Embodiment 1

[0043] Refer to attached Figure 1-10 As shown, the present invention provides a technical solution: a power transmission line safety inspection system with obstacle avoidance function, including a drone 100 and a mounting device 200;

[0044] Refer to attached Figure 3-4 As shown, the top plate 110 of the drone 100 is provided with a mounting groove 111, and the mounting groove 111 is arranged in an I shape. The inside of the top plate 110 is a hollow structure, and an accommodation cavity 112 is provided inside it. connected.

[0045] Refer to attached Figure 1~3 As shown, the top plate 110 is located on both sides of the installation groove 111 and the bottom of the drone 100 is equipped with a multi-angle camera 130 .

[0046] The multi-angle camera 130 is used to collect the image information of the transmission line during the inspection process, and through the analysis of the obtained image information, it can be known whether the transmission line is damaged; of ...

Embodiment 2

[0064] Refer to attached Figure 11 As shown, an embodiment of the present invention further provides a power transmission line safety inspection method with obstacle avoidance function, including the following steps:

[0065] S1, opening and closing of the walking arm 210: use the remote controller to send execution instructions to the controller 121 through the signal transceiver 123, and the controller 121 controls the fourth driving motor 227 to energize and drive the second rotating shaft 226 and the second bevel gear 225, so that the second bevel gear The gear 225 drives the two first bevel gears 223 to rotate in reverse, so that the two screw mandrels 221 can follow the reverse rotation, and then the two threaded sleeves 224 tend to move away from each other, and the two connecting rods 228 are connected with the corresponding The screw rod 221 produces a larger included angle, so it can drive the two walking arms 210 vertically in the installation groove 111;

Abstract

The invention belongs to the technical field of power line inspection, and provides a power transmission line inspection system which comprises an unmanned aerial vehicle and a mounting device installed on the upper portion of the unmanned aerial vehicle, the mounting device comprises an opening and closing mechanism and two or more walking arms, the walking arms are hinged to the unmanned aerial vehicle, and the opening and closing mechanism is arranged in the unmanned aerial vehicle and can drive the walking arms to rotate around hinge shafts; each walking arm is formed by hinging an upper power-assisted arm and a lower power-assisted arm, two walking wheels are arranged at the top of the upper power-assisted arm, and the wheel center distance of the two walking wheels is adjustable, the device finds obstacles through a visual system of the unmanned aerial vehicle, and a built-in chip of the unmanned aerial vehicle drives the opening and closing mechanism and the walking arm to complete multi-angle actions; the walking arms used for being mounted on the same unmanned aerial vehicle are sequentially off-line in front of the obstacle and then sequentially on-line after passing through the obstacle. The routing inspection step is the routing inspection method for the power transmission line provided by the invention, and is suitable for routing inspection of field long-distance power supply lines.

Description

technical field [0001] The invention belongs to the technical field of power line inspection, and in particular relates to a transmission line inspection system and method. Background technique [0002] With the rapid expansion of my country's power grid structure and the rapid development of social economy, the demand for electricity in human production and life has increased sharply and the quality of power supply has become higher. The transmission lines of the power grid are also moving towards "long-distance, large-scale, and large-scale" direction continues to move forward. In the overhead transmission line project, the construction cost of the transmission line accounts for about one-third of the total investment of the transmission project, or even more, which directly determines whether the power grid can have good economic benefits. Since my country's transmission lines are mostly erected in remote areas and exposed to the wild for a long time, there is always a po...
