Claim Text:
1. An along-the-cable reciprocating motion control mechanism, the control mechanism comprising: a moving platform, a weight drop-off gear, a weight release gear and a trigger gear, the moving platform is attached to a guide cable and is configured to make a reciprocating motion along the guide cable, a profiler is carried by the moving platform and a buoyancy of the moving platform carrying the profiler is greater than zero, the weight drop-off gear is set at a top of the guide cable and is configured to drop a weight onto the moving platform within a predefined period, the weight release gear is set on the moving platform, the trigger gear is set at a bottom of the guide cable, and when the moving platform carries a weight and descends to the bottom of the guide cable, the trigger gear touches the weight release gear to enable it to act accordingly, thus causing the weight to separate from the moving platform, and the moving platform ascends by its own buoyancy to the top of the guide cable.
