Description

Strong electric-signal cable deck-piercing apparatus
Technical field
The present invention relates to the cable penetrating device, particularly relate to a kind of strong electric-signal cable deck-piercing apparatus of dry welded high pressure test compartment.
Background technology
At present, mainly can be divided into three kinds of shroud tub type, high pressure type and gerotor types to the repair by welding of submarine pipeline dry type, wherein high pressure dry welding high undersea hydrostatic pressures dry type welding maintenance technique was taken the lead in 1954 proposing by the U.S., began to be used for to produce the successful repair by welding charge book of the existing following deepwater field of 300m in 1966 in marine site, the North Sea.Except life support under water, outside the corollary systems such as the water surface and underwater communication contact, the key problem of underwater dry-type high pressure welding maintenance technique at first is underwater dry-type high pressure welding procedure, because pressure of ambient gas, the environmental gas composition, the variation of factors such as repair by welding subject material characteristic, the capital makes the welding arc characteristic, metallurgy characteristic and welding procedure characteristic are subjected to influence in various degree, thereby before welding repairing work under water, all need welding condition is studied at every turn, just need set up corresponding high pressure dry STUDY ON THE WELDING experimental rig, the main body of experimental rig is exactly the high pressure welding experimental cabin for this reason.
The high pressure welding experimental cabin must can satisfy following requirement: the gaseous environment of pressure corresponding to the concrete depth of water can be simulated and keep in (1) in the cabin, promptly can realize reliable gases at high pressure sealing; (2) can in the cabin, carry out the high pressure weld job; (3) the various welding actions in the high pressure welding process can be controlled by the personnel that are in the outer atmospheric pressure environment of experimental cabin; (4) some relevant with weld seam or molten bath in welding process image informations or scene information can be transferred in the outer atmospheric pressure environment of experimental cabin and use for the researcher; (5) can monitor situations such as the temperature of gaseous environment in the welding process pilot scale hatch checking, humidity, change of component; Or the like.Just must use a large amount of cable penetrating devices, to solve various strong and weak electricity signals at transmission between the different pressures environment or transmission problem inside and outside the high pressure welding experimental cabin for this reason.
As shown in Figure 1, it is the often structural representation of a kind of strong electric-signal cable deck-piercing spare of employing of pressure vessel industry, perforate has been welded an abnormity and has been taken over 92 on container cavity 91, the endoporus of adapter 92 has three kinds of different diameters, the diameter of minimum diameter hole section and used cable 93 matches and is bigger than it, does not contact with the adapter body to guarantee cable 93; Be processed with internal thread in the maximum endoporus section of taking over 92 outermost end, hold cable 93 tightly to guarantee sealing with extruding asbestos or block rubber thereby promote briquetting 95 by rotation plug screw 94.The maximum not enough of this scheme combines manufacturing and designing with manufacturing and designing of pressure vessel of crossing cabin spare together exactly, after in case the physical dimension of abnormity adapter 92 is decided, the structure of whole crossing cabin spare and sealing means thereof are also determined thereupon, can't be made improvements again; While in case the internal thread of abnormity adapter 92 etc. is located to break down, and is bigger to its difficulty of carrying out maintenance and renovation.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, good airproof performance and be particularly suitable for the cable penetrating device of the forceful electric power signal of dry welded high pressure test compartment.
For achieving the above object, the present invention takes technical scheme: a kind of strong electric-signal cable deck-piercing apparatus, the outside that tapped blind hole that it is offered by the bulkhead outside and attachment screw are arranged on bulkhead, it includes: a body, its central authorities are provided with a lining storage tank, and corresponding described tapped blind hole is provided with through hole around it; One interstage bushing, its cross section are " fourth " font, and axial hollow, and the inner wall at end of this interstage bushing is provided with internal thread; One cable snap joint, its front end outer wall is provided with external screw thread, and is connected with the internal thread of described interstage bushing end by this external screw thread; One double end screw rod, the center of its terminal stube cable snap joint, its front end passes described bulkhead and extends in the bulkhead.
In practical operation, the front inner wall of described cable snap joint is provided with internal thread, and is connected with the external screw thread of described double threaded screw end by this internal thread.In addition, the junction of described body and cabin body, and the junction of described body and described interstage bushing is provided with seal washer; The junction of described interstage bushing and cable snap joint also is provided with seal washer.
In the above-mentioned strong electric-signal cable deck-piercing apparatus, described interstage bushing is made by insulating material.Be provided with rubber washer between described double threaded screw and the perforation of cabin body.In addition, the end of described cable snap joint is provided with cable interface.
The present invention is owing to take above design, it has the following advantages: 1, the present invention can satisfy the requirement of all kinds of pressure vessel cable penetrating spare structural designs under the different operating modes, have bigger versatility, and it is specially adapted to the cable penetrating device of the forceful electric power signal of dry welded high pressure test compartment.Even 2, the present invention is simple in structure, the good airproof performance part breaks down, it is also very easy that it is carried out maintenance and renovation.
