Embodiment Construction

[0028] According to the design requirements, design and manufacture the semi-submersible foundation buoyancy box 2 at the bottom of the column, the lattice truss support beam 3, the support beam buoyancy box 4, and the seabed mooring facilities 5. Assemble the generator set on the beach when the sea tide is low, the generator set is in a floating state after the sea tide ebbs, use a tugboat to tow the generator set to the designated sea area, open the sea bottom valve 9, inject seawater into the ballast tank 7, adjust with ballast water The levelness of the generating set makes the whole conjoined foundation submerged underwater, and then anchors the generating set with the seabed mooring facility 5 . If the generating set needs to be moved again, the mooring is released, the ballast water is discharged, the towing cable is attached, and the generating set is dragged by the tugboat to a new designated sea area.

Abstract

The invention discloses foundation of an offshore wind generation facility, particularly a semi-submersible type steel structure mounting foundation platform of offshore wind driven generators which is capable of moving on the sea, is simple in manufacturing and low in cost. The semi-submersible anchoring type offshore wind generating set with an integrated pedestal is characterized in that: seven wind driven generators are mounted on a regular hexagonal semi-submersible type steel structure integrated foundation platform; the seven wind driven generators are mounted on semi-submersible foundation buoyant boxes 2 with cylindrical bottoms at the six vertexes and the centre of the regular hexagonal semi-submersible steel structure integrated foundation platform respectively; the overall generating set floats on the sea; and the bottom of the overall generating set is fixed by a submarine anchoring facility 5. As the overall integrated foundation platform is submerged in water, the water plane of the generating set is very small, as a result, the generating set has excellent stability, instantaneous buoyancy caused by sea level fluctuation changes a little, and no matter the generating set in a towing state in normal weather or in an anchoring state in extreme weather, both the rigidity of the stability of the generating set can satisfy design demands; and the size of the regular hexagon is determined by the minimum separation required according to the mounting specification of the offshore wind driven generators.

Description

[technical field] [0001] The invention relates to a foundation for offshore wind power generation facilities, in particular to a steel structure foundation for mooring, movable and connected bases. [Background technique] [0002] At present, the columns of the wind power generators located at sea are all fixed on the foundation of the seabed. The construction of this kind of foundation has high requirements on the seabed environmental conditions, the construction is difficult, the construction period is long, the cost is high, and permanent industrial waste will be generated after being discarded. [Content of the invention] [0003] The purpose of the present invention is to change the basic mode of the current offshore wind power generator, change the seabed fixed type to a semi-submersible mooring type, and provide a combined type for the offshore wind power generator, floating on the sea surface, mooring, movable, and able to meet the needs of the sea. The steel struct...
