AI Technical Summary
The existing fences are ineffective in preventing thieves from climbing over them, resulting in poor protection.
A structure including a fence frame, a rotating rod, a barrier plate, gears, toothed plates, and a movable plate is designed. When a person climbs, their weight pulls down the movable plate, which in turn drives the toothed plates and the rotating rod to rotate. The barrier plate tilts to prevent climbing. Combined with the conical and threaded rod design on the barrier plate, it prevents injuries during climbing and carrying.
It effectively prevents people from climbing over the fence, providing better protection and ensuring the safety of workers during handling.
