Technical Field
[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a four-axis unmanned aerial vehicle for special fire-spraying operation on power lines. Background Art
[0002] With the development of unmanned aerial vehicle technology, people's vision is not only limited to the ground. Unmanned aerial vehicles can fly in the sky. They can carry high-definition camera equipment for recording and bring it back to the ground. People can watch images through the video. The development and application of unmanned aerial vehicles are also very rapid. Now there are also agricultural unmanned aerial vehicles that can spray pesticides; security unmanned aerial vehicles that can maintain order at the scene; surveying and mapping unmanned aerial vehicles that can survey and map the local ground; and fire-spraying unmanned aerial vehicles that can spray flames to remove the garbage wrapped around high-voltage lines.
[0003] At the same time, in order to deal with some entanglements on power lines (such as hanging plastic bags, kites, etc.), fire-spraying unmanned aerial vehicles with special operation requirements are designed. Such fire-spraying unmanned aerial vehicles will not cause damage to the lines while spraying fire to eliminate entanglements.
[0004] Further research finds that the fire-spraying device at the bottom of the fire-spraying unmanned aerial vehicle needs regular maintenance. However, the disassembly and installation of the existing fire-spraying devices are relatively difficult. The complex disassembly and installation processes will prolong the equipment preparation time and affect the overall operation efficiency. For scenarios that require frequent replacement of the fire-spraying device or rapid deployment, the difficulty of disassembly and installation will limit the application range of the fire-spraying unmanned aerial vehicle. Moreover, the support frame at the bottom of the fire-spraying unmanned aerial vehicle cannot adjust the opening angle, and the unmanned aerial vehicle will be greatly restricted during operation and cannot flexibly respond to various complex environments and task requirements. Summary of the Utility Model
[0005] To solve the above technical problems, the utility model provides a four-axis unmanned aerial vehicle for special fire-spraying operation on power lines, which solves the problems that the fire-spraying device at the bottom of the current fire-spraying unmanned aerial vehicle needs regular maintenance, but the disassembly and installation of the existing fire-spraying devices are relatively difficult. The complex disassembly and installation processes will prolong the equipment preparation time and affect the overall operation efficiency. For scenarios that require frequent replacement of the fire-spraying device or rapid deployment, the difficulty of disassembly and installation will limit the application range of the fire-spraying unmanned aerial vehicle. Moreover, the support frame at the bottom of the fire-spraying unmanned aerial vehicle cannot adjust the opening angle, and the unmanned aerial vehicle will be greatly restricted during operation and cannot flexibly respond to various complex environments and task requirements.
[0006] To achieve the above purposes, the technical solution adopted by the utility model is as follows:
[0007] A four-axis drone for special fire-spraying operation on power lines, including a drone body. On both the left and right sides of the bottom surface of the drone body, fixed blocks are fixedly connected. Between the two fixed blocks, two hanging rods are fixedly connected. On the surfaces of the two hanging rods, two hooks are respectively clamped. At the bottom of each of the four hooks, a fixing plate is fixedly connected. An installation groove is opened on the bottom surface of the fixing plate. On both the left and right side walls inside the installation groove, locking grooves are opened. At the bottom surface of the fixing plate, an installation frame is provided. At the front end inside the installation frame, a bidirectional lead screw is rotatably connected;
[0008] At the rear side inside the installation frame, a guiding rod is fixedly connected. At the bottom surface of the installation frame, a fire-spraying device is fixedly connected; On the outer surfaces of the left and right ends of the bidirectional lead screw, locking plates are respectively threadedly connected. The rear ends of the locking plates are respectively slidably connected to the guiding rod. The two locking plates are respectively clamped inside the two locking grooves. At the bottom surface of the installation frame, a fire-spraying device is fixedly connected. Below the drone body, a fixed support is provided.
[0009] Preferably, one end of the bidirectional lead screw penetrates through the side of the installation frame and is fixedly connected with a knob outside the installation frame.
[0010] Preferably, at the top of the drone body, a base is fixedly connected. Inside the base, connecting rods are respectively rotatably connected at the front and rear sides. At the bottom of the two connecting rods, a camera is rotatably connected.
[0011] Preferably, on the outer surfaces of the left and right ends of the two hanging rods, compression springs are sleeved. One end of the compression spring close to the hook is fixedly connected with a pressing plate. The pressing plate is slidably connected to the hanging rod, and the pressing plate abuts against the hook.
[0012] Preferably, the fixed support includes an installation plate. The installation plate is fixedly connected to the middle position of the bottom surface of the drone body. At the front and rear sides of the bottom surface of the installation plate, supports are fixedly connected.
[0013] Preferably, at the lower ends of the two supports, support legs are rotatably connected. At the bottom of the two support legs, cross bars arranged horizontally are fixedly connected. At the left and right ends of the two cross bars, foot pads are sleeved.
[0014] Preferably, at the left and right ends inside the two cross bars, threaded sleeves are provided.

[0016] Compared with the prior art, the advantages of the present utility model are as follows:
[0017] 1. The utility model drives the bidirectional lead screw to rotate by turning the knob. Due to the screw-thread engagement relationship, the two locking plates move towards each other, so that the upper ends of the locking plates are clamped into the locking grooves. This design can achieve locking and unlocking by simply rotating a single knob, greatly simplifying the operation process and improving work efficiency. For operators, this intuitive and easy-to-operate design enhances the user experience, reduces the operation difficulty and complexity, enabling non-professionals to easily get started. Moreover, the locking plates are firmly clamped in the locking grooves, ensuring the stability and safety of the flame spraying device during use and reducing the accidental risks caused by loosening or falling off.
[0018] 2. By manually rotating the threaded sleeve in the utility model, under the screw-thread engagement relationship, the extension rods on both sides will extend out of or retract into the threaded sleeve. When the extension rods extend, the opening angle of the fixed bracket increases, and when the extension rods retract, the opening angle decreases. There is no need to replace the entire fixing device or perform complex adjustments. Simply rotating the threaded sleeve can quickly adjust the opening angle of the fixed bracket, which can significantly improve work efficiency. By changing the opening angle of the fixed bracket, it can adapt to different working environments, improving the versatility and adaptability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.
[0029] Embodiment 1
[0030] As Figure 1-7 shown, the embodiment of the present utility model provides a four-axis drone for special flame spraying operation on power lines, including a drone body 1. On the left and right sides of the bottom surface of the drone body 1, fixed blocks 2 are fixedly connected. Between the two fixed blocks 2, two hanging rods 3 are fixedly connected. On the surfaces of the two hanging rods 3, two hooks 4 are respectively clamped; at the bottom of the four hooks 4, fixed plates 5 are fixedly connected. On the bottom surface of the fixed plate 5, an installation groove 6 is opened. On the left and right side walls inside the installation groove 6, locking grooves 7 are opened; on the bottom surface of the fixed plate 5, an installation frame 9 is provided. At the front end inside the installation frame 9, a bidirectional lead screw 10 is rotatably connected. At the rear side inside the installation frame 9, a guide rod 11 is fixedly connected. At the bottom surface of the installation frame 9, a flame spraying device 8 is fixedly connected; on the outer surfaces of the left and right ends of the bidirectional lead screw 10, locking plates 13 are respectively threadedly connected. The rear ends of the locking plates 13 are respectively slidably connected to the guide rod 11;
[0031] The two locking plates 13 are respectively clamped inside the two locking grooves 7. A flame spraying device 8 is fixedly connected to the bottom surface of the installation frame 9. A fixed bracket 14 is provided below the drone body 1.
[0032] In the specific use process, when the flame spraying device 8 is installed, first, the locking plate 13 is inserted into the installation groove 6 and the top surface of the locking plate 13 is made to contact the top surface of the installation groove 6. Then, the knob 12 is rotated to drive the bidirectional lead screw 10 to rotate. Through the thread matching relationship, the two locking plates 13 move towards each other, so that the upper ends of the locking plates 13 are clamped into the locking grooves 7, and the installation of the flame spraying device 8 is completed. When it is necessary to adjust the opening angle of the fixed bracket 14, manually rotate the threaded sleeve 1406. Under the thread matching relationship, the extension rods 1407 on both sides will extend out of or retract into the threaded sleeve 1406. When the extension rod 1407 extends, the opening angle of the fixed bracket 14 increases. When the extension rod 1407 retracts, the opening angle decreases.
[0033] Specifically, one end of the bidirectional lead screw 10 penetrates through the side of the mounting frame 9 and is fixedly connected to a knob 12 outside the mounting frame 9. By rotating the knob 12 to drive the bidirectional lead screw 10, the locking plate 13 can be quickly snapped into the locking groove 7, realizing the quick installation and disassembly of the flame spraying device 8 and improving the operation efficiency.
[0034] Preferably, a base 15 is fixedly connected to the top of the UAV body 1. Connecting rods 16 are rotatably connected to the front and rear sides inside the base 15. The bottom of the two connecting rods 16 is rotatably connected to a camera 17. By connecting the camera 17 through the connecting rods 16, its angle can be flexibly adjusted, providing an all-round view below the UAV for the operator and enhancing the safety and accuracy of the operation.
[0035] Specifically, it should be noted that compression springs 18 are sleeved on the outer surfaces of the left and right ends of the two hanging rods 3. One end of the compression spring 18 close to the hook 4 is fixedly connected to a pressing plate 19. The pressing plate 19 is slidably connected to the hanging rod 3 and abuts against the hook 4. The compression spring 18 provides a continuous inward pressure for the hook 4. Through the pressing plate 19, the tight connection between the hook 4 and the hanging rod 3 is ensured. Without an additional locking device, when the UAV is flying or operating, the compression spring 18 can absorb part of the vibration and impact, protecting the flame spraying device 8 from damage.
[0036] Specifically, the fixed support 14 includes a mounting plate 1401 which is fixedly connected to the middle position of the bottom surface of the UAV body 1. Supports 1402 are fixedly connected to the front and rear sides of the bottom surface of the mounting plate 1401. When operating on uneven or complex terrains, by increasing the opening angle of the fixed support 14, the support area is increased, improving the stability and safety of the UAV.
[0037] Specifically, support legs 1403 are rotatably connected to the lower ends of the two supports 1402. Cross bars 1404 arranged horizontally are fixedly connected to the bottoms of the two support legs 1403. Foot pads 1405 are sleeved on the left and right ends of the two cross bars 1404.
[0038] Specifically, the surfaces of the propellers and the support legs of the UAV body are coated with a high-temperature resistant coating.
[0039] Specifically, threaded sleeves 1406 are arranged at the left and right ends inside the two cross bars 1404. Extension rods 1407 are threadedly connected to the front and rear sides inside the two threaded sleeves 1406. One ends of the four extension rods 1407 away from the threaded sleeves 1406 are respectively fixedly connected to the two cross bars 1404. When long-distance transportation or storage is required, the extension rods 1407 can be retracted into the threaded sleeves 1406, reducing the volume of the fixed support 14 and facilitating carrying and storage.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present utility model.
