In the specific working process of the invention, after the battery in the battery box 1 is intelligently and long-time overheat-tested, the temperature on the battery box 1 can be continuously raised, thus the battery is easy to be damaged and the normal work of the subsequent battery is influenced, after the battery box 1 is heated, the heat can be transferred to the fixed box 36, because the heat insulation plate 35 is arranged in the fixed box 36 and the ventilation channel 81 is arranged at the bottom of the fixed box 36, the air pressure temperature at the bottom of the heat insulation plate 35 is the same as the external environment, the air pressure at the top of the heat insulation plate 35 can be heated and expanded due to the heat transfer, the heat insulation plate 35 can slide downwards due to the expansion of hot air, the heat insulation plate 35 can drive the pull rod 34 to slide downwards, because the pull rod 34 penetrates and slides at the bottom of the fixed box 36, the pull rod 34 can only vertically slide, so that one end of the pull rod 34 far away from the heat insulation plate 35 can drive the slide column 33 to move downwards, the sliding column 33 can move vertically downwards to drive the rotating plate 32 to move downwards, and in the descending process of the rotating plate 32, because the top end only moves vertically, the rotating plate 32 can rotate, the bottom of the rotating plate 32 can push the insulating plate 31 to slide towards the terminal 2 along the limiting rod 4, the insulating plate 31 can block the outside of the terminal 2, so that the electric connection of the terminal 2 is cut off, and further the battery in the battery box 1 stops working, the battery can be protected in time when the battery is overheated, otherwise, when the temperature is adjusted back, the heat insulation plate 35 moves upwards due to the elasticity of the elastic element, the heat insulation plate 35 can pull one end of the pull rod 34 to move upwards, the other end of the pull rod 34 can push the sliding column 33 to move vertically upwards, the sliding column 33 can pull the top of the rotating plate 32 to move upwards, so that the rotating plate 32 can rotate correspondingly, so that the rotating plate 32 pulls the insulating plate 31 to slide along the limiting rod 4 towards the sliding column 33, and the insulating plate 31 is separated from the terminal 2;
by providing the automatic ejecting device, when the thermal insulation board 35 slides downwards due to thermal compression expansion, the thermal insulation board 35 can drive one end of the lever board 61 to move downwards, so that the lever board 61 rotates and slides anticlockwise around the rotating column 62 as a circle center, so that the other end of the lever board 61 can jack up the connecting long rod 63, so that the connecting long rod 63 can push the jack-up block 64 upwards, the jack-up block 64 can jack up the battery upwards, so that the direct connection between the battery and the battery box 1 is cut off, thereby preventing the battery box 1 from transferring heat reversely to the battery to cause secondary damage, meanwhile, when the jack-up block 64 is pushed upwards by the connecting long rod 63, the top of the jack-up block 64 can drive the adapting bottom board 71 to move upwards, the adapting bottom board 71 can drive the lifting rod 72 to move upwards together with following, the top of the lifting rod 72 can drive the lifting rod 73 to move upwards, until the lifting rod 72 pushes the rotating part at the bottom of the protection board 73 to leave the top of the limit block 74, the protective plate 73 can rotate anticlockwise due to the pulling force of the metal elastic plate 75, so that buffering elastic force can be effectively provided for jacking the battery, and the battery can be prevented from flying out and being damaged due to overlarge jacking force;
by arranging the opening and closing ventilation device, the air pressure temperature at the bottom of the heat insulation plate 35 can be kept to be the same as the temperature of the external environment when the air duct 81 normally works, when the battery is detected to be overheated, the heat insulation plate 35 slides downwards due to the expansion of air pressure due to heating, the heat insulation plate 35 can drive the blocking piece 84 to move downwards along with the movement, the blocking piece 84 can gradually block the dust-proof plate 82 and the air duct 81 downwards, the ventilation effect of the air duct 81 is closed, the heat insulation plate 35 can be always positioned at the bottom of the fixed box 36 to carry out alarm operation, so that the position of the heat insulation plate 35 is always positioned at the bottom of the fixed box 36, finally, the continuous alarm operation can be kept, the battery can be always kept in a disconnected state, the timeliness of the alarm warning effect is improved, meanwhile, the blocking piece 84 can be contacted with the inclined plane of the push plate 83 and slide on the inclined plane of the push plate 83 when moving downwards, the blocking piece 84 generates transverse thrust to the dust-proof plate 82 when the inclined plane of the push plate 83 vertically moves downwards, this thrust extrusion dust guard 82 for dust guard 82 outwards slides along ventiduct 81, and when the temperature reduced got back to the temperature of normal during operation, initial position just can be got back to the heat insulating board 35 because the elasticity rebound of shell fragment, and dust guard 82 just can get back to initial position because the elastic action of shell fragment this moment makes dust guard 82 can utilize the sliding force to reach the effect that oneself removed dust at gliding in-process.
