Description

The invention relates to hydraulic engineering and, in particular, to devices for treating stagnant waters of bays and bays by water of coastal currents passing by them in transit. It can be used to clean river bays by directing currents into their stagnant waters and enhancing water circulation in them.

A known map (Fig. 1) of the Black Sea marine currents (htth: //blacksea-map/ru/map_black_sea_current_map576665_0_0.htm). It shows currents encircling the entire Black Sea, including currents near the coast with velocities of up to 40 cm / s, passing near the Gelendzhik Bay (Fig. 2), but not entering it, as well as in Tsemess and other bays resort cities of the Black Sea (Gelendzhik and its environs. Krasnodar, 1964: Kolesnikova A.A., Kazitsin V.V., Scheglov D.E., Gelendzhik. Guide-book, 2nd ed. Krasnodar, 1969). Therefore, water circulation, for example, in the Gelendzhik Bay is slowed down - the current velocity in it is insufficient - 1 cm / s, which negatively affects the ecological state of this bay, there are accumulations of pollution in the form of garbage, sediment and floating inclusions.

Closest to the proposed invention is a device for the treatment of water in the waters of bays (patent No. 2479690 class IPC B02B 15/00, publ. 04/20/2013, bull. No. 11), including a block of one or more curved screw pipelines connected by side sides and mounted in one block, which is fixed on the flow path of coastal currents to change the direction of part of the water flows, increase their speed and introduce these flows into the water area of the bays, with each screw pipe made bent at an angle from 45 ° to 170 ° with multiple bottom screw surface provided with screw grooves inside and outside the screw pipe at an angle to its axis in the form of pockets of a polygonal shape in the form of various geometric shapes with four or more sides, the distance between straight bending lines equal to the length of each element of the polygon, while the pockets along the inner and outer surfaces can vary in both shape and size around the perimeter of the screw pipe, mounted from sections, each of which is made in the form of a circular sector, and made from a strip rolled into a ring with a multifaceted surface and the formation of different-sized quadrangles with two parallel sides parallel to each other, while the sections are connected to each other by the free sides of the said quadrangles in the form of a hollow screw pipe.

A disadvantage of the known device is the limited technical capabilities and manufacturing complexity.

The technical solution is the purification of stagnant and polluted waters of bays and bays by creating a constant circulation of clean sea water inside them with the help of the invention by turning and directing coastal currents in their water area, increasing the speed of artificially created currents with subsequent discharge of pollution into the open sea bays and bays, expansion of technological capabilities, simplification of design.

The technical solution is achieved by the fact that in the device for treating stagnant waters of bays and bays, including a block of one or more bent pipelines connected to each other by sides and mounted in one block, which is fixed to the flow path of coastal currents to change the direction of part of the water flows , increasing their speed and introducing these flows into the water area of bays, bays, each pipeline is made in the form of a sector of circular tubular section, on the outer and inner surfaces of which we have broken helical lines and helical surfaces and which is made of sections, each of which is mounted from a strip bent to one side along straight lines placed at an angle to the edges of the strip, with alternating formation along the strip length of different sizes of equilateral and isosceles triangles, on the two sides of the largest equilateral triangle, two identical isosceles triangles are located with their bases, on the sides of which are two identical equilateral triangles with two identical isosceles triangles located to them with their bases, on one of which an equilateral triangle is located, the sides of smaller equilateral triangles differ from the sides of large equilateral triangles by the same linear value, and the sections are connected to each other by the free sides of the mentioned triangles.

According to the patent literature not found a technical solution similar to the claimed, which allows us to judge the inventive step of the proposed device for the treatment of stagnant water in the waters of bays and bays.

The novelty is due to the fact that the pipeline is made with the formation on its outer and inner perimeters of multi-helical surfaces and multi-helical lines, which provides not only a change in the direction of water flow, the direction of their flows in the waters of bays and bays, increases the circulation of water, ensuring their purification, but and expands technical capabilities and simplifies manufacturing.

The novelty of the proposal lies in the fact that along the inner surface of each pipeline broken lines and helical surfaces are formed, which increases the intensity of movement and transportation of masses of water, expands technological capabilities.

The novelty is due to the fact that each pipeline is made in the form of a sector of circular tubular section, on the outer and inner surfaces of which broken lines and helical surfaces are formed, which provides not only the intensification of the movement of water masses and their transportation to the water area of bays and bays, but also the expansion of technological of opportunities.

The novelty is due to the fact that the elements from which the pipeline is assembled are different in terms of area, shape and size around the perimeter, so the technological capabilities are expanding.

The novelty is also due to the fact that the pitch of the helical lines is variable, i.e. changes around the perimeter of the pipeline, which violates the stationary motion of water masses and expands technological capabilities.

The novelty of the proposal also lies in the fact that along the entire perimeter of each pipeline, the cross-sectional area changes not only in shape, but also in area, which provides alternate compression and expansion of water flows in each section of the pipeline, and hence the expansion of technological capabilities.

The novelty of the invention lies in the fact that the elements from which each pipeline is assembled are not only inclined to each other, but also to the axis of symmetry of the pipeline, so the degree of compression of the masses of water increases, technological capabilities expand.

The novelty is also seen in the fact that each pipeline is made in the form of a sector of circular tubular section, on the outer and inner surfaces of which broken lines and helical surfaces are formed, and made of sections, each of which is mounted from a strip bent to one side in straight lines placed at an angle to the edges of the strip, with alternating formation along the length of the strip of different-sized equilateral and isosceles triangles, which simplifies the manufacture and extends technological capabilities and.

From the map of the currents, for example, the Black Sea (Fig. 1), it can be seen that along the coast there are surface currents moving along the coast at a relatively high speed, sufficient to clean coastal waters of debris and various contaminants. However, if the coast of the sea has in-depth bays, for example, like the Gelendzhik bay (Fig. 2), then surface currents, including deep ones along the coast, pass by bays in transit and only a small part of such currents penetrates into such bays of the sea coast. In addition, in certain coastal areas of the sea in settlements, for example, in Anapa, dams were built that blocked access to the sea currents, and as a result, stagnation zones of the waters of bays were created in the coastal waters of such cities, which worsens the ecological situation in such artificially created bays, as well as natural, as in figure 2.

The proposed device for the treatment of stagnant water in the waters of bays and bays (Fig. 3, Fig. 4) is made in the form of a block 1 of one or more bent pipelines 2, made in the form of a sector of circular tubular section, interconnected by lateral sides by known methods, for example, mounted in one block 1, poured along the perimeter with concrete in the form of a pyramid along the entire length of the pipelines 2.

The pipeline 2 (Fig. 5, Fig. 6) is made in the form of a sector of circular tubular section, on the outer and inner surfaces of which broken lines and helical surfaces are formed and which is made of sections 3, one of which is highlighted in Fig. 5 by triple lines 34 -35-26-16-25-34. Four broken helix lines are formed on the outer and inner surfaces of the pipeline 2, for example, as shown in FIG. 5 by a thickened line: a broken helix 4-5-6-7-8-9-10-11-12, a broken helix 13- 14-15-16-17-18-19-20-21, 22-23-24-25-26-27-28-29-30, 31-32-33-34-35-36-37-38- 39 (in Fig. 5, the invisible sections of helix lines are shown by two parallel lines: solid and dashed lines, and the invisible points of a broken helix are taken in parentheses).

Section 3 is made of strip M (Fig. 7, Fig. 8), bent to one side along straight lines A, B, C, D, D, E, G, placed at an angle to the edges of strip M with the formation of alternately different sizes equilateral 40, 41, 42, 43 and isosceles 44, 45, 46, 47 triangles. At the same time, on the two sides of the largest equilateral triangle 41, two identical isosceles triangles 45 and 46 are placed with their bases (double lines in Fig. 8). The bases of the triangles 45 and 46 are larger than the sides by the same amount, for example (Δ). Equilateral triangles 40 and 42 are placed to the lateral side of triangles 45 and 46, the sides of which are smaller than an equilateral triangle 41, respectively, also by (Δ). To the sides of triangles 40 and 42, isosceles triangles 44 and 47 are placed with their bases. The bases (shown in Fig. 8 with triple lines) of isosceles triangles 44 and 47 are also larger than their lateral sides by a value (Δ). An equilateral triangle 43 is attached to the triangle 47, the sides of which are smaller than the triangles 40 and 42 by (Δ) and, accordingly, less than the triangle 41 by (2Δ). After bending the strip M along the lines A, B, C, D, D, E, Zh to one side, the ends of the strip M along the line are connected (shown in Fig. 8 with a triple line), for example, by welding to form section 3 (Fig. 8) . Sections 3 are connected to each other by the free sides of triangles 40, 41, 42, 43, 44, 45, 46, 47, for example, by welding (Fig. 9) with the formation of pipeline 2 in the form of a sector of circular tubular section (Fig. 5, Fig. 6).

As a result, on the inner and outer surfaces of the pipeline 2, in the form of a sector of circular tubular section between the broken helical lines, helical surfaces are formed from triangles of various shapes, sizes and sizes, and the pipe 2 itself has a through section, which varies in shape, dimensions of the sides and the cross-sectional area (Fig.6, Fig.10).

Thus, the pipeline 2 (Fig. 5, Fig. 6) is made around the perimeter in the form of a multi-helical surface with helical lines around the perimeter of the pipeline 2 and screw grooves 48, 49, 50, 51 (shown in Fig. 6 by double arches) inside the pipeline 2.

Pipeline 2 (Fig. 5, Fig. 36) with a helical surface along its inner and outer perimeters with the formation on its outer and inner surfaces of multi-helical surfaces and unidirectional multi-helical lines, as well as helical grooves, can be made in another way.

One or more curved pipelines 2 are connected to each other by the sides by known methods in one block. Figure 3, figure 4 shows a block 1 of six interconnected pipelines 2 in three rows, poured concrete. The design of the block 1, poured with concrete, is shown in figure 3 and figure 4.

11 shows a block 1 of four pipelines 2, mounted in one row and interconnected by sides by known methods and filled with concrete, i.e. made in the form of a wide plate. Such blocks can be installed in bays, where a sufficiently large width of the entrance to the bay. They will occupy no more than 1.5% of the entrance to the bay and will not impede navigation. Calculations show that for water purification along the shores of the Gelendzhik Bay, it is sufficient to mount block 1 of eight pipelines 2 in a row along the path of current flows. An approximate calculation scheme is attached.

On Fig presents a map of the bay mounted on the path of the coastal currents of the proposed device for the treatment of stagnant waters of the bays and bays with an indication of the direction of flow of water flows of coastal currents of the sea into the bay. Such blocks can be installed in bays, where the width of the entrance to the bay is sufficiently large, for example, in the Gelendzhik Bay, the entrance width is 1800 m.

Technical and economic advantages arise due to the rotation and direction of the flows of coastal currents into the water area of bays and bays with the help of the proposed device, which includes a block of one or more pipelines made in the form of a sector of circular tubular section, interconnected by lateral sides by known methods, which is fixed on the flow path of coastal currents and changes the direction of part of the water flows of coastal currents, directs them to the water area of bays and bays at a speed equal to the speed of coastal currents Nij, which enhances water circulation, a positive effect on the ecological status of bays and inlets, removes accumulated dirt, debris, sediment and floating inclusion in the open sea, extends the technological capabilities and simplifies manufacturing.

Methodology for calculating devices for cleaning stagnant waters of bays and bays

A technique is proposed for calculating the main parameters in the design and manufacture of a device for treating stagnant waters in bays and bays.

1. The length of the coast of the bay is 12000 m. With an average depth of 2 m and a width of a strip of water along the coast of the bay of 30 m, the volume of water along the entire coast of the Gelendzhik Bay is W≈L × B × H = 12000 × 30 × 2≈720000 m ³ .

The width of the entrance to the Gelendzhik Bay is 1800 m.

(Lotyshev I.P. Geography of the Kuban. Encyclopedic Dictionary. Maykop, 2008).

To create a favorable environmentally friendly environment in the waters of the Gelendzhik Bay, it is necessary to replace this volume of water within a given time T, for example, T≈240 hours.

The coastal current velocity in the region of Gelendzhik Bay V = 40 cm / s = 2400 cm / min = 2.4 m / min (Gelendzhik and its environs. Krasnodar, 1964: Kolesnikova A.A., Kazitsin V.V., Shcheglov D. E., Gelendzhik. Guidebook, 2nd ed. Krasnodar, 1969).

Thus, the flow rate through the pipelines of the device is equal to

$$Q\approx \frac{W}{T}=720000/14400\approx \mathrm{fifty}{\mathrm{<figure-callout\; id="3"\; label="m"\; filenames="00000006.png,00000008.png"\; state="\{\{state\}\}">m</figure-callout>}}^3/m\mathrm{and}n$$

At a flow velocity of V≈2.4 m / min, the cross-sectional area of the proposed device for treating stagnant waters of bays and bays is equal to

. $$S\approx \frac{Q}{V}\approx \mathrm{fifty}/2,\mathrm{four}\approx 20.83{\mathrm{<figure-callout\; id="2"\; label="m"\; filenames="00000006.png"\; state="\{\{state\}\}">m</figure-callout>}}^2$$

.

Therefore, for a shallow bay, such as the Gelendzhik Bay, the unit for treating the waters of bays and bays is mounted from eight pipelines connected to each other by their lateral sides in a row.

. Тогда ориентировочно поперечное сечение блока (показано на фиг. 11, при условии монтажа в плите восьми трубопроводов) по ширине будет составлять 18 м, по толщина 2 м.The cross-sectional area of one pipeline will be S ₁ = 2.6 m ² , which means the diameter of one pipeline $$D=\sqrt{3.3}\approx 1.82m$$

. Then the approximate cross section of the block (shown in Fig. 11, provided that eight pipelines are installed in the plate) will be 18 m in width and 2 m in thickness.
