Description
Technical field
The utility model relates to a kind of transmission cable, relates in particular to a kind of floatability or is suspended in cable in the water.
Background technology
Survey under water, field such as salvaging, need electric power and command signal etc. be transferred to machine and equipment under water with cable, because the total body density of normal cable is much larger than water, the deadweight of these transmission cables causes its sinking, when equipment with install chin-deep under water, cable is very long, and its down force will cause the cable connection place fracture on bank base or the boats and ships or even cause cable itself to rupture.Underwater installation because the friction between the sinking cable and the water-bed face of land makes equipment move difficulty, and causes cable jacket to break easily, causes accident such as electric leakage and distorted signals under water when mobile simultaneously.Common cable is not sunk, and the early stage main external floatation thing that relies on makes cable float on the water surface.
How to reduce the down force of cable in water, cable be need not by means of any external floatation thing, can overcome deadweight and floating or in water, freely suspends at the water surface, i.e. exploitation so-called " buoyant cable ", be under water, surface facilities use in the key issue of necessary solution.
Buoyant cable is promptly inserted proportion less " floating core group " or " foaming body " in cable, thus the whole proportion that makes cable less than or approach water.When such cable is used for the power set of operation at sea or sniffer, can directly swim in waterbornely, appearance is high-visible, is convenient to safeguard; When being used for the stube cable of the trailing cable of submarine, mine sweeper or habitata, it is freely suspended in water.
Submarine is first elected in buoyant cable application militarily, uses towing buoyancy antenna and two kinds of dedicated antenna of towing buoy antenna to receive on the submarine and transmits.The trailing cable of towing buoyancy antenna and towing buoy antenna is exactly a buoyant cable, and the length of towing buoyant cable reaches 500 meters.Submarine also has the towing line array sonar of mainly being made up of buoyant cable, is used for monitoring, monitoring other submarines and surface ship.Surface ship also must be used buoyant cable, its towing line array sonar promptly is that hydrophone is embedded in the linear array that forms on the buoyant cable, drag behind the naval vessels tail in the water by the towing buoyant cable, its total length reaches 1000 to 2000 meters, be mainly used in long-range audiometry submarine noise, and monitor, direction finding and identification, thereby improve surface ship antisubmarine reconnaissance ability.Mine sweeper also needs to use buoyant cable, and the minesweeping gear of various generation acoustic pressures, magnetic field and water pressure sensing is installed on the towing buoyant cable behind its ship, ignites submarine mine thereby produce acoustic pressure, magnetic field and variation in water pressure away from hull during clearance.
Civilian aspect, 1000 meters underwater robots to 6000 meters work below the water surface rely on high-intensity floating composite cable, and the transmitted in both directions of electric power and control signal and data-signal is provided between itself and lash ship.Fields such as drilling at the sea, oil platform, marine seismic prospectiong and ocean power generation also need a large amount of buoyant cables.Swimming pool, waterworks and other automatic pollutant removal/cleaning equipment etc. in place under water need buoyant cable that electric power support and signal instruction are provided.In a word, buoyant cable is all having great demand aspect the army and the people two, and according to incompletely statistics, about 100,000 kilometers of annual requirement is worth 30 to 5,000,000,000 yuans, and every year is with about 12% speed increment.
Buoyant cable is a kind of special cable, domestic Tianjin No.609 Electric Cable Co., Ltd., Jiangsu friend really company such as friendship cable Co., Ltd and Zhengzhou cable group has carried out exploitation and small lot test manufacture, is respectively applied for submarine cable burying machine, operation at sea power set and sniffer, contactless electromagnetism is swept (water) thunder ship etc.Along with day by day increasing of ocean development, the various water surface/underwater operations, and the development of technology such as Oversea wind power generation, tidal power generation, the buoyant cable market capacity will enlarge rapidly, and increasing electric wire factory has added development and produced the ranks of such cable.
The most employing of the product that these enterprises produce is implanted polyethylene foamed/polyacrylic method and is made between cable center or core and sheath, such buoyant cable pliability is poor, and the bending curvature radius is big, and operability is poor; For frequent folding and unfolding of needs and the occasion that moves around among a small circle, its frequently twist and and hull, embankment or the hard thing of cable periphery between scraping, cause the cable premature breakage, thereby reduce useful life.
For buoyant cable, to bear the performance requirements such as stretching and frequent bending except that meeting common flexible cable, key is that cable must swim on the water surface, promptly the global density of cable should be less than 1.0g/cm
3As everyone knows, the density of metallic conductor, insulator and sheath material has determined the global density of common flexible cable, and the global density of general cable is all greater than 1.0g/cm
3, and in rising trend with the long-pending increase of the cross-section of cable.In addition, though the operating voltage of buoyant cable is not high, operating current is bigger, to having relatively high expectations of insulation and sheath, therefore can not blindly reduce the density of insulating barrier and restrictive coating, otherwise can cause insulating and the physical and mechanical properties of sheath descends, influence the overall performance of cable.So reduce the total body density of cable, mainly by realizing in the inner density materials with smaller promptly so-called " floating core group " that adds of cable.
