[0002] Nitrogen, a commonly used gas in industrial production, is widely applied in chemical engineering, food preservation, and electronics manufacturing, among other fields, making its safe storage crucial. During transportation, loading and unloading, and daily use, nitrogen storage tanks are frequently damaged by external forces such as collisions and vibrations, affecting not only the quality of stored nitrogen but also potential safety hazards like leaks. Furthermore, traditional protective structures for nitrogen storage tanks often neglect optimizing sealing performance, allowing moisture and impurities from the external environment to easily enter the tank, reducing nitrogen purity and impacting its effectiveness. Current technologies for protecting nitrogen storage tanks suffer from limitations such as limited protective functions and inadequate sealing, failing to meet the growing demands of industrial production for the safety and stability of nitrogen storage. Therefore, a more efficient and reliable protective structure is urgently needed to ensure the safe operation of nitrogen storage tanks. Summary of the Invention

[0003] The purpose of this invention is to provide a protective structure for nitrogen production storage tanks to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a protective structure for a storage tank used in nitrogen production, comprising a protective frame, wherein a bearing base plate is fitted at the bottom end of the protective frame and a bearing top plate is fitted at the top end of the protective frame;

[0005] The top of the supporting base plate is fitted with a sleeve inside the protective frame, and a nitrogen storage tank is fitted inside the sleeve.

[0006] The inner walls on both sides of the protective frame are provided with openings, and guide cylinders are installed in the openings. Guide components are assembled inside the guide cylinders.

[0007] A protective pad a is installed at the end of one side of the guide assembly, and a protective pad b is installed at the end of the other side of the guide assembly;

[0008] The protective pads a and b are fitted onto the outside of the nitrogen storage tank.

[0009] The top left and right sides of the protective frame are provided with guide cavities, which are connected to the through opening;

[0010] Guide plates are installed on both the left and right sides of the bottom of the supporting top plate. The guide plates are inserted into the guide cavity, and the end of the guide assembly is attached to the guide plate.

[0011] As a preferred embodiment of the protective structure for a nitrogen production storage tank according to this utility model, the guide assembly includes a fixed plate installed on the outer wall of the protective pad a and the guide pad b. A pressing rod is installed on the side wall of the fixed plate. The pressing rod is disposed inside the guide cylinder. The end of the pressing rod extends into the guide cavity and is fitted with a universal seat. A universal ball is installed inside the universal seat and is fitted into the guide plate.

[0012] As a preferred protective structure for a nitrogen production storage tank according to this utility model, the inner wall of the universal seat is provided with rotating cavities evenly spaced along its axis, and ball bearings are installed inside the rotating cavities, with the ball bearings fitting snugly against the universal ball bearings.

[0013] As a preferred embodiment of the protective structure for a nitrogen production storage tank of this utility model, equipment slots are provided on the top left and right sides of the protective frame and at both ends of the guide cavity.

[0015] As a preferred embodiment of the protective structure for a nitrogen production storage tank according to this utility model, the side wall of the protective frame is hinged with a closed door.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the protective structure for the nitrogen production storage tank is reasonably designed;

[0017] This protective structure for nitrogen storage tanks uses a sleeve to support the bottom of the nitrogen storage tank. At the same time, guide components are installed in the guide cylinders on both sides of the protective frame. The protective pads a and b at the ends of the guide components are fitted onto the outside of the nitrogen storage tank. This structure can buffer and protect the nitrogen storage tank from multiple directions, effectively resisting the impact of external collisions and vibrations, greatly improving the damage resistance of the storage tank, and ensuring the integrity and safety of the nitrogen storage tank.

[0018] The universal joint and universal ball in the guide assembly cooperate, and the inner wall of the universal joint is equipped with ball bearings, which makes the guide assembly move more flexibly and smoothly in the guide cylinder.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] In this technical solution, a protective structure for a nitrogen production storage tank includes a protective frame 2. A supporting base plate 1 is mounted at the bottom of the protective frame 2, and a supporting top plate 3 is mounted at the top of the protective frame 2. A sleeve 5 is mounted inside the top of the supporting base plate 1 within the protective frame 2, and a nitrogen storage tank 4 is fitted inside the sleeve 5. Both sides of the inner wall of the protective frame 2 have openings 8, and guide cylinders 7 are installed within the openings 8. Guide components 15 are mounted inside the guide cylinders 7. A protective pad a14 is installed at the end of one guide component 15, and a protective pad b16 is installed at the end of the other guide component 15. Protective pads a14 and b16 are fitted onto the outside of the nitrogen storage tank 4. Guide cavities 13 are opened at the center of both the left and right sides of the top of the protective frame 2, and the guide cavities 13 are connected to the openings 8. Guide inserts 11 are installed on both the left and right sides of the bottom of the supporting top plate 3, and the guide inserts 11 are inserted into the guide cavities 13. The ends of the guide components 15 are fitted with the guide inserts 11.

[0029] The protective frame 2 serves as the main framework of the entire protective structure. The supporting base plate 1 and supporting top plate 3 are installed at its bottom and top respectively, forming a complete closed frame structure. The supporting base plate 1 provides stable bottom support for the entire protective structure, while the supporting top plate 3, in conjunction with the protective frame 2, provides top protection for the internal nitrogen storage tank and also provides a foundation for the installation of other components. Together with the protective frame 2, they form a robust outer shell that encloses the nitrogen storage tank, resisting direct environmental impacts such as collisions, dust, and moisture, ensuring the safety and stability of the nitrogen storage tank.

[0030] The sleeve 5 is installed on the supporting base plate 1 and located inside the protective frame 2. Its main function is to position and support the nitrogen storage tank 4 from the bottom. The sleeve 5, fitted onto the nitrogen storage tank 4, restricts the horizontal movement of the tank, ensuring its fixed position within the protective structure and preventing it from shaking or even tipping over due to transportation, vibration, or other factors. Simultaneously, the sleeve 5 also disperses the vertical pressure on the tank to a certain extent, evenly transmitting the pressure to the supporting base plate 1, enhancing the stability of the entire structure and reducing the risk of damage to the tank due to uneven stress.

[0031] The openings 8 on both inner walls of the protective frame 2 and the installation of guide cylinders 7 provide space and a guide track for the installation and operation of the guide assembly 15. The guide cylinders 7 guide the guide assembly 15 to move in a specific direction, ensuring the accuracy and stability of its movement. The guide assembly 15 can extend, retract, or move in a certain direction within the guide cylinders 7. When the nitrogen storage tank is subjected to external impact or vibration, the guide assembly 15 can respond promptly, buffering the external force through its own movement and deformation, thus protecting the nitrogen storage tank. This design allows the protective structure to effectively protect against impacts from external forces in different directions.

[0032] Protective pads a14 and b16 are respectively installed at the ends of the guide assemblies 15 on both sides and are fitted onto the outside of the nitrogen storage tank 4. They are made of elastic cushioning materials, such as rubber or sponge. When the nitrogen storage tank is subjected to a side impact or vibration, protective pads a14 and b16 can directly contact the storage tank, absorbing and dispersing the impact force through their own elastic deformation, preventing the storage tank from directly colliding with the hard protective frame or other components, thus providing cushioning and protection for the storage tank. At the same time, the two protective pads are positioned opposite each other, providing all-round side protection for the storage tank and enhancing the protective effect.

[0033] The guide cavity 13 at the top of the protective frame 2 is connected to the through-hole 8, providing an insertion channel and guidance for the guide plate 11 of the supporting top plate 3. The guide plate 11 is inserted into the guide cavity 13, allowing the supporting top plate 3 to move smoothly along a fixed direction during lifting and lowering, ensuring the accuracy of the relative position between the supporting top plate 3 and the protective frame 2, and preventing the supporting top plate 3 from shifting or tilting during lifting and lowering. The end of the guide assembly 15 is in contact with the guide plate 11. When the supporting top plate 3 is lifted and lowered, it pushes the guide plate 11 to move, thereby causing the guide assembly 15 to extend and retract within the guide cylinder 7. This structural design achieves linkage between the supporting top plate 3 and the guide assembly 15, allowing the supporting top plate 3 to push the guide assembly 15 during descent, ensuring that the protective pads a14 and b16 are tightly fitted onto the nitrogen storage tank, enhancing the protection of the storage tank; when the supporting top plate 3 rises, the guide assembly 15 can also reset accordingly, facilitating operation of the nitrogen storage tank.

[0034] In some technical solutions, the guide assembly 15 includes a fixing plate 151 installed on the outer wall of the protective pad a14 and the guide pad b16. A pressing rod 152 is installed on the side wall of the fixing plate 151. The pressing rod 152 is disposed in the guide cylinder 7. The end of the pressing rod 152 extends into the guide cavity 13 and is installed with a universal seat 153. A universal ball 154 is installed inside the universal seat 153. The universal ball 154 is fitted with the guide insert plate 11.

[0035] The fixing plate 151 is used to fix the outer walls of the protective pads a14 and b16, providing a mounting base for the extrusion rod 152, connecting the protective pads and the extrusion rod into a whole, so that the protective pads can move with the movement of the extrusion rod. The extrusion rod 152 is set inside the guide cylinder 7, and can extend and retract within the guide cylinder 7 when subjected to external force, thereby adjusting the position of the protective pad and providing buffer protection for the nitrogen storage tank. The cooperation between the universal seat 153 and the universal ball 154 at the end of the extrusion rod 152 allows the extrusion rod 152 to rotate flexibly when in contact with the guide plate 11. When the supporting top plate 3 rises and falls, driving the guide plate 11 to move, the universal ball 154 can rotate freely within the universal seat 153 regardless of the direction of movement of the guide plate 11, ensuring that the extrusion rod 152 and the guide plate 11 always maintain a good fit, ensuring that the guide assembly 15 can smoothly extend and retract with the movement of the supporting top plate 3, and achieving effective protection for the nitrogen storage tank.

[0036] In some technical solutions, the inner wall of the universal seat 153 is provided with rotating cavities 155 evenly spaced along its axis, and ball bearings 156 are installed inside the rotating cavities 155, which are fitted together with the universal ball 154.

[0037] The rotating cavity 155 is formed in the inner wall of the universal seat 153, and the ball bearing 156 is installed therein to further reduce the frictional resistance between the universal ball 154 and the universal seat 153. The ball bearing 156 fits snugly against the universal ball 154. When the universal ball 154 rotates within the universal seat 153, the ball bearing 156 can roll within the rotating cavity 155, converting the sliding friction between the universal ball 154 and the universal seat 153 into rolling friction, greatly reducing friction. This makes the universal ball 154 more flexible and smooth during rotation, enabling it to adapt more quickly and accurately to changes in the movement direction of the guide plate 11, ensuring the flexibility and stability of the guide assembly 15 throughout the entire movement process. This improves the protection effect on the nitrogen storage tank, reduces component wear and jamming caused by frictional resistance, and extends the service life of the protective structure.

[0038] In some technical solutions, equipment slots 12 are provided on the top left and right sides of the protective frame 2 and at both ends of the guide cavity 13. Electric push rods 10 are installed inside the equipment slots 12, and the drive end of the electric push rods 10 is connected to the bearing top plate 3.

[0039] The equipment slot 12 provides installation space for the electric actuator 10, concealing it within the protective frame 2. This ensures a clean appearance for the entire protective structure while also protecting the actuator 10 from external impacts and damage. The drive end of the electric actuator 10 connects to the supporting top plate 3, enabling automatic raising and lowering of the top plate 3 through its extension and retraction. Compared to traditional manual operation, the electric actuator 10 significantly improves ease of operation and efficiency. Operators can easily raise and lower the top plate 3 by controlling the electric actuator 10's switch or related control system, eliminating the need for extensive manual labor. Furthermore, the electric actuator 10's raising and lowering motion is smoother and more accurate, precisely controlling the position of the top plate 3 and ensuring the precise fit between the top plate 3 and the protective frame 2. This guarantees the normal operation of the protective structure and effective protection of the nitrogen storage tank. In addition, electric operation reduces the safety risks associated with manual operation, improving overall safety.

[0040] In some technical solutions, a sealing cover 9 is installed at the bottom center of the supporting top plate 3, and the sealing cover 9 is fastened to the top of the nitrogen storage tank 5.

[0041] The sealing cover 9 is installed at the center of the bottom end of the supporting top plate 3. Its shape is adapted to the top of the nitrogen storage tank. When the supporting top plate 3 is lowered, the sealing cover 9 can accurately fasten to the top of the nitrogen storage tank. The sealing cover 9 is made of materials with good sealing performance, such as rubber and silicone. Through its tight fit with the top of the nitrogen storage tank, it forms a sealed space, effectively isolating external air, moisture, dust, and impurities from entering the nitrogen storage tank. This is crucial for ensuring the quality of nitrogen storage, preventing external substances from reacting with or contaminating the nitrogen, ensuring that the purity and performance of the nitrogen are not affected, and meeting the stringent requirements for nitrogen quality in industrial production. At the same time, good sealing performance also prevents nitrogen leakage, avoiding safety hazards and resource waste caused by nitrogen leakage.

[0042] In some technical solutions, the side wall of the protective frame 2 is hinged with a closed door 6.

[0043] The sealing door 6 is hinged to the side wall of the protective frame 2. This connection allows the sealing door 6 to rotate freely around the hinge point, enabling opening and closing. When it is necessary to inspect, maintain, fill, or replace the nitrogen storage tank, the sealing door 6 can be opened to allow personnel to enter the protective frame 2 for related operations. When the sealing door 6 is closed, it fits tightly against the protective frame 2, ensuring the airtightness of the protective structure and preventing the external environment from affecting the internal nitrogen storage tank, thus providing the same protective function as other parts of the protective frame. At the same time, the hinged design makes the installation and disassembly of the sealing door 6 relatively simple, facilitating maintenance or replacement when needed, and improving the practicality and maintainability of the entire protective structure.

[0044] Working process and principle:

[0045] Installation process: First, place the base plate 1 in a suitable position to provide a stable support foundation for the entire protective structure. Then, insert the nitrogen storage tank 4 into the sleeve 5 located inside the protective frame 2 at the top of the base plate 1. The sleeve 5 positions and supports the nitrogen storage tank 4 from the bottom, restricting its horizontal movement and distributing vertical pressure. Next, install the protective frame 2 onto the base plate 1. Then, insert the top plate 3 into the guide cavity 13 at the top of the protective frame 2 via the guide plate 11 at its bottom, completing the construction of the protective structure frame.

[0046] Protective activation process: The electric push rod 10 is activated, driving the supporting top plate 3 to descend. As the supporting top plate 3 descends, its guide plate 11 moves within the guide cavity 13. Since the end of the guide assembly 15 is in contact with the guide plate 11, the movement of the guide plate 11 pushes the universal ball 154. The universal ball 154 rotates within the universal seat 153, causing the compression rod 152 to extend and retract within the guide cylinder 7, thereby ensuring that the protective pads a14 and b16 are tightly fitted to the outside of the nitrogen storage tank 4. Simultaneously, the sealing cover 9 at the center of the bottom of the supporting top plate 3 accurately engages with the top of the nitrogen storage tank 4, forming a sealed space that isolates external impurities and moisture, preventing nitrogen leakage and ensuring the quality of nitrogen storage.

[0047] Protective Operation Process: When the nitrogen storage tank 4 is subjected to external impact or vibration, the impact forces from all directions first act on the protective pads a14 and b16. Protective pads a14 and b16 are made of elastic cushioning material, which absorbs and disperses the impact force through their elastic deformation, preventing direct collision between the storage tank and hard components such as the protective frame 2. If the impact force causes displacement of protective pads a14 and b16, the compression rod 152 will extend and retract accordingly within the guide cylinder 7, and the universal ball 154 will rotate flexibly within the universal seat 153, ensuring that the compression rod 152 remains in contact with the guide plate 11. This allows the entire guide assembly 15 to stably provide cushioning protection for the nitrogen storage tank 4, ensuring the safety of the storage tank.

[0048] Maintenance Process: When it is necessary to inspect, maintain, refill, or replace nitrogen storage tank 4, activate the electric push rod 10 to drive the supporting top plate 3 upward, causing the guide plate 11 to move upward within the guide cavity 13. The guide assembly 15 then resets, separating the protective pads a14 and b16 from the nitrogen storage tank 4. Then, open the hinged sealing door 6 on the side wall of the protective frame 2, allowing personnel to enter the protective frame 2 to perform relevant operations on the nitrogen storage tank 4. After the operation is completed, close the sealing door 6 and activate the electric push rod 10 again to lower the supporting top plate 3, restoring the protection and sealing of the nitrogen storage tank 4.
