Hydrodynamic automatic lifting anti-flooding system
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.
本发明涉及地铁车站防洪技术领域，为一种水动力自动升降防淹系统，包括均埋设于地铁车站地下的集水井及截水沟，所述集水井与所述截水沟连通，所述集水井内设有浮力升降机构，所述浮力升降机构的底部漂浮于集水井的水面上，顶部可穿过地面以拦截洪水。该方案具有防洪效果更优、外形美观、节省造价作用、同时具有构造简洁、可靠性强、操作简便、维护使用方便的特点。正常状态下即日常模式中时，浮力升降机构在自重下沉入集水井底部，此时浮力升降机构顶端刚好藏于集水井中。防洪模式下，浮力升降机构依靠水浮力上升伸出地面可拦截洪水，将洪水挡在外侧，防止洪水流入到地铁车站里面，满足地铁车站防洪要求。
