It is in groups monomer series-connected that bonding conductor is used for lead acid accumulator, first bonding conductor is sleeved in natural rubber cover, bonding conductor is longer than at rubber sleeve two ends, because rubber sleeve has flexible flexibility, by outside for rubber sleeve two ends turnup, expose bonding conductor two ends, the mode of welding is adopted to be connected with the pole of lead acid accumulator monomer bonding conductor, again rubber sleeve is turned over downwards after firm welding, make the two ends of rubber sleeve envelope plumbic acid and store pole on machine battery monomer, the pole of rubber sleeve is completely coated bonding conductor and lead acid accumulator monomer, effectively prevent the dust accidentally falling into secondary battery jar inside to contact with bonding conductor, eliminate bonding conductor and pole to ignite because local temperature is too high or produce electric spark combustible dust or imflammable gas and the hidden danger that sets off an explosion.Natural rubber is acidproof, high temperature resistant, anti-aging simultaneously, very suitable lead-acid battery environment.
The surrounding downward bending of described outer cover plate extends, until exceed edge on dust board.Outer cover plate neither contacts with dust board, ensure that enough ventilation effects, can effectively prevent dust from entering casing again, ventilation hole simultaneously on the ventilating opening of case lid and box side forms cross-ventilation, can get rid of the hydrogen in casing fast, hydrogen is not easily assembled, and gets rid of hidden danger.
Frp layer is coated with inside described power box.The insulation resistance of power box can reach 100M Ω, far away higher than standard index 5M Ω.
Described lead acid accumulator monomer is the lead acid accumulator with explosion insulation performance.
The corner of described outer cover plate is fixed on case lid by column.Described ventilation hole is located at the bottom of the left side plate of power box.Whole power box inside forms cross-ventilation, and row's hydrogen, ventilation effect are better.
Beneficial effect of the present invention: invention increases the security performance of dust explosion protection vehicle in running, has ensured the personal safety as well as the property safety of site operation personnel.
One, the present invention adopts natural rubber to overlap and not only envelopes bonding conductor, and the pole of lead acid accumulator is also wherein coated, effectively can block bonding conductor to comprise pole and contact with the combustible dust accidentally falling into power box inside, eliminate bonding conductor and comprise pole and to ignite combustible dust and the hidden danger that sets off an explosion because local temperature is too high or produce electric spark; And natural rubber is acidproof, high temperature resistant, anti-aging, very suitable lead-acid battery environment.
Two, the present invention adopts and be provided with ventilating opening on case lid, the surrounding of ventilating opening is vertically arranged with dust board, the top of dust board is provided with the power box structure that the anti-dust type power supply case lid of the outer cover plate covering ventilating opening and side plate are provided with ventilation hole, effectively prevent from dust from entering supply unit inside by power box or case lid to assemble, eliminate and assemble dust by the hidden danger of lighting, ventilation hole simultaneously on the ventilating opening of case lid and box side forms convection current, ventilation effect is better, hydrogen in quick eliminating casing, prevent hydrogen from assembling, set off an explosion.
Three, anti-dust type power supply cover structure of the present invention is simple, saves and makes material, reduces production cost.
