[0039] like Figure 1-6 As shown, the utility model provides an automatic airtight system for air film structure, comprising: a pressure space 1, the pressure space 1 is provided with a vent 6 connected to the outside; a seal 2 and an automatic traction device 3, the seal 2 blocks the vent 6, and the seal 2 is configured to be driven by the automatic traction device 3 when the automatic traction device 3 is powered on to open the vent 6, and when the automatic traction device 3 is powered off, the seal 2 is reset to block the vent 6. The utility model realizes opening the vent 6 when the power is on and automatically blocks the vent 6 when the power is off through the cooperation of the seal 2 and the automatic traction device 3, thereby preventing gas leakage, improving the stability of the system, and reducing the operating energy consumption of the system and improving the energy utilization efficiency.

[0040] Specifically, the air film structure automatic sealing system further includes a base 4 and an air film body 5 disposed on the base 4, the base 4 and the air film body 5 together constitute a pressure space 1, and the vent 6 is located on the base 4;

[0041] The sealing member 2 comprises a rotating cover plate 21, which is adapted to the vent 6 and is used for rotating the rotating cover plate 21 to the top of the vent 6 to open the vent 6 when the automatic traction device 3 is driven; and for resetting the rotating cover plate 21 to block the vent 6 under the action of gravity when the automatic traction device 3 is powered off.

[0042] Among them, the rotating axis of the rotating cover 21 is located above the vent 6. In a natural state, the rotating cover 21 hangs down under the action of its own weight and blocks the vent 6; when the automatic traction device 3 is powered on, the automatic traction device 3 drives and applies a pulling force to the rotating cover 21, so that the rotating cover 21 rotates upward to open the vent 6, and at this time, gas or materials can enter and exit the pressure space 1; when the automatic traction device 3 is powered off, the automatic traction device 3 cancels the pulling force applied to the rotating cover 21, and the rotating cover 21 rotates downward under the action of its own weight and hangs down to block the vent 6. At this time, gas or materials cannot enter and exit the pressure space 1, so that the air film structure has a strong airtightness, thereby preventing gas leakage in the pressure space 1 and improving the stability of the system. At the same time, it can also reduce the operating energy consumption of the system and improve energy utilization efficiency.

[0043] In the present application, the vent 6 may be an exhaust port 61 or a material delivery channel 72 for materials to enter and exit. Specifically:

The conveying channel 72 connects the pressure space 1 with the outside, and a rotating cover plate 21 and an automatic traction device 3 are arranged at the connection between the conveying channel 72 and the pressure space 1; wherein, the conveying channel 72 constitutes a vent 6.
