[0002] Almost all of the existing explosion-proof devices for the outer shells of liquid hydrogen vacuum adiabatic containers are vertically installed, with guide rods or springs provided inside. After the explosion-proof device is triggered to act, the explosion-proof cover can fall back and recover through its own weight and the guidance of the internal guide rods or springs, avoiding a large amount of air entering the interlayer and causing safety accidents.

[0003] However, for products such as tank trucks, there are limitations in the external dimensions, and the explosion-proof device for the outer shell cannot be vertically installed on the top of the cylinder body. The installation position is generally on the inclined surface of the head. For the traditional resetable explosion-proof device for the outer shell, as the angle of the installation inclined surface increases, it is prone to jamming during the reset process, resulting in a situation where it cannot be reset.

[0011] Optionally, the second guiding member includes a second guiding ring and a second plate body. The second plate body is arranged outside the second guiding ring.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present application, the meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0027] Please refer to Figures 1 to 3 , this embodiment provides an explosion-proof device 100, which is arranged on the inclined surface of the outer shell 201 of the adiabatic container 200. The explosion-proof device 100 includes an explosion-proof component and a guiding component. By the cooperation of the explosion-proof component and the guiding component, after the overpressure in the interlayer space of the adiabatic container 200 is released, the explosion-proof cover 12 of the explosion-proof component can be reset smoothly to prevent the explosion-proof cover 12 from getting stuck.

[0028] Please refer to Figure 1 and Figure 2 , the explosion-proof component in this example includes an inner cover cylinder 11 and an explosion-proof cover 12. Both ends of the inner cover cylinder 11 are open and the inside is hollow. And one end of the inner cover cylinder 11 is arranged on the outer shell 201 of the adiabatic container 200, so that the hollow inside of the inner cover cylinder 11 is communicated with the inner layer of the adiabatic container 200. The explosion-proof cover 12 is arranged at the opening at the other end of the inner cover cylinder 11 to seal the inner cover cylinder 11.

[0029] Specifically, the inner cover cylinder 11 of this embodiment is communicated with the internal interlayer space of the heat-insulating container 200, and an explosion-proof cover 12 connected to the opening of the inner cover cylinder 11 is provided at one end of the inner cover cylinder 11 away from the heat-insulating container 200. A connecting groove is provided on the outer edge of the explosion-proof cover 12, so that the explosion-proof cover 12 can be nested on the opening of the inner cover cylinder 11. Among them, the explosion-proof cover 12 is not fixed to the inner cover cylinder 11. When the gas in the heat-insulating container 200 rushes out of the inner cover cylinder 11 for pressure relief, the explosion-proof cover 12 can be pushed open for pressure relief. In this embodiment, a gasket is further provided on the connecting end face between the explosion-proof cover 12 and the inner cover cylinder 11 for shock absorption when the explosion-proof cover 12 is reset. Moreover, the gasket can increase the tightness between the explosion-proof cover 12 and the inner cover cylinder 11 to prevent external gas from entering the inner cover cylinder 11.

[0030] Please refer to Figure 1 and Figure 2 , the explosion-proof assembly further includes a protective cover 13. The protective cover 13 is a cylindrical structure with one end open, and the protective cover 13 is connected to the inner cover cylinder 11 to cover the opening of the inner cover cylinder 11.

[0031] As Figure 1 and Figure 2 shown, the protective cover 13 of this embodiment is detachably connected to the outer side surface of the inner cover cylinder 11, and the protective cover 13 is buckled on the inner cover cylinder 11, which can prevent the explosion-proof cover 12 from flying out and hitting the operator. And the protective cover 13 can also prevent external objects from entering the inner cover cylinder 11 after the explosion-proof cover 12 is opened. The protective cover 13 of this embodiment is in a cylindrical structure, and the gas in the heat-insulating container 200 can also flow out through the gap at the connection between the protective cover 13 and the inner cover cylinder 11, so that the heat-insulating container 200 can be smoothly pressure-relieved.

[0032] Please continue to refer to Figures 1 to 4 , the explosion-proof device 100 further includes a guiding assembly, and the guiding assembly is used to guide the movement of the explosion-proof cover 12 and enable the explosion-proof cover 12 to be smoothly reset under the action of gravity to re-cover the opening of the inner cover cylinder 11.

[0033] Please refer to Figures 1 to 3 , the guiding assembly in this embodiment includes a guiding member and a guiding rod 22. The guiding member is fixedly arranged on the axial extension path of the inner cover cylinder 11, and a guiding hole is provided in the guiding member. A protrusion 24 is provided on the side wall of the guiding hole. One end of the guiding rod 22 is connected to the explosion-proof cover 12, and the other end passes through the guiding hole. When the explosion-proof cover 12 is opened or closed, the guiding rod 22 moves in the guiding hole. At this time, a point contact is formed between the outer wall of the guiding rod 22 and the protrusion 24.

[0034] The guiding holes on the guiding member cooperate with the guiding rods 22 on the explosion-proof cover 12, enabling the explosion-proof cover 12 to reciprocate along a fixed path to open or close the opening of the inner cover cylinder 11. When the pressure in the interlayer of the heat-insulating container 200 is too high, it pushes the explosion-proof cover 12 to move along the axial direction of the inner cover cylinder 11 to open the opening of the inner cover cylinder 11. When the pressure in the heat-insulating container 200 is emptied, the explosion-proof cover 12, under the action of gravity, overcomes the friction between the guiding rod 22 and the guiding hole to reset and re-close the opening on the inner cover cylinder 11.

[0035] Please refer to Figure 4 , on the inner sidewall of the guiding hole in this embodiment, there is a protrusion 24, forming a point contact between the guiding rod 22 and the guiding hole, which can minimize the friction between the guiding rod 22 and the guiding hole to the greatest extent. When the explosion-proof device 100 is installed on the inclined surface of the outer shell 201 of the heat-insulating container 200, that is, when the explosion-proof cover 12 moves in an inclined direction, the explosion-proof cover 12 can also be smoothly reset under the action of gravity.

[0036] Please refer to Figures 1 to 3 , the guiding member in this embodiment includes a first guiding member 21 and a second guiding member 23. The first guiding member 21 is arranged inside the inner cover cylinder 11, and the second guiding member 23 is arranged inside the explosion-proof cover 12. Correspondingly, there are also two guiding rods 22, namely a first guiding rod 221 and a second guiding rod 222, which respectively cooperate with the guiding holes opened on the first guiding member 21 and the second guiding member 23 on both sides of the explosion-proof cover 12 to guide the explosion-proof cover 12 in both the up and down directions.

[0037] Specifically, the first guiding member 21 includes a first guiding ring 211 and a first plate body 212. The first plate body 212 is arranged on the outer side of the first guiding ring 211. Both ends of the first guiding ring 211 are open and the interior is hollow to form a first guiding hole. The first guiding ring 211 is arranged in the hollow cavity of the inner cover cylinder 11, and the first guiding ring 211 is connected to the inner sidewall of the inner cover cylinder 11 through the first plate body 212, so that the first guiding hole on the first guiding ring 211 can be located on the axis of the inner cover cylinder 11. On the surface of the explosion-proof cover 12 facing the inner cover cylinder 11, there is a first guiding rod 221, and the first guiding rod 221 passes through the first guiding hole in the first guiding ring 211, enabling the explosion-proof cover 12 to move along the axial direction of the first guiding hole in the first guiding ring 211.

[0038] The second guiding member 23 includes a second guiding ring 231 and a second plate body 232. The second plate body 232 is disposed on the outer side of the second guiding ring 231. Both ends of the second guiding ring 231 are open and the interior thereof is hollow to form a second guiding hole. The second guiding ring 231 is disposed within the protective cover 13, and the second guiding ring 231 is connected to the inner side wall of the protective cover 13 through the second plate body 232. The second guiding ring 231 is fixed within the protective cover 13, and the second guiding hole of the second guiding ring 231 is coaxial with the first guiding hole of the first guiding ring 211 and both are located on the axial extension path of the inner cover cylinder 11. A second guiding rod 222 is provided on a side surface of the explosion-proof cover 12 facing away from the inner cover cylinder 11. The second guiding rod 222 is inserted into the second guiding hole within the second guiding ring 231 to further guide the explosion-proof cover 12.

[0039] Through the cooperation of the first guiding rod 221 and the second guiding rod 222 on both side surfaces of the explosion-proof cover 12 with the guiding holes on the first guiding ring 211 and the second guiding ring 231, two-way guiding and limiting are performed. The movement path of the explosion-proof cover 12 is restricted from the upper and lower directions, which can make the reciprocating movement of the explosion-proof cover 12 smoother, reduce the risk of jamming of the explosion-proof cover 12, and enable the explosion-proof cover 12 on the guiding rod 22 to be reset by its own weight even when moving in an inclined direction.

[0040] In some other embodiments, only the first guiding member 21 disposed within the inner cover cylinder 11 can be used for guiding. That is, only the first guiding ring 211 and the first plate body 212 are provided. The first guiding ring 211 is connected to the inner cover cylinder 11 through the first plate body 212, and the first guiding hole on the first guiding ring 211 is located on the axis of the inner cover cylinder 11. The corresponding guiding rod 22 only includes the first guiding rod 221. Guiding is performed through the cooperation of the first guiding rod 221 and the first guiding hole on the first guiding ring 211, which can simplify the structure of the explosion-proof device 100 and reduce costs.

[0041] It can be conceived that a plurality of guiding rings can be provided on the axial extension path of the inner cover cylinder 11. The plurality of guiding rings can be arranged arbitrarily and disposed on both sides of the explosion-proof cover 12 to guide the movement path of the explosion-proof cover 12, restrict the movement path of the explosion-proof cover 12, and guide the explosion-proof cover 12.

[0042] Providing a guiding ring on one side of the explosion-proof cover 12 can simplify the structure of the explosion-proof device 100 and reduce the manufacturing cost. Guiding rings are provided on both sides of the explosion-proof cover 12 to achieve two-way guiding, which can prevent the explosion-proof cover 12 from being jammed when being reset under the action of gravity. The two-way guiding structure and the protrusions 24 within the guiding holes cooperate together, which can further reduce the friction force at each position of the protrusions 24 and solve the technical problem that the explosion-proof cover 12 cannot be reset smoothly when the explosion-proof device 100 is disposed on an inclined surface.

[0043] In some embodiments, the protrusion 24 is fixedly connected to the side wall of the guiding holes in the first guiding ring 211 and the second guiding ring 231, and the top surface of the protrusion 24 is spherical.

[0044] Specifically, as Figure 4 shown, four protrusions 24 are provided on the circumferences of the inner side walls of the first guiding ring 211 and the second guiding ring 231. The top of the protrusion 24 is spherical. By abutting against the outer side wall of the guiding rod 22 through the spherical structure at the top to form point contact, the friction generated when the guiding rod 22 moves along the first guiding hole can be minimized. When the explosion-proof device 100 is on an inclined plane, the explosion-proof cover 12 can also be smoothly reset under the action of its own gravity, preventing a large amount of air from entering the interlayer and avoiding the oxygen and air in the interlayer space reaching the explosion ratio range, resulting in a major safety accident.

[0045] In some other embodiments, the protrusion 24 is rotatably connected to the side wall of the guiding holes in the first guiding ring 211 and the second guiding ring 231, so that the protrusion 24 forms a rolling contact with the outer wall of the guiding rod 22.

[0046] Specifically, the protrusion 24 is a cylindrical roller or a spherical ball, which is connected to the inner side walls of the first guiding ring 211 and the second guiding ring 231 through a rotating shaft and protrudes from the surface of the inner side wall of the guiding ring. When the guiding rod 22 is inserted into the guiding hole, the sliding friction between the guiding rod 22 and the top of the protrusion 24 becomes rolling friction, which can further reduce the friction force on the guiding rod 22, so that the explosion-proof cover 12 can smoothly reciprocate along the set path and will not be stuck.

[0047] Please refer to Figures 1 to 3 , the guiding assembly of this embodiment further includes a limiting plate 25. The limiting plate 25 is arranged at one end of the first guiding rod 221 away from the explosion-proof cover 12, and the limiting plate 25 is used to abut against the first guiding ring 211 to limit the moving stroke of the explosion-proof cover 12.

[0048] Specifically, the limiting plate 25 is arranged at the end of the first guiding rod 221, and the area of the limiting plate 25 is large and cannot pass through the first guiding hole on the first guiding ring 211. When the explosion-proof cover 12 opens the opening of the inner sleeve 11 under the impact of air flow, the explosion-proof cover 12 moves outward along the axis of the first guiding hole. At this time, the limiting plate 25 abuts against the end face of the first guiding ring 211 to limit the explosion-proof cover 12 from continuing to move outward. At this time, the explosion-proof cover 12 reaches the maximum moving stroke.

[0049] In this embodiment, the length of the first guiding ring 211 in the axial direction is longer than the length of the second guiding ring 231 in the axial direction, so that the first guiding ring 211 can bear the abutting pressure of the limiting plate 25 and limit the stroke of the explosion-proof cover 12.

[0050] In this embodiment, when the explosion-proof cover 12 moves to the maximum stroke, that is, when the limit plate 25 abuts against the end face of the first guide ring 211, the free end of the second guide rod 222 on the explosion-proof cover 12 abuts against the bottom wall of the protective cover 13 to further limit the moving stroke of the explosion-proof cover 12.

[0051] Please refer to Figures 1 to 2 , the explosion-proof assembly further includes a locking bolt 14. The locking bolt 14 is movably inserted through the protective cover 13. The locking bolt 14 can move radially along the protective cover 13 so that the end of the locking bolt 14 approaches or moves away from the outer wall of the inner cylinder 11. When the end of the locking bolt 14 approaches and abuts tightly against the outer wall of the inner cylinder 11, the protective cover 13 is fixedly connected to the inner cylinder 11.

[0052] Specifically, a plurality of locking bolts 14 are annularly arranged on the side wall at the bottom of the protective cover 13 in this embodiment. The locking bolt 14 is screwed on the side wall of the protective cover 13 and can move radially along the protective cover 13. When the protective cover 13 is connected to the inner cylinder 11, only need to first buckle the protective cover 13 on the inner cylinder 11, and then rotate the locking bolt 14 on the protective cover 13 to make the locking bolt 14 move radially inward along the protective cover 13, and make the end of the locking bolt 14 abut against the positioning groove on the outer side wall of the inner cylinder 11 to fix the protective cover 13 on the inner cylinder 11.

[0053] By adjusting the radial moving distance of each locking bolt 14 on the protective cover 13, the coaxiality of the protective cover 13 and the inner cylinder 11 can also be adjusted, so that the second guide rod 222 on the explosion-proof cover 12 can be smoothly inserted into the first guide hole of the second guide ring 231 in the protective cover 13, making the installation of the explosion-proof device 100 more convenient.

[0054] This embodiment also provides a heat-insulating container 200, which includes a tank body and the above-mentioned explosion-proof device 100. The tank body includes an outer shell 201, and a pressure relief port is provided on the inclined surface of the outer shell 201, and the pressure relief port penetrates the interlayer space in the tank body. The explosion-proof device 100 is arranged at the pressure relief port for discharging the gas in the interlayer space of the tank body.

[0055] In summary, in this embodiment, by providing a protrusion 24 in the guide hole of the explosion-proof device 100, a point contact is formed between the guide rod 22 and the guide hole, reducing the contact area and also minimizing the friction between the guide rod 22 and the guide hole to the greatest extent. When the explosion-proof device 100 is installed on an inclined surface, the explosion-proof cover 12 can also be smoothly reset under the action of gravity, preventing air from entering the interlayer in the tank body, avoiding the mixture of combustible gas and air in the interlayer space reaching the explosion ratio range, and increasing the safety factor of the heat-insulating container 200. Preventing a large amount of air from entering the interlayer and avoiding the hydrogen and air in the interlayer space reaching the explosion ratio range, its safety performance is better.
