DESCRIZIONE
The invention provides a kind of for moving the buoyancy system of object in water (401).This system includes at least one inflatable body (17) and increases the buoyancy of described object (401) after the aerating device (37) inflated for described at least one inflatable body (17), the inflation of described inflatable body.Described system also includes the startup system (21) for driving described aerating device (37).When described startup system (21) starts, described aerating device (37) makes gas flow to described at least one inflatable body (17) so that described object (401) is mobile.Described aerating device can include static pressure transducer (407) and the pressure-relief valve (91,93) of the degree of depth for automatically controlling described object and position the conductor rope (411) of described object for help on the water surface.
