Possible construction of the invention
The solar thermodynamic power station consists of a power generator 15, with a turbine 16, coaxially mounted to it, which is propelled by the air flow, heated on a plurality of fire-proof black bodies by the heat of the sun; the black bodies are mounted on a base and covered by a transparent lid.
The fire-proof bodies represent base profile plates 2, disposed one above the other, having loops 5, and additional profile plates 3, having loops 5, which, along with the transparent lid and the base, form the separate module 9. The top surfaces of the base profile plates 2 and the additional profile plates 3 are covered in black. There may be more than one module 9, which are to be mounted in series, forming a tunnel and should be on a slope with a certain grade, using the loops in the four ends of the transparent lid 1 , which is actually a glass semi- cylinder. In such a case the incoming opening for the air flow is situated lower in comparison to the outgoing opening.
The turbine 16 is disposed at the outgoing opening of the module 9 and the generator 15 is mounted coaxially.
At the entrance of module 9 there is an aerodynamic incoming device 6, and an outgoing propelling device 20 is mounted at the outlet of the turbine. The turbine 16 is enclosed into a thermo-insulating blanket 17, while the generator 15, using disk brakes 14, is disposed below it and out of the blanket 17.
The base profile plates 2 may be made of copper and the additional profile plates 3 - of cast iron. The base is in the form of a rectangular insulating plate 4 and the transparent lid 1 is a semi-cylinder empty glass body.
The aerodynamic incoming device 6 consists of a large 8 and a small 7 stabilising profile with aerodynamic form. They are made of profile blocks of fire-proof material and black cover, mounted on a thermo-insulating plate 4; the support steel profiles 10 are mounted between them. The cover structure 13 is mounted on the support steel profiles 10; it also has an aerodynamic profile and is black on top. A glass lid 12 is mounted on it, with a superstructure 11, used to reduce the load on the glass lid 12.
The outgoing propelling device 20 consists of a lower movable part 21 , containing a bearing body 19 and an upper part 22 with vertical walls, forming the stabilising plates 23, used to direct the wind flow according to its blast.
There are maintenance shop rooms 24 to facilitate the maintenance of the generator and the turbine.
Application of the invention
The solar thermodynamic power station may be constructed of prefabricated components on prepared sites on slopes, hills and mountains with a slope grade of 20-60
degrees, oriented from southeast to southwest. The greater the difference between the incoming and the outgoing devices, the higher capacity of the system.
After a sloped site is selected and prepared, steps and rail beds shall be mounted, along which a servicing platform with a mini-crane will move. Then the insulation plates 4 shall be mounted on the slope, using foundation bolts. Cast iron profile plates 3 and copper profile plates 2 shall be placed on the insulating plates 4, and on top a glass lid 1 is mounted, using loops 5 and foundation bolts to fasten it to the slope; those are later set in concrete. Thus module 9 is formed, and several modules may be mounted in a series to form glass tunnels.
On the periphery of the profile of the glass semi-cylinder, at its both ends, a metal strap is inlaid reaching the loops 5, similar to those on the profile plate 3. These are used to fasten the whole structure to the ground.
The next element is represented by the cast iron plates 3, two in each semi-cylinder, identical in size and configuration; they are mounted with allowance for the thermal expansion of the metal. The copper profile plate 2 shall be set on them, the lower end needs to be ground for tighter fit to the cast iron profiles 3, whose contact surfaces shall be ground, too. The clearance between the glass semi-cylinder 1 and the cast iron plates 3, resulting from the thermal expansion and contraction of the metal plates 3, shall be taken care of by heat-resistant rubber seals. The sunlit surfaces shall be painted in black by the electrostatic method for better heat absorption. Thus the glass semi-cylinder 1 and the heating profile plates 2 and 3 are ready for usage. As an alternative, the copper profile plates 2 and the cast iron profile plates 3 may be replaced by fire-proof material plates in the same form and also painted black for better heating.
As the small and the large stabilising profiles 7 and 8 have aerodynamic form, this helps the laminar air flow and increases the speed of the incoming flow of air. In rainy weather, the dynamic airflows will bring in some water, too, but it will be specially drained out.
Next is the construction of the maintenance shop rooms 25, of concrete, in two storeys, the first floor containing the generator 15 moved by the hot air turbine 16. Turbine 16 shall be serviced form the second floor, after the disk breaks 14 stop it. It is centred by a double axial bearing 19. The outgoing device 20 is mounted on top of the blanket 17 of the turbine 16. it is made of aluminium through casting, containing a lower part 21 , en extension of the blanket fixed to the upper axial bearing 19. The upper part 22 of the outgoing device is formed in a way so that the vertical walls my form the stabilising plates 23, which orientate it according to the direction of the wind blast.
After the air flow passes through the incoming device 6 it is heated by the small and the large stabilising profiles 7 and 8, the temperature of them both and of the incoming air rises, the air moving up the profiles 7 and 8 and into the incoming device 6. The reinforcing steel profiles 10 are also heated, and they themselves add heat the air flow and stabilise it. The air thus heated flows over the lower end of the metal cover structure 13 with an inverted aerodynamic
profile, painted in black on the outside and covered by the glass lid 12 to save the temperature. This system of profiles and the covering structure 13 comprise the incoming aerodynamic device 6, which heats up the air and gives it a high initial speed even before it enters the glass semi-cylinders 1. Then the air moves to the central part of the incoming device 6, where its is sucked in by the first module of the glass semi-cylinder 1 and goes up along the glass tunnel, continuously heated and speeded up till it enters the turbine 16. Each module is made of glass semi-cylinders 1 with a specific length, the first and last ones might differ in length for construction purposes. The copper profile plate 2 has longitudal channels, which do not hamper or swirl the air flow but heat it optimally. The air flow is heated on the copper 2 and cast iron profile plates 3, themselves heated by the sun, and the heat and the speed of the air rise till it flows into the turbine 16, connected to the generator 15, having disk breaks 14 for emergency stops and prophylactics.
The outgoing device 20 is situated above the turbine 16, letting the hot air in the atmosphere but not letting the speed of the turbine fall down, which otherwise will result in lower efficiency.
The outgoing device 20 may rotate along with the wind, following the direction of its blast all the time. In this way the wind, flowing around the outgoing device 20, sucks out the hot air from the turbine, facilitating its operation and raising the efficiency of the system.
When the sun sets, the power station shall continue its performance, due to the heated profile plates 2 and 3 in the glass tunnels, till they cool down completely. During the night the system will use the natural atmospheric circulations and in case of its absence, it will operate due to the temperature differences at the incoming device 6 and at the outgoing device 20, i.e. completely cool.
