[0037] Example

[0038] This embodiment provides a retractable air-supported membrane passage door, see reference. Figure 1 As shown, the structure includes a first door 1, a second door 2, a telescopic frame 3, a flexible material 4, and a track 5. The first door 1 and the second door 2 are both openable door structures, specifically roller shutters or other types of door structures. The telescopic frame 3 is connected to the first door 1 on one side and to the second door 2 on the other side. The telescopic frame 3 moves either the first door 1 or the second door 2, switching the air-supported membrane channel door to an open or closed state. The flexible material 4 is fitted onto the telescopic frame 3, thereby forming a relatively sealed channel around the flexible material 4, the first door 1, and the second door 2. In this embodiment, the flexible material 4 can be a membrane material or other materials.

[0039] The track 5 is located below the telescopic frame 3. In this embodiment, the track is installed on or below the ground, and the end of the telescopic frame 3 is movably installed on the track 5 along the length of the track 5.

[0040] When a vehicle needs to enter the air-supported membrane structure, the telescopic frame 3 extends the air-supported membrane passage door, opening the second door 2 while keeping the first door 1 closed, allowing the vehicle to enter the passage. Then, the second door 2 is closed and the first door 1 is opened, allowing the vehicle to enter the air-supported membrane structure. When the vehicle needs to exit the air-supported membrane structure, the process is reversed. When the vehicle does not need to enter or exit the air-supported membrane structure, the air-supported membrane passage door is in an idle state. The telescopic frame 3 is retracted, reducing the volume of the air-supported membrane passage door and thus minimizing space occupation.

[0041] The retractable air-supported membrane passage door provided in this embodiment unfolds the telescopic frame 3 to form a passage for the vehicle to enter during the vehicle entry process, and keeps the telescopic frame 3 closed when the vehicle is not entering or exiting, thereby reducing the space occupied.

[0042] Specifically, it also includes an edge sealing compensation component 6. The edge sealing compensation component 6 is installed at the end of the track 5 and is used to contact the bottom of the first door 1 or the second door 2 in the unfolded state. The edge sealing compensation component 6 seals the first door 1 or the second door 2 in the unfolded state, ensuring the airtightness of the passage inside and out, thereby ensuring the airtightness of the air film.

[0043] By having the edge sealing compensation piece 6 contact the bottom of the first door 1 or the second door 2 in the unfolded state, the telescopic frame 3 maintains the airtightness of the air film channel when it is in the unfolded state, further ensuring the airtightness of the air film inside and outside during vehicle entry.

[0044] Specifically, the configuration of the first door 1 and the second door 2 can be divided into outward opening, inward opening, and double opening.

[0045] Internally open structure reference Figure 2 As shown, the first door 1 is installed on the air-supported membrane, and the second door 2 is located outside the air-supported membrane. The telescopic frame 3 drives the second door 2 to move outside the air-supported membrane. Since the first door 1 is installed on the air-supported membrane, its bottom can directly touch the ground after it is closed, maintaining a seal. However, the second door 2 is movable, so there is a certain gap between the bottom of the second door 2 and the ground. By setting an edge sealing compensation piece 6 to contact the bottom of the second door 2 in the unfolded state, the air-supported membrane can be kept sealed inside and outside when the first door 1 is open and the second door 2 is closed.

[0046] External opening structure reference Figure 3As shown, the first door 1 is located inside the air-supported membrane, and the second door 2 is installed on the air-supported membrane. The telescopic frame 3 drives the first door 1 to move within the air-supported membrane. Correspondingly, since the second door 2 is installed on the air-supported membrane, it directly touches the ground and maintains a seal. The first door 1 is movable, therefore there is a certain gap between the bottom of the first door 1 and the ground. By setting an edge sealing compensation piece 6 to contact the bottom of the first door 1 in the unfolded state, the first door 1 can be closed, and the second door 2 can maintain a seal between the inside and outside of the air-supported membrane when it is open.

[0047] Double-opening structural reference Figure 4 As shown, the first door 1 is located inside the air-supported membrane, and the second door 2 is located outside the air-supported membrane. The telescopic frame 3 includes an inner telescopic frame 35 and an outer telescopic frame 36. The inner telescopic frame 35 is connected to the first door 1, driving the first door 1 to move inside the air-supported membrane; the outer telescopic frame 36 is connected to the second door 2, driving the second door 2 to move outside the air-supported membrane. Since the first door 1 and the second door 2 are movable, edge sealing compensation parts 6 need to be set separately to ensure the seal inside and outside the air-supported membrane. Furthermore, since the first door 1 and the second door 2 both move to the middle position of the air-supported membrane channel door in the retracted state, there are gaps between the first door 1, the second door 2 and the ground. In order to ensure the seal inside and outside the air-supported membrane in the retracted state, an intermediate sealing compensation part 7 is provided in the middle of the track 5. The intermediate sealing compensation part 7 is used to contact the bottom of the first door 1 or the second door 2 in the retracted state.

[0048] Specifically, the telescopic frame 3 includes a scissor-type telescopic frame 32 and multiple portal support frames 31; the multiple portal support frames 31 are arranged along the length of the track 5, and the scissor-type telescopic frame 32 is connected to each portal support frame 31 in sequence; the bottom of each portal support frame 31 is connected to a rolling wheel 33, and the rolling wheel 33 abuts against the top surface of the track 5. It also includes a drive device 34, which is connected to at least one rolling wheel 33. The drive device 34 drives the rolling wheel 33 to rotate, thereby moving the telescopic frame 3 to realize the folding and unfolding of the air-supported membrane channel door.

[0049] Specifically, refer to Figure 5 As shown, the track 5 includes a top plate 51 and a vertical plate 52. The top plate 51 and the vertical plate 52 are connected to form a T-shape; the bottom of the portal support frame 31 is also connected to a ground roller 37, which extends below the top plate 51. The ground roller 37 is used for limiting the movement of the roller 33 and guiding its movement, thus preventing the air-supported tunnel door from shifting to the side or tipping over.

[0050] Specifically, the top of the top plate 51 is arc-shaped, and the rolling wheel 33 is in contact with the top of the top plate 51.

[0051] Specifically, the edge sealing compensation member 6 is provided with guide slopes 61 on both sides. The guide slopes 61 facilitate the entry and exit of vehicles, avoid excessive damage to the edge sealing compensation member 6, and ensure sealing performance. Correspondingly, the intermediate sealing compensation member 7 is also provided with guide slopes 61 on both sides.

[0052] In this embodiment, the sealing compensation component can be made of a material with a certain degree of resilience and wear resistance, such as plastic or rubber.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
