[0002] The inspection of the power transmission line is to frequently grasp the operation condition of the line, timely find the equipment defects and the situation along the line, and provide data for the line maintenance. With the development of science and technology, manual climbing for line inspection is no longer needed, and the inspection is performed by remote control of unmanned equipment such as unmanned aerial vehicles and unmanned vehicles.
[0003] The application number 202323004403.7 is a power transmission line inspection device, which comprises an unmanned aerial vehicle, a camera assembly, a suspension cutting assembly and a cleaning assembly. The camera assembly is installed on the top and bottom of the unmanned aerial vehicle. The suspension cutting assembly is installed on the top of the unmanned aerial vehicle. The suspension cutting assembly has a suspension cavity for the entry and exit of the power transmission line. The suspension cavity is provided with a cutting wheel for cutting the surface winding of the power transmission line. The cleaning assembly is installed on the bottom of the unmanned aerial vehicle. The cleaning assembly is used to hook off the winding. The power transmission line inspection device provided by the utility model solves the problem of low efficiency of manual inspection and inconvenience of manual cleaning caused by the fact that the current power transmission line inspection mainly relies on manual work.
[0004] The technical scheme cuts the winding on the line by the cutting wheel, but the distance between the cutting wheel and the unmanned aerial vehicle is small, which causes the unmanned aerial vehicle to need to approach the line during the hooking work. The unmanned aerial vehicle is easily mounted on the line due to the influence of external forces such as resistance, external wind force during the hooking of the winding or improper operation of the staff, which causes damage to the unmanned aerial vehicle and the line. If the distance between the cutting wheel and the unmanned aerial vehicle is extended: 1. If it is extended downward, it cannot exceed the height of the supporting foot, otherwise the cutting wheel is easy to collide with the ground during the landing of the unmanned aerial vehicle, causing damage. 2. If it is extended to the periphery, the center of gravity of the unmanned aerial vehicle will shift to the direction of the cutting wheel, causing the unmanned aerial vehicle to tilt, and the unmanned aerial vehicle needs to output more power during flight to ensure balance.

The embodiment described below through the reference drawings is exemplary, and is only used for explaining the utility model, and can not be understood as the limitation of the utility model.
[0033] The embodiments of this utility model will be described below based on its overall structure.
[0034] Example 1:
[0035] A line inspection and testing device, such as Figures 1-4 As shown, the device includes a drone body 1. A first bracket 5 and a second bracket 6 are fixed to the bottom center of the drone body 1. A swing frame 7 is connected inside the first bracket 5. A first motor 8 is installed at the bottom of the swing frame 7, and a gear 9 is connected to the output end of the first motor 8. An insulating rod 11 penetrates the outer surface of the swing frame 7. The insulating rod 11 is hollow inside, and a rack 10 is fixed to one side of the insulating rod 11. The gear 9 meshes with the rack 10. The insulating rod 11 is slidably connected to the swing frame 7. A limit rod 12 is fixed to the bottom of the insulating rod 11, and the limit rod 12 abuts against the swing frame 7. If the length of the insulating rod 11 is too long, causing the center of gravity of the drone body 1 to shift during flight, the first motor 8 drives the gear 9 to rotate. After rotating, the gear 9 meshes with the rack 10 to drive the cutter. 16 is displaced towards the main body 1 of the drone, causing the insulating rod 11 to partially move to the rear of the drone until the drone's center of gravity is restored to balance; a cutter 16 is connected to the outer surface of the insulating rod 11, and a blade 17 is provided at the bottom of the cutter 16. When the operator operates the main body 1 of the drone to fly, the cutter 16 is moved so that the blade 17 can hook off the entangled material; a worm gear 15 is connected to one side of the swing frame 7, and a second motor 13 is installed at the bottom of the second bracket 6. The output end of the second motor 13 is connected to a worm 14. The swing frame 7 is rotatably connected to the first bracket 5, and the worm gear 15 meshes with the worm 14. The output end of the second motor 13 drives the worm 14 to rotate, and through the worm 14 and the worm gear 15, the swing frame 7 is driven to rotate downward, thereby moving the cutter 16 to below the main body 1 of the drone.
[0036] See Figure 1 In the above embodiment, four fan blades 2 are installed on the top two sides of the drone body 1, and the four fan blades 2 are mirror-distributed. Four support feet 3 are connected to the bottom two sides of the drone body 1, and the four support feet 3 are distributed in a rectangular array. Two cameras 4 are installed on the bottom of the drone body 1, and the two cameras 4 are symmetrically distributed. When the staff places the drone body 1 on the ground, the support feet 3 are in contact with the ground to support the drone body 1, so as to avoid the first motor 8, the second motor 13 and other structures from colliding with the ground and causing damage during subsequent landing. Then, the drone body 1 takes off by rotating the four fan blades 2 at high speed. At this time, the staff can check the surrounding conditions of the drone through the cameras 4, and facilitate the inspection of the line.

[0039] Reference Figures 1-4 In the above embodiment, the cross section of the cutter 16 and the blade 17 are both "C" shaped, and the length of the blade 17 is less than that of the cutter 16. Since the cutter 16 and the blade 17 are both C-shaped, the blade 17 is inward, thereby avoiding the phenomenon of cutting injury caused by the collision between the blade 17 and the personnel or objects during flight and landing, and improving safety.
[0040] The implementation principle of the utility model is as follows: firstly, the specific length of the insulating rod 11 can be selected by oneself, when needing to be inspected, the staff places the unmanned aerial vehicle body 1 on the ground, supports the unmanned aerial vehicle body 1 through the support feet 3 in contact with the ground, avoids the damage caused by the collision between the structures such as the first motor 8 and the second motor 13 and the ground during subsequent landing, then makes the unmanned aerial vehicle body 1 take off through the high-speed rotation of the four fan blades 2, at this time, the staff can check the surrounding conditions of the unmanned aerial vehicle through the camera 4, and it is convenient to inspect the line;
[0041] If the length of the insulating rod 11 is too long to cause the center of gravity of the unmanned aerial vehicle body 1 to deviate during flight, the gear 9 is driven to rotate through the first motor 8, the gear 9 is meshed with the rack 10 after rotating to drive the cutter 16 to displace to the direction of the unmanned aerial vehicle body 1, so that the insulating rod 11 is partially moved to the rear of the unmanned aerial vehicle, until the center of gravity of the unmanned aerial vehicle is restored to balance;
[0042] When needing to hook off the winding object on the line, the gear 9 is driven to reverse through the output end of the first motor 8, so that the rack 10 drives the insulating rod 11 to reversely displace, so that the cutter 16 is away from the unmanned aerial vehicle body 1, finally, the limiting rod 12 abuts against the back of the swing frame 7, avoiding the phenomenon of the insulating rod 11 continuing to displace to cause the insulating rod 11 to fall off from the swing frame 7, the worm 14 is driven to rotate through the output end of the second motor 13, the swing frame 7 is driven to rotate downward through the worm 14 and the worm wheel 15, so that the cutter 16 is moved to the lower side of the unmanned aerial vehicle body 1, at this time, the staff operates the unmanned aerial vehicle body 1 to fly to drive the cutter 16 to displace, so that the blade 17 hooks off the winding object; and since the cutter 16 and the blade 17 are both C-shaped, the blade 17 is inward, thereby avoiding the phenomenon of cutting injury caused by the collision between the blade 17 and the personnel or objects during flight and landing, and improving safety.
