Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a large gas transport ship capable of eliminating blind spots in visual field. Background Art

[0002] In the design and operation of large gas carriers (such as LNG carriers, LPG carriers, etc.), in order to meet the needs of long-distance and large-capacity transportation, several large fuel tanks are usually arranged on the deck. As the main container for storing liquefied gases (such as LNG and LPG), the fuel tank is huge in size. Due to its height and width, it will block the operator's direct line of sight to the front, sides and part of the rear area, forming some blind spots. The ventilation mast, as an important part of the ship's ventilation system, is responsible for discharging inert or harmful gases accumulated in the tank to ensure the safety of the ship. The layout of the two on the deck often restricts each other. They must meet their respective functional requirements while minimizing the impact on each other and the operator's vision.

[0003] However, in actual design, due to space limitations and functional requirements, it is often difficult to completely avoid the fuel tank and the breather mast from each other. Especially in areas such as the bow and stern, the layout of the fuel tank may directly block the breather mast, or the breather mast may be positioned too high, forming a visual obstruction with the fuel tank. This layout not only affects the normal operation of the breather mast, but more importantly, it greatly limits the operator's field of vision. When the fuel tank and the breather mast block each other, the operator's field of vision is severely restricted, forming a significant blind spot. In addition, the large size and complex hull structure of large gas tankers also exacerbate the problem of limited vision. Complex structures such as the ship's superstructure, masts, booms, cables, etc. may become obstacles to vision, especially in areas with dense hull structures such as the bow and stern, resulting in multiple blind spots, further increasing navigation risks. These blind spots may cover the front, sides, and even part of the rear area, making it difficult for the operator to obtain comprehensive environmental information during critical operations such as navigation, berthing, and collision avoidance. Specifically, blind spots can lead to the following problems:

[0004] (1) Difficulty in collision avoidance: Due to the inability to clearly see obstacles in front or on the side, the operator may make wrong judgments during the collision avoidance process, increasing the risk of collision.

[0005] (2) Improper channel selection: Limited vision will cause the operator to be unable to accurately judge the channel conditions and choose an inappropriate channel, which will affect navigation safety.

[0006] (3) Berthing errors: During the berthing process, the blind spot of vision causes the operator to be unable to accurately grasp the distance and angle between the dock and the ship, resulting in berthing errors.

[0007] (4) Insufficient control over the ship's dynamic performance: Limited vision affects the operator's control over the ship's dynamic performance, such as speed and heading, increasing the risk of the ship losing control. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the invention.

[0032] like Figure 1-7 As shown, the utility model provides a large gas transport ship capable of eliminating blind spots in vision, comprising: a hull comprising a bow, a hull and a stern;

[0033] A command room is provided at the stern, and a command area 1 is provided in the command room; a platform 6 is provided in the command area 1, and the platform 6 can increase the observation height and angle to eliminate blind spots in the field of vision; and / or an image acquisition device 4 is provided outside the command room, and a display terminal is provided directly above the command area 1 and is communicatively connected to the image acquisition device 4. The image acquisition device 4 is used to collect real-time video images of the surrounding environment of the large gas tanker from various angles and send them to the display terminal for display.

[0034] The large gas tanker of the present invention can eliminate blind spots in vision. A platform is provided in the command area to increase the observation height and angle, so that when the observer stands on the platform, he can see the sea situation in the distance more clearly, eliminating blind spots in vision; and / or the image acquisition device captures real-time video images of the surrounding environment at various angles of the hull, and transmits the real-time video images of the surrounding environment at various angles of the hull to the display terminal in real time for the observer to view. The image acquisition device effectively eliminates blind spots in vision through all-round and no-dead-angle monitoring. The observer only needs to use the display terminal to fully understand the situation around the hull, forming a wider field of vision, such as the bottom, side or rear of the ship. Therefore, by eliminating blind spots in vision, the observer can more comprehensively grasp the environmental information around the ship, which helps to discover potential dangerous factors in advance, thereby making more accurate and timely decisions, improving the operability of the ship, making operation simpler, and correctly mooring to avoid collisions, thereby improving the safety and seaworthiness of the ship's navigation. In complex waters or severe weather conditions, a wider field of view helps observers better plan routes, avoid unnecessary detours or delays, and improve navigation efficiency.

[0035] In this embodiment, if Figure 1-4 As shown, according to actual needs, the platform 6 can be provided only in the command area 1, or the image acquisition device 4 can be provided outside the command room, and a display terminal can be provided directly above the command area 1 to communicate with the image acquisition device 4. Alternatively, a platform can be provided in the command area 1, and an image acquisition device 4 can be provided outside the command room, and a display terminal can be provided directly above the command area 1 to communicate with the image acquisition device 4.

[0036] In this embodiment, if Figure 5-6 As shown, when there is no platform or image acquisition device 4, the deck fuel tanks 2 and the ventilation masts 3 are arranged on the main deck, causing mutual interference. There are two deck fuel tanks 2. Due to their large size and high height, they block the view of the observer 7. Although the ventilation masts 3 are relatively small, they are often located high and protruding, which has a certain impact on the view of the observer 7. In particular, the ventilation masts 3 arranged near the deck fuel tanks 2 are more likely to form a blind spot with the deck tanks, making it difficult for the observer 7 to observe certain key areas. Figure 6 As shown, blind spots ①, ②, and ③ are formed. The angle range of blind spot ① is 3.2°, the angle range of blind spot ② is 2°, and the angle range of blind spot ③ is 2.2°, which poses a challenge to the safe navigation and efficient operation of the ship.

[0037] It is worth noting that if Figure 1-2As shown, a platform 6 is provided in the command area 1, relative to Figure 3 As shown in the visual observation point, the visual angle of the observer 7 rises, forming a new visual observation point G, eliminating the blind spot of the visual field, so that the observer 7 can more comprehensively grasp the environmental information around the ship. Figure 3-4 As shown, an image acquisition device 4 is set outside the command room, relative to Figure 5 As shown in the visual observation point G, the sight angle of the image collection is increased, and real-time video images of the environment around the hull can be collected from various angles and transmitted to the display terminal in real time for the observer 7 to view. The image collection device 4 effectively eliminates blind spots through all-round and no-dead-angle monitoring. The observer 7 only needs to use the display terminal to fully understand the situation around the hull, forming a wider field of view, such as the bottom, side or rear of the ship. By eliminating blind spots, the observer 7 can more comprehensively grasp the environmental information around the ship, which helps to discover potential dangerous factors in advance, thereby making more accurate and timely decisions, improving the operability of the ship and making operation easier.

[0038] In this embodiment, the platform 6 comprises multiple observation platforms, each offering a different field of view at different heights and angles. This allows observers 7 to comprehensively monitor the vessel's navigation environment and surrounding waters, significantly reducing blind spots and effectively preventing obstructions to vision caused by the vessel's structure. This multi-layered observation platform allows observers 7 to detect potential navigation obstacles or dangerous situations earlier, effectively ensuring the vessel's safe navigation. This comprehensive field of view helps observers 7 more accurately assess navigation conditions, enabling more scientific and rational route planning and improving navigation efficiency.

[0039] In this embodiment, the platform 6 comprises a lifting platform equipped with a drive motor that drives the platform up and down to provide views at different heights and angles. As the lifting platform moves up and down, the observer 7 can obtain views from different angles, from low to high, thereby gaining a more comprehensive understanding of the vessel's surrounding environment and dynamics. By adjusting the observation height, blind spots caused by obstructions caused by the vessel's structure can be effectively reduced, improving the accuracy and comprehensiveness of observations and providing earlier warnings for the vessel's navigation safety. Comprehensive visual coverage helps the observer 7 more accurately assess navigation conditions, enabling more scientific and rational decision-making and improving navigation efficiency.

[0040] In this embodiment, by adding a platform 6 at the command position and / or adding an image acquisition device 4 outside the command room, the blind spots of vision are eliminated, and the observer 7 can complete the observation task more easily, reducing the workload caused by long-term target searching or distance judgment, improving the operability of the ship, making the ship operation simpler, and improving the navigation safety and efficiency of the ship, enhancing the market competitiveness and overall value of the ship, enabling the ship to better adapt to different navigation environments and climatic conditions, and improving the adaptability and flexibility of the ship.

[0041] In this embodiment, if Figure 1 、 3 As shown, a signal tower 5 is also provided at the stern of the ship, and the image acquisition device 4 is provided on the signal tower 5. The signal tower 5 plays multiple roles for the ship during navigation at sea, such as navigation guidance, visual aid, and communication information service. These functions together constitute an important guarantee for the safety and smoothness of maritime traffic.

[0042] In this embodiment, the image acquisition device 4 includes but is not limited to: a camera, a video camera, a camera module integrated with an optical system or a CCD chip, a camera module integrated with an optical system and a CMOS chip, etc.

[0043] In this embodiment, if Figure 7 As shown, the height range of the platform 6 is 180-250 mm. Figure 7 The platform height shown is only one embodiment of the present invention and is not intended to limit the scope of protection of the present invention. In practice, the platform height is set according to actual conditions.

[0044] In this embodiment, a main deck is provided on the upper surface of the hull, and one or more low-temperature and high-pressure deck fuel tanks 2 are provided on the main deck. The low-temperature and high-pressure deck fuel tanks 2 store low-temperature and high-pressure LPG.

[0045] In this embodiment, fuel preparation equipment is also installed on the main deck, connected to the low-temperature, high-pressure deck fuel tank 2 via a booster pipeline. An engine is installed within the stern, and the fuel preparation equipment is connected to the engine via a gas pipeline. LPG delivered from the low-temperature, high-pressure deck fuel tank 2 is pressurized and heated by the fuel preparation equipment before being delivered to the engine via the gas pipeline. The fuel preparation equipment is located on the main deck near the stern and includes a booster pump and a heat exchanger.

[0046] In this embodiment, the LPG booster pump is installed on the main deck and is connected to the low-temperature and high-pressure deck fuel tank 2 through a booster pipeline; the heat exchanger is connected to the LPG booster pump and is connected to the engine through a gas pipeline; the LPG delivered from the low-temperature and high-pressure deck fuel tank 2 is pressurized and heated by the LPG booster pump and the heat exchanger, and then delivered to the engine through the gas pipeline.

[0047] In this embodiment, a ventilation mast 3 for gas discharge and treatment is also provided on the main deck. The timely discharge of excess gas through the ventilation mast 3 can effectively prevent the liquid cargo tank from being damaged due to overpressure, thereby ensuring the integrity and sealing of the tank.

[0048] In this embodiment, the display terminal includes a display screen. The display screen is communicatively connected to the image acquisition device 4. The observer 7 can fully understand the situation around the ship through the display screen, more comprehensively grasp the environmental information around the ship, and help to identify potential hazards in advance, thereby making more accurate and timely decisions, improving the operability of the ship and making it easier to operate.

[0049] In this embodiment, the ship further comprises a plurality of cryogenic storage tanks, which are sequentially arranged along the bow and stern directions of the ship below the main deck. The gas transported by the large gas tanker is stored in the cryogenic storage tanks.

[0050] In summary, the present application provides a large gas tanker that can eliminate blind spots in vision. A platform is provided in the command area to increase the observation height and angle, so that when the observer stands on the platform, he can see the sea situation in the distance more clearly, eliminating blind spots in vision; and / or the image acquisition device captures real-time video images of the surrounding environment at various angles of the hull, and transmits the real-time video images of the surrounding environment at various angles of the hull to the display terminal in real time for the observer to view. The image acquisition device effectively eliminates blind spots in vision through all-round and no-dead-angle monitoring. The observer only needs to use the display terminal to fully understand the situation around the hull, forming a wider field of vision, such as the bottom, side or rear of the ship. By eliminating blind spots in vision, the observer can more comprehensively grasp the environmental information around the ship, which helps to discover potential dangerous factors in advance, thereby making more accurate and timely decisions, improving the operability of the ship, making operation simpler, correctly mooring, avoiding collisions, and improving the safety and seaworthiness of the ship's navigation.
