Definitions

  • My invention relates to new designs of windmills in several types to obtain maximum benefit from the energy offered by the wind in a given limited space at a minimum cost.
  • the windmill In the convertion of the wind energy particularly by means of the windmill, it is very essential that the windmill be in contact with as much wind as possible that passes thru a given space at the minimum cost of materials, labor, maintenance, operation cost, and minimum use of space (land or sea), in order to provide competative energy cost to the user.
  • This maximization of wind contact is done by the use of large wind sails made as large as possible, as in the sail boat, with the use of a specially designed mechanical device that handles the large sails in great quantities, at least cost.
  • the first prior art is the rotary blade windmill which has very limited power output capacity because it cannot be expanded large enough as much as it is wanted so as to increase the wind contact.
  • To increase the wind contact of the old rotary windmill is done only by attatching longer blades but only to a limited extent because the tip of the blades will be moving faster than the wind - that means loss of energy.
  • This means that the old rotary type of windmill cannot be constructed to a very large scale for purposes of having as much wind contact as it might be wanted.
  • the available wind being offered by nature is so much on land as well as on the ocean from sea level to 3 miles up all over the earth -- but the rotary windmill is just too small to tap the opportunity. From this view point, there must be another design of a windmill that can maximize wind contact any where in order to maximize benefits from the available wind, hence, the new invention herein presented.
  • the second prior art is that presented by H. A. STENNER under U.S. Patent No. 3,504,988 which makes use of a wind sail carried by a trolley which assembly is linked to other several trolleys with sail in a closed circuit traveling along an elongated closed loop double track railway.
  • the system is provided with electro-mechanical control system to keep the sail oriented to the direction of the wind.
  • This system is also provided with a closed loop drive chain which is tugged by each of the trolleys, and which drives the terminal gear that drives directly an electric generator.
  • the mast holding the sail stands alone without guy wires.
  • the sail which is supported vertically along the middle axis by the single mast is built rigid thick and solid designed not to bend any part against the wind force.
  • the Trolleys are supported vertically on its four (4) corners by wheels running inside a channel-shaped beam laid on its side that serves as rail track.
  • the principle envolved is best because it attemps to make the several sails to work in consortium but the following defects prevents the commcercial use of this invention:
  • the mast that holds the sail is not provided with guy wires and/or strut braces. This reduces the size of sail it can hold against the forces of the wind. Wind contact/cost ratio therefor is very low; 3.
  • the sail is built rigid and thick with double wall designed not to bend any part against the wind force. This makes the sail very heavy with too much materials used. Wind-contact/- cost ratio therefor is very low; 4.
  • the trolleys are supported on four (4) corners by wheels for vertical loads only. There are no wheels to take care for horizontal loads which are directly imparted. by the wind -- causing great amounts of friction upon the vertical inner walls of the channel-beam track by the wheels — hence, low effeciency in energy convertion due to energy losses;
  • the third prior art is that presented by Reinhold H. Nilberg, U. S. Patent No. 4,175,910 which makes use of several vanes as sail suspended vertically by two level cable conveyor system.
  • Each of the vanes are supported by two vertical, control bars connected at the top to the upper conveyor cable and connected at the bottom to the lower conveyor cable.
  • Each of the vanes contribute force to move forward the upper and the lower cable which in turn rotate the terminal gears at the same speed (upper and lower gear) to keep the vanes always vertical and prevent distortion of the system.
  • the principle envolved is best because it attempts to cover a wide path of the wind, increasing the wind contact, and attempts to unite the efforts of several sails to work in consortium, but the following defects prevents the commercial use of this invention in large scale, to wit: 1.
  • the vanes must be constructed thick and rigid enough to resist twisting as the wind exert force on them because the spring support is acting at one end only at a time. This tends to make the vanes very heavy causing an overload of the system, hence, this invention is limited to a very short span;
  • counter weight 19 is an error because it will desalign the wheels from the catenary slope of the conveyor cable. This will cause friction upon the lips of the gear wheel pulley and wear out the cable conveyor;
  • This windmill drives directly an electric generator without using a compressed air that would be coming from a large storage tank. This will cause a very unstable supply of electricity.
  • the fourth (4th) prior art is that presented by GODFREY BLACKMAN, British Patent No. 1,588,600, April 1981 which makes use of several wind sails on vertical mast carried by upper and lower bar chain 13,14 which in turn run on wheels following an elongated closed loop upper and lower railway on top of a two-span bridge 1 which in turn rests at its ends on another arc railway track 6,7 on the ground.
  • the theory in this invention is best only on the matter that it attempts to unite the efforts of several sails to work in consortium which is the same principle or objective that the aforementioned 2nd and 3rd prior art are trying to accomplish, but the following defects prevents the commercial use of this invention in large scale or in small scale, to wit: 1. There is too much materials to be used and too much expenses in the construction of the bridge that carry the whole windmill system ;
  • the Fifth (5th) is that presented by LAIRD B. GOGINS, U.S. Patent No. 4,302,684 dated Nov. 24, 1981 which attempts, as in aforesaid prior arts, to unite the efforts of several airfoils, in this case, in the form of vertically and rigidly standing airplane wing -- one wing mounted on and independently carried by separate trolleys that run around an elongated closed loop railway. Each trolley carry its own electric generator and produces electricity thru the turning of the individual wheels and in turn the electric energy is transmitted to a common bussalong the railway track.
  • Each trolley carry its own independent Diesel Engine to continue running the trolley around the railway track during the times when the wind is insufficient so that the wheels of the trolley will continue turning which in turn keep on driving the individual electric generators in order to maintain a continuous power output.
  • the theory in this invention is best only on the matter that it attempts to unite the efforts of several airfoils such as the standing wing to work in consortium which is the same principle or objective that the aforementioned 2nd, 3rd, and 4th prior art are trying to accomplish, but the following defects prevents the commcercial use of this invention in large scale or in small scale, to wit:
  • the standing airplane wing 300 ft high requires a heavy frame contruction to stand rigid against the wind it being supported on two points only, and to stand rigid like a crane boom against the downward compression effects of the guy wires;
  • the rail track requires a heavy concrete construction in order to produce an open trapezoid channel section rail large enough to accomodate the wheels into the internal dimentions of the channel.
  • the horizontal cantelever lips of the rail that serve as bearing to hold the wheels must be constructed strong enough to be able to contain the heavy vertical weight of the trolleys;
  • the ground which serves as footing for the heavy rail track needs to be horizontal, level and well compacted roadway which requirements makes this invention very selective of project site and is limited to a very few available choice lands; 4.
  • the design of the airfoil being a wing, is very very very narrow which in effect, with all the wings arranged along the rail track, will contact or deflect 1/7th only of the total wind available that is traversed by the rail track, hence, this particular prior art has the least wind-contact among all the prior arts;
  • this prior art is very expensive due to the construction of heavy structural framework for the wing, due to the construction of heavy concrete trapizoid channel rail, due to the construction of a level& well compacted roadway to serve as footing for the heavy rail track, due to the requirement of having 48 wheels for every trolley, due to the requirement of having one diesel engine for every trolley, due to the requirement of having one electric generator for every trolley, and because the wing has a very small wind-contact the resulting output/cost ratio is very small and disappointing.
  • the Sixth (6th) prior art is that presented by RUTLER under France Patent No. 2523220 dated Sept., 1983 which makes use of and unites the efforts of several sails as in the aforementioned prior arts.
  • the sails are double wall, rigid like that of the airplane wing, supported by a rotating vertical mast(without guy wires) which is in turn erected on top of a continuous circular horizontal frame that turn around on rollers on top of a circular horizontal rail track.
  • the pick-up wheels fixed on the ground driving the electric generator is actuated by a continuous circular friction plate attached to the main circular frame that act as vehicle for the sails.
  • the sail is designed to act stiff against the wind like an airplane wing -- so it requires a heavy structural frame it being a double wall with the assistance of guy ropes, hence, it is an expensive construction;
  • the mast which supports the heavy sail, stands alone without the assistance of a guy wire, must be a heavy structure to withstand the tremendous bending stress at the base, otherwise, the size of the sail must be a small one; 6.
  • the system being a circular horizontal structure occupies a very wide level land, hence, the maximum size of this type of windmill is limited only to the available diameter of the level land project site; 7.
  • the main circular frame (part 4) which revolve around on top of the circular rail track requires a very massive structural construction in order to be able to hold the heavy mast uprignt against the wind, and since this main frame is continuous around the circualr rail track it is a very expensive structure. Summing up all the aforementioned defects of this design, the resulting energy-output/cost ratio is very small.
  • the Seventh ( 7th ) prior art is that presented by Bruno May under Anlagen Patent No. 2836922 dated March 13, 1980 consisting of large quantities of composit sail mounted on a continuous floating circular raft on a lake and the other one presented by British Patent No. 25,234 dated Dec. 1394 consisting of sail boats floating and traveling thru a concrete circular channel - the boat being a continuous ring structure with the same diameter as the concrete water channel and acting as pulley that drives the power chain.
  • These two prior arts being a revolving circular structure, has the same defects and deficiencies as tne aforementioned Sixth (6th) prior art by Rutler under France Patent No. 2523220 in which I have listed 7 impediments in page 7 hereof preventing commercial use of these circualar designs.
  • the "UNITED SAIL WINDMILL” is designed to solve all the aforementioned problems or impediments encountered preventing the large scale commercial use of the aforementioned prior arts, and further intends to accomplish the functions of the crises creating "OIL” and/ or the dangerous expensive nuclear energy in the poor countries.
  • This newly invented windmill is designed to have as much wind contact as may be desired and intends to work even during the violent weather when the energy is abundant which is to be stored in the form of compressed air in large underground tunnels. The compressed air will, in turn, drive the electric generator to an extended time even after the windmills (in consortium) had stopped working as the wind stops. it is also designed to be easily constructed by the ordinary man out of low cost materials that are already available.
  • TYPE-4, TYPE-5, and TYPE-6 all solve the maximization of wind contact by making the wind sails as large as desired and attaching as many sails as desired in the maner as shown in the drawings thereby operating the windmills in a very large commercial scale is very easily attainable.
  • a common depository air tank in the form of underground tunnel or a series of tunnels thru a mountain ) in order to be able to drive a large electric power plant;
  • the herein presented inventions No. 2, No. 3, No. 6, No. 7, and No. 8 are the most important components that brought about the possibilities of expanding the different types of the "United Sail Windmill” into very large windmills as may be desired because they make the windmill work and stand rigid against the strong winds thereby allowing the construction of a very long span transverse to the general direction of the wind, hence, a very powerful windmill;
  • FIG. 1 is a schematic perspective view of tne invention No. 1 — "UNITED SAIL WINDMILL TYPE-1" showing the arrangement of at least Twenty (20) large wind sails, the power chain, the terminal gears, and the support structures. It is a long line of parading wind sails, transverse to the wind in one direction, that turn around a terminal gear at one end of the loop then make another long line of parading sails in the opposit direction (may be one or more miles long), then turn again at the other terminal gear at the opposit end to make a closed loop.
  • Each wind sail is suspended in mid-air by a horizontal power chain at the top and by another horizontal power chain at the bottom that move horizontally at the same speed by driving the upper and the lower terminal gear which are synchronized and locked to each other by a long vertical axil that carries the power take-off gear and which is held in place by a strong structural bearing. Since there are inteimidiary supports for the power chain to hold it in place, as shown in the drawings, the power chain will not sway side ward nor be overloaded, and this permits the construction of a very long and very large windmill of this kind even one or three miles or more miles accross a windy valley carrying one thousand or more sails in the system.

Also shown is a roller pulley with a long toothed Gear Lock (invention No. 6) that carry the sail on the Cable Rail. The long toothed Gear Lock prevents the sail from being derailed during violent weather. Also shown are new designs of cable rail switch on/off which allows the gear lock to pass thru, and the mid-air intermediate support for the cable rail that allows the gear lock to pass thru also. These are invention No. 7 and invention No. 8 respectively.
  • FIG. 6 is a schematic perspective view of invention No. 9 -- the "UNITED SAIL WINDMILL TYPE-4 which is a long line of several sails similar to the herein aforementioned windmill Type-1, but in this Type-4 all the sails are running on an elongated (a mile or more) closed loop Rail Road Track and there is only one Power Chain being tugged along the rail track by the wind sails on trolley. Also shown are the three synchronized Power Terminal Gears at each end loop of of the rail track which are directly anchored to the ground.
  • FIG. 7 is a schematic perspective view of the invention No. 10 "UNITED SAIL WINDMILL TYPE-5" which is similar to the herein windmill Type-4, but in this Type-5 each wind sail is carried by a Sail Boat and the whole windmill is constructed floating on water surface (lake, sea or ocean) forming a long parade of sail Boats (a mile or more) in one direction, turn around on the terminal gears at the end loop, then make another long parade of Sail Boats in the opposit direction and turn around at the opposit terminal to make a closed loop also shown is a barge anchored to the sea bed which carry the terminal gears and serves as power terminal station.

  • the power chain 101 turns the terminal gears 102 which drives the synchronizing chain 125 which joints the forces of the three terminal gears 102 in order to distribute the great force of the chain to more tansvers bars 116 of the chain 101 that are in contact with the terminal gears 102.
  • the center terminal gear drives the power take-off gear 114.
  • Rope 147 holds high the sails thru bearing 131 that allows the sail to turn around the mast 110.
  • FIG. 7 illustrates an embodiment of the invention No. 10 named "UNITED SAIL WINDMILL TYPE-5" which has the same principle and of similar construction as the aforementioned windmill Type-4 except for the following special features, to wit:
  • the whole windmill system is floating on water (sea or lake, or on the ocean);
  • Each of the wind sails 100 is carried by a separate boat 154 on which the mast 110 is erected and forms a very long line of parading sails out on the ocean;
  • the terminal gears 102 in triangular formation, are installed on top of a floating barg 153 which is held in place by anchor blocks 112 thru guy rope 108.
  • the sail 100 exerts force on the boat 154 to a direction opposit to where the wind is deflected.
  • the counter weight 151 moves to the opposit side of the boat thru a small rail by action of a rope being pulled by the sail 100.
  • the boat 154 moves forward, it tugs the Power Chain 101 by the tug rope 148.
  • the boats 154 turn around at the terminal by the action of the Power Chain 101 upon the front tug rope 148 which pulls the boat 154 to where the power chain 101 is going.
  • the fender plate 152 prevents the boats 154 from getting over into the other side of the power chain 101, at the same time prevents the boat 154 from being blown sideward by the wind resulting to an unnecessary stress to the power chain 101.
  • Strat braces 145 keeps the mast 110 stay erect rigidly.
  • Bridge 154 carry the whole weight of the mast 110 and keep the float 150 stay together in the form of an "H" frame.
  • Bearing 131 carry the whole weight of the sail 100 thru string 147 and allows the sail 100 to revolve around themast 110.
  • This barg 153 is anchored to the ocean floor by means of heavy block 112 thru rope 108.
  • Control rope 111 holds the sail to face against the wind, which has guaged springs that will relax the sail 100 when the force of t he wind becomes excessively strong, but tries to adjust the sail 100 to be fully facing the wind when the speed is very low.
  • the boat loaters 150 and the barg 153 will be deflated to submerge the whole system under water to scape distinction by strong winds and haeavy water waves. When the hurricane is gone, the whole system will be refloated again by means of compressed air.
  • This type of windmill is expandable as much as the open ocean by installing intermidiary horizontal supports at several points along the span of the power chain 101 in the form of a deep groove roller pulley with lock gear similar to parts 107 & 118 shown in Fig. 3 which will be mounted on floating floating rafts anchored to the ocean floor.
  • Fig. 8 illustrates an embodiment of the invention No.11 named "UNITED SAIL WINDMILL TYPE-6" which has similar principle and construction as the aforementioned windmill Type-1 except for the following special and additional features, to wit:
  • the axil 105 of the terminal gears 102 are horizontal;
  • the sails 100 & 200 are blown up and spread open by the wind upon turning up and ride on top of the pair of Power Chain 101.
  • the sail 100 carries with it additional sails 200 that flip out open on each side of sail 100 and another 3rd sail 200 that flip out open down ward at the bottom of sail 100 between the power chain 101 to maximize blockade against the wind for more energy benefits;
  • the whole system is an inclined line where the front terminal gear 102 is at a low elevation while the rear terminal gear
  • Part III is the guy rope that makes the sail stand rigid against the wind, which has a control spring that is able to relax the sails when the wind is excessive.
  • the ground foundation 113 hold the post 103 in place.
  • Several windmills of this type-6 may be constructed adjacent and side-by-side to each other using the structural posts 103 as common post for every adjacent windmill, while the axil 105 can be made continuously long axil common to all succeeding side-by-side windmills. In the construction of several adjacent windmills of this type, the axil 105 may be preferably cut and discontinuous to provide clear space for the bottom sail 200 so that same can be constructed to be a wider and longer sail and to save axil materials.
  • the only axil needed will be the axil holding the right terminal gear 102 of the first windmill at the same holding the left terminal gear 102 of the next adjacent windmill on the right, and so on. In this preferred mood, maximunm wind contact at least cost of energy convertion can be attained.

Abstract

Le but est de produire un moulin à vent en grande échelle mais de faible coût en maximisant le contact avec le vent avec les matériaux les moins coûteux et un coût d'entretien moindre. Ce but est atteint en réalisant les voiles (100) aussi grandes que possible à l'aide de matériaux légers tels que des toiles structurées ou des feuilles d'aluminium, en disposant les grandes voiles (100) de manière à former une longue ligne de voiles en succession suivant une direction transversale à la direction du vent et une autre longue ligne du même genre parallèle à la première ligne mais se déplaçant dans la direction opposée et avec laquelle la première ligne forme une boucle fermée, en utilisant une chaîne à câble solide légère (101) qui est remorquée par les grandes voiles et qui également fait tourner les pignons terminaux (102) situés aux deux extrémités de la boucle, en utilisant des véhicules légers pour porter les grandes voiles.
