[0030] Example

[0031] See Figure 1 This embodiment provides a foldable airport flow guidance screen, including a main panel assembly 1, a secondary panel assembly 2, and a support frame assembly 3;

[0032] The main panel assembly 1 and the secondary panel assembly 2 are hinged together by a pin. The secondary panel assembly 2 can rotate and fold around the hinge point to adjust the height of the flow guide screen and meet the flow guide requirements of different models.

[0033] The support frame assembly 3 includes at least one set of detachably connected support frame one 3.1, adjusting rod group 3.2, and support frame two 3.3. The support frame one 3.1 is detachably connected to the main panel assembly 1 by bolts. The support frame one 3.1 has a modular design and is used to support the main panel assembly 1. The support frame two 3.3 is bolted to the support frame one 3.1. The support frame two 3.3 has a modular design and is used to provide support for the adjusting rod group 3.2, while also strengthening the support of the flow guide screen. The adjusting rod group 3.2 has an adjustable length and is detachably connected between the support frame two 3.3 and the secondary panel assembly 2. The adjusting rod group 3.2 is used to support the secondary panel assembly 2. Its detachable connection with the secondary panel assembly 2 facilitates the rotation and folding of the secondary panel assembly 2. The adjustable length of the adjusting rod group 3.2 allows for the adjustment of the tilt angle of the secondary panel assembly 2, enabling the setting of flow guide screens at different angles to meet the actual needs of multiple working conditions.

[0034] In this embodiment, preferably, the support frame 3.1 is a right-angled triangular frame, and the main panel assembly 1 is detachably connected to the inclined surface of the right-angled triangular frame; in this embodiment, the right-angled triangular frame is welded from channel steel and has a modular design.

[0035] The right-angled triangular frame includes two sets of right-angled triangular supports 3.1.1 arranged opposite each other along the width direction of the main panel assembly 1. The two sets of right-angled triangular supports 3.1.1 are detachably connected by a connecting rod 3.1.2. The two sets of right-angled triangular supports 3.1.1 and the connecting rod 3.1.2 work together to achieve stable support for the main panel assembly 1.

[0036] The second support frame 3.3 is a rectangular frame, and the vertical surfaces of the rectangular frame and the right-angled triangular frame are connected by bolts. Preferably, the width of the rectangular frame is the same as the width of the right-angled triangular frame, and the height of the rectangular frame is the same as the height of the right-angled triangular frame. In this embodiment, the second support frame 3.3 is welded from channel steel and has a modular design.

[0037] In this embodiment, the adjusting rod group 3.2 is provided in two sets. The first ends of the two adjusting rod groups 3.2 are respectively hinged to the two endpoints of the upper end of the rectangular frame that are away from the right-angled triangular frame. The second ends of the two adjusting rod groups 3.2 are respectively detachably connected to the secondary panel assembly 2 through pins.

[0038] The adjusting rod assembly 3.2 includes adjusting rod one 3.2.1 and adjusting rod two 3.2.2 arranged at an angle. The angle between adjusting rod one 3.2.1 and adjusting rod two 3.2.2 increases with the increase of the length of the secondary panel assembly 2 to meet the support strength of the secondary panel assembly 2.

[0039] Specifically, the first end of the adjusting rod 3.2.1 is hinged to the upper end of the rectangular frame away from the right-angled triangle frame, and the second end of the adjusting rod 3.2.1 is hinged to the upper end of the secondary panel assembly 2; the first end of the adjusting rod 3.2.2 is hinged to the upper end of the rectangular frame away from the right-angled triangle frame, and the second end of the adjusting rod 3.2.2 is hinged to the middle of the secondary panel assembly 2.

[0040] When the height of the flow guide screen needs to be adjusted, the second end of the adjusting rod assembly 3.2 can be disassembled. Adjusting rod 3.2.1 can be rotated counterclockwise to overlap the vertical surface of the support frame 3.3, and adjusting rod 3.2.2 can be rotated clockwise to overlap the horizontal surface of the support frame 3.3. The secondary panel assembly 2 can be rotated forward and folded to fit against the main panel assembly 1. See [reference needed]. Figure 2 The secondary panel assembly 2 can also be rotated backward and folded flat onto the horizontal plane of the support frame 3.3, see [reference]. Figure 3 .

[0041] In this embodiment, preferably, both the first adjusting rod 3.2.1 and the second adjusting rod 3.2.2 are telescopic rods. The telescopic rods extend and retract to adjust their length, thereby adjusting the tilt angle of the secondary panel assembly 2 and setting up flow guide screens at different angles. Alternatively, by replacing the first adjusting rod 3.2.1 and the second adjusting rod 3.2.2 with different lengths, the tilt angle of the secondary panel assembly 2 can be adjusted, thereby setting up flow guide screens at different angles.

[0042] In this embodiment, both the main panel assembly 1 and the secondary panel assembly 2 include a guide frame and a guide panel, with the guide panel mounted on the windward side of the guide frame. A reinforcing plate is provided within the guide frame along its width, supporting the guide panel and reducing deflection and stress. Both the main panel assembly 1 and the secondary panel assembly 2 are modularly designed and directly connected via hinge pins during assembly.

[0043] For specific installation instructions, please refer to the following steps:

[0044] 1) Connect the main panel assembly 1 and the secondary panel assembly 2 with a pin. The secondary panel assembly 2 can rotate forward or backward around the pin.

[0045] 2) Connect the inclined surface of the support frame 3.1 to the main panel assembly 1 with bolts;

[0046] 3) Connect support frame 2 (3.3) and support frame 1 (3.1) with bolts;

[0047] 4) Connect the adjusting rod assembly 3.2 between the support frame 2 3.3 and the secondary panel assembly 2 to support the secondary panel assembly 2.

[0048] The 5m air deflector can be installed using the above installation method, which can meet the test conditions of most large aircraft.

[0049] When the actual operating conditions of the airport do not require a 5m airflow barrier, see [reference needed]. Figure 2 and Figure 3 One end of the adjusting rod assembly 3.2 can be removed and rotated and folded. The secondary panel assembly 2 rotates around the hinge point and is attached to the support frame 2 3.3 or the main panel assembly 1, thereby enabling the switching from a 5m flow guide screen to a 3m flow guide screen to meet the operating conditions of different models.

[0050] When the angle of the flow guide screen needs to be adjusted under actual working conditions, the tilt angle of the secondary panel assembly 2 can be adjusted by changing the length of the adjustment rod group 3.2.

[0051] The flow guide screen provided by this utility model adopts a modular design for its main panel assembly 1, secondary panel assembly 2, and support frame 1 3.1 and support frame 2 3.3, which can realize quick assembly and disassembly, improve work efficiency, and reduce installation and disassembly costs. The main panel assembly 1 and secondary panel assembly 2 are hinged, which can realize the switching of the flow guide screen height to meet the flow guide requirements of different models. The height of the adjusting rod group 3.2 is adjustable, which can realize the adjustment of the tilt angle of the secondary panel assembly 2, thereby realizing the setting of flow guide screens at different angles to meet the needs of different working conditions.

[0052] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
