The invention relates to an apparatus for generating electricity, which is driven by the flow of water, such as sea, tidal wave or river.

In recent years, much attention has been paid to renewable electricity intended for home and commercial use. Traditional methods of electricity generation, such as coal-fired thermal power plants for the generation of electricity emit large amounts of harmful gases such as carbon dioxide. Renewable electric energy received from the sun, wind and water, is used around the world, but not widely spread in many countries.

Power plants, for which as an energy source to generate electricity is used the flow of water, often require a dam or other similar man-made structures across the natural flow of water. Associated costs and infrastructure requirements can be considerable, in addition, has an adverse impact on the environment, such as excessive siltation of the reservoir due to slow flow and spill reservoir above the dam.

Power plant running on a tidal wave, without the use of dams and other artificial. the, during the tidal cycle are exposed to water currents of varying strength. Some installations proposed for these purposes in the prior art, is not effective at low flow rates of water that occurs during the cycle of the tide-the tide is low, and, accordingly, can work effectively not more than 50% of the tidal cycle.

The technical task of the present invention is to provide a setting that is able to more fully utilize tidal otlivnyy cycle for energy production.

According to the invention provided with the installation to generate electricity from the flow of water, comprising: a housing with an inlet for water and release water, a turbine mounted in the housing for rotation around a Central axis, containing the turbine shaft and many paddles, while the body is made with possibility of installation in water and are made so that water flows into the housing through the inlet, and, basically, is sent to a worker thread for the turbine, and then sent for release through the release; and the turbine is equipped with a control mechanism blades, made with the ability to control the angles of the blades in relation to the work flow so that each blade rotates about a respective axis with a speed of rotation equal to half the speed of the turbine shaft due to which a large area on which ernesti blades facing the incoming flow of water, to drive a turbine in a given direction of rotation, and a smaller area on the surface of the blade facing the incoming flow of water, opposite to the direction of casting, and the installation further comprises a partition, which runs almost from the Central axis to the side of the casing, through which each blade moves when handling smaller surface area, to facilitate direction of the working thread around the side of the casing, through which each blade moves when handling larger surface area of this blade.

In a preferred embodiment of the invention the apparatus comprises an additional turbine, comprising a shaft (secondary shaft) and multiple blades (extra blades), and equipped with an additional mechanism to control the angle of the blades in a turbine mounted in the housing adjacent the said turbine for rotation around a Central axis parallel to the axis referred to the turbine, while the body is made so that the incoming water flow is mainly directed at two worker threads, one for each turbine, with an additional mechanism to control the angle of the blades is arranged to control the additional angles of the blades in relation to the working the stream for additional turbine so that each complement the other blade rotates around the axis with rotation speed, equal to half the speed of rotation of the additional shaft of the turbine, due to which a large area of the surface of the blade facing the incoming flow of water, to bring into force an additional turbine in a given direction of rotation, and a smaller area on the surface of the blade facing the incoming flow of water, opposite to the direction of bringing additional turbine, the installation further comprises an additional wall, which runs almost from the Central axis to the side of the casing, through which each blade moves when handling smaller surface area, to facilitate direction of the working thread around the side of the casing, through which each blade moves when handling larger surface area of this blade.

In the preferred embodiment, two turbines coupled and synchronously rotate in opposite directions, and the incoming flow of water is directed to the outer periphery of each of the turbine where the flow of water is reversed, a large area of the surface of the blade. Two turbines are adjacent to each other of the inner peripheral parts, where the incoming flow of water is reversed smaller surface area. This not only minimizes the impact of the incoming flow of water on the inner peripheral part (which could act back to the impact of incoming what about the thread on the outer peripheral part), but also prevents the collision in this area of the blades of the two turbines.

Preferably, in the inlet water was provided a deflector that directs the incoming flow of water in two threads of execution directed to the appropriate external parts of the body.

Preferably, the control mechanisms of each blade of the turbine operatively control the angle of the turbine blades so that the motion of each blade through the Central part of the body forward exhibited less surface area to reduce the reaction force acting on the corresponding turbine in the Central part, and to prevent a collision in the Central part of the blades of the two turbines.

The control mechanism angle of the blades or each control mechanism angle of the blades preferably includes a planetary gear system having a wheel-satellites, each of which is associated with a corresponding one of the blade and with a fixed sun gear, the axis of which coincides with the axis of the turbine, with which wheel satellites engages with the rotation of the turbine blades rotate, changing its angular position.

In one embodiment of the invention, the body relies on a floating structure and/or is part of it. In this embodiment, in the assembled condition, the installation of the floats in the water with the blades of the turbines, have been recovered from the part below the water surface.

In another embodiment of the invention the housing in the installed state of the fixed anchor way near the water layer. In this embodiment, the housing may contain a swimming system to deliver the installation in the desired location on the water, and then immerse in water and set on a layer of water or near the water layer.

In these embodiments, the generator(s) is(s) above the surface of the water. In the version where mounted installation floats in water, generator, or each generator can be located on the floating structure. In the version where the frame is immersed in the water layer, the generators can be mounted on poles or towers, projecting from the casing or from the bottom above the level of the surface of the water during high tide.

Turbine or turbines can operate several separate generators or one generator. Preferably, the installation contains one or more hydraulic pumps driven turbine or each turbine and the pump or pumps associated with one or more hydraulic motors that drive the generator. Also, as an alternative, you can use other types of drive between the turbine and the generator (generators), such as direct mechanical drive.

Although installation is best suited for tidal stream, it is also possible to apply the La unidirectional flow, in which due to seasonal changes in certain periods of slow flow rate. If the unit is designed for tidal power plants, because the water flow periodically reverses direction on the opposite, the water intake and outlet will be reversed, and the blades must be suitable for operation in conditions of bidirectional flow.

Preferably, the installation was modular, allowing you to create a power supply system the power required by assembling two or more modules.

Now will be described the preferred embodiments of the invention only as an example and with reference to the accompanying drawings, on which:

For convenience of presentation preferred embodiments of power plant will be described with reference to the application in the marine environment, in particular in the tidal estuary or Bay. However, it should be understood that the applicability of the invention is not limited and is applicable to most cases, when the energy source is natural stream of water such as a river, estuary or other water stream.

Power plant 10 (Fig.1-4) contains two turbines 12, 14, each of which is attached to one of the generators 16, 18, and the turbine 12, 14 are located inside the housing 20. Flowing through the housing 20, the water acts on the blades 22 of the turbine and drives the turbines 12, 14, producing electricity.

The housing 20 includes a receiving water 24, the outlet 26 and the turbine compartment 28. Inside of recipient 24 is a deflector 30 adjacent to the turbine compartment 28 to divide the flow of water 32 from the recipient 24 two worker threads 34, 36, one for each of the turbine 12, 14. Each thread 34, 36 are sent to the outer end or edge of the turbine compartment 28 so that the turbine 12, 14 rotate in opposite directions. Then the water flow out of the housing 20 through wodoview what to 26 in the form of the output stream 40. The direction of flow to the outer portions, or edges, of the turbine compartment 28 also contributes to a stationary wall in the Central part of the body, which will be described later.

The turbines 12, 14 rotate synchronously in opposite directions and are adjacent to each other, and the angular position of the blades 22 is guided in rotation, so that the blades 22 put forward a large surface area for the incoming stream 32 in the direction of rotation of the turbine, and for opposing the incoming stream 32 is smaller surface area. The blades 22 are evenly arranged around a Central axis and attached to the shaft 44 of the turbine through the support structure, consisting of upper and lower bearings 46, between which the blades are mounted so that each blade can rotate relative to the supports 46 around the Central vertical axis of the blade. The mechanism 48 control the angle of the blades associated with the blades 22 so that rotation of the blade 22 relative to the supports 46 is controlled with the ability to change the angular position of the blade 22 when the rotation of the turbine. The blades 22 rotate around their axes with speed equal to half the speed of the turbine shaft, and each blade 22, in essence, is perpendicular to the worker 34, 36 water near the outer edge of the turbine compartment 28 and parallel to the entrance is the overarching flow of water, when it is near the center of the turbine compartment 28, and therefore adjacent to the corresponding blade of the other turbine. The rotation of the blade 22 allows a significant part of the workflow 34, 36 were in contact with the region of the blade 22 a large area near the outer edges of the turbine compartment 28 and that the minimum flow of water was in contact with the surface of the blade 22 small area in the Central part of the turbine compartment 28, which, of course, causes the turbine force counteracting the force of water flow; this counterforce, however, is rather small due to the configurations of the flow and the blades. The rotation of the blades 22 also prevents the collision of two turbines 12, 14 in the Central part of the compartment 28 when the peripheral parts of the two turbines are located closely.

The housing 20 allows you to install the turbines 12, 14 in the incoming water stream 32 without the need for additional facilities type dams, while capturing and directing the flow of water required to operate the turbines 12, 14. You can also attach to the body of the fence from floating debris, consisting of metal rods and passing through the water intake 24 and outlet 26 so that the blades 22 of the turbine are protected from damage by large debris such as floating logs. Fencing from waste also will not allow big mo is a mere animal, such as dolphins or whales, to get in the turbine compartment, thereby reducing the risk of injury or death of marine animals and damage to the turbines 12, 14.

In the present embodiment, the recipient device 24 and outlet 26 allows the use of the installation 10 in terms of a bidirectional flow, such as tide and low tide. In such cases, the recipient 24 for one direction will be the outlet 26 to reverse direction and Vice versa. Accordingly, the outlet 26 has a second baffle 38, designed to separate and flow direction of water current in the opposite direction from that shown in the drawing. However, this option is implementation - perhaps with some minor changes - applies to unidirectional flow, such as flow in the river.

Stationary wall 49 is placed between the upper and lower supports 46 of the blades and extends vertically, essentially the entire length of the blade, almost from the Central axis of the turbine and to the Central part of the turbine compartment 28, contributing to the direction of the workflow 34, 36 water around the respective outer portions, or edges, of the turbine compartment 28 and to minimize flow through the Central part of the turbine compartment 28.

The blade 22 shown in the drawings in the form of flat strips, however, it should be understood that this selenodesy illustrative purposes, and the actual shape of the cross section of the blades 22 will depend on many factors and may differ.

As described previously, the mechanism 48 control the angle of the blades rotates the blade 22 relative to their supports 46 and relative to the main shaft 44 of the turbine. 4 shows a variant implementation mechanism 48 control the angle of the blades, in which a stationary sun gear 51 is connected with revolving wheels-satellites 52, one of which is attached to the shaft of each blade 22 by means of a suitable binder system 54, such as a belt, chain or the number of spurious gears. Alternatively, a sun wheel 51 and the satellites 52 can enter into direct mutual engagement. Its final drive ratio must be such that the blade 22 is completely turned around its Central vertical axis for every two full revolutions of the turbine.

In the present embodiment, the turbine 12, 14 are attached to the generator 16, 18 through a hydraulic system comprising a hydraulic pump driven turbine connected to the hydraulic motor, which drives the generator 16, 18, but can be installed between the turbine and the generator and other systems; in addition, both the turbine can operate one common generator. Electricity, verbatim is radiated by the generator 16, 18, is fed into the power grid or local distribution network through cables that are not shown on the drawings.

Figure 3 presents the energy system 10 installed on the seabed 55 on stilts 56. In a preferred embodiment, the unit also includes additional boats 58, so that the installation can be brought to the tow vehicle, and then lowered to the seabed 54. The bottom of the housing may be raised at site 57, where the incoming stream 32 water facing side of the blade, having a large area. This reduces leakage of water around the lower part of the blade and create a sump 59. Silt or sand trapped in the body, under the action of rotation of the blades 22 and the flow of water 34, 36 will be pushed out of the raised section 57 of the tank 59. In addition, when the water flow is not strong enough to rotate the blades of the turbines, silt, and sand will tend to settle in the lowest part of the hull.

In an alternative embodiment of the installation (Figure 5), the power system 10, generally similar to that described above in relation to Figure 2 and 4, contains the craft 60, allowing it to float at the surface or near the surface 62. In this embodiment, silt and sand entering the installation, can exit through the outlet opening 64 in the bottom of the power unit 10. Protective is described from floating debris also has and continues from the top of the vessels 60 to the bottom of the water intake and discharge energy installation 10, preventing the turbine logs or large marine animals.

Figure 6 shows a system 70 of the power supply formed of three modules 72, 74, 76, each of which is constructed on the basis of the above installation 10. Inside the modules 72, 74, 76 have the same characteristics as above described power unit, shown in Figure 1-5, and the outer part of the module body adapted for connection with other modules. This allows you to build a power plant of a given capacity of two or more adjacent to each of the modules parallel actions.

Figure 7 presents an alternative implementation of the control mechanism the blade angle. It is illustrated in relation to the turbine 100, the basic design of which is similar to that described above, having four blades 102A, 102b, 1 0 2, 102d. The blades 102A, 102b, 1 0 2 and 102d connected to the turbine shaft through the support structure 104. Each blade lasts approximately at the height of the turbine casing and can be rotated attached to the support structure 104 only in the upper end.

Mechanism 107 control the angle of the blades is provided in the form of the guide 109 is cylindrical in General form, continuing from the Foundation of the building to the upper part of the body, preferably according to one of embodiments, a little below the support structure 104. Guide 19 also contributes towards the current workflow 106 water around the outer periphery of the turbine, acting as partitions, effectively preventing substantial flow of water through the Central part of the turbine casing. The rollers 108 or other siteplease elements attached to the inner edge of each blade can be moved at least along the section of the guide 109 so that the guide controls the angular position of each blade relative to the water stream 106, at least at the site of the turnover of the turbine, especially when the blade is moved through the outer part of the body where the flow of water is reversed in its high surface area. The connection point of each blade with a support structure 104, and hence, with the axis of its rotation, is separated from the Central axis of the blade closer to the outer edge, so the forces acting on the blade side of the incoming water flow, move the blade so that the rollers 108 forcibly injected into engagement with the guide rail 109 by shifting it through the inlet area of the housing to the exterior of the housing, as shown in Fig.7. for blades 102d, 102a.

Power workflow 106 of the water acting on the blades, the turbine rotates and presses the rollers 108 to guide 109 until the blades will not accept the position shown for the blades 102A. In this position, further movement of the rollers 108 along the guide 109 is limited by the limiter 110 in the form of a ledge napravlyayus the 109. The worker thread 106 water continues to provide a torque force acting on the turbine, but because the turbine, and hence the supporting structure 104 of the blades is rotated, the blade 102A as a result of this limitation stronger tilts relative to the flow of water, while its inner edge will not be ejected from the limiter 110. At this point the blade 102A "jumps" in the position in which the blade 102b, essentially parallel to the flow of water due to the effect of the vane caused by the displacement of the center of rotation of the blade. Upon further rotation of the turbine blade due to this effect will remain almost parallel to the water flow, as shown for blade 102b and 1 0 2.

Essentially, the blades alternately remain nearly perpendicular to the working flow of water 106, being near the outer edge of the turbine compartment 100, and almost parallel to the flow of water when they are near the center of the turbine compartment, i.e. near the respective blades of the other turbine. The rotation of the blade 102 allows to provide a contact a considerable part of the thread 106 of the water with the blade near the outer side or outer edge of the turbine compartment and to minimize the contact of water flow with the blade in the Central part of the turbine compartment. When moving the blades to the intake zone of the incoming flow of water pushes it inside edge back to aiming the th 109, in such a way that the remaining part of the rotation of the blade rollers 108 which engage with the guide as shown for the blade 102d.

Although there have been described preferred embodiments of two adjacent to each turbine having a vertical axis, to create energy installed in the housing can be installed only one turbine according to the invention.
