Description

Technical Field

[0001] This utility model relates to the field of inspection technology, specifically an integrated image acquisition device for unmanned aerial vehicle (UAV) inspection of wind turbine blades. Background Technology

[0002] The integrated image acquisition device for wind turbine blade drone inspection can be designed as a compact device equipped with a high-precision industrial camera, multi-modal light source, intelligent supplementary lighting system, and integrated control module. Combined with drone autonomous flight control and AI algorithms, it achieves millimeter-level detection and automated inspection of blade defects. Specifically, it employs a high-resolution (e.g., 120 million pixels) CMOS sensor to ensure image clarity and capture minute defects on the blade surface. The camera features a panoramic shutter function, capable of capturing high-speed moving objects without distortion, suitable for inspecting wind turbine blades in both dynamic and static conditions. However, the surface of wind turbine blades is a complex curved surface. Traditional drone-mounted cameras have a relatively small angle, allowing only limited angle adjustment. Due to the large size of the blades, they may fail to capture details in critical areas such as blade edges, roots, or the windward side, leading to missed defects. Utility Model Content

The angle can be adjusted to a suitable angle as needed, which greatly improves the angle adjustment range. The required position can be monitored without passing through the dangerous parts of the fan blades, making it more convenient and safer.

[0024] The end of the connecting rod 58 is fixedly connected to the mounting plate 6. The front of the mounting plate 6 has an adapter hole 7 and four positioning holes 8. A quick disassembly mechanism 9 is provided between the mounting plate 6, the adapter hole 7 and the four positioning holes 8.

The acquired images are transmitted to the ground flight controller through wireless communication technology, which is existing technology and will not be described in detail in this article. The main body of the acquisition device 1 is electrically connected to an external power supply and is controlled by an external program.

[0030] The working principle of this utility model is as follows: First, insert the four positioning plugs 93 and the connecting plate 92 into the inner walls of the four positioning holes 8 and the adapter holes 7 respectively. Then, initially install the support plate 95 and the main body 1 of the acquisition device on its front side onto the mounting plate 6. Next, insert the two insert plates 91 between the inner walls on both sides of the mounting plate 6 and the inner wall of the connecting plate 92. Then, tighten the four bolts 94 to thread-fix the two connecting plates 92, the two insert plates 91, and the mounting plate 6 together. Then, the drone pilot controls the drone to perform inspections, while simultaneously remotely controlling the start of the first motor 51, causing the first motor 51 to drive the output end of the... When the first rotating bar 54 rotates, it presses and drives the connecting rod 58, causing the connecting rod 58 to move left and right along the inner wall of the second rotating bar 55. Then, the second motor 56 is started, causing the second rotating bar 55 at the output end to rotate. When the second rotating bar 55 rotates, it presses and drives the connecting rod 58, causing the connecting rod 58 to move up and down along the inner wall of the first rotating bar 54. By adjusting the left and right plus up and down movements, the connecting rod 58 can arbitrarily drive all the structures on its front, including the acquisition device body 1, to adjust the angle to the required angle for corresponding monitoring.
