Abstract

A gyroscopic energy conversion system is installed on a rocking, oscillating or rotating platform 10 for extracting energy from the motion of the platform 10. The system comprises a housing with a ring track or groove 12, a moveable frame 20 supported to revolve about an axis 22 concentric with the ring track 12, and a spinning rotor 30 supported on a spindle 32 which is lies in the plane of the ring track 12 and is perpendicular to the frame axis 22. The spindle 32 is in rolling contact at one or both ends with the ring track 12 as it revolves around the ring track 12, and an electric generator 28 is associated with the spinning rotor 30. The system has at least one one-way clutch 34, 38 so that the spindle 32 will accelerate the rotor 30 when it moves sufficiently fast around the track 12, but the rotor will freewheel at other times so that energy is not lost.

Description

ROCKING MOTION ENERGY CONVERTER
Field of the invention
The present invention relates to a device for converting rocking motion energy to electricity, for example converting ocean or sea wave energy to electricity.
Background of the invention :10
Most developments of wave power have concentrated on the compatibility of conversion of the wave energy in a form suitable for generation of electricity using high speed rotary generators. Examples such as the Salter Duck, McCabe Wave Pump, OPD PelamisTM, OPT PowerbuoyTM etc employ hydraulic power systems to convert the low speed reciprocating motion of the waves (typically 0.5 to 5 m/s) into high speed rotational motion suitable for interface with an electric generator running at an air-gap velocity of typically 50 rn/s or higher. The mechanical system required for the above speed conversion is the most complicated and costly part of a wave energy converter. In addition, hydraulic systems have high energy losses and require regular maintenance which is difficult on the high seas.
A rocking motion energy converter based on gyroscopic momentum transfer derived from the periodic tilting motion of a rocking platform, described in GB2409898A, GB2410299A and GB2410300A could overcome the above speed conversion problem energising a rotor at high speed suitable for interface with an electric generator. In these systems, it is necessary to use either a reactive control system or a proactive control system to adjust the rotating speed of the spinning rotor in the gyroscopic system in response to the tilting frequency of the rocking platform such that the rotor gains rotational energy by synchronised transfer of angular momentum from the rocking platform when the precession frequency of the rotor matches with the tilting frequency of the platform. However, in the case of surface waves, there are difficulties in achieving syrichronised control because of the unpredictable nature of the frequency, amplitude and direction of the waves and the high inertia of the spinning rotor taking considerable time to change speed in response to the waves.
Aim of the invention The present invention aims to improve the synchronised control of the rocking motion energy converter in response to any frequency, amplitude and direction of the rocking motion.
Summary of the invention
According to the present invention, there is provided a gyroscopic energy conversion system installed on a rocking, oscillating or rotating platform for extracting energy from the periodic tilting motion of the gyroscopic axis of the system on the platform, the system comprising a housing with an internal ring track or groove, a moveable frame supported within the housing to revolve about an axis concentric with the ring track, a spinning rotor supported on a spindle within the revolving frame to rotate about another axis which is perpendicular to the revolving axis of the frame and which lies in the same plane as the ring track in the housing such that the spindle engages in rolling contact at one or both ends with the side wall or walls of the ring track while it revolves and rolls around the ring track, and an electric generator interfacing with the spinning rotor for converting any rotational energy of the rotor to electricity, the system further comprising at least one one-way clutch disposed either between the rotor and the spindle or between the spindle fixed to the rotor and an element around the spindle in rolling contact with the ring track, the one-way clutch permitting direct driving of the spinning rotor when respectively the rotating speed of the spindle is faster than the rotating speed of the rotor or the rotating speed of the element around the spindle is faster than the rotating speed of the spindle fixed to the rotor, and free wheeling of the spinning rotor when respectively the rotating speed of the spindle is slower than the rotating speed of the rotor or the rotating speed of the element around the spindle is slower than the rotating speed of the spindle fixed to the rotor.
The one-way clutch may be a roller clutch or a sprag clutch which is automatic, or it may be a disc clutch controlled by an actuator programmed to engage for direct driving in one direction and disengage for free wheeling in the other direction.
The term "rocking platform" is herein defined as a platform subjected to all types of movements producing periodic tilting motion of the gyroscopic axis of the energy conversion system installed on the platform. In the same context, a rocking motion energy converter is herein defined as an energy converter installed on the above-defined rocking platform.
In the invention, the one-way clutch automatically drives the spinning rotor at times when there is positive transfer of angular momentum from the rocking platform, but allows free wheeling of the spinning rotor without destroying its momentum at other times when there is negative transfer of angular momentum from the rocking platform. Thus without any external assistance, the gyroscopic energy conversion system will automatically lock on to the excitation frequency of the tilting motion of the rocking platform such that the rotor gains rotational energy by the selective driving action of the one-way clutch when there is synchronised transfer of angular momentum from the periodic tilting motion of the axis of the revolving frame which is the precession axis of the spinning rotor, causing the spindle to drive the rotor at the correct phase relative to the tilting frequency while the spindle or the element around the spindle rolls along the ring track driven by the precession motion of the revolving frame.
The gyroscopic energy conversion system of the present invention may therefore be designed to be self-contained and self-regulated, automatically locking on to the excitation frequency of any periodic tilting motion of the gyroscopic axis of the energy conversion system installed on the platform in any operating environment, thus eliminating the need of the reactive control system described in GB2409898A, and adding to the function of the proactive control systems described in GB2410299A and GB241O300A.
The present invention may therefore be used in a floating platform such as one described in GB2409898A, set into periodic motion by ocean or sea waves for the system to extract energy from the waves. It may also be used in a submerged platform, such as one described in GB2410299A, set into periodic motion by ocean or river currents for the system to extract energy from the currents. Indeed, it may be used in any platform set into periodic motion by any energy means for the system to extract energy from that means, including energy from rotating motion such as one described in GB2410300A.
In any of the above applications, the axis of the revolving frame may be resiliently supported to revolve about a conical amplitude substantially concentric with the ring track for the axis to tilt as the frame rotates in response to the pitching and rolling motions of the rocking platform thereby bringing the spindle or the element around the spindle into continuous rolling contact with the side wall or walls of the ring track. -5-.
Alternatively, the axis of the revolving frame may be rigidly supported to revolve about an axis concentric with the ring track for the spindle or the element around the spindle to be in permanent gear wheel contact with a gear rack around the ring track.
Finally, the system may further comprise an electric motor for driving the rotor during start up of the gyroscopic energy converter so as to spin up the rotor independent of the rotating speed of the spindle or the rotating speed of the element around the spindle. The presence of the one-way clutch lends itself conveniently to this operation at any time as required. For compactness, the electric generator and electric motor in the energy converter may be integrated into a combined generator/motor unit.
Brief description of the drawing
The invention will now be described further by way of example with reference to an accompanying drawing which is a schematic cross-sectional view of a gyroscopic energy conversion system of the present invention.
Detailed description of the preferred embodiment
The present invention relates to a key improvement feature (i.e. the one-way clutch) incorporated into the design of a gyroscopic energy conversion system used in a variety of applications described in GB2409898A, GB2410299A and GB2410300A. Figure 1 shows specifically the deployment of the one-way clutch in a generic layout within the schematics of a gyroscopic system mounted on a rocking platform subjected to periodic rocking or tiling motion.
In Figure 1, the gyroscopic energy conversion system comprises a housing 10 with an internal ring track or groove 12, a moveable frame 20 supported within the housing 10 to revolve about an axis 22 concentric with the ring track 12, a spinning rotor 30 supported on a spindle 32 within the revolving frame 20 to rotate within supporting bushes 26 about another axis 32 which is perpendicular to the revolving axis 22 of the frame 20 and which lies in the same plane as the ring track 12 in the housing 10 such that the spindle 32 engages in rolling contact at one or both ends with the side wall or walls of the ring track 12 while it revolves and rolls around the ring track, and an electric generator with stator disk 28 interfacing with the spinning rotor 30 for converting any rotational energy of the rotor to electricity.
The system in Figure 1 further comprise at least one one-way clutch disposed either at 34 between the rotor 30 and the spindle 32 or at 38 between the spindle 32 fixed to the rotor 30 and an element 36 around the spindle 32 in rolling contact with the ring track 12. The one-way clutch 34 or 38 permits direct driving of the spinning rotor 30 when respectively the rotating speed of the spindle 32 is faster than the rotating speed of the rotor 30 or the rotating speed of the element 36 around the spindle is faster than the rotating speed of the spindle 32 fixed to the rotor 30, and free wheeling of the spinning rotor 30 when respectively the rotating speed of the spindle 32 is slower than the rotating speed of the rotor 30 or the rotating speed of the element 36 around the spindle is slower than the rotating speed of the spindle 32 fixed to the rotor 30.
The one-way clutch 34 or 38 may be a roller clutch or a sprag clutch which is automatic, or it may be a disc clutch controlled by an actuator programmed to engage for direct driving in one direction and disengage for free wheeling in the other direction.
In the invention, the one-way clutch 34, 38 automatically drives the spinning rotor 30 at times when there is positive transfer of angular momentum from the rocking platform 10, but allows free wheeling of the spinning rotor 30 without destroying its momentum at other times when there is negative transfer of angular momentum from the rocking platform 10. Thus without any external assistance, the gyroscopic energy conversion system will automatically lock on to the excitation frequency of the tilting motion of the rocking platform 10 such that the rotor 30 gains rotational energy by the selective driving action of the one-way clutch 34, 38 when there is synchronised transfer of angular momentum from the periodic tilting motion of the axis 22 of the revolving frame 20 which is the precession axis of the spinning rotor 30, causing the spindle 32 to drive the rotor 30 at the correct phase relative to the tilting frequency while the spindle 32 or the element 36 around the spindle rolls along the ring track 12 driven by the precession motion of the revolving frame 20.
The gyroscopic system in Figure 1 may be used in a floating platform, such as one described in GB2409898A, set into periodic motion by ocean or sea waves for the system to extract energy from the waves. It may also be used in a submerged platform, such as one described in GB2410299A, set into periodic motion by ocean or river currents for the system to extract energy from the currents. Indeed, it may be used in any platform set into periodic motion by any energy means for the system to extract energy from that means, including energy from rotating motion such as one described in GB2410300A.
In Figure 1, the revolving frame 20 is supported by bushes 24 for rotation around fixed pins mounted resiliently to the housing 10 so that the axis 22 of the revolving frame can wobble about a conical amplitude for it to tilt as the frame 20 rotates in response to the pitching and rolling motions of the rocking platform 10 thereby bringing the spindle 32 or the element 36 around the spindle into continuous rolling contact with the side wall or walls of the ring track 12.
Alternatively, the revolving frame 20 may be supported by bushes 24 for rotation around fixed pins mounted rigidly to the housing 10 so that the axis 22 of the revolving frame 20 is always perpendicular to the plane of the ring track 12 and the spindle 32 or the element 36 around the spindle is in constant alignment with the side wall of the ring track 12. In this case, one end of the spindle 32 or one element 36 around the spindle may be provided with a gear wheel in permanent mesh with a gear rack on one wall of the ring track 12 (not shown in Figure 1) for driving the rotor 30 as the spindle 32 rolls along the ring track 12 driven by the precession motion of the revolving frame 20.
Finally, the system in Figure 1 further comprises an electric motor with stator disk 28 interfacing with the rotor 30 for driving the rotor 30 during start up of the gyroscopic energy converter so as to spin up the rotor 30 independent of the rotating speed of the spindle 32 or the rotating speed of the element 36 around the spindle. A start-up button or an automatic switch (not shown) may be provided for that purpose. The presence of the one-way clutch 34, 38 lends itself conveniently to this operation at any time as required. For compactness, the electric generator and electric motor in the energy converter may be integrated into a combined generator/motor unit with a common stator disk 28.
The gyroscopic energy conversion system of the present invention has the advantage that the energy conversion would continue as long as the periodic motion continues driven over a wide range of excitation frequencies. The system is self-contained and self-regulated, automatically locking on to the excitation frequency of any periodic tilting motion of the gyroscopic axis of the energy conversion system installed on the platform in any operating environment including wind, currents, waves or other energy sources producing mechanical oscillations.
In one example, a rocking motion energy converter may be strapped to the foot or leg of a cyclist generating electricity as he pedals. In another example, a battery powered device may be recharged by swing action of a hand-operated rocking motion energy converter. In a further example, an array of aerodynamically designed rocking motion energy converters may be distributed along the roof, walls and edges of a building for capturing the energy of air currents sweeping around the building and producing oscillations to the energy converters.
