Problems solved by technology

Anti-rolling water tanks are mainly divided into two types: passive and active. Among them, the frequency range of the passive type is narrow, and there will be adverse consequences of increased roll outside the allowable frequency range; the active control type is mainly controlled by opening/closing valves, but the phase respons

Example Embodiment

[0065] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.

[0066] figure 1 It is a perspective view showing an offshore wind power generator according to an embodiment of the present disclosure. Such as figure 1 As shown, the offshore wind turbine mainly includes: a floating foundation 4; a plurality of mooring cables 5, one end is connected to the floating foundation 4, and the other end is anchored on the seabed; the tower 3 is installed on the floating foundation 4 and consists of the floating foundation 4. Support; wind turbine 2 and blade 1, installed on the top of the tower 3. The bottom end of the tower 3 can be connected to the floating foundation 4 through a tower supporting device. In the present disclosure, the tower supporting device is a supporting column 18 (which will be described in detail below) provided in the center of the floating foundation 4.

Abstract

The invention discloses a stabilizing device, a floating foundation and an offshore wind power generator. The stabilizing device comprises a U-shaped water chamber, wherein the U-shaped water chamber comprises a first hollow upright column, a second hollow upright column and a bottom buoyancy tank connected between the bottoms of the two upright columns, the first upright column and the second upright columns are communicated with the bottom buoyancy tank, and the top of the first upright column and the top of the second upright column are communicated through an air communication pipeline. The floating foundation is at least provided with a first upright column, a second upright column and a third upright column, and comprises at least one stabilizing device. The offshore wind power generator comprises the floating foundation, a mooring rope, a tower, vanes and a wind power generator set, wherein the mooring rope is connected with the outer edge of the floating foundation and is anchored to the seabed, the bottom end of the tower is arranged on the floating foundation, and the vanes and the wind power generator set are arranged on the top of the tower. By means of the stabilizing device, stabilizing of a floating fan can be simply and effectively achieved through a double-resonance principle.

Description

technical field [0001] The present disclosure relates to an offshore wind power generator, and more particularly, to an anti-rolling device and a floating foundation with the anti-rolling device. Background technique [0002] At present, in order to meet the needs of developing deep-sea wind farms, people have applied the deep-sea floating oil platform commonly used in the offshore oil industry to the wind power field, and successively developed single-pillar platforms (SPAR), semi-submersible platforms (Semi-submersible), tension Leg platform (TLP) floating fans and other composite floating fans. So far, three floating wind turbine projects have been built, such as figure 1 Shown are Hywind, Blue H and Windfloat respectively. Hywind was jointly developed by Statoil Hydro of Norway, Technip of France and Siemens of Germany, and was built in the North Sea near Norway in 2009. The basic concept adopted by Hywind is SPAR. The floating structure is a slender steel pipe about ...
