Description

Technical Field

[0001] The present invention relates to the technical field of ships and marine engineering, and in particular to a three-hull ship. Background Art

[0002] Most of the existing open-hull transport ships are double-hull ships, and their rotating shafts are mostly arranged at the center line of the deck. This arrangement of the rotating shaft causes the superstructure to be connected to both sides of the double-hull ship in a sliding manner. During the opening and closing process of the hull, the connection between the two sides of the superstructure and the main hull will slide along the slide rails. This method will not only increase the difficulty of ship construction, but also lead to low strength at the connection between the hull and the superstructure. In addition, the load at the center line of the ship deck is generally large, and setting the rotating shaft at the center line of the deck poses strength and safety hazards; finally, the size of the bottom opening of the double-hull ship is all achieved by rotating the rotating shaft at the center line of the deck, and coupled with the limitation of the connection between the superstructure and the main hull, the maximum limit value of the opening is relatively small. Therefore, its ability to fold and unfold large-sized cargo is poor. If it is transported by hoisting, it is easy to cause collision between the cargo and the hull under high sea conditions, and it is difficult to complete the folding and unfolding of large-sized cargo safely and efficiently within a short window period. Due to the aforementioned reasons, the strength of the existing open-body ship deck and the connection between the superstructure and the main ship is low, and it is difficult to safely and efficiently complete the storage and delivery of large-sized cargo within a short window period. Summary of the invention

[0003] Aiming at the problem that the deck of the current open-hull ship and the strength difference between the superstructure and the main ship are low, and it is difficult to complete the storage and delivery of large-sized cargo safely and efficiently within a short window period, a three-open-hull ship type is proposed.

[0004] The technical solution of the present invention is: a three-body ship, comprising a hull, a rotation shaft symmetrically arranged on a deck along the central axis of the hull, the deck comprising a middle plate, two sides of the middle plate are respectively connected to a first side deck and a second side deck through a rotation shaft, the side is fixedly connected to the first side deck and the second side deck, and the entire side of the two sides rotates with the rotation of the first side deck and the second side deck;

[0005] Bilges are provided at the lower ends of the sides of the hull, and bottom outer plates are provided at the bottom of the ship. Connecting devices are provided at both ends of the bottom outer plates, and the two ends of the bottom outer plates are movably connected to the bilges through the connecting devices. The bottom outer plates can be lowered into deep water areas through the connecting devices.

[0006] Preferably, the hull is provided with outboard engine rooms on both sides near the stern, wherein an engine for a steering propeller is provided in the outboard engine room on one side, and an engine for a deck rotating shaft is provided in the engine room on the other side, and the steering propeller engine drives the steering propellers on both sides of the hull through a transmission device.

[0007] Preferably, the deck rotating shaft is driven by an engine through a rotation drive device.

[0008] Preferably, a streamlined watertight peak cabin is provided at the end of the outboard engine room away from the stern.

[0009] Preferably, the hull is provided with a cargo hold, and the cargo hold is a fully through structure.

[0010] Preferably, a superstructure is provided on the top surface of the outboard engine room, and a lookout system is provided above the superstructure.

[0011] Preferably, the distance L1 between the side wall of the superstructure close to the midship and the midship axis is not less than (L2 / 2+R), where L2 is the distance between the center lines of the rotating shafts and R is the radius of the rotating shafts.

[0012] Preferably, the superstructure height H1 above the deck does not exceed (L2 / 2+R) / SINθ, where θ is the rotation angle of the rotation axis.

[0013] Preferably, watertight compartments are provided inside the bilges on both sides of the ship bottom, and driving devices are provided inside the watertight compartments.

[0014] Preferably, the driving device drives the bottom outer plate of the ship through the connecting device, so that the bottom outer plate of the ship is lowered to a deeper level underwater, and the cargo in the cargo hold is lowered to a deep water area.

[0015] The beneficial effects of the present invention are as follows: compared with the prior art, the three-hull superstructure and the main deck provided by the present invention adopt a fixed welding method, and the strength of the connection is relatively high. Moreover, due to the use of a double rotating shaft on the deck, not only can a larger bottom opening be achieved by rotating at a smaller angle, but the installation position of the rotating shaft can also be avoided from the high stress area of ​​the deck. In addition, the outer plate of the bottom can be lowered into the deep water area through the connecting device, providing sufficient space for the storage and release of large-sized cargo, which can effectively ensure that the ship can safely and efficiently complete the storage and release of large-sized cargo within a relatively short window period.
