DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to make the technical means, creative features, achieved purposes, and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] As shown Figure 1 in the figure, the utility model provides a safety management device for a hydrogen fuel ship, including a tank body 4.

A protection component 2 is arranged above the outer surface of the tank body 4. Support seats 3 are fixedly connected to the left and right sides below the outer surface of the tank body 4. Mounting seats 1 are fixedly connected to the lower surfaces of the left and right support seats 3. Mounting blocks are fixedly connected to the middle parts below the left and right sides of the mounting seats 1. A vertically through mounting hole is formed in the middle of the upper surface of the mounting block;

[0026] Through the arrangement of the pipes and valves on the left and right sides of the tank body 4, it is convenient to use the liquid hydrogen fuel or transport the liquid hydrogen fuel into the tank body 4. Through the arrangement of the protection component 2, it is convenient to protect the outer surface of the tank body 4, preventing the phenomenon that the objects in the ship collide with it due to the shaking of the ship in windy and wavy weather, thus improving the safety.

[0027] As shown Figure 2 in the figure, two connection components 41 are arranged in a mirror image on the left and right sides inside the tank body 4. Guide rods 42 are fixedly connected to the middle parts of the opposite surfaces of the two connection components 41. Sleeves 44 are slidably connected to the outer surfaces of the left and right guide rods 42. Springs 43 are arranged inside the sleeves 44. The left and right ends of the springs 43 are fixedly connected to the surfaces of the left and right guide rods 42. T-shaped metal blocks 45 and strip plates are fixedly connected to the lower parts of the inner walls of the connection components 41. Grooves 46 are formed in the horizontal directions of the T-shaped metal blocks 45 and the middle parts of the opposite surfaces of the strip plates. Chute grooves 47 are formed in the front and rear sides of the strip plates and the front and rear sides in the horizontal directions of the T-shaped metal blocks 45. The outer surfaces in the vertical directions of the T-shaped metal blocks 45 penetrate through the outside of the tank body 4 and are fixedly connected to each other. The left and right sides in the vertical directions of the T-shaped metal blocks 45 are lapped with the opposite surfaces of the left and right support seats 3;

[0028] Through the arrangement of the connection components 41, the internal space of the tank body 4 is divided into several areas, reducing the impact force of the liquid hydrogen fuel colliding with the tank body 4. Through the arrangement of the springs 43, it is convenient to move the left and right connection components 41 and has buffering. Through the grooves 46, the positions of the left and right connection components 41 are restricted, preventing the separation of the guide rods 42 from the sleeves. At the same time, the arrangement of the T-shaped metal blocks 45 is convenient for conducting the static electricity generated during collisions.

[0029] As shown Figure 3As shown in the figure, both of the two connecting components 41 include a first protective plate 411. T-shaped grooves 412 that communicate left and right are formed in the upper and lower sides on the left of the first protective plate 411. The inner walls in the vertical direction of the T-shaped grooves 412 communicate inside and outside. The outer surface in the vertical direction of the T-shaped grooves 412 is slidably connected to the inside of the chute 47. A connecting column 413 is fixedly connected to the middle of the left side of the first protective plate 411. One end of the connecting column 413 away from the first protective plate 411 is fixedly connected to a second protective plate 414. Bar-shaped openings that communicate left and right are formed in the upper and lower sides on the left of the second protective plate 414. The connecting components 41, the guide rods 42, and the sleeves 44 are made of antistatic nylon material;

[0030] The setting of the T-shaped grooves 412 in the first protective plate 411 facilitates sliding inside the chute 47 in the strip plate and the T-shaped metal block. The setting of the bar-shaped openings in the second protective plate 414 facilitates the flow of liquid hydrogen fuel. Moreover, a flow port is formed between the outer surface of the first protective plate 411 and the inner wall of the tank body 4, facilitating the flow of liquid hydrogen fuel.

[0031] As Figure 4 As shown in the figure, the protection component 2 includes an arc-shaped protective housing 21. An arc-shaped rubber pad 22 is fixedly connected to the inside of the arc-shaped protective housing 21. The inside of the arc-shaped rubber pad 22 is lapped with the outer surface of the tank body 4. Fixing plates 23 are fixedly connected to the front, rear, left, and right sides of the outer surface of the arc-shaped protective housing 21. Trapezoidal grooves are formed in the fronts of the fixing plates 23. A plug-in groove is formed in the middle of the lower surface of the fixing plates 23. The front and rear fixing plates 23 are arranged in a mirror image. A positioning rubber 24 is inserted into the inside of the plug-in groove. The rear side of the positioning rubber 24 is fixedly connected to the surface of the support seat 3. A square block 25 is arranged inside the positioning rubber 24. An installation groove 241 is formed in the upper part of the front of the positioning rubber 24. The upper and lower sides and the left and right sides of the inner wall of the installation groove 241 are movably connected to the upper and lower surfaces of the square block 25. The lower surface of the square block 25 is lapped with the upper surface of the inner wall of the trapezoidal groove in the fixing plate 23. Two inclined surfaces 242 are arranged in a mirror image on the left and right sides of the outer surface of the positioning rubber 24. The positioning rubber 24 is in a contracted state;

[0032] The setting of the arc-shaped protective housing 21 facilitates the protection of the tank body 4, preventing external objects from hitting the tank body 4. At the same time, the setting of the arc-shaped rubber pad 22 provides buffer protection during impact, ensuring the safety performance of the tank body 4. After the arc-shaped protective housing 21 covers and contacts the outer surface of the tank body 4, the plug-in groove in the fixing plate 23 squeezes and contracts the positioning rubber 24, causing it to deform. When it moves to an appropriate position, the square block 25 on the left and right is rotated to make the square block contact the lower surface of the inner wall of the trapezoidal groove in the fixing plate 23, thus realizing the rapid installation of the arc-shaped protective housing 21. The setting of the inclined surfaces 242 facilitates the plug-in groove to better squeeze and contract the positioning rubber 24.

[0033] The working principle of the hydrogen fuel ship safety management device will be specifically described below.

[0034] Through the setting of the connecting component 41, the internal space of the tank body 4 is divided into several areas, reducing the impact force of the liquid hydrogen fuel colliding with the tank body 4. Through the setting of the spring 43, it is convenient to move the left and right connecting components 41 and has buffering. Through the setting of the arc-shaped protective cover 21, it is convenient to protect the tank body 4, preventing external objects from hitting the tank body 4, and ensuring the safety performance of the tank body 4. After the arc-shaped protective cover 21 covers the outer surface of the tank body 4 and makes contact, the insertion slot in the fixed plate 23 is squeezed and shrunk and deformed with the positioning rubber 24. When it moves to an appropriate position, then by rotating the squares 25 on the left and right, the squares contact the lower surface of the inner wall of the trapezoidal groove in the fixed plate 23, thus realizing the rapid installation of the arc-shaped protective cover 21.

[0035] The above has generally described the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, the modifications or improvements made without departing from the spirit of the present invention are all within the protection scope of the present invention.
