Description

Technical Field

[0001] The present invention relates to the field of electric power inspection devices, and in particular to an unmanned aerial vehicle for electric power inspection. Background Art

[0002] The maintenance operation mode of the power system refers to the operation mode of the main equipment in the power system during maintenance. The maintenance inspection of the power grid plays an important role in the normal power supply operation of the main power grid of the power system. The traditional manual inspection method is not only time-consuming and labor-intensive, but also difficult to cover all complex and hard-to-reach areas, such as high mountains and cross-river transmission lines. With the rapid development of drone technology, the use of drones for power inspection has become an efficient and safe alternative. Drones are equipped with high-definition cameras and can conduct detailed inspections of key facilities such as power lines and substations at close range and from multiple angles. In actual applications, when drones fly in complex outdoor environments, the camera lens is easily affected by factors such as dust. Dust often gradually adheres to the lens surface during the flight of the drone, forming obstructions or scattered light, making it inconvenient to remove dust from the camera, resulting in blurred or distorted power inspection images collected, seriously affecting the accuracy and reliability of the inspection results.

[0031] By setting the inclined groove 44, the spiral groove 45 and the guide rod 46, the inner wall of the inclined groove 44 is squeezed when the guide rod 46 reaches the inner cavity of the inclined groove 44, so that the support tube 40 rotates, and then the camera 2 rotates forward, and the front side of the camera 2 moves upward to adjust its angle.

By setting the first spring 411, tension is generated on the round block 412, so that the round block 412 drives the insertion rod 413 to extend into the inner cavity of the socket 410, thereby fixing the positioning tube 49 and the camera 2, thereby improving the stability of the camera 2.

[0032] A first connecting rope 414 is connected between the two round blocks 412, and a second connecting rope 415 is connected to the surface of the first connecting rope 414.

By setting the electric push rod 311, the drive disk 310 and the semicircular tube 39, the semicircular tube 39 can be driven to rotate, thereby driving the camera 2 to rotate. The rotation angle of the camera 2 can be adjusted to facilitate monitoring and inspection of different positions, thereby improving the flexibility of the camera 2.

[0042] A guide rod 312 is connected to the surface of the semicircular tube 39, and a third spring 313 is sleeved on the surface of the guide rod 312. One side of the third spring 313 is connected to the semicircular tube 39, and the other side of the third spring 313 is connected to a guide plate 314.

By setting the third spring 313, tension is generated on the semicircular tube 39 to facilitate the return of the semicircular tube 39.

[0044] Example 3 further optimizes the power inspection drone provided in Example 1 or 2. Specifically, Figure 5 As shown, a special-shaped block 317 is provided on the inner wall of the semicircular tube 39 , a telescopic cover 318 is connected to the surface of the semicircular tube 39 , a fixing plate 319 is connected to the side of the telescopic cover 318 away from the semicircular tube 39 , and the bottom of the fixing plate 319 is connected to the flat plate 421 .

[0045] By setting the cooperation between the special-shaped block 317 and the driving disk 310, the driving disk 310 squeezes the special-shaped block 317 to separate the two special-shaped blocks 317, and then the two semicircular tubes 39 separate and squeeze the telescopic cover 318, transporting the liquid in the inner cavity of the telescopic cover 318, allowing the liquid to enter the dust removal cotton 31, wet wipe the lens of the camera 2, and achieve a better dust removal effect.

[0047] By setting a second one-way liquid outlet valve 320, the discharge of liquid from the inner cavity of the telescopic cover 318 is facilitated. By setting a one-way liquid inlet valve 323, when the telescopic cover 318 is stretched and restored, gas is transported to the inner cavity of the telescopic cover 318 to keep the inner cavity of the telescopic cover 318 and the external air pressure balanced. At the same time, it is convenient to connect with an external filling pipe to add water to the inner cavity of the telescopic cover 318. By setting a frame 322, the inner wall of the telescopic cover 318 is supported, and the telescopic cover 318 is kept in an expanded state when the telescopic cover 318 is stretched and restored.

[0048] The use process of the power inspection drone provided by the present invention is as follows: S1. Heat dissipation: The linear motor 42 is controlled by a wireless remote controller to drive the two drive seats 48 to move closer to and away from each other. The drive seat 48 drives the vertical plate 47, the drive tube 41 and the guide rod 46 to move. The guide rod 46 moves laterally in the inner cavity of the transverse groove 43. When the two drive tubes 41 are closer to each other, the pressure in the inner cavity of the support tube 40 increases, so that the first one-way air intake valve 418 is opened, and the gas in the inner cavity of the support tube 40 enters the inner cavity of the camera 2. The hot air in the inner cavity of the camera 2 is squeezed out through the heat dissipation net 5, which speeds up the heat dissipation efficiency of the camera 2.
