AI Technical Summary
The existing rigid interlocking isolation mechanism lacks mechanical interlocking between the spiral spring energy storage device and the grounding device, which leads to the operation sequence relying on manual judgment, posing a risk of misoperation. Furthermore, the grounding operation shaft has no mechanical limit, making it prone to over-rotation and mechanical damage.
A five-proof forced hard interlock isolation mechanism was designed. By setting an interlocking sliding plate between the spiral spring energy storage device and the grounding device, the sliding plate anti-rotation block and the anti-rotation notch form a forced lock to ensure that the energy storage/grounding states are mutually exclusive. The stability and impact resistance are improved by reinforcing plates and rotation limit seats. The grounding operation shaft adopts a regular hexagonal and serrated cross section to prevent malfunction.
It achieves higher protection and safety, ensures the stability and consistency of the operation sequence, prevents misoperation and excessive rotation, and improves the safety and reliability of the equipment.
