[0002] During the construction of water conservancy projects, in order to prevent non-construction personnel from mistakenly entering the construction site, it is necessary to install protective fences outside the construction site.

[0003] After searching, the patent with announcement number CN112031525B discloses a safety protection structure for water conservancy construction, which drives the connecting block to move downward on the connecting rod through the movable block. The rotational connection between the connecting block and the movable plate and the rotational connection between the movable plate and the grounding plate can enable the movable plate to rotate, so that the device can be quickly deployed. When the movable block moves to the position of the connecting rod close to the support rod, the movable block is connected to the connecting rod through a threaded connection, which can fix the movable plate well. The device can be transported more flexibly before being put into use, and can be quickly deployed and stably placed on the ground after being put into use. It is simple to operate and has good stability.

[0004] In actual use, although the above-mentioned solution can fold and store or unfold the docking floor and the movable plate to make the connecting frame easier to store and transport, the driving structure of the docking floor and the movable plate is too complicated, and each two connecting frames can only be used to support one protective net, that is, two connecting frames are required between every two adjacent protective nets, which greatly increases the number of connecting frames used and increases the cost of using the device, which needs to be improved.
