AI Technical Summary
The interlocking design between the existing switchgear's valve mechanism and the handcart poses a safety hazard. Maintenance personnel may accidentally open the valve and come into contact with live static contacts, leading to a safety accident.
Design a locking safety device that includes a valve slide rail, a limit mechanism, a linkage mechanism, and a transmission mechanism. The limit mechanism controls the opening and closing of the valve, ensuring that the valve automatically opens when the handcart is connected to a live stationary contact, and preventing the valve from being opened arbitrarily when there is no handcart. A sealing ring is used to improve the sealing performance.
It effectively prevents maintenance personnel from accidentally touching live stationary contacts, reduces safety hazards, and improves the sealing between the valve and the stationary contact, preventing dust from entering and enhancing safety and reliability.
