Abstract
The utility model discloses a submarine cable protective 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, and 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 utility model relates to offshore wind energy plant, particularly a kind of extra large cable protection sleeve pipe of offshore wind generating.
[background technology]
Along with the development of Oversea wind power generation, in Europe and the external extra large cable of wind-driven generator of domestic marine wind field all once there are in various degree wearing and tearing, bent the problem of the aspect such as excessive.How the external extra large cable protection of offshore wind generating is subject 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 and cause vortex street vibration effect extra large cable, can continuous contact friction between extra large cable and J-tube, through extra large cable after a period of time, there will be wearing and tearing; And picking out near spud leg with extra large cable, because seawater scouring effect there will be scour hole, this can cause extra large cable unsettled, makes extra large cable overbending and impaired.
The utility model researchs and proposes a kind of extra large cable protection sleeve pipe of offshore wind generating for the deficiencies in the prior art.
[utility model content]
The utility model proposes a kind of extra large cable protection sleeve pipe of offshore wind generating, sea cable is through the first sleeve pipe connecting successively, the second sleeve pipe and the 3rd sleeve pipe, the first sleeve pipe adopts rigid pipe to be fixedly connected with wind-driven generator bracing frame, the second sleeve pipe adopts flexible pipe, can be according to sea bed situation bending angle, while making extra large cable from blower fan access seabed, transition is mild, prevent overflexing, can after appearring in seawater scouring, scour hole carry out anti-bending protection to extra large cable, the appearance of the second sleeve pipe is accordion ringwise, can avoid extra large cable excessive and impaired because bending, guarantee not occur when extra large cable is unsettled overbending, the vortex street that simultaneously reduces seawater generation vibrates the impact on extra large cable.
For solving the problems of the technologies described above, the extra large cable protection sleeve pipe of a kind of offshore wind generating of the utility model, adopts technical scheme as follows:
The extra large cable protection sleeve pipe of a kind of offshore wind generating of the utility model, comprise the first sleeve pipe being fixedly connected on wind-driven generator bracing frame, described the first sleeve pipe lower end is connected with the second sleeve pipe, described another free end of the second sleeve pipe is connected with the 3rd sleeve pipe, described the first sleeve pipe is rigid pipe, described the second sleeve pipe is flexible pipe, described the second sleeve pipe appearance is accordion ringwise, can avoid extra large cable excessive and impaired because bending, the vortex street that simultaneously reduces seawater generation vibrates the impact on extra large cable, described the first sleeve pipe adopts metal material to make, described the 3rd rigid casing pipe or flexible pipe.
Described the second sleeve pipe is corrugated flexible metal tube.
The elastic tube that described the second sleeve pipe also can adopt rubber and flexible steel ring combination to make.
The elastic tube that described the second sleeve pipe can also adopt polyurethane to make.
The extra large cable protection sleeve pipe of a kind of offshore wind generating of the utility model; sea cable is through the first sleeve pipe, the second sleeve pipe and the 3rd sleeve pipe that connect successively; the first sleeve pipe adopts rigid pipe to be fixedly connected with wind-driven generator bracing frame; the second sleeve pipe adopts flexible pipe; the appearance of the second sleeve pipe is accordion ringwise; can avoid extra large cable excessive and impaired because bending, the vortex street that simultaneously reduces seawater generation vibrates the impact on extra large cable.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail, wherein:
Fig. 1 is the extra large cable protection sleeve pipe schematic diagram of offshore wind generating.
Fig. 2 is extra large cable protection sleeve pipe wind-driven generator bracing frame use at sea schematic diagram.
[embodiment]
Below in conjunction with accompanying drawing, execution mode of the present utility model is elaborated.
The extra large cable protection sleeve pipe of a kind of offshore wind generating of the utility model; comprise the first sleeve pipe 1 being fixedly connected on wind-driven generator bracing frame 4; described the first sleeve pipe 1 lower end is connected with the second sleeve pipe 2; described second sleeve pipe 2 another free ends are connected with the 3rd sleeve pipe 3; described the first sleeve pipe 1 is rigid pipe, and described the second sleeve pipe 2 is flexible pipe.Sea cable adopts rigid pipe to be fixedly connected with to facilitate through the first sleeve pipe 1, the second sleeve pipe 2 and the 3rd sleeve pipe 3, the first sleeve pipes 1 successively; The second sleeve pipe 2 adopts flexible pipe, and the appearance of the second sleeve pipe 2 is accordion ringwise, when seawater scouring, can produce elasticity bending, avoids inner extra large cable to damage because bending excessively.
Described the first sleeve pipe 1 is fixedly connected with by flange 11 with wind-driven generator bracing frame 4, and described the first sleeve pipe 1 adopts metal material to make, described the 3rd sleeve pipe 3 rigid pipes or flexible pipe.
In the utility model, described the second sleeve pipe 2 can adopt corrugated flexible metal tube, and the elasticity that corrugated flexible metal tube tool is good has resistance to resistance to compression and corrosion resistant feature simultaneously.
The elastic tube that the second sleeve pipe 2 described in the utility model also can adopt rubber and flexible steel ring combination to make, or the elastic tube that adopts polyurethane to make.
