Description

Technical Field

[0001] This utility model belongs to the field of ground deployment test of multidimensional antennas, and in particular relates to a ground deployment and suspension device for multidimensional satellite antennas. Background Technology

[0002] Antennas are primarily installed on spacecraft such as satellites and spaceships for two-way information transmission between the spacecraft and the ground. Large antennas need to be folded to fit into the rocket fairing, and after satellite launch, the antennas need to be deployed in orbit. While on the ground, the antenna's release, deployment, and locking functions and performance must be verified and tested. The antenna's deployment function and performance after environmental testing, transportation, and satellite assembly must also be verified and tested to ensure the reliability of large antenna deployment in orbit.

[0003] Suspension-type deployment tests are tests in which the tension of the suspension ropes is used to counteract the gravity being compensated during antenna deployment. Based on the movement trajectory of the suspension point, these tests can be divided into one-dimensional deployment tests, two-dimensional deployment tests, and three-dimensional deployment tests. For multi-dimensional deployment antennas, it is necessary to ensure that the deployment paths of different dimensions do not conflict and do not interfere with other onboard equipment. To address this issue, the development of a ground-based deployment suspension device for multi-dimensional satellite antennas is of great significance for ground-based deployment tests and successful on-orbit deployment of antennas. Utility Model Content

[0004] In view of this, the present invention aims to propose a ground deployment and suspension device for multi-dimensional satellite antennas to solve the problem that existing ground deployment tests of multi-dimensional satellite antennas cannot meet the requirements.

The upper end of the trolley assembly is connected to the spring scale of the sail truss. The coil assembly includes a coil and an antenna connection mechanism. The coil has an arc-shaped structure and is slidably connected to the trolley assembly. The antenna connection mechanism is located on the inner side of the end of the coil and is connected to the vertical deployment antenna.

[0006] Furthermore, the trolley assembly includes a trolley suspension mechanism and a trolley. The upper end of the trolley suspension mechanism is connected to the spring scale of the sail truss, and the lower end of the trolley suspension mechanism is connected to the trolley. The coil is slidably connected to the trolley.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention provides a ground-based deployment and suspension device for a multi-dimensional satellite antenna, enabling continuous deployment of the antenna in a one-dimensional horizontal plane and a two-dimensional vertical plane. A spring scale on the sail truss is connected to the suspension device, balancing the device's own weight to simulate the weightless conditions of space. During antenna deployment tests, the horizontally deployable antenna rotates around a horizontal deployment axis, driving the horizontal suspension movement and simultaneously moving the sail truss horizontally. The horizontal suspension ensures that the center of mass of the horizontally deployable antenna remains unaffected by gravity, always within the same horizontal plane. The vertically deployable antenna rotates around a vertical deployment axis, causing the coil assembly to slide on a trolley during deployment. This ensures that the vertically deployable antenna deploys in a two-dimensional vertical plane unaffected by gravity, with the antenna's center of mass always within a single vertical plane.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other, and the described embodiments are only some embodiments of the present invention, not all embodiments.

[0027] See Figure 1-6 This embodiment describes a ground-based deployment and suspension device for a multi-dimensional satellite antenna. The multi-dimensional deployment antenna includes a horizontal deployment antenna 5, a vertical deployment antenna 6, a horizontal deployment shaft 7, and a vertical deployment shaft 8. One end of the horizontal deployment antenna 5 is connected to the horizontal deployment shaft 7, and the other end is connected to the vertical deployment shaft 8. The vertical deployment shaft 8 is connected to the vertical deployment antenna 6. The suspension device includes a horizontal suspension 9, a trolley assembly, and a coil assembly. One end of the horizontal suspension 9 is connected to the horizontal deployment antenna 5, and the other end is mechanically fixed to the spring scale of the sail truss. The upper end of the trolley assembly is mechanically fixed to the spring scale of the sail truss. The coil assembly includes a coil 3 and an antenna connection mechanism 4. The coil 3 has an arc-shaped structure and is slidably connected to the trolley assembly. The antenna connection mechanism 4 is located on the inner side of the end of the coil 3 and is connected to the vertical deployment antenna 6.

[0028] In this embodiment, the trolley assembly includes a trolley suspension mechanism 1 and a trolley 2. The upper end of the trolley suspension mechanism 1 is connected to the spring scale of the sail truss, and the lower end of the trolley suspension mechanism 1 is connected to the trolley 2. The coil 3 is slidably connected to the trolley 2.

[0029] In this embodiment, the trolley suspension mechanism 1 is designed in a U-shape according to the actual interface.

[0030] In this embodiment, the axis of the coil 3 coincides with the axis of the vertical deployment axis 8. The coil 3 is fitted inside the trolley 2, and the coil 3 can rotate around its own central axis within the trolley 2. This allows the multidimensional deployable antenna to deploy in a two-dimensional vertical plane without being affected by gravity, ensuring that the antenna's center of mass remains within a single vertical plane. The horizontal suspension 9 ensures that the center of mass of the horizontally deployable antenna 5 is unaffected by gravity during deployment, always remaining within the same horizontal plane. The trolley 2 is equipped with multiple pulleys to ensure stable sliding.

[0031] In this embodiment, a counterweight 10 is provided on the antenna connection mechanism 4. The size and material of the counterweight 10 are determined according to the weight of the multidimensional deployable antenna. Multiple counterweights 10 can also be stacked to ensure that the overall center of gravity of the multidimensional deployable antenna is located at the suspension point after it is deployed in the horizontal plane.

[0032] In this embodiment, the horizontally deployable antenna 5 is provided with horizontally oriented hanging holes, and the horizontally oriented hanging device 9 is mechanically connected to the horizontally deployable antenna 5 through the horizontally oriented hanging holes. The horizontally oriented hanging device 9 is designed according to the spacing of the horizontally oriented hanging holes. The vertically deployable antenna 6 is provided with vertically oriented hanging holes, and the antenna connecting mechanism 4 is mechanically connected to the vertically deployable antenna 6 through the vertically oriented hanging holes. The antenna connecting mechanism 4 is designed according to the spacing of the vertically oriented hanging holes.

[0033] In this implementation, the spring scale of the sail truss is connected to the suspension device, which can balance the weight of the suspension device itself to simulate the weightless situation in space. During the antenna deployment test, the horizontally deployable antenna 5 rotates around the horizontal deployment axis 7, driving the horizontal suspension 9 to move, which in turn drives the sail truss to move horizontally. The horizontal suspension 9 ensures that the center of mass of the horizontally deployable antenna 5 is not affected by gravity when it is deployed, and it always remains in the same horizontal plane. The vertically deployable antenna 6 rotates around the vertical deployment axis 8. When the vertically deployable antenna 6 is deployed, it drives the coil assembly to slide on the trolley 2, so that the vertically deployable antenna 6 is not affected by gravity and unfolds in a two-dimensional vertical plane, and the center of mass of the antenna always remains in a vertical plane.

These specific embodiments do not exhaustively describe all details, nor do they limit the utility model to only the described embodiments. Many modifications and variations can be made based on the content of this specification.
