s2: the bottom plate (3) drives the insertion rod (6) to be inserted into the connecting block (7), the insertion rod (6) continuously enters the connecting groove (8) to be contacted with the clamping ball (11), the top end of the clamping ball (11) is smooth and smooth, the clamping ball (11) moves towards two sides and is abutted against the inner wall of the connecting groove (8), along with the continuous abutting of the insertion rod (6) with the clamping ball (11), the fixed clamping groove (9) is driven to move upwards through the abutting of the clamping ball (11) and the inner wall of the clamping hole (10) to compress the spring (13);
s3: when the fixed clamping groove (9) moves upwards, the inserted bar (6) continues to move upwards, when the opening grooves on the surfaces of the clamping ball (11) and the inserted bar (6) are positioned on the same plane, the clamping ball (11) moves towards the inside of the groove, at the moment, the clamping ball (11) is not abutted with the inner wall of the connecting groove (8), the fixed clamping groove (9) is driven to reset by the resilience force of the spring (13), the clamping ball (11) is driven by the inner wall of the clamping hole (10) to move downwards, the clamping ball (11) is abutted with the inner wall of the connecting groove (8), and the clamping ball (11) is positioned on the inner wall of the opening groove and abutted with each other, so that the inserted bar (6) is clamped and fixed;
step two:
s1: when a user starts the automobile, the battery body (4) starts to work and releases heat, air enters the air inlet (21) at a high speed in the automobile running process, enters the air guide frame (19) through the air guide pipe (20) and is contacted with the fan (22);
s2: the wind power pushes the fan (22) to rotate, the high-speed wind power is blocked by the fan (22), so that the wind power is reduced, after the wind power enters the interior of the heat dissipation bin (14), the wind power is contacted with the heat dissipation fins (15) and the heat conduction copper tube (17), the heat dissipation fins (15) and the heat conduction plate (16) absorb heat emitted by the battery body (4) during working, and then the heat on the heat dissipation fins (15) is absorbed by the heat conduction copper tube (17);
s3: after the cooling liquid in the heat conduction copper pipe (17) absorbs heat, the micro water pump (18) drives the cooling liquid to flow in the heat conduction copper pipe (17) to complete the circulation heat absorption, and the cold air entering through the air inlet (21) cools the cooling liquid in the heat conduction copper pipe (17);
step three:
s1: one hundred liters of hundred-percent ethanol is stored in the liquid tank (23), the ethanol is adsorbed by a sponge (25) in a connecting pipe (24), the ethanol adsorbed by the sponge (25) is continuously conveyed to the interior of the heat dissipation bin (14), and the ethanol continuously overflows from the surface of the heat conduction copper pipe (17) through the sponge (25) wrapping the heat conduction copper pipe (17);
s2: the ethanol is quickly evaporated under the action of the wind power conveyed into the heat dissipation bin (14) by the secondary air inlet (21), and the heat of the heat conduction copper pipe (17) can be quickly absorbed through the evaporated ethanol;
s3: the fan (22) blocks high-speed wind power, so that the wind power is reduced, the wind power is prevented from being high, the ethanol is quickly evaporated, and the speed of the sponge (25) for absorbing the ethanol is approximately the same as the speed of the ethanol for evaporating;
step four:
s1: when maintenance is needed, the bottom plate (3) is pushed upwards, the clamping ball (11) is pushed to move upwards through the inner wall of the opening groove of the inserted rod (6), the clamping ball (11) is abutted against the inner wall of the clamping hole (10), the fixed clamping groove (9) is driven to move upwards, and the spring (13) is compressed;
s2: card ball (11) constantly rises, and the interval of spread groove (8) both sides inner wall is bigger and bigger for card ball (11) no longer contradicts with spread groove (8) inner wall, thereby is promoted to both sides by inserted bar (6), leaves inside the open groove, then pulls bottom plate (3) downwards, makes the open groove remove to the below of card ball (11), thereby connecting block (7) can be taken out in inserted bar (6), takes off battery body (4).
