Automatic ejection type inspection well mouth warning device
The invention discloses an automatic ejection type inspection well mouth warning device. The device comprises an annular inspection well base and a well lid matched with the inspection well base; annular air storage cavities are formed in the inspection well base; two operation grooves are formed in the inner side wall of the inspection well base; air injection cylinders are installed in the operation grooves; the output ends of the air injection cylinders communicate with the interiors of the air storage cavities and limit airflow to flow into the air storage cavities in a one-way mode; and two operating rods capable of moving up and down are installed on the inner wall of the inspection well base. A vehicle runs through the surface of the well lid to deform the well lid; due to the fact that the deformation generated at the circle center of the well lid is relatively large, the instantaneous micro-concave deformation phenomenon can be presented, levers can be driven to rotate, the levers push the operating rods to move downwards, the air injection cylinders are driven to work, and the airflow is injected into the air storage cavities through multiple times of movement; and after the well lid is stolen by a lawbreaker, the operating rods move upwards under the action of first springs to push shifting valves, compressed air in the air storage cavities enters strip-shaped air bags, and the strip-shaped air bags are inflated and expanded and are matched with fluorescent strips on the surfaces to warn passing vehicles.
本发明公开了一种自动顶出式窨井口警示装置，包括环形的窨井座和与其适配的井盖，窨井座的内部设有环形的储气腔，窨井座的内侧壁开设有两个操作槽，操作槽的内部安装有注气筒，注气筒的输出端与储气腔的内部连通且限制气流单向流入储气腔，窨井座内壁上安安装有两个可上下活动的操作杆，利用汽车行驶过井盖表面，对其产生形变，由于井盖圆心处产生的形变较大，会呈现瞬时微凹的型变现象，会驱动杠杆转动，杠杆推动操作杆下移，带动注气筒工作，多次运动向储气腔内部注入气流，当井盖被不法分子偷窃后，操作杆在第一弹簧的作用下上移，推动拨动阀，使储气腔内的压缩空气进入条形气囊，条形气囊充气扩张配合表面的荧光条对来往的行车进行警示。
