Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a fire-fighting unmanned aerial vehicle with a deflector. Background Art

[0002] Unmanned aerial vehicle, abbreviated as "UAV" in English, is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device, or operated completely or intermittently autonomously by an on-board computer.

[0003] At present, ladder fire trucks are mostly used to solve high-rise fire fighting problems. The effective operating height of ordinary ladder fire trucks is 30-50m, and the higher ones can reach 60-70m. When encountering high-rise fire fighting operations that exceed the effective operating height of ladder fire trucks, they are powerless. At this time, fire-fighting drones will be used to observe the high-rise fire situation. However, the design of the existing fire-fighting drone shroud is unreasonable, and if the shroud is damaged, it is not convenient to replace it later.

[0004] Therefore, a fire-fighting drone with a deflector is needed to improve the above problems. Utility Model Content

[0008] As a preferred solution of the utility model, the connection mode between the plug board and the slot is a sliding plug-in connection.

[0009] As a preferred solution of the utility model, the insertion rod passes through the through hole, and the connection between the insertion rod and the through hole is a sliding connection.

[0010] As a preferred solution of the utility model, the two ends of the spring are fixedly connected to the machine body and the outer pull pad respectively.

[0011] As a preferred solution of the utility model, the inner diameter of the spring is larger than the outer diameter of the insertion rod.

[0012] As a preferred solution of the utility model, the guide head and the guide cover body are designed as an integrally formed structure, and the outer shape structure of the guide cover body is designed as an arc structure.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the utility model, the provided air guide cover body and air guide head can play the role of guiding air and reducing wind resistance when the UAV rises and moves forward and backward. The provided plug plates, slots, through holes, plug rods, springs, external pull pads, pull rings, and limit holes can facilitate the installation and disassembly of the air guide cover body, the air guide head and the body, thereby facilitating the replacement of the air guide cover body and the air guide head.

[0026] A fire-fighting drone with a deflector comprises a body 1, a frame 2 is evenly arranged on the outer wall of the body 1, a propeller 3 is installed on the upper side of the frame 2, a deflector body 4 is installed on the top of the body 1, and plug boards 5 are symmetrically arranged on the bottom of the deflector body 4, slots 6 are opened on the top of the body 1 and corresponding to the plug boards 5, through holes 7 are opened on the left and right sides of the body 1, and plug rods 8 are arranged inside the through holes 7. The outer wall of the plug rod 8 is sleeved with a spring 9, an outer end of the plug rod 8 is provided with an outer pull pad 10, and a pull ring 11 is provided on the outer side of the outer pull pad 10. A limiting hole 12 is opened in the middle of the plug board 5, a deflector head 13 is arranged on the front and rear sides of the deflector body 4, and a support leg 14 is arranged at the bottom of the frame 2.

[0027] In this embodiment, the connection between the plug plate 5 and the slot 6 is a sliding plug-in connection, the plug rod 8 passes through the through hole 7, and the connection between the plug rod 8 and the through hole 7 is a sliding connection. The two ends of the spring 9 are fixedly connected to the body 1 and the outer pull pad 10 respectively. The inner diameter of the spring 9 is larger than the outer diameter of the plug rod 8. The guide head 13 and the guide cover body 4 are an integrally formed structure, and the outer shape structure of the guide cover body 4 is an arc-shaped structure. The set guide cover body 4 and guide head 13 can play a role in guiding and reducing wind resistance when the drone rises and moves back and forth. The set plug plate 5, slot 6, through hole 7, plug rod 8, spring 9, outer pull pad 10, pull ring 11, and limit hole 12 can facilitate the installation and disassembly of the guide cover body 4, the guide head 13 and the body 1, thereby facilitating the replacement of the guide cover body 4 and the guide head 13.

[0028] The working process of the utility model is as follows: first, insert the plug plate 5 into the slot 6. At the same time, the plug rod 8 is pulled outward by the pull ring 11 and the outer pull pad 10. After the plug plate 5 is fully inserted into the slot 6, the pull ring 11 and the outer pull pad 10 are released. At this time, the spring 9 will rebound and drive the plug rod 8 to be inserted into the limiting hole 12. At this time, the installation of the air guide cover 4 and the air guide head 13 is completed. Finally, the unmanned flight is started. At this time, the air guide cover 4 and the air guide head 13 will play a role in reducing wind resistance during the flight of the drone. The set air guide cover 4 and the air guide head 13 can play a role in guiding and reducing wind resistance when the drone rises and moves back and forth. The set plug plate 5, slot 6, through hole 7, plug rod 8, spring 9, outer pull pad 10, pull ring 11, and limiting hole 12 can facilitate the installation and disassembly of the air guide cover 4, the air guide head 13 and the body 1, thereby facilitating the replacement of the air guide cover 4 and the air guide head 13.
