The working mode of the satellite transmission ocean magnetic force detection device is as follows:
the sea surface equipment 1 is used for receiving magnetic force data of the total field magnetometer and the 305 submarine magnetometer 201 in real time and transmitting the received magnetic force data to a shore-based satellite receiving terminal in a satellite transmission mode; the photovoltaic power supply device 103 provides power for the sea surface satellite transceiver 101 and the sea surface data transmission device 102 through a solar panel, and transmits electric energy to the total field magnetometer and 305 submarine magnetometer 201 through an armoured cable 301.
The shore-based satellite receiving terminal receives magnetic force data sent by the satellite, and stores the magnetic force data in a file mode and displays the magnetic force data in a graphic mode.
For the transmission of power and signals, both the total field magnetometer 305 and the subsea magnetometer 201 are connected in a cabled manner with the surface installation 1. The magnetic force data detected by the total field magnetometer 305 and the submarine magnetometer 201 are transmitted to the sea surface data transmission device 102 through the armored cable, the sea surface data transmission device 102 transmits the data to the sea surface satellite receiving and transmitting device 101, the sea surface satellite receiving and transmitting device 101 automatically starts satellite data transmission after receiving the magnetic force data, and a shore-based laboratory can receive the magnetic force data in near real time.
The non-magnetic bottom anchor weight 202 is used as a protective cover, the protective cover is of a hollow structure, and the seabed magnetometer 201 is arranged in the protective cover. In the case of deployment on the sea floor, the non-magnetic bottom anchor weight 202 and the sea floor magnetometer 201 are deployed on the sea floor as a whole at the same time.
The device starts to work normally and unattended.
When the device is recovered, the acoustic releaser acts (unhooking), the nonmagnetic bottom anchor weight 202 is mechanically disengaged from the seafloor magnetometer 201, the seafloor magnetometer 201 is recovered, and the nonmagnetic bottom anchor weight 202 is left on the seafloor and is not recovered.
The submarine magnetometer 201 and the non-magnetic bottom anchor weight 202 are connected by a high strength wire (e.g., beryllium copper wire) that can withstand a tension greater than the weight of the submarine magnetometer 201 and much less than the weight of the non-magnetic bottom anchor weight 202. When the wire is laid, the weight of the seabed magnetometer 201 can be completely borne; when recovered, the wire breaks beyond the tension limit due to the need to carry several tons of weight, and the seafloor magnetometer 201 is separated from the nonmagnetic bottom anchor weight 202.
