[014] The following detailed description of embodiments of the invention refers to the accompanying drawings referred to above. Dimensions of components and features shown in the figures are chosen for convenience or clarity of presentation and are not necessarily shown to scale. Wherever possible, the same reference numbers will be used throughout the drawings and the following description to refer to the same and like parts.
DESCRIPTION OF EMBODIMENTS OF THE INVENTION
[015] Illustrative embodiments of the invention are described below. In the interest of clarity, not all features/components of an actual implementation are necessarily described.
[016] Fig. 1 shows an apparatus for converting ocean wave energy to another form of energy, according to embodiments of the invention. The apparatus includes an energy receiving portion 10; and an energy storage and conversion portion 12.
[017] Energy receiving portion 10 includes a buoy or float 14 adapted and arranged to move in reaction to the movement of ocean waves; and a float frame 16 to which float 14 is attached. Energy receiving portion 10 also includes a piston 18 which is pivotably connected to frame 16 via a first pivotable connection 20 at a first end of the piston; and a fixed structural wall 22 to which a second pivotable connection 24 is attached at a second end of the piston.
Frame 16 is also pivotably connected to structural wall 22 via a pivotable connection 26. The movement of float 14 upon the waves compresses and retracts piston 18 thereby producing hydraulic fluid pressure which can be used to produce useful energy in energy storage and conversion portion 12, which will now be described. The hydraulic fluid typically used is oil, and will be used hereinafter in the claims to denote any suitable hydraulic fluid.
[018] Energy storage and conversion portion 12 includes one or more pressure accumulators 30 (three shown), which receive the pressurized oil from piston 18 flowing in a pipe section 32, which has a one-way valve 34, thereby preventing the pressurized oil from going back to the piston. Pressure is maintained in accumulators 30 by a gas disposed above the oil that is accumulated in the accumulators. Portion 12 also includes a piping system as shown in Fig. 1 and described below.
[019] Pressurized oil from accumulators 30 is then fed to via a pipe section 36 to a hydraulic engine or motor 38 enabling the conversion of the oil pressure (flow) into rotational motion, which can be converted into electricity by an alternator 39. The electric energy can then be used to operate a water desalination unit or other equipment, etc. Pipe section 36 includes a flow valve 40 allowing for control of oil flow from pressure accumulators 30 to motor 38.
[020] Energy storage and conversion portion 12 further includes a hydraulic oil tank 42 where excess oil may be stored and useful for charging the pipes with oil. Downstream of oil tank 42, is a one-way valve 44. Pipe section 36 typically further includes a one-way valve 46 in pipe section 36, a pressure regulating valve 48 and a pressure relief valve 50.
[021] In sortie embodiments, the apparatus further includes a recycle pipe 51 with a one-way valve 52, which can be useful for protecting motor 38 in the event that the oil pressure drops suddenly. Recycle pipe 51 will continuously bring low pressure oil into motor 38. For such purpose, at or downstream of accumulators 30 is a pressure gage 53 for monitoring the oil pressure, whcih can be operably connected to one-way valve 52, and which in some embodiments is thus usable to automatically control recycle flow. In some embodiments, the apparatus further includes a bypass 54 to deal with excess pressure in accumulators 30 whereby a portion of the pressurized oil will be directed toward oil tank 42.
[022] Accumulators 30 have a gas-filled upper portion 55 and an oil-filled lower portion 56 separated by a diaphragm 57. Gas-filled upper portion 55 is charged with gas at high pressure to maintain, or increase, the oil pressure in oil-fill lower portion 56.
is [023] Pistons 18 receive oil returning via hydraulic oil tank 42, thus creating a circular oil flow. The oil is pressurized by piston 18 and flows into accumulators 30. Downstream of accumulators 30, the oil flows to motor 38 where the energy of the pressurized oil is converted to rotational mechanical energy. Via alternator 39, electrical energy can be produced.
[024] The aforementioned valves disposed in the aforementioned piping system, allows oil flow in the direction needed to achieve the desired effect.
[025] In some scenarios, float 14 is filled with air, in order to maximize efficiency of ocean wave energy or the float is filled with water, in order to protect the apparatus in case of high tides or storm. Intermediate situations between the above two extremes are possible, wherein float 14 is partially filled with water; and, in some embodiments, float 14 includes internal compartments or an array of internal floats (not shown). In some scenarios, the apparatus includes a pluraiity of floats 14.
[026] Figs. 3-6 show particular features of float 14. Float 14 has top 60, connected to frame 16; and bottom 62; a front face 64 facing incoming waves; a rear face 66 via which the water from those waves flow back toward the ocean/sea; and sides 68. Front face 64 has an angled lower front surface 70 protruding frontward at an angle Al with respect to bottom 62 of float 14. In some embodiments angle Al is 135 degrees +1-10 degrees, whereby angled lower front surface 70 of front face 64 forms an angle of 45 +1-10 degrees with respect to horizontal (i.e. the calm surface of the ocean) -presuming that float 14 is attached to wall 22 whereby float 14 is generally horizontal.
[027] Similarly, front face 64 has an angled upper front surface 72 sloping at an angle A2 with respect to top 60 of float 14. In some embodiments, angle A2 is 135 +1-10 degrees, whereby upper front surface 72 forms an angle of 45 +1-10 degrees with respect to horizontal -presuming that float 14 is attached to wall 22 whereby the float is generally horizontal.
[028] Angled lower and upper front surfaces 70 and 72 of front face 64 meet at a curved or rounded front surface 74, which is typically located between is about 60% and 80% up from bottom 62; i.e. the rounded front surface is closer to top 60 of float 14 than to the bottom of the float. As such, front face 64 has a rounded conical profile somewhat similar to the profile of a nose cone of a typical commercial passenger airplane.
[029] Rear face 66 has an angle A3 with respect to bottom 62 of float 14. In some embodiments, angle A3 is 45 +1-10 degrees. Thus, in such embodiments, rear face 66 is generally also angled 45 +/-10 degrees with respect to water receding back to the ocean -again, presuming that float 14 is attached to wall 22 whereby the float is generally horizontal.
[030] The particular configuration of front face 64 allows for incoming waves to raise float 14 without undue instability (shaking, rattling, twisting force) as well as for a portion of large waves to pass over the float. In effect, the aforementioned configuration facilitates a dissipation of the horizontally directed energy of the waves, which could otherwise cause mechanical stress to float 14 and the remainder of the apparatus. The particular configuration of rear face 66 allows for water receding back into the ocean to do so without undue stress on float 14 and the remainder of the apparatus.
[031] As best illustrated in Fig. 6, in some embodiments, sides 68 of float 14 are angled, forming angles A4 with respect to bottoms 62. In some modifications, angles A4 are 45 +1-10 degrees. Such angled sides 68 can also be useful for facilitating a relatively calm wave flow by float 14 thereby reducing stress on the float and the remainder of the apparatus.
[032] It should be understood that the above description is merely exemplary and that there are various embodiments of the present invention that may be devised, mutatis mutandis, and that the features described in the above-described embodiments, and those not described herein, may be used separately or in any suitable combination; and the invention can be devised in accordance with embodiments not necessarily described above.
