Description

The invention relates to hydraulic engineering and, in particular, to devices for treating stagnant waters of bays and bays by the 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_map 576665_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, the circulation of water, for example in the Gelendzhik Bay, is slowed down - the currents in it are insufficient - 0.1 mm / s, which negatively affects the ecological state of this bay, the accumulation of pollution in the form of garbage, sediment and floating inclusions.

Closest to the proposed invention is a device for the purification of water in the waters of bays (patent No. 2479690, class IPC E02B 15/00, publ. 04/20/2013, bull. No. 11), including a block of one or more curved screw pipelines connected to each other sides and mounted in one unit, which is fixed on the path of the coastal currents flow 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 one screw surface provided with screw grooves inside and outside the screw pipe at an angle to its axis in the form of polygonal pockets in the form of various geometric shapes with four or more sides, and the distance between the straight fold lines is equal to the length of each polygon element, while the pockets along the inner and outer surfaces can vary both in 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, made of 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 the waters of bays and bays, including a block of one or more pipelines bent at an angle, interconnected by the sides and mounted in one block, which is fixed to the flow path of coastal currents to change the direction of part of the flows water, increasing their speed and introducing these flows into the water area of bays, bays, the pipeline is made with the formation of triangular helical surfaces along its outer and inner perimeters th form and unidirectional multi-helix lines, while the pipeline is made of sections, each of which is made in the form of a circular sector mounted from a strip bent alternately in different directions along straight lines in the form of fold lines located on the strip at equal distances from each other and placed at an angle to the edges of the strip with the formation of different sizes of quadrangles with two parallel sides located on the strip alternately and parallel to each other, while the strip is folded into a ring with m a faceted surface, and the sections are connected to each other by the free sides of the mentioned quadrangles in the form of a hollow pipeline with a triangular shape of a flow cross-section, bent at an angle of 30 ° to 180 ° or more with the formation of outer and inner surfaces of triangular helical surfaces along its perimeter and unidirectional multi-pass helix lines.

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 treating 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 perimeter of multi-helical triangular helical surfaces and unidirectional multi-helical helical lines, which provides not only a change in the direction of water flow, directing their flows in the waters of bays and bays, increases water circulation, providing them cleaning, but also expands the technical capabilities and simplifies the complexity of manufacturing.

The novelty is due to the fact that the pipeline is made with a triangular cross-sectional shape and with a triangular multi-start screw surface, equipped with helical grooves inside and outside the pipeline at an angle to its axis in the form of triangular pockets, which provides not only a change in the direction of water flow, directing their flows into The water area of bays and bays, but also expands the technical capabilities and simplifies the complexity of manufacturing.

The novelty lies in the fact that each pipeline with a triangular shape of the bore is made bent at an angle of 30 ° to 180 ° or more with a diameter varying in the pipe with a triangular shape of the bore, which extends the technological capabilities and simplifies manufacturing.

The novelty is also seen in the fact that the pipeline is made of sections, each of which is made in the form of a circular sector mounted from a strip bent alternately in different directions along straight lines in the form of fold lines located on the strip at equal distances from each other and placed under angle to the edges of the strip with the formation of different sizes of quadrangles with two parallel sides located on the strip alternately and parallel to each other, while the strip is folded into a ring with a multifaceted surface, and the sections are connected to each other by the free sides of the said quadrangles in the form of a hollow pipeline with a triangular cross-sectional shape, bent at an angle of 30 ° to 180 ° or more, with the formation of the outer and inner surfaces of triangular helical surfaces and unidirectional multi-helix lines around its perimeter, which extends technological capabilities, simplifies manufacturing.

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 deep bays of the sea coast. In addition, in separate 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 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 at an angle of pipelines 2 with a triangular cross-sectional shape, 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 pipelines 2 with a triangular shape of the passage section. The angle of bending of pipelines with a triangular shape of the passageway of the device is determined by the geometry of the mouth of the bay, bay, or rather the angle between the direction of the coastal current of the sea and the tangent to the shore of the mouth of the bay, bay, in figure 2, for example angle β≈60 °. The boundaries of block 1 are shown by thickened lines with two points in FIG. 3 and FIG. 4.

The pipeline 2 with a triangular shape of the bore is made curved at an angle of 30-180 ° or more. For example, figure 5, figure 6 shows the pipeline 2 with a triangular shape of the bore, bent at an angle of 90 °, made with a triangular helical surface along its inner and outer perimeter.

A pipe 2 with a triangular shape of the passage section can be made of sections 3 (one of the sections in Fig. 5 is indicated by solid thickened lines), interconnected by known methods, for example, welding, adhesive, etc., with the formation of the outer and inner perimeter pipeline 2 with a triangular shape of the cross-section of helical lines and helical surfaces of a triangular shape.

The pipe 2 with a triangular shape of the passage section is made of sections 3 (Fig. 5) with a triangular multi-screw surface, provided with helical grooves inside and outside the pipe 2 with a triangular shape of the passage section at an angle to its axis in the form of pockets of a triangular shape.

The pipeline 2 (Fig. 5, Fig. 6) is made in the form of a torus (circular ring) made of sections 2 (one of the sections in Fig. 5 is indicated by solid thickened lines), interconnected by known methods, for example, welding, gluing, etc. P. Each of the sections 3 is made in the form of a circular sector (Fig. 5, Fig. 6) and is mounted from a strip 4, on which rectangles 5 are marked, on the diagonals of which there are fold lines 6 at equal distances from each other, one of the diagonals is a fold line 6, strip 4 is shown in FIG. 7 with a thickened line. On the strip 4 marked also are the trim lines 7 of the edges of the strip 4, shown in Fig. 7 by a dash-dot line with two points. After marking along the edge-cutting line 7, the sections of strip 4 (in FIG. 7 these sections of strip 4 are shaded) are cut off and strip 4 takes the form shown in FIG. 8, in which the fold lines 6 of strip 4 are different in length L ₁ , L ₂ , L ₃ , L ₄ , L ₅ , L ₇ , L ₈ , L ₉ , L ₁₀ , L ₁₁ , L ₁₂ , L ₁₃ , L ₁₄ , L ₁₅ , L ₁₆ . Strip 4 (Fig. 8) after trimming the edges of rectangles 5 along the trim line 7 is bent alternately in different directions along straight lines placed at an angle to the edges of strip 4 to form different-sized quadrangles with two parallel sides - i.e. diagonals 6 of rectangles 5 parallel to each other, and then collapsed into a ring 8 with a triangular surface, as shown in Fig.10. The edges 9 and 10 of strip 4 after folding into ring 8 are connected by known methods, for example, welding, soldering, etc. with the formation of section 3 in the form of a circular sector.

Thus, the pipeline 2 (Fig. 1, Fig. 2, Fig. 3) is made around the perimeter in the form of a multiple helical surface with helical lines around the perimeter of the pipeline 1 (one of the helical lines is shown in Fig. 5 by a thickened line 11-12-13 -14-15-16-17-18-19-20-21-22-23-24-25-26-27) and screw grooves inside the pipeline 1 in the form of pockets of a triangular shape at an angle to the axis of the pipeline.

Pipeline 2 (figure 5, figure 6) with a multifaceted helical surface along its inner and outer perimeter with the formation on its outer and inner surfaces of multi-helical surfaces of triangular shape and unidirectional multi-helical lines can be made in another way.

One or more curved pipelines 2 with a triangular shape of the flow cross section 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 with a triangular cross-sectional shape in three rows and filled with concrete. The design of the block 1, poured with concrete, shown in figure 3 and figure 4 thickened lines with two points.

11 shows a block 1 of four pipelines 2 with a triangular cross-sectional shape with triangular-shaped pockets 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 with a triangular cross-sectional shape in one row on the path of current flows. An approximate calculation scheme is attached.

On Fig presents a map of the bay with mounted on the path of coastal currents of the proposed device for the treatment of water in the waters of bays and bays, indicating the direction of flow of water flows of coastal currents of the sea inside 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 bent pipelines with a triangular cross-sectional shape, interconnected by lateral sides by known methods, which is fixed to the flow path coastal currents, changes the direction of part of the water flows of coastal currents and directs them to the water area of bays and bays at a speed equal to the speed of coastal currents th, which increases 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, the expansion of technological capabilities and ease of fabrication.

Methodology for calculating devices for treating the waters of bays and bays

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

1. The angle of the bend of pipelines with a wave-like shape of the passage section of the device is determined by the geometry of the mouth of the bay, bay, or rather the angle between the direction of the coastal current of the sea and the tangent to the shore of the mouth of the bay, bay, figure 2, for example angle β≈60 °.

2. 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 ensure the replacement of 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 of water through pipelines with a triangular shape of the passageway of the device is

$$Q\approx \frac{W}{T}=720000/14400\approx \mathrm{fifty}{\mathrm{<figure-callout\; id="3"\; label="m"\; filenames="00000008.png,00000009.png"\; state="\{\{state\}\}">m</figure-callout>}}^3/m\mathrm{and}n$$

At a flow velocity of V≈2.4 m / min, the cross-sectional area of the proposed device for treating the 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 Gelendzhikskaya, the unit for treating the waters of bays and bays is mounted from eight pipelines with a triangular cross-sectional shape, bent at an angle of β≈60 °, 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 8 трубопроводов) по ширине будет составлять 18 м, по толщине 2 м.The cross-sectional area of one pipeline with a triangular cross-sectional shape will be S ₁ = 2.6 m ² , which means that 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 8 pipelines are installed in the plate) will be 18 m in width and 2 m in thickness.
