Liftable acoustic sounding instrument compartment system

Abstract

The invention discloses a liftable acoustic sounding instrument compartment system, comprising an instrument compartment, an internal concave compartment space arranged at the bottom of a hull, and aPLC arranged in the hull, wherein at least 3 guide posts are arranged on top of the instrument compartment, guide sleeves movably connected with the guide posts are arranged on top of the internal concave compartment space, a flexible device is arranged on top of the instrument compartment and the flexible device is movably connected with the top of the internal concave compartment space and the PLC is connected with all the parts through a hydraulic control system; when an array acoustic sounding instrument is not used in a ship, the instrument compartment can be lifted back to the bottom ofthe instrument compartment and is basically flushed with the bottom of surrounding ships, fuel consumption of the ship in an average voyage is permanently and greatly reduced, requirements for an underwater environment and harbor water depth in the water area of the voyage are lowered and restriction on the use of a bow side thruster is not caused. While heavily promoting detection efficiency of ships and improving working conditions of detection, the usage cost of ships is remarkably reduced.

Description

technical field [0001] The invention relates to the field of professional detection ship acoustic detection instruments, in particular to a flying wing-shaped detection acoustic instrument cabin system that is movably installed on the bottom of a detection ship and can be raised and lowered. Background technique [0002] In the field of professional detection and scientific investigation ships, most ships are equipped with professional sonar underwater acoustic detection instruments for underwater detection and inspection operations. According to the detection purpose and performance requirements, different types of acoustic detection instruments will be placed in different parts of the ship in different ways, and underwater detection will be carried out during the ship's navigation to achieve the purpose of detection operations. But at the same time, all acoustic detection instruments cannot be affected by obvious turbulence, air bubbles and noise, otherwise their detection...

AI Technical Summary

Problems solved by technology

The disadvantage of this method is that: the acoustic cabin that protrudes permanently from the bottom of the ship has been proved by various methods such as hydrodynamic calculation, ship model test and actual ship verification, and its influence on navigation resistance reaches about 20%, which means it will increase the ship’s energy by 20% consume

At present, a mainstream 5,000-ton scientific research ship consumes about 7 to 10 tons of fuel per day during voyage, and the annual voyage time is about 280 to 300 days, while the operating time of deep-water multi-beam array sonar is usually used by detection ships. Accounting for only 5% to 10% of the total voyage time, this additional consumption is permanent even without detection operations, which will cause staggering additional economic costs and environmental pollution during the decades-long service life of the ship

In addition, the instrument cabin that permanently protrudes from the bottom of the ship also has high requirements for the underwater environment of the ship's navigation area, especially the coastal area, and the water depth of the port of call, otherwise it is easy to be entangled and damaged by fishing nets and underwater foreign objects, or there is a risk of bottoming out. Causes damage to expensive acoustic instruments or the hull itself, greatly restricting the ship's navigation and port range
