The invention relates to hydraulic engineering, namely to Svobodnoye turbines, and can be used as a turbine generator-propulsion of the vehicle and turbine generator under conditions of slow flow of the working environment.

You know the Pelton Wheel (Ryzhkov C.V. 100 greatest inventions. M: Veche, 2005, s), containing a wheel rigidly connected with the horizontal shaft and vanes, arranged around him and feeding device of a strong water jet. The blades are made concave with a sharp edge in the middle of the cutting water jet.

The device was comfortable there, where there was the opportunity to create a strong water pressure. Under this condition, the efficiency was very high and close to 85%.

The disadvantage is the need for additional working conditions - high pressure water, requiring the device to a stable supply of water under pressure.

With strong water pressure increases cavitation, and slow water flow device is not effective.

Device energy working environment uses only partially, namely the rotation of the turbine itself is not producing current, which reduces the efficiency.

In addition, the device cannot be used as the propulsion of the vehicle, since the blade is not pushed, after leaving the working area, increasing energy losses in the SOP is otulana counter stream, what may cause them damage. This reduces efficiency and reduces operational capabilities.

Also known gravity active turbine on the application for invention No. 2006105932, F03B 1/00 adopted for the prototype and containing a horizontal shaft and are parallel to the axis of the shaft radial blades. Each blade contains multiple blade elements movably interconnected and the shaft by means of hinges with the possibility of unilateral deviations of the blades counter flow or copier in the direction opposite to the rotation of the turbine, and the return of the blade springs or copier in the deployed position before entering the working area. The shaft is rigidly connected to the blades and rotates with them.

However, the device uses the energy of the working environment only partially, namely the rotation of the turbine itself is not producing current, which reduces the efficiency.

The device cannot be used as the propulsion of the vehicle, because the blades will not zdvinutsya at operating speed (high) of the vehicle and the turbine, rotating towards the flow of the working environment, will create pressure on the blade outside of the working area, almost equal to the pressure on the blade in the working area, which will reduce the effectiveness of close to zero. This reduces operational capabilities.

The force of elasticity of the springs, zadvigaya blades after leaving the working area, bodų is less than the resistance of the working environment, and the blades will remain open, which will increase the resistance to rotation of the turbine, reducing efficiency, and create a counter rotation of the propulsion parasitic turbulent flow.

To apply copier, zadvigaya blades after leaving the working area, you need a powerful device, overcoming the resistance of the working environment, which can only be installed outside the turbine, which increases its size and clutter vehicle, limited in space, or other space. This copier provides a large number of moving mechanical linkages and assemblies requiring lubrication and complicating the design, which reduces the reliability and complicates maintenance.

Even the traditional use of the turbine, rotating the fluid flow, springs, control blades, with time stretch and may not securely hold them, for example, in the closed position after exiting the work area. This increases the flow resistance, the working environment, reducing efficiency. Using the elastic force of the springs together with the force of its own weight of the blades to sadhane the latter is only possible at low angular velocity of the turbine.

The task of the utility model is to increase the efficiency and enhanced operational capabilities.

Active hydraulic turbine includes a rotor with a horizontal shaft and vidvigalsya is using spring blades, located around it, and the device zadvigaya blades after exiting the work area.

Unlike the prototype it has installed in the blades by electromagnetic latches and piezoelectric elements, a device for transmission generated by the blades of the current, and the device, zadvigaya blades after leaving the working area, includes an electromagnetic element mounted to the stationary shaft interoperable after leaving the working area with spring-loaded electromagnetic latches, springs which are installed in the rotor with the opportunity to interact with the blades while the rotor is freely mounted on a fixed shaft rotatably around him.

The electromagnets of the electromagnetic latches are installed with the possibility of rotation.

The supply of each blade of the piezoelectric element provides current production blades. Each blade is a current generator, which allows maximum use of the energy of the working environment, increases the efficiency. This allows you to use the device as a turbine and turbine generator-propulsion of the vehicle that extends the performance capabilities. At the same time as working environment, you can use water, air, and partial immersion in water. The turbine generator can be used as a traction wines is and air vehicles.

A device for transmission generated by the blades of the current allows you to bring it to the consumer.

The presence of the fixed shaft is installed on the rotor with the possibility of free rotation, allows you to secure rigidly on the shaft stationary electromagnetic device element, zadvigaya blades after leaving the working area, thus increasing the reliability of the design.

The presence of the fixed shaft allows it channels for leading the cooling medium inside the hollow rotor and the output from the other end of the shaft is heated cooler. This allows you to use as a working environment recyclable hot steam and gas that was previously released into the atmosphere that extends the capabilities of the device.

Electromagnetic device, zadvigaya blades after leaving the working area, allows you to securely close the blades and hold in this position after the exit from the work area, even under extreme pressure working environment, working towards the rotation of the turbine, if used as the propulsion of the vehicle. Thus the resistance of the working environment is minimal after leaving the working area, which increases the speed of the vehicle. Part of the power produced by the blades, used for electromagnetic devices that Udo is but also economically.

The presence of spring-loaded electromagnetic latches, springs which are installed in the rotor with the opportunity to interact with the blades, ensure the operability of the turbine.

Installation of electromagnets in the latches to rotate allows you to rotate the magnets opposite the magnetic flux of the electromagnetic element. This speeds up the response of the electromagnets in the latches, increasing the speed of closing the blades after leaving the working area, and also reduces the current in the winding of the electromagnetic latches, due to the use of the magnetic flux with the shortest magnetic lines of force.

Hydraulic turbine comprises a sealed hollow rotor 1 mounted on a fixed horizontal shaft 2 rotatably around him. On the rotor 1 radially around the circumference of the fixed slide out lopas and 3 by means of hinges 4, figure 1-5. Each blade 3 comprises a base 5, for example, forged titanium, on which layers of densely laid: asbestos gasket 6, the inner electrocontact 7, the piezoelectric element 8, the external electrocontact 9, asbestos gasket 10 and mobile (bend under the pressure of working medium) membrane 11, for example of beryllium bronze, which presses the above-mentioned layers to the base 5 by screws 12. The tightness of the blade 3 provides a sealing gasket 13, for example, from aluminum, 7, 8. Electrical contacts 7 and 9 made, for example, electrolytic copper or beryllium bronze and connected to a flexible two-conductor of the electric wire, not shown.

The rotor 1 is freely mounted on the shaft 2 by means of two sleeves 14 and 15. Device for transmitting the generated current is performed, for example, in the form of headers (insert) 16 and 17, mounted respectively on the bushings 14 and 15, and the brush pairs 18 and 19 in contact with the collectors, respectively, 16, 17, 1, 2, 5. To the piezoelectric elements 8 are attached wires (not shown)located inside of the blades 3 to the shaft 2 and further connected to the collector plates 16, 17.

Brush pair 18 and 19 are held in the brush holders, respectively 20 and 21, secured to the levers 22 and 23, figure 5-6.

The torque from the rotor 1 through the gear 24 is transmitted to the generator is (not shown) in the case of the turbine as the turbine generator. In the case of the turbine as propeller-turbine generator for a vehicle torque from one or two motors (not shown) to the rotor 1 is transmitted through gears 24.

The device zadvigaya blades after leaving the working area comprises an electromagnetic element 25 mounted on the shaft 2 with the possibility of interaction after leaving the working area with spring-loaded electromagnetic latches 26 installed in the blade 3, the spring 27 which is installed in the rotor 1 with the opportunity to interact with the blades 3. Electromagnetic latch 26, rotated angle of 55°. Each blade 3 contains two springs 27, working in compression (without loading the spring 27 is stretched). The spring 27 on the one hand rests on the blade, and on the other hand, the stopper 28, figs 3, 4, 6, 7. Electromagnetic element 25 is made in the form of a semicircle and is rigidly fixed in the middle part of the fixed shaft 2, Fig 3, 9, 10. The spring 27 is set so that in the free state provides the opening of the blade 3 at approximately 5°.

In figure 1 the dotted line 29 shows the outer wall of the water or air vehicle, or hydroelectric facilities, and the dotted line 30 shows the level of the working environment.

Each electromagnetic latch 26 has two springs 31 and a channel for the wires, lead Pete is the electromagnetic latches 26.

All Elektrougli devices are connected in a common electrical circuit (not shown).

When used as a medium hot steam and gas cooling device serves the cooling fluid through the channels made in the shaft (not shown).

The device operates in two modes: turbo-generator-propulsion for the vehicle and turbine generator.

During operation of the turbine as the turbine generator-propulsion, for example, for a water vehicle, the turbine shaft fitted perpendicular to the direction of movement of the vehicle. The rotor is leading in relation to the working environment.

One or two of the engine (not shown) to transmit the rotation of the rotor 1, which overlaps the blades of the water moves the vehicle, performing the function of the paddle wheel. At the exit of the blade 3 from the working area of its electromagnetic latch 26, interacting with the magnetic field of the fixed magnetic element 25, are attracted to it and pushed. With the direct approach of the blade 3 to the electromagnetic element 25 of the magnetic field is amplified by summing the lines of force of the electromagnets latch element 26 and 25. The blade 3 is fully pressed against the rotor 1 (slid), overcoming the effect of the springs 27 and the working environment in the zone of high electromagnetic element 25, Phi is .3. As you progress through the upper semicircle (electromagnetic element 25) blade 3 strength of the interaction of magnetic fields of the latches 26 and the electromagnetic element 25 is gradually waning. 3 blade starts to move by the power of the influence of the spring 27, the water pressure and its own weight first 5-10°, the maximum appearing at the bottom point of 90°. When the interaction of the magnetic fields of the latch 26 and the element 25, the solenoid latch 26 is rotated counter magnetic flux of the electromagnetic element 25, increasing the speed of the closing blade 3. At the exit of the blade 3 from the zone of interaction of magnetic fields, the spring 31 will return the latch electromagnet 26 to its original position.

During the rotation of the blades 3 under the action of the working environment periodically SAG of the membrane 11, acting on the piezoelectric elements 8, which produce electric current. Next, the electric current through the wires through the collectors 16 and 17 is transmitted to the brush pairs, respectively, 18 and 19 and through them to the consumer or converted if necessary in the current of a different quality.

The operation of the turbine as the turbine is similar, but the rotor 1 is driven in relation to the working environment, and rotates in the direction of its motion.
