AI Technical Summary
During the hoisting and lowering of the cable car inside the wind turbine tower, tools or parts may fall and pose a danger to workers on the ground floor. There is a lack of effective protective measures in the existing technology.
A device for preventing falling objects from a wind turbine tower platform was designed. The device uses a grating sensor to monitor the falling of foreign objects, and a speed controller to determine whether the moving cable of the cable car or the falling of foreign objects is the cause. The device also controls the door assembly to automatically close the hoisting hole to prevent foreign objects from falling.
This effectively prevents tools or parts from falling to the bottom of the tower during the hoisting process of the cable car, thus protecting the safety of the workers at the bottom.
