Definitions

  • Embodiments of the invention relate generally to equipment and methods of generating electricity as a consequence of fluid flow and more particularly, although not necessarily exclusively, to generating electricity as a result of water flow for purposes including (but not limited to) ceasing operation of automatic swimming pool cleaners (APCs), powering gas heaters, debris traps, flow measurements, or flow displays, and activating light-emitting diodes (LEDs) or other lighting positioned in return lines or other areas of pools or spas, or any other electrical components associated with a pool or spa or other water feature that may be powered by an amount of energy created by converting flowing water into electrical energy.
  • APCs automatic swimming pool cleaners
  • LEDs light-emitting diodes
  • Pool- related (or other) gas heaters likewise may be powered by electricity, as may various valves and other devices.
  • these devices when present, typically are powered by batteries, electrical mains, standing pilot thermopiles, or solar energy. They hence do not exploit the fact that standard filtration systems of pools and spas recirculate water, with the fluid movement providing the potential of a source of energy for electrical generation.
  • a housing may define both primary and secondary flow paths for fluid, with the secondary path including an electricity-generating mechanism comprising a turbine and a generator.
  • Generated electricity may, for example, power a salt-water chlorinator (SWC) positioned in the primary fluid flow path.
  • SWC salt-water chlorinator
  • U.S. Patent Application Serial No. 13/049,029 (the “'029 Application”), entitled “Idler Mechanisms for Hydraulic Devices,” describes systems and methods for idling a hydraulic pool cleaner and inhibiting its movement.
  • One way this can be done is by creating a by-pass port that can pass water therethrough when open (via action of the pool pump). This diverts water from the primary flow path (and consequently reduces fluid flow through the primary flow path) such that the fluid drawn through the pool cleaner primary flow path is at a level below an operational level, preventing movement of the pool cleaner (i.e., allowing it to idle).
  • the by-pass port is closed, the action of the pool pump causes the pool cleaner to operate and move along the pool floor in a normal fashion.
  • U.S. Patent No. 7,036,951 entitled “Swimming Pool Steps with Light,” describes a system that uses a generator to provide electric current to power low voltage lights that are positioned on stairs/risers of an above-ground pool. It is intended to provide assistance by illuminating the area around the steps or to alert a user that someone has entered the pool.
  • the generator is mounted on an output conduit.
  • Embodiments of the present invention provide devices for generating electricity as a consequence of fluid flow.
  • the generated electricity may be used to operate a valve. This fluid flow may then be used to generate electricity for other pool equipment or small items.
  • the generated electricity may be used to power any number of pool or spa-related items that require electricity in order to operate, such as a gas heater ignition, pool lights, or any other equipment or items.
  • At least one version of the invention includes a housing defining primary and secondary flow paths, such that a secondary flow path has a turbine generator positioned therein. Fluid flowing through the secondary flow path operates the turbine generator so as to generate electricity.
  • the electricity in turn, my be used to operate a latch actuator that periodically opens a door or other valve.
  • the generator may be positioned along a water return or flow line, such that it can generate electricity for other pool or spa components.
  • the generator may be positioned on, near, within or otherwise in close proximity to a fluid tubing or a water line leading to a gas powered heater, such that the system can generate electricity to activate the heater unit.
  • the generator may be positioned on, within or otherwise in close proximity to a water return fitting or other pool fitting leading to the pool or spa, such that it can generate electricity for an LED light or other pool or spa components, based on water flow therethrough.
  • a water return fitting or other pool fitting leading to the pool or spa such that it can generate electricity for an LED light or other pool or spa components, based on water flow therethrough.

  • Certain features of the invention provide a system and method for diverting water flow in order to generate electricity for equipment items and apparatus associated with swimming pools, hot tubs, and/or spas that require low-amperage electricity for operation. Other features relate to a system and method for securing a generator at or near a position at which low-amperage electricity will be used in the swimming pool or spa.
  • some swimming pools and spas include decorative and functional lighting powered by electricity (such as lighting for water features or landscaping), gas- powered heaters that are powered on by electrical ignition or other electrical power, debris collectors, skimmers, water misters, water features or fountains, clocks, timers, water flow meters, small pool toys, pool cleaners or components within such cleaners, electronic water level systems, and any other number of items that use low amounts of electrical power that can be generated by the methods described herein.
  • a turbine or other water powered generator may be positioned at or near a gas powered heater in order to provide ignition energy for the heater.
  • the generator may be positioned at or near a pool fitting that contains or houses a light or other electric component in order to provide energy for the light or other electric component.
  • FIGS. 1 and 2 illustrate an exemplary device 10, showing a bypass valve for diverting fluid flow.
  • device 10 is configured for attachment in-line to hoses, pipes, pool or spa fittings, or other conduits for fluid.
  • Device 10 thus includes inlet 14 and outlet 18, with inlet 14 typically (although not necessarily) being connected via hose to an APC and outlet 18 typically (although again not necessarily) being connected via hose to an inlet of a pump.
  • Device 10 may be external to both an APC and a hose, facilitating its use for retrofitting existing systems. Alternatively, however, device 10 may be incorporated into either or both of the APC or the hose. Yet alternatively, device 10 may be incorporated into or connected to any of a weir, skimmer, suction or pressure line, or otherwise as appropriate or desired.
  • housing 22 Also included as part of device 10 is housing 22.
  • the housing 22 may be made of any suitable material and comprise any number of components; preferably, however, housing 22 is molded of plastic material into a single unit.
  • Connected to housing 22 may be a by pass valve, opening, or door 26.
  • door 26 When door 26 is closed (as shown in FIGS. 1-3), fluid enters and exits device 10 only through inlet 14 and outlet 18.
  • device 10 is essentially merely a continuation of the hose or cleaner, and water flowing from inlet 14 to outlet 18 may pass through mechanism 10 unabated.
  • door 26 is open (as shown in FIG. 4)
  • Fluid may enter device 10 also through the door 26 rather than (or in addition to) inlet and outlets of the device 10.
  • Door 26 thus functions as a by-pass port when open. When door 26 is opened, the pump will draw most (if not all) of its water directly from the pool, bypassing the body of the APC. This is illustrated by FIGS. 3 and 4 and outlined more
  • FIG. 3 illustrates exemplary flow through device 10 when door 26 is closed.
  • fluid e.g. water
  • first pathway 46 preferably is tubular and not substantially more restrictive to flow than are the hoses to which device 10 is attached. Accordingly, first pathway 46 forms a generally unobstructed routing from inlet 14 to outlet 18 and thus comprises part of the primary flow path PFP through device 10.
  • Secondary flow path SFP also exists within device 10.
  • device 10 accepts a fraction of the fluid flowing through inlet 14 into secondary flow path SFP via filter 50 and secondary inlet 54. This fraction of diverted fluid then encounters a turbine generator 30 (which is described in more detail below).
  • generator 30 may be positioned within a device 10, typically at a point between inlet 14 and outlet 18.
  • a fraction of diverted fluid that flows along SFP encounters the generator 30, causing generator 30 to produce electricity.
  • Electricity generated by generator 30 may operate (electric) actuator 38 so as to rotate valve latch 34.
  • latch 34 either allows door 26 to pivot (and thus open) under influence of a pump, as shown in FIG.
  • second pathway 62 is more restrictive of fluid flow than is first pathway 46.
  • bypass inlet 66 When door 26 is open, as shown in FIG. 4, fluid may enter device 10 via bypass inlet 66. Such fluid may then travel generally unobstructed through secondary outlet 58 to outlet 18, thus in a bypass flow path BFP. Because the bypass flow path BFP is generally unobstructed and of shorter distance than is primary flow path PFP, the majority of fluid entering device 10 will do so via bypass inlet 66, thus reducing the draw of fluid through inlet 14. This reduced draw in turn reduces fluid drawn into a connected APC, preferably to below a level at which it is operational. This keeps the APC in an idle mode, while still allowing fluid flow through the unit. In this instance, fluid flow through the body will be insufficient to create any substantial movement of the cleaner.
  • valve when the valve is placed between an APC and the inlet of a pump, it may be used to divert water directly to the pump, rather than through the APC. Stated differently, allowing a generally unobstructed flow path from the pool or spa to a pump will reduce the suction force available to draw pool water through the APC, effectively ceasing its operation.
  • Turbine generator 30 generally includes a water turbine which will be rotated by the water recirculating system of the pool or spa, such that movement of the water causes generation of an electric current or power.
  • Generator 30 may be any suitable such device, including those turbine-driven generators discussed in the ⁇ 83 Application.
  • One acceptable version of generator 30 is a commercially-available device used to illuminate LEDs in a shower head.
  • a generator 30 is a micro-hydro turbine generator, a paddle generator (which uses a paddle instead of a turbine), or any other generator that is of a size to be positioned within a hose, a pool fitting, water conduit, fluid tubing, or other pool equipment and that can use water flow for energy generation.
  • one potential generator system that may be used with the
  • FIGS. 5A and 5B This generator 30 may be a modified component from a shower head that generates energy for LED lights in the shower head.
  • generator 30 may comprise a rotor 70, a rotor shaft 72, two coil housings 74, a stator 76, and a stator housing 78.
  • the rotor 70 is assembled between two coil housings, and coil wires may be injection molded into the coil housings 74.
  • generator 30 may positioned within an element 80, which can then be associated with a pool tubing, hose, fluid tubing or conduit, or any such type of pool tubing, PVC tubing, tubing delivering water to a gas heater, tubing delivering water to an intake valve of the pool, a water hose, fluid tubing, or any other type of water flow conduit.
  • element 80 has generator 30 positioned therein.
  • Element 80 may have a clam-shell type configuration, which allows it to be associated in-line with existing pool or fluid tubing in a retro-fit fashion.
  • top portion 79 and bottom portion 81 may be provided separate from one another.
  • One or more holes may be drilled in the existing pool or fluid tubing and one or more internal opening portions 83 may be positioned within or aligned in such holes. This allows water flowing through the fluid tubing to also flow through element 80. Portions 79 and 81 are then secured to one another in a water-tight fashion. At this point, water flowing through pool tubing also flows through element 80, activating generator system 30 positioned therein. In other words, a substantial portion of the fluid flowing through element 80 interacts with and generates energy in cooperation with generator 30 that is positioned within element 80, causing generator 30 to produce electricity. In this way, the generator 30 is incorporated in-line with the fluid tubing leading from the pump of the water recirculating system. Electricity generated by generator 30 may be stored and used in any number of ways.
  • this system may be used as a water meter or a water flow meter, because activation of generator can indicate how fast water is flowing through the pool tubing. The stronger the water is flowing, the faster the generator turns. This would allow a user to infer water flow based on the electrical output of the generator.
  • the electricity generated is used to power on a gas powered heater unit.
  • turbine generator 30 may be provided in a tubing pod 82 that is designed to house the generator 30.
  • This design makes it possible to add the generator 30 to existing systems by simply removing a piece of pool or spa tubing and replacing it with the tubing pod 82.
  • a turbine power cord 84 may be used to harness and direct the energy created.
  • FIG. 8 shows tubing pod 82 positioned outside a gas powered generator 86 for ease of illustration, but it should be understood that tubing pod 82 or element 80 may be positioned within or in closer proximity to the heater 86. In an ideal implementation that is designed to deliver electricity to a gas powered heater, the system 80 or 82 may be integrated into the gas powered heater unit.
  • FIG. 8 shows an example of a turbine power cord 84 delivering the energy created to a gas powered heater 86 for use in connection with a pool system in order to deliver the power appropriately.
  • This cord may be substantially shorter if the system is fully integrated.

  • the inventor has provided an alternate solution.
  • the current design uses the flow of water to generate electricity for powering on a gas powered heater, eliminating the need for a high voltage or other electrical connection. Accordingly, one of the benefits of harnessing power from water flowing through a pool system in this manner is that it is inherently safe— there is not any high voltage electricity to contend with. It is also self- powered, such that no external power source or AC power cord is needed. It is easy to install, without an electrician.
