The disadvantages of the described devices are low power density and low efficiency of water use, due to the fact that the filling of the compartments of the water-wheel is not more than 60-70% of the volume, with part of the water discharged from the compartments during the rotation due to the presence of the gap between the surfaces of the wheel and the retention element, difficult to manufacture the design of the blades of the wheel and the need to use them in large quantities to increase the fill rate of the compartments of the water wheel.
Solved technical problem of the present invention is to increase the specific power of the device and the efficiency of water use, simplifying the design.
Solve the technical problem in the device for converting energy of water into mechanical energy of rotational motion containing water wheel of rigidly connected side walls, blades and hub, power and drainage systems, water-retaining element attached to the housing, is installed from the bottom to the top points of the side walls of the water-wheel from the side of the working part is made radially curved and of a width equal to the width of the water-wheel and water wheel through the hub and bearing assemblies mounted on the housing, is achieved in that the device comprises a second water to the forest, identical in construction with the first water wheel and is also equipped with the same water-retaining element, both water wheels are connected to each other kinematically by means of gears and mounted on the housing made in the form of two plates connected water-holding elements, symmetrically relative to the vertical axis of power systems on the distance of the radius of the water-wheel, the blades of each of the water-wheel is made in the form of plates of rectangular shape and is fixed to the hub and the side walls of the wheels so that between the inner surfaces of the hub, blades, side walls formed pockets, fully filled with water from the side of the working parts of the two water wheels hold water during the rotation to the lowest point.
The invention is illustrated by drawings, where figure 1 shows schematically the device for converting energy of water into mechanical energy of the rotational motion, the longitudinal section a-a, figure 2 - top view.
The device (figure 1, figure 2) contains two water wheels 1, exactly the same design of the rigidly connected to the hub 2, two side walls 3 in the form of a disk, flat blades 4 and kinematically connected gear 5 for their simultaneous rotation. The device also includes bearing assemblies 6 to the 7 STS, made in the form of two plates connected water-holding elements, power 8 and drainage (not shown) of the system. The device is equipped with a water-retaining elements 9, which are made radially curved and mounted rigidly on the part of the working parts of water wheels on the housing 7 without a clearance. The blades 4 of each of the water-wheel 1 is designed as a flat rectangular plate with length equal to the width of the wheel and rigidly connected with the hub 2, and ends with side walls 3. The number of blades is chosen with regard to the size of the water-wheel.
A device for converting energy of water into mechanical energy of the rotational motion is as follows. Water from the reservoir (not shown) for power system 8 is fed from above into the chamber water wheels 1 through the conduit of rectangular cross-section. The feedwater flow is controlled by the guiding apparatus is equipped with a drive (not shown). Next, the flow of water, keeping its original vertical movement interacts with the blades 4 water wheels 1, gives them the potential and kinetic energy, which is converted into mechanical energy in the form of rotational torque on the shaft. The movement of the entire mass flow of water in one, only in a vertical direction result is to improve the hydrodynamic characteristics of the flow, for example, to reduce energy loss, improve the uniformity and speed of flow. This allows you to increase bandwidth and power density of the device, greatly improve operational capabilities, for example, it can be used in a wide range of pressure stream of water. Increasing efficiency of water coming from the power system, the proposed device is achieved by establishing in the case of one of the second water wheel, exactly the same design, having a kinematic connection with the first water wheel and use the retention elements of elastic material, is rigidly fixed in the housing without a clearance and is pressed against the surface of the side drive water wheels. Increasing the power density of the device is ensured due to the torque increase due to full fill all compartments (pockets) of the working parts of the two water wheels and water retention in them without loss in rotation to the lowest point.
The volume of retained water depends on the geometric dimensions of water wheels and can be calculated by the formula: V=πR2H, where R is the radius of the lateral disks, H - the width of the water-wheel.
An additional technical effect of simplifying the structure of the device for converting energy of water into rotational energy e is to achieve is achieved by reducing the number of blades, designed as a simple plate of rectangular shape, convenient for attachment to the hub and lateral walls. Volume limited two adjacent blades, the hub and side walls in the form of an obelisk, forms a compartment (pocket) of the wheel for receiving and retaining water from the power system. Flat blades provide smooth filling water compartments (pockets) water wheels, and in the lower position contribute water to spill out of the compartments at the lowest point during the rotation.
The problem is solved by the fact that in the hydraulic portion of the device consisting of a housing with installed two water wheels, new is symmetric placement of water wheels relative to the axis of the conduit, which ensures uniform filling of the compartments water wheels and improves the hydraulic characteristics of the stream. This improves the throughput of two to three times the power density of the device. In addition, the device simultaneously performs the function of camera, water wheels, which contributes to simplification of the structure and size of the main host device, where the energy conversion of water into the energy of rotational motion.
The device is simple to manufacture, can be made of sheet metal or of wood. The design is there is no useless space filled with water, without producing useful work.

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.
