The invention relates to a hydraulic power installation for generating electrical energy by converting energy of water flow through a centrifugal machine, containing at least one rotor driven by the rotor of the generator and the float for centrifugal machines, and vane machine still of Sankaran, and the rotor is oriented in the direction of flow of water. In the framework of the invention, the term "rotor" includes impeller and the impeller, as well as propellers, etc. as the flowing waters there are sea currents and rivers.

Otherwise than in wind power plants, which convert the flow energy of wind into electrical and have at calm have to put up with the downtime, hydropower plants can continuously generate electrical energy, since current water are in constant motion. Known hydropower installation described above forms of execution that contains floating on the surface of the water blade car. This is unsatisfactory, on the one hand, in aesthetic terms, as it violates the landscape, and on the other hand, have to put up with reduced energy conversion, because the rotor is in the form of execution, usually in the form of a vane wheel partially immersed in the flowing water and is driven (DE 4112730 C2). Known, however, as the vane machines for use in underwater hydroelectric plants, in which the impeller is located on the frame, and the frame is installed on the Foundation on the bottom of the reservoir. A similar form of Foundation work is difficult, and sufficient anchoring of the frame on the Foundation of almost not ensured, so that a sufficient orientation paddle wheels in the direction of flow is almost not provided (DE 20011874 U1). Another underwater vane machines to generate the energy axis of the rotor mounted on the lower end with a trunnion rotatably in the bearing. This bearing is located in the compound Foundation, portions of which have to deliver swim to the destination and collect there by divers at the bottom of the reservoir (DE 29900124 U1).

The basis of the invention lies in the task of creating a hydropower installation described above forms of execution, vane machine which during operation is not visible, allows the installation in a short time and, in addition, is characterized by simple design in relation to equipment installation and maintenance.

This problem is solved according to the invention, the generic hydropower installation due to the fact that centrifugal machine is held under the surface of the water in suspension and that the float is made with possibility of a choice of blowing a gaseous medium, for example compressed air and, if necessary, fill with water.

<> These measures have the effect that vane machine during operation is not visible and, therefore, meets the aesthetic attitude all the requirements, because the landscape is saved. In addition, the rotor throughout its periphery is constantly in the flowing water, and, consequently, an optimum conversion of the energy currents into electrical energy. Next can be implemented relatively simple in construction design, which enables its application in a short time and easy Assembly. Also maintenance and repair to carry out relatively easy, since the centrifugal machine by loading a gaseous medium, for example by inflating the float compressed air, can be lifted to the water surface. In fact, the process of lifting and lowering can be controlled via air tube by air flow, if necessary, by filling it with water. It is also possible lowering of the centrifugal machines on the bottom of the reservoir.

Other significant for the invention of the signs below. Thus, the rotor is installed on oriented in the direction of the water flow axis, and its blades are made to rotate by means of the turning mechanism in the direction of flow or against it, for example, to prevent a decrease in power when exceeding a preset value napoletane. It manages the rotor blade due to the provisions of the option and, therefore, reduce surface leakage. Further, the invention provides that the axis of the rotor is made in the form of a hollow axis and forms a float. This hollow axle has a high Flexural rigidity and contributes to the orientation of the rotor in the direction of flow of water. According to the invention the blades are rigidly mounted on the axis of the rotor is made with the possibility of deviation in the direction of flow and by loading springs are held straight against the pressure of the flow and the excess pressure reaches the specified value deviate in the direction of flow with reduction of surface leakage. This provides a relatively simple and functional mechanism of rotation of the rotor blades. This applies in particular when the rotor blades on its facing the current side are guided by the abutment noses on the decompressed spring blades, distributed on the periphery of the rotor axis and fixed on her. The force of these springs blades determines the pressure of the flow in which the rotor blades are held straight. Only if the pressure of the flow exceeds the force of the spring blades, the rotor blades will be deflected as if in the position of the checkbox.

According to another variant embodiment of the invention the axis of the rotor is of the arrester, prices rotor blades articulated guides levers, and the guide levers coupled with a support ring mounted for movement on the axis of the rotor in its longitudinal direction, and further between the counter and the support ring is located around the axis of the rotor, the compression spring in the form of a spiral spring which loads the rotor blades through the guide levers and against the direction of water flow. In this case, the rotor blades are rejected, if the effective pressure of the flow exceeds the spring force of compression. The axis of the rotor may be made, at least on the front and rear ends to form the spindle axis, with the arrester and/or bearing for the rotor blades made in the form of floating on the spindle axis and fixed uterine nuts to tighten the compression spring by a specified amount or to vary the spring force. According to one vidoesseanna variant embodiment of the invention between the support ring and the support for the rotor blade is located surrounding the spindle axis, a spiral compression spring or tension, and the support ring and the bearing for the rotor blades made in the form of uterine nuts. In this case, the direction of flow and, therefore, loading of the rotor blade from a particular direction depends on whether located between the support ring and the support for the rotor blade spring to work as p. the dinners compression or tension.

Further, according to the invention, the axis of the rotor with a predetermined interval there are several rotors with pivot mechanism each. This variant embodiment of the invention the pressure of the water flow is distributed across multiple blades of the rotors, so that even small velocity provide enough energy conversion. At the same time reduces the pressure of the flow due to its distribution on individual blades of the rotor. This holds, in particular, when the outer diameters of the rotors or blades grow in the direction of flow of water to a predetermined level and exceed the outer diameters respectively of the previous rotors.

Mostly the axis of the rotor is made in the form of a hollow axis of the conically widening in the direction of flow of water, and differs due not only favorable in relation to the current design, but reduces at the same time affecting preplechovany the load generator and, in particular, bending efforts. The hollow axle is suitable of forming a hollow chamber sections with each rotor and made with the possibility of extension, and cuts the axis is configured to attach to each other through a gas - or air - and watertight flanged connections. Due to this, the axis of the rotor can be selectively lengthened with a sufficient stability of the buoyancy. In this regard, it is also possible to maintain the rotor axis with predetermined intervals through the guide supports. Further back towards the downstream end of the rotor axis may include a guiding device, which provides the perfect orientation axis and the rotors.

The generator can be placed in a waterproof housing, for example housing of the hemispheres, such as half pipes, with cooling ribs on the outer side, which are predominantly in the longitudinal direction of the casing and, consequently, in the direction of flow. Then there is the possibility of the placement of several generators in a row one behind the other and attach them to each other and to the axis of the rotor for optimum energy conversion into electric current. For hydraulic reasons, the body-side leakage can be prepracovan hollow cone flow, which is also in the field of the generator takes care of the lifting force, as the float is formed mainly by the hollow axle, if necessary, the casing and the cone wrap. According to another variant of the invention, the float is formed of a frame by frame with hollow beams and/or boxes for one or more vane machines. In addition, to fill the float may be attached one or more gas - Il is pnevmoprivod. Finally, the invention provides that several bladed machines are located in a row near one another and/or offset each other and attached to each other if necessary, the flexible or elastic connecting means to implement something like a power plant. Centrifugal machine or machine sankarani on the shore or on the bottom of the reservoir chains, cables, etc. so that in the latter case, the anchoring is imperceptible.
