[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The automatic opening and closing device of the granary vent is provided with a vent component group. The current granary vent position lacks an automatic opening and closing structure. In actual use, the vent cannot be ventilated in time according to the change of gas concentration in the granary, and the gas concentration cannot be ensured to be within an appropriate range. Manual opening and closing are prone to be untimely. In the corresponding designed vent component group, the gas concentration detector installed inside the granary will send information to the main control board through a signal line when it detects that the gas concentration is abnormal and ventilation is required. The main control board will control the contraction of the two cylinder parts through the signal line after receiving the signal.

At this time, the vent of the granary is in a closed state, and gas-controlled grain storage is carried out. The design of this vent component group can automatically open or close the ventilation according to the judgment of the gas concentration by the gas concentration detector inside the granary. Compared with the current manual opening and closing method, the operation is faster and ventilation or closing can be carried out in time. The system can monitor the changes in gas concentration in the granary in real time to ensure a rapid response to abnormal situations.

When the current granary vent is opened for ventilation, it is necessary to prevent insects from entering the granary through the vent. In the corresponding designed mosquito-proof component group, frame plate component 1 is connected to one side of the ventilation main cylinder. If external air needs to enter the granary through the vent component group, it needs to pass through the mosquito-proof component group.

[0027] Working principle: The current granary vents lack an automatic opening and closing structure. In actual use, the vents cannot be ventilated in time according to changes in the gas concentration in the granary, and cannot ensure that the gas concentration is within an appropriate range. Manual opening and closing are prone to being untimely. In the corresponding designed vent component group 01, the gas concentration detector installed inside the granary will send information to the main control board 12 through a signal line when it detects that the gas concentration is abnormal and ventilation is required. The main control board 12 receives the signal and controls the two cylinder parts 13 to contract through the signal line. The contracted cylinder parts 13 will connect the air grooves on the regulating air plate 15 with the air grooves on the rear air plate 16 and the front air plate 17. External gas can pass through the air grooves into the granary, and the fan assembly 110 installed inside the rear cylinder 19 also wants to be opened.

The staggered rear air plate 16, the adjusting air plate 15 and the front air plate 17 will form a sealing structure to block the gas from passing through the ventilation main cylinder 11. At this time, the vent of the granary is in a closed state, and gas-controlled grain storage is carried out. The design of this vent component group 01 can automatically open or close the ventilation according to the judgment of the gas concentration by the gas concentration detector inside the granary. Compared with the current manual opening and closing method, the operation is faster and ventilation or closing can be carried out in time. The system can monitor the changes in gas concentration in the granary in real time to ensure a rapid response to abnormal situations. When the current granary vents are opened for ventilation, it is necessary to prevent insects from entering the granary through the vents. In the correspondingly designed mosquito-proof component group 02, the frame plate 21 is connected to one side of the ventilation main cylinder 11. If external air needs to enter the granary through the vent component group 01, it needs to pass through the mosquito-proof component group 02.
