Description

Deep sea cable
Technical field
The utility model relates to the rope field, relates in particular to in the ocean, boats and ships being carried out the deep sea cable of location, deep-sea or are used for deep sea cable mobile, anchor stone exploration activity drilling platforms.
Background technology
Existing deep sea cable is made of wire rope core and wrap, and wherein, wire rope core is to be formed by multiply cordage twisting or braiding, and wrap is the tube-in-tube structure that is formed by the braiding of multiply cordage, and wrap is set on wire rope core and wraps wire rope core.In use, the grit in seabed and seawater enters between wrap and wire rope core through the braiding hole on wrap, even enters into wire rope core inside.Like this, when using this deep sea cable, the grit that enters deep sea cable respectively with the cordage phase mutual friction that forms wire rope core and wrap, the cordage that causes consisting of wire rope core and wrap is worn and even rubs, and then cause wire rope core and wrap breakage, greatly shortened the service life of deep-sea cable.
In addition, in use, seawater immerses in deep sea cable, has increased the weight of deep sea cable at the state of use, causes using inconvenience.After deep sea cable being picked up from seawater and dry, deep sea cable is corroded in the crystallization on deep sea cable of the inorganic salts such as sodium chloride and potassium chloride, and then affects the service life of deep sea cable.
As seen, existing deep sea cable is short service life, and uses inconvenient.
The utility model content
For solving short and inconvenient problem with use in existing deep sea cable service life, the utility model proposes a kind of deep sea cable, comprise wire rope core and wrap, be provided with anti-particulate layer between described wire rope core and described wrap, should comprise one deck winding layer at least by anti-particulate layer, this winding layer presses folded be wrapped in described wire rope core on to form by spiral around the volume mode by a waterproof antiwear material webs.Like this, when using this deep sea cable, grit in seabed or seawater is after the braiding hole on wrap enters deep sea cable, because anti-particulate layer stops and can't contact with wire rope core, more can not enter into wire rope core inside, can avoid wire rope core because wearing and tearing with the mutual friction of grit phase, extend the service life of deep sea cable; Anti-particulate layer is made by the waterproof antiwear material webs, can reduce the seawater amount that is immersed in deep sea cable, both alleviate the corrosion of the inorganic salts in the seawater to deep sea cable, further extend the service life of deep sea cable, alleviated again the weight of the deep sea cable that is in the use state, the convenient use.
Preferably, the diameter of described deep sea cable is D, and when 80mm≤D≤160mm, the thickness of described anti-particulate layer is H Anti-, and 4mm≤H Anti-≤ 6mm; When 160mm＜D≤260mm, the thickness of described anti-particulate layer is, and 6mm＜H Anti-≤ 10mm.Like this, both can avoid the grit that entered between wrap and anti-particulate layer by the braiding hole on wrap too thin with its worn out service life that affects deep sea cable because of anti-particulate layer, can avoid again causing using inconvenience because of the anti-too thick diameter that affects deep sea cable of particulate layer.
Preferably, the width L of described waterproof antiwear material webs is 30cm-60cm, and thickness h is 2mm-5mm.Like this, both be convenient to the waterproof antiwear material webs is pressed folded being wound on wire rope core by spiral around volume, can have reduced around the volume number again, reduced the manufacturing cost of deep sea cable.Further, the width of the folded band of the pressure in described winding layer is w, and 10mm≤w＜L.Like this, can avoid in winding layer consisting of and press two adjacent endless belt of folded band to form the separation breach because of stressed separation, and then avoid grit to enter between anti-particulate layer and wire rope core through separating breach, even enter into wire rope core inside, wire rope core is caused wearing and tearing, extended the service life of deep sea cable.
Preferably, when described anti-particulate layer was made of the winding layer more than two-layer, the winding direction of adjacent two-layer winding layer was opposite.Like this, can increase and prevent that the particulate layer is wrapped in the tightness on wire rope core, avoid producing and separate breach, extend the service life of deep sea cable.
Preferably, the sealed at both ends waterproof antiwear material webs that is enclosed with of described wire rope core.Like this, can avoid seawater to enter wire rope core, and then avoid the inorganic salts corrosion wire rope core in seawater, extend the service life of deep sea cable.
Preferably, described wire rope core is formed by three strands or 12 bursts of cordage twistings or braiding.Like this, can increase the force intensity that is subjected to of wire rope core, and then increase the force intensity that is subjected to of deep sea cable.
Preferably, when the span of the diameter D of described deep sea cable was 80mm≤D≤160mm, the thickness of described wrap was H Bag, and 6mm≤H Bag≤ 8mm; When the span 160mm of the diameter D of described deep sea cable＜D≤260mm, the thickness of described wrap is H Bag, and 8mm＜H Bag≤ 10mm.Like this, both can avoid easily being worn and torn by grit because wrap is too thin affects the service life of deep sea cable, can avoid again causing the diameter of deep sea cable excessive because wrap is too thick, and impact is used.Further, described wrap is formed by 40 stereotyped writing cordage braidings.Like this, can reduce the count of wrap with the proportion of reduction wrap and wire rope core, and then reduce the manufacturing cost of deep sea cable.
Description of drawings
Fig. 1 is the perspective view that the utlity model has the deep sea cable of three strands of structure wire rope cores and one deck winding layer;
