SU10874A1 - Propeller water turbine - Google Patents

Description

In the proposed water turbine, there is an elastic propeller, a blade, by changing the pitch of it, and hence its elevation angle, the turbine is adjusted. By appropriately maintaining the latter's mode of operation, it is possible to obtain the most advantageous coefficient of efficiency, by changing not only the angle of the jet entrance and the amount of water flowing through the turbine, but also the indicated variable curvature of the blade.

In FIG. 1 shows a side view of a helical water turbine, the body of which is shown in a longitudinal section; FIG. 2-screw water turbine in longitudinal section.

The propeller of water on the turbine (Fig. 1 and 2) has an elastic screw blade 1, encircling the spindle-shaped small sleeve 2, which forms a part separate from the turbine. The sleeve 2 is provided with slots 10 with fingers 5 placed in them, attached to the ends of the blade 1 held by the finger b on the sleeve 2. The finger b is pivotally mounted in a special socket of the latter comprising pistons 7, 7 that are integral or connected to fingers 5 and sliding or sliding with the help of the rod 9 and the solid rod 8 entering into it. The pistons 7, 7 are rotatably connected to the rods 8 and 9, and in the same way, the latter do not participate in the rotation of the sleeve 2; upper piston

made split for connection with the rod 9. The cylindrical surfaces of the pistons 7, 7, which fit tightly to the machine tools of the sleeve, make it impossible to pour out through the slots 10 the oil filling the free cavity of the sleeve 2. By changing the pitch of the helical blade 1, when the rods 8, 9 are moved the turbine stroke will be adjusted in addition to adjusting it by changing the angle of jet entry and water quantity. Thus, the required mode of operation of the turbine can be set using a third variable.

The subject of the patent.

Screw water on a turbine, characterized by using an elastic screw blade 1, enclosing a spindle-shaped hollow sleeve 2 separate from it with slots 10 for fingers 5 attached to the ends of the blade 1 held by a finger b, rotatably mounted in a special socket of said sleeve 2, the inner pistons 7, 7, which are integral or connected to the fingers 5 and moved or moved apart by the tubular bar 9 and the entrance to it with the continuous bar 8, in order to control the turbine - by changing the pitch, and therefore flax and elevation angle of the screw blade; the sleeve 2 is filled with oil, f
