Description

Technical Field

[0001] This utility model belongs to the field of radio frequency simulation system technology, and more specifically, it relates to a spherical screen support structure system. Background Technology

[0002] Radio frequency (RF) simulation systems simulate the combat environment in a laboratory setting, thereby simulating the electromagnetic environment required for various radar tests and dynamically evaluating the tested equipment. In practical engineering applications, RF simulation systems typically use a three-element antenna array to simulate the target's trajectory relative to the tested equipment in space. The positional accuracy of the three-element antenna elements is a crucial factor affecting the performance of the simulation system.

[0003] Because RF simulation requires using the varying amplitudes of three antennas to simulate the movement of a target point inside a triangle, the distances of the three antennas from the turntable center must be equal. The antenna apertures of the triplet antenna array must be on a spherical surface; that is, the support structure of the triplet antenna array must ensure that the antenna elements are mounted on the same spherical surface, with each antenna on a spherical surface of equal radius. However, RF simulations typically involve a large number of antennas, and each horn antenna requires high installation accuracy. Ensuring that hundreds or thousands of horn antennas simultaneously meet the positional accuracy requirements is extremely difficult, and the installation stability is hard to guarantee.

[0010] In one possible implementation, the load-bearing structure further includes an annular rod fixedly connected to the support frame, wherein the projections of the plurality of horizontal support rods, the plurality of inclined support rods, the plurality of first mounting cylinders, and the plurality of triangular plates in the direction of the annular rod are all located within the annular rod; the ends of the outer horizontal support rods and the inclined support rods, and the sides of the outer triangular plates are all fixedly connected to the inner wall of the annular rod.

[0011] In one possible implementation, the support frame includes multiple vertical frames, two upper inclined support beams, and two lower inclined support beams. The multiple vertical frames are arranged in an arc-shaped interval around the spherical screen. The multiple vertical frames, the two upper inclined support beams, and the two lower inclined support beams form an installation cavity for installing the load-bearing structure.

[0012] In one possible implementation, the vertical frame is fixed with a plurality of interlayer support rods arranged at vertical intervals.

[0013] In one possible implementation, the spherical screen support structure system further includes a vibration isolation foundation, wherein the vibration isolation foundation is provided with vibration isolation zones corresponding to the support frame and the load-bearing structure respectively, and the lower ends of the support frame and the load-bearing structure are installed in the corresponding vibration isolation zones.

[0014] In one possible implementation, the spherical screen support structure system further includes a wave-absorbing material for covering the front of the spherical screen to reduce electromagnetic interference.

[0015] The beneficial effects of the spherical screen support structure system provided by this utility model are as follows: Compared with the prior art, the spherical screen support structure system of this utility model, in specific operation, firstly requires determining the installation position and arc radius of the support frame according to the overall layout of the RF simulation system and the size of the spherical screen, ensuring that the support frame can stably surround the spherical screen after vertical installation, laying the foundation for subsequent structural installation; then, the load-bearing structure is precisely installed on the support frame, and the center position of the convex spherical surface of the load-bearing structure must be strictly calibrated during installation to ensure that it is consistent with the spherical center required for RF simulation; subsequently, according to the requirement of uniform distribution in a plum blossom pattern, multiple first mounting cylinders are installed on the other side of the load-bearing structure, while ensuring that the central axes of all first mounting cylinders are accurately converged at the center of the convex spherical surface, avoiding the impact of installation deviation on the antenna position accuracy; at the same time, horizontal support rods and diagonal support rods are installed so that the three adjacent first mounting cylinders, one horizontal support rod and two diagonal support rods arranged in a triangle form a complete ternary support component.

During installation, the connection between the antenna and the mounting cylinder must be checked to prevent loosening during subsequent use. In this way, by arranging multiple first mounting cylinders, the structure ensures that all microwave antenna elements can be stably mounted on the same spherical surface. Even when facing the installation requirements of hundreds or thousands of horn antennas, the positional accuracy of each antenna can be effectively controlled, significantly improving the performance and accuracy of the simulation system. On the other hand, the three-element support components composed of horizontal and diagonal support rods form a multi-dimensional and stable support system. This not only enhances the stability of the installation position of individual antennas, but also improves the deformation resistance of the entire support system through the mutual support of adjacent structures, ensuring the long-term stable operation of the RF simulation system.

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] Please see Figures 1 to 6 The spherical screen support structure system provided by this utility model will now be described. A spherical screen support structure system includes a support frame 2, a load-bearing structure 1, horizontal support rods 1-3, and inclined support rods 1-4. The support frame 2 is vertically arranged and arc-shaped around the spherical screen. The load-bearing structure 1 is mounted on the support frame 2. One side of the load-bearing structure 1 is a protruding spherical surface for mounting the spherical screen, and the other side has multiple first mounting cylinders 1-1 evenly arranged in a quincunx pattern, with the central axes of the multiple first mounting cylinders 1-1 converging at the center of the protruding spherical surface. A microwave antenna unit is fixedly connected to the first mounting cylinders 1-1. The horizontal support rods 1-3... There are multiple first mounting cylinders 1-1, which are installed between two adjacent first mounting cylinders 1-1 located on the same horizontal plane; the two ends of the horizontal support rod 1-3 are fixedly connected to the two first mounting cylinders 1-1; there are multiple diagonal support rods 1-4, which are installed between two adjacent first mounting cylinders 1-1 arranged vertically and in an alternating manner; the two ends of the diagonal support rod 1-4 are fixedly connected to the two first mounting cylinders 1-1; the three first mounting cylinders 1-1, one horizontal support rod 1-3 and two diagonal support rods 1-4 arranged in a triangle form a ternary support component.

[0024] The spherical screen support structure system provided by this utility model, compared with the prior art, constructs a precise and stable antenna installation foundation by rationally designing the connection relationship between the support frame 2, the load-bearing structure 1, the horizontal support rod 1-3, and the inclined support rod 1-4. The support frame 2 is vertically arranged and arc-shaped around the spherical screen, providing a stable support framework for the overall structure and ensuring that it is not prone to displacement during subsequent installation and use. The load-bearing structure 1 is installed on the support frame 2. A protruding spherical surface on one side provides an installation reference surface for the antenna that meets the requirement of the same spherical surface. On the other side, multiple first mounting cylinders 1-1 are evenly arranged in a quincunx pattern. This not only achieves the orderly installation of microwave antenna units, but more importantly, the central axes of the multiple first mounting cylinders 1-1 converge at the center of the protruding spherical surface, fundamentally ensuring that each microwave antenna unit installed on the first mounting cylinder 1-1 is precisely positioned on the same spherical surface, perfectly meeting the requirement in RF simulation that the three antennas are equidistant from the center of the turntable.

[0025] In practical operation, firstly, based on the overall layout of the RF simulation system and the size of the spherical screen, the installation position and curvature of the support frame 2 must be determined to ensure that the support frame 2 can stably surround the spherical screen after vertical installation, laying the foundation for subsequent structural installation. Next, the load-bearing structure 1 is precisely installed on the support frame 2. During installation, the center position of the load-bearing structure 1 protruding from the spherical surface must be strictly calibrated to ensure it aligns with the spherical center required for RF simulation. Subsequently, following a quincunx-shaped uniform distribution, multiple first mounting cylinders 1-1 are installed on the other side of the load-bearing structure 1, ensuring that the central axes of all first mounting cylinders 1-1 accurately converge at the center of the protruding spherical surface to avoid affecting antenna position accuracy due to installation deviations. Simultaneously, horizontal support rods 1-3 and diagonal support rods 1-4 are installed, forming a complete ternary support structure with three adjacent first mounting cylinders 1-1 arranged in a triangle, one horizontal support rod 1-3, and two diagonal support rods 1-4. Finally, the microwave antenna elements are fixedly connected one by one to the first mounting cylinders 1-1. During installation, the connection between the antenna and the mounting cylinder must be checked for firmness to prevent loosening during subsequent use. In this way, by arranging multiple first mounting cylinders 1-1, the structure ensures that all microwave antenna units can be stably installed on the same spherical surface. Even when facing the installation requirements of hundreds or thousands of horn antennas, the positional accuracy of each antenna can be effectively controlled, greatly improving the performance and accuracy of the simulation system. On the other hand, the three-element support components composed of horizontal support rods 1-3 and diagonal support rods 1-4 form a multi-dimensional and stable support system. This not only enhances the stability of the installation position of individual antennas, but also improves the deformation resistance of the entire support system through the mutual support of adjacent structures, ensuring the long-term stable operation of the RF simulation system.

[0026] Please see Figures 1 to 4 In one specific embodiment of the spherical screen support structure system provided by this utility model, a connecting cylinder 1-2 is sleeved on the outer side of the first mounting cylinder 1-1, and the ends of the horizontal support rod 1-3 and the inclined support rod 1-4 are fixedly connected to the connecting cylinder 1-2. The connecting cylinder 1-2 constructs a transitional connection structure, avoiding direct connection between the horizontal support rod 1-3, the inclined support rod 1-4 and the first mounting cylinder 1-1. This retains the stable installation function of the first mounting cylinder 1-1 for the antenna while providing an independent and suitable connection carrier for the horizontal support rod 1-3 and the inclined support rod 1-4. The connecting cylinder 1-2 can disperse the force transmitted by the support rods, avoiding stress concentration in a localized area of ​​the first mounting cylinder 1-1 and reducing the risk of component damage.

[0027] Please see Figure 3As a specific embodiment of the spherical screen support structure system provided by this utility model, the connecting cylinder 1-2 is provided with several connecting holes, and the first mounting cylinder 1-1 is provided with several through holes coaxially aligned with the connecting holes. The connecting cylinder 1-2 is provided with fasteners 1-5 that are detachably connected to the first mounting cylinder 1-1. The structure of the connecting cylinder 1-2 and the first mounting cylinder 1-1 is further optimized by using a combination of connecting holes, through holes, and detachable fasteners 1-5 to achieve a precise and flexible connection between the two. The several connecting holes on the connecting cylinder 1-2 are coaxially aligned with the through holes of the first mounting cylinder 1-1, providing a precise positioning reference for the installation of fasteners 1-5 and ensuring that there is no radial offset between the two during connection. The setting of detachable fasteners 1-5 breaks the limitation of fixed connection, making the assembly and disassembly of the connecting cylinder 1-2 and the first mounting cylinder 1-1 more convenient. With the help of the coaxial alignment hole design, the coaxiality of the connecting cylinder 1-2 and the first mounting cylinder 1-1 can be guaranteed after assembly, avoiding the antenna installation position shift due to connection deviation, and further consolidating the accuracy requirements of the antenna on the same spherical surface; at the same time, the detachable connection method greatly reduces the difficulty of later maintenance. When the connecting cylinder 1-2, support rod or the first mounting cylinder 1-1 is damaged, there is no need to destroy the overall structure. Only the fastener 1-5 needs to be removed to replace the parts.

[0028] Please see Figure 2 and Figure 3 As a specific embodiment of the spherical screen support structure system provided by this utility model, a flange is provided at the end of the first mounting cylinder 1-1, and the microwave antenna unit is connected to the flange. Utilizing the planar connection characteristics of the flange, a stable and precise connection structure is constructed between the antenna and the mounting cylinder. The flange provides a large contact area and a regular connection reference, ensuring that the antenna can be precisely aligned with the central axis of the first mounting cylinder 1-1 during installation. The multi-bolt hole design of the flange enables multi-point fixing, significantly improving the robustness of the connection between the antenna and the mounting cylinder, and preventing the antenna from loosening or shifting due to vibration or other factors during long-term use. Simultaneously, the standardized connection form of the flange can adapt to different models of microwave antenna units, reducing the difficulty of antenna replacement and adaptation.

[0029] Please see Figure 1 and Figure 2As a specific embodiment of the spherical screen support structure system provided by this utility model, the supporting structure 1 also includes multiple triangular plates 1-6, each corresponding to a multiple ternary support member, and fixedly connected to the horizontal support rod 1-3 and the inclined support rod 1-4. Several second mounting cylinders 1-7 for mounting millimeter-wave antenna units are provided on the triangular plates 1-6. By adding triangular plates 1-6 corresponding to the ternary support members to the supporting structure 1, and fixing the triangular plates 1-6 to the horizontal support rod 1-3 and the inclined support rod 1-4, while providing several second mounting cylinders 1-7 for mounting millimeter-wave antenna units, a dual design of support reinforcement and functional expansion is achieved. The precise correspondence between the triangular plates 1-6 and the ternary support members allows for coordinated support with the horizontal support rod 1-3 and the inclined support rod 1-4, further strengthening the stability of the ternary structure. The second mounting cylinders 1-7 allow the supporting structure 1 to additionally mount millimeter-wave antenna units in addition to the microwave antenna units. The triangular plate 1-6 can disperse the stress transmitted by the horizontal and inclined support rods 1-4, preventing damage due to stress concentration at the connection between the support rod and the first mounting cylinder 1-1, and improving the overall structure's resistance to deformation. In addition, the millimeter-wave antenna unit can be installed without the need for an additional support frame, saving structural space and manufacturing costs. Furthermore, the setting of the second mounting cylinder 1-7 can ensure the installation accuracy of the millimeter-wave antenna unit, and together with the microwave antenna unit, it can meet the needs of RF simulation for multiple types of antennas.

[0030] Meanwhile, the horizontal support rod 1-3 and the diagonal support rod 1-4 serve as the positioning reference for the triangular plate 1-6, ensuring the accurate physical position of the triangular plate 1-6, thereby guaranteeing the installation position accuracy requirements of the second mounting cylinder 1-7 and the millimeter-wave antenna unit. The triangular plate 1-6 is made of steel plate.

[0031] Please see Figure 1 and Figure 4As a specific embodiment of the spherical screen support structure system provided by this utility model, the load-bearing structure 1 also includes an annular rod fixedly connected to the support frame 2. The projections of multiple horizontal support rods 1-3, multiple inclined support rods 1-4, multiple first mounting cylinders 1-1, and multiple triangular plates 1-6 in the direction of the annular rod are all located inside the annular rod. The ends of the outer horizontal support rods 1-3 and inclined support rods 1-4, and the sides of the outer triangular plates 1-6 are all fixedly connected to the inner wall of the annular rod. The annular rod forms a whole with multiple horizontal support rods 1-3, multiple inclined support rods 1-4, multiple first mounting cylinders 1-1, and multiple triangular plates 1-6. On the one hand, the annular rod serves as an additional connection point between the load-bearing structure 1 and the support frame 2, strengthening the correlation between the overall structure and the support frame 2. On the other hand, by fixing it to the horizontal support rods 1-3, inclined support rods 1-4, and triangular plates 1-6, the dispersed components are integrated into a unified force-bearing system, avoiding the displacement of local structures due to independent forces. This structure significantly improves the overall stability and anti-interference capability of the support structure. Even when faced with high-frequency vibration or external impact, the linkage of the ring rods can maintain the positional accuracy of each component, ensuring that the antenna is always on the same spherical surface.

[0032] Please see Figure 1 and Figure 4 As a specific embodiment of the spherical screen support structure system provided by this utility model, the support frame 2 includes multiple vertical frames, two upper inclined support beams 2-2 and two lower inclined support beams 2-3. The multiple vertical frames are arranged in an arc-shaped interval around the spherical screen. The multiple vertical frames, the two upper inclined support beams 2-2 and the two lower inclined support beams 2-3 form an installation cavity for installing the load-bearing structure 1. The support frame 2 is composed of multiple vertical frames, two upper inclined support beams 2-2 and two lower inclined support beams 2-3. The precise combination of components forms a regular installation cavity. The multiple vertical frames are arranged in an arc-shaped interval around the spherical screen to provide a vertical support foundation for the structure. The two upper inclined support beams 2-2 and the two lower inclined support beams 2-3 are connected to the vertical frames from the upper and lower parts respectively, and together form a closed installation space for installing the load-bearing structure 1. This not only matches the arc-shaped contour of the spherical screen, but also provides a fixed and suitable installation area for the load-bearing structure 1. In this way, on the one hand, the vertical frames arranged in arc intervals can fit the shape of the spherical screen, avoiding spatial interference between the support structure and the spherical screen, while dispersing the vertical load; on the other hand, the symmetrical arrangement of the upper and lower diagonal support beams 2-3 can reinforce the vertical frames from the horizontal and diagonal directions, forming a three-dimensional support system that greatly improves the deformation resistance of the support frame 2.

[0033] Please see Figure 1 and Figure 4As a specific embodiment of the spherical screen support structure system provided by this utility model, a plurality of interlayer support rods 2-1 arranged vertically and horizontally are fixed inside the vertical frame. By adding a plurality of interlayer support rods 2-1 in the vertical structure, the interlayer support rods 2-1 can effectively disperse the longitudinal pressure borne by the vertical frame, and prevent the vertical frame from bending or deforming in the middle due to its high height and large load. At the same time, the vertically and horizontally spaced design can flexibly adjust the spacing according to the height of the vertical frame and the load-bearing requirements, ensuring uniform support strength at different positions and improving the overall lateral bending resistance of the vertical frame.

[0034] Please see Figure 1 , Figures 4 to 6 As a specific embodiment of the spherical screen support structure system provided by this utility model, the spherical screen support structure system also includes a vibration isolation foundation 3. The vibration isolation foundation 3 has vibration isolation zones corresponding to the support frame 2 and the load-bearing structure 1, respectively. The lower ends of the support frame 2 and the load-bearing structure 1 are installed in their respective vibration isolation zones. By using the vibration isolation foundation 3 to isolate the foundation, vibrations transmitted from the ground or external environment can be effectively absorbed, preventing vibrations from being transmitted to the antenna unit through the support frame 2 and the load-bearing structure 1, thereby avoiding affecting the positioning accuracy of the target antenna on the spherical screen. The vibration isolation zones are filled with buffer material to effectively absorb vibration energy.

[0035] Please see Figure 5 and Figure 6 As a specific embodiment of the spherical screen support structure system provided by this utility model, the spherical screen support structure system also includes a wave-absorbing material 4 for covering the front of the spherical screen to reduce electromagnetic interference. The full-coverage design of the wave-absorbing material 4 ensures that there are no interference dead angles on the front of the spherical screen, blocking the influence of clutter from the propagation path. The wave-absorbing material 4 can efficiently absorb electromagnetic waves reflected from the surface of the spherical screen and stray electromagnetic waves in the external environment, preventing these interference waves from superimposing on the simulated signals emitted by the antenna unit, preventing distortion of the simulated electromagnetic environment, thereby reducing electromagnetic interference to the central area of ​​the turntable and ensuring the accuracy of the test. After implementation, it can significantly improve the signal purity of the radio frequency simulation system, ensuring that the tested equipment receives accurate target simulated signals and guaranteeing the accuracy of dynamic evaluation results; at the same time, it reduces the impact of electromagnetic interference on the performance of the antenna unit and avoids interference causing antenna instability.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
