Description
Technical field
The present invention relates to Offshore Wind Power Generation Technology field, more particularly to a kind of marine wind electric field many blower fan bases waterborne
Plinth 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, with large-scale development condition
And Commercial Prospect, countries in the world build wind power plant energetically, and 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 and deep-sea wind-powered electricity generation by residing marine site position
.Shallow sea wind power 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
Normally operation has the high control requirement of comparison to foundation uneven settlement and flange face inclination angle to machine.Offshore wind turbine foundation type selecting should
Consider the influence in terms of the depth of water, sea bed geological conditions, offshore distance, marine environmental conditions and construction level.For suitable
For the fixed blower foundation of shallow sea wind power, pile foundation is mainly used at present, pile foundation has high capacity, settle it is small and
Uniformly, the features such as anti-seismic performance is good, can preferably bear xial feed, horizontal loading and the vibration produced by fan operation
And dynamic action, extensive use in marine, land, shoal area wind power plant and harbour engineering at home and abroad, there is maturation
Experience of design and construction procedure.
For the pile foundation in marine wind electric field, mainly include single-pile foundation and many pile foundations, the general cost of single pile is relative
It is relatively low, it is current main application pattern, and many pile foundations have more preferable rigidity and security, the adaptation to geology and the depth of water
Property is wider.With the progressively increasing developed rapidly with wind power generating set single-machine capacity of wind power generation industry, Oversea wind hair
The development of electric field will be increasingly faster, and scale is also incrementally increased.At the same time, also corresponding offshore wind farm supporting construction is set
Meter, installation, construction and security maintenance propose higher technical requirements.Many pile foundations are in the depth of water relatively deep, complicated geology, unit
Wider application is had in capacity big shallow sea wind power.
Many pile foundations should angularly consider in design from mode, structural strength, deformation and construction, it is ensured that complete machine is certainly
Vibration frequency avoids wind wheel driving frequency and the notable scope of wave frequencies, in the presence of wind, wave, stream, in many pile foundation steel constructions
Stress distribution it is uniform, limit stress is smaller, it is smaller to deform, while the design on basis should be easy to construction and installation.But it is existing
The structure of marine many pile foundations is usually relatively complex, and causes to build and difficulty of construction is big, and resist the ultimate load of wind, wave etc.
Ability is poor, and torsional rigidity is weaker, uses poor reliability.
The content of the invention
Based on this, the present invention is necessary to provide a kind of marine wind electric field many blower foundations waterborne and Wind turbines, resistance
