The invention relates to wind and can be used to develop mechanical drives reciprocating reciprocating and centrifugal pumps and other consumers of mechanical energy.

A known design of wind turbines with a vertical axis of rotation is nematicheskii associated with the hydraulic pump (ed.St. USSR N 1560782, CL F 03 D 5/00, 29.04.88).

Closest to the present invention is a device microbrewed with tower and turret with rocker, kinematically connected to the hydraulic pump, and means pivoting the bearing plane that is installed on the rocker (U.S. patent N 4525122, CL F 03 D 5/06, 25.06.85).

This device is complex, unreliable and short-lived system reversing carrier plane at the end of the stroke of the rocker arm.

The aim of the invention is to simplify the construction and increase the efficiency of microbrewed.

For this vetropriemnoe work the body in the form of at least one horizontal aerodynamic bearing surface symmetrical profile with flat end plates, hinged to the rear part of the rocker arm, which is pivotally mounted rotary sectors and the rotary lever connected with a hard thrust with hinges in the middle and at the ends and the pivot point for the rear swivel sector that is installed on the lever bearing surface, the swivel lever and front swivel sector, and provided with a bracket located on the swivel head with the pivot for the rocker arm, stops for turning sectoe the other hinged to the rocker, flat washers placed on both ends of the bearing surface symmetrical profile, and a counterweight on the arm.

In Fig. 1 shows the construction of microbrewed during rotation of the rocker arm counterclockwise, Fig. 2 the same, rotating the rocker arm in a clockwise direction, Fig. 3 petroprod.

Vetropriemnoe work the body in the form of at least one horizontal aerodynamic blades symmetrical profile rectangular, trapezoidal or arrow-shaped form in plan with lengthening 5-10 and angle of sweep 30about. The blade 1 with the flat end washers 2 triangular hinged to the rocker arm 3, is installed on the hinge lugs 4 and 5, a rigid rod 6, which lever 7 of the blade 1 and the pivoting arm 8 forms a parallelogram mechanism, and the rotation axis of the blade 1 relative to the rocker arm 3 is located behind the center of pressure surface of the blade.

Arm 3 pivotally mounted on the bracket 9 having lugs 10 and 11 to the hinge lugs 4 and 5, and also dip the groove 12 with supports for the pivot arm 8. The bracket 9 mounted on the rotary head 13 rotary hinge at the top of the tower 14. In front of measures by the piston rod of the hydraulic pump 16.

The blade 1 has a cutout in the middle part of providing its rotation relative to the rocker arm 3 and the positive angle of attack when lifting the rear part of the rocker up. Possible microbrewed with the bearing surface without cut while ensuring a sufficient length of the lever.

To simplify the design and increase the efficiency of the proposed petroprod is achieved by the fact that the working stroke of the consumer of mechanical energy, such as a hydraulic pump, is provided by the tangential component of the total aerodynamic force bearing surface. Power elements of microbrewed perceive minimum load representing the radial component of the resultant aerodynamic forces adobeimage body with integral washers, which allows taking into account the necessary margin of safety to implement a smaller weight in comparison with the prototype design petroprod, reduce consumption, cost, improve reliability, durability and competitiveness. Improving the efficiency of the proposed petroprod is also provided so that reverse rotation of the bearing surface is at the very end of the stroke and the maximum lifting force of the wind longer affects abeen a more efficient system orientation to the wind. The absence of high-frequency oscillations of the air flow makes the proposed drive compared to rotary environmentally safe.

Petroprod works as follows.

Incoming flow (wind) acting on the blade 1, creates a complete aerodynamic force, the resultant of which is attached in the center of the pressure surface of the blade. The optimum angle of attack of the bearing surface of the blade 1 with respect to the incident wind flow is provided by the constant in the process of turning the rocker arm 3 (stroke) due to the clamping of the moment due to the substantially front location of the center of pressure of the bearing surface of the blade 1 with respect to the axis of the swivel bearing surface and the rocker arm, and adjustable end stops end positions of the rotary lever 8 dip in the groove 12 of the bracket 9.

The tangential component of the resultant aerodynamic force bearing surface 1 generates a torque, which is the position of the beam 3 with respect to the bracket 9 around the horizontal axis of the swivel. In the process of turning the rocker arm 3, for example, counterclockwise (Fig. 1) the supporting surface 1 is rotated relative to the surface tends to rotate it clockwise, but rigidly connected with the lever 7 of the bearing surface of the blade working on a bend, stretches your hard rod 6, the ledge which rests against the adjustable back rest-position of the groove 12 of the bracket 9 and prevents rotation of the bearing surface 1, while the lever 7 of the bearing surface, hard thrust 6 (rear) and the rotary lever 8, pivoted on the yoke 3, form a parallelogram mechanism. The axis of rotation of the rotary lever 8 coincides with the axis of rotation of the rocker arm 3.

Hinged to the rocker 3 rod 15 through a spherical joint 17 transmits reciprocating motion to the consumer of mechanical energy, for example porshneva the hydraulic pump 16 bilateral actions.

When the piston rod of the hydraulic pump 16 to the position close to the extreme bottom, front hinge emphasis 4, hinged to the rocker arm 3 and the front part of the hard thrust 6, comes into contact with the front stop 10 of the bracket 9. Upon further movement of the rod down to the extreme lower position under the influence of the lifting force of the blade 1, the upward, the front part of the rocker arm 3 continues to descend, and the front swivel stop 4, resting his flat lower part of the roller is remedy rod 6 forward until it contacts the upper part of the rotary lever 8 with front adjustable dip groove 12. In the process of moving 6 forward thrust bearing surface of the blade 1 by means of its lever 7 is rotated counterclockwise by an angle equal to two optimal angles of attack for a given configuration and the estimated wind speed. Incoming flow of wind creates a hinge point, which, through the lever 7, the rear part of the hard thrust 6 and the rotary lever 8 presses the upper part of the front adjustable focus off of the groove 12, the locking is negative with respect to the direction of the wind attack angle of the bearing surface of the blade 1. The rear part of the thrust 6 operates in compression. Under the action of the tangential component of the total aerodynamic force bearing surface of the blade 1 along with the rocker begins to move down, turning it clockwise (Fig. 2), which provides a new working stroke up the shaft of the hydraulic pump 16. Dynamics of change of the angle of attack of the blade 1 on the opposite signs is taken into account by adjustment of the stop of the dip of the groove 12 and the length of the rod of the hydraulic pump 16.

In the process of turning the rocker arm 3 in a clockwise direction (Fig. 2) the bearing surface of the blade 1 is rotated relative to the rocker arm 3, while maintaining an optimal and constant angle of attack, providing the Maxim of the arrows, but this was prevented by the contact of the upper part of the rotary lever 8, pivotally connected to the rear part of the hard thrust 6, through which the lever 7 transmits the compressive force from the hinge point of the bearing surface of the blade 1, with front adjustable dip groove 12 of the bracket 9.

When the piston rod of the hydraulic pump 16 to the position close to the upper, rear hinge stop 5, fixed to the arm 3 and is constantly resting his flat upper part of the roller lug rear hard thrust 6, is in contact with the rear stop 11 of the bracket 9 (Fig. 1). Upon further movement of the rod and rod 15 upward to the upper position under the influence of the tangential component of the total aerodynamic forces bearing plane of the blade 1, the downward, the rear part of the rocker arm 3 continues to descend, and the rear pivot stop 5, adjoining its bottom flat part with the roller prop 11 begins to rotate clockwise about the axis of its hinged attachment to the rocker 3, shift rod 6 back up until the rotary lever 8, pivotally connected with a hard thrust 6, no abuts the rear of the adjustable dip groove 12. When this hard what about the rocker arm 3 from the toe down to position the toe up. Emerging lifting force of the supporting plane, pointing up, starts to raise the rear part of the rocker arm 3. This point is shown in Fig. 1. Started a new working stroke of the hydraulic pump 16 double-acting or any other consumer of mechanical energy.

Petroprod provides a constant force on the deadlift 15 to the consumer in the greater part of the stroke when the reciprocating swinging movement of the supporting plane of the blade 1 through a constant angle of attack.

Setting the angle of attack of the bearing plane of the blade 1 is carried out by means of adjustable stops end positions of the rotary lever 8 dip in the groove 12, the adjustable stops 10 and 11 of the end position of the rocker arm 3 with respect to the bracket 9 and the variable length of the rod 6 with the relative speed of movement of the carrier plane.

Install the bearing plane of the blade 1 to the wind and reduce induced drag are provided with integral washers 2, rotation of the bracket 9 mounted on the rotary head 13 rotary hinge at the top of the tower 14, around a vertical axis and a shoulder between the vertical axis and the center of pressure end plate 2. When the wind direction changes bokovo wind. Spherical hinge 17 is designed as a rotating thrust 15 together with the upper part of microbrewed relative to the vertical axis of the tower 14 in the orientation of microbrewed in the wind, and the oscillatory motion of the thrust 15 in a vertical plane in the process of microbrewed.

In the case of sufficiently high tower 14 is used sectional hard thrust, the deflection of which is limited to roller bearings.
