Description

Technical Field

[0001] This utility model relates to the field of radar skeleton technology, and in particular to a phased array radar skeleton. Background Technology

[0002] A phased array radar frame is a structure that provides mechanical support for the various components of a phased array radar antenna, ensuring the accurate and stable relative positions of these components in space and enabling the antenna head to function properly. In existing technologies, phased array radar frames are often welded together from multiple connecting rods, and since they are frequently installed outdoors, the welds on the frame are prone to cracking. This necessitates regular inspections by maintenance personnel to promptly re-weld any cracked welds. The welding process is relatively cumbersome and requires specialized welding equipment, which hinders the ease of maintenance for phased array radar frame personnel. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a phased array radar frame that improves the convenience for maintenance personnel in maintaining the phased array radar frame.

[0004] According to an embodiment of the present invention, a phased array radar skeleton includes a skeleton body, the skeleton body including multiple connecting rods, multiple hub nodes and multiple fixing components; each of the multiple hub nodes is provided with multiple slots, each of the multiple connecting rods is provided with a plug at both ends, the multiple fixing components are respectively provided on the multiple hub nodes, the multiple slots are all used for inserting the plugs, and the fixing components are used to restrict the multiple plugs on the hub nodes from being dislodged from the multiple slots.

[0005] It has at least the following beneficial effects:

[0006] The frame body is composed of multiple connecting rods, all connected by hub joints. Each connecting rod has a plug at both ends, and the hub joints have multiple slots, allowing connecting rods to be inserted and connected. When an installer inserts a plug into a slot, they can manipulate a fixing component to secure the plugs, preventing them from detaching. To assemble the frame body, the installer inserts the plugs into the slots and connects the hub joints and connecting rods sequentially to form the frame body with the predetermined shape. During routine use, if a connecting rod or hub joint becomes damaged or ages, since they are relatively independent components, maintenance personnel can easily remove the damaged plug by manipulating the fixing component. The damaged plug can then be replaced with a new one, completing the frame body maintenance. Compared to traditional phased array radar frames that are welded together, the phased array radar frame of this utility model embodiment does not require the use of professional welding equipment during maintenance, and the replacement of connecting rods and hub nodes in the phased array radar frame is simpler, thereby improving the convenience for maintenance personnel to maintain the phased array radar frame.

[0007] According to the phased array radar skeleton of this utility model embodiment, the hub node is provided with a through hole, and the fixing component includes a first pressure plate, a second pressure plate, a bolt, and a nut. The first pressure plate is provided with a first through hole, and the second pressure plate is provided with a second through hole. The first pressure plate and the second pressure plate abut against both ends of the hub node, so that the first pressure plate can cover one end of the plurality of slots on the hub node, and the second pressure plate can cover the other end of the plurality of slots on the hub node. The bolt passes through the first through hole, the through hole, and the second through hole. The nut is threadedly connected to the bolt. The nut of the bolt and the nut can be pressed tightly on the first pressure plate and the second pressure plate, respectively.

[0008] According to the phased array radar frame of this utility model embodiment, the fixing component further includes an elastic washer, which is sleeved on the bolt, and the nut abuts against the second pressure plate through the elastic washer.

[0009] According to the phased array radar skeleton of this utility model embodiment, one end of the hub node is provided with a first limiting groove, and the first pressure plate is provided with a first limiting block. The first limiting block can be inserted into the first limiting groove to restrict the first pressure plate from rotating around the bolt.

[0010] According to the phased array radar skeleton of this utility model embodiment, the other end of the hub node is provided with a second limiting groove, and the second pressure plate is provided with a second limiting block. The second limiting block can be inserted into the second limiting groove to restrict the second pressure plate from rotating around the bolt.

[0011] According to an embodiment of the present invention, the phased array radar skeleton has a front side for mounting an antenna head and a rear side for providing a first auxiliary frame, which is used to connect to a support structure on the ground.

[0012] According to the phased array radar skeleton of this utility model embodiment, the bottom of the skeleton body is provided with a plurality of second auxiliary frames, and the plurality of second auxiliary frames are all used to connect with the support structure on the ground.

[0027] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, 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.

[0028] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0029] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0030] refer to Figures 1 to 6 This utility model discloses a phased array radar frame, including a frame body 100. The frame body 100 includes multiple connecting rods 110, multiple hub nodes 120, and multiple fixing components 200. Each hub node 120 is provided with multiple slots 121, and each end of the multiple connecting rods 110 is provided with a plug 111. The multiple fixing components 200 are respectively provided on the multiple hub nodes 120. The multiple slots 121 are used for inserting the plugs 111, and the fixing components 200 are used to prevent the multiple plugs 111 on the hub nodes 120 from disengaging from the multiple slots 121.

[0031] It should be explained that in the existing technology, when the connecting rod 110 in the conventionally welded phased array radar frame is damaged, maintenance personnel need to spend a lot of time first breaking the welds at both ends of the connecting rod 110, then removing the damaged connecting rod 110 and re-welding the new connecting rod 110 into place to complete the replacement of the connecting rod 110. This method of replacing the connecting rod 110 by breaking the welds is difficult and time-consuming, and therefore does not improve the convenience of maintaining the frame body 100.

[0032] It is understood that the skeleton body 100 is composed of multiple connecting rods 110, and the multiple connecting rods 110 are connected to each other through hub nodes 120. Each end of the connecting rod 110 is provided with a plug 111, and the hub node 120 has multiple slots 121, all of which can be used to insert the connecting rod 110 to achieve interconnection between the multiple connecting rods 110. When the installer inserts the plug 111 on the connecting rod 110 into the slot 121, the installer can operate the fixing component 200 to restrict the multiple plugs 111 on the hub node 120 to prevent them from coming out of the slots 121. When assembling the skeleton body 100, the installer can insert the plugs 111 on the connecting rod 110 into the slots 121 on the hub node 120, and connect the hub nodes 120 and connecting rods 110 one by one according to the design sequence to gradually form the skeleton body 100 with the preset shape. During routine use of the frame body 100, if a connecting rod 110 or hub node 120 is damaged or aged, since the connecting rod 110 and hub node 120 are relatively independent components, maintenance personnel only need to manipulate the fixing component 200 to disengage the insert 111 on the connecting rod 110 from the fixing component 200. The maintenance personnel can then remove the damaged connecting rod 110 or hub node 120 and replace it with a new one, thus completing the maintenance of the frame body 100. Compared to traditional welded phased array radar frames, the phased array radar frame of this embodiment does not require specialized welding equipment for maintenance, and the replacement method for the connecting rod 110 and hub node 120 in this phased array radar frame is simpler, thereby improving the convenience of maintenance personnel in maintaining the phased array radar frame.

[0033] refer to Figure 3 , Figure 5 and Figure 6Both ends of the connecting rod 110 are flat. Understandably, the flattened ends of the connecting rod 110 facilitate the installation of the inserts 111 on both ends into the slots 121 on the hub node 120, especially in situations with limited space, where the flattened ends allow for more flexible installation in confined spaces. Furthermore, the flattened ends of the connecting rod 110 prevent installation interference between adjacent connecting rods 110.

[0034] refer to Figure 4 and Figure 7 The hub node 120 is provided with a through hole 122. The fixing assembly 200 includes a first pressure plate 210, a second pressure plate 220, a bolt 230 and a nut 240. The first pressure plate 210 is provided with a first through hole, and the second pressure plate 220 is provided with a second through hole. The first pressure plate 210 and the second pressure plate 220 abut against the two ends of the hub node 120, so that the first pressure plate 210 can cover one end of the multiple slots 121 on the hub node 120, and the second pressure plate 220 can cover the other end of the multiple slots 121 on the hub node 120. The bolt 230 passes through the first through hole, the through hole 122 and the second through hole. The nut 240 is threadedly connected to the bolt 230. The nut of the bolt 230 and the nut 240 can be pressed tightly onto the first pressure plate 210 and the second pressure plate 220, respectively. The fixing assembly 200 also includes an elastic washer 250, which is sleeved on the bolt 230, and the nut 240 abuts against the second pressure plate 220 through the elastic washer 250. In this embodiment of the invention, the axis of the hub node 120 coincides with the axis of the through hole 122, and the plurality of slots 121 on the hub node 120 are circumferentially distributed around the axis of the through hole 122. In this invention, the first pressure plate 210 can simultaneously cover one end of the plurality of slots 121 on the hub node 120, and the second pressure plate 220 can simultaneously cover the other end of the plurality of slots 121 on the hub node 120.

[0035] Understandably, after the installer inserts the inserts 111 on one end of the multiple connecting rods 110 into the multiple slots 121 on one of the hub nodes 120, the installer can place the first pressure plate 210 on one end of the hub node 120, so that the first through hole on the first pressure plate 210 aligns with the through hole 122 on the hub node 120. At this time, the first pressure plate 210 simultaneously abuts against the hub node 120 and one end of the multiple inserts 111, and the nut 240 of the bolt 230 abuts against the first pressure plate 210. Next, the installer inserts the bolt 230 into the first through hole on the first pressure plate 210 and the through hole 122 on the hub node 120, and then sequentially fits the second pressure plate 220 and the elastic washer 250 onto the threaded end of the bolt 230, so that the threaded end of the bolt 230 passes through the second through hole on the second pressure plate 220 and the elastic washer 250. Finally, the installer screws the nut 240 onto the threaded end of the bolt 230 and tightens the nut 240. After the nut 240 is tightened, it is pressed against the second pressure plate 220 by the elastic washer 250, and the nut of the bolt 230 is pressed against the first pressure plate 210. Under the action of the nut 240 and the bolt 230, the first pressure plate 210 is pressed against one end of the hub node 120 and the plurality of inserts 111, and the second pressure plate 220 is pressed against the other end of the hub node 120 and the plurality of inserts 111. On the one hand, the first pressure plate 210 and the second pressure plate 220 respectively shield the two ends of the plurality of slots 121, preventing the inserts 111 from disengaging from the slots 121 along the length of the slots 121. On the other hand, the first pressure plate 210 and the second pressure plate 220 clamp and hold the plurality of inserts 111 on the hub node 120, preventing the inserts 111 from disengaging from the slots 121 along the radial direction of the hub node 120. When it is necessary to replace the damaged connecting rod 110 or hub node 120, the maintenance personnel only need to loosen the nut 240 and pull the bolt 230 out of the first through hole, the through hole 122 and the second through hole. At this time, the connecting rod 110 or hub node 120 can be removed, so that the insert 111 on the connecting rod 110 and the slot 121 on the hub node 120 are disengaged, and the disassembly of the connecting rod 110 or hub node 120 can be completed quickly.

[0036] In one embodiment of this utility model, the slot 121 can be a T-shaped slot 121, and the insert 111 can be a T-shaped insert 111. The T-shaped insert 111 can be inserted into the T-shaped slot 121 to prevent the T-shaped insert 111 from disengaging from the T-shaped slot 121 radially along the hub node 120. In another embodiment of this utility model, the two ends of the insert 111 are respectively provided with a third limiting groove and a fourth limiting groove. The first pressing block is provided with a plurality of third limiting blocks, and the second pressing block is provided with a plurality of fourth limiting blocks. The third limiting groove is used for the insertion of the third limiting block, and the fourth limiting block is used for the insertion of the fourth limiting block. Here, the example is given where the insert 111 is inserted into multiple slots 121 on the hub node 120. After the nut 240 is tightened, the third limiting blocks on the first pressure plate 210 are respectively inserted into the third limiting grooves on one end of the multiple inserts 111, and the fourth limiting blocks on the second pressure plate 220 are respectively inserted into the fourth limiting grooves on the other end of the multiple inserts 111. At this time, the corresponding third limiting blocks and fourth limiting blocks restrict the inserts 111, effectively preventing the inserts 111 from disengaging from the slots 121 along the radial direction of the hub node 120.

[0037] It should be explained that, since phased array radar frames are often installed outdoors, they are susceptible to swaying due to wind and rain, which in turn causes the first pressure plate 210 and the second pressure plate 220 to tend to rotate around the bolt 230. When the first pressure plate 210 and the second pressure plate 220 tend to rotate around the bolt 230, the first pressure plate 210 will generate an additional torque on the bolt 230, and the second pressure plate 220 will generate an additional torque on the nut 240, resulting in a reduction in the preload between the bolt 230 and the nut 240, which in turn makes the bolt 230 and the nut 240 prone to loosening. As an embodiment of this utility model, one end of the hub node 120 is provided with a first limiting groove 123, and the first pressure plate 210 is provided with a first limiting block. The first limiting block can be inserted into the first limiting groove 123 to restrict the rotation of the first pressure plate 210 around the bolt 230. The other end of the hub node 120 is provided with a second limiting groove, and the second pressure plate 220 is provided with a second limiting block. The second limiting block can be inserted into the second limiting groove to restrict the second pressure plate 220 from rotating around the bolt 230.

[0038] Understandably, the first limiting block on the first pressure plate 210 can be inserted into the first limiting groove 123 on one end of the hub node 120. The first limiting block can abut against the inner wall of the first limiting groove 123, so that the inner wall of the first limiting groove 123 can limit the first pressure plate 210 through the first limiting block, preventing the first pressure plate 210 from rotating around the axis of the bolt 230, and thus preventing the first pressure plate 210 from applying additional torque to the bolt 230. Similarly, the inner wall of the second limiting groove can limit the second pressure plate 220 through the second limiting block, preventing the second pressure plate 220 from rotating around the axis of the bolt 230, and thus preventing the second pressure plate 220 from applying additional torque to the nut 240. This ensures that the preload of the bolt 230 and the nut 240 will not decrease due to the rotation of the first pressure plate 210 and the second pressure plate 220, thus guaranteeing the connection effect between the bolt 230 and the nut 240.

[0039] refer to Figure 1 and Figure 8 The front side of the frame body 100 is used for mounting the antenna head, and the rear side of the frame body 100 is provided with a first auxiliary frame 130, which is used to connect with the support structure on the ground. The bottom of the frame body 100 is provided with multiple second auxiliary frames 140, all of which are used to connect with the support structure on the ground. In this embodiment of the invention, the frame body 100 is inclined, and the front side of the frame body 100 is a mounting surface, mainly used for mounting various components of the phased array radar antenna. It should be explained that the frame body 100 is mounted on a support structure on the ground. The support structure not only supports and fixes the frame body 100, allowing it to be stably connected to the ground, but also adjusts its attitude, allowing the frame body 100 to be inclined. A first auxiliary frame 130 is connected to the rear side of the skeleton body 100, and a plurality of second auxiliary frames 140 are provided at the bottom of the skeleton body 100. The first auxiliary frame 130 and the second auxiliary frame 140 serve to connect with the support structure on the ground, so that the skeleton body 100 can be installed on the support structure on the ground through the first auxiliary frame 130 and the second auxiliary frame 140.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
