[0002] Space capsules are typically used outdoors and need to withstand rain or other extreme weather. Rainwater can easily seep into the interior of civilian space capsules through the joints of the assembled roof or wall panels, leading to leaks, dampness, and corrosion of the capsule structure. Currently, the assembled panels are tightened with bolts and nuts to improve the fit between the panels, and waterproof adhesives and sealing strips are used in the gaps between the panels to improve the waterproof performance of the assembled components. However, if the waterproof adhesives and sealing strips are not applied evenly or become aged, rainwater can still seep into the gaps between the assembled components. Furthermore, after prolonged use, the width of the gaps between the assembled components increases, further increasing the risk of rainwater infiltration. Utility Model Content

[0022] 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.
[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0024] Example 1:
[0025] Reference Figures 1-4 This utility model provides a sealing and waterproof structure for space capsule panels, including a first connecting plate 1 and a second connecting plate 2, wherein the first connecting plate 1 overlaps the second connecting plate 2, and further includes:
[0026] The first sealing assembly includes a baffle 4, which overlaps the outside of the first connecting plate 1, with one end of the baffle 4 extending out of the end of the first connecting plate 1 and covering the outside of the second connecting plate 2.
[0027] The second sealing assembly is disposed between the first connecting plate 1 and the baffle 4 and between the second connecting plate 2 and the first connecting plate 1. The second sealing assembly is used to seal the gap between the first connecting plate 1 and the baffle 4 and between the second connecting plate 2 and the first connecting plate 1.
[0028] The third sealing assembly includes a sealing groove plate 3 fixedly connected to the inner side of the first connecting plate 1 and the second connecting plate 2. A sealant condition is abutting between the two sealing groove plates 3, and the sealant condition is used to seal the gap between the two sealing groove plates 3.
[0029] The main function of the baffle 4 is to divert rainwater to the side wall of the second connecting plate 2, preventing a large amount of rainwater from flowing to the overlap of the first connecting plate 1 and the second connecting plate 2. The main function of the second sealing assembly is to seal the gaps between the first connecting plate 1 and the second connecting plate 2, as well as the gap between the baffle 4 and the first connecting plate 1, improving the sealing performance at the overlap. The sealing groove plate 3 and the sealant form a water trough structure on the inner side of the first connecting plate 1 and the second connecting plate 2. When water leakage occurs at the overlap of the first connecting plate 1 and the second connecting plate 2, the formed water trough structure can absorb the water, preventing seepage water from entering the spacecraft and ensuring the sealing and waterproof performance. Overall, this utility model effectively improves the waterproof effect of the spacecraft through a triple waterproof structure consisting of rainwater diversion, gap sealing at the overlap, and an internal additional waterproof water trough.
[0030] Further optimization of the scheme: the sealant conditions include a sealant strip 9, and slots 93 are respectively opened inward on the two opposite side walls of the sealant strip 9. The bottom of the two slots 93 respectively abuts against the end of the two sealing plates 3 away from the first connecting plate 1 or the second connecting plate 2.
[0031] like Figure 1 As shown, when the first connecting plate 1 and the second connecting plate 2 overlap, the sealing groove plate 3 is inserted into the slot 93 to automatically form a waterproof water groove structure. The operation is simple and can effectively avoid excessive workload.
[0032] In a further optimized design, the end of the sealing groove plate 3 away from the first connecting plate 1 or the second connecting plate 2 is fixedly connected to an arc end 10, and the sealing groove plate 3 abuts against the slot 93 through the arc end 10.
[0033] like Figure 2 As shown, the arc end 10 can increase the contact area to prevent the sealing groove plate 3 from squeezing and tearing the sealing strip 9, thereby improving the durability and sealing performance of the sealing strip 9.
[0034] In a further optimized design, one end of a connecting strip 92 is fixedly connected to each of the two opposite side walls of the slot 93, and the other end of the connecting strip 92 is fixedly connected to an adhesive strip 91. The two adhesive strips 91 are respectively attached to the two side walls of the sealing groove plate 3.
[0035] The design is further optimized by tilting the connecting strip 92 towards the outside of the slot 93, and setting the side of the fitting strip 91 away from the connecting strip 92 towards the outside of the slot 93.
[0036] like Figure 2 and Figure 3 As shown, in its natural state, by setting the connecting strip 92 and the bonding strip 91 outwards, when the sealing groove plate 3 is inserted into the slot 93, the bonding strip 91 is pushed by the friction of the sealing groove plate 3, causing the connecting strip 92 to deform and the bonding strip 91 to be tightly bonded to the surface of the sealing groove plate 3, thereby further improving the sealing performance.
[0037] The scheme is further optimized by providing a through hole 11 on the baffle 4. The connector 5 passes through the through hole 11, the first connecting plate 1, and the second connecting plate 2 respectively, and fixes the through hole 11, the first connecting plate 1, and the second connecting plate 2 together.
[0038] like Figure 1 As shown, in this embodiment, the connector 5 can be connected using rivets. Before placing the sealing strip 9, the connector 5 is first inserted between the baffle 4, the first connecting plate 1, and the second connecting plate 2.
[0039] In a further optimized design, the second sealing assembly includes a first sealant 6 and a second sealant 7. The first sealant 6 is bonded between the baffle 4 and the first connecting plate 1, and the second sealant 7 is bonded between the first connecting plate 1 and the second connecting plate 2.
[0040] like Figure 1 As shown, the gaps are sealed by applying the first sealant 6 and the second sealant 7 to improve the sealing performance.
[0041] In a further optimized design, a waterproof protrusion 8 is fixedly connected to the outer side of the second connecting plate 2. The waterproof protrusion 8 is located on the inner side of the baffle 4 and close to the first connecting plate 1.
[0042] like Figure 1 As shown, the waterproof protrusion 8 can effectively prevent water from flowing to the joint between the first connecting plate 1 and the second connecting plate 2.
[0043] Example 2:
[0044] The only difference between this embodiment and Embodiment 1 is that the end of the baffle 4 furthest from the through hole 11 is curved upward to form a flange 41. When the baffle 4 is used on the top of the spacecraft, the flange can guide the water flow to both sides.
[0045] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0046] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
