TWO-LEVEL TREATER OF STAGNANT WATER OF AREAS OF WATER OF BAYS AND GULFS Russian patent published in 2015 - IPC E02B3/02 E02B15/00 

FIELD: construction.

SUBSTANCE: device 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 in the form of a sector of round tubular cross section of spiral form with a multi-faceted helical surface along its internal and external perimeter with an inlet hole. The pipeline is made of sections, each mounted of two subsections. Subsections are made of strips bent towards one side along straight bending lines placed at the angle to edges of strips, and coiled into a ring with alternate formation of isosceles, equilateral and scalene triangles of various sizes along the strip length. Sides of triangles differ from each other by a linear value multiple to integer number Δ. At two sides of the largest equilateral triangle there are two identical scalene triangles arranged with their large sides, sides of which are less than the side of the largest equilateral triangle by the value Δ. To the middle side of one of scalene triangles there is a smaller equilateral triangle is fixed, sides of which are less than the side of the largest equilateral triangle by the value of 2Δ. To the second side of the smaller equilateral triangle there is an isosceles triangle fixed by its base, sides of which are less than its base by the value of Δ and the side of the largest isosceles triangle by the value of 3Δ. To the side of the isosceles triangle there is an isosceles triangle fixed, the base of which is less than its side by the value Δ and the side of the largest equilateral triangle by the value of 4Δ. At the opposite side to the middle side of the second scalene triangle there is an isosceles triangle fixed by its side, the base of which is less than its side by the value Δ and the side of the largest equilateral triangle by the value of 3Δ. To the base of the isosceles triangle there is an isosceles triangle fixed with its side, the base of which is less than its side by the value of Δ and the side of the largest equilateral triangle by the value 4Δ. At one side of the subsection there is a hole in the form of a square, the side of which is less than the side of the largest equilateral triangle by the value 3Δ, and at the other one there is a hole in the form of an isosceles trapezoid. The large base of the trapezoid is equal to the side of the largest equilateral triangle, and the smaller base is less than the larger base by the value of 3Δ. Sides of the trapezoid are less than the larger base by the value of 2Δ. Subsections are connected to each other by holes in the form of trapezoids to form sections with inlet and outlet holes in the form of squares. Sides of holes are equal to each other and arranged at the angle, the value of which determines the spiral shape of the pipeline. Sections of the pipeline are connected into a pipeline, by alternate rotation by 90° of each subsequent section relative to the previous one.

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