Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a power line inspection UAV with obstacle avoidance capabilities. Background Technology

[0002] With the rapid development of technology, drone technology is gradually changing the face of various industries, with its application in the field of power line inspection being particularly noteworthy. Drones, with their unique flight capabilities and efficient operating methods, have brought about a revolutionary change to power line inspection.

[0003] The inspection of high-voltage transmission lines is a crucial part of power facility maintenance. Traditional manual inspections are inefficient and risky. While existing drone inspection technology can partially replace manual inspections, it still suffers from insufficient mobility under variable airflow conditions. In unstable airflow conditions, the protection of the detection device is inadequate, which can easily lead to inspection difficulties. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this application is to provide a power line inspection drone with obstacle avoidance capabilities. This drone avoids the problems of insufficient maneuverability and unstable camera devices caused by varying airflow, which lead to inspection difficulties. It solves the problems of insufficient maneuverability under varying airflow conditions and poor protection of the inspection device under unstable airflow conditions, which easily leads to inspection difficulties.

[0005] The power inspection drone with obstacle avoidance function provided in this application adopts the following technical solution: it includes a drone body, and the outer surface of the drone body is provided with wings;

[0006] The drone body has a balance frame rotatably connected to both sides. The bottom of the drone body is provided with a limit component. The limit component has a drive mechanism inside. The output end of the drive mechanism is threadedly connected to a suspension mechanism. The inner wall of the suspension mechanism is rotatably connected to a camera device. One end of the suspension mechanism is fixedly connected to an electric push device. The electric push device is slidably connected to the outside of the limit component. An elastic protective mechanism is fixedly installed inside the suspension mechanism.

[0007] By adopting the above technical solution, and connecting the electric push device to the suspension mechanism, when the UAV encounters unstable airflow during power inspection, the drive mechanism is activated to drive the suspension mechanism to move longitudinally along the lower part of the limiting component, causing the camera device to move inward together. At the same time, the electric push device moves inward together and, after activation, generates a pushing force on the camera device, pushing it to flip upward and push the elastic protective mechanism upward and then reset it. The flipped camera device is then covered inside the suspension mechanism to provide protection and prevent the UAV from becoming less maneuverable and the camera device from becoming unstable and causing inspection difficulties when encountering variable airflow.

[0008] Preferably, the limiting component includes a limiting base, the limiting base has an inner groove, and both sides of the limiting base have limiting grooves. The electric pushing device is slidably connected to the inner wall of the limiting groove.

[0009] By adopting the above technical solution, an inner groove is opened inside the limiting base to provide built-in space for the drive mechanism, while limiting the displacement path of the suspension mechanism and the electric pushing device to avoid displacement instability.

[0010] Preferably, the drive mechanism includes a drive motor, the output end of which is fixedly mounted with a threaded shaft, the threaded shaft passing through the interior of the inner groove and threadedly connected to the suspension mechanism.

[0011] By adopting the above technical solution, through the cooperation of the drive motor and the threaded shaft, when the drive motor is started, the threaded shaft rotates inside the inner groove to drive the suspension mechanism to move longitudinally along the bottom of the limiting base, thereby causing the camera device to retract, reducing the airflow through the space and avoiding adverse damage to the camera device.

[0012] Preferably, the suspension mechanism includes a suspension body, a limit slider is fixedly installed on the top of the suspension body, the limit slider is threadedly connected to the threaded shaft, a suspension frame is fixedly installed on the bottom of the suspension body, and the camera device is rotatably installed inside the suspension frame.

[0013] By adopting the above technical solution, the limiting slider is extended into the inner groove, and the limiting slider is driven to slide by the drive motor and the threaded shaft, so as to provide displacement driving force for the suspension body and the suspension frame. When stationary, the suspension body can provide stable suspension support for the camera device.

[0014] Preferably, the camera device includes a camera, the outer surface of which is provided with a top plate, the top plates being symmetrically arranged outside the camera, and the camera being located inside the suspension frame.

[0015] By adopting the above technical solution, the camera housing is rotatably connected to the inside of the suspension frame, so that the camera has a flexible detection angle, and when the electric push device pushes it to flip, it can flip upward to the inside of the suspension frame to achieve the effect of inward protection.

[0016] Preferably, the electric pushing device includes an electric pushing motor, a sliding block is fixedly installed on the top of the electric pushing motor, an electric push rod is provided at the output end of the electric pushing motor, a connecting push plate is rotatably connected to one end of the camera, and one end of the connecting push plate is rotatably connected to the output end of the electric push rod.

[0017] By adopting the above technical solution, the electric pusher is activated to drive the electric push rod to extend and retract downwards, thereby generating a pushing force on the connecting push plate. While the connecting push plate gradually flips and shifts downwards, it generates a unidirectional traction force on the camera, so that when the camera flips, its own push elastic protection mechanism retracts inwards, thus providing a driving force for the camera to flip and retract.

[0018] Preferably, the elastic protective mechanism includes an elastic protective cover, and a plurality of springs are fixedly installed on the top of the elastic protective cover, and the tops of the plurality of springs are all fixedly connected to the inner wall of the suspension body.

[0019] By adopting the above technical solution, the elastic protective cover is fixed to the top of the suspended machine body by several springs. When the electric push rod drives the camera to flip, the top plate on the outside of the camera first contacts the edge of the elastic protective cover and then pushes it upward until the camera flips upward and is completely placed inside it. With the spring rebounding and resetting, the elastic protective cover covers the outside of the camera, which plays a protective role and prevents the surging of air in the variable airflow environment from causing adverse effects on the camera and making the detection difficult.

[0020] Preferably, a connecting plate is fixedly connected to one side of the sliding block.

[0021] By adopting the above technical solution, the connecting plate is connected to the other side of the suspension body, and when the suspension body moves, it can push the sliding block and the electric push motor to move together.

[0022] In summary, this application includes at least one of the following beneficial technical effects of power line inspection drones with obstacle avoidance capabilities:

[0023] This power line inspection drone with obstacle avoidance function connects an electric push device to a suspension mechanism. When the drone encounters unstable airflow during power line inspection, the drive mechanism is activated to drive the suspension mechanism to move longitudinally along the lower limit component, causing the camera device to move in the same direction inward. At the same time, the electric push device moves along with it and, after activation, generates a pushing force on the camera device, causing it to flip upward and push the elastic protective mechanism upward before resetting. The flipped camera device is then wrapped inside the suspension mechanism to provide protection, preventing insufficient maneuverability of the drone and instability of the camera device in the event of changing airflow, which would otherwise lead to difficulties in inspection.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail below.

[0033] Example 1: A power line inspection drone with obstacle avoidance function, referring to... Figure 1 , Figure 2and Figure 3 The drone body 1 includes wings 2 on the outer surface of the drone body 1.

[0034] The drone body 1 has a rotatable balance frame 3 connected to both sides. A limit assembly 4 is located at the bottom of the drone body 1. A drive mechanism 5 is located inside the limit assembly 4. A suspension mechanism 6 is threadedly connected to the output end of the drive mechanism 5. A camera device 7 is rotatably connected to the inner wall of the suspension mechanism 6. An electric pushing device 8 is fixedly connected to one end of the suspension mechanism 6. The electric pushing device 8 is slidably connected to the outside of the limit assembly 4. An elastic protective mechanism 9 is fixedly installed inside the suspension mechanism 6. By connecting the electric pushing device 8 to the suspension mechanism 6, when the drone body 1 is performing power inspection... When encountering unstable airflow, the drive mechanism 5 is activated to drive the suspension mechanism 6 to move longitudinally along the lower part of the limiting component 4, causing the camera device 7 to move inward together. At the same time, the electric push device 8 moves and is activated, generating a pushing force on the camera device 7 to flip it upward and push the elastic protective mechanism 9 upward and reset it. The flipped camera device 7 is then wrapped inside the suspension mechanism 6 to provide protection and prevent the drone body 1 from becoming less maneuverable and the camera device 7 from becoming unstable and causing detection difficulties when encountering variable airflow.

[0035] Example 2: A power line inspection drone with obstacle avoidance function, referring to... Figure 4 , Figure 4 and Figure 6 The drive mechanism 5 includes a drive motor 501. A threaded shaft 502 is fixedly mounted on the output end of the drive motor 501. The threaded shaft 502 passes through the interior of the inner groove 402 and is threadedly connected to the suspension mechanism 6. The suspension mechanism 6 includes a suspension body 601. A limit slider is fixedly mounted on the top of the suspension body 601 and is threadedly connected to the threaded shaft 502. A suspension frame 602 is fixedly mounted on the bottom of the suspension body 601. The camera device 7 is rotatably mounted inside the suspension frame 602. Through the cooperation of the drive motor 501 and the threaded shaft 502, when the drive is started... When the motor 501 is in motion, the threaded shaft 502 rotates inside the inner groove 402 to drive the suspension mechanism 6 to move longitudinally along the lower part of the limiting base 401, thereby causing the camera device 7 to retract, reducing airflow through the space and avoiding adverse damage to the camera device 7. By extending the limiting slider into the inner groove 402, the motor 501 and the threaded shaft 502 work together to drive the limiting slider to slide, providing displacement driving force for the suspension body 601 and the suspension frame 602. When stationary, the suspension body 601 can provide stable suspension support for the camera device 7.

[0036] Example 3: A power line inspection drone with obstacle avoidance function, referring to... Figure 4 , Figure 5 and Figure 6 The camera device 7 includes a camera 701, with a top plate 702 on its outer surface. The top plates 702 are symmetrically arranged outside the camera 701. The camera 701 is located inside the suspension frame 602. The electric pushing device 8 includes an electric pushing motor 801, with a sliding block 802 fixedly installed on the top of the electric pushing motor 801. An electric push rod 803 is provided at the output end of the electric pushing motor 801. A connecting push plate 703 is rotatably connected to one end of the camera 701. The connecting push plate 703 is electrically powered. One end is rotatably connected to the output end of the electric push rod 803. The elastic protection mechanism 9 includes an elastic protective cover 901. Several springs 902 are fixedly installed on the top of the elastic protective cover 901. The tops of the springs 902 are all fixedly connected to the inner wall of the suspension body 601. By rotatably connecting the outer shell of the camera 701 to the inner side of the suspension frame 602, the camera 701 can have a flexible detection angle, and when the electric push device 8 pushes it to flip, it can flip upward and retract into the suspension frame 602. On the inside, to achieve the effect of inward protection, the electric push motor 801 drives the electric push rod 803 to extend and retract downward, thereby generating a pushing force on the connecting push plate 703. While pushing the connecting push plate 703 to gradually flip and move downward, it generates a one-way traction force on the camera 701. When the camera 701 flips, it pushes against the elastic protective mechanism 9 and retracts inward to its inside. This provides the flipping and inward driving force for the camera 701. Several springs 902 fix the elastic protective cover 901 to the top inside the suspension body 601. When the electric push rod 803 drives the camera 701 to flip, the top plate 702 on the outside of the camera 701 first contacts the edge of the elastic protective cover 901 and pushes it upward until the camera 701 flips upward and is completely placed inside it. With the springs 902 rebounding and resetting, the elastic protective cover 901 covers the outside of the camera 701, playing a protective role and preventing the surging of airflow in a variable airflow environment from adversely affecting the camera 701 and causing detection difficulties.

[0037] The implementation principle of this application embodiment is as follows: the sliding block 802 is connected to the suspension body 601 via the connecting plate 804. When encountering variable airflow, the drive motor 501 is started to drive the threaded shaft 502 to rotate, thereby driving the limiting slider to move along the inside of the inner groove 402. This causes the suspension body 601 and the sliding block 802 to slide together along the inner wall of the limiting groove 403. At this time, the camera 701 is driven to move towards the center of the limiting base 401. Simultaneously, the electric push motor 801 is started to drive the electric push rod 803 to extend and retract downwards, thereby pushing the connecting push plate 703 to gradually flip and move, and forming a traction force on the outer shell of the camera 701. This causes the detection end of the camera 701 to flip upwards to the inner side of the suspension frame 602, and cooperates with the top plate 702 at the edge to push the elastic protective cover 901, causing the spring 902 to contract and move upwards until the detection end of the camera 701 is placed below it. Then, the spring 902 rebounds and causes the elastic protective cover 901 to reset and cover the top of the camera 701 to form a protective state.

[0038] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
