SU15694A1 - Differential device for mating waterway pools - Google Patents

Description

In the present invention, with respect to drops with the use of a vertical narrowing shaft, this mine, in order to realize the most complete repayment of the energy of the water flow, is equipped with spiral-like guide ribs, and a silencer consisting of a system of curvilinear, expanding in vertical and horizontal directions, channels.

In the schematic drawing of FIG. 1 is a cross-section of the proposed device; FIG. 2 is a section along the line NN in FIG. one.

The vertical, narrowing downwards, shaft A (Fig. 2) is provided inside with spiral-shaped guide ribs a, as a result of which the fluid entering the shaft is rotated. Downstream, the stream enters a silencer placed under the shaft, divided by a series of walls at

horizontally and vertically expanding channels b, directing the split flow into the curvilinear widening channel enclosing the muffler.

The subject of the patent.

A differential device for coupling the pools of a watercourse, using a vertical tapering shaft, characterized (fig. 1-2) by the fact that the walls of the shaft, for the purpose of communicating rotational motion entering the flow of water, are provided inside with screw guide ribs a, and The lower part of the shaft contains a silencer consisting of a system of curvilinear, expanding in the vertical and horizontal directions, channels b, which serve to direct the split-1 flow into the curvilinear expanding channels surrounding the silencer.
