Abstract
An improved power source for marine applications includes a salt water acated battery adapted for actuation after a specific predetermined immersion time. The improved battery construction is characterized by an enclosed volume of flexible, plastic material confining the seawater electrodes therein. The pair of panel-like closures seal apertures in the top and bottom surface of the battery case to confine an inert liquid filling therein. A retention mechanism holds the panel-like closures in the sealed position against the urging of an actuation system urging the panels in an open position.
Claims10
A seawater activated battery for an oceanographic instrumentation package comprising:
- A plurality of lateral walls enclosing a space for positioning seawater activated electrodes;
- top and bottom panels spaced from one another and effectively sealing the top and bottom of said lateral walls such as to cooperate therewith to enclose a predetermined volume;
- aperture means in said top and bottom panels to permit fluid passage therethrough;
- closure means configured and positioned to sealably close said apertures to prevent fluid passage therethrough;
- retention means effectively connected to said closure means for holding said closure means in the sealably closed position relative to said aperture to prevent movement thereof;
- and actuation means to selectively overcome the action of said retention means for moving said closure means to a position permitting fluid flow through said apertures.
