Technical Field
[0001] The utility model relates to the field of hydrogen fuel, in particular to a hydrogen fuel ship supply device. Background Art
[0002] A hydrogen-fueled ship is a vessel that uses hydrogen fuel cells as its power source. This type of ship uses hydrogen and oxygen to produce electricity through a chemical reaction in the fuel cell, thereby driving the ship forward. The advantages of hydrogen-fueled ships include high efficiency, zero emissions, and renewability, making them very suitable for the green and low-carbon development needs of inland waterway shipping. Fuel cells have attracted much attention as a long-term fixed power generation device. Fuel cells can generate electricity for a long time because they use hydrogen. Large amounts of hydrogen are generally supplied by multiple hydrogen cylinders in parallel. In existing hydrogen fuel supply devices, after the hydrogen cylinders are used up, they are usually refilled or replaced. The process of replacing the hydrogen cylinders involves fixing the hydrogen cylinders. However, existing hydrogen cylinders are mostly fixed with bolts and can only fix hydrogen cylinders of the same specifications, which has poor flexibility and limits the use of hydrogen cylinders.

However, its threaded rotating rods are respectively arranged on both sides of the movable plate. The threaded rotating rods on both sides need to be rotated synchronously, which increases the difficulty of operation and is not convenient to use. Utility Model Content

[0023] The utility model is described in further detail below:
[0024] like Figures 1 to 5 As shown, the utility model provides a hydrogen fuel ship supply device, including a mounting box 1 and a hydrogen tank 2. The interior of the mounting box 1 is fixedly installed with fixing components 3 at equal intervals in the longitudinal direction. The hydrogen tank 2 is movably installed inside the fixing component 3. A supply pipeline 4 is fixedly installed at the rear of the interior of the mounting box 1.
[0025] The fixing assembly 3 includes a mounting frame 31, and the interior of the mounting frame 31 is provided with mounting grooves 32 that pass through the front and back at equal intervals. The hydrogen tank 2 is movably connected to the interior of the mounting groove 32. A limiting groove 33 is provided inside the mounting frame 31. Two rotating shafts 34 are rotatably installed on the upper and lower sides of the limiting groove 33. A rotating shaft 2 35 is rotatably installed on the left side of the interior of the mounting frame 31. The outside of the two rotating shafts 1 34 is provided with bidirectional threads 36 corresponding to the positions of the mounting grooves 32. The ends of one of the rotating shafts 1 34 and the rotating shaft 2 35 are fixedly installed with mutually meshing transmission gears 37, and the external threads of the bidirectional threads 36 are connected to the clamping blocks 38 arranged on the left and right sides of the mounting groove 32.
[0026] The hydrogen tank 2 is set inside the installation groove 32, and the transmission gear 37 between the second rotation shaft 35 and the first rotation shaft 34 drives the rotation shaft 1 34 to rotate. The bidirectional thread 36 corresponding to the position of the installation groove 32 and in the opposite direction is set on the outside of the rotation shaft 1 34 to drive the clamping block 38 to move in opposite directions along the bidirectional thread 36 to clamp and fix the hydrogen tank 2 in the installation groove 32 from the side. Multiple hydrogen tanks 2 can be fixed or released by simply operating the second rotation shaft 35. The operation is simple and easy to use.
[0027] like Figure 5 As shown, the installation box 1 includes an outer shell 11 and a sealed door body 12 and a sealed door body 2 13 movably hinged on the front and rear sides of the outer shell 11. The interior of the outer shell 11 is fixedly connected with an inner interlayer 14. An insulating cavity 15 is provided between the outer shell 11 and the inner interlayer 14. The interiors of the sealed door body 12 and the sealed door body 2 13 are both provided with an insulating cavity 2 16.
[0028] An insulating cavity 15 is set between the outer shell 11 and the inner interlayer 14, and an insulating cavity 2 16 is set inside the sealed door body 12 and the sealed door body 2 13. The insulating cavity 15 and the insulating cavity 2 are connected to the outside through interfaces to evacuate the inside, so as to isolate the hydrogen tank 2 located in the inner interlayer 14. It not only has good insulation and sealing performance, but also reduces the impact of the external temperature increase on the hydrogen tank 2, and has higher safety and stability.
[0029] The sealed door body 12 and the sealed door body 2 13 both adopt a double-layer structure design corresponding to the outer shell 11 and the inner interlayer 14. The inner layer is made of metal material and the outer layer is made of insulating material to improve their sealing performance and heat insulation effect. The sealed door body 12 and the sealed door body 2 13 are connected to the outer shell 11 through a precise hinge mechanism to ensure that the door body is smooth and noiseless during the opening and closing process.
[0030] like Figure 4 As shown, a synchronous wheel 39 is fixedly mounted on the outside of the two rotating shafts 35 away from one end of the rotating shaft 35 , and a synchronous toothed belt 310 is movably mounted on the outside of the synchronous wheel 39 .
[0031] By arranging the synchronous wheels 39 and the synchronous toothed belt 310 outside the two second rotating shafts 35 , it is possible to ensure that the synchronous transmission drives the two second rotating shafts 35 to rotate synchronously to ensure the synchronous stability of the clamping block 38 .
[0032] like Figure 4 As shown, the inner side of the clamping block 38 is arranged in an arc shape, and the upper and lower sides of the clamping block 38 are respectively threadedly connected to the outer sides of the two bidirectional threads 36 on the outer sides of the two rotating shafts 34.
[0033] The clamping block 38 is movably engaged with the interior of the limiting groove 33 .
[0034] The inner side of the clamping block 38 is arc-shaped and adapted to the outer shell of the hydrogen tank 2 for clamping and stabilizing. The clamping block 38 is threadedly connected to the outside of the two-way thread 36, and the two-way thread 36 is symmetrically arranged on the left and right sides of the installation groove 32 to ensure the synchronization of the clamping block 38. The setting of the limit groove 33 is used to cooperate with the clamping block 38 to limit the clamping block 38. When the clamping block 38 moves in the limit groove 33, the position of the clamping block 38 is precisely controlled.
[0035] like Figure 4 As shown, rubber pads are provided inside the mounting groove 32 and the clamping block 38 .
[0036] The rubber cushion layer contacts the hydrogen tank 2 to play a buffering and rebounding role, thereby improving safety performance.
[0037] like Figure 1 As shown, a monitoring mechanism 5 is fixedly installed on the top of the inner side of the inner interlayer 14 .
[0038] The monitoring mechanism 5 uses a gas sensor and a temperature sensor to monitor the situation inside the inner interlayer 14 to improve safety.
[0039] like Figure 5 As shown, the insulation chamber 1 15 and the insulation chamber 2 16 are vacuumed.
[0040] The interior of the insulation chamber 15 and the insulation chamber 2 16 is evacuated to improve the insulation performance by utilizing the vacuum insulation effect, thereby reducing the impact of the high external temperature on the hydrogen tank 2.
[0041] The following is a detailed description of the working principle of the hydrogen fuel ship supply device.
[0042] like Figures 1 to 5As shown, the hydrogen tank 2 is pushed into the mounting groove 32 corresponding to the interior of the mounting frame 31, and then the rotating handle at the end of the rotating shaft 2 35 located on the front side of the mounting frame 31 is rotated to drive the rotating shaft 2 35 to rotate. Since the rear end of the rotating shaft 2 35 and the left end of the rotating shaft 1 34 are fixedly installed with a transmission gear 37 that meshes with each other to drive the matching rotating shaft 1 34 to rotate, the other ends of the two rotating shafts 1 34 are installed with a synchronous wheel 39 to drive the synchronous toothed belt 310 to drive the two rotating shafts 1 34 to rotate synchronously. Since the external part of the rotating shaft 1 34 is provided with a bidirectional thread 36 corresponding to the position of the mounting groove 32 and in the opposite direction, and the clamping block 38 is threadedly connected to the external part of the bidirectional thread 36 symmetrical on the left and right, when the rotating shaft 1 34 rotates, the clamping block 38 is driven to be fixed in the limit groove 33 The internal clamping blocks 38 move toward or away from each other along the bidirectional threads 36, and the hydrogen tank 2 located in the mounting groove 32 is clamped and fixed from the side by the approach of the clamping blocks 38, and the clamping of the hydrogen tank 2 is released by the mutual distance of the clamping blocks 38, so that the hydrogen tank 2 can be easily disassembled. After the hydrogen tank 2 is installed and fixed, it is docked with the supply pipeline 4, and the supply pipeline 4 is docked with the external pipeline and a valve is set to control the supply and transportation of hydrogen in the hydrogen tank 2. It is installed inside the mounting box 1 through the fixing component 3, and an insulating cavity 15 is set between the outer shell 11 and the inner interlayer 14, and an insulating cavity 2 16 is set in the sealing door body 12 and the sealing door body 2 13. A vacuum is set in the insulating cavity 15 and the insulating cavity 2 16 to improve the temperature insulation effect.
[0043] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
