Description

Technical Field

[0001] This utility model relates to the field of fuel tank technology, specifically to a solid hydrogen storage fuel tank that can be used at any angle. Background Technology

[0002] Currently, there are many designs for the interfaces of hydrogen fuel tanks in solid hydrogen storage devices. The two main types are: One is a chuck-like structure, integrating an aluminum chuck opening mechanism at the tank opening with a sealing gasket inside. Sealing and connection are achieved by tightening bolts. This method achieves a seal and meets basic hydrogen supply requirements. However, due to the chuck-like design at the tank opening, the opening structure is larger, more expensive, and the opening can only be designed for radial output, making it unsuitable for scenarios with lateral layouts and quick-connect requirements. The other type is press-fit connection. The sheet metal of the tank opening and the fuel tank body are edge-sealed and press-fitted together using molds or tooling. This method achieves sealing and connection, but the structure is complex and requires additional tooling and mold design. Furthermore, because it uses a press-fit method, the product is a one-piece molding, which is not conducive to repeated replacement and maintenance later on. Utility Model Content

Detailed Implementation

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0021] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0022] like Figure 1-2As shown, this embodiment provides a solid hydrogen storage fuel tank that can be used at any angle for storing hydrogen, and the stored hydrogen also needs to be easily accessible. Most fuel tanks are elongated and can stand upright or lie flat. In different postures, it is necessary to ensure that the hydrogen can be smoothly released from the tank body 100. The solid hydrogen storage fuel tank in this embodiment includes a tank body 100, an interface assembly, and a gas pipe 500. An installation structure is provided at the tank opening 110 of the tank body 100, and the interface assembly is connected to the tank opening 110 through the installation structure. The interface assembly specifically includes a base 200, an output connector 300, and an input connector 400. The base 200 is sealed to the tank opening 110 to prevent hydrogen escape from the tank body 100. The output connector 300 and the input connector 400 are spaced apart on the base 200 and are respectively connected to the interior of the tank body 100. The output connector 300 is mainly used for accessing hydrogen; that is, hydrogen is released from the output connector 300 during use, and the device that needs to access hydrogen is connected to the output connector 300. The input connector 400 is used to fill the tank 100 with hydrogen. When the hydrogen in the tank 100 is depleted, it can be replenished through the input connector 400. The gas pipe 500 is connected to the output connector 300 and is used to discharge the hydrogen from the tank 100. The gas pipe 500 includes a first pipe section 510 and a second pipe section 530. The first pipe section 510 is connected to the base 200, and the second pipe section 530 is closer to the inner wall of the tank 100 than the first pipe section. A nut 501 is also connected to the part of the first pipe section 510 that connects to the base 200 to increase the stability of the gas pipe 500. The second pipe section 530 ensures that hydrogen can still be collected when the tank 100 is horizontally placed. When the tank 100 is horizontally placed, hydrogen will accumulate on the upper side of the tank 100. At this time, the second pipe section 530 near the side can directly discharge the accumulated hydrogen. It should be noted that when the pipe is placed horizontally, it is necessary to ensure that the inner wall of the second pipe section 530 is on top.

[0023] The above solution has the following effects: the interface components are easy to install and disassemble, and the design of the gas pipe 500 close to the inner wall allows for smooth output of hydrogen even when the tank 100 is placed horizontally.

[0024] In some embodiments, the mounting structure is internally threaded, and the base 200 is screwed to the can opening 110 via the internal thread. The threaded connection allows for quick disassembly and installation of the base 200, and the threaded connection offers high strength, ensuring a secure and reliable connection of the base 200. The input connector 400 and the output connector 300 are also connected to the base 200 via threaded structures. The output connector and the air pipe 500 are located on the same straight line; that is, the central axis of the output connector 300 coincides with the central axis of the air pipe 500.

[0025] In some embodiments, the first pipe segment 510 and the second pipe segment 530 are approximately the same length. Since the opening 110 of the tank 100 gradually narrows, causing the opening 110 to be located at the centerline of the tank 100, the first pipe segment 510 extends into the tank 100 at the centerline of the tank 100. A transition section 520 is provided between the second pipe segment 530 and the first pipe segment 510. The transition section 520 extends upward and backward at an angle from the end of the first pipe segment 510, while the second pipe segment 530 extends horizontally along the end of the transition section 520 away from the first pipe segment 510. The junctions between the transition section 520 and both the first and second pipe segments 510 are rounded.

[0026] In some embodiments, a filter screen is also provided on the second pipe section 530. The filter screen is used to prevent the hydrogen storage material from clogging the inlet or channel of the second pipe section 530. The filter screen is directly sleeved on the outer periphery of the second pipe section 530.

[0027] In some embodiments, the base 200 includes an inner section 210 and an outer section. The outer periphery of the inner section 210 is provided with an external thread that matches the internal thread. The outer end face of the outer section is provided with a first interface 201 for mounting an output connector 300 and a second interface 202 for mounting an input connector 400. The diameter of the outer section is larger than that of the inner section 210, and a shoulder is formed at the connection. When the base 200 is screwed into the can opening 110, the shoulder can abut against the outer end of the can opening 110. When the outer end face of the can opening 110 is in contact with the shoulder of the base 200, it indicates that the base 200 has been tightened into place.

[0028] In some embodiments, a feed pipe 600 is also included, which communicates with the input connector 400. The feed pipe 600 extends from the base 200 toward the tank 100. The length of the feed pipe 600 is less than that of the air pipe 500, which extends to the middle of the tank 100, while the feed pipe 600 only extends to the upper part of the tank 100. The feed pipe 600 and the air pipe 500 are spaced apart to avoid interference. The feed pipe 600 and the input connector 400 are not on a straight line; that is, the central axis of the feed pipe 600 and the central axis of the input connector 400 are parallel but do not coincide.

[0029] In some embodiments, a third interface 203 communicating with the input connector 400 is also provided on the side wall of the outer section of the tank. A sealing plug is screwed into the third interface 203. The center line of the third interface 203 is perpendicular to the central axis of the feed pipe 600.

[0030] Furthermore, an intermediate channel 220 is provided in the base 200 to connect the third interface 203 and the feed pipe 600. The feed pipe 600 is connected to the lower part of the first end of the intermediate channel 220, the third interface 203 is connected to the end of the second end of the intermediate channel 220, and the input connector 400 is connected to the top of the middle part of the intermediate channel 220.
