Description
Technical field
The utility model relates to a kind of underground releaser technology, the pneumatic cutting release gear of particularly a kind of timing.Be used for from buoyancy aid of carrier separation under water and cut-out communication cable.
Background technology
Existing buoyancy aid underground releaser from discharging principle under water, all is to impel piston or pin to move with respect to matrix by propulsion source, makes mechanism action, discharges and the cutting task thereby finish.These release gears to be adopted to finish by inertia, the time-delay of sugar (salt) piece and hydraulic pressure and discharges and cutting, and impulsive force is big when discharging, time-delay is short, error is big, and can only discharge by depthkeeping, thereby the inconvenience use.Also having a kind of release gear is to adopt blast to finish release and cutting task.This method poor stability also can injure nearby device, and can not repeated usage, can't realize the function that discharges simultaneously and cut.In addition, in recent years, occurred a kind of underground releaser that adopts spring installation on the market again, this device volume is bigger, and structure is also complicated, and assembly technical requirement is higher, uses inconvenience, and reliability is low.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes prior art, provide a kind of catchment discharge down, two kinds of functions of cutting are in one, and simple in structure, safety of operation, underground releaser accurately regularly.
For achieving the above object, the utility model proposes the pneumatic cutting release gear of a kind of timing.This device is made up of hydraulic pressure mechanism, separation device and control circuit board.Hydraulic pressure mechanism is made of hydrostatic membrane, hydraulic pressure bar, spring and micro-switch.Hydraulic pressure bar one end links to each other with hydrostatic membrane, hydraulic pressure spring, and the micro-switch that the other end links to each other with control circuit board approaches, so that can the smooth opening micro-switch.Separation device is made of hold concurrently cutter, catch and right matrix etc. of coyote hole, igniter, pin.Igniter is arranged in the coyote hole, and is electrically connected with control circuit board.Pin cutter one end of holding concurrently links to each other with coyote hole, and the other end touches with right matrix mutually by catch, so that can enter right matrix smoothly when making pin hold concurrently skive falchion movement, finishes buoyancy aid and discharges and the cable cutting action.
After the utility model entry, hydrostatic membrane and hydraulic pressure bar move downward under the hydraulic pressure effect, when reaching the depth of water of hydraulic pressure spring setting, the hydraulic pressure bar starts micro-switch, when control circuit board begins to walk, when reaching the schedule time, provide current signal immediately, make the igniter burning.Igniter burning can make and produce high pressure gas in the coyote hole, promotes the pin cutter of holding concurrently and moves right, thereby break through catch, enters right matrix, finishes and cuts off cable, separates the buoyancy aid action.High pressure gas lose heart by the bleeder port on the right matrix, plug screw safely with its retaining in right matrix, pin is held concurrently after cutter is pushed out, can be retained in the right matrix safety of bondsman or equipment, energy safety action dependable performance simultaneously, can not rebound, successfully finish release movement.
The utility model is owing to adopt regularly pneumatic cutting, thereby the function that has the cutting to finish simultaneously and discharge, and it is simple in structure, safety of operation, regularly accurately, be applicable to the carrier release of real-time transmission buoy system, and the thunder body of latent mine anchoring separates release of mooring body buffering and big degree of depth depthkeeping release with mine anchor.

The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is further described.Fig. 1 is the utility model structure principle chart.The utility model mainly is made up of fork guard 3, hydraulic pressure mechanism, separation device, control circuit board 20 etc., wherein hydraulic pressure mechanism is used for depthkeeping, constitute by hydrostatic membrane 24, hydraulic pressure bar 22, hydraulic pressure spring 23, micro-switch 21, link to each other with control circuit board 20 by micro-switch 21.Separation device is used to separate buoyancy aid, cutting cable, is made of hold concurrently cutter 15, the collar 16, catch 17, right matrix 18, plug screw 19 etc. of coyote hole 10, pressure ring 11, seal ring 12, igniter 13, pin.Igniter 13 wherein is arranged in the coyote hole 10, is electrically connected with control circuit board 20.Coyote hole 10 and pressure ring 11 are by being threaded, and seal ring 12 is contained on the electric igniter 13, compresses pressure ring 11, guarantee the sealing of electric igniter 13 left end in coyote hole 10, prevent infiltration and lose heart.The collar 16 is threaded with right matrix 18 usefulness, and catch 17 is fixing, simultaneously to pin 15 1 application forces of cutter of holding concurrently.Fork guard 3 is used for guaranteeing that product and equipment are in the safety of transporting, debugging, laying.The utility model principle of work is: after the utility model entry, hydrostatic membrane 24 and hydraulic pressure bar 22 are under the hydraulic pressure effect, move downward, set the depth of water when reaching hydraulic pressure spring 23, hydraulic pressure bar 22 starts micro-switch 21, when control circuit board 20 begins to walk, when reaching the schedule time, provide current signal, make igniter 13 burnings.The igniter burning produces a large amount of high pressure gas in coyote hole 10, cutter 15 moves right thereby the promotion pin is held concurrently, and breaks through catch 17, enters right matrix 18, the action that finish and cut off cable, separates buoyancy aid.High pressure gas lose heart by the bleeder port on the right matrix 18, and plug screw 19 is held concurrently pin cutter 15 retainings safely in right matrix 18, thereby guarantee the safety of operating personal and equipment, and safety action is accurate, reliable, can not rebound, and successfully finishes release movement.
The test that Fig. 2 provides generally speaking lays scheme drawing, and pneumatic cutting release gear 31 links to each other with carrying platform 30 among the figure, and hold concurrently cutter and cement anchor 33 (test with) of pin links to each other, the centre externally hanging battery 32 of ining succession.Pull out fork guard during work earlier, after the thunder body lays entry together with anchor, arrive and set the depth of water, micro-switch begins to start, when control circuit board began to walk, when reaching the schedule time, igniter ignited, promote the pin cutter of holding concurrently and move right, cut off cable and power supply simultaneously, finish release movement.Cut off power supply, can guarantee carrying platform 30 when salvaging personal security and the safety of naval vessels.Carrying platform 30 has certain buoyancy, under self buoyancy function beginning to rising, thereby be recovered.By a large amount of evidences, release gear can both regular event, regularly accurately.Use the depth of water to reach 1000m, discharge cutting power and reach 5000KN.
