Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, specifically relating to a UAV high-voltage line inspection and protection device. Background Technology

[0002] In today's society, the stability and reliability of power supply are of paramount importance. As a key carrier of power transmission, the safe operation of high-voltage transmission lines is directly related to the normal operation of the entire power system. Traditional high-voltage line inspection usually adopts manual inspection, which requires inspectors to travel long distances, resulting in extremely high workload and low inspection efficiency. Therefore, drone inspection technology has emerged.

[0003] Problems with existing technology:

[0004] In high-voltage line inspection work, drones are widely used due to their flexibility and efficiency. With the camera gimbal on the drone, the appearance of the high-voltage line can be clearly photographed, and problems such as damage and deformation on the line surface can be detected in time. However, due to the complex environment of the high-voltage line, drones are easily damaged by collisions with obstacles such as tree branches during the inspection process, which affects the smooth progress of the inspection work and causes huge economic losses and safety hazards. Utility Model Content

[0005] The purpose of this invention is to provide a protection device for high-voltage line inspection by unmanned aerial vehicles (UAVs), which can deploy protective rods to protect the propellers according to the terrain being inspected, thereby reducing the damage rate and improving inspection efficiency.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A high-voltage line inspection and protection device for unmanned aerial vehicles (UAVs) includes a body. A cover plate is fixedly installed at the bottom of the body. Support rods are integrally fixedly installed at the four corners of the bottom of the cover plate. A base plate is fixedly installed at the bottom of the four support rods. A gear is rotatably arranged at the center of the top of the base plate. A spur gear is rotatably arranged at the four corners of the top of the base plate and on the periphery of the gear plate. A rotating shaft is embedded and rotatably arranged at the four corners of the top of the base plate. A spur gear is fixedly sleeved at the bottom end of each of the four rotating shafts. A bevel gear is fixedly sleeved on the outer surface of the middle of each of the four rotating shafts and on top of the spur gear. A connecting plate is fixedly sleeved at the top of each of the four rotating shafts. A rotating rod is rotatably arranged through the middle of each of the four connecting plates. A connecting rod is embedded and rotatably arranged at one end of each of the four connecting plates. A baffle is fixedly sleeved at both ends of each of the four connecting rods.

[0008] A bevel gear 2 is fixedly installed at one end of the four rotating rods and near the bevel gear, and the bevel gear 2 and bevel gear 1 are meshed together. A bevel gear 3 is fixedly installed at the other end of the four rotating rods. A bevel gear 4 is fixedly sleeved on the outer surface of the four connecting rods and near the bevel gear 3, and the bevel gear 4 and bevel gear 3 are meshed together.

[0009] A support plate is integrally fixed at the center of each of the four sides of the bottom of the cover plate, and the top of the cover plate, the bottom plate and the gear plate are all provided with equally spaced through slots.

[0010] A micro motor is embedded and fixedly installed at the center of the top of the cover plate, and paddle rods are rotatably installed at the four corners of the body. The length of the connecting plate is longer than the length of the paddle rods.

[0011] The technical effects achieved by this utility model are as follows:

[0012] In this invention, when a drone encounters complex terrain during inspection, a micro motor drives a gear disk to rotate, which in turn rotates a first spur gear meshing with it, which in turn drives a second spur gear to rotate. This, in turn, causes a rotating rod to rotate via a first bevel gear and a second bevel gear meshing with it. Furthermore, a third bevel gear and a fourth bevel gear cause a baffle to be perpendicular to the propeller shaft, protecting the propeller blades around the shaft from damage caused by obstacles, reducing the damage rate, improving inspection efficiency, and minimizing losses. Simultaneously, when the terrain is relatively open, the micro motor rotates in the opposite direction to store the connecting plate and baffle on the side of the cover plate and base plate, thereby reducing flight resistance and energy consumption.

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe a UAV high-voltage line inspection and protection device or several specific implementation methods of this utility model, and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figures 1-5 As shown, a high-voltage line inspection and protection device for unmanned aerial vehicles (UAVs) includes a body 1. A cover plate 2 is fixedly installed at the bottom of the body 1. Support rods 10 are integrally fixedly installed at the four corners of the bottom of the cover plate 2. A base plate 5 is fixedly installed at the bottom of the four support rods 10. A gear 8 is rotatably installed at the center of the top of the base plate 5. A spur gear 9 is rotatably installed at the four corners of the top of the base plate 5 and around the gear 8. A rotating shaft 13 is embedded and rotatably installed at the four corners of the top of the base plate 5. A spur gear 12 is fixedly sleeved at the bottom end of each of the four rotating shafts 13. A bevel gear 15 is fixedly sleeved on the outer surface of the middle of each of the four rotating shafts 13 and on top of the spur gear 12. A connecting plate 11 is fixedly sleeved at the top of each of the four rotating shafts 13. A rotating rod 17 is rotatably installed through the middle of each of the four connecting plates 11. A connecting rod 20 is embedded and rotatably installed at one end of each of the four connecting plates 11. A baffle 21 is fixedly sleeved at both ends of each of the four connecting rods 20.

[0022] See attached document Figure 4 A bevel gear 16 is fixedly installed at one end of the four rotating rods 17 and near the bevel gear 15. The bevel gear 16 and the bevel gear 15 are meshed together. A bevel gear 18 is fixedly installed at the other end of the four rotating rods 17. A bevel gear 19 is fixedly sleeved on the outer surface of the four connecting rods 20 and near the bevel gear 18. The bevel gear 19 and the bevel gear 18 are meshed together.

[0023] According to the above structure, when the UAV encounters complex terrain during inspection operations, the micro motor 7 drives the gear disk 8 to rotate, which in turn drives the four spur gears 9 around the gear disk 8 to rotate, which in turn drives the four spur gears 12 to rotate, causing the connecting plate 11 to rotate. When the spur gears 12 rotate, they drive the connecting rod 20 to rotate through the rotating shaft 13, bevel gear 15, rotating rod 17, bevel gear 18, and bevel gear 19. The rotation of the connecting rod 20 causes the two baffles 21 to rotate from bottom to top, so that the baffles 21 are perpendicular to the periphery of the propeller blade at one end of the propeller rod 3, protecting the propeller blade and preventing obstacles from damaging it, reducing the damage rate and improving inspection efficiency. The surface of the baffles 21 is equipped with collision sensors, which can provide early warning of collisions. The baffles 21 are made of elastic material, which can absorb a certain amount of impact force when a collision occurs, preventing the UAV from becoming unbalanced due to the direct impact force.

[0024] See attached document Figure 2 and Figure 3 Support plates 6 are integrally fixedly installed at the center of the four sides of the bottom of the cover plate 2. Holes 4 are equally spaced through the top of the cover plate 2, the bottom plate 5 and the gear plate 8. A micro motor 7 is embedded and fixedly installed at the center of the top of the cover plate 2. Paddle rods 3 are rotatably installed at the four corners of the body 1. The length of the connecting plate 11 is longer than the length of the paddle rod 3.

[0025] According to the above structure, all materials are made of lightweight materials to reduce the weight of the fuselage 1 during flight and avoid excessive energy consumption due to excessive weight. The cover plate 2, the bottom plate 5 and the top of the gear plate 8 are all equidistantly through-holes 4 to further reduce the drag of the fuselage 1 during flight. The support plate 6 can support the connecting plate 11 when it is retracted, thereby improving the stability of the connecting plate 11. The length of the connecting plate 11 is longer than the length of the propeller 3 and longer than the length of the propeller 3 plus the outer diameter of the propeller blade, thereby protecting the periphery of the propeller blade.

[0026] The working principle of this utility model is as follows: When the UAV encounters complex terrain during inspection operations, the micro motor 7 drives the gear disk 8 to rotate, which in turn drives the four spur gears 9 on the periphery of the gear disk 8 to rotate, which in turn drives the four spur gears 12 to rotate, causing the connecting plate 11 to rotate. When the spur gears 12 rotate, the connecting rod 20 rotates through the rotating shaft 13, bevel gear 15, rotating rod 17, bevel gear 18, and bevel gear 19. The rotation of the connecting rod 20 causes the two baffles 21 to rotate from bottom to top, so that the baffles 21 are perpendicular to the periphery of the propeller blade at one end of the propeller rod 3, protecting the propeller blade and preventing obstacles from damaging the propeller blade, reducing the damage rate, and improving inspection efficiency. The surface of the baffles 21 is equipped with collision sensors, which can provide early warning of collisions. The baffles 21 are made of elastic material, which can absorb a certain amount of impact force when a collision occurs, preventing the direct impact force from causing the UAV to lose balance.

[0027] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
