Composite type savonius rotor

 

(57) Abstract:

The invention relates to wind and hydropower and for type Savonius rotors used in wind power and hydraulic motors. The essence of the invention: composite type Savonius rotor has two blades made of a composite of individual plates, mounted on a small space. What's new is that one of the longitudinal end sections of each flap bent inward of the blade and is made in the form of a wing with back facing the external side of the flap and the opposite end section of the flap is placed in relation to the adjacent flap overlaps and forms with it the confuser in the outer side of the blade. 2 Il.

The invention relates to wind and hydropower and for type Savonius rotors used in wind power and hydraulic motors. Allows you to increase the ratio of energy use renewable energy sources (wind, water currents), as well as the power rotor.

Known Savonius rotor, comprising two cylindrical blade in the form of semi-cylinders are parallel to the axis of rotation of the rotor (Shefter J. I. and other Inventor on wind turbines and wind turbines. M: Selhozizdat, 1957, S. 19).

the CMOS and low power rotor set sizes.

Closest to the invention is a composite type Savonius rotor containing cylindrical blades made of a composite of individual plates, mounted with small intervals (USSR patent 12,548, CL F 03 D 3/06, 1926).

However, the potential slot design of the rotor in a known solution is to use the incomplete utilization of the flow remains relatively small.

This invention is directed to solving the problem of increasing the capacity of the rotor and increase the utilization of renewable energy sources.

To increase the utilization of energy flow and power of the rotor of the same size, in the existing type Savonius rotor comprising two cylindrical blades made of a composite of individual plates, mounted with small intervals, one of the longitudinal end sections of each plate bent to the inside of the blade and is made in the form of a wing with back facing the external side of the flap and the opposite end section of the flap is placed in relation to the adjacent flap overlaps and forms with it the confuser in the outer side of the blade.

The invention is illustrated certainties blades 1, consisting of separate curved plates 2, each having one end bent portion 3 and is designed as a wing, and the second is the wall confuser 4.

The device operates as follows.

In the position shown in Fig.2, the stream runs onto the concave part of the blade 1 and presses the flap 2 with the power of R1forming a torque of M1relative to the axis of rotation of the rotor. When this part of the air (water) exits through the slit-confuser 4, where the flow is accelerated. Reactive effects of it on the blade (-R2) creates a torque M2. When the charge flow at the bent portion of the flap wing 3 creates a lifting force R3and the corresponding torque M Total torque will be M1+ M2+ M3that significantly exceeds the torque (power) of the described rotor in comparison with the known.

The device is industrially applicable, easy to manufacture. Composed of the same elements, except for the most remote from the center of rotation of the short flap.

Composite type Savonius rotor, comprising two cylindrical blade made of composite of individual plates that are installed with abolishable and made in the form of a wing with backrest, facing the external side of the flap and the opposite end section of the flap is placed in relation to the adjacent flap overlaps and forms with it the confuser in the outer side of the blade.

FIELD: hydropower engineering.

SUBSTANCE: invention is designed for use in lower power hydroelectric power stations. Proposed hydraulic turbine contains housing with end face covers, intake and exhaust branch pipes. Housing accommodates two rotors and streamlined guide. Rotors are made of made tubes provided with longitudinal cut and installed so that part of tube plays part of plate and other part plays part of rotor housing. Hydraulic turbine is furnished with system including pump, distributing device and pipelines providing pressure of water in tandem spaces between plates and housing.

EFFECT: reduced labor input in manufacture of hydraulic turbine.
