Abstract

The invention relates to a combined floating anchor shaped in a starfish using five claws to grap the sea bottom. Surrounding a central cylinder 1 tied by an anchor line 7, five pairs (or more) of lag-clawing plates 2 are welded, in the crack of which a long craw 3 is arranged which can swing up and down along a spool 22. The external shoot end of 3 is like a dozer bucket of a super huge bulldozer and can tackle in the soil layer at the sea bottom. The extended part of each pair of lag-clawing plate 2 has a cam wheel 24. Under the weight force of the bucket 25 which packs big block of olivine(big density), the cam 24 resists a pod block 30 in a clockwise way. The lower claw 3 is pressed for swinging along the spool 23 until the clapped soil layer into the sea bottom is fastened. Each pair of claws corresponding to the long claw 3 forms an arched force with a big span. Each weight force of the cam and the big block bucket are concentrated on each claw part, therefore, the claws are stable. Particularly, the claw 3 is suitable to the disaffection sea bottom and supports and fixes the central cylinder of the anchor line.

Description of drawings

Fig. 1 is the lateral plan of combination type floating raft anchor of the present invention.

The specific embodiment

Among Fig. 1, central tube 1 periphery is welded with uniform some two (from 5 pairs to more two) pawl leg plates 2, and assembly can free movable pawl 3 in spacing in every pair of pawl leg plate 2, and the outer end of pawl 3 is as the bucket that pushes away of huge bulldozer---and nationality is gone into the seabed and pawl jail anchoring with shovel; The every pair of pawl leg plate 2 is with central tube 1 and go up plate 4, lower disk board 5 solid weldings, overhanging position with lower cross plate 20, down stretch transverse slat 21 welderings join every pair of pawl leg plate 2 about two standard width of a room in an old-style house distances, the suitable for reading of standard width of a room in an old-style house distance connects firmly with

axle

22 and 23; But axle 22 is running-fits with the hole of pawl 3; The hole running-fit of axle 23 and cam 24.The sponson of cam 24 is installed with composite material (as the synthetic glass fiber) bucket 25 (the big boulder of interior dress density, for example olivines) of metal frame with bolt.

If a certain pawl 3 is uneven when unsettled because of the seabed, it is that the axle center clockwise rotates with axle 23 that the weight of its bucket 25 is impelled cam 24, push against cushion block 30 (the diagonal orientation finger setting of available cushion block, increase and decrease piece number) depress pawl 3 with axle 22 be the axle center down change until penetrate the seabed firm till.Hence one can see that, the capsizing moment of central tube 1 under the effect of anchor cable (material such as glass fibre syntheticfibres) 7, is supported on the pawl 3 that penetrates mud layer by the wedge action of 24 pairs of cushion blocks 30 of cam.

Involutory annulus 6 (left side among the figure) is fastening with king bolt, opposite side is clipped in two outerplanars of 6 and passes through quadripuntal with spools 61 with clasp 60, fixed by nut, make 1 movable cooperation of involutory annulus 6 and central tube, clasp 60 can freely swing on axle 61, and the cringle of anchor cable 7 is entangled at the semi-circular cross-section place, outer end of clasp 60.

The big pad 40 of involutory annulus 6 underlay plastics, on serve as a contrast the big pad 41 of plastics (tightly staying in the following of vexed plate 11) with screw.Circular vexed plate 11 solid weldings are on central tube 1, run through, weld a firmly vertical tube 13 at vexed plate 11 centre holes, upper orifice at vertical tube 13 welds a flange 14, run through vertical tube 13 with the centre hole (shown in the dotted line) of the blue dish 14 of vertical part insertion of bend pipe 15 after, R connects with the flexible axle pipe.Flexible axle pipe R is very long, a medium-soft thick-walled pipe (as being lined with reticulate pattern line-can bear than high pulling torque in very resistant to bending polypropylene pipe, the wall layers), the major part of R is through among the metal conduit S, and conduit S is clamped in putting on the bar and be contained in the buckle of transverse slat 20 in the central tube 1.

Input cable 8 penetrates among bend pipe 15, vertical tube 13, the flexible axle pipe R, and (with R together) passes after the conduit S mouth of pipe of bending, pass the aperture of sealing shroud of the anti-silt of soft elasticity again after, cable just be can be regarded as the output cable 9 of anchor.Soft elastic seal cartridge is a tubular shape, the hole fastening of big end, is fixed on outside the outlet caliber of conduit S, and flexible axle pipe R stretches out behind the conduit S mouth of pipe also in the vestibule of the big end of sealing shroud; Cable passes the small end egress hole that just passes sealing shroud behind the R pipe, just becomes the output cable 9 of anchor.

The right side of the flange 16 of the horizontal arrangement of bend pipe 15 be welded with the curved driving lever of an angle square insert clasp 60, shape is like in the crack of n shape, makes bend pipe 15 and anchor cable 7 synchronous in the time of central tube 1.The left side of flange 16 is welded with a little hook (L shaped), is flange 16 and flange 14 can only be turned round by coaxial line, can not separate.

Input is before cable 8 enters bend pipe 15, be loosely, branch system hangs on the anchor cable.Ball float 80 usefulness tethers 81 hang on the input cable 8, when purpose prevents that anchor cable contingency is loose, sink to putting on the spot following anchor body.

Output cable 9: the transmission that is in line basically, and carry transverse tube folder 91, hitch the boulder mesh bag with restricting and be positioned at the seabed with a plurality of ball floats 90 (diagram only draw); Transverse tube folder 91 is a kind of plastic pipes that crack, and breaks the slit into two with one's hands and puts into cable in pore, with screws clamp and clamp downside at ball float 90 simultaneously.Cable 9 turns very loosely in transverse tube folder 91 or string moves, plastics seem that in water friction coefficient is especially little, cable floats over and seems lighter in the water, the protective layer of external cylindrical surface is smooth and certain well-pressed degree arranged, so can be in the horizontal direction, rectilinear wearing hang in a plurality of transverse tubes folders 91, buoyancy is arranged in water, and friction coefficient is little, all favourable make cable be driven, lentamente around its rotational.

In other words: anchor cable 7 is hitched, understands around the central tube 1 of anchor because of the wind direction conversion and rotate half-turn by floating Bamboo-raft, bend pipe 15 that changes synchronously with its (in the input cable is arranged) also can rotate, and therefore just driving flexible axle pipe R also changes synchronously, also must change half-turn through the cable 9 of conduit S output; Deliver to when closing on the destination when cable 9, be raised to obliquely gradually and leave sea level line, by current colector to the electricity consumption place.

The current colector of connection seabed output cable 9 seldom rotates and changes very slowly, generally only changes half-turn, just in case there is jumper spark to take place can carry out in the capacitor oil of like big voltage transformer always.Set up cable by the seabed suspended pattern and (please consult " ocean bottom large cable construction " of recent application, application number: 200710156134.2).
