Description

Technical Field

[0001] This utility model relates to the field of airport flow guidance screen technology, and in particular to a modular and detachable flow guidance screen. Background Technology

[0002] Airport jet deflectors are important safety protection facilities for large aircraft test runs. They can deflect the aircraft's exhaust jets at a certain angle, effectively ensuring the safety of personnel and surrounding objects in the airport. They also have the characteristics of noise reduction and increasing the jet deflection effect during aircraft test runs.

[0003] Currently, domestic wind deflectors are mainly fixed concrete wind deflectors and fixed steel structure wind deflectors, which have the following shortcomings:

[0004] (1) The concrete anti-blowing deflector screen has a small main body size and a small number of configurations, and its height and length cannot meet the requirements of modern new aircraft.

[0005] (2) Fixed steel plate type flow guide screens have a safety hazard of being blown over and collapsing because their own weight and wind resistance load are all concentrated in the reinforced concrete support.

[0006] (3) Fixed flow guide screens cannot meet the requirements for flexible mobile assembly and use in multiple scenarios.

[0007] Therefore, it is necessary to provide a new modular and detachable flow guide screen to solve the above-mentioned technical problems. Utility Model Content

[0030] This invention proposes a modular and detachable flow guide screen, aiming to solve the problems of low structural stability and inability to adapt to various operational needs of existing flow guide screens.

[0031] like Figure 1 As shown, the modular detachable airflow deflector in this embodiment includes a support module 1, a panel module 2, and an end compensation module 3. One or more support modules 1 are assembled to form a triangular support body, which has an installation ramp. The shape of the panel module 2 matches the shape of the installation ramp, and the panel module 2 is detachably mounted on the installation ramp. The end compensation module 3 is detachably mounted on the top of the support module 1. Depending on the actual operational requirements for different heights and lengths, one or more support modules 1 can be assembled to form a triangular support body with an installation ramp. The panel module 2 is mounted on the installation ramp to facilitate the airflow being directed out at a certain angle. The triangular support body effectively improves the stability of the overall structure. Furthermore, the modular design not only enables component integration, reducing the number of complex parts, but also allows for the rapid disassembly and installation of the airflow deflector.

[0032] In this embodiment, when test-flying a small aircraft, multiple support modules 1 arranged in one or a single layer can be used to support a 3m high panel module 2, and an end compensation module 3 can be installed on top of the support module 1 to meet the airflow requirements when test-flying a small aircraft; when test-flying a large aircraft, each support module 1 can be spliced ​​in two or more layers to obtain a panel module 2 that can support a height of 5m.

[0033] The support module 1 includes connecting components and triangular frames 1.1. There are two or more triangular frames 1.1, spaced apart along the same straight line. Adjacent triangular frames 1.1 are detachably connected via the connecting components. The panel module 2 is detachably connected to the triangular frames 1.1. The number of triangular frames 1.1 and the spacing between adjacent triangular frames 1.1 are determined according to the actual dimensional requirements of the operation. Connecting them via the connecting components ensures the connection strength between the triangular frames 1.1 while allowing for flexible adjustment according to actual needs.

[0034] Specifically, the connecting assembly includes a rear support 1.2, a reinforcing rod 1.3, and a connecting rod 1.4; see also [reference needed]. Figure 2 The triangular frame 1.1 includes a first support section 1.1.1, a second support section 1.1.2, and an inclined section 1.1.3 connected end-to-end. The first support sections 1.1.1 of two adjacent triangular frames 1.1 are connected by a rear support member 1.2 or a reinforcing rod 1.3. The second support section 1.1.2 is horizontally positioned, and the second support sections 1.1.2 and inclined sections 1.1.3 of two adjacent triangular frames 1.1 are connected by a connecting rod 1.4. The panel module 2 is detachably connected to the inclined section 1.1.3. The first support section 1.1.1 and the second support section 1.1.2 are vertically positioned, or symmetrically positioned about the vertical direction. The rear support rod 1.2.1, the reinforcing rod 1.3, and the connecting rod 1.4 effectively enhance the overall structural strength. The vertical positioning of the first support section 1.1.1 and the second support section 1.1.2 ensures the stability of the panel module 2 while reducing the floor space required. In another example of this embodiment, the first support segment 1.1.1 and the second support segment 1.1.2 are symmetrically arranged to cooperate with the inclined segment 1.1.3 to form an isosceles triangle structure, which further enhances the stability of the support for the panel module 2 and effectively reduces the risk of being blown over and collapsing.

[0035] Furthermore, the rear support member 1.2 includes two cross-arranged support rods 1.2.1, with both ends of the support rods 1.2.1 connected to two adjacent triangular frames 1.1 respectively; the rear support member 1.2 and the reinforcing rod 1.3 are alternately arranged.

[0036] Furthermore, a Z-shaped reinforcement is provided between the first support section 1.1.1 and the inclined section 1.1.3. The Z-shaped reinforcement can effectively enhance the structural strength of the triangular frame 1.1.

[0037] The inclined section 1.1.3 and the mounting slope have the same inclination angle, and the angle between the inclined section 1.1.3 and the horizontal plane is 45° to 75°. Each support module 1 is spliced ​​to form a mounting slope with the same inclination angle as the inclined section 1.1.3. The splicing method is simple, which helps improve assembly efficiency and ensures that airflow can be discharged along the specified angle. In this embodiment, the angle between the inclined section 1.1.3 and the horizontal plane is preferably 60°.

[0038] In this embodiment, the end compensation module 3 includes an end compensation rod 3.1 and an end panel 3.2. Each first support segment 1.1.1 in each of the uppermost support modules 1 is provided with an end compensation rod 3.1, and the end panel 3.2 is vertically disposed on each end compensation rod 3.1. The end panel 3.2 is vertically disposed on the top of the triangular support body through each end compensation rod 3.1 to guide the airflow upward.

[0039] Specifically, the first support section 1.1.1 has a vertically oriented mounting hole at its end furthest from the second support section 1.1.2; the end compensating rod 3.1 includes a connecting section and a mounting section connected together. The connecting section is detachably installed in the mounting hole using fasteners, and the mounting section is connected to the end panel 3.2. The connecting section of the end compensating rod 3.1 is inserted into the corresponding mounting hole and fixed with fasteners. The assembly structure is simple, the operation is convenient, and it helps to improve the efficiency of assembly and disassembly.

[0040] In addition, see also Figure 3 The panel module 2 includes one or more folding units 2.1. Each folding unit 2.1 comprises two hinged folding panels 2.1.1, which are detachably mounted on the mounting slope via pins. Each folding unit 2.1 cooperates to cover the mounting slope. The folding unit 2.1, composed of two hinged folding panels 2.1.1, facilitates transportation, reduces installation steps, and allows for adjustment of the number of folding units 2.1 according to actual operational needs, offering high flexibility. In this embodiment, one side of the folding panel 2.1.1 is a smooth guide surface, while the other side has a mesh-like reinforcing structure.

[0041] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
