s2, when the phase change material in the phase change energy storage module absorbs heat, the heat absorption capacity detection mechanism built in the phase change energy storage module works synchronously, the air in the piston cavity 10 in the heat absorption capacity detection mechanism is heated to expand gradually in the process of gradually increasing the temperature of the phase change energy storage module, the expanded air pushes the piston 11 and the piston rod 12 to move outwards slowly, the piston rod 12 drives the tamping rod 13 connected with the piston rod to move along the central axis direction of the communicating hole 23, when the amount of heat absorbed by the phase change material in the phase change energy storage module gradually reaches a limit value, as shown in fig. 7, the tamper rod 13 passes through the communication hole 23 and is inserted into the spherical groove 22, therefore, the universal rolling ball 21 in the spherical groove 22 is ejected out, the universal rolling ball 21 drives the first magnetic suction block 20 to move upwards through the movable rod 19 connected with the universal rolling ball 21, and the spherical groove 22 loses the limiting effect on the universal rolling ball 21;
meanwhile, as the motor drives the second swing rod 25 and the second magnetic suction block 26 to do circular motion, when the second magnetic suction block 26 moves to the position where the universal rolling ball 21 is located, the second magnetic suction block 26 and the first magnetic suction block 20 above the universal rolling ball 21 attract each other, so that the second magnetic suction block 26 can drive the first magnetic suction block 20 to do circular motion synchronously through magnetic suction, the first magnetic suction block 20 drives the first swing rod 18 and the universal rolling ball 21 to do circular motion synchronously through the movable rod 19, and further the first swing rod 18 drives the fourth magnetic suction block 28 to do circular motion synchronously, so that the fourth magnetic suction block 28 does not generate mutual repulsion with the previous third magnetic suction block 33, the third magnetic suction block 33 drives the pressing plate 30 to reset under the action of the telescopic mechanism, so that the pressing plate 30 does not press the corresponding self-resetting switch 32 any more, and the self-resetting switch 32 disconnects the power supply line between the electric heating module and the solar power generation device, the electric heating module does not heat the phase change energy storage module any more.
S3, when the universal rolling ball 21 moves to the next spherical recess 22 in the process of circular movement, the universal rolling ball 21 falls into the spherical recess 22 under the action of gravity, at this time, the new spherical recess 22 has a limit function on the universal rolling ball 21 again, when the universal rolling ball 21 falls into the spherical recess 22, the universal rolling ball 21 drives the first magnetic attraction block 20 to move downwards through the movable rod 19, so that the distance between the first magnetic attraction block 20 and the second magnetic attraction block 26 is increased, the attraction force between the two is weakened, the second magnetic attraction block 26 is difficult to continue to drive the second magnetic attraction block 26 to move synchronously through the magnetic attraction force, at the same time, the first swing rod 18 stops moving synchronously, the fourth magnetic attraction block 28 on the first swing rod 18 moves to the vicinity of the phase change energy storage module at the position of the spherical recess 22, and the third magnetic attraction blocks 33 on the self-reset switch 32 corresponding to the phase change energy storage module are mutually arranged, the third magnetic suction module 33 pushes the pressing plate 30 to press the corresponding self-reset switch 32 under the action of the repulsive force, so that the self-reset switch 32 is connected with a power supply line between the corresponding electric heating module and the solar power generation device, the solar power generation device supplies power to the electric heating module through the power supply line, the electric heating module heats the phase change energy storage module, and then the process of the step 2 is repeated for multiple times until all the phase change energy storage modules fully absorb heat.
