Marine wind electric field more blower foundations waterborne and Wind turbines
Technical field
Offshore Wind Power Generation Technology field is the utility model is related to, more particularly to a kind of marine wind electric field more wind waterborne
Machine basis and Wind turbines.
Background technology
Wind energy is a kind of renewable green energy resource of cleaning, and development efficiency is high, good economy performance, has large-scale development condition
And wind power plant is built in Commercial Prospect, countries in the world energetically, wind generating technology is also developed rapidly.Oversea wind
Aboundresources, bigger than land wind-force generated energy, marine wind electric field is divided into shallow sea wind power field and deep-sea wind-powered electricity generation by residing marine site position
.Shallow sea wind power field is applied to the marine site of the depth of water within 50m, using fixed base form.
Offshore wind turbine foundation is subjected to the load that the towering blower fan in top is brought, and will resistance wave load, wind lotus
The collective effect of multiple loads such as load, water flow load, ship collision load, its suffered horizontal force and tilting moment are larger, and wind
Machine normal operation has the high control requirement of comparison to foundation uneven settlement and flange face inclination angle.Offshore wind turbine foundation type selecting should
Consider the influence of the depth of water, sea bed geological conditions, offshore distance, marine environmental conditions and construction level etc..For suitable
Main at present use pile foundation for the fixed blower foundation of shallow sea wind power field, pile foundation has high capacity, settle it is small and
