Abstract
The invention discloses a submarine cable protection sleeve for an offshore wind driven generator. A submarine cable penetrates a first sleeve, a second sleeve and a third sleeve which are in sequential connection, wherein the first sleeve is a rigid pipe fixedly connected with a wind driven generator support frame; the second sleeve of which the surface is wrinkled is a flexible pipe. When seawater scours the submarine cable, the flexible second sleeve is subject to elastic bending, so that the submarine cable is prevented from damage caused by excessive bending, and the influence on the submarine from vortex street vibration generated by seawater is reduced at the same time.
Description
[technical field]
The present invention relates to offshore wind energy plant, particularly a kind of extra large cable protection sleeve pipe for offshore wind generating.
[background technology]
Along with the development of Oversea wind power generation, the problem of aspects such as wearing and tearing, bending is excessive all once appears in various degree at the external extra large cable of wind-driven generator of Europe and domestic marine wind field.How the external extra large cable protection of offshore wind generating is subjected to increasing attention.The extra large cable of traditional offshore wind generating is to pick out wind-driven generator by J-tube.Because seawater can wash away extra large cable and causes vortex street vibration effect, can continuous contact friction between extra large cable and J-tube, can occur wearing and tearing through the extra large cable in back after a while; And picking out near the spud leg with extra large cable, because scour hole appears in seawater scouring effect meeting, this can cause extra large cable unsettled, makes extra large cable overbending and impaired.
The present invention namely researchs and proposes a kind of extra large cable protection sleeve pipe for offshore wind generating at the deficiencies in the prior art.
[summary of the invention]
The present invention proposes a kind of extra large cable protection sleeve pipe for offshore wind generating; the sea cable passes first sleeve pipe that connects successively; second sleeve pipe and the 3rd sleeve pipe; first sleeve pipe adopts rigid pipe to fixedly connected with the wind-driven generator bracing frame; second sleeve pipe adopts flexible pipe; can be according to sea bed situation bending angle; transition is mild when making extra large cable insert the seabed from blower fan; prevent overflexing; can after appearring in seawater scouring, scour hole prevent curved protection to extra large cable; the appearance of second sleeve pipe is accordion ringwise; can avoid extra large cable excessive and impaired because bending, guarantee overbending does not take place when extra large cable is unsettled, reduce the vortex street vibration of seawater generation simultaneously to the influence of extra large cable.
For solving the problems of the technologies described above, a kind of extra large cable protection sleeve pipe for offshore wind generating of the present invention, adopt technical scheme as follows:
A kind of extra large cable protection sleeve pipe for offshore wind generating of the present invention; comprise first sleeve pipe that is fixedly connected on the wind-driven generator bracing frame; the described first sleeve pipe lower end is connected with second sleeve pipe; described another free end of second sleeve pipe is connected with the 3rd sleeve pipe; described first sleeve pipe is rigid pipe; described second sleeve pipe is flexible pipe; the described second sleeve pipe appearance is accordion ringwise; can avoid extra large cable excessive and impaired because bending; reduce the vortex street vibration of seawater generation simultaneously to the influence of extra large cable; described first sleeve pipe adopts metal material to make described the 3rd sleeve pipe rigid pipe or flexible pipe.
Described second sleeve pipe is corrugated flexible metal tube.
The elastic tube that described second sleeve pipe also can adopt the combination of rubber and flexible steel ring to make.
The elastic tube that described second sleeve pipe can also adopt polyurethane to make.
A kind of extra large cable protection sleeve pipe for offshore wind generating of the present invention; the sea cable passes first sleeve pipe, second sleeve pipe and the 3rd sleeve pipe that connects successively; first sleeve pipe adopts rigid pipe to fixedly connected with the wind-driven generator bracing frame; second sleeve pipe adopts flexible pipe; the appearance of second sleeve pipe is accordion ringwise; can avoid extra large cable excessive and impaired because bending, reduce the vortex street vibration of seawater generation simultaneously to the influence of extra large cable.

[embodiment]
Below in conjunction with accompanying drawing embodiments of the present invention are elaborated.
A kind of extra large cable protection sleeve pipe for offshore wind generating of the present invention; comprise first sleeve pipe 1 that is fixedly connected on the wind-driven generator bracing frame 4; described first sleeve pipe 1 lower end is connected with second sleeve pipe 2; described second sleeve pipe, 2 another free ends are connected with the 3rd sleeve pipe 3; described first sleeve pipe 1 is rigid pipe, and described second sleeve pipe 2 is flexible pipe.The sea cable passes first sleeve pipe 1, second sleeve pipe 2 and the 3rd sleeve pipe 3, the first sleeve pipes 1 successively and adopts rigid pipe with convenient fixedly connected; Second sleeve pipe 2 adopts flexible pipe, and the appearance of second sleeve pipe 2 is accordion ringwise, when seawater scouring, can produce the elasticity bending, avoids inner extra large cable to damage because bending excessively.
Described first sleeve pipe 1 is fixedlyed connected by flange 11 with wind-driven generator bracing frame 4, and described first sleeve pipe 1 adopts metal material to make described the 3rd sleeve pipe 3 rigid pipes or flexible pipe.
In the present invention, described second sleeve pipe 2 can adopt corrugated flexible metal tube, and corrugated flexible metal tube tool better elastic has anti-resistance to compression and corrosion resistant characteristics simultaneously.
The elastic tube that second sleeve pipe 2 of the present invention also can adopt the combination of rubber and flexible steel ring to make, the elastic tube that perhaps adopts polyurethane to make.
