Description

Technical Field

[0001] The utility model relates to the technical field of wind turbines, and particularly relates to a fault diagnosis device for a wind turbine. Background Technique

[0002] Wind power generation can not only provide electric energy required for human life, but also take into account environmental protection and the development of renewable energy. The existing wind power generation device utilizes the wind power from nature to drive the blades to rotate, and through the shaft work generated when the blades rotate, a generator is driven to generate electric energy. The blades are prone to wear during operation and are more likely to be damaged by external environments such as lightning, sand, rain, and hail, and need regular inspection and maintenance.

[0003] Upon retrieval, the publication (announcement) number: CN220687497U discloses a fault diagnosis device for a wind turbine, including a support frame for placing the wind blades. The support frame is arranged on a base. One side of the base along its length direction is provided with a side wall. The top plate is rotatably connected to the side plate above through a hinge. Multiple guide rails are opened on the top plate and the side plate along their length directions. The detector is connected to the guide rails through a driving mechanism. Before using this utility model, the top plate rotates 180 degrees upward to facilitate placing the wind blade. After the wind blade is placed on the support frame along the length direction of the base, the top plate rotates above the base. The detector is arranged on the guide rails opened on the side plate and the top plate and slowly moves on the guide rails driven by a motor. The multiple detectors provided can automatically move for detection. Similarly, after the back of the wind blade is manually flipped, detection is carried out, and the wind blade can be detected in all directions without omission, and the detection efficiency is improved.

[0004] Although the above solution can detect the wind blade in all directions without omission and improve the detection efficiency, it still requires manual flipping of the wind blade to perform all-round detection, and the working efficiency is low. Therefore, we propose a fault diagnosis device for a wind turbine. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a fault diagnosis device for a wind turbine, and by setting a flipping unit and a clamping unit, to solve the problem that manual flipping of the wind blade is required to perform all-round detection, resulting in low working efficiency.

[0006] A fault diagnosis device for a wind turbine includes a support unit, and further includes a detection unit and a flipping unit arranged inside the support unit, and a clamping unit arranged on the side of the flipping unit.

[0007] The flipping unit includes a hydraulic cylinder installed on the inner bottom wall of the support unit, a fixed block installed at the telescopic end of the hydraulic cylinder, a second rotating motor installed on the side wall of the fixed block, and a rotating shaft installed at the output end of the second rotating motor;

[0008] The clamping unit includes a flipping seat installed at the end of the rotating shaft and a clamping member arranged inside the flipping seat.

[0009] Preferably, the support unit includes a U-shaped seat and a base installed at the bottom of the U-shaped seat.

[0010] Preferably, the support unit further includes a support frame installed on the inner bottom wall of the U-shaped seat.

[0011] Preferably, the detection unit includes a fixed seat installed on the inner top wall of the U-shaped seat, a threaded shaft movably arranged inside the fixed seat, a first driving motor installed at the input end of the threaded shaft, and a detection member arranged on the side of the threaded shaft.

[0012] Preferably, the detection member includes a moving member installed on the circumferential side of the threaded shaft and a detector installed at the bottom of the moving member.

[0013] Preferably, the detection unit further includes a limit washer installed on the inner side wall of the U-shaped seat, and the limit washer is sleeved on the circumferential side of the threaded shaft.

[0014] Preferably, the clamping member includes an electric telescopic rod installed on the inner top wall of the flipping seat and a clamping plate installed at the telescopic end of the electric telescopic rod.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In the utility model, through the arranged flipping unit and clamping unit, when it is necessary to detect a wind power generation blade, first place the blade on the support frame, and the first driving motor drives the threaded shaft to rotate. At this time, the moving member drives the detector to move along the threaded shaft, and the detector detects and diagnoses the surface of the power generation blade; when the detection of one side of the power generation blade is completed, the telescopic end of the electric telescopic rod extends, so that the clamping plate presses against the power generation blade and cooperates with the flipping seat for stable clamping. Subsequently, the telescopic end of the hydraulic cylinder extends, the second rotating motor drives the rotating shaft to rotate, and the rotating shaft drives the flipping seat to perform a 180-degree flip. Then, the telescopic end of the hydraulic cylinder contracts until the power generation blade is located on the support frame again and then stops, and the detection action is continued to be repeated, so that the power generation blade can be detected in all directions without manual turning, improving the work efficiency.
