The air entering the interior of the protective shell 2 through the air inlet of the protective shell 2 moves downwards along the gap between the heat absorbing part 301 and the protective shell 2 and blows to the arc-shaped screen 15, after the air blows to the air screen, the air is dispersed under the action of the air screen and blows to the connecting plate 302, the connecting plate 302 is provided with holes, the air flows to other parts of the heat absorbing part 301 through the holes, thereby radiating the heat of the other parts, the arc-shaped screen 15 is provided with a plurality of holes, the air can be dispersed more, more heat is absorbed, and finally the air flows into the ventilation hood 6 through the convergence of the support screen and is finally exhausted by the exhaust fan.
The temperature sensor 5 on the heat absorbing portion 301 can detect the temperature inside the protective housing 2 in real time, so that the new energy battery 4 can work in an environment with proper temperature, and heat dissipation of the new energy battery 4 can be achieved through the structure.
Because the inside and the outside of the protecting shell 2 are communicated, when the new energy battery 4 burns, the flame can leak along the air inlet or the air outlet, and can influence other new energy batteries 4, so that the whole battery pack is scrapped, and even equipment such as a battery car, an automobile and the like can burn, thereby causing larger property loss.
When the temperature sensor 5 detects that the temperature exceeds the threshold value, the electric push rod on the ventilation hood 6 is started to move the grid baffle 7 in a direction away from the protective shell 2, so that the grid baffle 7 is separated from the sealing plate 9, at the moment, the sealing plate 9 can rapidly move downwards under the action of the second elastic piece 12, meanwhile, the movable pore plate 8 is moved through the connecting rope, the second elastic piece 12 is stretched, the air inlet of the protective shell 2 is sealed by the movable pore plate 8 while the air outlet of the protective shell 2 is sealed by the sealing plate 9, and the new energy battery 4 is sealed inside the protective shell 2, so that the new energy battery 4 is separated from the external connection, and the fire of the new energy battery 4 is reduced, so that the damage is prevented from being further expanded.
In addition, when the movable pore plate 8 moves, the cutting edge 13 on the movable pore plate cuts off the wires clamped in the wire clamping groove 14, so that the wires are prevented from burning under the action of the new energy batteries 4, and further other new energy batteries 4 are ignited.
After the sealing plate 9 moves downwards to seal the air outlet of the protective shell 2, the pressing plate 22 receives the extrusion of the sealing plate 9 and drives the extrusion column 23 to move downwards, so that hydraulic oil in the cylinder 25 is filled into the oil storage box 18, the two piston plates 20 move, the clamping teeth 21 on the clamping plate 19 are separated from the protective shell 2, the protective shell 2 and the mounting base 1 are in a pre-unlocking state, the clamping hoop 28 is unlocked, the connecting rod 29 is unlocked, the new energy battery damaged by combustion can be detached, and the connecting rod 29 and the second handle can be directly sheared in an emergency.
In addition, in order to facilitate the process of taking out the protecting shell 2, the clamping plate 19 does not obstruct the protecting shell 2, so long as the closing plate 9 is always in contact with the pressing plate 22, only the second elastic piece 12 is in a compressed state at any time, and only under the suspension effect of the protecting shell 2, the second elastic piece 12 is in a state without elasticity.
In sum, through movable clamping plate 19, closing plate 9, first elastic component 11 and second elastic component 12 can realize closing and opening simultaneously of protective housing 2 air intake and air outlet to can dispel the heat when new forms of energy battery 4 normal operating, under the state of burning, self-closing, and make the battery of burning damage be in the state of quick detach simultaneously, be convenient for in time reduce the loss, prevent further expansion damage.
