Problems solved by technology

At the same time, there are also some disadvantages: the flood control baffle is rotated by the buoyancy of the water, and it takes a certain amount of flood water to pass through the equipment before the flood control baffle slowly rises to prevent flooding, and some flood water still invades the room and damages the equipment and decoration in the station; in addition, the current The large-area baffles of some hydrodynamic automatic flood gates are inconsistent with the pavement style of the subway station ground, which affects the overall decoration effect

Abstract

The invention relates to the technical field of subway station flood prevention, in particular to a hydrodynamic automatic lifting anti-flooding system. The system comprises a water collecting well and an intercepting ditch which are both buried under the ground of a subway station, wherein the water collecting well communicates with the intercepting ditch, a buoyancy lifting mechanism is arranged in the water collecting well, the bottom of the buoyancy lifting mechanism floats on the water surface of the water collecting well, and the top of the buoyancy lifting mechanism may pass through the ground to intercept flood. The scheme has the characteristics of being better in flood control effect, attractive in appearance, capable of saving manufacturing cost, simple in structure, high in reliability, easy and convenient to operate and convenient to maintain and use; in a normal state, namely in a daily mode, the buoyancy lifting mechanism sinks into the bottom of the water collecting well under self-weight, and the top end of the buoyancy lifting mechanism is just hidden in the water collecting well at the moment; and in the flood control mode, the buoyancy lifting mechanism ascends and extends out of the ground by means of water buoyancy to intercept the flood, the flood is blocked outside and prevented from flowing into the subway station, and the flood control requirement of the subway station is met.

Description

technical field [0001] The invention relates to the technical field of flood control for subway stations, in particular to a hydrodynamic automatic lifting and flooding control system. Background technique [0002] Since the subway station is set up underground, most of the equipment in the station will be damaged once it suffers from floods, causing heavy economic losses. Therefore, flood control is an important aspect of subway station design considerations. The current water-powered fully automatic flood control gates have begun to be piloted for flood control in the subway. Compared with the traditional flood control method of manually installing water barriers, it has the advantages of no need for personnel on duty, timely flood control, and automatic flood control. At the same time, there are also some disadvantages: the flood control baffle is rotated by the buoyancy of the water, and it takes a certain amount of flood water to pass through the equipment before the fl...
