Abstract
Description
Technical Field
[0001] This invention relates to the field of wind turbine blade testing technology, specifically a fixing device for testing wind turbine blade systems. Background Technology
[0002] Against the backdrop of the rapid development of the wind power industry, wind turbine blades, as the core components of wind turbine generators, directly affect the operational safety and power generation efficiency of the units due to their structural integrity. Wind turbine blades are exposed to complex natural environments for a long time and are prone to defects such as cracks, delamination, and damage due to factors such as airflow impact, ultraviolet radiation, and temperature changes. Therefore, it is necessary to conduct precise inspections on them regularly and promptly identify potential safety hazards.
[0003] Currently, wind turbine blade inspections largely rely on manual handheld inspection equipment or simple fixed inspection devices. Traditional inspection devices often use fixed tracks or manually adjustable structures, which can only achieve positional movement in one direction. This makes it difficult to accurately locate the inspection position in different areas of the wind turbine blade. Especially for large blades, the horizontal adjustment accuracy is low and the stroke is limited, resulting in low inspection efficiency. At the same time, since the surface of wind turbine blades is mostly complex curved and has many hidden parts, traditional inspection probes are mostly designed with fixed angles. They cannot flexibly adjust the inspection posture according to the shape of the blade surface, which easily leads to blind spots and cannot fully cover the entire inspection range of the blade. Therefore, there is a need to provide a fixed device for the inspection of wind turbine blade systems. Summary of the Invention
[0004] The purpose of this invention is to provide a fixing device for wind turbine blade system inspection, addressing the problems mentioned in the background art. Because wind turbine blade surfaces are mostly complex curved surfaces with many hidden areas, traditional inspection probes are often designed with fixed angles, unable to flexibly adjust their inspection posture according to the blade's surface shape, easily resulting in blind spots and failing to fully cover the entire inspection range of the blade. To achieve the above objective, this invention provides the following technical solution: a fixing device for wind turbine blade system inspection, comprising a support frame; The detection assembly includes a drive motor for adjusting the detection position. The drive motor is fixedly connected to one side of a support frame. A threaded rod is fixedly connected to the transmission end of the drive motor. A sliding groove is formed at the top of the support frame, and a slider is movably connected to the inner wall of the groove. The threaded rod is threadedly connected inside the slider. A detection frame is mounted on the top of the slider. A movable groove is formed at the bottom of the detection frame, and a movable block is movably connected to the inner wall of the groove. A connecting screw is threadedly connected inside the movable block. An electric actuator is fixedly connected to the bottom of the movable block, and a connecting seat is fixedly connected to the bottom of the electric actuator. A universal ball is installed inside the connecting seat, and an ultrasonic probe is fixedly connected to the side surface of the universal ball. By installing the detection assembly, during detection, the drive motor drives the threaded rod to rotate, thereby enabling the detection to... The top-mounted inspection frame allows for horizontal position adjustment, enabling it to move to the corresponding horizontal position of the wind turbine blade's inspection area. During inspection, an external motor drives the connecting screw to rotate, which in turn moves the bottom electric actuator and ultrasonic probe to adjust their left and right positions. The electric actuator also moves the ultrasonic probe closer to the wind turbine blade for inspection. The universal ball joint inside the connecting seat allows for multi-directional rotation, enabling the ultrasonic probe fixed to its side surface to flexibly adjust the inspection angle. This multi-dimensional adjustment structure allows for precise control of the inspection position from all angles. The universal ball joints 1 and 2 allow the probe to flexibly rotate, precisely conforming to the complex curved surface or hidden parts of the blade to ensure the inspection range covers the entire blade, avoiding blind spots. A fixing assembly includes a fixing frame for support, the fixing frame being fixedly connected to the top of a support frame, an adjusting seat being fixedly connected to the top of the fixing frame, a universal ball bearing being installed inside the adjusting seat, and a vacuum suction cup being fixedly connected to the side surface of the universal ball bearing. The mounting assembly includes a limiting block for mounting, the limiting block being fixedly connected to the top of the slider, and a threaded hole being provided on one side of the limiting block.
[0005] More preferably, the detection component further includes a connecting groove, which is formed on one side of the detection frame. A connecting block is movably connected to the inner wall of the connecting groove, and a connecting screw is threadedly connected to the inner wall of the connecting block.
[0006] More preferably, the detection assembly further includes an electric actuator second, which is fixedly connected to one side of the connecting block. One end of the electric actuator second is equipped with a universal ball joint second, and an ultrasonic probe second is fixedly connected to the side surface of the universal ball joint second.
[0007] More preferably, the fixing assembly further includes an adjusting seat two, which is fixedly connected to the top of the fixing frame. The adjusting seat two has a universal ball bearing two installed inside, and a vacuum suction cup two is fixedly connected to the side surface of the universal ball bearing two. By installing the fixing assembly, when fixing the wind turbine blade, the suction posture of the vacuum suction cup one and the vacuum suction cup two can be adjusted by rotating the universal ball bearing one and the universal ball bearing two according to the shape and detection requirements of the wind turbine blade, so that the two suction cups can be tightly attached to the surface of the wind turbine blade. Then, the vacuum suction cup is activated to generate negative pressure, and atmospheric pressure is used to firmly suction and fix the wind turbine blade, avoiding displacement or shaking of the blade during the detection process and ensuring detection accuracy.
[0008] More preferably, the mounting assembly further includes a limiting groove, which is formed at the bottom of the testing frame. The limiting block is adapted to the limiting groove and is movably connected to the inner wall of the limiting groove. The testing frame is internally threaded with a fixing rod, which is threaded into the inside of a threaded hole.
[0009] More preferably, a support rod one is fixedly connected to the bottom of the fixing frame, and a support rod two is fixedly connected to the bottom of the fixing frame.
[0010] More preferably, the bottom of the support frame is fixedly connected to a support leg, and the bottom of the support leg is fixedly connected to an anti-slip pad.
[0011] More preferably, the threaded rod is movably connected inside the support frame, and the threaded rod is disposed on the inner wall of the slide groove.
[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, by installing a detection component, a drive motor rotates a threaded rod during detection, thereby adjusting the horizontal position of the top detection frame. This allows the detection frame to move to the corresponding horizontal position of the wind turbine blade's inspection area. Simultaneously, an external motor rotates a connecting screw, causing a movable block to adjust the left and right positions of the bottom electric actuator and ultrasonic probe. The electric actuator also moves the ultrasonic probe closer to the wind turbine blade for inspection. A universal ball joint inside the connecting seat allows for multi-directional rotation, enabling flexible adjustment of the detection angle of the ultrasonic probe fixed to its side surface. This multi-dimensional adjustment structure allows for precise, all-around control of the detection position. Furthermore, universal balls one and two allow for flexible probe rotation, precisely conforming to the complex curved surfaces or hidden areas of the blade, ensuring the detection range covers the entire blade and avoiding blind spots.
[0013] In this invention, by installing a fixing component, when fixing the wind turbine blade, the adsorption posture of the vacuum suction cups can be adjusted by rotating the universal ball bearings 1 and 2 according to the shape and contour of the wind turbine blade and the testing requirements. This allows the two suction cups to fit tightly against the surface of the wind turbine blade. Then, the vacuum suction cups are activated to generate negative pressure, using atmospheric pressure to firmly adsorb and fix the wind turbine blade, preventing displacement or shaking of the blade during the testing process and ensuring testing accuracy.

By installing the fixing component 3, when fixing the wind turbine blade, the suction posture of the vacuum suction cup 304 and the vacuum suction cup 307 can be adjusted by rotating the universal ball bearing 303 and the universal ball bearing 306 according to the shape and inspection requirements of the wind turbine blade, so that the two suction cups can be tightly attached to the surface of the wind turbine blade.

[0025] The method of use and advantages of the present invention: The fixing device for wind turbine blade system testing operates as follows: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, during testing, the drive motor 201 rotates the threaded rod 202, thereby adjusting the horizontal position of the top testing frame 205.

Simultaneously, an external motor rotates the connecting screw 208, causing the movable block 207 to adjust the left and right positions of the bottom electric actuator 209 and ultrasonic probe 212. The electric actuator 209 also moves the ultrasonic probe 212 closer to the wind turbine blade for testing. The universal ball joint 211 installed inside the connecting seat 210 allows for multi-directional rotation. The ultrasonic probe 212, fixed on its side surface, can be flexibly adjusted to change the detection angle. Through the multi-dimensional adjustment structure, the detection position can be precisely controlled in all directions. The probe can be flexibly rotated by the universal ball 211 and universal ball 217. When fixing the wind turbine blade, the suction posture of the vacuum suction cup 304 and vacuum suction cup 307 can be adjusted by rotating the universal ball 303 and universal ball 306 according to the shape and detection requirements of the wind turbine blade. This allows the two suction cups to fit tightly against the surface of the wind turbine blade. Then, the vacuum suction cup 304 and vacuum suction cup 307 are activated to generate negative pressure, using atmospheric pressure to firmly attach and fix the wind turbine blade.
