Description
Technical field
The present invention relates to a kind of underwater target indication smoke generator, belong to target recovery technology field.
Background technology
In the development process of equipment, often subsea equipment need to be laid under water under water, after work a period of time, subsea equipment floats automatically, utilizes positive buoyancy to swim in the water surface.At this moment, utilize various indicating devices to show the subsea equipment position.After the search personnel find target, subsea equipment is reclaimed.
At present, indicating device generally has color identification, coloring agent dyeing etc.Because the target that subsea equipment floats on the surface is also little, when utilizing color identification, when if the subsea equipment water exit is unknown, when the factor such as add that sea situation is bad, floating debris is more in backlight search, sea affects, often to spends and just find thunder more than 2～3 hours; When utilizing coloring agent identification, also exist same problem, when distance reached 20 meters～30 meters far away, problem was even more serious, basically can not differentiate the sea and is colored the color that agent dyes, and can not find target.
Therefore, equipment floating aspect under water, need can intuitive, clear indication water outlet the device of target location.Also need this indicating device for the equipment that emerges on other, instrument, buoy etc.
Summary of the invention
The invention provides a kind of underwater target indication smoke generator, can send the eye-catching smog of color when upper floating apparatus floats to the water surface, can reach the raising searching efficiency, save the search expense, the requirement of shortening recovery time etc.
A kind of underwater target indication smoke generator comprises shell, smoke projectile, ignition wire, watertight mechanism, O shape circle, the hydrotrope, plug screw, tightens up material, pressing plate; External equipment is the subsea equipment workplatform, its housing is cylindrical metal case, a boss is arranged directly over shell, the manhole that boss inside has twice to connect in length and breadth, manhole communicates with enclosure longitudinally, horizontal manhole communicates with the boss cylindrical, and boss is along having a through hole and horizontal manhole to connect on axis direction; Its annexation is: smoke projectile is limited in enclosure by fastener material, and shell below is connected by the pressing plate watertight, has the ignition wire through hole on pressing plate, and ignition wire crossing point live wire hole is connected with smoke projectile; At the inner along continuous straight runs of the horizontal manhole of shell, watertight mechanism, the hydrotrope and bolt are installed successively, the position that the hydrotrope is installed is over against boss along the through hole on axis direction.The O shape that is set with in watertight mechanism encloses sealing function, prevents that seawater from entering enclosure from the boss of shell along the through hole on axis direction; The hydrotrope plays safety effect, together with plug screw, position-limiting action is played in watertight mechanism at ordinary times, the sealing property of assurance device, and the indication fuming device integral installation is the top of equipment workplatform under water.
Mode of operation: when the subsea equipment workplatform that target indication fuming device is housed was worked under water, due to the through hole on the shell boss of entering of seawater, the hydrotrope was melted away, and has removed the insurance of watertight mechanism; After the subsea equipment workplatform emerges, the depth transducer of subsea equipment workplatform self sends ignition signal, smoke projectile sends smog after lighting by ignition wire, enclosure pressure increases gradually, pressure is pushed watertight mechanism open, and smog is discharged the water surface by boss along the through hole on axis direction through manhole longitudinally, and the smog on the water surface presents color, by the identification of smog, can find the subsea equipment workplatform that emerges.
Beneficial effect:
1, the compressive resistance of smoking device is high, and operating depth is not less than 280 meters, can be with work of diving beneath the water such as test facility, instrument, platforms, and its compressive resistance almost can satisfy the depth of water in all rivers, lake, also can satisfy most of deep water offshore.Emerge with the subsea equipment workplatform after end-of-job, come the indicating target position by the smog that sends.
2, adopt water-soluble safety device, make its ability arming after entry.Install the built-in hydrotrope, the hydrotrope of packing into before entry tightly withstands watertight mechanism, prevents from laying vibrations in process, jolting etc. affects the water tightness of this device; After the device entry, the hydrotrope dissolves, and insurance is removed, for motion space is abdicated in the motion of watertight mechanism.
3, adopt self adaptation hydraulic pressure watertight technology, after device entry arming, utilize external water pressure that watertight mechanism is exerted pressure, reach the effect of watertight; After the equipment workplatform was finished the work and emerged under water, external water pressure disappeared, and watertight mechanism utilizes the static friction force that self elastic deformation produces to proceed watertight to device.
When 4, smoking device is worked, internal pressure constantly increases, after the pressure to watertight mechanism surpasses static friction force, watertight mechanism setting in motion, for smog emission is abdicated smoke-outlet flue, enter after smog is discharged aerial, the indicating target position, the time of being fuming is not less than 3 minutes, and visual range is not less than 3600m.
When 5, the mouth of being fuming on the subsea equipment workplatform is positioned at 0.5 meter of underwater, can guarantee that still smoking device is working properly.
