Description
Technical field
The invention belongs to technical field of wind power generation, relate to a kind of many perpendicular wheel connection wheel wind wheel generators; Be particularly related to a kind of tower multistage perpendicular wheel connection wheel wind wheel generator.
Background technique
The wind resource of China is very abundant, and the annual mean wind speeds in most areas are all at per second more than 5 meters, particularly northeast, northwest, southwest plateau and offshore islands, and mean wind velocity is bigger; Some places, the 1 year time more than 1/3rd all was the strong wind sky.In these areas, the development wind-power electricity generation is up-and-coming.Wind is one of energy that does not have public hazards.And it is inexhaustible.For lack of water, short bunker and ungetable offshore islands, pastoral area, grassland, mountain area and area, plateau, utilize wind-power electricity generation with suiting measures to local conditions, very suitable, be well worth doing.According to estimates, the wind resource that can be used to generate electricity on the earth has 10,000,000,000 kilowatts approximately, almost is 10 times of present whole world hydroelectric power amount.The present energy that obtained of the annual coal combustion in the whole world, have only wind-force in 1 year the energy that provides 1/3rd.Therefore, all take much count of both at home and abroad utilizing wind-force to generate electricity, tap a new source of energy.
Present domestic and international large-scale unit megawatt wind-driven generator, the main shaft of wind wheel all is parallel transverse axis, the blade of wind wheel is suspended on the parallel transverse axis.Wind wheel is utilizing aspect the wind resource, can only utilize the wind-force of a direction, can not multi-facetedly utilize wind resource timely and effectively, more can not adapt to the wind speed and direction that changes all the time all the time.Present high-power wind-driven generator: 60 meters to 80 meters of the general radiuses of wind wheel blade, directly through 120 meters and 160 meters, wind generator tower is the highest 180 meters.Wind wheel blade resists aspects such as folding, anti-twist ability in compressive strength, and demand material standard-required is very high.Material material: 1, want light.2, to resist high pressure, anti-folding, anti-twist intensity good.Guarantee that wind wheel blade is stressed when 30 meters/S wind speed, the crack of wrecking can not appear in blade.3, wind speed surpass 25 meters/when S checked car, whole wind wheel can not rotate, blade also will change pitch by motor, and blade side is facingd the wind, and also needs to have the high strength and the ability of anti-hurricane.4, leaf production will use senior high-strength carbon fibre or other to have the materials processing of light-high-strength, and every fan blade oar nearly weighs about 15 tons, and fan blade oar cost is high, accounts for more than 65% of wind power plant expense.When 117 meters of wind-power electricity generation tower heights, required steel reach 240 tons, and 160 meters tower heights need 360 tons of steel, and accessory nearly weighs more than 130 ton, about 500 tons of gross weight, single wind-power electricity generation manufacture cost height.The wind speed that the blower fan of wind-power electricity generation is changed all the time restricts, and running speed is fluctuated can not uniform rotation, and faults such as broken teeth often appear in gear-box, are the tall orders of having a headache most in the wind power plant Maintenance and Repair.So this wind-driven generator structure complexity, the blower fan accessory is many, and the each side material requires standard very high, and Use Limitation is short, and difficulty, maintenance cost height are installed, overhauled to poor safety performance.So it is short complicated working life to plant wind-driven generator structure, the operating cost height, the big electricity price height of cost of electricity-generating is unfavorable for applying.
The development of the existing high-power parallel axes wind-driven generator of home and abroad unit has been arrived and has been difficult to progressive to some extent stage.Find through international search: the wind-powered electricity generation machine of 2 MW class is not also produced and is come into operation; The wind-powered electricity generation machine of 3 MW class is also in positive R﹠D process; Its main cause is that the length of fan blade and width effectively strengthen technical problem and can't solve.
