All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and/or steps.

Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

As shown in Figure 1 , including the UAV 1 powered by a hydrogen fuel cell, the lower end of the UAV fuselage has a quick release mechanism, and a support plate 9 is arranged at the lower end of the quick release mechanism, and the top of the support plate 9 is rotated and installed by a rotating shaft 15. A support, a shaft rod 16 protrudes from the upper end of the bracket, and a shaft sleeve 8 is movable on the shaft rod 16. One end of the shaft sleeve 8 is connected with the quick release mechanism through a traction rope 6, and the bottom of the support plate 9 is provided with a shaft away from the shaft rod. A roller mechanism, the cable 12 is placed in the fixed cavity 18 opened at the upper end of the support plate 9, and is clamped by the splints 17 on both sides of the inner wall of the fixed cavity.

Wherein, the quick separation mechanism includes a hook 2 arranged at the lower end of the UAV body, and a hanging ring 4 is hung on the hook 2. There is a hanging hole 3 in the middle of the hanging ring 4. The hanging hole 3 is hung on the hook 2, and the traction rope The top of 6 is fixedly connected to the bottom of the hanging ring. By setting the hook 2 structure, after the transportation is completed, the drone moves down and the hanging hole is removed from the hook to complete the separation, which is very convenient.

A first spring 5 is set on the shaft, and the top of the shaft has a limit portion 7 with an outer diameter larger than the shaft, and the bottom of the spring is in contact with the upper end surface of the shaft sleeve. Through the setting of the first spring 5, the problem is effectively solved. The impact of the bumpy road on the UAV can reduce the vibration and make the traction more stable.

In this embodiment, the roller mechanism includes a telescopic sleeve 11, a telescopic rod 13 is inserted into the bottom of the telescopic sleeve 11, and a second spring (not shown) is arranged in the telescopic sleeve 11, and the telescopic rod 13 is in contact with the bottom of the second spring. The bottom of the telescopic rod is provided with a roller 14, and an angle of 45 degrees is formed between the roller mechanism and the support plate. Because it is at a 45-degree angle, it has a very good support angle. No matter the rough road or what kind of road, it can pass normally because it is supported alone. The other end is partially lifted by the drone, and the tail is supported by rollers. It reduces the power consumption of the drone, can pull more cables, and improves the working endurance. Of course, this structure is more suitable for some relatively gentle road sections, and the bumps will be smaller. If you encounter road sections that the rollers cannot pass, You can also choose to take off completely and hold up the entire support plate to separate the rollers from the ground. However, if the remaining road section is good, you can try the semi-traction method again to continue saving power.

As shown in Figure 2, a third spring (not shown) is provided on the inner side of the splint 17, the third spring is embedded in the fixed cavity, and an arc-shaped concave cavity is provided on the opposite surface of the splint, and the two sides of the cable are respectively buckled into the splint The cable is placed in the two arc-shaped cavities, and is automatically clamped by the third spring, which is very convenient for installation and unloading.

The beneficial effects of the present invention are: the present invention is mainly used for the transportation of wires such as cables, and is mainly used in rugged mountain road areas, and realizes rapid traction through the semi-traction of the drone, and the traction device part is in contact with the ground rollers , reduce the power consumption of the UAV, increase the battery life, and realize rapid separation and improve work efficiency.

The above is only a specific implementation of the present invention, but the scope of protection of the present invention is not limited thereto, and any changes or replacements that do not come to mind through creative work shall be covered within the scope of protection of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope defined in the claims.
