when the guide body 5 and all the components of the platform base 8 are in butt joint with the ballast anchor 13 under the condition of being installed in place, the lower surface of the platform base 8 and the upper surface of the ballast anchor 13 are in a mutually close-fitting state, and for convenient and reliable assembly, the specific mode is as follows: firstly, the earring on the adjustable earring 9, which is contacted with the release rope 6, is firstly adjusted to a position on the ballast anchor 13, which is close to the disc-shaped structure, an operation space enough for connecting the release rope 6 with the acoustic releaser 3 is reserved, after the release rope 6 and the acoustic releaser are connected, a screw rod or a screw sleeve of the adjustable earring 9 is rotated, and the height of the adjustable earring 9 is adjusted, so that the platform base 8 and the ballast anchor 13 are fixedly connected into a whole.

Example 2:

because the base-type observation platform is heavy and carries more precise submarine observation equipment, and works underwater in a marine environment, the environment is quite severe, and in order to ensure that equipment is prevented from being damaged in a working stage and ensure personnel safety, the embodiment provides a layout recovery method of the base-type observation platform on the basis of the embodiment 1, and the method comprises the following specific steps of:

step one, a preparation stage:

step 1-1, regulating the ship speed to be less than 3 knots, and sailing in countercurrent;

step 1-2, connecting the laying rope 12 with a mechanical releaser for laying, and connecting the mechanical releaser with a lifting hook on a shipborne cantilever crane;

step 1-3, slowly starting a shipborne cantilever crane, hanging a seat-bottom type observation platform through a hanging hook, a mechanical releaser and a laying rope 12, and placing the seat-bottom type observation platform on a platform placing frame when the seat-bottom type observation platform leaves the ground, wherein a ballast anchor 13 faces upwards;

step two, a laying stage:

step 2-4, after the base-type observation platform enters the sea, as the ballast anchor 13 faces upwards, the floating center of the base-type observation platform faces downwards, the gravity center of the base-type observation platform is upwards, and the base-type observation platform naturally turns over, so that the ballast anchor 13 faces downwards and sinks;

by adopting the laying process, a special hoisting tool is not needed; secondly, in the laying process, no sea condition is recognized, and the equipment is not damaged when the equipment is laid by the laying rope 12; thirdly, as the ballast anchor 13 faces upwards, the floating center of the base type observation platform is arranged downwards, and the gravity center is arranged upwards, and the base type observation platform can naturally turn over and sink after being immersed in water.

Step three, working and recycling stage:

step 3-1, after the base type observation platform reaches the seabed, the mother ship control unit sends a spreading instruction to the acoustic releaser 3, the acoustic releaser 3 receives the spreading instruction and then transmits the spreading instruction to the control unit in the main control cabin 2, the control unit sends a cable spreading mechanism 7, the cable spreading mechanism 7 acts after receiving the cable spreading instruction, the cable spreading mechanism 7 is disconnected from the connection of the cable spreading mechanism 7 and the rope, and the cable is ejected and spread outside the guide body 2; the sensor of the unfolded cable is positioned outside the current carrier body 2, acquires ocean monitoring data outside the current carrier body 2 and transmits the ocean monitoring data to the control unit in the main control cabin 2; meanwhile, the control unit in the main control cabin 2 transmits the received ocean monitoring data to the communication buoy 4;

Step 3-2, after the observed set time is reached, the mother ship control unit sends an instruction for releasing the communication buoy 4 to the acoustic releaser 3, the acoustic releaser 3 receives the instruction for releasing the communication buoy 4 and then transmits the instruction to the control unit in the main control cabin 2, the control unit sends the instruction for releasing the communication buoy 4 to any one of the motor release devices 11, the motor release devices 11 work after receiving the instruction for releasing the communication buoy 4, the corresponding communication buoy 4 is pushed to separate from the current carrier 5, the communication buoy 4 rises to the water surface under the action of the own buoyancy, and the collected ocean monitoring data is transmitted to the shore-based control unit or the mother ship control unit;

step 3-3, repeating step 3-2 until after all communication buoys 4 are released, the mother ship control unit sends a recovery instruction to the acoustic releasers 3, the acoustic releasers 3 receive the recovery instruction and then transmit the recovery instruction to the control unit in the main control cabin 2, the control unit controls the connection parts of the two acoustic releasers 3 to be opened, the acoustic releasers 3 are disconnected from the release rope 6, the connection between the platform base 8 and the ballast anchor 13 is released, and the platform assembly and the seafloor observation equipment carried by the platform assembly are lifted to the water surface under the action of the buoyancy of the diversion body 5;
