Description

Technical Field

[0001] This application relates to the technical field of hydrogen filling equipment, and in particular to a hydrogen cylinder filling and cooling structure. Background Technology

[0002] Currently, hydrogen is considered a new energy source, and each energy revolution has resulted in a decrease in the carbon content and an increase in the hydrogen content of "carbon-hydrogen energy." Hydrogen is not only a raw material gas for important pillar industries of the national economy such as chemical engineering, oil refining, and metallurgy, but also a source of hydrogen energy. Hydrogen energy mainly refers to the role of hydrogen as an energy source, including the thermal energy generated by hydrogen combustion and the electrical energy generated by hydrogen as a raw material for chemical batteries. The hydrogen used for hydrogen energy has specific requirements for its production methods and quality standards depending on the application scenario.

[0003] Hydrogen cylinders are the most widely used energy storage method, with numerous applications. However, during the filling process, the gas is compressed, causing its temperature to rise. Furthermore, the high-speed flow of gas and friction with pipes, valves, and the cylinder itself also generate heat, leading to a temperature increase of 30-40°C. While outdoor filling can dissipate heat quickly in cooler environments, it can cause the cylinder temperature to rise rapidly, even exceeding 60°C, especially in summer, significantly increasing the safety risks during the filling process. Utility Model Content

[0004] In order to reduce the temperature during the filling process and improve the safety of hydrogen cylinder filling, this application provides a hydrogen cylinder filling cooling structure.

[0005] The technical solution adopted in this application is as follows:

[0006] A hydrogen cylinder filling and cooling structure includes a frame, the frame having a filling space, an mounting component being provided at the upper end of the inner cavity of the frame, and a driving component being provided on the frame for driving the mounting component to move up and down. An atomizing tube is detachably provided on the mounting component, and the atomizing tube is connected to an external water source.

[0007] By adopting the above technical solution, the frame serves as a filling space. The hydrogen cylinder container to be filled is placed within this space, allowing for filling. During the filling process, the atomizing tube is connected to an external water source, spraying atomized water to cool the filling space and reduce the risk of filling. A drive mechanism moves the mounting components up and down, which in turn moves the atomizing tube up and down, adjusting its height and improving adaptability.

[0008] Optionally, a horizontal plate is provided on the frame, and the mounting component includes a sliding rod that slides through the horizontal plate and a connecting rod connecting two adjacent sliding rods. The sliding rods are located at the four corners of the horizontal plate. The driving component is connected to the sliding rods, and a fastener is provided on the connecting rod. The atomizing tube is connected to the connecting rod through the fastener.

[0009] By adopting the above technical solution, the atomizing tube is connected to the connecting rod by fasteners. When the driving component drives the sliding rod to move up and down, it can drive the atomizing tube to move up and down, so as to adjust the height position of the atomizing tube.

[0010] Optionally, the upper end of the frame is provided with a top plate, which is located above the horizontal plate and there is a distance between the top plate and the horizontal plate. The upper end of the sliding rod is located between the top plate and the horizontal plate. A connecting frame is provided between the upper ends of the sliding rods, and the connecting frame connects all the sliding rods. The driving component is connected to the connecting frame.

[0011] By adopting the above technical solution, the driving component can simultaneously drive all the sliding rods to move up and down through the connecting frame.

[0012] Optionally, the sliding rod includes a first rod body that slides through the horizontal plate and a second rod body that slides at the lower end of the first rod body. The first rod body is provided with a locking member for positioning the second rod body. The two ends of the connecting rod are hinged to the side wall of the second rod body, and the length of the connecting rod can be adjusted.

[0013] By adopting the above technical solution, the sliding rod includes a first rod body and a second rod body. The second rod body can slide downwards. Therefore, based on factors such as the temperature distribution in the filling space, the atomizing tube can be adjusted to an inclined state, so as to better adjust the position of the atomizing tube.

[0014] Optionally, the connecting rod includes a first hinge rod and a second hinge rod. The first hinge rod has a slot for the second hinge rod to slide into. The ends of the first hinge rod and the second hinge rod that are far apart from each other are hinged to an adjacent second rod body. The fastener is installed on the first hinge rod and the second hinge rod.

[0015] By adopting the above technical solution, the second hinge rod is slidably inserted into the first hinge rod, thereby allowing the length of the connecting rod to be adjusted. When the second rod moves up and down, the length of the connecting rod can change synchronously.

[0016] Optionally, the fastener includes a buckle ring disposed on the first hinge rod and the second hinge rod, and the buckle ring has a slot for the atomizing tube to be inserted.

[0017] By adopting the above technical solution, the buckle has a locking slot, and the atomizing tube can be inserted into the buckle through the locking slot.

[0018] Optionally, the locking element includes a locking rod threaded to the side wall of the first rod body, the locking rod being able to pass through the first rod body and abut against the side wall of the second rod body.

[0019] By adopting the above technical solution, the locking rod is pressed against the second rod, thereby positioning the second rod.

[0020] Optionally, partitions are provided on three sides of the frame.

[0021] By adopting the above technical solution, the three partitions form the sidewalls of the filling space. During the atomization process, water mist can adhere to the partitions, thereby maintaining the humidity in the filling space and further maintaining the cooling effect.

[0022] In summary, this application includes at least one of the following beneficial effects:

[0023] 1. By installing an atomizing tube at the filling position, the water mist sprayed from the atomizing tube can be cooled quickly, thereby improving the safety of the hydrogen cylinder filling process. The driving component can drive the atomizing tube to adjust its height, so that the atomizing tube can be better adjusted to the appropriate position. Attached Figure Description

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] This application discloses a hydrogen cylinder filling and cooling structure, referring to... Figure 1 The system includes a frame 1, the inner cavity of which forms a filling space 2. One side of the frame 1 is open, and the other three sides are fixed with partitions 12, which form the side walls of the filling space 2. The hydrogen cylinder container to be filled is placed in the filling space 2 for filling.

[0029] Reference Figure 1 and Figure 2 The frame 1 has a top plate 8 and a horizontal plate 6 fixed to its upper end. The top plate 8 is located above the horizontal plate 6, and there is a certain distance between the two plates. A mounting component 3 is slidably mounted on the horizontal plate 6, and a driving component 4 is mounted on the top plate 8. The driving component 4 drives the mounting component 3 to move vertically up and down. The lower end of the mounting component 3 is located in the filling space 2 and is equipped with an atomizing tube 5, which is used to connect to an external water source. During filling, when the temperature rises, the water mist sprayed through the atomizing tube 5 can cool the hydrogen cylinder.

[0030] Reference Figure 1 and Figure 2 The mounting component 3 includes a sliding rod 31 that slides through the horizontal plate 6 and a connecting rod 32 connecting two adjacent sliding rods 31. Four sliding rods 31 are provided, each located at one of the four corners of the horizontal plate 6. Four connecting rods 32 are also provided. The atomizing tube 5 is a loop structure with its ends connected and is mounted on the four connecting rods 32. Fasteners 7 are mounted on the connecting rods 32, and the atomizing tube 5 is mounted on the connecting rods 32 via the fasteners 7. The upper end of the sliding rod 31 is located between the horizontal plate 6 and the top plate 8, and the lower end is located in the filling space 2. The upper ends of the sliding rods 31 are connected together by a connecting frame 9. A driving component 4 is mounted on the top plate 8. The driving component 4 is preferably an electric telescopic rod, and the driving component 4 is connected to the center of the connecting frame 9. By driving the connecting frame 9 to move up and down, the sliding rods 31 can be driven to move up and down. In other embodiments, the driving component 4 can also be a cylinder or a screw driven by a motor, with the screw and the connecting frame 9 threaded together. Any device capable of driving the connecting frame 9 to move up and down is acceptable.

[0031] The sliding rod 31 includes a first rod 311 that slides through the horizontal plate 6 and a second rod 312 that slides at the lower end of the first rod 311. The first rod 311 has an internal hollow structure and extends to the lower end of the first rod 311. The second rod 312 is slidably inserted into the first rod 311. A locking member 10 is provided on the side wall of the first rod 311, which is used to position the second rod 312. The locking member 10 is a locking rod threaded to the side wall of the first rod 311 and can abut against the side wall of the second rod 312. The connecting rod 32 includes a first hinge rod 321 and a second hinge rod 322. A slot 11 is provided on the first hinge rod 321, and one end of the second hinge rod 322 is slidably inserted into the first hinge rod 321. The ends of the first hinge rod 321 and the second hinge rod 322 that are far apart from each other are hinged to the side wall of the second rod 312. The fastener 7 includes multiple retaining rings 71 fixed to the first hinge rod 321. Each retaining ring 71 has a locking slot and is made of an engineering plastic material with a certain degree of elasticity, allowing the atomizing tube 5 to be inserted into the retaining ring 71. The atomizing tube 5 is interference-fitted into the retaining ring 71, thereby allowing the orientation of the nozzle on the atomizing tube 5 to be adjusted by rotating the atomizing tube 5.

[0032] By sliding two of the second rods 312 downwards, the first hinge rod 321 and the second hinge rod 322 slide relative to each other, thereby allowing the atomizing tube 5 to be adjusted to a state of tilting from bottom to top, thus allowing the atomizing tube 5 to be adjusted to a state of better cooling effect.

[0033] The implementation principle of the hydrogen cylinder filling and cooling structure in this application embodiment is as follows: During filling, if the temperature in the filling space 2 is higher than the predetermined temperature, the water source of the atomizing tube 5 is activated to cool the filling space 2. The driving component 4 can drive the atomizing tube 5 to move up and down, thereby adjusting the height position of the atomizing tube 5 and thus improving the cooling effect.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
