And then all the upper pulling ropes 123 and the lower pulling ropes 124 are fixed at corresponding positions on the frame 111 according to the connection rule. The upper tow rope 123 of the first winch 1212 is then released, thereby releasing the equipment deployment unit 11 into the water in the net cage 20.

If the laying unit 11 needs to be further installed to the central position of the net cage 20, the upper hauling rope 123 of the winch 121 No. 2 can be continuously released to the length of the required position; then retracting the upper hauling ropes 123 of the winches 121 No. 1, No. 3 and No. 4 to the required position length; finally, the lower hauling cable 124 of the winch 121 No. 1, No. 3 and No. 4 is withdrawn to the required position.

In actual operation, when the offset angle measured by the first sensor 112 is greater than 15 °, the measured angle data, and the corresponding yaw direction, are provided to the controller. The controller determines which winch 121 is used for winding and unwinding the cable according to the direction, and determines the amount of the cable to be wound and unwound according to the size of the deflection angle.

Taking as an example the direction in which the laying unit 11 is biased towards the winch 121 No. 4 under the influence of the water flow: and under the condition of keeping the rope field of other winches 121 unchanged, the No. 4 winch 121 releases the lower hauling rope 124 under the control of the controller, and the No. 1 winch 121 recovers the lower hauling rope 124.

If the direction is not positive to one of the winches 121, the direction is decomposed, and then the length of the cable wound and unwound by each winch 121 is determined. In order to control the variable and facilitate adjustment, the adjustment of the posture of the laying unit 11 is completed by winding and unwinding the lower hauling rope 124 by the winches 121 No. 1, No. 2, No. 3 and No. 4. According to the method, the system can be dynamically adjusted to the arrangement unit 11 within 15 degrees, so that the requirements of most underwater monitoring equipment are met.

For the adjustment of the attitude within 15 degrees, the controller controls the first adjusting motor 1181 and the second adjusting motor 1182 according to the motion data monitored by the second sensor 114, and compensates the included angle between the servo platform 115 and the ground through the matching rotation of the first connecting shaft 1161 and the second connecting shaft 1171, so that the adjustment precision of the underwater position of the detection device is further improved on the basis of the adjustment of the position of the frame 111.
