[0029] In this embodiment, the connection between the support 18 and the winding roller 19 is equipped with a spiral spring, and the two ends of the spiral spring are connected with the support 18 and the winding roller 19 respectively. The spiral spring provides power to the winding roller 19 (such as a tape measure), when the screw block 22 moves downward to unfold the waterproof cloth 20, the winding roller 19 rotates to make the spiral spring tighten and compress potential energy, when the screw block 22 moves upward, the spiral spring releases potential energy to provide power for the winding roller 19, so that the winding roller 19 reversely rotates to wind the waterproof cloth 20.

[0030] In this embodiment, the battery 6 is connected with the step-down module 7, the step-down module 7 is connected with the single-chip microcomputer 8 and the rain and snow sensor 4, the 12V voltage of the battery 6 is reduced to 5V voltage through the step-down module 7 (such as LM2596 type), to supply power for the single-chip microcomputer 8 and the rain and snow sensor 4.

[0031] In the embodiment, the rain and snow sensor 4 is connected with the single-chip microcomputer 8, and the surface of the rain and snow sensor 4 usually adopts a capacitive sensing or resistance change principle.

The single-chip microcomputer 8 is connected with the relay module 9, and a 5V signal of the single-chip microcomputer 8 drives an electromagnetic coil in the relay module 9 to generate a magnetic field to attract a contact point. The relay module 9 is connected with the motor 10, and when the contact point of the relay module 9 is closed, 12V voltage of the battery 6 directly supplies power to the motor 10. When the contact point is disconnected, the motor 10 is powered off.

[0033] Principle of the utility model:

[0034] When the rain is heavy, the rain and snow sensor 4 is triggered by rainwater, and outputs a signal to the single-chip microcomputer 8. A high level signal is outputted from the single-chip microcomputer 8 to the relay module 9 to make the relay module 9 energized and the contact point closed. At this time, the motor 10 is powered on and runs in reverse (the running direction can be set by the single-chip microcomputer 8 and the motor 10 with an encoder). The motor 10 drives the bevel gear one 12 to rotate, the bevel gear one 12 drives the four bevel gear two 13 to rotate simultaneously, the bevel gear two 13 drives the shaft rod 16 to rotate to make the bevel gear four 17 rotate, the bevel gear four 17 drives the bevel gear three 15 to rotate to make the four lead screws 14 rotate simultaneously. At this time, the threaded block 22 moves downward along the lead screw 14, the threaded block 22 drives the cross rod 21 to move downward to unroll the tarpaulin 20 from the winding roller 19, so that the gap between the box door 2 and the top of the box body 1 is shielded. When the rain stops, the rain and snow sensor 4 is triggered, and a signal is transmitted to the single-chip microcomputer 8. A high level signal is outputted from the single-chip microcomputer 8 to the relay module 9 to make the relay module 9 energized and the contact point closed. At this time, the motor 10 is powered on and runs in reverse (the running direction can be set by the single-chip microcomputer 8 and the motor 10 with an encoder). The motor 10 drives the bevel gear one 12 to rotate, the bevel gear one 12 drives the four bevel gear two 13 to rotate simultaneously, the bevel gear two 13 drives the shaft rod 16 to rotate to make the bevel gear four 17 rotate, the bevel gear four 17 drives the bevel gear three 15 to rotate to make the four lead screws 14 rotate simultaneously. At this time, the threaded block 22 moves upward along the lead screw 14, the threaded block 22 drives the cross rod 21 to move upward, and the winding roller 19 is driven to rotate in reverse by the elastic force of the spiral spring to wind the tarpaulin 20, so that the tarpaulin 20 is stored.
