Description

Technical Field

[0001] The utility model relates to the technical field of marine ship equipment, in particular to a novel deck transport ship. Background Art

[0002] A deck carrier is a type of ship with no cargo hold within the main hull, using the deck as a loading platform. It can be used to carry dry goods, packaged goods, bulk cargo such as coal, grain, and ore, as well as large-scale land and sea engineering equipment and facilities. While deck carriers are relatively common today, they still present some challenges, such as high resistance to navigation, insufficient propulsion performance, and inconvenient cargo handling. Utility Model Content

[0003] In view of this, in order to solve the above-mentioned problems such as large resistance, insufficient propulsion performance, and inconvenient cargo handling, an embodiment of the present utility model provides a new type of deck transport ship.

[0004] An embodiment of the present utility model provides a novel deck transport ship, comprising a hull;

[0005] One end of the hull is the bow body of the ship, and the other end is the stern body of the ship. The bow body of the ship is upright in shape, and a bow thruster is provided at the lower part thereof. Propellers are provided on both sides of the stern body of the ship. A deck fence is built on the upper surface of the hull. The area enclosed by the deck fence is the cargo storage area, and a number of container holders are arranged in an array in the cargo storage area. A retractable vehicle gangway is provided on the side of the deck fence close to the bow body of the ship to allow trucks from outside to transport goods into the cargo storage area.

[0006] Furthermore, a driving cabin is built near the bow body of the ship and on the hull.

[0007] Furthermore, an engine room chimney is constructed near the stern body of the ship and on the hull.

[0008] Furthermore, an inspection passage is provided at the upper end of the deck fence, and a ladder is built outside the inspection passage.

[0009] Furthermore, each of the propellers is a twin-propeller.

[0010] Furthermore, the external waterline is located within the vertical range of the bow body of the ship, and the top end of the bow body of the ship is tilted forward and the bottom end is rounded.

[0011] Furthermore, the tail body of the ship adopts an asymmetric double-tail type.

[0012] The beneficial effects brought about by the technical solution provided by the embodiment of the present utility model are: first, the outer shape of the bow body of the ship is upright. When the hull is operating in the ocean, the waterline is located within the vertical range of the bow body of the ship, so that the underwater part of the bow body of the ship can be upright, lengthening the waterline length, reducing the bow inflow angle, and reducing the bow resistance; the above-water part of the bow remains upright, which can reduce the bow impact and is beneficial to the wavekeeping of the ship; second, a number of container holders are arranged in an array in the cargo storage area, which can play a relatively stable role for the cargo box; third, by arranging a retractable vehicle gangway, it is convenient for trucks to enter the cargo storage area, and combined with the deck fence, safer and more efficient loading or unloading can be achieved without the need for dock loading and unloading equipment.

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to Figures 1 to 2 An embodiment of the present utility model provides a new type of deck transport ship, including a hull 1.

[0018] In this embodiment, one end of the hull 1 is the bow body 2 and the other end is the stern body 3. In actual circumstances, the bow body 2 is the forward end of the hull and the stern body 3 is the stern of the hull. When the hull 1 drives forward, the bow body 2 will be impacted by seawater.

[0019] Furthermore, the overall shape of the bow body 2 of the ship is upright, and when the hull 1 is driven forward, the external waterline is located within the vertical range of the bow body 2 of the ship. In other words, the draft surface is located in the middle of the bow body 2 of the ship. When the hull 1 moves, the bow body 2 of the ship overcomes the obstruction of seawater and moves forward. Since the waterline is located within the vertical range of the bow body 2 of the ship, the underwater part of the forward end of the entire hull 1 can be upright, which can lengthen the waterline length, reduce the bow inflow angle, and reduce the bow resistance. At the same time, the above-water part also remains upright, which can reduce the bow impact and is beneficial to the wavekeeping of the ship.

[0020] It should be noted here that in order to minimize resistance, the connection between the lower end of the bow body 2 and the bottom of the hull 1 is chamfered, and the upper end of the bow body 2 is tilted forward.

[0021] A bow thruster 4 is provided on the hull 1 below the bow body 2 of the ship. The bow thruster 4 is used to assist the hull 1 in steering when necessary. A driving cabin 5 is provided on the hull 1 near the bow body 2 of the ship.

[0022] In this embodiment, the shape of the ship's stern body 3 adopts an asymmetric double-tail type, the tail line changes relatively gently, the longitudinal gradient changes little, the tail flow field is smooth, the lateral flow is significantly reduced, and a longitudinal flow trend is caused, ultimately achieving the effect of reducing resistance and increasing effective wake.

[0023] Propellers 6 are provided on both sides of the stern body 3 and on the hull 1. In this embodiment, each propeller is a twin-screw propeller. It should be noted here that twin-screw propellers are a relatively mature technology, so they will not be described in detail here.

[0024] An engine room chimney 7 is provided on one end of the hull 1 close to the stern body 3 of the ship. In actual working conditions, the engine room chimney is connected to the driving equipment in the hull 1 to achieve the purpose of smoke exhaust.

[0025] A deck railing 8 surrounds the upper surface of the hull 1. The area formed by the deck railing 8 serves as a cargo storage area 12. When cargo is needed, it is stacked within the cargo storage area. Within the cargo storage area 12, a number of container holders 13 are arranged in an array, each used to secure loaded containers. An inspection passage 9 is located atop the deck railing 8, allowing for cargo inspections when necessary. A ladder 10 is mounted on the outer wall of the deck railing 8, allowing personnel to access the inspection passage 9 when necessary. It should be noted that a pedestrian walkway is provided between the outer wall of the deck railing 8 and the edge of the hull 1.

[0026] Furthermore, a retractable vehicle ramp 11 is provided on one side of the deck fence close to the bow body of the ship, and the vehicle ramp 11 is used to allow trucks to enter or leave the cargo storage area 12 through the vehicle ramp 11 when loading or unloading.

[0027] A new type of deck transport vessel in this embodiment mainly ensures that the bow of the ship above and below the waterline is upright through the upright design of its forward end, thereby lengthening the waterline length, reducing the bow inflow angle, reducing the bow resistance, and reducing the bow impact; at the same time, the upright bow and asymmetric double-tail stern of the ship can reduce the ship resistance and increase the propulsion efficiency. Compared with ships of similar size, the bollard drag can be increased, and the propulsion fuel consumption rate at the same speed can be reduced.

[0028] In this document, directional terms such as front, back, top, and bottom are defined based on the positions of components in the accompanying drawings and relative to each other, and are intended only for clarity and convenience in describing the technical solution. It should be understood that the use of these directional terms should not limit the scope of protection claimed in this application.

[0029] In the absence of conflict, the above embodiments and features in the embodiments may be combined with each other.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
