Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic inspection drone technology, specifically relating to a convenient replaceable inspection component for photovoltaic inspection drones. Background Technology

[0002] The drone photovoltaic inspection system is based on drones equipped with dual-light (infrared / visible light) high-definition cameras. Following a path planned by a specific algorithm, it scans and photographs photovoltaic power stations. The dual-light image data is preprocessed by an image intelligent recognition module, and hot spot and cell tracking models are trained using AI deep learning algorithms. Based on image stitching technology and RTK high-precision positioning, it realizes automatic fault diagnosis technology for photovoltaic modules.

[0003] It can detect abnormalities such as dirt, cracks, shading, and overheating in large-area photovoltaic modules, and generate inspection reports including the precise location and detailed information of the fault. It is a new generation of efficient and intelligent inspection and diagnosis solution for photovoltaic power plants.

[0004] The gimbal is an important component for mounting the dual-light camera. It can rotate horizontally and flip vertically. It is usually fixed to the bottom of the drone body with bolts. Although this can ensure the stability of the installation, it requires tools to install and remove, which is not convenient and is not conducive to carrying and maintenance.

[0005] A search revealed that Chinese utility model patent CN216546757U discloses "an infrared information acquisition mechanism for a photovoltaic inspection drone," which includes a base fixed to the bottom of the photovoltaic inspection drone. The base has a slot inside, and a slot is provided on one side of the slot. A buffer device is provided at the bottom of the base, and a card plate is fixedly connected to the top of the buffer device. The card plate is adapted to the slot. A three-axis gimbal is fixedly connected to the bottom of the buffer device, and a dual-light camera is provided at the bottom of the three-axis gimbal.

[0006] Existing photovoltaic inspection drones, including those mentioned above, can disassemble their infrared information acquisition mechanisms by pulling down a fixed plate. While this facilitates the installation and disassembly of the infrared information acquisition mechanism, external forces can easily cause the fixed plate to move erroneously, resulting in insufficient stability of the acquisition mechanism during installation.

[0007] To address the aforementioned issues, this utility model proposes a convenient replaceable inspection component for photovoltaic inspection drones. Utility Model Content

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] Please see Figures 1-4 This utility model provides the following technical solution: a convenient replaceable inspection component for photovoltaic inspection drones, including a connecting plate 1, a gimbal 2 located at the bottom of the connecting plate 1, and a high-definition camera 3 located at the end of the gimbal 2. It also includes: a mounting plate 6 fixed above the connecting plate 1, and a base plate 7 detachably connected to the mounting plate 6 by a locking mechanism 8. The base plate 7 is fixed to the bottom surface of the photovoltaic inspection drone. The locking mechanism 8 includes: a fixing frame 81 fixed to the top surface of the mounting plate 6, two moving plates 82, an L-shaped locking block 83 fixed to the bottom end of the moving plates 82, and a control mechanism 84. The control mechanism 84 is used to control the two moving plates 82 to move in opposite directions. It includes: two symmetrically distributed fixing plates 841 fixed to the bottom surface of the base plate 7, and a bidirectional threaded screw 842 rotatably installed between the two fixing plates 841. The bidirectional threaded screw 842 is threadedly engaged with the moving plates 82.

[0046] Furthermore, by Figures 1-3As shown in this embodiment, a guide sliding hole 811 is provided on the fixed frame 81, two movable plates 82 are movably connected to the base plate 7, and an L-shaped locking block 83 passes through the guide sliding hole 811. After adopting the above solution, when installing the gimbal 2, the base plate 7 is first fixed to the bottom surface of the photovoltaic inspection drone with bolts.

[0047] Align the guide slide hole 811 on the fixing bracket 81 with the L-shaped locking block 83, and then make the L-shaped locking block 83 pass through the guide slide hole 811. At this time, the horizontal part of the L-shaped locking block 83 passes through the guide slide hole 811.

[0048] Then rotate the bidirectional threaded screw 842. Since the bidirectional threaded screw 842 has two external threads with opposite directions, and the bidirectional threaded screw 842 is threadedly connected to the moving plate 82, when the bidirectional threaded screw 842 rotates in the forward direction, it can drive the two moving plates 82 to move in the opposite direction, and at the same time drive the L-shaped locking block 83 at the bottom to move until the L-shaped locking block 83 moves to the end of the guide slide hole 811. At this time, the horizontal part of the L-shaped locking block 83 and the fixed frame 81 form a locking engagement.

[0049] Rotate the bidirectional threaded screw 842 in the opposite direction to make the two moving plates 82 move towards each other under the action of the threaded screw, and drive the two L-shaped locking blocks 83 to move closer to the inside. When the L-shaped locking blocks 83 move to the inside of the guide slide hole 811, the gimbal 2 can be removed.

[0050] This invention allows for quick assembly and disassembly by rotating the bidirectional threaded screw 842 to move the two L-shaped locking blocks 83 toward or in opposite directions, eliminating the need for tools and significantly improving maintenance efficiency. The bidirectional threaded screw 842 is threadedly engaged with the moving plate 82, and the external thread of the bidirectional threaded screw 842 meshes with the internal thread of the moving plate 82, providing a self-locking effect. The moving plate 82 cannot move when the bidirectional threaded screw 842 is not rotating, ensuring the stability of the installation.

[0051] Preferably, by Figures 1-3 As shown in this embodiment, there are two sets of locking mechanisms 8 symmetrically distributed. After adopting the above scheme, when in use, the two sets of locking mechanisms 8 jointly bear the weight of the detection component and the vibration and aerodynamic load during the flight of the UAV, avoiding the off-center load or tilt caused by the force of a single set, improving the connection stiffness, and avoiding structural deformation or loosening caused by the force of a single point.

[0052] Preferably, by Figures 1-3As shown in this embodiment, the outer wall of the L-shaped locking block 83 is attached to the inner wall of the guide sliding hole 811. With the above solution, when the control mechanism 84 drives the bidirectional threaded screw 842 to rotate, causing the two moving plates 82 to move, the L-shaped locking block 83 moves synchronously with the moving plates 82. Since the outer wall of the L-shaped locking block 83 is attached to the inner wall of the guide sliding hole 811, the guide sliding hole 811 provides precise guidance for the L-shaped locking block 83. During the movement, the L-shaped locking block 83 can only move in a straight line along the inner wall of the guide sliding hole 811, and there will be no left or right swaying or deviation.

[0053] Moreover, the close fit design ensures that the friction between the L-shaped locking block 83 and the guide slide hole 811 is evenly distributed. This uniform friction can buffer the impact force of the L-shaped locking block 83 during movement, avoiding damage to components or insecure locking caused by excessive impact force.

[0054] Preferably, by Figures 1-3 As shown, in this embodiment, the control mechanism 84 further includes a handle 843, which is fixed to one end of the bidirectional threaded screw 842. With the above solution, the handle 843 provides a force application point for the operator during use, making it convenient for the operator to rotate the bidirectional threaded screw 842 through the handle 843.

[0055] Preferably, by Figures 1-3 As shown in this embodiment, the control mechanism 84 further includes: guide rods 844. Two guide rods 844 are symmetrically fixed between two fixed plates 841 and pass through the moving plate 82. With the above solution, during use, the moving plate 82 is supported and guided by the two guide rods 844, which further improves the stability of the moving plate 82.

[0056] Preferably, by Figures 1-3 As shown, in this embodiment, the locking mechanism 8 further includes two symmetrically distributed L-shaped locking blocks 85 fixed to the bottom surface of the base plate 7. A positioning through hole 812 is provided on the fixing frame 81 for the L-shaped locking blocks 85 to pass through. When the L-shaped locking block 83 moves to the farthest position along the guide sliding hole 811, it engages with the L-shaped locking block 85. With the above solution, in use, the installation position of the gimbal 2 is positioned by the set L-shaped locking blocks 85. When the L-shaped locking block 85 passes through the positioning through hole 812, the installation position of the gimbal 2 can be positioned.

[0057] When the L-shaped locking block 83 moves to the farthest position along the guide sliding hole 811, it engages with the L-shaped locking block 85. At this time, the L-shaped locking block 83 and the L-shaped locking block 85 form a double lock, which further improves the stability of the positioning gimbal 2 installation.

[0058] Preferably, by Figure 1As shown, this embodiment further includes: multiple adapter plates 4 evenly spaced along the circumferential direction fixed to the bottom surface of the connecting plate 1, and support columns 5 fixed to the top surface of the adapter plates 4. The mounting plate 6 is fixed to the top of the support column 5. With the above solution, in use, the multiple adapter plates 4 and support columns 5 evenly spaced along the circumferential direction form a uniform support system. This layout allows the weight borne by the connecting plate 1 from components such as the gimbal 2 and the high-definition camera 3 to be evenly distributed on the mounting plate 6, avoiding excessive local stress.

[0059] During the flight of the photovoltaic inspection drone, it will encounter various complex airflows and vibrations. These external forces will affect the detection components. Since the adapter plate 4 and the support column 5 are evenly distributed around the circumference, they can work together to resist the external forces and maintain the stability of the detection components.

[0060] The adapter plate 4 serves as a transition component between the connecting plate 1 and the support column 5, enhancing the reliability of the connection.

[0061] Meanwhile, the presence of the adapter plate 4 also brings a certain degree of flexibility to the entire structure. If it is necessary to repair or replace some parts of the detection component, the connection between the adapter plate 4 and the connecting plate 1 or the support column 5 can be disassembled for easy operation. The locking mechanism 8 can also be released for disassembly.

[0062] Preferably, by Figure 1 As shown, in this embodiment, it further includes a rubber block 9 fixed between the connecting plate 1 and the adapter plate 4. With the above solution, when in use, the adapter plate 4 and the connecting plate 1 are fixed with rigid bolts. By adding a rubber block 9 on the inner side of both, the rubber block 9 is flexible. When the connecting plate 1 shakes or shifts due to airflow, the rubber block 9 contracts to buffer, which further improves the safety and stability of the detection component.

[0063] Preferably, by Figures 1-4 As shown, this embodiment further includes: a push plate 10, multiple telescopic columns 11, and a telescopic spring 12. The push plate 10 is located below the base plate 7. The multiple telescopic columns 11 are fixed at equal intervals between the base plate 7 and the push plate 10. The telescopic spring 12 is sleeved on the telescopic column 11. The telescopic column 11 is a telescopic structure composed of two hollow cylindrical components sleeved together. After adopting the above scheme, when the mounting plate 6 of the detection component approaches the base plate 7 during use, the push plate 10 first contacts the mounting plate 6 and is forced to compress the telescopic spring 12 due to the obstruction of the mounting plate 6. At this time, the distance between the base plate 7 and the push plate 10 is reduced.

[0064] The elastic force of the telescopic spring 12 will actively apply a downward auxiliary force, making the push plate 10 fit more tightly with the mounting plate 6. At the same time, the positive pressure of the engagement surface of the fixing frame 81, L-shaped locking block 83 and L-shaped latch 85 increases, which counteracts the slight sinking of the base plate 7 caused by aerodynamic lift fluctuations during the flight of the UAV, and effectively prevents the L-shaped locking block 83 from loosening.

[0065] Components not described in detail in this article are existing technologies.

[0066] The working principle and usage process of this utility model: When using the convenient replaceable detection component of this utility model, first fix the base plate 7 to the bottom surface of the photovoltaic inspection drone with bolts;

[0067] Align the guide slide hole 811 on the fixing bracket 81 with the L-shaped locking block 83, and then make the L-shaped locking block 83 pass through the guide slide hole 811. At this time, the horizontal part of the L-shaped locking block 83 passes through the guide slide hole 811.

[0068] Then rotate the bidirectional threaded screw 842. Since the bidirectional threaded screw 842 has two external threads with opposite directions, and the bidirectional threaded screw 842 is threadedly connected to the moving plate 82, when the bidirectional threaded screw 842 rotates in the forward direction, it can drive the two moving plates 82 to move in the opposite direction, and at the same time drive the L-shaped locking block 83 at the bottom to move until the L-shaped locking block 83 moves to the end of the guide slide hole 811. At this time, the horizontal part of the L-shaped locking block 83 and the fixed frame 81 form a locking engagement.

[0069] Rotate the bidirectional threaded screw 842 in the opposite direction to make the two moving plates 82 move towards each other under the screw rotation action, and drive the two L-shaped locking blocks 83 to move closer to the inside. When the L-shaped locking blocks 83 move to the inside of the guide slide hole 811, the gimbal 2 can be removed.

[0070] This invention allows for quick assembly and disassembly by rotating the bidirectional threaded screw 842 to move the two L-shaped locking blocks 83 toward or in opposite directions, without the need for tools, thus greatly improving maintenance efficiency. The bidirectional threaded screw 842 is threadedly engaged with the moving plate 82, and the external thread of the bidirectional threaded screw 842 meshes with the internal thread of the moving plate 82, providing a self-locking effect. The moving plate 82 cannot move when the bidirectional threaded screw 842 is not rotating, ensuring the stability of the installation.

[0071] In another aspect of this utility model, due to the setting of the L-shaped locking block 85, the L-shaped locking block 85 positions the installation position of the gimbal 2. When the L-shaped locking block 83 moves to the farthest position along the guide sliding hole 811, it engages with the L-shaped locking block 85. At this time, the L-shaped locking block 83 and the L-shaped locking block 85 form a double lock, which further improves the stability of the gimbal 2 installation.

[0072] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
