Disclosed in the present invention is a hull form of a shallow-draft anti-rolling transport vessel. The hull form comprises a stern section, a cargo hold section and a bow section which are connected in sequence, wherein the length of the stern section does not exceed 30% of the overall length of a vessel; the length of the bow section does not exceed 25% of the overall length of the vessel; the stern section uses a multi-hull structure; the cargo hold section uses a monohull structure; the bottom of the cargo hold section is of a double-bottom structure; the bow section uses a catamaran structure; side flare structures are arranged at both sides of the stern section and the bow section; the stern section, the cargo hold section and the bow section share a main deck; and the main deck is a flat grillage. In the present invention, by means of reducing the draft, a wetted surface area and a wave height during high-speed navigation are reduced, thereby greatly reducing wave-making resistance; and the stability and seakeeping performance of the vessel under severe sea conditions are also taken into account.

The application discloses a marine bottom shielding structure combining a cabin bottom shielding structure and a stack bottom shielding structure, which comprises the cabin bottom shielding structure and the stack bottom shielding structure located on the lower plate of the double bottom of a ship body, and a stack cabin shielding structure and a primary shielding structure located on the upper plate of the double bottom of the ship body, wherein the primary shielding structure is wrapped outside a reactor pressure vessel, the stack cabin shielding structure is located outside the primary shielding structure, the cabin bottom shielding structure is located outside the stack bottom shielding structure, and the stack bottom shielding structure is located below the primary shielding structure. The marine bottom shielding structure combining the cabin bottom shielding structure and the stack bottom shielding structure has simple structure, can form a complete radiation shielding system together with the stack cabin shielding structure, the primary shielding structure and seawater below the ship body, and can weaken the radiation leakage of the stack cabin to the surrounding area to the maximum extent, so as to ensure the radiation safety of personnel and equipment in the surrounding area.

A ship body is provided with the double-layer bottom composed of an inner bottom plate and an outer bottom plate, inner bottom longitudinal ribs are arranged between the inner bottom plate and the outer bottom plate and on the inner bottom plate, outer bottom longitudinal ribs are arranged on the outer bottom plate, the pipe supporting tool is arranged between the inner bottom plate and the outer bottom plate, the pipe supporting tool is provided with a long-strip-shaped round pipe body, and the long-strip-shaped round pipe body is provided with a long-strip-shaped round pipe body. Square sealing plates are arranged at the two ends of the round pipe, and clamps are fixed outside the sealing plates. The clamp is vertically arranged between the inner bottom plate and the outer bottom plate, the inner bottom longitudinal bone and the outer bottom longitudinal bone are located at the two ends of the clamp respectively, inserted into a clamping groove formed by the two limiting plates and fixed through bolts in an abutting mode, and the multiple pipe supporting tools are arranged between the inner bottom plate and the outer bottom plate at equal intervals. The device is used for conducting temporary structural reinforcement on the area, where stress exceeds the standard, of the double-layer bottom structure in the ship launching process of slipway construction, the pressure bearing capacity of the double-layer bottom structure is enhanced, the bearing capacity of the ship bottom structure in the slipway area is effectively improved, and safe launching of the ship for slipway construction is achieved.

A pleasure craft is provided such as a luxury pleasure craft. The craft eliminates the need for transverse bulkheads in one or more decks inside the hull of the craft, thus improving the aesthetics and usability thereof. The hull of the pleasure craft defines an imaginary or virtual freeboard deck located below the main deck of the craft. A cavity is arranged on one or more decks on both sides of the hull separate from the remaining space of the corresponding deck and delimited on its outer side by the corresponding side wall. The imaginary or virtual freeboard deck is therefore at a height equal to the extension in the vertical direction of the cavities from the floor of the corresponding deck.

The invention belongs to the technical field of ship connecting devices, and particularly discloses a ship body connecting device of an assembled cutter suction dredger, which comprises a first connecting assembly A and a second connecting assembly B. The first connecting assembly A is used for connecting ship body structures except a ship bottom plate, and the second connecting assembly B is used for connecting the ship bottom plate. The second connecting assembly B comprises a male connector, a female connector, a first screw rod, a first nut, an adjusting mechanism and a sealing mechanism. By arranging the adjusting mechanism, when the male connector and the female connector are connected, the connecting pipe can be adjusted according to the position between the female connector and the male connector, and after the connecting pipe and the inserting hole of the female connector are kept coaxial, the first screw can be easily inserted into the connecting pipe from the inserting hole of the female connector, so that the connecting pipe can be conveniently connected. The problem that accurate butt joint of the two ship bodies cannot be achieved due to deviation of the positions of the male connector and the female connector is solved, and the convenience and accuracy of ship body connection are improved.

The invention relates to the field of shipbuilding equipment.The anti-shearing structure of the container ship cabin comprises an outer plate, a double-layer bottom is arranged at the bottom end of the outer plate, a deck platform is horizontally arranged in the outer plate, an inner longitudinal wall is vertically arranged in the outer plate, the inner longitudinal wall is fixedly connected with the deck platform, and the inner longitudinal wall is fixedly connected with the deck platform. And the inner longitudinal wall is fixedly connected with the outer plate. The structure can be rapidly arranged, the cabin separation requirement of a cabin can be met, the effect of supporting a cabin deck can be achieved, the thickness of a hatch coaming is reduced, and the structure weight and the shipbuilding cost are reduced.

The invention provides a ship double-layer bottom structure which is characterized in that a plurality of mounting parts are arranged in the width range of each container area, and on an inner bottom plate, the mounting parts corresponding to the two sides of the width of each container area are container corner mounting parts; the pipe tunnel longitudinal girder is arranged on the box corner mounting part close to the center line of the ship body; the distance between every two adjacent reinforcing longitudinal girders in the width direction of the ship body is 1-2 times of the width of the container area. And the longitudinal ribs corresponding to the box corner mounting parts are box corner reinforcing longitudinal ribs. According to the double-layer bottom structure of the ship, the installation positions and the arrangement modes of the trusses and the longitudinal bones are limited, on the premise that the structural strength is ensured, construction can be completed through a small number of structural parts, and therefore the construction efficiency is improved, and the construction cost is reduced.
