Technical Field

[0001] The utility model relates to a protection net, in particular to a safety protection net for a cable well cover, belonging to the technical field of cable well ancillary facilities. Background Art

[0002] At present, cities are developing rapidly, and many cables for power transmission are buried in underground cable wells. On the one hand, the cable well provides access points for cables, which is convenient for maintenance personnel to carry out maintenance and inspection work; on the other hand, the wiring and markings in the well can help personnel quickly locate faulty cables and repair or replace them in time, which greatly improves the efficiency of maintenance and reduces maintenance time and cost. The cable well is an underground inspection well that plays a role in the construction of the cable burying project and the installation or maintenance after the completion of the project. However, the well covers are often stolen. After the well cover is lost, the open wellhead will bring great danger to pedestrians.

[0003] The existing cable manhole cover protection nets are all circular in shape, which can only be used for manholes with smaller areas, and cannot completely cover large square manholes such as cable manholes. Moreover, cable manholes of different specifications require different types of protection nets. In addition, there is a large gap between the protection net and the manhole wall. When pedestrians accidentally step on the air and fall into the cable manhole, there is a great possibility that they will fall into the manhole through the gap, thereby causing the protection net to lose its protective effect. Utility Model Content
