The working principle and the working process of the invention are as follows:

fix protective housing 1 on the deck through reference column 10 and skirt angle 3, because outer loop 4, zhonghuan 5 and inner ring 6's cooperation, make the rotation that the investigation instrument can a plurality of degrees of automation, on the outside rocks and transmits the investigation instrument very little, can effectively protect the instrument, when putting in, the protective housing 1 is filled with the sea water, because the upper end is open, no matter inside dress does not adorn water and falls into all can intake in the sea, adorn water in advance and make and avoid the sea water to produce too big impact force to equipment after pouring backward. Pulling out a bolt between the skirt angle 3 and the positioning column 10 to enable the protective shell 1 to slide to the sea surface along the sliding rod 11, when the wind is calm, the protective shell 1 is connected with a winch through a cable, the sliding speed of the protective shell 1 is controlled through the winch, under extreme weather, the protective shell 1 can directly slide down along the sliding rod 11, the protective shell 1 falls into the sea and is drilled into the water, under the action of the resistance of the water, the speed of the protective shell 1 is gradually reduced, at the moment, the control valve 83 is opened to inflate the adjusting air bag 81, the adjusting air bag 81 is expanded to discharge the water in the protective shell, the buoyancy is increased to start to float upwards, and the rotating shaft of the outer ring 4 moves upwards along with the expansion of the adjusting air bag 81, so; the buoyancy adjusting structure 8 is used for two purposes, namely that the buoyancy is smaller in the water falling process, the submergence is deeper, and the deceleration process is longer, so that the water falling deceleration is more gentle, and the draft is adjusted to enable the instrument to be higher than the water surface.

When the protective shell 1 completely floats out of the water, the annular air bag 73 is controlled to deflate, the investigation instrument is completely exposed, when the protective shell is recovered, the annular air bag 73 is inflated and expanded to wrap the investigation instrument when an air pump of the annular air bag 73 is started, although the investigation instrument is retracted by controlling and adjusting the deflation of the air bag 81, the lifting lug 2 is hooked by the hook of the cable, the lifting lug 2 can be hooked by the hook by moving the sliding rod 11 in the process of hooking the lifting lug 2, in the fishing process, the gravity center of the inner ring 6 is eccentric, the larger vibration is converted into the rotation of the inner ring 6, the impact force is removed, the energy absorption motor 9 carries out energy dissipation on the rotation, and the inner ring 6.
