摘要:
A method of operating a swimming pool with a circulating water flow. The method including the steps of discharging a jet of water and splitting the flow of water. The discharging step including the discharging of a jet of water from an outlet at a head end of the swimming pool into a swimming compartment, whereby the jet of water flows in a primary flow path toward a foot end of the swimming compartment. The splitting step including the splitting of the flow of water to define two circuitous flow paths, each said flow path having a return flow path flowing within said swimming compartment in a direction generally opposite to said primary flow path back toward said head end.

A bathtub comprises: a tub body (1) for accumulating bath water; a bath water treating section for activating the bath water; and a water circulating section (2) for forcedly circulating the bath water between the tub body and the bath water treating section. The bath water treating section is a magnetic water treating section (3) and/or a ceramic ball water treating section (4) to activate the bath water in a wide range.
摘要:
An apparatus for generating a stream in a body of water has at least one cylinder installed under water, and a water-jet pump housed in the cylinder. The pump draws water in through one end of the cylinder and produces a stream of water accelerated by a driving fluid supplied from an external source. The stream is discharged through another end of the cylinder to promote a flow in the body of water.
摘要:
A swim tank slightly longer than a human and slightly wider than the maximum spread between fingertips is divided into upper and lower channels by polycarbonate or members extending across the width of the tank and having a rectangular outlet at the top front through which water is expelled. A vaned wheel at the rear is driven by an induction motor from a power source of controlled frequency.

A swimming pool with a circulating water flow includes a plurality of side walls adjacent a swimming compartment, one of the side walls including an outlet, at least one inlet positioned at each lateral side of the outlet, and a plenum arrangement on a side of the one wall opposite the swimming compartment. The plenum arrangement is in communication with each inlet and the outlet. A water propulsion device is positioned within the plenum arrangement and effects a pair of circuitous water flow paths within the swimming compartment.
摘要:
A flow duct is provided in which water is caused to flow by way of a delivery device disposed in a circulation line. In order to be able to adapt the flow inside the duct to the particular requirements, and/or achieve a laminar flow over the entire flow region, a plurality of circulation lines is provided, each having a controllable delivery device, wherein the circulation lines lead into the flow duct separately from each other, and wherein the discharge openings of the circulation lines are distributed over the face wall of the flow duct.
摘要:
A portable device is provided for generating a current in a vessel having a side-wall, the vessel containing a fluid. The device includes a housing having an inlet and an outlet, and a motor attached to the housing. A propeller, driven by the motor, is positioned in the housing. A float is attached to the housing to create a buoyant force sufficient to keep the portable device afloat in the fluid. Fluid is drawn into the housing through the inlet side and forced out of the housing through the outlet side to generate the current in the vessel.
摘要:
A method and apparatus for controllably injecting high velocity jets of water at an elevation at or above water level towards a buoyant object (e.g., a boat or participant in an inner tube) that is floating in a deep water recreation attraction, and causing injected water-to-object momentum transfer and directed buoyant object movement irrespective of the motion of water upon which the buoyant object floats. Structurally, a water conduit is positioned horizontally at or near the surface of a body of water. Adjacent to this conduit is positioned, in parallel corridor like fashion, a second water conduit or a benign retaining structure. The inside width of the corridor is a distance sufficient to permit passage of the buoyant object. An array of water injectors is aligned on the inside of the conduit-formed-corridor at an elevation at or above water level. These injectors are uniformly pointed at the opposing water conduit (or benign retaining structure) at an angle to the desired direction of buoyant object travel. A water source pressurizes the conduit(s) and causes the injectors to generate a power grid of jetted water along the inside length of the corridor. Spacing between injectors and water pressure per injector is sufficient to cause a buoyant object that floats inside the corridor (e.g., a participant in an inner tube), to be propelled by each successive jet down the length of the corridor. The corridor can also be used to drive buoyant objects out of a deep-water environment and up onto a beach or other water ride attraction.
