Abstract

The wind multiturbine for the use of wind energy in a multi-rotor manner comprises a rotor shaft (1), which is mounted in a holder (13) in a pivotal and rotatable manner. The blades (4) are attached to a bearing (8) and arranged in at least two rotors one above the other, reinforced by the lower profiles (5) and suspended on profiles (3). Mountains, gutters, saddle and flat roofs, sides of vehicles and ships can serve as a transverse surface (12) for lifting the air flow. The multiturbine, when properly arranged, almost removes the load on the foundations, which is especially welcome in the mountains and at sea level.

Description

Technical field

The technical solution relates to wind multiturbines for the use of wind energy, where one unit contains a plurality of rotors with the intention of increasing the unit power without extreme rotor diameters.

Prior art

Previously known multi-rotor systems from model tests use branched columns to arrange several rotors next to each other. It is also known to suspend a plurality of rotors on a longitudinal horizontal axis or rope.

The twin-rotor system with opposite Mouths allows wind direction and more efficient transmission. All of these systems remain at relatively high cost for columns, foundations or anchorages.

The essence of the technical solution

The essence of the technical solution is the axis of the multiturbine rotors, whose attachment in the lower part in the holder allows rotation around the vertical pin eccentric and tilt and tilt of the multiturbine axis on the transverse axis, which allows rotation according to wind ascent and axis tilt allows protection against excessive wind they are arranged along the axis in several rotors on a rotary bearing, thus achieving a more efficient upward flow and a sufficient transverse catch surface.

The leaves are suspended on pairs of profiles by partitions in front of and behind the leaf profile without interference resistance and the weight of the leaves absorbs the buoyancy force together with the lower profiles. The generator can be driven in the lower part of the bearing via a gear drive or it can be mounted in a micro-chute on the arm between the rotors and driven directly by the microturbine. The transverse surface across the wind direction and the rudder is suspended below the axis of the column and causes the input flow as well as the force effect on the stability of the column.

As a transverse surface, a dispositional terrain, a building, a flat or saddle roof can be used, at very high performances also slopes of mountains, ridges or gutters supplemented by directional surfaces spaced and concentrating slope or thermal flow. The side of a mobile device or vessel, e.g. caravan.

Overview of figures in the drawings

The picture shows a side view of a wind multiturbine, which is located on a flat roof and at the top of a hill.

Examples of embodiments

A micro-wind turbine on the saddle roof of a family house designed to drive a heat pump with an output of 1.5 kW. The shaft 1 is set to an inclination of 15 ° by the stop of the holder 13. The blades 4 are arranged in pairs into three rotors for bearing 8. The direction of the buoyancy forces from the rotors is to the root of the column 11, from which the roof-sloping beams emerge are loaded by tubes at their ends. The load is sufficient to absorb forces at rated wind. Excessive wind will clamp the V-shaped rudder 2 and the increased buoyancy of the blades 4 will forward the axis 1 with the rotors to a reduced angle of attack and low load. Attached to the housing 8 is an arm with a micro-trough which rotates at a peripheral speed of up to 20 m / s. The high speed of the turbine in the micro-trough rotates the DC generator directly and the current is collected by a collecting ring in the lower part of the shaft LV in case of snowfall (dashed in the picture) turbine generated in generator 7 supplies a heat pump of 5 kW. The blades 4 are reinforced with profiles 3 and lower profiles 5 in the brackets on the partitions 6. The change of wind direction rotates the rotor 2 on the vertical axis 9 by the direction 2, the inclination is adjusted on the horizontal axis 10.

Another embodiment is a mountain wind power plant of the order of 50 MW. Blocks directing the wind to a multiturbine with a diameter of 150 m will be built in cross lines on a suitable mountain ridge. An ascending and concentrated air stream with a speed of 25 m / s and a higher conversion efficiency thanks to three rotor stages produces power that is the result of mountain potential and allows wind capacities to be directed to the mountains for economic advantage and low demand for wind multiturbines.

Another embodiment is powering the ship's electric drive. The side of the ship, including the height of the superstructure on board or the cargo, serves as a transverse surface 12. The buoyancy of the sheets 4 creates only a minimum load moment on the ship.

Sailing is possible obliquely against the wind and perpendicular to the wind, while the boat is powered by an electric motor. Wind navigation is optimal for multi-turbine propulsion, with a significant reduction in battery power consumption. The batteries are recharged by canceling the drive and pushing the wind multiturbine at a lower speed.
