[0020] The following is a further detailed description of the specific implementation methods of the present invention by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate its implementation.

[0021] like Figure 1 and Figure 2 As shown, the water curtain protection pipe of the side outer plate of the LNG filling station includes a deck, a fixed support 2 is provided on the deck, a movable support 4 is provided on the fixed support 2, the middle part of the movable support 4 is detachably connected to the fixed support 2, the bottom end of the movable support 4 is movably connected to the fixed support 2, and the water curtain protection pipe 1 is provided on the top of the movable support 4.

[0022] In the above structure, the fixed support 2 is used to install the movable support 4, so that the water curtain protection tube 1 is at a certain height. The water curtain protection tube 1 is installed on the movable support 4, and it can change its posture as the movable support 4 moves, adapting to the two usage requirements of pipeline storage and water curtain protection.

[0023] like Figure 1 As shown, the movable support 4 is connected to the top of the fixed support 2 with a fixing bolt 6; the bottom of the movable support 4 is connected to the side of the fixed support 2 with a tilting shaft 7. The movable support 4 is hinged to the fixed support 2 via the tilting shaft 7. The fixing bolt 6 can be removed or installed, corresponding to the use and storage of the water curtain protection tube 1. The tilting shaft 7 forms a hinged connection at the bottom of the movable support 4, providing the movable support 4 with a rotation function. The tilting shaft 7 can also be replaced by a bolt, and the fixing bolt 6 can also be replaced by a clamping structure or a pin.

[0024] like Figure 1 and Figure 2 As shown, the dotted line in the figure is the state after the water curtain protection tube is tilted. A limit support 3 is provided on the fixed support 2, and the upper end surface of the limit support 3 is set horizontally. The limit support 3 is used to support the movable support 4 after tilting, ensuring that the water curtain protection tube 1 is in a stable posture when in use. The length of the movable support 4 is greater than the distance from the side outer plate to the fixed support 2. The side outer plate is provided on the outside of the deck end, and the fixed support 2 is located on the inside of the side outer plate. When the water curtain protection tube 1 is in use, it is rotated 90° until the movable support 4 abuts against the limit support 3. At this time, the movable support 4 is in a horizontal posture, and the line connecting the opening 8 and the central axis of the water curtain protection tube 1 is 30° to the outer wall of the side outer plate. The opening 8 of the water curtain protection tube 1 can be located on the outside of the side outer plate. At this time, the opening 8 faces the side outer plate to form a water curtain protection.

[0025] like Figure 1 and Figure 2 As shown, U-shaped pipe clamps 5 are provided at both ends of the water curtain protection tube 1, and the ends of the U-shaped pipe clamps 5 are fixed to the movable support 4 by bolts. The contact portion between the U-shaped pipe clamps 5 and the water curtain protection tube 1 has a smooth transition, which has little effect on the squeezing and deformation of the water curtain protection tube 1. It also occupies a small space and does not block the branch pipe 9 or the opening 8. It can be fixed and stabilized by simply installing it at both ends of the water curtain protection tube 1.

[0026] like Figure 2As shown, a branch pipe 9 is provided at one end of the water curtain protection pipe 1, and a fire hydrant is connected to the branch pipe 9. The fire hydrant is connected to the branch pipe 9 through a flange, and a hose is used to connect the fire water.

[0027] like Figure 2 As shown, sealing plates are provided at both ends of the water curtain protection tube 1, and openings 8 are evenly distributed on the water curtain protection tube 1. The sealing plates seal the outlet areas at both ends of the water curtain protection tube 1, allowing the openings 8 to serve as water outlets. The even distribution of the openings 8 can improve the water curtain protection effect.

[0028] like Figure 1 As shown, the movable support 4, fixed support 2, and limit support 3 are all angle steel structures. These structures are made of commonly used profiles, resulting in low production costs. The angle steel supports offer reliable performance and are not prone to deformation. The angle steel features two perpendicular flat surfaces, facilitating the installation of the tilting shaft 7, fixing bolts 6, and U-shaped pipe clamps. The limit support 3 is quickly welded to the fixed support 2, ensuring its upper end surface is horizontal without requiring any measurements.

[0029] like Figure 1 and Figure 2 As shown, a support 10 and a liquid accumulation tray are also provided on the deck. An LNG filling pipe is provided on the support 10, and the LNG filling pipes are arranged in pairs.

[0030] The water curtain protection tube 1 is installed as follows: the fixed support 2 is welded to the hull deck, holes are opened on the fixed support 2 and the movable support 4 for installing the fixing bolts 6 and the tilting shaft 7, the movable support 4 is installed to the fixed support 2 using the fixing bolts 6 and the tilting shaft 7, the limiting support 3 is welded to the fixed support 2, and the water curtain protection tube 1 is installed on the movable support 4 with a U-shaped pipe clamp 5.

[0031] When the water curtain protection tube 1 is in use, it can be operated on board. Loosen the fixing bolts 6, and the movable support 4 rotates around the tilting axis 7 due to gravity until the movable support 4 contacts the limit support 3. The working state is stable and reliable. At this time, the movable support 4 is horizontal, and the opening 8 on the water curtain protection tube 1 is in the proper position. Connect the fire water hose to the fire hydrant to form a water curtain protection. When the water curtain protection tube 1 is not in use, it is fixed to the fixed support 2 using the fixing bolts 6. On board, it does not extend beyond the ship's width, making it less susceptible to collision damage and loss, and also convenient for maintenance and replacement.

[0032] This LNG filling station features a water curtain protective tube on the side panel, featuring a rational connection structure. Unlike traditional fixed or hook-type structures, the water curtain protective tube 1 is mounted on a movable support 4, making it easy to store and prevent loss. Supported by a limit support 3, it maintains a stable posture and high safety. The movable support 4 is detachable at one end and hinged at the other, preventing the water curtain protective tube 1 from extending beyond the ship's beam when not in use, eliminating the risk of collision damage and facilitating maintenance and replacement. The support structure features a simple design, easy and safe operation, and is made of commonly available materials, resulting in low manufacturing costs.
