Description
Technical Field
The utility model relates to a novel plugging device for hull hole, hole.
Background
Offshore floating facilities (including FPSO, FPS, FSOU and the like) are central facilities for offshore oil field production, are main production devices for offshore oil and gas field development, integrate production command systems for crude oil and natural gas primary processing, storage and the like, have the design life of more than 30 years, and generally require docking every decade for dock repair. And the dock repair project comprises the operations of dismantling and inspecting the sea valve and testing the pressure. However, the docking and dock repair needs to perform operations of single-point release, towing and dock repair, expensive resources such as air diving, saturated diving, large engineering ships and docks are used, and the docking and dock repair cycle is long, which causes long-term production stoppage of the oil field.
A plurality of air holes and sand discharge holes are formed in a hull of the offshore floating facility, and in the repair or replacement process, the air holes and the sand discharge holes need to be plugged, so that the plugging requirement is that water is not leaked, and the requirement can be met. However, these holes are characterized in that there is no construction space inside the holes, and therefore, it is a difficult problem how to successfully plug the air holes and the sand discharge holes. Patent application number is 200920039083. X's patent document discloses a floating dock submarine gate is shutoff watertight device under water, including the dock body, grid, watertight door closure and hook screw subassembly, the watertight door closure sets up in the dock body submarine gate outside, and the inboard edge of watertight door closure is inlayed rubber packing, and the inboard edge of this rubber packing outer fringe protrusion watertight door closure, hook screw subassembly includes hook screw, sealing washer, interior taper pad and nut, hook screw stretches into along the grid space in following the hole of watertight door closure terminal surface to cross 90 and hook the grid spoke, hook screw afterbody is adorned the sealing washer in proper order, is sheathe in interior taper pad and is screwed up the nut and screw up.
According to the technical scheme, the submarine gate of the dock body can be tightly plugged due to the adoption of the hook screws. However, the method is not suitable for the situation of blocking the air holes and the sand discharge holes in the scheme.
SUMMERY OF THE UTILITY MODEL
The invention aims to provide a novel plugging device which is convenient to install and disassemble and used for holes and holes of a ship body.
The technical scheme of the utility model as follows: a plugging device for holes and cavities of a ship body comprises: the screw rod is used for penetrating through holes and holes to be blocked; a locking element for locking the occlusion device; the screw rod is characterized in that one end of the screw rod is fixedly connected with two parallel connecting rods, and a connecting hole is formed in the same position of the two parallel connecting rods; the movable baffle is arranged between the two parallel connecting rods and is connected with the two parallel connecting rods through the connecting holes, and the movable baffle can freely rotate in a gap between the two parallel connecting rods by taking the connecting holes as a circle center.
Further, the plugging device comprises sealing rubber which is used for being installed on the screw rod to enhance the sealing effect.
Further, the plugging device comprises a sealing gasket which is used for being installed on the screw rod to enhance the sealing effect.
Preferably, the locking element is a nut.
The utility model discloses an useful part lies in, proves through the actual operation, adopts bleeder vent and the sediment outflow hole on the hull of this plugging device shutoff marine floating facility, and the shutoff construction is simple, and the shutoff is effectual, and the reliability is high.
Drawings
Fig. 1 is a front view of the plugging device of the present invention;
fig. 2 is a top view of the plugging device of the present invention.

Detailed Description
The invention will be further explained with reference to the drawings and examples, as shown in fig. 1, 2 and 3:
a plugging device for holes and cavities of a ship body comprises: the screw rod 1 is used for penetrating through holes and holes needing to be plugged on the ship body plate 8; a locking element 7 for locking the occlusion device; one end of the screw rod 1 is fixedly connected with two parallel connecting rods 4, and a connecting hole 6 is formed in the same position of the two parallel connecting rods 4; the movable baffle 5 is arranged between the two parallel connecting rods and is connected with the two parallel connecting rods 4 through the connecting hole 6, and the movable baffle can freely rotate in a gap between the two parallel connecting rods 4 by taking the connecting hole 6 as a circle center.
Further, the plugging device comprises a sealing rubber 3 which is used for being arranged on the screw rod 1 to enhance the sealing effect.
Further, the plugging device comprises a sealing gasket 2 which is used for being arranged on the screw rod 1 to enhance the sealing effect.
Preferably, the locking element is a nut 7.
The utility model discloses a use method does: after cleaning up marine organisms in the ventilation holes and around the ventilation holes, a diver keeps the movable baffle plate and the screw rod at 180 degrees before installation. The movable baffle is plugged into the ventilation hole, and the movable baffle is changed into a vertical state downwards under the action of gravity; the plugging device is tensioned, the movable baffle plate is similar to a barb and can hook the inner wall of the hole, so that the plugging device and the end face of the ship plate form a sealing surface, then a diver installs the sealing gasket 2 and the sealing rubber 3 and screws up the locking element to complete plugging.
The present invention has been described in detail with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above embodiments, and various insubstantial improvements can be made without modification to the present invention.
