Example Embodiment

[0032] Example 1:

[0033] Such as figure 1 with figure 2 As shown, a power transmission line inspection robot based on an unmanned aerial vehicle platform includes a four-rotor unmanned aerial vehicle body 1, which has a channel 2 through up and down in the middle of the four-rotor unmanned aerial vehicle body 1. A supporting board 4 is suspended at the bottom of the main body 1 through a plurality of supporting rods 3, and a transmission line running mechanism is arranged on the supporting board 4.

[0034] The transmission line walking mechanism includes a vertical electric telescopic rod 5 arranged on the carrying plate 4, the upper end of the vertical electric telescopic rod 5 extends from the channel 2, and the upper end of the vertical electric telescopic rod 5 is arranged The U-shaped driving wheel frame 6 with the opening facing upward, the U-shaped driving wheel frame 6 is rotatably provided with a driving roller 7 which is driven by a stepping motor 8, and the upper par...

Example Embodiment

[0037] Example 2:

[0038] Such as image 3 As shown, the difference from Embodiment 1 is that a pair of fixed pulleys 17 are symmetrically arranged at the bottom of the U-shaped driving wheel frame 6 and located on both sides of the vertical electric telescopic rod 5. The bearing plate 4 is located on An electric cord reel 18 is provided at a position directly below one fixed pulley 17, a fixed ring 19 is provided on the bearing plate 4 and at a position directly below the other fixed pulley 17, and a pull cord 20 is wound on the electric cord reel 18 , The end of the pull wire 20 passes through a fixed pulley 17 directly above the electric cord reel 18, a threading hole 21 opened on the vertical electric telescopic rod 5, and a fixed ring 19 directly The upper fixed pulley 17 is fixed on the fixed ring 19 through the tension sensor 22, and the tension sensor 22 and the electric reel 18 have the flight control system in the quadrotor drone body 1 to realize automatic control . ...

Example Embodiment

[0040] Example 3:

[0041] Such as Figure 4 As shown, the difference from Embodiment 2 is that the two opposite vertical surfaces of the truncated cones 15 are connected to each other through the plug-in rod structure b.

[0042] In this embodiment, in order to make the two truncated cones abut against each other under the telescopic action of their respective horizontal electric telescopic rods to form a stable and complete driven roller, the two truncated cones are inserted between the opposite facades. The connection is realized by a hole inserting rod structure. The socket inserting rod structure can be used to open a jack on one of the truncated cones and set a rod matching the jack on the other truncated cone. Of course, it can also be used in one of the truncated cones. An inserting rod is arranged on the upper side, and a jack matched with the inserting rod is arranged on the other truncated cone.

Abstract

The invention discloses a transmission line inspection robot based on a UAV (unmanned aerial vehicle) platform. The transmission line inspection robot comprises a four-rotor UAV body. The middle of the four-rotor UAV body has a vertical through passage, a carrying board is suspended at the bottom of the four-rotor UAV body through multiple support rods, and the carrying board is provided with a power line walking mechanism. The power line walking mechanism comprises a vertical electric telescopic rod disposed on the carrying board, an upper end of the vertical electric telescopic rod extends out of the passage, the upper end of the vertical electric telescopic rod is provided with a U-shaped driving wheel frame with an upward opening, a driving roller is arranged in the U-shaped driving wheel frame, and the driving roller is driven by a stepping motor. According to the invention, for a long-distance power transmission cable, the inspection robot can be hooked on the power transmissioncable by using the specific power transmission line walking mechanism and the flight inspection can be carried out along the power transmission cable, the time, range and efficiency of the UAV inspection are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of power transmission line inspection equipment, and in particular relates to a power transmission line inspection robot based on an unmanned aerial vehicle platform. Background technique [0002] Overhead transmission lines are generally several kilometers to hundreds of kilometers long. In such a narrow and long range, the line equipment is exposed to the natural environment for a long time and is subjected to various climatic conditions (such as storms, floods, ice and snow freezing, clouds, pollution, lightning strikes, etc.); Other external force damage (such as farmland farming machinery hitting pole towers or cable foundations, falling trees and bamboos colliding with wires, construction and construction near the line, mountain blasting, shooting, passing vehicles and cranes breaking wires, kites hanging on wires and causing phase-to-phase short circuit , grounding short circuit caused by birds and b...
