Detailed description of the invention
Embodiment of the present utility model proposes a kind of boats and ships opening cover plate under water, for being sealed in boats and ships opening under water, so that insulating sea water.After the opening under water of boats and ships is sealed, boats and ships just can keep in repair in the situation that not entering dock.Boats and ships under water opening include but not limited to, boats and ships thruster cylinder two ends port, boats and ships sea chest and boats and ships outboard hole.Corresponding maintenance comprises removing of thruster maintenance, subsea pump maintenance and mud shellfish etc.
Fig. 1 illustrates the boats and ships opening cover plate front view under water of the utility model one embodiment.Fig. 2 illustrates the boats and ships opening cover plate lateral plan under water of the utility model one embodiment.Fig. 3 illustrates the boats and ships local edge view of opening cover plate under water of the utility model one embodiment.Shown in figure 1-3, boats and ships under water opening comprise plate body 11 and seal ring 12 with cover plate 10.The shape of the opening under water that plate body 11 is corresponding with boats and ships with the shape of hull contact portion matches.In the present embodiment, opening is the both sides port of boats and ships thruster cylinder under water.Correspondingly, in the present embodiment, the shape of plate body 11 is set to polygon, for example octagon.Plate body 11 is curved surface slightly.Seal ring 12 is arranged on plate body 11.Particularly, seal ring 12 is located at plate body 11 on sealing surface (inside face).On plate body 11, also there is the first connection structure, for the corresponding oral area of thruster cylinder on the second connection structure coordinate, cover plate is installed to the corresponding oral area of thruster cylinder.In the present embodiment, the first connection structure comprises multiple screw rods 20.One end of each screw rod 20 is arranged in the perforation of plate body 11 by nut 21.The other end of each screw rod 20 has hook portion 22 so that and the second connection structure cooperation.In the present embodiment, the second connection structure is the grid in the both sides port of thruster cylinder.
Plate body 11 can be double layer sandwich structure, comprise exterior skin, inside panel and be wrapped in this exterior skin and this inside panel between core.
Preferably, the proportion of cover plate 10 is about 1g/cm
3.This proportion and sea water density are suitable, can allow cover plate 10 substantially can be suspended under water, are convenient to Divers and operate under water cover plate and install.In order to obtain lighter density, the material of plate body 11 can be glass-felt plastic, such as poly-ester fibres or resin fibre etc.
Owing to will bearing certain sea pressure, cover plate 10 has certain requirement of strength.For instance, if require cover plate 10 can bear 15 meters of pressure under water, can set cover plate 10 15 meters of under water, maximum displacement is 5.2mm, and maximum Mises' (Mises) stress value is 47MPa.Cover plate 10 can calculate through finite element method, to meet requirement of strength.In order to improve intensity, can be at the interior reinforced rib that arranges of plate body 11.
Fig. 4 illustrates boats and ships angular views of opening cover plate under water of another embodiment of the utility model.Fig. 5 illustrates boats and ships another angular views of opening cover plate under water of another embodiment of the utility model.Fig. 6 illustrates the boats and ships local edge view of opening cover plate under water of another embodiment of the utility model.Shown in figure 4-6, boats and ships under water opening comprise plate body 31 and seal ring 32 with cover plate 30.The shape of the opening under water that plate body 31 is corresponding with boats and ships with the shape of hull contact portion matches.In the present embodiment, opening is boats and ships sea chest under water.Correspondingly, in the present embodiment, the shape of plate body 31 is set to polygon, for example rectangle.Plate body 31 is plane.Seal ring 32 is arranged on plate body 31.Particularly, seal ring 32 is located at plate body 31 on sealing surface (inside face).On plate body 31, also there is the first connection structure, for sea chest on second connection structure coordinate, so that cover plate is installed on sea chest.In the present embodiment, the first connection structure can comprise multiple bolts.In the screw 41 of the each ear 40 that is arranged on plate body 31 of each bolt.Second connection structure (nut) of each bolt and sea chest coordinates.In another embodiment, the first connection structure can comprise multiple screw rods.One end of each screw rod is arranged in the perforation of plate body 31 by screw thread.The other end of each screw rod has hook portion so that and the second connection structure cooperation.The second connection structure of sea chest is the grid on doorway, seabed.
Plate body 31 can be double layer sandwich structure, comprise exterior skin, inside panel and be wrapped in this exterior skin and this inside panel between core.
Preferably, the proportion of cover plate 30 is about 1g/cm
3.This proportion and sea water density are suitable, can allow cover plate 30 substantially can be suspended under water, are convenient to Divers and operate under water cover plate and install.In order to obtain lighter density, the material of plate body 31 can be glass-felt plastic, such as poly-ester fibres or resin fibre etc.
Owing to will bearing certain sea pressure, cover plate 30 has certain requirement of strength.For instance, if require cover plate 30 can bear 15 meters of pressure under water, can set cover plate 30 15 meters of under water, maximum displacement is 5.2mm, and maximum Mises' (Mises) stress value is 47MPa.Cover plate 20 can calculate through finite element method, to meet requirement of strength.In order to improve intensity, can be at the interior reinforced rib that arranges of plate body 31.
In each embodiment, cover plate the 10, the 30th, matches with the corresponding opening shape of boats and ships.For instance, boats and ships thruster is equipped with cover plate 10.Before installation, first two braids are tied down to cover plate 10, use crane to hang two braids, cover plate 10 is mentioned near the seawater slowly putting into.Diver buttresses buoyancy cover plate 10 in water, coordinates crane to be moved to the oral area of thruster cylinder.Diver dives beneath the water, and fastening all screw rods are until cover plate for sealing circle and hull are identical.Once thruster cylinder internal pressure reduces, outside sea pressure can be tighter cover plate being sealed on hull.The operation of another piece cover plate is identical with first.After the buoyancy cover plate of boats and ships both sides is all in place, the water in thruster cylindrical shell is all extracted out with inner lift pump and drainage system.Diver does safety inspection in buoyancy cover plate, after all are normal repairmans can approaching side ejector sleeve in the work that places under repair.The installation process of the cover plate 30 of sea chest is similar.
Therefore by the setting of cover plate, the maintenance of equipment work in boats and ships thruster cylinder, sea chest, outboard hole needn't be arrived in dock and be carried out, saved thus 60% lie up maintenance cost and save 70% navigation maintenance time.Because ships quantity is huge, this technical scheme can be saved every year several hundred million costs for whole maritime industry.
Although the utility model discloses as above with preferred embodiment; so it is not in order to limit the utility model; any those skilled in the art; not departing from spirit and scope of the present utility model; when doing a little amendment and perfect, therefore protection domain of the present utility model is worked as with being as the criterion that claims were defined.
