DETAILED DESCRIPTION
(6)
(7) The turbine rotor 104, as shown in
(8) The turbine rotor 104 may have alternative designs to the one shown in
(9) The bottom 116 of the turbine rotor 104 may include one or more of the magnets 110. The one or more magnets 110 located in the bottom 116 of the turbine rotor 104 provide an opposing force against one or more magnets 110 located on the turbine support 106. The opposing force created by the one or more magnets 110 reduces the weight load of the turbine rotor 104 on the turbine support 106, as will be discussed in more detail below.
(10) The turbine support 106 may be any suitable shape capable of supporting the weight of the turbine rotor 104 and stabilizing the turbine rotor 104 as it rotates about the axis 102. The turbine support 106, as shown in
(11) The surface 124, as shown in
(12) The platform 122 typically provides the support for the weight of the turbine rotor 104. The platform 122 may include one or more magnets 110B which provide an opposing force against the one or more magnets 110A located on the bottom 116 of the turbine rotor 104, as will be described in more detail below. The base 120 and/or the platform 122 may extend the same radial distance from the axis 102 as the turbine rotor 104. Alternatively, the base 120 may extend a shorter radial distance from the axis 102 than the turbine rotor 104, or, in another alternative embodiment, may extend a longer radial distance from the axis 102 than the turbine rotor 104. It should be appreciated that the platform 122 may be any suitable shape capable of providing a vertical support surface for the turbine rotor 104.
(13) The support shaft 118 of the turbine support 106 may provide for stabilization of the turbine rotor 104. The support shaft 118, as shown in
(14) The wind turbine 100 may include a connector 126, shown schematically in
(15) The one or more sets of magnets 110C, 110D reduce friction between the turbine support 106 and the turbine rotor 104 by creating a space between the turbine support 106 and the turbine rotor 104 due to the opposing forces of the magnets. The magnets replace the role of roller bearings in prior wind turbines. The one or more magnets 110A, 110B positioned on the bottom 116 of the turbine rotor 104 and the platform 122 of the turbine support may include one or more levitation magnets and one or more stabilization magnets. The levitation magnets supply an opposing force between the bottom 116 of the turbine rotor 104 and the platform 122. The opposing force created by the levitation magnets may create a force on the turbine rotor 104 substantially opposite to a gravitational force on the turbine rotor 104. The levitation magnets can provide a large enough opposing force to lift the turbine rotor 104 off of the platform 122 thereby eliminating friction between the platform 122 and the turbine rotor 104. Specifically, a space may be created between the platform 122 and the bottom 116 of the turbine rotor 104 as a result of the opposing force. Alternatively, the opposing force created by the levitation magnets may only negate a portion of the gravitational force, so that the friction force between the platform 122 and the turbine rotor 104 is reduced.
(16) The stabilization magnets 110D, 110C, as shown in
(17) Friction may be eliminated between the turbine rotor 104 and the turbine support 106 using both the levitation magnets and stabilization magnets. The one or more sets of magnets 110 may be any magnets suitable for creating an opposing force including but not limited to a permanent magnet, an electromagnet, permanent rare earth magnet, ferromagnetic materials, permanent magnet materials, magnet wires and the like. A permanent rare earth magnet may include samarium cobalt (SmCo) and/or neodymium (NdFEB). Further, the one or more magnets 110 may be arranged in any suitable manner so long as they reduce the friction between the turbine rotor 104 and the turbine support 106.
(18) The blades 108 may be any suitable blade capable of converting the kinetic energy of the wind into mechanical energy. In one embodiment, the blades 108 are made from a thin metal material, however, it should be appreciated that blades may be any suitable material including, but not limited to, a poly-carbon, a fabric, a synthetic material.
(19) The blades 108 may be fixed to the turbine rotor 104 in a static position. Alternatively, the blades 108 may be moveably attached to the turbine rotor 104. For example, a connection between the blades 108 and the turbine rotor 104 may allow the angle of the blades 108 to adjust in relation to the turbine rotor 104. The angle may adjust manually or automatically in response to the wind conditions at the location.
(20) The turbine rotor 104 provides mechanical energy for the one or more generators 112 as the turbine rotor 104 rotates about the axis 102. In one embodiment, a generator gear 128 is moved by a portion of the turbine rotor 104 as the turbine rotor 104 rotates. As shown in
(21) In an additional or alternative embodiment, the gear 128 may be a magnetic gear. The magnetic gear is a gear that moves in response to a magnetic force between the turbine rotor 104 and the magnetic gear. At least one of the gear 128 and/or the proximate portion of the turbine rotor 104 may be magnetized. Thus, as the turbine rotor 104 rotates proximate the gear 128 the magnetic force moves the gear 128 in response to the turbine rotor 104 rotation. The magnetic gear allows the turbine rotor 104 to rotate the gear 128 without any friction between the two components.
(22)
(23) The generators 112 may be located at various locations proximate the turbine rotor 104.
(24) The generator 112 may be any suitable generator for converting mechanical energy into power including, but not limited to, electric generators, motors, linear generators, and the like.
(25) In one embodiment, one or more of the generators 112 is a linear synchronous motor (LSM). The LSM motor may advance the turbine support 120 and may double as a braking system.
(26) The power generated by the generator may be fed directly to a power grid. Further, it should be appreciated that the power may alternatively or additionally be used on site or stored. The stored power may be used at a later date when demand for the power is higher. Examples of power storage units include, but are not limited to, batteries and generating stored compressed air, a flywheel system, a magnetically levitated flywheel system, hydraulic accumulators, capacitors, super capacitors, a combination thereof, and the like.
(27) The one or more magnets 110 reduce and potentially eliminate friction between the turbine rotor 104 and the turbine support 106. This friction reduction allows the scale of the wind turbine 100 to be much larger than a conventional wind turbine. In a conventional wind turbine the larger the wind turbine, the more friction is created between the moving parts. The amount of friction eventually limits the effective size of a conventional wind turbine. In one example, the wind turbine may have an outer diameter of 1000 ft. Known wind turbines prior to this invention typically have diameters of up to approximately 300 ft. In a preferred embodiment, a fixed wind turbine 200, as shown in
(28) Although, the overall size of the wind turbine 100 may be much larger than a traditional wind turbine, the amount of power one wind turbine 100 produces is much larger than a traditional wind turbine. Therefore, the total land use required for the wind turbine 100 may be reduced over that required for a traditional wind farm.
(29) The embodiment shown in
(30) The fixed wind turbine 200 may include an interior access way 202, according to one embodiment. It should be appreciated that any of the wind turbines 100, 200 and 304 may include an interior access way 202. The interior access way 202 allows a person to access the interior of the turbine support 104. The interior access way 202 may extend above and/or below the turbine rotor 104 in order to give the person access to various locations in the fixed wind turbine 200. The interior access way 202 may allow a person to perform maintenance on the magnets 110 and other components of the wind turbine 100, 200, and 304. Further, the interior access way 202 may have a means for transporting persons up and down the interior access way 202. The means for transporting persons may be any suitable item including, but not limited to, an elevator, a cable elevator, a hydraulic elevator, a magnetic elevator, a stair, a spiral staircase, an escalator, a ladder, a rope, a fireman pole, a spiral elevator, and the like. The spiral elevator is an elevator that transports one or more persons up and down the interior access way 202 in a spiral fashion around the interior of the interior access way 202. For example, the spiral elevator may travel in a similar path to a spiral staircase. The elevator and/or spiral elevator may use magnetic levitation to lift the elevator up and down.
(31) The upper portion 201 of the turbine support 106 may include an observation deck 204. The observation deck 204 may extend around the perimeter of the wind turbine 100, 200 and/or 304, thereby allowing a person to view the surrounding area from the observation deck 204. The observation deck 204 may also serve as a location for an operator to control various features of the wind turbine, as will be discussed in more detail below.
(32) The upper portion 201 of the turbine support 106 may further include a helipad 206. The helipad 202 allows persons to fly to the wind turbine 100, 200, and/or 304 and land a helicopter (not shown) directly on the wind turbine. This may be particularly useful in remote locations, or locations with limited access including, but not limited to, the ocean, a lake, a industrial area, a tundra, a desert, and the like.
(33) The upper portion 201 of the turbine support 106 may further have one or more cranes 208. The cranes 208 allow an operator to lift heavy equipment. The crane 208 may be a tandem crane capable of rotating around the diameter of the wind turbine. The crane may assist in the construction of the wind turbine 100.
(34)
(35) The wind compressor 400 may be any suitable obstruction capable of re-channeling the natural flow of wind towards the wind turbines 100, 400. Suitable wind compressors include, but are not limited to, a sail, a railroad car, a trailer truck body, a structure, and the like. Structurally the obstructions comprises a shape and size to capture and redirect a body of wind towards the wind turbine. In one embodiment an obstruction such as a sail, which comprises a large area in two dimensions but is basically a flat object, must be anchored to avoid displacement by the force of the wind. Other obstructions, such as the rail road car or trailer truck, should have enough weight to avoid wind displacement.
(36) Each of the wind compressors 400 may be moveably coupled to a transporter 403, or transport device to move the compressor 400 to a location or position that captures the wind flow as the direction of wind changes and directs the wind flow towards the wind turbine. The transporter may be any suitable transporter 403 capable of moving the wind compressor 400 including, but not limited to, a locomotive to move a rail car, a automobile, a truck, a trailer, a boat, a Sino trailer, a heavy duty self propelled modular transporter 403 and the like. Each of the transporters 403 may include an engine or motor capable of propelling the transporter 403. The location of each of the wind compressors 400 may be adjusted to suit the prevailing wind pattern at a particular location. Further, the location of the wind compressors 400 may be automatically and/or manually changed to suit shifts in the wind direction. To that end, the transporter 403 may include a drive member for moving the transporter 403. The transporter 403 may be in communication with a controller, for manipulating the location of each of the transporters 403 in response to the wind direction. A separate controller may be located within each of the transporters 403.
(37) One or more pathways 402, shown in
(38) In one aspect of this invention, the controller may be a single controller 404 capable of controlling each of the transporters 403 from an onsite or remote location. The controller(s) 404 may be in wired or wireless communication with the transporters 403. The controller(s) 404 may initiate an actuator thereby controlling the engine, motor or drive member of the transporter 403. The controller(s) may comprise a central processing unit (CPU), support circuits and memory. The CPU may comprise a general processing computer, microprocessor, or digital signal processor of a type that is used for signal processing. The support circuits may comprise well known circuits such as cache, clock circuits, power supplies, input/output circuits, and the like. The memory may comprise read only memory, random access memory, disk drive memory, removable storage and other forms of digital memory in various combinations. The memory stores control software and signal processing software. The control software is generally used to provide control of the systems of the wind turbine including the location of the transporters 403, the blade direction, the amount of power being stored versus sent to the power grid, and the like. The processor may be capable of calculating the optimal location of each of the wind compressors based on data from the sensors.
(39) One or more sensors 310, shown in
(40) It should be appreciated that the wind compressors may be used in conjunction with any number and type of wind turbine, or wind farms. For example, the wind compressors 400 may be used with one or more horizontal wind turbines, traditional vertical wind turbines, the wind turbines described herein and any combination thereof.
(41) Preferred methods and apparatus for practicing the present invention have been described. It will be understood and readily apparent to the skilled artisan that many changes and modifications may be made to the above-described embodiments without departing from the spirit and the scope of the present invention. The foregoing is illustrative only and that other embodiments of the integrated processes and apparatus may be employed without departing from the true scope of the invention defined in the following claims.
