Abstract
The utility model relates to a kind of opening cap underwater device, comprises separate cover, aircraft cabin body, the de-head of separate cover, base, screw plug, spring, slide bar, safety air bag, control capsule and wire.Overcome the deficiency that existing cap-opening mechanism exists, the practical function that reach easy for installation, simple to operate, reliability is high.
Description
Technical field
The present invention relates to a kind of opening cap underwater device.
Background technology
The development and utilization of ocean has become an important topic of various countries' scientific research, the test of carrying out along with military, civilian environment under water and the continuous increase of experiment, and various submarine navigation devices continue to bring out and apply.But no matter the successful utilization of which kind of submarine navigation device, all needs by forming failure-free product after a large amount of experimental verifications; On the other hand, after aircraft is finished the work under water, for obtaining various information, also need aircraft to salvage and reclaim.Now adopt air bags to expand to increase buoyancy completes recovery, and in this removal process, a step of most critical is, before air bag expands, the enclosing cover of submarine navigation device can smooth opening, is unlikely to hinder the expansion of air bag, has occurred polytype cap-opening mechanism for this reason.
Such as, explosive bolt formula cap-opening mechanism, although simple in structure, reliability is high, but there is in actual applications certain danger, as in experiment assembling and debug process, accidentally occur unexpected, all can cause great bodily injury to instrument and equipment and operating personal, consequence is hardly imaginable; Another kind of as steel ball separation-type cap-opening mechanism, although overcome the danger that gunpowder product bring, structure is too complicated, when assembling and setting, takes time and effort, and because the parts of this cover-opening structure use are more, is difficult to guarantee the reliability of arrangement works simultaneously.For overcoming above-described shortcoming, in use in the urgent need to a kind of novel, easy for installation, simple to operate, cap-opening mechanism that reliability is high.
Summary of the invention
The technical matters solving
For fear of the deficiencies in the prior art part, the present invention proposes a kind of new mechanism for opening cap underwater.
Technical scheme
A kind of opening cap underwater device, is characterized in that comprising separate cover 1, aircraft cabin body 2, de-3 of separate cover, base 4, screw plug 5, spring 6, slide bar 7, safety air bag 8, control capsule 9 and wire 10; Wherein separate cover 1 is placed on aircraft cabin body 2, and safety air bag 8 is connected by bolt and aircraft cabin body 2, and the bottom of safety air bag 8 is connected with control capsule 9 by wire 10; Safety air bag 8 both sides are provided with arming mechanism, described arming mechanism comprises de-3 in base 4, screw plug 5, spring 6, slide bar 7 and separate cover 1, wherein base 4 is bolted with aircraft cabin body 2, screw plug 5 is threaded connection with base 4, slide bar 7 is arranged in the hole adapting with its size on base 4, mounting spring 6 between screw plug 5 and slide bar 7, de-3 between two slide bars 7.
The through hole that contains one section of screw thread on base 4.
Beneficial effect
A kind of opening cap underwater device that the present invention proposes, overcomes the deficiency that existing cap-opening mechanism exists, the practical function that reach easy for installation, simple to operate, reliability is high.

Detailed description of the invention
Now in conjunction with the embodiments, the invention will be further described for accompanying drawing:
A kind of opening cap underwater device, comprises separate cover 1, aircraft cabin body 2, de-3 of separate cover, base 4, screw plug 5, spring 6, slide bar 7, safety air bag 8, control capsule 9 and wire 10; Wherein separate cover 1 is placed on aircraft cabin body 2, and safety air bag 8 is connected by bolt and aircraft cabin body 2, and the bottom of safety air bag 8 is connected with control capsule 9 by wire 10; Safety air bag 8 both sides are provided with arming mechanism, described arming mechanism comprises de-3 in base 4, screw plug 5, spring 6, slide bar 7 and separate cover 1, wherein base 4 is bolted with aircraft cabin body 2, on base 4, contain through hole and wherein one section be processed with screw thread, screw plug 5 is threaded connection with base 4, can realize the control to spring initial compression amount by the screw-in depth of controlling screw plug 5, reach the required coupling mechanism force requirement of above-mentioned cap-opening mechanism with this.Slide bar 7 is arranged in the hole adapting with its size on base 4, mounting spring 6 between screw plug 5 and slide bar 7, and de-3 between two slide bars 7.
Installation process of the present invention is: first screw plug 5, slide bar 7, spring 6 are arranged in base 4, adjust the screw-in depth of screw plug 5 according to required pressure, then base 4 and aircraft cabin body 2 are passed through to bolted connection, as shown in Figure 3,4, finally separate cover 1 is directly pressed down, complete installation as shown in Figure 1, 2.
The specifically process of uncapping of this cap-opening mechanism is: in the time that aircraft need to reclaim, control capsule 9 receives the quick-fried safety air bag 8 that makes of system directs, safety air bag 8 is detonated rear rapid expanding, and exert pressure to separate cover 1, in the time that expansion pressure exceedes slide bar 7 and acts on the coupling mechanism force of de-head part 3 of separate cover, separate cover 1 jumps the traces and moves up, slide bar 7 slides in hole, spring 6 compresses, air bag continues to expand, the pressure that is applied to separate cover 1 increases, separate cover 1 continues to move up, when its maximum width of the de-head part 3 of separate cover moves past after slide bar 7, by slide bar 7, spring 6, the locking mode that the de-head part 3 of separate cover forms is disengaged, under the effect of air bag swelling force, separate cover 1 is opened, come off, complete the process of uncapping, now structural representation as shown in Figure 5, safety air bag 8 is by the requirement of setting, continue to expand so that required positive buoyancy to be provided, aircraft floating can complete recovery.
