Description

Big-and-middle-sized wind-driven generator

Technical field

The utility model relates to a kind of new and renewable sources of energy generator, particularly a kind of big-and-middle-sized wind-driven generator.

Background technique

Oil and other fossil fuel environmental pollutions are very large and will use up very soon, must utilize renewable energy sources by Devoting Major Efforts To Developing, produce the electricity of cleaning with it.Now the big-and-middle-sized wind-driven generator of production and application is a lot of both at home and abroad, is almost a sample entirely, all has many problems: the one, and unreasonable structure, performance is lower; The 2nd, volume and weight is large, and tower is lusty, build not only large but also dark basis, and required investment is very large; The 3rd, the requirement wind speed is high, and the time that can reach is short, and the unit generated energy is few, adds that investment is large, and the repaying payment of interest time is long, causes the cost of generating very high; The 4th, difficult manufacturing, difficult transportation, difficulty are installed, difficulty is repaired; The 5th, working life is short, and is safe not.Therefore, present big-and-middle-sized wind-driven generator must improve.

Summary of the invention

The purpose of this utility model is the shortcoming of eliminating above-mentioned existence, and a kind of big-and-middle-sized wind-driven generator is provided, and makes inexhaustible cleaning, safe, cheap wind energy become electric energy.

In order to achieve the above object, technical measures of the present utility model are:

a kind of big-and-middle-sized wind-driven generator, it becomes perpendicular power to horizontal power, move very heavy generator on the basis that is put at the bottom of tower from the support tower top, wind wheel organization is arranged on support tower top by one for its rotating mechanism that rotates along horizontal plane, horizontal drive shaft one end of this wind wheel organization is for driving the wind wheel of its rotation, the other end is the wind direction rudder, horizontal drive shaft is arranged on rotating mechanism by two bearing supports, the medium position of horizontal drive shaft is equipped with large umbrella gear, be arranged on vertical drive shaft with the small umbrella gear of its engagement, vertical drive shaft is connected to the alternator shaft of downward-extension bottom being arranged on support tower.

Wind wheel is propeller type, and for catching more windy energy, the diameter of wind wheel can require to strengthen according to generator power, and the fan blade of wind wheel can increase to 6～9 by common 2～3, the wing of the similar helicopter of shape of fan blade, and the material of fan blade is carbon fiber.

Generator is permanent magnet generator, and the rotating shaft upper and lower end is protruding, and on it, spindle nose connects tightly by flange and vertical drive shaft, and lower spindle nose is installed the load-bearing bearing, and the load-bearing bearing is fixed on the basis of support tower bottom.Because the generating function is positioned on the basis of support tower bottom, its power can be selected arbitrarily, and wind-driven generator is made super-huge, large-scale, medium-sized and small-sized multiple grade.

Support tower is made with angle steel, and is network-like for up-small and down-big square, can be high or low, changeable, and its bottom is arranged on the basis that concrete or steel material make, and is equipped with the up and down working bin at the bottom of tower top and tower.

Being equipped with at the supporting tower top the circular traffic cycle made from angle bar, be slide rail above traffic cycle, and horizontal rotating shaft is fixed on slide rail by two groups of bearings, can box haul rotates 360 and spends, and is connected to the support tower top below traffic cycle.

The velocity ratio of large small umbrella gear is 1:3～8, and the wind direction rudder is Fishtail, is positioned on an end and traffic cycle limit of horizontal drive shaft.Controller is positioned on the wind wheel back, and recording anemometer and sensor are positioned on the supporting tower top, also are equipped with computer and motor in upper working bin.

Because very heavy generator can be moved on on basis at the bottom of tower by tower top, the intensity of tower can reduce, tower body suitably can be dwindled, the garden tubular that steel plate is made change into angle steel make network-like, reduce in a large number steel and weight, approximately can reduce 40%.

Because the supporting power of tower alleviates, be beneficial to and increase, and wind wheel is strengthened, increase fan blade, improve fan blade shape and the angle of attack, can catch more windy energy; By improving the kind of drive, can significantly increase the speed change multiple, improve generator speed, approximately can increase generated energy 20%.

Because generator can be placed on basis at the bottom of tower, be beneficial to and use high-power generator, improve the wind-driven generator grade.

This wind-driven generator has very large flexibility and adaptability, can make large-scale, medium-sized, small-sized, also can with by land, the sea, the place of great heat or severe cold.

Because tower body available angle steel is done, generator can be placed on basis at the bottom of tower, but simplified structure reduces manufacturing, transportation and installation difficulty in a large number, also is beneficial to the R and M maintenance, increase the service life, can do not blown down by strong wind, but about reduce cost 30% reduces cost per unit 50%, have very high economic benefit and social benefit, be beneficial to popularization.
