The invention discloses an anti-falling device for a municipal inspection well. The device comprises an anti-falling device main body, a well lid, a worm, and a driven shaft; the well lid is installed at the top of the anti-falling device main body; a servo motor is arranged in the anti-falling device main body; the top of the servo motor is connected with the worm; the surface of the worm is connected with a ratchet wheel through a leather wheel set; and the inner wall of the ratchet wheel makes contact with the tops of ratchets. According to the anti-falling device for the municipal inspection well, warning columns are installed around the well lid, and when the well lid is lost, a linkage rod can pull a fixing bolt through a tension rope under the elastic action of a telescopic spring, so that the warning columns ascend under the elastic action of a reset spring; and the warning columns can be erected on the periphery of the inspection well, so that pedestrians can be warned at the first time after the well lid is lost, and the phenomenon that casualties are caused due to the fact that people fall into the inspection well is avoided.
本发明公开了一种市政检查井用防坠入装置，包括防坠入装置主体、井盖、蜗杆和从动轴，所述防坠入装置主体的顶部安装有井盖，且防坠入装置主体的内部设置有伺服电机，并且伺服电机的顶部与蜗杆相连接，所述蜗杆的表面通过皮轮组与棘轮相连接，且棘轮的内壁与棘齿的顶部相接触。该市政检查井用防坠入装置，在井盖的周围安装有警示柱，当井盖出现遗失时，使得联动杆会在伸缩弹簧的弹性作用下通过拉力绳对固定栓进行拉动工作，从而使得警示柱在复位弹簧的弹性作用下进行上升运动，有利于警示柱竖立在检查井的四周，方便在井盖遗失后的第一时间能够警示行人，避免人员掉落到检查井的内部，从而造成人员的伤亡的现象。
