For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0043] like Figures 1 to 20 As shown, a high-altitude oxygen chamber includes an oxygen chamber body assembly 1, a sealing plate assembly 5, and a door sealing plate assembly 6.

[0044] The oxygen chamber assembly 1 is a chamber structure with an opening at the front and rear and an internal space for accommodating the contents. It includes a bottom plate assembly 2, a side plate assembly 3, and a top plate assembly 4. Both ends of the bottom plate assembly 2 in the width direction are provided with a set of side plate assemblies 3 vertically. The lower ends of the side plate assemblies 3 are connected to the ends of the bottom plate assembly 2 by welding. The top plate assembly 4 is provided at the upper end of the two sets of side plate assemblies 3. The ends of the top plate assembly 4 in the width direction are connected to the upper ends of the side plate assemblies 3 by welding. The bottom plate assembly 2, the side plate assembly 3, and the top plate assembly 4 together form the oxygen chamber assembly 1.

[0045] The sealing plate assembly 5 is welded to the rear opening of the oxygen chamber body assembly 1 to seal the rear opening. The door sealing plate assembly 6 is welded to the front opening of the oxygen chamber body assembly 1 to seal the front opening. The door sealing plate assembly 6 has a door opening 25 for installing a door to facilitate personnel entry and exit.

[0046] The base plate assembly 2, side plate assembly 3, top plate assembly 4, sealing plate assembly 5, and door sealing plate assembly 6 each include at least two sets of support plates 7, wherein the support plates 7 are as follows: Figure 6 As shown, it includes an upper panel 8, a lower panel 9, a first vertical rib 10, a second vertical rib 11, a first connecting protrusion 12, and a second connecting protrusion 13.

[0047] The upper panel 8 and the lower panel 9 are arranged at intervals and remain relatively parallel. A first vertical rib 10 and a second vertical rib 11 are provided between the upper panel 8 and the lower panel 9. The first vertical rib 10 is located on the left side of the upper panel 8 or the lower panel 9, but not at the end of the left side of the upper panel 8 or the lower panel 9, so that the upper panel 8, the lower panel 9, and the first vertical rib 10 together form a groove structure with an opening at the left end.

[0048] The second vertical rib 11 is located on the right side of the upper panel 8 or the lower panel 9, and is at the end of the right side of the upper panel 8 or the lower panel 9. The right side surface of the second vertical rib 11 is provided with a first connecting protrusion 12 and a second connecting protrusion 13. The first connecting protrusion 12 is located above the second connecting protrusion 13, and the right end of the first connecting protrusion 12 has an upwardly extending curved edge, and the right end of the second connecting protrusion 13 has a downwardly extending curved edge.

[0049] The two adjacent sets of support plates 7 are spliced ​​together. Specifically, the first connecting protrusion 12 and the second connecting protrusion 13 at the right end of the left support plate 7 are inserted into the groove at the left end of the right support plate 7. The right-hand bend of the first connecting protrusion 12 abuts against the lower surface of the upper panel 8 of the right support plate 7, and the right-hand bend of the second connecting protrusion 13 abuts against the upper surface of the lower panel 9 of the right support plate 7. The arrangement of the first connecting protrusion 12 and the second connecting protrusion 13 ensures that the upper panel 8 and the lower panel 9 are flush after the two adjacent sets of support plates 7 are spliced ​​together. In this state, the ends of the upper panels 8 and the ends of the lower panels 9 of the two adjacent support plates 7 are welded together to achieve the purpose of fixing the two sets of support plates 7 together.

[0050] The support plate 7 has reinforcing ribs 14 in the area between the upper panel 8, lower panel 9, first vertical rib 10, and second vertical rib 11, which can further improve the overall structural strength of the support plate 7.

[0051] The upper panel 8 and lower panel 9 can be flat or curved. For example, in the bottom plate assembly 2 of the oxygen chamber, the upper panel 8 and lower panel 9 of the support plate 7 in the middle position are both flat. The support plates 7 at the left and right ends of the bottom plate assembly 2 are both L-shaped, so that the upper panel 8 and lower panel 9 are L-shaped and can be adapted to the structural design at the corner of the chamber assembly.

[0052] The aforementioned support plate 7 is made of aluminum alloy, and the upper panel 8, lower panel 9, reinforcing rib 14, first vertical rib 10, and second vertical rib 11 are integrally extruded using an extrusion process. Compared with traditional steel high-altitude oxygen chambers, the number of welds can be significantly reduced under the same structure, which can avoid the risk of weld cracks caused by bumps during transportation.

[0053] With the above configuration, the oxygen chamber body assembly 1, the sealing plate assembly 5, and the door sealing plate assembly 6 are all double-layered structures. After mechanical performance testing, their internal pressure bearing capacity can reach 50 kPa, effectively improving the internal pressure bearing capacity of the high-altitude oxygen chamber body structure.

[0054] In the above technical solution, since the bottom plate assembly 2, the side plate assembly 3, and the top plate assembly 4 are all composed of support plates 7, the connection method between the bottom plate assembly 2 and the side plate assembly 3, and the connection method between the top plate assembly 4 and the side plate assembly 3 are the same as the connection method between two adjacent support plates 7, thus realizing the assembly of the oxygen chamber body assembly 1.

[0055] As a supplement to the technical solution of this utility model, the support plate 7 also includes a thermal insulation filling layer 15, a circular rib 16, and a thermal insulation isolation plate 17.

[0056] The reinforcing ribs 14 of the support plate 7 divide the space enclosed by the upper panel 8, lower panel 9, first vertical rib 10, second vertical rib 11, and reinforcing ribs 14 into several independent areas, and each independent area is provided with a thermal insulation filling layer 15.

[0057] The first vertical rib 10 and the second vertical rib 11 of the support plate 7 are each provided with a circular rib 16 on the side surface near the reinforcing rib 14. The circular rib 16 is also integrally extruded with the first vertical rib 10, the second vertical rib 11, and other structures using an extrusion process. The end of the circular rib 16 in the longitudinal direction is provided with a threaded hole. The lengths of the first vertical rib 10, the second vertical rib 11, the circular rib 16, and the reinforcing rib 14 are all less than the lengths of the upper panel 8 and the lower panel 9, which is achieved by shortening the lengths of the first vertical rib 10, the second vertical rib 11, and the reinforcing rib 14 through processing after extrusion. The thermal insulation plate 17 is located between the upper panel 8 and the lower panel 9 and is connected to the circular rib 16 by screwing. The thermal insulation plate 17 further improves the thermal insulation effect.

[0058] Since the base plate assembly 2, side plate assembly 3, top plate assembly 4, sealing plate assembly 5, and door sealing plate assembly 6 can be assembled from multiple sets of support plates 7, to facilitate the assembly of the thermal insulation isolation plate 17, a set of thermal insulation isolation plates 17 is provided at the front and rear ends of the base plate assembly 2, side plate assembly 3, and top plate assembly 4. This replaces the method of providing a set of thermal insulation isolation plates 17 on each set of support plates 7 and then welding the ends of adjacent sets of thermal insulation isolation plates 17, thus improving the ease of installation. The thermal insulation isolation plates 17 at the front end of the base plate assembly 2, side plate assembly 3, top plate assembly 4, and sealing plate assembly 5 are on the same vertical plane, and the thermal insulation isolation plates 17 at the rear end are also on the same vertical plane.

[0059] Correspondingly, a set of thermal insulation isolation plates 17 are provided at the upper and lower ends of the sealing plate assembly 5 and the door sealing plate assembly 6.

[0060] The shape of the thermal insulation isolation panel 17 can be adaptively adjusted according to the actual situation so that it can adapt to the shape of the bottom plate assembly 2, side plate assembly 3, top plate assembly 4, sealing plate assembly 5, and door sealing plate assembly 6.

[0061] As a preferred embodiment of the present invention, both sets of side plate assemblies 3 are provided with observation holes 18, and a first welding seal ring 19 is welded to the side plate assembly 3 at the outer periphery of the observation holes 18. The sealing performance of the side plate assembly 3 is ensured by the setting of the first sealing ring.

[0062] As a preferred embodiment of the present invention, a manhole 20 is provided on the top plate assembly 4, and a second welding seal ring 21 is welded to the outer periphery of the manhole 20 on the top plate assembly 4. The second welding seal ring 21 ensures the sealing performance of the top plate assembly 4.

[0063] As a preferred embodiment of this invention, the system further includes a cabin support assembly 22. The cabin support assembly 22 is a ring-shaped structure disposed within the oxygen chamber cabin assembly 1 and located at the openings at both the front and rear ends of the oxygen chamber cabin assembly 1. It provides support at these openings, thereby improving the structural stability of the oxygen chamber cabin assembly 1. The shape of the cabin support assembly 22 is the same as the cross-sectional shape of the oxygen chamber cabin assembly 1.

[0064] The cabin support assembly 22 is connected to the bottom plate assembly 2, the top plate assembly 4, and the side plate assembly 3 by welding.

[0065] As a preferred technical solution of this utility model, the cabin support assembly 22 is composed of several profiles with right-angled triangular cross sections welded end to end; the profiles constituting the cabin support assembly 22 have a first right-angled side and a second right-angled side, wherein the first right-angled side is welded to the bottom plate assembly 2, the side plate assembly 3 or the top plate assembly 4; the second right-angled side is located on the side of the first right-angled side near the opening end of the oxygen chamber cabin assembly 1.

[0066] The load-bearing capacity of the cabin support assembly 22 can be increased by splicing together profiles with right-angled triangular cross sections.

[0067] As a preferred technical solution of this utility model, the sealing plate assembly 5 and the door sealing plate assembly 6 are respectively inserted into the front and rear openings of the oxygen chamber body assembly 1, and are connected to the oxygen chamber body assembly 1 and the body support assembly 22 by welding.

[0068] The second right-angled side of the profile that makes up the cabin support assembly 22 can improve the installation accuracy of the sealing plate assembly 5 and the door sealing plate assembly 6 and increase the contact area with the sealing plate assembly 5 and the door sealing plate assembly 6, thus ensuring the stability of the welded structure.

[0069] As a preferred technical solution of this utility model, it also includes an edge sealing assembly 23, which has two sets and is respectively disposed at both ends of the oxygen chamber body assembly 1. The edge sealing assembly 23 is a ring structure, and the shape of the edge sealing assembly 23 is the same as the cross-sectional shape of the oxygen chamber body assembly 1. The edge sealing assembly 23 is composed of several sets of aluminum alloy square bars welded end to end. The inner sidewall of the edge sealing assembly 23 is provided with a limiting protrusion 24, which contacts the end face of the sealing plate assembly 5 and the door sealing plate assembly 6 on the side away from the body support assembly 22, and is connected to the sealing plate assembly 5 and the door sealing plate assembly 6 by welding.

[0070] By setting the edge sealing assembly 23, on the one hand, the end of the support plate 7 of the oxygen chamber body assembly 1 can be further sealed to improve the thermal insulation performance; on the other hand, the sealing plate assembly 5 and the door sealing plate assembly 6 can be further limited and fixed to improve the structural stability of the entire plateau oxygen chamber.

[0071] The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be included within the protection scope of the present invention.
