Airbag 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 subway entrance rainwater anti-backflow air bag device which comprises a step part arranged on the front side of a subway entrance, the step part is internally provided with a water storage tank, an air guide pipe, a concave cavity, a jacking gear bag and a baffle assembly, and the water storage tank is internally provided with a bag moving assembly. The bag moving assembly comprises a floating plate, a pressure storage bag and a metering plate which are arranged from top to bottom, the lower portion of the side wall of the pressure storage bag communicates with the bottom of an inner cavity of a jacking gear bag arranged in the concave cavity through the air guide pipe, and the top of the outer wall of the jacking gear bag makes contact with the bottom of the baffle assembly. According to the water retaining device, in rainy days, the water amount in the water storage tank is gradually increased, the floating plate in the water storage tank moves downwards under the action of rainwater, after the floating plate moves downwards, the pressure storage bag is pressed, gas in the pressure storage bag is blown into the jacking retaining bag, after the jacking retaining bag is blown, the balance weight baffle is jacked up till a certain volume or height is reached, and then the water retaining function is achieved.
本发明涉及地铁口防倒灌设备技术领域，具体为一种地铁口防雨水倒灌的气囊装置，包括设置于地铁口前侧的阶梯部，所述阶梯部的内部设有蓄水池、导气管、凹腔、顶升档囊和挡板组件，所述蓄水池内设有囊动组件，所述囊动组件包括由上至下设置的浮板、储压囊和计量板，所述储压囊的侧壁下方通过所述导气管与设置于所述凹腔内的顶升档囊的内腔底部连通，所述顶升档囊的外壁顶部与所述挡板组件的底部接触。本发明中，当发生雨水天气时，蓄水池中的水量逐渐增加，蓄水池中的浮板在雨水的作用下下移，浮板下移后，储压囊受压，储压囊的气体被鼓入顶升挡囊，顶升挡囊被鼓气后，从而将配重挡板顶起，直至到达一定体积或高度，继而实现挡水功能。
