Description

"HYDROMOTIVE BOX"

The present invention refers to a "HYDROMOTIVE BOX", hydraulic device that, by the use of the atmospheric pressure, it is capable to move a turbine for electric power generation.

Between the forms of movement of turbines for generation of energy, it can be used the hydraulic power, tides power, wind power, thermal power, solar power, and others.

All those models are suppressing the human need, however, in the case of the hydraulic power, they are necessary the rivers and unevenness, in the tides, it is necessary proximity of the ocean, in the wind power, constant winds, in the solar, the radiation and the thermal is originating from fossil fuels, being pollutant, and that, one day, it will arrive to the exhaustion.

Exploring this concept, the hydromotive box aims at the electric power generation by the use of the atmospheric pressure.

The present invention has as objective increases an option for generation of clean energy, using beginnings not used currently for such, as the force of the gravity, the atmospheric pressure, the density difference between the air and the water and still the vacuum to keep certain volume of water in continuous movement, making possible the operation of a turbine for transformation of the hydro-mechanic energy in electric energy.

The "HYDROMOTIVE BOX" of the present invention is described as a main reservoir (1), in cubic, cylindrical, or in any polyhedral shape, done in metallic structure or any other non deformable material, tightly closed and totally sealed when closed, with opening with cover (2) for provisioning, totally sealed when closed, having other opening linked to a empty tube (3), in curve of 180° for entrance of water, touching its inferior part and perfectly welded to the main reservoir (1), or linked to this by process that allows total sealing, impeding the entrance of air, extending until the interior of the reservoir of return (7) of water; and an opening linked to a tube of water exit (4), in its inferior part, with register (5), leading a turbine or BWT (bomb working as turbine) (6), linked to the reservoir of return (7) of water, smaller than the main reservoir (1), with the superior border open, whose water level cannot be below 8 meters of the superior part of the main reservoir (1), and a piping inside this deposit immersed in water and linked to the entrance of water (3).

The "HYDROMOTIVE BOX" operation is based on beginnings of the physics and mechanic of fluids and it assists to the concepts and operations described in the sequence. The main reservoir (1) of the hydromotive box should be produced in metal totally sealed, besides the cover, when closed (2). With the register (5) closed, it becomes full the main reservoir (1) and the reservoir of return (7) of water, whose level of the water cannot be below 8 meters of the superior part of the main reservoir (1) to make possible the action of the atmospheric pressure. Once the reservoirs full, the register (5) is open to allow the passage of the water.

The water of the main reservoir (1), pressed by its weight, will drain by the exit piping (4), which will produce vacuum in the superior part of the main reservoir (1). Still when leaving the main reservoir (1), the water will pass by the turbine (6), moving it, and it will drain to the reservoir of return (7) of water, increasing the level of said reservoir of return (7).

The vacuum produced by the exit of water of the main reservoir (1) will be filled out, making possible the suction of the water contained in the reservoir of return (7), in function of the atmospheric pressure, through the piping (3) that links the main reservoir (1) to the reservoir of return (7), keeping it balanced. It is formed then a continuous movement of fall and ascension of water, which will make possible the continuous feed of the main reservoir (1), the circulation of water by the turbine (6), provoking its movement, the entrance in the reservoir of return (7) and the return by suction to the reservoir. To interrupt the process, it is enough to close the register (5). With the time, due to losses by evaporation, the level of water should be restored.

A variation of the "HYDROMOTIVE BOX" can be used for generation of energy in small climbs and in places where there is water abundantly. For such, it is just used the main reservoir (1), the up to 8 meters above the level of water, and a piping for suction of water. The inventor, still glimpsing an operational improvement in the hydromotive box above mentioned, has created a flotation main reservoir to increase the internal pressure in the main reservoir, and consequently in the exit piping and to optimize the flow of circulation of the water.

Of an illustrative way, a cylindrical reservoir with 100 m of height and basal diameter of 10 m, filled out with water, it presents in its base a pressure of 100 m of column of water, 10 atm or 103.300 Kg / m2. Passing the reservoir for a cylindrical shape, of same height, having in its superior portion an enlargement in half-sphere shape, with diameter of 50 m just like a cup, in spite of supporting larger volume of water, therefore more weight, due to the hydrostatic paradox, the pressure in its base will continue to be of a column of water of 100 m. Using the same structure in cup shape, supposing that in its superior part it was removed part of the volume of water, equivalent to a half-sphere of diameter of 40 m, in spite of the weight to decrease, the height is the same and, due to the fundamental theorem of the hydrostatic, the pressure in its base continues to be of a column of water of 100 m. Finally, if a half-sphere is put in an empty space, in any material, with enough density to float with its superior part, touching the level of water, by the Pascal beginning that the liquids transmit the pressure for equal in all the senses, said half-sphere passes its weight to the liquid that will be distributed by the area, being in this case the pressure in the bottom of the reservoir the resulting from the pressure of the column of 100 m of water added of the weight of the half- sphere divided by the internal area of the structure (bottom and laterals) that contains the water that supports said structure.

Mathematically, for the reservoir in cup shape with spherical superior part and cylindrical base with height of 100 m, diameter of the superior part of 50 m, diameter of the base of 10 m, diameter of the sphere of 40 m and density of the sphere of 0,99, it is obtained:

- Volume of the half-sphere = 16755,2 m3

- Weigh of the half-sphere = 16587,651

- Area of the interior of the structure = area of the half-sphere + area of the lateral of the cylinder + area of the base of the cylinder = 6361 ,74 m2 Being like this, the weight of the half-sphere when floating divided by the total internal area of the structure determines its pressure by m2 transmitted to the water that is equal to 2,61t.

The pressure above is transmitted to the whole liquid of the reservoir, being the pressure in the base the result of the pressure exercised by the column of water added the pressure exercised by the half-sphere resulting in 105,91 1 / m2. In that way, pressure can be added to the water to win the resistance of the atmospheric pressure, optimizing the operation of the hydromotive box by for action of the flotation device.

Obviously, the dimensions and shape of the reservoir, with smaller internal area and the shape of the main reservoir with larger volume, possible since compatible, will be calculated to overcome the pressure of the reservoir of return (7), added of the atmospheric pressure, obtaining like this the movement and/or continuous flow of the water.

In order to better elucidate the present addition, it is made reference to the enclosed drawing (Figure 5) that shows a lateral cut as a way of making possible the hydromotive box in half-spherical shape, whose shape reduces the attrition provoked by the curves.

The improved "HYDROMOTIVE BOX" refers to a flotation device (A) added to the water layer of the main reservoir (1), it could be in any shape, whose medium density is inferior to the one of the water, what makes possible its flotation, calculated in way to present the largest volume in a smaller area with the objective of adding pressure to the interior of the main reservoir (1). On the other hand, a valve (9), of only sense, was inserted ascendancy in the return piping (3) to allow better primer of the system. Basically, the device (8) should has conditions of balance, flotation and stability, capable of keeping it in the wanted position in the main reservoir (1) and allowing the circulation of the water in the system, in accordance with its configuration and weight dimensioned to overcome the pressure of the water in the reservoir of return (7), added of the atmospheric pressure, optimizing the performance of the hydromotive box. Another improvement made in the system proposes ways to increase the options for operation of the "HYDROMOTIVE BOX" by alteration of the space disposition of the reservoirs with the purpose of obtaining larger versatility and income, that, as it will be demonstrated, is susceptible to work without the atmospheric pressure and in an ideal combination with the atmospheric pressure only acting in the main reservoir (1), as well as under vacuum or under atmospheric pressure in the main reservoirs (1) and reservoir of return (7). In order to better understand this addition it is necessary to know about the behavior of a same liquid in communicating vases:

- communicating vases with liquid of same density, the surfaces free from the liquids are in a same horizontal plan. - communicating vases with liquids of different densities, when the balance settles down, a quota unevenness is generated inversely proportional to the densities of the liquids.

Therefore, in a liquid in balance, the pressures should be the same ones to count of the same horizontal plan. The "HYDROMOTIVE BOX" has the main reservoir (1) and the reservoir of return (7) united, in their inferior part, by an exit piping, characterizing a communicating vase with the same liquid (water). Theoretically, the liquid is balanced equaling its pressure in a same horizontal point; however, the flotation device included in the main reservoir (1) increases the internal pressure of said reservoir. Therefore to equal the pressure in two points horizontally aligned, one in the line of the reservoir of return (7) and other in the line of the main reservoir (1), and to obtain balance, the column of water of the reservoir of return (7) will be elevated until reach pressure equivalent to the internal pressure of the main reservoir (1). Consequently, the liquid is balanced equaling its pressure in a same horizontal plan, however the flotation device, included in the main reservoir (1), increases the internal pressure of the said reservoir.

Until then it was used the premise that the atmospheric pressure acting in the reservoir of return (7) elevates the column of water for the return piping. This is valid, but, according to the explained concept, it is enough the pressure exercised by the flotation device to elevate the column of water in the reservoir of return (7).

Such statement can be mathematically proven for the main reservoir (1) in semi-spherical shape with diameter of 100 m and height (stripe) of 50m. The flotation device has semi-sphere shape with diameter of 80 m and stripe or height of 40 m with density of 0,99 in relation to water (1t / m³). The exit piping is cylindrical with diameter of 10m and extension of 50m. Finally, the reservoir of return (7) is cylindrical with diameter of 10m. By the fundamental theorem of the hydrostatic, the difference of pressures, between two points any of a same liquid in balance are same to the weight of the liquid column that has as base the surface unit and as height the vertical distance between two points (A and A¹). Therefore the pressure will be calculated in the point A¹, superior point, aligned to A and that it receives the pressure of the column of water of the main reservoir.

Take a point A, located to 10mt above the bottom of the main reservoir; the pressure in A will be the height of the column of water in meters added of the pressure of the flotation device that acts in the internal area of the main reservoir (1) added to the internal area of the exit piping.

Being like this:

- Column of water on A - 40 m.c.a. or 4 atm (10.330 kgf/m²), or 41.320 kgf/m²; Weigh of the flotation device

D = M/V or 0,99t/m³ = M / 4 x? x 40³ / 6 or M = 132.701.18t Internal area of the main reservoir:

4?r²/2 or 4 x? x 50 x 50 / 2 = 15.708 m²

Internal area of the exit piping (4)

Area of the cylinder or πτ² + 2πτ x length or (π x 5 x 5) + (2 π x 5 x 50) = 1.649,34m²

Total of the area it internals made calculations 15.708m² + 1.649,34m² = 17.357,34m²

The pressure exercised by the flotation device will be its weight divided by the calculated area:

Pressure = 132.701, 18t / 17.357,34m² = 7,64t/m² or 7.640 kgf/m² The pressure in the point A is of 41.320 kgf/m² for the height of the column of water and it will be added by the pressure exercised by the flotation device, 7.640 kgf/m², the total pressure in the point A will be 48.960 kgf/m².

However, so that this system is balanced it should have the same pressure in the two vases, then the height of water in the reservoir of return (7) should be larger than the height of the water of the main reservoir, because it has in its interior the flotation device. This condition will be analyzed in the next 4 cases:

- Case 1 : the main reservoir (1) is closed to vacuum and the reservoir of return (7) under atmospheric pressure. The column should be elevated 48,96 m above the point A', but the atmospheric pressure of 10.330 kgf/m² acts reducing its height and stabilizing it in 38,63m, in this case the total height of the level of water of the reservoir of return (7) will be of 48,63m (1 ,37m below the level of water of the main reservoir) once the point A is 10m above the inferior level of the water, this height of the column is enough to keep the "Hydromotive Box" operation, because the atmospheric pressure will elevate the water by the return piping, making it to return to the main reservoir (!). - Case 2: the main reservoir (1) is under atmospheric pressure just like the reservoir of return (7). The internal pressure of the column of water and of the flotation device added of the atmospheric pressure will result in a pressure of 59.290 kgf/m² above the point A and the column of water in the reservoir of return (7) will be of 48,96m above the point A', passing in 8,96m the height of the main reservoir (1), it will be added of the atmospheric pressure, resulting in a total pressure equal to 59.290 kgf/m². - Case 3: both reservoirs are closed to vacuum.

The pressure in the main reservoir (1) above the point A will be of 48.960kgf/m² and in the reservoir of return (7), to keep the balance it will be same, or 48,96 m, also passing in 8,96m the height of the main reservoir (1), as in the previous case. - Case 4: the main reservoir (1) is under atmospheric pressure and the reservoir of return (7) is closed to vacuum.

The internal pressure of the column of water and of the flotation device added of the atmospheric pressure will result in a pressure of 59.290 kgf/m², to keep the balance the column of water in the reservoir of return (7) will be of 59,29m above the point A', passing in 19,29m the height of the main reservoir (1).

In order to better elucidate the present addition, it is made reference to the enclosed drawings (Figures 6 to 12).

The "HYDROMOTIVE BOX" of this improvement refers to a hydromotive box (C) composed of a main reservoir (1) of semi-spherical shape, united by piping (4) of exit to the reservoir of return (7). The flotation device (9), equally semi-hysterical, increases the internal pressure in the main reservoir (1), and to equal the pressure in the points (A and A') with the same quotas (h and h¹), and to obtain the balance of the liquid, the column of water in the reservoir of return (7) will rise (H') until reaching the pressure equivalent to the internal pressure of the main reservoir (1) of level (H), as demonstrated in the figure 6.

The figure 7 demonstrates the operation of the hydromotive box (C) with the main reservoir (1) closed with cover (2) to vacuum and the reservoir of return (7) under atmospheric pressure (PA).

The figure 8 demonstrates the operation of the hydromotive box (C) with the main reservoir (1) subject to the atmospheric pressure (PA) just like the reservoir of return (7). The figure 9 demonstrates the operation of the hydromotive box (C) with the main reservoir (1) open, as well as the reservoir of return (7) to vacuum.

The figure 10 shows the hydromotive box (C) worked under atmospheric pressure in the reservoirs (1 and 7) with option of putting a turbine (6) in the return piping (3) subsequent to the register (5). The figure 11 shows the hydromotive box (C) worked with the reservoirs (1 and 7) with option of putting a turbine (6) in the return piping (3) subsequent to the register (5).

The figure 12 shows the hydromotive box (C) worked with the main reservoir (1) open and the reservoir of return (7) closed to vacuum with cover (2), with option of putting a turbine (6) in the return piping (3) subsequent to the register (5), in that case the exit of water should be under positive pressure.
