Description

Technical Field

[0001] The present invention relates to the technical field of screen cabinet door lock status detection, and in particular to a screen cabinet door lock status detection and prompting device. Background Art

[0002] As the name implies, the cabinet door lock is the lock used on the distribution cabinet, which is divided into small distribution cabinet locks; large distribution cabinet locks and outdoor distribution cabinet dustproof locks, etc. Small distribution cabinets do not have high requirements for the safety performance of the lock, and the operation of the lock does not need to be too complicated. It is mainly used to prevent the power supply equipment from being exposed. It is convenient to unlock in case of emergency. A flat single-point lock can be used, and the cabinet door can be opened by flipping up the handle. Large distribution cabinets have higher requirements for the safety performance of the lock. Two-point and three-point locks can be used to lock the cabinet door and add a padlock, which not only achieves the purpose of safety, but also has good controllability. It is also convenient to unlock in case of emergency. Outdoor distribution cabinets have higher requirements for the safety performance of the lock, and have waterproof and dustproof requirements. In addition to using two-point and three-point locks to lock the cabinet door, multiple rubber ring structures are used for waterproofing, and magnetic protective covers are used to achieve the purpose of dustproofing. There are many types of equipment cabinets in substations, such as relay protection panels, mechanism boxes, control cabinets, terminal boxes, etc. There are more than 200 indoor and outdoor cabinets in each voltage level substation. Due to work needs, the cabinets will be opened for inspection and maintenance. After the work is completed, the cabinet doors may not be locked in time, causing the maintenance personnel to mistakenly enter the cabinet to work next time, which violates the "preventing accidental entry into the live interval" of the five electrical protections and causes man-made accidents. At the same time, manual locking of cabinet doors at all stations also has the current situation of frequent tasks, heavy workload, missed locks and low efficiency. When the screen cabinet door lock status detection and prompt device is in use, the status of the screen cabinet door lock cannot be detected in time, resulting in the screen cabinet door lock being easily unlocked, causing damage to the electronic components in the distribution cabinet. At the same time, when the screen cabinet door lock status detection and prompt device is in use, it cannot prepare for the locking between the cabinet door and the distribution cabinet, resulting in inconvenience in connecting the cabinet door and the distribution cabinet when the screen cabinet door lock is damaged. Summary of the invention

[0003] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a device for detecting and prompting the state of a screen cabinet door lock. When the screen cabinet door lock is opened, the screen cabinet door lock can pop out from the inside of the mounting seat and fit into the fitting seat, so that the screen cabinet door lock can use the fitting seat to drive the first fixed plate to squeeze the second spring. When the second spring is affected by the squeezing of the screen cabinet door lock, the pressure sensor can detect the squeezing force exerted on the fitting seat. When the screen cabinet door lock is embedded into the inside of the fitting seat and pushes the fitting seat to pressurize the pressure sensor, the movable plate can pull the first spring forward and swing due to the squeezing of the fitting seat. The swing of the movable plate can drive the baffle plate and the distance measuring sensor to move together. The distance between the movable plate and the cabinet door can be detected through the movement of the distance measuring sensor, so that the distance measuring sensor and the pressure sensor can respectively transmit signals to the alarm, so that the alarm can make a sound to prompt the staff, which is convenient for the staff to make timely The cabinet door lock is locked. When the cabinet door is combined with the distribution cabinet, the cabinet door can drive the first preparatory lock connecting plate to move, so that the first preparatory lock connecting plate can be adsorbed on the surface of the second preparatory lock connecting plate due to the attraction of the magnet to fix the first preparatory lock connecting plate. The two groups of metal plates are pulled upward or downward respectively, so that the second cross plate can be used to pull the third spring. The elasticity of the third spring can be used to form a pulling force between the second cross plate and the first cross plate. The metal plate is pulled to drive the engaging seat to move, and the engaging seat is engaged with the interior of the second preparatory lock connecting plate. When the engaging seat is engaged with the interior of the second preparatory lock connecting plate, the rubber pad and the rubber rod can fit together to produce friction, so that it can improve the engaging effect between the engaging seat and the second preparatory lock connecting plate. In combination with the cabinet door lock, it can improve the connection effect between the cabinet door and the distribution cabinet, etc., and solves the problems of cabinet door lock status detection and inconvenience in using spare locks.
