Description

Technical Field

[0001] This utility model relates to the field of hydrogen storage device technology, and in particular to a safe hydrogen storage device with a protective structure. Background Technology

[0002] Hydrogen energy is the energy produced by the reaction of hydrogen and oxygen. Hydrogen energy is the chemical energy of hydrogen. Hydrogen mainly exists on Earth in a combined state and is the most widely distributed substance in the universe, constituting 75% of the universe's mass. Hydrogen can be stored through liquid hydrogen storage methods, and liquid hydrogen produced by the adiabatic expansion of hydrogen gas can be used as a storage state for hydrogen.

[0003] In existing technologies, hydrogen leaks in hydrogen storage devices lead to energy waste and pose a risk of serious safety accidents such as explosions. Furthermore, recovering leaked hydrogen is difficult, resulting in wasted hydrogen and requiring significant time and manpower; the recovery and reuse of leaked hydrogen is also challenging; and the protective structures of hydrogen storage devices are often inadequate. When subjected to impacts, they cannot effectively and promptly block the impact force, nor can they provide sufficient time and space for subsequent cushioning measures, making the storage tank highly susceptible to damage due to excessive localized stress. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art where hydrogen is difficult to recover when it leaks and the storage tank is damaged when it collides with another tank, and to propose a safe hydrogen storage device with a protective structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a safe hydrogen storage device with a protective structure, comprising a storage tank, a support base installed at the bottom of the storage tank, a fixing sleeve installed on the outer wall of the storage tank, a protective cover fixedly connected to the top of the fixing sleeve by bolts, an exhaust port opened at the top of the protective cover, an anti-leakage component installed inside the exhaust port, a protective component installed on the outer wall of the support base, a fixing pile fixedly connected to the side of the bottom end of the support base, and the protective component and the fixing pile fixedly connected by a connecting rod.

[0006] Furthermore, the leak-proof component includes a fixing block and a plugging block. The fixing block is fixedly connected to the top of the inner side of the protective cover. A telescopic spring is fixedly connected to the lower surface of the fixing block. A connecting block is fixedly connected to the end of the telescopic spring away from the fixing block. The connecting block is fixedly connected to the outer wall of the plugging block, providing good leak prevention and controllable air extraction.

[0007] Furthermore, the protective component includes a retaining ring located on the outer wall of the support base, and a buffer structure is fixedly connected to the inner wall near the retaining ring to effectively protect the storage tank from external impact damage.

[0008] Furthermore, the buffer structure includes a buffer spring, one end of which is fixedly connected to the inner wall of the fixing ring, and the other end of which is fixedly connected to an arc-shaped plate, thereby enhancing the buffering effect and providing all-round protection for the storage tank.

[0009] Furthermore, the fixed pile includes an extension block, one end of which is fixedly connected to the side of the bottom of the support base, and the other end of which is fixedly connected to a support plate. The support plate is internally threaded with a fixed column to enhance the stability of the device and prevent it from shifting or tipping over during use.

[0010] Furthermore, the connecting rod includes a support rod and a mounting plate. The mounting plate is fixedly connected to the outer wall of the fixing ring, and the support rod is connected through the interior of the mounting plate. The bottom end of the support rod is fixedly connected to the top of the extension block, thereby improving the overall structural stability.

[0011] Furthermore, the buffer structure has four groups arranged in a circle on the inner wall of the fixing ring, and the surface of the fixing ring is mounted with blocks, which are fixedly connected by bolts to improve the protective effect and maintenance convenience.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this invention, by setting a unique anti-leakage component at the extraction port, and utilizing the cooperation of a telescopic spring and a plug, a good seal can be formed under normal hydrogen storage conditions, effectively preventing hydrogen leakage from the extraction port and greatly improving the safety of the hydrogen storage process. This is something that existing technologies cannot achieve in terms of sealing. Moreover, when extraction is needed, the plug can be pressed by a simple extraction device to achieve extraction, which is convenient to operate and facilitates the recovery of leaked hydrogen.

[0014] 2. In this utility model, through the setting of protective components and the combination of the fixing ring and the buffer structure, when the device is subjected to external impact, the fixing ring first blocks part of the impact force, giving the buffer structure time and space to play its role. The buffer spring and arc-shaped plate in the buffer structure work together to convert the impact energy into elastic potential energy for storage, and evenly distribute the impact force to the surface of the storage tank, avoiding excessive local stress, and providing all-round protection for the storage tank from collision damage, thus enhancing its protective capability.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a safe hydrogen storage device with a protective structure, including a storage tank 1, a support base 2 installed at the bottom of the storage tank 1, a fixing sleeve 3 installed on the outer wall of the storage tank 1, a protective cover 4 fixedly connected to the top of the fixing sleeve 3 by bolts, an exhaust port 41 opened on the top of the protective cover 4, an anti-leakage component 42 installed inside the exhaust port 41, a protective component 21 installed on the outer wall of the support base 2, a fixing pile 22 fixedly connected to the side of the bottom end of the support base 2, and the protective component 21 and the fixing pile 22 fixedly connected by a connecting rod 23.

[0023] The specific settings and functions of the leak prevention component 42 and the protection component 21 will be explained below.

[0024] In this embodiment: the anti-leakage component 42 includes a fixing block 421 and a plugging block 424. The fixing block 421 is fixedly connected to the top of the inner side of the protective cover 4. A telescopic spring 422 is fixedly connected to the lower surface of the fixing block 421. A connecting block 423 is fixedly connected to the end of the telescopic spring 422 away from the fixing block 421. The connecting block 423 is fixedly connected to the outer wall of the plugging block 424.

[0025] The aforementioned components achieve the following effects: Under normal hydrogen storage conditions, the telescopic spring 422 is in a naturally extended or slightly compressed state, pressing the plug 424 tightly against the vent 41, forming a good seal and effectively preventing hydrogen leakage from the vent 41. When venting is required for the storage tank 1, the vent pipe of the external venting equipment is aligned with the vent 41. The suction force generated by the venting equipment is greater than the elastic force of the telescopic spring 422, overcoming the spring resistance and pulling up the plug 424, thus opening the vent 41 and achieving the venting function. After venting is completed, the venting equipment is removed, the telescopic spring 422 returns to its original state, pushing the plug 424 to re-block the vent 41, ensuring a seal once again.

[0026] In this embodiment: the protective component 21 includes a fixing ring 211, which is located on the outer wall of the support base 2, and a buffer structure 213 is fixedly connected to the inner wall near the fixing ring 211.

[0027] The effect achieved by the above components is that when the device is subjected to an external impact, the fixing ring 211 first contacts and blocks part of the impact force, which buys time and buffer space for the buffer structure 213 to play its role, and initially protects the storage tank 1 and the support base 2 from direct impact.

[0028] Specifically, the buffer structure 213 includes a buffer spring 2131, one end of which is fixedly connected to the inner wall of the fixing ring 211, and the other end of which is fixedly connected to an arc-shaped plate 2132.

[0029] The effect achieved by the above components is as follows: when the fixed ring 211 is subjected to impact force, the buffer spring 2131 is compressed and deformed, converting the impact energy into elastic potential energy and storing it. The arc plate 2132 is tightly attached to the outer wall of the storage tank 1, distributing the impact force evenly to the surface of the storage tank 1, avoiding excessive local stress, thereby protecting the storage tank 1 from collision damage in all directions.

[0030] Specifically, the fixed pile 22 includes an extension block 221, one end of which is fixedly connected to the side of the bottom of the support base 2, and the other end of which is fixedly connected to a support plate 222. The support plate 222 is internally threaded with a fixed post 223.

[0031] The effect achieved by the above components is that after the device is moved to the predetermined position, the fixed column 223 is rotated, so that it gradually penetrates into the ground under the action of the thread of the support plate 222 until the entire hydrogen storage device is firmly fixed to the ground, thereby enhancing the stability of the device during use.

[0032] Specifically, the connecting rod 23 includes a support rod 231 and a mounting plate 232. The mounting plate 232 is fixedly connected to the outer wall of the fixing ring 211. The support rod 231 is connected through the interior of the mounting plate 232. The bottom end of the support rod 231 is fixedly connected to the top of the extension block 221.

[0033] The effect achieved by the above components is that the connecting rod 23 securely connects the protective component 21 to the fixed pile 22, thereby improving the overall structural stability of the entire hydrogen storage device.

[0034] Specifically, the buffer structure 213 has four sets of circularly distributed on the inner wall of the fixing ring 211, and the surface of the fixing ring 211 is mounted with blocks, which are fixedly connected by bolts.

[0035] The effect achieved by the above components is that the four sets of evenly distributed circular buffer structures 213 can provide all-round buffer protection for the storage tank 1. No matter which direction the impact comes from, the corresponding buffer structure 213 can play its role.

[0036] Working Principle: During normal operation of the hydrogen storage device, storage tank 1 is used to store hydrogen. The leak-proof component 42 ensures the seal at the vent 41, preventing hydrogen leakage. In the event of an external collision, the retaining ring 211 in the protective component 21 first blocks part of the impact force. Then, the buffer spring 2131 and the arc-shaped plate 2132 of the buffer structure 213 work together to absorb and disperse the impact energy, protecting storage tank 1. The fixing pile 22, by extending deep into the ground, firmly fixes the entire device to the ground, preventing displacement or tipping due to collisions or other external forces. The connecting rod 23 ensures the structural stability between the protective component 21 and the fixing pile 22, enabling all components to work together and ensuring the safe and stable operation of the hydrogen storage device. When venting or other operations are required on storage tank 1, an external venting device is connected to the vent 41. Using the elasticity of the telescopic spring 2131, the plug 424 is pressed to achieve venting. After the operation is completed, the seal is automatically restored.
