Description

The invention relates to wind energy and to transport powered by an electric traction system from its own energy sources.

Known wind power station (BC) (see the journal "Technique of Youth", No. 11, 1982, M .: Young Guard, p. 1, item 6), which contains a turntable on which a metal tower is mounted in the form of a trapezoid , on top of a cylindrical streamlined body of the engine room with a nasal wind turbine, which contains rotary rectangular blades, adjustable by angle of attack, in the engine room: gearbox, electric generator, standby heat engine and automatic control units.

On this BC, the density of the wind turbine blades in the circle they sweep is low, their high height and small width, which have a low coefficient of utilization of wind energy in the circle. The large installation height of the engine room has a high metal-intensive tower, as well as the rotation mechanisms of the platform on which it is installed. BC carries power losses in the power line to the consumer.

The problem solved by the invention is:

- increase the utilization of wind energy in the swept circle of the wind turbine;

- reduce the cost of turning the platform;

- install BC on land on a self-propelled running carriage, on the deck of the vessel instead of sailing weapons, i.e. thus expand the scope of use.

The essence of the invention is as follows: a self-propelled wind power station containing a rotary circular orientation platform, a vertical pylon, a wind turbine, an engine room with a gearbox, which houses a heat engine, an electric generator and automatic control devices, a wind turbine stator with a hollow shaft, in the tail of which is made in the form of a drum, rotary blades are installed, the wind turbine is installed by the center of its pressure on the pylon, in the nose of which, as opposed to placed Ashina compartment pylon mounted on a turntable placed on the undercarriage, provided with wheels with a ballast resistance, and the two diagonally located wheels are provided with motor-reducers, and a stator and a turbine rotation axis has a negative angle, providing yaw downwind tail of the wind turbine.

In addition, the rotary blades are made in the shape of a dovetail with a concave surface profile along a parabolic curve and are perforated by oblique slits of the suction of the boundary layer with a cross section in the shape of a crescent-crescent moon, swept downstream.

In addition, the output shafts of the wind turbine and heat engine in the gearbox are equipped with overrunning clutches.

In addition, in the cavity of the drum, articulated levers for turning the blades are mounted, mounted on the cross of the rod located in the hollow shaft, while it is pivotally connected to the servo slide on the stator in the bow of the shaft.

In addition, flashing beacon lights are installed on the blades with rays aimed at the unmasked surface of the distant visual detection and identification of the station.

In addition, the running wheeled trolley is made with a rectangular prefabricated frame, equipped with an upper deck in the center for the turntable and a pivot device, mounted on four wheels at the corners of the trolley.

In addition, trapezoidal elastic track shoes with cross sections in the shape of a trapezoid, equipped with a chain-link chain with increased wear resistance are installed on the rims of the twin wheels.

Self-propelled wind power station (SHS) contains a rotary platform 1 (Fig. 1), a pylon 2 is installed on it, which is streamlined by a free flow, a stator housing of a wind turbine 3 with a negative angle α to the plane of the rotary platform is installed on it, a hollow shaft of the wind turbine is mounted on bearings 4. A blade (dovetail) 5 (Fig. 1, Fig. 2) with oblique slots 6, stiffness shelves 7 is installed on the tail end of the shaft of the drum on a rotary axis with a negative angle β to the plane of rotation; Fig. 3 shows a trace in boundary layer, lamy outer sublayer 8. Lights of a flashing beacon are installed on the rotary blades 9. On the pylon 2 at the bottom in the bow there is an engine room with a reducer 10, in which an electric generator 11 and a heat engine 12 are located. A driven gear of the electric generator is installed in the gearbox 13 (Fig. 4) 14 with gearing with the driving gear of the wind turbine 15 and the thermal 16. In the hollow axis of the driving gears on the output shafts, the ball overrunning clutches of the wind motor 17, the heat engine 18 are mounted.

Work SHS.

By the force of the wind, the autodevice set the angle of attack of the incoming flow on the rotary blades, a torque was created on the axis of the wind turbine, which is transmitted through the shafts and gears to the shaft of the electric generator and holds the optimum torque on it under load. The yaw center of pressure of the wind turbine keeps the incoming flow on the rotary blades at the optimum angle of attack. Engine room - the counterweight smoothes lateral wind blows on the rotary blades.

The wind force is lower than optimal: a critical angle of attack on the rotary blades is set by the auto device, a heat engine is launched, which increases through the overrunning clutch, supplements the torque of the wind engine with obtaining the optimal generator on the shaft.

On the driving wheels of the running wheeled trolley of low speed connected el. current. Email the engines tell them to rotate, when turning in place - in different directions, when turning sideways along a curve - it is controlled by the speed of the right or left electric motor.
