Abstract
The utility model relates to a flameproof and intrinsically safe power supply box for mine. The flameproof and intrinsically safe power supply box for mine comprises a closed shell formed by welding steel plates; a standby battery compartment arranged on the lower part in the shell and fixedly provided with a standby battery; a circuit board fixed above the standby battery by support poles on the two ends of the standby battery compartment, wherein a power supply input terminal connected with the standby battery and an intrinsically safe output terminal are arranged on the circuit board; and circuit interfaces arranged on the two ends of the shell. The flameproof and intrinsically safe power supply box is manufactured and processed by the steel plates, thus the box is safe, reliable, firm and durable. The line incoming uses a compaction nut type introducing device, and the line connection process is convenient. The inner part of the power supply box uses the core plate structure, thus the core plate structure is wholly disassembled and conveniently maintained and repaired.
Description
Technical field
The utility model belongs to the mining equipment technical field, relates to a kind of power supply box, especially a kind of mine flameproof and intrinsic safety type power supply box.
Background technology
China is big coal country, output of coal leaps to world front three, because most of coal all is stored in the underground, so must exploit with the form of mine, and underground work is breakneck for coal workman's personal safety, a lot of coal mining accidents all can occur every year in China, and all can pay each time the cost of blood, in these coal mining accidents, more common is exactly that down-hole toxic gas or coal powder density are too high, the down-hole is easy to set off an explosion if there is power consumption equipment or power source fire-striking, causes casualties and economic loss.Therefore, down-hole
Especially the too high meeting of dust directly affects downhole safety, and easily causes blast, therefore, needs a kind of device that can effectively get rid of the down-hole coal dust.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provide a kind of mine flameproof and intrinsic safety type power supply box, this power supply box compact conformation, reasonable in design, its internal electric source and external environment can be kept apart, prevent that power source fire-striking from causing accident.
The purpose of this utility model solves by the following technical programs:
This mine flameproof and intrinsic safety type power supply box comprises the closure casing by Plate Welding; Bottom in housing is spare battery chamber, is fixedly installed reserve battery; The support column that arranges by the spare battery chamber two ends above reserve battery is fixed with circuit board, is provided with the power input terminal and the intrinsic safety lead-out terminal that are connected with reserve battery on the described circuit board; The two ends of described housing are provided with circuit interface.
One side lower part of above-mentioned housing is provided with grounding screw.
The loam cake of above-mentioned housing is combined closely by bolt and bottom.
Bottom in the above-mentioned housing is provided with a plurality of grooves, and described reserve battery is placed on the groove.
The foregoing circuit interface is clamp nut formula introducing device.
Mine flameproof and intrinsic safety type power supply box of the present utility model adopts the steel plate manufacturing to process, and is safe and reliable, sturdy and durable.Inlet wire adopts clamp nut formula introducing device, easy-to-connect.The inner machine core board structure that adopts can integral body be shirked, and is easy to maintenance.
