Abstract
The utility model discloses an offshore wind-power conduit support base submarine cable laying protection apparatus including a first protection sleeve, a second protection sleeve and a third protection sleeve. The third protection sleeve sleeves one end of a submarine cable. The second protection sleeve is formed by assembling multiple small components which are fastened together by bolts. Both the first protection sleeve and the second protection sleeve are fixed on a wind turbine generator conduit support. The other end of the submarine cable, from the bottom end of the second protection sleeve, sequentially penetrates through the second protection sleeve and the first protection sleeve to be connected with a tower bottom transformer in the offshore wind turbine generator. The offshore wind-power conduit support base submarine cable laying protection apparatus solves a problem of laying submarine cables at the base of a draught fan conduit support of an offshore and intertidal zone wind plant, and helps to shorten the construction period, simplify the construction process, substantially reduce the construction cost, and optimize the submarine cable laying process.

Utility model content
The purpose of this utility model is to provide the extra large cable in place, a kind of coastal waters, intertidal belt submarine windward conductivity cell frame basis and lays protective device, the problem of laying to solve coastal waters, marine site, intertidal zone wind turbine group sea cable.
For achieving the above object, the utility model provides following technical scheme:
The extra large cable in place, offshore wind farm jacket basis lays protective device, comprises the first protective casing, the second protective casing and the 3rd protective casing; Described the 3rd protective casing is sleeved on one end of extra large cable; Described the second protective casing is assembled by bolted widgets together by a plurality of; Described the first protective casing and the second protective casing are all fixed on wind-powered electricity generation unit jacket basis; The other end of described extra large cable from the bottom of second guarantor's sleeve pipe successively through transformer at the bottom of the tower in the second protective casing and the first protective casing access offshore wind farm unit.
Further, the length of described widgets is 248～380mm, and the bending radius of extra large cable is limited, and guarantees that extra large cable actual flexion radius is greater than the minimum bending radius of its permission.
Further, described the first protective casing and the second protective casing assemble by the widgets together with bolted by a plurality of.
The utility model is compared with conventional art, has the following advantages:
The utility model has solved the problem that coastal waters, the extra large cable in intertidal zone marine wind electric field fan jacket basis lay, and has shortened the construction period, has simplified working procedure, greatly reduces construction cost, has optimized extra large cable and has laid technique.

Fig. 1 is the utility model scheme of installation;
Fig. 2 is the structural representation of the second protective casing described in the utility model.
In figure, the structure of digital representative is respectively: 1-the first protective casing; 2-the second protective casing, 3-the 3rd protective casing, 4-fixed connection apparatus; 5-tie point (each widgets link position in protective casing); 6-leads and turns round frame, 7-workboat, 8-suspension hook; 9-sea cable; 10-sea level, 11-sea bed, 12-widgets
Embodiment
Below in conjunction with the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1-2, the extra large cable in place, offshore wind farm jacket basis lays protective device, comprises the first protective casing 1, the second protective casing 2 and the 3rd protective casing 3; Described the 3rd protective casing 3 is sleeved on one end of extra large cable 9; Described the second protective casing 2 is assembled by bolted widgets 12 together by a plurality of; Described the first protective casing 1 and the second protective casing 2 are all fixed on wind-powered electricity generation unit jacket basis; The other end of described extra large cable 9 from the bottom of second guarantor's sleeve pipe 2 successively through transformer at the bottom of the tower in the second protective casing 2 and the first protective casing 1 access offshore wind farm unit.
Wherein, the length of the widgets of composition the second protective casing 2 all, between 248～380mm, limits the bending radius of extra large cable, guarantees that extra large cable actual flexion radius is greater than the minimum bending radius of its permission; The first protective casing 1 and the second protective casing 2 can adopt a plurality of widgets assemblings, or other modes.
Concrete installation process is as follows: the first protective casing 1 and the second protective casing 2 are fixed on wind-powered electricity generation unit jacket basis by fixed connection apparatus 4 in advance, first the 3rd protective casing 3 covers are filled on extra large cable 9 to be laid on the coast, and reserve the not protection section of being a bit larger tham the first protective casing 1 and the second protective casing 2 overall lengths in extra large cable terminal; After the 3rd protective casing 3 installations, by workboat 7, to harbour, there is the extra large cable 9 of the 3rd protective casing 3 to load and transport in cover, utilize hawser traction construction ship 7 near wind-powered electricity generation unit terminal, device leading on workboat 7 turned round to frame 6 and put into water, start and be contained in the hanging apparatus on workboat 7, to be suspended on haulage cable on suspension hook 8 from draw the upper end of the first protective casing 1, from the end of the second protective casing 2, draw, and the steel wire rope of drawing the second protective casing 2 is loaded onto to wire sets be connected with extra large cable end; The first protective casing 1 and the second protective casing 2 substitute J type pipe of the prior art; Complete being connected and fixed rear loop wheel machine and starting hanger rope, it is inner and access transformer at the bottom of tower that the most extra large cable causes offshore wind farm unit.
To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the situation that not deviating from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than above-mentioned explanation, is therefore intended to include in the utility model dropping on the implication that is equal to important document of claim and all changes in scope.
In addition, be to be understood that, although this specification is described according to execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should make specification as a whole, and the technical scheme in each embodiment also can, through appropriately combined, form other execution modes that it will be appreciated by those skilled in the art that.
