Wave-flow power installation

FIELD: machine building.

SUBSTANCE: present invention pertains to hydraulic power development. A support arm with a hinge, enabling rotation and fixing the water pipeline in the direction of flow of water, allows for using the power installation as a flow power installation or as a wave power installation. Functional capabilities of the power installation are widened due to use of water pipelines with orthogonal turbines and an electric power generator under water on the support arm. The amount of electrical power generated can also be increased due to that, the blades are oriented in opposite directions for rotation of orthogonal turbines in opposite, unchanged directions, independent of the direction of flow through the orthogonal turbines. The inductor coil of the electric power generator is immoveable, has two-directional operation and is between neighbouring short-circuited rotors, each connected to its axle of the orthogonal turbine. The short-circuited rotors rotate in opposite directions, are fitted with small clearances from the inductor coil and are fixed using lining made from material with low sliding friction. As a result, there is increased efficiency of using energy of water passing through the flow part of the convergent-divergent water pipeline.

EFFECT: wider functional capabilities of a power installation with orthogonal turbines.

The invention relates to the field of hydropower construction and can be used in the construction of low-pressure river or wave energy installations.

Known turbine installation comprising two horizontally coaxially installed in the conduit of the turbine and one generator (see ed. testimony SU # 1280178, CL F03B 13/10, 30.12.1986).

In this power plant turbine shafts coaxially oriented along the conduit and connected to the multiplier, placed in a sealed capsule in the center of the conduit with a vertical shaft generator installed outside of conduit. However, this leads to a low efficiency of energy use of the water flow passing through the cross section of the conduit. This is because the turbine, in this case a propeller type are alternately depending on the flow direction, and the fact that the capsule of the multiplier is placed in the center of the working section of the conduit, partially overlaps directed along the shaft turbines worker thread.

Closest to the invention to the technical essence and the achieved result is an energy installation comprising two orthogonal turbine with blades hydrodynamic profile, horizontally coaxially installed in confused-diffuser conduit, and an electric generator, while the turbine you Olney orthogonal cross-flow, their shafts are oriented transversely of the conduit installation and one of the ends of the shafts of each of the orthogonal turbine is fixed in the wall of the conduit, the generator is located between the orthogonal turbines, kinematically connected with the shafts orthogonal turbines and placed in a sealed cavity (see patent RU No. 2216644, CL F03B 13/00, 20.11.2003).

However, the design of this power plant is an essentially stationary power plant, which can swim to deliver to the place of its use and install on the bottom of the reservoir, for example in the coastal zone of seas and oceans or on the bottom of the river, which narrows the possibilities of its use, and the generator through the shaft connecting the shafts orthogonal turbines, it is not possible to more fully utilize the energy of water flow to generate electricity.

Task to be solved by the present invention is directed, is to expand the functionality of the use of energy installation.

The technical result is achieved by improving the efficiency of energy use of the water environment, through the flow-through part confused-diffuser conduit.

This problem is solved and the technical result is achieved due to the fact that Volno-flow energy condition is the time contains two turbines with blades hydrodynamic profile horizontally coaxially installed in confused-diffuser conduit, and an electric generator, while the turbines are made orthogonal, their shafts are oriented transversely of the conduit installation and one of the ends of the shafts of each of the orthogonal turbine can be mounted in the wall of the conduit, the generator is located between the orthogonal turbines, kinematically connected with the shafts orthogonal turbines and placed in the cavity, while the plant is equipped with a float, a conduit installed beneath the float bracket with hinge can be rotated conduit for orientation axes orthogonal turbines perpendicular to the flow, the blades of one of the orthogonal turbine is oriented in the opposite direction relative to the blades of the second orthogonal turbines for rotation orthogonal turbines in the opposite, constant direction regardless of the direction of current flow through the orthogonal turbine, the inductor generator is stationary double-acting and is located between the United each with its shaft orthogonal turbine rotors (for example, short-circuited), rotating in opposite directions and mounted with a small clearance relative to the inductor, fixed strips of material with a low sliding friction.

In the course of studies the study identified the possibility of extending the functionality of generators of orthogonal turbines due to the installation of conduit orthogonal turbines and generator under water on the bracket, attached to the float. This releases any restrictions on the topography at the location of the power plant and there is no need for the bottom in the place of installation of the power plant and the bracket with hinge, allowing you to rotate and fix the conduit in a flow direction of the water flow, allows you to use the power as a flow energy installation or as a wave power plant. Additional opportunities to increase the generation of electric energy by the electric generator is achieved due to the fact that the blades are oriented in opposite directions to rotate the orthogonal turbines in the opposite, constant direction regardless of the direction of flow through the orthogonal turbine, induction generator is stationary, double-acting and is located between the United each with its shaft orthogonal turbine squirrel-cage rotors rotating in opposite directions and mounted with a small clearance relative to the inductor, fixed strips of material with a low sliding friction.

Figure 1 schematically shows a longitudinal section Volno-flow energy installation with vertically installed conduit.

figure 2 schematically shows a longitudinal section Volno-flow energy installation with a horizontally mounted conduit.

Volno-flow energy installation contains two turbines 1 and 2 with blades hydrodynamic profile, horizontally coaxially installed in confused-diffuser conduit 3 and the generator 4. Turbines 1 and 2 are made orthogonal, their shafts 5 and 6 are oriented transversely of the conduit 3 installation and one of the ends of the shafts 5 and 6 each orthogonal turbines 1 and 2 are fixed in the wall of the conduit 3. The generator 4 is located between the orthogonal turbines 1 and 2, kinematically connected with the shafts 5 and 6 orthogonal turbines 1 and 2 and is placed in the cavity 7 formed by the casing 8 and the cavity 7 with the need to ensure high reliability can be made airtight (in normal conditions sealed cavity 7 and the housing 8 to use it is not necessary). The plant is equipped with a float 9. The conduit 3 is installed under the float 9 on the bracket 10, provided with a hinge 11 can be rotated conduit for orientation axes orthogonal turbines 1 and 2 perpendicular to the flow. The blades of one of the orthogonal turbine 1 is oriented in the opposite direction relative to the blades of the second orthogonal turbine 2 for rotation orthogonal turbines 1 and 2 in the opposite, constant direction regardless of the direction of current flow, such as flow of water in the river, through orthogonal turbines 1 and 2. The inductor 12 electrode is erator 4 is stationary, double-acting and is located between the United each with its shaft 5, and 6 orthogonal turbine, respectively, 1 and 2, the rotors 13 and 14, rotating in opposite directions and mounted with a small clearance relative to bilateral inductor 12, fixed spacers (not shown) of a material with a low sliding friction. Through the bracket 10 from the generator 4 skipped electric cable 15.

Volno-flow energy installation operates as follows.

When using Volno-flow energy installation as wave power plant the conduit 3 is installed vertically (see figure 1). If you move the installation together with the wave up and down through the conduit creates a flow of water surrounding the conduit 3, which causes the rotation orthogonal turbines 1 and 2. This rotation is transmitted to the shafts 5 and 6 and from the latter to the rotors 13 and 14. The rotation of the rotors 13 and 14 relative to bilateral inductor 12 and the electric generator 4 generates electric power, which the cable 15 is transmitted from the generator 4 to the consumer.

In the case of Volno-flow energy installation as a flow energy installation using a hinge 11 to the conduit 3 set horizontally (see figure 2). Volno-line installation octanal who live, for example, on the river, and the conduit 3 automatically, under the action of a stream is located along a river. Further work Volno-flow energy installation is the same as described above. The flow of water flowing through the conduit 3, causes the rotation of the turbines 1 and 2 and, accordingly, their rotors 13 and 14 relative to bilateral inductor 12 and generated by the generator 4, the electrical energy cable 15 is transmitted from the generator 4 to the consumer.

The present invention can be used to create environmentally friendly power plants on the rivers, in coastal areas and in places of accommodation platforms for underwater mining of minerals.
