Abstract
A method includes: a guide cable and an observation platform is provided, a profiler is mounted, and a trigger gear is set at the bottom of the guide cable; a weight drop-off gear is set at the top of the guide cable, when the observation platform is located at the top of the guide cable, one weight is released by the weight drop-off gear onto the observation platform so that the observation platform descends along the guide cable owing to additional gravity, and when the observation platform descends to the given position of the trigger gear at the bottom of the guide cable, the release gear releases the weight on the observation platform so that the observation platform returns by its own buoyancy to the top along the guide cable; another weight is subsequently released by the weight drop-off gear so that the observation platform repeats the foregoing reciprocating motion.
