The invention relates to the field of energy and is designed to convert the energy flows of the rivers, tides into electrical energy AC or DC.

Known floating power plant containing a craft with the installed generator connected to the turbine (see US patent No. 1631647, CL F03 17/00, 07.06.1927).

However, this floating power plant has a low efficiency because of low efficiency, low energy water stream in which you installed turbine.

Closest to the invention is a floating plant that contains the craft with the installed generator connected to the turbine, and an in-stream water tapering in the direction of water flow confused pipeline (see patent RU No. 2049924, CL F03 17/06, 10.12.1995).

However, this floating power plant has a relatively low efficiency, which is due to the fact that the slow rotation of the impeller turbines requires the use of heavy and expensive multipliers for transmitting rotation to the generator. In addition, there is a delay in the response of the turbine to change the currents associated with a large move at the moment of the impeller, preventing rotation of its axis of rotation due to gyroscopic forces. This leads to a significant loss Virab the TCI electricity and power turbine.

Task to be solved by the present invention is directed, is to simplify the design of floating plants, improving its performance and increasing the efficiency of energy use of water flow.

The technical result achieved from the implementation of the invention is to increase the efficiency and reliability of the plant.

This problem is solved and the technical result is achieved due to the fact that the floating air power contains the craft with the installed generator connected to the turbine, and an in-stream water tapering in the direction of water flow confused pipeline, this confused the pipeline is installed horizontally and its smaller end provided with a horizontally placed diffuser pipe with an orifice at the entrance to the latter, and in the neck of the diffuser pipe coaxially installed air nozzle, coupled with the side of the entrance with a curved ending in a vertical pipeline, duct, connected by a hinge with a confused air pipeline, in which on the output stage of installed turbine, and the air duct is connected with the hinge can be rotated relative to the air confused pipeline and installation confused pipe with diffuser pipe for water flow.

Preferably the area of the cross output section of the nozzle is 25-30% of the sectional area of the throat of the diffuser pipe.

Preferably located in the confused water pipeline from the entrance is equipped with a grill made of rods with a streamlined cross-section.

The air nozzle may be installed along the axis of the neck, and in the last round nozzle installed curved twisting along a helical line along the diffuser pipe the water flow of the scapula.

The air nozzle can be made circular and is installed along the wall of the neck forming the walls of the air nozzle axial liquid nozzle for supplying water from confused pipeline along the axis of the diffuser pipe, a liquid nozzle mounted longitudinal curved in a spiral plate for a spin flow of water along a helical line along the diffuser pipe.

The research found that the most expedient to use the energy of water flow for the organization of high-speed air flow, which establish a turbine driven by the last generator. This provides several advantages.

Water is a design that has no moving parts, which reduces to operate the operating expenses.

Turbine installed in high-speed air stream that moves away from material-intensive, expensive and structurally complex multipliers for transmitting rotation from the turbine to the generator.

Install all components with moving parts and connections above the water level on the craft, facilitates maintenance and repair of structural elements of the plant.

Figure 2 schematically presents a floating water plant with the annular air nozzle located along the wall of the neck of the diffuser pipe

Floating water-and-power plant comprises a vehicle 1 with the installed generator 2 connected to the turbine 3, and mounted in water flow tapering in the direction of water flow confused pipeline 4. The latter is installed horizontally and its smaller end provided with a horizontally placed diffuser pipe 5 neck 6 at the entrance to the last. In the neck 6 of the diffuser pipe 5 coaxially installed air nozzle 7, the United side entrance with a curved movable in vertical pipelines the 8 air duct 9, United by a hinge 10 with a confused air pipe 11, in which the output stage of installed turbine 3. Vertical piping duct 9 is connected to the hinge 10 can be rotated relative to the air confused pipeline 11 and installing confused pipe 4 together with the diffuser pipe 5, with which it is connected through an air nozzle 7 is installed in the neck 6, along the water stream.

The area of the cross output section of the air nozzle 7 is 25-30% of the sectional area of the neck 6 of the diffuser pipe 5.

Located in the confused water pipeline 4 on the input side it is equipped with a grating 12, is made of rods with a streamlined cross-section.

The air nozzle 7 is installed along the axis of the neck 6, and the last around the air nozzle 7 has a curved twisting along a helical line along the diffuser pipe 5 water flow vanes 13.

The air nozzle 7 is made of a ring and is installed along the wall of the neck 6 with the formation of the walls of the air nozzle 7 axial liquid nozzle 14 for supplying water from confused pipe 4 along the axis of the diffuser pipe 5, while the liquid nozzle 14 mounted longitudinal curved in a spiral plate 15 for a spin flow of water through the screw if the AI along the diffuser pipe 5.

When placing a floating water plant in water flow, for example on the river, under the action of water flow confused pipe 4 together with the diffuser pipe 5 is located along the flow of water, while water through the grate 12 enters confused pipeline 4 and by narrowing the last accelerates. High-speed water flows into the neck 6 of the diffuser pipe 5 and, flowing the air nozzle 7, it creates a vacuum which causes the entering air nozzle 7 through the duct 9 from the surrounding craft 1 of air through the air confused pipe 11 of the air. Acting in a confused air pipe, the air is accelerated with the formation at its output a narrow area of high-speed air stream, which runs onto the turbine 3, and forcing them to rotate its impeller that rotates connected to the turbine rotor of the electric generator 2 and the last generation of electrical energy.

At the location of the floating water plants in the flow with low velocities of water it is advisable to install in the neck 6 tools for a spin flow of water, which helps to increase the flow velocity of water at outlet section of the air nozzle 7 when the flow past the flow of water and consequently additionally enhance which is created by the flow of water Ratri is the air nozzle 7.

Furthermore, additional opportunities to reduce labor costs for operation of the plant is achieved due to the fact that during normal operation of power provided a stable position along the water stream forming flow part for water confused and diffuser pipes 4 and 5. At the same time, when the clogging of the grate 12 waste water ceases to flow into confused pipeline 4, which causes an uneven flow water flow confused and diffuser pipes 4 and 5. The result is lost sustainable longitudinal location along the flow of water confused and diffuser pipes, and they turn on the duct 9 across the flow of water, which causes an automatic reset of the garbage and rinse the grates 12 water stream, after which the same water flow confused and diffuser pipes 4 and 5 are rotated (like a weather vane in the wind) and installed in its original position along the water flow, and operation of power is resumed.

This invention can be used wherever there is natural flow of water, particularly on rivers and in coastal areas of seas and oceans, where during low tides and high tides creates a flow of water.
