Movable lift quad-hull type underwater measuring platform

Abstract

The invention discloses a movable lift quad-hull type underwater measuring platform, which belongs to the technical field of marine monitoring and underwater acoustic measurement. The platform comprises pontoon modules, an upper frame, a hydrophone mounting bracket, underwater winches, a varying-voltage cabinet, a control cabinet, an attitude course pressure sensor and anchoring modules. Four pontoon modules are respectively symmetrically arranged at four corners of the bottom of the upper frame. Four underwater winches are respectively connected with the underwater winch mounting base of the pontoon modules and are respectively connected with four anchoring modules. The varying-voltage cabinet and the control cabinet are connected with the buoyant adjustment pontoon of a pontoon module respectively. The hydrophone mounting bracket is arranged at the top surface of the upper frame. The attitude course pressure sensor is arranged at the bottom of the beam of the H-shaped frame of the upper frame. According to the invention, deployment and recycling of predetermined depth of water in a predetermined sea area can be completed; the platform can maintain a stable attitude under the water; and ship noise measurement is smoothly completed by carrying an acoustic measuring device.

Description

technical field [0001] The invention belongs to the technical field of marine monitoring and underwater acoustic measurement, and in particular relates to a mobile liftable four-hull underwater measurement platform. Background technique [0002] Radiation noise is one of the most important operational performance indicators of submarines. In recent years, all naval powers in the world are vigorously developing quiet submarines, and the noise test of real boats is the basis and premise for realizing noise reduction of submarines. The true level of submarine noise can be evaluated through the noise measurement of the actual ship; and then by analyzing the noise source, the main noise equipment can be located, and then corresponding noise reduction measures can be taken, and the effectiveness of the noise reduction measures taken can be further verified. [0003] While vigorously developing low-noise submarines, all naval powers are paying more and more attention to the develo...

AI Technical Summary

Problems solved by technology

The establishment of a submarine underwater acoustic test site plays a key role in reducing the noise of submarines. There are many factors to consider in the site selection of the underwater acoustic test site, such as low background noise, wide water area and water depth that can meet the underwater maneuvering requirements of submarines, suitable weather conditions, and distance from the submarine home port. As close as possible, there are very few sites that can meet the above conditions, and the cycle of planning demonstration and construction is long
