Technical field:

The utility model relates to a special explosion-proof lamp for coal mine mining, which belongs to the technical field of coal mine appliances.

Background technique:

Explosion-proof lamps refer to lamps that are used in hazardous places where flammable gases and dust exist, and can prevent arcs, sparks and high temperatures that may be generated inside the lamp from igniting flammable gases and dust in the surrounding environment, thereby meeting explosion-proof requirements. Also known as explosion-proof lamps, explosion-proof lighting. Different flammable gas mixture environments have different requirements for explosion-proof grades and explosion-proof forms of explosion-proof lamps.

With the rapid development of industries such as petroleum, chemical industry, and mining, lighting fixtures are used more and more widely in production, storage, and rescue, and there are more and more varieties. How to prevent the accidental explosion of lighting fixtures in explosive gas hazardous places has become a very important issue. Since lighting fixtures inevitably generate electric sparks or form hot surfaces during work, once they meet the explosive gas mixture at the production or rescue site, it will cause an explosion accident, directly endangering the lives of citizens and the safety of national property. Therefore, as the most widely used lighting fixture, its explosion-proof technology has already attracted widespread attention and great attention. Aluminum alloy shell, surface sprayed; dual-purpose for lighting and emergency; built-in maintenance-free nickel-cadmium battery pack, automatic charging under normal power supply, emergency lights are automatically lit when power is off in an accident or power failure; steel pipe wiring; emergency special lights are normal The lighting and emergency lighting are independent; the lighting emergency dual-purpose lamp, normal lighting and emergency lighting share a lamp body, and the light source is independent.

However, the existing explosion-proof lamps are poor in airtightness when in use, causing them to easily cause harm during use, and when in use, two separate light sources are used, which wastes space and has low efficiency.
