[0033] Further, a crank is arranged on one side of the screw rod 18, and the other side of the crank is provided with a rotating handle, which can rotate the screw rod 18 through the rotating handle.

[0034] Working principle: when the device is used for vegetables, the temperature sensor 6 can detect the temperature in the shed body 1. When the temperature in the shed body 1 is too high, the motor 19 can be started to rotate, which can drive the connecting block 20 to rotate, and then the connecting block 20 drives the docking block 21 to rotate, which can drive the rotating rod 5 to rotate, and then the rotating rod 5 drives the two groups of winding wheels 3 to rotate, which can wind the pull rope 13. The guide wheel guides the pull rope 13, so that the pull rope 13 can pull the two groups of baffles 14 to move upward to open the ventilation opening 15. According to the temperature in the shed body 1, the opening amplitude of the ventilation opening 15 can be adjusted, so that the temperature in the shed body 1 can be controlled to provide a good temperature environment for the vegetables.

[0035] When encountering special weather such as rainy days, the shed body 1 cannot be ventilated according to the temperature. At this time, the staff can manually rotate the screw rod 18 to drive the motor 19 to move to one side to release the clamping of the connecting block 20 and the docking block 21. At this time, the staff can manually adjust the opening amplitude of the baffle 14 by rotating the rotating rod 5 through the rotating handle. When adjusted to the appropriate position, the bolt 23 can be inserted into the insertion hole 22 to fix the baffle 14, which improves the flexibility of the temperature control of the shed body 1.

[0036] When the shed body 1 is not ventilated, the humidity in the shed body 1 will quickly rise. At this time, the fan 9 can be started to run, which can suck the air flow in the shed body 1 into the dehumidification bin 10. The dehumidification bin 10 can absorb the moisture in the air through the dehumidification plate 11. The dehumidified air can be guided to the spray pipe 12 through the connecting pipe 7, and then sprayed out from both ends, which ensures the air flow in the shed body 1 and makes the temperature more uniform.
