AI Technical Summary

Technical Problem

Traditional power plant equipment maintenance and isolation methods cannot effectively prevent unauthorized personnel from entering, cannot record and track lock and switch operations, and are slow to unlock in emergency situations, affecting emergency response.

Method used

An unlocking mechanism was designed, including a main body component and a locking component. The mechanism utilizes a motor-driven cam to engage a push rod and a locking element to achieve rapid unlocking. Simultaneously, the lock can be remotely controlled via a Bluetooth connection between a mobile app and the key.

Benefits of technology

Abstract

This utility model relates to the field of electronic lock technology, specifically an unlocking mechanism and a passive intelligent lock for power plant equipment maintenance and isolation. It includes a lock body, a lock rod movably disposed inside the lock body, and a battery disposed inside the lock body; an engaging assembly including a drive component disposed inside the lock body, a lifting component movably disposed on the outer wall of the drive component, and a locking component movably disposed on the outer wall of the lifting component. This utility model, by setting up the engaging assembly, enables a motor to drive a cam to rotate, causing the lifting rod to descend under the action of a first elastic component, and further contraction of a second elastic component to disengage the protrusion from the groove, thus completing the unlocking action and enabling rapid release in emergency situations. Furthermore, it achieves remote control of the lock via a Bluetooth connection between a mobile app and the key, effectively preventing unauthorized intrusion, enhancing security, and allowing for rapid unlocking in emergency situations, improving emergency response efficiency.
