Definitions

  • This invention relates generally to the field of aquariums and more specifically to a solar powered aquarium.
  • Aquariums can be very simple affairs such as a glass bowl with gravel at the bottom, to very complex designs with water filters, heaters, lights and other equipment needed to keep the water environment ideal for the fish or other animals that live in it.
  • Water filtration in particular has been shown to be a most important component in the process of keeping an aquarium a healthy place for fish to live in as well as helping to maintain water clarity for optimal viewing pleasure.
  • water filters require some sort of pumping means that requires household power. This means that the table top aquarium must be connected by a pair of insulated wires to a power source. The need to plug in the filtration pump can be restrictive to where the aquarium can be placed. For example, if a person wanted to place a small aquarium on his or her desk top, it would mean that an unsightly power cord would be visible trailing across the desk to the aquarium. Additionally, many filtration pumps are somewhat noisy because traditional pumps include diaphragms or pistons that oscillate quickly and somewhat loudly.
  • the primary object of the invention is to provide a table top aquarium that has a water filtration means that does not require the user to use normal household power.
  • Another object of the invention is to provide a table top aquarium whose filtration system is relatively quiet .
  • Fig. 1 is a perspective view of a solar powered aquarium constructed in accordance with the teachings of the present invention
  • Fig. 2 is a cross-sectional side, elevational view of the solar powered aquarium.
  • Fig. 3 is an enlarged, exploded, perspective view of selected structural components of the solar powered aquarium.
  • a solar powered aquarium comprising: a water holding container suitable for use as a table top aquarium, one or more solar cells, a standard solar cell recharging circuit including one or more rechargeable batteries, said aquarium container including a secondary bottom held up from the main bottom by a side wall, a centrally located cylindrical portion mounted between said main bottom and said secondary bottom, a downwardly extending skirt located below said main bottom, a centrally located DC motor mounted below said main bottom and within said skirt, a ferrous metal plate mounted to the shaft of said DC motor, a magnetic spinning member located within said centrally located cylinder, said magnetic spinning member located in close proximity to said metal plate so that the turning of said metal plate induces the rotation of said spinning member, said recharging circuit and said rechargeable batteries located within said skirt area, and said solar cells mounted on an outside surface of said aquarium.
  • FIG. 1 we see a perspective view of the apparatus including a main water retaining vessel comprised of side wall 32 and integral base plate 52 for housing a plurality of fish or other aquatic animals or plants.
  • the vessel or container 32 is made of clear material such as glass or acrylic type plastic.
  • a centrally located secondary base late 4 is supported by side wall 48 which is in turn attached to base plate 52.
  • Side wall 48 has a plurality of notches or openings at the bottom thereof, one of which is designated by reference numeral 60 which allow passage of water therethrough.
  • Between base plate 52 and secondary base plate 4 is a small cylindrical member 6.
  • a plurality of small apertures 8 allow water to flow from the top of secondary base plate 4 into small cylinder 6.
  • Aperture 2 at the bottom of small cylinder 6 allows water to exit the cylinder 6.
  • the spinning of magnetic stirring member 20 causes a pumping action that causes water to be drawn into apertures 8 and then out through aperture 2.
  • the total area of apertures 8 is approximately equal to the area of aperture 2 so that no excess water pressure is built up within cylinder 6 thereby allowing for the smooth flow of water into and out of the cylinder 6.
  • Solar panels 28 power a small DC motor 18 located within bottom skirt 34.
  • the motor shaft terminates in a ferrous metal plate 40 as shown in the section view in Figure 2.
  • Vessel base plate 52 is relatively thin, approximately sixty thousandths of an inch, so that magnetic attractive force of magnetic stirring member 20 can be felt on the spinning metal plate 2.
  • FIG 3 shows a more detailed view of the pump mechanism.
  • Magnetic stirring member 20 is known in the chemical mixing industry as a standard method of mixing liquids within a sealed glass beaker or the like, but is not typically used as a pumping means as I have shown in the present invention.
  • the addition of a thin foam plastic layer 70 under magnetic stirrer 20 helps create a more silent spinning action so that when the present invention is placed in a quiet environment such as a person's desk, or other location, the sound of the spinning magnetic member 20 is not objectionable.
  • Standard aquarium pumps that use reciprocating pistons or diaphragms tend to produce a rather annoying buzzing noise. Referring back to Figure 2, we see that the DC motor 18 is held under the base plate 52 by support member 16.
  • Wires 22 connect the motor 18 to a charging circuit 24 that includes rechargeable batteries 26.
  • the spinning metal plate 40 can be seen just under the base plate 52 but not touching it. Because the force to rotate the magnetic spinning member 20 is so .small, motor 18 can use very little power, approximately one hundred and fifty milliamps, which can be fairly easily generated by solar panels 28 in moderate daylight. My experiments show that exposure to direct sunlight is not necessary, and that enough electrical power is stored in the rechargeable batteries 26 during the day that the motor 18 continues to spin through the night on the stored energy.
  • the pumping action caused by magnetic spinner 20 causes fish 14 related debris in the water 12 to be drawn into the gravel bed 10 where it is trapped. Periodically, the user has to exchange the debris filled gravel for new clean gravel.
  • the solar cells 28 are mounted on frictional hinges 30 so that they can be optimally adjusted to face a light source. Additionally, the solar panels can be folded to be close to the skirt for storage purposes.
  • the above described and illustrated aquarium allows a person to place the unit on a surface such as a desk or table, and to have a means to keep the water in the aquarium clean without the need to plug the unit into a standard household power source .
  • the unit is also extremely quiet so that it is not bothersome when a person is in close proximity to it for long periods of time such as when sitting at an office desk.

Abstract

L'invention concerne un aquarium solaire avec un récipient de maintien d'eau, approprié pour une utilisation en tant qu'aquarium de dessus de table et alimenté par une ou plusieurs piles solaires. Le récipient d'aquarium comprend un fond secondaire maintenu à partir du fond principal par une paroi latérale. Un petit cylindre est monté entre le fond principal et le fond secondaire. Une jupe s'étendant vers le bas reçoit un moteur en courant continu monté au-dessous du fond principal. Une plaque métallique ferreuse montée sur l'arbre du moteur en courant continu amène un élément de rotation magnétique, situé à l'intérieur du petit cylindre, à tourner. Des ouvertures dans le petit cylindre et la paroi latérale du fond secondaire permettent à l'eau d'être aspirée dans le petit cylindre et hors de la paroi latérale. Du gravier situé dans le fond du récipient piège les débris à mesure que l'eau est aspirée à travers celui-ci. Des piles solaires attachées vers l'extérieur fournissent de l'énergie pour recharger le circuit et le moteur attaché.
