Abstract
The utility model discloses a water-seal stuffing box of an underwater cable inlet wire, which comprises a stuffing cylinder, a stuffing gland, an upper internal gasket and a lower internal gasket. The water-seal stuffing box is characterized in that: the stuffing cylinder is connected with a cable connection cabinet through a flange or is directly welded with the cable connection cabinet; a water-seal structure is arranged in the stuffing cylinder and between the upper internal gasket and the lower internal gasket, and is composed of compression sealing rubber, expansion sealing rubber and a compression and expansion piece which respectively adopt the structure of an O-shaped ring; and the compression and expansion piece is arranged between the compression sealing rubber and the expansion sealing rubber. The water-seal stuffing box of the underwater cable inlet wire has the following advantages: the water-seal stuffing box can effectively improve the water tightness of an underwater cable, is easy to install, is convenient to use, saves the maintenance cost of equipment, reduces construction labor force and can improve the construction quality.
Description
Technical field:
The utility model relates to stuffing box packing letter technical field, relates in particular to a kind of water-stop stuffing box of submerged cable inlet wire.
Background technique:
The underwater installation of dredger and other ocean engineering vehicles is more and more at present, the technology and the technical requirements of the water-stop joint of submerged cable access arrangement and crossing cabin wall water-stop stuffing box are more and more higher, and especially the cable water-stop inlet wire product and the technological requirement of deep water are higher.
Submerged cable water-stop inlet wire at present commonly used has following typical process and product:
1) pouring epoxy resin in stuffing box and the cable coupling box forms water-stop with the water-stop effect behind the epoxy cure to the electrical wiring position;
2) compress metallic shim by the locking stuffing box,, form sealing cable and stuffing box inwall by the distortion of metallic shim compacting caulking gum.If the degree of depth is excessive under water, can adds which floor metallic shim and water-stop rubber and carry out the water-stop protection.
First kind of product and technology are unfavorable for the maintenance and the maintenance of equipment, in case after the water-stop construction, cable joining cancels, and need change cable when safeguarding, and the maintenance cost costliness, maintenance work intensity is very big.
Second kind of product and technology are convenient to opening and inspecting of cable, have risk but use for the equipment of long-term deepwater work, and especially big Seal of Cables is used, and effect is relatively poor under the effect of big hydraulic pressure.
Summary of the invention:
Technical problem to be solved in the utility model provides a kind of water-stop stuffing box of submerged cable inlet wire, effectively improves the water tightness of submerged cable, installs succinctly, and is easy to use, and the maintenance cost of saving equipment is saved the construction labour force, improves construction quality.
The utility model solves the problems of the technologies described above the technological scheme that is adopted:
A kind of water-stop stuffing box of submerged cable inlet wire, comprise filling tube, Gland, go up inner pad and following inner pad, it is characterized in that: be connected by flange between described filling tube and the cable connection cabinet, or directly weld with the cable connection cabinet, in filling tube and in last inner pad be provided with watertight construction between the inner pad down.
Described watertight construction is made of compression seal rubber, Expansion sealing rubber and compression-expansion part and is O type coil structures, and the compression-expansion part places between compression seal rubber and the Expansion sealing rubber.
The outside disc of described compression seal rubber is provided with tapering, the inboard disc of compression-expansion part is equipped with identical tapering with outside disc, the inboard disc of Expansion sealing rubber is provided with tapering, and compression seal rubber, compression-expansion part, Expansion sealing rubber encapsulation successively form.
Described watertight construction is provided with 3 covers at least.
Described inner pad and following inner pad are stainless steel or copper pad.
The inwall of described filling tube is provided with sealing wire casing at interval.
Compared with prior art, advantage of the present utility model is:
1) be the flange connection between stuffing box and the cable connection cabinet, sealing means is an O type ring mechanical sealing, effectively improves the water tightness of submerged cable;
2) particularly stuffing box and cable connection cabinet directly weld, or stuffing box and flange be connected to and freeze, and have guaranteed whole water sealing property;
3) inner pad of stuffing box and compression-expansion part are stainless steel or copper, prevent from cable to be caused harmful effect because get rusty, particularly compression seal rubber and Expansion sealing rubber-moulding angle and compression-expansion part angle form good and sealing deformation fully, according to hydraulic pressure and seal request, the compression seal rubber and the expanded rubber sealing configuration that surpass 3 roads are set, thereby have guaranteed the water-stop effect.
In a word, the utility model cable gland structure can repeatedly be used, a large amount of submerged cable waste problems that cause because of plant maintenance of saving, secondly, improve the water-stop degree of submerged cable stuffing box greatly, guaranteed the normal operation of system, and install succinct, easy to use, saved the construction labour force greatly, the construction quality of raising.
Description of drawings
Fig. 1 is the water-stop stuffing box embodiment's of the utility model submerged cable inlet wire a structural representation;
The water-stop stuffing box embodiment's of the utility model submerged cable inlet wire watertight construction decomposition texture schematic representation in Fig. 2.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Shown in Fig. 1-2, the water-stop stuffing box of the utility model submerged cable inlet wire, comprise filling tube 1, Gland 2, go up inner pad 3 and following inner pad 4, filling tube 1 and one is welded on cable connection flange 5 cashier's office in a shop and is connected, or be connected with cable connection welded flange watertight screw cashier's office in a shop by the flange that is welded on the filling tube, or filling tube 1 directly is welded on cable connection cashier's office in a shop, on the inwall of filling tube 1, be provided with sealing wire casing 11 at interval, in filling tube 1 and between last inner pad 2 and following inner pad 3, be provided with watertight construction, this watertight construction is by compression seal rubber 6, Expansion sealing rubber 7 and compression-expansion part 8 constitute and are O type coil structures, and compression-expansion part 8 places between compression seal rubber 6 and the Expansion sealing rubber 7.Aforesaid watertight construction is provided with 3 covers at least, also is provided with inner pad 9 between every suit.Go up inner pad 3 and be stainless steel or copper pad with following inner pad 4.On flange 5, be provided with the connection screw, fixedly connected with the cable connection cabinet by screw.
Wherein the outside disc of compression seal rubber 6 is provided with tapering, the inboard disc of compression-expansion part 6 is equipped with identical tapering with outside disc, the inboard disc of Expansion sealing rubber 7 is provided with tapering, and the tapering difference on each components and parts, compression seal rubber 6, compression-expansion part 8, Expansion sealing rubber 7 encapsulation successively form, compression seal rubber 6 and Expansion sealing rubber 7 moulding angles and compression-expansion part angle 8 can form good and sealing deformation fully like this, thereby have improved the water-stop degree of submerged cable stuffing box greatly.
The utility model has solved the demand that the conventional maintenance of underwater installation is opened and inspect cable, and guarantees the effective water tightness of submerged cable, and reduces construction intensity and technical requirements.
