Embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows, see also Fig. 1-Fig. 5.

As shown in Figure 1: fairlead cage comprises heavy fairlead cage 1, light-duty fairlead cage 2, haulage cable 3 and bury cable machine 4, as Fig. 2, shown in Figure 3: the A cage body 6 that heavy fairlead cage 1 usefulness articulated slab 5 is hinged constitutes, each cage body 6 is divided into two halves, one end of two halves is hinged, the other end has A wire rope hole 7, penetrate haulage cable 3 in the wire rope hole 7, two halves constitute circular cavity altogether, and pin with A pin 9, place cable 8 in the circular cavity, heavy fairlead cage 1 is connected and buries on the cable machine 4, because of the A cage body 6 on the heavy fairlead cage 1 is connected through the hinge each other, can in certain angle, rotate, can prevent that the minimum bending radius of radius of turn less than cable 8 from appearring in cable 8 when going into to bury cable machine 4, and make cable 8 internal structures impaired, also can protect cable 8 to follow simultaneously and make cable failure when friction takes place some barriers on the sea bed; As Fig. 4; shown in Figure 5: light-duty fairlead cage 2 comprises B cage body 10; extension bar 11; steel loop 12 and steel rod 13; each B cage body 10 is made up of three steel loops 12; on on three steel loops 12; following two steel loops are identical; middle steel loop is not with wire rope hole 15; three steel loop 12 usefulness steel rods 13 fuse; B cage body 10 in two; but the hinged folding of an end; cable 8 can be placed in the centre of B cage body 10; after closing; fixedly connected with B pin 14; the both sides of B cage body 10 all have B wire rope hole 15 can wear haulage cable 3; for each B cage body 10 of weight reduction segment distance of being separated by links into an integrated entity with extension bar 11; promptly when the deepwater regions cabling in order to alleviate the overall weight of fairlead cage; remainder adopts light-duty fairlead cage 2 when using heavy fairlead cage 1, not only can protect cable 8 but also can play good guide effect in the seabed trend by cable 8.The fairlead cage entire length can increase and reduce according to the depth of water, and the dismounting convenient transportation can splice fast between the B cage body 10 on 11 pairs of light-duty fairlead cages 2 of extension bar, and form an integral body, the effect of playing cable 8 guiding and preventing to twist together; A pin 9 and B pin 14 can make the site operation personnel fast heavy fairlead cage 1 and light-duty fairlead cage 2 be carried out folding, and easy disassembly has reduced the fairlead cage dismounting time, have improved cable 8 laying speed.Cable 8 also can effectively reduce the contact with extraneous barrier under the protection of fairlead cage simultaneously, greatly reduces the influence of external object to cable 8.

During use, begin to bury cable machine 4 on hull 17 decks, earlier with the joint of one on the heavy fairlead cage 1 A cage body 6 with bury cable machine 4 and be connected, it is locked that cable 8 is put into A cage body 6, steel wire rope on the card, slowly put down the cable machine 4 that buries again, the limit is put down and is buried cable machine 4 limits and connect a plurality of A cage bodies 6 successively, and it is locked that meanwhile cable 8 is put into A cage body 6, then, the light-duty fairlead cage 2 of a section connection, heavy fairlead cage 1 and light-duty fairlead cage 2 connect to one, bury cable machine 4 and are being with cable 8 and haulage cable 3 to fall into sea bed 16, and the other end of haulage cable 3 is on hull 17 decks, moving down of hull 17, cable 8 imbed sea bed 16 below.

Its advantage is: heavy fairlead cage 1 and light-duty fairlead cage 2 are the single-unit parts; be respectively hinged; the dismounting convenient transportation; and can splice fast, reduce the fairlead cage dismounting time, improve cable 8 laying speed; make fairlead cage form an integral body; the effect of playing cable 8 guiding and preventing to twist together, cable 8 also can effectively reduce the contact with extraneous barrier under the protection of fairlead cage simultaneously, greatly reduces the influence of external object to cable 8.

Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection range of the utility model claims.
