Definitions

• the present invention relates to a method of utilizing the energy in the surface waves in a body of liquid, such as the waves on the surface of an ocean, said method being of the kind in which the wave movements are utilized to move one or more elongated flexible tubes which are divided into a number of sections by means of fluid-tight transverse walls with non-return valves therein adapted to open in the same direction.
• the wave movements induce a potential and/or kinetic energy in a liquid - normally the same as in the surrounding body of liquid - flowing through the tube or tubes, and this energy may be transferred to one or a number of energy transforming units, such as turbines or the like.
• a first chamber or air chamber which is closed on all sides and adapted to contain a gas or a gas mixture, such as air, and
• buoyancy means such as the surface float disclosed in the above-mentioned GB-PS No. 2,024,957
• this gas, gas mixture or air will act as a pressure accumulator accumulating pressure energy during movements downwards into the trough of the waves, releasing this energy during movement, upwards to the crest of the waves by forcing some of the liquid from the second chamber or water chamber in the section concerned through the downstream non-return valve into the second chamber or water chamber in the succeeding section, regardless of whether the chambers or sections are elastically resilient as in the known tubes mentioned above or not.
• a preferred embodiment of this equipment is characterized in that each flexible chamber extends from one transverse wall to the next.
• the gas, gas mixture or air contained in the first chamber or air chamber will contribute to keeping the tube or tubes distended, for which reason it or they may be made from thin-walled material, such as plastic foil, which is comparatively cheap and easy to work with.
• Figure 1 is a sketch illustrating the principle of the invention being a longitudinal sectional view of a piece of an elongated flexible tube constituting part of an equipment according to the invention and floating on an ocean surface with waves
• Figure 2 is an example, showing how the elongated flexible tube may be constructed in practice
• Figure 3 is a sketch illustrating a process contemplated for the manufacture of the tube illustrated in Figure 2.
• the elongated tube according to the invention is shown in Figure 1 as a flexible tube with an outer wall 2.
• the space inside the tube is divided into sections , that can be imagined as designated a, b, c, ...., k, each section being separated from the neighbouring section by means of a transverse wall, the wall between sections a and b being designated as 3 ab, between sections b and c as 3bc and so forth.
• a transverse wall 3ab,3bc, etc. there is an opening with a valve flap 4ab, 4bc, etc. respectively.
• all the valve flaps 4ab-jk are adapted to open for liquid flow from left to right in the drawing and to close for liquid flow in the opposite direction.
• a corresponding pumping effect will also occur if the waves progress in the opposite direction, since what is essential for the pumping effect is the up-and-down move ment of each particular section of the flexible tube 2.
• the components shown in Figure 3 may be assembled by first cementing the transverse wall 13 together with the valve flap 4 in an oblique position in the upper part 14, after which the membranes 9 are placed against the lower faces of the lateral flanges 11' . Then, the lower part 15 is placed with its lateral flanges 11" against the lower face of those parts of the membrane 9, the upper face of which engages the lower faces of the lateral flanges 11' of the upper part 14, after which these three components are joined, such as by welding.
• the transverse wall 13 may be omitted and the upper part of the valve flap 4 used as a transverse wall, while letting the lower part of the valve flap 4 close against the lower part 15 of the tube.
