Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle lighting, and in particular to a lighting device and method for an unmanned aerial vehicle used for power maintenance. Background Art

[0002] Nighttime inspections of power lines mainly rely on manpower, with inspectors using handheld lights to illuminate and telescopes to observe. Instantaneous faults such as lightning strikes and foreign objects often cause fault points to be located at high places, which are hidden and difficult to identify. In addition, there are risks of falling and electric shock when climbing at night, which is very inefficient and poses safety hazards, resulting in extended inspection time and failure to quickly restore power supply. In response to the above problems, the commonly used method is to use drone lighting to assist in inspections.

[0003] However, through the analysis of traditional UAV lighting, it can be found that due to the low light at night, the safety of the UAV flight environment cannot be guaranteed, and it is difficult to meet the needs of high-precision inspections. At present, some UAVs have mounted lighting equipment, or infrared cameras and other equipment are needed for night photography. These devices are expensive and have certain limitations; and the existing UAV lighting systems often simply mount one or more wired tethered lamps, such as the UAV lighting lamps provided by the patent with publication number CN114148537A, which lack automatic control and adjustment; more importantly, some existing UAV lighting devices are simply installed between the UAV and the UAV, lacking effective protection for the lighting devices.

[0004] Therefore, in view of the above-mentioned problems, the present technical solution proposes a lighting device and method for a UAV for power maintenance. Summary of the invention

[0005] The object of the present invention is to provide a lighting device and method for an unmanned aerial vehicle for power maintenance to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a lighting device for a UAV for power maintenance, comprising a UAV body, four sets of rotors are connected to the outer wall of the UAV body through four sets of brackets evenly distributed obliquely upward, and a transmission structure is arranged inside the bracket to maintain the transmission connection between the rotor and the UAV body, that is, to maintain the normal control flight between the UAV body and the rotor;

[0007] Two sets of landing gears are detachably installed on both sides of the bottom of the drone body. The landing gears are used to support the drone body for stable and safe landing. The landing gears include a set of connecting diagonal rods and supporting bottom rods fixed at the bottom of the connecting diagonal rods and vertically distributed therewith. The top of the connecting diagonal rods is detachably connected to the bottom of the drone body. When the landing gear supports the drone body for landing, the contact support between the bottom of the supporting bottom rods and the ground and the inclined connection of the connecting diagonal rods can effectively provide stable support for the drone body.

[0008] A group of side position lights are disassembled and lifted in the middle of the connecting diagonal rod. The lighting directions of the side position lights on the connecting diagonal rods on both sides are set in opposite directions. By adjusting the height of the side position lights, multi-directional lighting can be performed when the power is inspected and repaired. A lighting opening is opened on the bottom wall of the supporting bottom rod. A group of auxiliary searchlights are rotatably arranged inside the supporting bottom rod. The light of the auxiliary searchlights is emitted outward through the lighting opening. At the same time, with the swing of the auxiliary searchlights, the areas on both sides of the bottom of the supporting bottom rod are inspected and illuminated within a certain range. The side position lights and the auxiliary searchlights are connected to a group of adjustable power components. The adjustable power components are arranged on the supporting bottom rod and the connecting diagonal rod. The height of the side position lights and the swing angle of the auxiliary searchlights can be adjusted at the same time through the adjustable power components, that is, automatic lighting adjustment is realized, and the conversion and utilization rate of kinetic energy is increased to a certain extent.

[0009] A set of main searchlight boxes are detachably installed at the bottom of the UAV body. An automatic entrance and exit of the main searchlight is opened at the bottom of the main searchlight box. Two sets of baffles are set on both sides of the automatic entrance and exit of the main searchlight. The tops of the baffles on both sides are connected with an opening and closing component. The opening and closing component is used to control the relative movement of the baffles on both sides (that is, to control the opening and closing of the automatic entrance and exit of the main searchlight). At the same time, a set of main searchlights are lifted inside the main searchlight box. The main searchlight is used to illuminate the main range during power maintenance. The main searchlight is connected to a horizontal and vertical swing mechanism box toward the inside of the main searchlight box. A moving component is connected to the side of the horizontal and vertical swing mechanism box toward the opening and closing component. The moving component is used to control the horizontal and vertical swing mechanism box to move along the main searchlight automatically. The movable entrance and exit enter and exit the main searchlight box, and the opening and closing components and the moving components are connected together with a group of driving mechanisms arranged inside the main searchlight box; when the driving mechanism operates to control the opening and closing components to open the automatic entrance and exit of the main searchlight, it drives the moving components to control the horizontal and vertical swinging mechanism box to move outward along the automatic entrance and exit of the main searchlight. On the contrary, when the driving mechanism controls the opening and closing components to close the automatic entrance and exit of the main searchlight, it drives the moving components to control the horizontal and vertical swinging mechanism box to be stored in the main searchlight box along the automatic entrance and exit of the main searchlight, thereby realizing the automatic mobile lighting use of the main searchlight and the operation process of storage, return and preservation. This process is automated and can effectively improve the protection of the main searchlight.

[0010] Based on a lighting device for a drone used for power maintenance, the method of use is as follows:

[0011] Step 1, installation: Turn the mounting bolt to thread it into the inner screw hole at the bottom of the drone body, then turn the locking nut to fix it, and then control the embedded rod at the top of the connecting diagonal rod to be embedded in the embedded groove at the bottom of the drone body, so as to fix the landing gear on both sides of the bottom of the drone body, and fix the side position light on the connecting diagonal rod through the clamping of the bayonet pin and the slot block. At this time, the main searchlight, side position light, and auxiliary searchlight are all in a state of waiting for use under the drone body;

[0012] Step 2, lighting start: For the main searchlight, start the servo motor II to control the gear rod to rotate, and then drive the driving gear II to rotate under the transmission of the bevel gear III, bevel gear IV and the connecting shaft, and then control the two sets of top racks meshing with it to slide relative to each other, so as to control the two sets of gates to separate relative to each other, and open the main searchlight automatic inlet and outlet. At the same time, under the transmission of the transmission belt, control the toggle gear to rotate, and then control the inlet and outlet racks to move outward, and then synchronously control the horizontal and vertical swing mechanism box to move outward along the main searchlight automatic inlet and outlet, and move the main searchlight on it to the outside of the main searchlight box to wait for use, and synchronously adjust the extension position of the main searchlight;

[0013] For the side position lights and auxiliary searchlights, the servo motor I is started to drive the driving gear I to rotate, and then the gear ring meshing with it is controlled to rotate, so as to control the rotation of the auxiliary searchlight, and the swing angle of its bottom is adjusted to make its irradiation surface face the lighting opening, and the bevel gear II is controlled to mesh with the bevel gear I by starting the electric telescopic rod, and then the lead screw is controlled to rotate to adjust the height of the side position lights. At this time, the main searchlight, side position lights, and auxiliary searchlights are all in the on state;

[0014] Step 3, lighting azimuth angle adjustment: for the main searchlight, the lateral servo motor is controlled to operate and adjust the swing angle of the mounting sleeve, and then the longitudinal angle of the main searchlight is adjusted under the connection of the swing connecting rod, U-shaped mounting plate and other structures, and the longitudinal servo motor is started to control the rotation of the main rotating disk, and then the lateral angle of the main searchlight is adjusted under the connection of the wheel belt and other structures, so as to adjust the multi-angle of the main searchlight during the power maintenance;

[0015] For the side position lights, the nut is driven to move along the lead screw by controlling the rotation of the lead screw to adjust its height, and the side position lights on both sides are used to illuminate the two sides. For the auxiliary searchlight, the gear ring is driven to rotate by controlling the driving gear I to adjust its angle and make fine adjustments to its illumination angle.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] By making detachable connections between the main searchlight box, landing gear and UAV body, it is convenient for quick installation and removal between the UAV body, and is conducive to the replacement and maintenance of various structural components; by arranging height-adjustable side position lights and angle-adjustable auxiliary searchlights on the landing gear, a certain range of adaptive lighting can be performed according to the azimuth lighting needs of power maintenance, and at the same time it has a certain energy-saving effect.

A transmission structure is arranged inside the bracket 11 to maintain the transmission connection between the rotors 12 and the unmanned aerial vehicle body 10, that is, to maintain the normal control flight between the unmanned aerial vehicle body 10 and the rotors 12;

[0037] Two sets of landing gears 16 are detachably installed on both sides of the bottom of the drone body 10. The landing gears 16 are used to support the drone body 10 to land stably and safely. The landing gears 16 include a set of connecting diagonal rods 18 and supporting bottom rods 17 fixed at the bottom of the connecting diagonal rods 18 and vertically distributed therewith. The top of the connecting diagonal rods 18 is detachably connected to the bottom of the drone body 10. When the landing gears 16 support the drone body 10 for landing, the drone body 10 can be effectively stably supported by the contact support between the bottom of the supporting bottom rods 17 and the ground and the inclined connection of the connecting diagonal rods 18.

[0038] A group of side position lights 20 are disassembled and lifted in the middle of the connecting oblique rod 18.

The side position lights 20 and the auxiliary searchlights 21 are connected together with a group of adjustable power components. The adjustable power components are arranged on the supporting bottom rod 17 and the connecting oblique rod 18. The height of the side position lights 20 and the swing angle of the auxiliary searchlights 21 can be adjusted at the same time by the adjustable power components, that is, automatic lighting adjustment is realized, and the conversion and utilization rate of kinetic energy is increased to a certain extent.
