Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] like Figure 1 , Figure 2 As shown, a power transmission line inspection drone includes a drone body 1. Four connecting posts 2 are bolted in a rectangular array on the lower side of the drone body 1. A mounting plate 3 is bolted to the lower side of the four connecting posts 2. A camera 4 is bolted to the lower side of the mounting plate 3. A mounting frame 5 is bolted to the upper side of the mounting plate 3. An upper cavity 502 and a lower cavity 501 are vertically arranged within the mounting frame 5 via a partition 6. The upper cavity 502 is located above the lower cavity 501. Two first telescopic tubes 7 are symmetrically arranged left and right within the lower cavity 501. The upper side of the first telescopic tubes 7 is aligned with the lower side of the partition 6. The first telescopic tube 7 is connected to the second telescopic tube 8 by means of a sealing gasket, a slider and a groove. The lower side of the second telescopic tube 8 passes through the mounting plate 3 and is flush with the lower side of the mounting plate 3. The inner side of the first telescopic tube 7 is provided with a heating wire 9. Two small air pumps 10 are symmetrically installed in the upper cavity 502 by bolts. The air supply end of the two small air pumps 10 is respectively sealed and inserted into the two first telescopic tubes 7 by a sealing gasket. The air inlet end of the small air pumps 10 passes through the mounting bracket 5 and communicates with the outside. The outer side of the second telescopic tube 8 is provided with multiple air jet holes 801 facing the camera 4.
[0018] The upper cavity 502 is equipped with two sets of lifting components that drive the two second telescopic tubes 8 to move up and down respectively.
[0019] The drone body 1 is equipped with an inspection module electrically connected to camera 4. The inspection module includes an inspection module that can detect damage to the surface of the power transmission line, high-temperature areas, and the environment near the towers, and will alarm for abnormalities. The adaptive inspection module can adaptively collect flight paths, and its operation is simple, convenient, and quick to learn. It also has an AI-assisted photo-taking function, which can effectively improve the identification of defects. The adaptive line-following flight module uses radar ranging to ensure that the drone always maintains a safe distance from the power transmission line towers. The power transmission adaptive inspection module can realize functions such as automatic measurement of towers, automatic tower location within the camera range, automatic flight path planning by front-end vision, tower-circling flight, autonomous drone supervision, personnel tracking, and behavior analysis. All of the above functions are reflected in this technical field (and can be achieved by adding different functional devices or systems), so they will not be described in detail here.
[0020] In this embodiment, the lifting assembly includes an electric telescopic rod 13 that is bolted into the upper cavity 502. A connecting plate 14 is welded to the outer side of the upper end of the second telescopic tube 8. The output end of the electric telescopic rod 13 passes through the partition 6 and is connected to the upper side of the connecting plate 14.
[0021] In this embodiment, two dustproof nets 12 are symmetrically installed on the left and right sides of the mounting plate 3 by bolts, and the air inlet of the small air pump 10 is located inside the dustproof nets 12.
[0022] In this embodiment, a power supply 11 and a controller 15 are installed in the upper cavity 502 by bolts. The electric telescopic rod 13, the small air pump 10 and the heating wire 9 are all electrically connected to the power supply 11. The controller is model ESP32. This model of controller has both Wi-Fi and Bluetooth modes, supports DIY wireless control, is suitable for programming users, and has strong expandability.
[0023] In this embodiment, the heating wire 9 is spiral in shape.
[0024] The working principle of this technical solution is as follows: When fog forms on the surface of the camera 4, the operator controls two electric telescopic rods 13 to push two second telescopic tubes 8 downwards to extend the mounting plate 3. Subsequently, the operator controls two small air pumps 10 to supply air into the first telescopic tube 7. At the same time, the heating wire 9 can heat the air inside the first telescopic tube 7. The heated air can be sprayed out onto the surface of the camera 4 through the air jet holes 801 on the surface of the second telescopic tube, eliminating the water fog on the surface of the camera 4 and ensuring the shooting effect of the camera 4. Meanwhile, the dustproof net 12 can prevent impurities in the air from entering the small air pump 10, ensuring the reliability of the small air pump 10 during use.
[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
