Abstract
The utility model discloses an explosive-proof power box used for a mine locomotive. The explosive-proof power box includes a storage battery. The explosive-proof power box is characterized in that an explosive-proof shade is arranged outside the storage battery; the explosive-proof shade is provided with a wire hole; a rubber gasket and a plug bolt are arranged in the wire hole; the rubber gasket and the plug bolt are both inside provided with holes; and male threads of the plug bolt and female threads of the wire hole are fastened by each other in a mating manner. The explosive-proof power box has positive effects that parts that may produce arc sparks are isolated and gas explosion caused by the produced sparks is avoided, so that safety is guaranteed. Besides, gas is prevented from entering into the box body by adopting the explosive-proof device with a wire running through.
Description
Technical field
The utility model patent relates to a kind of mine locomotive flame proof power supply box.
Technical background
In the subsurface environment of ore deposit, owing to existing high concentration explosion gas (gas), thus can not produce some sparks, otherwise just may cause the serious accident of loss of life or personal injury.
Mine car is with 12v storage battery, and the direct current in it, for light, loudspeaker, starter etc., is all connected to wire on the positive and negative terminal of storage battery, and be exposed in air, cause electric spark once produce by electric arc, after touching methane gas, just likely explosion caused, generation accident.
Summary of the invention
The purpose of this utility model is to provide a kind of mine locomotive flame proof power supply box to make up the deficiency of prior art.
The utility model is to realize the technical scheme that object adopts:
Mine locomotive flame proof power supply box, comprises storage battery, it is characterized in that: have flame proof cover outward at storage battery, wired hole on flame proof cover, in line hole, be provided with rubber blanket and plug bolt, all porose in rubber blanket and plug bolt, the external screw thread of plug bolt and and the screw-internal thread fit of wire hole realize fastening.
Optimize, described line hole has 2, and corresponding, the quantity of rubber blanket and plug bolt is all also 2.
Good effect of the present utility model is: the position that likely produces arc spark is isolated, and the spark of its generation can not cause the gas explosion in environment, thereby has guaranteed safety.The threading explosion-protection equipment arranging in addition has also effectively prevented that methane gas from entering casing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
embodiment:
In the drawings: the 1st, storage battery, the 2nd, flame proof cover, the 4th, line hole, the 5th, rubber blanket, the 6th, plug bolt, the 7th, hole.
When use, flame proof cover 2 is by storage battery 1 and extraneous isolation.Positive wire and negative wire pass by two line holes 4.
Processing for lead-in wire: if the dealing with improperly of line hole 4, methane gas just likely enters, in the utility model, the hole 7 by electric wire through rubber blanket 5 and plug bolt 6, then rubber blanket 5 and plug bolt 6 are put to (line hole 4 is the holes that have stage) in line-entering hole 4, tighten again plug bolt 6, plug bolt 6 pushes rubber blanket 5, makes it distortion, thereby makes quality of rubber materials only wrap electric wire, to guarantee the gap that do not have air to enter, thereby guarantee safety.
Claims (2)
