Description

Technical Field

[0001] This utility model belongs to the field of wind turbine blade transportation, specifically relating to a combined connection structure of a wind turbine blade tip support. Background Technology

[0002] With the development of the wind power industry, offshore wind turbines are becoming increasingly larger, with wind turbine blades becoming larger and longer. This poses a significant challenge to the maritime transport of these blades. Currently, transport supports are commonly used to secure wind turbine blades to the deck of cargo ships. These transport supports consist of blade root supports and blade tip supports. The blade root supports are used to support and secure the root portion of the wind turbine blade, while the blade tip supports are typically located at the tip third of the blade to support and secure the other end of the blade.

[0003] In the aforementioned maritime transport, it is preferred to arrange multiple wind turbine blades closely together to maximize the use of deck space. Their blade tip supports also need to be arranged together. Before this invention, blade tip supports that are close to each other would shake and collide, posing a potential hazard. In addition to welding adjacent blade tip supports together, there is an urgent need for another convenient and quick combination connection method. Utility Model Content

[0004] In view of the above, this utility model provides a combined connection structure for wind turbine blade tip supports, which can conveniently and quickly combine adjacent blade tip supports together.

[0005] A combined connection structure for a wind turbine blade tip support is provided, comprising a connecting frame, a first positioning hole plate, a left tip support, a second positioning hole plate, a right tip support, a third positioning hole plate, a positioning rod, a first connecting plate, a second connecting plate, a third connecting plate, and a fourth connecting plate.

[0006] At least two first positioning hole plates are fixedly connected to the center of the connecting frame. A corresponding number of second positioning hole plates are fixedly connected to the left tip bracket, and a corresponding number of third positioning hole plates are fixedly connected to the right tip bracket. The first positioning hole plates, the corresponding second positioning hole plates, and the corresponding third positioning hole plates are located on the same straight line. A positioning rod is set to pass through the first positioning hole plate, the corresponding second positioning hole plate, and the corresponding third positioning hole plate simultaneously. In this way, after the positioning rod is used for positioning and docking, the left tip bracket, the right tip bracket, and the connecting frame can maintain a relative position, which facilitates connection in the following form.

[0007] A first connecting plate is fixed at each of the four corners of one side of the connecting frame, and a second connecting plate is fixed at each of the four corners of the other side of the connecting frame. Pin holes are provided on the first and second connecting plates respectively.

[0008] A third connecting plate is fixed at each of the four corners of the connecting end face of the left tip bracket, and a fourth connecting plate is fixed at each of the four corners of the connecting end face of the right tip bracket. Pin holes are also provided on the third and fourth connecting plates respectively.

[0009] The first connecting plate of the connecting frame corresponds one-to-one with the third connecting plate of the left tip bracket, and the first connecting plate and the corresponding third connecting plate are connected by a pin.

[0010] The second connecting plate of the connecting frame corresponds one-to-one with the fourth connecting plate of the right tip bracket, and the second connecting plate and the corresponding fourth connecting plate are connected by a pin.

[0011] Furthermore, threads are provided on the sides of both ends of the positioning rod. After the positioning rod passes through the first positioning hole plate, the corresponding second positioning hole plate, and the corresponding third positioning hole plate, nuts are screwed on both ends of the positioning rod for locking. In other words, in addition to the docking and positioning function, the positioning rod can also strengthen the connection, making the connection between the left tip bracket, the middle connecting frame, and the right tip bracket more reliable and stable.

[0012] Through the above technical solutions, this utility model has at least the following beneficial effects:
