[0029] The utility model makes further illustration in combination with the drawings. It should be pointed out that the following detailed description of the utility model is only for the purpose of illustration, and is not limiting to the utility model.

[0030] According to the embodiments of the present application, referring to Figures 1 to 4 The metal framework radome node connecting structure can include a mounting column 3 and a rib plate assembly.

[0031] As shown in Figure 1 The mounting column 3 is a regular polygonal prism, and has a plurality of mounting surfaces. One rib plate assembly is mounted on each of the mounting surfaces. The rib plate assembly includes a collection plate 2 and two rib plates 1. The two rib plates 1 are connected to the two side edges of the collection plate 2 that are parallel to the central axis of the mounting column 3. The two rib plates 1 are located on the side of the collection plate 2 that is away from the mounting column 3, and the included angle of the two rib plates 1 is equal to the central angle of the bottom polygon of the regular polygonal prism. The rib plates 1 of adjacent rib plate assemblies are detachably connected. The collection plate 2 and the mounting surface are used to fix the end of the skin that faces the mounting column 3. The rib plates 1 of adjacent rib plate assemblies are used to fix the side of the skin.

[0032] As shown in Figures 1 to 4 Since the central part of the metal framework radome node connecting structure adopts the mounting column 3 in the shape of a regular polygonal prism, each side of the regular polygonal prism is a mounting surface. Each rib plate assembly includes a collection plate 2 and two rib plates 1. During assembly, a number of rib plate assemblies equal to the number of mounting surfaces are assembled first. During installation, only the rib plate assemblies need to be installed on the mounting surfaces of the mounting column, and the rib plates of adjacent rib plate assemblies need to be connected. Since the top of the mounting column is a closed structure, a special collection cover is not needed, thereby greatly simplifying the installation steps of the metal framework radome node connecting structure. Meanwhile, the end of the skin that faces the mounting column can be clamped by the mounting column and the collection plate, and the two sides of the skin can be clamped by the rib plates of adjacent rib plate assemblies, thereby improving the sealing performance of the radome.

[0033] The mounting surfaces of the mounting column 3 are connected to the collection plate 2, and the two bottom surfaces of the mounting column 3 and the two end surfaces of the collection plate 2 are in the same horizontal plane. In the prior art, a separate collection cover is needed to cover the collection plate and the mounting column, which causes the collection cover to protrude from the outer surface of the radome. The radome manufactured according to the metal framework radome node structure of the present application does not have a collection cover, and the outer surface of the radome does not have a protruding structure, thereby making the appearance more beautiful and less likely to accumulate dust and debris.

[0034] As shown in Figure 2As shown, the rib plate 1 is provided with at least two third mounting holes, and the rib plates of two adjacent rib plate assemblies are connected by bolts. The rib plate assembly is connected to the mounting post 3 by bolts.

[0035] like Figure 3 As shown, the assembly plate 2 has a second mounting hole 6. Each assembly plate 2 has a first adhesive groove 5 perpendicular to the center line of the mounting post 3 on its side facing the mounting post 3. A D-shaped sealing strip is disposed in the first adhesive groove 5. There are two first adhesive grooves 5 on each assembly plate 2, and both adhesive grooves are located on the side of the adhesive groove closer to the inside of the antenna cover. The assembly plate 2 has a rectangular groove 4 on its side facing the mounting post 3, and the skin can be inserted into the rectangular groove using a rectangular pressure strip.

[0036] The design employs a rectangular grooved assembly plate, allowing the radome skin to be clamped onto the rectangular groove 4 of the assembly plate 2 via rectangular pressure strips. This results in a more secure connection between the skin and the mounting post, overcoming the problem of gaps between the skin and the mounting post caused by the inability to clamp the skin at cylindrical mounting posts and the lack of sealing measures. This prevents the gaps from widening and the sealing performance from deteriorating due to natural factors such as wind load vibration and solar radiation during subsequent use, thus avoiding the risk of leakage.

[0037] like Figure 4 As shown, the mounting surface of the mounting post 3 has at least two first mounting holes 8, and each mounting surface has a second adhesive recess 7 perpendicular to the center line of the mounting post. A D-shaped sealing strip is disposed within the second adhesive recess 7. The second adhesive recess 7 and the first adhesive recess 7 can be aligned or staggered. When the second adhesive recess 7 and the first adhesive recess 7 are on the same plane, two seals are formed between the mounting post and the assembly plate. When the second adhesive recess 7 and the first adhesive recess 7 are staggered and not on the same plane, four seals are formed between the mounting post and the assembly plate, resulting in better sealing performance.

[0038] In this embodiment, reference Figure 2 As shown, the mounting surface of the mounting column 3 and the assembly plate 2 adopt a combination of multiple adhesive grooves and D-shaped sealing strips. The adhesive grooves on the mounting surface and the assembly plate are set accordingly, and the D-shaped sealing strips are pressed together to enhance the sealing performance. The bolt installation connection makes the installation of the metal frame antenna radome node connection simple and easy to disassemble.

[0039] According to the embodiment of the application, the mounting column is a regular pentagonal prism, and the number of the rib plate assemblies is 5; the sealant strip arranged in the first and second glue setting grooves is a D-shaped sealant strip. In other embodiments, the number of prism edges of the mounting column can also be selected as other numbers, and the number of prism edges is determined by the number of the required mounting rib plate assemblies, and the sealant strip in the glue setting groove can be in other forms, which is not limited in the application.

[0040] The connection process of the metal framework radome node connection structure provided by the application is as follows:

[0041] Step 1, welding two rib plates 1 and one collection plate 2 to form a rib plate assembly;

[0042] Step 2, stretching the skin on the rib plate assembly formed by welding the rib plate 1 and the collection plate 2 through the rectangular pressing strip;

[0043] Step 3, installing a D-shaped sealant strip in the first glue setting groove of the collection plate 2 and the second glue setting groove on the mounting column 3;

[0044] Step 4, stably connecting the rib plate assembly with the stretched skin through the second mounting hole 6 on the collection plate 2 and the first mounting hole 8 on the mounting column 3 by bolts;

[0045] Step 5, connecting the rib plate assemblies through the third mounting holes on each rib plate 1 by bolts;

[0046] Step 6, repeating steps 1-5 according to actual requirements until the radome is formed.

[0047] The rib plate 1 is connected by the collection plate 2, and the skin can be pressed tightly; the center of the metal framework radome node connection structure is the mounting column 3, so that the outer surface of the radome is flush, and there is no external convex structure. The rib plate assemblies are firmly connected, and multiple D-shaped rubber sealant strips are used for sealing and waterproofing to prevent rain and snow erosion.

[0048] The metal framework radome node connection structure is welded with a collection plate and a rib plate, replaces the traditional cylindrical mounting column, and the rectangular groove is opened on the collection plate, so that the skin can be pressed tightly by the rectangular pressing strip, and the gap between the skin and the cylindrical mounting column is solved. Meanwhile, the mounting column is designed, and is directly connected with the collection plate by bolts, and multiple D-shaped rubber sealant strips are installed, so that the structure is simple, the sealing performance is good, and the problems of difficult installation, poor sealing performance and external convexity of the collection cover of the traditional metal framework radome at the node are solved.

[0049] Finally, it should be noted that the features mentioned and / or shown in the above description of the embodiments of the utility model may be combined in the same or similar manner with one or more other embodiments, combined with the features in other embodiments or replace the corresponding features of other embodiments. The technical solutions obtained by combining or replacing should be considered to be within the protection scope of the utility model.
