Wind turbine blade securing system

This creation refers to a securing system, especially a securing system for the transport and storage of wind turbine blades.

Conventional land and sea wind turbine blade transportation and storage devices usually adopt two different structural components at the root and tail of the blade, and even another fixed structural support is provided in the center of the blade. The design is complicated and requires parts. There are many types, so it takes a lot of time and cost in the manufacturing and assembly process, and the assembly is also confusing.

In addition, the conventional structure mostly transports and stores a single-size blade, and usually does not consider whether the design can be adjusted according to different sizes of blades, so the structure needs to be re-cut and welded to be in accordance with the blade size, and the cost is required. Additional manpower, time and cost.

Therefore, this design is more complicated in designing and improving the structure of the conventional structure, and requires a large variety of parts. In the manufacturing and assembly process, it takes a lot of time and cost, and the assembly is also easy to be confused, and only the transportation and storage are single. The lack of size of the blade provides a wind turbine blade securing system with a simplified design, a single, common structural design, consistent specifications, not only convenient for production and assembly, but also more convenient to use. The base is designed with a detachable quick disassembly and assembly device, which can improve the utilization rate and operation efficiency, so it is not required for assembly. Spending too much time and cost, avoiding confusion in assembly, and adding a design that can be adjusted according to different blade sizes, without having to re-cut and weld to meet the blade size, so no additional cost is required. Manpower and cost, and the object arrangement is in the same direction of a row of roots, the next row of tails in the same direction, staggered, and can also save space for layout.

A wind turbine blade securing system of the present invention comprises a fixed frame group, which is formed by laminating at least one base frame; an adjusting rod having at least one adjusting hole obliquely crossing at each end of each of the at least one base frame And a support member connected to each of the at least one base frame; wherein the adjustment rod is connected to a blade root by the at least one adjustment hole.

The at least one base frame may be a quadrilateral or a polygon; the support member is made of a flexible material. The present invention may further comprise at least one fixing member or a pivoting member, the at least one fixing member may be a bolt, a nut or a locking pin, connecting the adjusting rod and the at least one base frame, and connecting the adjusting rod and the blade root The pivoting member is movably coupled to the adjusting rod and the at least one base frame such that the adjusting rod is movable according to the size of the blade, and the pivoting member can be a rotating shaft or a pivot.

The at least one fixing member or the pivoting member is obliquely slanted to the two ends of each of the at least one base frame, and the adjusting rod is aligned with the at least one locking hole of the blade root with the at least one adjusting hole The adjusting rod is connected with the blade root to form a plurality of supporting points, so that the blade root can be fixed, avoiding rotation and sliding, and uniformly dispersing the weight of the blade root and the root of the at least one base frame. Avoid that the blade root weight is concentrated in the middle of the adjustment rod to cause deformation. In addition, the adjusting rod has the at least one adjusting hole, and the position of the locking can be adjusted according to different blade sizes, and the cutting is not required to be re-cut and welded to meet the blade size, so that no additional labor and cost are required. The tail of the blade is supported by the support member of flexible material, and can also be adjusted and tensioned according to the shape of the tail of the blade to avoid shaking and sliding.

According to the requirement, a plurality of the fixed frame groups can be arranged and arranged according to the requirements, and the plurality of sets of wind turbine blades can be placed adjacent to the fixed frame group by the support members, so that the objects are discharged in a row with the roots in the same direction. The next row of tails are in the same direction and staggered, which also saves space for layout.

The present invention forms the fixed frame group by stacking and combining the at least one basic frame of the same structure, adopts a simplified design, uses a single and common structural design to make a composition, and has the same specifications, which is not only convenient for production and assembly, but also can be used more. convenient. In addition, the base can be designed with a detachable quick disassembly and assembly device, which can improve the utilization rate and the operation efficiency, so that the assembly does not require too much time and cost, and the confusion of assembly can be avoided.
