Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade storage fixtures, specifically to an adjustable trailing edge beam storage rack for wind turbine blades. Background Technology

[0002] Wind turbine blades are the core components of wind turbine generators, converting natural wind energy into electrical energy. They are a primary indicator of a wind turbine's design and technological level. The working principle of wind turbine blades is to utilize wind energy, generating mechanical energy through blade rotation, and ultimately converting that mechanical energy into electrical energy. The trailing edge sparsity is a crucial component of the blade, playing an indispensable role in enhancing its structural strength and stiffness, as well as extending its fatigue life.

[0003] Currently, most wind turbine blade forming processes use a trailing edge beam prefabrication process. The prefabricated trailing edge beam needs to be stored. The trailing edge beam of a wind turbine blade is a spatial curved surface with different heights and angles per meter of cross-section, and uneven thickness. If it is not stored properly, it will cause deformation and damage to the trailing edge beam. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an adjustable trailing edge beam storage rack for wind turbine blades, which can realize the shape-adjustable storage of trailing edge beams and avoid product quality defects caused by the storage rack not conforming to the shape during storage.

[0005] This utility model is achieved through the following technical solution:

[0006] An adjustable trailing edge beam storage rack for wind turbine blades includes a base plate with a column on the base plate. The column is fitted with multiple sets of positioning cylinders and connecting cylinders. The positioning cylinders are movably connected to the column, and the connecting cylinders are positioned above the positioning cylinders. A connecting plate is detachably connected to one side of each connecting cylinder. A conformal panel is rotatably connected to the end of the connecting plate away from the connecting cylinder. One end of the conformal panel is rotatably connected to the connecting plate, and an adjustment plate is detachably connected to the other end of the conformal panel. The end of the adjustment plate away from the conformal panel is movably connected to the connecting plate.

[0007] More preferably, each connecting cylinder has a mounting plate on one side, and the mounting plate is detachably connected to the connecting plate. The connecting plate includes a plate body and a mounting part, which is welded to the plate body. The mounting part has two circular holes, and the mounting plate has one circular hole and one arc-shaped waist hole. The circular hole one at the top of the mounting part is bolted to the circular hole two at the top of the mounting plate, and the circular hole one at the bottom of the mounting part is bolted to the arc-shaped waist hole at the bottom of the mounting plate.

[0008] More preferably, the connecting plate has bolt holes three on its body, and the adjusting plate has multiple bolt holes four. Bolts and nuts are used to movably connect the bolt holes three on the connecting plate to any one of the bolt holes four on the adjusting plate.

[0009] In a further preferred embodiment, the column is provided with several through bolt holes 1, and each positioning cylinder is provided with through bolt holes 2. Bolts and nuts are used to connect bolt holes 2 and any bolt hole 1 on the column, thereby movably connecting the positioning cylinder to the column.

[0010] More preferably, the bottom of the conformal panel is provided with a support plate for placing the trailing edge beam that supports the fan blades.

[0011] More preferably, the side of the conformal panel facing away from the adjustment plate is provided with a polyurethane pad for contacting the rear edge beam during storage.

[0012] More preferably, the base plate is provided with multiple fixing holes for fixing the storage rack to the ground by threaded connection, and multiple reinforcing ribs are evenly provided between the column and the base plate to enhance the firmness between the column and the base plate.

[0013] The beneficial effects of this utility model are:

[0014] This utility model discloses an adjustable trailing edge beam storage rack for wind turbine blades. During use, the height of the connecting plate and the conformal panel can be adjusted by fixing the positioning cylinder and the column. The tilt angle of the connecting plate and the conformal panel can be adjusted by adjusting the position of the bolts in the arc-shaped holes at the bottom of the mounting plate. The angle of the conformal panel can be adjusted by adjusting the fixing position of the plate and the connecting plate, ensuring that the polyurethane pad on the conformal panel fits snugly against the trailing edge beam, thus meeting the requirement for safe, conformal storage of the trailing edge beam. The purpose of using the polyurethane pad is to prevent hard contact between the storage rack body and the product during storage, avoiding damage to the trailing edge beam. This utility model's trailing edge beam storage rack improves the safety of trailing edge beam storage and avoids quality problems caused by the trailing edge beam not being stored conformally.

[0026] Please refer to Figure 1-5 An adjustable trailing edge beam storage rack for wind turbine blades includes a base plate 1 and a column 2. The column 2 is connected to the base plate 1. The base plate 1 has multiple fixing holes 3 for fixing the storage rack to the ground via threaded connections. Multiple reinforcing ribs 4 are evenly distributed between the column 2 and the base plate 1 to enhance the stability between the column 2 and the base plate 1. The column 2 has several through bolt holes 5. Multiple positioning cylinders 6 and connecting cylinders 7 are fitted on the column 2. The positioning cylinders 6 and connecting cylinders 7 correspond one-to-one. The connecting cylinder 7 is above the corresponding positioning cylinder 6. Preferably, three sets of positioning cylinders 6 and connecting cylinders 7 are arranged. Each positioning cylinder 6 has a through bolt hole 2 (not shown in the figure). The bolt hole 2 cooperates with the bolt hole 5 for the bolt to pass through. The bolt passes through the bolt hole 2 of the positioning cylinder 6 and any bolt hole 5 on the column 2 and is threadedly connected to a nut. The positioning cylinder 6 is fixed at different positions on the column 2 by bolts, thereby adjusting and positioning the height of the connecting cylinder 7 above the corresponding positioning cylinder 6.

[0027] Each connecting cylinder 7 has a mounting plate 8 on one side, and a connecting plate 9 is detachably connected to each mounting plate 8. A conforming panel 10 is rotatably connected to the end of the connecting plate 9 away from the mounting plate 8. One end of the conforming panel 10 is rotatably connected to the connecting plate 9, and an adjusting plate 11 is detachably connected to the other end of the conforming panel 10. At the same time, the end of the adjusting plate 11 away from the conforming panel 10 is movably connected to the connecting plate 9.

[0028] Preferably, the detachable connection between the connecting plate 9 and the mounting plate 8 is achieved by bolt connection. Specifically, the connecting plate 9 includes a plate body 12 and a mounting part 13. The mounting part 13 is welded to the plate body 12. The mounting part 13 is provided with two circular holes 14. The mounting plate 8 is provided with one circular hole (not shown in the figure) and one arc-shaped waist hole 15. One bolt passes through the circular hole 14 at the top of the mounting part 13 and the circular hole 2 at the top of the mounting plate 8 and is connected to a nut. Another bolt passes through the circular hole 14 at the bottom of the mounting part 13 and the arc-shaped waist hole 15 at the bottom of the mounting plate 8 and is connected to a nut. By adjusting the positions of the lower bolt and nut in the arc-shaped waist hole 15, the tilt angle of the connecting plate 9 can be adjusted.

[0029] Preferably, the movable connection between the adjusting plate 11 and the connecting plate 9 is a bolt connection. Specifically, the connecting plate 9 has bolt holes 16 on its body 12, and the adjusting plate 11 has multiple bolt holes 17. The bolt passes through the bolt holes 16 on the connecting plate 9 and any one of the bolt holes 17 on the adjusting plate 11 and is threaded to a nut. The bolts fix the connecting plate 9 and the adjusting plate 11 at different positions, thereby adjusting the tilt angle of the conformal panel 10 connected to the adjusting plate 11. During the adjustment of the tilt angle of the conformal panel 10, the bottom of the conformal panel 10 rotates with the connecting plate 9, and the top of the conformal panel 10 tilts left and right depending on the fixed position of the adjusting plate 11 and the connecting plate 9, thereby adjusting the tilt angle of the conformal panel 10.

[0030] Preferably, the bottom of the conformal panel 10 is provided with a support plate 18 for placing the trailing edge beam that supports the fan blades. The side of the conformal panel 10 facing away from the adjusting plate 11 is provided with a polyurethane pad (not shown in the figure) to prevent the storage rack from contacting the trailing edge beam during storage and to avoid damage to the trailing edge beam.

[0031] Preferably, the main body of the storage rack is made of a round tube with a diameter of 95 x 8 mm as the upright 2 of the storage rack. A conformal panel 10, consistent with the rear edge beam, is machined from a 6 mm steel plate, and polyurethane pads are attached to the conformal panel 10. At the same time, an adjustment plate 11 is machined from a 6 mm steel plate with a size of 300 x 30 mm, and four bolt holes 17 with a diameter of 18 mm are machined at 20 mm intervals on the adjustment plate 11 for adjusting the conformal panel 10.

[0032] The specific implementation process of this utility model is as follows: During the storage of the rear edge beam, the rear edge beam is first lifted, and then the fixing positions of the adjusting plate 11 and the connecting plate 9 are adjusted according to the angle of the rear edge beam. After the rear edge beam is placed on the conformal panel 10 of the storage rack, the bolt positions in the lower arc-shaped waist hole 15 of the connecting plate 9 and the mounting plate 8 are finely adjusted so that the polyurethane pad on the conformal panel 10 is completely in contact with the product surface, thus meeting the requirement of conformal and safe storage.
