In a high-temperature environment, such as summer, the combined inner bin cover 2 is gradually moved out of the combined outer bin cover 1, and as shown in fig. 4 and 5, the associated vertical pages 6 are pulled and pulled through the fixed wall nails 9, so that after the combined inner bin cover 2 and the combined outer bin cover 1 are separated in place, the battery clusters 4 are also pulled away from each other, and the distance is increased so as to facilitate air flow cooling.
When the temperature sensor arranged in the battery cluster 4 detects that one battery cluster 4 is abnormally heated and exceeds a preset temperature, the feedback signal enables the independent protection storage battery 121 to supply power to the electric control air valve 120, the electric control air valve 120 is opened, and compressed flame-retardant gas in the compressed gas cylinder 118 is input into the release air pipe 105 through the gas leakage pipe 119.
As shown in fig. 14, the gas drives the execution baffle 106 to move axially, the execution baffle 106 drives the locking pin shaft 109 to move, so that the locking pin shaft 109 is pulled out from the frame door lock hole 107 and the screw sleeve lock hole 108, the split screw sleeve 104 can move relatively relative to the frame door fixing piece 103, the execution baffle 106 pushes the right-angle pushing piece 115 to push the right-angle pushing piece 115 and the pre-closing flashboard 114 to move, the pre-closing flashboard 114 seals the breathing bottom hole 116, after the breathing bottom hole 116 is sealed, the sealing space formed by combining the combined inner bin cover 2 and the combined outer bin cover 1 is in a sealing state, after flame-retardant gas is sprayed out through the release gas pipe 105, the flame-retardant gas is filled in the combined outer bin cover 1 and the combined inner bin cover 2, so that the gas pressure in the combined outer bin cover 1 and the combined inner bin cover 2 is increased, the combined inner bin cover 2 is pushed to move relative to the combined outer bin cover 1 through the gas pressure, the battery clusters 4 are separated from each other, and the distance is increased, so that the influence between adjacent battery clusters 4 is reduced. And through the fire-retardant gas filling in the combination inner bin cover 2 and the combination outer bin cover 1, the combustion-supporting gas proportion in the combination inner bin cover 2 and the combination outer bin cover 1 can be reduced, the safety is improved, meanwhile, according to the first law of thermodynamics, after the compressed gas is released, the compressed gas expands to do work outwards, the internal energy per se is reduced, the temperature is reduced, and therefore the space in the combination inner bin cover 2 and the combination outer bin cover 1 can be rapidly cooled, and abnormal temperature rise of the battery cluster 4 is restrained. The above-mentioned through the removal of the interior storehouse cover 2 of pneumatic drive combination, need not to pass through action motor 101 drive again, can avoid the outage influence of battery cluster 4, action motor 101 is high-power consumption equipment, needs to connect power supply, when battery cluster 4 breaks down, is difficult to guarantee to the power supply stability to action motor 101.
If the combined inner bin cover 2 and the combined outer bin cover 1 are already in a separated state in a high-temperature environment in summer, the distance between the battery clusters 4 is moved to the maximum, and when abnormal temperature rise of one battery cluster 4 is detected at this time, the compressed air bottle 118 is controlled to release air, as shown in fig. 11, at this time, the right-angle pushing piece 115 is separated from the release air tube 105, the execution baffle 106 does not push the right-angle pushing piece 115 to move any more, so that the breathing bottom hole 116 can be kept open, the released flame-retardant air enters the combined inner bin cover 2 and the combined outer bin cover 1, and the air in the combined inner bin cover 2 and the combined outer bin cover 1 is extruded and discharged through the breathing bottom hole 116, and meanwhile, the temperature is rapidly reduced and protected.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
