Definitions

  • the device relates to wind energy.
  • a device for receiving wind energy with a vertical axis of rotation IONNINA FACTORY: KOSMIRA, ATHENS: NIKISl, SIDAGMA, E-mail: info@air-sun.gr, which contains a rotor with a vertical axis of rotation and a wind flow divider made in the form of a plate in the form of a right-angled triangle, the hypotenuse of which is firmly fixed outside the rotor.
  • the divider partially changes the intensity of the wind flow and more or less evenly distributes the wind flow between the concave and convex surfaces of the rotor, due to which the rotor is rotated with a relatively equal molecular velocity.
  • the design drawback is that the triangular-shaped wind flow divider partially fulfills its function only in its wide part (at the base) and is completely useless in the region of the upper acute angle of the triangle.
  • the wind divider is not able to completely divert the wind flow from the convex surface of the rotor and, therefore, eliminate the inhibitory effect of the wind flow resulting from this.
  • a wind turbine is also known (Patent R U N # 2384732 C 1), in which two rotors with a vertical axis of rotation are located on the sides of the airship-like fairing, where the concave turbine blades protrude symmetrically from the outside of the fairing.
  • the latter on the one hand, shields the convex parts of the blades from the oncoming wind stream, and on the other hand, acts as a weather vane to orient the entire device towards the wind stream.
  • a wind energy system is also known (WO 2012/147108, PCT / IN 2012/0003217), which comprises a housing where two rotors with blades on the vertical axes are arranged to rotate in opposite directions, where the device body and rotor blades are located tangentially.
  • the prototype of the alleged invention is the "Rotor and device for receiving wind energy” (GE P 2015 6299 V), where two rotors with vertical axes of rotation are located in one housing, between the rotors in front and behind the wind flow divider is installed.
  • the disadvantage of this device is that its body performs mainly the function of connecting and locating the rotors and the divider of the wind flow, but the body itself is little involved in actively enhancing the wind flow falling into the zone of the device.
  • the aim of the proposed invention is the creation of such a device where its body will provide active interaction not only with the concave, but also the convex surfaces of the rotor blades and the wind flow divider to more fully absorb wind energy and increase the overall efficiency of the device.
  • the technical result of the device is a significant increase in its effectiveness.
  • the divider directs the entire wind flow to the concave surfaces of the rotor blades, while at the same time it covers the convex surfaces of the rotor blades.
  • the wind flow entering the device’s casing is in a limited space created by the walls of the casing covering the entire front half of the rotors, and the vertical walls of the casing are tangential to the rotors, the wind flow is narrowed and, according to Bernoulli’s law, respectively , it accelerates and amplifies the torque of the rotors.
  • the accelerated wind flow continues to move in the direction coinciding with the direction of rotation of the rotors , which also enhances the power of their rotation.
  • the enhanced wind flow that enters between the horizontal walls of the body and the outer and inner halves of the end parts of the rotors.
  • the reinforced wind flow entering the outer halves of the end parts of the rotors in the direction coincides with the direction of rotation of the rotors and enhances this rotation.
  • the wind flow creates a vacuum from the rear inner side of the rotors, which are covered by a wind flow divider, and sucks the air out of this space, which coincides with the direction of rotation of the rotors in this place and also contributes to strengthening rotor rotation.
  • the described device for receiving wind energy not only fully orientates the impact of the wind flow on the active, concave surfaces of the rotor blades, not only completely eliminates the impact of the wind flow on the convex surfaces of the rotor blades (and their inhibitory effect), not only enhances the flow wind falling into the range of the device’s body, but even in the closed area of the convex surfaces of the rotor blades provides active suction of air, which creates additional torque, with falling in the direction of rotation of the rotors.
  • the figure 1 presents a cross section of the device
  • the figure 2 presents a front view of the device
  • the figure 3 presents a side view of the device.
  • a device for receiving wind energy comprises a quadrangular housing 1, a wind flow divider 2 in the center of the housing 1, two wing rotors 3 having the ability to rotate in opposite directions on the vertical axes; the housing 1 on all four sides covers the front half of the rotors 3, and the rear wall of the housing 1 covers 50-85% of the rear half of the rotors 3; while the lateral (vertical) walls 4 of the housing 1 relative to the front half of the rotors 3 are located tangentially, while the rear 5 of the vertical walls 4 of the housing 1 are rounded parallel to the rotors 3, while the inner surfaces of the horizontal upper, lower 7 and vertical 9 walls 4 buildings 1 are convex, and the outer walls 8 and 10 are flat.
  • a device for receiving wind energy works as follows. When the wind flow enters the front of the device, the wind flow is in a limited space that is created between the housing 1 and the wind flow divider 2, located in the center between the rotors 3. Due to this, the wind flow is directed to the concave surfaces of the blades of the rotors 3 and the wind flow is excluded on the convex surfaces of the rotor blades 3, so the energy of the wind flow creates only the torque of the rotors 3 and does not slow down their rotation.
  • the housing 1 of the device in the front part covers the entire front half of the rotors 3, and the vertical walls 4 with respect to the front half of the rotors 3 are tangent, the wind flow is narrowed and, therefore, according to Bernoulli’s law, it accelerates, which contributes to accelerating the rotation of the rotors 3.
  • the accelerated wind flow changes its rectilinear direction, is rounded inward, which coincides with the direction of rotation of the rotors 3 and enhances their rotation power.
  • the direction of the accelerated wind flow coincides with the direction of rotation of the rotors 3 and enhances the power of their rotation.
  • the accelerated wind flow acts as a vacuum, sucking air from the convex surfaces of the blades of the rotors 3, covered by a divider of the wind flow 2, which actually creates additional torque that coincides in the direction of rotation of the rotors 3.
  • the described device body 1 and the wind flow divider 2 consistently ensure that in all phases of the movement of the rotors 3 they direct the wind flow only to the active, concave surfaces of the rotor blades 3, divert the wind flow from the passive convex surfaces of the rotor blades 3, maximize the flow of wind falling into the range of the device, which generally significantly increases the efficiency of the device.
