| 摘要 |
<p>Disclosed herein is an underwater air supply apparatus that is capable of generating air bubbles into a water tank using kinetic energy created during the discharge of water from the water tank. The underwater air supply apparatus includes an air bubble generating unit, mounted in a water discharge part of the water tank, below which a space part is defined for introducing external air into a water tank, during the discharge of water from the water tank. The underwater air supply apparatus further includes an electricity generating unit mounted in the water tank for converting potential energy of air bubbles rising in the water tank into kinetic energy to generate electricity.</p> |
