Description of the drawings
In order that the present invention can be more clearly and readily understood, right below according to specific embodiment and in conjunction with attached drawing
The present invention is described in further detail, wherein
Fig. 1 is the structural diagram of the present invention.
Attached figure label is:
Power transmission cable core 1 leads insulated wire cores 11, buoyancy filler 12, tightens band 13, buoyancy liner 2, radial waterproof layer
3, anti-corrosion asphalt 4, oversheath 5, pulling force reinforcer 6, anti-corrosion winding rope 7, waterstop 8.
Specific implementation mode
(embodiment 1)
See Fig. 1, photovoltaic project suspension cable waterborne, include successively from the inside to the outside power transmission cable core 1, buoyancy liner 2,
Waterstop 8, radial waterproof layer 3, anti-corrosion asphalt layer 4, oversheath 5, pulling force reinforcer 6 and anti-corrosion winding rope 7.
Power transmission cable core 1 for insulated wire cores 11, buoyancy filler 12 and tightens band 13 from the inside to the outside;11 He of insulated wire cores
12 twisted synthesizing cable of buoyancy filler;Buoyancy filler 12 is round or fan-shaped.Insulated wire cores 11 are made of conductor and insulation, can be single
Or multicore, the insulated wire cores of midium voltage cable outer in insulation further include conductor shielding, insulation, insulation shielding, metallic shield, metal
Shielding uses copper strips or copper wire.Buoyancy filler 12 is a kind of light material that a kind of density is significantly smaller than water, such as inflation hair
Alveolitoid or skeletal support polyolefine material.
Buoyancy liner 2 is a kind of light material that a kind of density is significantly smaller than water.Buoyancy liner 2 is extruded in power transfer cable
The periphery of core 1 is made after band around the periphery of power transmission cable core 1.Buoyancy liner 2 plays so that cable has axis
To water-resisting ability, to prevent cable from surprisingly intaking, the invasion of water can be controlled the purpose in effective range.In extrusion type buoyancy
The wrapped band structure that blocks water outside liner layer, or in compound one layer of water blocking layer outside pouch-type buoyant belt material, blocked after playing water-swellable
Water is longitudinally extended problem.Buoyancy liner and the main buoyancy elements of buoyancy filler group cost cable, provide for cable and are suspended in
Buoyancy in water.
Each structure of cable is other than electrical, mechaincal wood considers, according to the demand for laying suspension function in the water of cable,
The buoyancy for needing to provide much abilities is to meet cable to be suspended in water surface key below.In every layer of structure of cable, electricity
Insulation system, anti-corrosion layer structure, outer jacket structure, the density of material of anti-corrosion winding rope structure of cable are close and close less than water
Degree can cancel this part-structure so being calculated to simplify, and be not involved in calculating, and emphasis calculates conductor structure, the gold of cable
Belong to caliber to waterproof construction, the density of material of pulling force reinforcement structure and volume.The thickness of buoyancy liner 2 is according to buoyancy liner 2
Volume conversion, the volume calculation formula of buoyancy liner 2 is:
Wherein, VIt is floatingFor the volume of buoyancy liner, after the volume for calculating buoyancy liner, by calculating power transmission cable core ruler
After very little, so that it may which the thickness for calculating buoyancy liner specifies the thickness of extrusion die or wrapped band by thickness;
ρIt is floatingFor buoyancy inner lining material density, this is material property, and the density of the material will be significantly smaller than the density of water, together
To the effect for providing buoyancy in water;
VWaterFor cable displacement of volume, be suspended in horizontal plane according to design cable hereinafter, and it is whole impregnate in water, so
Cable displacement of volume is exactly the volume of cable entirety;
ρWaterFor the density of water,
ViFor the volume of every layer of structure of cable,
ρiFor the density of every layer of structural material of cable;ρIt is floatingMuch smaller than ρWater。
Radial waterproof layer 3 is closing metal tube.It closes and semicircle phase cut type embossing, semicircle radius 5mm is set on metal tube
~8mm.Radial waterproof layer 3 plays waterproof effect, and according to the suspension function of cable, metal tube material is using the smaller aluminium of proportion
Or aluminum alloy materials.According to the requirement that cable is frequently bended caused by by wave in water, metal tube makes wrinkle shape.Wrinkle
There are cyclic annular crepe structure and spiral corrugated structure, wherein longitudinal fire resistance characteristic of cyclic annular crepe structure is stronger.Wrinkle shape is half
Circle phase cut type, and semicircle radius control, between 5mm~8mm, such structural cable can meet in water to be put as wave is bent
It moves without being damaged by external force.
Erosion resistant coating 4 is one layer of anti-corrosion asphalt of coating, and 10-20 parts of machine oil are added in plain asphalt, thus improve pitch
Plastic deformation ability prevent asphalt corrosion resistant layer from cracking during meeting cable bend and lose the anti-corrosion of water-proof metal layer
Ability.
Pulling force reinforcer 6 is that Young's modulus of the more uniform windings in 5 periphery of oversheath is not less than 500GPa glass fibres
Reinforced plastics round bar.With common steel wire ratio in cable have proportion it is small, the high feature of intensity, be suitble to water in suspension cable apply
If installation function requires, fixed cable position is played, the function of tension ability is provided.
Anti-corrosion winding rope 7 is polypropylene rope, and winding pitch is the diameter of polypropylene rope.And impregnate anti-corrosion asphalt by whole
Oversheath 5, pulling force reinforcer 6 and anti-corrosion winding rope overall fusion one are frequently bent by wave with to meet cable by processing
It is required that.O-hydroxyl-diphenyl ketone phenols UV absorbers are added in pitch simultaneously, can effectively improve the increasing of pitch anti-corrosion
Ageing resistance by ultraviolet light ability, while pitch anti-corrosion increases entirety and has wrapped up cable outer layer, has also effectively obstructed solar ultraviolet light to electricity
The ability of cable internal radiation protects the ageing resistance by ultraviolet light ability of cable.
Particular embodiments described above has carried out further in detail the purpose of the present invention, technical solution and advantageous effect
It describes in detail bright, it should be understood that the above is only a specific embodiment of the present invention, is not intended to restrict the invention, it is all
Within the spirit and principles in the present invention, any modification, equivalent substitution, improvement and etc. done should be included in the guarantor of the present invention
Within the scope of shield.
