Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, specifically a wind turbine fan blade positioning device. Background Technology

[0002] During operation, wind turbine blades accumulate rainwater and dew, leading to increased weight and structural damage. Therefore, drainage holes are usually installed at the blade tips. However, since the blade tips are curved, the drill bit is prone to slipping and damaging the blades when drilling. To address these issues, a wind turbine blade positioning device is proposed.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A wind turbine blade positioning device includes a base, on which a rotating arm is symmetrically rotatably connected via a pin. A Y-shaped frame is fixedly connected to the end of the rotating arm. A suction cup assembly is rotatably connected inside the Y-shaped frame. A connecting pipe is rotatably connected inside the base. A square tube is slidably connected inside the connecting pipe. A screw is threadedly connected inside the square tube. A guide sleeve is fixedly connected to one end of the connecting pipe. The square tube slides through the guide sleeve, and the other end of the square tube outside the guide sleeve slides through an L-shaped bracket. A first fixing bolt is threaded through one side of the square tube. A guide head is provided at the end of the L-shaped bracket. A guide hole is provided through the guide head. A worm gear is coaxially fixedly connected to the other end of the connecting pipe outside the base. A worm gear meshing with the worm gear is rotatably connected to the side wall of the base. A first rotating cap is fixedly connected to the end of the worm gear. One end of the screw gear is rotatably connected to the inner wall of the connecting pipe. A second rotating cap is fixedly connected to the end of the screw gear near the worm gear.

[0009] As a further improvement of this utility model: a rubber pad is provided in the slot, and the rubber pad extends to the side wall of the base.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. In use, this utility model involves attaching the base sidewall to the end of the wind turbine blade that needs drilling, rotating the rotating arm, and using the suction cup assembly on the Y-shaped frame fixedly connected to the end of the rotating arm to adhere to the surface of the wind turbine blade, achieving quick installation and fixation of the device. The operation is simple and convenient for disassembly and assembly. The second rotating cap rotates the screw, which drives the square tube to extend and retract, positioning the guide hole at the drilling point. The first rotating cap drives the worm gear to rotate, which in turn drives the connecting tube to rotate through the meshing worm wheel, making the guide hole on the guide head perpendicular to the drilling point. The sliding L-shaped bracket brings the guide head into contact with the drilling surface, with the drilling point on the central axis of the guide hole. The first fixing bolt is then tightened to fix the L-shaped bracket to the end of the square tube. This simple operation facilitates the positioning of the drilling position, guides the drilling bit, and prevents drilling deviation.

[0012] 2. In use, the guide head is fixedly connected to the side wall of the present invention by inserting the plug into the slot of the L-shaped bracket, and the second fixing bolt is threaded through the through hole of the L-shaped bracket to connect with the plug, thereby fixing the guide head. Conversely, it is convenient to remove the guide head from the L-shaped bracket and repeat the above steps to replace the guide head. Attached Figure Description
