Abstract

The kionas wind turbine consists of removable cooperating stages where each stage is an autonomous wind turbine. The tapered-conical sections (1) (2) or (1.1) (2.1) and the stator or adjustable guide vanes (3) or (3.1) compress and direct air to the blades of the rotor (14) or (15.1), wherein each rotor (14) (15) (15.1) has its own generator. The stage can place within it further rotors (15) which rotate the vortex created by the rotor (14). Stages are intercommunicating and positively interact with the vortex created by the rotors (14) (15.1), increasing efficiency at all levels whenever a new one is added. In order to protect the kionas wind turbine from high winds, the rotor (14) is placed between the turbine and the base (7) in a movement and concealment mechanism thereof with pistons (10), so that the air flow passes the stages without resistance. In addition, the movement and concealment mechanism has a height adjustment of the base (7) to provide a partial breach of the rotor (14) at low intensity winds.

Description

Kionas Wind Turbine

The invention relates to a vertical axis wind turbine on composed of detachable modules where each stage is an autonomous wind turbine, the stages are positioned perpendicular to each other and consist of the stator-fixed part and the rotating part.

The vertical axis wind turbines are used for power generation through the power of wind. Consisting of the generator, the support base of the generator and the rotor. In the large dimensions of the vertical axis wind turbines, the rotor also has a support base. They use various kinds of rotors and exploit the power of the wind regardless of its direction, without the need to adjust the cursor on each switch of the wind's direction. The rotors used by the vertical axis wind turbines operate aerodynamically or through the wind's resistance. They present disadvantages such as low yield ratio due to low rotation speed, high starting torque, difficulty in the maintenance of certain mechanical parts such as changing the roller bearings, if they are damaged or loose then they are liable to cause destruction because their fins are exposed. The biggest problem wind turbines generally have is the way to deal with high winds, where the largest propart of these simply brakes the shaft of the generator. Some vertical axis turbines use additional bearings because the wheel needs a separate base support, resulting in more friction and therefore less gain. Another drawback is the problem of aesthetics, since the rotor is exposed, along with the negative effects they cause to the biodiversity due to the exposed rotor.

The present invention relates to a vertical axis wind turbine composed of stages. All stages of the kionas are autonomous and wind up of the stator and the rotating part. The stator part is composed of tapered sections (1 ) (2), the guide vanes (3), the cylindrical sections (4) (5), the ribs (6) and the tube (9). The guide vanes (3) are stator or adjustable, meaning they can regulate their inclination to direct air to the blades of the rotor (14).

The rotatable part of the stage is composed of the rotor (14) or the rotors (14) (15) in the cases a stage-stage has more than one, the generator or the generators and the base of the generator support which can be fixed (8) or adjusted (7). The stage may have more than one rotors, wherein each rotor has its own separate generator and holder (7) or (8).

The wind turbine kionas produces energy when the rotor (14) of the stage is set in rotation by the air force. The air strikes the body of each stage of the kionas and is compressed by the tapered sections (1 ) (2), increases its speed and is directed to the blades of the rotor (14) of the guide vanes (3). In this manner of manufacturing, the rotor (14) is enclosed by the stator part of the kionas. The guide vanes (3) direct the air to the blades of the rotor (14), resulting in rotation at one direction and without need for kionas orientation in each rotation of the wind direction. The blades of the rotor (14) are inclined so as when rotating, they entrain air to put in rotation and steer it in another stage rotor when the wind kionas comprises of a plurality of stages. Each stage is vertically opened to the diameter of the cones (1 ) (2) communicating to each other and interacting with the amount of air which entrains the rotors (14). With the technique of communicating stages, the rotor (14) of each stage receives greater amount of air to the fins and the batch size is increased by the increment of the number of stages in the kionas. Each time a stage is added in the kionas with a crowd of stages the result is an increase of power at all levels of the kionas due to the effect of the interaction. For the creation of the effect of the interaction of the rotors (14) of the kionas at all levels, their fins should have the same direction of rotation and the same inclination.

The gradient has the ability of placing extra rotors (15) for harnessing the power of the amount of air escaping from the vertical opening of the stage due to the inclination of the rotor blades (14) that creates the interaction. In the stage the rotor (14) is affected and is set in rotation directly from the air, while the rotor (15) rotates by the vortex created by the rotor (14).

For better aerodynamics, a tube is placed in the space the rotor (14) and the mounted generator are (9). The tube (9) causes the entire amount of air to be directed to the blades of the rotor (14) and may also be internally mounted with the generators of the rotors (14) ( 5).

To protect the kionas from strong winds, the rotor (14) through the generator is placed in a removable base (7). The base (7) is able to adjust the amount of the resulting adjustment of the height of the rotor (14) to have partial or zero influence from the air. A negative influence to the rotor (14) is for its protection but also for the generator's, which is connected to conditions where the wind is very strong. By hiding the rotor (14), the air does not find resistance in the body and crosses the stage with ease. When the wind is not strong enough, the base is adjusted to a suitable height so that a part of the rotor (14) coming into contact with the air is producing energy while it and the connected generator are being protected.

The movement of the base (7) of the rotor (14) is made with a device carrying plungers (10). The pistons (10) are connected at one end to the base (7) of the generator and the other end of the stator part of the kionas in the cylinder (4) or (5). As the pistons (10) make a reciprocating motion, they force the base (7) in a vertical motion.

The stator part of the stage can also be made with tapered sections (1.1 ) (2.1 ) have different size, have the same mounting direction and connected to the guide vanes (3.1 ) which are adjustable angle relative to the manufacturing center of the kionas. The blades of the rotor (15.1 ) in this construction are inclined stator or adjustable, and have the same function as the previous design. The air compressed by the guide vanes (3.1 ) and the cone (1.1 ) is forced to follow the surface of the cone (1.1 ) so that it is directed to the blades of the rotor ( 5.1 ). The construction of the kionas with the cones (1.1 ) (2.1 ) has the result that the rotor (1/15) is not visible externally. The stage disposed vertically in another stage, conceals the cone (2.1 ), its inner cone (1.1 ) in the stage disposed and thusly cones are not visible (2.1 ) in a kionas with a plurality of stages but only in the first step. The placement of the cones (2.1 ) inside the cones (1.1 ) in another stage makes the structure robust because it does not allow it to move and detach.

Benefits of kionas turbines

Each stage of the kionas can be connected to supply a separate electrical circuit. s Protection of the rotor (14), of the generator and generally the whole structure of the kionas with the base movement mechanism (7) in case of very strong winds. Adjusting the height of the base (7) has a partial consequence of stroking the rotor (14) from the air, resulting in electricity production even in high winds. High aesthetic, since the rotating parts of the structure of the kionas are not visible and as such, the structure appears compact.

In case a stage of the kionas set is off for some reason, the others still operate normally.

It provides high operational safety because the rotating parts are enclosed by the stator part, and in case a piece of the rotating part is detached, it cannot be hurled outside of the stator part.

The kionas has a safer approach because the rotating parts are surrounded by the stator part of the structure of the kionas.

Stages can be added or removed from the turbine kionas in case the power production needs increasing or reduction.

With the addition of stages, the pillar strength increases at all levels constituting the kionas, due to the interaction created between stages.

Easy to transport and maintain because the kionas consists of stages, where each stage is disassembled into smaller sections.

Low acoustic noise because the rotating parts are surrounded by the stator part of the structure so that the sound is not broadcasted. The stage uses a compact rotor as the air increases the velocity of the conical sections (1 ) (2) or (1.1 ), resulting in lower cost thereof.

Description of the invention with reference to the accompanying figures.

Figure 1 shows the movement of the base (7), of the rotor (14) of each stage. The figure is a side view and shows the movement it makes by moving the base (7) of the generator up and down accordingly. By moving the base (7) of the generator the rotor is moved (14), hiding the inside of the stage so as not to be affected by the incoming air and thus be protected. The movement mechanism of the base (7) consists of pistons (10) which may be of all kinds such as electric, oil or air. The movement mechanism has the ability of adjusting the height of the base (7) so that the rotor (14) can have a partial influence of the incoming air. In figure 4 the reciprocating motion of the pistons is shown (10) and the piece of the connection points (1 1 ) (12) of the pistons to the cylinder (5) and the base (7) of the generator. The pistons (10) are supported at these points (11 ) (12) through a small shaft (13) to allow their movement. It can be distinguished that joints (11 ) (12) of the piston with the base (7) of the generator and the cylinder (5) are at the same level to prevent the opposite movement downward.

Figure 2 shows the movement mechanism of the base (7) in a bottom view. All the segments consisting it are distinguished; the three points (1 1 ) connecting the cylinder and the three points (12) connecting the base (7) of the generator. The three points (1 1 ) and three points (12) are respectively equally spaced so that the simultaneous reciprocating motion of the pistons (10) can move the base (7) of the generator. Figure 3 shows the stage's side view, distinguishing the tapered sections (1 ) (2) the guide vanes (3) and a small part of the blades of the rotor (14).

Figure 4 shows the stage's bottom view face. Visible are the conical section (2), the rotor (14), the cylinder (5) and the ribs (6) which connect and support the cone (2) with the cylinder (5). Figure 5 shows the stage from a top view distinguished conical section (1 ), the rotor (14), the cylinder (4) and ribs (6) which connect and support the tapered section (1 ) with the roller (4).

Figure 6 shows the stage in a vertical incision wherein shown are the guide vanes (3), the two conical sections (1 ) (2), the two rollers (4) (5), the ribs (6), the rotor (14) and one piston (10) of the base moving mechanism (7) connected to the cylinder (5) at the point (11 ) inside the stator part of the stage.

Figure 7 shows the kionas wind turbine with three stages in a side view. The rotors (14) of all levels have moved within the stage to keep the stages from being stricken from the air if it is very strong.

Figure 8 shows Figure 7 in a vertical incision, distinguishing the point moving the rotors (14) of each stage when there are strong winds so that they can be protected. The movement of each rotor (14) is made with the base movement mechanisms (7) each stage has. The air flow passes through the stages with ease after not finding resistance in the body of the rotors. The rotor (14) inside the stage moves and is enclosed by the conical section (2) and the cylinder (5) so as not to be affected by the influence of the incoming air.

Figure 9 shows the kionas wind turbine with three stages in a side view, with the rotors (14) distinguished in 50% of their height with the movement of the base mechanisms (7). When there are moderately strong winds, the movement mechanism is able to adjust the height of the base (7) with the result of the height of the rotor (14) so that the rotor (14) of each stage to have partial influence of the incoming air and operate safely, producing energy through the generator it connected to.

Figure 10 shows in vertical incision in Figure 9 to illustrate the adjustment of the height of the rotor (14) of each stage of the turbine kionas. In Figure 9 the rotors (14) are affected by the incoming air to 50% of their height so they can produce energy but the possible incoming air can penetrates the stages with ease.

Figure 1 1 shows in vertical incision in Figure 9 at an angle of the stator part of the kionas wind turbine with three stages. The area in which the stages are perpendicular open so that they can communicate and interact positively increasing their performance can be shown. In this space, the vortex is created by the rotation of the rotors (14), because their fins have a stator or adjustable tilt and thus entrain incoming air influencing them and direct it internally to another stage.

Figure 12 shows the kionas turbine in side view with ten stages, but uses 12 rotors. The additional two rotors (15) are not visible externally and are placed one on the first and one in the last stage. They rotate by the force of the vortex generated by ten fan blades (14) susceptible to the influence of the incoming air and placed in a fixed base (8) by means of the generator. Figure 13 shows figure 12 in vertical incision. The part in which the two rotors (15) are placed is shown, which is not directly affected by the influence of air, but rotated by the vortex the ten fan blades generate (14), susceptible to the influence of the incoming air. The one rotor (15) is placed in the tenth stage, and is enclosed by the cylinder (4) associated with the tapered section (1 ). The other rotor (15) is positioned in the first stage and is enclosed by the cylinder (5) connected to the conical section (2). In this figure it is also shown that the movement of the base mechanism (7) can be placed in both cylindrical sections (5) or (4) as in the first and last stage respectively.

Figure 14 shows Figure 13 at an angle showing the inclination of all of the rotor blades (14) and (15) of the kionas wind turbine. The single ensemble of all ten stages is distinguished internally where the vortex is generated by the rotation of the rotors (14) so that the stages communicate and interact positively, increasing their performance. The two rotors (15) not affected by the influence of the incoming air increase the overall efficiency of the wind turbine because they exploit the power of the vortex which would be lost if it was external. The rotor

(15) is placed in the first stage because the turbine generating the ten rotors (14) affected by the incoming air is directed from the top to down internal stages and thus takes advantage of the power otherwise lost. The rotor (15) in the tenth stage exploits the vortex created by the turbine to the direction it has because it sucks air from top downwards.

Figure 15 shows the stage with different size cones (1.1 ) (2.1 ) in the top view angle. Distinguished are the fins (3.1 ), the cones (1.1 ) (2.1 ), the flange (16) and the cylinder (5.1 ). Even the void from which the air flow enters and affects the blades of the rotor is shown (15.1 ). This void is generated because the small diameter of the large cone (1.1 ) has a smaller dimension than the minor diameter of the flange (16). The large diameter of the flange

(16) is connected to the large diameter of the small cone (2.1 ) and the small diameter of the flange (16) is connected with the cylinder (5.1 ). In the cylinder (5.1 ) are connecting the small diameter of the small cone (2. ) and the small diameter of the flange (16).

Figure 16 shows the stage of figure 15 on a bottom angle. Distinguishing the cones (1.1) (2.1 ), the guide vanes (3.1 ), the cylinder (5.1 ), the fixed base (8.1 ) of the generator and the fan (15.1 ). The blades of the rotor (15.1 ) have a stator or adjustable inclination to be affected by the incoming air. The inclination of the rotor blades (15.1 ) of each step is to lure the incoming air and direct it to the rotor blades (15.1) in another stage, generating a vortex.

Figure 17 shows the step of Figure 15 in top view. Distinguishing the part of the rotor (15.1 ), which is affected by the vortex created by the rotors (15.1 ) of the stages as they rotate. The remaining part of the rotor (15.1 ) is affected by the incoming air and is hidden by the large surface of the cone (1.1 ).

Figure 18 shows the stage of Figure 15 in side view with vertical stage. The point is shown where the rotor is placed (15.1 ) as well as the angle the flow of the air intake which affects the fan (15.1 ) because it follows the surface of the large conical section (1.1 ). In this stage can be seen that the large cone (1.1 ) compresses the vortex created by the rotors (15.1 ) with its form, increasing its speed. Figure 19 shows the kionas wind turbine with three stages in elevation. The rotors (15.1 ) are not visible from the outside but the small cones (2.1 ) of the two stages that were added are not visible because they are arranged inside the large cone (1.1 ) of the stage they are placed in.

Figure 20 shows Figure 19 at an angle as to illustrate the gap in which the air flow enters and is directed to the blades of the rotor (15.1 ). The inlet of air flow is directed to the blades of the rotor (15.1 ) with a slope at each stage of the shape possessed by the large conical section (1.1 ) as it is forced to follow the surface which has this gradient.

Figure 21 shows Figure 19 in vertical incision. It shows how the stages are placed perpendicularly between them along with the part where the small cone is placed (2.1 ) in each stage inside the large cone (1.1 ) in the stage placed.

Figure 22 shows the kionas wind turbine with five stages in vertical incision at an angle without the rotors (15.1 ). In it are shown the positioning and support of the fixed base (8.1 ) in the cylinder (5.1 ) at three points of each stage. At the base (8.1 ) the generator is connected to its axis, via a coupling, the rotor is connected (15.1 ). Figure 44 shows the vertical opening in the diameter of the cones (1.1 ) (2.1 ) each stage has so that the stages can communicate and interact positively and create an ensemble.

Figure 23 shows a vertical stage of the kionas wind turbine wherein the tubes (9) are distinguished. The tubes (9) provide optimal aerodynamic in the space where they are placed, since the generators of the rotors are placed in the interior position (14). The tubes (9) are also forcing the entire volume of the incoming air to be directed to the blades of the rotors (14) (15) without escaping externally from the stages.
