Abstract
The utility model discloses an explosion-proof case for a central control device used in an environment with explosive gas, which comprises an explosion-proof front cover. A sealing ring is arranged on a combined surface of the explosion-proof front cover with the peripheral wall of a case body, the case body consists of a main case body and an interface case body by means of combination, the interface case body is disposed on the rear of the main case body, inserting slots are fixed to the left lateral wall, the right lateral wall and the bottom wall of the main case body, a horizontal supporting plate and a longitudinal partition plate which are inserted in the inserting slots in a sliding manner divide the main case body into a plurality of chambers which are communicated with each other, and connecting terminal plates, input and output terminals of electric appliances and grounding indicating panels are disposed in the interface case body. The explosion-proof case has the advantages that the explosion-proof case provides a small underground environment for safe operation of the central control device in a coal mine, namely, the operating environment of the central control device is separated from an underground severe external environment, and the explosion-proof case is explosion-preventive, waterproof and dustproof, is reasonable in internal layout and meets the requirement of underground operational safety.

Background technology
Along with the raising of country to Safety of Coal Mine Production and high-yield and high-efficiency automation requirement, the demand of underground equipment central control unit is also increasing.Because the special explosion gas environment in down-hole makes the industrial control device of conventional structure directly not use safely in this environment.
Summary of the invention
The purpose of this utility model is to provide a kind of flameproof cabinet that is used for the central control unit that the explosion gas environment uses, and this flameproof cabinet can be isolated the abominable overall situation of operational environment and down-hole of central control unit, guarantee the operation that it is safe.
For achieving the above object, the utility model can be taked following technical proposals:
The flameproof cabinet that is used for the central control unit that the explosion gas environment uses described in the utility model, comprise the flame proof protecgulum, the faying face of described flame proof protecgulum and casing wall is provided with sealing ring, and described casing is combined by main box and the interface casing that is arranged on the main box rear portion; Be fixed with slot on the left and right sides sidewall of described main box and the diapire, horizontal supporting plate and the vertical division board that is inserted in the described slot that slide is divided into a plurality of chambers that are interconnected with main box; Be provided with the input/output interface and the ground connection indicator board of terminal board and electrical installation in the described interface casing.
Be laid with fish eyelet on described horizontal supporting plate and the vertical division board; When playing support and isolating electric elements, can well dispel the heat again, not produce pressure piling.
Described vertical division board is provided with two temperature-dropping fans of direction of rotation; Guarantee can not occur in the whole main box chamber the too high phenomenon of local temperature.
Be provided with power supply chamber, mainboard chamber, components and parts chamber and display drive plate chamber in the described main box; Can effectively save the space, it is more neat to connect up; Mainboard fixedly installs and is drawer type in the described mainboard chamber, is convenient to the installation and maintenance mainboard; Described mainboard is provided with the circuit fixture in the chamber, can the circuit in mainboard chamber is neatly fixing, and reduce circuit friction and connector and partly damage.
The upper top of described main box is provided with suspension ring, and lower bottom part is provided with bearing.
Advantage of the present utility model is the explosion separation structure that adopts main box and interface casing to combine to the central control unit used in the well shooting gaseous environment, and the sealing ring that is provided with on protecgulum and the casing faying face can prevent again that in flame proof sealing and humid air enter box house electric elements are caused damage; Horizontal supporting plate in the main box and vertical division board are divided into a plurality of chambers that are interconnected (as power supply chamber, mainboard chamber, components and parts chamber and display drive plate chamber etc.) with main box, can effectively utilize the space, do not produce pressure piling, wiring is more neat simultaneously; The interface casing that is arranged on the main box rear portion can make all circuits all from then on come in and go out, and is convenient to wiring and checks the assurance security of operation.The utility model will provide a subenvironment in the coal mine downhole safety operation for central control unit, it is isolated to be about to the abominable external environment condition in the operational environment of central control unit and down-hole, play and go back water proof and dust proof explosion-proof the time, the outward appearance compact, interior layout is reasonable, has satisfied the demand of down-hole security of operation.
