Definitions

  • the present invention relates to a fluidic recovery device for recovering kinetic energy, e.g. of a moving motor vehicle or train.
  • the kinetic energy of a motor vehicle is converted to potential energy of a fluid, which can thus be used to power a hydraulic turbine connected to an alternator to produce clean, alternative electric energy of zero environmental impact.
  • wind and photovoltaic energy systems can only be used over a relatively small part of the day, and in given geographical areas.
  • Figure 1 shows a view in perspective, with parts removed for clarity, of a kinetic energy recovery device in accordance with the present invention
  • Figure 2 shows a partial section along line II-II in Figure 1;
  • Figure 3 shows a view in perspective of a further embodiment of the present invention
  • Figure 4 shows a partial section along line IV-IV in Figure 3;
  • Figure 5 shows a partial section along line V-V in Figure 4.
  • Number 30 in Figure 1 indicates as a whole a modular fluidic kinetic energy recovery device comprising a number of superimposed plates 1, 2, 3, 4 of different thicknesses, and which are made of any metal or composite material capable of withstanding the loads and/or wear to which device 30 is subjected.
  • Figure 2 shows one of the pumping assemblies enclosed in plates 1, 2, 3, 4. More specifically, the pumping assembly comprises a pestle-shaped actuating member 5 movable back and forth to pump a fluid to a hydraulic turbine; a membrane 10 operated by actuating member 5; and a cavity 11 beneath membrane 10 and defining, with membrane 10, a variable-volume chamber.
  • Actuating member 5 comprises a hemispherical cap 53; and a projection 59 extending from the base of hemispherical cap 53 and positioned contacting membrane 10.
  • Device 30 also comprises one-way valves 13 connected fluidically to cavity 11; 0-rings 12 interposed between the plates to define respective fluidtight seals; bolts 6 to pack plates 1, 2, 3, 4 tightly together; and a cover membrane 8 on top of actuating member 5. More specifically, plate 2 integrally defines cavity 11; and plate 1 integrally defines, within its thickness, a corresponding through seat 9 for guiding in a slidable way the actuating member 5.
  • Membrane 10 is interposed between cavity 11 and through seat 9, and has a peripheral edge 60 compressed between plates 1 and 2, when bolts 6 are tightened, to define a fixed fluidtight connection.
  • Through seat 9 has an opening 51 adjacent to membrane 10, and an opening 52 opposite opening 51 in a direction perpendicular to membrane 10.
  • Actuating member 5 is inserted inside through seat 9 through opening 51, and cap 53 projects partly from plate 1 and is connected to cover membrane 8. Opening 52 and cavity 11 are smaller in diameter than cap 53, so that the sliding movement of actuating member 5 is limited by plate 1 on one side and by the bottom of through seat 9 on the other.
  • Cover membrane 8 is bolted to cap 53, and may be made of metal, possibly coated with polymer material to ensure suitable friction with the tyres, or of any material suitable for the purpose.
  • Actuating member 5 may be made of metal, polyurethane, polymer material, or any suitably rigid material. Cavity 11 and seat 9 may be cast, pressed, or machined.
  • Each cavity 11 corresponds with two one-way valves 13 housed in plate 3 and isolated by 0-rings 12, which define a seal towards cavity 11 and towards a header defined in plate 4 connected to plate 3 on the opposite side to plate 2.
  • plate 4 defines milled or stamped channels 14 connected fluidically to one-way valves 13 to define an intake circuit 7a and a delivery circuit 7b.
  • the pump assemblies mounted in plates 1, 2, 3, 4 are connected parallel by channels 14 in plate 4.
  • the recovery device 40 in Figures 3 and 4 is similar to device 30, and comprises superimposed plates 16, 17, 18, 19; elongated, bar-shaped, circular-section actuating members 15; and membranes 27 connected between plates 17 and 16, like membranes 10, and slightly longer than actuating member 15.
  • Top plate 16 defines seats 54 similar to seat 9 but elongated in shape to house respective actuating members 15.
  • Seats 54 are appropriately milled, and each define openings 55, 56, similar to respective openings 51, 52, by which to insert actuating member 15 inside through seat 54, and to define a limit stop preventing upward withdrawal of actuating member 15.
  • Plate 17 defines cavities 26 functionally similar to cavity 11 and elongated in shape to cooperate with respective actuating members 15; and, in the Figure 4 section plane, each cavity 26 and relative actuating member 15 have respective complementary arc-shaped contours.
  • each cavity 26 has respective holes 57 and 58, which communicate with respective non-return valves 25, one an intake valve and the other a delivery valve.
  • Cover membrane 8 comprises reinforcing plates 22 on top of the back of actuating members 15. Valves 25 are housed in seats formed in plate 18; and plate 19 defines a header connecting cavities 26 in parallel beneath valves 25. More specifically, plate 19 defines a first channel 20a connecting all the intake valves 25, and a second channel 20b ( Figure 5) connecting all the delivery valves 25.
  • Membranes 10, 27 may be made of any strong elastic material suitable for the purpose, such as polyurethane elastomers of 40 to 90 Shore A hardness or other hardness. Alternatively, best performance, efficiency, and strength are achieved using membranes 10, 27 formed by stamping shape-memory alloy sheet with nickel titanium or so-called superelastic alloys, or using ordinary spring steel sheet. Bar-shaped actuating members 15 are made of polymer materials of over 70 Shore D hardness.
  • Devices 30, 40 described above constitute individual modules, which may be laid in two lines along more or less extensive portions of highway, and may be connected to other identical modules to form an extensive system.
  • each module has fast-fit connections for connecting the headers defined by each plate 4, 19.
  • the intake and delivery circuits are connected in series, and the delivery circuits are equipped with instruments for controlling pressure and flow to the hydraulic turbine employing the pressurized fluid to generate electric energy.
  • the fluid used is water with additives to prevent oxidation, or a water and oil emulsion.
  • the ideal size of each module is 60x60 cm, and the modules may be laid in two lines along a highway, with a centre distance of 180 cm, or across the whole or part of the highway.
  • device 30 is preferably bolted to a support or frame (not shown) embedded in the road surface, flush with the blacktop on which passing vehicles travel, and can be dismantled and replaced easily.
  • Cover membrane 8 is aligned with the road surface, and is activated by a vehicle travelling over device 30.
  • cover membrane 8 assumes the curvature produced by the tyre rolling over it, and pushes actuating member 5 down until it, the cover membrane, comes to rest on plate 1.
  • Membrane 10 is thus deformed, the volume of the chamber is reduced, and the fluid inside the chamber is compressed and fed to delivery circuit 7b via non-return valve 13.
  • membrane 10 returns to a substantially flat configuration, draws another load of fluid into cavity 11, and keeps actuating member 5 in a rest position pending passage of the next vehicle.
  • Device 40 operates in the same way as device 30. Moreover, cavities 26 are oriented in the vehicle travelling direction, and, with reference to the same direction indicated by arrow F in Figure 3, delivery valves 25 are located at end 28, so that cavities 26 are exhausted gradually by a passing vehicle.
  • Devices 30, 40 may be employed as described above, or may have no cover membrane 8 and be embedded in the ballast of a railway line, preferably underneath and contacting the sleepers, so as to convert to energy the oscillation produced by a passing train. Devices 30, 40 may be even be used in pedestrian pavements.
  • the advantages of recovery devices 30, 40 are as follows .
  • a plate structure also provides for easily accommodating all the component parts, and for extremely low-cost sealing using O-rings 12; and cover membrane 8 prevents dirt entering through seats 9 and so jamming actuating members 5, 15.
  • device 40 is simpler and comprises fewer component parts, while at the same time increasing fluid flow, thus ensuring better pumping action in all operating conditions, even in the event of passing vehicles braking or travelling at high speed.
  • Cavities 11, 26 and membranes 10, 27 may be formed in various ways, and membranes 10 and 27 may even be glued to or simply compressed between plates 1, 2 and 16, 17 respectively.
