Description

MULTI-PURPOSE WIND DEFLECTOR-GENERATOR-ACCELERATOR

Field of the invention

This invention relates to wind machines which are capable of accelerating the wind in a site so as to produce much more power and simultaneously extract soft water from the atmosphere.

Background art of the invention :

In wind energy field, wind speed is the most important factor which affects production of power; the output power of a wind machine is proportional to the cube of the wind speed. Hence, double the wind speed gives eight times the output power, and three times the wind speed gives 27 times the output power, and so on.

The second important factor is the resisting air drag on an upwind vane of a vertical-shaft wind rotor. Said resisting drag is proportional to the square of the sum of wind speed and rotor speed

2 (wind speed + upwind vane's speed) .

Said drag is a retarding force which retards the movement on the rotor, slowing it down and subsequently reduces its output. Hence, if the upwind vane^' was protected from the wind stream, an important reduction in the said resisting drag would result in; subsequently the efficiency of the rotor would increase. The above-mentioned reduction is. approximately 75% of the total said resisting drag.

But the most difficult pr'øbl.-ams- were ;____

1. How can the wind in a specific site be accelerated ?

2. How can an upwind vane of a vertical-shaft wind rotor be protected from the stream of wind whose direction is changing occasionally ?

An object of the present invention is to provide practical solutions to the mentioned difficulties; furthermore, to provide a solution to the problem of shortage of soft water, particularly in coastal areas.

Summary of the invention

The present invention is a group of inventions so linked as to form a general function; that is to extract much more power from wind and, simultaneously, extract soft water from the atmosphere.

The invention will be better understood thanks to detailed description of particular embodiments given by way of non-limitative examples only, with reference to the accompanying drawings,, in which two types of wind machines are illustrated. The first is a vertical-shaft type while the second is a lift-type one.

DETAILED DESCRIPTION OF THE INVENTION

For better understanding of the invention, each type will be described in sequence.

THE VERTICAL TYPE

Referring to figures 1, 5 the vertical type comprises four general components each comprising a number of parts.

1. Component A whose essential parts are referred to by a number plus the letters A.V.;

2. Component B.V. which is the rotor and its attached parts.

3. Component C.V. which includes the platform and a number of parts mounted on it.

4. Component D.V. which comprises a station for squeezing the received precooled air to extract water from it and for thrusting both cold dry air and hot air each through its duct up to the rear slots in the tail vane.

Figure 1 shows the vertical type as it is assumed to be when it is. in the operative position. The movable curved fences 1 A.V. , 2 A.V. are oriented by the tail 3 A which is pushed by the wind when it blows. These two fences perform the following tasks :

1. Fence 1 A.V. performs the following tasks : The first one : it protects the upwind vane of the rotor B.V. from the wind so as to get rid of the resisting air drag on the said vane; said drag, caused by wind is, as mentioned above, a retarding force whose magnitude is proportional to the square of the wind speed. So, fence 1 A.V. saves this force which is approximately 75 % of the total resisting drag which the upwind vane of a vertical-shaft rotor usually suffers.

The second task : it deflects half of the wind it receives so as to send it to the downwind vane to give it more thrust. Said tasks increase the efficiency of the rotor.

The third task : it takes part in accelerating the wind (the whole operation of accelerating the wind will be described later) .

2. Fence 2 A.V. performs the following tasks :

The first one : it balances fence 1 A.V. so as to keep fence 1 A.V. facing the wind. In order to achieve this, its frontal area is much less than the frontal area of fence 1

A.V. but its moment arm is longer; this is governed by the equation : frontal area of 1 A.V. X- moment arm of 1 A.V. = frontal area of 2 A.V. X moment arm of 2 A.V.

The second function : it deflects half of the wind it receives and sends it to the downwind vane of the rotor B.V. to give it some additional thrust.

The third function : it takes part in supporting the coil 4 A.V. of the generator.

The fourth function : it takes part in accelerating the wind (as will be described later) .

Rotor B.V. is a Savonius rotor but with some improvements. Said improvements are as follows :

1. Condenser and evaporator coils 4 B.V. figure 5, which are members of a refrigerating circuit, are mounted to its vanes, said coils are pipes made of an aluminium alloy of the group G-AlSilO Mg. or the like. Two coils are mounted to each vane; one to the upper part where it acts as a condenser and in the same time enhances the vane itself; the other is mounted to the lower part of the vane where it acts as an evaporator and in the same time enhances the vane. The two said coils are welded to the concave surface of the vane which is made of sheet aluminium.

Said coils take part in accelerating the wind. In other words, the upper one acts as a surface cooler (this will be described later within the description of accelerating the wind) .

2. Permanent magnets 2 B.V. are fixed in the middle of the edge of each vane; said magnets are assumed to be as light and strong as possible; in other words : of high quality, for instance (rare earth-colbalt) or (platinum-cobalt) or the like.

The gap between north and south poles is very narrow; just a few centimeters to allow a passage for the coil 4 A.V.. This narrowness permits high efficiency of the main electric generator whose coil 4 A.V. is fixed to component A (it is worth mentioning that, in physics, the product of a generator is inversely proportional to the square of distance between N. and S. poles) .

Said magnets 2 B.V. comprise the moving (rotating) member, of the said generator, but in addition to that, they serve as flywheel to the rotor B.V.

3. Other permanent magnets 3 B.V. are fixed to the lower corners of the vanes, one magnet to each vane. Said magnet-s are all installed in the same direction (i.e. with the same pole, either north or south in the same direction). North pole upwards and south pole downwards or the other way round for both of them. Said magnets comprise the moving (rotating) member of the rotor accelerator-generator-brake; this multi-function generator, whose stator 6 C is mounted on component C.V., will be described in details, later.

4. A refrigerant generator 5 B.V. is attached to the lower center of the rotor B.V. around the axis of rotation; said generator is a ring tube made of non-metallic material, preferably, thermal plastic or any composition which can withstand both high pressure and high temperature and in the same time is not heavy.

The purpose of avoiding metallic materials, here, is that they reflect microwaves while non-metallic materials permit microwaves to pass through.

Said generator 5 B.V. is heated by microwaves produced by a magnetron situated below it, mounted on component C; said magnetron is stationary while the generator 5 B.V. rotates with the rotor B.V.; thus, heat is provided to the generator 5 B.V. by microwaves without any retarding force or any load such as a compressor or any conventional source of fire.

Said generator 5 B.V. is connected to the refrigerating circuit by a vertical pipe attached to the vane near the vertical shaft 6 B.V. to provide the condenser with hot gas (refrigerant) from the top of the vane, and is connected to the evaporator by a pipe to receive the refrigerant in the liquid case to reheat it and so on.

5. Its diameter can be as large as desired because a number of tyres can be installed below it mounted on component C, in any position between generator 5 B.V. and stator 6 C; such tyres are the same as 4 C. supported by 2 C, 3 C; said tyres will support the rotor B.V. in the same manner as component A is supported by tyres 4 C; so, no additional load is added to the rotor itself except for a flat ring which is to be welded to the lower ends of the vanes to keep in touch with the said tyres, and a slight loss will occur as friction force of the rolling tyres underneath.

Said way enables enlarging the diameter of the rotor to a wide range, even more than two hundred meters, which enables establishing giant wind power stations.

Tail vane 3 A. comprises three air ducts 8 A, 13 A, 14 A. and three fans 10 A, 11 A, 12 A; fan 11 A sucks the cold air from behind the rotor and fences 1 A.V. , 2 A.V. to drive it down to the cooling tower (not shown) in the station of extracting water (not shown) below the platform.

Fan 10 A. sucks very cold air from the water extracting station after water has been extracted from it, and thrust it behind the whole system in the same direction of the wind.

Fan 12 A. drives out the hot air which it receives from the water extracting station through duct 14 A. in the direction of the arrow shown in the drawing; and, also, in the same direction of the wind.

Said fan 12 A. is propelled by an electric motor 9 A. which is mounted outside vane 3 A. for the purpose of cooling.

Three tyres 4 C. are mounted on top of component C; each tyre on one of the three supporting towers; said tyre 4 C. revolves around shaft 3 C. mounted to the supporting rod 2 C. said tyres support component A. which is moveable; said tyres are in contact with a sheet ring (not shown) attached to the bottom of component A. , which rolls on the said tyres which are acting as bearings to component A. in addition to one bearing in the top of the vertical shaft 6 B.V.; so, when the wind changes direction, component A turns easily over the said tyres which need less maintenance. A ring tube A.V. made of non-metallic material is mounted to the bottom of component A to act as a refrigerating generator. Said generator is the same as generator 5 B.V. except for shape and size. Said generator A.V. is connected to the refrigerating circuit mounted to the fences 1 A.V. , 2 A.V.; said connection is made by some of the pipes 6 A.V. which are, also, for supporting and enhancing component A.

As in component B.V. , condensers are mounted to the upper halves of fences 1 A.V. , 2 A.V. while evaporators are mounted to the lower halves.

Heat is provided to generator A.V. by means of three magnetrons 5 C. each of which is mounted near each tyre 4 C.

Rotating covers 1 D., 2 D., 3 D. are the outside parts of the three air ducts in the dehumidification station under the wind machine (said station has not been shown because it is known and is not necessary for the understanding of the invention) . The mentioned covers are connected to the tail vane 3 A. as shown in the drawings so as to conduct hot and cold air as shown by the arrows.. Hot air duct is insulated by a suitable insulating material.

DETAILED DESCRIPTION OF THE ROTOR

ACCELERATOR-GENERATOR-BRAKE

As mentioned above, said multi-function generator comprises two parts :

1. The rotating member 3 B.V. which is a curved single pole of permanent magnet mounted to each vane of the rotor B.V.

2. The stator 6 C. which is, also, a curved single pole of permanent magnet with a solenoid mounted on its curved face to stand in the air gap between it and the rotating pole 3 B.V. A core is used inside the said coil, but both the core and the solenoid are also curved. This curvature enables the magnetic flux, induced by the passage of current in the solenoid, to be concentrated and correctly directed up to the opposite single pole 3 B.V., just a fraction of a second after it has passed over stator 6 C. , in order to give the vane an additional thrust. In other words : repulsion occurs between the solenoid and the rotating pole 3 B.V. just on departure of the rotating pole 3 B.V. from the position which is exactly over the solenoid; so, stators 6 C. are positioned in points which allow such timing, and the solenoids are linked by a conductor (wire) to form a circuit through which current induced in one solenoid passes through the others, but when one vane of the rotor B.V. is over the first third of the length of one solenoid, the second vane must be over the second third of the length of the second solenoid while the third vane must be just leaving the third solenoid.

Attraction, also, takes place between the solenoid and the vane; when the vane approaches the solenoid, it is attracted by means of the first end of the solenoid which acts as an opposite pole. So, the vane is propelled by both attraction and repulsion in addition to the wind.

Current induced by the said generator is added to the current induced by the main generator.

When a reverse current is applied to the solenoids, the said multi-function generator acts as a brake because reversing the direction of current through a solenoid reverses the electro-magnetic poles. Hence, the N pole takes place of the S pole; subsequently, the direction of both attraction and repulsion forces reverses, exerting retarding forces on the rotor B.V. to slow it down.

EXPLANATION OF THE OPERATION OF ACCELERATING THE WIND The idea of accelerating the wind is based on the fact that heating the air causes it to ascend; in other words, to travel upwards; and cooling it causes it to descend; in other words, to travel downwards.

In a given site, when hot air ascends and cold air descends, a low pressure area takes place in between; so, the nearby masses of air tend to move and fill the said low presure area; said movement accelerates the said masses of air.

A combination of natural convection cooling, natural convection heating and forced draught heating is used, according to the present invention, to provide a hot layer of air, moving in the same direction of the wind, behind the wind machine and to provide a cold layer of air, underneath the hot one, moving in the same direction so as to induce a low presure area behind the wind system; said low presure area is characterised in that it keeps taking place as far as the wind system is operating.

In the vertical typw shown in the accompanying drawings, the steps of accelerating the wind are as follows :

1. Rerfrigerant is heated in its generators 5 B.V., A.V. , by means of microwaves produced by magnetrons 5 C; so, it ascends through the hot gas lines to the condensers in the upper sections of the rotor B.V. and the fences 1 A.V. , 2 A.V. where it heats the said sections and subsequently raises the temperature of the stream of air which flows in contact with the said sections.

The lower halves of the hot gas lines are insulated by a suitable insulating material.

Being heated, the said stream of air will get lighter and will travel faster in ascension, in the same direction of the wind behind the wind system. 2. The lower sections of the rotor B.V., fence 1 A.V. and fence 2 A.V. (as they are evaporators) will cool the contacting stream of air which a portion of it is sucked by the sucking fan 11 A through air duct 8 A while the remaining portion travels away behind the system in the same direction of the wind, in a descending way.

3. Said cold air, sucked by fan 11 A, is brought to the station of dehumidification to be cooled until water is extracted from it; then it is driven away through the lower air duct 3 D to be sent, at last, through the slot 13 A, again descending behind the system, in the same direction of the wind.

4. Forced draught heating occurs, in the dehumidification station, to masses of air which are draught through air duct 2 D after having passed in contact with the surfaces of the condensers in the dehumidification station and are sent through air slot 14 A to apply additional heat to the hot layer of air behind the system and in the same time cool the said condensers.

Said masses of air are brought to the condensers from an opening facing the wind (in the dehumidification station) .

Thus, a low presure area is provided behind the system all the time during which the system is operating; this helps accelerate the wind giving an almost incredible increase in the output power of the main electric generator (2 B.V. , 4 A.V.), the multi-function generator (rotor accelerator-generator-brake) (3 B.V. , 6 C) and at the power-shaft 6 B.V.

Simultaneously, the condensate (water) is stored in a tank beneath the dehumidification station at a relatively high position above the ground in order to provide potential energy, when required, and to be used for drinking purposes or to be mixed with brackish water for irrigation. In the lift-type machine, shown in the drawings, the same principles, as in the vertical-type, are applied with only one exception. Said exception is that the rotor B.L. is not used as a wind accelerator. Only component A is used, in this type, as a wind accelerator.

The ring-shaped fence A.L. and tail vane 3 A comprise condensers in the upper sections of them and evaporators in the lower halves of them, while some of the supporting pipes 6 A.L. are also used as hot gas lines and some others are used as suction lines.

DETAILED DESCRIPTION OF THE LIFT-TYPE

Referring to figures 7, 8, 9, there is shown, the lift-type machine of the present invention

Ring-shaped fence A.L. performs the following tasks :

1. It deflects a portion of the wind it receives sending it towards the rotor B.L. to give it more propelling force.

2. It takes part in accelerating the wind as explained previously.

3. It supports the coil 4 A.L. of the electric generator.

Coil 4 A.L. is a conductor wound around a flat ring-shaped core.

Horseshoe permanent magnets 2 B.L. are mounted to the tips of the blades of rotor B.L.; said magnets are of high quality (rare earth-cobalt or platinum-cobalt or the like) .

The coil 4 A.L. is not thick, so, the air gap between the two poles of a horseshoe magnet is very narrow; this narrowness enables high productivity of the generator. Furthermore, the tip speed of the blades is very high in contrast with the speed of the rotating member of a conventional generator. For instance : a conventional generator of rated speed 200 r.p.m. at rated wind speed 15 km/h will achieve a tangential speed of approximately 4.2 m-/s if its diameter is 0.4 m while a two blade lift-type rotor of twisted airfoils having a tip speed ratio of 10 will achieve a tangential speed of 41.67 m/s; in other words, ten times as the conventional generator's tangential speed; this aspect is very important as the output power of a generator is directly proportional to the speed of either the magnetic poles passing by a coil or the coil passing through a magnetic flux. Thus, the present invention provides high speed of magnetic poles passing around a long coil situated in a very narrow air gap between the two opposite poles of magnet. All of the three aspects (narrowness of the gap, high speed of magnets and length of the coil) contribute in increasing the output power of the said wind generator.

Alternatively, sheet ring-shaped magnets can be used instead of horseshoe magnets, and in such a case, they will, also, serve as a kind of enhancing the blades, especially if the diameter of the rotor is very large.

No load is applied to the rotor, so, it spins faster. The only load it has is the magnets; thus, eliminating the need for transmissions and the maintenance of such transmissions, and save the loss associated with such transmissions and power-shafts.

A brake (not shown because it is not necessary for understanding the invention) is mounted behind the propeller boss to control the rotor and to govern its furling speed. Said brake can be a hydraulic brake which is run by an electric motor (not shown) with an electronic device (not shown) to operate it. Of course, the magnets are a kind of load especially in this case (with a considerably long moment arm) , but their advantages are :

1. They also serve as a flywheel.

2. They eliminate the need for transmissions.

3. They allow the air gap (the distance) between every two opposite poles to be as narrow as desired.

4. They serve as a fan to cool the coil as they pass.

5. They, themselves, are cooled freely by the wind.

6. They are in the only position which can enable them to ^• get the maximum speed.

7. They, also, form an additional frontal area of the rotor; that means that they, themselves, extract some wind energy which contributes in propelling them.

Pipes 6 A.L. are for supporting component A and are used, as mentioned above, as hot gas lines and suction lines.

Tail-vane 3 A is the same as that of the vertical type with all its parts the same; so, it will not be described again. The only differences are :

1. Motor 9 A is mounted in an upper position as shown in figure 9.

2. Air ducts 1 D, 2 D, 3 D are smaller than those of the vertical-type (as shown in figures 7,8,9).

3. Only one refrigerant generator 5 A.L. is used in this type with only one or two magnetrons 5 C. Vertical shaft 1 L. with bearings 2 L. is used as an axis for the whole machine to pivot around it in order to be directed to the wind and in the same time it supports an other axis around which the rotor B.L. rotates.

GENERAL ASPECTS CONCERNING THE TWO TYPES

Energy storage can preferably be made by means of water storage. High tanks can be filled by water produced by the dehumidification station directly without any need for pumping. In other words, the dehumidification station is installed in a high position supported by the towers of the wind machine itself, and the tanks of water are situated just below the said station so that the water extracted by the said station can flow into them by gravity then is used, when required, as potential energy to drive a conventional generator to provide power for starting the wind system and to contribute in providing power for the dehumidification station in addition to providing adequate quantity of soft water for purposes of drinking and irrigation.

Fortunately, coastal areas are rich with both winds and humidity; so, little power is needed for starting the system while large quantities of water can be extracted in a relatively low cost, in the said way.

Needless to say that most of coastal areas, all over the world, are suffering from the shortage of soft water; so, the present invention will be of great use for the said areas.

A clutch (not shown) is used to connect the power shaft of the vertical-type wind machine to the shaft of a water pump (not shown) to pump brackish water from a well in the site to a water tank which is built in a position parallel to the position of the soft water tank in order to be mixed with soft water and, afterwards, be used for irrigation as well as driving a generator to provide power. Such connection is done only when the rotor is running in high speed; in other words, when wind is blowing fast, and disconnection automatically occurs when the available wind speed is enough for only providing the minimum revolutions per minute needed for the main generator to produce electricity.

Some of the electric power provided by the system is used to operate the system itself; in other words, to provide power for the magnetrons and the fans and to contribute in providing power to the dehumidification station; while the remaining power (in times during which wind is blowing fast) is used for any desired purpose.

Transformers (not shown) are necessary to supply the magnetrons with suitable current, and inverters are also needed for the same purpose.

Frequency of the microwaves may be for instance of the order of 2450 million time per second (2,450 M Hertz).
