Description

Technical Field

[0001] This utility model relates to the field of positioning mechanism technology, specifically to a positioning mechanism for fiberglass cloth layup on wind turbine blade shell. Background Technology

[0002] Wind turbine blades are the core components of wind turbines that capture wind energy. Their design, materials, and manufacturing processes directly determine the power generation efficiency, reliability, and lifespan of the wind turbine. When the wind blows over the wind turbine blades, the blades generate lift through aerodynamic design, which drives the hub and main shaft to rotate, and finally converts mechanical energy into electrical energy through the generator.

[0003] After the wind turbine blades are manufactured, fiberglass cloth is usually laid on their surface. Its purpose is to provide the blade shell with key properties such as structural strength, rigidity and fatigue resistance through the high strength and directionality of the fibers, while balancing the need for lightweighting. During the laying process, multiple layers of fiberglass cloth need to be laid on the surface of the blade shell. The two sides of the fiberglass cloth are placed over the two ends of the wind turbine blade shell, and then the workers smooth the fiberglass cloth on the blade surface to facilitate the laying of the next layer of fiberglass cloth.

[0004] When smoothing the fiberglass cloth, multiple workers are usually required to press and support the contact points between the fiberglass cloth and the edge of the wind turbine blade on both sides to prevent the fiberglass cloth at both ends from slipping when smoothing the inner surface. Since manual support is quite laborious, a fiberglass cloth laying positioning mechanism for wind turbine blade shell is proposed. Utility Model Content

[0005] This utility model proposes a fiberglass cloth laying and positioning mechanism for wind turbine blade shells, which solves the problem in the prior art that when laying fiberglass cloth on wind turbine blades, the fiberglass cloth at both ends of the wind turbine blades needs to be manually held to prevent it from slipping, which is quite laborious.

[0006] The technical solution of this utility model is as follows:

[0007] A fiberglass cloth laying positioning mechanism for wind turbine blade shell includes a movable plate, a positioning plate, a connecting plate, and a pressing rod. The bottom end of the movable plate is equipped with several casters. The positioning plate is mounted on the movable plate via a height adjustment assembly and is used to position and press the fiberglass cloth at both ends of the wind turbine blade. The connecting plate is mounted on the height adjustment assembly. Several pressing rods are provided and are mounted on the connecting plate via a rotation assembly.

[0008] Furthermore, the height adjustment assembly includes a support cover, a reciprocating screw, a first motor, and a sliding assembly. Two support covers are fixedly installed on the top of the moving plate. The reciprocating screw is rotatably installed in one of the support covers, and a matching crescent-shaped slider is installed on the reciprocating screw. The first motor is installed in one of the support covers, and the output end of the first motor is coaxially connected to the reciprocating screw. The sliding assembly is disposed in the other support cover.

[0009] Furthermore, the sliding assembly includes a sliding rod and a sliding block. The sliding rod is fixedly installed inside another support cover, the sliding block is slidably installed on the sliding rod, and the connecting plate is fixedly installed between the sliding block and the crescent-shaped slider.

[0010] Furthermore, the rotating assembly includes a mounting plate, a rotating shaft, and a drive assembly. Two mounting plates are fixedly mounted on the top of the connecting plate, the rotating shaft is rotatably mounted between the two mounting plates, and a plurality of pressing rods are fixedly mounted on the rotating shaft. The drive assembly is disposed on the connecting plate.

[0011] Furthermore, the drive assembly includes a second motor, a drive gear ring, and a drive gear. The second motor is mounted on the side of the connecting plate, the drive gear ring is fixedly mounted on the rotating shaft, the drive gear is coaxially connected to the output end of the second motor, and the drive gear ring meshes with the drive gear.

[0012] To further protect the meshing of the drive gear ring and the drive gear, a protective cover is detachably installed on the connecting plate, and both the drive gear ring and the drive gear are located inside the protective cover.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, when positioning and pressing the fiberglass cloth, the movable plate can be moved to the side of the wind turbine blade, and the positioning plate can be moved down by the height adjustment component, so as to attach the positioning plate to both ends of the wind turbine blade on which the fiberglass cloth is laid, thereby pressing and positioning the fiberglass cloth at both ends of the wind turbine blade to prevent slippage.

[0015] 2. In this utility model, after the positioning plate is pressed down, several pressing rods can be rotated again by the rotating component, so that the bottom end of the pressing rods contacts and presses other parts of the fiberglass cloth, pressing the fiberglass cloth and the wind turbine blade together, thereby further preventing the fiberglass cloth from sliding down when the staff smooths it out.

[0016] In summary, this device, through the cooperation of the moving plate, positioning plate, connecting plate and pressing rod, can press the fiberglass cloth at the contact points between the two ends of the wind turbine blade when the worker smooths the inside of the wind turbine blade, preventing it from slipping, and it does not require manual support, thus saving labor.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] like Figures 1-4 As shown, this embodiment proposes a fiberglass cloth laying positioning mechanism for wind turbine blade shell, including a moving plate 1, a positioning plate 3, a connecting plate 4, and a pressing rod 5. The bottom end of the moving plate 1 is equipped with several casters 2. The positioning plate 3 is set on the moving plate 1 through a height adjustment component and is used to position and press the fiberglass cloth at both ends of the wind turbine blade. The connecting plate 4 is set on the height adjustment component. Several pressing rods 5 are provided and are set on the connecting plate 4 through a rotation component.

[0025] like Figure 2 and Figure 4As shown, when positioning and pressing the fiberglass cloth, the device is first moved to the side of the wind turbine blade by the moving plate 1 and locked by the self-locking function of the caster wheel 2. Then, the positioning plate 3 is moved down by the height adjustment component to contact the two ends of the wind turbine blade, thereby positioning and pressing the fiberglass cloth. The height adjustment component includes a support cover 6, a reciprocating screw 7, a first motor 9 and a sliding component. Two support covers 6 are fixedly installed on the top of the moving plate 1. The reciprocating screw 7 is rotatably installed in one of the support covers 6 and a matching crescent slider 8 is installed on the reciprocating screw 7. The first motor 9 is installed in one of the support covers 6 and the output end of the first motor 9 is coaxially connected to the reciprocating screw 7. The sliding component is set in the other support cover 6. The sliding component includes a sliding rod 10 and a sliding block 11. The sliding rod 10 is fixedly installed in the other support cover 6 and the sliding block 11 is slidably installed on the sliding rod 10. The connecting plate 4 is fixedly installed between the sliding block 11 and the crescent slider 8.

[0026] Specifically, the first motor 9 is started, and the output end of the first motor 9 drives the reciprocating screw 7 to rotate inside the support cover 6, thereby driving the crescent slider 8 to adjust its height on the reciprocating screw 7. Under the drive of the connecting plate 4, the sliding block 11 moves synchronously on the sliding plate. It should be noted that the crescent slider 8 is mounted on the reciprocating screw 7 through a reciprocating sleeve, which is a known technology. Then, the positioning plate 3 is driven to move down. Because the wind turbine blade is arc-shaped, the shape of the positioning plate 3 can fit with both ends of the wind turbine blade and can press the fiberglass cloth onto the wind turbine blade. The length can also be the same as or slightly longer than the length of the wind turbine blade.

[0027] like Figure 3 As shown, during downward movement, the rotating assembly can be activated to rotate several downward pressure rods 5, thereby enabling the downward pressure rods 5 to move downward and contact the surface of the wind turbine blade, thus further pressing them down. The rotating assembly includes a mounting plate 12, a rotating shaft 13, and a drive assembly. Two mounting plates 12 are fixedly installed on the top of the connecting plate 4, and the rotating shaft 13 is rotatably installed between the two mounting plates 12. Several downward pressure rods 5 are fixedly installed on the rotating shaft 13. The drive assembly is set on the connecting plate 4 and includes a second motor 14, a drive gear ring 15, and a drive gear 16. The second motor 14 is installed on the side of the connecting plate 4, the drive gear ring 15 is fixedly installed on the rotating shaft 13, and the drive gear 16 is coaxially connected to the output end of the second motor 14, and the drive gear ring 15 meshes with the drive gear 16.

[0028] Specifically, the second motor 14 is started, and the output end of the second motor 14 drives the drive gear 16 to rotate. The drive gear 16 drives the drive gear ring 15, which meshes with it, to rotate. The drive gear ring 15 then drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives several pressure rods 5 to rotate, thereby adjusting the direction of the pressure rods 5 so that the bottom end of the pressure rods 5 faces down. When moving down, they can contact and press the fiberglass cloth onto the surface of the wind turbine blade. Because the connecting plate 4 is detachably equipped with a protective cover 17, and the drive gear ring 15 and the drive gear 16 are both located inside the protective cover 17, the meshing of the drive gear ring 15 and the drive gear 16 can be protected. When pressing is not required, the pressure rods 5 can rotate in the opposite direction to rotate to a horizontal position.

[0029] Working principle: When positioning and pressing the fiberglass cloth, the first motor 9 is started first. The output end of the first motor 9 drives the reciprocating screw 7 to rotate inside the support cover 6, thereby driving the crescent slider 8 to adjust its height on the reciprocating screw 7. Under the drive of the connecting plate 4, the sliding block 11 moves synchronously on the sliding plate. At this time, the second motor 14 is started synchronously. The output end of the second motor 14 drives the drive gear 16 to rotate. The drive gear 16 drives the drive gear ring 15 that meshes with it to rotate. The drive gear ring 15 drives the rotating shaft 13 to rotate. The rotating shaft 13 drives several pressing rods 5 to rotate, thereby adjusting the direction of the pressing rods 5 so that the bottom end of the pressing rods 5 faces down. When moving down, it can contact and press the fiberglass cloth on the surface of the wind turbine blade. At this time, the fiberglass cloth at both ends of the wind turbine blade can be pressed and positioned, and the staff can smooth it inside the wind turbine blade.

[0030] It should be added that the reciprocating screw 7 is equipped with a telescopic protective sleeve to protect it, and a portable generator can be installed on the equipment to supply power to the first motor 9 and the second motor 14.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
