[0002] Wind turbine blades are the core components of wind turbines that convert natural wind energy into electricity for wind turbines. They are also the primary basis for measuring the design and technical level of wind turbines. The Chinese wind turbine blade market has formed a diversified investment model with foreign-funded enterprises, private enterprises, research institutes, and listed companies.

[0003] For example, a Chinese patent discloses a connection structure between a wind turbine blade and a pitch bearing (e.g., patent number: CN213981054U). The right end of each stud screw extends to the right, passes through a flange and an O-ring, and then is threadedly connected to a pre-embedded bolt sleeve. The pitch bearing outer ring connecting bolt passes through the outer ring of the pitch bearing and is then threadedly connected to the wind rotor hub. The automatic bolt centering device includes a high-circular sleeve and a low-circular sleeve. The right end of the high-circular sleeve and the left end of the low-circular sleeve are spherically connected. The inner diameters of the high-circular sleeve and the low-circular sleeve are larger than the diameter of the stud screw. The left end of the stud screw extends to the left, passes through the low-circular sleeve and the high-circular sleeve, and then is threadedly connected to a nut, affixing the right end of the high-circular sleeve to the left end of the low-circular sleeve.

The adjustment component in the wind turbine blade in the device is a high-efficiency adaptive component, and the adjustment component in the device needs to be disassembled when it is under maintenance. The user presses the end of the L-shaped pull plate 13 downwards Since the installation through hole 23 of the fixing plate 22 has a large space, the L-shaped pull plate 13 can be pressed down. When the L-shaped pull plate 13 is pressed down, the triangular block 12 at its upper end will move out of the installation through hole 23 of the fixing plate 22. At this time, the user pulls the L-shaped pull plate 13 to move the L-shaped pull plate 13 in the L-shaped slot 15 of the fixing block 14, so that the L-shaped pull plate 13 and the triangular block 12 can be separated from the fixing plate 22. At this time, the cover 21 and the pitch assembly housing 11 are separated by The T-shaped round rod 18 is rotatably connected, so the cover 21 can be rotated, so that the cover 21 can be flipped to the bottom of the pitch assembly housing 11, and then the interior of the pitch assembly housing 11 is completely emptied, which is convenient for the user to inspect and repair the adjustment gears inside it. In addition, the device is provided with a circular sealing film 19 on the pitch assembly housing 11, which can maintain a seal between the pitch assembly housing 11 and the cover 21 to prevent gaps from appearing between the pitch assembly housing 11 and the cover 21 and being penetrated by rainwater.

[0026] A T-shaped circular groove 24 is provided on the cover 21, and the T-shaped round rod 18 is rotatably installed in the T-shaped circular groove 24 provided on the cover 21.

This structure that is easy to disassemble and install makes the device more convenient to operate, saving maintenance time and cost. The new device maintains a seal between the pitch assembly housing 11 and the cover 21 by providing a circular sealing film 19 between the pitch assembly housing 11 and the cover 21, thereby avoiding gaps between the pitch assembly housing 11 and the cover 21, which are penetrated by rainwater, effectively improving the sealing inside the device, and better preventing dust, moisture, etc. from entering the interior of the adjustment component, affecting its normal operation and life.

[0027] Working principle:

[0028] In the first step, the adjustment component in the wind turbine blade in the device is a high-efficiency adaptive component, and the adjustment component in the device needs to be disassembled when it is inspected and repaired. The user presses down the end of the L-shaped pull plate 13. Since the installation through hole 23 opened in the fixed plate 22 has a large space, the L-shaped pull plate 13 can be pressed down. When the L-shaped pull plate 13 is pressed down, the triangular block 12 at its upper end will be moved out of the installation through hole 23 opened in the fixed plate 22. At this time, the user pulls the L-shaped pull plate 13 to move the L-shaped pull plate 13 in the L-shaped slot 15 opened in the fixed block 14, so that the L-shaped pull plate 13 can be And the triangular block 12 is separated from the fixing plate 22. At this time, the cover 21 and the pitch assembly housing 11 are rotatably connected by the T-shaped round rod 18, so the cover 21 can be rotated to allow the cover 21 to be flipped to the bottom of the pitch assembly housing 11, and then the interior of the pitch assembly housing 11 is completely vacant, which is convenient for the user to inspect and repair the adjustment gears inside it. In addition, the device is provided with a circular sealing rubber sheet 19 on the pitch assembly housing 11, which can maintain a seal between the pitch assembly housing 11 and the cover 21 to avoid gaps between the pitch assembly housing 11 and the cover 21, which are penetrated by rainwater.

[0029] In the second step, the present invention connects the cover 21 in the device with the pitch assembly housing 11 through a quick disassembly and assembly mechanism, thereby improving the efficiency of maintenance personnel in repairing components such as adjustment gears, and this structure that is easy to disassemble and install makes the device more convenient to operate, saving maintenance time and cost. The present invention maintains a seal between the pitch assembly housing 11 and the cover 21 by setting a circular sealing film 19 between the pitch assembly housing 11 and the cover 21, avoiding the formation of gaps between the pitch assembly housing 11 and the cover 21 and the penetration of rainwater, effectively improving the sealing inside the device, and better preventing dust, moisture, etc. from entering the interior of the adjustment component and affecting its normal operation and life.
