DD209878A5 - WIND POWER PLANT FOR HIGH PERFORMANCE - Google Patents

Abstract

The wind turbine for high performance solves the technical problems of stability, the vortex losses in the air, the force attack at the longest lever arm despite the wind speed superior circulation path speed and the capture of highest wind speeds without significant brake or friction losses. The heavy-duty high-performance dynamo is the focus of the entire system. The windstow in the individual propellant wings causes the wind-cutting edges of the following propulsion wings to rotate in the counter-vortex of an air-disperse space. The attack of the wind on the Windradflaeche is uniformly increased by the inside acting pure Schubueber over a fleeting Wegdruecken the middle Treibfluegel to the outside even accelerating Duesen Rueckstrahlantriebe, so that the entire Windradflaeche is used with leafless overlapping Treibfluegeln. The attack of the highest wind accelerations is resiliently converted into an increased wind outflow of the circulation and absorbed by an elastic electronic power take-off.

High power wind turbine Field of application of the invention

The invention relates to a plant for the conversion of wind energy into electrical energy "and is particularly suitable for Hegionen with steady winds, but can exploit all wind strengths.

Characteristic of the known technical solutions

There are known a variety of wind turbines, which are constructed according to a variety of principles. All together have the disadvantage that they do not work at all wind strengths with a good degree of utilization.

Object of the invention

The aim of the invention is to eliminate the lack of poor utilization of all wind forces.

Explanation of the essence of the invention

This object is achieved by a wind turbine whose windmill is designed with many vorsegelartig co-operating wings in a correspondingly stable construction.

The wind vane fixedly connected to the upper part of the system controls the wind turbine steady so that the wind hits it perpendicular, it circulates by means of the propellant wings and flows behind him in a direction opposite to the circulation. It is the peculiarity of the invention to make this through-flow effective as a rotary drive for the entire wind turbine surface.

Although the Umlaufweggeschwindigkeit the wing is so large that it exceeds the normal wind speeds and runs it in a sense, it is just there seeks an equivalent driving effect of wind power because the wind works there at the longest lever arm. There are therefore also from the inside to the outside circular-sector widening Treibflügelflachen largest «The high number of overlapping propulsion blades ensures that the entire windage surface is used for circulation acceleration of the wind turbine.

By the vorsegelartige attachment of the propellant wings, each of them runs in the air-diluted space, which gives him in front of the own Windanschnittskante the front of him propelling wings. In the hollow surface of the wind flow accumulates sideways, so that immediately adjacent to this sideways dammed wind flow creates an air-thinned room, in which the next propellant wing bursts. Firmly connected to the bottom plate of the upper part is the large upper

Power dynamo machine, which counteracts at this point of .Plastplastigkeit the system by being attached to the center of gravity of the entire system. The magnetic or armature windings of the dynamo are broken down so that individual parts thereof automatically increase or decrease with the increase or decrease in the number of revolutions corresponding to the wind speed and with such automatic increase or decrease of power take-off the wind turbine raging in case of storm or stagnation in doldrums spare · The dynamo should therefore be designed so high in its performance, that it is not overloaded even at peak demands highest wind forces »

Made of light metal windmill has as many spokes, as it can accommodate rotatable on them on the outer ring of bath, vorsegelartig complementary propellant wings.

The spokes of the large wind turbine are connected between the inner carrier wheel and the outer bathing ring in Badius distance of about two meters firmly with other bath wreaths, which share the spokes in corresponding part spokes on which corresponding Teiltreibflügel on both sides in the bathing wreaths in the manner are stored, that a circular sector-shaped four-cornered nose slides on the wing edge in a circular sector-shaped recess of the inner edge of the bathing ring and is held in this recess by a bracing spring after the windlass.

To adjust the effect of wind on the Umlaufweggeschwindigkeit the different wheelbases of the wind turbine, the more shared drive _v wings are so twisted in itself

and recorded in this connection as the basic position of their holding springs, that the angle formed by the wind vane parts and the wind turbine on the inner carrier wheel with 45 ° is the largest and evenly decreases from there to a fast parallel position to the wind turbine ·

The overlapping Teibflügel come so close to each other in their almost parallel position to the wind turbine that the wind accumulation in the preceding rotating propellant flow through a nozzle-like constriction between the ireibflügein and thereby must be effective as an additional accelerating Sückstrahlantrieb for the wind turbine ·

The propellant blades are pushed out of their basic setting to the wind turbine by sudden squalls against the force of their retaining springs, so that an increased outflow arises until the acceleration of the windmill has caused the same increased outflow and the tensioned springs with the transition of wind acceleration in die.erhöhte wind speed return the opened propeller to the spring and propellant-blade default settings ·

As in the case of the Honnef turbine, it is not the rotation of the axle but that of the outer wheel rim of the wind turbine that determines the height of the line of force and thus the power of the dynamo, since the outer ring itself does not itself participate in the function of the dynamo engine but its axis drives directly mechanically ·

The use of highest wind forces for the peak generation of electrical energy is achieved by their immediate release for consumption, in particular for storage for periods of doldrums. This storage takes place by the delivery to electrolysers for hydrogen production for a hydrogen dynamo drive or by the delivery to an immersion heater heating of Moltopren water tanks for the heating of a steam turbodynamo ·

The plant consists of the bottom base 1 and the rotatable upper part 2 with the wind turbine 3 "It is preferably suitable for installation on the sea coast of the North German Plain, on the wooded heights of the low mountain ranges or on the free plateaus of the Alps for community supply of villages or neighborhoods ,

The platform 5 cles bottom part 1 of the plant is so high that it just protrudes over the tops of the forest · Thus, the treetops with their inclination can deflect the wind up and hit the bottom of the windmill fully, so that the lower part of the The forest should therefore also remain under the platform 5 & ^Q s lower part of the plant or allowed to regrow.

Above the rotatable base plate 6, the tower 8 of the upper part 2 of the plant, which is streamlined parallel to the axis of the wind turbine 3, rises · In its massive uppermost part, the wind turbine axle 9 is secured in ball or plastic bearings 10 against any tilting.

The outwardly widening propellant wings 11 are bird-wing-like provided with a thick Windanschnittskante 12, behind the bead of wind on the slightly convex wing surface slides along and generates a thrust in the direction of rotation of the wind turbine.

The bulges of the wind-ledge edge 12 of the wings are hollow and rotatably support with this cavity the spokes 13 of the windmill as their axles These voids are foamed and therefore silent The wings are supported on the spoke-like axles in plastic * and thus maintenance-free ,

The example, three-part drive vanes are so twisted in itself and are held in this use as a basic position of their retaining springs that the angle formed by the wing surfaces and the / indradfläche on the inner carrier wheel with 45 ° is greatest and from there to the outside The wind velocity of the wind speed of the wind wheel can be adjusted evenly up to a nearly parallel position.

The orbital path acceleration growing from the inside out corresponds to an acceleration of the wind speed that increases from the inside to the outside. This growth begins at the wind speed slowed to the extent of the thrust on the inner carrier wheel, increases as a reduction of this deceleration by the sliding along the hollow surface of the middle wing and goes outward in an acceleration of the wind speed itself.

The overlapping propulsion blades come out towards each other in their parallel position to the wind turbine so close, ^r that the windstorm in the preceding propellant flow through a nozzle-like constriction between the propellant blades and thus must be effective as an additional accelerating Bückstrahlantrieb for the wind turbine , When sailing hard on the wind, such a jet effect is introduced by means of Lat ~. Introduced into the sails perpendicular to the leech. aspired to. ,

Thus, the driving effect of the recirculating path speed growing from the inside to the outside increases correspondingly from the pure thrust force for the inner propellant wings to the continuous driving speed.

nudge, which also pushes away the faster moving propulsion blades sideways like inclined planes, up to even the fastest outer propelling wings still accelerating jet reflex drives. Thus, the wind impinging on the wind turbine surface is converted from its inflow over the conical inner carrier wheel to the acceleration of still the relatively fastest outer wheel rim in rotational speed of the wind turbine, which must be absorbed by a correspondingly high electric power.

It is therefore important that an immediate mechanical reduction in the amount of damage on the outer wheel rim in the simplest form can be transferred to the working dimension of the force line section in the dynamo engine 14 and be able to dissipate this as electrical power.

The constant load of the rotational momentum of the wind turbine slows its ability to adapt to sudden gusts by orbital acceleration and thus allow the wind to flow out more appropriately.

Sudden storms push the propulsion blades against the force of their retaining springs out of their basic position to the wind turbine - in the hurricane vertical position to the wind turbine - in order to procure an increased outflow until the orbital acceleration of the wind turbine produces the same increased outflow Has. With the passage of wind acceleration into the increased wind speed, the taut peders gradually return the opened propelling blades back to the spring and propulsion wing basic settings. This allows the wind turbine to intercept hurricane gusts elastically.

This inertia corresponds to the handing over of the sheet of a sail. The inertia of the boat braked by the water corresponds to the braking effect of the wind turbine rotation by the force line cut in the dynamo machine generating the continuous electric power.

The high power line section of the high-performance dynamo machine 14 also ensures with its drive shaft when switched on with all windings that the wind turbine can be braked in calm. · This Äbbremsung can still be reinforced by the fact that on both sides of the dynamo drive shaft from the platform of the lower part of the plant a heavy brake pad is raised with a worm thread and pressed against the outer rim of the wind wheel.

The wind vane is provided with an unlocking and latching swivel, so they sander as a safeguard against a sudden horizontal pivoting of the upper part of the system in the wind direction down and brought down to the platform of the lower part can be lashed »

Further determination options of the movable system should be unnecessary, since the system works completely maintenance-free and can run for years without human intervention.

Sin excessive Windraddurchmesser no longer has a decisive effect on the increase in power, since the nozzle-like acceleration of the wind on the outer rim is limited »Sine further increase in performance must then be achieved by increasing the number of wind turbines.

The most extensive use of the full surface area of the wind requires a high toughness and breaking strength of the material of the entire system, which can certainly be ensured with a windmill diameter of 16 meters. Otherwise, it is worthwhile to distribute the energy supply to several similar wind turbines.

The high performance of the system is thus characterized by the fact that it uses the entire wind they hit by the design of Y / indradfläche by the system leaves the wings not in braking vortices, but in the air-diluted rooms uew run without them outwardly to the winds This is achieved by Z * B. facing the Noah wind energy plant

1) about 80 instead of 6 rotor blades use the thrust of the wind,

2) the outwardly widening wings let the main thrust of the wind also act on the most favorable lever arm,

3) the individual wings do not circulate in any vertebrae caused by the wings revolving before them, but in an air-diluted tree created by their flow guidance and

A-) the rotation of the wings in itself outwardly leads up to their near-touch and thus increases the wind speed with favorable lever arm to the nozzle-return jet drives.

From this fact, the use of the entire wind turbine surface is calculated to be required minimum power of the dynamo machine, which should be distributed to two juxtaposed, each other in case of need automatically complementary machines.

The performance of the wind turbine calculated in the following table is based solely on the full utilization of the wind attack surface, it is to be regarded as a minimum performance, which must be taken into account in the design of the dynamo. It is possible and quite probable that the factors of circulation in the air-thinned tree and the Hückstrahlantriebes at the most favorable lever arm with the calculation of utilization of the entire wind turbine surface alone have not been sufficiently considered · The practice of operation can result in a considerably higher performance ·
