Abstract

The sprockets with irreversible clutch (10) and (11) are alternately activated clockwise when the lever arms (8) and (9) pull the chain (12) and (13) in turn. These lever arms (8) and (9) rock with the mast (4) which is pushed when the blades (1) of the rotor are vertical when turning. Then the irreversible clutch of the chain wheel (10) is activated and the shaft (15) and the flywheel (D) rotate with it. When the mast returns by the force of gravity of the counterweight (5) when the blades are horizontal (there is no sail effect anymore) the irreversible coupling of the sprocket wheel (11) is activated. The flywheel (D) spins with the gears when each irreversible clutch is activated individually and in turn. The flywheel provides uniform rotational movement to the generator (21) through the drive belt (16). The rudder (22) orientates the machine with respect to the wind and the fixed anchor (27) serves as an oriental center point.

Description

ELECTRIC GENERATOR WITH WIND MOTOR OF SWING AND TELESCOPIC MAST AND WITH A SAIL ROTOR

This invention is directly related to the conversion of wind energy into electrical energy with the aid of a powerful Wind motor and with the aid of a mechanism that converts a rocking movement into a uniform rotating movement. We will name the Wind Engine as a Wind Engine of Swinging Telescopic Mast and with a Sail Rotor. The abbreviation (in Spanish) of the name of this Wind Engine is MEMTOR-V and that means: Motor Eólico con Mâstil Telescópico Oscilante y Rotor-Vela. So, this is an Electric Generator with a completely new type of Wind Motor (MEMTOR-V) that is very powerful and with a transmission mechanism that converts the swinging movement of a mast into a uniform rotary movement. It is a completely new concept related to wind energy.

The essential problem of converting wind energy into electrical energy is that current methods are not efficient and expensive. It also happens with modern wind turbines.

During the search of the state of the art I did not find a wind machine that works with such a Wind engine as the MEMTOR-V. All existing conventional rotors sit and rest on a fully fixed mast and this mast absorbs much of the force of the wind without really using it and the moment of the force the blades exert against the central axis of a conventional rotor very small when compared to pushing the wind against this fixed mast. In a MEMTOR-V an ordinary fixed mast "becomes" a giant, rocking and double lever arm; and a conventional inefficient rotor "turns" into a rotating wide sail that swings with this giant swinging Archimedes lever arm.

In this way the wind, in turn, pushes the entire surface of a rotating, wide and compact sail and this sail transfers the power to a mast that is not stuck and can swing on its support shaft. This mast never falls because of a heavy counterweight has that is stuck, on the other lever arm, that swings under the support axis or support point. The swinging mast can be extended because it is telescopic; in this way one achieves the desired length and to ensure that the wind exerts the desired force. In this way a complete transformation of old and classical components with certain technical characteristics and a certain way of working takes place in a compact and efficient mechanism with elements that are totally different have technical characteristics and ways of working. The Electric Generator with MEMTOR-V also has a mechanism to convert the oscillating movement into a smooth rotating movement. In this way I achieve the purpose of this invention: inventing a mechanical method that is very efficient is to convert wind energy into electrical energy.

ADVANTAGES: 1 - This power group has a very large power thanks to the power of the MEMTOR-V. The mast can always be extended and the sail rotor catches a lot of wind with its entire surface. So the combination of these two elements creates a giant and double Archimedes lever arm that is put to work by pushing a large volume of moving wind that gets by the sail rotor.

2 - The construction and maintenance of an electric generator with a MEMTOR-V is much cheaper than modern wind turbines because these wind turbines are usually made with components that consist of heavy and expensive parts (very high, on top of a tower). By the way, the swinging mast and the sail rotor can be lowered as it happens with a normal crane arm and with the mast of the MEMTOR-V itself as a crane arm. If there is strong wind the mast can be pulled out together with the sail rotor and brought down to the ground.

3 - These Electric Generators with MEMTOR-V can be manufactured in all dimensions.

4 - Can also be manufactured to work on water and on solid ground.

5 - Work slowly without noise and are clearly visible by birds.

8 - Small sizes are also very efficient and ideal to provide sufficient electricity for homes.

9 - They do not use much space both on the ground and in the air. Description of the drawings

Figure 2: - blades (1) - axle (2) - mast (4) or rocking lever - central axis (SP) of the swing - counterweight (5) - starting position (a): the moment when the blades and the mast ( 4) be completely vertical during the rotation of the blades.

- position (b): halfway through the moment of the fluctuation; the mast is in the plane (- x; + y) and the counterweight (5) is in the (+ x; - y) plane; the blades (1) no longer have the full vertical position at this time of their rotation, counterclockwise.

- position (c): the end of the counter-clockwise movement with respect to the axis (SP); the blades (1) of the sail rotor have an almost horizontal position and the counterweight (5) sits at the highest point on the right side with respect to the (SP) axis; the gravity of the counterweight (5) starts to become more efficient than the sail effect because the blades are almost in a horizontal position.

- position (d): the moment when the clockwise swing has already begun.

- position (e): the mast (4) has a vertical position again but this time, the blades of the sail rotor are completely horizontal and the wind cannot push because there is no sailing effect anymore. The counterweight (5) is just below the (SP) axis during the clockwise swing.

- position (f): the mast (4) and the counterweight continue to fluctuate clockwise; the sail blades (1) begin to take a vertical position during rotation.

- position (g): end of the clockwise swing; the blades (1) have almost the vertical position and the counterweight (5) is at its highest point on the left-hand side with regard to the (SP) axle position (h): the mast and the counterweight have started to swing again against the hands of the clock; the sail effect has started again, the gravity and the sail effect now work together until the next position - repetition of position (a): the sail effect is at its maximum and the counterweight continues to fluctuate with impulse; the cycle repeats visibility every half tour of the sail rotor as long as the wind blows.

Operation of a Wind Engine of Rocking and Telescopic Mast and with a Sail Rotor; MEMTOR-V (with horizontal axis):

The MENTOR-V consists of the following more important components.

(Figure 1): the sail rotor with the blades (1); the axis of rotation (2) and the support (3); the telescopic mast (4); the support shaft (SP); the counterweight (5) with its lever arms (8) and (9) and the two columns (6) and (7).

The conditions (to have an optimal functioning of a Wind Engine of a Swinging and Telescopic Mast and with a Sail Rotor) are the following: Even if the telescopic mast is extended with its full length, the counterweight (5) must be heavy enough (or the springs must be strong enough) to keep the mast up. If not done so the mast (4) and the sail rotor can fall when they reach certain swing angle. It should also be done so because the counterweight has yet another important function. The direction of the wind should be so that the shaft (SP) crosses with 90 degrees (+ / -). The arc of the blades should not be sharp so that they are almost flat (the bend must be equivalent to the bend of a circle of an angle that is between 10 and 40 degrees) and so that the best sail effect is achieved and the rotor should not be as fast to twist . The optimum speed of the sail rotor is between 10 and 30 revolutions / minute.

A full cycle of the swing (back and forth) occurs during a half-turn of the sail rotor. The two blades together and simultaneously create the sail effect when they have reached the vertical position. In this case (Figure 2) the wind blows from right to left and the sail rotor rotates counterclockwise. The operation is as follows: - position (a): It is the starting position. The blades (1) together have the vertical position and the mast (4) with its counterweight (5) is also vertical. The wind blows from right to left and creates a good sailing effect on the blades that at the same time time begin to turn gently counterclockwise. As a result of the sail effect, the mast, together with the sail rotor and the counterweight (5), starts to swing counterclockwise with respect to the central axis (SP) of the swing. Thus two movements begin simultaneously: the swing of the mast and the rotation of the sail rotor that also participates in the swing.

- position (b): The blades (1) are no longer one hundred percent vertical because they continue to rotate, but they still catch the sail effect and the mast (4) further tilts counterclockwise. The counterweight (5), which is attached to the mast under the axle (SP), increases with its rotation with respect to axle (SP) and because of its heavy weight, it captures potential energy.

- position (c): The end of the anti-clockwise swing of the mast (4) - with sail rotor and the counterweight included - and this mast can no longer raise the counterweight (5); the sail effect is also reduced because the blades have almost reached the horizontal position.

- position (d): The mast (with the sail rotor and the counterweight always included) has already started the clockwise swing; the little sailing effect that still happens cannot stop the fall of the counterweight.

- position (e): During the clockwise swing the blades are completely horizontal and the counterweight is accelerated during its circular clockwise movement. The sail effect is at its minimum position (f): The counterweight is almost at its peak and starts to slow down. The blades are even more horizontal than vertical.

- position (g): The end of the clockwise swing; the counterweight cannot go higher; the blades have more a vertical position and the sailing effect starts again.

- position (h): The anti-clockwise fluctuation has started again. Two driving forces now work: that of the wind and that of the acceleration of the counterweight during its descent.

- repetition of position (a): It is the optimum moment for the operation of the MEMTOR-V; the blades have the maximum sailing effect and the counterweight is well accelerated.

- And so on

The operation of a mentor with a vertical sail rotor has a similar description to that of a horizontal sail rotor when one looks at the effect of the vertical sail rotor at a high position.

Operation of the double mechanical transmission (Figure 1):

This double mechanical transmission consists of: The extensions or the lever arms (8) and (9); the driving chains (12) and (13); the sprockets with irreversible couplings (10) and (11); the axis (15); the flywheel (D) and the drive belt (16).

The counterweight (5) and its lever arms (8) and (9) swing along with the telescopic mast (4) of the MEMTOR-V. The transmission chain (12) exerts a tangential force - from above the sprocket (10) - - in the clockwise direction as the lever arm (8) rises due to the swing. And the transmission chain (13) exerts a tangential force down the chain wheel (11) also in the clockwise direction as the lever arm (9) rises. It happens alternately and in all two previous cases the irreversible clutches of the sprockets are activated. The activation of the irreversible couplings causes the shaft (15) to rotate in a clockwise direction and this shaft (15) transmits its rotational movement to the flywheel (D). As the lever arm (8) goes down, the transmission chain (12) is retracted by the tension spring (17) and the sprocket (10) rotates counterclockwise without activating its irreversible coupling; and as the lever arm (9) goes down, the transmission chain (13) is retracted by the tension spring (20); the chain wheel rotates anti-clockwise without activating its built-in irreversible coupling. Thus, with the reciprocating of the mast and its counterweight, the flywheel (D) receives twice a push in the clockwise direction. And so a uniform rotational movement of the flywheel is transmitted to the axis of the electric generator by means of the drive belt (16). There are only two dead moments during the transmission and these are like the lever arms (8) and (9) at their heights during the swing.

Description of the orientation system with regard to wind direction at sea (Figure 1):

This orientation system consists of a platform (23) that can float on water with a compass that consists of a mast (28) that is also telescopic, with a fixed plate (22) at the top of the mast. This plate is connected vertically, fixed, above, to the mast such that its plane is perpendicular to the (SP) axis. The mast (28) of the wind rudder is vertically fixed at the end of the platform (23) on the side of the lever arm (9) of the counterweight (5). This orientation system also consists of an anchor (27) with chain which, if fixed in the bottom of the sea (or a lake), also plays the role of fixed pivot of the orientation of the machine with regard to the direction of the wind. By pushing the rudder, the machine gets a position such that the wind blows perpendicular to the (SP) axis in the direction of the anchor towards the mast (28) of the wind rudder; the fixed anchor (27), in the bottom, serves as the pivot point of the platform in its search for the best position for the operation of the machine.

Description of the orientation system with regard to the direction of the wind of a wheeled machine. (Figure 5):

This orientation system consists of a rectangular platform (34) on two axles (53) and (56) and on four wheels (52) and which are parallel with respect to each side of the right angle; it also consists of a rotating shaft (51) - with thread and nut (55) - that is in the middle, under the platform (34), in such a way that it can be fixed to the ground, using support (54) to play the role of center of rotation during orientation. This orientation system also consists of a compass with a vertical and telescopic mast (28) with a plate that sits vertically on top of the mast and is also perpendicular to the (SP) axis. The mast is at the end of the plateau, left . By pushing the wind rudder, the machine gets a position such that the wind blows in the direction of the central axis (51) towards the wind rudder (28).
