Description
Technical field
The utility model relates to power technique fields, particularly relates to a kind of emergency mine lamp power device.
Background technology
Mine lamp is the abbreviation of mine-use lamp or Mining lamps and lanterns, the general designation of the special lighting in mine.Mine lamp is applicable to the place that underground coal mine has gas (methane race) coal dust explosion hazard; Shaft bottom mining roadway, also can use in the infrastructure mine tunnel having trickle larger and chamber.But, because the service time of mine lamp is long, need a large amount of supplies of electric power.Once not have electricity to affect work, the utility model object is to provide a kind of emergency mine lamp power device, to ensure that mine lamp is not having in electric situation and can emergent charging work on.
Existing supply unit, owing to powering to multiple mine lamp simultaneously, makes the power consumption of supply unit fast, and when the serious power shortage of Vehicular accumulator cell, then cannot provide required direct current to mine lamp, cause mine lamp to work.
In view of the defect existed in above prior art, be necessary it to improve further, make it have more standby practicality.
Utility model content
The utility model provides a kind of emergency mine lamp power device, to solve in prior art when the serious power shortage of supply unit, then cannot provide direct current needed for power for operation to mine lamp, cause the problem that mine lamp cannot work.
The utility model is taked following technical scheme to realize: a kind of emergency mine lamp power device, it comprises the first resistance, second resistance, relay and diode, described first resistance is connected with described second resistant series, the former limit of described second resistance and described relay is connected in parallel, one end of the secondary of described relay is connected with voltage negative pole, the other end of the secondary of described relay is connected with described Diode series, the other end of described diode is connected with positive polarity, the 3rd resistance is also shown in described diode two ends, described diode is connected with described relay afterwards and constant voltage circuit output is connected in parallel.
Particularly, described first resistance is equal with the resistance value of described second resistance; Described constant voltage circuit output is provided with multiple supply unit access port; The resistance value of described first resistance is greater than the resistance value of described 3rd resistance.
The utility model has following beneficial effect in sum: the utility model is simple and reasonable, be connected with the second resistant series by the first resistance, a series of electricity is connected second resistance arranges with the former limit of relay is connected in parallel etc., achieve when mine lamp power shortage deficiency, can power specially for mine lamp, to ensure that mine lamp can normally work; The diode arranged, the 3rd resistance can play the effect of current limliting, the electric current of supply unit is reduced, plays the effect of protection power source device.
