Patent ID: 7722290

Claim:
A transportable module for use in generating waves in a body of water, the module capable of being delivered to a desired location by a road vehicle, said module comprising; a subunit comprising at least one rigid tubular chamber and at least one rigid ballast tank, wherein: the at least one tubular chamber has a predetermined length, a rear check valve located at the rear end to permit flow into the chamber and substantially block flow out of the chamber, and a gas port proximate to the rear end for the admission of compressed gas into the chamber, the at least one ballast tank is mounted superposed above the tubular chamber and has dimensions similar to the tubular chamber and a volume substantially equal to or greater than the volume of the tubular chamber, and at least one ballast water port for the admission and removal of ballast water; the chamber and ballast tank are integrated together to form an outer surface having a bottom, two sides, and a top; a connecting system mounted on the outer surface of the subunit by which the module may be detachably connected in parallel to other such modules in a side to side manner; a transport mount on the outer surface of the subunit capable of detachably mating to a wheeled transport unit to support a trailing end of the module when transported by the road vehicle; a coupling member affixed to the outer surface of the subunit positioned on the subunit end opposite the trailing end and capable of detachably coupling to a tow point on the road vehicle, by which the module may be towed when the transport mount is coupled to a wheeled unit; wherein the module is capable of being transported to a body of water by the road vehicle, detached from the road vehicle and wheeled transport unit, transferred to a body of water, situated within a body of water at a desired location in a substantially horizontal orientation with the front and rear ends of the chamber in fluid communication with the body of water, oriented to discharge in a desired direction, the ballast tank may be filled by the admission of water in order to restrain the module in a desired location, and an admission of compressed gas into the rear end of the chamber expels water out of the front end of the chamber generating a wave in the body of water.
