[0047] When the submarine vibration monitoring system based on offshore engineering disclosed by the present invention is in use, it includes the following steps:

[0048] First, perform hoisting and lowering. Connect the winch to the lifting lug 5, and slowly place the waterproof housing 1 on the nearshore seabed. At this time, the positioning plug 2 directly inserts into the soil under the action of gravity, and then the cable of the winch is pulled away.

[0049] Then, fix the waterproof housing 1. The host computer sends a ground drilling instruction to the controller. The controller drives and controls the second electromagnetic lock 32 to release the locking of the ground drilling support disc 28. The ground drilling pressing spring 30 pushes the ground drilling support disc 28 downward, so that the lower end of the ground drilling rod 25 extends out of the waterproof housing 1 and inserts into the seabed. Then, the controller controls the ground drilling driving motor 21 to drive the ground drilling rod 25 to rotate. Under the combined action of the ground drilling spiral strip 26 and the ground drilling pressing spring 30, the ground drilling rod 25 continues to descend. When the position detection switch 33 detects the ground drilling support disc 28, the controller stops driving the ground drilling driving motor 21. At this time, the ground drilling support disc 28 presses against the upper port of the inner diameter contraction section 24, so that the waterproof housing 1 is locked on the seabed.

[0050] Then, the level adjustment of the two seismometers 55 is carried out. The host computer sends a level adjustment command to the controller. The controller receives the level of the support platform 45 detected by the inclination sensor 47. Then, the controller first drives and controls the first driving motor 36, and combines the real-time feedback of the inclination sensor 47 to adjust the level in the X-axis direction. Then, the controller drives and controls the second driving motor 40, and combines the real-time feedback of the inclination sensor 47 to adjust the level in the Y-axis direction. Finally, the level adjustment of the support platform 45 is realized, so that the seismometer 55 can be placed on the support platform 45 in a horizontal state;

[0051] Then, the north-pointing adjustment of the two seismometers 55 is carried out. The host computer sends a north-pointing adjustment command to the controller. The controller receives the north-pointing angle difference detected by the north-seeking instrument 54. Then, the controller drives and controls the rotary driving motor 51. The four clamping support rollers 52 clamp and rotate the adjustment disc 53. Combining the real-time feedback of the north-seeking instrument 54, when the north-seeking instrument 54 points to the due north, the controller stops driving and controlling the rotary driving motor 51. Then, the controller drives and controls the clamping driving motor 46, so that the four clamping driving columns 49 move away from the seismometer 55, and the four clamping support rollers 52 move away from the adjustment disc 53, so that the seismometer 55 stays at the center of the support platform 45 without interference;

[0052] Then, the seabed parameter collection is carried out. The host computer sends a data collection command to the controller. The seismometer 55 collects the seabed vibration data, the hydrophone 3 collects the underwater sound signals, the accelerometer 88 collects the acceleration of the vibration, and the current meter 4 collects the speed and direction of the sea current. Then, the controller aggregates the collected groups of data, and sends the collected data to the host computer for storage and analysis through the data communication module and the connection cable 87;

[0053] When recovery is required, the host computer sends a recovery instruction to the controller. The controller drives and controls the clamping drive motor 46 so that the four clamping support rollers 52 clamp and fix the adjustment disc 53, thereby ensuring the stability of the seismometer 55 and preventing the seismometer 55 from tilting and colliding during floating. Then, the controller drives and controls the drilling drive motor 21 so that the drill rod 25 rotates reversely out of the seabed. Next, the controller drives and controls the two first electromagnetic locks 75 to release the buoyancy blocks 72 in the two release mounting cylinders 71. The two buoyancy blocks 72 pull the two ends of the guiding cable 79 and float up to the water surface together. After the recovery personnel on the surface ship see the two buoyancy blocks 72, they remove one buoyancy block 72, connect one end of the suspension cable to the removed end of the guiding cable 79, and then pull the other end of the guiding cable 79 upward, so that the suspension cable penetrates through the suspension hole of the suspension ear 5 under the pull of the guiding cable 79 and then continues to be pulled upward. Finally, the two ends of the suspension cable are fixed on the winch for suspension, and the winch is used for winding, so that the waterproof housing 1 finally floats out of the water surface for recovery.

[0054] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as a limitation of the present invention itself. Various changes can be made in its form and details without departing from the spirit and scope of the present invention defined by the appended claims.
