Description
Technical Field
The utility model relates to a technical field that soft body array was receive and release in marine operation refers in particular to a many arrays are supplementary to receive and release system suitable for geophysical prospecting ship.
Background
The development trend of the international geophysical prospecting ship is toward the development of multi-array and high-capacity directions, the international most advanced three-dimensional geophysical prospecting ship can be provided with 12-array and multi-group seismic source alternate operation capacity, and the number of subarrays is large. Because the number of subarrays of the three-dimensional geophysical prospecting ship is large, the number of opposite array tracks is also large, the space of a ship body needs to be fully utilized when the auxiliary winch for launching and releasing the seismic source subarrays is designed, and the operation is flexible and convenient when the auxiliary winch is launched and released, most geophysical prospecting ships are designed to share one auxiliary winch for three arrays, so that the use span of the auxiliary winch is large, the friction cable is interfered by a winch cable, the array tracks and a pulley, and the potential safety hazard of field operation is caused.
If the seismic source deck and the top floor space are quite abundant, the interference phenomenon can be reduced by designing an auxiliary winch to control 2 groups of arrays, but when the equipment swings greatly and the arrays go out of water to go up the deck in complex sea conditions, the equipment often deviates from the position below the track, and therefore the lifting cable is interfered with the equipment such as the track. Therefore, the key link of high-efficiency and safe operation of the seismic ship can be ensured when the hoisting cable and the rail corner are subjected to interference friction when the seismic source is folded and unfolded and the pulley is subjected to interference friction.
