The invention relates to small hydropower, and is intended for the energy of the fluid.Hydroelectric known, which contains a conduit located therein a turbine with horizontal shaft, equipped with ENU, interacting with the gear horizontal shaft turbines. The unit further comprises a second turbine located coaxially with the first and having a horizontal shaft with bevel gear interacting with a horizontal gear vertical shaft of the rotor. Vertical rotor shaft with the possibility of vertical movement and provided with a second bevel gear meshing with the left and right vertical bevel gears turn.The disadvantage of this unit is the complexity of its kinematic scheme and, consequently, reduced reliability.Also known wave power plant, which contains the float and its associated vertically positioned tubular casing is submerged beneath the water level and having a tapering inside the site hosting the capsule and the turbine is kinematically connected with the generator placed inside the capsule and having a rotor and a stator with windings. The impeller turbines, with each end provided with guide vanes, the rotor of the generator is fixed on the inner part of the impeller and provided with permanent magnets with axial, orie the military skoboobraznye shoes, the soles are installed opposite to the magnets of the rotor.The disadvantage of this setup is its complexity, weight and limited power.This setting is for the energy of the fluid can serve as a prototype and the base object for the device.The purpose of the invention is to simplify the design of the facility and increase its capacity.This objective is achieved in that the generator installation is made in the form of two pairs located in the horizontal plane and one within the other conical disc of the stator and rotor, and the two couples facing each other in large grounds, and between pairs is the turbine wheel drum while the outer conical surface of the disc rotor is equipped with a vertical turbine blades, and the outer conical surface of stator - slots with encapsulated winding in the form of segment groups, spaced evenly around the circumference, and the dish-shaped stators and wheel drum type represent a single unit and made with the possibility of rotation of the disc towards the rotors.In Fig. 1 shows the proposed installation, the longitudinal RAZR horizontal conical disc rotors 1, which is also the rotor of the generator. Inside of the rotors 1 are horizontal conical stators 2, which is simultaneously the stator of the generator. The rotor 1 and the stator 2 form two pairs, facing each other in large grounds. Between the pairs is the turbine wheel 3 drum type. The wheel 3 is rigidly connected with the stator 2.The conical outer surfaces of the rotor 1 is equipped with a vertical turbine blades 4, and the outer conical surface of the stator 2 is provided with grooves 5, which form a segment group, spaced evenly around the circumference. The number of segment groups any, but not less than two. The slots 5 of the stator 2 is filled encapsulated winding (not shown). In Fig. 2 shows a vertical blade 4 and the slots of the stator 5, only the top pair on the bottom everything is the same. Also shown conventionally only one segment of the group of grooves 5 of the upper pair.The rotor 1 and the stator 2, and rigidly connected with the stator wheel drum 3 is made to rotate towards each other. The installation is located on the cradle 6 is installed on the bottom and is fixed relative to the bottom with stretch marks 7 and anchors 8 and the unit C is sudestada using the cable 10.Does the installation for the energy of the fluid as follows.The whole setup is immersed in water and placed on the stand 6, which is fixed relative to the bottom with stretch marks 7 and anchors 8, and the system itself is fixed relative to the shore with the help of stretch marks 9. Water, its current impact on vertical turbine blades 4 mounted on the outer conical surfaces of the rotors 1 and vertical turbine blade drum wheel 3. Wheel 3 and is rigidly associated with the stators 2 start to rotate towards the rotation of the rotor 1. In the winding slots of the stator occurs electromotive force and thus obtained the power through the cable 10 is passed to the consumers.The proposed installation has significant advantages in comparison with the prototype and the base object. First, the installation does not have a generator, since it is itself the generator, and therefore has no gearbox and kinematic pairs for the torque transfer, which significantly simplifies the design and allows you to make it completely flooded, and this, in turn, can significantly reduce the load on the bearings due to the power Arhim is their rotors and stators, as well as the fact that the stator is located inside the rotor allows, in comparison with the axial rotors and stators to get the same diameter rotor for more torque, due to the fact that the rotor is not closed by the stator, and also receives the energy of flowing water, and the presence of the turbine wheel drum type allows the rotor 1 to rotate toward the stator 2, which at the same linear velocity increases the electric power of the unit at least twice, with all the ensuing economic effect.Since the rotors are not closed stators, this allows to reduce the size of the blade height on the conical surface of the rotor and due to this reduction to introduce additional wheel, providing vstrechnoi rotation. Thus, when the same length of working blades as the prototype for the proposed installation, you can get twice the power. (56) USSR Author's certificate N 1583649, CL F 03 B 13/12, publ. 1990.
