Abstract
The utility model relates to a foundation structure of a single pile type offshore wind driven generator. The utility model aims at providing a foundation structure of a single pile type offshore wind driven generator, which can be applicable to offshore area, is applicable to soft soil foundation and areas being easy to be washed, and can effectively resist the corrosivity of seawater, is applicable to single-machine unit being 0.75-5MW, and has cheap cost, reliability, and convenient construction. The technical scheme for solving the problems is as follows: for the foundation structure of the single pile type offshore wind driven generator, the lower end of the foundation structure is provided with a single large-diameter steel tube pile fixed with the offshore wind driven generation foundation, the upper end of the steel tube pile is fixed with the lower end of a connecting cylinder by grouting, and the upper end of the connecting cylinder is connected with a stepped drum by a flange. The foundation structure of the single pile type offshore wind driven generator can be used for offshore wind power plant engineering.
Description
Technical field
The utility model relates to a kind of single pile formula offshore wind generating fondational structure, is applicable to Oversea wind power generation field engineering.
Background technique
In China, the wind-power electricity generation industry is an emerging industry.Last century, the eighties rose, and China's introduction of foreign technology is Construction of Wind farm at home progressively, after 2000, because country encourages the development and utilization to renewable energy sources, domestic wind-power electricity generation industry was developed rapidly.
Up to the present, China in the Inner Mongol, Xinjiang, Hebei and the coastal region in east China built up large quantities of land wind energy turbine set.But extensive development along with the wind-powered electricity generation industry, the land resources anxiety, day by day manifest with the problem such as shield of giving of local other industries, and China has very long shore line, its marine zone is contained abundant wind energy resources, in recent years, offshore wind farm is developed fast.
Because the particularity of marine physical environment, common land construction plant and method of construction can not be used, and the wind driven generator base structure of land routine can not be used for the sea.Be used for marine wind driven generator base and will solve a series of problems such as anti-tidewater, soft foundation, corrosion protection, lack the construction experiences of marine wind electric field at present, still do not find the fondational structure processing form of a kind of cheapness, reliable, easy construction.
The model utility content
The technical problems to be solved in the utility model is: provide a kind of and can be applicable to marine greater coasting area, be applicable to soft soil foundation and the zone that is subject to wash away, can effectively resist corrosive properly, be applicable to that single-machine capacity is 0.75～5MW, and offshore wind generating fondational structure cheap, reliable, easy construction.
The technological scheme that the utility model adopted is: single pile formula offshore wind generating fondational structure, this fondational structure has lower end and the fixing single large diameter steel pipe pile of offshore wind generating basic foundation, the steel pipe pile upper end is fixed by grouting and connecting cylinder lower end, and the connecting cylinder upper end is connected with the tower tube by flange.
Described large diameter steel pipe pile inside is equipped with the adjusting bolt of leveling connecting cylinder; The large diameter steel pipe pile external diameter is 3000～6000mm, and wall thickness is 24～80mm.
Described connecting cylinder external diameter is 2700～6300mm, and wall thickness is 24～80mm, rises floor height in extreme high water mark, and inside is equipped with the blower fan inner platform, and the outside is equipped with the blower fan outer platform.
Be provided with cat ladder from foundation surface to the blower fan outer platform in the outside of steel pipe pile and connecting cylinder.
The beneficial effects of the utility model are: (1) this fondational structure adopts single large diameter steel pipe pile foundation, easy construction, and the engineering time is short, only needs a heavy pile, and required construction equipment, operating expenses are few; (2) adopt single large diameter steel pipe pile foundation, material economy, cost is low, relative three formulas or many formula steel structure bases, material economy is obvious; (3) single large diameter pile structure section is little, can reduce the effect of unrestrained pressure and ocean current to greatest extent, can be applicable to the variable domain of sea bed and the zone that is subject to wash away well;
(4) adopt connecting cylinder to link to each other with large diameter steel pipe pile, accurately leveling of connecting cylinder has solved the demanding problem of tower tube installation precision; (5) adopt grouting to be connected between steel pipe pile and linkage section, easy construction, and can adapt to the site operation error; (6) floor height of rising of connecting cylinder designs in extreme high water mark, prevents that effectively seawater from entering in the tower tube and wind turbine equipment is produced corrosion.
