The invention discloses a power-off alarm system for a construction site elevator. The power-off alarm system for the construction site elevator comprises an elevator body, sliding rails are slidablyconnected to the two sides of the elevator body, an elevator door is formed in the elevator body, a liquid storage box is fixedly connected to the top of the elevator body, and sliding grooves are formed in the two symmetrical side walls of the liquid storage box; sliding blocks matched with the sliding grooves in size are connected into the sliding grooves in a sliding mode, the top of each sliding block is fixedly connected with a spring, the fixed end of each spring is fixedly connected to the top of the corresponding sliding groove, and the opposite sides of the two sliding blocks are fixedly connected with a film net connected to the inner wall of the liquid storage box in a sealed and sliding mode; and a connecting block is fixedly connected to the center of the film net, a supporting rod is fixedly connected to the connecting block, and the top of the supporting rod penetrates through the liquid storage box and the inner wall of the elevator body in a sealed mode at the same time. The power-off alarm system for the construction site elevator has the advantages that carbon dioxide in the elevator can be absorbed when the elevator is powered off, the automatic alarm function is achieved according to the reaction amount of the carbon dioxide, and accidents are avoided.

    本发明公开了一种工地电梯用断电报警系统,包括电梯本体,所述电梯本体的两侧滑动连接有滑轨,所述电梯本体中开设有电梯门,所述电梯本体的顶部固定连接有储液盒,所述储液盒的两个对称的侧壁开设有滑槽,每个所述滑槽中滑动连接有尺寸大小相配合的滑块,每个所述滑块的顶部固定连接有弹簧并且弹簧的固定端固定连接在滑槽的顶部,两个所述滑块相对的一侧固定连接有密封滑动连接在储液盒内壁的膜网,所述膜网的中心固定连接有连接块,所述连接块固定连接有支杆并且支杆的顶部同时密封贯穿储液盒和电梯本体的内壁。优点在于:可以在电梯断电时吸收电梯内的二氧化碳并根据二氧化碳的反应量实现自动报警的功能,避免出现事故。
