An explosion-proof electric switch

Abstract

The invention discloses an explosion-proof electric switch, which comprises an observation window, a baffle plate one, a box body one, a tube one, a tube two, a tube three and a chassis; The switch opening and closing mode of pedal mode, on the one hand, enriches the connection mode of the line and the working mode of the switch, on the other hand, through the setting of different heights, the staff can operate the switch while observing. verb: move. The invention is equipped with an observation window with an adjustable inclination angle and a baffle plate with a large radian. When violent explosions and splashes occur on the construction site, the incident angle between the impacting object and the shielding object can be expanded to the greatest extent. The purpose is to protect both the safety of personnel and the safety of equipment.

Description

technical field [0001] The invention relates to the technical field of coal mine related equipment, in particular to an explosion-proof electric switch. Background technique [0002] With the rapid development of the national economy and the continuous improvement of people's living standards, people's demand for energy is increasing day by day. my country itself is a country rich in coal resources. Not only the quality of coal resources is better, but also the distribution is wide. Therefore, thermal power generation The method has become the main force in the development process of our country at this stage. On the one hand, it is because of its high cost performance, and on the other hand, it is because the level of coal mining has been greatly developed. [0003] Safety issues are a top priority in the coal mining industry. Among them, the operation scenarios of coal mining are mostly in a closed or underground environment. At the same time, it has extremely high require...

Problems solved by technology

In addition, due to the long-term sealing of the working scene, a large amount of dust and even water vapor are unevenly dispersed in the working scene, especially in the process of coal mining operations, it is generally necessary to connect a large external current, and the breakdown will occur instantly when the corresponding switch is connected. The voltage will generate electric sparks. If it comes into contact with a large amount of dust or water vapor, it will cause a short circuit or even an accident of the switch explosion.

[0004] At present, the corresponding switch equipment still has the following problems: (1) Most equipment switches only use a single mode, such as a single knob type. On the one hand, it is not conducive to the staff to observe and operate in different scenarios. On the other hand, it may not be able to react quickly when there is an emergency; (2) There are basically no corresponding observation windows and protective baffles in the current equipment, and it is simply relying on the distance between the construction site and the operation site. It is extremely unreliable in terms of safety; (3) Most of the existing switch equipment is installed in a fixed form, which is extremely inconvenient to move
