ACCESSORY FOR TREATMENT OF WATERS OF AREAS OF WATER OF BAYS AND GULFS Russian patent published in 2015 - IPC E02B15/00 E02B3/02 

FIELD: construction.

SUBSTANCE: accessory comprises a block of one and more pipelines bent at the angle and connected to each other by sides. The block is fixed on the path of coastal flows. The pipeline is made with formation of multi-pass helical surfaces of triangular shape at its external and internal perimeter and unidirectional multi-pass helical lines. The pipeline is made of sections. Each section is made in the form of a circular sector mounted from a strip bent alternately to different sides along the straight lines in the form of bending lines. Bending lines are placed on the strip at equal distances from each other and are placed at the angle to edges of the strip to form quadrangles of different size with two parallel sides arranged on the strip alternately and parallel to each other. The strip is coiled into a ring with multi-faceted surface. Sections are connected to each other by free sides of specified quadrangles in the form of a hollow pipeline of triangular shape with throughput section. The throughput section is bent at the angle from 30° to 180° and more to form along its perimeter an external and an internal surfaces of multi-pass helical surfaces of triangular shape and unidirectional helical lines.

EFFECT: treatment of areas of water of bays and gulfs by direction of flows in their stagnant waters and increasing water circulation.
