Technical field
A kind of laying apparatu of high-voltage undersea cable is the utility model is related to, belongs to the Oversea wind of regenerative resource industry
Power field.
Background technology
The energy is the basis of human social development, and the renewal of energy technology and the change of variety of energy sources decide human society
The property and mode of development.Oversea wind power generation is an emerging industry, has significant society and environmental benefit, for pushing away
Dynamic China's Renewable Energy Development important in inhibiting.
China starts progressively to develop Oversea wind power generation after 2007, and China is completed multiple marine wind electric field items at present
Mesh.The traditional marine wind electric field transmitting system in China, send to land using more times 35kV submarine cables.The seabed electricity of 35kV
Cable is laid using cable ship, and using height frame back twist technology back twist, mole plough excavates cable duct.
With the development of China's Oversea wind power generation industry, marine wind electric field offshore distance is more and more remote, wind power plant scale
It is increasing, it is necessary to high-voltage undersea cable using 220kV voltage class.220kV high-voltage undersea cables have that diameter is big, weight
Greatly, length is long and the features such as buried depth is big, and it is also big compared with traditional 35kV cables that it lays difficulty.Due to 220kV high-voltage undersea cables
Diameter is big, radius of turn is big, and traditional height frame back twist technology has been unable to meet back twist demand, and may cause the torsion of cable
Song damage.Since 220kV high-voltage undersea cable weight is big, buried depth is big, the cutting depth of traditional mole plough excavation technology, to sea
The adaptability and continuous-running efficiency of bed soil matter can not meet the laying requirement of 220kV high-voltage undersea cables.
The content of the invention
The technical problems to be solved in the utility model is：There are problem for above-mentioned, there is provided one kind is adapted in a variety of seas
The laying apparatu of the high high-voltage undersea cable of bed soil matter, continuous-running efficiency, it is intended to meet major diameter, big weight, long range, big
The laying requirement of buried depth cable.
Technical solution is used by the utility model：A kind of laying apparatu of high-voltage undersea cable, has barge, barge
Afterbody is equipped with gantry crane, through winch pendant cables burying machine on gantry crane, it is characterised in that：The barge is equipped with cable back twist disk,
Cable leading truck is equipped with the barge, between cable back twist disk and cable burial machine successively and cable is auxiliary send device；Wherein cable moves back
Turn round disk and use electric rotary-type cable reel, cable is auxiliary to send utensil to have a stretcher, and the cable on cable back twist disk is led through cable successively
The cable burial machine is delivered to after to frame, the auxiliary stretcher sent in device of cable.
The cable leading truck, which has from the cable back twist disk, extends to the auxiliary roller conveying apparatus for sending device of the cable,
And the roller conveying apparatus send device end to tilt from cable back twist disk end to cable is auxiliary.
The cable burial machine front end sets two HP jetting pumps.
The diameter of the cable back twist disk is more than 20 times of cable size.
The cable is auxiliary to send utensil to have stretcher, is adapted to the cable of various specifications.
The beneficial effects of the utility model are：1st, cable back twist disk uses electric rotary-type back twist disk in the utility model,
Major diameter, the back twist needs of big weight cable are adapted to, ensure that cable is not twisted in laid processes；2nd, cable is auxiliary send utensil
There is stretcher, be adapted to the cable of various specifications, on the premise of enough tractive force is ensured, excessive side is not caused to cable
To pressure；3rd, cable burial machine uses high compression injection techniques ditching, is adapted to the various soil properties such as mud, silt, flour sand, chiltern
Sea bed, and cable is laid with ditching, operating efficiency is high.
Brief description of the drawings
Fig. 1 is the structure diagram of embodiment.
Embodiment
As shown in Figure 1, the present embodiment is a kind of laying apparatu of high-voltage undersea cable, there is barge 5, be provided with barge
Cable back twist disk 1, cable back twist disk to barge afterbody is equipped with cable leading truck 2 and cable transfer device 3, barge successively on the barge
Afterbody is equipped with gantry crane 6, through winch pendant cables burying machine 4 on gantry crane.
Cable leading truck 2, which has from cable back twist disk 1, in this example extends to the auxiliary roller conveying apparatus 21 for sending device 3 of cable,
And the roller conveying apparatus send device end to tilt from cable back twist disk end to cable is auxiliary, and roller conveying apparatus 21, which is equipped with, limits electricity
The guiding mechanism of cable conveying direction.There are roller conveying apparatus 3 seat supports framves to support 211,3 seat supports framves from cable back twist disk 1
Holding to cable is auxiliary send 3 end of device to be arranged in order from high to low, in the fixation of supporting rack 211 and 5 deck of barge, and through steel wire rope and deck
Connection is fixed.
The highest supporting rack bottom installation cable back twist disk 1 in 3 seat supports framves 211, cable back twist disk is used using electricity
Dynamic rotary cable disk, back twist disk diameter should be greater than 20 times of cable size, be adapted to the back twist of major diameter, big weight cable
Need, ensure that cable is not twisted in laid processes.
Stretcher and the delivery wheel composition that cable transfer device 3 is hydraulically operated in the present embodiment, spacing, the pressure of stretcher
It can be adjusted according to cable size, pattern, to adapt to the cable of various specifications, on the premise of enough tractive force is ensured, not to electricity
Cable causes excessive lateral pressure.During cable laying, stretcher makes cable keep certain pulling force, prevents cable from spreading
If due to self gravitation during, trend and stormy waves etc. influence to be slid by barge, cause the cable in process of deployment to injure.
This example is equipped with HP jetting pump in cable burial machine front end, using high compression injection techniques ditching.
The operation principle of the present embodiment is as follows：Cable extends upwardly to cable leading truck 2 from cable back twist disk 1, and along electricity
Cable leading truck send device 3 to cable is auxiliary diagonally downward, through cable is auxiliary send device after be delivered to the cable burial being lowered on sea bed face
Machine 4, the cable chamber for eventually passing through cable burial machine are routed to sea bed face.
After cable burial machine 4 transfers to sea bed face by gantry crane 6, start HP jetting pump, high pressure water, which enters, buries cable machine high pressure
Water cavity, high pressure water are ejected by high-pressure nozzle, and the sea bed face below impact cable burial machine paving cable colter, forms trench, paving
Cable colter sinks to trench under the action of dead weight, spacing by adjusting deep-controlled bar, stops when colter reaches set depth
Sink.Depth detection equipment detection at this time buries cable depth and reaches requirement, and barge starts strand anchor and moves ahead, and cable buries cable machine in barge
Traction is lower slowly to move ahead along route, and cable is routed in the trench dug.
Certainly, described above is not limitation of the utility model, and the utility model is also not limited to the example above, this skill
The those of ordinary skill in art field, in the scope of the utility model, change, addition or the replacement made, should all belong to this reality
With new protection domain.
