Abstract

A water aeration system encases an air pump and a solar power controller in an encasement structure with one or more air permeable sidewalls. The encasement structure is mounted at or near a top end of a mounting pole. A solar panel is mounted directly or indirectly to the encasement or to the mounting pole at or near the top end of the mounting pole. An air conduit is threaded through a hollow channel in the mounting pole, and then underground and/or under water for joining to an immersed diffuser. The water aeration system operates without a battery or energy accumulator, and is tamper-resistant. The air pump and controller are inside the encasement structure, the solar panel and encasement structure are mounted several feet above the ground surface, and the conduit between the pump and the diffuser is held inside the mounting pole.

Claims

1. A water aeration system, comprising:

a mounting pole defining an inner channel substantially along its length and having a top end and a bottom end, with the bottom end adapted for insertion into a ground or a footing for establishing the mounting pole upright with its top end above the ground or footing surface;

an encasement mounted at or near the top end of the mounting pole, said encasement defining an internal space, and having at least one air permeable wall;

an air pump held within the encasement;

a conduit for air pumped into the conduit by the air pump, said conduit connected at one end to the air pump and at its opposite end adapted to connect to at least one diffuser, wherein said conduit has a portion of its length positioned within the channel of the mounting pole and a portion of its length immersible in the water in which the diffuser is immersed, and wherein no portion of the length of the conduit is above ground or out of water except for the portion(s) positioned within the channel of the mounting pole or inside the encasement; and

a solar panel directly or indirectly joined to the encasement or the mounting pole such that the solar panel is at or near the top end of the mounting pole, wherein said solar panel generates power that may be converted to current for driving the air pump.

2. The water aeration system of claim 1, further comprising at least one diffuser adapted for submersion into a body of water to be aerated.

3. The water aeration system of claim 2, further comprising a controller associated with the solar panel to convert photovoltaic electrical power from the solar panel to current for driving the air pump.

4. The water aeration system of claim 2, further comprising at least one other air permeable wall opposite the air permeable wall of the encasement.

5. The water aeration system of claim 4, wherein the air permeable walls comprise a material selected from the group consisting of:

metal screen, perforated metal, expanded metal sheet, wire mesh, wire screen, coated wire mesh, coated wire screen, composite material mesh, nylon screen, moldable material mesh and moldable material screen.

6. The water aeration system of claim 2, wherein the diffuser is either a coarse bubble or a fine pore subsurface aeration diffuser.

7. The water aeration system of claim 1, wherein the encasement is mounted above a ground surface at a distance of at least about 8 feet.

8. The water aeration system of claim 3, wherein the encasement encloses the air pump and the controller inside the internal space.

9. The water aeration system of claim 2, wherein the system functions without a battery or any other energy accumulator.

10. A pole-mounted enclosure for a solar-powered water aeration system, comprising:

a mounting pole defining an inner channel substantially along its length and having a top end and a bottom end, with the bottom end adapted for insertion into a ground or a footing for establishing the mounting pole upright with its top end above the ground or footing surface;

an encasement mounted at or near the top end of the mounting pole, said encasement defining an internal space adapted for holding an air pump or source of compressed air, and having at least one air permeable wall;

a conduit for pumped air, said conduit adapted for connection to the air pump or source of compressed air at a first end and adapted for connection at its opposite end to at least one diffuser, wherein said conduit has a portion of its length positioned within the channel of the mounting pole and a portion of its length immersible in water in which the diffuser may be immersed; and

one or more brackets adapted for mounting at least one solar panel to the encasement or the mounting pole at or near the top end of the mounting pole.

11. The pole-mounted enclosure of claim 10, wherein the one or more brackets are joined to the encasement.

12. The pole-mounted enclosure of claim 10, wherein the encasement has at least two air permeable walls.

13. The pole-mounted enclosure of claim 12, wherein the air permeable walls comprise a material selected from the group consisting of:

metal screen, perforated metal, expanded metal sheet, wire mesh, wire screen, coated wire mesh, coated wire screen, composite material mesh, nylon screen, moldable material mesh and moldable material screen.

14. The pole-mounted enclosure of claim 10, wherein the mounting pole has a length of at least about 8 feet.
