Remote control electromagnetic locking piece for box-type substation

Abstract

The invention relates to a remote control electromagnetic locking piece for a box-type substation. The remote control electromagnetic locking piece comprises a lock bolt, a square outer sleeve, a tension spring, a transmission rod and an alternating-current electromagnet. According to the principle of the locking piece, after the alternating-current electromagnet is powered on, electromagnetic attraction is generated to drive the lock bolt to move rightwards, a door board is automatically ejected out under the effect of a compression spring, and the door board of the box-type substation is then opened. After power is off, the lock bolt is reset under the effect of tension of the tension spring. The internally-arranged locking piece is ingenious and reasonable in structural design, and the locking piece is arranged in the box-type substation and is waterproof, dampproof and high in safety performance. The problems that a padlock exposed outdoors is easy to damage and low in safety are solved. Remote power control is adopted, labor cost is saved, work efficiency is improved, and the remote control electromagnetic locking piece can be widely applied and popularized.

Description

technical field [0001] The invention belongs to the technical field of locks, and relates to a built-in lock, in particular to a remote control electromagnetic lock for a box-type substation. Background technique [0002] Box-type substation, also known as prefabricated substation. It is suitable for mines, factories, enterprises, oil and gas fields and wind power stations. It replaces the original civil engineering power distribution room and power distribution station, and becomes a new type of complete power transformation and distribution device. Existing box-type substations are generally installed outdoors, and locks are usually provided for safety reasons. Common locks are divided into padlocks and built-in locks. There are two problems with padlocks: [0003] 1. The padlock lock body is exposed outdoors. When it encounters harsh natural environments such as sun and rain, it is easy to cause damage or cannot be opened. If it is turned on normally, it will cause hug...

AI Technical Summary

Problems solved by technology

[0005] For built-in locks, although the above problems have been solved to a certain extent, there is a problem of inconvenient use, which requires manual opening.

With the increase in the number of box-type substations, each box-type substation needs to be equipped with corresponding keys, and the staff need to hold a large number of keys, which not only increases the workload but is also easy to lose, increases work costs, and affects work efficiency.
