Abstract

A bladder 1 of a wave power generating device. The bladder is filled with foam 2 and fluid (air). The bladder is connected to pipe(s) 3, which is connected to hollow container(s) 4 having a plurality of holes 5 allowing passage of the air but preventing passage of the foam. Air can travel via pipes 10, 8 through one-way valves 9, 11 to feed the turbine 12 of the storm resistant wave power generator. The hollow container may be made of semi flexible plastic. When the bladder is compressed by waves, the foam acts to re-inflate the bladder. The bladder may be filled with foam chunks (6, figure 2) or foam cage (7, figure 3).

Description

Breathing device for storm resistant wave power generator This invention relates to a device that allows the bladders of a storm resistant wave power generator to compress and breathe easier while under wave compression.
To make the bladders of the storm resistant wave power generator re-inflate after a wave compresses them foam is added. However, if small pieces of foam is used they would require a filter or net to prevent them from entering into the pipes the bladders are connected to. Using a solid block of foam could overcome this, however, in all cases of foam the air would have to bypass through all of the foam to get to the pipe which makes compression more difficult and creates extra resistance. To overcome this, the present invention proposes at least one flexible bladder of a wave power generating device, wherein said bladder is fluidly connected to at least one pipe wherein said bladder is filled with foam, wherein said bladder is filled with a fluid, wherein said pipe is fluidly connected to at least one hollow container wherein said hollow container has a plurality of holes, wherein said hollow container is inside said bladder, wherein said hollow container is surrounded by said foam, wherein said plurality of holes prevent an entry of said foam into said container wherein said plurality of holes allow entry of said fluid into said pipe when said bladder is compressed wherein said fluid is air.
When the bladder is compressed by waves the hollow container in the centre has a larger surface area than the pipe that the air is compressed into which reduces the amount of foam that the air has to pass through which greatly reduces the resistance that the air sees.
Preferably, there are two or more bladders.
Preferably, said hollow container is semi-flexible. Preferably, said hollow container is composed of plastic. Preferably, there are two or more hollow containers. Preferably, there are two or more pipes.
An example of the invention will now be described by referring to the accompanying drawings: - figure 1 shows a side view of breathing device for storm resistant wave power generator and; - figure 2 shows a side view of breathing device for storm resistant wave power generator and; - figure 3 shows a side view of breathing device for storm resistant wave power generator and; - figure 4 shows a side view of breathing device for storm resistant wave power generator according to the invention.
A bladder 1 which is filled with foam 2 is connected to at least one pipe 3 which is connected to at least one hollow container 4 which has a plurality of holes 5. There may be two or more bladders and there may be two or more hollow containers and there may be two or more pipes and the hollow container may be made of plastic and the hollow container may be semi flexible.
A semi-flexible container prevents the container from breaking if the bladder is very heavily compressed by waves.
Figure 2 shows chunks of foam 6 used to re-inflate the bladder. Figure 3 shows a hollow cage of foam 7 which helps to reduce the amount of foam required and also reduces the need for the hollow container with holes inside the bladder. However, using the container with holes ensures that even if the foam cage is excessively compressed air is still able to flow with reduced resistance.
Figure 4 shows two hollow containers per bladder connected to two pipes to allow for reduced resistance during re-inflation of the bladders when connected to a lower pressure pipe 8 via one way valves 9 of the storm resistant wave power generator and reduced resistance compression which feeds the higher pressure pipe 10 via one way valves 11, the higher pressure pipe feeding the turbine 12 of the storm resistant wave power generator.
