Abstract
The invention discloses a heavy-load shallow-draft wind power cable ship which is further capable of adapting to construction in an intertidal zone of shoal water besides the functions of the common large-displacement deep water cable ship. As a ship body is large, the cable ship is high in load capacity and good in stability and can adapt to cable laying in a coastal abyssal region; and as the ship body is wide, the cable ship has shallow draft with light load; besides, in combination with a special structure at the bottom of the ship body, the cable ship is capable of realizing shallow bottom sitting, and thus the survival capability of the cable ship in the intertidal zone is improved; and a cable laying system with an automatic cable demounting and demounting capability is employed.
Description
Technical field
The present invention relates to a kind of ocean engineering equipment technology that is used for marine cabling, especially a kind of heavily loaded shallow draft wind-powered electricity generation cable ship that is applicable to the coastal waters cabling.
Background technology
Wind energy is the regenerative resource of cleaning, and wind-power electricity generation is that technology is the most ripe in the new energy field, one of generation mode of exploitation condition on the largest scale and commercialized development prospect.Wind-powered electricity generation generating capacity in the world's is with average annual speed increment more than 30% in recent years.China's seashore line length, the marine site is vast, and the coastal waters wind energy resources is abundant, and simultaneously, the coastland is economically developed, and power demand is big.Development and use offshore wind farm resource for satisfying Electricity Demand, is improved energy mix, reduces environmental pollution, and the reply Global climate change promotes that economic sustainable sound development is significant.
Power cable between wind farm grid-connected cable and island lays the ship type and mainly contains two kinds at present.First kind is that technology gobbles depth of water water cable ship than advanced big displacement, constructs because of factors such as stranded or propulsion coefficient can not get into shallow water area, and second kind then is the float water yield level land ship that absorbs water cabling specially at shallow water.This ship type general technology is more backward, and constraint conditions such as load carrying ability make operating efficiency low, does not have the existing dynamic positioning of a Equipment of Vessel so far, not only deepwater work is arranged but also can sit the bottom application worker.
Summary of the invention
The present invention is directed to the prior art deficiency; Provide a kind of can abyssal zone construction again can be in the shoal water zone ship type of the cable installatition of construction; Refer in particular to and to have good cabling efficient and stability in deepwater regions, can and can implement the heavily loaded shallow draft wind-powered electricity generation cable ship at the end sat of the task of laying in very shallow waters existence again.
The present invention adopts following technical scheme to realize:
A kind of heavily loaded shallow draft wind-powered electricity generation cable ship comprises hull, and hull comprises stem, and the ship stern is characterized in that: said hull is a catamaran hull, and the aspect ratio of hull is less than 3:1; The hull least draft degree of depth is less than 1.5 meters.
Said hull top is provided with the rotation type cable tank, and this rotation type cable tank comprises the axis of rotation of vertical setting and drives the driving arrangement that the axis of rotation rotates, is positioned at the one side setting of rotation type cable tank and leads the cable frame.
Said hull comprises base plate, on this base plate groove is set, and groove is for vertically being interspersed or the distribution of square body length direction.
The ship stern adopts the two oar devices of two-shipper, and promptly ship stern symmetric position is provided with two main thrusters.
Ship stern midway location is provided with the stern thruster, and stem is provided with two bow thrusters.
Beneficial effect of the present invention is:
1. in the shoal water zone, roomy hull makes and under identical load-carrying, reduces draft as far as possible, guarantees the cabling operation under the less condition of the depth of water; Simultaneously, in the abyssal zone, roomy hull can increase load carrying ability again, delivers more extra large cable, improves the continuity and the operating efficiency of construction operation, and bigger freeboard improves capacity of anti-storm, improves the engineering ability to ward off risks;
The present invention can sit end characteristics improve ship in the shoal water zone viability, and improve operating efficiency; Adopt groove and water spray, the jet desliming technology that combines at sea on the wind-powered electricity generation cable ship hull, solve under the extreme water level condition, the cable ship of seat at the end plays floating problem again;
3. effectively connect deep water and subfluvial cable lays, reduce marine cable joint quantity, save the cable junction production time, improve operating efficiency, improve the transmission of electricity safety simultaneously;
4. can accomplish big depth of water scope inner cable with a ship and lay task, need not other auxiliary vessels, reduce executive cost, alleviate interference and destruction simultaneously environment;
5. adopt the rotation type cable tank, solved major diameter triple cable back twist problem effectively, improve cabling efficient simultaneously.

The specific embodiment
Specify the specific embodiment of the present invention below in conjunction with accompanying drawing.
Like Fig. 1; This ship relies on roomy hull and boats and ships to sit end technology and combines, and hull preferably adopts the roomy type ship body of aspect ratio less than 3:1, and the least draft degree of depth can be less than 1.5 meters; Guarantee to implement the cabling engineering at shallow water area; When the depth of water at ebb tide less than least draft, ship gets into supported on the seabed condition, waits for that flood tide to continue operation.
Be provided with groove in order to improve hull desliming effect hull base plate; Groove is provided with two kinds of different schemes; See that Fig. 5 groove for vertically being interspersed or seeing that Fig. 6 square body length direction distributes, takes all factors into consideration desliming efficient and wherein a kind of scheme arrangement is adopted in the requirement of structure.Desliming technology such as the while combines at the groove place to spray water, jet improve the desliming effect, solve under the extreme water level condition, and the cable ship of seat at the end plays floating problem again.
Like Fig. 1 and Fig. 2, this ship adopts high-power rotation type cable tank, when the loading vessel cable cable tank through the actuating device left-hand revolution, then opposite action during the cabling operation.Whole reprinting stores and the central cable of laid processes does not have any axial twist distortion.The colleague improves the efficient and the cabling efficient of loading and unloading cable, has solved the back twist problem of major diameter triple cable simultaneously.
Like Fig. 3 and Fig. 4, this ship adopts the two oar propulsion modes of two-shipper, the cabling job execution navigation when guaranteeing designed draft; Further, at the ship stern stern thruster is set, stem is provided with two bow thrusters, improves the nimble property and the dynamic positioning efficient of hull operation, guarantees the accuracy of location simultaneously.Reduce the diameter of screw propeller as far as possible, adapt to than shallow draft.
