[0002] In emergency rescue and major event support, it is necessary to conduct full-process information monitoring and information assurance on site. It is often impossible to find a suitable installation platform on site. Based on the large-load UAV platform, it is possible to mount equipment such as aerial lighting, communication relay, environmental monitoring, and on-site surveillance to meet the comprehensive information assurance of emergency rescue and disposal at the scene of the emergency. However, the flight time of large-load UAVs is generally about 30 minutes, which cannot meet the continuous work requirements of long-term hovering in the air. The tethered power supply equipment on the market is currently mainly for small UAVs, and the load capacity is generally less than 2 kilograms, which cannot meet the mounting requirements of actual emergency equipment. In order to meet the information assurance requirements of the emergency site, it is urgent to develop a large-load UAV tethered power supply equipment to meet the mounting needs of multi-task payloads such as floodlights, spotlights, high-pitched loudspeakers, aerial hoist systems, and communication base stations at the emergency site.

[0003] When the existing tethered cable is connected to a drone, the tethered cable needs to be transported during the ascent of the drone to ensure the flying height of the drone.

[0025] Reference Figure 1-Figure 5 A tethered power supply device for a large-load unmanned aerial vehicle includes a tethered power supply device for supplying power to the unmanned aerial vehicle from the ground. The tethered power supply device includes three units: a tethered box power supply 1, an onboard power supply 2, and a tethered cable 7. The tethered box power supply 1 has an onboard power supply 2 installed inside it. Cooling fans 3 are arranged on both sides of the tethered box power supply 1. The front of the tethered box power supply 1 is rotatably connected to a cabinet door 4 through a hinge. The front of the cabinet door 4 is respectively fixedly connected to a threaded rod 5 and a cross bar mechanism 8. The cross bar mechanism 8 is located directly above the threaded rod 5. A rotating drum 6 is sleeved on the surface of the threaded rod 5. The surface of the rotating drum 6 is wrapped with a tethered cable 7. The end of the tethered cable 7 passes through the cabinet door 4 and is electrically connected to the transmission end of the tethered box power supply 1. The interior of the cross bar mechanism 8 is rotatably connected to a sliding mechanism 9. The sliding mechanism 9 is used to limit the surface of the tethered cable 7.

[0026] In the utility model, when in use, the mooring box power supply 1 is first placed in the working area, and then the onboard power supply 2 is installed inside the mooring box power supply 1 for charging, and the cooling fan 3 is used to cool the inside of the mooring box power supply 1, so as to provide a power transmission environment for the onboard power supply 2. At this time, the rotating drum 6 is installed on the threaded rod 5, and the mooring cable 7 on the rotating drum 6 is electrically connected to the mooring box power supply 1, and at the same time, the other end of the mooring cable 7 is connected to the large-load UAV. Under the setting of the crossbar mechanism 8, it can guide and limit the sliding mechanism 9, and then the sliding mechanism 9 is used to limit the surface of the mooring cable 7, so that the mooring cable 7 can be straightened, so as to ensure the power transmission efficiency.

[0027] Supplementary explanation: The tethered box power supply 1 is also provided with an AC switch, a high-voltage on-off button, a tether cable forced collection button and other buttons to control the tethered box power supply 1; the tethered cable 7 is an optoelectronic composite cable, which contains a tightly wrapped optical fiber cable and a power cable. The power cable adopts an alloy lightweight and high-temperature resistant aviation line, a composite fluoroplastic insulation layer, and a high-modulus tensile aviation-grade fiber braided layer. The cable current carrying capacity is 25-30A and the length is 330 meters; the airborne power supply 2 has a wide input voltage range of 580-810Vdc, an output voltage of 59Vdc±1%, and a constant regulated output. It can support voltage customization to adapt to different types of large-load UAVs. The installation method is to replace an airborne power supply 2, which can be directly plugged in and installed on the UAV.

[0028] Reference Figure 1 and Figure 2 The sliding mechanism 9 includes a sliding frame 91 that slides inside the cross bar mechanism 8, and support blocks 92 are fixedly connected to both sides of the sliding frame 91. A sliding rod 93 is slidably connected inside the support block 92, and a concave frame 94 is fixedly connected to the end of the sliding rod 93. The inner side of the concave frame 94 is rotatably connected to a limiting roller 95 through a rotating shaft.

[0029] In the utility model, the crossbar mechanism 8 is used to limit the sliding frame 91, and then the sliding rod 93 inside the support block 92 on the sliding frame 91 is stretched outward, so that the spacing between the concave frames 94 is increased, so as to facilitate the installation of the mooring cable 7 between the limiting rollers 95. At this time, the concave frame 94 is reset to fit the limiting rollers 95 on the surface of the mooring cable 7, so that it can be rolled and straightened during the stretching process of the mooring cable 7, thereby preventing the mooring cable 7 from bending and affecting the power transmission efficiency.

[0030] Reference Figure 2 The end of the sliding rod 93 is sleeved with a return spring 96, and the two ends of the return spring 96 are respectively connected to the support block 92 and the sliding rod 93.

[0031] In the present invention, the repulsive force of the reset spring 96 can provide a pulling force to the sliding rod 93, thereby automatically resetting the concave frame 94, so that the limiting roller 95 can be attached to the surface of the mooring cable 7 for rolling straightening.

[0032] Reference Figure 2 A ball 97 is provided at the end of the sliding frame 91, and the ball 97 rolls inside the crossbar mechanism 8.

[0033] In the present invention, the balls 97 roll inside the crossbar mechanism 8 , so that the sliding frame 91 can further improve the smoothness of movement inside the crossbar mechanism 8 .

[0034] Reference Figure 3 The crossbar mechanism 8 includes a crossbeam 81 fixed to the front of the cabinet door 4, and a guide groove 82 is provided inside the crossbeam 81. The guide groove 82 is used to limit the sliding frame 91 and the ball 97 respectively.

[0035] In the present invention, the guide groove 82 is provided inside the crossbeam 81 so as to limit the position of the sliding frame 91 and the ball bearing 97, thereby ensuring the guiding performance of the sliding frame 91 and the support block 92 when moving.

[0036] Reference Figure 3 A blocking block 83 is embedded in the guide groove 82 and is located at the end of the crossbeam 81 .

[0037] In the present invention, the blocking block 83 is provided to block the end of the crossbeam 81 , thereby preventing the sliding mechanism 9 from falling off in the crossbar mechanism 8 .

[0038] Reference Figure 4 The surface of the threaded rod 5 is threadedly connected with a limiting nut 10, and the limiting nut 10 is used to limit the end of the rotating drum 6.

[0039] In the present invention, the limiting nut 10 is threadedly connected to the surface of the threaded rod 5, so that the end of the rotating drum 6 can be limited to prevent the rotating drum 6 from falling.

[0040] Reference Figure 4 and Figure 5 A limit lever 11 is connected to the interior of the threaded rod 5 , and the limit lever 11 is used to limit the limit nut 10 .

[0041] In the present invention, the limit lever 11 is set so that it can penetrate the inside of the threaded rod 5, so as to limit the limit nut 10 and prevent the limit nut 10 and the threaded rod 5 from falling off.

[0042] In addition, the limit lever 11 is composed of two threaded caps and a fixed rod. There are threaded grooves at both ends of the fixed rod, and the threads are convenient for connecting the threaded caps. When disassembling the limit lever 11, only one of the threaded caps needs to be removed to separate the limit lever 11 and the threaded rod 5.
