Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of airport guarantee, and particularly relates to a movable and foldable deflector, which is especially suitable for airflow deflection protection of airplane test run, maintenance and temporary takeoff point, and can realize agile deployment, convenient transportation and efficient deflection, and meet the needs of flexible test run, emergency guarantee and rapid construction of temporary takeoff facilities of the airport. BACKGROUND

[0002] The deflector device is a key equipment for guaranteeing the safety of airplane takeoff, and is used for bearing airplane thrust and efficient deflection. The land airport usually sets up the anti-blow deflector in the parking apron, maintenance apron and other areas where the airplane frequently test runs and starts, deflects the engine jet airflow when the airplane test runs, and prevents the noise, wake, flying sand generated in the process of airplane takeoff and test run from causing harm to the vehicles and equipment.

[0003] The airport adopts the fixed deflector device, and there are two installation and fixing modes of the deflector used: one is the mode of pouring concrete, which has the defects of long construction period, high cost, generation of a large amount of industrial waste and immobility; and the other is the mode of fixing on the ground by using anchor bolts, multiple anchor bolts bear the shear force and overturning moment generated from the airplane tail jet thrust, the fixed mode does not affect the secondary migration of the deflector screen, and is beneficial to reducing the use cost, but the fixed mode has many bolt fixing points, and it is complex and difficult to adjust and position, correspondingly, the strength requirement of the installation ground concrete is higher, and the strength requirement of the structure support of the deflector itself is higher. The airplane with the fixed deflector can only test run at the designated positions such as the test run apron and the maintenance hangar of the airport, and the simple test run of the airplane parts after maintenance also needs to enter the maintenance hangar, which greatly reduces the test run and maintenance efficiency. The fixed deflector device cannot meet the needs of flexible test run and maintenance guarantee of the airport.

[0004] In addition, the fixed deflector cannot provide the guarantee capacity when the airplane performs the task or makes an emergency landing. The temporary takeoff facility needs to be rapidly constructed at the temporary takeoff point of the airport, and only needs simple tools and manpower to complete the assembly and deployment in a short time when used, and is placed at a suitable position; and after use, it can be rapidly removed to improve the response efficiency.

[0005] The existing assembly type deflector screen technology has improved in the aspect of "detachability", but still has not broken through the core limitation of "immobility and no folding function", and the specific problems are as follows: 1. Patent CN216861849U (Prefabricated assembly type airport guide screen): Although it realizes assembly type installation through "bottom plate + longitudinal support rod + inclined support rod", it needs to fix the bottom plate on the ground through expansion bolts, and the essence is still a fixed structure; there is no folding design, and it needs to be disassembled into bottom plate, support rod, guide panel and other independent parts during transportation, occupying a large space (single group transportation volume exceeds 5 cubic meters), and relying on the metal cage filled with concrete to improve stability, poor adaptability to temporary site geological conditions, unable to meet the emergency deployment requirements.

[0006] 2. Patent CN220595204U (Assembly type steel structure guide screen): three-dimensional corrugated steel plate and bolt connection are adopted to realize repeated use, but still need to be fixed through anchor bolts and concrete pavement or base, and cannot be moved flexibly; without folding function, the support rod, cross rod, corrugated steel plate and other parts need to be disassembled before transportation, and 3-5 people need to cooperate for 4-6 hours for on-site assembly, which is low in deployment efficiency; and it is not adapted to general containers, and needs special vehicles for cross-airport transportation, which is high in cost and slow in response.

[0007] In summary, the existing technology generally has the problems of immobility, low deployment efficiency, inconvenience of transportation, high requirement for ground anchoring, and inability to meet temporary support requirements, which has been difficult to adapt to the needs of modern airport flexible test, emergency landing and temporary landing point rapid construction. The movable and foldable guide plate has the ability of agile deployment and convenient transportation on the basis of ensuring full-force deflection protection capacity. It is adapted to general containers, modular design, and can complete deployment in a very short time. It has no special requirement (anchoring) ability for the site, has anti-skid, shock absorption and anti-overturning ability, and has maintenance-free and low-maintenance ability. SUMMARY

The panel is corrugated, comprising an upper corrugated panel 4 and a lower corrugated panel 5. The support structure comprises a front support frame 6, an upper support frame 7, a lower support rod 8, a locking rod 9, a connecting rod, and a rear cross support. Figure 2 Figure 3

[0027] The upper corrugated panel 4 is installed above three upper support frames 7, the upper support frames 7 are triangular, and rotating hole one 11-1 and rotating hole two 11-2 are arranged on both sides of the short straight angle side of the upper support frames 7, and the rear cross support one 12-1 is located between the two upper support frames 7 and connected with the long straight angle side of the upper support frames 7. The connecting rod one 10-1 and the connecting rod two 10-2 are located between the two upper support frames 7 and connected with the short straight angle side of the upper support frames 7.

The connecting rod six 10-6 has a spiral anchoring hole one 15-1 in the middle, which is used for connecting with the spiral anchoring structure 3 and fixing the deflector.

[0029] The lower corrugated panel 5 is installed above three front support frames 6, the front support frames 6 are triangular, and the three front support frames 6 are connected through the connecting rod three 10-3, the connecting rod four 10-4 and the connecting rod five 10-5, the connecting rod three 10-3 and the connecting rod five 10-5 are provided with the spiral anchoring hole two 15-2 and the spiral anchoring hole three 15-3, and the spiral anchoring structure 3 is connected with the ground. One end of the hypotenuse of the front support frame 6 is provided with a rotating hole three 11-3 with the same size as the rotating hole two 11-2 of the upper support frame. The rotating hole two 11-2 of the upper support frame is connected with the rotating hole three 11-3 of the front support frame through the locking pin two 13-2 of the locking rod 9.
