Description

Description of the invention

The invention relates to wind energy and relates to wind power plants with a large (single) power in a separate 2 instance. It should be included in the group of four inventions developed by me, which will form a single inventive idea: 1. "Pyramidal wind engine" Mo application 2003054162; 2. "Device for extinguishing shocks of the Armed Forces", Mo application 2003098521;

Z. "A device for limiting the revolutions of a pyramidal wind engine", Mo of the application is not yet known, although a postal notification of receipt of its UIPV came in 70. 4. "Device of a support node for PVD", Mo of the application is still unknown, although a postal notification has arrived about the receipt of its UIPV.

Wind energy is currently in the first place among alternative, ecologically clean and renewable energy sources (1Ї1. "Using only a hundredth of this (wind) energy, it would be possible to completely ensure the energy supply of the USSR" - says the article "Wind Energy" from BSZ - 2 |21.

Academician V. L. Pozdyunin also added great significance to wind energy. In particular, on ships of the water fleet |Z - p. 105). True, he has the APU as a source of electrical energy on the ship, but to present it as an aerodynamic drive of a propeller - "imagination" was not enough.

In the meantime, humanity is in search, and at the same time it is enough to familiarize yourself with the magazine "Boats and Yachts" (4-8).

In the era of the sailing fleet, the experience in the exploitation of wind energy was enormous |U - p. 183).

In those days, the concepts of "sailing" and "wind resistance" were commonplace. 105) are most suitable for the theoretical justification of the work of the pyramidal wind turbine (PVD) invented by me. The aerodynamic theory of N. E. Zhukovsky can help us in this to a very weak degree. So he had a different task. It is enough to quote his famous statement: "I believe that humanity will fly, relying not on the strength of its muscles, but on the strength of its mind!". "

In its development, the wind power industry is currently faced with great difficulties |1 - p. 74) primarily because it is based on a propeller borrowed from old mills - "windmills". In its pursuit of unit capacity of the Armed Forces, it is forced to build support towers higher and higher, that is, to develop vertically. With my project consisting of five inventions, I propose horizontal development. Under such conditions, much less metal and equipment will be needed for the APU, and it will be easier to maintain them, most importantly, it is possible to achieve much larger unit capacities in their individual copies.

A wind power station was built in California (USA) |1 - page 7b| with a thousand wind turbines, while using my invention, four will be enough! A thousand "-- pyramid wind turbines will be able to replace a modern large power plant (NPP, HPP, TPP), and millions of autonomous, local wind turbines will render unnecessary the currently operating systems of high-voltage power transmission lines with their large metal capacity, large energy leaks, land will be freed, etc. d. Reliability, stability and continuity will become a reality.

The PVD invented by me (see application Mo2003054162) contains a vertical axis of pyramid blades. In the form as it is presented in the application and on the explanatory letter, Mo1 to the valid application, we see that the axis is directly connected to the bearing block. This circumstance determines the efficiency of the PVD (with appropriate dimensions and the design of its blades) in the range of 15-20 kW. This statement is derived from my practical experience.

From" In the application "Support unit device for PVD" and on the letter explaining Mo2 to the valid application, we see another solution of the support unit, which allows (also with the appropriate dimensions of the blades) to significantly increase the power

PVD, approximately up to 110 kW, due to the creation of a static moment ("Archimedes' lever") using the device of consoles and support on them at three points of PVD. it. In order to obtain unit capacities of 150, 600, 1000 and 10000 kW, it will be necessary to carry out certain structural solutions. In particular, the lower bearing block must be unloaded, and the three ends of the cantilever part must rest on the chassis on a rubber track or on wheel pairs as in railway cars and move it - accordingly, it must be on an asphalt concrete surface or on a circular rail path (fig. 1, 2). -And I could not find 20 Developed close analogs to my real invention either in VPTB, or in the Russian State Library (Moscow), or in the libraries of Ukraine. c" The purpose of the invention is to expand the range and functional capabilities of the APU on the PVD with an excess of several times the unit power of the largest APUs with propeller engines currently operating in the developed countries of the world. 29 The essence of the invention is explained in fig. 1 and 2. here we see that the supporting ends of 1, solid spatial trusses v. 21, rest with the help of the damping and stabilization system 2 on the end part 3, and it, in turn, on the railway carriage 4, which moves along the circular rail path 5.

The end part C is part of the support node 6, which is described in the application under the name "Device of the support node for PVD". Only in the actual application it is given as an example that the APU can provide movement to the propeller 7 of a water 60 ship, for smooth movement from a place and smooth acceleration of which a hydraulic clutch or torque transformer 8 is used.

Three spatial trusses 21 in the central part converge, forming a node 9, on which the PVD axis 10 rests, to which, in turn, pyramidal blades 11 are attached sideways to one of the sides of their bases.

The geometric principles of these blades are given in the application Mo2003054162 under the title "Pyramidal wind turbine". Axis 10 is a pipe that can be several tens of meters long, with a relatively small diameter and small wall thickness. In fact, its function is persistent, not supportive. Steel pins pass through its cavity, fastening the blades together in the desired geometric position. The pins press them well to the axis, and the nuts are welded to eliminate the weakening of their action. Reinforcement will be formed inside the tubular axis due to passing pins. Its lower part is blocked, and concrete is poured through the upper part, which, after hardening, will make the entire system monolithic.

As can be seen in Fig. 1, the frame of each of the six pyramidal blades consists of spatial trusses of Javert (a Swedish engineer who first proposed a constructive solution in the form of stretched braces and braces) and tubular-corner elements 13. This makes it possible to make the design of the blades reliable, non-metal-intensive and 7/0 downtime.

Tubular-corner elements 13 (in Fig. 1 they are shown in the form of three lines, which are often crossed out) are pipes of small diameter (3/4 inch or 4 inches), which are covered by two corners, say, top and bottom (only the corners between do not touch each other) and are compressed either by tight-fitting clamps or tightly wound stainless wire. A system will be formed that is able to withstand significant loads and at the same time slightly change its geometric shape, i.e. it only slightly sags over many meters.

Separately, both the pipe and the corner, say, 10 meters long, give a very noticeable sag and are weak.

By connecting them, you can achieve such an effect, as, for example, in a reinforced concrete structure, where iron reinforcement and concrete mortar, joined together, formed the basis of the modern construction industry.

Both the pipe joints and the corner joints in my proposed design are well welded. However, when superimposed on each other, they (joints) should not coincide. Places of attachment in the corners should be slightly cut out so that they can fit tightly to the pipes and their welded seams do not interfere with this. At the ends of the tubular-corner elements, holes are made through the corner - pipe - corner for a collar of the appropriate size, or the corner - pipe - corner is flattened under the press, then the necessary holes are made. It is clear that these elements are connected to each other during construction and assembly work with fastening clamps.

I used this construction in my practical work, and it helped me out of a difficult situation.

In general, according to Fig. 1, it should be clear that the "framework of the empty part of the pyramidal blades" can be made due to tubular-corner elements. Then, it is performed again with wooden bars attached to it with clamps or tightly fitting stainless wire. Both the hollow part of the blades and the outer part, i.e. on both sides, are sheathed with plastic (sheet metal or sheets). There should be no protrusions or distortions anywhere. The wind flow should slide easily without resistance along the protruding parts of the blades, and it should also be easy to go from their hollow parts. In this context, plastic is the optimal tool in the fight against "parasitic" - aerodynamic resistances during the movement of PVD in a turbulent air flow. "-

The second tier of PVD practically eliminates the "dead spot", which can be observed with a single-tier design.

It also improves the traction characteristics of the wind engine. In its lower part, each of the pyramid-blades --

Zv rests on a beam (truss) 14, which at the same time fastens the blades of the lower tier together. In the upper part, the blades of the second tier are fastened with the help of ropes 15 and tubular-corner elements 16, which, in turn, are provided with a rope 17 with a spacer to strengthen them, which will form a truss of a simplified structure with its strength and hardness. After all, its length can reach several tens of meters. In this context, rope 15 also needs to be provided by the "automatic tensioning" scheme, which includes: fixed blocks 18, cable 19, and load compensator 20, so that it effectively fulfills its purpose (helping beam 14). can have many joints. They are usually made straight.

This creates a knock (noise) when the wheel pairs pass over them. But if the joints are made oblique, that is, when else;" the wheel has not left this rail, but is already entering the second, then the unwanted noise will be much less and the "road - wheel" system will also wear out less, and the thermal joint will remain.

Powerful APUs with support on a chassis (rubber, pneumatic or steel) should be located on the ground (in the middle of a field or on a hill), where there are no obstacles to the winds due to terrain folds or artificial structures. They can also be located on floating platforms or ships, which will not only be provided with electricity, but will even be able to provide movement to their propellers, although a better system is: APU - generator - electric motor - which drives the propeller.

On flat roofs of workshops of enterprises, residential buildings and between floors in through ventilation

In the corridors of high-rise buildings, their installation is also possible. Noise effects can be reduced to a minimum, up to 4) noise from the operation of elevators in a residential building due to proper structural design and noise-absorbing elements, for example, rubber gaskets, shock-absorbing devices.
