Background technique

In recent years, my country's marine resources exploration and development are in full swing. A large number of marine scientific research ships have gradually moved from offshore scientific research to far sea scientific research. Underwater magnetometers for marine scientific investigations are also widely equipped on these scientific research ships. . The underwater magnetometer is used to explore underwater organisms or underwater resources. The price is relatively expensive, and the data obtained is also very precious. At present, there are generally two ways to retract and deploy the underwater magnetometer: one is to put it manually through the rear deck In the middle of the sea, when the sea conditions are poor, the underwater magnetometer is very easy to collide with the hull during launch and recovery, causing damage to the structure of the underwater magnetometer, and even damaging the survey data obtained, and some types of underwater magnetometers The weight is relatively large, and it is more difficult to manually release and recover, and it will also pose a great threat to the life safety of the operators under poor sea conditions; the other is to install a fixed lifting platform on the rear deck of the scientific research ship, but the increase The price of the early construction of the scientific research ship is reduced, and the stern fixed lifting platform that takes up a lot of space will also have an impact on other operations on the rear deck of the scientific research ship. The comprehensive consideration of the risk of collision damage to underwater magnetometers requires a retractable device for underwater magnetometers on scientific research ships that is easy to operate, highly versatile, economical, and reliable in performance.
