Abstract
The invention relates to a horizontal mooring marine environmental noise vector field monitoring subsurface buoy platform, which belongs to the field of marine environmental monitoring equipment. The platform comprises a main floating body, hydraulic safe suspension devices, a vector hydrophone, an instrument cabin and a trifurcate mooring rope, wherein the head section of the main floating body is semi-spherical, the middle section of the main floating body is cylindrical, four empennage plates on the tail contraction section of the main floating body are distributed in an X shape, and the whole main floating body is in streamline form. Four uniformly-distributed sets of hydraulic safe suspension devices are attached to the vector hydrophone in the processes of assembling, adjusting and transporting and kept certain positive pressures, and separated from the vector hydrophone under the pressure of seawater at a certain depth of water after the suspension devices are laid, so that the vector hydrophone is in a free suspension state; and in the process of recovery, the suspension devices are deadlocked again under the condition of less than a certain seawater pressure, thereby avoiding that the vector hydrophone is damaged due to collision. The trifurcate mooring rope is connected with a frame mooring seat of the main floating body, so that the main floating body is always in a horizontal mooring state under the water. The platform ensures the reliability of long-term underwater running of systems.
