Description
Technical field
The invention belongs to extra large cable locking water-tight device field, be specifically related to a kind of undersea armored cable lock sealing device.
Background technique
Present domestic sea floor optoelectronic cable is fixed or is peeled off and concentrated this dual mode of attached cable armouring wire with the whole clamp of many employings of being connected of underwater installation; the former is that the indirect securement armouring wire plays the locking purpose by holding the resistance to wearing serving of cable tightly with clamp; this structure coupling mechanism force is little and the cable external protection had damage, and seawater also corrodes armouring wire easily.The latter also needs the steel wire with belted type cable to separate to fix, also can cause armouring wire to expose corrosion, influence working life.
Summary of the invention
The purpose of this invention is to provide a kind of undersea armored cable lock sealing device, this device can be locked the requirement of satisfying the maximum carrying of belted type cable pulling force to cable effectively, can not be exposed to armouring wire in the seawater again, thus the working life and the reliability of raising belted type cable.
Lock sealing device of the present invention includes: bearing, be fixed on closed chamber and flange internal cones on the bearing, the pressure cap of spiral seal bearing afterbody and the locking pressure plate that is positioned at closed chamber is characterized in that, also include locking block and taper colloid in the flange internal cones; Wherein locking block is positioned at flange internal cones head, and locking block is provided with the wire casing of placing armouring wire; The taper colloid is positioned at flange internal cones afterbody.
Above-mentioned wire casing is radioactivity on locking block arranges, and the wire casing cross sectional area is less than the armouring wire cross sectional area, and the number of wire casing equals the number of armouring wire on the locking block.
Above-mentioned locking block and locking pressure plate bolton.
Above-mentioned taper colloid is compressed into flange internal cones afterbody by the pressure cap spiral.
Above-mentioned device also comprises the sealing rubber body that is arranged between closed chamber and the locking pressure plate.
Above-mentioned bearing is a T shape bearing.
Pressure cap screw thread of the present invention compresses the taper colloid that is arranged at flange internal cones afterbody, and plays the effect of sealing flange internal cones cavity.During use the armouring wire of belted type cable is put into respectively in the wire casing of locking block, plays the fixed-site effect, again locking block is put in the flange internal cones together with armouring wire, make locking block and main body strong bonded with locking pressure plate.The armouring wire piece that promptly is locked is pressed on the flange internal cones like this, and the pressing plate that is locked again is pressed in the wire casing of locking block, has satisfied the locking requirement of belted type cable.And closed chamber is the front end at locking device, protects the sealing after the cable armor steel wire is peeled off and prevents seawater corrosion.
The present invention is simple in structure, compact, it is identical to accomplish each root armouring wire coupling mechanism force, and easy for installation.Be connected and fixed mode with existing belted type cable and compare, the present invention is locking cable effectively, satisfies the maximum carrying of belted type cable pulling force, armouring wire is not exposed in the seawater again, avoids corrosion, can obviously improve the working life and the reliability of belted type cable.Device of the present invention can be applicable to land bank station and underwater facility such as pedestal under water.
