Definitions

• the present invention relates to a device for capturing wind power and transforming it into pneumatic or electrical energy.
• wind turbines Devices designed to capture and transform the power of the wind, called wind turbines, have been used for centuries to pump water or do any other similar work. Efforts have been made to improve the efficiency of wind turbines without obtaining effective results.
• the power produced by a conventional wind turbine is directly proportional to the square of the diameter of the circle described by the rotation of the ends of the blades and to the cube of the wind speed. Furthermore, the further the point of application of the wind force is from the axis, the more the turbine is rotated, but the larger the diameter, the lower the speed of rotation.
• the object of the present invention is to remedy these drawbacks and relates to a wind motor intended to drive a compressor, and; combining all the advantages that can be obtained from a large diameter wind turbine without the disadvantages.
• the wind motor according to the invention is in the form of a turbine comprising two large diameter rotors provided with small blades integral with the same axis arranged in a cylindrical chamber or tunnel, means being provided for directing the air towards the blades rotors, and then channel it outwards, the assembly being surrounded by a second annular chamber intended to heat the air during its passage between the two rotors.
• a compressor or any other device (dynamo, pump, etc.), the whole being arranged in a fairing intended to facilitate the flow of the 'air.
• the assembly is mounted on a support pivoting 360 °, inside which is provided a descent of compressed air, in the example shown, but this pipe can be replaced by an electric cable in the case where a dynamo is driven, by the device.
• Figure 1 is a perspective view of the turbine according to the invention.
• Figure 2 is a sectional view of the turbine.
• the device according to the invention consists of a cylindrical chamber or tunnel 1 inside which is disposed a horizontal axis 2, carried by rolling bearings 3, and supported by three streamlined and inclined spacers 4, arranged at 120 °, at each end of the tunnel; on the horizontal axis 2, two rotors are mounted: an inlet rotor 5 and an outlet rotor 6.
• These rotors are constituted by a disc 7 of large diameter at the periphery of which are blades 8, profiled.
• These vanes 8 are mounted by means of a bushing in orifices provided at the periphery of the disc 7, with the possibility of adjusting their angle of inclination.
• a fairing 9 forming a convergent intended to channel the air towards the blades of the rotor 5.
• the fairing must have on the air inlet side at least a diameter twice that of the rotor
• the disc 7, advantageously carries on the outer face a cone of attack 7a, intended to cooperate with the convergent 9, to direct the air on the blades 8 alone.
• a second fairing 10 forming a diverging portion.
• a nacelle 11 carried by three spacers fairings 12, so as not to disturb the flow of air. These spacers are also arranged at 120 ° from each other.
• the nacelle 11 forms a leak cone 11a, facilitating the relaxation of the air.
• an air compressor 13 whose axis 14, is connected to axis 2, of the wind turbine by means of a grooved rod 15, allowing a certain play between said axes.
• the compressed air outlet pipe 16 of the compressor 13 is judiciously placed in one of the spacers 12, to exit under the tunnel 1.
• annular chamber 17 is provided, arranged over the entire length of the tunnel 1. On the end of this chamber 17, located on the side of the fairing 9, are provided small fins 18 allowing the entry of air into this room.
• This air will be heated by the compressed air from the pipe 16, passing through said chamber 17; this heat will have the effect on the one hand of causing an expansion of the air located between the inlet rotor 5 and the outlet rotor 6, causing it to be ejected at a higher speed, and on the other hand, avoiding the icing of the whole in cold weather.
• the assembly is mounted on a support 19, constituted by a vertical tube 20, inside which is mounted a rolling bearing 21, in which the end of a mast 22 will come, for example, so as to allow the whole rotate 360 °.
• the compressed air line 16 will descend inside the mast 22, an O-ring 23 being provided at the upper end of said mast to allow rotation of the assembly, and the compressed air is directed to the ground towards a tank storage (not shown).
• the operation of the wind turbine is simple.
• the air enters the converging formed by the fairing 9, it is concentrated on the blades 8 of the rotor 5; its speed therefore increases and the air then passes through the blades of the rotor 5 causing it to rotate at a speed proportional to that of the flow.
• the air then passes through the tunnel 1 where it heats up slightly, which has the effect of slightly increasing its speed. It then passes through the vanes 8 of the outlet rotor 6, and it is then ejected and expands outwards through the divergent 10.
• the rotation of the rotors causes the compressor 13 to drive through the axis 2, the grooved rod 15, and the axis 14.
• the compressed air produced passes through the tube 16, which passes through the annular chamber 17, heating the the air there, and is directed to the storage tank where it can be used as needed.
• the air flow takes place in the turbine according to the invention without any turbulence, the spacers being all faired.
• the turbine according to the invention can be made of metal, or plastic, in particular fairings, and is of very economical cost, allowing its use in poor countries.
• the use of this wind turbine with a compressor allows easy and long-term compressed air storage, but of course, the compressor could be replaced by any other device, in particular an electric generator.
