Description
Technical field
This utility model relates to the curved protection pipe of a kind of offshore wind turbine cable limit.Suitable in offshore wind farm field of engineering technology.
Background technology
At present, near blower fan seat in the plane during Submarine Cable Laying, require to throw between sea plough and platform and there is certain safe distance, be generally adopted first lay, mode that backlash is buried carries out operation, but the J type cable protecting tube that marine wind electric field is conventional cannot directly go deep under mud, be connected to the cable on blower foundation have near mud face one section unsettled；On the other hand, in cable During Process of Long-term Operation, cable tube position is washed away relatively big, and mud face changes, and turning of cable radius cannot ensure, wave, ocean current long term under, J type pipe exit turning of cable radius cannot ensure there is the potential safety hazards such as fracture distress.
Existing general cable bend limiter price is high, and needs to arrange cable center's fixture, and cable center's fixture must be inserted in J type pipe by underwater operation by diver, and underwater operation difficulty is bigger.
Summary of the invention
The technical problems to be solved in the utility model is: for above-mentioned Problems existing; there is provided a kind of offshore wind turbine cable limit curved protection pipe; it is intended to the sweep bottom protection I type or J type cable protecting tube; part bend pipe is made to be embedded in below mud face; ensure turning of cable radius, it is prevented that cable exposes and fracture distress.
The curved protection pipe of this utility model the technical scheme is that offshore wind turbine cable limit; there is the single-pile foundation of offshore wind turbine; this single-pile foundation outer wall installs the cable protecting tube vertically arranged by the cable support pipe of level; submarine cable it is installed with in cable protecting tube; it is characterized in that: the bottom of described cable protecting tube connects cable limit bend pipe by transition Taper Pipe, and described cable limit bend pipe has part body to be embedded in below sea bed mud face；Described submarine cable limits the end of bend pipe to enter, be connected with the high-voltage ring main unit within the blower fan tower barrel being arranged on single-pile foundation top after transition Taper Pipe and cable protecting tube from cable.
Described cable protecting tube has some, by cable connecting rod lateral connection between adjacent cable pillar.
Described cable protecting tube includes I type cable protecting tube or J type cable protecting tube.
Described cable limit bend pipe is formed by multiple seamless steel pipe unit spliceds, and each seamless steel pipe unit length 0.5～1m, the port at two ends is circumferentially shaped with the double wedge of mushroom-shaped uniformly, and adjacent two seamless steel pipe unit are engaged by described double wedge.
The beneficial effects of the utility model are: this utility model adopts cable limit bend pipe to be connected with top I type or J type cable protecting tube by transition Taper Pipe, solve wave, ocean current long term under the damaged difficult problem of the turning easy fracture of cable protecting tube, guarantee turning of cable radius, it is prevented that the potential safety hazards such as the fracture of sea, cable protecting tube exit cable, breakage occur.

Detailed description of the invention
As shown in Figure 1; the present embodiment offshore wind turbine cable limits curved protection pipe to be arranged on the side of offshore wind turbine single-pile foundation 10; this example passes through the cable protecting tube 1 of the vertically-mounted two J types (may also be I type) of cable support pipe 2 of level at single-pile foundation 10 outer wall, and cable protecting tube is used for protecting submarine cable 6 from damage.Innovation of the present utility model is in that to limit bend pipe 5 to connect in the bottom of the cable protecting tube 1 being subject to ocean current, wave cut most with one section of cable, end 2～the 3m of described cable limit bend pipe 5 is embedded in below sea bed mud face, and the other end is connected with cable protecting tube 1 lower end by transition Taper Pipe 4.Described submarine cable 6 limits the end of bend pipe 5 to enter, be connected with the high-voltage ring main unit within the blower fan tower barrel being arranged on single-pile foundation 10 top after transition Taper Pipe 4 and cable protecting tube 1 from cable
The cable protecting tube 1 of this example has 2, by cable connecting rod 3 lateral connection between two cable protecting tubes.
Described cable limit bend pipe 5 is spliced by multiple seamless steel pipe unit 5-1, each seamless steel pipe unit 5-1 length 0.5～1m, the double wedge 5-1-1 of the port at two ends circumferentially cutting uniformly circle mushroom-shaped, the head of double wedge is diameter is the semicircle of 10～80mm, adjacent two seamless steel pipe unit are engaged by described double wedge, both sides semicircle handing-over occlusion position about 1/4 diameter length (junction reserves gap 5-1-2), the gap between circular arc and circular arc is 0～10mm.
The size of the present embodiment main member is as follows:
Described cable protecting tube 1 diameter is 200～400mm, wall thickness 14～20mm；Described cable support pipe 2 diameter is 200～400mm, wall thickness 14～20mm.
Described cable limit bend pipe 5 diameter is 400～800mm, overall length 5～20m, and end 2～3m is embedded in below mud face, seabed at least 2m.
During construction, adopt fish-wire that submarine cable 6 is limit bend pipe 5 end from cable, drawn to the blower fan tower barrel of top through transition Taper Pipe 4 and cable protecting tube 1, be connected with the high-voltage ring main unit of blower interior.
