Description

Technical Field

[0001] The utility model relates to the technical field of cable trenches, and specifically relates to a cable trench cover plate with a compression-resistant structure. Background Technique

[0002] A cable trench is an underground pipeline used for laying and replacing power or telecommunications cable facilities. A plurality of cable brackets are installed in the cable trench, and cables can be arranged in layers to make the cable laying more regular. The cable trench is closed by a trench cover plate above. When maintenance is required, the trench cover plate can be lifted to facilitate workers to enter the cable trench;

[0003] The utility model with the publication number of CN220042946U discloses a cable trench cover plate with a compression-resistant structure, which includes a fixed seat. A cover plate is arranged inside the fixed seat. A disassembly groove is opened at the top of the cover plate. A connecting seat is arranged below the cover plate. A base is arranged below the connecting seat. A spring piece is arranged above the base. A sliding rod is arranged below the spring piece. A connecting plate is arranged outside the sliding rod. An inner groove is opened inside the base. A limiting block is arranged inside the inner groove. A vertical rod is arranged above the limiting block;

[0004] In the above technical solution, by setting the spring piece, when the cover plate is squeezed, the spring piece is squeezed and extends to the left and right sides. The connecting plate slides on the sliding rod, and the pressure can be buffered. At the same time of being squeezed, the vertical rod will move inside the base, and the spring will be squeezed to buffer the pressure again for compression resistance. It is not easy to press the cover plate deformed, improving the compression resistance ability and reducing the occurrence of potential safety hazards. However, the upper surface of the cover plate is connected to the ground, and the smooth cover plate may cause people to fall. In rainy weather, it cannot completely ensure that water will not penetrate below the cover plate. During the long-term use of the cable, it is impossible to completely avoid the occurrence of explosion. When an explosion occurs, it cannot reduce the threat to the outside world. When the cable leaks electricity, it cannot be insulated and may conduct electricity. The cover plate is stepped on by people and vehicles for a long time, and the compression resistance performance cannot be guaranteed. When viewing the internal cable situation, the cover plate needs to be opened. The cover plate is too heavy and inconvenient to move, not convenient and fast. It is impossible to directly and accurately splice between multiple cover plates. Content of the Utility Model
