AI Technical Summary
When existing power line inspection drones take off and land in complex terrains such as mountains and jungles, the fixed length of the support frame makes it difficult to adapt to uneven ground, causing the drones to easily tip over or tilt, increasing the risk of equipment damage, and also resulting in poor flexibility.
It adopts a rotor and support structure design, including a connecting seat, a moving frame, a rotating seat, and a telescopic component. The rotor is driven to rotate by a motor, and the support structure can flexibly adjust its height to adapt to terrain undulations. The telescopic component also buffers the landing impact. At the same time, a heat dissipation structure is adopted, which uses a heat spreader and heat-conducting copper pipes to transfer heat to the heat dissipation fins for efficient heat dissipation.
It improves the stability and safety of drones during takeoff and landing in complex terrain, reduces the risk of tipping over, and protects internal equipment through non-porous heat dissipation, maintaining stable flight of the drone and equipment safety.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a power line inspection UAV. Background Technology
[0002] Traditional manual inspections of cable facilities are inefficient, pose high safety risks, and are limited by terrain. Therefore, the development of power inspection drones has been adopted. With the advantages of high-altitude flight and the ability to carry multiple sensors, drones can perform all-weather, all-time inspections, improve inspection efficiency and safety, reduce manpower input, quickly detect equipment defects, and prevent accidents.
[0003] Chinese patent CN213936416U discloses a power line inspection drone, including a body. Symmetrical support rods are fixedly connected to the bottom of the body, and a base rod is fixedly connected to the bottom of each support rod. A battery box is fixedly connected to the bottom of the body. A sealed door is hinged to the front of the battery box. A battery frame is placed on the inner bottom wall of the battery box. Threaded holes are provided on both sides of the battery box, and a fixing bolt is threaded into the inner wall of each threaded hole. A sliding block is fixedly connected to the side of two fixing bolts that are close to each other. A support plate is fixedly connected to the inner wall of the battery box. This power line inspection drone enhances the stability of the battery after installation and achieves rapid heat dissipation, avoiding the problem of battery overheating and damage due to prolonged operation, thus ensuring the normal operation of the drone.
[0004] The aforementioned patent still has the following shortcomings: it has the defect of poor flexibility. Since the support frame of the existing device is usually an integrated structure design, in complex terrain such as mountains and jungles, the fixed length support frame is difficult to adapt to the uneven ground, which makes the drone prone to tipping or tilting due to unstable support points during take-off and landing, increasing the risk of equipment damage. Utility Model Content
[0005] This utility model provides a power line inspection drone that solves the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
[0007] An embodiment of this utility model provides a power line inspection drone, including a shell, and further comprising:
[0008] The rotating arms are fixed on both sides of the outer casing, and a motor is installed on one side of the rotating arm, and a rotor is installed at the end of the output shaft of the motor.
[0009] A support structure is provided on both sides of the bottom end of the outer shell. The support structure includes a connecting seat fixed to both sides of the bottom end of the outer shell, a movable frame rotatably connected to both sides of the bottom end of the connecting seat, a rotating seat rotatably connected to the bottom end of the movable frame, and a telescopic component for mounting one side of the movable frame.
[0010] The base plate is fixed to the bottom of the rotating seat;
[0011] The battery is installed at the bottom inside the casing, and a shielding shell is installed at the top of the battery, with electronic components installed inside the shielding shell;
[0012] A heat dissipation structure is located at the top of the shielding shell to achieve non-porous heat dissipation of the shielding shell;
[0013] The camera is mounted at the bottom of the casing.
[0014] The above technical solution uses a motor to drive the rotor to rotate, while the shielding shell protects the electronic components from external electromagnetic interference. The heat dissipation structure dissipates the heat inside the shielding shell, and a camera is used to capture images of the power equipment.
[0015] Furthermore, the telescopic assembly includes a top rod installed on one side of the movable frame, a bottom rod installed at the bottom end of one side of the movable frame, a movable piston rotatably connected to the top end of one set of bottom rods, a compression cylinder rotatably connected to the bottom end of one set of top rods, and a return spring installed between the movable piston and the compression cylinder.
[0016] The above technical solution uses a mobile frame to move the base plate to both sides, and the top rod and bottom rod to move the piston inside the compression cylinder, effectively buffering the landing impact and absorbing vibration energy.
[0017] Furthermore, the movable piston forms a telescopic structure with the compression cylinder via a return spring, and the movable piston and the compression cylinder form a sliding structure.
[0018] Through the above technical solution, the support structure can flexibly buffer and adapt to terrain undulations by extending and sliding between the moving piston and the compression cylinder, thereby improving take-off and landing stability.
[0019] Furthermore, the adjacent sets of the movable frames are arranged in parallel, and the connecting seats are installed on both sides of the bottom end of the outer casing by bolts.
[0020] The above technical solution, which uses bolts to fix the connector, ensures structural stability and facilitates disassembly and maintenance, thereby enhancing the reliability and adaptability of the UAV in complex environments.
[0021] Furthermore, the heat dissipation structure includes heat dissipation holes opened inside both sides of the outer shell, a heat dissipation plate installed on the top of the electronic component, a heat-conducting copper pipe inserted inside the top of the heat dissipation plate, a fixing plate fixed to the top of the shielding shell, and heat dissipation fins fixed to the top of the fixing plate and connected to the heat-conducting copper pipe.
[0022] The above technical solution introduces airflow through heat dissipation holes, allowing the heat spreader to quickly absorb heat from electronic components, and the thermally conductive copper pipes transfer the heat to the heat dissipation fins, achieving efficient heat dissipation.
[0023] Furthermore, several sets of the heat-conducting copper pipes are installed inside the heat spreader, and the several sets of heat-conducting copper pipes are distributed at equal intervals inside the heat spreader.
[0024] The above technical solution can quickly and evenly transfer the heat generated by electronic components to the heat sink fins, avoiding localized overheating.
[0025] The above-described solution of this utility model has at least the following beneficial effects:
[0026] 1. This utility model uses a movable frame to move the base plate to both sides, and causes the top rod and bottom rod to drive the movable piston to slide inside the compression cylinder, effectively buffering the landing impact and absorbing vibration energy. This realizes the telescopic buffering function of the device, ensuring stability when taking off and landing on uneven ground, reducing the risk of rollover, and effectively dispersing the landing impact force to protect the fuselage and internal equipment.
[0027] 2. This utility model introduces airflow through heat dissipation holes, allowing the heat spreader to quickly absorb heat from electronic components. The heat-conducting copper pipes then transfer the heat to the heat dissipation fins, thereby achieving efficient heat dissipation of the device. The heat pipe technology enables hole-free heat conduction, avoiding local overheating. At the same time, the absence of openings maintains the integrity and sealing of the shielding shell, preventing electromagnetic leakage. Attached Figure Description

[0036] like Figures 1 to 5 As shown, an embodiment of this utility model provides a power line inspection drone, including a shell 1, and further comprising:
[0037] The rotating arms 5 are fixed on both sides of the outer shell 1, and a motor 3 is installed on one side of the rotating arm 5, and a rotor 2 is installed at the end of the output shaft of the motor 3.
[0038] Support structure 4 is provided on both sides of the bottom end of the outer shell 1. The support structure 4 includes connecting seats 402 fixed on both sides of the bottom end of the outer shell 1, movable frame 401 rotatably connected to both sides of the bottom end of the connecting seats 402, rotating seat 408 rotatably connected to the bottom end of the movable frame 401, and telescopic component installed on one side of the movable frame 401.
[0039] The base plate 6 is fixed to the bottom end of the rotating seat 408;
[0040] Battery 11 is installed at the bottom inside the outer casing 1, and a shielding shell 9 is installed at the top of battery 11. Electronic components 10 are installed inside the shielding shell 9.
[0041] The heat dissipation structure 7 is located at the top of the shielding shell 9 and is used to achieve non-porous heat dissipation of the shielding shell 9.
[0042] Camera 8 is mounted at the bottom of housing 1.
[0043] In this embodiment of the utility model, the rotor 2 is driven to rotate by the motor 3 to provide lift for the drone. At the same time, the flight attitude of the electronic component 10 is adjusted to ensure flight stability. The shielding shell 9 protects the electronic component 10 from external electromagnetic interference, and the heat dissipation structure 7 dissipates the heat inside the shielding shell 9. The camera 8 is used to capture images of the power equipment to realize the inspection function.
[0044] like Figure 4 As shown, the telescopic assembly includes a top rod 403 installed on one side of the movable frame 401, a bottom rod 407 installed at the bottom end of one side of the movable frame 401, a movable piston 405 rotatably connected to the top of one set of bottom rods 407, a compression cylinder 404 rotatably connected to the bottom end of one set of top rods 403, and a return spring 406 installed between the movable piston 405 and the compression cylinder 404.

The two adjacent sets of movable frames 401 are distributed in parallel, and the connecting seat 402 is installed on both sides of the bottom end of the outer casing 1 by bolts.
[0045] In this embodiment of the utility model, when the base plate 6 contacts the ground, the device moves downward due to inertia, causing the movable frames 401 on the left and right sides to move the base plate 6 to the sides, lowering the center of gravity of the device to prevent it from tipping over. At the same time, the top rod 403 cooperates with the bottom rod 407 to make the movable piston 405 slide in the compression cylinder 404, and the return spring 406 provides elastic support to buffer the impact and pressure, and allows the movable frame 401 and the rotating seat 408 to automatically adjust their height according to the terrain, ensuring that the UAV remains stable when taking off and landing in complex terrain.

Several sets of heat-conducting copper pipes 703 are installed inside the heat dissipation plate 702, and the several sets of heat-conducting copper pipes 703 are distributed at equal intervals inside the heat dissipation plate 702.
[0047] In this embodiment of the utility model, the heat generated by the electronic components 10 inside the shielding shell 9 is absorbed by the heat dissipation plate 702, and then the heat-conducting copper pipe 703 transfers the heat to the heat dissipation fins 704. The heat dissipation fins 704 increase the heat dissipation area and accelerate the heat dissipation to the outside, realizing heat dissipation without holes. The heat dissipation fins 704 are fixed to the top of the shielding shell 9 by the fixing plate 705 to ensure that the heat dissipation structure 7 is stable and reliable. During the flight of the device, the external airflow is introduced into the device through the heat dissipation holes 701 to improve the heat dissipation effect.
[0048] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
