Technical Field

[0001] The invention relates to a ship fuel tank TCS cabin, in particular to a ship fuel tank TCS cabin installation structure. Background Art

[0002] The ship fuel tank TCS tank is an important part in shipbuilding, involving complex installation structure and functional design. The installation structure of the ship fuel tank TCS tank includes a fuel tank. In terms of function, the fuel tank TCS tank is part of the LNG fuel supply system and is used to store liquid LNG fuel.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention installs eight energy-absorbing rubber airbags, so that when the ship shakes and drives the ship's fuel tank body to shake, the ship's fuel tank body squeezes the energy-absorbing rubber airbag, so that the energy-absorbing rubber airbag is compressed, thereby increasing the air pressure inside the energy-absorbing rubber airbag, and then pressing the dry air inside the energy-absorbing rubber airbag into the inside of the externally connected air box, so that the air pressure inside the externally connected air box is increased, so that the dry air inside the externally connected air box is passed into the interior of the present invention through the air transmission pipeline, the dry annular pipe and the air outlet pipe, and the air can be blown to the upper end of the ship's fuel tank body to keep the ship's fuel tank body dry, so that the dry air replaces the humid air inside the present invention, and the air inside the present invention flows, so as to prevent the internal components of the present invention from being rusted, thereby extending the service life of the internal components of the present invention and improving the practicality of the present invention;

[0019] 2. The present invention can install an air pressure plate, and when the ship fuel tank body is installed on the ship, the ship fuel tank body will press down the limit spring 2 and the silicone adsorption support platform under the action of gravity, so that the silicone adsorption support platform pushes the pressing bracket downward, so that the pressing bracket pushes down the air pressure plate, and then the air pressure plate compresses the air inside the base, so that the air pushes the rubber anti-rust shielding plate out of the present invention through the air groove, so that the rubber anti-rust shielding plate covers the upper end of the installation connecting plate, avoiding the fastening screws inside the installation connecting plate from contacting with the outside air, preventing the fastening screws from being rusted, and at the same time, the rubber anti-rust shielding plate blocks the upper end of the fastening screws, which can limit the fastening screws and prevent the fastening screws from spinning, thereby ensuring the stability of the installation structure of the present invention;

[0020] 3. The present invention can dehumidify the air entering the present invention through the air intake duct by installing a moisture absorption layer, thereby ensuring the dryness of the interior of the present invention; installing an air intake check valve can prevent the air inside the energy absorbing rubber airbag from being discharged from the present invention through the air intake duct when the energy absorbing rubber airbag is compressed, thereby ensuring that dry air can enter the present invention only after being absorbed by the moisture absorption layer, thereby ensuring that the air inside the energy absorbing rubber airbag is discharged along a designated path;

[0021] 4. The present invention can adsorb the lower end of the ship fuel tank body by installing a silica gel adsorption support platform. The silica gel adsorption support platform cooperates with the limit spring 2 to play the role of energy absorption and buffering, thereby preventing the vertical shaking amplitude of the ship fuel tank body from being too large;

[0022] 5. The present invention can play the role of transferring dry air by installing an external connecting air box, so that the dry air in the eight energy-absorbing rubber airbags can be merged, ensuring the stability of the air outlet of several air outlet pipes. The installation of the air outlet check valve can ensure that the air can only be discharged from the air outlet pipe, and the external humid air cannot enter the air outlet pipe into the internal part of the external connecting air box, ensuring the complete functionality of the present invention;

[0023] 6. The present invention installs a support spring to play a supporting and auxiliary deformation role, so that the energy-absorbing rubber airbag can be restored when it is not squeezed by external force. BRIEF DESCRIPTION OF THE DRAWINGS

The three external connecting air boxes 17 are fixedly connected to the energy-absorbing rubber airbag 10. The installation of the external connecting air box 17 can play the role of transferring dry air, so that the dry air in the eight energy-absorbing rubber airbags 10 can be merged, ensuring the stability of the gas outlet of several outlet pipes 23, and the three external connecting air boxes 1 7 are fixedly installed with connecting air pipes 18 between adjacent ones, and a gas pipeline 19 is fixedly installed at the lower end of the external connecting air box 17, and a drying annular pipe 22 is fixedly installed at one end of the gas pipeline 19, and an air outlet pipe 23 is fixedly installed at the upper and lower ends of the drying annular pipe 22, and an air outlet check valve 24 is fixedly installed on the outside of the air outlet pipe 23.

[0037] A breathable mesh box 13 is fixedly installed at the upper end between the mounting structure main body 1 and the mounting inner tube 15. A hygroscopic layer 14 is arranged inside the breathable mesh box 13. The hygroscopic layer 14 can dehumidify the air entering the interior of the present invention through the air intake pipe 3 to ensure the dryness of the interior of the present invention. There are six air intake pipes 3 in the upper end annular array outside the mounting structure main body 1. The outsides of the six air intake pipes 3 are all fixedly installed with an air intake check valve 4.

[0038] The limiting spring 230 is arranged in a circular array at the upper end of the base 5. The upper end of the limiting spring 230 is fixedly installed with a silicone adsorption support platform 26. A downward pressing bracket 27 is arranged inside the limiting spring 230.

At the same time, the rubber anti-rust baffle plate 7 blocks the upper end of the fastening screws 8, and can also limit the fastening screws 8 to prevent the fastening screws 8 from spinning, thereby ensuring the stability of the installation structure of the present invention. The air pressure plate 29 is connected to the base 5 by sliding up and down through a slot. The base 5 is provided with an air groove 20, and the rubber anti-rust baffle plate 7 is installed inside the outer side of the base 5 through the slot.

[0039] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 and Fig. 9 A support spring 21 is installed inside the energy-absorbing rubber airbag 10. Installing the support spring 21 can enable the energy-absorbing rubber airbag 10 to recover when it is not squeezed by external force. The support spring 21 plays a role of supporting and assisting deformation. The support spring 21 is fixedly connected to the energy-absorbing rubber airbag 10. There are six mounting connecting plates 6 in a circular array at the lower end of the outside of the base 5. The six mounting connecting plates 6 are welded to the base 5, and fastening screws 8 are installed inside the mounting connecting plates 6.

[0040] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Fig.10 A sealing plate 2 is installed at the upper end between the mounting structure main body 1 and the mounting inner cylinder 15, and the sealing plate 2 is fixedly connected to the mounting structure main body 1 and the mounting inner cylinder 15. A top limiting bracket 25 is installed at the upper end of the sealing plate 2. The installation of the top limiting bracket 25 can limit the upper end of the ship fuel tank main body 9 to prevent the ship fuel tank main body 9 from having excessive longitudinal movement, ensuring that the ship fuel tank main body 9 is always installed inside the present invention, and ensuring the functional integrity of the present invention. The top limiting bracket 25 is connected to the sealing plate 2 by screws. A contact plate 11 is installed on the side of the energy-absorbing rubber airbag 10 away from the mounting inner cylinder 15, and the contact plate 11 is fixedly connected to the energy-absorbing rubber airbag 10.

The upper end annular array outside the mounting inner cylinder 15 has six connecting pipes 16, and the connecting pipe 16 is fixedly connected to the mounting inner cylinder 15.

[0041] Working principle: When in use, the ship fuel tank body 9 is installed inside the present invention, so that the lower end of the ship fuel tank body 9 is adsorbed by the silica gel adsorption support platform 26. When the ship fuel tank body 9 is installed inside the present invention, the ship fuel tank body 9 presses the silica gel adsorption support platform 26 and the downward pressing bracket 27 downward, so that the limit spring 230 is compressed, and at the same time, the downward pressing bracket 27 pushes the air pressure plate 29 downward, so that the air pressure inside the base 5 increases, so that the air pushes the rubber anti-rust shielding plate 7 to move through the air groove 20, and then the rubber anti-rust shielding plate 7 extends out of the base 5, so that the rubber anti-rust shielding plate 7 is installed on the upper end of the connecting plate 6. The screws 8 are tightened for protective shielding, and then the top limit bracket 25 is connected to the sealing plate 2 with screws, so that the top limit bracket 25 limits the maximum longitudinal travel of the ship fuel tank body 9. When the ship is traveling on the sea and is shaken by the weather, the shaking will be transmitted to the ship fuel tank body 9, and the ship fuel tank body 9 will shake inside the present invention, so that the ship fuel tank body 9 will continuously squeeze the energy absorbing rubber airbag 10, so that the energy absorbing rubber airbag 10 is compressed, and then the air pressure inside the energy absorbing rubber airbag 10 is increased, and the dry air inside the energy absorbing rubber airbag 10 is pressed into the external connecting air box 17. The air pressure inside the externally connected air box 17 is increased, and the dry air inside the externally connected air box 17 is passed into the interior of the present invention through the air delivery pipeline 19, the drying annular pipe 22 and the air outlet pipe 23, so that the air can be blown to the outside of the ship fuel tank body 9, so that the ship fuel tank body 9 is kept dry, thereby replacing the moist air inside the present invention with dry air, allowing the air inside the present invention to flow, preventing the internal components of the present invention from being rusted, thereby extending the service life of the internal components of the present invention; when the ship fuel tank body 9 stops squeezing the energy absorbing rubber airbag 10, the good recovery ability of the energy absorbing rubber airbag 10 itself cooperates with The support spring 21 allows the energy-absorbing rubber airbag 10 to recover quickly. During the recovery process of the energy-absorbing rubber airbag 10, a certain suction force will be generated, which reduces the air pressure inside the energy-absorbing rubber airbag 10. Since the air outlet check valve 24 is installed outside the air outlet pipe 23, the air cannot enter the energy-absorbing rubber airbag 10 through the air outlet pipe 23, and can only enter the interior of the present invention through the air pipeline 19. When the air enters the interior of the present invention through the air pipeline 19, it can be dehumidified under the action of the moisture absorption layer 14, and then the dry air enters the energy-absorbing rubber airbag 10 through the connecting pipe 16, so that the internal air pressure of the energy-absorbing rubber airbag 10 is balanced with the external air pressure. When the present invention is used, no additional power source is required, and its own function can be realized by relying on the shaking of the ship itself, which greatly reduces energy consumption, thereby reducing the cost of use.

[0042] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
