Description

TITLE: Wave Power Converter
Description of this invention:
FIELD OF INVENTION
This invention relates to usages of wave, tide and turbulence energy and it relates to a process of converting ocean wave energy into mechanical and electric power.
BACKGROUND OF INVENTION
Ocean wave energy is very abundant, free and inexhaustible source of energy. The technique of using this energy has been developed for many years with some successes. In the past, many attempts to harness wave energy had been made by various inventors. Wiggs (U.S. Pat. No. 4,725,195) developed a method, which extract wave energy by using paddle wheels and pontoons. Ivy (U.S. Pat. No. 4,392,060) converted the vertical wave motion of a float by using a ratchet-geared rack. Azimi (U.S. Pat. No. 5,084,630) designed power generator, which used a plurality of paddle and hydraulic cylinder units operating in the path of waves to drive a hydraulic pump. Kvaerner Brug (AU Pat. No. 538060) develop his turbine drive system with water oscillating between two communicating chambers. Of these devices above, ocean wave energy was converted directly into mechanical energy. Hydropneumatic machines are also developed which used the up and down ocean wave surface to push air to flow in and out a "T" tube and produce one-way flow air which drived an air turbine. Other designs of hydropneumatic machine were made by Woodman (U.S. Pat. No. 4,098,081), De long (U.S. Pat. No. 145,578), Barwick (U.S. Pat. No. 3,925,986) and Paulson (U.S. Pat. No. 2,484,183) for converting tidal energy. These devices were very complex and it is very difficult to use these design in large scale. These designs are focused on using a small part of ocean energy, eg ocean surface wave energy or tidal energy. But the energy exists in the whole ocean water body. Thus, the efficiency of using ocean energy is very low. Furthermore, hydropneumatic machine uses multiple energy conversions, which limit the energy conversion efficiency and complicate the whole system, resulting in an increase in the installation and maintenance costs. The present inventor follows a new approach to solve these problems and let large scale of using ocean energy become possible. SUMMARY OF THE INVENTION
As known that ocean wave, tide and turbulence can cause water to move up and down, back and forth at all possible directions. To use these kinds of kinetic energy, which exists in random movements of water efficiently, a process of converting these movements into one-way flow is developed. By placing a paddle wheel or turbine on the flowing path, ocean energy can be transferred directly into mechanical power. The apparatus of this one-way flow process, which can be submerged under water, fixed on the seabed or floating on the ocean surface, comprises of a tank and two sets of one-way flow valves fitted on the tank. One set of the valves (inlet valves) allows liquid flow into the apparatus only and another set of the valves (outlet valves) allows liquid flow out the apparatus only. These valves are made that when the pressure of one side of the valve (front side F) is higher than the pressure of another side (back B), the valves allow liquid flow through from side F to side B, but not the other way round even if the pressure of the backside B is higher. The result of this process causes liquid inside the apparatus to flow in one-way direction from inlet to outlet. Thus, the liquid in the apparatus can drive wheel or turbine to rotate in one direction.
To use the paddle wheel or turbine to propel an electric power generator, ocean power can be converted directly into electric power, or to propel a pump, water can be pumped to higher level. If a plurality of these pumps is used to pump a large amount of water to a huge tank or dam, the amount of water in the tank or dam will be large enough to drive a conventional water power station, which can produce a stable output of electricity.

DETAILED DESCRIPTION OF THE INVENTION
As known that ocean wave, tide and turbulence can cause water to move up and down, back and forth at all possible directions, which causes the water pressure in ocean to fluctuate periodically. To use this kind of energy, which exists in random movements of liquid, it is better to convert the moving direction of liquid into oneway flow. An apparatus of this one-way flow process is described in Fig. 1 A. All of the designs described here can be used for all kinds of liquid including water. The apparatus comprises of a tank 2, at least an inlet valve 3 as the inlet of the tank for liquid and at least an outlet valve 4 as the outlet. The tank is positioned in the liquid. The inlet valve, which is fitted on the tank as the inlet, is made that it allow liquid to flow into the tank only and does not allow liquid to flow out. The outlet valve, which is fitted on the tank as the outlet, allows liquid to flow out of the tank only and does not allow liquid to flow in. Thus, as shown by the arrows 1 in Fig. 1A, liquid inside the tank flows in one direction from the inlet to the outlet. Fig. 1B is the same design of Fig. 1A without covering the top of the tank. This design works at liquid surface only. The line 8 shows the level of liquid, which is lower than the edges of the tank. Fig. 2 is the same process of Fig. 1 A for pipe 5 instead of tank. The inlet valve is fitted on one end of the pipe 5 and the outlet valve is on another end. The advantage of this design is that the inlet valve and outlet valve can be positioned on two different positions to maximum the amount of liquid flowing through the pipe. Fig. 3 shows another design of the apparatus, which uses a plurality of inlet and outlet valves. This design allows liquid to flow into the tank from the inlet valves at the upper part and flow out from the outlet valves at the lower part, as shown by the arrows 1. More inlet and outlet valves are used because they allow more liquid flowing through. The processes presented in Fig. 1A, Fig. 2 and Fig. 3 can work at any part of the ocean. It can be submerged under water, fixed on the seabed or floating on the ocean surface.
The designs for inlet valve and outlet valve are the same except for the way the valves are fitted to the tank. The pressures of liquid inside and outside the tank control the operations of these valves. Fig. 4 shows two designs of the valves. The valves are designed that when the pressure of liquid at the front side F is higher than the pressure at backside B, the valves open and allow liquid to flow through. But the valves close when the pressure at front side F is smaller than the pressure of backside B. In Fig. 4A, the valve comprises of a hole for liquid flowing through, a sheet, with flexibility, covering the hole from the backside B. A point or the upper edge of the sheet is fixed to the corresponding edge of the hole. Another design is described in Fig. 4B. The valve comprises of a hole for liquid flowing through, a sheet covering the hole from the backside and a spring 6 pressing the sheet gently to the hole. For these two designs, the higher pressure at the front side F than the backside B pushes the sheet to open and allow liquid to flow through. The lower pressure presses the sheet to close the hole. The inlet valve and the outlet valve are distinguished by the way of fitting the valve. For inlet valve, its front side F is fitted towards outside of the tank and its backside B towards inside of the tank. For outlet valve, the front side F is fitted towards inside of the tank and the backside B towards outside.
One of the designs of wave power converter is described in Fig. 5. It uses the oneway process presented in Fig. 1 B. A paddle wheel 7 is positioned on the flowing path and is propelled by the current of liquid. The arrow on the paddle wheel shows the direction of its rotation. The apparatus should be installed that the height of the liquid surface (line 8) is below the axis of the paddle wheel. The external device 9, shown by the dashed line, is propelled by the paddle wheel and is used to convert the mechanical energy of rotary of the paddle wheel into other kinds of power. If the device 9 is a pump or electric generating equipment, the whole system becomes a wave pump or a wave electric power generator. The second design is described in Fig. 6, which uses the design presented in Fig. 3. The inlet valves 3 are fitted at the upper part of apparatus and the outlet valves 4 are fitted at the lower part. Thus, liquid flows from the upper part towards the lower part, as shown by the arrows. A turbine 10 is fitted on the flowing path and propelled by the liquid. The turbine propels the external device 9, which transfers the power of rotary into other kinds of power. The third design is described in Fig. 7. A chain 11 connects a plurality of plates 12 in a form of cycle as shown by the diagram. The flowing liquid drives the plates fitted on the chain to move in a direction described by the arrows on the plates. The two wheels are used to support the chain and are propelled by the chain to rotate. The line 8 shows the liquid level, which is below the axis of the wheels. As the same as shown in Fig. 5 and Fig. 6, the external device 9, shown by the dashed line, is either a pump or electric generating equipment.
Comparing with the designs by other inventers, the advantage of these designs of wave power converter above is that it can use the ocean energy at the ocean surface and deep under ocean water by increasing the sizes of the inlet and outlet, and the system is much less complex.
One of the disadvantages of the wave electric power generator described in Fig. 5, Fig. 6 and Fig.7 is that its output of electricity is not stable and is affected by the sizes and the strengths of the ocean wave, tide and turbulence. When the ocean is quite and smooth, the output of power becomes very small. To stabilize the output, a new approach has been developed as shown in Fig. 8. A series of wave pumps (P1, P2, ..., Pn) are used to pump water into a huge tank or a dam 14, which is installed at a level higher than the ocean surface. The amount of the pumps used depends on the amount of power to be generated. The sizes of the tank or the dam should be large enough that its water level is not affected significantly by the short- term variations of the ocean wave. Then, the water, as a stable water source, is used to propel a conventional water power station 15 for generating stable output of electricity.
