Description
Technical field
The present invention relates to be applied to the counter weight construction of towed linear array, relate to joining of a kind of applicable towed linear array
Refitting is put.
Background technology
Towed linear array is a kind of main acoustic sounding equipment, is widely used in oil exploration and target acquisition etc.
Field.Linear array detection performance is affected by factors such as underwater sound propagation characteristics in marine environment and ocean, Qi Zhongshui
The impact of acoustic propagation characteristic is especially prominent.Same a set of towed linear array, because user is to acoustic propagation characteristic
Degree of understanding is different, can obtain diverse result of detection.Therefore, user needs according to hydrology letter when using
Sound velocity profile in breath, that reasonably selectes acoustic module section in linear array lays the degree of depth, gives full play to pull-type
The detectivity of linear array.
Towed linear array is made up of towing cable, connection damping section, acoustic module section and rear etc., and it connects damping
The density of section, acoustic module section and tail rope is suitable with density of sea water, substantially zeroed buoyancy, and the density of towing cable is generally
1.3 2 times of density of sea water.There are two kinds of methods at present for regulating the degree of depth of acoustic module section.One is to utilize institute
" aquatic bird " of meaning, this is the mechanical lifting gear of a kind of cable remote controlled with signals, is attached on towing cable oversheath.Logical
Cross the signal of transmission " aquatic bird " upper and lower floating, control the raising and lowering of " aquatic bird ", it is achieved acoustic module section
Reach the degree of depth needed.Another is the relation utilizing streamer length and towed speed, it is achieved acoustic module Duan Da
To the degree of depth needed.When towed speed one timing, towing tension and down force caused by towing just become with the quality of towing cable
Ratio, so that the submergence depth of acoustic module section is directly proportional to streamer length.When streamer length one timing, acoustics
The submergence depth of modular segment is inversely proportional to towed speed.
First method is owing to manufacturing complexity, and cost is high, and application scenario is little.Second method need not additionally set
Standby, only by controlling streamer length and towed speed, can be achieved with the degree of depth that acoustic module section reaches to need, application
Occasion is a lot.But, the streamer length laid at some special occasions is limited, and second method is inapplicable.Such as,
Maritime patrol ship is when monitoring the detection ship of the other side, and the cable laid is oversize, can affect the mobility of ship, hold to right-safeguarding
Method brings difficulty.During the work of double towed linear arrays, for increasing its space size information, it is also desirable to two lines array
To lay the degree of depth different.For this in the urgent need to a kind of device of invention, the shorter and two wires control system at the cable length laid
Lay when needing difference in height, meet acoustic module section and reach the degree of depth of needs, give full play to the spy of towed linear array
Survey ability.
Summary of the invention
