Embodiment 1

[0034]Such asFigures 1 to 10 As shown, the present invention provides a drone that detects the fault of the power cable, including the body 1, the arm 2, and a drive motor 3 with paddle 30, the arm 2 is four, four machine arm 2 The symmetrical hinges are hinged to the body 1, and the drive motor 3 is provided at the end of the arm 2, the drive motor 3 can be positive inversion; the body 1 is provided with a exhibition device, and the exhibition device is connected to the end of the arm 2 to pass through The exhibition device controls four arm 2 together to perform the exhibition movement, thereby adjusting the deployment width of the arm 2; the lower end of the drive motor 3 can be rotated with a roller 4, and the roller 4 is passed through the transmission assembly and the drive motor 3 output. The drive is connected so that the drive motor 3 is rotated by the transmission assembly to rotate to travel on the high voltage cable; the roller 4 is provided with a roller groove 41 in th...

Embodiment 2

[0042]Such asFigure 5 ,Figure 7 And andFigure 9 As shown in connection with the technical solution of Example 1, in the present embodiment, the pulley 53 assembly includes a tab rod 51, a V-shaped member 52, a pulley 53, a tie rod 54, and a ring semi-circular plate 55, and the tab 51 can be driven by the drive motor 56. The rotation is provided in the body 1, and the V-shaped member 52 is hinged on the arm 2, and the annular semi-circular plate 55 is provided between the annular restricted member 6, and the ring restricted member 6 is connected to one end of the V-shaped member 52 by the lever 54, v. The other end of the sheet 52 is connected to the tab 51 by the pull line 53 to rotate one end of the V-shaped member 52 by the pull line 53, so that the other end of the V-shaped member 52 is rotated to drive the tie rod 54 to rise. Where the V-shaped member 52 is two plate structures, one end is an opening structure, and the tie rod 54 is opened in the V-shaped member 52 via a limit p...

Embodiment 3

[0047]Such asFigure 1 to 8As shown in connection with the technical solution of Example 2, in the present embodiment, the cross section of the roller groove 41 is a U-shaped structure, and the roller groove 41 of the U-shaped structure can increase the contact area of ​​the roller 4 and the high voltage cable, thereby reducing high pressure. The impact of the cable swaying on the roller 4, thereby reducing the problem that the drone causes detachment caused by high voltage cable shaking.

[0048]By providing the elastic limit piece 5 in the roller 4 in the roller 4, the roller 4 can be limited to the roller 4 by the elastic limit member 5 during the rotation of the roller 4 to rotate on the high voltage cable. The cable is caused by the problem of the wind swing causes the roller 4 to disengage the high voltage cable; the roller 4 drives the elastic limit piece 5 and the high voltage cable in the process, so that the elastic limit piece 5 follows the roller 4 to move to high pressure O...

Abstract

The invention discloses an unmanned aerial vehicle for detecting power cable faults. Rollers are arranged at the end parts of vehicle arms, so that the unmanned aerial vehicle can be limited between high-voltage cables through the rollers, the weight of the unmanned aerial vehicle is shared through the high-voltage cables, the rotating speed of blades of the unmanned aerial vehicle is reduced, andthe cruising ability of the unmanned aerial vehicle is effectively improved; the unmanned aerial vehicle ascends and descends through the blades and then is in rolling connection with a high-voltageline through the rolling wheels, and the inspection efficiency is effectively improved; meanwhile, a folding and unfolding device is arranged in the machine body to fold and unfold the multiple machine arms on the machine body, so that the folding and unfolding areas of the machine arms are adjusted to adapt to roller walking on high-voltage cables with different intervals; by adjusting folding and unfolding of the vehicle arms, when the unmanned aerial vehicle goes uphill and downhill from the high-voltage cable from high to low, the unfolding width of the vehicle arms can be controlled through the folding and unfolding device to increase the friction force between the rolling wheels and the high-voltage cable so as to reduce the downhill speed, and the problem of downhill diving of the unmanned aerial vehicle in the walking process is effectively solved.

Description

Technical field[0001]The present invention relates to the field of cable detection, in particular a drone that detects the failure of the power cable.Background technique[0002]The island-type grid is seriously affected by typhoons, lightning strikes, and salty erosion, and the net airlines are easy to aging, and the lane corridors are harsh, and it is easy to trigger a line failure. At present, the distribution line inspection mainly adopts artificial observation of thermal imaging and other technologies, there are several problems in actual work. The first is that the hidden dangers are difficult to find that the mainly used naked eye, telescope observation and thermal imaging technology have small detection range, and is susceptible to external conditions; secondly, it is difficult to identify, and the current technology can only identify and divide small partial hidden tribute types. The type of hidden dangers in the device appearing in the discharge cannot be distinguished, the ...
