Description

Mining ni-mh power safety cap lamp

The utility model relates to a kind of colliery or other mining industry and tunnel, illuminations that night, wild operating personnel wore, particularly a kind of mining safety helmet lamp that adopts nickel metal cylinder alkaline storage battery.

At present, the mine lamp that underground operators is worn use mostly adopts the lead-acid accumulator power supply, and its weak point is: 1, Heavy Weight, volume are big, generally reach 2300 grams, make subsurface environment wear inconvenience with regard to abominable staff originally, overload; 2, need special messenger's maintenance and repair, not only strengthened use cost, and when maintenance is inconsiderate, can make its lost of life even scrap; 3, contaminated environment and human body, mend electrolyte (strong acid) owing to often add in the lead-acid accumulator, in use, cause seepage easily, thereby corrosion user's clothes and skin, simultaneously because its main raw material(s) is a heavy metal lead, produce and use in reach end-of-life and scrap after, environment is caused very big pollution; 4, lack service life, its cycle life generally is no more than 400 times.

China's utility model patent discloses a kind of " the non-maintaining high energy mine lamp of ni-mh " (patent No.: 99237881.8), though this mine lamp also is a kind of ni-mh mine lamp, but owing in battery case, be provided with three mutual disjunct hollow drums, the Ni-MH battery core is housed in the drum, its weak point is: 1, voltage (normal voltage is 3.6V) on the low side when the connection power supply is lighted lamp, needs big electric current by making the bulb heating luminous, thermal conductivity factor increases, and makes a part of electric energy become heat energy and consumes; 2, manufacturing expense increases, and at first, though it has saved the sealing metal shell of Ni-MH battery, seem the expense of saving and (material), and in fact not only need invest huge special equipment, and artificial expending also increases, and has increased manufacturing cost indirectly; Secondly, independently in the drum, sealing explosion-protection equipment (rubber ball) pond air valve is inconsistent with Ni-MH battery core be sealed in directly that the ABS engineering plastics make three, and three series connected battery cores influence each other, and cause the mine lamp capacity to descend the lost of life; 3, because its voltage is low, and in charging process, the big electric current of domestic demand can be full of at the appointed time, therefore cause charging system (element) heating, therefore the lost of life needs to increase the charging system manufacturing cost.

The purpose of this utility model be exactly provide at the weak point of above-mentioned mine lamp that a kind of volume is little, in light weight, dependable performance, non-maintaining, pollution-free, the life-span long, the mining ni-mh power safety cap lamp of use and low cost of manufacture.

Technical solution of the present utility model is: a kind of mining ni-mh power safety cap lamp; it comprises power supply assembly, short-circuit protector, head lamp assembly and mining Xe lamp bulb; it is characterized in that: described power supply assembly is made of the nickel metal alkaline batteries of loam cake, battery case box, bottom and series connection; wherein, be whole hollow shape in the battery case box.

Short-circuit protector described in the utility model technical solution can be the electronics thermosensitive protection switch.

Can be whole cylinder type hollow shape in the battery case box described in the utility model technical solution, the nickel metal cylinder alkaline storage battery group of four joint series connection is housed.

Can be pasted with the electronics thermoswitch on the shell of nickel metal (cylinder) the alkaline storage battery group (11) described in the utility model technical solution.

The utility model is owing to adopt whole hollow shape battery case box, nickel metal alkaline batteries and mining Xe lamp bulb, thereby volume is littler, weight is lighter, use and manufacturing cost are lower, illuminance is under the prerequisite that is not less than 11 hours of lighting a lamp continuously of national regulation, reach 2000LX (measured value just of lighting a lamp) and 900LX (the 11 hours measured values of lighting a lamp), be higher than national standard 600LX (lighting a lamp just) and 250LX (lighting a lamp 11 hours) far away.Owing to adopted the electronics thermosensitive protection switch that constitutes by heat-sensing material, heat-sensing shell fragment and contact, made the short-circuit protection performance better.Owing on nickel metal alkaline batteries shell, be pasted with the electronics thermosensitive protection switch, thereby when charging, when the charging system fault caused the battery pack abnormal heating, the electronics thermosensitive protection switch can disconnect just, plays a protective role.The utlity model has that volume is little, in light weight, dependable performance, non-maintaining, pollution-free, the life-span long, the characteristics of use and low cost of manufacture, overcome the deficiencies in the prior art part, thereby reached the purpose of this utility model.

The utility model is described in further detail below in conjunction with accompanying drawing:

Mining ni-mh power safety cap lamp loam cake, battery case box and bottom all adopt the plastics of toughness and high abrasion resistance to make respectively as Fig. 1, Fig. 2 and shown in Figure 3.The both sides of loam cake porose respectively 1 are used for bolt and connect with the battery case box, and its upper lobes partly has a hole 2 to be used to assemble the mine lamp cable.Battery case box top has two holes 3 to be used for the outlet of battery pack positive and negative electrode, has three binding posts 4 to connect the positive level of battery pack, negative pole and electronics thermosensitive protection switch 7 respectively.There are two bossings both sides, battery case box top, difference embedded nut 5, and corresponding with the hole 1 of loam cake both sides, the battery case box is provided with belt buckle 6, so that the operating personnel wears between waist.Acting as of bottom after batteries is packed the battery case box into, gives fixing seal with ultrasonic equipment.The head lamp assembly is made up of mine lamp private cable line and lamp holder, and is same as the prior art.

Electronics thermosensitive protection switch 7,12 schematic diagrams as shown in Figure 5, it is made up of heat-sensing material 8, heat-sensing shell fragment 9, contact 10 and metal shell.When the mine lamp line work just often, it can pass through the 2A electric current; When opening circuit appears in mine lamp, the immediate current 2A that passes by, cause the 8 moments heating of heat-sensing material, heat makes heat-sensing shell fragment 9 reversal deformations force contact 10 to disconnect, after 8 coolings of heat-sensing material, heat-sensing shell fragment 9 restores to the original state contact 10 combinations, constantly repeat thus, get rid of the back up to fault and recover normal.Another electronics thermosensitive protection switch 12 strings are in battery pack 11; and stick on the battery case; it act as, and causes the battery adstante febre (battery allows to reach 45 ℃ in charging process) that overcharged when the charging system Automatic Control Component is malfunctioning, and when surpassing 45 ℃ temperature; electronics thermosensitive protection switch 12 disconnects; charging process temporarily stops, and after battery temperature lowered, electronics thermosensitive protection switch 12 recovered normal; so repeatedly, get rid of up to the charging system fault.

The mine lamp circuit interconnect pattern as shown in Figure 6, nickel metal cylinder alkaline storage battery group 11, electronics thermosensitive protection switch 12 and lamp holder assembly 13 and mining Xe lamp bulb 14 forming circuit loops, mode of connection and head lamp assembly and existing lead-acid accumulator mine lamp are basic identical.Battery pack 11 adopts the nickel metal cylinder alkaline storage battery group of four joint series connection, and nominal voltage is 4.8V.
