Abstract
The present invention consist of an improved and very compact hand held pool debris removal system using a hydrodynamic water circulation device capable of producing significant water flow through a conduit. Such water flow is then used to lift and convey debris from bodies of water such as fountains, ponds and swimming pools. The device operates by creating a high speed water jet curtain using an external source of energy by means of pressurized water, which impinges on an steady body of water transforming the energy provided by the external water source into a strong flow capable of lifting and conveying light and heavy debris from the floor of bodies of water and forcing these debris into a fine mesh filter for retention and later disposal.
Claims19
A pool debris retrieving device comprising:
- a high speed water jet curtain generating device;
- a debris collecting filter;
- said high speed water jet curtain generating device powered by an external source of high pressure water, wherein said high speed water jet curtain generating device induces a stream of water mixed with debris through a conduit;
- said conduit having an inlet opening and an outlet opening;
- said conduit having disposed within the internal wall a continuous peripheral nozzle in fluid communication with a high pressure water reservoir;
- said stream of water mixed with debris exits said conduit through said outlet opening, into said debris collecting filter;
- said debris collecting filter being a water permeable container.
A waterborne debris removing device comprised by:
- a water inducing conduit;
- a debris collecting filter;
- said conduit having an inlet opening and an outlet opening;
- disposed within the internal wall of said conduit, is a closed loop continuous nozzle;
- said closed loop continuous nozzle to discharge a high speed water curtain into the internal periphery of said conduit in the direction of said outlet nozzle;
- wherein said high speed water jet curtain induces a stream of water through said conduit when it is submerged into a body of water.
A water induction system comprised by:
- a conduit;
- a peripheral continuous nozzle;
- a high pressure reservoir;
- said conduit having an inlet opening, internal walls and an outlet opening;
- said peripheral continuous nozzle disposed within said conduit internal wall;
- said high pressure reservoir to evenly distribute a flow of pressurized water around said peripheral continuous nozzle;
- said peripheral continuous nozzle delimited by two walls;
- a first wall being a truncated conical surface with an angular inclination in the direction of said conduit outlet opening;
- a second wall substantially concentric to said first wall;
- said second wall being a truncated conical surface with an angular inclination in the direction of said outlet opening;
- said first and second walls forming a circumferential cavity;
- said circumferential cavity delimited by said conduit internal wall and said high pressure reservoir;
- wherein said intersection of said truncated conical walls with said conduit internal wall creates said peripheral continuous nozzle which transforms said external pressurized flow of water into a high speed water jet curtain within the internal volume of said conduit;
- said high speed water jet curtain to impinge into a steady body of water creating an induced water flow through said conduit internal volume.
