Vertical turning vanes pivotally connected with the disk. The deflecting device is designed as a slip bands are installed on the ends of racks mounted on the bottom under the half of the wheel from the shore with the possibility of deviation of the shoulder to the horizontal position. A pair of blade - strip is made of steel or plastic. Axle raise a few tens of meters and dropping. The verticality of the fall of reach is temporarily fixed on the upper end of the stabilizer. 2 S. p. f-crystals, 6 ill.

The invention relates to hydraulic machines and engines, in particular to water-wheels, and can be used to generate electricity, actuation of machines and mechanisms. Water wheel, mainly intended for use on rivers with gently sloping banks and small watercourses, and to obtain large torque effort.

Known water wheel (turnstile), consisting of hollow elements: stand with dome drive articulated Zakka ropes with a concrete floor.

This design is complicated and has more resistance when rotating from the air cavities of the blades and their deviations up from higher density, down from less relative to the volume of water displaced by them.

Closest to the claimed invention is a water wheel that contains the horizontal drive vertical rotary blades, the vertical axis of rotation, the lower end of which is rigidly fixed to the bottom of the stream.

The use of this wheel on the river with gently sloping banks requires a beam with powerful legs to secure the top axis, and on the small watercourses does not allow you to use a large part of the bed and get a large torsional force.

The purpose of the invention is the expansion of the scope.

This goal is achieved by the fact that water wheel containing the axis fixed on the bottom of the watercourse, a horizontal disc mounted on an axis vertical turning vanes, pivotally connected with the disk, provided with a deflecting device. The latter is in the form of slip bands are installed on the ends of racks mounted on the bottom under the half of the wheel from the shore. Band slide has the opportunity to reject the blades of the tx2">

How hard fixing axis is performed by raising it to a height of several tens of meters and drop, and the vertical drop is achieved temporarily fixed on the upper end of the stabilizer.

In Fig. 1 shows a water wheel, side view; Fig. 2 is a waterwheel, a top view; Fig. 3 - axle wheel side; Fig. 4 - temporarily-installed the stabilizer of Fig. 5 - axis raised to a height of Fig. 6 - axis, fixed in the bottom of the stream.

Water wheel consists of axis 1, rigidly fixed to the bottom of the watercourse, which dressed the disk 2 with vertical hinged, rotatable blades 3, which have the ability to deviate from the vertical position to the plane of the disk on the hinges 4 with deflecting device made in the form of slip bands 5, mounted on the ends of the uprights 6, mounted on the bottom of the watercourse under half of the wheel from the shore. Moreover, a pair of blade-lane slide is made of steel or plastic. Axis 1 has rigidly fastened to it, the locking flange 7 located on the bottom level. When docked in soft soils (silt, sand, sandy loam, loam, clay, etc., below the flange 7 on the axis 1 is arranged anchor 8 in the form of the stabilizer ptx2">

On the blades 3, which is in a vertical position, receives the flow of water and brings them into rotation together with the drive 2. This blade 3, facing the deflecting device to be rotated in a horizontal position, sliding on the strip 5 against the flow with a small hydrodynamic water resistance and sliding friction. For deflecting device of the blades 3 are lowered in a vertical position under the action of its own gravity and take the pressure of the water.

The hard way of fastening of an axis of the water wheel at the bottom of the watercourse is as follows.

In the preparatory work includes strengthening removable, consisting of the two halves of the stabilizer 9 on the upper end of axis 1 by bolts 10. Further, the axis 1 for loop 11 lines 12 and an external suspension bracket 13 is attached to the helicopter 14, which picks up and transports it to the installation site. Lifting axis at the calculated height is determined as a result of calculations and full-scale tests, the crew drops her down. The verticality of the fall of the axis is provided temporarily strengthened stabilizer 9 and weak soils, the anchor 8. Reaching the necessary speed, axis 1 pierces the bottom of the watercourse to the locking flange 7, which, ntah, the anchor 8 is fully included in the bottom. For rocky and pebbly soil anchor 8 is not needed, because their strength is sufficient to withstand operational loads from a water wheel. After this a temporary stabilizer 9 is removed and the axis 1 is mounted water wheel, and under its coastal half of the deflecting device, by driving the racks 6 in weak soil, seminolecounty concrete in rocky.

The proposed design of the water wheel and the method of fastening its axis in the bottom of the watercourse allow to extend the scope through the deflection of the blades, moving against the flow in a horizontal position and release part of the space under the coastal half of the wheel.

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.
