The second rod body 32 is arranged in each assembly hole 21, one end of each second rod body 32 is connected with the corresponding first rod body 31, and the other end is connected with the corresponding third rod body 33.

[0050] Specifically, the middle part of the cover plate body 1 is raised, so that the cover plate is more conspicuous on the ground, and can be easily found even if it is partially covered by a carpet or other objects. This is crucial for quickly finding and opening the cover plate in an emergency. The design of the slope surface 11 allows the raised part to transition smoothly and does not cause obstacles to the normal walking of pedestrians, reducing the risk of tripping and ensuring the safety of pedestrians. Specifically, the cover plate body 1 with slope surfaces 11 on three adjacent sides is used, or the cover plate body 1 with slope surfaces 11 on four adjacent sides is used, mainly referring to the size of the reserved well 5 wellhead that the cover plate body 1 needs to cover. If the size of the wellhead of the reserved well 5 is large, two cover plate bodies 1 need to be used to cover it.
