(57) Abstract:Usage: in the wind industry. The essence of the invention: method of conversion of kinetic energy to the speed of the wind acting on the tethered flying machine, which performs reciprocating motion in a vertical plane on seerah bridle attached to the connecting rod ring crank. The wind turbine includes a tethered flying machine, Reitern support 9, the worm shaft 10, Reitern lever 20, the crank 3. 2 C.p. f-crystals, 4 Il. The invention is used to convert the kinetic energy of the velocity of the wind acting on the tethered flying machine (PLA), mechanical work, with the downlink transmission of mechanical power to exclude capital expenditure on the construction resistant to wind loads of a high tower, Foundation, improve ROI installation.In the first half turn of the crank (arc c-d-a, Fig. 4) around its axis, due to inertia forces, when shortened size bridle PLA lUSD1(Fig. 4), with a smaller angle of attack (Fig. 4) the crowding of the wind flow on the PLA, which corresponds to the mode of preparation (steaming), force the windshield soprotivlenie finger crank (point "P", Fig. 4). The result is committed rotational motion of the crank 3 (Fig. 2 and 4) PLA moves learni towards wind flow W (Fig. 4) to complete this half rotation of the turnover of the crank, while the Cam mechanism, organized by the Cam pair 4 and 5 (Fig. 2 and 3) (shaped Cam which is mounted on the shaft of the crank), at the end of this half turn (arc c-d-a, Fig. 4) acts through the clutch Cam 5 (Fig. 2) on the lower shoulder Reitern lever 20 (Fig. 2 and 3), which leads through the cable 16 (Fig. 2) the angular displacement of the pumping unit 15 (Fig. 2) installed on it by the roller 8 (Fig. 2) managing size bridle PLA, resulting PLA mode with a longer bridle lUSD2(Fig. 4), which corresponds to the mode of the stroke arc a-b-c (Fig. 4), and traction of lierow 1 and 2 (Fig. 1 and 2) attached to the connecting rod finger crank (point "P", Fig. 4), on the radius of the installation rod finger creates a torque on the crank shaft (axle shaft O-O Fig. 2 and 3) a larger value than in the first half of the turnover of the crank shaft. Upon further rotation of the shaft, at the end of the second half of the turnover of the crank Cam mechanism again in Reitern lever system moves the ice rink 8 (Fig. 2), operated the Fig. 1 and 4). The combination and sequence of activities used funds for one full turn of the crank creates a different amount of torque, the difference of which is useful work (power) on the crank shaft (axle shaft O-O Fig. 2 and 3).Device description wind turbines under item 1 to specify the length difference bridle PLA mode sweating and mode of the stroke to regulate power.Switching PLA from mode I to mode II (Fig. 1) is controlled by the position of the profiled Cam 4 (Fig. 2), the profile of which corresponds to these modes. Bearing slave Cam 5 (Fig. 2 and 3) made integral with the plunger pump 22 (Fig. 3) depending on the angle of rotation of the male performs a linear reciprocating motion along the axis of the plunger pump 22 (Fig. 3) and leads via a lever-cable system 16, 15, 2 (Fig. 2), 20 (Fig. 3) change the size of the bridle Uz 1 size Uz 2 (Fig. 1), which determines the acting force of the wind on the PLA due to the aerodynamic resistance of the PLAN and, therefore, the capacity of wind turbines. Linear position supports Reitern lever 9 (Fig. 2 and 3) along the length of the worm drive shaft 11 (Fig. 2; 3) specifies the ratio of the shoulders Reitern arm B1:B2 (Fig. 2) and sets the difference is CA of these points generates a current speed of the crank shaft power output of the wind turbine. The change in the ratio shoulders B1:B2 depending on the speed of the wind flow W (Fig. 1) leads to a change in output power installation.Device description wind turbines under item 1 to specify the external length of the Leer bridle to compensate for exhaust Leonov during operation of the wind turbine.Ropes (cables) 1 and 2 (Fig. 1 and 2) during operation, due to the different levels of tractive effort, pulled from the size of the initial lengths vary and, as a result, changing the difference of the lengths of the bridle Us - Us (Fig. 1) in the operating mode II and mode of soaring I.The device allows you to change the initial external length Leer bridle 2 (Fig. 1 and 2) from the rink 7 (Fig. 2) to the opposite node sealing Leer bridle on PLA by reducing (increasing) center-to-center distance between the roller 7 (Fig. 2) guy wire bridle and profile of the Cam 6. Bearing rink delays 7 pivotally connected to the end of the worm shaft 10 mechanism of delays, the rotations of the worm shaft 10 clockwise (or counterclockwise) change the center distance rollers 7 and 6, and this is achieved by changing the specified external length Leer bridle.Confirmation of the availability of the invention.In the present invention, prgnam object in the necessary volume for the object of the invention.In Fig. 1 shows a kinematic diagram of the PLA of Fig. 2 - the same, the ground portion of the installation of Fig. 3 is a General view of Fig. 4 - an explanation of the operating principle.The sources of information.1.

SUBSTANCE: invention relates to on-coming energy converters used in wind-power engineering, hydraulic power engineering and instruments. In proposed method two physical are used simultaneously, namely, self-excited oscillations and electromagnetic induction. Conversion of energy of on coming flow is provided due to electromagnetic induction appearing at self-excited oscillations in metal strings (flexible conductors) arranged in on-coming flow and placed in magnetic field. According to law of electromagnetic induction, metal string executing oscillatory movements in magnetic field becomes electric energy (current) generator.
EFFECT: increased power output of converter by increasing number of strings to required value.
