• the invention relates to a device for using wind power with at least one rotor, wherein the rotor has a rotor shaft with vertically arranged axis of rotation, on the rotor shaft at least three support frame, each with at least one rotor blade are arranged and the rotor blades in the direction of rotation of the rotor in each case by the same angle offset from one another.
• the low efficiency is often due to the fact that the impinging on the rotor blades wind in addition to the leading surfaces of the rotor blades also always presses against the wind against the rotating backs of the rotor blades and flows only insufficiently at this. Attempts are therefore being made, inter alia, to appropriately redirect or divert the air flow with housings arranged in part around the rotors, but there is the disadvantage that the wind can only be caught from one direction.
• the object of the invention is to provide a device for using wind power with a vertical axis of rotation, in which the mentioned disadvantages are avoided and which has a higher efficiency compared to previous resistance rotors with a vertical axis of rotation.
• a device for using wind power with at least one rotor wherein the rotor has a rotor shaft with vertically arranged axis of rotation, on the rotor shaft at least three support frame, each with at least one rotor blade are arranged and the rotor blades in the direction of rotation of the rotor offset by the same angle to each other are arranged, is provided according to the invention that the rotor blades are arranged radially spaced from the rotor shaft, wherein between the rotor shaft and the rotor blades in each case at least one wind passage is trained.

The space available around the circumference of the rotor shaft is thus optimally utilized. Ideally, at least three rotor blades are thus arranged in one plane. The distance respectively
• the angle between the rotor blades should be as equal as possible and is preferably 120 ° for each of three rotor blades.
• a minimum distance of the rotor blades from each other is possibly to be determined as a function of occurring turbulence of the wind.
• the stability of the support frame of a rotor blade or individual support arms can be increased, that all in a plane perpendicular to the axis of rotation of the rotor arranged support arms or support frame are formed as a one-piece component.
• a strongly direction-dependent, changing load on the rotor or individual support arms or support frame can be effectively counteracted because distribute the forces generated by the wind and acting on the device to the entire component.
• the rotor blades and / or support frame can also be made heatable.
• the rotor blades are designed as horizontal cups, each having at least one of the rotational direction of the rotational axis of the rotor opposite cup opening.
• the air flowing into the cups is trapped and builds up pressure in the cup or cups, which is translated into a rotational movement of the rotor. It exceeds the Pressure in the respective cups the acting on the outer surfaces of the cup back pressure.
• Base of the pyramids is designed as a cup opening. This shape comes very close to the advantageous flow behavior on a sphere, so that the wind impinging on the convexly curved outer surface areas can optimally flow away from them. At the same time, with the i o base area of the pyramid, there is a large inflow area with which as much as possible

• the rectangular shape has over a square or circular base, for example, the largest possible inflow at the same height.
• the torque that can be generated by the device can be increased by an optimized wind load distribution on the rotor blades.
• the rotor blades arranged an asymmetrical curvature with an offset from its center to the outside
• the wind load center of gravity is dependent on the shape of the rotor blades and, in the case of a formed cup or pyramid, usually the deepest region of the cup or pyramid. Since the torque increases with the distance to the rotor shaft, the lowest point of the rotor blades is the cup as far as possible from the rotor shaft
• the rotor has support frames with rotor blades in at least two planes formed perpendicular to its axis of rotation, so that a plurality of rotor blades are arranged one above the other on the rotor shaft, which are each set at a different angle to the axis of rotation. This can do more overall
• Rotor blades are arranged as in only one plane without the rotor blades are adversely affected by possible turbulence of the wind.
• the torque which can be transmitted to a generator coupled to the rotor shaft is increased by a larger number of rotor blades.
• the amount of current or power of the rotor that can be generated by the device can thus be increased depending on the number of rotor blades.
• the rotor shaft of the rotor is arranged in a support mast.
• the device can for example be arranged at a higher altitude to use stronger winds.
• the support mast can fulfill other functions and serve as a mast, among other things. In a support pole, more rotors can continue to be arranged for the use of wind power.

• rotor blades 3 are arranged in three planes perpendicular to the support mast.
• Each of the three levels are associated with three rotor blades 3, so that a total of nine rotor blades 3 are arranged on the support mast 1.
• These rotor blades 3 are each held in a support frame 4, wherein each support frame 4 is composed of a first upper support arm 5 and a second lower support arm 6.
• the support arms 5 and 6 in a respective plane perpendicular to the support mast 1 are made of a one-piece component.
