Embodiment Construction

[0021] Such as figure 1 As shown, the invention discloses a multi-column floating Spar fan foundation, including a hard tank, a truss structure, and a ballast tank. The hard cabin includes a side column 1 , a central column 9 , and a reinforcing plate 10 . In this embodiment, the side column cabin 7 provides buoyancy, the reinforcement plate 10 connects the side column and the central column to improve the structural strength of the hard cabin, and the waterline surface cabin is provided with double-layer partitions 8 to increase the strength of the column.

[0022] In this embodiment, the truss structure is composed of 4 vertical support columns 6, 24 side beams 4, and 2 heave plates 5, and the heave plates have holes arranged in 3*3. The truss column 6 connects the side column 6 and the ballast tank 3, and the inclined beams and the multi-hole heave plate are vertically and evenly distributed on the column.

[0023] In this embodiment, one end of the mooring system is fixe...

Abstract

The invention discloses a multi-column spar-type floating fan platform. An existing spar-type fan foundation is mostly of a single-column truss-type structure and has high antidumping stability, but due to the single-column structure of the spar-type fan foundation, the spar-type fan foundation is liable to be affected by vortex-excited vibration, meanwhile, the number of compartments is small, sinking resistance is low, and buoyancy adjusting performance is poor. Aiming at the situation, the multi-column spar-type floating fan platform is optimized and improved, one-large and four-small combined vertical columns are used for replacing a single column, and the effect of vortex-excited vibration is avoided or reduced. Compartment division is conducted on the central vertical column, the side vertical columns and a ballast compartment, the buoyancy, the gravity and adjustment ability are provided, and damaged compartment stability is increased.

Description

technical field [0001] The invention relates to offshore wind power generation infrastructure, in particular to floating wind power generation in water depths of 50 to 100 m. Background technique [0002] With the shortage of land resources, the development of land wind energy, which requires a large area of ​​land, has been hindered. The ocean has a vast space and high wind energy density, so offshore wind energy has received great attention in recent years. According to the statistics of existing observation data, the total wind energy reserves that can be developed and utilized in my country are about 1 billion kilowatts, of which the wind energy reserves that can be developed and utilized in the offshore area are 750 million kilowatts, which is more than three times that of land wind energy resources, and the water depth is more than 30 meters Wind energy resources are more abundant. The basic planning of wind farms in areas with a water depth below 20m along the coast o...
