Description

The invention relates to hydropower, in particular to hydropower plants that can be installed at various depths and operate at any time of the year.

The aim of the invention is to increase the power of a damless all-weather hydroelectric power station at the same dimensions of the product, or to reduce the dimensions of a given power by increasing the length of the blade inside the casing / bringing it into operation earlier and strengthening the strength of the movable part of the structure.

This goal is achieved by the fact that inside the free space of the hollow cylinder, an inner blade is made in the form of a freely fixed curtain, which, when the outer movable blade is opened, is a continuation of it and works together with it, and is covered by the outer one in the oncoming flow section and passes it a hundred whose water was lifted (or deflected) by the sash to pass water, did not bear a dynamic load, and gave resistance only by friction of water on the surface of the sash and grate.

The hollow cylinder (or drum) under the outer blade, unlike the prototype, is not jacketed, the blade rests on the skeleton of rigidity, which, when the movable blade is opened, allows water to be discharged onto the wings of the inner blade and begin to work earlier before all steps of the outer blade are opened. The valves of the inner blade (their number will depend on the diameter of the drum) under the pressure of the discharged water are placed on the grate and even before the entire outer blade is opened, its head is received, and with the full opening of the outer one, they form a single blade, which can have a

But a bend with a radius of the cylinder or internally can take the form of a rectangle, which will depend on the class of the hydroelectric power station. The inner edge of the inner blade during rotation of the mixture with a small rounded guide forms an inner cylinder (small), inside which a gear wheel is made, from which, similarly to the prototype, the energy is removed to the electric generators. This gives a wider opportunity to choose the diameter of the gear impeller, which is often necessary when taking into account the speed and dimensions of electric generators with a multiplier. It also facilitates the standardization of the gear impeller, and consequently, the multiplier from the electric generator for small, medium, large rivers or a different flow rate, because the choice of the impeller will depend on the stability of the hydraulic unit in the flow, often on the width of the support that is inside it. This will allow the inner and outer blades to be calculated taking into account the largest energy withdrawal from the stream.

The length of the blade (therefore, its area) in the prototype increases with the same cylinder height hL ((drum he) due to an increase in the diameter of the cylinder and at a low height (low flow depth) the increase in the length of the blade l is restrained by strong calculations (more reliable when). In the claimed device, an increase in the length of the blade due to its internal part does not affect the strength of the outer part of the blade, and moreover, the presence of an additional small circumferential guide and lattice, on which the shutters of the inner blade lie, reinforces the entire structure uw, particularly its movable portion -usilivayut axis and the attachment point thereon outer movable blade.

Due to the fact that when the first stage of the outer blade is opened, the inner blade comes into operation, the outer blade can consist of only two steps. The design of the prototype, to ensure uniform rotation of the impeller, requires, especially with a small number of drums, three or more steps. For the same reason, a cylinder can consist of only two drums about the inventive device; this, in addition to a significant simplification of the design, makes it possible to have a stronger outer blade - it is easier to get closer.

When making reliable support, the design of the hydraulic unit can allow the blade to increase due to its internal part by more than 1.5 times. An increase in power by the same amount with the same dimensions of the product will not reduce its efficiency (when transferred to an increased area of the blade), because the inner part of the blade comes into operation immediately with the beginning of the opening of the first stage of the outer blade and the pressure head at this moment gives more power to the hydraulic unit than it will lose due to the training of the wings and the grill against water when they pass through it the working part of the circle. (Estimated calculations show that the exact balance will give the experiment).

The design and operation of the all-weather damless hydroelectric power station-11 (BVGES-11), consisting of two drums with an internal blade, is explained in the following drawings and diagrams.

The all-season damless hydroelectric power plant-11 (BVGES-11) contains a vertical body (hollow cylinder) 1, mounted on a support 2 and made

composed of drums 3 mounted on top of each other, fastened together and provided with four outer rotary blades 4 and four inner blades 5. The gear impeller 6 is connected with the inner edge of the inner blades, which, when rotated, form an inner hollow cylinder 7 (small ), and by means of a mechanical transmission (multiplier) 8 is connected to the main and backup generators 9 and 10 in a waterproof case, mounted on a support 2, Or in some designs a gear impeller 6, a fur the transmission (multiplier) 8 and the generators 9 and 10 are carried out in a single closed chamber, which is formed as part of the inner cylinder 7, with the solution of cooling the generators in another known manner. At the top and bottom of the housing 1, eight brackets 11 extend from the support, on which, in large and small circles corresponding to the diameters of the outer and inner cylinders 1 and 7, rollers 12 are made in a pivot pin, which are included in the circular guides on the top and bottom of cylinders 1 and 7 with a groove downward — a guide in a large circle 13 and a guide in a small circle 14 — whereby the rotating part of the structure rotates with a toothed impeller 6. Moreover, the top of the cylinders 1 is suspended on the rollers 12, and the bottom rests on them (see figure 9). In large cylinders, for example, at sea depths, it is possible to strengthen the fastening of the rotating part even in the middle, also through the fixed brackets with rollers and the guide of the inner cylinder 7.

The outer rotary blade 4 is made of two stages 15 of different lengths with a common axis of rotation 16, each on its hinges 17 (two axis of rotation are possible for each stage located next to each other, which will depend on the size of the hydraulic unit and strength calculations). Steps

15 are installed in the order of increasing their length from the drum 3, moreover, close to the axis

16 is small, 1/2 of the total length is completely sheathed, and the second frame has a window 18, made at the axis of rotation 16 with a size equal to the near step, so that when folded they form a single blade 4. The bottom and top of the stage 15 of the blade 4 are provided with flexible connections (cable) 19 and are connected last in pairs with the corresponding steps 15 of diametrically opposed blades. Flexible links 19 pass through guides 20 formed on the surface of the drum,

or part of them on a support through a small cylinder. The blade 4 has a curvature with a radius of the drum, sheathed with hard light material. The flexible link 19 holds the fully open outer blade 4, providing a L of 85 ± 2 °. The steps 15 of the outer blades 4 for faster lifting are provided with grooves 21 with a height of 20-30 mm, with a total area of up to 10% of the area of the step. The inner blade 5 is, as it were, a continuation of the outer blade 4 and is a free-hanging curtain made of several vertical strips of metal, plastic, etc. (quantity

5 will depend on the diameter of the product), adjacent in the working part of the flow to the metal grating 22 and freely rising on the opposite branch of the flow, or deviating when fastening the strips on

0 lateral edges, which will depend on the size of the hydraulic unit and working conditions.

The axis of rotation 16 of the outer blades 5 of the drum 3 are offset relative to each other by 45 °, as in the prototype. To equalize 5 nl of dynamic load, a mechanical transmission with electric generators is located approximately in the middle of the hollow cylinder in the upper or lower drum 3, depending on the design feasibility, and the stiffeners of the upper and lower drum stiffeners are fastened to the gear impeller 6 through the grill 22 by means of spokes 23 of the inner the edges of the inner blade 5 about eight points. Those.

5, all eight blades of two drums are rigidly fastened to the gear impeller, and thus the grill 22, fastened to the large and small guides 13 and 14, together serve as the basis for the rigidity of the rotating part of the structure, the top of which is suspended on the rollers 12, and the bottom rests on them. Therefore, the sides of the grating 22 are; outer - axis 16 of rotation of the blade 4, inner - leading needle 23

5 toothed impeller 6.

The inner hollow cylinder 7 (small), which is believed to be formed by rotation of the spokes 23, can be sheathed with a waterproof fabric, rubber, or the like. It will increase

0 Efficiency of BVGES-11 and will facilitate maintenance of rotating units in one hundred water by divers in large structures.

The outer hollow cylinder 1 (large), which, we believe, is formed by rotation

5, the axis 16 of the outer blade 4, unlike the prototype, does not have a cylinder jacket, and only four sections 24 that are not covered by folded blades are sheathed. Sheathed section 24 contributes with the still not open first stage

15 of the outer blade 4 equalizing the flow at a depth of this drum, and this provides a clearer operation of the flaps of the inner blade 5. (Refer to Fig. 7, where the top plan shows 16 steps of 8 blades of 2 drums at one time. The dots show the window 18 of the blade 4, and the dotted line shows the inner blade 5 of the lower drum 3. Also, according to this scheme, we can trace the passage of one blade of any drum at all points of the circle. right the sides — the working flow, lie on the left side on the flow stream. AVSD — the main points of passage of the blade during rotation: A — beginning to open each stage; B — zenith of the work of a fully open blade; C — beginning of folding of each stage; D — beginning of passage of the folded blade site with the highest drag). The outer blade 4 in the oncoming flow in the SDA section lies on the stiffening frame of the large cylinder 1 and together with the sheathed section 24 covers the side of the cylinder, providing the inner blade 5 in this section with standing water. The valves of the inner vane 5 pass through the SDA section, having risen (or deviated, in some designs) on their hinges, forming a free passage to water and giving resistance mainly by friction. Before starting work, the inner blade 5 passed point A in relatively calm water, driving in or rejecting its wings, because Before the first stage was opened, it was protected from the high-pressure head by a vast section 24 and the first stage 15 of the blade 4. The opposing swirls of water from the forward blade 4, which could prevent the flaps from lying on the grate, would be insignificant, because in front, going at this time has already passed the point of greatest resistance to flow C and enters the shadow.

All the forces that reduce the power of the installation, you are an experiment. They will enter the generalizing energy conversion coefficient t, but we will consider the frictional drag force RTp of the inner blade during the passage of the SDA section mainly with the aim of identifying the reasons that could reduce their influence.

VCp is the speed of movement of the hearth or object in it, m / s. We define V as the rotation of the cylinder, which will be considered equal to 1 / 2V of the flow (impeller under load);

S is the area of the wetted surface of the inner blade, m, we take as the double area of the blade (friction on both sides).

If the outer lobe can reduce Ptr, decrease Sn.n. due to its earlier pressing against the cylinder, this is not observed at the inner blade. For the inner blade, RTp, as we see from the formula, can be reduced due to better streamlining in the blade cusps, and also so that Vcp 1 / 2Vn, t b. so that there are no counter turbulent flows between the large and small cylinders in the SDA section. Evaluation calculations show that a decrease of 1 due to the RTp of the inner blade 5 will not exceed 1.5%, and taking into account the outer blades will not exceed 4%.

In order to increase the dimensionless drag coefficient (Cx), the inner blade 5 can be made with the curvature of the radius of the outer cylinder 1 in a single unit with the outer blade 4, which will depend on the class of hydroelectric power station.

For a more complete energy withdrawal, each stream asks for its HVHP size. Depth, speed, flow width are the main determining factors when choosing the diameter and height of the cylinder, and therefore, the length of the blade, although practice will make it necessary to take into account the need to standardize units and assemblies of HPPs, the technical capabilities of manufacturing a gear impeller and linking it with a multiplier and: even the availability of industrial generators. The reliability conditions of the outer blade should be based on the assumption that the greater the flow rate, the closer the length of the outer blade 1P should be to the height of the drum bb. The size of the inner blade depends not so much on its strength as on the stability of the product in the stream, which often depends on the width of the support. But not always the width of the support will take part of the length of the blade. For example, in the derivation channel, made specifically for BVGES-11 with recesses on the shore for them (Fig. 5), it is possible to have high flow velocities of 10 m / s or more, which require reliable wide support, but the installation of BVGES in a coastal indentation may allow the stability of the support not to be due to its width. Low flow rates, on average I m / s, can allow 1p / pb 5/1 and, therefore, the design will be large

at low altitude, it will take power from the stream due to the increased blade. The advantages of creating an internal blade and some other issues that explain the design and operation of BVGES-11 will be considered with small tolerances in the following examples.

The Moskva River opposite the VNIIG-PE building (30, Berezhkovska Naberezhnaya) has a low water depth of m, a flow velocity of m / s, and a flood of m, 25 m / s. (The Moscow river in the city has m, V up to 1.6 m / s, with a backwater dam V only 0.3-0.5 m / s, when opening the locks - collecting water - V up to 2 m / s). If we install here the pedaled BVGES-11 consisting of one hydraulic unit, then we will calculate the parameters as follows. The height of the cylinder, consisting of two drums, is determined for a low-water level of 4 m (0.8 m will be left on the ice formation and 1.2 m back from the bottom, m). Since the Moscow River has a low flow rate, we can take the limiting ln / hn 5/1. Consequently, at will be m, and the area of the hydraulic unit blade under the influence of flow at any moment of rotation of the cylinder m, C calculations of prototype 1l is within 1 / 8-1 / 6 of the length of the circumference of the cylinder, consequently, the diameter of the cylinder m. We will analyze how much you can increase the blade due to the internal. free part of the cylinder. In the prototype, the width of the support was calculated, and from it on the levers were fed rollers to the cylinder shirt, on which it rotated with the working gear. In the claimed device, the diameter of the gear impeller is determined by the width of the support, since it is installed behind the support and the length of the blade will increase from its rim to the core frame of the outer cylinder. The author believes that in the analyzed example, the width of the support is about 7 m with a reliable foundation and extensions from the ends of the levers to the top and bottom of the support, they will fully ensure the stability of the structure and provide space for placement inside its low-speed electric generators in a protective casing with a multiplier. Therefore, the diameter of the gear impeller can be 10 m and the length of the blade will increase due to the inside by 5 m. The total area of the blade under the influence of the flow will be m2. It should be noted that the increase in the blade by one and a half times does not weaken the outer part of it at all. her axis was reinforced with a grill. Given that with the beginning of the opening of the first stage, the inner blade immediately enters into operation, we can have only two steps at the blade

instead of four, as in the prototype, I have the right to expect that its increase will not reduce the energy conversion coefficient of y (when recalculating to a new blade area),

Moreover, it can have a curvature with the radius of the cylinder, just like the outside. Therefore, if the prototype at low water (m / s) gave power kW, in flood (.25 N-.C) kW, then now with the same

dimensions it will give 21 and 41 kW, respectively. Along the way, we note that the installation with m2 and; 0.7 PRI, 5 m / s will produce kW, at m / s it will produce kW, and in the channel of the drainage, where you can achieve

m / s will give N 21000 kW.

Let us examine another example of the implementation of BVGES-11, now for narrow mountain rivers with shallow depths and high flow velocities (Caucasus, Issyk-Kul, etc.). Suppose we are interested in rivers with a depth of 0.6 m (ford) and a width of the active part of the stream of 1.5 m. We will carry out BVGES-11 on rails that will serve as the foundation and basis for collecting the entire structure on them. We define the height of the slide equal to 0.1 m. For a vertical enclosure, we will waterproof the casing of the electric generator (low-speed will give a lot of weight, dimensions that will strengthen the design and

foundation). The lower rollers are run on the slide, and the upper feeds on the levers from the casing. We take the cylinder height equal to 0.5 m (we will exclude ice formations on mountain rivers, and if they are, they are insignificant and the heat removed from the electric generator will help them fight at this point). Consequently, the height of the drum is 0.25 m. In order to block the active part of the flow, the length of the common blade is not less than us

1.5 m. (Installing a wall or two in the river to concentrate the flow on the blade of the plant's efficiency. At shallow depths, their implementation, as a rule, is not associated with great difficulties). We make the outer blade of two steps with a length of 1.0 m. Therefore, we take the diameter of the outer cylinder to be 2.0 m, and we can determine the inner cylinder to be 1.0 m, which is quite enough to place an electric generator in it in a casing with a multiplier, the more we can take it up out of the water. Consequently, the inner blade will be 0.5 m long and the total area of the blade under the influence of flow will be 0.75 m, which, at 0.7, can give

power at m / s 14 kW, at 5 m / s - 66 kW, at 7 m / s - 182 kW. The function is enhanced by clogged crutches through the rails and with a stone overlay on them. This design can be transported in a truck, which during installation will help to tow the BVGES-11 on a slide in the stream. If the river is compressed by the banks, then it is possible to install BVGES-11v into the prepared excavation in the shore, as shown in FIG. 15. Despite the sharp difference in power due to different flow rates, the hydraulic unit for similar depths can be standardized, and an electric generator with a multiplier can be installed in it for a given speed.

The installation of BVNES-11 in various streams, including sea currents, is similar to the prototype, of course - more power requires more reliable support. The support of whole-cast, without internal space (such as the support of large bridges), will require another technical solution for the placement of an electric generator with a multiplier and linking them with a gear impeller.

The invention of BVGES-11, in comparison with the prototype, has a larger blade with the same dimensions, and its growth due to the internal free part of the product in designs with high flows can be less than 1.5 times. For example, on the Yenisei River in the area of the city of Igarka, where the width is practically unlimited, there are constant depths of 20-40 m, and in places up to 50 m, you can have a hydraulic unit of the same diameter and height as in the prototype, which consists of only of two drums with a blade area under the influence of the flow is 1.6 times larger, with a stronger outer blade due to its additional linking with the grill, without lowering the efficiency due to making the inner blade curvilinear, and bringing it into operation earlier. Thus, in a prototp at НЦ 30-35 m, with a diameter of 70-75 m, consisting of three drums at 1п / П2 3/1, m2 is expected. With these dimensions, the BVGES-11 can consist of two drums with m2 with the best 1p / pb 2/1 plus with the axis of the outer blade, connected not only with the skeleton of rigidity of the outer cylinder, but also with the grill. (The diameter of the inner cylinder is in the range of 14-15 m).

For a given capacity, BVGES-11 has a wider geography of use compared to the prototype. This is especially evident in the example of its use on narrow shallow rivers with large V, which require smaller dimensions and a more reliable lobe. For example, in the second example given in the description, where, 75 m,, 0 m,, 5 m, the prototype for such a blade should have the following dimensions: if, 0 m, then ITsNZ, 75 m; or if, 5, then c), 0 m. A

this does not fit into the reduced stream 0.6 m deep and 1.5 m wide, whereas in the claimed device this blade will be fully loaded in this stream,

therefore, in the broader and deeper. This also indicates a wider possibility of standardizing BVNES-11 as a whole or of its individual main components. Based on the latter, it is easier to approach

0 the issue of generating energy without a dam on any river. For example, even on one such as the Katun River, although an analysis of the dynamics of the components of the water balance of this river shows that the bulk of the water is formed

5 here due to seasonal snow cover, summer precipitation, and long-term reserves of firn and ice, and this regime speaks in favor of a high-pressure dam hydroelectric power station. (So, the annual runoff for flood is

0 in the village of Elagnda 71-78%, in the village of Srostka - 52-88%; water consumption in m / s amounted, for example, in 1976 near the village of Elanda: the largest - 4000, the smallest open channel -364, the smallest winter only 57; at the village of Srostki

5 respectively -4060, 449, 57.7). Taking into account the negative phenomena during the creation of the dam and the great need of this kral for electricity, we consider several schemes for removing energy from the transient flow of the Katun River

0 for local needs and industrial importance by the hydraulic units of the claimed device.

In the place of the bend, straighten the channel, profile it to the place of merging with a uniform slope or ledges, as the terrain and economic feasibility will show; lining the bottom and the shore with solid material, thereby achieving the highest V. BVGES-11 should be installed in the coastal notch according to one of the options, as shown in FIG. 15, at a distance from each other, ensuring equalization of the flow and the average minimum winter flow of water (he, Court of Water Cadastre

5 river Katun within 75 m / s), block the channel from above with plates to prevent freezing in winter, then the derivation channel-tunnel can allow a hydraulic unit operating all-weather with a blade under a load of about 6 m, with a reliable ratio of the outer blade In / he close to 1/1. In the channel-tunnel, we have the right to expect Y 0.8 due to the operation of the hydraulic unit, as it were, in the nozzle. Ten

5 hydraulic units, summarized in one building of BVGES-11, can produce all-season power of about 25 mW, which is about 250 mW. Summer discharge of water can be left along the old channel or a diversion channel can be made taking into account its passage along

top of the tonellas and take off the energy in stages by other additional summer hydraulic units that will be conserved for the winter. Evaluation work shows that, taking into account the relatively smooth decrease in the water level in the open channel over a period of months, the energy can be removed in three stages and the calculation can be done as follows: 1st - for the average annual maximum water flow, 2nd - for the average annual average and 3- e - for the average annual non-name of it. The Court of Water, the cadastre, they are different at the Katun River as 3, 2, 1, and are approximately equal: May, June, July - 900 m / s (the highest average monthly discharge is June, for example, the village of Elanda 1750 m / s in 1979); August, September - 600 m / s: October, but - 300 m3 / s. BVGES-11 is made of three hydraulic units mounted on top of each other above an all-weather channel-tunnel. The water passage mode allows immediately after discharging ice to connect all three hydraulic units, and then, after a drop in water, the upper ones are switched off one after another. It is possible to make a support for each hydraulic unit, which will depend on the channel profile, their arrangement in it, the flow velocity and the distance of alignment of the flow from one to the other hydraulic unit. Estimated calculations show that in the summer period it is possible to additionally generate energy, although not stable, but during the period of the greatest discharge of water, ten times more than the all-season channel will provide.

For local needs, it is possible to install separate BVGES-11 directly in the riverbed or in coastal indentations. The best effect will be shown by places squeezed between the rocks, sections of the profiled channel, cleared and, if possible, already made as high as the largest possible runoff.

These schemes are suitable for many rivers and it is economically more profitable to use an inventive device than a prototype, not only because it has more power with the same dimensions, but also because it has a wider possibility of use on any the river. This is especially evident in a river such as Podkamenna-Tunguzka, which has many different tributaries with large V - for a length of 1865 m, water withdrawal comes from 18026 large and small rivers. Taking into account that this uninhabited region is extremely rich in fossils and waiting for cheap energy, while the construction of a high-pressure hydroelectric power station will give a cheap kilowatt hour, but transferring it to large distances will negate this advantage, the construction of the BVGES-11 - Actually close to the consumer, although less powerful, will be more economical.

Due to the high power at the same dimensions as the BVGES-11 prototype, it is economically more profitable to use it when working in conjunction with an accumulating hydroelectric power station as flow quenchers in the outlet channel section at large pressure hydroelectric stations, in ocean currents, and also in tidal - casting currents in straits (such as in the English Channel) that change direction and speed.
