The invention discloses a
seabed subbottom observation platform, comprising a
recovery system and a discarding support. The recovering
system comprises an integrated installation rack, a first floating ball, a second floating ball, a triad
acoustics releaser, at least one high precision
pressure sensor and at least one acoustic
distance measurement device; the first floating ball is used as a
device chamber for loading a battery, a power supply driving plate, a main control plate and an attitude sensor; the discarding support comprises a top ring rack positioned on the top and a triangle landing rack under the ring rack; each foot of the triangle landing rack is provided with a balancing weight and a
stream guidance device which are the same in specifications; and the triad
acoustics releaser, the high precision
pressure sensor and the acoustic
distance measurement device are electrically connected to the main control plate in the
device chamber. The
seabed subottom observation platform can guarantee stable sinking and landing and successful releasing and
recovery of the
recovery system, can carry out long term stable continuous observation and communication on the
seabed with the depth being smaller than 7000 meters and provides a well basis to the seabed geodetic system.
