The invention relates to renewable energy and can be used in the development of new types of wind turbines of various capacities operating in free air flow.

Known closest analogue (prototype) is a wind - and water systems with oscillating vertical blades (1), however she is able to balance the tilting forces only in water flows due to the large lifting force, a sealed hollow blades, while in the terrestrial version is not provided her emergency stop with simultaneous reversal of the blades by the air flow.

An object of the invention is to provide a compact, balanced on the tipping efforts, quiet, and safe wind turbines with advanced features allowing to optionally install them on the roofs of buildings, and in ship - decks non-self-propelled vessels.

This object is achieved in that provided in the wind turbine mount console with blades and coaxial with multi-pole generator with multiplier offset additional stationary bearing housing in the direction of the incoming airflow and positioned through the intermediate bracket on the upper area of the inclined rotary frame, rigidly connected in any�parts mounted on bearings in the bearing housing of the Central vertical shaft, which inhibited worm gear, connected through a pair of bevel gears with the shaft of a reversible DC motor electrically connected to a feathered node self-aligning blades on the wind, is placed on top of the Central shaft.

In the casing rotatable arm near the axis of the main blade is additionally secured with a locking plug and solenoid electrically connected to the emergency lever looper its power supply circuit, placed on the upper end of the rotary axis of the fixing console. Emergency stop console with blades in any range of wind speeds is performed using the external remote contactor power supply circuit of the solenoid.

In the absence of the supply voltage stop console with blades is performed manually using a connected with a locking fork long thin rope connected at the bottom of an inclined frame with tensioning the pivoting arm.

For uninterrupted consumption of electricity generated by the unit is equipped with technical means (electrochemical and oxygen-hydrogen) conversion and accumulation of its redundant parts at night and during periods of strong winds, and shipboard design - also when at anchor, and use it as a mobile Autonomous floating elektrostanciya electricity onshore non-electrified settlements and other remote energy facilities. Placement on the deck propelled boats (preferably the most stable catamaran with two units), gives him the ability to swim for an unlimited time without consumption of hydrocarbon fuel and without sailing equipment.

Fig.3 is a side view of the key power-generation facilities within the stationary bearing housing.

Fig.4 is a side view of a placement within the housing rotatable arm locking plug, solenoid and bracket with cable (a) and top view of the locking fork ().

Fig.5 is an electric circuit installation (P. U. - moving parts enclosed by a dotted line).

The installation includes a swivel arm 1 is placed on the casing 2 of the main 3 and auxiliary 4 blades mounted by node 1/on the vertical axis 5 and held in a horizontal position�AI rope stretching 6 with stretch lanyard 7, and the axis 5 is connected through the multiplier 8 with multi-pole generator 9 that the proposed structural solution is shifted in the direction of the incoming airflow.

Installation is further provided with placed on the axis 5 of the bearing bushing 10 is fixed thereto intermediate the bracket 11, the base of which is connected by bolts 12 with the upper horizontal area of the inclined supporting frame 13 mounted thereon with the two cheeks 14 having horizontal slots for attachment thereto of a multipolar generator 9 with a multiplier of 8. Frame 13 in the lower part is rigidly connected with a hollow Central vertical shaft 15, the upper end of the vane 16 with the contact group of the switches 17 and the internal wiring 17/and the lower part of the shaft 15 is placed on the thrust bearings 18 and 19 in a stationary bearing housing 20 held by the support brackets 21. Inside the housing 20 on the shaft 15 planted its inhibitory worm wheel 22, articulated through a horizontal worm shaft 23 and a pair of bevel gears 24 with the shaft of a reversible DC motor 25 is electrically connected with a feathered switches 17.

Inside the housing 20 is also placed three phase power rectifier 26, a voltage regulator 27 for internal charging buffer battery 28, a power collector tacos�the receiver 29 and distribution low-voltage collector current collector 30. On the upper end of the shaft 5 is placed (excessive tilting airflow) emergency box 36 with push-button contactor 37 of the supply circuit of the solenoid 38, the spindle through which a spring plate 39 is connected to the lock plug 40 is held by the bracket 41 and is connected by means of the return spring 42 with the bracket 43. At the end of the rod of the solenoid 38 fixed, movable bracket 44 connected via a guide Bush 45 with long thin rope 46 is outputted outside from the shell 1 and connected to the rotary tensioning lever 47, mounted in the lower part of the supporting frame 13.

The installation operates as follows.

Assembled on site installation is placed on level ground (mast, elevated position, the roof deck non-self-propelled vessel, etc.). Dual sections of the blades 3 and 4 are easily removable, so they can be fixed to the stationary casing 2 of the console 1. When fixing the intermediate arm 11 by the bolts 12 on the upper horizontal surface of the inclined support frame 13 is preferable its displacement in the direction of the incoming wind flow for more dynamic compensation of the tilting influence generated mainly operating blades.

Feathered the system performs self-blades on the wind itslegal change its direction within 360° as follows.

When the direction of incident flow angle ±αpexceeding the angle of free lutcavage of rotation α0weathervanes 16, closes the left or right of the contact group, tandem switches 17 (for example, type P2T-5), and on their reverse the motor 25 through a pair of bevel gears 24 and a pair of worm 23,22 will turn in the same direction and at the same angle to the Central shaft 15, with the plane of the vane 16 will again be focused on to the air flow, and Rusakovskaya switches 17 will spontaneously return to a neutral intermediate position (Fig.5) and disable the reversible motor 25.

High wind speeds, for example - more than 30 m/s, pre-calibrated emergency box 36 leans down and closes the contacts 37, lured into the coil of the solenoid 38 of the stem (Fig.4a) via a spring plate 39 pushes the plug 40 at the same time the two levers 48 and 48/transverse rocker, planted in the centre of the axis of the main dual blades 3, and if it finds it in the far right II or III in the left positions (Fig.2), i.e. in the process of reverse air flow to start the reciprocating motion in the opposite direction, at the time of coincidence of the plane with the axis of the console 1, the grooves 49 of the plug 40 will be locked with the levers 48 and 48/and will hit a jam on the axis lipasti, and associated auxiliary axis of the blade 4. Both blades are in the feathered mode, rotates in the wind to position I and during the storm (or storm) will be deployed to keep on to the air flow, including when you change its direction. After the weakening of the wind to the operating values, for example below 30 m/s, the box 36 is lifted up, weakened the stock solenoid with a spring plate 39 and the return spring 42 returns to its original position, the plug 40 is open at the top (Fig.4a), and the blades in a production (Fig.2). Finding console with blades in extreme positions has no significant effect on the overall balancing of the installation.

Before performing planned maintenance or repair work with disabled supply voltage is performed manually, the locking plug 40 to the axis of the main blade 3 with further planted on the stem end of the bracket 44 and associated with a thin long rope 46 pivoting the tensioning lever 47 by turning it down. After completion of the work the lever 47 necessarily translates in an upper position, wherein the plug 40 is opened with the levers 48 and 48/and the blades spontaneously return to operating position.

In ship design, especially when using a whisker�of anouki as a stand-alone power plant it is additionally provided with technical means of electrochemical, oxygen-hydrogen, or other accumulation of excess electricity produced for an uninterrupted supply of her internal and external customers.
