Abstract

The windmill rotor wheel has a vertical rotary axis(5). It consists of three rectangular blades(3) fastened to the rotor hub(4). Each rectangular blade consists of several freely-pivoted air flaps (1), which have a horizontal or a vertical movement axis. The blades are automatically closed on the working side, forming a closed active surface. They are automatically opened on the non-working side to let the wind through. USE/ADVANTAGE - To generate electricity, with more favourable energy production than with ordinary windmills or wind-turbines.

Description

Probleme zur Ausnutzung von Windrädern und Windtürmen bestehen im schlechten Wirkungsgrad der Energienutzung. Die eigenen hohen Widerstandswerte und der bautechnische Aufwand führte zwangsläufig zur Entwicklung von Windmühlen und zu Windturbinen. Diese haben den Nachteil, daß bei größer werdenden Objekten die Arbeitsfläche (Drehfläche der Windflügel, die frontal der Windrichtung entgegensteht) zur Kraftfläche (Oberfläche der Windflügel, an der die Windkraft wirkt) ein ungünstiges Verhältnis zur Energieausnutzung darstellen.Problems with the utilization of wind turbines and wind towers consist in the poor efficiency of energy use. The own high resistance values and the constructional The effort inevitably led to the development of windmills and to wind turbines. These have the disadvantage that at larger objects the work surface (rotating surface the wind wing, which is opposite to the wind direction) to the force surface (surface of the wind wings on which the Wind power) has an unfavorable relationship to energy use represent.

Bei den entwickelten Windkrafträder mit selbstöffnenden vertikalen Windflügel besteht das Verhältnis Arbeitsfläche zur Kraftfläche immer 2 : 1. Damit entwickelt sich bei größeren Objekten ein günstigeres Energieausnutzungsverhältnis gegenüber Windmühlen oder Windturbinen.In the developed wind turbines with self-opening vertical wind blades there is the ratio of working area to the force area always 2: 1 larger objects a more favorable energy utilization ratio compared to windmills or wind turbines.

Durch die Entwicklung dieser Windräder bildet der Arbeitsflügel am Schließungspunkt der Anlage durch bewegliche Luftklappen eine geschlossene Fläche und die Windkraft trifft frontal auf diese.Through the development of these wind turbines, the working wing forms at the closing point of the system by means of movable air flaps a closed area and the wind power hits head-on to this.

Der Windflügel auf der Nichtarbeitsseite bewirkt eine Gegenkraft.The wind wing on the non-working side causes one Drag.

Durch die selbsttätige Öffnung der Luftklappen der Windflügel am Öffnungspunkt der Anlage auf der Nichtarbeitsseite, wird diese Kraft auf eine Minimalkraft beschränkt.Through the automatic opening of the air flaps of the wind wings at the opening point of the facility on the non-work side this force is limited to a minimum force.

Frei bewegliche Luftklappen, die als Prinzip für die Energieausnutzung bei Windräder dienen und nur durch die Windkraft geregelt werden, sind schon im Patent der Offenlegungsschrift DE 37 00 050 A1 Aktenzeichen P 3 70 00 500, Anmelder Johannes Hartmann, angewendet worden. Freely moving air flaps as a principle for the Use energy in wind turbines and only through that Wind power are already regulated in the patent Publication DE 37 00 050 A1 file number P 3 70 00 500, Applicant Johannes Hartmann has been applied.

Das Neue an den entwickelten Windrädern besteht darin, daß drei Windflügel aus frei schwenkbaren Luftklappen bestehen und beide Bestandteile, Windflügel und Luftklappen als gleichwertige und gleichwichtige Bedingungen eine Einheit bilden und für eine hohe Energienutzung der Windkraft notwendig sind. Diese Windflügel haben durch die Windkraft auf der Arbeitsseite eine geschlossene Flügelfläche und auf der Nichtarbeitsseite eine geöffnete Flügelfläche.The new thing about the developed wind turbines is that three wind wings consist of freely pivoting air flaps and both components, wind blades and air flaps as equivalent and equal conditions form a unit and are necessary for high energy use by wind power. These wind blades have on the working side due to the wind power a closed wing area and on the non-working side an open wing area.

Wind turbines with self-opening blades

1. The wind turbines consist of three 120 ° offset wind blades ( 3 ) which rotate about a vertical axis. These wind wings consist of rectangular wind flaps ( 1 ), which are attached to one side of the wind wing and have a freely pivotable vertical or horizontal axis on the wind wing.
2. The wind flaps are freely pivotable and the swivel range is limited by the support rods ( 2 ) against which the wind flaps can rest.
3. The wind flaps are opened and closed automatically by the wind power at the opening point (II) and at the closing point (I).
The opening point and the closing point always form an imaginary parallel line to the wind direction.
4. To the right of the closing point, the wind wings have closed wind flaps. The wind flaps are pressed against the support rods by the wind pressure. This is possible because the wind flaps can be pivoted in their suspension.
The wind power generates a high torque.
5. At the opening point, the Wind flaps by wind power. The wind pushes on the other side on the wind wing against the wind flaps. The wind flaps are pressed against the support rods and a wind wing with open wind flaps is created. The wind is almost ineffective and only creates one small torque.
6. An automatic closure takes place at the closing point the wind flaps. The wind presses the wind flaps on the other side against the support rods of the wind wing. The Wind wings have closed wind flaps.
7. Since the three wind vanes can be moved via the bearing ( 4 ) on the axis of rotation ( 5 ) of the wind turbine, there is a rotary movement which can drive a generator.

Claims

Right to wind turbines with a vertical axis of rotation, which consist of three rectangular wind blades offset by 120 degrees, which are mounted along the axis of rotation. These wind blades are characterized in that they consist of freely pivoting air flaps, the axis of movement of which is arranged either vertically or horizontally.
These wheels are used to generate energy.
According to the above-mentioned features, there is a claim to wind turbines whose wind wings are automatically closed on the working side by the air flaps and by the wind power (a closed wing surface is created) and are opened automatically by the wind power on the non-working side (a wing surface is opened to the wind) ).
Furthermore, the use of wind energy can be increased by installing air flaps on the wind wing several times. Clockwise or counterclockwise rotation of the wind turbines is possible by installing the wind flaps on the right or left side of the wind wing.
