Description
Technical field
The invention belongs to ship emergence technology fields, more particularly to a kind of ship emergency leak repairing component.
Background technique
With the fast development of China's shipping industry, vessel traffic flow increases sharply, and the probability that accident occurs for ship is more next
It is more, and once accident occurs since shipbreaking is easily caused into water, due to can not timely and effective leak stopping after ship leakage
Ship is easily caused to ruin the catastrophic failure that people dies.
Processing hull damage method point traditional at present or less is several:When broken hole is smaller, using cork or plugging plate
Carry out leak stopping;When being relatively large in diameter, the interim leak stopping of collision mat is selected, cement box leak stopping is used after draining;For crack, using flax silk
Or rag, rubber cover crack then stickfast;Currently, main leak stopper has collision mat, plugging plate, leak stopping case, leak stopping spiral shell
Bar, leak stopping column, emergency wooden plug etc., complex-shaped due to ship broken hole, usual pressure is larger at loophole, leakage rate is fast, because
And above-mentioned leaking-stopping measure is all it is difficult to ensure that the effect of leak stopping;These leaking-stopping measures are often the carry out leak stopping of single form, no
It can combine in several ways and carry out multiple leak stopping encapsulation process, while these leaking-stopping measure processing speeds are often relatively slow,
Outburst surroundings cannot be coped with.
Summary of the invention
The purpose of the present invention is to provide a kind of ship emergency leak repairing component, pass through leak stopping umbrella cloth, pressure bladder and close
The matching design of closing disk, solves that existing ship craft leakage mending kit form is relatively simple, not can be carried out asking for dual leak stopping sealing
Topic;By be engaged pawl, fixed ring and seal disc design, solve existing ship craft leakage mending component cannot have carry out outside to inside it is close
The problem of sealing and then realizing leak stopping;By the matching design of adjustment hole and adjusting bolt, solves existing ship craft leakage mending component
The problem of freely adjustment of position cannot be carried out according to loophole and leaking stoppage umbrella size cases.
In order to solve the above technical problems, the present invention is achieved by the following technical solutions:
The present invention is a kind of ship emergency leak repairing component, including interior bar;The interior bar week, side slidably connected support

9 one surface of pawl is fixedly connected to torsional spring 10;Four torsional springs 10 are fixedly connected with fixed ring 8 far from one end of occlusion pawl 9;Gu
Determine 8 one surface of ring and is fixedly connected with limit plate 11.
Wherein as shown in Fig. 2, 7 weeks sides of outer bar offer external screw thread 12;7 weeks sides of outer bar are connected by 12 screw thread of external screw thread
It is connected to seal disc 13;7 weeks sides of outer bar are threaded with fastening plate 16 by external screw thread 12;16 weeks sides of fastening plate are fixedly connected
There are four the handles 17 that exerts a force;1 one end of interior bar is fixedly connected with rotating handle 19;Interior bar 1 is fixed far from one end of rotating handle 19
It is connected with umbrella head 20.
Wherein as shown in Figure 3-4, occlusion 9 one surface of pawl is fixedly connected to torsional spring 10;Four torsional springs 10 are far from occlusion pawl 9
One end be fixedly connected with fixed ring 8;8 one surface of fixed ring is fixedly connected with limit plate 11.
Wherein as shown in figure 5,1 week side of outer bar 7 and interior bar is run through, there are four adjustment holes 21;Adjustment hole 21 is threaded with
Adjust bolt 22.
One of the present embodiment has particular application as:The leak repairing component is mainly used in the leak stopping processing of spitkit, occurs
Before leak, the leak repairing component of different size thickness should be prepared in ship, when leak stopping to be carried out, according to loophole size and damaged feelings
Condition should select the leak repairing component and support frame 3 and leak stopping umbrella cloth 5 of fair-sized and thickness, when loophole is larger, answer appropriate basis
It needs to increase support frame 3 and auxiliary skeleton 4, while will quickly adjust bolt 22 and be connected to suitable adjustment hole 21, when leak stopping,
Interior bar 1 is goed deep into outside loophole, makes outer bar 7 and support and then quickly adjusting rotating handle 19 and shortening the back-out length of interior bar 1
Ring 2 squeezes, and by squeezing, promotes support frame 3 and auxiliary skeleton 4 to open leak stopping umbrella cloth 5, water flow can be inside when opening
Impact floating ring 6, floating ring 6 thus to leak stopping umbrella cloth 5 apply inward force, force leak stopping umbrella cloth 5 be close to loophole outer surface, open completely
When opening, umbrella head 20 enters inside floating ring 6, and the two is fixedly connected under force, at this point, water flow disappears substantially, in leaking stoppage umbrella
While cloth 5 opens, occlusion pawl 9 opens under the elastic reaction of torsional spring 10, shortens the horizontal size of component, occlusion when leak stopping
Pawl 9 is stretched out in squeezed state, and after losing constraint after stretching, occlusion pawl 9 opens immediately, after occlusion pawl 9 opens, limit plate 11
It is limited, it is made to keep plumbness, pawl 9 is engaged at this time and is kept in contact with plumbness and hull, passed through again at this time
16 fit sealing disk 13 of fastening plate just substantially blocks loophole, at this point, inevitably have part water flow flow into seal disc 13, as into
The protection of one step, is inflated into pressure bladder 14, is full of pressure bladder 14 in seal disc 13 completely and then is blocked up from inside to outside
Firmly loophole, sealing ring 18 are used as further gain waterproof measure.
