SELF-FLOATING SEAFLOOR HEAT FLOW LONG-TERM OBSERVATION STATION

摘要

A self-floating seafloor heat flow long-term observation station comprises a recycling unit (1), a discarding unit (2) and a cable cutting mechanism (3). The recycling unit (1) is provided with a recycling support, the recycling support is internally provided with two acoustic release transponders (13), the bottoms of the acoustic release transponders (13) are provided with hooks capable of being closed (131), and the recycling support is provided with floating balls (14) in a carrying mode. The discarding unit (2) is provided with a discarding support, and a heat flow probe (24) is fixedly connected below the discarding support. The recycling unit (1) and the discarding unit (2) are fixed together through steel wire ropes (4) of which the two ends are connected with the hooks capable of being closed and arranged at the bottoms of the acoustic release transponders (13). The cable cutting mechanism (3) is fixed to the bottom of the recycling support of the recycling unit (1) and is connected with the steel wire ropes (4) through the movable hooks. Cables (0) start off from the discarding unit (2), then enter the cable cutting mechanism (3), and then penetrate out of the cable cutting mechanism (3) and are connected with the floating balls (14) of the recycling unit (1). The cable cutting mechanism (3) is started to cut off the cables through change of the steel wire ropes (4) from tension to loosening. By means of the base station, the cables can be automatically cut off and/or unplugged, the separation of the recycling unit from the discarding unit is easily achieved, and the base station is suitable for seafloor long-term heat flow observation.
