Abstract
This invention relates to one underwater cable sealing structure, which Comprises soft tube rapid terminals and is characterized by the following: the one pair of varies radium joints between soft tubes are connected to be matched by sealed screw; Realizing thin and thick tubes two end sealing through inside tamper sealed mouth and screw. This invention realizes the sealing tube and its cable plug and socket; the above radium rapid plug is formed by small and large screw caps with small sealed mouth and large joint.
Description
Technical field
The present invention relates to a kind of containment member that is used for submerged cable.
Background technology
The cable seal problem of underwater operation equipment is the emphasis and the difficult point of domestic and international correlative technology field always, because the Seal of Cables effect has directly determined service behaviour, useful life and the practicality thereof of underwater installation, thereby, the Seal of Cables member is the critical component of submerged cable, relevant department has successively developed diversified submerged cable containment member both at home and abroad, mainly be that mode with the vulcanization of rubber has designed various underwater sealing connectors, can be used on the following depth of water of 5000m.But, for the mini-plant of shallow water operations, use such containment member to have the defective of following three aspects:
1. cost is too expensive; With the deep-sea cable containment member that can be used for the 5000m depth of water is example, the supplier mainly provides two cover cable plug sockets at present, the price of every cover is generally in RMB 600---between 1000 yuan, like this, make a cable and just need 1200---2000 yuan, and also cable needs special process to be vulcanized could to use.If need to use many cables on a set of equipment, then its cost is a white elephant for the general user.
2. maintenanceability is poor; Owing to generally used sulfuration process in the manufacturing of present cable seal member and the processing technology, thereby in a single day this member break down or damage, and generally can't keep in repair at the scene, normally directly changes the whole piece cable.
3. maintenance cycle is long; The sulfuration of cable-to-cable connector and watertight cable thereof, consuming time generally speaking more than 24 hours, if cable core number diameter a lot of or containment member is very big, then the processing time can be longer, causes the long-term pause of marine maintenance activity, and cause a large amount of wastes.
Present existing snap joint is the connection usually used as pneumatic element mesohigh breather pipe and the parts of sealing, is also used widely.
Summary of the invention
The purpose of this invention is to provide a kind of low cost, good reliability, and keep in repair the containment member of easy submerged cable, to remedy the deficiency on the prior art.
The present invention is on the basis of two ends for existing snap joint, has added a pair of custom-designed reducing snap joint again, as the novel combination snap joint of underwater sealing connector, becomes the present invention together with the seal tube mutual group that is connected therebetween.
Thereby, the present invention includes the snap joint of two ends for the band small hose, it is characterized in that therebetween also being connected, and be fastenedly connected with suitable sealing nut and form with a pair of reducing snap joint that socket-connects by thick flexible pipe sealing.Sealed mouth and sealing nut by band taper surface in it are realized the sealing at thin, thick flexible pipe two ends.
Realize that like this cable walks in the thick flexible pipe of sealing, with and cable on cable plug and socket plug within it.
The essence of above-mentioned reducing snap joint is the snap joint that is rotary with little sealed mouth with the big sealed mouth of little nut and big nut by two ends respectively.
Characteristics of the present invention be simple in structure, easy and simple to handle, for ease of maintenaince, with low cost, and good reliability.Corrosion resistant metal spare the best is used in snap joint of the present invention and reducing snap joint, and the life-span is long, gets final product so the cable that utilizes containment member of the present invention when the maintenance cable, only need be changed flexible pipe usually, and is simply, easily and fast, with low cost.Simultaneously, the flexible pipe that the seal head of snap joint and reducing snap joint is connected bear for external pressure, so the increase of hydraulic pressure not have to influence to the sealing property of member substantially, effectively guaranteed the reliability of containment member.
Description of drawings
Fig. 1 basic structure schematic diagram of the present invention.
Fig. 2 reducing snap joint of the present invention decomposition texture generalized section.
Fig. 3 basic structure decomposing schematic representation of the present invention.
Wherein, 1 snap joint, 2 small hoses, 3 reducing snap joints; 4 thick flexible pipes, 5 reducing snap joints, 6 small hoses, 7 snap joints, 8 little nuts, 9 little sealed mouths, 10 big sealed mouths, 11 big nuts.
Embodiment
The present invention includes the snap joint 1,7 of two ends, it is characterized in that therebetween also being connected, and be fastenedly connected with suitable sealing big nut 11 and form with a pair of reducing snap joint 3,5 that socket-connects by thick flexible pipe 4 sealings for band small hose 2,6.
Above-mentioned reducing snap joint 3 is identical with the structure of reducing snap joint 5.The structure of above-mentioned reducing snap joint 3,5 and snap joint 1,7 is close.
The essence of above-mentioned reducing snap joint 3,5 is the snap joint that is rotary with little sealed mouth 9 with the big sealed mouth 10 of little nut 8 and big nut 11 by two ends respectively.
Two snap joints 1,7 are connected with the sealed cabin body of existing device respectively, are connected with sealing ring with screw thread usually, also itself and warehouse directly can be welded knot together; The thin end of snap joint 1 and reducing snap joint 3 is connected with small hose 2, realizes the sealing at small hose two ends by little sealed mouth 9 and fastening little nut 8; The butt end of two reducing snap joints 3,5 is connected with thick flexible pipe 4, and type of attachment is identical with snap joint 1.Above-mentioned thin, thick flexible pipe generally adopts the PU pipe.
During use, the thin end of two snap joints at first from beginning to end and two reducing snap joints connects with small hose 2, to weld two cables of plug, socket then and introduce small hose 2,6 by the threading hole of reducing snap joint butt end respectively, and then pass the threading hole introducing equipment warehouse of snap joint, and be connected firmly with corresponding power supply terminal; Next step is connected thick flexible pipe 4 with the butt end of one of them reducing snap joint, after plug, the socket of two cables can being docked, the butt end of this thick flexible pipe 4 with another reducing snap joint 5 is tightly connected again.By aforesaid operations, just finished the connection procedure of the containment member of a submerged cable.
The caliber size of snap joint and seal tube depends on the diameter of cable and cable plug socket, and the length of seal tube can be according to the length intercepting of cable needs.
The present invention has following two kinds of occupation modes:
1. a cover member uses for a cable: when needing in the equipment use to avoid the phase mutual interference of different power supplies and communication cable, different circuits can be sealed separately with different members;
2. a cover member uses for many cables: when not needing in the equipment use to consider the phase mutual interference of different power supplies and communication cable, and can be with many shared big mouth of sheath of cable footpath members.
