Description
Technical field
The invention belongs to also want auxiliary accessories technical field, and in particular to a kind of underwater dynamic cable clump weight.
Background technology
Dynamic extra large cable itself can cause larger displacement, bending, torsion, therefore need due to being influenced by wave ocean current
To be run in water according to certain line style, thus usually require assisted with clump weight, prevent submerged cable float or
Deviate designated position；Existing counterweight stock material uses lead material, and expensive, manufacturing process is easy to bring lead poisoning, easily
It pollutes the environment.
It is laid in construction and especially under shallow water area environment, due to the influence of ocean current wave, is vulnerable to external force and extra large cable
Slippage is generated, finally extra large cable is made to damage, influences service life；Under deepwater regions, since hydraulic pressure causes extra large cable radially to be received
Contracting, clump weight easily slide along extra large cable axial position.
Invention content
Goal of the invention：The purpose of the present invention is to solve deficiencies in the prior art, provide a kind of underwater dynamic cable use
Clump weight while generating radial tightening convergent force to extra large cable, plays the role of armouring protection.
Technical solution：A kind of underwater dynamic cable clump weight of the present invention, including two pieces closed up to half structure, mutually
Counterweight block body, the clump weight body interior axial direction, which is equipped with, accommodates the through-hole that passes through of dynamic cable, the clump weight sheet
Internal side is flank with dynamic cable contact surface, is equipped on the outside of the dynamic cable and is adapted the preload net engaged with the flank
Set.
Further, the counterweight block body is made of 316L stainless steels or other anti-corrosion materials.
Further, the outer application of the counterweight block body has antifouling paint.
Further, lifting lug is further fixed on the counterweight block body, the lifting lug is connected by connecting line with net cover is pre-tightened
It connects.
Further, the connecting line uses steel wire.
Further, it is additionally provided on the counterweight block body and accommodates the through-hole that bolt passes through.
Advantageous effect：Beneficial effects of the present invention are as follows：
（1）While the preload net cover of arrangement can generate radial tightening convergent force to extra large cable, play the role of armouring protection；
（2）The layout of distributed clump weight can prevent submerged cable from floating or deviateing designated position, make extra large cable according to setting in advance
Alignment type is run；
（3）Clump weight uses 316L stainless steels, outer layer to coat antifouling paint, can effectively provide counterweight and resist the corruption of seawater
Erosion；
（4）Clump weight lifting lug is bound with net cover eyelet is pre-tightened with steel wire is interspersed, is shunk since the axial tension of net cover pre-tightens, it can
To prevent in deepwater regions since hydraulic pressure leads to extra large cable radial contraction, the phenomenon that clump weight slides along extra large cable；
（5）It is screw thread that two halves clump weight, which is bonded semi circular surface with extra large cable, preferably can engage holding with preload net cover in this way.
Description of the drawings

Fig. 2 is the installation overall structure diagram of another embodiment of the present invention；
Fig. 3 is clump weight internal whorl of the present invention face structural schematic diagram；
Fig. 4 is the dynamic cable and flank fit structure schematic diagram of the present invention.
Specific implementation mode
Technical scheme of the present invention is described in further detail with reference to specific embodiment.
Embodiment 1
As shown in Figure 1, Figure 3 and Figure 4 shown in a kind of underwater dynamic cable clump weight, including two pieces close up to half structure, mutually match
Pouring weight ontology 1,1 inside axial direction of the counterweight block body, which is equipped with, accommodates the through-hole that dynamic cable 3 passes through, the counterweight block body
1 inside and 3 contact surface of dynamic cable are flank 2, the outside of the dynamic cable 3 be equipped be adapted with the flank 2 engage it is pre-
Tight net cover 4.
Preferably, in order to improve the whole antiseptic property of clump weight, the counterweight block body 1 using 316L stainless steels or its
He is made anti-corrosion material；Further, the outer application of the counterweight block body 1 has antifouling paint, can effectively provide and match
Weight and the corrosion for resisting seawater.
Preferably, it prevents in deepwater regions since hydraulic pressure causes extra large cable radial contraction, clump weight to show along what extra large cable slid
As occurring, lifting lug 6 is further fixed on the counterweight block body 1, the lifting lug 6 is connect by connecting line with net cover 4 is pre-tightened, described
Connecting line also may be used using finer wire or other connecting lines fitted through.
Embodiment 2
A kind of underwater dynamic cable clump weight as shown in Figure 2, Figure 3 and Figure 4, including two pieces close up to half structure, mutually match
Pouring weight ontology 1,1 inside axial direction of the counterweight block body, which is equipped with, accommodates the through-hole that dynamic cable 3 passes through, the counterweight block body
1 inside and 3 contact surface of dynamic cable are flank 2, the outside of the dynamic cable 3 be equipped be adapted with the flank 2 engage it is pre-
Tight net cover 4.As different from Example 1, it is additionally provided on the counterweight block body 1 and accommodates the through-hole that bolt 5 passes through, pass through bolt
5 fix the counterweight block body 1 mutually closed up, and structure is more firm.
The specific assembly method of the present invention is as follows：
（1）Net cover will be pre-tightened first to be sleeved in extra large cable, applies incipient extension power, it is made to generate the same of radial tightening convergent force
When, armouring protection can be played the role of to extra large cable；
（2）The cooperation of two halves clump weight is tightened with bolt, is bonded with net cover is pre-tightened, is pre-tightened net cover steel wire in this way and be embedded in double of counterweight
Block internal thread is generated with it and is engaged, and provides frictional force；
（3）Round lifting lug is welded on each clump weight；
（4）By the eyelet interspersed binding of finer wire of the lifting lug and preload net cover on clump weight, snakelike winding simultaneously tightens.
The underwater dynamic cable clump weight of the present invention, clump weight use 316L stainless steels, outer layer to coat antifouling paint, can be with
The effective corrosion that counterweight is provided and resists seawater；Clump weight and extra large cable binding face use flank, can preferably with preload
Net cover engagement is sturdy, effectively provides frictional force, prevents clump weight from being slid along extra large cable；Using finer wire by clump weight with
Net cover connection is pre-tightened, provides and tightens power, prevent clump weight from being slid along extra large cable.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, though
