<p>The present invention relates to a lifesaving device on the water, which comprises a compressed gas tank which stores compressed gas; a guide line which guides a moving route of the compressed gas discharged from the compressed gas tank; a safety valve which is installed on one point in a longitudinal direction of the guide line and opens the closed moving route of the compressed gas by a temporary fixing member which is melted when coming contact with water while maintaining a closed state of the moving route of the compressed gas; and an expansion tube which is expanded by the compressed gas passing through the guide line. Accordingly, the lifesaving device on the water is thrown a long distance to a rescuee who faces a drowning accident, and is capable of quickly expanding the expansion tube, since gas is generated by chemical reaction when the gas comes in contact with water and is automatically injected into the tube.</p> |
