DESCRIPTION OF THE INVENTION
The invention relates to wind power and relates to wind power plants with a large one in a separate (single) capacity. It must enter the developed group of inventions, which includes the following technical solutions: "Pyramidal windmill" with a vertical axis with paddle-blades, the axis directly connected to the bearing block, which determines the efficiency of the engine within 15-20 kW (see RU 2248463 C1, published on March 20, 2005), "Device for limiting the speed of a pyramidal windmill" (see RU 2003130043 A, published on 10.04.2005), "Mounting of a support unit for a pyramidal windmill", allowing to increase engine power up to 110 kW Due to the creation of a static moment (the "Archimedes lever") by means of the device of consoles and support on them at three points (see RU 2003131661 A, published on 10.04.2005), "Device for quenching shocks of a wind power plant" (see RU 2003128919 A , Published on March 20, 2005).
To obtain unit capacities of 150, 600, 1000 and 10,000 kW, certain constructive solutions will be required. In particular, the lower bearing block must be unloaded, and the three ends of the cantilevered part must rest on the rubber chassis or wheel pairs, as in railway wagons, and it must accordingly move along the asphalt pavement or along a circular rail track (Fig. 1, 2 ).
An analogue of the invention (prototype) of a wind power plant containing a pyramidal windmill with a vertical axis of rotation and blades is FR 2418996 A, cl. F 03 D 3/00, 02.11.1979.
The technical result consists in expanding the range and functionality of the installation, as well as in increasing the power, and is ensured by the fact that in a wind power plant comprising a vertical axis and blades of a vertical axis and blades, according to the invention, the blades are fixed about a vertical axis in Two tiers, with the three edges of the blades of the lower tier, through the cushioning and stabilization system, rest on the three supporting ends of the rigid trusses converging in the central part into the bearing and bearing block, the vertical axis is a pipe through which the steel studs pass, , While the axis with the hairpins is embroidered inside with concrete, and the framework of the blades consists of rigid spatial trusses and tubular-angled elements. Each of the pyramid-blades of the second layer rests on a beam, simultaneously securing the blades of the lower tier, the attachment of the blades of the second tier in the upper part is carried out by means of ropes and tubular-angled elements, which in turn are equipped with a rope with a spacer, forming a truss, This rope has a system of automatic tension, which includes fixed blocks, rope and cargo compensator. The support ends of the trusses are supported through their end part on the chassis: rubber, pneumatic or steel, when it rests on a rail cart moving along a circular rail track.

1 shows a wind power plant (general view); FIG. 2 shows an end portion of the supporting ends of the trusses mounted on the annular rail track; FIG. FIG. 3 shows a view A-A of FIG. 2. FIG. The wind power plant comprises the following elements: the support ends 1 of the rigid spatial trusses 21 are supported by the cushioning and stabilization system 2 on the end part 3, and it, in turn, on the rail car 4 that moves along the ring rail track 5. This steel path as one Of the possible options: maybe even wheel, rubber and pneumatic. |
The end part 3 is a part of the support unit 6, which is described in the application entitled "Installation of a support assembly for LDPE". Only in the present application, as an example, it is shown that an APU (wind power plant) can propel a propeller 7 of a watercraft, for smooth starting and smooth acceleration of which a hydraulic coupling or torque converter is used.
Three spatial trusses 21 in the central part converge, forming a node 9 on which the axis of the LDP 10 rests, to which, in turn, the pyramidal blades 11 are fastened to one side of their bases. Geometrical principles of these blades are given in the application No. 2003107582/06 Under the name "Pyramidal windmill". Axis 10 is a pipe, it can be a few tens of meters in length, a relatively small diameter and a small wall thickness. In fact, its function is stubborn, not support. Through its cavity pass steel studs, which hold the blades 11 together in the desired geometric position. The studs press them well against the axis 14, and the nuts are brewed to prevent weakening of their action. Inside the tubular axis 10, reinforcement is formed due to the passing studs. The lower part of it is damped, and concrete is poured through the top, which, hardened, will make the entire system monolithic.
As can be seen in FIG. 1, the frame of each of the six pyramidal blades 11 consists of the trusses 12, 21, 22 and the tubular-angled elements 13. This allows the construction of the blades 11 to be reliable, non-metal-intensive and simple.
Tubular corners 13 (shown in FIG. 1 as three lines that are often crossed out) are small diameter pipes (3/4 inches or 4 inches) that are enclosed by two corners, from above and from below (only the corners are not interconnected Contact) and are compressed either tightly fitting yokes, or tightly wound with stainless steel wire. A system is formed which is capable of withstanding significant loads and at the same time slightly changing its geometric shape, i. E. For many meters it only weakly sags. Separately, both the pipe and the 10-meter-long corner give a very noticeable slack and are fragile. Connecting them, you can achieve such an effect, as, for example, in a reinforced concrete structure, where reinforcement from iron and concrete mortar, joining together, formed the basis for modern construction industry.
Both the joints of pipes and the joints of the corners in the proposed construction are well welded. However, when superimposed on each other, they should not coincide. The application points in the corners should be cut so that they can fit tightly to the pipes and their weld seams would not interfere with this. At the ends of the tubular-angled elements 13 holes are made through the corner - a pipe - a corner under a clamp of the appropriate size, or a corner - a pipe - the corner under the press is flattened, then the necessary holes are made. It is clear that these elements are joined by fastening clamps during construction and assembly works.
In general, the casing of the hollow portion of the pyramidal blades 11 can be formed by the tubular-angled elements 13. It is then re-made by wooden blocks, clamps attached to it or by a tight-fitting stainless steel wire. Both the hollow part of the blades 11 and the outer one, i.e. On both sides, is lined with plastic (lining or sheets). There should be no protrusions or curvatures anywhere. The wind flow should easily, without resistance, slip along the protruding parts of the blades 11 and easily escape from their hollow parts. In this sense, plastic is the optimal tool in the fight against "parasitic" aerodynamic drags during the motion of LDPE in an air turbulent flow.
The second layer of LDPE practically excludes a "dead point", which can be observed with a single-tier structure. It also improves the traction characteristics of the wind turbine. In the lower part of each of the pyramid-blades 11 are supported by a beam (truss) 14, which simultaneously secures the blades 11 of the lower tier. In the upper part of the blade 11 of the second tier are fastened by means of ropes 15 and tubular-angled elements 16, which in turn are reinforced by a rope 17 with a spacer, which forms a truss of a simplified design with its strength and stiffness, the length of which can reach several tens Meters. In this sense, it is also necessary to wire 15 so that it effectively fulfills its mission (assisted beam 14), provide an automatic tension circuit, which includes fixed blocks 18, cable 19 and cargo compensator 20.
The circular track 5 due to its curvature can have many joints. They are usually made straight. This creates a knock (noise) when wheel pairs pass over them. But if the joints are made oblique, i.e. When the wheel has not left the rail yet, but already goes into the second one, the undesirable noise will be much less and the "path-wheel" system will wear out less and the temperature joint will remain.
Powerful APUs with support on the chassis (rubber, pneumatic or steel) should be located on the ground (among the field or on a hill), where winds are not disturbed due to folds of terrain or artificial structures. They can also be located on floating platforms or ships that will not only be provided with electricity, but even be able to propel their propellers, although the APU system is better-the electric motor that drives the propeller.
On flat roofs of shops of enterprises, apartment houses and between floors in through ventilation ducts of high-rise buildings and their installation is possible. Noise effects can be reduced to a minimum, to the noise from the operation of elevators in the residential building, due to proper design studies and sound-absorbing elements, for example rubber gaskets, shock absorbers.
