Description

Technical Field

[0001] This utility model relates to the field of drone protection technology, specifically to a collision protection structure for an inspection drone. Background Technology

[0002] With the rapid development of drone technology, inspection drones have been widely used in various fields such as power line inspection, security monitoring, environmental monitoring, and forestry surveys. Their advantages, including flexibility, high efficiency, and the elimination of the need for on-site personnel, effectively reduce the intensity of manual labor and operational risks. However, inspection scenarios are often complex and varied. During low-altitude flight, drones are prone to collisions with obstacles such as tree branches, building corners, and the auxiliary structures of power poles. Such collisions can not only cause deformation of the drone's wings and damage to its fuselage, but in severe cases, can also cause the drone to lose control and crash, resulting in equipment damage and interruption of the inspection mission. They may even cause secondary injuries to personnel or facilities on the ground.

[0003] Existing drone protection structures use flexible covers, which have a certain buffering capacity, but the installation and fixing methods are complicated, cannot be adapted to drone wings of different sizes, and the protection range is difficult to adjust flexibly according to the inspection environment, resulting in poor versatility. Furthermore, some cover structures have large gaps, which cannot block relatively small branches. Utility Model Content

[0004] The technical problem this invention aims to solve is that while existing flexible dome covers for drones have a certain buffering capacity, they are complex to install, not compatible with wings of different sizes, have difficulty in flexibly adjusting the protection range, have poor versatility, and have large gaps that cannot block small branches.

[0005] To solve the above problems, the technical solution adopted by this utility model is a collision protection structure for an inspection drone, including a cover structure, the cover structure including a connecting component, an upper cover plate and a lower cover plate respectively provided above and below the connecting component, and an arc-shaped soft cover plate provided between the upper cover plate and the lower cover plate to facilitate shape adjustment.

[0006] The connecting assembly includes a connecting hoop, the two ends of which are fastened together by screws and nuts to be fixed to the outside of the connecting rod of the wing. The lower side of the connecting hoop is fixed to the lower cover plate by a long rod one, and the upper side of the connecting hoop is provided with an adjustment assembly, which is fixed to the upper cover plate by a long rod two.

[0007] Several connecting rods are evenly fixed on the side of the arc-shaped soft cover. The outer sides of both ends of the connecting rods are provided with threaded grooves. The two ends of the connecting rods pass through the upper cover and the lower cover respectively, and are fixed in position by nuts cooperating with the threaded grooves, so as to form an integral protective structure.

[0008] As a further embodiment of this utility model: the diameter of the holes on the sides of the upper cover plate and the lower cover plate is larger than the diameter of the connecting rod, which facilitates the insertion of the connecting rod and enables the arc-shaped soft cover plate to be installed in multiple positions, and its installation position can be flexibly adjusted.

[0009] As a further embodiment of this utility model: the cover structure is provided with a drone wing structure, which can provide independent protection for a single wing.

[0010] As a further embodiment of this invention, the diameters of the upper and lower cover plates are larger than the rotation diameter of the UAV wing, which allows for sufficient space for the installation of the curved soft cover plate to accommodate wings of different diameters.

[0011] As a further embodiment of this utility model, the connecting hoop is provided on the outside of the fixing rod of the drone wing.

[0012] As a further embodiment of this utility model: the adjustment assembly includes a connecting frame fixed on the upper side of the connecting hoop, a limiting square groove is opened on the inner side of the connecting frame, an adjustment rod is slidably arranged in the limiting square groove, the top end of the adjustment rod is fixed to one end of the second long rod, a threaded hole is opened in the middle of the adjustment rod, and an adjustment screw that cooperates with the threaded hole is rotatably arranged in the square groove. By rotating the adjustment screw, the adjustment rod can be driven to move up and down, thereby driving the upper cover plate to move up and down through the second long rod to adapt to different wings.

[0013] Compared with the prior art, the advantages of this utility model are as follows: 1. The connecting component of this application adopts a connecting hoop design, which can be fastened to the outside of the drone wing fixing rod by screws and nuts, without the need for complicated tools or professional operation. The arc-shaped soft cover plate is quickly fixed to the upper and lower cover plates by the connecting rod with threaded grooves. The disassembly and assembly process is simple, solving the problem of complicated installation of existing protective structures and facilitating later maintenance and component replacement; 2. An adjustment component is added. By adjusting the screw and the threaded engagement of the adjusting rod, the upper cover plate can be driven to slide up and down, flexibly adjusting the distance between the upper and lower cover plates. This design can adapt to drone wings of different sizes; 3. The diameter of the holes in the upper and lower cover plates is larger than the diameter of the connecting rod. By adjusting the fixed position of the connecting rod, the tension and coverage of the arc-shaped soft cover plate can be changed. In addition, the diameter of the holes in the upper and lower cover plates and the side of the arc-shaped soft cover plate is small, which can prevent small branches from penetrating the wing.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0029] Combined with appendix Figure 1-3First, install the connecting component 2. Attach the connecting hoop 21 to the outside of the fixing rod of the UAV wing 5. Tighten both ends of the connecting hoop 21 with screws and nuts to ensure that the connecting hoop 21 is firmly bound to the fixing rod. Then, connect one end of the long rod 22 to the lower side of the connecting hoop 21 by welding or bolting. Fix the other end of the long rod 22 to the corresponding position of the lower cover plate 12. Fix the other end of the long rod 23 to the upper cover plate 11. This completes the initial assembly of the connecting component 2 with the upper and lower cover plates.

[0030] Combined with appendix Figure 2 , 5 Next, install the arc-shaped soft cover plate 3. Align the two ends of several connecting rods 31 that are evenly fixed on the side of the arc-shaped soft cover plate 3 with the holes on the side of the upper cover plate 11 and the lower cover plate 12 respectively and pass them through. Since the diameter of the holes on the side of the upper cover plate 11 and the lower cover plate 12 is larger than the diameter of the connecting rods 31, the front, back, left and right positions of the connecting rods 31 in the holes can be adjusted according to the protection requirements of the actual inspection environment and the size of the UAV wing 5. After the position is determined, screw the nuts into the threaded grooves on the outer side of the two ends of the connecting rods 31 and tighten them so that the arc-shaped soft cover plate 3, the upper cover plate 11, and the lower cover plate 12 form a closed overall protective structure.

[0031] Combined with appendix Figure 4 , 6 If it is necessary to adapt to drone wings 5 ​​of different sizes, the adjusting screw 45 can be rotated. The screw 45 and the adjusting rod 43 are connected by a thread, which drives the adjusting rod 43 to slide up and down in the limiting square groove 42. This, in turn, drives the upper cover plate 11 to move up and down synchronously through the long rod 23, so as to accurately adjust the distance between the upper cover plate 11 and the lower cover plate 12. At the same time, the nuts at both ends of the connecting rod 31 can be loosened again to adjust the installation position of the connecting rod 31, change the tension and coverage of the arc-shaped soft cover plate 3, so that the protective structure can be fully adapted to the current wing size and inspection environment. The entire installation process does not require professional tools or complicated operations. It is easy to disassemble and assemble, and can provide independent protection for a single drone wing 5. If maintenance or replacement of parts is required in the future, it can be disassembled simply by loosening the corresponding nuts. The operation is simple and efficient.

[0032] The working principle of this application is as follows: The anti-collision protection structure of the inspection drone of this utility model is firmly bound to the fixing rod of the drone wing 5 through the connecting clamp 21 of the connecting component 2, realizing a reliable connection between the protective structure and the drone. The adjusting component 4 drives the adjusting rod 43 to slide up and down in the limiting square groove 42 by rotating the adjusting screw 45 and utilizing the threaded engagement between the adjusting screw 45 and the adjusting rod 43. In turn, the upper cover plate 11 is moved up and down through the long rod 23, flexibly adjusting the distance between the upper cover plate 11 and the lower cover plate 12 to adapt to drone wings 5 ​​of different sizes. The diameter of the holes on the sides of the upper cover plate 11 and the lower cover plate 12 is larger than the diameter of the connecting rod 31, so that the connecting rod 31 can be adjusted and installed in multiple positions within the holes. By adjusting the fixed position of the connecting rod 31, the tension of the arc-shaped soft cover plate 3 can be changed. The coverage area meets the protection needs of different inspection environments. In the overall protective structure formed by the upper cover plate 11, the lower cover plate 12 and the arc-shaped soft cover plate 3, the diameter of the upper cover plate 11 and the lower cover plate 12 is larger than the rotation diameter of the UAV wing 5. The arc-shaped soft cover plate 3 is fixed by evenly distributed connecting rods 31, which greatly reduces the gap of the cover. It can effectively block obstacles such as small branches and building corners from reaching into the UAV wing 5, avoiding scratches or jamming of the wing. At the same time, the arc-shaped soft cover plate 3 has flexible buffering performance, which can absorb the impact force when it collides, and prevent the impact force from being rigidly transmitted to the fuselage and wing, achieving a combination of rigid and flexible protection effect. Moreover, the structure can independently protect a single UAV wing 5, ensuring the safe operation of the UAV wing 5 during the inspection process and improving the flight safety and operational stability of the UAV.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
