The device relates to the field of small hydropower, and more particularly to devices for energy conversion Coriolis flow of water and energy waves.

A device for wave energy, containing the support and the energy Converter of the water, made in the form of multiple bladed turbines connected in garland (see U.S. patent No. 4333311, IPC F 03 13/12, born 08.06.1982).

However, this device allows you to use only the energy of wind waves.

The closest analogue is the device to use energy water stream containing a support and an energy Converter made in the form of a hollow cylinder with vanes (see UK patent No. 2302142 And, IPC F 03 3/14, 08.01.1997).

However, this device allows you to provide only the energy of the water flow.

The objective of the invention is the ability to effectively use the energy of water flows at any depth and energy of the waves.

This technical result is achieved due to the fact that the hydrodynamic device (GPP) for the energy of the water stream contains energy Converter that directly converts the energy of the translational motion of water flow into kinetic energy of rotation and consisting of one or more sequentially connected in garland turbines, each the I of which is made in the form of a hollow rotor shaft is a cylinder with a cone fairing on the grounds attached along the shaft of the cylinder or at some angle thereto, the blade is semi-cylinders, so that the bearing shaft-cylinder fits into the inner ends of the blades of the semi-cylinders and their outer ends are tied together in several places along the length of the turbine narrow rings, hoops, form a multi-cylinder, with variable buoyancy, adjustable ballast in the hollow part of the shaft of the cylinder so that the turbine could be immersed in water or come out of it on the third corps, which is installed between the supports and connects one or both ends by means of shafts of the variable or fixed length through a flexible (cross) connections, couplings and transmission systems with actuator systems placed on the supports or the banks; system actuators are used to provide energy transfer from the energy Converter to the consumer and consist of one or several series-connected through a clutch and transmission systems, the massive inertia of the flywheel spins up the energy Converter or combined and executed in the form of a disk or drum, or cylinder, connected by couplings and transmission systems with energy consumer of rotation. System actuators may be located on NEPAD is the author of the support and are connected to the adders, transmission and clutch with multiple threads converters of energy radiating from the support, the second ends of which are wound on point supports or rafts anchored. Also, the system actuators may be located on boat anchored and made in the form of a circular object with a hemispherical surface part and underwater stabilizer provisions of cylindrical shape having a layered structure, on one of which there are several Autonomous inputs for connection of actuators with energy converters, the second ends of which are wound on point supports or rafts anchored.

The invention is illustrated graphic material.

Hydrodynamic device to use energy water stream contains energy Converter (1, 2)directly converts the energy of the translational motion of water flow into kinetic energy of rotation and consisting of one or more sequentially connected in garland 9 (3) turbines 6 (3), each of which is made in the form of a hollow bearing shaft-cylinder 3 (Fig 1, 2) with a conical fairing 2 (figure 1) on the grounds attached along the shaft of the cylinder 3, or at some angle thereto, the blade is semi-cylinders, 5 (1, 2) such a way that the bearing shaft-cylinder 3 fits into the inner ends of the blades of the semi-cylinders 5 and their outer ends are tied together in several places along the length of the turbine 6 narrow rings-hoops 4 (1, 2), form a multi-cylinder, with variable buoyancy, adjustable ballast in the hollow part of the shaft of the cylinder 3 so that the turbine 6 could be immersed in water or come out of it on the third corps, which is installed between the supports 7 (figure 3) and is connected to one or both ends by means of a shaft 18 of a variable or fixed length (figure 4) through a flexible (cross) compound 21 (figure 4), the coupling 15, 19 and the nodes of the transmission system 16, 17 (figure 4) with actuator systems, 8 (3)placed the on the supports 7 (figure 3) or the banks; system actuators 8 are used to provide power transmission from the turbine 6 (7) to the consumer 34 (Fig.9) and consist of one or several series-connected through coupling 15, 19 (Fig.7-9) and gear system 32, 35, (Fig, 9) massive inertia of the flywheel 14 (4, 7-9), drives the energy Converter or combined and executed in the form of a disk or drum, or cylinder, connected by a coupling 15, 19 (Fig.9) and transmission 35 (Fig.9) with the energy consumer of rotation 34 (Fig.9). System actuators 8 may be located on the fixed bearing 7 and is connected via the adders 28, transmission and clutch 15, 19 with several garlands 9 (thread) energy converters diverging radially from the support 7, the second ends of which are wound on point supports 10 or rafts 11, anchored, 23. Also, the system actuators 8 may be located on boats 22, anchored, 23 and is made in the form of a circular object with a hemispherical surface part and underwater stabilizer position 25 of cylindrical shape having a layered structure, on one of which there are several Autonomous inputs for connection of actuators 8 energy converters, the second ends of which are wound on point supports 10 or rafts 11, fasting is undertaken on the armature 23.

Gas-dynamic device operates as follows.

The turbine 6, which is a third body (cylinder formed by the blades) on the surface of the water, there are two forces (figure 2): the power of the water flow and pressure waves 1, creating a unidirectional torque of the turbine 6. The thread is constantly acting on the blade 5, located at the bottom, below the sole of the waves, and the waves on the rest of the blade 5. When lifting wave 1 presses on the concave surfaces of the blades 5 on one side of the turbine 6 and surrounds the convex on the other. In the differential resistance occurs the moment of rotation, with unidirectional torque from the stream. When the recession wave 1 functions on either side of the turbine 6 is changed to the reverse, keeping the unidirectionality of the rotation. The direction of rotation of the turbine 6 also does not change if the stream is to act with the opposite hand. Therefore, the turbine 6 can work effectively not only on unidirectional flows of rivers, but also on the currents of the tide, without changing the direction of rotation. Moreover, the efficiency of the turbine 6 will be much higher if the turbine 6 are immersed in the flow completely. Then the work will involve not only the bottom of the blade 5 when the turbine 6 was on the surface but also the side. That is, about half of the blades 5 of the turbine 6. If this is m rotation will be effected with minimal slowdown from the second half of the blades 5, not involved in the work. However, the turbine 6 in this case should be immersed below the level of low tide and below the sole of the waves under strong excitement during low tide. Then there would be a reliable operation of the upper half of the turbine 6 at low tide in any weather. On the rivers of the deep position of the turbines 6 will retain their performance in the winter, during freeze-up and will not impede the navigation of the free water.

To increase the power on the shaft 3 drives the turbine 6 are connected sequentially flexible (cross) connection 21, forming (thread) garland 9. The converters in the form (threads) garlands 9 is placed between the supports. The supports can be and the coast, and coastal construction type: piers, platforms, racks and other facilities, and offshore oil and gas platforms and natural outcrops. On supports host system actuators 8 (figure 3), which transmit rotation from the Converter to the consumer either directly or through flywheels 14 and transmission systems. It is clear that the energy converters are unstable time and speed characteristics. Therefore, they can be loaded on machines and mechanisms directly, if they have the same parameters. For example, pumps, excavators, etc. Using the same energy converters as a drive for slow speed ElektroG is neration with stable performance characteristics rotation requires the introduction in the system of Executive mechanisms of additional devices, the decisive speed and time problems, such as the flywheel 14. Flywheels 14 are not only energy storage rotation, given their consumer 34 during a stop of the power Converter, but also serve as a stabilizer speed consumer 34, smoothing racing speed parameters of the energy Converter.

For the energy of the surface wind currents and waves (thread) garland 9 energy converters can be radiating from the support 7 (Fig 3) with embedded systems actuators 8 (figure 3). Such support will call "active". The second ends of the power converters are mounted at point support 10 (Fig 3) or rafts 11 (3)supplied to the armature 35, where no actuator systems 8. Such support will be called "passive". Due to the variability of the direction and speed of drift currents not all energy converters will work effectively. However, the design features of the turbine 6, resulting in the dynamics of the asymmetry of the pressure on her sides and the one-way rotation regardless of the direction of flow, to guarantee a positive net result of energy efficiency in an extensive network of energy converters loaded through managed 15 (Fig.7-9) and overrunning 19 (Fig.7-9) of the coupling and the adder (differential) 28 7, 8) on one common shaft (Fig) system actuators 8 (Fig, 9).

System actuators placed on the fixed support 7, are connected with the energy converters in the water using devices made in the form of farms, omitted from the support 7 to the level where the inverter energy. In areas with varying levels of water use device with telescopic joints, allowing you to modify the length of the shaft 18, shown in figure 4. On the platform 12 (figure 4) in the engine room 13 (figure 4) is a system of actuators 8, consisting of the flywheel 14, interconnected through controlled clutch 15. Communication with the power Converter through a telescopic pole, the ends of which there are nodes with transmission 16, 17, which are interconnected by four telescopic shaft 18. Their number can be different depending on water level fluctuations. All shafts 18, except for the extreme, have a clutch that allows you to telescopically connected to each other. Extreme shafts 18 are connected on the one hand with the flywheel 14 through the host system gear 17 driven 15 and overrunning clutch 19, and on the other with the power Converter, through the host system gear 16 driven clutch 15 and the cross connection 21. The hydraulic system 20, zadeystvuya telescopic pole, uses ene is the tech of rotation or of the flywheel 14, or Converter if appropriate connections controlled clutches 15. On the second end of the energy Converter must be similar to that of the telescope, operating synchronously with the first and going to system actuators 8, if the support is "active", or mud on the hydraulic system 20 on "passive" support. Driving clutch 15 of the hydraulic system 20 at both ends of the power Converter, continuously or discretely carry out lifting and lowering of the entire garland 9 energy converters, tracking water level.

Using the same device with telescopic connections are joining actuators 8 with the deep energy converters. They needed to put energy converters to the desired depth and rise to the surface in order to prevent, repair and replacement of turbines 1 or all garlands 9. In areas with constant water level connection of the inverter energy system actuators 8 through the device, made in the form of farms, omitted from the support 7 to the Converter, the ends of which are placed in the nodes of the transmission systems 16, 17 connected by a shaft 18.

Along with a stationary system with actuator systems 8, placed on a fixed support 7, the real possibility of existence have mobile hydrogen the economic device, built on the same principle as stationary. They differ from the stationary system is that instead of a fixed stationary support 7 and the peripheral point of the supports 10 is Royal craft 22 (figure 5, 6) with rafts 11 around him, anchored, 23. The energy converters 6, placed around the uterine vessels 22 radiating from it (threads) garlands 9, connected with the Board through Autonomous shafts, filling each to their system actuators 8 and are output to the adder 28 (differential), and then to the General system of actuators 8. 7-9 shows the construction schemes actuators 8. On one level the craft is compartment 26 (7) with four units 27 (maybe more) and the adder 28. Each unit 27 has a flywheel 14, connected to the water turbine 6 and the adder 28 through managed 15 and overrunning clutch 19. With adder 28 aggregate compartment rotation is transmitted on a common shaft with a Central flywheel 29 (Fig) and differential 28 next energy compartment 31. With differential associated complexes containing flywheels 14 (Fig.9) and loaded them low-speed (generators) consumers 34. Connection of the flywheel 14 by differential 28 and generators is h the rez managed 15 and overrunning clutch 19 and the gear system 32, 35 changing the gear ratio.

Royal craft 22 represents a huge float with the surface of the hemisphere (6) and underwater cylindrical stabilizer position 25. Inside the craft should be levels to accommodate all hardware and life support personnel. Royal craft 22 with the actuator systems 8 inside and garlands 9 energy converters with rafts 11 on Board outside it fixed travelling, you are at sea on a permanent or temporary (seasonal) anchorage. Garland 9 energy converters with rafts 11 are moved from the stowed position into the operating system begins to function.

The proposed system efficiently uses the energy of waves, and the energy of the water flow at any depth. This ability DGG technically achieved by using the water turbine with 6 blades 5, is made in the form of semi-cylinders, allowing not only to increase the effective area of the blades 5, but the number of blades 5, involved simultaneously in the power process. The number of blades 5 in the turbine 6 and the length of the arc of the blade 5 (diameter half) can be different. However, as can be seen from figure 2, they increase the distance between the blades 5 at the outer ends of the narrows (a'-' in figure 2). For turbines 6 with a small number of lop the stay 5 and a small speed these narrowing of the main interference will not create. The multi-blade and high-speed turbines 6 peripheral narrowing materially impede the free circulation of water. Therefore, the length of the arc of the blades 5 in this case, take such that the distance between outer ends of the blades 5 and the convex surfaces of adjacent blades 5 was the highest (a-b, figure 2).

The mobile system can be installed on all the seas and oceans of the Northern and southern hemispheres, from 20° latitudes and higher, where the influence of the Coriolis force. The most promising application of these system areas with frequent cyclones: the sea of Okhotsk, Japan, the Bering sea, Baltic sea, Barents sea, North and other sea.

Stationary system "Burial" advantageous to use in areas with the tides, and rivers, with a flow rate greater than 0.2 m/s essentially all of the Eastern and part of the Northern coasts of Russia are in the area of possible application of these DGG. It is safe to say that a stationary system will effectively operate on all the major rivers of the Far East, Siberia and Europe regardless of climatic conditions.

FIELD: hydraulic power engineering.

SUBSTANCE: proposed hydraulic turbine generators are designed for creating stationary and portable hydraulic plants of modular type. Generators have rotor with central shaft non-rotating around horizontal axis or vertical axis (as version) on which chain drive gears are rigidly fitted, each being coupled through independent chain drive with planet pinion members arranged radially and uniformly around central shaft. Each member has blade reduction gear consisting of gear of chain drive and of large and small cylindrical gears, the latter being coaxial and rigidly coupled with gear of chain drive of blade reduction gear, and large cylindrical gear is rigidly secured on axle of blade installed horizontally for generator (or vertically, as version). Each blade rests by ends of its axle for rotation on brackets secured on hubs by bases. Hubs are installed on both ends of shaft for rotation and tops of brackets at both ends of central shaft are connected by ring rims being drive wheels connected with energy converters by flexible drive.

EFFECT: provision of effective and reliable operation.
