Abstract

A tethered barge generates electricity from sea waves and currents using a combination of generators. A heavy wheeled bogie or truck D is mounted on inclined rails and connected to the mooring cable, so that tension in the cable pulls the bogie up the rails, and it descends due to its weight when tension reduces. Power may be extracted by rotary generators driven by a rack and pinion, linear generators or hydraulic pumps. The weight of the bogie (and of the barge) may be adjusted e.g. by adding or removing water to tune response characteristics. The pivot point A of the mooring cable is adjustable to further control response. An inertial generator may be used comprising a weight mounted on a horizontal track or pendulum. Floating buoy turbines may be used with pivoted vanes (figure 3).

Description

I
BARGE GENERATOR
DESCRIPTION
1/ A floating vessel in the form of a hull shape similar to a common river barge. The barge is anchored to the sea bottom (or another barge) by a chain terminating in a cable/hawser which runs over a bow roller at A (see Fig I & 2) and activates a reciprocating pull generator D (see Fig 2). The pull generator is a heavy (lead loaded) wheeled bogie that runs in tracks inside the barge hull. The tracks, both above and below the bogie wheels W (see Fig 2) allow it to run back and forth up and down an inclined plane inside the hull. Movement of the barge and the varying pull of the anchor cable will cause the bogie to move back and forth in its tracks generating electricity (on both the up and down of the bogie strokes) from: 2/ Two rotary electric generators that are mounted on the bogie (D) and driven by toothed pinions running in a fixed toothed rack mounted parallel to the rails (R & P).
3/ Static hydraulic rains/recoil buffers that are mounted at the top and bottom of the tracks HR (in Fig 4). These are connected to a closed hydraulic generating system which turns a turbine (T) directly linked to an electric generator (see Fig 4). The movement of the bogie at the top and bottom of its run pumps fluid that is used to rotate the unidirectional turbine (T see Fig 4) driving the rotary electric generator and re expanding whichever rant is not then under compression. When the top buffer is pushed in by the bogie the fluid re extends the lower buffers (and vice versa) as well as generating electricity. Return springs S assist with the return. Four simple but heavy duty flap valves (see valves in VI and valves out VU in fig 4) are used. The valves and back pressure in the hydraulic line from the cylinder under conipression ensures that fluid through the turbine is only one way. The hydraulic rains can be replaced by linear electric generators that would generate electricity on both the up and down strokes.
4/ A Rolling Action Actuator (Fig 5) mounted horizontally and located at Q (In Fig 2) within the barge hull provides side to side movement relative to the barge rolling in the waves. The rolling side to side action of Actuator K (see Fig 5), which is pivoted with a swivel at point P1, operates the two hydraulic rams HR. This in turn operates a secondary hydraulic generating system identical to that in Fig 4. The actuator, in order to maximise inertia, is pivoted at P1, weighted at W and is permitted to roll freely and swivel directionally shown by A and B. The hydraulic rams can be replaced by linear electric generators that would generate electricity on both the side to side strokes.
5/ A Bogie system such as that mentioned in I above but mounted on horizontal tracks side to side across the beam and at approximate right angles to the longitudinal axis of the barge can be used together with generating systems such as those mentioned in 1,2,3 and 4 above in addition to or substitution for the Rolling Action Actuator.
6 Unique curved and hinged (alternatively flat) rotary buoy impellers (see Fig 3) rotate the three Buoys (B 1,2 and 3 in Fig I) because of the wave and current action on them -transmitting rotary motion to electric generators or hydraulic pumps mounted on the top (out of the water) of their retaining cages (C,C1,2,3,&C4). The generator at B2 being an identical but laterally inverted arrangement to that at Bi. Buoy B3 is mounted in board with the same principle of generation but. no articulating cage. Keeping the generators above the usual surface level of the sea is a particularly important innovation for their reliability in a sea based machine.
These generators pick up the motion on a toothed pinion which runs in a circular rack (TT in Fig3) that is around the circumference of each buoy. The vanes F (which are part closed) of the buoy open and close because of gravity and the effect of the passing water on them.
The two side (outrigger) buoys have conical ends to help dissipate lateral wave shock. The two generators on the outrigger buoys can also be mounted inboard the barge with universal couplings and spline shafts linking to the pinion drive pickup on the top of the retaining cages. This would have the effect of keeping all generators dry. The inboard buoy runs in the recessed bottom of the barge with the buoy flaps extending into the current under the barge. The buoy vanes are hinged to open out and catch the wave force on one side only (the wave/current closing the other side) thus causing the buoy to rotate. The vanes are manufactured of high strength spring material enabling them to deform then return to their pre-set profile should the waves be outside of their safe loading range. The 2 outrigger buoys are pivoted (at P1) to rotary couplings and the cage they run in (C, Cl, 2, 3, &C4) is hinged to articulate at P so the floating buoy and cage can rise and fall (in relation to the sea and the barge). The outboard generators (if used) are connected to the barge by flexible cables hung from the barge superstructure. The permitted articulation of the outriggers assists with causing motion to the Rolling Action Actuator.
7/ The location of the bow roller A is adjustable from the niidline of the barge to one side (the offset being dependent on the degree of reciprocating pull required to be engendered on the anchor chain to ensure the bogie never becomes static at the top of its run because of equilibrium between the barge and wave/air forces acting on it or excessive constant pull). The degree of A's offset is adjusted by a microprocessor via a screw acting on the side of the bow roller carriage. When the bogie has a good up and down motion the bow roller A would be in the midline position. In other conditions A would be offset to cause some varying straining of the barge on/at its anchor.
A microprocessor aforementioned picks up bogie movement front track sensors and the pressure in the hydraulic rams.
8/ The body of the bogie D (Fig 2) itself is a hollow tank with water in it which is kept stable by internal baffles. The tank internal water level is adjustable via a flexible hose which exits the tank top and is suspended above the moving bogie (allowing it to follow the motion of the bogie). The microprocessor senses sea conditions and pull on the anchor to fine tune/adjust the weight of the water in the bogie (pumping it in and out) to keep it in the optimum weight/position for generating via the reciprocating motion of the ship in relation to the varying ocean motion and pull on the anchor. The same microprocessor also adjusts overall barge buoyancy.
9/ The bogie track is not a uniform incline but increases towards the bow (and flattens off towards the stern) to increase the range of useful generating motion (in high and low seas). Electricity can be transferred from the generators by a suspended cable or brushes on the track.
10/ Electricity is rectified and collected in batteries (from all sources) on the barge then transmitted down a cable connected to the lower portion of the anchor chain through dry waterproof couplings that can be connected/disconnected underwater as an aid to easy maintenance.
11/ Overall buoyancy control is via the microprocessor mentioned above (and monitored remotely by radio at a land based control centre). The height of the barge and buoys above the sea can be controlled by the buoyancy of the barge hull and the buoys. Generally these would run dry but would be part flooded to drop the above waterline profile (included in specialised versions for very rough locations).
12/ A scaled up but optimum buoy size should aim to produce 300A per unit in moderate sea conditions the effective generating range being 200-500A (1200A per barge). The hydraulic venturi Q of the push/pull generators will be such as to provide a general turbine speed of over 500rpm. Mechanical gearboxes will do likewise for the other generating power inputs. Close coupled linear electrical generators can be used as alternatives to the hydraulic rams.
13/ If non costal applications are required then the barges are anchored to submerged stable surface/mid water pontoons (or other barges) that are themselves anchored to the sea bottom. Maintenance can be canied out by replacement of bolt on units or substitution of the barge with another on a periodic basis.
14/ Fabrication may take place in remote areas. Depending on local conditions, availability of materials and labour sonic generating components may be dispensed with as a trade-off of overall efficiency to ease of fabrication. Basic barges with just outrigger rotors or a scaled up internal reciprocating pull generators would still be sufficiently efficient to be commercially worthwhile (depending on location).
15/ The barge is Green friendly with modest construction costs. lis versatility, efficiency, simplicity of operation and zero pollution gives it great advantages over alternative systems.
