Abstract

A current or tidal power generator comprises a floating moored catamaran, multihull or single hull 6 supporting shafts 3 on which an endless belt 1 with blades 2 is mounted. The movement of flowing water against the blades 2 causes the endless belt 1 to rotate, driving the shafts 3 to generate power. The structure may include a tunnel 4 with splayed mouth 5 where the flowing water enters the structure. The structure may also support a road or platform at 12.

Description

24004 1 3
DESCRIPTION
The invention relates to a means of generating power from water currents or tides.
Various schemes have been developed to obtain energy from water flow, for example turbines in dam walls but this invention will float and can therefore be moored in rivers or offshore in tidal streams.
Propellers and paddle wheels have been used to produce tidal power but this invention is more efficient.
This invention comprises blades attached to an endless belt which is mounted on circular shafts. The upper part of the belt is in the air while the lower part is immersed in the flowing water inside a tunnel. The flowing water inside the tunnel causes the belt to move which then turns the shafts to generate power. The mouth of the tunnel is splayed open to cause greater water entry.
The belts on the shafts are supported on floating hulls which can be separated as a catamaran for stability or alternatively outside a single hull.
The mass of moving water contained between the blades exerts extra power above that of a paddle wheel.
The invention can accommodate the flow of water in opposite directions when the tide changes.
The invention may also operate without the tunnel.
The top deck of the Unit 12 may be used as a platform or road.
A preferred embodiment of the invention will now be described with reference to the accompanying drawing in which:- Figure 1. Is a plan looking on the invention from above.
Figure 2. Is a section along the line C.C.
Figure 3. Is a part front or back elevation on the line A.A.
Figure 4. Is a part section along the line Be Be with the endless belt cover 9 removed.
DESCRIPTION Cont......
Referring to Figure 2.
The endless belt 1. with attached blades 2. is mounted on the circular shafts 3.
The tunnel 4. is shown with the splayed mouth 5.
Referring to Figure 1.
The hulls supportingthe endless belt are shown 6. with the generator 7.
A mesh to prevent the ingress of debris at each mouth is shown at 8.
The approximate floating water level is shown at 10.
The mooring attaching the invention to the river or seabed is shown at 11.
Referring to Figure 3.
The mouth of the tunnel covered with mesh is shown at 8.
Referring to Figure 4.
This shows a front or back view of the blades 2 on the endless belt over the circular shaft with the endless belt cover 9 removed.
A cross section through the hull 6 is shown enclosing the generator 7 which may be positioned elsewhere.

Claims (8)

1. A floating moored catamaran, multihull or single hull! supporting circular shafts on which is mounted an endless belt with blades attached.
2. An endless belt as claimed in 1 where the upper part of the endless belt is in the air while the lower part is immersed in the flowing water inside a tunnel.
3. An endless belt as claimed in Claims 1,2 where the flowing water inside the tunnel causes the endless belt to rotate which then turns shafts to generate power.
4. A tunnel as claimed in Claims 2,3 where the mouths are splayed open to cause greater water entry.
5. An endless belt as Claims 1,2,3 where moving water that is contained between the immersed blades provides energy to rotate the shafts which then provides power to the generator.
6. An endless belt as Claims 1,2,5 without a tunnel.
7. A floating catamaran, multihull or single hull as Claim 1 supporting a road or platform.
8. A floating water power generator substantially as described herein with reference to Figures 1 - 4 of the accompanying drawing
