Description
Technical Field
[0001] This utility model relates to the field of drone detection technology, and in particular to a drone detection device for photovoltaic modules. Background Technology
[0002] A photovoltaic module drone inspection device is a machine mounted on a drone for inspecting photovoltaic power plant modules. Its core components consist of an infrared thermal imager and a visible light camera, which simultaneously acquire thermal infrared and external images of the modules to identify defects such as hot spots, microcracks, and breakage. The device is often integrated into a gimbal, allowing for flexible adjustment of the shooting angle to adapt to different photovoltaic array arrangements. As the drone flies along a preset route, the device transmits data in real time, generating analysis reports based on geographic information. This method is more efficient than manual inspection and is particularly suitable for automated inspection of large-area, complex terrain power plants.
[0003] The photovoltaic module drone inspection device operates by carrying an infrared thermal imager and a visible light camera. As the drone flies along a preset route, the infrared thermal imager captures the temperature distribution of the modules, identifying heat anomalies such as hot spots and microcracks; the visible light camera photographs the exterior, detecting glass breakage, dust accumulation, and other defects. Data from both cameras is collected synchronously and transmitted to a ground station. Combined with the gimbal's adjusted shooting angle and the drone's positioning information, software fusion analysis generates a visual report on the location and type of defects, enabling automated and high-precision inspection of photovoltaic modules.
[0004] In existing technologies, the gimbal of some photovoltaic module drone testing devices is fixed inside the drone. When the gimbal is damaged and needs to be disassembled, the drone must be removed first. This makes the disassembly process complicated, time-consuming, and affects maintenance efficiency. Repeated disassembly can easily damage the drone's shell clips, internal cables, and other components, reducing equipment reliability. If the drone has a compact structure, other sensors, drone testing technologies, or circuit boards may be accidentally touched during disassembly or assembly, causing additional malfunctions. Gimbal malfunctions that could be repaired independently are expanded due to disassembly, increasing the scope of maintenance, maintenance costs, and downtime. Therefore, a photovoltaic module drone testing device is proposed to solve the above problems. Utility Model Content

[0012] Reference Figure 2 , Figure 3 and Figure 6 This utility model provides an embodiment of a photovoltaic module drone testing device, including a fixed plate 1. The fixed plate 1 provides the fixing conditions for a gimbal 8 and is connected to a shock-absorbing component. Two discs 2 are fixedly connected to the top of the fixed plate 1. Springs 3 are fixedly connected inside the top of each disc 2. A pressure plate 4 is fixedly connected to the other end of each spring 3. The upper and lower ends of the springs 3 are respectively fixed inside the top of the disc 2 and the top of the pressure plate 4, so that the pressure plate 4 can generate pressure, thereby pressing the fixing rod 7 into the interior of the fixed plate 1. Two fixing columns 6 are slidably connected inside the fixed plate 1. Two fixing rods 7 are fixedly connected to the outside of the top of each fixing column 6. The bottom of each fixing column 6 is rotatably connected to a gimbal 8. The bottom of the fixing column 6 is equipped with the gimbal 8 and the top of the fixing column 8 is fixed with two fixing rods 7. The gimbal 8 is fixed through the fixing columns 6. A shock-absorbing component is fixedly connected to the top of the fixed plate 1. The shock-absorbing component blocks the transmission of vibration, making the fixed plate 1 stable.
[0013] A cylinder 5 is fixedly connected to the top of the pressure plate 4. The inside of the spring 3 is fitted onto the outside of the cylinder 5. The cylinder 5 is used to limit the spring 3, so that the spring 3 only generates force in the vertical direction. The outside of the pressure plate 4 is slidably connected to the inside of the fixed plate 1. The bottom of the pressure plate 4 is connected to the top of the two fixed rods 7. The outside of the two fixed rods 7 is slidably connected to the inside of the fixed plate 1. The bottom of the fixed plate 1 is provided with a sliding groove 24. The sliding groove 24 facilitates the fixed rods 7 to enter the inside of the fixed plate 1 and rotate. When the fixed rods 7 rotate, they find the slot inside the fixed plate 1 and enter the slot to cooperate with the pressure plate 4 to complete the fixation. One of the pan-tilt units 8 is rotatably connected to a visible light camera 9, and the other pan-tilt unit 8 is rotatably connected to an infrared camera 10. The visible light camera 9 is used to take normal pictures, and the infrared camera 10 is used to take infrared pictures.
[0014] Reference Figure 1 , Figure 4 and Figure 5The vibration damping assembly includes two connecting plates 11, the bottom ends of which are fixedly connected to the top of a fixed plate 1. Multiple springs 13 are fixedly connected to the top of each connecting plate 11. A cylinder 12 is fitted inside the bottom end of each spring 13, and a cylinder 15 is fitted inside the top of each spring 13. A connecting plate 14 is fixedly connected to the top of each spring 13. Springs 13 and cylinders 12 are installed on the top of the connecting plate 11, and springs 13 and cylinders 15 are installed on the bottom of the connecting plate 14. When vibration is transmitted to the connecting plate 14, springs 13 absorb the vibration and cancel it out through the absorbed kinetic energy. Two fixed blocks are fixedly connected to both the left and right ends of the connecting plate 11. Two fixing blocks 17 are fixedly connected to both ends of the connecting plate 16. A shock-absorbing rod 18 is rotatably connected to the adjacent side of the two fixing blocks 16. A rotating shaft 20 is fixedly connected to the other end of the shock-absorbing rod 18. A shock-absorbing rod 19 is rotatably connected to the adjacent side of the two fixing blocks 17. The spring 13 absorbs and cancels the vibration while transferring some kinetic energy to the shock-absorbing rod 18 and the shock-absorbing rod 19. The rotating shaft 20 fixedly connected to the shock-absorbing rod 18 causes the shock-absorbing rod 19 to rotate, thereby reducing the vibration. A shock-absorbing plate 21 is fixedly connected to the top of the connecting plate 14. A connecting block 22 is fixedly connected to the top of the shock-absorbing plate 21. The shock-absorbing plate 21 is fixed to the UAV body 23 through the connecting block 22.
[0015] The bottom ends of multiple cylinders 12 are fixedly connected to the top end of connecting plate 11, the top ends of multiple cylinders 15 are fixed to the bottom end of connecting plate 14, the other end of shock absorber rod 19 is rotatably connected to the outside of rotating shaft 20, and the top end of connecting block 22 is fixedly connected to UAV body 23, which is the main body of the entire device.
[0016] Working principle: When the gimbal 8 is damaged and needs to be disassembled, press the gimbal 8 upwards to make the fixing column 6 move upwards. The movement of the fixing column 6 drives the fixing rod 7 to move upwards. The upward movement of the fixing rod 7 drives the pressure plate 4 to move upwards. Rotating the gimbal 8 causes the fixing column 6 to rotate. The movement of the fixing column 6 drives the fixing rod 7 to rotate. When the fixing rod 7 rotates to the slide groove 24, it moves the gimbal 8 downwards, thereby completing the disassembly of the gimbal 8 and realizing the replacement of the gimbal 8.
[0017] When the drone body 23 is working, the vibration generated by the drone body 23 is transmitted to the damping plate 21 through the connecting block 22, and then to the connecting plate 24 through the damping plate 21. The connecting plate 24 transmits the vibration to the spring 23, the damping rod 29 and the damping rod 18, so that the vibration is converted into the kinetic energy of the spring 23. The elastic potential energy of the spring 213 cancels out the vibration of the drone body 23, so that the vibration generated by the drone body 23 cannot be transmitted to the visible light camera 9 and the infrared camera 10, thereby improving the image clarity.
[0018] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
