Mining explosion-proof lighting device

Abstract

The invention discloses a mining explosion-proof lighting device. The mining explosion-proof lighting device comprises a lamp shade and a connector, wherein the lamp shade is fixedly connected with the connector; a light-emitting mechanism is arranged below the connector; a focusing and amplifying mechanism is arranged around the light-emitting mechanism and is connected with the light-emitting mechanism through a pipeline; a circulating mechanism is arranged on one side of the focusing and amplifying mechanism; a control mechanism is arranged on one side of the circulating mechanism; the inner wall of the lamp shade is made of a light-reflecting material; the light-emitting mechanism comprises a lamp wick pipeline; neon and pure water are arranged in the lamp wick pipeline; the focusing and amplifying mechanism comprises a convex lens I; the convex lens I is hollow and is connected with the lamp wick pipeline through a pipeline; a convex lens II is arranged below the convex lens I; aflexible film is arranged on the surface of the convex lens II; and a focal length adjusting cavity is formed between the flexible film and the convex lens II. The mining explosion-proof lighting device has the characteristics of high practicability and capability of reducing the temperature of a using environment.

Description

technical field [0001] The invention relates to the technical field of explosion-proof lighting for mines, in particular to an explosion-proof lighting device for mines. Background technique [0002] Explosion-proof lamps for mines are explosion-proof lamps suitable for coal mines with gas or (and) coal dust explosion hazards, suitable for dangerous environments in the coal mine industry with explosive mixture gases such as methane and coal dust; mine explosion-proof lamps developed by Tongming Electric are suitable Fixed floodlighting in coal mine tunnels and chambers; suitable for fixed floodlighting in coal mines, substations, parking lots, pump rooms and other places; [0003] Existing mine explosion-proof lamps use neon lamps as the light source, and the working environment inside the mine is relatively high temperature, and there are explosive mixture gases such as methane and coal dust, so it is easy to explode, so it can be added to the neon lamp Insulating liquid, ...

AI Technical Summary

Problems solved by technology

[0003] Existing mine explosion-proof lamps use neon lamps as light sources, and the working environment inside the mine is relatively high temperature, and there are explosive mixture gases such as methane and coal dust, so explosions are prone to occur, and neon lamps can be added Insulating liquid, the insulating liquid can not only reduce the heat generated when the neon lamp is used, but the insulating liquid can also use its own transparent nature to make it into a convex lens, which can focus and magnify the light, while the existing mine lighting devices cannot To reduce the temperature of the environment in which it is used, it is necessary to design a mining explosion-proof lighting device that is practical and can reduce the temperature of the environment in which it is used.
