Description

Technical Field

[0001] This invention relates to the field of inspection equipment technology, specifically to an inspection drone for power maintenance. Background Technology

[0002] Power grid maintenance and inspection play a crucial role in the normal operation of the main power grid. For a long time, power grid maintenance and inspection have relied on manual methods, which are labor-intensive, difficult, and sometimes endanger the lives of inspection personnel. With the development of machine vision and drone technology, drones, through visual recognition cameras, can now perform intelligent maintenance and inspection of power lines and towers, resulting in a significant increase in efficiency compared to manual inspections.

[0003] Damage to the lens on a drone will affect its shooting. In addition, drones are prone to malfunctions during use. Mechanical failures can cause the drone to fall directly, resulting in significant economic losses. Furthermore, drones are also prone to damaging objects on the ground. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a patrol drone for power maintenance, comprising a drone body, a frame fixedly installed on the outside of the drone body, a propeller rotatably connected to the top of the frame, and a protective net fixedly connected to the top of the frame, the protective net being located outside the propeller; The camera, used for real-time shooting, is fixedly mounted on the drone body. The drone body includes an upper shell, a connector fixedly connected to the bottom of the upper shell, and a base fixedly connected to the bottom of the connector. The base is fixedly connected to the upper shell via the connector. A slot is formed on the outer side of the connector, and the camera is located inside the slot. A protective component is snapped onto the outer side of the connector near the camera. When the drone is not in use, the cover plate slides and adapts to the connector. The camera lens is located inside the cylinder, and a limiting plate is located inside the through hole. Utilizing the elasticity of the limiting plate, the cover plate snaps onto the upper shell and the connector, thereby protecting the drone lens and preventing wear and dust accumulation that may occur when the lens is not in use. During use, the user can apply pressure to the limiting plate. The force applied causes the limiting plate to compress the contact between the cylinders. At this point, pulling the cover plate outward allows it to be removed, exposing the lens and facilitating the drone's shooting needs. The connector has two through holes on its outer side near the camera, symmetrically arranged around the camera. Each through hole contains a cylinder with magnetic properties, with the upper and lower symmetrical cylinders having opposite magnetic properties. The cover plate is located inside the slot, and the mutual attraction between the upper and lower symmetrical cylinders limits and fixes the limiting plate, preventing it from detaching from the connector after the elasticity fails. The cylinders are symmetrically arranged around the connector, slidably connected to the upper shell, and slidably connected to the base. The protective assembly includes a cover plate with a cylinder at one end near the camera. The cylinder slides and adapts to the camera. A limiting plate, which is V-shaped, is fixedly connected to the outer side of the cover plate near the through hole and is located inside the through hole. The limiting plate engages with the through hole.

[0005] Preferably, a buffer component is provided at the bottom center of the base, a bracket is slidably connected to the bottom edge of the base, an elastic rope is fixedly connected to the outside of the bracket, and there are multiple brackets connected by elastic ropes.

[0006] The base includes a lower housing, which is fixedly connected to the bottom of the connector. An annular groove is formed at the bottom edge of the lower housing. A limiting groove is formed at the bottom of the lower housing. There are multiple limiting grooves, which are evenly distributed around the buffer component. A sliding groove is formed inside the limiting groove. A fixing frame is fixedly connected to the bottom of the lower housing. The fixing frame is located on the side of the limiting groove close to the annular groove. A circular groove is formed at the bottom of the lower housing, which is located between the annular groove and the limiting groove.

[0007] Preferably, the buffer assembly includes a round rod slidably connected to the lower housing, the round rod penetrating the lower housing, and a round plate fixedly connected to the outer side of the round rod. The round plate is located inside the lower housing and slidably connected to the lower housing. After the drone finishes its operation, it descends, causing the bottom of the mounting base to contact the ground. The mounting base moves the round rod upward, causing the round plate to exert a force on the return spring. Utilizing the elasticity of the return spring, a buffering effect is achieved, thus preventing the drone from colliding with the ground and potentially damaging the drone itself. The effect is good and the practicality is strong. When moving upwards, the support plate moves upwards along with the fixed seat, causing the support plate to move away from the round rod inside the limiting groove. This creates pressure between the support plate and the fixed plate, causing the rotating rod to move away from the round rod in the sliding groove. At the same time, the compression spring is compressed, and the fixed block unfolds outwards, thus supporting the drone. The end of the round rod away from the lower shell is fixedly connected to the fixed seat, and the support plate is rotatably connected to the outside of the fixed seat. The end of the support plate away from the fixed seat is slidably connected to the limiting groove. A return spring is fixedly connected to the side of the round plate away from the fixed seat, and the end of the return spring away from the round plate is fixedly connected to the connecting piece.

[0008] Preferably, the bracket includes a rotating rod located inside a sliding groove. The rotating rod is slidably connected to the sliding groove, and a fixed plate is rotatably connected to the outer side of the rotating rod. When the drone is working, the propeller rotates, thereby driving the drone body to move upward. Under the elastic force of the return spring, the fixed seat moves away from the connecting piece, causing the fixed seat to drive the support plate to move towards the round rod. At this time, under the elastic force of the compression spring, the rotating rod moves towards the round rod inside the sliding groove. Simultaneously, the outer side of the fixed plate is squeezed against the fixed frame, causing the elastic rope to be stretched, thereby causing the fixed plate to rotate around the rotating rod. At this time, the fixed plate is located inside the limiting groove, and the fixed block is located inside the annular groove, so that during operation, the fixed block automatically... To prevent the drone from contacting or getting stuck with tree branches during flight, the fixing plate has a groove on its outer side. The elastic rope is located inside the groove. A fixing rod is fixedly connected to the end of the fixing plate away from the rotating rod. A fixing block is fixedly connected to the end of the fixing rod away from the fixing plate. Utilizing the elasticity of the elastic rope, the fixing plate moves away from the round rod, causing it to rotate around the rotating rod. At this time, the drone is supported by multiple fixing blocks. The fixing blocks are arc-shaped and located inside the annular groove. The fixing rod is located inside the circular groove. A compression spring is fixedly connected to the side of the rotating rod near the fixing rod. The end of the compression spring away from the rotating rod is fixedly connected to the inner wall of the limiting groove.

[0009] Preferably, the frame includes support rods, which are fixedly connected to the outer side of a connector. There are multiple support rods evenly distributed around the connector. The end of each support rod furthest from the connector is rotatably connected to a propeller. Each support rod is fixedly connected to a protective net, and the propeller is located inside the protective net. The protective net prevents the propeller from being entangled by ropes, threads, branches, weeds, or other objects, which could hinder propeller rotation, disrupt the drone's dynamic balance, and affect flight stability and controllability. A connecting plate is fixedly connected to the outer side of each support rod, and both ends of the connecting plate are fixedly connected to two adjacent support rods. A connecting rod is slidably connected to the outer side. A positioning plate is fixedly connected to the end of the connecting rod near the support rod. When the drone experiences a minor collision, the baffle is forced to slide the connecting rod against the connecting plate. At this time, the limit spring is compressed and deformed, which plays a buffering role, thereby effectively protecting the drone's key components, such as motors, sensors, and circuit boards, reducing damage caused by collisions, dust, rain, etc., thereby reducing the failure rate and extending the drone's service life. A baffle is fixedly connected to the end of the connecting rod away from the positioning plate. A limit spring is fixedly connected to the end of the baffle near the connecting plate, and the end of the limit spring away from the baffle is fixedly connected to the connecting plate.

[0010] This invention provides a patrol drone for power line maintenance. It has the following advantages: I. This inspection drone for power maintenance utilizes the elasticity of a limiting plate to engage the cover plate with the upper housing and connectors, thereby protecting the drone's lens and preventing wear and dust accumulation when the lens is not in use. When in use, the user can apply force to the limiting plate, causing it to press against the cylinders. By pulling the cover plate outward, it can be removed, exposing the lens and facilitating the drone's shooting needs.

[0011] Second, this inspection drone used for power maintenance applies force to the return spring through a circular plate. Utilizing the elasticity of the return spring, it acts as a buffer, thereby preventing the drone from colliding with the ground and potentially damaging the drone itself. The effect is good and the practicality is strong.

[0012] Third, the inspection drone used for power maintenance creates pressure between the outer side of the fixed plate and the fixed frame, causing the elastic rope to stretch and the fixed plate to rotate around the rotating rod. At this time, the fixed plate is located inside the limiting groove and the fixed block is located inside the annular groove, so that the fixed block is automatically retracted during operation, avoiding contact with tree branches and objects during flight and preventing them from getting stuck.

[0013] Fourth, this patrol drone used for power maintenance uses a baffle to drive the connecting rod to slide on the connecting plate. At this time, the limit spring is compressed and deformed, which plays a buffering role, thereby effectively protecting the key components of the drone, such as motors, sensors, and circuit boards, reducing damage caused by collisions, dust, rain, etc., thereby reducing the failure rate and extending the service life of the drone.

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0017] First embodiment, such as Figures 1 to 6 As shown, the present invention provides a technical solution: a patrol drone for power maintenance, including a drone body 1, a frame 2 fixedly installed on the outside of the drone body 1, a propeller 3 rotatably connected to the top of the frame 2, and a protective net 5 fixedly connected to the top of the frame 2, the protective net 5 being located outside the propeller 3. Camera 4, used for real-time shooting, is fixedly mounted on the drone body 1. The drone body 1 includes an upper shell 11, with a connector 16 fixedly connected to the bottom of the upper shell 11. A base 13 is fixedly connected to the bottom of the connector 16, and the base 13 is fixedly connected to the upper shell 11 via the connector 16. A slot is provided on the outer side of the connector 16, and a camera 4 is located inside the slot. A protective component 12 is snapped onto the outer side of the connector 16 near the camera 4. When the drone is not in use, the cover plate 121 slides and adapts to the connector 16, with the camera lens located inside the cylinder 122. A limiting plate 123 is located inside the through hole 14. Utilizing the elasticity of the limiting plate 123, the cover plate 121 snaps onto the upper shell 11 and the connector 16, thereby protecting the position of the drone lens and preventing wear and dust accumulation that may occur when the lens is not in use. When in use, the user can apply force to the limiting plate 123. The limiting plate 123 then presses against the cylinder 15, allowing the cover plate 121 to be pulled outwards, thus exposing the lens and facilitating the drone's shooting needs. The connector 16 has two through holes 14 on its outer side near the camera 4, symmetrically arranged around the camera 4. A cylinder 15 is installed inside the through hole 14, which is magnetic. The symmetrically arranged cylinders 15 have opposite magnetic properties. The cover plate 121 is located inside the slot, and the mutual attraction between the symmetrically arranged cylinders 15 limits and fixes the limiting plate 123, preventing the cover plate 121 from detaching from the connector 16 after the elasticity fails. The cylinders 15 are symmetrically arranged around the connector 16, and are slidably connected to the upper shell 11 and the base 13. The protective component 12 includes a cover plate 121. A cylinder 122 is provided at one end of the cover plate 121 near the camera 4. The cylinder 122 is slidably fitted to the camera 4. A limiting plate 123 is fixedly connected to the outer side of the cover plate 121 near the through hole 14. The limiting plate 123 is V-shaped and located inside the through hole 14. The limiting plate 123 engages with the through hole 14.

[0018] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 7 to 10 As shown, a buffer assembly 17 is provided at the bottom center of the base 13, and a bracket 18 is slidably connected to the bottom edge of the base 13. An elastic rope 19 is fixedly connected to the outside of the bracket 18. There are multiple brackets 18, and multiple brackets 18 are connected by elastic ropes 19.

[0019] The base 13 includes a lower housing 131, which is fixedly connected to the bottom of the connector 16. An annular groove 132 is provided at the bottom edge of the lower housing 131. A limiting groove 133 is provided at the bottom of the lower housing 131. There are multiple limiting grooves 133, which are evenly distributed around the buffer component 17. A sliding groove 134 is provided inside the limiting groove 133. A fixing frame 135 is fixedly connected to the bottom of the lower housing 131. The fixing frame 135 is located on the side of the limiting groove 133 near the annular groove 132. A circular groove 136 is provided at the bottom of the lower housing 131, which is located between the annular groove 132 and the limiting groove 133.

[0020] The buffer assembly 17 includes a round rod 171, which is slidably connected to the lower housing 131 and passes through the lower housing 131. A round plate 174 is fixedly connected to the outer side of the round rod 171 and is located inside the lower housing 131. The round plate 174 is slidably connected to the lower housing 131. After the drone finishes its operation, it descends, causing the bottom of the fixed base 172 to contact the ground. The fixed base 172 drives the round rod 171 to move upward, thereby causing the round plate 174 to apply force to the return spring 175. Utilizing the elastic properties of the return spring 175, a buffering effect is achieved, thus preventing the drone from colliding with the ground and potentially damaging the drone itself. The effect is good and the practicality is strong. When the fixed base 172 moves upward, the support plate 173 moves accordingly. As the fixed seat 172 moves upward, the support plate 173 moves away from the round rod 171 inside the limiting groove 133, thereby creating pressure between the support plate 173 and the fixed plate 182. This causes the rotating rod 181 to move away from the round rod 171 in the sliding groove 134. At the same time, the compression spring 186 is compressed, and the fixed block 185 unfolds outward, thus providing support for the drone. The end of the round rod 171 away from the lower housing 131 is fixedly connected to the fixed seat 172. The support plate 173 is rotatably connected to the outside of the fixed seat 172. The end of the support plate 173 away from the fixed seat 172 is slidably connected to the limiting groove 133. The side of the round plate 174 away from the fixed seat 172 is fixedly connected to the return spring 175. The end of the return spring 175 away from the round plate 174 is fixedly connected to the connector 16.

[0021] The bracket 18 includes a rotating rod 181, which is located inside the slide groove 134 and slidably connected to the slide groove 134. A fixing plate 182 is rotatably connected to the outer side of the rotating rod 181. When the drone is working, the propeller 3 rotates, thereby driving the drone body 1 to move upward. The fixing seat 172 moves away from the connector 16 under the elastic force of the return spring 175, causing the fixing seat 172 to drive the support plate 173 to move towards the round rod 171. At this time, under the elastic force of the compression spring 186, the rotating rod 181 moves towards the round rod 171 inside the slide groove 134. At the same time, the outer side of the fixing plate 182 is squeezed against the fixing frame 135, causing the elastic rope 19 to be stretched. Thus, the fixing plate 182 rotates around the rotating rod 181. At this time, the fixing plate 182 is located inside the limiting groove 133, and the fixing block 185 is located inside the annular groove 132, so that during operation, the fixing block... The drone is automatically recovered to prevent it from contacting or getting stuck with tree branches or other objects during flight. A groove 183 is provided on the outer side of the fixing plate 182, and an elastic rope 19 is located inside the groove 183. A fixing rod 184 is fixedly connected to the end of the fixing plate 182 away from the rotating rod 181, and a fixing block 185 is fixedly connected to the end of the fixing rod 184 away from the fixing plate 182. When the fixing plate 182 moves away from the round rod 171 using the elastic properties of the elastic rope 19, it rotates around the rotating rod 181. At this time, the drone is supported by multiple fixing blocks 185. The fixing blocks 185 are arc-shaped and located inside the annular groove 132. The fixing rod 184 is located inside the round groove 136. A compression spring 186 is fixedly connected to the side of the rotating rod 181 near the fixing rod 184. The end of the compression spring 186 away from the rotating rod 181 is fixedly connected to the inner wall of the limiting groove 133.

[0022] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figure 11As shown, the frame 2 includes support rods 21, which are fixedly connected to the outer side of the connector 16. There are multiple support rods 21, evenly distributed around the connector 16. The end of each support rod 21 furthest from the connector 16 is rotatably connected to the propeller 3. The support rods 21 are also fixedly connected to a protective net 5. The propeller 3 is located inside the protective net 5. The protective net 5 prevents the propeller 3 from being entangled by ropes, threads, branches, weeds, or other objects, which could hinder its rotation, disrupt the drone's dynamic balance, and affect flight stability and controllability. A connecting plate 22 is fixedly connected to the outer side of each support rod 21. Both ends of the connecting plate 22 are fixedly connected to two adjacent support rods 21. The outer side of the connecting plate 22 is slidably connected... A connecting rod 23 is connected to a positioning plate 24 at one end of the connecting rod 23 near the support rod 21. When the drone experiences a minor collision, the baffle 26 is forced to slide the connecting rod on the connecting plate 22. At this time, the limiting spring 25 is compressed and deformed, which plays a buffering role, thereby effectively protecting the drone's key components, such as motors, sensors, and circuit boards, reducing damage caused by collisions, dust, rain, etc., thereby reducing the failure rate and extending the drone's service life. The baffle 26 is fixedly connected to the end of the connecting rod 23 away from the positioning plate 24. The limiting spring 25 is fixedly connected to the end of the baffle 26 near the connecting plate 22, and the end of the limiting spring 25 away from the baffle 26 is fixedly connected to the connecting plate 22.

[0023] When in use, the user can apply force to the limiting plate 123, which will cause the limiting plate 123 to press against the cylinder 15. At this time, the cover plate 121 can be pulled outward to remove the cover plate 121, thereby exposing the lens and facilitating the shooting needs of the drone.

[0024] When the drone is in operation, the propeller 3 rotates, thereby driving the drone body 1 to move upward. Under the elastic force of the return spring 175, the fixed base 172 moves away from the connector 16, causing the fixed base 172 to drive the support plate 173 to move towards the round rod 171. At this time, under the elastic force of the compression spring 186, the rotating rod 181 moves towards the round rod 171 inside the slide groove 134. At the same time, the outer side of the fixed plate 182 is squeezed between the fixed frame 135, causing the elastic rope 19 to be stretched. Thus, the fixed plate 182 rotates around the rotating rod 181. At this time, the fixed plate 182 is located inside the limiting groove 133, and the fixed block 185 is located inside the annular groove 132, so that the fixed block 185 automatically retracts during operation, avoiding contact with tree branches and objects during flight and preventing jamming.

[0025] When the drone experiences a minor collision, the baffle 26 is forced to slide the connecting rod on the connecting plate 22. At this time, the limit spring 25 is compressed and deformed, which acts as a buffer, thereby effectively protecting the drone's key components, such as motors, sensors, and circuit boards, reducing damage caused by collisions, dust, rain, etc., thus reducing the failure rate and extending the drone's service life.

[0026] After the drone finishes its work, it descends, causing the bottom of the mounting base 172 to contact the ground. The mounting base 172 drives the round rod 171 to move upward, thereby causing the round plate 174 to apply force to the return spring 175. The elasticity of the return spring 175 acts as a buffer, preventing the drone from colliding with the ground and causing potential damage. This method is effective and practical. As the mounting base 172 moves upward, the support plate 173 also moves upward, causing it to move away from the round rod 171 within the limiting groove 133. This creates pressure between the support plate 173 and the mounting plate 182, causing the rotating rod 181 to move away from the round rod 171 within the sliding groove 134. Simultaneously, the compression spring 186 is compressed, causing the mounting block 185 to unfold outward, thus supporting the drone.

[0027] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
