Embodiment Construction

[0062] In the following, four embodiments of the present invention will be described in detail by taking a 5MW horizontal axis wind turbine as an example in conjunction with the accompanying drawings.

[0063] Figure 7 It is an isometric view of Embodiment 1 of the present invention——"V" type semi-submersible foundation, Figure 8 It is an isometric view of embodiment 1 of the present invention—a mobile ballast leveling control device in a "V" type semi-submersible foundation. The three-column semi-submersible offshore wind turbine foundation in Embodiment 1 includes three vertical columns (4) and (5) that are not collinearly arranged, and the total height of the columns is about 30 meters to 40 meters.

[0064] The top of the main column (4) is connected with the tower tube (8) of the wind generator, and the fan also includes key components such as the nacelle (9) and blades (10). The underwater bottom of the main column (4) is respectively connected to the peripheral two ...

Abstract

The invention provides a movable ballast leveling control device for a floating-type draught fan. Tilting and motion response of the floating-type draught fan can be restrained. The movable ballast leveling control device comprises a movable ballast, a sliding rail, a limiting support, a leveling control server and the like. The movable ballast is provided with a power part, a brake and a locking system and can receive signals in real time to slide, brake and lock on the rail. The sliding rail is arranged according to the basic layout and an available space of the floating-type draught fan and is provided with a sliding rail body, a hinge, a lead screw and the like needed by moving of the ballast. The limiting support is arranged at the end of the rail, so that the ballast device is prevented from sliding out of the rail; and a ballast power auxiliary device is placed. The leveling control server can be installed in a basic deck or a draught fan tower tube, and according to the velocity magnitude and direction monitoring data of wind, waves and streams, a real-time active control instruction is sent to the movable ballast device.

Description

technical field [0001] The invention belongs to the field of wind power generation and relates to an offshore floating wind turbine foundation. Background technique [0002] The gradual depletion of land wind resources has shifted human attention to a new direction of clean energy—offshore wind power. Offshore wind power has the advantages of high wind speed, large power, stable operation, and is suitable for large-scale development. Moreover, the southeast coastal areas with the most abundant offshore wind energy resources are adjacent to economically developed areas with large demand for electricity, which can realize nearby consumption of electricity and reduce transportation costs. , great potential for development. It is estimated that the energy efficiency of offshore wind energy resources is 20% to 40% higher than that of onshore wind power. [0003] For deep-water marine environments with a water depth greater than 40 meters, the basic economy of floating wind turb...
