Abstract

A solar water conditioning apparatus for a fishpond which includes a top container and a lower container interconnected by an elongated member. The top container is adapted for exposure to the atmosphere and the bottom container is adapted to be immersed in the fishpond. On the top of the top container is provided a device for converting solar energy into electric power which actuates a motor so as to operate an air pump to introduce fresh air into a hollow column which has its lower portion embedded in a filtering medium of the bottom container and has its upper portion extended outward from the bottom container. The apparatus not only replenishes the amount of oxygen dissolved but also filtrates some polluting material.

Claims

1. A solar water conditioning apparatus for a fishpond comprising:

a top container having an air inlet for exposure to the atmosphere;

a bottom container for being immersed in water which has a water inlet and contains a filtering material which fills a part of said lower container;

an elongated member for supporting said top container which interconnects said top and bottom containers;

means for converting solar energy into electric power provided at the top of said top container;

a motor actuated by said converting means mounted in said top container and connected to said converting means;

an air receiving hollow column provided in said lower container, said column having its lower portion embedded in said filtering material and its upper portion opened and extended outward from said lower container, said lower portion being provided with an opening for the admission of water; and

an air pump mounted in said top container and connected to said motor, said air pump having an air conduit extended into said air receiving column.

2. A solar water conditioning apparatus as claimed in claim 1, wherein said energy converting means includes a watertight casing having a top cover made of a transparent material, a photo cell disposed in said casing, and means for reflecting sunlight on said photo cell.

3. A solar water conditioning apparatus as claimed in claim 1, wherein said air pump is a reciprocating pump which has a diaphram to be reciprocated by said motor for discharging and suctioning air.

4. A solar water conditioning apparatus as claimed in claim 1, wherein said filtering material includes sand and gravel.

5. A solar water conditioning apparatus as claimed in claim 1, wherein said elongated member is a hollow member which has its top end fixedly connected to said top container and its bottom end connected to said bottom container in an upwardly or downwardly movable position.

6. A solar water conditioning apparatus as claimed in claim 1, said top container is further provided with an air filtering material at said air inlet.
