Abstract
The invention discloses a flame-proof intrinsic safety type light-emitting diode (LED) tunnel emergency lamp for mine, which solves the problems that the conventional tunnel emergency lamp for coal mine does not have an emergency function and inconvenience is brought to the equipment, signal cabins and distribution rooms after power failure are solved. The flame-proof intrinsic safety type LED tunnel emergency lamp for mine is characterized in that a group of lithium-ion storage batteries are arranged in a lamp shell, and when the power fails, the emergency lamp is driven to continuously work by the storage batteries. The flame-proof intrinsic safety type LED tunnel emergency lamp for mine is beneficial to the operation of the coal mine equipment, the signal cabins and the distribution rooms after power failure, is safe after power failure and is suitable for tunnel illumination of all mines.
Description
Technical field:
The invention belongs to the technical field that mine working lighting apparatus is made, be specifically related to a kind of mine flameproof and intrinsic safety type LED tunnel emergency light, be applicable to all mine working illuminators.
Background technology:
Known to inventor, the lighting that coal mine down-hole tunnel is used at present, single old, the power consumption of structure, function imperfection, service life is short, in function, do not there is the emergent standby illumination after power failure, very inconvenient after main equipment place, down-hole, important access adit, switchgear house, signal cabin etc. are had a power failure, also safety is caused a hidden trouble.
Summary of the invention:
The object of the invention is exactly in order to overcome above weak point, a kind of novel structure, energy-conservation, long service life is provided, and has after power failure, and emergency standby power can continue to provide the mine flameproof and intrinsic safety type LED tunnel emergency light of 3 hours above electric energy.
Technical scheme of the present invention is to realize like this, described mine flameproof and intrinsic safety type LED tunnel emergency light, it is characterized in that arranging a cuboid lamp box 1, at cuboid lamp box 1 middle part, be provided with terminal block cover 2, between cuboid lamp box 1 and terminal block cover 2, sealing joint strip 3 is set, at the middle part of terminal block cover 2, order is connected with metal baffle 5 successively, packing ring 6, the connection jaws that sealing ring 7 and loudspeaker nozzle 4 form, the two ends of terminal block cover 2 are provided with connection bolt 8, in the bottom of cuboid lamp box 1, be provided with lamp bracket 17, in lamp bracket 17 bottoms, by screw 12 nuts 13, arrange and be fixedly connected with lampshade lid 9, glass rubber cushion 10 and glass 11.In cuboid lamp box 1 shell, left side is provided with LED chip controller 15, and binding post 16 is set on LED chip controller 15, and nickel-hydrogen accumulator 14 is arranged on right side in cuboid lamp box 1 shell.In lamp housing, be provided with the LED chip controller 15 of an illuminating lamp, LED chip controller is by power rectifier → voltage stabilizing, electric current and voltage duplicate protection constant pressure and flow, and backup battery charge-discharge circuit forms.Backup battery selects Ni-MH battery to form, and its capacity is 6AH, and charging current is controlled at below 0.5A; during Alternating Current Power Supply, battery is in trickle floating charge state, when exchanging power failure; by storage battery power supply, power-on time 2 hours, this circuit board is provided with and prevents accumulator super-charge and over-discharge protection circuit.
