Description
Technical Field
[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle power inspection device. Background Art
[0002] With the development and progress of technology, the power inspection technology has developed rapidly and made great progress. The popularization of intelligent inspection equipment such as unmanned aerial vehicles has brought great convenience to the operation and maintenance personnel of substation, power plant and line equipment when monitoring equipment line faults.
[0003] During the process of cable inspection by unmanned aerial vehicle, the unmanned aerial vehicle flies to inspect the high-voltage overhead power line cables, and the ground personnel remotely control it and process the data such as the images transmitted back by the unmanned aerial vehicle. Since the time for manually processing images to determine whether there are faults in the cables is relatively long, in conventional operations, the unmanned aerial vehicle needs to return along the original route or hover in the air. Both returning along the original route and hovering in the air of the unmanned aerial vehicle will consume a large amount of battery power and reduce the endurance. In order to save power, the staff mostly land the unmanned aerial vehicle vertically on the ground and wait. However, in mountainous areas and dense forests such as Guangxi, the high-voltage cables are erected high in the air, and the mountainous areas and dense forests below the cables seriously affect the landing of the unmanned aerial vehicle and endanger the safety of the unmanned aerial vehicle. During the inspection of long-distance transmission cables, both returning along the original route and hovering in the air of the unmanned aerial vehicle will consume a large amount of battery power and reduce the endurance.
[0004] In the published Chinese patent application, the publication number: CN215753052U, the patent name: A power inspection device based on an unmanned aerial vehicle. Although, by setting a protection component, during the use process, when approaching the wire, all the third motors can be started. After all the third motors are started, they drive all the baffle plates to rotate. When all the baffle plates rotate, they drive all the protection nets to rotate. When the protection net rotates to a position corresponding to the fixed pipe, all the third motors are turned off. At this time, the protection net will protect the fan and prevent the blades of the fan from getting entangled with the wire. However, the protection net increases the wind resistance of the unmanned aerial vehicle and reduces the endurance of the unmanned aerial vehicle. The setting of the protection net cannot prevent the body of the unmanned aerial vehicle from colliding with the cable. At the same time, this prior art cannot solve the problem that the endurance of the unmanned aerial vehicle is reduced when it returns along the original route or hovers in the air during the inspection of long-distance transmission cables.
[0005] To sum up, the problems existing in the prior art are as follows: 1. During the inspection of long-distance high-voltage cables in mountainous areas and dense forests, the endurance of the unmanned aerial vehicle is reduced when it returns along the original route or hovers in the air. 2. Adding a protection net to the rotor of the unmanned aerial vehicle increases the wind resistance of the unmanned aerial vehicle and cannot effectively prevent the body of the unmanned aerial vehicle from colliding with the cable.
[0006] In order to solve the problems existing in the above prior art, this case is specifically proposed to solve them. Summary of the Utility Model
[0007] 1. Technical issues to be resolved

The upper shell is fixedly installed above the equipment box, and a hanging assembly is provided on the equipment box. The hanging assembly includes a suspension rod, a first clip, and a servo motor. The suspension rod is L-shaped as a whole. The first clip is inclined and slidably arranged on the suspension rod. A clip position for fixing the cable is formed between the first clip and the suspension rod. The servo motor is connected to the first clip in a transmission manner. The first clip is slidably connected to the suspension rod to fix the cable. The control panel is electrically connected to the servo motor and each non-contact current sensor through wires.
[0011] Optionally, four arms are fixedly mounted on the side walls of the upper shell, and a non-contact current sensor is fixedly mounted on each of the arms.
[0012] Optionally, a rotor motor is fixedly mounted on one end of each of the arms away from the upper shell, and a rotor is fixedly mounted on the output shaft end of the rotor motor.

[0018] (III) Beneficial effects
[0019] The utility model provides a UAV power inspection device, which has the following beneficial effects:
[0020] 1. This UAV power inspection device, through the setting of the hanging component, enables this UAV power inspection device to have the effect of hanging the UAV on the cable to stay and reduce power consumption. When the UAV inspects the high-voltage cable, it is hung on the cable through the hanging component. When the UAV flies to below the cable, the upper end of the hanging rod hooks the cable, and the control board controls the start of the servo motor. The servo motor drives the first clamping strip to move, and the first clamping strip cooperates with the hanging rod to fix the cable buckle in the buckle position, so that the UAV is hung on the cable. Then the UAV stops flying, so that the UAV avoids returning along the original route or hovering in the air, achieving the purpose of saving the power of the UAV and not reducing the endurance due to the UAV returning along the original route or hovering in the air.
[0021] 2. This UAV power inspection device, by setting multiple non-contact current sensors on the arm of the UAV, uses each non-contact current sensor to detect the current in the high-voltage cable. The high-voltage current in the cable generates a magnetic field, and each non-contact current sensor locates and confirms the cable position according to the magnetic field. Thus, the UAV can detect the distance from the cable through multiple non-contact current sensors, so as to ensure a safe distance between the UAV and the cable and avoid collisions between the UAV and the cable.
