After the hatch cover plate is installed, the hatch cover plate can be in seamless shape with a deck plate at a corresponding position, is attractive and smooth, has simple process and reliable tightness, is made of conventional hull structural materials, has low cost, and is applied to the field of design and manufacture of ship outfitting.
Description
Technical Field
The invention relates to a watertight hatch cover for a ship, in particular to a cabin crane hatch cover for a ship, which has higher requirements on the flatness of a deck plate.
Background
Based on the dual requirements of shipbuilding and machine overhaul, the large-size crane port cover is quite common on small and medium-sized ships with the size below 60m, and has the characteristics of daily non-opening and detachable when needed. However, up to now, there are no unified national standard or industry standard, and if the standard is made with reference to the existing standard, there are two outstanding problems:
1. due to the fact that the weather-tight type hatch coaming is too high in protruding deck surfaces, and the crane opening is large in size, the weather-tight type hatch coaming is very in the way, the flatness of the deck is damaged, and the arrangement and the attractiveness of the deck are affected;
2. the adoption of the concave watertight type has the problems of large installation clearance, accumulated water in the concave part, exposed bolts, rough appearance, unattractive appearance and the like;
Therefore, it is necessary to design a special type of the crane mouth cover which is beautiful and reliable. Especially for middle and high-end ships, if the novel hatch cover type is adopted, not only the tightness completely meets the requirements of a class society, but also the deck arrangement can be improved, and the quality and the grade of the ship are obviously improved.
Disclosure of utility model
The technical problems to be solved by the invention are as follows: according to the characteristic of extremely low frequency of opening the crane mouth cover, take "tightness equivalent" and "level and beautiful" as starting points, design a kind of installation clearance is very little, the bolt is hidden, the deck is level and beautiful and the stealthy watertight crane mouth cover that the confidentiality is very high.
The technical scheme adopted by the invention is as follows: a invisible watertight crane cover comprises a cover plate (1), a sealing groove (6), a built-in fastening panel (7), an L-shaped seat ring (4), a fastening base (5) and a fastening bolt (9). The sealing groove (6) and the built-in fastening panel (7) are arranged on the inner side of the hatch cover plate (1), the L-shaped seat ring (4) and the fastening base (5) are welded on a structural strong frame around the hatch and are positioned below the hatch cover plate (1) to be at a certain depth, and the fastening bolts (9) are used for adjusting the distance between the built-in fastening panel (7) and the fastening base (5) on the lower side of the hatch cover plate (1) and the structural frame, so that the L-shaped seat ring (4) is extruded on the rubber sealing ring (8) in the groove below the hatch cover plate (1) to achieve the purposes of fastening and watertight.
Compared with the prior art, the utility model has the beneficial effects that: the deck after installation is smooth, the appearance is attractive, the process is simple, the tightness is reliable, the deck is made of conventional hull structural materials, the cost is low, and the deck is applied to the field of design and manufacture of ship outfitting. The cabin crane port is suitable for a cabin crane port which is extremely low in opening frequency and high in requirement on the flatness of a deck plate and needs to meet watertight requirements, and can be popularized and applied to other overhaul ports.

Detailed Description
As shown in fig. 1 to 3, the invisible watertight crane cover comprises a cover plate 1, a sealing groove 6, a built-in fastening panel 7, an L-shaped seat ring 4, a fastening base 5 and a fastening bolt 9. The sealing groove 6 and the built-in fastening panel 7 are arranged on the inner side of the hatch cover plate 1, the L-shaped seat ring 4 and the fastening base 5 are welded on a structural strong frame around the hatch and are positioned below the hatch cover plate 1 to be at a certain depth, and the fastening bolts 9 enable the L-shaped seat ring 4 to extrude the rubber sealing ring 8 in the groove below the hatch cover plate 1 by adjusting the distance between the built-in fastening panel 7 and the fastening base 5 on the structural frame below the hatch cover plate 1 so as to achieve the purposes of fastening and watertight.
The hatch cover plate 1 is in seamless joint with the deck plate 2 at the installation place, and the corner shape of the hatch cover plate 1 is parabolic or circular so as to reduce stress concentration.
After the hatch cover plate 1 is installed, the hatch cover plate can be in a seamless shape with the deck plate 2 at the corresponding position, and the deck surface is completely flat.
After the hatch cover plate 1 is installed, the tiny joint 3 is closed by sealant.
The hatch cover plate 1 is provided with a concave uncovering handle 10.
The fastening bolts 9 of the hatch cover plate 1 are completely concealed in the hatch and have no trace except for a very small seam 3 in appearance.
In practice, the hatch cover plate 1, the L-shaped seat ring 4 and the fastening base 5 must be made of a less flexible metallic material, such as steel or an aluminum alloy, to prevent deformation and leakage.
The hatch cover plate 1 is also provided with a reinforcing framework 11, the reinforcing framework 11 and the vertical structure of the fastening panel 7 are connected into a whole, and when the hatch cover plate 1 is used, the reinforcing framework 11 can ensure enough strength and rigidity.
In summary, the invisible watertight crane port cover provided by the utility model has the advantages of flat deck, attractive appearance, simple process and reliable tightness after installation, is manufactured by using conventional hull structural materials, has low cost, and is applied to the field of design and manufacture of ship outfitting. The method is suitable for the cabin crane port which is extremely low in opening frequency and high in deck flatness requirement and needs to meet watertight requirement, and can be popularized and applied to other overhaul ports.
