Summary of the invention
According to deficiency of the prior art, the invention provides the special-purpose explosion-proof electrical source device of dust atmosphere, anti-dust performance is good, and ventilation by forced draft row hydrogen is quick, stop bonding conductor and pole absorption dust and the hidden peril of explosion that forms, make the explosion-proof electrical source device that explosion-proof vehicle can safe operation in dust atmosphere.
The present invention is achieved through the following technical solutions:
The special-purpose explosion-proof electrical source device of dust atmosphere, comprise power box, be placed with a plurality of lead acid accumulator monomers in the power box, be connected by bonding conductor between the lead acid accumulator monomer, the top of power box is provided with case lid, is set with rubber sleeve on the described bonding conductor, case lid is provided with ventilating opening, vertically be arranged with dust board around the ventilating opening, the top of dust board is provided with the outer cover plate that covers ventilating opening, and the side plate of power box is provided with ventilation hole.
It is in groups monomer series-connected that bonding conductor is used for lead acid accumulator, first bonding conductor is sleeved in the natural rubber cover, bonding conductor is longer than at the rubber sleeve two ends, because rubber sleeve has flexible flexibility, with the outside turnup in rubber sleeve two ends, expose the bonding conductor two ends, adopt the mode of welding to be connected with the pole of lead acid accumulator monomer bonding conductor, again rubber sleeve is turned over downwards after the firm welding, make the two ends of rubber sleeve envelope plumbic acid and hold pole on the machine battery monomer, rubber sleeve has coated the pole of bonding conductor and lead acid accumulator monomer fully, prevented that effectively the dust that accidentally falls into secondary battery jar inside from contacting with bonding conductor, eliminated bonding conductor and pole too high or produce the electric spark hidden danger that combustible dust or imflammable gas set off an explosion of igniting because of local temperature.Natural rubber is acidproof, high temperature resistant, anti-aging simultaneously, very suitable lead-acid battery environment.
Downward bending extends around the described outer cover plate, until surpass dust board top section.Outer cover plate neither contacts with dust board, has guaranteed enough ventilation effects, can prevent effectively that again dust from entering casing, the ventilating opening of case lid and the ventilation hole on the box side form cross-ventilation simultaneously, can get rid of fast the hydrogen in the casing, hydrogen is difficult for assembling, and gets rid of hidden danger.
Described power box inboard is coated with frp layer.The insulation resistance of power box can reach 100M Ω, is higher than standard index 5 M Ω far away.
Described lead acid accumulator monomer is the lead acid accumulator with explosion insulation performance.
Four jiaos of described outer cover plate are fixed on the case lid by column.Described ventilation hole is located at the bottom of the left side plate of power box.The inner cross-ventilation that forms of whole power box, row's hydrogen, ventilation effect are better.
Beneficial effect of the present invention: the present invention has improved the security performance of dust explosion protection vehicle in running, has ensured site operation personnel's personal safety as well as the property safety.
One, the present invention adopts the natural rubber cover not only to envelope bonding conductor, and the pole of lead acid accumulator also coated wherein, can effectively block bonding conductor and comprise that pole contacts with the combustible dust that accidentally falls into power box inside, eliminate bonding conductor and comprised that pole is too high or produce the electric spark hidden danger that combustible dust sets off an explosion of igniting because of local temperature; And natural rubber is acidproof, high temperature resistant, anti-aging, very suitable lead-acid battery environment.
Two, the present invention adopts and is provided with ventilating opening at case lid, vertically be arranged with dust board around the ventilating opening, the top of dust board is provided with the anti-dust type power supply case lid of the outer cover plate that covers ventilating opening and the power box structure that side plate is provided with ventilation hole, prevent that effectively dust from entering supply unit inside by power box or case lid and assembling, eliminated and assembled the hidden danger that dust is lighted, the ventilating opening of case lid and the ventilation hole on the box side form convection current simultaneously, ventilation effect is better, get rid of fast the hydrogen in the casing, prevent the hydrogen gathering, set off an explosion.
