Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power station defect detection, in particular to a photovoltaic power station patrol defect detection device. Background Art

[0002] Photovoltaic power plant inspection defect detection equipment refers to a series of tools and technologies specifically designed to inspect the health of photovoltaic modules (such as solar panels) in photovoltaic power plants. These devices help operators identify and locate defects and faults in PV modules, ensuring efficient plant operation. While the human eye can identify the location of defective wind turbine towers from visible light images, manual effort is limited when faced with massive amounts of visible light images and can easily lead to visual fatigue and misjudgment. Therefore, intelligent software systems are needed to automatically identify defective tower locations, followed by manual review, significantly improving efficiency and accuracy.

[0027] During inspections of photovoltaic power plants, maintenance personnel must regularly inspect and maintain fixed camera devices. This involves removing mounting bolts one by one, a time-consuming and tedious process that requires careful handling to avoid damage. After removal, the camera device must also be manually supported to prevent it from falling and causing damage, a safety risk. Therefore, the inventors have developed a photovoltaic power plant inspection defect detection device. This device, through its designed protective components, facilitates the installation and removal of the camera device, eliminating the tedious steps of removing bolts one by one and the need for manual support, significantly improving work efficiency and safety. These components not only simplify the operational process but also prevent the device from accidentally falling during removal, ensuring its safety, thereby addressing these drawbacks.

The outer surface of the threaded plate 25 is slidably connected to the inner cavity of the noise reduction box 21. The top of the movable plate 26 is movably provided with a shooting device 27. The shooting device 27 is composed of a camera, an infrared sensor and a remote information transmission and receiving module. Through the setting of the noise reduction box 21, it plays a role in reducing noise during the shooting process, thereby effectively avoiding the pollution of Gaussian noise, and the threaded plate 25 provides auxiliary support for the shooting device 27, so that it is convenient for the user to take out the shooting device 27;

[0030] Please refer to Figures 3 to 8 , both sides of the inner cavity of the installation box 22 are rotatably connected with rotating rods 28, and the outer surfaces of the two rotating rods 28 are fixedly connected with two meshing gears 29, and the bottom end of the rotating rod 28 passes through the inner cavity of the noise reduction box 21 and is fixedly connected with a push plate 210. The contact area between the rotating rod 28 and the noise reduction box 21 is sealed, and the left and right sides of the inner cavity of the noise reduction box 21 are slidably connected with limit plates 211, one side of the push plate 210 is connected to the outer surface of the push rod 212, and the bottom end of the push rod 212 is slidably connected to the outer surface of the limit plate 211. The shape of the limit plate 211 is T-shaped, and the outer surface of the limit plate 211 is provided with a sliding groove adapted to the push rod 212, and the outer surface of the limit plate 211 is in contact with the outer surface of the shooting device 27;

[0031] Please refer to Figures 2 to 8The inner cavity of the mounting box 22 is rotatably connected with a long rod 213, and the front end of the long rod 213 passes through the outside of the mounting box 22. The long rod 213 is connected to the outer surface of the rotating rod 28 with two meshing bevel gears 214. The outer surface of the long rod 213 is provided with a plurality of card holes 215. The outer surface of the mounting box 22 is fixedly connected with a welding block 216. A card rod 217 is provided on one side of the welding block 216. The outer surface of the card rod 217 is slidably connected to the outer surface of the mounting box 22. The opposite side of the card rod 217 and the welding block 216 is fixedly connected with a plurality of first return springs 218. The outer surface of the card rod 217 is matched with the card hole 215. The locking rod 217 is fixedly connected to the pull ring 219 at one end, and the outer surface of the mounting box 22 is fixedly connected to the second return spring 220. The end of the second return spring 220 away from the mounting box 22 is fixedly connected to the blocking rod 221, and the blocking rod 221 is used in conjunction with the pull ring 219. The left and right sides of the front side of the noise reduction box 21 are rotatably connected to the round rod 222. The outer surface of the round rod 222 is installed with a torsion spring 224. The outer surface of the round rod 222 is fixedly connected to a sealing plate 225. The outer surface of the sealing plate 225 contacts the outer surface of the shooting device 27. The sealing plate 225 is provided with an arc groove adapted to the shooting device 27.

[0032] Specifically, when the shooting device 27 needs to be taken out of the noise reduction box 21, the pull ring 219 is first manually pulled to move in the direction of the blocking rod 221. This action will drive the clamping rod 217 and the first return spring 218 to move and stretch together. When the clamping rod 217 is completely out of the clamping hole 215, the pull ring 219 is continued to be pulled until it contacts the blocking rod 221. At this time, the blocking rod 221 will compress the second return spring 220. Once the blocking rod 221 bounces into the inner side of the pull ring 219, it forms a blockage for the pull ring 219, preventing the clamping rod 217 from resetting. Then, the clamping rod 217 is rotated to drive the bevel gear 214, the gear 29, the rotating rod 28 and the push rod 212 to rotate together. The rotation of the push rod 212 will cause the limit plate 211 to move to both sides. This causes the limit plate 211 to move away from the shooting device 27. At this time, release the pull ring 219, allowing the first reset spring 218 to drive the locking rod 217 to reset and re-lock it in the locking hole 215. Next, manually rotate the torsion block to rotate the threaded rod 24. According to the principle of threaded transmission, the rotation of the threaded rod 24 will push the movable plate 26 forward, thereby driving the shooting device 27 to move forward synchronously. When the shooting device 27 moves and contacts the sealing plate 225, it will push the sealing plate 225 away, causing the round rod 222 to rotate and generate pressure on the torsion spring 224. Finally, the user can easily remove the shooting device 27 for necessary maintenance. Through the above steps, the shooting device 27 can be effectively removed while ensuring the stability and safety of all components during operation.

[0033] In summary, the working principle of a photovoltaic power station inspection defect detection device according to an embodiment of the present invention is as follows: first, the user operates the protective component 2 to install and place the shooting device 27, and then starts the drone 1 to inspect the photovoltaic power station, and starts the shooting device 27 to shoot the power station during the inspection, so as to achieve the purpose of defect detection. After shooting, the protective component 2 can be manually operated to conveniently take out the shooting device 27 from the protective component 2, and during the flight, the shooting device 27 can also be protected by the protective component 2 for easy use.
