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, water circulation, 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.

The technical solution is the purification of stagnant and polluted waters of the water areas of bays and bays by creating within their constant circulation of pure sea water using the invention by turning and directing coastal currents in their water area, increasing the speed of artificially created currents with subsequent removal of pollution to the open sea bays and bays.

The technical solution is achieved by the fact that in a device for treating water in the waters of bays and bays, including a block of one or more bent pipelines with a wavy cross-sectional shape, 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 water flows, increasing their speed and introducing these flows into the water area of bays, bays, and each pipeline with a wave-like shape of the passage section is made bent at an angle ohm from 30 ° to 180 ° or more with a spiral-shaped step of a helix along the outer perimeter and a wave-like helical surface along the inner perimeter in the form of pockets of a wave-like shape, while a pipeline with a wave-shaped shape of the passage is mounted from sections with a wave-like multi-start screw surface of double curvature, equipped with screw grooves inside and outside the pipeline with a wave-like shape of the bore at an angle to its axis in the form of a ridges of a wave-like shape with centers of curvature located outside and inside the cross section of a pipeline with a wave-like shape of the passage section, is mounted from sections, each of which is made in the form of a circular sector, made of a strip rolled into a ring with the formation of different sizes of 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 pipeline with a wave the shape of the cross-section, with the formation along the outer and inner surfaces directed to one side at an angle to the longitudinal axis of the pipeline with a wave-like shape of the cross-section, wave-shaped screw surfaces in the form of pockets of a wave-like shape along the outer and inner surfaces that are along the perimeter of the pipeline with a wave-like the cross section can be different not only in shape but also in size, while the distance between the fold lines is equal to the sum of the lengths of the perimeters of the pocket’s geometric figures the inner and outer surfaces.

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 a wave-shaped cross-sectional shape and with a wave-shaped multi-start screw surface of double curvature, equipped with helical grooves inside and outside the pipeline at an angle to its axis in the form of wave-shaped pockets with centers of curvature located outside and inside the cross section of the pipeline with the wavy shape of the passage section, which provides not only a change in the direction of the flow of water, the direction of their flows in the waters of bays and bays, but also increases water circulation, ensuring their cleaning.

The novelty lies in the fact that each pipeline with a wave-like shape of the bore is made curved at an angle from 30 ° to 180 ° or more with a step of helical lines along the outer perimeter and with a wave-like helical surface along the inner perimeter in the form of pockets of a wave-like shape, while the pipeline with a wave-like shape of the passage section is mounted from sections with a wave-like multi-start screw surface of double curvature, equipped with intimate grooves inside and outside the pipeline with a wave-like shape of the passage section at an angle to its axis in the form of pockets of the wave-like shape with centers of curvature located outside and inside the cross section of the pipe with the wave-like shape of the passage section, mounted from sections, each of which is made in the form of a circular sector made of a strip rolled into a ring to form different-sized quadrangles with two parallel sides parallel to each other, with sections with are aligned with each other by the free sides of the said quadrangles in the form of a hollow pipeline with a wave-shaped passage shape, with the formation along the outer and inner surfaces directed to one side at an angle to the longitudinal axis of the pipe with a wave-like shape of the passage section, wave-shaped helical surfaces in the form of pockets of a wave-shaped on the outer and inner surfaces, which along the perimeter of the pipeline with a wavy shape of the passage section can be different not only in terms of but also in size, while the distance between the fold lines is equal to the sum of the lengths of the perimeters of the geometric figures of the pockets of the inner and outer surfaces, which expands the technological capabilities and provides a change in the direction of the water flow, directing their flows in the waters of bays and bays, and increases the circulation of water, ensuring their cleaning.

The novelty lies in the fact that the device for treating the waters of bays and bays includes a block of one or more curved wave-like pipelines with a wavy cross-sectional shape, interconnected along the perimeter and mounted in one block, which is fixed to the flow path of coastal currents to change direction parts of water flows, increasing their speed and introducing these flows into the water area of bays and bays, thereby increasing the speed of water circulation in them.

The novelty also lies in the fact that each pipeline with a wave-like shape of the flow cross section is made of bent at an angle from 30 ° to 180 ° or more with spiral pitch along the outer perimeter and with a wave-like helical surface along the inner perimeter in the form of pockets of a wavy shape, which not only changes the direction of the water flow, directing their flows in the waters of bays and bays, but also increases the circulation of water, ensuring their purification.

The novelty is due to the fact that a pipeline with a wave-shaped passage shape is made with a step of helical lines along the outer perimeter and a wave-shaped helical surface along the inner perimeter in the form of pockets of a wave-shaped shape, which along the perimeter can vary not only in shape, but also in size, which provides a change in the direction of motion of swirling fluid flows.

The proposed device for water treatment of 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 wave-like shape of the flow cross 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 pipelines 2 with a wavy shape of the passage section. The angle of bending of pipelines with a wave-like 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, figure 2, for example, the 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 wavy 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 wave-like shape of the bore, bent at an angle of 90 °, made as part of a torus (circular ring) with a wave-like helical surface along its inner and outer perimeter. Pipeline 2 with a wave-shaped passage shape 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 along the outer and inner perimeter of the pipeline 2 with a wave-like shape of the passage section of helical lines and helical surfaces of the wave-like shape, with centers of curvature located outside and inside the cross section of the pipe 2 with the wave-like shape of the passage section.

Pipeline 2 with a wave-shaped passage shape is made of sections 3 (Fig. 5) with a wave-like multi-start screw surface of double curvature provided with helical grooves inside and outside the pipe 2 with a wave-like shape of the passage section at an angle to its axis in the form of pockets of a wave-like shape with centers of curvature located outside 4, 5, 6, 7, 8, 9 (Fig.6) and pockets of curvilinear shape with centers of curvature located inside the cross section of the pipeline with a wavy shape of the passage section 10, 11, 12, 13, 14, 15.

Pockets of a wave-like shape on the outer surface 4, 5, 6, 7, 8, 9 (FIG. 5) and pockets of a wave-like shape on the inner surface 10, 11, 12, 13, 14, 15 around the perimeter of the pipe 2 with a wave-like shape of the passage section can be different not only in shape but also in size.

Each of the sections 3 is made of a strip 16 (Fig. 7), bent in a wave-like fashion along the fold lines 17 located at equal angles a to the longitudinal edges of the strip 16 and placed at equal distances L between the fold lines 17. The distance L is equal to the sum of the lengths of the perimeters of the geometric figures pockets of the inner and outer surfaces, namely the distance between points AB, BB, BB, GD, DE, EA.

Thus, each of the sections 3 is made in the form of a circular sector (Fig. 5) and is mounted from a strip 16 (Fig. 7, Fig. 8), on which rectangles 18 are marked (one of the rectangles is shown in Fig. 7 by a double line), and bend lines 17 located at equal distances from each other equal to the scan length of the perimeter of the wave-like pockets at distances L and at an angle α to the longitudinal edges of the strip 16.

On the strip 16, the trimming lines 19 of the edges of the strip 16, shown in FIG. 7 with a dash-dot line with two points, are also marked. After marking along the line of trimming of the edges 19, sections of the strip 16 (in FIG. 7 these sections of the strip 16 are shaded) are cut off and the strip 16 takes on the form shown in FIG. 8, in which the fold lines 17 of the strip 16 are different in length L ₁ , L ₂ , L ₃ , L ₄ , L ₅ , L ₆ with the formation at the same time of different sizes of quadrangles with two parallel sides - fold lines 19 parallel to each other. The strip 16 (Fig. 8) after trimming the edges of the rectangles 18 along the cutting line 19 is bent in a straight line placed at an angle α to the edges of the strip 16 with the formation of wavy surfaces AB, BB, BB, GD, DE, EA and then collapses into a ring 20 (figure 10) with a wavy surface. The wave-like strip 16 after folding into a ring 20 is connected by known methods, for example by welding, soldering, etc. along the transverse edges 21 and 22 (Fig. 8, Fig. 9) of the strip 16 with the formation of section 3 in the form of a circular sector.

Thus, the pipeline 2 with a wave-like shape of the passage section (FIG. 5, FIG. 6) is made around the perimeter in the form of a multi-start wave-shaped helical surface of the wave shape at an angle to the axis of the pipe 2 with the wave-like shape of the passage section.

Pipeline 2 with a wave-like shape of the passage section (Fig. 5, Fig. 6) with a wave-like helical surface along its inner and outer perimeter with the formation of pockets of a wave-like shape with a step varying in diameter of the working chamber can be made in another way.

One or more curved pipelines 2 with a wave-like shape of the flow cross section are connected to each other by the sides by known methods in one block. In Fig.3, Fig.4 shows a block 1 of six interconnected pipelines 2 with a wave-like shape of the passage section 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 eight pipelines 2 with a wave-shaped passage shape with wave-shaped pockets mounted in a 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 wave-like shape of the passage section in a 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 curved pipelines with a wave-like 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 waters of bays and bays at a speed equal to the speed of coastal currents, which enhances the circulation of water, positively affects the ecological state of bays and bays, removes accumulated pollution debris, sediment and floating inclusions in the open sea.

Methods for calculating devices for treating waters of bays and bays

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

1. The angle of the bend of pipelines with a wave-like 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, figure 2, for example, the 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 replace this volume of water within a given time T, for example, T≈240 hours.

The coastal current velocity in the area 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 wavy shape of the passage section of the device is equal to

$$Q\approx \frac{W}{T}=720000/14400\approx \mathrm{fifty}{\mathrm{<figure-callout\; id="3"\; label="m"\; filenames="00000004.png,00000008.png"\; state="\{\{state\}\}">m</figure-callout>}}^3/m\mathrm{and}n$$

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

. $$S\approx \frac{Q}{V}=\mathrm{fifty}/2,\mathrm{four}\approx 20.83{\mathrm{<figure-callout\; id="2"\; label="m"\; filenames="00000006.png,00000008.png"\; state="\{\{state\}\}">m</figure-callout>}}^2$$

.

Therefore, for a shallow bay, such as Gelendzhikskaya, the device block for treating the waters of bays and bays is mounted from eight pipelines with a wave-like shape of the flow cross section, bent at an angle of β≈60 °, connected to each other by their lateral sides in one row.

. Тогда ориентировочно поперечное сечение блока (показано на фиг 11) по ширине будет составлять 18 м, по толщине 2 м.The cross-sectional area of one pipeline with a wave-shaped cross-sectional shape 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) will be 18 m in width and 2 m in thickness.
