Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of marine and ocean engineering, in particular to a three-opening-body ship type. BACKGROUND

[0002] The existing opening-body transport ship is mostly a double-opening-body ship, and the rotating shaft is mostly arranged at the deck center line. This arrangement of the rotating shaft causes the superstructure to be connected to the two sides of the double-opening-body ship in a sliding manner. During the opening and closing of the ship body, the two sides of the superstructure connected to the main ship body slide along the slide rail. This not only increases the difficulty of ship construction, but also causes the connection between the ship body and the superstructure to have low strength. In addition, the load at the deck center line is generally large, and there is a strength and safety hazard in arranging the rotating shaft at the deck center line. Finally, the opening size of the double-opening-body ship is realized by rotating the rotating shaft at the deck center line, and the maximum limit of the opening is relatively small due to the restriction of the connection between the superstructure and the main ship body. Therefore, the ship has poor capacity for loading and unloading large-size cargo, and if the cargo is transported by hoisting, the cargo is likely to collide with the ship body in high sea conditions, and it is difficult to safely and efficiently complete the loading and unloading of large-size cargo in a short window period. Due to the foregoing reasons, the strength of the deck and the connection between the superstructure and the main ship of the existing opening-body ship type is low, and it is difficult to safely and efficiently complete the loading and unloading of large-size cargo in a short window period. SUMMARY

[0003] In view of the low strength of the deck and the connection between the superstructure and the main ship of the existing opening-body ship type, and the difficulty in safely and efficiently completing the loading and unloading of large-size cargo in a short window period, a three-opening-body ship type is provided.

[0004] The technical scheme of the present application is as follows: a three-opening-body ship type, comprising a ship body, a rotating shaft symmetrically arranged on a deck along a central axis of the ship body, the deck comprising a middle plate, the middle plate being connected to a first side deck and a second side deck on both sides through the rotating shaft, the side of the ship body being fixedly connected to the first side deck and the second side deck, and the entire side of the ship body on both sides rotating with the first side deck and the second side deck.

[0005] The lower end of the side of the ship body on both sides is provided with a bilge, the bottom is provided with a bottom plate, and the two ends of the bottom plate are provided with a connecting device. The two ends of the bottom plate are movably connected to the bilge through the connecting device, and the bottom plate can be lowered to a deep water area through the connecting device.

[0006] Preferably, the ship body is provided with an outboard engine room near the two sides of the stern, an engine for rudder propeller is arranged in one side of the outboard engine room, and an engine for rotating the deck shaft is arranged in the other side of the outboard engine room. The engine for rudder propeller drives the rudder propeller on both sides of the ship body 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 tank 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 rotation axes and R is the radius of the rotation axes.

[0012] Preferably, the height H1 of the superstructure 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 bottom of the ship, and a driving device is 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 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 deployment of large-sized cargo, which can effectively ensure that the ship can complete the storage and deployment of large-sized cargo safely and efficiently within a relatively short window period.

In this embodiment, the transmission device 4 and the rotary drive device 5 can be transmission shafts, and the transmission device 4 and the rotary drive device 5 can be connected to the components driven by them through gear sets or belts, etc., which are not limited to a specific device;

[0028] A propeller is provided on the outside of the outboard engine room 12 near the stern, and the propellers are coaxially connected to the engines for connecting the rudder propellers. A rudder is provided on the lower side of the stern near the stern end of the propeller.

The middle plate 111 is fixed, while the first side deck 112 and the second side deck 113 can rotate around the rotation axis 6. The side 15 is fixedly connected to the first side deck 112 and the second side deck 113. Therefore, the entire side 15 on both sides can rotate with the rotation of the first side deck 112 and the second side deck 113.

[0030] refer to Figure 1 、 5 As shown, a streamlined watertight peak tank 121 is provided at one end of the outboard engine room 12 away from the stern;

At this time, the rotating shaft 6 rotates, the deck 11 and the side 15 are opened to both sides, and the driving device 9 drives the bottom outer plate 14 through the connecting device 8, so that the bottom outer plate 14 and the cargo in the cargo hold 17 are lowered to a deeper depth underwater, providing sufficient space for stowage and stowage of large-sized cargo. At the same time, in this state, water enters the cargo hold 17, and the hull floats on the water surface by relying on the watertight void spaces 131 on both sides.
