Abstract

The invention relates to a wind power generator for driving multiple generators by a magnetic suspension vertical wind blade rotating cage. More than sixteen vertically placed wind blades are arranged outside the rotating cage; the wind blades are made of protruded composite material; the outer parts of the wind blades are convex, and the inner parts of the wind blades are concave; a plurality of windshield bars are arranged in the inner concave surfaces; a large inner gear arranged in the rotating cage drives gears on eight generators to rotate and generate; the rotating cage is suspended by magnetic suspension; the friction resistance is small; only the gears and the generators are used and are produced by domestic material; and the power can achieve more than 12MW.

Description

The vertical fan blade rotating cage of magnetic suspension drives the wind-driven generator of many generators

Technical field

The invention belongs to generator and wind-driven generator field.

Background technique

The wind-driven generator of our times advanced level is three fan blade horizontal axis, and power is in 3 megawatts, and it is unusual difficulty that power strengthens, and complex equipments, and amount of maintenance is big, and efficient is low.Present vertical axis aerogenerator, blade is little, has only a generator on the axle, and power is very little, is fit to family, highway lamp stand usefulness.

Summary of the invention

Vertical fan blade rotating cage of the present invention is by top rotary table, lower rotary table, vertically prop up the cylinder type rotating cage of the rigidity that materials such as lacing wire, brace process.On the fan blade mounting plate of the outer rim of top rotary table, lower rotary table, tens or tens fan blades are installed vertically.Top rotary table, lower rotary table are installed the maglev utmost point of non-electric neodymium iron boron respectively, and another utmost point is installed on the column on the magnetic suspension support, and the installed inside of top rotary table or lower rotary table has large-scale internal gear.

By the composite material fan blade that pultrude process is processed, it is shaped as the streamlined of evagination indent hollow.Outer convex surface is smooth, and inner concave has many muscle that keep out the wind longitudinally for mouth.This fan blade can be accepted octahedral and the wind comes from, and the concave surface of the blowing leaf of the wind comes from of face produces power with the wind, and when this fan blade turns over 180 when spending, the convex surface of fan blade facings the wind, although resistance is arranged, because the smooth resistance of convex surface is very little, need not adjusts fan blade angle and just can receive very big power.If add the fan blade reclining apparatus, facing the wind with leptoprosopy when then fan blade forwards the windward side to, just better.

The column generator bay is equipped with the vertical permanent magnet generator that many (as: 8,12) have clutch and brake.Generator is fixed on the fixed plate at generator bay top, on the generator input shaft of lengthening gear is housed, each gear all with rotating cage on the engagement of large-scale internal gear.

Fan blade on the mounted rotating cage is accepted the wind comes from and is driven the rotating cage rotation, and internal gear on the rotating cage and rotating cage are with changeing, and the internal gear meshed gears is high speed rotating also, generator for electricity generation output.Only connect one, two generators during startup, breeze start-up is convenient in other generator clutches, adds generator after having changeed again gradually.All brakes start when needs are shut down, and rotating cage also just stops operating.

Select the permanent magnet generator of multipole number for use, the generating frequency when improving slow speed, all efficiently operations in whole vertical fan blade rotating cage range of revolution; Generating efficiency is high; The gear that large-scale internal gear drives on the generator just increases revolution, thus can be without equipments such as speed increasers, simplified apparatus.

To make upper and lower two rotating cages when selecting birotor generator for use, above rotating cage bottom dress internal gear, below the top of rotating cage internal gear is installed, drive two rotors running generatings of generator respectively, can send the electric power of several times.

Adorn the just high wind in good utilisation high-altitude more of two or two above said apparatus on the column, an available generator bay is adorned upper and lower two-layer generator, can conveniently manage, keep in repair.

The invention has the beneficial effects as follows:

Fan blade is installed in the rotating cage outer rim; Moment is big on the axle, and fan blade is wide to reach 2 meters, and length can reach 60 meters; The blowing area of a concave panel just reaches 120 square metres; Fan blade quantity can be installed ten several or tens, can make the above wind-driven generator of 10 megawatts, and 10 megawatts are that horizontal axis wind-driven generator can't be realized.The generator techniques of existing technology 1.5 megawatts is ripe, adorns the generator of 8 1.5 megawatts in the generator bay of the present invention, just can make the wind-driven generator of 12 megawatts.It is big that interior external gear teeth is counted difference, increases rotating speed and simplify power generating equipment, and power generating equipment is simple, and running is reliable, and amount of maintenance is little, and floor space is little, and the face of collecting folk songs is big, wind energy utilization is high.
