The present invention relates to the field of electricity production, in particular to a machine and system for power generation through movement of water.

Generating electricity from water sources remains a dream of mankind for many centuries. For this purpose we used a variety of means, including water wheels and hydraulic turbines. Previous attempts to convert the energy of the tidal movement of water or currents into electricity required the use of large-scale systems, traditional generators and various types of turbines.

A disadvantage of the known technical solutions (for example, disclosed in US 5440176) is the fact that currently used systems are difficult to configure for specific needs, they require large-scale structures and not always profitable. They are not suitable for fast transfer to another location, are not readily adaptable from the point of view of topography, and unable to resist corrosion caused by water. The weight of conventional generators with magnets and copper wire prevents their rapid replacement. In addition, there is still no system that would use a group of small power generating electricity (electricity generating) units, which placed the parallel to each other, converting the energy of ocean waters, rivers or other water flow into electrical, combining a relatively low-power generators into one large system of electricity production on an industrial scale.

Accordingly, in General, the present invention is the task of creating low-cost machines and systems, which would use a group of small capacity power generation units that could be accommodated parallel to each other at the same time electrically connected and interchangeable. In one embodiment, this is achieved by the proposed modular design, in others through the use of magnetic elements on the basis of magnetopolaron or rare earth metals, allowing to reduce the weight of the device and reduce the cost of their production, particularly suitable for the replacement of modular structures.

Based on the foregoing, the present invention proposes a machine for power generation through movement of water that contains a lot of electricity generating units that are installed with the possibility of receiving kinetic energy from moving water and convert the specified energy due to the motion of the turbine in each electricity generating unit. Moreover, electricity generating units electrically interconnected and arranged as in himosareena modules (with the possibility of replacing the faulty power unit without interrupting the production process of the whole machine power).

In another embodiment, a machine for generating electricity includes a housing with electrically conductive windings are accommodated in the housing impeller with magnetic elements on the basis of magnetopolaron or rare earth metals, generating induced electricity during the rotation of the impeller in the housing, and located on the impeller blades for receiving water from the kinetic energy, and the impeller is driven by the movement of water through these blades.

Another object of the invention is a system for power generation through movement of water containing many turbines, impellers which contain magnetic elements on the basis of magnetopolaron or rare earth metals, surrounded by electrically conductive windings are accommodated in the housing around the impeller, and are driven by the movement of water, generating electricity, and a turbine arranged in modular construction and electrically connected.

In another embodiment of the proposed invention in a system for power generation through movement of water contains a lot of electricity generating units that produce individually less than 5,000 watts of electrical power, and lock the tray to hold the electricity generating units, ensuring their electrical connection with one or ascoltami electricity generating units, which are preferably ordered arrays as arrays (matrices), placed in the ocean vertically and crosswise to the direction of tidal currents of the ocean and are electrically connected to the electric network and installed with the possibility of replacement of each electricity generating unit without interrupting the production process of the electricity system.

To generate electricity from water flow (waves, currents, tides, tides, etc. are used turbines. Independently rotating in a tapering nozzle, turbine wheel extracts additional energy from the flow of water past the other independent turbine wheel. The blades of the impeller of the turbine rotate inside the housing containing the coil, made of copper, conductive polymer or other conductive material. The rotating magnetic field produced by magnetopolaron, powder materials, generating a magnetic field, suspended in a homogeneous or heterogeneous polymer or conventional magnetic materials such as Fe, Co, Ni, Gd, Sn, Nd, or ceramics that generate a magnetic field generates electrical energy when the independent rotation of the turbine containing magnetic material within the conductive winding. Magnetopolaron differs in that its magnetic characteristic exists on the volume level, in contrast to the mixture of particles that are suspended in the polymer. Frame structure in polymer housing consists of a polymer or polymer reinforced with fiberglass, carbon fiber or polymer reinforced with carbon nanotubes. This frame serves as a support for the Central shaft of the turbine rotor inside the polymer shell of the turbine. Electric power produced by each turbine must be in the range from 0.001 to 5000 watts, but can also reach values of the order of 100,000 watts on the turbine. The electric current is removed from the winding of the turbine and using parallel connection is served on made from copper wire or conductive polymer conductors located inside the housing of the turbine. Internal conductors of an electrical current passing from one of the turbine casing to the next, until it reaches the collection system of electricity used to measure its power and onward transmission to the electrical network. If a separate generator produces from 0.001 to 100,000 watts of power, then the set of generators connected in parallel group by type two-dimensional array (lattice or matrix), can generate electricity on an industrial scale by a power of the order of several megawatts (MW). Because such systems are made of polymer clay is s, ceramic or non-ferrous metals coated, and all potentially magnetic part of the design of the turbine is not in contact directly with water, such systems do not corrode, are lightweight, are portable, cheap to manufacture and replace, and can easily be installed on any terrain. In addition, modular (mesh) the design of the array of energy generating units allows the repair and maintenance of turbines, without disabling the entire array. In fact, at any given time of operation can be withdrawn only a certain amount of generating capacity, as when maintenance or repair of one or another of the turbine shutdown to be only a single vertical set ("riser") electricity generating units or units included in a two-dimensional array, in which the turbine is located.

Below is a detailed description of the preferred embodiments of the invention. You must understand, however, that the invention may be embodied in various forms. Thus, the specific technical details of which are disclosed below, should be interpreted not as ohranyayuschie the possibility of carrying out the invention, but rather as illustrative material showing a way to use the present invention in virtually any specific design or virtually any way.

Figure 1 presents a graph illustrating the dependence of the average speed of 10 current from a depth of 12 sea in the deep zone of the ocean. It can be noted that the average flow velocity in the deep ocean areas between some upper and lower limits is relatively constant, which in some cases allows you to use this movement of water as a power source in accordance with the present invention. Examples of permanent deep-water currents is, in accordance with the present invention discussed below, it may work a lot of electricity generating units are Gulf stream in the Atlantic ocean and the Kuroshio current in the Pacific ocean. However, in the deep areas of the ocean to harness the energy of water is hard, as well as to serve arrays electricity generating units. Area of breakwaters, reservoir, no power plants, river or water conveyance structure more appropriate to achieve the advantages of the present invention and economic benefits from its implementation.

Figure 2 is a graph illustrating the dependence of the flow velocity of 20 from the depths of 22 sea in the area of the breakers of the ocean. It can be noted that with decreasing depth, i.e. the closer the waves to the shore, the water flow becomes faster, scattering is contained in the wave energy. This gives ready-to-use and renewable energy source for an array of energy generating units covered in this type description. The following descriptions will be clearly shown that this phenomenon contributes to the creation of the shoreline systems of energy extraction described in this description to get cheap and reliable energy. This method will work for any moving body of water, with a relatively constant the current velocity at a given cross-sectional area.

Figure 3 shows a group of 30 arrays electricity generating units constructed in accordance with the preferred embodiment of the invention. A group of 30 arrays consists of a sequence of individual arrays 34 installed in the area of breakwaters parallel to the shore 32 for receiving the energy of tidal currents. Such arrays can be placed across the river, in the deep parts of the ocean and in other places where their location allows you to use the energy of movement prevailing in this place water flows. Each array 34 is a sequence of linked in one way or another electricity generating units, which are driven by the movement of the water passing through them. Electricity generating units are electrically interconnected through the backplane block or chassis (see Fig) so that each group of 30 arrays produces electricity, equal to the amount of electrical energy generated by each of the electricity generating units. Ultimately, the group of 30 arrays connected to the electrical network.

Figure 4 shows a side view of one set of 40 electricity generating units 42, forming part of an array of a larger size, for example, shown in figure 3. Figure 4 shows one set of 40 electricity generating units 42, which serves to accept the power unidirectional flow of water deep part of the ocean, rivers and even the ocean areas of breakwaters. When the water passes through the electricity generating units directed to the left arrows 44 electricity generating units 42 convert the kinetic energy of water into electricity. Individual electricity generating units 42 are arranged in a set and electrically connected to the positive and negative poles 46, generating electricity, which is transmitted via line 49 to the inverter or the power grid. Each individual electricity generating unit 42 capable of producing a small amount of power, but sets 40 electricity generating units 42, connected in parallel, produce large amounts of electricity. Set 40 electricity generating units may be moored to the ocean bottom anchor 48 by conventional means, well known in the art. These arrays are flexible and float in water, while lying across the flow of water for maximum energy production.

A significant advantage of the modular construction of arrays of electricity generating units is the use of small power units, which according to a preferred variant embodiment of the invention can have an output power generated by an energy of the order of 0.001-5000 watts. This allows us the device, which can be significantly less than typical turbine power units, having a volume of about one-thousandth from the volume, namely 3 to 50,000 cubic inches.

The use of such small devices can ease the creation of large arrays of electricity generating units, and allows at any time to quickly replace a malfunctioning device without interrupting the process of producing electric energy. Such miniature power units can be called generators or microanalyzer. The combination of many such devices in the array gives the aggregate energy equal to the energy generated by one much larger generator.

Figure 5 shows one set of 50 electricity generating units 52, used for maximum energy use of bi-directional flow of water in the zone of the breakwaters. When the water passes through the electricity generating units on the arrows 52 and 54 towards the left and the right, power generation units 52 convert the kinetic energy of water into electricity. The water flow may be associated with the high tide and low tide and, therefore, can quickly change direction, powering electricity generating units, made and installed in such a way as to absorb the kinetic energy of the water flow from two different e.g. the areas. Figure 5 shows a side view of one set of 50 electricity generating units 52, forming part of an array of a larger size, for example, shown in figure 3, and electricity generating units electrically connected with each other, the positive and negative poles 56 just as it was shown in figure 4.

Figure 6 depicts a side view of one of the impeller 60 of the turbine with multiple blades (see Fig.7)used to convert the kinetic energy of the water flow into electrical energy. In the device of the individual power generation units are electrical connectors 64, allowing parallel to combine these units into a single electrical network that allows you to summarize your energy output. The impeller 60 (or turbine) is located in the case made accordingly to generate electricity. To give the case the rigidity it has cross braces (shown in Fig.7). Electricity generation is due to the location of the magnets or magnetic materials in the shell of the blades of the impeller of the turbine and the location of the winding in the case of the impeller 60 of the turbine. Under the influence of water flow impeller 60 of the turbine is driven into rotation, creating an electromagnetic force, inducing a current in the windings and thereby vyroba what they electricity. Due to the parallel connection of the electric circuit of electricity generating units small amounts of electricity generated by the individual elements are combined to produce electrical energy great power.

In a preferred embodiment of the invention using conventional means of production of polymer products can be made of the turbine and the housing, in which instead of the standard magnets and copper winding magnetic polymers or magnetopolaron. The number of magnetic polymer or magnetovolume and its location in the body is determined by the degree of magnetic attraction is necessary in a particular case. Through the use of these materials is achieved by the magnetic field strength and magnetic permeability, sufficient for the generation of the required power, and as a result we obtain the generator, which has a light weight and corrosion resistance under the action of water.

A single turbine can be equipped with independent blade rims 66 that allows you to shoot with the turbine most of the work along its longitudinal axis, and the turbine may be called by the outer surface 68 that allows you to increase the speed of flow due to narrowing of the turbine nozzle.

Figure 7 depicts the end view on to bus 70 of the turbine and the impeller 72 with multiple blades 74, allows you to take away from moving water maximum energy. Cross braces 76 provide enhanced rigidity of the hull.

On Fig shown unification block 80 which is used for mounting a variety of electricity generating sets blocks to create arrays of larger size, shown in figure 3. Unifying unit 80 provided with channels positive 82 and negative 84 contacts for connecting the sets of power-generating units. The joint unit is installed, each group arranged vertically electricity generating units. The first vertical set of 85, the second vertical set 86 and the N-th vertical set are placed next to each other, including in the circuit in parallel through contacts 82 and 84, and adjacent sets of power-generating units are connected in a common electrical circuit through its grounds. As you can see in the unification block 80 can be placed a lot of vertical electrical generating sets blocks, electrically connected to each other. Thus, it is possible to create arrays of any number of vertical sets ("risers"), which, in turn, any number of electricity generating units that are dictated only by the characteristics of the set of application tasks. On top of multiple power generation units can be installed is on the polymeric transmitting plate, that allows you to increase the electricity generating sets blocks, combine them into a single electrical circuit and to transmit the electric current from the array to the rectifier/inverter, and then to the external electrical network. This scheme provides for quick installation and easy repairs.

On figa shows a perspective view of the array 92 of electricity generating units, oriented to pass through the water flow on the ocean side 94 or 95 shore. This location of electricity generating units allows each block to the maximum extent to convert the kinetic energy of the flow of water at high tide and low tide. In this design the individual power generation units is oriented either in one or in the other direction, and the turbine rotate at optimum speed when the water flow is supplied to them from the appropriate direction.

On figb shows a side view of a set of electricity generating units, electrically interconnected described manner and thus arranged to receive the kinetic energy of the streams of water coming from two different directions. Preferably, the sets were attached to a strong, but light housings 95, capable of resisting the flow of the ocean the odes and maintain structural stability in adverse weather. An array of power generation units can be mounted on the bottom of the ocean armature 97, which provides additional structural stability. To maintain a given position of the structure and to determine its location in the water can be used a float or buoy 98. Preferably, the electricity generating units were mounted on the backplane blocks separate sets with the formation of the array and further combined into a single electrical network, jointly developed electric energy transmitted to the external sources of consumption. The total energy produced by the array of power-generating units, can be transmitted to the external electrical network as in conventional electric wire 99, and superconducting cables or other means of transmission of electrical energy, known at the present time.

On figa, 10B, 10B and 10G presents several images of the turbogenerator conical shape with a Central shaft 100 and many of the blades of the impeller, located around the circumference of the shaft several steps, such as step 102. In some embodiments of the invention, it is preferable to use a single-stage impeller. The body of the impeller of the turbine contains built into it the magnets 104 or embedded magnetic polymer. Externally the second housing 108 of the turbine contains passing through electrical leads 106 and a rigid support 107, allows you to mount a set of separate units. On Figg also depicts the unification block 111, which serves for mounting and connection in a single electrical circuit arrays electricity generating units. Unifying the unit contains electrical connections made of copper wires or conductive polymer 109.

The innovative design of the turbine is obtained through the use of polymers used in the polymer forms for mass production of turbines. Magnetic elements of the turbine can be one of various materials that are embedded in the turbine, including iron, ceramicbased, magnetic polymer (magnets based magnetopolaron) or magnets rare-earth (NdFeB). The use of conducting polymer for the manufacture of cathodes and anodes embedded in the design of the transmission system and its arrays reduces the overall weight of the device and allows you to make the manufacture of turbines effective and low-cost. In addition, the use of such turbines does not result in emissions of CO2, CO, NOx, SOx, or ozone precursors. Turbine wheel depicted in figure 10, made of polymer for maximum work in tandem with tapering body or nozzle.

Polymers are used to achieve corrosion resistance, low is th cost of production, mass production of the blades of the impeller of the turbine, the production of multiple independent from each other impellers of the turbine. Polymers are used to produce plastic molds for mass production of turbines. The polymers used, such magnetic elements, as iron, ceramicbased or magnetic polymers (magnets based magnetopolaron and NdFeB rare earth metals)that allows them to convert the kinetic energy of the ocean into electricity. In addition, conductive polymers used for the manufacture of cathodes and anodes embedded in the design of the transmission system and its arrays.

On figa and 11B are side and front/back of the turbo-generator with multiple impellers arranged in several stages. In some examples, the constructive embodiment of the invention for the release of energy may be preferable to use a single-stage impeller turbines. The turbine is mounted on connected to a single electrical circuit of the base 111, which allows vertically to collect several power-generating units that are part of a large array of building these blocks vertically. Cross braces 112 provide additional stability to the housing turb the us. The windings of a turbine casing of copper wire or conductive polymer located around the impeller and turbine are used to generate electrical current when the magnets or magnetic material embedded in the impeller rotates with the impeller, creating a flux of magnetic induction.

On Fig shows a group of arrays 120 electricity generating units, electrically connected to the network 122. Arrays of electricity generating units installed at right angles to the direction of flow of ocean water and is included in the network in parallel. On top of the arrays provided by the floats (buoys) 124 that support arrays in a predetermined position and orientation, and are used to determine their location in the water. In a preferred embodiment of the invention, arrays of electricity generating units are located close to areas of breakwaters to use the maximum amount of energy of ocean waves near the shoreline.
