Abstract

At least one flexible balloon or bladder 1 floats on water 2 and is fluidly connected to at least one pipe 8. When waves flow over the balloon or bladder 1 a pressure is exerted causing it to deform and increase the pressure in the pipe 8 which can be used to drive an electrical generator or pump 5, eg by means of a turbine. The balloon or bladder 1 preferably has an inlet 3 and outlet 4 fitted with non-return valves to allow a continuous flow of air to a generator 5. The balloon or bladder 1 preferably self re-inflates after a wave. Preferably the fluid in the balloon or bladder is air 6, and the pump may feed a water reservoir which feeds an electricity generator as in a hydroelectric dam. There may be two or more balloon or bladders and pipes and there may be surplus pipe leading to the balloon or bladder and the pipe may be staked to the sea bed 7.

Description

Storm resistant wave power generator This invention relates to a method of harnessing the energy of waves and converting it to electricity in a manner which is storm resistant.
There are many different wave power inventions that show promise, however in stormy oonditions they may become damaged and they are possibly not resistant from a ship oollision. To overoome this, the present invention proposes at least one flexible balloon or bladder floating on water, said balloon or bladder fluidly connected to at least one flexible pipe, deformation of said balloon or bladder due to waves causing fluid pressure in said pipe to drive an electrical generator and/or a pump.
When waves flow over the balloon or bladder a pressure will be exerted on it causing it to deform and exerting pressure into the pipe which can be used to drive the electrical generator or pump. The weight of the pipe helps to give resistance to the balloon or bladder under movement of the waves to harness energy from them. Due to the flexible nature of this system it would be resistant to damage in storms and collisions from boats, tending to deform rather than break. The material costs may also prove cheaper than their solid counterparts resulting in cheaper electricity.
Preferably, said balloon or bladder is self inflating.
Preferably, two or more balloons or bladders are used.
Preferably, two or more pipes are used.
Preferably, said electrical generator and/or pump is driven by a turbine.
Preferably, said balloon or bladder has an inlet and an cutlet fitted with non-return valves to pump said fluid to said electrical generator and/or pump.
Preferably, said outlet supplies said fluid pressure to a higher pressure side of said turbine.
Preferably, said inlet accepts lower fluid pressure from lower pressure side of said turbine.
Preferably, said pump pumps water to a water reservoir which in turn drives an electric generator.
Preferably, surplus pipe is laid to said balloon or bladder to allow said balloon or bladder to rise and fall with tides.
Preferably, said pipe is staked to a sea bed to keep said balloon or bladder in a general area.
Preferably, said fluid is air.
Preferably, fluid cycle is closed. n
An example of the invention will now be described by referring to the accompanying drawing: -figure 1 shows a side view of storm resistant wave power generator according to the invention.
At least one flexible balloon or bladder 1, which may be self inflating at sea level pressures, floats on water 2 which is fluidly connected to at least one pipe 6. When waves flow over the balloon or bladder a pressure is exerted on it causing it to deform and increase the pressure in the pipe which can be used to generate electricity or turn a pump. The balloon or bladder is preferably fitted with an inle 3 and outlet 4 with non-return valves to allow a continuous flow of air o a generator or pump 5, wherein the outlet supplies compressed fluid to a higher pressure side of a turbine and the inlet accepts lower pressure fluid from the lower pressure side of the turbine.
Preferably the fluid in the balloon or bladder is air 6, and preferably the pump feeds a water reservoir which feeds an electricity generator as in a hydroelectric dam. There may be two or more balloons or bladders and pipes and there may be surplus pipe leading to the balloon or bladder to allow for rising and lowering tides and the pipe may be staked to the sea bed 7.
Under influence of a wave the balloon or bladder pressurises and the inlet non-return valve closes and the generator non-return valve opens feeding air to the electrical generator or pump.
When the balloon or bladder re-inflates after a wave, the pressure inside the balloon or bladder will drop and air will flow into the inlet non-return valve, while the non-return valve to the generator closes.
The flow of the air may be a closed cycle, no loss or gain of air, so that filters are not required.
The means for generating electricity can be positioned either on the sea bed, or on a floating platform or structure attached to the sea bed similar to a gas or oil rig, or on land. This enables the solid part of the invention to be kept away from the waves, with only flexible parts exposed to the waves and thus storms and shipping.
Many balloons or bladders can all be linked to higher and lower pressure pipes enabling energy fields to supply the turbines for the generators or pumps.
