Abstract
The utility model discloses an explosion-proof display for mining and belongs to displays. The display is provided with a box body, a liquid crystal display screen, a display circuit and a video screen signal conversion module, wherein the liquid crystal display screen is mounted on the box body, the display circuit and the video screen signal conversion module are mounted in the box body. The box body is an explosion-proof box body made of steel plates and provided with an explosion-proof cavity inside. The front side of the box body is provided with a front door, an observation window is mounted on the front door and arranged outside the liquid crystal display screen, and a loudspeaker is mounted on the lateral side of the box body. The explosion-proof display for mining has the advantages that an isolation module is connected with an internal power source circuit, and the explosion-proof display for mining has explosion-proof function and particularly applicable to use in the environment having combustible and explosive gas.
Description
Technical field
The utility model relates to display, specifically is a kind of mine explosion-suppression escope, is specially adapted in the inflammable and explosive environment.
Background technology
Present display casing mostly is to form with plastic production, does not possess explosion prevention function, and internal circuit is easy to generate spark, and some place has the danger of methane, coal-dust explosion under the coal mine, so do not suit in such environment, to use.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the utility model provides a kind of mine explosion-suppression escope, has the flame proof function, is applicable under the various adverse circumstances, particularly coal mine to have in the environment of flammable explosive gas with plant area of enterprise of chemical oil refining to use.
The utility model is realized with following technical scheme: a kind of mine explosion-suppression escope comprises casing, is installed in the LCDs on the casing and is installed in the display circuit in the casing and looks the screen signal conversion module; Described casing is the flame-proof type casing that steel plate is made, and inside is explosion-proof chamber, and the front on the casing is provided with the Qianmen, and form is installed on the Qianmen, and form is in the outside of LCDs, and the side of casing is equipped with the loudspeaker mouth.
The beneficial effect of the utility model is: this display casing is a flame-proof type, is specially adapted to use in the environment of flammable explosive gas.
