ROTARY STRUCTURE FOR OPEN CHANNELS Russian patent published in 2013 - IPC E02B13/00 

FIELD: construction.

SUBSTANCE: structure comprises a chamber placed between a supply channel 1 and a drain channel, and the bottom of the chamber is arranged below the bottom of the supply channel at the elevation of the drain channel bottom. The chamber is divided into galleries with a wall 3, parallel to the axis of the drain channel, with a horizontal shelf with a visor in the upper part, directed towards the supply channel. The bottom of the supply channel is made with a slant at the sharp angle to the horizon. In the end of the supply channel 1 there is a vertical wall 9 installed, as well as a jet-directing system. The jet-directing system is made in the form of vertical longitudinal walls 10, ends of which are aligned along the bottom of the inclined section parallel to each other and at the angle 10-15° to the axis of the closed gallery. The walls of the bottom of the inclined section under a separating shelf are arranged with reducing height. In the end of the separating shelf there is a vertical plate installed with a gap to the bottom of the drain channel with a hinged joint 13 and with a spring, which is connected to the separating shelf. A protective visor 15 is fixed to the side wall of the gallery above the horizontal separating shelf.

EFFECT: higher efficiency in operation due to reduced water head upstream a unit with wave structure of a flow.
