Horizontal mooring marine environmental noise vector field monitoring subsurface buoy platform

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.

Description

technical field [0001] The invention relates to a horizontally moored marine environment noise vector field monitoring submarine mark platform, which belongs to the field of marine environment monitoring equipment. Background technique [0002] Marine environmental noise monitoring is of great significance both in the military (such as acoustic fuze of underwater weapons, coastal warning, aviation sonobuoys, etc.), and in civilian (such as radiation noise monitoring, towed array, etc.). The vector hydrophone is composed of a sound pressure hydrophone and a sensor that can directly or indirectly measure the vibration velocity. It can simultaneously measure the scalar and vector of the underwater sound field (sound pressure gradient, particle velocity, acceleration, displacement and Sound intensity, etc.) information, which can obtain the sound wave information in the water without distortion, is an important equipment for monitoring the marine environment, especially the mari...

Problems solved by technology

However, the traditional vector hydrophone suspension method is mostly open, and the constantly changing flow direction makes the vector hydrophone with flexible suspension vibrate to a certain extent, which is not conducive to the normal operation of the vector hydrophone
