Anti-flooding device and anti-flooding system of building entrance

Abstract

The invention relates to the technical field of building engineering and municipal engineering, and provides an anti-flooding device. The anti-flooding device comprises a water stop plate used for stopping flood. The anti-flooding device further comprises a water trough allowing the flood to flow in, a flotage body capable of floating up under the flotage action of the flood and a constraint assembly used for constraining the flotage body. The flotage body is arranged in the water trough, and the water stop plate is mounted on the flotage body. The invention further provides an anti-flooding system of a building entrance. The anti-flooding system comprises a platform arranged at the building entrance, and further comprises the above anti-flooding device. The water trough is formed below the platform, and the water stop plate floating up due to the flood in the water trough blocks the building entrance. The water stop plate floats up through the flotage action of the flood is used for stopping the flood, the structure is simple, implementation is easy, and reliability is extremely high; manpower does not need to be wasted for guard, no space needs to be occupied, and users do not need to worry about the situation that flood prevention equipment cannot be started after power off.

Description

technical field [0001] The invention relates to the technical fields of construction engineering and municipal engineering, in particular to an anti-flooding device and a building entrance anti-flooding system. Background technique [0002] The commonly used entrance and exit flood prevention design in current projects is mainly to place flood control sandbags near the entrance and exit. When the rainstorm comes and there is water backflow, the relevant personnel will pile up the sandbags to realize the flood prevention function. This method mainly has the following disadvantages: 1. Design a special storage room or stacking point for flood control materials, which is not beautiful and takes up a lot of space; 2. Due to the lack of automatic intervention function, people need to be on duty during the flood season, which consumes human resources; 4. After the flood control is over, the site needs to be cleaned; 5. In some places, tongue-and-groove panels are used to prevent f...
