Platform floating type wind driven generator provided with suction caissons and used for sea surface of deep sea

Abstract

The invention provides a platform floating type wind driven generator provided with suction caissons and used for the sea surface of a deep sea and belongs to the technical field of sea wind power generation. The platform floating type wind driven generator comprises a wind driven generator body, a tower, a platform mechanism with tension legs and the suction caissons, wherein the tower, the platform mechanism and the suction caisson are sequentially arranged at the bottom of the wind driven generator body. The platform mechanism comprises a deck platform, a floating body and a mooring mechanism, and the mooring mechanism comprises a suction caisson and a tying tendon for connecting the suction caisson and the floating body. The platform floating type wind driven generator overcomes the defects that an offshore wind driven generator in the prior art is high in basic installation cost, high in noise pollution, long in installation period and low in applicable water depth, and the installed single wind driven generator is low in power generation power. The platform floating type wind driven generator has the advantages that basic installation of the wind driven generator of a whole system is convenient and rapid, installation cost is low, installation noise pollution is low, the platform floating type wind driven generator cannot damage the seabed and can be installed in a deepwater area which is further from the shore, and the installed single wind driven generator is higher in power generation power.

Description

Technical field [0001] The invention relates to a device in the technical field of offshore floating wind power generation, in particular to a platform floating wind motor with a suction caisson used in the deep sea. Background technique [0002] The early offshore mono-pile fixed wind turbines were expensive to manufacture, and the construction process of inserting the mono-pile deep into the seabed was complicated. It was limited to use when the water depth was less than 20 meters. Under normal circumstances, it could only generate 3.5 megawatts of electricity. In recent years, offshore wind power development has gradually developed from shallow water areas to deep water areas. The Massachusetts Institute of Technology and the National Renewable Laboratory of the United States first proposed the concept of deep-water platform-based floating wind turbines. Platform-based floating wind turbines are on land. Upper processing and segmented installation, large closing on the sea lev...

Problems solved by technology

[0007] Aiming at the above-mentioned deficiencies in the prior art, the present invention proposes a platform floating wind motor with a suction caisson for deep sea surface, which overcomes the high installation cost, high noise pollution and long installation period of the offshore wind motor base in the prior art , Applicable to the shallow water depth, the installed single wind turbine power generation is small, the installation of the wind turbine foundation with the whole system is convenient, the installation cost is low, the installation noise pollution is low, it will not cause damage to the seabed, and it can be installed farther from the shore The deep water area, the single installed wind turbine has the advantages of greater power generation, etc.
