Edge is fixed on the housing.
9. a kind of seabed ground sound communication system, which is characterized in that including multiple described in any item seabeds claim 1-8 sound
Communication device, multiple seabeds sound communication device is spaced apart is mounted on seabed different location, in which:
Ground sound communication device in seabed at first position, when local communications platform be detected with submarine or ROV close to when, work is referred to
It enables by the way that after compiling encryption, the signal generating unit being sent at the first position, signal generating unit works at this, and
By vibration information with being transmitted at second seabed sound communication device；
Second place seabed sound communication device signal detection unit with receiving at first position seabed sound communication device
Information, send information to the local communication platform of the second place, which will send out after information decryption processing
The acceptance subject of the second place is given, so that knowing at first position has submarine or ROV invasion information；
From second place seabed sound communication device to seabed from first position sound communication device send information also use it is upper
Identical mode is stated, in this way, realize the secrecy transmission of more ground information.
10. a kind of described in any item seabeds claim 1-8 sound communication device installation method characterized by comprising
Water pipe one end on shell is connected with high-pressure plunger pump, starts high-pressure plunger pump；Water pipe is protruded into from the cover top portion
In the shell and it is connected to cavity, the access of the water pipe, the cavity and keyhole formation sealing；
The high pressure water flow projected from the aperture of the shell can impact and fluidize the seabed silt of outer casing bottom, with promoting seabed
Sound communication system is sunk；When shell sinks down into designated position, turn off high-pressure plunger pump；
Alternatively, being further provided with vibration unit below shell, the vibration unit and the shell are fixed together, and pass through
Vibration frequency is adjusted, and then accelerates silt fluidisation around undersea system device, device is made to sink to specified basement rock with fast speed
Layer.
