Buoyancy device for preventing rainwater from flowing backwards at subway entrance
The invention relates to the technical field of subway entrance anti-backflow equipment, in particular to a buoyancy device for preventing rainwater from flowing backwards at a subway entrance. The buoyancy device comprises a waterproof baffle, a plastic box body and a buoyancy chamber for storing rainwater. And the buoyancy chamber is embedded below the ground of the entrance/exit of the subway station. And a space for accommodating the waterproof baffle plate and the plastic box body is formed in the buoyancy chamber. The top of the buoyancy chamber is provided with a lifting channel for the waterproof baffle to stretch out. A drainage ditch is arranged on one side of the lifting channel. And the drainage ditch is connected with the buoyancy chamber. A clamping groove is formed in the inner wall of the buoyancy cavity. The bottom of the buoyancy chamber is connected with a drainage pipe. According to the buoyancy device, the plastic box body and the waterproof baffle plate float upwards by fully utilizing buoyancy generated by water filling of the buoyancy chamber due to backflow of rainwater, so that the problem that water blocking needs to be solved in subway entrances and exits and the like under the influence of heavy rainfall weather is solved, water drainage facilities at the entrances and exits of the subway stations are optimized, rainwater is prevented from flowing back into the subway stations, and the service life of the subway stations is prolonged. And the waterproof effect is improved.
本发明涉及地铁口防倒灌设备技术领域，具体涉及一种地铁口防雨水倒灌的浮力装置。该浮力装置包括防水挡板、塑料箱体和供雨水存储的浮力腔室。浮力腔室嵌入在地铁站出入口的地面下方。浮力腔室的内部具有容纳防水挡板和塑料箱体的空间。浮力腔室的顶部设置有供防水挡板伸出的升降通道。升降通道的一侧设置有排水沟。排水沟与浮力腔室相连。浮力腔室的内壁上设置有卡槽。浮力腔室的底部连接有排水管。该浮力装置充分利用了雨水倒灌使浮力腔室充水产生的浮力，使塑料箱体和防水挡板向上浮起，解决了在强降雨天气影响下，地铁出入口等地需要解决挡水的问题，优化了地铁站出入口的疏水排水设施，避免了雨水倒灌入地铁站内，提高了防水效果。
