Description

Turbine with tipping blades

Technical field

The invention relates to a tip-blade turbine, particularly for bi-directional fluid flow or in bi-directional fluid flow systems and devices.

BACKGROUND OF THE INVENTION

Existing methods of hydropower conversion are solved by classical turbines, using the water pressure created by the water level difference created by the dam. In low-slope locations, rectilinear turbines with controllable distributor and controllable impeller or fixed distributor solutions are known, which are mostly used for stable flows because they have a small control range. The prior art turbines utilize the pressure of water entering and leaving the turbine in the direction of the impeller axis of rotation.

The essence of the technical solution

These drawbacks of the current solutions are overcome by a tipping turbine comprising an impeller, which is mounted in an arrowhead distributor, characterized in that bearings are mounted around the periphery of the impeller, in which one end of the tipping vane is mounted with the other end of the shafts. with the swivel blades is mounted in bearings located from the inside of the flywheel and where the locking rings are formed on the sides of the impeller circumference. Recesses are formed around the periphery of the impeller in the direction of the locking rings.

Industrial applicability

The technical solution can be used especially in the areas for bi-directional fluid flow or in systems and devices with bi-directional fluid flow.

Overview of the drawings

The technical solution will be explained according to the attached drawing. Exemplary embodiment

The turbine according to FIG. Consists of an impeller 1 in which a shaft 9 is supported via a tongue 8. The shaft 9 is supported in bearings 7 mounted in an arrowhead 6. The arrowhead 6 forms a statically fixed part of the turbine. Center wheel 1 is secured against displacement segment 10. When the fuse .kola periphery of the impeller 1 are mounted bearings 2, in which one end of ^one shaft bearing 3

3. Tilting blades 4 are welded to the shafts 4. The other ends 3 ' ^{1 of the} shafts 3 with welded tilt blades 4 are supported in bearings 2', which are mounted in the flywheel 5. On the sides 11 of the impeller circumference 1, locking rings 12 are formed. and 12 *. A circumferential recess 13 is formed around the periphery of the impeller 1 in the direction of the locking rings 12, 12 'for the movement of the swivel blades 4. The locking ring 12 is supported

The flaps 4 are supported on the locking ring 12 ¹ when the fluid flows in one direction and the fluid flows in the opposite direction. The turbine according to the invention is located in a pipe (not shown) or two-way fluid flow system.

When the liquid flows in one direction, the tilting vanes 4 swivel to their working position, their maximum opening being blocked by the locking ring 12. In the opposite direction of liquid flow, the tilting vanes swivel to the second working position, their maximum opening being blocked by the locking ring 12 ¹ . The direction of rotation of the impeller 1 and the flywheel 5 is always the same in both directions of fluid flow.
