Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine blade transportation, in particular to a wind turbine blade transportation device. Background Art

[0002] Wind turbine blades are the core components of wind turbines that convert natural wind energy into electricity for wind turbines. They are also the main basis for measuring the design and technical level of wind turbines. In addition, wind turbine blades need to be transported using a vehicle-mounted transport device. The extra-long blades of large wind turbines are getting longer and longer. When the blades are loaded and transported horizontally, the tail of the blades is blocked by obstacles when the transport vehicle turns. At the same time, the blade length is too long, and the flexibility of the tail of the blade is getting greater and greater, which makes it extremely difficult to transport in complex areas. For example, the utility model patent number CN214998034U discloses a device for transporting wind turbine blades, including a blade root support device and a blade tip support device. The blade root support device includes a top crossbeam, a base, a first column, a second column, and an arc support plate. The top crossbeam is connected to the base through the first column and the second column, and the arc support plate is connected to the base. The blade tip support device includes a top crossbeam, a lower combined bracket and a base. The lower combined bracket is connected between the top crossbeam and the base. A combined support body is provided in the lower combined bracket. The combined support body is provided with an opening corresponding to the outer contour of the blade tip. This patent ensures that the blade has fixed support at both the root and the tip by providing devices for fixing the blade root and the blade tip respectively. However, the combined support body in the blade tip support device corresponds to the outer contour of the blade tip, so this device is only suitable for one or similar wind turbine blades. For the various specifications of wind turbine blades currently on the market, there are certain limitations. Therefore, it is necessary to develop a wind turbine blade transportation device to address the above defects. Utility Model Content
