Description

Technical Field

[0001] The utility model relates to the technical field of tethered drone equipment, in particular to a drone tethering device capable of automatically retracting and releasing a line. Background Art

[0002] A tethered drone is a drone system that combines a drone and a tethered integrated cable. The tethered drone transmits electrical energy through an optoelectronic integrated cable, allowing the drone to stay in the air for a long time without being restricted by electrical energy. Its structure size and manufacturing materials can be flexibly designed according to application requirements, and it has strong maneuverability. According to different application scenarios, the tethered drone system is divided into ground fixed, vehicle-mounted mobile and ship-mounted mobile. The three working modes meet the needs of various working environments very well.

[0003] Currently, most of the existing tethered drone retractable and retractable devices are manually operated, which requires separate manpower and is cumbersome. The manual retractable speed must be greater than or equal to the drone's ascent speed. When retracting the cable, the drone's descent speed is greater than the manual retractable speed, and a large amount of cable will be stranded. The stranded cable is easy to get tangled and knotted, which poses a great risk to the destructiveness and safety of the cable. In addition, most retractable and retractable devices are fixed and cannot be moved.

[0004] The existing patent (Announcement No.: CN209815411U) discloses that the winding device is driven to rotate by a transmission shaft, and the controller is convenient for adjusting the rotation speed. The utility model can be moved through the roller, which solves the problem that the current tethered drone reeling and releasing device still needs manual reeling and can only be fixed and cannot be moved.

[0005] However, the above technical solution still has certain defects. Firstly, when the device is winding up the wire, the wire may be concentrated in one area and continuously wound up, and the accumulation may eventually lead to falling off, affecting the winding efficiency and winding quality. Secondly, the bottom of the device is connected to the roller through a groove, so the strength is too low, and it may collapse when moving, and the installation is cumbersome and time-consuming. Therefore, a drone tethering device that can automatically reel in and release the wire is proposed. Utility Model Content
