Definitions

  • the present invention relates to a mass displacement drive and in particular to a mass displacement drive with a Peaucellier mechanism and an offset beam arrangement.
  • Renewable energy devices typically utilize nature to generate a force required to turn a shaft or move a piston to generate energy. For example, wind power, wave and tidal power, solar power or the like. Such renewable energy devices must be located in specific locations, and base load commercial scale units are not portable and are expensive to install and operate.
  • Wind power is limited by its need for a location where the wind is considered reliable. It is rarely constant. The amount of power developed by wind generators varies with wind speed and down time due to the lack of wind on windless days. Wind power also has issues with placement near communities and the concept of ocean based wind power installations suffers from the distance to the nearest electricity grid connection point. [0006] Wave and tidal power installations have not been able to produce a constant power generation due to the nature of the force being used to drive them. Power is only produced intermittently in line with the availability of the waves and tides. Location also forces the use of an expensive underwater cable run to a grid connection point.
  • the vertical mass displacement drive uses an unbalanced power conversion lever, as does the current version of the functioning prototype, then balance can be restored or changed by the use of mass balance weights installed at any appropriate position, allowing the mass balance weights to influence the effect of both the descent and ascent energy potential.
  • the set up can derive energy from both the gravity and buoyancy phases or be setup to derive energy from either phase or derive energy proportionally from each phase as desired.
  • the effect of this is that the vertical mass displacement drive can be considered to be either a 1 stroke or a 2 stroke drive that utilizes the constantly available input energy source of gravity and buoyancy to produce power. Gravity will continue to supply energy input during the descent phase and buoyancy will continue to supply energy input during the ascent phase.
  • a vertical mass displacement drive is one in which the long travel movement of the mass displacement chamber or chambers and their power transmission shafts is constrained in order to produce true vertical motion.
  • the drive that utilizes this displacement of mass i s in a true vertical axis only, throughout the entire length of travel, to transmit energy by connection to a lever.
  • This connection to the lever is made via the use of a novel and redesigned Peaucellier mechanism or other suitable mechanism that can scribe a vertical path derived from the arc of travel of the lever.
  • the lever is constrained at its fulcrum by attachment to a frame or other suitable mounting system.
  • the opposite end of the lever is connected to rotate a shaft via a connecting rod and an offset crank pin.
  • Such a device would allow the vertical mass displacement drive to function as a fully developed power drive system.
  • a vertical mass displacement drive comprising:
  • the chamber havin g a method of varying a displaced mass of the chamber when immersed in a first fluid
  • a second fluid enters and exits the chamber at defined intervals to change the displaced mass of the chamber, generating a vertical movement by creating ascending and descending states
  • the second fluid may be a gas such as air.
  • the ascending state is a positively buoyant state, and wherein the descending state is a negatively buoyant state.
  • the vertical movement is connected by way of a Peaucellier mechanism, the Peaucellier mechanism being arranged to incorporate linear bearings, bushes or other suitable mechanism.
  • the shaft may be rotatabl e about the axis of the shaft when the arm ascends and descends, thereby generating a rotational force for use as energy.
  • one complete ascent and descent phase of the mass displacement chamber will equal one RPM at the rotating shaft.
  • the vertical mass displacement drive may further include a plurality of independent arms and chambers positioned at the same end of the lever or at each end of single or multiple levers.
  • the vertical mass displacement drive may further include a flywheel mounted on the rotating shaft, and the energy generated may be harvested either from the flywheel or directly from the shaft.
  • each chamber moves to a non-buoyant position to create a descending state at the defined interval and the chamber moves to a positively buoyant position to create an ascending state at the defined interval.
  • the arms and chambers may be mountable in multiples or other combinations such as odd and even numbers.
  • the arms and chambers may operate either together, when acting on an attachment point to a lever or multiple levers, or in opposition to each other when acting on opposed ends of any single or multiple levers.
  • a vertical mass displacement drive (Fig. 1 ) having a minimum one vertical arm with a chamber located at the distal end of the arm, the chamber having a method of varying its displaced mass when immersed in a fluid.
  • a second fluid which may be a gas such as air, enters and exits the chamber at defined intervals to change the displaced mass of the chamber, generating a vertical movement by creating ascending (positively buoyant) and descending (negatively buoyant) states.
  • This vertical movement is connected, (which may be via a novel use of th e Peaucellier mechanism whi ch is redesigned to incorporate l inear bearings and or bushes or other suitable mechanism), to a lever or other suitable mechanism, which translates the vertical movement to torque in order to rotate a shaft about its axis.
  • the shaft may be rotated about its own axis when the arm ascends and descends, thereby generating a rotational force for use as energy.
  • one complete ascent and descent phase of the mass displacement chamber will equal one rpm at the rotating shaft.
  • the device may include a plurality of independent arms and chambers positioned at the same end of the lever or at each end of single or multiple levers.
  • the device may use a flywheel mounted on the rotating shaft and the energy generated may be harvested either from the flywheel or directly from the shaft.
  • each chamber moves to a non-buoyant position to create a descending state at the defined interval and then the chamber moves to a positively buoyant position to create an ascending state, again at the defined interval.
  • the arms and chambers although having the ability to be mounted in multiples or other combinations such as odd and even numbers in some embodiments, must always operate either together, when acting on the same attachment point to a lever or multiple levers, or in opposition to each other when acting on opposed ends of any single or multiple levers.

  • Figs, la to 16 show embodiments of a vertical mass displacement drive 100 having a vertical frame 1 10 which can extend from a stabilizing base frame 120, or be constructed directly from ground level.
  • the function of the vertical frame 1 10 could also be achieved by wall mounting or any other suitable mounting system.
  • the vertical frame 1 10 acts as a mounting point for a power conversion lever 130 and the anchor point for a novel Peaucellier mechanism 180.
  • the vertical frame 1 10 may be built in any form or design and in any material strong enough to take the applied load. It may be designed such that any attached displacement chambers 140 and power transmission shafts 150 are used above ground acting in a vessel 160 containing the fluid in which the displacement chambers act. It may also be designed so that the displacement chambers 140 and their power transmission shafts 150 act below ground level or water level in the case of installation within a body of water.
  • the power conversion lever 130 may be a 1 st , 2 nd or 3 rd order lever, which is attached at its fulcrum point to the vertical frame 1 10.
  • the vertical mass displacement drive 100 in the preferred embodiment can utilize both balanced (center fulcrum) or unbalanced (proportional fulcrum) levers.
  • This redesign of conventional beam engine technology allows for increases in torque to be achieved within any given design.
  • the redesign of the conventional beam engine also allows for far greater vertical tra vel of the mass displacement chamber than is available in a conventional beam engine design.
  • This redesign means that as the distance from the fulcrum of the power conversion lever 130 to the centerline of the vertical mass displacement chamber 140 increases, thus increasing the maximum possible amount amount of vertical movement. This redesign also means that by reducing the distance between the fulcrum of the power conversion lever 130 and the connection point of the driven shafts connecting rod, a significant increase in vertical travel of the mass displacement chambers 140 and their power transmission shafts 150 can be maintained while utilizing significantly less travel at the connection to the driven shaft or flywheel 160, thus gaining a significant increase in the derived torque. [0052] The direct result of the redesign of a conventional beam engine is that more power can be applied to the shaft and or flywheel 160 for a longer time period.
  • the vertical mass displacement drive 100 can take a novel advantage of the formulae of mechanical advantage pertaining to levers.
  • the present invention in the preferred embodiment introduces a time factor to the existing lever formulae.
  • the time factor increases the horsepower available at the shaft or flywheel 160 and continues to do so until the mass displacement chamber 140 and associated power transmission shaft 170 design reach their terminal velocity when operating within any given fluid at which point any increase in vertical travel of the mass displacement chambers become irrelevant.
  • the power transmission shaft 170 is connected to the driving end of the power conversion lever 130.
  • the power transmission shaft 170 and the mass displacement chamber 140 move throughout the ascending and descending states in a vertical plane.
  • the travel of the power transmission shaft 170 is constrained by a novel redesi gn of the Peaucellier mechanism 180.
  • This combines the original Peaucellier mechanism with modern linear bearings and or linear bushes.
  • This redesign allows very long travel, power transmission shafts to maintain a vertical plane throughout their entire range of travel.
  • This redesign of the Peaucellier mechanism 180 may be used as a single unit or in multiple units.
  • the installation on the functional prototype shown in Fig. 9 is a dual mechanism installation.
  • the Peaucellier mechanism was published in 1864 and was the first planer linkage capable of transforming rotary motion into a perfect straight line and inversely transforming a straight line into rotary motion. Its greatest advantage was that it was designed to be used without guide ways. Whilst this is true when the mechanism is used in designs with low travel values, when it is applied to long travel designs such as the vertical mass displacement drive it follows a natural tendency to follow the now extended arc of the rotary mechanism.
  • the Peaucellier mechanism 180 design although theoretically perfect was not capable of dealing with the loads generated by the vertical mass displacement drive. In the application for the vertical mass displacement drive the Peaucellier mechanism 180 was redesigned to incorporate a number of modern linear bearings and or l inear bushes.
  • the shaft or flywheel 160 are mounted on the vertical frame 1 10 and are sized in the conventional way.
  • the lever at the power harvesting end is connected to the shaft or flywheel 160 by either a connecting rod or via the novel redesign of the Peaucellier mechanism 180.
  • the induced loss of displacement of the mass of chamber or chambers causes a loss of buoyancy in those chambers and initiates a negative buoyant (non-buoyant, or gravity induced) condition under which the chamber must descend (Mass multiplied by the gravity constant minus the frictional losses minus the entrapped mass). It is therefore also true that an induced increase in the displacement of the chamber or chambers causes an increase in buoyancy in those chambers and initiates a positively buoyant condition under which the chamber must ascend.
  • a mechanism incorporated within the device by means of a mechanism incorporated within the device, the mass of the chamber or chambers is again displaced to their ascending state.
  • the mechanism could for example be a motor, piston, bellows, valve, hinge, elastic, spring or the like.
  • a mechanism, such as a compressor may supply a compressed gas, which may be compressed air, to increase the displacement of the chamber or chambers.
  • the mass of the ascending chamber or chambers is again displaced to the descending state. This results in the mass displacement chamber or chambers traveling from their upper to lower travel limits and returning to their upper travel limits in a continuous cycle.
  • the vertical mass displacement drive 100 in the preferred embodiment is sized for a given power output by calculating the force required at the output shaft or flywheel 160.
  • the required input force at the attachment point of the mass displacement chamber 140 or chambers is calculated as chamber or chambers total volume minus chamber or chambers total mass multiplied by the distance from the attachment point to the lever fulcrum for the ascending state.
  • the power produced during the descending state this would be defined simply as chamber or chambers mass multiplied by the distance from the attachment point to the fulcrum.
  • both the ascending and descending states would need to take account of friction, hydrodynamic drag and other factors. Any number of chambers may act independently of each other if installed at opposite ends of the same lever.
  • any number of chambers may also act in unison if mounted at the same end of a lever. All chambers may be independent of or share a common fluid path to allow the flow of a fluid or mobile media (gas, liquid or mobile solids or fines) between each chamber during operation.

  • the vertical mass displacement drive 100 in the preferred embodiment may be designed with any number of mass displacement chambers 140 arranged in any pattern around a central point. That central point may be the point at which any numbers of levers converge to drive a shaft or flywheel.

  • the vertical mass displacement drive 100 in the preferred embodiment may be installed with a given number of mass displacement chambers 140 and the number of chambers may be increased or decreased by the addition or removal of mass displacement chambers only. This may be done without structural alteration. The only limitation to this is the design integrity of the vertical frame.
  • the vertical mass displacement drive 100 in the preferred embodiment may run in either direction of rotation without change of design.
  • the vertical mass displacement drive 100 in the preferred embodiment may incorporate a pressure storage tank or other storage unit to act as a supply reservoir for the mass
  • pistons may be used to draw air or other gas or mobile media into the chamber to affect positive buoyancy. Movement of the piston creates a drop in pressure that draws air into the chamber. Movement of the piston may be effected by pneumatic means, or by a pneumatic or hydraulic cylinder, or by an electric motor having gearing such as a worm gear or similar mechanical linkage to actuate the piston to draw air into the cylinder. Spring biasing may be used to assist movement of the piston. The device may also be used to expel air or gas from the piston to affect negative buoyancy.
