Description

Technical Field

[0001] The invention relates to the technical field of aviation aircraft, and in particular to a UAV layout and installation structure with a fire extinguishing bomb and an optoelectronic pod, and the UAV. Background Art

[0002] With the development of technology and the need to build a national emergency rescue system, aviation forces have begun to invest heavily in emergency rescue. At present, aviation forces are mainly used in air patrol monitoring, reconnaissance command and personnel transportation in fire rescue. Although some aircraft also participate in aerial hanging water spraying and spreading fire extinguishing agents, the fire extinguishing efficiency is not high. Precision-guided fire-extinguishing bombs have emerged. By dropping guided fire-extinguishing bombs from aircraft, it is possible to "fight early, fight small, and fight well" on the initial fire, and put out the fire in its infancy.

[0003] Since fire-fighting bombs are generally in the 100-200kg range, the commonly used fire-fighting helicopters are limited by their own structure and other conditions, and the number of bombs they can carry is limited to a certain extent. In recent years, the rapid development of large fixed-wing UAVs has injected fresh vitality into various fields. Large fixed-wing UAVs can carry heavier and more fire-fighting bombs when used in the fire-fighting field due to their high load-bearing capacity, thus achieving better targeted fire-fighting effects. Large fixed-wing UAVs can make full use of the space on the wings to carry fire-fighting bombs.

[0004] The loading of heavy external objects is generally not considered in the structural design of general fixed-wing UAVs. The wings of large fixed-wing UAVs are characterized by many dense ribs and a fabric-covered structure that only maintains the shape but does not bear the force. This makes it difficult for the wings of large fixed-wing UAVs to directly bear the weight of fire-extinguishing bombs. This problem needs to be solved. In the prior art, Chinese patent publication No. CN117163288A discloses a Y5 / Y5B series aircraft fire-fighting platform, including two front supports, two rear supports, a front corner box and a rear corner box; the front corner box is arranged opposite to the rear corner box; the front corner box and the rear corner box are fixedly connected by a base for leveling. The two bases are symmetrical about the symmetry axis of the aircraft fuselage; two fire extinguishing bombs are arranged at the lower part of the belly, and the other two fire extinguishing bombs are arranged at the lower part of the left and right wings respectively; the fuselage belly reinforcement structure is arranged on the pylon, and the fuselage belly reinforcement structure includes longitudinal reinforcement structures respectively arranged on the front beam and the rear beam, transverse reinforcement structures arranged between the longitudinal reinforcement structures, and end transverse reinforcement parts respectively arranged between the two ends of the longitudinal reinforcement structure; it is used to balance the lateral bending moment generated by the fire extinguishing bomb mounted on the belly due to its own gravity, the inertia moment along the heading during flight, and the turning during normal flight of the aircraft;

[0005] The solution of the above-mentioned public technology is to mount the fire extinguishing bomb on the belly of the aircraft through a reinforced structure, which cannot solve the problem of mounting the fire extinguishing bomb on the wing to increase the bomb capacity, especially for large fixed-wing UAVs that have been put into use. Therefore, it is necessary to optimize and improve the layout and installation structure of the UAV with fire extinguishing bombs and optoelectronic pods. Summary of the invention

The outer wall of the circumference of the mounting seat 7 is provided with a groove that matches the positioning boss 16. The mounting seat 7 is positioned with the positioning ring 6 through the groove and the positioning boss 16. The belly bottom plate 5 is fixedly connected to the lower wall of the fuselage 1 by screws. The inner wall of the belly bottom plate 5 and the lower wall of the fuselage 1 are provided with a wire hole for the power plug to pass through, so as to facilitate the power connection operation. The mounting seat 7 can be positioned and installed relatively quickly through the positioning ring 6. The positioning boss 16 can prevent the mounting seat 7 from rotating after being installed in the positioning ring 6, thereby improving the installation efficiency.

[0039] In order to smoothly mount the fire extinguishing bomb assembly 9, multiple groups of fire extinguishing bomb assemblies 9 are respectively arranged on the lower walls of the two groups of wing bottom plates 8 through the bomb hanging structure. The two groups of wing bottom plates 8 are respectively arranged on the left and right sides of the belly bottom plate 5, and the wing bottom plates 8 and the belly bottom plate 5 are connected by an adjustable connecting rod structure. The adjustable connecting rod structure includes a first rotating seat 10, a second rotating seat 11, a connecting rod 14 and a connecting sleeve 15. The first rotating seat 10 is fixedly connected to the lower wall of the belly bottom plate 5 and is located on the side close to the wing bottom plate 8. The second rotating seat 11 is fixedly connected to the wing bottom plate 8 is located at the lower wall and is located on the side close to the abdomen bottom plate 5, the second rotating seat 11 and the first rotating seat 10 are aligned in the front-to-back direction when viewed from above, the inner wall of the first rotating seat 10 is rotatably connected to the first rotating sleeve 12 through a rotating pin, the inner wall of the second rotating seat 11 is rotatably connected to the second rotating sleeve 13 through a rotating pin, the connecting rod 14 is fixedly connected to the outer circumferential wall of the first rotating sleeve 12, the connecting sleeve 15 is slidably connected to the end of the connecting rod 14 away from the first rotating sleeve 12, the end of the connecting sleeve 15 away from the connecting rod 14 is fixedly connected to the outer circumferential wall of the second rotating sleeve 13, and the first rotating sleeve 12 and the first rotating seat 10, the second rotating sleeve 13 and the second rotating seat 11, and the connecting rod 14 and the connecting sleeve 15 are all locked by screws. The belly of the fuselage 1 and the lower wall of the wing 2 are usually not in the same plane, and the height difference between the belly of the fuselage 1 and the lower wall of the wing 2 in different types of large fixed-wing UAVs is different. In order to share part of the weight of the wing bottom plate 8 when the fire extinguishing bomb assembly 9 is mounted on the belly bottom plate 5 and the belly of the fuselage 1 reinforced by the prior art, a connecting rod 14 and a connecting sleeve 15 are arranged between the wing bottom plate 8 and the belly bottom plate 5. After the first rotating sleeve 12 and the first rotating seat 10, the second rotating sleeve 13 and the second rotating seat 11, and the connecting rod 14 and the connecting sleeve 15 are tightened by screws, the wing bottom plate 8 and the belly bottom plate 5 are fixed together, so that the belly bottom plate 5 forms a supporting effect on the wing bottom plate 8. In order to adapt to the height difference between the lower wall of the wing 2 and the belly of the fuselage 1 of different models, the connecting rod 14 and the connecting sleeve 15 can be slidably connected after the screws are loosened, and the total length after the connection can be adjusted, thereby adapting to the height difference between the lower wall of the wing 2 and the belly of the fuselage 1 of different models;

[0040] In order to fix the wing bottom plate 8 to the wing 2, two groups of first jackets 18 are slidably connected to the front side of the wing bottom plate 8, and the two groups of first jackets 18 are distributed left and right. Two groups of second jackets 20 are slidably connected to the end of the wing bottom plate 8 away from the first jacket 18, and the two groups of second jackets 20 are distributed left and right. The side view cross-section of the first jacket 18 and the second jacket 20 is a V-shaped shape with opposite mouths. One end of the V-shaped second jacket 20 is connected to the wing bottom plate 8, and two groups of first sliding grooves that penetrate the front end of the wing bottom plate 8 are arranged inside the wing bottom plate 8. A group of first sliding strips 17 are slidably connected to the inner side walls of the two groups of first sliding grooves, respectively. The two groups of first jackets 18 are respectively rotatably connected to the ends of the two groups of first sliding strips 17 away from the wing bottom plate 8, and the first jackets 18 are rotatably connected to the first sliding strips 17 through rivets. Two groups of second slide grooves are arranged inside the bottom plate 8 and are connected to the rear end of the wing bottom plate 8. The inner side walls of the two groups of second slide grooves are respectively slidably connected with a group of second slide bars 19. The two groups of second jackets 20 are respectively rotatably connected to the ends of the two groups of second slide bars 19 away from the wing bottom plate 8. The second jackets 20 and the second slide bars 19 are rotatably connected by rivets. After the wing bottom plate 8 is attached to the lower wall of the wing 2, the first jacket 18 and the second jacket 20 can be used to respectively cover the front edge and the rear edge of the wing 2. After the first jacket 18 and the second jacket 20 clamp the wing 2, the first slide bar 17 and the second slide bar 19 can be locked with the wing bottom plate 8 by screws. The sliding connection between the first slide bar 17 and the second slide bar 19 and the wing bottom plate 8 can facilitate the action of clamping or loosening the wing 2, and can also be suitable for wings 2 of different widths.

[0041] In order to improve the connection strength between the wing bottom plate 8 and the wing 2, a steel wire rope 21 is fixedly connected to the other end of the V-shaped second jacket 20, and a buckle 25 is provided on the V-shaped outer wall of the first jacket 18. The buckle 25 consists of a fixing frame and a buckling handle assembly rotatably connected to the inner wall of the fixing frame. A clamping structure is provided between the buckle 25 and the end of the steel wire rope 21 away from the second jacket 20. The clamping structure includes a hook 26 and a connecting frame 27. The hook 26 is rotatably connected to the end of the buckle 25 facing the second jacket 20, and the connecting frame 27 is fixedly connected to the end of the steel wire rope 21 away from the second jacket 20. The connecting frame 27 is projected from above. The lower part is a rectangular frame, and the inner side wall of the connecting frame 27 is fixedly connected with multiple groups of transverse ribs 31 in sequence from front to back. After the first jacket 18 and the second jacket 20 clamp the wing 2, the connecting frame 27 at one end of the steel wire rope 21 is pulled to the vicinity of the buckle 25, and the buckling handle assembly of the buckle 25 is opened to move the hook 26 toward the second jacket 20, and the transverse rib 31 on the connecting frame 27 that can match the hook 26 is hung in the hook 26, and then the buckling handle assembly is buckled, and the hook 26 is pulled back by the buckling handle assembly to tighten the steel wire rope 21, so that the wing bottom plate 8 is fixed to the wing 2 from above the wing 2 through the steel wire rope 21;

[0042] In order to prevent the buckle 25 from accidentally disengaging during use, a limiting structure for maintaining the buckle 25 in a fastened state is provided on the outer wall of the first jacket 18 and on one side of the buckle 25. The limiting structure includes a limiting seat 22, a limiting pin 24, a third slide bar 28 and a spring 29. The limiting seat 22 is fixedly connected to the outer wall of one side of the two V-shaped sides of the first jacket 18 that is not connected to the wing bottom plate 8 and is located on one side of the buckle 25. The third slide bar 28 is slidably connected to the inner right wall of the limiting seat 22 in a penetrating manner. The end of the third slide bar 28 extending to the right side of the limiting seat 22 is fixedly connected to the handle 23. The limiting pin 24 is fixedly connected to the end of the third slide bar 28 extending into the interior of the limiting seat 22. A limiting groove 30 is provided at the end of the limiting pin 24 away from the third slide bar 28. The limiting groove 30 is connected to the end of the limiting pin 24 away from the third slide bar 28 and the front and rear side walls of the limiting pin 24. 29 is sleeved on the outer wall of the third slide bar 28 and is located between the limit pin 24 and the right inner wall of the limit seat 22. The handle thickness of the buckling handle assembly is less than the height of the limit slot 30 in the up and down directions. Before buckling the buckling handle assembly, the limit pin 24 is first pulled by the handle 23 so that the limit pin 24 squeezes the spring 29 and retracts into the limit seat 22. When the buckling handle assembly is buckled, the handle 23 is released, and the limit pin 24 is popped out from the limit seat 22 by the elasticity of the spring 29. During the popping-out process, the limit slot 30 on the limit pin 24 is inserted into the outside of the handle of the buckling handle assembly. The elastic force of the spring 29 prevents the limit pin 24 from automatically retreating, thereby preventing the buckling handle assembly from being disengaged through the limit slot 30 on the limit pin 24, avoiding accidental disengagement during use, and improving the safety of use. The cross-section of the third slide bar 28 is a rectangular structure, which can prevent the limit pin 24 from axial rotation.

[0043] This embodiment also provides a UAV, including a fuselage 1, wings 2, tail wings 3, propellers 4 and the above-mentioned UAV layout and installation structure with fire extinguishing bombs and optoelectronic pods, the belly bottom plate 5 is fixedly connected to the lower wall of the fuselage 1 by four sets of screws, and the wing bottom plate 8 is connected to the lower wall of the wing 2.

[0044] Working principle: The mounting seat 7 can be positioned and installed relatively quickly. The positioning boss 16 can prevent the mounting seat 7 from rotating after being installed inside the positioning ring 6, thereby improving the installation efficiency. The belly of the fuselage 1 and the lower wall of the wing 2 are usually not in the same plane, and the height difference between the belly of the fuselage 1 and the lower wall of the wing 2 in different types of large fixed-wing drones is different. In order to share part of the weight of the wing bottom plate 8 when the fire extinguishing bomb assembly 9 is mounted on the belly bottom plate 5 and the belly of the fuselage 1 reinforced by the prior art, a connecting rod 14 and a connecting sleeve 15 are arranged between the wing bottom plate 8 and the belly bottom plate 5, and between the first rotating sleeve 12 and the first rotating seat 10, and between the second rotating sleeve 13 and the second rotating seat 11 After the connecting rod 14 and the connecting sleeve 15 are tightened by screws, the wing bottom plate 8 and the belly bottom plate 5 are fixed together, thereby forming a supporting effect of the belly bottom plate 5 on the wing bottom plate 8. In order to adapt to the height difference between the lower wall of the wing 2 and the belly of the fuselage 1 of different models, the connecting rod 14 and the connecting sleeve 15 can be slidably connected after the screws are loosened, and the total length after the connection can be adjusted to adapt to the height difference between the lower wall of the wing 2 and the belly of the fuselage 1 of different models. After the wing bottom plate 8 is attached to the lower wall of the wing 2, the first jacket 18 and the second jacket 20 can be used to respectively cover the front edge and the rear edge of the wing 2. After the first jacket 18 and the second jacket 20 clamp the wing 2, the first jacket 18 and the second jacket 20 can be screwed together. The slide bar 17 and the second slide bar 19 are locked with the wing bottom plate 8. The sliding connection between the first slide bar 17 and the second slide bar 19 and the wing bottom plate 8 can facilitate the clamping or loosening of the wing 2, and can also be applied to wings 2 of different widths. After the first jacket 18 and the second jacket 20 clamp the wing 2, the connecting frame 27 at one end of the wire rope 21 is pulled to the vicinity of the buckle 25, the buckling handle assembly of the buckle 25 is opened, so that the hook 26 moves toward the second jacket 20, and the transverse rib 31 on the connecting frame 27 that can match the hook 26 is hung in the hook 26, and then the buckling handle assembly is buckled, and the hook 26 is pulled back by the buckling handle assembly to tighten the wire rope 21, so that the wire rope 21 can be tightened by the wire rope. 21 fixes the wing bottom plate 8 to the wing 2 from above the wing 2. Before buckling the buckling handle assembly, first pull the limit pin 24 through the handle 23, so that the limit pin 24 squeezes the spring 29 and retracts into the limit seat 22. When the buckling handle assembly is buckled, release the handle 23, and the limit pin 24 is ejected from the limit seat 22 by the elasticity of the spring 29. During the ejection process, the limit groove 30 on the limit pin 24 is inserted into the outside of the handle of the buckling handle assembly. The elastic force of the spring 29 prevents the limit pin 24 from automatically retreating, thereby preventing the buckling handle assembly from being disengaged through the limit groove 30 on the limit pin 24, avoiding accidental disengagement during use, and improving the safety of use.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
