[0002] The manhole cover is used to cover the road or deep well at home to prevent people or objects from falling. Most of the manhole covers are cast iron and generally round. They can be used in green belts, sidewalks, motor vehicle lanes, docks, alleys, etc. Due to the value of steel and the drive of economic interests, it leaves an opportunity for illegal thieves to "steal conveniently". Although administrative authorities at all levels cooperate with the public security to increase the crackdown, due to the wide range of involvement, outdoor placement, and greater difficulty in monitoring, some people took the opportunity to resume their old business, leaving unsafe hidden dangers for pedestrians and vehicles. In order to prevent the manhole covers from being stolen, many manhole cover detection and alarm devices have appeared.

[0003] Some manhole cover detection alarm devices currently on the market: for example, the utility model patent with authorization announcement number CN220691486U discloses a manhole cover detection alarm device, which installs a power storage mechanism on the manhole cover body. The photovoltaic panels in the power storage mechanism cooperate with the charging controller and the battery. In clear weather, the solar energy can be converted into electrical energy and stored in the battery to power the components of the triggering alarm mechanism. Compared with the traditional battery replacement method, it can effectively reduce the number of times road resources are occupied and reduce the impact on road traffic. The triggering alarm mechanism can send an alarm signal when the manhole cover is detached from the base, attracting the attention of pedestrians around and reducing the risk of theft. However, since the device lacks a mechanism for rapid disassembly and assembly, it is not convenient to open the cover body to inspect the electrical connections of the internal components, which needs to be improved.

[0004] Therefore, we have proposed a manhole cover detection device that is easy to repair, so as to solve the problems raised above. Utility Model Content
