The invention discloses an anti-trawl
seabed base of an
ocean bottom seismograph. The anti-trawl
seabed base of the
ocean bottom seismograph comprises placing devices, an OBS, a sinking
coupling frame, a floating body cabin, a floating body, an acoustic releaser, a recycling
rope cabin, a recycling
rope, a main cabin, a square vertical shaft, an outer cover of an octagonal prismaid shape and a bottom-sitting frame. The main points are that the main cabin is formed by corresponding connection of the bottom of the outer cover of the octagonal prismaid shape and the bottom-sitting frame, the recycling
rope cabin, the placing devices and the square vertical shaft are fixed on the bottom-sitting frame, the square vertical shaft and the recycling rope cabin are arranged at the center and one side of the main cabin respectively, the acoustic releaser is fixed in the center of the floating body, the floating body is arranged in the floating body cabin on the top of the recycling rope cabin, and the recycling rope connected with the floating body is connected with the recycling rope cabin. The sinking
coupling frame that fixes the OBS is fixed in the center of the square vertical shaft, and is connected with side edge U-shaped rings of the placing devices through flexible connecting devices. The anti-trawl
seabed base of the
ocean bottom seismograph has the advantages of having high
system security, can
resist movement and
impact damage of operation of a trawler, and satisfies the requirements for long-term, fixed point, continuous, and automatic monitoring in severe environment.
