[0002] Water conservancy flood control refers to the use of appropriate engineering measures in accordance with local conditions to reduce the damage caused by floods to the natural environment, personal safety and man-made facilities. There are many types of water conservancy flood control devices, such as dams, flood control gates and reservoirs. The more common water conservancy flood control devices in cities are factory flood control devices. When floods occur, the existing factory flood control devices generally drive the waterproof board to rise through electric or hydraulic devices. After the waterproof board is raised, it is attached to the bonding frames set on both sides to block and isolate the flood.

[0003] However, the existing factory flood prevention devices generally have their laminating frames directly fixed on the wall or the ground, and the portion of the waterproof board in contact with the laminating frame is usually exposed to the air. Vehicles and personnel entering the factory are likely to bring various impurities to the waterproof board or the laminating frame, which can easily cause impurities to be caught in the portion of the waterproof board in contact with the laminating frame during flood prevention, and the portion of the waterproof board in contact with the laminating frame is not tightly fitted, which leads to a low airtightness between the waterproof board and the laminating frame and a poor flood prevention effect.
