhole cover from flipping over due to slight vibrations. The above technical features are all existing technologies and have been used for many years and are known to those skilled in the art.

[0024] An intelligent manhole cover monitoring device is installed at the bottom of the manhole cover, including a central mounting component 1, on which are provided multiple groups of connecting components 3, which are sleeved on support columns. A manhole cover sensor 2 is fixedly connected to the middle of the central mounting component, wherein the manhole cover sensor can be purchased from outside, for example, the model SN-3001-WMYD-NB intelligent manhole cover sensor of Shandong Weimengshi Technology Co., Ltd. can be selected.

The lower elastic rubber block is provided at the bottom of the upper plate, and a central positioning hole for accommodating the installation of the manhole cover sensor is formed in the center of the lower elastic rubber block and the upper plate.

[0026] The solution is refined, and the fixing plate 21 of the manhole cover sensor is fixedly connected to the upper plate by fastening bolts 22.

[0027] The solution is refined. When the central mounting assembly is fixedly connected to the bottom of the manhole cover through the connecting member, the lower elastic rubber block rests on the hexagonal support ring and undergoes elastic deformation.

[0028] In at least one embodiment, the connecting member includes a support seat 31, a locking bolt 39 and a clamp assembly 35, the support seat is fixedly connected to the side wall of the upper plate, a first rotating shaft 32 is installed on the support seat, a swing plate 33 is rotatably connected to the first rotating shaft, a connecting plate 34 is provided at the end of the swing plate, the clamp assembly is sleeved on the support column, the clamp assembly is connected to a fixed sleeve 36, a second rotating shaft 37 is provided in the sleeve, a threaded sleeve 38 is rotatably connected to the second rotating shaft, and the locking bolt passes through the connecting plate and is threadedly connected to the threaded sleeve.

[0029] The solution is refined, and the connecting plate is provided with a through hole for accommodating the locking bolt to pass through.

[0030] Furthermore, a matching plate 381 is rotatably connected to the second rotating shaft, and the two matching plates are fixedly connected to the bottom of the threaded sleeve.

[0031] Furthermore, the clamp assembly includes a left clamp 351, a right clamp 352, a clamp bolt 353 and a clamp nut 354. The left clamp and the right clamp are installed on the fixed sleeve.
