[0001] The utility model relates to the technical field of wind turbine blades, and specifically provides an auxiliary tool for laying the rear edge UD of a blunt trailing edge type wind turbine blade SS surface. Background Art

[0002] Wind energy is a clean and renewable energy source. Wind power generation is widely used in coastal islands, grassland pastoral areas, mountainous areas, plateau areas and other areas with water shortage, fuel shortage or inconvenient transportation. It can save a lot of non-renewable energy consumption. The use of wind power generation according to local conditions has been highly valued by countries around the world. As the most basic and critical component of wind turbines, the performance and quality of wind turbine blades are the decisive factors to ensure the normal and stable operation of wind turbines.

[0003] As the global wind power market shifts to wind energy development at low wind speeds and offshore wind farms, blades continue to grow, especially blunt-end-type wind turbine blades, which are getting longer and longer. The quality reliability and stability requirements for mass-produced blades are also getting higher and higher. Large wind turbine blades usually include SS face shells, PS face shells, webs, small webs at the trailing edge, main beams and trailing edge UDs. The SS face trailing edge UD is the main load-bearing part of the blade structure. It is composed of unidirectional fiber reinforced fabrics, which can effectively improve the swing array strength of the blades and is an important component of the blades. In the production and manufacturing process of wind turbine blades, the trailing edge UD needs to be laid. Since the existing laying methods are mostly manual laying, the unidirectional fiber fabric of the trailing edge UD is prone to wrinkles, which makes it difficult to ensure the quality of maintenance when wrinkles are found after the blades are formed. At the same time, the labor intensity of workers is high and the work efficiency is low when the manual laying method is used.

[0004] Therefore, how to design a wind turbine blade SS surface trailing edge UD laying auxiliary tooling that is highly efficient, low-strength and suitable for blunt-end-edge wind turbine blades is a problem that needs to be solved urgently. Utility Model Content

[0007] Furthermore, the UD roller is located on a side close to the push handle, and the cloth rolling roller and the UD roller are evenly arranged at the bottom end of the storage box and located on a side away from the push handle.

[0008] Furthermore, the accommodating groove is a U-shaped groove structure; the storage box includes a side wall 1 and a side wall 2 which are perpendicular to each other, the push handle is connected to the side wall 1 on one side of the storage box, and the accommodating grooves are evenly opened on the side wall 2 on both sides.

[0009] Furthermore, the two ends of the sleeve rod are respectively slidably connected to the accommodating grooves on the two side walls, and the two ends of the sleeve rod are provided with limit blocks clamped on the outer end surfaces of the two side walls.

[0010] Furthermore, the length of the sleeve rod is greater than the length of the sleeve in the UD sleeve, and the outer diameter of the sleeve rod is smaller than the outer diameter of the sleeve in the UD sleeve. After the UD sleeve is sleeved on the sleeve rod, the UD sleeve is entirely located inside the two side walls.

[0011] Furthermore, the distance between the bottom end of the accommodating groove and the lower end surface of the second side wall is smaller than the radius of the sleeve in the UD sleeve. During the laying process, there is always no gap between the UD sleeve and the mold platform.

[0023] In the following, reference will be made to the Figure 1-3 Describe the embodiment of the utility model. In the following description, the same modules are represented by the same reference numerals. In the case of the same reference numerals, their names and functions are also the same. Therefore, the detailed description thereof will not be repeated.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following Figure 1-3 It should be understood that the specific embodiments described herein are only used to explain the present invention and do not constitute a limitation on the present invention.

[0025] A blunt trailing edge type wind turbine blade SS surface trailing edge UD laying auxiliary tooling, such as Figure 1-Figure 3 As shown, it includes a frame-type storage box 1 and a push handle 2 connected to one side end of the storage box 1. A accommodating groove 3 is opened on the storage box 1, and the accommodating groove 3 is a U-shaped groove structure. A sleeve rod 4 is slidably connected in the accommodating groove 3. The UD sleeve is sleeved on the sleeve rod 4. The sleeve rod 4 can drive the UD sleeve to slide up and down in the accommodating groove 3. The UD sleeve is located on the inner side of the frame of the storage box 1. The storage box 1 includes a side wall 1 7 and a side wall 2 8 that are perpendicular to each other. The push handle 2 is connected to the side wall 1 7 on one side of the storage box 1. The push handle 2 is welded to the side wall 1 7 or is integrally formed with the side wall 7. The push handle 2 is a telescopic structure, which is convenient for improving versatility.

[0026] The bottom end of the storage box 1 is connected with a cloth rolling roller 5 and a UD roller 6. When laying, the UD sleeve is flattened on the lower end of the UD roller 6. The UD roller 6 is located on the side close to the push handle 2. The cloth rolling roller 5 and the UD roller 6 are evenly arranged at the bottom end of the storage box 1 and are located on the side away from the push handle 2. A connecting hole 11 is opened at the bottom end of the side wall 8. The cloth rolling roller 5 and the UD roller 6 are rotatably connected in the connecting hole 11, and the UD roller 6 is connected to the connecting hole 11 through a bearing.

[0027] The accommodating grooves 3 are evenly opened on the side walls 8 on both sides, and the two ends of the sleeve rod 4 are respectively slidably connected to the accommodating grooves 3 on the side walls 8 on both sides. The two ends of the sleeve rod 4 are provided with limit blocks 9 clamped on the outer end surfaces of the side walls 8. The limit blocks 9 prevent the sleeve rod 4 from slipping out of the accommodating groove 3. The accommodating groove 3 is vertically opened in the middle of the side walls 8, which is convenient for uniform force, accommodating more UD sleeves, and facilitating the unwinding operation during the UD sleeve laying process.

[0028] The length of the sleeve rod 4 is greater than the length of the sleeve 10 in the UD sleeve, and the outer diameter of the sleeve rod 4 is smaller than the outer diameter of the sleeve 10 in the UD sleeve. After the UD sleeve is sleeved on the sleeve rod 4, the UD sleeve is located as a whole in the side walls 8 on both sides, and the distance H between the bottom end of the accommodating groove 3 and the lower end surface of the side wall 8 is smaller than the radius of the sleeve 10 in the UD sleeve. During the laying process, there is always no gap between the UD sleeve and the mold platform.

[0029] When in use, first put the UD sleeve on the sleeve rod 4, and install the sleeve rod 4 into the accommodating groove 3. At this time, there are more sleeves (usually fiber cloth) on the sleeve 10, and the lower end of the sleeve is placed on the table of the mold. The sleeve above the sleeve 10 is rolled up and wrapped around the lower end of the UD roller 6. The initial end of the sleeve is facing the push handle 2, that is, in the direction of B. The push handle 2 is pushed by hand to push the storage box 1 in the direction of A. At this time, the sleeve is rolled up until all the sleeves are laid out. During the laying process, the sleeve rod 4 slides down in the accommodating groove 3. When the sleeve is laid out, the sleeve rod 4 slides down to the lowest end of the accommodating groove 3, and the lower end of the sleeve rod 4 is located on the table of the mold.

[0030] Turn the storage box 1 around at the B end, load a new roll of sleeve material onto the sleeve material rod 4, install the sleeve material rod 4 into the accommodating groove 3, unroll the sleeve material above the sleeve 10 and wrap it around the lower end of the UD roller 6, with the initial end of the sleeve material facing the push handle 2, that is, in the direction of A. Push the push handle 2 by hand to push the storage box 1 in the direction of B. At this time, the sleeve material is unrolled and the second layer is laid. During the laying process, the rolling roller 5 flattens the previously laid sleeve material to prevent wrinkles until all the sleeve material is laid, and then returns to the B end.

[0031] Repeat the above operation, from end A to end B, and then from end B to end A, repeating the process of laying multiple layers until the laying is completed.

[0032] During use, the cloth rolling roller 5 and the UD sleeve itself are used as "rollers", and the push handle 4 is manually held to push the entire tooling forward. The UD sleeve can be smoothly and quickly "unrolled" during the rolling process, and the cloth rolling roller 5 can achieve the effect of flattening the cloth of the previous layer during the laying of the second, third, and Nth layers, further ensuring the flatness of the UD laying at the rear edge. The cloth rolling roller 5 can be made of sponge, metal, and other materials.

[0033] By taking advantage of the "cylindrical" property of the UD sleeve and using the UD sleeve as a "roller", fast and smooth "unwinding" and laying of the UD fiberglass cloth can be achieved. Combined with the cloth rolling rollers 5 before and after the tooling, the UD laid by the tooling can be further flattened, which can greatly reduce the risk of UD wrinkles formed by manual laying and reduce labor time to a certain extent.

[0034] Although the embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and cannot be understood as limiting the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.

[0035] The above specific implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
