The invention relates to the field of electrical engineering and can be used to convert the energy of the current environment in electric, for example, in a hydroelectric dam.

Known engine for utilization of the energy of the current environment (EN 2166664 C1, F03B 9/00, 2000), which does not require dams and implements energy at low flow velocities through the use of oncoming traffic of different blades. Due to the fact that the blades are moving on the rollers in the grooves of the flexible guides with each rotation on its own axis, the device has a significant disadvantage in that its design does not allow for the required power and has a limited service life.

Known engine for energy recovery current environment containing two turbocodes representing mutual mirroring (EN 90131 U8, F01D 15/00, 2009). The device allows to obtain higher power and has sufficient service life. However, when used in turbo-expander set its design requires two opposing streams of the current environment that hydroelectric dam is not realizable. In addition, to obtain the required output power at low velocities of flow of the current environment (which is typical for dam power plants) the presence of two turboc the forest is not enough.

Closest to the invention is an engine for energy recovery current environment containing immersed in the latest frame and the housing and rigidly associated outer space having at least three turbocodes installed on a single longitudinal axis directed along the flow, the main and auxiliary PTO shafts connected by gears, and turbocodes installed with the possibility of synchronous rotation and the longitudinal axis fixed to the frame through the bearing assemblies and the first and third turbocodes mounted on an axis rigidly and through a chain transmission connected with the main shaft of the power take-off (US 1396609 A, F03B 17/06, 1921).

In the known device all turbocodes secured to the longitudinal axis rigidly, but their blades are oriented in the same direction, so the flow rate through the engine and, consequently, its capacity is limited, since it is determined only by the speed of rotation of turbocodes (speed external thread), not depending on design features of the system.

The technical result that can be achieved with the implementation of the invention is to increase the power output of the engine.

The technical result is achieved by the fact that in the drive for energy recovery current environment containing immersed in the latest frame and the body ill is related to outer space, having at least three turbocodes installed on a single, directed along the longitudinal flow axis, the main and auxiliary PTO shafts, which are interconnected identical gears, and turbocodes installed with the possibility of synchronous rotation and the longitudinal axis attached to the frame via bearing assemblies, with the first and third turbocodes mounted on an axis rigidly, through a chain transmission connected with the main shaft PTO, according to the invention, the second turbocodes fixed on the longitudinal axis through additional bearing unit, is connected with the auxiliary PTO shaft through a chain transmission, while the neighboring turbocodes representing mutual mirroring, kinematically connected so that they rotate counter-synchronously.

When performing engine with five TurboCache first, third and fifth in the direction of flow of turbocodes secured to the longitudinal axis rigidly, and the second and fourth through bearing assemblies.

In figures 1, 2, 3 presents the design of the device using three turbocodes.

Figure 1 shows a General view of the structure.

Figure 2 - left side view.

Figure 3 - top view.

The figure 4 presents the design of the device when using five turbocodes.

The device (1, 2, 3, 4) contains the Arkas 1, rigidly fixed in the stream, building 2, made in the form of a pipe with open areas, and strictly related to outer space 3. The longitudinal axis 4 is fixed to the frame by means of bearing assemblies 5. The first turbocodes 6 rigidly mounted on the axle 4, the second turbocodes 7 is connected to it through the bearing unit, and the third turbocodes 8 is also fixed on the axis. Turbocodes associated with 9 main and auxiliary 10 PTO shafts through chain transfer 11. The shafts 9 and 10 are connected through gears synchronization 12. The main shaft 9 is connected to the generator 13. When using five turbocodes (Figure 4) on the axis 4 are installed 14 fourth and fifth 15 turbocodes.

The device operates as follows.

The flow of the current environment, for example, water, acts on the blades of turbocodes 6, 7, 8 (in the variant with three TurboCache).

Because turbocodes 6 and 8 are identical and are rigidly connected to the axle 4, which is fastened on the frame 1 on the bearing assemblies 5, turbocodes 6 and 8 start to rotate under the influence of a stream. Attached to the axis 4 through the bearing unit turbocodes 7, which is the mirroring of turbocodes 6 and 8 starts to rotate towards them. The rotational motion of turbocodes 7 through a chain transmission 11 is transmitted to the auxiliary shaft 10 PTO, and the rotational motion is of turbocodes 6 and 8 is transmitted to the main shaft 9 PTO, connected to the generator 13.

Since the shafts 9 and 10 are connected through identical gear 12 (Fig 3), all turbocodes rotate synchronously, while neighboring turbocodes rotate counter due execution of their designs reflector. Blades adjacent (6-7 and 7-8) turbocodes move the zone of the current environment: some people with high blood pressure, low blood pressure. When meeting these areas, moving towards each other, the flow from areas of high pressure rushes into the area of low pressure with the formation of vortices.

Since the movement of the blades of all turbocodes synchronized, this process is not stochastic, and orderly. As a result, the flow rate through the engine is increased, and, consequently, increases its power.

A further increase in capacity of the installation is possible by increasing the number of turbocodes, for example, up to five (Figure 4). In this case, the first 6, the third 8 and 15 (all odd in the direction of flow) turbocodes fixed on an axis rigidly, and the second 7 and the fourth 14 (all even in the direction of flow) through bearing assemblies. Each turbocodes kinematically connected with the main and auxiliary PTO shafts in accordance with their rooms.

Operation of the engine with five or more TurboCache similar to the operation of the engine with three what orbecause, but provides even greater speed through the engine flow and the speed of rotation of the main shaft, resulting in an increase transmitted to the electric generator 13 power, and it is implemented without significantly increasing the complexity of the installation and, therefore, its value.

Thus, due to the installation of turbocodes even-numbered with the possibility of rotation on the longitudinal axis and perform design neighboring turbocodes mirroring ensures the constancy of the direction of rotation of the main shaft associated with the generator, and also increases the speed of flow through the engine, thereby increasing power output of the unit, i.e. the achievement of a technical result.

It is established that the application of three turbocodes the plant capacity increases by more than 50%, while the price of hydroelectric power only increases by 20-30%, and in the application of the five turbocodes power increases more than twice the price of the installation increases by about 50%.

Due to the high given power at a relatively low cost of the installation of the invention may be recommended when designing a dam hydroelectric power plants.
