3: chain 40 is extended while elevator block 39 is moving downward so that fixed plate 76 and the device to the right of it move to the left to allow room for open cover block 74, after which motor 49 is quickly reversed so that centrifugal wheel 62 is quickly reversed, under the action of centrifugal force, the centrifugal block 58 enters the limit cavity 56 to drive the pull rope 45 to be tensioned, the fixture block 42 moves leftwards and resets, the lifting block 39 loses the limitation of upward movement, the motor 49 drives the transmission shaft 61 and the lifting gear 48 to rotate reversely, the lifting block 39, the rotating gear 78 and the cover opening block 74 are moved upwards to take out the cover, the lifting block 39 moves upwards, the chain 40 is loosened, the fixing plate 76 and the connecting pipe 75 move rightwards under the action of the fixing spring 65, the rotating gear 78 moves upwards, the rope 20 and the connecting rope 24 are pulled, the slide plate 23 moves upwards to drive the upper side mechanism to move upwards together, and the turning block 37 contacts the water discharging screw;

4: starting the torsion electromagnet 26, attracting the torsion magnet 26, driving the water changing plate 27 to move downwards, pulling the tension rope 28, driving the water changing rope winding wheel 29, the water changing shaft 30 and the torsion chain wheel 31 to rotate for half a circle, driving the rotation chain wheel 34, the rotation shaft 35 and the torsion block 37 to rotate for half a circle, opening the water discharging screw, catching the water flow by the water receiving funnel 15, finally entering the outflow cavity 22 through the overflow cavity 19 for water discharging, closing the torsion electromagnet 26 after the cooling liquid is completely discharged, rotating and resetting the water changing rope winding wheel 29 under the action of the torsion spring 18, driving the water changing shaft 30, the torsion chain wheel 31, the rotation chain wheel 34, the rotation shaft 35 and the torsion block 37 to rotate and reset, and screwing the water discharging screw on newly, then starting the water blocking electromagnet 12, attracting the water blocking magnet 13, moving the water blocking 86 leftwards, so that the cooling liquid in the water changing plate 46 finally flows into the radiator through the connecting pipe 75, when the sensor 81 detects that the magnetic pole of the water blocking electromagnet 12 is reversed after enough cooling liquid flows in, the water blocking block 86 moves rightwards to reset, and the cooling liquid flows down;

5: then the motor 49 is rotated to drive the transmission shaft 51 and the lifting gear 48 to rotate forward, the lifting blocks 39, 78 and 74 are driven to move downwards, and since the cap has been lowered a distance after a period of time, the cap is allowed to come into new contact with the threads on the heat sink, when the cover reaches the lowest position, slowly reversing the motor 49 to drive the transmission shaft 61, the transmission belt pulley 50, the driven belt pulley 51, the driven shaft 52, the driven bevel gear 53, the rotating bevel gear 54, the rotating shaft 55 and the connecting gear 83 to reversely rotate, drive the rotating gear 78 and the cover opening block 74 to reversely rotate, screwing the cover on the cover, then accelerating the rotating speed, so that the centrifugal block 58 enters the limit cavity 56 under the action of centrifugal force, the centrifugal wheel 62 drives the rolling wheel 63 to rotate reversely, the pull rope 45 is reset by the left movement of the tension latch 42, the lifting gear 48 returns the lifting block 39 to move upwards due to the loss of restraint, and the vehicle is moved out of the machine at the same time.
