Definitions

  • This invention relates to the field of devices which utilize the energy generated by waves on a body of water to drive a machine, such as an electrical generator to generate electricity.
  • waves may rise to a certain height within a given time, and the following wave may do the same. However, the next wave may rise substantially higher and within a shorter period of time, or it may do the opposite. Furthermore, waves may be of different lengths as well as heights.
  • Conventional driving mechanisms known to the prior art have a difficult time in making full and efficient use of the inherent energy in the waves of a body of water be ⁇ cause they are designed for a more or less uniform and predictable power source, such as the precisely timed firing of internal combustion engines.
  • a piston driven crankshaft of the type used in internal combustion engines would not work well if at all if the power source were ' waves on a body of water. Floats could be substituted for
  • one wave may be pushing upwardly against one float (piston) to apply power stroke force to the crankshaft at the same time another wave, unpredictably is also pushing upwardly against a second float (piston) which is in position rela ⁇ tive to the crankshaft for a return stroke.
  • the forces against the two floats (pistons) would cancel each other out preventing the crankshaft from turning at all.
  • each rack and pinion drive assembly mounted along the rotatable shaft provides a completely independent power stroke to the drive shaft regardless of what any of the other drive assemblies are doing, if anything at all, and furthermore each drive assembly provides such power stroke to the drive shaft in both directions, upwardly by the force of the wave against the float and downwardly by the force of gravity provided by the weight of the drive assembly.
  • a wave driven generator in accordance with this invention had say twenty rack and pinion drive assem- blies engaging twenty pairs of ratchet sprockets spaced apart along the rotatable drive shaft, and say an unpre- dictably long wave came along to force all twenty drive assemblies upwardly at the same time, they would each make full utilization of the full force of such wave in apply ⁇ ing full power to rotate the drive shaft in the same direction of rotation.
  • the drive assemblies of the present inven ⁇ tion do not have to move any given distance to complete a power cycle as for example a piston drive crankshaft of an internal combustion engine must do. If the seas are relatively calm and the waves small, the drive assemblies will be moved upwardly and downwardly relatively small distances. Yet they will transmit power of the wave on the up-stroke and of gravity on the down-stroke to the drive shaft, to substantially the same percentage when the waves and distance moved is small as when the waves and distance moved is large.
  • Turbine drives have also been attempted in .efforts to harness the energy generated by waves on open bodies of water. Turbines have some advantages over prior art crankshaft drives powered by reciprocating piston rods, in that turbines do not have to be precisely timed. How ⁇ ever, a turbine whose vanes are designed to deliver maxi ⁇ mum driving force or torque upon application thereto of a rapidly moving large volume of fluid will be very inefficient and deliver only minimum driving force or torque when a slowly moving or small volume of fluid is applied. Again, as pointed out above, the surface action of waves is unpredictable and random, as is the volume of water which may be delivered to any generating device positioned at or above water level.
  • the generator in accordance with the present invention overcomes the disadvantages inherent in reciprocally driven crankshafts of the prior art type, such as used in internal combustion engines, and of turbines known to the prior art, in that uniform and maximum force can be transmitted from wave action whether rapid or slow, large volume or small, to continuously rotate a drive shaft by use of a generator which incorporates the invention described in this specification.
  • It is an object of the invention to provide a wave driven generator including an elongated drive shaft for rotation in one direction, a plurality of reciprocating drive assemblies mounted along said shaft at spaced apart intervals, said reciprocating drive assemblies being in surface contact with the waves of a body of water on which said wave driven generator is positioned, said re ⁇ ciprocating drive assemblies being able to drive said rotatable drive shaft in said one direction of rotation by movement of said drive assemblies in both directions of reciprocation and independently of each other.
  • Fig. 1 is a side elevation view of a wave driven gene- rator in accordance with this invention, with one side wall of the mounting enclosure removed.
  • Fig. 2 is an enlarged side elevation view of one of the reciprocating double rack and pinion, ratcheted driving assemblies of this invention.
  • Fig. 3 is a side elevation view of one of the ratchet sprockets in accordance with this invention.
  • Fig. 4 is a section view taken on line 4-4 of Fig. 2.
  • Fig. 5 is a section view taken on line 5-5 of Fig. 4.
  • Fig. 6 is a perspective view of the wave driven gene- rator in accordance with this invention shown in operation on an open body of water, the walls of the enclosure shown as transparent for purposes of illustration.
  • a wave driven rotary motion generator 1 includes an elongated rotary drive shaf 2, supported at one end in journal bearing 3 which is secured to end wall 4 of an enclosure 5. The other end of the drive shaft 2 is con ⁇ nected through appropriate connecting devices to an electrical generator 6 which is mounted on end wall 7 of the enclosure 5.
  • the wave driven rotary motion generator in accordance with this invention may be con ⁇ nected directly to any type of machine having a rotary drive to provide the power to operate such machine.
  • the rotary motion generator is shown and described as driving an electrical generator.
  • a plurality of ratchet sprocket wheels 8 are mounted in closely spaced apart pairs or set of two or more, designated 8a and 8b in the case of pairs of closely spaced sprocket wheels, and designated 8a, 8b and 8c in the case of a set of three closely spaced sprocket wheels as shown in Fig. 1.
  • the ratchet sprocket wheels 8 include an annular body portion 9, teeth 10 projecting outwardly from around the circumference of the body portion 9, and a plurality of pawls or pivotable lugs 11 pivotally mounted in an annul recess 12 of the body portion 9 at circumferentially spaced apart locations.
  • the pivotal lugs or pawls 11 of the ratchet sprocket wheels 8 are aligned with inclined teeth 13 positioned around the rotary drive shaft 2, to drive the shaft 2 in one direction of rotation when the ratchet sprocket wheels 8a, 8b and 8c are rotated in that direction but to pivotally cam over the inclined teeth 13 in non-drivi relationship when the ratchet sprocket wheels 8a, 8b and 8c are rotated in the opposite direction.
  • a plurality of elongated driving assemblies 14 are provided, each in ratchet driving engagement with at least one pair of ratchet sprocket wheels 8a and 8b.
  • the driving assemblies include a pair of elongated drive members 15a and 15b, having notch means such as gear teet 16 to mesh with the teeth 10 of the sprocket wheels 8a, 8b respectively, when said drive members are mounted in driving engagement therewith.
  • Elongated drive member 15a is positioned on one side of rotary drive shaft 2 in driving engagement with sprocket wheel 8a on that side, while elongated drive member 15b is positioned on the opposite side of rotary drive shaft 2 and slightly offset to be in driving engagement with sprocket wheel 8b on tha side.
  • elongated drive members 15a and 15b are offset sufficiently for respective engagement with the closely spaced apart ratchet sprocket wheels 8a and 8b, with the ' respective toothed sides of said drive members 15a and 15b facing in a direction inwardly toward the rotary drive shaft 2 and toward each other.
  • a spacing member 17 is bolted or otherwise secured at each end between the elongated drive members 15a and 15b, to space them apart axially of the rotary shaft 2 the proper distance for alignment with their respective ratchet sprocket wheels 8a and 8b, and to space them apart laterally of the rotary drive shaft 2 the proper distance for driving engagement of the gear teeth 16 of drive members 15a and 15b with the teeth 10 of the sprocket wheels 8a and 8b respectively.
  • a float member 18 is secured to the lower end of each driving assembly 14, for contact with the surface of the open body of water on which the wave driven generator 1 is placed. As a wave begins to rise, the float member 18 forces the driving assembly 14 upward causing the ratchet sprocket wheels 8a and 8b which are engaged therewith to rotate in opposite directions, in one of which the pawls 11 of the sprocket wheel catch against the teeth 13 of the rotary shaft 2 to rotate the shaft in that direction and in the other of which the pawls 11 cam over the inclined surface of the teeth 13 in non-driving relationship.
  • each sprocket wheel 8a and 8b rotate in different directions when driving assembly 14 moves upward than they do when it moves downward.
  • sprocket wheel 8a may rotate clockwise and sprocket wheel 8b may rotate counter-clockwise when driving assembly 14 moves upward, and sprocket wheel 8a would then rotate counterclockwise while sprocket wheel 8b would rotate clockwise when driving assembly 14 moves downward.

  • the driving assemblies 14 of this invention are mounted to all drive the rotary drive shaft in the same direction of rotation when the driving assemblies 14 are moved in both directions of reciprocation.
  • Each driving assembly 14 is able to rotate the rotary drive shaft 2 independently of what any of the other driving assemblies 14 may be doing. All may be moved upwardly together at the same time and the driving mechanism described above will enable all of the driving assemblies 14 to drivingly rotate the shaft 2 in the same direction. One may be moved upwardly, while anothe -or all of the others- are moved downwardly, and again all of them will apply driving force to rotary shaft 2 in the same direction of rotation. One driving assembly 14 may be moved upwardly a short distance by a low wave while another may continue upward for a longer distance by a higher wave, and yet both will continue to apply driving force to rotary shaft 2 in the same direction of rotation without one driving assembly 14 working against or opposing another. The same is true on the downward stroke.
