Technical Field
[0001] The present application relates to a feeder switch, and in particular to an anti-accidental-touch explosion-proof feeder switch for use in mines. Background Art
[0002] The mine flameproof feeder switch is a kind of explosion-proof electrical equipment designed for explosive environments such as mines. Its background mainly stems from the urgent need for safe power supply in industries such as mines, coal mines, metal mines, chemicals, and oil fields. The working environment of these industries is often accompanied by flammable and explosive gases or dust. Therefore, special explosion-proof electrical equipment is needed to ensure the safety of personnel and equipment. The mine flameproof feeder switch is designed to meet this demand. It can not only control the on and off of the circuit and ensure the normal operation of electrical equipment, but also effectively avoid dangerous situations such as fire or explosion caused by electrical equipment.
[0003] In the related technology, the mine flameproof switch is a key device for safe power supply in the mine. Its design includes the shell, internal electrical components and shell cover. The outer surface of the shell cover is not only equipped with a display screen for displaying information, but also equipped with a control area, integrating the start-stop button and the adjustment button. The start-stop button is responsible for controlling the start and stop of the equipment, while the adjustment button is used for the setting of the protector, such as the display and modification of parameters.
[0004] However, the current design has a significant problem: due to the dim environment in the mine and the fact that the buttons for the two functions are located in the same control area, workers often find it difficult to quickly distinguish them during operation. It is easy for them to accidentally press the start / stop button when checking or modifying parameters, causing the equipment to shut down unexpectedly. This not only affects work efficiency, but may also pose a safety hazard, and there is room for improvement. Utility Model Content
[0005] The purpose of this application is to provide an anti-accidental-touch explosion-proof feeder switch for mining, so as to solve the problem that the start-stop switch is easily accidentally touched in a dim environment in the above-mentioned related technology, which not only affects work efficiency but also may bring potential safety hazards.
