摘要： A wave-powered pumping device for location in a body of water is described. The pumping device includes a submersible cylinder to be anchored to the bed of the body of water, the cylinder defining a bore. An underwater float acts on the cylinder and is arranged to urge the cylinder into an upright orientation in the water. A surface float is arranged to float at, or close enough to, the surface of the body of water in use to move up and down in the body of water in accordance with wave movement and tidal movement. An elongate member depends from the surface float. The elongate member extends telescopically into the bore of the submersible cylinder to define a pumping chamber within the cylinder. The volume of the pumping chamber varies with wave movement in a pumping cycle to draw fluid into the pumping chamber on an upstroke of the elongate member and to pump fluid out of the pumping chamber on a downstroke of the elongate member. The length of the pumping chamber varies with tidal movement to adjust to changing tidal depth by extending or retracting the elongate member relative to the cylinder while effective pumping cycles continue across a tidal range without needing to move the cylinder with respect to the bed of the body of water. To the extent that the elongate member is retracted into the bore of the cylinder, the elongate member occupies a majority of the cross-sectional area of the bore.

摘要翻译：描述了用于在水体中定位的波浪式泵送装置。泵送装置包括将被锚固到水体的床的潜水筒，缸体限定孔。水下浮子作用在气缸上，并被布置成将气缸推向水中的竖直取向。表面浮子布置成在水体的表面上浮动或足够靠近，使其在水体中根据波浪运动和潮汐运动而上下移动。细长构件从表面浮起。细长构件可伸缩地延伸到潜水筒的孔中以在气缸内限定泵送室。泵送室的体积随着抽吸循环中的波浪运动而变化，以在细长构件的上行牵引下将流体抽吸到泵送室中，并且在长条构件的下行程序上将流体泵出泵送室。泵送室的长度随着潮汐运动而变化，以通过相对于气缸延伸或缩回细长构件来适应潮汐变化的变化，同时有效的泵送循环在潮汐范围内持续，而不需要相对于主体床移动气缸的水。在细长构件缩回到圆筒的孔中的程度上，细长构件占据孔的横截面积的大部分。

摘要： A Self Priming Gravity Wave Water Pump, Double Acting, vertically Self Adjusting incorporating a Submerged Column Platform as shown in Figure 4A, the submerged column platform (22) can be tethered (28) or secured by a pivot to a weight (29) or fixed into the water bed (31). The column (22) can be incorporated into an additional submerged water filled column chamber (23), to operate as a hydraulic tidal adjustable column platform. The Gravity Wave Pump (9) is a wave energy converter using wave energy in the form of wave motion to displace a float (2), to lift the pumps reciprocating piston (12) and uses gravity, causing a weight (3) to push a piston down as the wave passes. The pump could pressurise piped water to a head of up to 100 metres or more and could pump pressures in excess of 150 pounds per square inch when adjusted accordingly.
