Single cabin balls combined wideband OBS

The present invention discloses a single-compartment ball combined broadband OBS, relates to seismic technology for seafloor seismic natural. Including functional cabin, seismometer cabin, sink and decoupling mechanism coupled frame. The decoupling mechanism is fixed in the functional compartment plastic top housing coupled with the sink are connected by wire tensioning frame corrosion, when the instrument is recovered, the principle of the fuse wire by electrolytic corrosion, and seismometers function cabin compartment NATURAL floating recovered. The present invention employs coupling seismometer in direct contact with the seabed, to optimize the performance of the coupling, reduces the level of signal distortion due to the water caused by surging; undersea seismic purpose can be achieved. Compared with similar products abroad multi-compartment ball, structure significantly different, there are significant advantages in weight, size and cost.
