Abstract

A multi-rotors shaft is disclosed having rotors are placed on a long shaft and upright to its axis 4, so that the shaft can transmit the torque of each rotor. The multi-rotors shaft may be used as a wind turbine or a river or sea turbine. The multi-rotors shaft may be placed vertically and when in use may be able to deflect and work in a position suiting the speed of the wind. The multi-rotors shaft may be used as a river or sea turbine, in which case the shaft may be placed in water at an angle to the line of the water flow or parallel to that line. The quantity, size and shape of the rotors, the distance between the rotors as well as the number of blades of each rotor depend on the parameters optimal for the specific working environment of the turbine and the durability of the materials of which the turbine is made.

Description

Multi-rotors shaft as a wind turbine or a river or sea turbine.
Technical Field
This invention relates to wind and water turbines.
The multi-rotors shaft as a wind turbine enables the construction of small and big industrial wind turbines at a much faster return pace of capital expenditures.
The multi-rotors shaft as a river or sea turbine enables the use of rivers as a renewable energy source without the necessity of building dams, and ocean and sea currents as a potential renewable energy source on a wide scale.
Background Art
The vertical axis wind turbine with blades for redirecting airflow, known from the invention description International Application No.: PCT/US2008/013606. Vertical axis wind turbines and Savonius blades incorporating an internal conduit for diverting a portion of an airflow incident on the blades are disclosed.
The submerged run of river turbine, known from the invention description International Application No.: PCT/EP2003/012731. The invention relates to a hydraulic power plant transforming hydraulic energy of a water flow by means of a hydraulic turbine. The inventive hydraulic turbine comprises a rotor, a generator and a float and is anchored in such a way that the rotor thereof is oriented in a direction of flow. In addition, said hydraulic turbine is floating under water surface and the float thereof is impinged upon by a gaseous medium or can be submerged.
Disclosure
According to the invention, the multi-rotors shaft as a wind turbine or a river or sea turbine is constructed as follows: rotors are placed on a long shaft and upright to its axis, so that the shaft can transmit the torque of each rotor. The quantity, size and shape of the rotors, the distance between the rotors as well as the number of blades of each rotor depend on the parameters optimal for the specific working environment of the turbine and the durability of the materials of which the turbine is made.
The multi-rotors shaft as a wind turbine is constructed in such a way that while not working the shaft will be placed vertically. While working the shaft is able to deflect and work in a position suiting the speed of the wind. The shape and positioning of the rotor blades enable the shaft to start rotating while in vertical position or slightly deflected. During the work in the deflection, the shape and positioning of the rotor blades enables the blade in the rotation phase rotating towards the wind direction to be a much greater resistance to air than in the rotation phase rotating opposite that direction.
The multi-rotors shaft as a river or sea turbine is constructed in such a way that the shaft is placed in water at an angle to the line of the water flow or parallel to that line. The shape and positioning of the rotor blades minimalizes the possibility of the rotors interaction to decrease the use of the water flow energy.
Description of Drawings
The subject of the invention in example is shown on the illustration in which fig. 1 presents on a diagram the multi-rotors shaft as a wind turbine not working, in vertical position 1 and fig. 2 while working, in deflected position 2 towards the wind direction 3, where 4 is the shaft's rotation axis and 5 is the rotor's rotation plane. The blade in the rotation phase, rotating towards the wind direction 6 is a much greater resistance to air than while rotating opposite that direction 2.
The subject of the invention is shown on the illustration in which fig. 3 presents on a diagram the multi-rotors shaft as a river or sea turbine while working, where 8 is the water flow direction, 4 is the shaft's rotation axis and 5 is the rotor's rotation plane.
Industrial Applicability
The subject of the invention can find its use as small and big industrial wind turbines, as river turbines enabling the use of rivers as a renewable energy source on an industrial scale without the necessity of building dams, and also as turbines which use sea and oceanic currents.
