Abstract
The invention discloses an underwater sound array device based on an underwater movement platform. The underwater sound array device is connected with the underwater movement platform and comprises anexternally-mounted self-contained collection bin, a multi-channel hydrophone linear array and a mounting mechanism, wherein the externally-mounted self-contained collection bin is externally mountedand fixed on the underwater movement platform through the mounting mechanism; and the externally-mounted self-contained collection bin is connected with the underwater movement platform and is furtherconnected with the multi-channel hydrophone linear array. By utilizing the underwater sound array device, when seismic exploration work is carried out in a deep sea area, the sharp attenuation of sound waves caused by great-depth sea water is avoided, the seismic exploration resolution ratio is increased, and the stratum penetration depth is increased. When the underwater sound array device is applied to hydroacoustic investigation, the underwater movement platform can be conveniently controlled to be sailed and moved to a seabed on the other position and is static again, so that the time forrecycling and rearranging an underwater sound array is saved, and the working efficiency is improved.
Description
technical field [0001] The invention relates to the technical fields of geophysical exploration and underwater acoustic survey, in particular to an underwater acoustic array device based on an underwater mobile platform. Background technique [0002] Conventional marine seismic exploration usually drags the towed array of hydrophones on the sea surface, receives the seismic waves reflected by the seabed, and further analyzes and judges the geological conditions of the seabed by calculating and drawing the acquired data. When this conventional seismic detection method works in deep-sea areas, due to the substantial attenuation of seawater to sound waves (especially high-frequency sound waves), the detection resolution and penetration depth of conventional seismic equipment for deep-sea formations are reduced. [0003] Conventional underwater acoustic surveys usually deploy one or more hydrophone arrays on the seabed by means of submerged buoys, receive acoustic signals scatte...
