Description

Technical Field

[0001] The utility model relates to the technical field of oil suction devices, and more specifically, to a floating oil suction device for a ship. Background Art

[0002] In the context of global economic integration, the international shipping industry plays a vital role. However, with the continuous rise in fuel prices, shipping costs have also risen, bringing great economic pressure to shipping companies. In order to meet this challenge, many ships have begun to use heavy oil as fuel, because heavy oil has a lower cost than traditional fuel. Using heavy oil as fuel is not without risk. A key problem is that most heavy oil suction ports are fixed at the bottom of the heavy oil tank, very close to the bottom of the tank. During long-term use, due to the large specific gravity of water and impurities, they will naturally settle at the bottom of the heavy oil tank. Once these sediments accumulate to a certain extent, they are easily sucked into the fuel pipeline by the heavy oil suction port. Once these fuels containing water and impurities are pumped into the main engine of the ship, they will seriously affect the normal operation of the main engine and may even cause damage to the main engine. This will not only bring great safety hazards to the navigation of the ship, but also cause huge economic losses. Therefore, it is necessary to improve and optimize it. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a marine floating oil suction device, which has the advantages of convenient disassembly and assembly and good stability.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a ship-based floating oil suction device, comprising an oil storage tank, a connecting pipe is fixedly installed on the inner wall of the oil storage tank, the connecting pipe runs through the oil storage tank, a connecting block is fixedly installed on the right end of the connecting pipe, two fixed blocks are fixedly installed on the bottom inner wall of the oil storage tank, the inner walls of the two fixed blocks are hinged to the connecting blocks, an oil suction pipe 1 is fixedly installed on the right side of the connecting block, an oil suction pipe 2 is fixedly installed on the top of the oil suction pipe 1, an oil suction pipe 3 is fixedly installed on the right end of the oil suction pipe 2, an oil suction end is fixedly installed on the top of the oil suction pipe 3, a main buoy is provided on the top of the oil suction pipe 2, and a connecting rope is wound around the outer wall of the main buoy and the outer wall of the oil suction pipe 2.

[0005] As a preferred technical solution of the utility model, two fixing frames are fixedly installed on the outer wall of the oil suction pipe 1, and auxiliary buoys are respectively provided on the inner walls of the two fixing frames. The two auxiliary buoys are fixed to the fixing frames by nut and bolt assemblies.

[0006] As a preferred technical solution of the utility model, the outer shape of the fixing frame is composed of three circles, wherein the inner diameter of the middle circle is the same as the outer diameter of a cross section of the oil suction pipe.

[0007] As a preferred technical solution of the utility model, the other two circles of the fixing frame are in an open shape, and two protrusions are fixedly installed at the openings.

[0008] As a preferred technical solution of the utility model, the top of the oil suction end is set to be funnel-shaped, and the bottom is set to be a hollow cylinder. The bottom cross-sectional diameter of the oil suction end is the same as the cross-sectional diameter of the oil suction pipe three.

[0009] As a preferred technical solution of the utility model, the oil suction pipe 1, the oil suction pipe 2, the oil suction pipe 3 and the oil suction end are all fixedly connected by a flange.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The utility model provides buoyancy for the entire oil suction system by arranging a main float installed on the top of the second oil suction pipe, so that the height can be automatically adjusted as the fuel level changes, ensuring that the oil suction end is always kept below the fuel level; the connecting rope is simultaneously wound around the outer wall of the main float and the second oil suction pipe, playing the role of fixing and limiting the moving range of the main float, preventing it from excessively rising or shaking under the action of buoyancy. Compared with the traditional device, the oil suction end of the device can float up and down with the rise and fall of the liquid level, and always extract the surface layer of fuel. Due to the floating effect of moisture and impurities in the gravity field, the moisture and impurities in the upper layer of fuel are always lower than the bottom oil layer. Therefore, extracting the upper layer of fuel can ensure the emission of cleaner fuel and extend the service life of the downstream purification equipment.

[0012] 2. The utility model adopts the nut and bolt assembly to make the connection between the auxiliary buoy and the fixing frame both firm and easy to adjust. When the auxiliary buoy or the fixing frame needs to be maintained or replaced, the parts can be easily removed by simply loosening the nut and bolt assembly. This design simplifies the maintenance process and reduces maintenance costs. The tightness of the nut and bolt assembly ensures a stable connection between the auxiliary buoy and the fixing frame, thereby reducing the safety hazards caused by loose connections. The nut and bolt assembly connection method can also withstand certain vibrations and impacts, ensuring the stable operation of the device in harsh environments. Compared with traditional devices, this design is more in line with the needs and development trends of the modern shipbuilding industry. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 6 As shown, the utility model provides a marine floating oil suction device, including an oil storage tank 1, a connecting pipe 2 is fixedly installed on the inner wall of the oil storage tank 1, the connecting pipe 2 runs through the oil storage tank 1, a connecting block 4 is fixedly installed on the right end of the connecting pipe 2, two fixed blocks 3 are fixedly installed on the bottom inner wall of the oil storage tank 1, the inner walls of the two fixed blocks 3 are hinged to the connecting block 4, an oil suction pipe 1 5 is fixedly installed on the right side of the connecting block 4, an oil suction pipe 2 6 is fixedly installed on the top of the oil suction pipe 1 5, an oil suction pipe 3 7 is fixedly installed on the right end of the oil suction pipe 2 6, an oil suction end 8 is fixedly installed on the top of the oil suction pipe 3 7, a main buoy 12 is arranged on the top of the oil suction pipe 2 6, and a connecting rope 13 is wound around the outer wall of the main buoy 12 and the outer wall of the oil suction pipe 2 6.

[0022] By setting the main float 12 to be installed on the top of the oil suction pipe 6, buoyancy is provided for the entire oil suction system, so that it can automatically adjust its height as the fuel level changes, ensuring that the oil suction end always remains below the fuel level; the connecting rope 13 is simultaneously wrapped around the outer wall of the main float 12 and the oil suction pipe 6, playing the role of fixing and limiting the movement range of the main float, preventing it from excessively rising or shaking under the action of buoyancy. Compared with traditional devices, the oil suction end 8 of the device can float up and down with the rise and fall of the liquid level, and always extract the surface layer of fuel. Due to the floating effect of moisture and impurities in the gravity field, the moisture and impurities in the upper layer of fuel are always lower than the bottom oil layer. Therefore, extracting the upper layer of fuel can ensure the emission of cleaner fuel and extend the service life of the downstream purification equipment.

[0023] The staff first fixes the connecting pipe 2 on the inner wall of the oil storage tank 1, ensuring that the connecting pipe 2 passes through the oil storage tank 1, the left end extends out of the heavy oil tank and connects to the main engine oil supply system on board, and the right end is connected to the connecting block 4. The oil suction pipe 1 5 is installed on the right side of the connecting block 4, and it is ensured to be firmly connected to the connecting block 4. The oil suction pipe 2 6, the oil suction pipe 3 7 and the oil suction end 8 are installed in turn. All oil suction pipes and the oil suction ends are fixedly connected by flanges 14 to ensure sealing and stability.

[0024] Among them, two fixing frames 9 are fixedly installed on the outer wall of the oil suction pipe 5, and auxiliary buoys 11 are respectively provided on the inner walls of the two fixing frames 9. The two auxiliary buoys 11 are fixed to the fixing frames 9 by nut and bolt assemblies 10 respectively.

[0025] By adopting the nut and bolt assembly 10, the connection between the auxiliary buoy 11 and the fixing frame 9 is both firm and easy to adjust. When the auxiliary buoy 11 or the fixing frame 9 needs to be maintained or replaced, the parts can be easily removed by simply loosening the nut and bolt assembly 10. This design simplifies the maintenance process and reduces maintenance costs. The tightness of the nut and bolt assembly 10 ensures a stable connection between the auxiliary buoy 11 and the fixing frame 9, thereby reducing the safety hazards caused by loose connections. The connection method of the nut and bolt assembly 10 can also withstand certain vibrations and impacts, ensuring the stable operation of the device in harsh environments. Compared with traditional devices, this design is more in line with the needs and development trends of the modern shipbuilding industry.

[0026] The staff installs two fixing frames 9 on the outer wall of the oil suction pipe 5, and sets a secondary float 11 on the inner wall of the fixing frame 9, fixes the secondary float 11 to the fixing frame 9 by the nut and bolt assembly 10, sets the main float 12 on the top of the oil suction pipe 6, and wraps the connecting rope 13 around the main float 12 and the outer wall of the oil suction pipe 6 to ensure that the movement range of the main float 12 is limited, and then debugging and inspection are required: before starting to use, debug the entire oil suction device to ensure that all components are firmly connected without looseness or leakage, check the buoyancy status of the main float 12 and the secondary float 11 to ensure that they can automatically adjust their position according to changes in the fuel level, and verify whether the position of the oil suction end 8 is correct to ensure that it can always remain below the fuel level.

[0027] The outer shape of the fixing frame 9 is composed of three circles, wherein the inner diameter of the middle circle is the same as the outer diameter of the cross section of the oil suction pipe 5.

[0028] The inner diameter of the middle circle is completely matched with the outer diameter of the cross section of the oil suction pipe 5, so when the two are combined, they can form a close connection. The size of the middle circle is precise, and the staff does not need to make complicated adjustments or changes during installation. They only need to simply insert the oil suction pipe 5 into the middle circle of the fixing frame 9 to complete the fixation. This not only improves the installation efficiency, but also ensures the stability after installation, so that the entire oil suction device can maintain a stable working state during the operation of the ship.

[0029] The other two circles of the fixing frame 9 are in an open shape, and two protrusions are fixedly mounted at the openings.

[0030] The design of the opening circle allows the fixing frame 9 to adjust its size when necessary to match the outer diameter of different buoys. Whether it is a smaller buoy or a larger buoy, the fixing frame 9 can adapt to it by adjusting the size of the opening circle to ensure a close fit with the buoy.

[0031] Among them, the top of the oil suction end 8 is set to be funnel-shaped, and the bottom is set to be a hollow cylinder. The bottom cross-sectional diameter of the oil suction end 8 is the same as the cross-sectional diameter of the oil suction pipe three 7.

[0032] By arranging the top of the oil suction end 8 into a funnel shape, the collection area of ​​the fuel oil can be increased, so that the oil suction device can more effectively suck the fuel oil from the oil tank.

[0033] Among them, the oil suction pipe 1 5 , the oil suction pipe 2 6 , the oil suction pipe 3 7 and the oil suction end 8 are all fixedly connected by a flange 14 .

[0034] The installation and disassembly process can be greatly simplified by using flange 14 for connection. Since the flange is a standardized connection part, it is only necessary to align the two flanges and tighten them with bolts without complicated welding or riveting processes. This not only improves work efficiency but also reduces installation costs.

[0035] The working principle and use process of this utility model:

[0036] The staff first fixes the connecting pipe 2 on the inner wall of the oil storage tank 1, ensuring that the connecting pipe 2 passes through the oil storage tank 1, the left end extends out of the heavy oil tank and connects to the main engine oil supply system on board, and the right end is connected to the connecting block 4. The oil suction pipe 1 5 is installed on the right side of the connecting block 4, and it is ensured to be firmly connected to the connecting block 4. The oil suction pipe 2 6, the oil suction pipe 3 7 and the oil suction end 8 are installed in turn. All oil suction pipes and the oil suction ends are fixedly connected by flanges 14 to ensure sealing and stability.

[0037] The staff installs two fixing frames 9 on the outer wall of the oil suction pipe 5, and sets a secondary float 11 on the inner wall of the fixing frame 9, fixes the secondary float 11 to the fixing frame 9 by the nut and bolt assembly 10, sets the main float 12 on the top of the oil suction pipe 6, and wraps the connecting rope 13 around the main float 12 and the outer wall of the oil suction pipe 6 to ensure that the movement range of the main float 12 is limited, and then debugging and inspection are required: before starting to use, debug the entire oil suction device to ensure that all components are firmly connected without looseness or leakage, check the buoyancy status of the main float 12 and the secondary float 11 to ensure that they can automatically adjust their position according to changes in the fuel level, and verify whether the position of the oil suction end 8 is correct to ensure that it can always remain below the fuel level.
