Abstract
The utility model discloses a kind of mine explosion-suppression power supply box, comprise casing, case lid, in described casing, be provided with power panel; Described power panel is drawn lead-out terminal, the first conductor, be also provided with the second conductor in described casing, this second conductor is electrically connected with external power source, is provided with the 3rd conductor between described first conductor and described second conductor, and the 3rd conductor is connected with described case lid; When described case lid is closed, described 3rd conductor and described first conductor, the second conductor contact, when described case lid is opened, described 3rd conductor and described first conductor, the second free of conductors.Of the present utility model when opening case lid auto-breaking, ensure that the fail safe of operator, structure is simple, practical.
Description
Technical field
The utility model relates to a kind of mine explosion-suppression power supply box.
Background technology
At present, mine explosion-suppression power work in down-hole, thus demand fulfillment underground work environmental requirement.Mine explosion-suppression power supply box is mainly used in the places such as colliery, metallic ore, tunnel, subway, provides working power for needing the equipment providing DC power supply.Existing mine explosion-suppression power supply has text prompt on casing, and the first deenergization of prompting operator opens casing again, in order to avoid cause security incident, but in practical operation, a lot of operator often ignores prompting, causes very large potential safety hazard.
In Chinese Patent Application No.: disclose a kind of mine locomotive flame proof power supply box in 201320813957.9, comprise storage battery, flame proof cover is had outside storage battery, flame proof cover there is string holes, be provided with rubber blanket and plug bolt in string holes, 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, also there is potential safety hazard in this technical scheme, is further improved in use.
Utility model content
For the problems referred to above, the utility model provides a kind of mine explosion-suppression power supply box, and structure is simple, use safety.
In order to solve the problem, the technical scheme that the utility model provides is:
A kind of mine explosion-suppression power supply box, comprises casing, case lid, is provided with power panel in described casing; Described power panel is drawn lead-out terminal, the first conductor, be also provided with the second conductor in described casing, this second conductor is electrically connected with external power source, is provided with the 3rd conductor between described first conductor and described second conductor, and the 3rd conductor is connected with described case lid; When described case lid is closed, described 3rd conductor and described first conductor, the second conductor contact, when described case lid is opened, described 3rd conductor and described first conductor, the second free of conductors; Such design can ensure that operator can the unpacking lid of safety hit.
Preferably, described casing is provided with air-vent; Convenient heat radiation.
Preferably, described air-vent is coated with waterproof net; Prevent moisture from entering in casing.
Preferably, foamed aluminium board is provided with between the inwall of described power panel and described casing; Foamed aluminium board density is little, high-selenium corn, impact capacity are strong, high temperature resistant, fire protecting performance is strong, anticorrosive, sound insulation and noise reduction.
Preferably, described case lid is provided with magnetic part, and on described casing, correspondence is provided with adhesive parts; Avoid the generation of potential safety hazard.
Compared with prior art, the beneficial effects of the utility model are:
Of the present utility model when opening case lid power panel auto-breaking, ensure that the fail safe of operator, structure is simple, practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below the utility model is described further:
Composition graphs 1: a kind of mine explosion-suppression power supply box, comprises casing 1, case lid 2, is provided with power panel 3 in casing 1; Power panel 3 is drawn lead-out terminal 4, first conductor 5, be also provided with the second conductor 6 in casing 1, this second conductor 6 is electrically connected with external power source, is provided with the 3rd conductor the 7, three conductor 7 and is connected with case lid 2 between the first conductor 5 and the second conductor 6; When case lid 2 is closed, the 3rd conductor 7 contacts with the first conductor 5, second conductor 6, and when case lid 2 is opened, the 3rd conductor 7 is separated with the first conductor 5, second conductor 6; Such design can ensure that operator can the unpacking lid of safety hit.
Casing 1 is provided with air-vent 8; Convenient heat radiation.
Air-vent 8 is coated with waterproof net 9; Prevent moisture from entering in casing.
Foamed aluminium board 10 is provided with between the inwall of power panel 3 and casing 1; Foamed aluminium board 10 density is little, high-selenium corn, impact capacity are strong, high temperature resistant, fire protecting performance is strong, anticorrosive, sound insulation and noise reduction.
Case lid 2 is provided with magnetic part 11, and on casing 1, correspondence is provided with adhesive parts 12; Timely closedown case lid 2, avoids the generation of potential safety hazard.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
