Definitions
- the present invention concerns a hydro-pneumatic mechanic device for the exploitation of the wave motion for obtaining renewable and ecological energy.
- the present invention comprises a series of six submerged cylinders, placed on wharfs fixed to the ground, on floating pontoons or on structures which allow the immersion thereof at a depth necessary for optimizing the efficiency of the system, according to the intensity of the wave motion, provided, in their lower part, with a conical opening for the water inlet and, in their upper part, with conical, spherical or plain shapes with lateral openings, respectively for producing compressed air, pumping water or generating mechanic energy.
- the advantages of the device according to the present invention consist in the minimal environmental impact, in obtaining renewable energy and in the simplicity of said structures.
- Figure 1 shows a variant of the hydro-penumatic mechanic device for the exploitation of the wave motion according to the present invention, comprising a spherical head for the production of compressed air.
- Figure 2 shows a front view of the device according to the present invention.
- Figure 3 shows the device according to above mentioned variant, comprising a reservoir 9 for the collection of the air, and mounted on a wharf 10, fixed to the ground, floating or at controlled immersion.
- Figure 4 shows a variant with a conical head for the production of compressed air
- figure 5 shows a front view of the device according to the present invention.
- FIG. 6 shows the device according to the variant shown in figures
- Figure 7 shows a variant with a conical head for pumping water into collection basins or reservoirs, while figure 8 shows a front view.
- said variant shown in figures 7 and 8 comprises the reservoir 9 for the water collection, mounted onto a floating wharf 10.
- Figure 10 shows an embodiment of the device for the production of compressed air.
- Figures 11, 12 and 13 show a variant of the device for the transformation of the wave motion into mechanical energy.
- Figures 14, 15, 16 and 17 show the four main phases of the cylinders forming the system.
- Figure 18 shows the shock-absorbing means of a possible floating piston 20, in case of release and compression.
- Figure 19 shows a lateral section and axonometric and transparency view of the detail of the end of stroke system of a transmission shaft.
- Figure 20 shows a front, lateral and axonometric view of the system that collects the motion of the distribution rods for transferring the motion to the differential.
- Figure 21 shows a lateral view of a variant with a plain head for the production of compressed air
- figure 22 shows the shape of the floating pistons for the working of said plain head.
- the enclosed figures show a hydro-pneumatic mechanic device for the exploitation of the wave motion according to the present invention for obtaining renewable and ecological energy, comprising:
- a sluice-gate hand operated, for closing the passage of the air from the cylinder to the collection and distribution system, so as to be able to act in case of servicing;
- the working of the hydro-pneumatic mechanic device for the exploitation of the wave motion for obtaining renewable and ecological energy may be described as follows: - the water entering said cylinder 5 due to the wave motion from the inlet cone 6, pushes said piston 7 towards the spherical head of said cylinder so that the air inside will get compressed towards the outlet of said cylinder, opening the unidirectional valve 4 and transferring the air towards the collection and distribution system; when the wave lowers, the piston is called back downwards and said valve 4 closes, thus preventing the outlet of the collected air, and valves 3 open favouring the inlet of fresh air cleaned by filters 2, inside said cylinder, the sealing whereof is guaranteed by said bands 8 on the piston.
- said cylinder is completely submerged in the water so as to exploit at the maximum the compression and decompression action determined by the wave motion inside the same, and the pressure of the wave opens said unidirectional valve 4 transferring the water towards the collection basin or reservoir; when the wave lowers, the depression closes said valve 4 avoiding the outlet of the collected water, and valves 3 open favouring the inlet of fresh water inside said cylinder and reducing the previously generated pressure.
- the reservoirs are placed below the sea level and they are filled due to the phenomenon of the communicating vessels, using underground pipes provided with filters F for avoiding the inlet of deposits and impurities.
- the compressed air produced by one of the hydro-pneumatic mechanic systems according to the present invention, will be let in, for sending the water to the electric turbines; the air let in said reservoirs 13 creates the pressure necessary for the outlet of the water through a pipe that will serve the users or the electric turbines; when the water level is near to nul, the level gauge 14 inside the reservoir sends a signal to an electronic panel 15 for the control of the closing of the valve 16 of the water for the users and of the valve 17 for the inlet of compressed air; in the same time it opens valves 16 and valve 17 for the inlet of compressed air in the next reservoir.
- the central panel While the reservoir is working, the central panel will contemporarily open the exhaust valve 18 and valve 19 for filling said reservoir 13; when the latter is filled again, the level gauge 14 will send a new closing signal to said valves 16 and 17.
- this variant comprising two reservoirs 13, and adjusting the opening diameter for the water inlet and outlet, a continuous cycle for the water distribution is obtained, emptying one reservoir while filling the other. If a greater flow to the users is needed, the present invention provides a plurality of reservoirs.
- the floating piston 20, shown in detail in figure 18, further comprises:
- shock absorbing system 38 - a shock absorbing system 38; - a ring 39 for sealing the shock absorbing system.
- This variant comprises a series of cylinders; when the wave passes, the water enters the cylinder from the inlet cone 6 and receives such a pressure as to push upwards said piston 20 connected to a toothed rod 21 which operates gears 24; when the wave lowers, it creates a depression such as to suck the piston downwards; in its descending phase, the toothed rod 21 operates said gear 25.
- the device according to the present invention consists of a plurality of cylinders and allows to the transmission of the differential a continuous motion.
- the device according to the present invention collects any wave motion; in case of rough sea, the cylinder has been provided with openings 26 for the water exhaust which will get open when the shock absorbing system 35 on the head 36 of the piston gets squeezed.
- a system is also provided for absorbing heavy pushes and opening the water discharge openings 26 and, when the wave lowers again, pushing said piston 20 downwards for closing said openings so that he depression inside the cylinder drags the piston on the ground with force.
- a end of stroke system shown in figure 19, is provided for avoiding the outlet of the shaft-piston 21-21, provided with a shock absorbing element for attenuating the blow. Furthermore, the inlet cone 6 will allow the passage of the air, annulling the depression created by the descending wave, as shown in figure 17.
- the variant with plain head shown in figure 21 for the production of compressed air has a greater number of unidirectional valves 3: this solution may be applied also to the preceding variants for easing the inlet of air or water into the cylinder and increasing the total efficiency of the system;
- said cylinder houses a floating piston 40 with cylindrical shape, shown in a lateral scheme in figure 22, provided with sealing bands 41 and with a special flexible gasket 42, fixed to the top of said piston by means of a blocking plate 43 provided with screw bolts 44, so as to prevent the formation inside said cylinder 5 of air pockets that might reduce the efficiency of he system.
- the water entering inside said cylinder 5 through said inlet cone 6 due to the wave motion pushes the piston 40 upwards compressing, by means of the action of the flexible gasket 42 of said piston 40, all of the air present in the cylinder towards the plain head of the same, thus preventing the forming of air bags inside until the opening of the unidirectional valve 4 is obtained, for transferring the air towards the special collection and distribution system.
- said piston 40 When the wave lowers, said piston 40 is recalled downwards, being favoured in the movement by the flexibility of said gasket 42, causing the closing of said unidirectional valve 4 and the contemporary opening of said valves 3 for the inlet of fresh air cleaned by special filters 2 inside said cylinder 5, the sealing whereof is assured by bands 41 provided on said floating cylinder 40.
