Description
Technical Field
The invention relates to the technical field of marine cables, in particular to a marine cable for preventing seawater vapor erosion for a ship.
Background
A cable is a power or signal transmission device, usually consisting of several or several groups of conductors, shaped like a rope, usually twisted from several groups of conductors, insulated from each other and usually twisted around a center, the whole being covered with a highly insulating covering.
In the environment and field of application of the cable, the cable for ships includes a power cable for ships, a power cable for power, lighting, control and communication transmission for various ships in river and sea and offshore or offshore structures, and the power cable, the control cable for ships, the communication cable for ships and the like are included. Usually, the cable for ship has limited laying space, so the armor structure adopts the metal wire weaving mode, which is the biggest difference from the land common power, control and communication cable in structure
In marine cables, the using amount and the demand amount are relatively large, particularly for ships sailing at sea, the ships run at sea for a long time, sea water vapor generated by waves and sun exposure can fill the whole ships, various equipment soaked in the sea water vapor for a long time can be corroded by the sea water vapor, particularly in the aspect of electricity utilization of the ships, once the cables are corroded and damaged, the danger of electric leakage is likely to occur, particularly in the environment with high humidity in the ships, once the cables are corroded and damaged, not only can the normal operation of the ships be influenced, but also the danger of electric shock of accompanying personnel can occur, and therefore how the marine cables are resistant to corrosion in the environment filled with the sea water vapor is an important factor for ensuring the normal operation and safety of the ships.
The main improvement of the high-temperature-resistant, corrosion-resistant and high-voltage-resistant flexible cable (patent No. CN1929042B) disclosed in Chinese patent is that the insulation, shielding base material and sheath of the cable are made of silicon rubber, wherein the insulation and shielding base material is made of methyl vinyl silicon rubber, and then fine copper wire stranded conductors and a braided net are used for shielding, so that the flexibility, temperature resistance, corrosion resistance and voltage resistance of the cable are all coordinated and improved. The high-temperature-resistant, corrosion-resistant and high-voltage flexible cable is characterized in that the conductor is a fine copper wire stranded flexible conductor, the insulating, semi-conducting and insulating conductor shields and the insulating shield base material are methyl vinyl silicone rubber, the conductor shields, the insulating and the insulating shields are extruded at one time, the metal shield is a fine copper wire woven mesh, and the outer sheath is a silicone rubber or polytetrafluoroethylene sheath;
for example, the moisture-proof and corrosion-proof coaxial cable disclosed in the Chinese patent (patent No. CN103354124A) adopts a new self-prepared mineral oil corrosion-proof mixture to replace the original ointment, and is filled between an outer conductor and a sheath, so that the moisture-proof and corrosion-proof coaxial cable has excellent corrosion resistance, solves the problem of compatibility with a cable sheath material, and is not influenced in transmission performance.
The technical scheme is that the currently adopted mode is improvement on the use of a coating, a filler and a material, and although the improvement is carried out for the purpose of corrosion prevention, the defects exist, for example, the development cycle and the development cost of a new material cannot be controlled, and although the material has a certain corrosion resistance effect, the material cannot resist the corrosion of strong sea wind and sea water vapor for a long time in the full environment of sea water vapor filling, the final corrosion prevention effect is still required to depend on external device protection and artificial maintenance operation, the coating and the material can only carry out corrosion prevention within a certain time, and the time limitation is large.
In the marine cable, the use and demand are relatively large, especially in a ship sailing at sea, the ship runs at sea for a long time, sea water vapor generated by waves and sun exposure can fill the whole ship, various equipment soaked in the sea water vapor for a long time can be eroded by the sea water vapor, especially in the aspect of ship electricity utilization, once the cable is eroded and damaged, the risk of electric leakage is likely to occur, especially in the environment with high humidity in the ship, once the cable is eroded and damaged, the normal operation of the ship can not only be influenced, and even the risk of electric shock of accompanying personnel can occur, so that how the marine cable resists erosion in the environment filled with the sea water vapor is an important factor for ensuring the normal operation and safety of the ship.

In this embodiment, adopt split type equipment mode design, mainly be equipment operation in the time of conveniently producing the cable, and simultaneously, multistage formula choked flow ring 601 and the design of top layer lag 1, the design of spacing 602 grafting entering top layer lag 1 inner chamber is being coordinated simultaneously, on the one hand in the production suit top layer lag 1 the time, because 1 length of top layer lag is by the segmentation design, realization suit work that can be better, spacing 602 grafting entering top layer lag 1 inner chamber in both ends can carry out the position compensation of confined space for cable top layer lag 1 expend with heat and contract with cold, avoided the cable to take place the tensile problem emergence that produces deformation influence whole quality in top layer.
Wherein, the inner cavity of the limit strip 602 is provided with a plurality of wire core holes 605 at equal intervals, and the middle part of the outer wall of the limit strip 602 is fixedly welded with the inner wall of the rotary limit ring 606.
In this embodiment, the cable core hole 605 directly restricts the positions of a plurality of internal cables one by one at the cable end, so as to ensure that the plurality of cables inside the cable are prevented from being wound together, and each section of cable is provided with a limiting strip 602, so that the heat exchange capacity of the marine cable can be enhanced section by section.
Wherein both ends of the thread deep groove 101 face the inclined surfaces of the spoiler blades 603.
In this embodiment, when vortex flabellum 603 receives sea wind pivoted time, wherein vortex flabellum 603 rotates the port department of screw thread deep trouth 101 at every turn, cold wind that vortex flabellum 603 brought just can directly enter into screw thread deep trouth 101 inner chamber and along screw thread deep trouth 101 constantly motion gradually from the port department, reduces the volume of sea water steam adhesion on the cable outermost surface on the one hand, can also carry out the heat exchange through continuous cold wind laminating cable motion simultaneously, real-time incessant to the cable.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
