[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. In recent years, wind power has developed rapidly in emerging markets. With the support of national policies and tight energy supply, China's wind power, especially wind power equipment manufacturing industry, has also risen rapidly and has become the most active place for wind power in the world. Since wind power belongs to the category of new energy, there is still a big gap in cost and technology compared with traditional thermal power and hydropower. Therefore, the rapid development of wind power requires strong support from national policies.
[0003] The patent specification with announcement number CN217572574U discloses a pre-inspection and positioning device for wind turbine blades, including an operating frame, a mounting plate is installed on one side of the top of the operating frame, a slide groove is opened at the center position of the surface of the mounting plate, a wind turbine blade is installed at the center position of the outer wall of one side of the mounting plate, and an opening is provided at one end of the wind turbine blade. The utility model has a reasonable structure. The positioning mechanism is provided to place the wind turbine blades that need to be pre-inspected between two groups of placement tables, so that the two groups of placement tables clamp and position the outer wall of the wind turbine blade. The positioning mechanism has the effect of adjusting the clamping, and the inner wall of one end of the wind turbine blade can be clamped and fixed, thereby achieving the positioning effect, avoiding the unstable positioning of the wind turbine blade during pre-inspection, which affects the accuracy of pre-inspection, and effectively improves the stability of the pre-inspection and positioning device of the wind turbine blade.
[0004] However, in the implementation of relevant technologies, it was found that the above-designed wind turbine blade pre-inspection and positioning device has the following problems: in the prior art, the blades are clamped and positioned by placing a table and other components, but the structural length and local width of the blades themselves are different, and the clamping of a single end is unstable, and even gaps or looseness may occur during the clamping process, resulting in unstable clamping and positioning. In view of this, a wind turbine blade pre-inspection and positioning device is provided to overcome the above-mentioned defects. Utility Model Content

At the same time, outside the meshing area of the worm and the worm gear, there are threaded textures to facilitate threaded connection with the limiting block, so that when rotating, the limiting block can drive the clamping plate to adjust the width, which is suitable for blades of different widths.
[0008] As a further description of the above technical solution: a sliding structure is formed between the limit block and the support block, and the limit block is threadedly connected to the worm.

The power output end of the hydraulic rod is connected to a downward pressure block.

After the support rod passes through the carrier frame and the supporting plate, the threaded head and the connecting sleeve are threadedly connected, so that the clamping mechanism can be limited and fixed to avoid shaking when supporting the blades.
[0011] As a further description of the above technical solution: the fixing mechanism also includes a support plate, which is fixedly installed on the bottom end of the supporting plate, and the four corners of the bottom of the supporting plate are provided with universal wheels. The support plate is embedded with an electromagnet on the top end facing the carrier frame, and the universal wheel is used to facilitate the movement and adjustment of the clamping mechanism. When the position is determined, the electromagnet is energized to perform magnetic adsorption with the permanent magnet at the bottom end of the carrier frame to further improve stability.
[0012] As a further description of the above technical solution: the support rod passes through the interior of the supporting plate, and the support rod is fixedly connected to the connecting sleeve through a threaded head. The threaded connection between the threaded head and the connecting sleeve facilitates disassembly and assembly of the support rod, and facilitates adjustment of the position of the clamping mechanism.
[0013] As a further description of the above technical solution: a micro-roller is installed on the outer wall of the supporting plate facing the carrier, and a slide groove is opened on the carrier corresponding to the position of the micro-roller. The micro-roller supports the supporting plate to slide along the slide groove, thereby improving the smoothness of the clamping mechanism to adjust the position.
[0014] The utility model has the following beneficial effects:
[0015] The utility model designs a wind turbine blade pre-inspection and positioning device. A transmission part is driven by a motor, and the worm gear of the transmission part pushes the worm, so that the limit block passes through the support block, and the clamping width of the clamping plate is adjusted. It is suitable for blades of different widths. At the same time, the hydraulic rod pushes the pressing block to further fix the blades. A group of carrier frames is provided with a group of clamping mechanisms. According to the length of the blades, multiple carrier frames are fixedly connected by bolts to improve applicability.
[0016] The utility model designs a wind turbine blade pre-inspection positioning device. After the clamping mechanism is adjusted to a position along a limit groove through a supporting plate, a support rod is inserted through the supporting frame and the supporting plate, and is fixed by a threaded connection of a threaded head and a connecting sleeve, thereby improving the stability of the clamping mechanism. In cooperation with the electromagnet on the supporting plate, the permanent magnet at the bottom end of the supporting frame is magnetically adsorbed, thereby further improving the stability.
