9. A profile observation method employing the profile observation apparatus according to any one of claims 1 to 8, characterized in that the method comprises:
the winch releases the steel wire rope, the lifting unit and the anti-torsion ring are separated from the buffer cover under the action of bottom ballast, slowly sink into water, and start observation work;
when the observation work is completed, the winch recovers the steel wire rope, the lifting unit and the anti-torsion ring slowly lift the water outlet surface and are retracted into the buffer cover, the lifting unit is recovered to the water permeable well of the floating platform to be fixed, the power receiving cone at the upper end of the lifting unit compresses the power supply elastic sheet of the inner arm of the buffer cover, the circuit is connected, and the floating platform starts to charge the storage battery of the lifting unit;
and after the control module judges that the lifting unit finishes profile observation and is fixed, the wireless communication module is controlled to transmit the acquired data into a data center of the floating platform.
10. A profile observation method as claimed in claim 9, characterized in that,
when the floating platform is influenced by wind and waves to generate heave motion, the spring between the mounting cover plate and the buffer cover can be subjected to telescopic deformation, so that the transmission of the heave motion can be reduced, and the heave amplitude of the lifting unit is reduced;
when the floating platform generates swinging motion under the influence of wind and waves, one side of the spring between the mounting cover plate and the buffer cover is extruded, and the other side of the spring is stretched, so that the transmission of the swinging motion can be reduced, and the swinging amplitude of the lifting unit is reduced.
