Description
Technical field
The utility model relates to a kind ofly indicates smoking device with target under water, belongs to target recovery technology field.
Background technology
In the development process of equipment, often subsea equipment need 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, during factor affecting such as add that sea situation is bad, floating debris is more in the backlight search, sea, 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, can not differentiate the sea basically and is colored the color that agent dyes, and can not find target.
Therefore, equipment come-up aspect under water, need can intuitive, clear indication water outlet target location device.Also need this indicating device for the equipment that emerges on other, instrument, buoy etc.
The utility model content
The utility model provides a kind of and indicates smoking device with target under water, can send the eye-catching smog of color when last floating apparatus floats to the water surface, can reach the raising searching efficiency, saves the search expense, the requirement of shortening recovery time etc.
A kind ofly indicate smoking device with target under water, comprise shell, smoke projectile, ignition wire, watertight mechanism, O shape circle, the hydrotrope, plug screw, tighten up material, pressing plate; External equipment is the subsea equipment workplatform, wherein shell is a cylindrical metal case, a boss is arranged directly over the 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 a through hole and horizontal manhole perforation are arranged on the axis direction; Its annexation is: smoke projectile is limited in enclosure by fastener material, and the shell below has the ignition wire through hole by the pressing plate leak-tight joint on the pressing plate, and ignition wire crossing point live wire hole is connected with smoke projectile; In the manhole inside that shell is horizontal watertight mechanism, the hydrotrope and bolt are installed successively from left to right, the position that the hydrotrope is installed over against boss along the through hole on the axis direction.The O shape that is set with in the watertight mechanism encloses sealing function, prevents that seawater from entering enclosure from the boss of shell along the through hole on the axis direction; The hydrotrope plays safety effect, with plug screw position-limiting action is played in watertight mechanism at ordinary times, the sealing property of assurance device, and the integral installation of indication smoking device is equipment work flat-bed top under water.
Mode of operation: when the subsea equipment workplatform work drowned of target indication smoking device is housed since seawater enter through hole on the shell boss, the hydrotrope is 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 the 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 height of smoking device, operating depth is not less than 280 meters, can be with work of diving beneath the water such as test facility, instrument, platforms, its compressive resistance almost can satisfy the depth of water in all rivers, lake, also can satisfy most of deep water offshore.Behind end-of-job, emerge, come the indicating target position by the smog that sends with the subsea equipment workplatform.
2, adopt water-soluble safety device, make its ability arming after entry.Install the built-in hydrotrope, entry is pre-installed goes into the hydrotrope and tightly withstands watertight mechanism, prevent in the process of laying vibrations, jolting etc. influences the water tightness of this device; After the device entry, the hydrotrope dissolves, and insurance is removed, for the watertight motion of mechanism is abdicated motion space.
3, adopt self adaptation hydraulic pressure watertight technology, after the device entry arming, utilize external water pressure that watertight mechanism is exerted pressure, reach the effect of watertight; After the equipment work platform was finished the work and emerged under water, external water pressure disappeared, and the static friction force that watertight mechanism utilizes self elastic deformation to produce is proceeded 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, after discharging, smog enters in the air 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.
