Description

Technical Field

[0001] The present invention relates to the technical field of reflective screens, and specifically to a device for actively tensioning flexible wires, a flexible antenna reflective screen, and an assembly method. Background Art

[0002] The reflection structure of ultra-large fixed short-wave antennas is usually not an ordinary reflector plate, and a flexible reflective screen is usually used to achieve the function of the antenna reflector. The envelope size of large fixed short-wave antennas is huge, and the construction time is usually calculated in months. For rigid frame structures, construction can be carried out in accordance with building codes, and the technical barriers are small. However, for the construction of flexible reflective screens, the building codes often cannot meet the electrical performance requirements of the antenna array surface. To maintain the surface characteristics of the reflective screen to achieve the function of the antenna array, fine copper wires with good elasticity are usually used to make the reflective screen, and prestress is applied to the copper wires during construction to achieve the tensioning of the reflective screen.

[0003] Currently, the prestress of the reflective screen is applied only during installation, and the magnitude of the applied prestress depends solely on experience. The prestress of each reflective wire of the reflective screen cannot maintain good consistency, and the dispersion degree of the prestress values is large. After construction, the arcs of different reflective wires after tensioning are inconsistent, affecting the overall electrical performance of the antenna array.

[0004] Moreover, the prestress can only be applied once during construction and cannot actively adapt to various harsh weather conditions subsequently. If the prestress of some reflective wires is severely lost, the subsequent repair cost is high and the technical difficulty is great.

[0005] In the prior art, the invention patent with the patent publication number CN111170076A discloses a wire pay-off machine, an insulating wire production device, and a wire pay-off method. In the text, when the wire is pulled by an external force and conveyed to the outside of the first support assembly, the angle between the first support rod and the second support rod changes dynamically, so that the distance between the third wire wheel and the second wire wheel changes dynamically with the tension of the wire. The spring makes the angle between the first support rod and the second support rod tend to increase, and further makes the distance between the third wire wheel and the second wire wheel tend to increase, so as to tension the wire. In the prior art, the elastic component is mainly used to alleviate the problem of wire breakage caused by sudden increase in tension. Summary of the Invention

And a wire passing port 216 is left at the combined assembly connection of the upper box body 212 and the lower box body 213, and the end of the flexible wire 1000 passes through the box body 210 through the wire passing port 216.

[0048] In this embodiment, the winding hub 220 includes a central shaft 221, a first spacer 222, a second spacer 223, a third spacer 224, and a prestress adjusting interface 225. The inside of the central shaft 221 is hollow, one end is open, and the other end is closed. The prestress adjusting interface 225 is fixedly connected to the closed end of the central shaft 221. The first spacer 222 is sleeved and fixed at the open end of the central shaft 221 and is flush with the open end of the central shaft 221. The second spacer 223 is sleeved and fixed in the middle of the central shaft 221, and the third spacer 224 is sleeved and fixed at the closed end of the central shaft 221 and is flush with the closed end of the central shaft 221.

Specifically, the wire splitting column is located inside the central shaft 221, and the wire channel 234 faces the first communication hole 226 on the central shaft 221.

[0051] Please refer to Figures 1 to 5As shown, in an embodiment of the present invention, the flexible wire 1000 can be the reflection wire of the antenna reflecting screen. After the reflection wire is wound around the upper winding shaft and the lower winding shaft of the winding hub 220 for a certain number of turns respectively, the splitter 230 is installed into the central shaft 221 to separate the upper and lower coils. The winding hub 220 with the reflection wire is installed into the box body 210 together with the energy storage device 300.

[0058] Embodiment 2

[0059] Please refer to Figures 1 to 7 As shown in Figures 1 to 7 , the present invention also provides a flexible antenna reflecting curtain, including Embodiment 1, as well as meridional reflection lines 510 and zonal reflection lines 520.

[0060] Each reflection line of the reflecting curtain is arranged on a device capable of actively tensioning the flexible line. The second tensioning device 400 of the device stores elastic potential energy through the built-in energy storage device 300, provides a certain prestress adjustment range for the flexible reflection line, reduces the problem of large dispersion of prestress after the reflection line is tensioned, and improves the adaptability to bad weather.

[0061] In this embodiment, according to the operating frequency band of the antenna element and the placement method of the element, the density of the meridional reflection lines 510 and the zonal reflection lines 520 is different. The present invention describes the present invention in the way that the meridional reflection lines 510 are denser and the zonal reflection lines 520 are sparser. The way that the zonal reflection lines 520 are denser and the meridional reflection lines 510 are sparser is regarded as having the same tensioning idea as the present invention. Since the meridional reflection lines 510 are denser, the second tensioning device 400 is only arranged on all the meridional reflection lines 510.

[0062] In this embodiment, the meridional reflection lines 510 are wound around the winding hub 220 in a spiral shape, and the winding direction of the meridional reflection lines 510 is opposite to the spiral direction of the energy storage device 300 through the wire divider 230. The two ends of the meridional reflection lines 510 coming out of the winding hub 220 are respectively fixedly connected to the second tensioning devices 400 oppositely arranged on the side beam. And the two ends of the zonal reflection lines 520 are respectively fixed on the second tensioning devices 400 located on the top beam 140 and the bottom beam 150 for tension adjustment.

[0063] Please refer to Figures 1 to 7 As shown in Figures 1 to 7 , the present invention also provides an assembly method for a flexible antenna reflecting curtain. Still taking the situation where the second tensioning device 400 is only arranged on all the meridional reflection lines 510 as an example for description. The assembly method includes:

[0064] Wind all the meridional reflection lines 510 one by one around each winding hub 220. A wire divider 230 is installed on the winding hub 220. Connect the two ends of the energy storage device 300 to the third spacer 224 and the rear end cover 214 respectively. Install the upper box body 212 onto the lower box body 213. The prestress adjustment interface 225 is located within the pre-tightening protrusion 215 to limit the winding hub 220 and the energy storage device 300. After capping, the assembly of the rear end cover 214 with the meridional reflection lines 510 is completed.

[0065] Assemble the top beam 140, bottom beam 150, first side beam 120, second side beam 130, and middle beam 110 to complete the construction of the frame 100. Install each first tensioning device 200 one by one on the middle beam 110, and install the second tensioning device 400 on the side beams. Fix the two ends of the meridional reflection lines 510 on the first tensioning device 200 to the corresponding second tensioning devices 400 respectively.

[0066] Arrange a wrench with torque measurement function at the prestress adjustment interface 225 of the first tensioning device 200. As the number of rotation turns of the second tensioning device 400 increases, the torque at the prestress adjustment interface 225 gradually increases. When the torque reaches the specified threshold, stop rotating the second tensioning device 400.

[0067] Finally, install the zonal reflection lines 520 on the corresponding second tensioning devices 400. Use a wrench with torque measurement function to screw the second tensioning device 400. When the torque reaches the specified threshold, stop rotating the second tensioning device 400, and the assembly of the flexible reflection screen can be completed.

[0068] Please refer to Figures 1 to 7 As shown, in an embodiment of the present invention, the tension adjustment principle of the actively tensionable flexible reflection screen is as follows: Due to the presence of the first tensioning device 200 and the energy storage device 300, it is equivalent to adding a tension storage device. When the meridional reflection lines are subjected to a large external load, such as wind load, the first tensioning device 200 can store elastic potential energy through the energy storage device 300, release a certain length of the meridional reflection lines, and avoid the occurrence of reflection line damage caused by a sudden increase in reflection line tension. When the external load becomes smaller, the stored elastic potential energy is released, and the reflection lines return to their original length and are automatically tensioned again.
