Submersible life support device for aquatic ecosystems
Light, heat, gas exchange, and water motion are all required elements to sustain aquatic photosynthetic organisms. Rather than providing separate systems, a flux of photons appropriate for photosynthetic organisms, including algae, is dispersed throughout the surrounding water. A gas source performs water movement and circulation by acting as an airlift pump while performing a liquid-gas mass transfer. Finally, heat is added to the surrounding liquid by a heat source or the light source, which increases the rate at which microorganisms grow and improve efficiencies. By combining these necessary components for aquatic life support, efficiencies are increased, costs are saved, and photosynthetic organism growth is regulated.
1. A fully submergible aquatic life support device, comprising:
a body having an inlet in fluid communication with an outlet by way of a hollow passageway coupled in between and extending through the body, the inlet and the outlet being open to an exterior thereby permitting fluid to move into the body through the inlet, through the hollow passageway, and out from the body through the outlet when the life support device is submerged;
a waterproof fitting coupled with the inlet for selectively receiving and injecting a pressurized fluid into the interior of the hollow passageway;
a light transmitting cover coupled with the inlet and the outlet forming a waterproof enclosure about the hollow passageway and wrapped around an exterior of the hollow passageway; and
a light source within the waterproof enclosure positioned to emit light out through the light transmitting cover and into a fluid medium when the life support device is submerged.
2. The device of claim 1 , wherein the inlet further includes a plurality of waterproof fittings.
3. The device of claim 1 , wherein the inlet further includes a plurality of waterproof attachment points.
4. The device of claim 1 , including a heat source positioned within the waterproof enclosure to emit heat out through the cover and into the fluid medium when the life support device is submerged.
5. The device of claim 4 , wherein the heat source comprises a convection heater.
6. The device of claim 1 , wherein the light source comprises a wavelength of 400 nM to 700 nM.
7. The device of claim 1 , wherein the light source comprises LED lights.
8. The device of claim 2 , including a gas source comprising a gas diffuser selectively coupled to one of the plurality of waterproof fittings.
9. The device of claim 8 , including a control box in communication with the light source, the gas source, and a power supply.
10. The device of claim 1 , including a stand selectively couplable to the life support device to position the body at an angle.
11. The device of claim 1 , including a plurality of the life support devices coupled with one another via a network or a physical attachment.
12. The device of claim 1 , including an air hose connected to the inlet in waterproof relation therewith.
