Description

Technical Field

[0001] The present invention relates to the technical field of power grid inspection, and in particular to a laser-excited reflective lighting UAV. Background Art

[0002] Lighting drones are a new type of equipment that uses drones to carry lamps for lighting. They have gradually begun to be widely used in power grid inspection operations because of their advantages such as improving inspection efficiency, breaking through terrain restrictions, enhancing safety, intelligence and multi-functions, as well as high efficiency, energy saving and environmental protection.

[0003] At present, common lighting drones used in power grid inspections include tethered lighting drones and self-lighting drones. Tethered drones need to be connected to ground power lines, which poses safety issues; self-lighting drones have their own lights that consume the drone's energy, reducing the drone's flight time and the lighting time. Summary of the invention

[0004] The purpose of the present invention is to provide a laser-stimulated reflective lighting drone, whose lighting power supply does not require ground power supply lines and does not rely on the drone's electrical energy, thereby increasing lighting time and improving operation safety.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A laser-excited reflective lighting UAV comprises a UAV, a reflective device mounted on the UAV and a laser emitting device arranged on the ground, wherein the reflective device comprises a concave reflector, the laser emitting device shines laser light onto the reflector, and the reflector projects the received light downward to a ground area that needs to be illuminated.

[0007] Preferably, the light reflecting device comprises a Fresnel lens, and the Fresnel lens is located below the reflector. The laser reflected by the reflector irradiates the Fresnel lens, so that the light irradiated to the ground is a 60° uniform light area.

[0008] Furthermore, the Fresnel lens is arranged at the bottom of the reflective device through a lens frame, and a gap is arranged between the lens frame and the reflector. The laser emitted by the ground laser emitter can pass through the gap between the lens frame and the reflector, thereby irradiating the reflector.

[0009] Preferably, the reflective device further comprises an adjusting mechanism for adjusting the angle of the reflector, so that the reflector can adjust the angle of receiving laser light, thereby achieving a better reflective effect.

[0010] Furthermore, the adjustment mechanism includes a bracket, a first servo motor with a controller fixed on the bracket, a first gear driven by the first servo motor, and a second gear meshing with the first gear and fixedly connected to the reflector; the reflector is rotatably connected to the bracket, and the rotation axis of the reflector is horizontal.

[0011] Furthermore, the second gear is a half gear, both ends of which are respectively fixed to the back of the reflector, and the diameter of the half gear is perpendicular to the rotation axis, so that the adjustment of the reflector is limited to a certain range to prevent the reflector from being over-adjusted and hitting the drone.

[0012] Furthermore, the adjustment mechanism also includes a second servo motor with a controller, and the second servo motor drives the bracket to rotate, and the axis of rotation of the bracket passes through the center point of the reflector and is perpendicular to the axis of rotation of the reflector.

[0013] Preferably, a connecting device is provided at the bottom of the drone, and the connecting device is detachably connected and matched with the reflective device, so as to facilitate the removal and assembly of the reflective device to the drone for maintenance of the reflective device.

[0014] Preferably, the UAV includes a landing gear, the height of which is greater than the height of the reflective device, so as to ensure that the reflective device does not touch the parking position when the UAV lands, thereby preventing the reflective device from being damaged.

[0015] Compared with the existing technology, the above technical solution has the following advantages: the lighting drone does not require lighting energy from ground power supply lines, which improves operation safety; and the lighting drone does not have its own lighting lamp, so the lighting does not need to rely on the power supply of the drone, which increases the lighting duration.

The vehicle 5 capable of loading the UAV 1 transports the UAV 1 to the vicinity of the operation area, controls the UAV 1 to fly above the ground where the operation is required, and then hovers in the air. The laser light on the laser emitting device 3 emits laser light into the air to the reflector 21, and the reflector 21 projects the received light downward to the ground area that needs to be illuminated. The reflective device 2 also includes a Fresnel lens, which is arranged at the bottom of the reflective device 2 through a frame 22. A sufficient gap is provided between the frame 22 and the reflector 21 to allow the laser light emitted by the laser light to pass through. The Fresnel lens is below the reflector 21, and the laser reflected by the reflector 21 is irradiated onto the Fresnel lens. After the laser light passes through the Fresnel lens, a uniform illumination area with an illumination angle of 60° is formed. Please refer to Figure 4 .

[0026] The reflective device 2 also includes an adjustment mechanism for adjusting the angle of the reflector 21. The adjustment mechanism includes a bracket 23, a first servo motor 24 with a controller fixed on the bracket 23, a first gear 25 driven by the first servo motor 24, and a second gear 26 meshed with the first gear 25 and fixedly connected to the reflector 21. The reflector 21 is rotatably connected to the bracket 23, the motor drives the first gear 25 to rotate, the first gear 25 drives the second gear 26 to rotate, thereby driving the reflector 21 fixed to the second gear 26 to rotate relative to the bracket 23, the rotation axis of the reflector 21 is horizontal, and the angle is adjusted by the horizontal rotation of the drone 1, so as to achieve multi-directional adjustment of the angle of the reflector 21 receiving the laser, so that the reflective effect of the reflector 21 is better. The second gear 26 is a half gear, and the two ends of the half gear are respectively fixed to the back of the reflector 21, and the diameter of the half gear is perpendicular to the rotation axis. The dimensional adjustment of the reflector 21 is limited to a certain range to prevent the reflector 21 from being over-adjusted and hitting the drone 1.

The drone 1 also includes a landing gear 6, and the height of the landing gear 6 is greater than the height of the reflective device 2, so as to ensure that the reflective device 2 does not touch the parking position when the drone 1 lands, thereby preventing the reflective device 2 from being damaged.

[0029] Please refer to Figure 3 On the basis of the first embodiment, the adjustment mechanism further includes a second servo motor 27 with a controller, and the second servo motor 27 drives the bracket 23 to rotate, and the axis of rotation of the bracket 23 passes through the center point of the reflector 21 and is perpendicular to the axis of rotation of the reflector 21. The reflector 21 is driven by the first servo motor 24 of the adjustment mechanism in the first embodiment to rotate along the axis of rotation by a certain angle. When the reflector 24 is in an inclined state, the second servo motor 27 of the adjustment mechanism can drive the entire bracket 23 and the reflector 21 to perform a 360° horizontal rotation, thereby changing the direction of the inclination angle of the reflector 21, so as to facilitate the reflective mirror surface of the reflector 21 to quickly align with the laser emitting device 3 located at any position on the ground, so as to quickly realize the illumination of the lighting drone.
