Description
Technical field
The utility model, which belongs to, also wants auxiliary accessories technical field, and in particular to a kind of underwater dynamic cable clump weight.
Background technique
Dynamic sea cable itself will cause biggish 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, vulnerable to external force and sea cable
Slippage is generated, finally sea cable is damaged, influences service life；Under deepwater regions, since hydraulic pressure causes sea cable radially to be received
Contracting, clump weight easily slide along sea cable axial position.
Utility model content
Purpose of utility model: purpose of the utility model is to solve deficiencies in the prior art, provide a kind of underwater
Dynamic cable clump weight while generating radial tightening convergent force to sea cable, plays the role of armouring protection.
Technical solution: a kind of underwater dynamic cable clump weight described in the utility model, including two pieces to half structure, mutually
The counterweight block body closed up, the clump weight body interior axial direction, which is equipped with, accommodates the through-hole that dynamic cable passes through, the counterweight
Be flank with dynamic cable contact surface on the inside of block body, be equipped on the outside of the dynamic cable be adapted with the flank engage it is pre-
Tight net cover.
Further, the counterweight block body is made of 316L stainless steel 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 by connecting line and pre-tightens net cover company
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.
The utility model has the advantages that the beneficial effects of the utility model are as follows:
(1) while the preload net cover arranged can generate radial tightening convergent force to sea cable, play the role of armouring protection；
(2) layout of distributed clump weight can prevent submerged cable floating or deviate designated position, make sea cable according to pre-
First setting line style operation；
(3) clump weight uses 316L stainless steel, and outer layer coats antifouling paint, can effectively provide counterweight and resist seawater
Corrosion；
(4) it by clump weight lifting lug and the interspersed binding of steel wire of preload net cover eyelet, is received since the axial tension of net cover pre-tightens
The phenomenon that contracting, can prevent in deepwater regions since hydraulic pressure leads to sea cable radial contraction, and clump weight slides along sea cable；
(5) it is screw thread that two halves clump weight, which is bonded semi circular surface with sea cable, can preferably engage embrace with preload net cover in this way
Tightly.
Detailed description of the invention
Fig. 1 is the installation overall structure diagram of the utility model one embodiment；
Fig. 2 is the installation overall structure diagram of another embodiment of the utility model；
Fig. 3 is the utility model clump weight internal whorl face structural schematic diagram；
Fig. 4 is the dynamic cable and flank fit structure schematic diagram of the utility model.
Specific embodiment
Technical solution of the present invention is described in further detail combined with specific embodiments below.
Embodiment 1
A kind of underwater dynamic cable clump weight shown in as shown in Figure 1, Figure 3 and Figure 4, including two pieces closed up to half structure, mutually
Counterweight block body 1, the 1 inside axial direction of counterweight block body, which is equipped with, accommodates the through-hole that passes through of dynamic cable 3, the clump weight
1 inside of ontology is flank 2 with 3 contact surface of dynamic cable, is equipped with to be adapted with the flank 2 on the outside of the dynamic cable 3 and engage
Preload net cover 4.
Preferably, in order to improve the whole antiseptic property of clump weight, the counterweight block body 1 using 316L stainless steel 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 leads to sea cable radial contraction, clump weight shows along what sea 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 can also 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 closed up to half structure, mutually
Counterweight block body 1, the 1 inside axial direction of counterweight block body, which is equipped with, accommodates the through-hole that passes through of dynamic cable 3, the clump weight
1 inside of ontology is flank 2 with 3 contact surface of dynamic cable, is equipped with to be adapted with the flank 2 on the outside of the dynamic cable 3 and engage
Preload net cover 4.Unlike the first embodiment, it is additionally provided on the counterweight block body 1 and accommodates the through-hole that bolt 5 passes through, passed through
The fixed counterweight block body 1 mutually closed up of bolt 5, structure are more firm.
The specific assembly method of the utility model is as follows:
