When a sunny day is encountered, the electromagnet 41 is electrified to generate electromagnetism, so that the electromagnet 41 and the permanent magnet 42 are in a repulsive state again, the electromagnet 41 and the device thereon move downwards, the first extension spring 43 is extended accordingly, the wedge-shaped frame 47 pushes the double-sided wedge 48 and the device thereon to move, the first return spring 49 is compressed accordingly, the shifting block 73 pushes the slotted fixing shaft 412 and the device thereon to move towards the direction close to the limiting support frame 85, one second return spring 411 is extended accordingly, the other second return spring 411 is compressed accordingly, so that the slotted fixing shaft 412 does not block the limiting round rod 66 any more, the limiting round rod 66 is reset accordingly under the resetting action of the fifth return spring 67, the four-corner sliding block 62 and the device thereon move downwards under the resetting action of the fourth return spring 64, and are matched with the open-close frame 63 and the device thereon through the four-corner sliding block 62, the opening and closing frame 63 and the upper device thereof are reset, so that the waterproof cloth on the opening and closing frame 63 is folded, the waterproof cloth on the opening and closing frame 63 is prevented from being damaged due to long-time insolation, and the effect of automatically folding the waterproof cloth on the opening and closing frame 63 is achieved. When the wedge bracket 47 moves to the initial position, the double-sided wedge 48 and the device thereon are then restored by the restoring action of the first restoring spring 49.

Meanwhile, the first gear rack 44 drives the first gear 46 and the device thereon to rotate clockwise, the second gear rack 53 drives the second gear rack 54 and the device thereon to reset under the action of the connecting rod 52, the first triangular block 82 pushes the opening limiting block 415 and the device thereon to reset to the initial position in the process, the second extension spring 414 is extended accordingly, the second triangular block 83 contacts with the third triangular block 86, the third triangular block 86 extrudes the second triangular block 83 and the device thereon to move, the sixth return spring 84 is compressed accordingly, so that the first triangular block 82 is separated from the opening limiting block 415, then the first triangular block 82 is separated from the third triangular block 86, the third triangular block 86 is reset under the reset action of the sixth return spring 84, then the limiting frame 410 is clamped on the opening limiting block 415 again, when the four-corner sliding block 62 and the device thereon are reset, the slotted sliding shaft 413 pushes the shifting block 73 to swing, the first torsion spring 74 is compressed accordingly, and the slotted fixing shaft 412 and the device thereon are reset under the reset action of the second reset spring 411 accordingly.
