Technical Field

[0001] This utility model relates to the field of hydrogen storage tank technology, specifically a hydrogen storage tank with a buffer function. Background Technology

[0002] With the increasing global demand for clean energy, hydrogen, as an efficient, clean, and renewable energy carrier, is being used more and more widely in the energy sector. Hydrogen storage tanks, as key equipment for hydrogen storage and transportation, are of paramount importance in terms of safety and stability. However, existing hydrogen storage tanks still have certain shortcomings, such as:

[0003] The application CN201920792082.6, entitled "An Ultra-High Pressure Hydrogen Storage Tank", lacks a buffer function during use. The hydrogen storage tank is easily damaged by external vibrations and collisions, which is detrimental to ensuring the safety of the hydrogen storage tank and limits its use. In view of this, a hydrogen storage tank with a buffer function is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a hydrogen storage tank with a buffer function, in order to solve the problem mentioned in the background art that the existing hydrogen storage tanks do not have a buffer function and are easily damaged by collisions, which is not conducive to ensuring the safety of the hydrogen storage tanks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydrogen storage tank with buffering function, comprising a tank body;

[0006] A base is fixedly installed on the bottom surface of the tank, and a first outer shell and a second outer shell are provided on the outside of the tank. The first outer shell and the second outer shell are detachably connected by a disassembly and assembly mechanism. The first outer shell and the second outer shell are fitted together to fit against the outer circumference of the tank. Rubber protective pads are fixedly installed on the outer sides of both the first outer shell and the second outer shell.

[0007] The above technical solution facilitates the enclosure and protection of the tank through the first and second outer shells; the rubber protective pad uses elastic material to absorb the impact force of external collisions, reducing the risk of tank damage and improving the safety and impact resistance of the storage tank.

[0008] As a preferred technical solution of this utility model, the disassembly and assembly mechanism includes a plug block, which is fixedly installed on the upper inner side of the first housing, and two plug blocks are symmetrically arranged front and back. The top surface of the plug block is provided with a plug hole, and the plug block is movably inserted into a slot. The slot is opened on the upper inner side of the second housing, and the top of the slot is provided with a threaded hole, which extends to the top surface of the second housing. A threaded rod is threadedly connected to the threaded hole, and the threaded rod is movably inserted into the plug hole.

[0009] By adopting the above technical solution, the first and second housings can be initially positioned by the insertion and engagement of the plug and slot. Then, the threaded rod passes through the threaded hole and is inserted into the plug hole to form a detachable fast connection. This not only ensures the stability of the housing assembly, but also facilitates quick disassembly and maintenance, improving operational convenience.

[0010] As a preferred embodiment of this utility model, positioning rods are fixedly installed on the bottom surfaces of both the first outer shell and the second outer shell, and two positioning rods are symmetrically arranged on the bottom surfaces of both the first outer shell and the second outer shell. The positioning rods are movably inserted into positioning holes, and the positioning holes are opened on the top surface of the base.

[0011] By adopting the above technical solution, the installation position of the outer shell can be precisely defined by inserting the positioning rod into the positioning hole of the base when installing the first outer shell and the second outer shell, so as to avoid protective gaps or unstable connections caused by misalignment, and enhance the assembly accuracy and stability of the overall structure of the storage tank.

[0012] As a preferred technical solution of this utility model, the inner wall of the rubber protective pad is provided with a groove, and multiple sets of the groove are evenly arranged at equal intervals along the height direction of the rubber protective pad. Each set of the grooves is evenly arranged at equal angles in the horizontal direction, and a rubber support strip is fixedly arranged inside each groove.

[0013] The above technical solution facilitates the use of the combination structure of grooves and rubber support strips. When the rubber protective pad is impacted, the grooves can absorb energy through deformation, while the rubber support strips provide elastic support. The two work together to enhance the buffering effect. At the same time, the uniform distribution of multiple sets of grooves and support strips can improve the adaptability of the protective pad to impact forces from different directions.

[0014] As a preferred embodiment of this utility model, a knob is coaxially fixedly installed at the top end of the threaded rod.

[0015] The above technical solution allows for easy rotation of the threaded rod via a knob, enabling disassembly and assembly without additional tools, thus simplifying the maintenance process and improving repair efficiency.

[0016] As a preferred embodiment of this utility model, the rubber support strip has a cross-shaped structure, and the four corners of the rubber support strip are fixedly connected to the four apex corners of the groove, the outer side of the rubber support strip is fixedly connected to the outer wall of the groove, and the inner side of the rubber support strip matches the inner side of the rubber protective pad.

[0017] The above technical solution facilitates the fixed connection between the cross-shaped rubber support strip and the four corners and outer wall of the groove, forming a "mesh support structure". When the rubber protective pad is compressed, the support strip can disperse the impact force through its own elastic deformation, while maintaining the shape stability of the protective pad, avoiding long-term impact that could cause the protective pad to collapse, and extending its service life.

[0018] As a preferred technical solution of this utility model, a limiting plate is threaded onto the upper outer wall of the tank, and the limiting plate is located above the first outer shell and the second outer shell.

[0019] By adopting the above technical solution, the first outer shell and the second outer shell can be limited by rotating the limiting plate to move downward, thus ensuring the overall stability.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the hydrogen storage tank with buffer function can ensure the buffer protection of the tank body during use, effectively buffer external vibration and collision, reduce damage to the tank body, and improve the safety of the hydrogen storage tank.

[0021] 1. Rubber protective pads are provided on the outer sides of the first and second outer shells, and grooves with cross-shaped rubber support strips are opened on the inner wall of the rubber protective pads. By utilizing the elasticity of the rubber material and the structural design of the grooves and rubber support strips, external vibrations and collisions can be effectively buffered, thereby improving safety in use.

[0022] 2. By interlocking the plug and slot, and connecting the threaded rod and the insertion hole, the first and second outer shells can be detachably connected, facilitating installation, maintenance and repair.

[0023] 3. The positioning rod and positioning hole work together to provide positioning during the installation of the first and second outer shells, ensuring accurate installation on the base and improving the overall stability of the storage tank structure. Attached Figure Description

[0032] Please see Figure 1 - Figure 6 The present invention provides a hydrogen storage tank with a buffer function, comprising a tank body 1, a base 2 fixedly installed on the bottom surface of the tank body 1, and a first outer shell 3 and a second outer shell 4 provided on the outside of the tank body 1. The first outer shell 3 and the second outer shell 4 are detachably connected by a disassembly and assembly mechanism. The first outer shell 3 and the second outer shell 4 are fitted together and attached to the outer circumference of the tank body 1. Rubber protective pads 5 are fixedly installed on the outer sides of both the first outer shell 3 and the second outer shell 4.

[0033] The disassembly and assembly mechanism includes a plug 6, which is fixedly installed on the upper inner side of the first housing 3. Two plugs 6 are arranged symmetrically front and back. The top surface of the plug 6 is provided with a plug hole 7. The plug 6 is movably inserted into a slot 8, which is located on the upper inner side of the second housing 4. The top of the slot 8 is provided with a threaded hole 9, which extends to the top surface of the second housing 4. A threaded rod 10 is threadedly connected to the threaded hole 9, and the threaded rod 10 is movably inserted into the plug hole 7. The diameter of the threaded rod 10 matches the diameter of the plug hole 7. A knob is coaxially fixedly installed on the top end of the threaded rod 10.

[0034] Positioning rods 11 are fixedly installed on the bottom surfaces of both the first outer shell 3 and the second outer shell 4. Two positioning rods 11 are symmetrically arranged on the bottom surfaces of both the first outer shell 3 and the second outer shell 4. The positioning rods 11 are movably inserted into the positioning holes 12, and the positioning holes 12 are opened on the top surface of the base 2. The diameter of the positioning rods 11 matches the diameter of the positioning holes 12.

[0035] The inner wall of the rubber protective pad 5 is provided with grooves 13. Multiple sets of grooves 13 are evenly arranged at equal intervals along the height direction of the rubber protective pad 5, and multiple sets of grooves 13 are evenly arranged at equal angles in the horizontal direction. A rubber support strip 14 is fixedly installed inside each groove 13.

[0036] The rubber support strip 14 has a cross-shaped structure, and the four corners of the rubber support strip 14 are fixedly connected to the four apex corners of the groove 13. The outer side of the rubber support strip 14 is fixedly connected to the outer wall of the groove 13, and the inner side of the rubber support strip 14 matches the inner side of the rubber protective pad 5.

[0037] A limiting plate 15 is threaded onto the upper outer wall of the tank body 1, and the limiting plate 15 is located above the first outer shell 3 and the second outer shell 4.

[0038] Working principle: During installation, the first outer shell 3 and the second outer shell 4 are placed on both sides of the tank body 1, and the two inserts 6 on the upper inner side of the first outer shell 3 are inserted into the slots 8 on the upper inner side of the second outer shell 4 to complete the initial positioning; then the initially positioned first outer shell 3 and second outer shell 4 are moved downwards, and the positioning rod 11 is inserted into the positioning hole 12 on the top surface of the base 2 through appropriate adjustment to accurately define the position of the first outer shell 3 and the second outer shell 4.

[0039] Then, turn the knob at the top of the threaded rod 10 to rotate the threaded rod 10 and move it down along the threaded hole 9 to insert it into the insertion hole 7 on the top surface of the insert block 6, firmly connecting the first outer shell 3 and the second outer shell 4, completing the wrapping of the tank 1. Then, by rotating the limiting plate 15, the rotating limiting plate 15 moves downward under the action of the threaded connection with the upper part of the tank 1, so that the limiting plate 15 abuts against the first outer shell 3 and the second outer shell 4, stably limiting and fixing the first outer shell 3 and the second outer shell 4 to prevent displacement in the vertical direction.

[0040] When subjected to external impact, the rubber protective pads 5 on the outer sides of the first shell 3 and the second shell 4 first come into contact with the impact. The groove 13 absorbs energy through deformation. The four corners of the cross-shaped rubber support strip 14 are fixed with the four apex corners of the groove 13 and the outer wall to form a mesh support structure. It disperses the impact force by its own elastic deformation, while maintaining shape stability and buffering the impact to reduce damage to the tank 1.

[0041] During maintenance, turn the knob in the opposite direction to pull out the threaded rod 10, separate the first outer shell 3 from the second outer shell 4, and then perform the repair.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
