The utility model relates to a kind of battery car automatic Regulation explosion-protection equipment.
Background technology
Load and unload in the place that battery car is widely used in containing explosive mixture in harbour, railway, goods yard, warehouse etc., pile and transport operation.Storage battery safety is most important, and improper use causes accumulator explosion easily.
On battery car, storage battery is the battery combination that places in the metal battery case.Storage battery can produce gas in charge and discharge process, gas increases to the battery case internal pressure is sharply increased, and as can not in time discharging gas, blasts easily.During operation, storage battery is blasted and can be caused hardly imaginable consequence in inflammable and explosive place.
Chinese patent CN1016454496A discloses a kind of battery case burst disk, on burst disk, processes impression, and the impression part is relatively weaker, and gas pressure arrives and to a certain degree can impression be broken through, and reduces pressure.It is similar to process the method for suppressing trace on this method and the conventional batteries case, exists the degree of depth of impression to be difficult to control, does not have shortcomings such as regulating cell box internal pressure function, and explosion-proof reliability is difficult to guarantee that the scope of application is less.
The utility model content
In order to overcome the above-mentioned defective that prior art exists, the utility model provides a kind of functional reliability high, battery car automatic Regulation explosion-protection equipment applied widely.
The technical scheme of the utility model is: it comprises housing, and said housing flexibly connects with the battery case that storage battery is housed, and the housing top is provided with cover plate, and cover plate is provided with exhaust outlet; Be provided with slide block in the housing, slide block is with enclosure interior cavity separated into two parts, and a part is the balancing gate pit; With the battery case internal communication, another part is the spring installation room, is provided with spring in the spring installation room; Spring one end is connected with inner walls, and the other end is connected with slide block, and slide block one side is provided with the guide vane end stop that places in the balancing gate pit.
Further, said slide block is the I shape slide block.
Further, said housing flexibly connects through connecting thread pipe and the battery case that storage battery is housed.
Further, the preferred 45mm of the diameter of said connecting thread pipe.
Further, said inner walls is provided with the spring mounting hole I, and slide block is provided with the spring mounting hole II, and spring one end links to each other with inner walls through the spring mounting hole I, and the spring other end links to each other with slide block through the spring mounting hole II.
Further, said spring mounting hole I and spring mounting hole II are located on the same horizontal plane, and it is smooth and easy to be beneficial to guarantee that slide block moves.

Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
With reference to accompanying drawing, present embodiment comprises housing 1, and housing 1 flexibly connects through connecting thread pipe 2 and the battery case (not shown) that storage battery is housed; Housing 1 top is provided with cover plate 3, and cover plate 3 is provided with exhaust outlet 10, is provided with slide block 5 in the housing 3; Slide block 5 is the I shape slide block, and slide block 5 is with housing 1 internal cavities separated into two parts, and a part is balancing gate pit 4; Balancing gate pit 4 is through connecting thread pipe 2 and battery case internal communication, and another part is a spring installation room 12, is provided with spring 9 in the spring installation room 12; Spring 9 one ends are connected with housing 1 inwall through spring mounting hole I 8; The other end is connected with slide block 5 through spring mounting hole II 7, and spring mounting hole I 8 is located on the same horizontal plane with spring mounting hole II 7, and it is smooth and easy to be beneficial to guarantee that slide block moves; Slide block 5 one sides are provided with the guide vane end stop 6 that places balancing gate pit 4 indoor, and slide block 5 belows are provided with slide block guide rail 11, and slide block guide rail 11 is connected with housing 1 bottom.
The diameter of connecting thread pipe is 45mm.
The utility model is according to the pretightning force of the specification setting spring 9 of battery pack.Storage battery produces a large amount of gases in the battery case in charge and discharge process, and it is indoor that gas gets into balancing gate pit 4; When the gas in the balancing gate pit 4 sharply increased, pressure in the balancing gate pit rose, when pressure during greater than the pretightning force of spring 9; Slide block 5 to spring installation room 12 1 side shiftings, moves to a certain degree under the effect of spring 9; Balancing gate pit 4 connects with exhaust outlet 10, and gas is discharged through exhaust outlet 10.Along with the continuous discharge of gas, the pressure in the balancing gate pit 4 reduce, when pressure during less than the pretightning force of spring 9; Slide block 5 resets under the effect of spring 9, and steam vent 10 is closed, and realizes the automatic Regulation process thus; Make the battery case internal pressure be in safe range, play explosion-proof effect.
