Description
Technical field
The utility model relates to winning equipment field, especially relates to a kind of mine flame-proof and intrinsic safety type signal case.
Background technology
Winning equipment is because the circumstance complication of application, very high requirement is had to the reliability of equipment and fail safe, particularly for the winning equipment carrying out tunneling, a large amount of flammable explosive gas and dust is there is in tunnel, above-mentioned gas and dust run into naked light and very easily set off an explosion, this just requires that the equipment worked in such a case must meet high-level safety requirements, and all electric equipments must have the characteristic of flame proof and intrinsic safety.
Utility model content
In order to overcome above-mentioned technical problem, the utility model provides a kind of compact conformation, the mine flame-proof and intrinsic safety type signal case of use safety, and the technical scheme of employing is as follows:
Mine flame-proof and intrinsic safety type signal case, comprise the hexahedron metal outer wall of two sides opening, metal outer wall internal insulation is become explosion-proof chamber and intrinsic safety chamber by anti-explosion partition, intrinsic safety chamber comprises LED lamp panel and intrinsic safety type LED circuit, explosion-proof chamber comprises circuit carriers, circuit carriers is provided with interconnective voltage stabilizing circuit and storage battery, shielded type cable connects storage battery and intrinsic safety type LED circuit through anti-explosion partition, intrinsic safety type feed cable is connected with voltage stabilizing circuit through metal outer wall by cable interface, described metal outer wall one side is sealed by LED lamp panel, metal outer wall another side is sealed by end plate, described metal outer wall is also provided with normally closed relief valve.
Further, described metal outer wall upper end is provided with pedestal, and pedestal is provided with a plurality of set bolt.
Further, described voltage stabilizing circuit adopts AC127C voltage stabilizing circuit, and operating current is less than 0.15A.
Further, described end plate is fixed by the flange of bolt and metal outer wall.
Above-mentioned mine flame-proof and intrinsic safety type signal case is applicable to the place that underground coal mine has gas and dust explosion danger, according to mine requirement, various sign board is set, as sign board and the various indicative term such as " waiting room ", " down-hole central substation ", as " sending a car in front, takes care " etc.Be arranged on the place that down-hole is different, to point out staff to note, the generation of Accident prevention.
