Definitions

  • the disclosure relates to wind turbines distributed within closed buildings above/ underground. They are operated by (naturally/ mechanically) pumping wind from one side of a building and withdrawing it from the other side. Thus, a strong air stream will be generated whereby turbines can be efficiently run, and as a result electricity will be generated.
  • the present invention aims at getting rid of all these drawbacks. It allows fixing wind turbines within closed above/underground buildings with no need to such high towers to reach the required air velocity. Furthermore, the present invention provides such avelocity inside a building. It is also characterized by operating turbines within closed buildings using the energy of natural mild wind as this can double the strength and the velocity of natural mild wind within a building. The wind is contained then pumped into the turbines of the closed building so that the wind enters from one side of the building and exits from the other side forming a strong stream that drives turbines. Providing the building exit openings with fans that withdraw and expel the wind outside can reduplicate the wind strength and velocity within the building.
  • the present invention enables the construction of successive and unlimited closed buildings that are interconnected.
  • Each building includes a field having a proper number of turbines.
  • the wind is (naturally or mechanically) pumped only from the first building and (mechanically) withdrawn from the last building. This generates a strong air stream whose strength and velocity can be controlled to run the turbines efficiently.
  • the invention relates to indoor turbines. Buildings are either above or under the ground.
  • a building contains a field having a proper number of wind turbines (at least one big turbine).
  • the turbines in this field are operated in two ways: Firstly: A number of wind mounts are deployed against wind in potential work places (wind turbine fields). Natural wind enters the mounts and is directed to (naturally) enter the turbine building from one side and (mechanically) exit from the other side by means of big suction fans. The wind movement between the two sides results in a continuous steady air stream that runs the turbines continuously. The wind velocity within the building is multiplied by increasing the number of wind receiving mounts as well as the number of suction fans that, when operated, strongly draw the wind from the building and expel it in the fresh air.
  • Building turbines can be (mechanically) wind operated with no need to equip a building with wind mounts.
  • a closed building may be provided from one side with entry slots having high-power propeller fans, and, from the other side, with exit slots having strong suction fans.
  • propeller fans On operating the propeller fans, they (mechanically) pump wind into the building and at same time, the wind is (mechanically) drawn from the building. Thus an air stream will be created and run the turbines.
  • Wind mount (1) with suitable size and number. They are used for containing natural outdoor wind.
  • the velocity of the wind inside the building can be (exponentially) reduplicated by increasing the number of suction and discharge fans.
  • the wind can run the turbines much more powerfully than the turbines outdoors. Studies indicate that duplicating wind velocity increases turbine power 8 times.
  • the building of turbine field (1) having proper dimensions that is used as a closed building in which there is a plurality of wind turbines.
  • Tubing/ openings (2) used to allow wind from the fresh air enter the turbine building.
  • High- capacity propeller fans (3) fixed in the entry openings and used for drawing wind from the fresh air and pump it (mechanically) into the building.
  • Exit tubing/ openings (5) used for discharging wind from the building to the fresh air.
  • the above-mentioned embodiments can establish successive and unlimited closed buildings (as shown in Fig. 3). Such buildings are interconnected by tubing that connects each building with the next one. Each building includes a field having a suitable number of turbines. (Only) the first building is attached with wind receiving mounts. Exit openings (only) in the last building are provided with strong suction fans. On operating the propeller fans, they (mechanically) pump wind into the building and at same time, they mechanically draw wind from all buildings (continuously). Thus, the wind enters the first building naturally and goes (steadily) to the last one wherefrom it exits (mechanically). An air stream will be created and run all turbines in the buildings simultaneously with the same operation capacity.
  • the two embodiments of the invention overcome the following problems facing the existing wind turbines:
  • the existing turbines need high towers to reach a proper air velocity.
  • the invention can secure fast wind within a closed building without the need to build high towers.
  • the required wind velocity for turbines capacity can be obtained so that user can control the velocity of the wind entering turbine building by controlling the number of from one end and the number of suction fans from the other end.
  • FIG. 1 General perspective of the first embodiment wherein wind mounts are outdoors and mounted on the ground against the wind.
  • the mounts hold natural wind and send it to the closed turbine building.
  • the wind enters from one side of the building and exits from the other side which is provided with suction fans that pull the wind out of the building and expel it to the outside, creating a strong air stream that actuates the turbines.
  • Figure 2 - A general perspective of the second embodiment consisting of a closed building with entry openings equipped with fans that push winds into the building from one side and discharge it from the other side with the help of suction fans so that a fast and continuous air flow is formed to actuate the turbines.
  • FIG 3 Several closed buildings are connected to each other by tubing that allows winds to exit from one building to the next one. It is noted that at the top the wind is pumped (mechanically) into the closed building and exits the building (mechanically) . At the bottom of the figure, wind is (naturally )pumped into the building by the mounts and get out of the building (mechanically)
  • the invention aims to benefit from the energy of mild natural winds, especially where wind turbine fields can be deployed and where it is possible to drive(small or medium) turbines in the open air. These mild winds are drawn and pumped into a closed building. The velocity and strength of these winds actuate turbines with higher capacities compared to the turbines managed by mild wind outside the building. This may redouble the production .
  • the means of implementing the invention are as follows:
  • Means of implementing the first embodiment as shown in Figure 1 Installing (1) iron mounts raised on strong poles to a suitable outdoors in places (candidate for deploying wind turbine fields) where the wind velocity in such fields are often ranging between (4-8m / second). Such mounts have large nozzles at the front which gradually become smaller ending with a large iron pipe. The size, dimensions and capacity of the mounts are determined by technical calculations and mathematical equations so that they hold the largest possible amount of winds per second.
  • the mounts' nozzles can be movable and rotatable around an axis and attached to sensors that make the nozzles always face the wind.
  • the building of the turbine field (3) that is made of iron, concrete, or any other building material. This building is closed and the wind coming from the mounts enters it (naturally) and exits from its other side mechanically. A continuous air streamis formed inside it that drives the turbines fins. It is to be noted that the more mounts the greater the velocity and strength of the wind inside the turbine building. The many mounts will act as natural fans that pump strongly natural air into the turbines building in direct proportion to their number.
  • Wind turbines (4) are installed inside the closed turbine field building. Their number (at least one turbine) is suitable for wind energy inside the building. They are distributed in the building in specific positions determined by technical calculations and with capacities suitable for wind energy inside the building. The technical distribution should take into account the influence of air pathways inside the building so that the wind is evenly distributed to turbines.
  • Suction fans (6) are installed inside the exit openings in the pipes (5). They should be technically appropriate using accurate calculations so that the force of drawing the wind pulling from inside the building and discharging it outside the building has a direct relationship to the rate of the wind velocity inside the building. In other words, the wind velocity inside the building is equal to the rate of wind charging outside it, so that the wind velocity inside the building can be controlled by changing the number of suction fans. Technical matters can be precisely considered for implementing the invention.
  • the mounts (1) facing the wind receives it from the fresh air. Then, the wind enters the mounts (naturally), and from there it travels through the tubing (2) to the turbine building (3) uninterruptedly.
  • the incoming wind actuates the turbines (4) and exits from the end of the building (mechanically) by means of suction fans (5) that expel the wind out through the tubing (6) continuously.
  • Means of implementing the second embodiments shown in Figure (2) The building of the turbine field (1) that is made of iron, concrete, or any other building material. This building is closed and the wind enters it by means of tubing or openings in one side, wherein the wind is mechanically introduced by propeller fans and mechanically discharged from the other side. A continuous air stream is formed that drives the turbines fins. It is to be noted that the greater the number of mounts the greater the velocity and strength of the wind inside the turbine building.
  • the pipe opening outside the building is large and has a diameter that is accurately calculated. It is installed in one side of the building wherein it is used to introduce the wind into the building at the required velocity and amount.
  • - Propeller fans (3) with high capacities (such as large tunnel fans). They are installed inside wind entry openings/ tubes and are used to draw wind from the fresh air and pump it mechanically into the building with high capacities for rapid pumping that is measured in meters per second.
  • Wind turbines (4) are installed inside the closed turbine field building. Their number is suitable for the wind energy inside the building. They are distributed in the building in specific positions determined by technical calculations and with capacities suitable for the wind energy inside the building.

Abstract

L'invention concerne des éoliennes fonctionnant à l'intérieur de bâtiments (fermés). Ces éoliennes isolées sont actionnées (naturellement) par le pompage du vent d'un côté d'un bâtiment et l'expulsion mécanique de celui-ci de l'autre côté au moyen de ventilateurs (d'aspiration). En variante, les éoliennes peuvent être actionnées (mécaniquement) par le pompage du vent d'un côté d'un bâtiment et (mécaniquement) l'expulsion de celui-ci de l'autre côté au moyen de pompes (d'aspiration) qui retirent le vent du bâtiment et l'expulsent en continu, ce qui génère un flux d'air fort dans le bâtiment ayant la vitesse requise pour actionner efficacement les éoliennes. De nombreux bâtiments adjacents peuvent être construits en étant reliés les uns aux autres par des tubes qui peuvent permettre un transfert facile du vent d'un bâtiment à un autre. C'est uniquement le premier bâtiment qui (naturellement ou mécaniquement) reçoit du vent (naturel ou mécanique). Les ventilateurs du dernier bâtiment aspirent le vent et l'expulsent en dehors, ce qui permet de générer un flux d'air fort dans tous les bâtiments et d'actionner toutes les éoliennes en même temps et avec la même capacité de fonctionnement. L'invention vise à actionner des éoliennes à l'intérieur de bâtiments (fermés) à l'aide de vents (naturels/mécaniques) dont la vitesse peut être régulée et la production d'électricité peut être augmentée. L'invention vise également à résoudre les problèmes actuels des éoliennes tels que : le bruit audiovisuel, l'abattage des oiseaux, la nécessité d'un vent rapide et stable, et le coût élevé de la tour de construction pour atteindre la vitesse du vent requise. La présente invention concerne des éoliennes avec le vent requis à l'intérieur de bâtiments fermés avec la vitesse requise.
