Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of ocean engineering equipment, especially to a self -adaptation clamping structure of fan blade installation equipment. BACKGROUND

[0002] With the rapid development of marine new energy development, the offshore wind power development range gradually expands from shallow sea to deep sea. Offshore wind turbine is a device for converting wind energy into electric energy, which is usually composed of fan blades, cabin, tower and foundation. Among them, the foundation is used to support the whole fan to ensure its stability, and the tower is connected with the foundation and the cabin to support the cabin and the fan blade. The cabin is located at the top of the tower and contains a generator, a gearbox and a control system, which is responsible for converting wind energy into electric energy. The fan blade is fixed on the cabin and rotates by wind energy, and the kinetic energy of the fan blade is converted into electric energy through a transmission device.

[0003] The hoisting of offshore wind turbine blades is one of the key links of the installation of the entire wind turbine. With the continuous increase of single machine capacity of wind turbine, the size of the blade of wind turbine is also gradually increasing. In wind power generation, a blade clamping device is needed to facilitate the installation and fixation of the blade. However, due to the large length and weight of the blade and its complex shape, combined with the uncertainty of the offshore environment, the blade needs to be placed and transported by a specific blade support device before hoisting, and the blade hoisting clamping device needs to be replaced for hoisting operation. To solve the above problems, a self-adaptive integrated device technology is proposed in Chinese patent CN115215192B to solve the problem of multiple specific tools required for blade storage and assembly. The inter-blade working condition self-adaptive integrated device automatically adjusts the blade from a horizontal position to a vertical position, and then simultaneously hoists the blade. When the blade installation is completed, the hook of the crane is slightly loosened, the inter-blade working condition self-adaptive integrated device and the blade root storage hoisting device are separated at a certain distance below the device, and then the device is moved along the long axis of the blade to finally separate from the blade. However, this scheme still has the following problems: the blade clamping structure is formed by the upper and lower contour plates, and the clamping structure is relatively fixed, which is difficult to adapt to different sizes and shapes of fan blades, and has low adaptability. Especially during installation, if the clamping structure cannot adapt to the shape of the blade, it may cause indentation or deformation on the surface of the blade. Moreover, the blade is only clamped at the root, which is prone to displacement or loosening during transportation and hoisting, and the clamping stability needs to be improved.
