Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a tethered lighting UAV. Background Technology

[0002] A tethered lighting drone is a long-endurance UAV platform that operates at high altitudes to illuminate the ground. It consists of a drone, an LED lighting unit, and a tethered power supply system. Powered continuously by the ground-based tethered power supply system, it achieves 24-hour uninterrupted flight and hovering, solving the problem of insufficient endurance of conventional UAVs. This has played a crucial role in emergency situations such as disaster relief, power restoration, and other emergencies.

[0003] A search revealed an existing patent (publication number: CN217649661U) that discloses a high-altitude tethered lighting drone, comprising: a lighting drone body and a drone base, with a cable connecting the lighting drone body and the drone base for supplying power to the drone body; wherein, the drone base includes a power supply base and a drone platform disposed on the upper end of the power supply base, and a cable retraction assembly and a drone lifting assembly are installed on the upper end of the drone platform, with an assembly mounting slot on the right side of the drone platform, and the drone lifting assembly is installed inside the assembly mounting slot. This utility model uses a drone base to fix the drone itself and serve as a takeoff platform for the drone, ensuring smooth takeoff of the drone in complex terrain conditions. At the same time, an electromagnetic adsorption device is set in the drone base to achieve catapult takeoff of the drone in conjunction with a spring. In the takeoff state of the drone, the elastic potential energy of the spring is used to overcome the static inertia of the drone itself, thereby reducing the lift required for vertical takeoff of the drone, increasing the vertical takeoff and landing speed of the drone, and improving the maneuverability of the drone.

[0004] However, drone cables have a certain weight, and during takeoff and landing, they can easily pull on the connectors. Especially when the cables are tangled, if the drone cables are subjected to excessive tension, it can affect the drone's flight and impact its high-altitude operations. Utility Model Content

[0005] Therefore, this utility model provides a tethered lighting drone to solve the above-mentioned problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] According to a first aspect of the present invention, a tethered lighting drone includes a lighting drone body. A U-shaped fixing frame is fixedly connected to one side of the bottom of the lighting drone body. An anti-slip pad is fixedly connected to the inner wall of the U-shaped fixing frame. A lifting groove is formed at the bottom of the lighting drone body directly above the U-shaped fixing frame. A pneumatic telescopic rod is fixedly connected inside the lifting groove. A pressure plate is fixedly connected to the extension end of the pneumatic telescopic rod. An anti-slip pad is fixedly connected to the bottom of the pressure plate. Semi-cylindrical slots are formed on two opposite sides of the anti-slip pad and the anti-slip pad. The upper and lower semi-cylindrical slots can be combined to form a circular... The lighting drone body has two sliding grooves on either side of the center of its bottom. Two sliding grooves are formed on either side of the first sliding groove. A slider is slidably connected inside the first sliding groove, and sliders are fixedly connected to both ends of the first slider. Slider 2 slides within the second sliding groove. A spring telescopic rod and a push switch are fixedly connected to the side of the first sliding groove away from the slider. The extended end of the spring telescopic rod is in contact with the slider. When the spring telescopic rod is shortened to its shortest distance, the protruding length of the push switch is greater than that of the spring telescopic rod. A connecting rod 2 is fixedly connected to the bottom of one slider. A sleeve is fixedly connected to the device, and a turntable is rotatably connected inside the sleeve. A winding rod is fixedly connected to one end of the turntable, and an insertion rod is fixedly connected to the other end of the winding rod. An anti-slip sleeve is fixedly connected to the outside of the insertion rod. A connecting rod is fixedly connected to the bottom of the slider on the other side, and a connecting block is fixedly connected to the bottom of the connecting rod. A winding insert is fixedly connected to the other end of the connecting block. The insertion rod and the anti-slip sleeve are inserted into and rotate inside the winding insert. A cable is wound around the outside of the winding rod and the winding insert. A pneumatic telescopic rod can push the pressure plate downwards, causing the second anti-slip pad and the first anti-slip pad to press against each other. The combination of anti-slip pad 2 and anti-slip pad 1 creates a circular groove that clamps the cable for anti-slip purposes. When subjected to external tension, the circular groove can clamp the cable. When the tension reaches a certain level and clamping is no longer possible, the cable slides inside the circular groove under tension. The cable further pulls the two ends of the winding rod, which are located inside the sleeve and winding insert, respectively, to rotate and release part of the cable. When the maximum cable release length is reached, slider 1 is pulled and moves to press the spring telescopic rod. Pressing the button switch further pauses the drone. The circular groove, anti-slip sleeve, and spring telescopic rod provide multi-layer buffering to cushion the cable tension during the drone's takeoff acceleration.

[0008] Furthermore, flight components are provided at all four corners of the lighting drone body, and shock-absorbing dampers are fixedly connected to all four corners of the bottom of the lighting drone body. Shock-absorbing seats are fixedly connected to the bottom of the shock-absorbing dampers, thereby achieving the shock absorption function for the drone's lift and drop.

[0009] Furthermore, spring telescopic rods are provided on both sides of the push switch, and the extended ends of the spring telescopic rods are in contact with the slider.

[0010] Furthermore, the number of the semi-cylindrical slots is set to multiple, and the multiple semi-cylindrical slots are adapted to clamp multi-layer cables.

[0011] Furthermore, one end of the cable is fixedly connected to a connector, and the other side of the bottom of the lighting drone body is fixedly connected to a plug plate. The connector is inserted into the plug plate, and the cable and the lighting drone body can be directly connected by the plug plate and connector.

[0012] Furthermore, a spring is fixedly connected to one side of the sleeve, and a turntable is fixedly connected to the other end of the spring. The turntable is restricted to rotating inside the sleeve. The sleeve can be configured to rotate the turntable to release the cable after it has been released, thereby enabling the cable to be retrieved.

[0013] Furthermore, the first slide, the second slide, the first slider, and the second slider are all rectangular structures, and the push switch is the hovering control switch for the drone.

[0014] Furthermore, the U-shaped fixing frame and the winding rod are far apart from each other, and the cable is connected to the power supply module on the ground.

[0015] This utility model has the following advantages:

[0016] 1. In this utility model, the pneumatic telescopic rod can push the pressure plate downward, causing the anti-slip pad 2 and anti-slip pad 1 to press against each other. This further causes the circular groove formed by the combination of anti-slip pad 2 and anti-slip pad 1 to clamp the cable and provide an anti-slip effect. When subjected to external tension, the circular groove can clamp the cable. When a certain tension is reached and clamping is no longer possible, the cable slides inside the circular groove under tension. The cable further pulls the two ends of the winding rod, which are located inside the sleeve and winding insert respectively, to rotate and release part of the cable. When the maximum cable length is reached, the slider 1 is pulled and moves to press the spring telescopic rod. Pressing the button switch further pauses the drone. The circular groove, anti-slip sleeve, and spring telescopic rod provide multi-layer buffering to buffer the tension of the cable during the drone's takeoff acceleration.

[0017] 2. In this utility model, the shock-absorbing damping is used to reduce the shock of the drone's lift and drop. The plug and connector can be used to directly connect the cable and the lighting drone body. The sleeve can be used to rotate the turntable to release the cable and then rotate the turntable back to retrieve the cable. Attached Figure Description

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example 1

[0027] like Figures 1 to 6As shown, the tethered lighting drone in the first aspect embodiment of this utility model includes a lighting drone body 1. A U-shaped fixing frame 2 is fixedly connected to one side of the bottom of the lighting drone body 1. An anti-slip pad 3 is fixedly connected to the inner wall of the U-shaped fixing frame 2. A lifting groove 4 is opened at the bottom of the lighting drone body 1 directly above the U-shaped fixing frame 2. A pneumatic telescopic rod 5 is fixedly connected inside the lifting groove 4. A pressure plate 6 is fixedly connected to the extension end of the pneumatic telescopic rod 5. An anti-slip pad 7 is fixedly connected to the bottom of the pressure plate 6. Semi-cylindrical slots are opened on the two opposite sides of the anti-slip pad 3 and the anti-slip pad 7. The upper and lower semi-cylindrical slots can be combined to form a circular groove. A sliding groove 8 is opened on both sides of the middle position of the bottom of the lighting drone body 1. A sliding groove 9 is opened on both sides of the sliding groove 8. A slider 10 is slidably connected inside the sliding groove 8. A slider 11 is fixedly connected to both ends of the slider 10. The slider 11 slides inside the sliding groove 9. A spring telescopic rod 22 and a push switch 23 are fixedly connected to the side away from slider 10. The extended end of the spring telescopic rod 22 is in contact with slider 10. When the spring telescopic rod 22 is shortened to its shortest distance, the protruding length of the push switch 23 is greater than that of the spring telescopic rod 22. A connecting rod 20 is fixedly connected to the bottom of slider 10 on one side. A sleeve 19 is fixedly connected to the bottom of the connecting rod 20. A turntable 18 is rotatably connected inside the sleeve 19. A winding rod 17 is fixedly connected to the other end of the turntable 18. An insertion rod 15 is fixedly connected to the other end of the winding rod 17. An anti-slip sleeve 16 is fixedly connected to the outside of the insertion rod 15. A connecting rod 12 is fixedly connected to the bottom of slider 10 on the other side. A connecting block 13 is fixedly connected to the bottom of the connecting rod 12. A winding insert 14 is fixedly connected to the other end of the connecting block 13. The insertion rod 15 and the anti-slip sleeve 16 are inserted into the inside of the winding insert 14 and rotate. Cables are wound around the outside of the winding rod 17 and the winding insert 14.

[0028] The pneumatic telescopic rod 5 can push the pressure plate 6 downward, causing the anti-slip pad 2 7 and anti-slip pad 1 3 to press against each other. This further enables the circular groove formed by the combination of anti-slip pad 2 7 and anti-slip pad 1 3 to clamp the cable and provide anti-slip function. When subjected to external tension, the circular groove can clamp the cable. When a certain tension is reached and clamping is no longer possible, the cable slides inside the circular groove under tension. The cable further pulls the two ends of the winding rod 17, which are located inside the sleeve 19 and the winding insert 14 respectively, to rotate and release part of the cable. When the maximum cable release length is reached, the slider 10 is pulled and moves to press the spring telescopic rod 22. The press switch 23 is then pressed to perform an emergency stop for the drone. The multi-layer buffering of the circular groove, anti-slip sleeve 16, and spring telescopic rod 22 can buffer the tension of the cable during the drone's takeoff acceleration.

[0029] In this embodiment, shock-absorbing dampers 26 are fixedly connected to the four corners of the bottom of the lighting drone body 1, and shock-absorbing seats 21 are fixedly connected to the bottom of the shock-absorbing dampers 26.

[0032] In this embodiment, multiple semi-cylindrical slots are provided, and multiple semi-cylindrical slots are adapted to clamp multi-layer cables.

[0033] Example 2

[0034] like Figures 1 to 6 As shown, the tethered lighting drone includes all the contents of Embodiment 1. One end of the cable is fixedly connected to a connector, and the other side of the bottom of the lighting drone body 1 is fixedly connected to a plug plate 24, with the connector plug inserted into the interior of the plug plate 24.

[0035] The cable and the lighting drone body 1 can be directly connected via the set-in plug 24 and wiring plug.

[0036] In this embodiment, a spring is fixedly connected to one side inside the sleeve 19, and a turntable 18 is fixedly connected to the other end of the spring. The turntable 18 restricts the internal rotation of the sleeve 19.

[0037] The sleeve 19 allows the turntable 18 to rotate back after it has been used to feed the cable, thus enabling the cable to be retrieved.

[0038] In this embodiment, slide 8, slide 9, slider 10 and slider 21 are all rectangular structures, and the push switch 23 is the hovering control switch for the UAV.

[0039] In this embodiment, the U-shaped fixing frame 2 and the winding rod 17 are far apart from each other, and the cable is connected to the power supply module on the ground.

[0040] The technical effects achieved by the above embodiments are as follows: the pneumatic telescopic rod 5 presses down on the pressure plate 6, causing the anti-slip pad 2 7 and the anti-slip pad 1 3 to press against each other, further enabling the circular groove of the anti-slip pad 2 7 and the anti-slip pad 1 3 to clamp the cable and provide anti-slip function. When subjected to external tension, the circular groove can clamp the cable. When a certain tension is reached and clamping is no longer possible, the cable slides inside the circular groove under tension. The cable further pulls the two ends of the winding rod 17 to rotate inside the sleeve 19 and the winding insert 14 respectively to release part of the cable. When the maximum cable length is reached, the slider 10 is pulled and moves to press the spring telescopic rod 22. The press switch 23 is then pressed to perform an emergency stop for the drone. The circular groove, the anti-slip sleeve 16, and the spring telescopic rod 22 provide multi-layer buffering to buffer the tension of the cable during the drone's takeoff acceleration.
