Abstract
The utility model discloses a novel environment friendly and energy saving type mine safety cap light, comprising a lamp holder (1), a battery casing and a cable; the battery casing is fixed by a screw (5) from a top cover (4); a battery trough (7) is arranged in the battery casing; a controller is also arranged in the battery casing; the cap lamp of the utility model adopts a three-core cable to charge and discharge so as to change a charge and discharge way of a mine lamp, thereby helping to improve the charge characteristic and the discharge characteristic of the mine lamp. The controller is used for the constant current control of a discharge circuit and the buffer lightening control of a bulb at the starting time and the power transfer of the supervoltage of a nickel-hydrogen battery after charging to length the service life of the battery and extend the effective discharging time of the battery so as to realize the purpose of protecting the battery and the bulb.
Description
One, technical field
The utility model relates to a kind of special electric equipment, is mining down-hole portable lighting, and it is to be the downhole portable illuminations of power supply with the Ni-MH battery, specifically a kind of environment-friendly energy-saving type mining safety helmet lamp.
Two, background technology
The existing Ni-MH battery of existing mining safety helmet lamp is the mine lamp of power supply, in use all adopts twin core cable and short-circuit protection, because Ni-MH battery charging voltage height often burns out bulb in the use, influence is normally used.
Three, summary of the invention
It is good that the purpose of this utility model just provides a kind of charge and discharge performance, has safe, environment-friendly energy-saving mining safety helmet lamp easily that bulb is lighted buffering control, Energy Saving Control, constant-current discharge control circuit.
The purpose of this utility model is achieved in that the environment-friendly energy-saving type mining safety helmet lamp of being made up of lamp holder, battery case, cable, battery case is fixed by screw by loam cake, be provided with battery case in the battery case, its main points are: also be provided with controller in the battery case, cable is a three-core cable, one end and the lamp holder of three-core cable link, and its other end passes the rubber sleeve and controller b, e, the f that are fixed in loam cake and joins, and controller a, d end links with the Ni-MH battery positive and negative electrode.Three-core cable is 3 * 0.5mm
2～3 * 2mm
2, it is withstand voltage to be 5～500V.Said controller pulsewidth modulation TL494 integrated circuit, 9 pin of TL494 directly connect with power 6N10, and 4 pin and the bleeder circuit of TL494 link, and 6 pin of TL494 are by capacitor C
1Link with 13 pin of TL494, power switch passes through resistance R
1Link with the f end.
Four, description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is a three-core cable schematic diagram among Fig. 1;
Fig. 3 is the utility model middle controller block diagram;
Fig. 4 is the fundamental diagram of Fig. 3.
Five, the specific embodiment
As shown in Figure 1 and Figure 2, the utility model embodiment is: the environment-friendly energy-saving type mining safety helmet lamp of being made up of lamp holder (1), battery case, cable, battery case is fixing by screw (5) by loam cake (4), be provided with battery case (7) in the battery case, cable is three-core cable (2), one end of three-core cable (2) and lamp holder (1) link, and its other end passes and links with the battery positive and negative electrode after the rubber sleeve (3) that is fixed in loam cake (4) joins with controller (9).
As shown in Figure 3, Figure 4, anode and controller a end link, and link with output b simultaneously, through voltage-stabiliser tube w
1, resistance R
1After the voltage stabilizing, send 4 pin of IC, R
2With D
1Take out 1 pin and 6 pin that 0.7V voltage send IC after the dividing potential drop, between 2 pin of IC and 5 pin and meet capacitor C
1, with D
2Constitute oscillating impulse, export the square-wave pulse of variable-width at 9 pin of IC, when a, b terminal voltage are 5.5V～6V, the output pulse duty factor is 0.85～0.92, and when a, b terminal voltage were 5V～5.4V, the output pulse duty factor was 0.93～0.98, when a, b terminal voltage are that 5V is when following, output b, e terminal voltage dutycycle are 100%, when b, e terminal shortcircuit, are output as constant current 340mA.
Workflow is that anode flows to the b end through a end, simultaneously through w
1Send into 4 pin of IC, the alternating voltage after the pulse modulated after the 9 pin output modulation of IC is through T
1After the amplification, between b end and a end, provide the square-wave voltage of variable-width, DC voltage is modulated into dc pulse voltage for bulb power, in the process of modulation, realize buffering, reach the purpose of control.Flow through the electric current of bulb at R
3Last acquisition 0.06V voltage with delivering to 3 pin of IC after its output, is realized constant output when voltage surpasses this value, reach the purpose of protection.
Adopt three-core cable of the present utility model, changed the form of mine lamp charge and discharge, help improving the charge characteristic and the flash-over characteristic of mine lamp.Adopt controller that discharge loop has been carried out constant current control; cushion when bulb is started and light control; the Ni-MH battery charging back high voltage that finishes is carried out power transfer to prolong bulb service life, prolong battery effective discharge time, reach the protection battery, the purpose of protection bulb.
