9. The solar charging and discharging controller as claimed in any one of claims 1-8, wherein the controller is used by the following method:

s1, when the top of the cable is connected, a motor (9) rotates to drive a rolling wheel (10) to rotate, the rolling wheel (10) rotates to wind a pull rope (11), the pull rope (11) pulls a piston (7) to move downwards, gas in a fixed block (5) is extruded by the piston (7) to enter a sealing bag (4), the expanded sealing bag (4) is tightly attached to the outer wall of the cable, external water vapor and dust are prevented from invading a wiring port (2), the wiring port (2) is protected, a spring (6) of the spring is used for restoring the piston (7), and the possibility of damage of the wiring port (2) is greatly reduced by the structure;

s2, the mounting plate (12) is mounted on a mounting component through a bolt, the second spring (19) of the mounting plate tightly presses the touch plate (20) on a mounting surface, so that upward force is applied to the mounting plate (12), the bolt is kept tight and is not easy to loosen, the pressure sensor (21) senses pressure in real time, when the pressure is reduced, the second motor (17) rotates to drive the worm (15) to rotate, the worm (15) rotates to drive the gear (16) to rotate, the gear (16) rotates to drive the toothed plate (18) to move, the toothed plate (18) moves to drive the moving plate (14) to move, the moving plate (14) moves to move the second spring (19) downwards, and accordingly the force applied to the touch plate (20) is increased, the mounting plate (12) is applied with the upward force, the bolt does not need to be prevented from loosening by a spring washer, and the elastic force can be automatically increased when the elastic force is small, so that the bolt is not easy to loosen;

s3, the heat conducting fins (24) guide the heat in the device body (1) to the heat conducting plate (23), the third motor (26) rotates to drive the fan blades (27) to rotate, the fan blades (27) rotate to suck the device body (1) from the air inlet (29) and discharge the heat from the air outlet (28), so that the air flow exchange in the heat radiating grooves (22) is accelerated, the heat is led out to the outside by the air flow, and in the structure, the water vapor can not enter the device body (1) any more during heat radiation, so that the water vapor is prevented from entering the device body (1), parts in the air are prevented from being damaged easily, and the heat radiating effect is improved;

s4, foam extinguishing agent is stored in the storage tank (32), external air is filled into the storage tank (32) through the air pump (36), the storage tank (32) is enabled to keep a high-pressure state, when the temperature sensor (31) detects that the temperature of the device body (1) is abnormal, the four-motor (37) rotates to drive the transmission teeth (38) to rotate, the transmission teeth (38) rotate to drive the transmission plate (42) to move, the transmission plate (42) moves to drive the pressing plate (40) to move, the pressing plate (40) moves upwards to enable the baffle (34) to be opened, so that the foam extinguishing agent on the top of the baffle (34) is sprayed out from the spray holes (33), the foam extinguishing agent is sprayed on the surface of the device body (1), and therefore, the diffusion of fire is inhibited, and the safety of the foam extinguishing agent is improved.
