[0034] The seabed vibration monitoring system based on offshore engineering disclosed in the present invention comprises the following steps when in use: First, the winch is connected to the lifting lug 5, and the waterproof housing 1 is slowly placed on the nearshore seabed. At this time, the positioning rod 2 is directly inserted into the soil under the action of gravity, and then the winch cable is pulled out; Then the waterproof housing 1 is fixed, and the upper computer sends a drilling instruction to the controller. The controller drives and controls the second electromagnetic lock 32 to release the lock on the drilling support disc 28. The drilling pressure spring 30 pushes the drilling support disc 28 downward, so that the lower end of the drilling rod 25 extends out of the waterproof housing 1 and inserts into the seabed. The controller then controls the drilling drive motor 21 to drive the drilling rod 25 to rotate. Under the joint action of the drilling spiral strip 26 and the drilling pressure spring 30, the drilling rod 25 continues to move downward. When the position detection switch 33 detects the drilling support disc 28, the controller stops driving the drilling drive motor 21. At this time, the drilling support disc 28 is pressed on the upper port of the inner diameter contraction section 24, so that the waterproof housing 1 is locked on the seabed. Then, the level of the two seismometers 55 is adjusted. The upper computer sends a level adjustment instruction to the controller, and the controller receives the tilt sensor 47 to detect the level of the support platform 45. The controller first drives and controls the first drive motor 36, and adjusts the level of the X-axis direction in combination with the real-time feedback of the tilt sensor 47. The controller then drives and controls the second drive motor 40, and adjusts the level of the Y-axis direction in combination with the real-time feedback of the tilt sensor 47. Finally, the level of the support platform 45 is adjusted, so that the seismometer 55 can be placed on the support platform 45 in a horizontal state. Then, the two seismometers 55 are adjusted to point north, and the upper computer sends a north-pointing adjustment instruction to the controller, which receives the north-pointing angle difference detected by the north-finder 54, and then drives and controls the rotation drive motor 51, and the four clamping support rollers 52 clamp and rotate the adjustment disk 53. Combined with the real-time feedback of the north-finder 54, when the north-finder 54 points to due north, the controller stops driving and controlling the rotation drive motor 51, and then drives and controls the clamping drive motor 46, so that the four clamping drive columns 49 are away from the seismometer 55, and the four clamping support rollers 52 are away from the adjustment disk 53, so that the seismometer 55 stays at the center of the support platform 45 without interference; Then, the seabed parameters are collected. The host computer sends a data collection instruction to the controller, the seismometer 55 collects the seabed vibration data, the hydrophone 3 collects the underwater sound signal, the accelerometer 88 collects the acceleration of the vibration, and the current meter 4 collects the speed and direction of the current. The controller collects the collected data and sends the collected data to the host computer through the data communication module and the connecting cable 87 for storage and analysis. When recovery is required, the host computer sends a recovery command to the controller, and 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 when floating up. Then the controller drives and controls the drilling drive motor 21, so that the drilling rod 25 rotates out of the seabed in the opposite direction, and then the controller drives and controls the two first electromagnetic locks 75 to release the buoyancy blocks 72 in the two release installation cylinders 71, and the two The buoyancy block 72 pulls both ends of the guide cable 79 to float to the surface of the water. After seeing the two buoyancy blocks 72, the recovery personnel of the surface vessel remove one of the buoyancy blocks 72, connect one end of the suspension cable to the removed end of the guide cable 79, and then pull the other end of the guide cable 79 upward, so that the suspension cable passes through the lifting hole of the lifting ear 5 under the pull of the guide cable 79 and then continues to be pulled upward, and finally fixes both ends of the suspension cable on the winch for suspension, and uses the winch to reel it in, so that the waterproof shell 1 finally floats to the surface of the water for recovery.
