Ergonomic ground warning device for barrier-free high-voltage electrical equipment

Abstract

An ergonomic, barrier-free ground warning device for high-voltage electrical equipment includes a trapezoidal warning box with a sliding mesh panel inside. The top surface has a hinged cover that can be opened and closed. The front and rear ends have slots for cables to pass through, and the bottom surface has double-sided adhesive for fixation. Multiple warning boxes are joined end-to-end using a snap-fit ​​device. Reflective strips are located on both sides of the outer wall of the warning box, and the bottom surface has a ramp and a water channel. The mesh panel is threadedly connected to a screw, the end of which is movably connected to a rotating base on the ramp. Rotating the screw causes the mesh panel to slide up and down along the inner wall groove. This device, through its trapezoidal structure and ergonomic design, enhances the warning effect and reduces the risk of tripping, integrates cable storage, and is suitable for safety protection around high-voltage electrical equipment.
