The invention relates to the field of renewable energy sources, namely wind energy devices.

Known wind turbine with a vertical shaft and flat blades, the orientation of which varies with wind direction [EN 2046208 C1, F03B 17/06, 20.10.1995].

To change the orientation of the blades you use a disc with profile surface kinematically associated with the vane. The blades have a horizontal axis of rotation, the root part which has rollers that interact with the profile surface of the disk and change the orientation of the blades. Blades that create a positive torque on the vertical output shaft, oriented perpendicular to the wind. Other blades take a horizontal position and do not hinder the rotation of the propeller.

Known wind turbine has a complex structure and it is not provided for synchronizing the speed of rotation of the output shaft while changing a speed of the wind.

Also known wind turbine [EN 2151322 C1, F03D 3/00, 20.06.2000], which provides for the synchronization of the speed of rotation of the output shaft, which can be specified as a prototype of this technical solution.

In the prototype, the height profile of the disk varies depending on wind speed and adjusts the effective area of the blade. The more imminent is the efficiency of the wind, the smaller the effective area of the blades. The blades are set at an angle to the horizontal plane.

The disadvantage of the prototype design is the complexity of the wind turbine due to the complexity of the construction site of interaction between the vane profile disk and changes the effective area of the blades, as well as the low efficiency associated with sinusoidal change in the length of the lever.

Also known wind turbine Aliyev [EN 2224135 C1, F03D 5/00, 20.02.2004], which can be specified as a prototype of the fourth version of the energy Converter. The prototype has a flat blade that interacts with a conical vane mounted in the center of the wind turbine. Blades that create a positive torque on the output shaft, automatically oriented perpendicular to the wind direction and retain the same orientation throughout the active portion of the trajectory of rotation of the blades. On the passive trajectory of rotation of the blades are oriented along the direction of the wind.

However, the prototype has a complex structure and low efficiency associated with the fact that the active portion of the trajectory of rotation of the blade is 90-120.

The technical objective of the invention is to simplify the design of the inverter energy (wind turbine) and increase efficiency.

This technical problem, the solution is carried out by developing a radically new design coliblue wind turbine which includes a rack, a fixed platform and kinematically associated vertical shaft, the flat of the blade, the node changes the orientation and fixing the position of the blades, vane, and also interacting with each other the turntable, the second node changes orientation and fixing the position of the blades, the first, second and third rod with the stars, connected by a chain, site converting oscillatory motion into rotational and node synchronization speed and rotation. While the first and second nodes change the orientation and fixing the position of the blades interact with the first rod, and rod pivotally mounted in a vertical shaft on the same vertical line with the possibility of free rotation. In addition, at the ends of the rods still installed first and second flat blades are oriented in mutually perpendicular planes. When this rotary platform mounted on a fixed platform with the possibility of free oscillations in the range of 90.

Each of the nodes change the orientation and fixing the position of the blades mounted on the first rod, consists of interacting with each other plate, pawl, the locking ring with two rapovymi ledges, spring twist, overrunning clutch, to a holder which is still installed star interacting with the segment circuit is, fixed on the rotary platform. On a turning platform also installed the first and second stops interacting with the corresponding dogs, hinged on plane-parallel plates fixedly connected with a vertical shaft. In addition, the retainer ring still connected with the rod and through the spring spin interacts with the overrunning clutch hub freely rotatable on the rod.

Site converting oscillatory motion into rotational includes a housing, first, second and third bevel gears, the first and second overrunning clutches and shaft. On the output shaft still installed hub first and second overrunning clutches, the clips are secured in position corresponding to the driven bevel gear interacting with diametrically opposite sides with third leading bevel gear fixedly installed in the end portion of the vertical shaft. While the first and second overrunning clutches are installed so that fluctuations of the vertical shaft in the direction they were in the grip of the queue.

The principle coliblue wind turbine design is shown in figure 1 and figure 2, is as follows.

With the help of inclined racks 1 stationary platform 2 is raised to the required height, to ensure the safe operation of a wind turbine and where the wind speed is high enough. Over a fixed platform is mounted rotatable horizontal platform the PMA 3 with the possibility of free rotation in the range from 0 to 180. This platform is still connected with the conical vane and changes its position depending on the wind direction. A turntable pivotally connected with a vertical shaft 4. Vertical shaft through a radial-thrust bearings 22 is connected to the rotary platform 3 and node converting oscillatory motion into rotational 14. The vertical shaft has a possibility of oscillatory movement relative to the rotary platform 3 in the range of 90. Through the vertical shaft 4 passes through the lower rod 5 and the second 6 and third rod 7. The rod is made in the form of a pipe and is installed on the same vertical line with the possibility of free rotation around their own axes. At the ends of the rods fixedly mounted right 8 and left 9 flat of the blade. The plane left and right blades are perpendicular. When the right of the blade 8 is oriented vertically, the left blade 9 is oriented horizontally, and Vice versa (see figure 1). After a half-period of oscillation of the rod orientation of the blades is changed. The horizontal blades 9 are in the vertical position and the vertical blade 8 is in the horizontal position. Simultaneous change of orientation of the blades 8 and 9 is carried out using a third of the stars 10 and the chain 11, the relationships between them. Third star fixedly mounted on the rods 5, 6, 7. Changing the orientation of the lower blades etc which leads to a concurrent change of orientation of the upper blade, installed on the second 6 and third 7 bars. Changing the orientation of the blades mounted on the first rod 5, by using the first 12 and second 13 knots change the orientation and fixing the position of the blades (see figure 2 and figure 3).

The lower end of the vertical shaft 4 is pivotally connected and communicates with a node in the transformation of the oscillatory motion of the vertical shaft into rotational motion of the output shaft 20. Radial thrust bearing 22 mounted in the cover 23 of the node transformation movement 14, centers and holds the shaft in a vertical position. At the lower end of the vertical shaft still installed leading (third) of bevel gear 17.

Through the side faces of a rectangular body 21 of the motion Converter 14 horizontally passes the output shaft 20 of a wind turbine. On the output shaft still installed hub first 18 and second 19 overrunning. The clips of these couplings is secured in position corresponding to the driven bevel gears 15, 16. These gears are coupling with a driven bevel gear 17 with diametrically opposite sides. In addition, the first 18 and second 19 overrunning clutch mounted on the output shaft 20 so that they were in the grip of the queue when the oscillation of the shaft at the other side.

When the right blades 8 are in a vertical position, Vertica the capacity shaft is rotated 90 counterclockwise. The clutch includes a first overrunning clutch 18. The interaction leading bevel gear 17 with the first driven bevel gear causes the rotation of the output shaft clockwise. At this time, the yoke of the second overrunning clutch 19 and the associated second bevel gear 16 spinning idle clockwise.

After a half-period of the orientation flat of the blades 8 and 9 is changed to the opposite. This causes rotation of the vertical shaft clockwise by 90. The clutch includes a second overrunning clutch 19. The interaction leading bevel gear 17 with the second driven bevel gear causes rotation of the output shaft 20 in a clockwise direction. At this time, the first overrunning clutch 18 is outside of the clutch and the first bevel gear rotates idle counterclockwise. Thus, the oscillatory motion of the vertical shaft is converted into rotational motion of the output shaft clockwise.

Figure 2 presents a view of the figure 1 design of the fluctuating wind turbine.

The first (right) 12 and a second (left) 13 nodes change the orientation and fixing the position of the blades installed on the first (lower) rod 5 symmetrically on both sides of the vertical shaft 4.

The nodes change the orientation of the blades 12 and 13 have the same construction and operate in very difficult conditions is a single. They contain a plane-parallel plate 30 fixedly connected with the two sides of the vertical shaft 4. Through the plate passes freely the first rod 5. Each node 12 (13) contains the dog 31, interacting with the corresponding locking ring 32 (33)fixedly mounted on the first rod 5. In addition, the first and second nodes change the orientation of the blades contain the appropriate spring twist 28 and 29 and the stars 24 and 25 mounted on the carriers and third 26 and fourth 27 overrunning respectively. And overrunning clutches are in the grip in turns. Hub overrunning clutches 26 and 27 are free to turn on the first rod 5 and interact with the first 28 and second 29 spring twist, respectively. The root ends of these springs are connected with the respective locking rings 32 and 33. The locking rings have two hrapovic protrusion located on diametrically opposite sides. When the locking rings 32 and 33 fixed on the rod 5 so that the ratchet projections have been shifted by an angle relative to each other by 90. Ratchet protrusions of the locking rings 32 and 33 in turn includes a coupling with a respective spring-loaded dogs 31 and fixed angular position after each rotation of the rod and 90 around its own axis.

The first 24 and second 25 stars, still set the military on the third clips 26 and 27 fourth overrunning, interact with the corresponding segment of the chains 35 and 36. Segment chain is stationary on pavaroti platform 3 along a circular segment, occupying 90 with two diametrically opposite sides.

Given in figure 2 the direction of the wind under his influence on the right of the blade 8 a vertical shaft 4 is rotated counterclockwise by 90. The clutch includes a third overrunning clutch 26. First star 24 mounted on the ferrule of the third overrunning clutch, interacts with the first segment of the chain 35. In the first spring 28 is twisted by 90 and accumulates energy. After rotation of the shaft 4 by 90 is the interaction of the pawl 31 with the stop 34. In the dog out of the clutch ratchet with protrusion of the first retainer ring 32, and then twisted the first spring 28 rotates the first fixed ring 32 and an associated first rod 5 clockwise by 90. At the end of this turn ratchet protrusion of the second retainer ring 33 is included in the coupling with a corresponding dog 31 and locks the angular position of the blades 8 and 9. Now in a vertical position be the left of the blade 9. Under the influence of wind on the left of the blade vertical shaft is rotated in the opposite direction - clockwise. Now the clutch is the fourth overrunning clutch 27. Vtorayatisya 25, mounted on the yoke fourth overrunning clutch, included in the coupling with the second segment of the chain 36 and twists the second spring 29 90 clockwise. The second spring should have left spin, and the first right. At this time, the third overrunning clutch 26 out of the clutch and the first star 24 rotates idle counterclockwise and returns to its original position. After twisting the second spring 90 dog second node 13 faces the corresponding stop 34. When the output of the second pawl of the clutch ratchet with protrusion of the second retainer ring 33 is twisted second spring 29 rotates the second ring 33 and an associated first rod 5 by 90 clockwise, and then fixing the angular position of the rod 5 using the ratchet projection of the first locking ring 32, which is coupling with the first dog 31.

Thus, the sequential interaction of the nodes change the orientation and fixing the position of the blades 12 and 13 with the corresponding segment of the chains 35 and 36 causes rotation of the first rod in a clockwise direction, and the vertical oscillation of the shaft 4 in the direction in the range of 90. Moreover, fluctuations occur within an angle of 45 from the position where the torque on a shaft maximum. The maximum torque corresponds to a perpendicular position plose the spine of the blade to the direction of the wind.

The average torque on the shaft when the boom oscillation within 45 0 9PSR, where P is the power of the wind, S - area of the blades, R is the distance from the axis of the vertical shaft to the center of the blade.

Compared with the prototype, the torque on the shaft in coliblue the wind turbine in case of equality of P, R and S increases 3 times. Thus, significantly increases the efficiency of the turbine and reduces its consumption and cost. To change the orientation of the rods 5-7 in the measurement of wind direction can be used flat vane, the lever 38 are rigidly connected with the turntable 3 in the radial direction.

To automatically adjust the speed of rotation of the output shaft 20 of a wind turbine it is necessary to use a conical or pyramidal vane 37. The vane should be truncated. The wind pressure on the lateral surface of a truncated vane causes it to move along the horizontal arm 38. The amount of linear movement of the vane is set using restrictive rings 39 and 40. Parameters of the third spring 42 (length, stiffness) are determined by wind speed, within the changes which synchronize the speed of rotation of the output shaft 20 of a wind turbine. To adjust the torque generated under the influence of wind on the flat of the blade, use the synchronization host-based maintains the processes in the angular position of the blades (see 3), or the node synchronization, based on the regulation of the length of the arm (see figure 4).

In the first version of node synchronization (figure 3) adjusting the torque of the output shaft by changing the effective area of the blades - S. With increasing wind speed, the effective area of the blades should be reduced.

In the second version of the site (figure 4) to adjust the torque of the vertical shaft is used to change the length of the arm, as well as the effective area of the blades S, the greater the wind speed, i.e. the pressure P, the smaller should be the length of the lever R and the effective area of the blades S.

The design of the site presented in figure 3, the change in the effective area of the blades S is achieved by changing the angle of the plane of the blades relative to the horizontal and vertical directions. Changing the angle of the blades is carried out by measuring the angular position of the pawl 31. For this purpose, the design of the pawl complicated. Head first sliding pawl 43 has an arched shape and moves in a circle in the range from 0 to 45 deg. When wind is weak, when the conical vane is pressed under the influence of spring 42 to the bounding ring 39, the cable 41 is in a free state. Under the influence of the fourth spring 45 mounted in the inner cavity of the hollow lever pawl 44, the head sliding soba is key 43 is in its extreme upper position. In this position the dog right blades 8 accept vertical and left 9 - horizontal position.

With increasing wind speed conical vane 37 is moved along the horizontal lever 38 and pulls the rope 41, thrown through the block 46. The end of the rope is connected with a sliding dog 43. The crown dog goes and takes a new angular position. The higher the wind speed, the lower head of the dog. Ratchet tabs of the locking ring 32, and the associated steady through the first rod 5 blades 8 and 9, a new angular position relative to the vertical and the horizontal. The effective area of the right-wing blades 8, which creates a positive moment on the shaft 4, is reduced. Left blades 9 mounted at an angle to the horizontal, creating a negative moment on the shaft. This leads to a reduction in the rate of rotation of the vertical shaft 4, and hence the output shaft 20 of a wind turbine.

The fourth spring 45 provides the pressing tip retractable dog to the profile surface of the locking ring 32. Spring pawl 47 of the right node changes the orientation is left hand twist and left-node - right. The block 46 is installed coaxially with the axis of oscillation of dogs running spring pawl 47.

The lever pawl 44 in the end of the angular oscillations of the rod 5 interacts with rela is Estulin emphasis 34, then twisted the spring 28 (29) rotates the locking ring 32 (33) and an associated rod 5 by 90 clockwise. In this case, the segment chain must take a large angle of about 120. Instead segmental circuits can be used equidistant notches or holes. Active blades 8 are in a passive horizontal position, and passive 9 - vertical active position, followed by reverse movement of the bar with more low angular velocity. Thus, there is a stabilization of the rotation speed of the output shaft of a wind turbine.

The principle of operation of the node synchronization by adjusting the length of the lever R, the design of which is presented in figure 4, consists in the following. On the first turntable 3 hinge set, the second rotary platform 48 with the possibility of relative rotation between 0 and 90. The fifth spring 49 mounted between the rotating platform, works on promotion. When wind is weak, when the third rope 50 is in a free state, the spring 49 rotates the upper platform in the initial (zero) position. This position corresponds to the maximum lever R, when the lever vane perpendicular to the rod. With increasing wind speed conical vane pulls the third cable 50, thrown through the block 51 and held out OK is agnosti second pavaroti platform 48, 90. In the upper platform 48 is deployed relative to the lower platform 3 in a counterclockwise direction. The higher the wind speed, the greater the angle of rotation of the upper platform, on which are fixed segment circuits 35, 36 and the stops 34. When exceeding the wind speed is above the allowed value, the upper platform turns 90 and rod are guided along the arm 38 of the conical vane. When this occurs, the braking of the wind turbine, as the plane right 8 and left 9 of the blades coincide with the direction of the wind. The operating range of the wind speed is set by selection of the parameters of the conical vane and spring 42, 49.

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.
