A kind of plugging device outside Sea Chest, including：One locking mechanism, the plugging structure on locking mechanism, wherein, locking mechanism includes：Several set levers, several handle nuts, the tie down screw on handle nut that set lever side is arranged on using welding manner, wherein, locking nut is installed on tie down screw, the one end of tie down screw is provided with locking bail；Plugging structure includes：Sealing joint strip, the closure steel plate and floating material that are connected with sealing joint strip successively on tie down screw.The utility model at the scene can not only isolate hull with seawater, be realized under water by diver to pipe fitting replacing valve maintenance activity, solve the problems, such as that returning to dock after needing to free in whole floating type production, storage and offloading device places under repair；And, the efficiency of maintenance activity is substantially increased, reduce production cost.
Description
Technical field
The utility model is related to ship Sea Chest, more particularly to one kind to exist for floating type production, storage and offloading device (FPSO)
During offshore oilfield is runed, the plugging device outside Sea Chest for be easy to diver's replacing, maintenance, installing.Belong to ocean engineering
Construction applications.
Background technology
Floating type production, storage and offloading device (FPSO) is mooring in offshore oilfield, the treatment of collection crude oil production, storage it is outer defeated and
, in one of the offshore oilfield key facility of one, at sea oil field is on active service for a long time for it for life, power supply.At present, for floating
The repair and replacement of Sea Chest or cabin inside the pipe fitting valve of production storage and offloading device (FPSO), can only give birth to whole floating
Produce return dock after storage and offloading device (FPSO) is freed to place under repair, so, towage operation is not only needed, to needing more
The part for change, repairing places under repair in dock；And, the time-consuming more long, expense of operation for also resulting in repair and replacement increases.
Utility model content
Main purpose of the present utility model is the disadvantages mentioned above for overcoming prior art to exist, and provides a kind of seabed outdoors
The plugging device in portion, hull can not only be isolated, be realized under water to pipe fitting valve more by diver by it with seawater at the scene
Maintenance activity is changed, solves the problems, such as that returning to dock after needing to free in whole floating type production, storage and offloading device places under repair；
And, the efficiency of maintenance activity is substantially increased, reduce production cost.
The purpose of this utility model is realized by following technical scheme：
A kind of plugging device outside Sea Chest, it is characterised in that：Including：One locking mechanism, on locking mechanism
Plugging structure, wherein, locking mechanism includes：Several set levers, the number that set lever side is arranged on using welding manner
Individual handle nut, the tie down screw on handle nut, wherein, locking nut, tie down screw are installed on tie down screw
One end locking bail is installed；Plugging structure includes：On tie down screw sealing joint strip, be connected with sealing joint strip successively
Closure steel plate and floating material.
The side of the locking nut is provided with a lock washer, and sealing joint strip is arranged on the side of lock washer.
The beneficial effects of the utility model：, due to using above-mentioned technical proposal, it can not only be at the scene for the utility model
Hull is isolated with seawater, realizes that, to pipe fitting replacing valve maintenance activity, solving needs will entirely float under water by diver
Formula production storage and offloading device returns to the problem that dock places under repair after freeing；And, the efficiency of maintenance activity is substantially increased,
Reduce production cost.

Specific embodiment
As shown in Fig. 1-Fig. 3, the utility model includes：Locking mechanism 1, the plugging structure 2 on locking mechanism 1,
Wherein, locking mechanism 1 includes：Several set levers 1.1 (the present embodiment be two), set lever is arranged on using welding manner
Several handle nuts 1.2 (the present embodiment with set lever 1.1 correspond to two) of 1.1 sides, pacified using thread connecting mode
Tie down screw 1.3 on handle nut 1.2, wherein, locking nut 1.4, tie down screw are installed on tie down screw 1.3
1.3 one end is provided with locking bail 1.6；Plugging structure 2 includes：Mode is connected by screw bolts to be arranged on tie down screw 1.3
Sealing joint strip 2.1, it is connected by screw bolts closure steel plate 2.2 and floating material 2.3 that mode is connected with sealing joint strip 2.1 successively.
The side of above-mentioned locking nut 1.4 is provided with a lock washer 1.5, and sealing joint strip 2.1 is arranged on lock washer 1.5
Side.
During installation, the utility model is transported to the position of Sea Chest grid 3 of hull 4 by diver, then, by locking bail
1.6 through the gap of Sea Chest grid 3,1.1 to 90 ° of positions of rotational lock handle, and outwards drag set lever 1.1 so that
Locking bail 1.6 is locked spacing with Sea Chest grid 3.Diver tightens locking nut 1.4 again so that sealing joint strip 2.1 and seabed
The outer of door grid 3 is brought into close contact and forms extruding force so that plugging structure 2 forms sealing with the Sea Chest grid 3 of hull 4
Face, is finally reached plugging effect.It is opposite with above-mentioned installation process when the utility model is dismantled.
The above, is only preferred embodiment of the present utility model, not makees any formal to the utility model
Limitation, every any simple modification made to above example according to technical spirit of the present utility model, equivalent variations with
Modification, still falls within the range of technical solutions of the utility model.
