The load of degree, therefore can maintain the original state, gravity anchor 7 and anchor chain storage box 1 provide necessary anchor as string anchor structure in seabed
Gu power.
When deep ocean buoy installs seabed anchoring system, the use step of releasable formula gravity anchor system is as follows：
The first step：Buoy hangs lower water
The buoy 16 connected with hoist steel cable is slowly lifted to the water surface using the folding arm loop wheel machine of operation ship, pays attention to keeping
The posture of buoy 16, while pay attention to avoiding buoy 16 from colliding ship.
Second step：The dispensing of end anchor chain and plastic wirerope
Fender is installed on the outside of operation ship, buoy 16 is pulled to operation ship front middle part, the situation of conditions permit with hawser
Under can utilize small watercraft assist operation, after buoy 16 is dragged to designated position, hawser is tensed.
The end anchor chain 17 on buoy 16 is dragged on operation ship using windlass capstan winch and is connected with plastic wirerope 15, then uses anchor
Machine capstan winch launches plastic wirerope 15 into water.
3rd step：The dispensing of nylon cable and polypropylene cable
When the plastic dispensing of wirerope 15 is nearly completed, using the ship upper end of only knot fixed packet plastic-steel cable 15, by plastic wirerope
15 dock with nylon cable 14, and nylon cable 14, polypropylene cable 12, floating ball 13 etc. slowly descend water by capstan winch, finally by polypropylene cable
12 one end are fixed in the bollard of operation ship.
4th step：The dispensing of gravity anchor, anchor chain storage box and anchor end connection chain link
After the completion of the dispensing of polypropylene cable 12, dan anchor end anchor chain is hung on the outside of operation ship section by section, while utilize loop wheel machine
Gravity anchor 7, anchor chain storage box 1 are hung on the outside of operation ship, all fixed with cable wire.Confirm gravity anchor 7 and anchor chain storage box 1 it
Between, the connection anchor chain of the outside of anchor chain storage box 1 and quick coupling etc. connect it is appropriate, by shackle sealing lead, then by all anchor pasterns
Part is lifted to operation ship.Transition anchor chain is connected with polypropylene cable 12, and linkage section is put on the outside of operation ship, with wirerope by the end
Head is fixed in operation ship bollard.Operation ship is started, to erect-position traveling is laid, after arriving at erect-position, by fixed gravity anchor 7 and anchor
The cable wire of chain storage box 1 disconnects, and gravity anchor 7 and anchor chain storage box 1 enter water at the same time, at the same also drive anchor end anchor chain it is piecewise under
Water.When the actual depth of water is more than design head, 1 inside Bower Anchor chain 801 of anchor chain storage box will discharge so that gravity anchor 7 arrives at sea
Bottom.So far, the dispensing work of buoy 16 is completed.
Although the function and the course of work of the utility model are described above in conjunction with attached drawing, the utility model is simultaneously
Above-mentioned concrete function and the course of work are not limited to, above-mentioned embodiment is only schematical, rather than limitation
Property, those of ordinary skill in the art, will not departing from the utility model aims and right under the enlightenment of the utility model
Ask under protected ambit, many forms can also be made, these are belonged within the protection of the utility model.
