DESCRIPTION OF THE INVENTION

The invention relates to the field of electric power and is used for electricity production using alternative sources, namely the radiant energy of the sun and air flows.

There are devices that use solar energy, such as solar heaters, details of which are given in the author's certificate USSR N SU 1615484 A1 (ICI-5 F 24 J 2/10), which is designed to use solar energy to heat. It comprises a fixed hemispherical mirror reflector and a fixed heat sink and kontrotrazhatel in the form of a spherical segment.

However, such a device can not be directly used as a power plant.

and are known to power plants that convert the energy of natural air currents (wind) into electricity, the data of which are given in the patents of Ukraine and copyright certificates of the USSR. For example, published in the Bulletin of Ukraine "Promyslova vlasnict" (Industrial Property) N 2-94 five patents by the same author (Budrevich Czeslaw Constantine Albinovich) of N 1594 (MKI-4 F03D 1/06, wind turbines); N 1597 (MCI-5 F 03 D 3/02, wind power unit); N 1592 (MKI-4 F 03 D 5/02, wind turbines Ch-K.A.Budrevicha); N 1598 (MKI-4 F 03 D 7/02, wind turbines); and N 1593 (MKI-4 F 03 D 5/02, wind turbines) and others.

Known and electric power plant for converting energy of natural air currents (wind) into electricity, as described in the patent of Ukraine N 21028 A, IPC-5 F 03 D 1/00. Electric plant contains a wind wheel kinematically connected to the power take-off shaft connected to a generator and gearbox located on the column or mast.

In all these devices for converting wind energy into electrical energy applied wind turbine, which comprises a support mast arranged thereon and cowl frame with blades or wind wheel is kinematically coupled with the PTO shaft connected to an electric generator. These devices are one of the main components of a power plant that uses wind power as a natural flow of air, but this arrangement is bulky and is largely dependent on the presence of wind and opening areas.

and venting devices known to use to create an exchange of air (ventilation). Such devices are described in many literature and patent sources, in particular in the Official Journal "Promyslova vlasnist" N 2-94 and N 3-94 (entered in the State Register of Ukraine). For example, data on the ventilation device comprising a stack mounted above the extractor hood, having a radial ejector channels (patent of Ukraine N 1554 MKI-4 F 24 F 7/02. Ventilation device), or flexible ventilation air duct, comprising separate sections , each of which has a frame and a flexible membrane (patent of Ukraine N 1556 MKI-4 F 24 F 13/02. flexible ventilation air line).

However, these devices are designed to create ventilation and can not be directly used as a power station.

There are devices designed to enhance traction, for example, taken up for consideration and published in the Bulletin (Ukraine) N 3-94 Application N 94020502, MCI-5 F 02 K 1/00, F 02 K 9/00 to the centrifugal traction power engineering and Prokhvatilova z., which consists of a source of fluid flow to the nozzle.

However, this device itself requires an additional energy input and can not be directly used as a power plant.

The closest in technical essence to the claimed technical solution is the power plant according to German patent (see. DE 4104770 A1, cl. F 03 D 9/00, 20.08.1992), which comprises a block converting mechanical energy into electrical energy with an electric generator connected thereto, and sun block conversion of radiant energy into mechanical energy through the thermal configured as solar cells.

This device, like the previous ones, uses primarily natural air currents (wind), and to a lesser depending on the availability of wind in the area and its closure is also the radiant energy from the sun through solar panels. However, this device does not provide full independence from wind currents, which leads to some limitation in application.

In addition, all the above mentioned devices are mainly intended for industrial facilities. At the same time there is a great need for power sources that could be used and at the household level, such as the power of small estates, gardens, etc.

The basis of the technical solution given the task - to create a resource-saving electric power plant, which provides electricity through the use of alternative sources of energy and thus can be used both in industry and for domestic purposes, or as a backup power consumers. At the same time, compared with the prototype gets extension application task, completely regardless of the winds in the area and its closure.

The problem is solved in that the power plant comprises a block converting mechanical energy to electrical connected thereto an electric generator, and a block conversion of radiant energy of the sun, formed as a vertically mounted tube of variable cross section, with the expansion of the upper and lower sections and narrowing in the middle part of the tube , the tube is made of two different materials stacked on the longitudinal plane of the pipe, one of which is transparent, and the other with the inner surface with the greatest degree of absorption of radiant energy. Unit converting mechanical energy into electrical energy is designed as a frame with blades and located in the most constricted portion of the tube with the orientation of the blades perpendicular to the pipe axis. The whole apparatus is installed in a place where the most favorable conditions are provided for the sun light pipe, with the transparent part is oriented toward the sun's rays.

Moreover, for maximum efficiency of the plant, the lower portion of the tube is covered with a bottom surface of a material similar to the material of the pipe opposite the transparent part - namely, the material with the greatest degree of absorption of radiant energy. From the lower edge of the transparent portion of the tube an opening formed between the bottom pipe section and inclined in a direction from the top opening by the transparent part of the tube down to the opposite side of the tube. The highest efficiency can be obtained at an inclination angle ^{o 30-40.} Moreover, by the vertex angle (bottom of the tube opposite the transparent part of) the absorbent surface is in the form of one or more platforms arranged approximately perpendicular to the rays of the sun.

In addition, for more effective use in a clock installation of insufficient sunlight heating, especially at night, in the bottom of the pipe can be further installed burner, which can further enhance the thrust in the pipe.

The essence of the invention is illustrated by the drawing, which shows:

	Figure 1 - a general view of the apparatus in section; Figure 2 - embodiment of the lower part of the plant (section); FIG. 3 - embodiment of the bottom part of the plant with additional elements.

FIG. 1 is a perspective view of an electrical installation, which comprises one unit of radiant solar energy conversion unit 2 and converting mechanical energy into electrical energy. Block 1 is designed as a vertically mounted tube 3 with an extension variable cross-section in the top 4 and bottom 5 and narrowing section in the middle part 6 of the pipe 3. The pipe 3 is made of two parts 7 and 8, the longitudinal sostykovanyh pipe section 3.

Part 7 is made of transparent material such as transparent glass or fiberglass, and the other part 8 is formed with an inner surface 9 with the greatest degree of absorption of radiant energy, for example painted black paint, etc. Block 2 convert mechanical energy into electrical energy is placed in the most constricted portion 6 of the pipe 3. The unit 2 comprises a base frame 10 on which is mounted an electric generator 11, the shaft of which (directly or through a reduction gear) are connected wind turbine blades 12. The turbine 12 is oriented such way that the blades are mounted perpendicular to the axis of the pipe 3. The whole apparatus is installed in a place where the most favorable conditions are provided for the sun light pipe, while it is transparent part 7 is oriented toward the sun's rays, which are depicted as arrows S.

FIG. 2 shows an embodiment of a bottom in the installation section, wherein the tube 3 (with a transparent part and an opaque 7 - 8) is covered with the bottom 13 of the material surface with the greatest degree of absorption of radiant energy; from the lower edge portion 7 of the transparent tube 3 provided with an opening 14 formed between the bottom of the pipe section 13 and 15-15 inclined in the direction of opening by the transparent top of the tube down to the opposite side of the pipe at an angle , The optimal value of which lies in the range ^30-40 o, and from the vertex 16, the absorbing surface is made in the form of one or more platforms 17 located approximately perpendicular to the rays of the sun S.

FIG. 3 shows a possible embodiment of the bottom of the unit when the bottom of the burner tube 18 is further installed.

Operation of the apparatus is explained in FIG. 1. The sun's rays (shown as an arrow S) light pipe 3 and through its transparent part 7 pass to the inside of the pipe 3. Reaching the opposite side of the surface 9 8 3 pipe, the sun's rays are absorbed, so that the radiant energy of the sun is converted into heat. 9, the surface is heated, which in turn heats the surrounding air within the pipe. The heated air in the pipe leading to the creation in its flow along the pipe 3 upwards (indicated by the arrow V). Thus, the radiant solar energy is converted into mechanical energy of moving air (so-called traction Combustion). Block 2 receives the air flow and energy using a wind turbine blade 12 drives the electrical generator 11. As a result, the proposed setup allows electric power to generate electricity, using alternative sources of energy, particularly energy in moving air pipes (traction) enhanced action of radiant energy sun. Power from such a plant depends pipe sizes (its height and cross-section) and the intensity of solar rays which fall on the active surface of the absorbing part of the tube.

Work additional elements, placed in the lower part of the apparatus illustrated FIG. 2. When the ceiling bottom of the tube bottom 13 with increased active surface luchepogloschayuschey surface. With the same purpose made platform 17, which on one hand is closed inefficient acute angle near the point 16, and on the other hand when you install these areas perpendicular to the sun's rays help to increase the concentration of the sun's rays in this part of the surface, so that their temperature rises. This improves the installation efficiency. When this air supply is through opening 14, which angle increases It will be large, which reduces the resistance at the inlet. However, this decreases the effective height of the tube, which leads to lower power settings. The optimal value of the angle of inclination within ^30-45 o, when the input section further increase slightly affect the increase in efficiency and reduction in the effective height of the pipe is not significant.

In addition, for more effective use in the installation of insufficient sunlight hours of heating, especially at night, the unit may be supplemented placed at the bottom of the burner tube, which may further enhance the thrust in the pipe. Work additional elements explained in FIG. 3, which shows that when heated by the sunlight is insufficient to increase the air flow power (thrust) through the burner 18 can be supplied to the small amounts of fuel which is burning (flame shown at numeral 19) creates increased traction.

Thus, the proposed setup allows electric power to generate electricity by using the alternative energy sources, and thus can be used both in industry and for domestic use. It may be particularly useful to use it to supply customers located at a distance from the existing electrical networks, or as a backup power consumers.
