Abstract
The utility model discloses a kind of ventilating shaft power down warning device, belong to Mine Safety Appliances field.Comprise hummer BL and ventilating shaft power down trigger switch K, charging panel, rechargeable battery B and relay switch YJ, charging panel is arranged charging indicator light HD1 and the full pilot lamp HD2 of charging; Relay switch YJ control end connects level power supply, its normally closed contact YJ-1 is as the gauge tap of hummer, one termination rechargeable battery positive pole, another termination hummer BL, normally closed contact YJ-1 connects level power supply positive pole with the tie point of hummer BL by disconnector D.The utility model utilizes the retired lithium battery of mine lamp to make standby power supply, and when upper level power supply normally works, this device uses higher level's power work and to lithium cell charging, during higher level's power supply power-fail, this device automatically switches and uses lithium battery power supply.This device can also use as emergency light simultaneously, can save the expense purchasing emergency light in a large number.
Description
Technical field
The utility model relates to a kind of mine alarming device, specifically a kind of ventilating shaft power down warning device, belongs to Mine Safety Appliances field.
Background technology
Fire damp is the biggest factor affecting Safety of Coal Mine Production, and ventilation is heavy heavy in the weight of coal production, and central ventilation shaft is the throat thoroughfare of Safety of Coal Mine Production, knows the safety in production lifeblood in full ore deposit, is responsible for the production important business of air feed.For guaranteeing ventilation blower safe operation, first will guarantee safe power supply, therefore ventilating shaft has power down warning function.In prior art, ventilating shaft power down warning device is all use level power supply, and in the normal situation of upper level power supply, during ventilating shaft power down, warning device is sounded a buzzer warning.But when higher level's power fail, ventilating shaft can not get power supply, and at this moment warning device is also ineffective, can not play alarm function.
Summary of the invention
The purpose of this utility model is to provide a kind of ventilating shaft power down warning device, under higher level's power failure condition, even if can send ventilating shaft power down alarm.
For achieving the above object, a kind of ventilating shaft power down of the utility model warning device, comprise hummer BL and ventilating shaft power down trigger switch K, hummer BL and ventilating shaft power down trigger switch K connects in circuit, it is characterized in that, also comprise charging panel, rechargeable battery B and relay switch YJ, charging panel is arranged charging indicator light HD1 and the full pilot lamp HD2 of charging; Relay switch YJ control end connects level power supply, its normally closed contact YJ-1 is as the gauge tap of hummer, one termination rechargeable battery positive pole, another termination hummer BL, normally closed contact YJ-1 connects level power supply positive pole with the tie point of hummer BL by disconnector D, and charging panel and relay switch YJ parallel connection connect level power supply.
When upper level power supply normally works, relay YJ adhesive, its normally closed contact YJ-1 disconnects, and upper level power supply is powered to hummer BL, and charging panel charges to rechargeable battery B.Charging indicator light HD1 is bright, and after being full of electricity, HD2 is bright, and HD1 goes out.When higher level's power loss, relay YJ discharges, and normally closed contact YJ-1 closes, and rechargeable battery is powered to hummer BL, and disconnector D prevents rechargeable battery B back discharge.
The utility model, when higher level's power fail, automatically switches and to be powered by rechargeable battery, send ventilating shaft power down warning information in time, thoroughly solves the problem cannot reported to the police because of alarm device self dead electricity.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram;
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of ventilating shaft power down of the utility model warning device, comprise hummer BL and ventilating shaft power down trigger switch K, hummer BL and ventilating shaft power down trigger switch K connects in circuit, it is characterized in that, also comprise charging panel, rechargeable battery B and relay switch YJ, charging panel is arranged charging indicator light HD1 and the full pilot lamp HD2 of charging; Relay switch YJ control end connects level power supply, its normally closed contact YJ-1 is as the gauge tap of hummer, one termination rechargeable battery positive pole, another termination hummer BL, normally closed contact YJ-1 connects level power supply positive pole with the tie point of hummer BL by disconnector D, and charging panel and relay switch YJ parallel connection connect level power supply.
When upper level power supply normally works, relay YJ obtains electric, and its normally closed contact YJ-1 disconnects, and upper level power supply is powered to hummer BL, and charging panel charges to rechargeable battery B.Charging indicator light HD1 is bright, and after being full of electricity, HD2 is bright, and HD1 goes out.When higher level's power loss, relay YJ discharges, and normally closed contact YJ-1 closes, and rechargeable battery is powered to hummer BL, and disconnector D prevents rechargeable battery B back discharge.
The utility model, when higher level's power fail, automatically switches and to be powered by rechargeable battery, send ventilating shaft power down warning information in time, thoroughly solves the problem cannot reported to the police because of alarm device self dead electricity.
Further, one or one group bulb L in parallel with hummer, the utility model can also use as emergency light.
Further again, rechargeable battery can select Ni-MH battery, Ni-Cr battery, lithium battery etc., the utility model preferred lithium battery, for the retired lithium battery of mine lamp, save 1.2V/300mAh than original emergency light 3 and maintain good illumination effect one times, be equipped with 200 by each ore deposit, a group company considers by 20 units, and safety fire fighting emergency light every the lamp purchased needs 95 yuan.Utilize waste and old mineral light to transform, be then the profit of all saving, be: 200 × 20 × 95 × 10
-4=38 (ten thousand yuan).
Claims (3)
