Problems solved by technology

[0003] The purpose of the present invention is to provide a double-layer frame type in-orbit repairable inflatable solar panel to solve the problem that astronauts need to walk in the space environment when some of the solar panels or battery substrates are damaged or aging when the solar panel is in orbit. It takes a long distance to replace the damaged or aging solar panels as a whole, which causes a waste of resources and poses a threat to the safety of astronauts.

specific Embodiment approach 1

[0007] Specific implementation mode one: combine Figure 1 to Figure 7 Explain that the inflatable and unfolded solar panel of this embodiment includes a double-layer inflatable unfolding frame and a plurality of solar cell substrates 1; the double-layer inflatable unfolding frame includes a support shaft 2, four support tubes 3, two support horizontal plates 4, Four wires 5, eight end caps 6, four inflation conduits 7 and four control valves 8; four support tubes 3 are divided into upper and lower layers and arranged in parallel (the upper support tube 3 is used as a guide rail when the solar cell substrate 1 is replaced ), each layer is provided with two support tubes 3, the two ends of each support tube 3 are closed ends, the two ends of four support tubes 3 are respectively provided with a support horizontal plate 4, and the two ends of each support tube 3 Each is connected to the support horizontal plate 4 through an end cover 6, and the four support pipes 3 are arranged ...

specific Embodiment approach 2

[0008] Specific implementation mode two: combination figure 1 Note that the supporting horizontal plate 4 of this embodiment is an aluminum alloy plate, and the length×width×thickness of the supporting horizontal plate 4=0.5m-10m×0.2m-3m×2mm-30mm. The specific size of the supporting horizontal plate can be determined according to the size, structural weight and structural function requirements of the entire sailboard. The supporting horizontal plate is the connecting part between the whole sailboard structure and the cabin structure of the space station, and has the function of supporting and fixing the whole sailboard structure. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0009] Specific implementation mode three: combination figure 1 To illustrate, the length*width*thickness of the support horizontal plate 4 of this embodiment=4.4m*0.3m*5mm-10mm. Others are the same as in the second embodiment.

Abstract

The invention discloses a double-layer frame type on-track maintainable inflation-expanding solar panel, which relates to an on-track maintainable inflation expansion solar panel, for solving the problem that it causes resource waste and threats to the life safety of astronauts that the astronauts have to walk a long distance in a spatial environment to replace an entire solar panel which is damaged or aged during on-track operation. A solar cell substrate is arranged at the position of the lower layer of a double-layer inflation-expanding frame; a first magnet exciting coil is fixedly arranged in a first mounting hole in a lower-layer supporting structural plate; an upper-layer cell plate is made of a permanent magnetic material; wires are connected with the electric heating layers of supporting pipes; a capture plate is arranged above the solar cell substrate; the capture plate is connected with a connecting rope; the connecting rope circles the two supporting pipes positioned on the upper layer in the double-layer inflation-expanding frame; the connecting rope is connected with an electrical pull rope; and a second mounting hole in the capture plate is fixedly provided with a second magnet exciting coil. The solar panel is used in manned spacecrafts such as space stations.

Description

technical field [0001] The invention relates to an inflatable deployable solar panel suitable for manned spacecraft such as a space station and capable of on-orbit maintenance, and belongs to the field of aerospace technology. Background technique [0002] Solar panels are an important part of manned spacecraft such as space stations, which convert the collected solar radiation energy into electrical energy to provide electrical support for spacecraft. The space environment is extremely complex, high vacuum, strong ultraviolet rays, atomic oxygen, "cold black" and a large number of micro meteors and space debris, which cause damage or aging of solar cells during orbital operation, which requires replacement and maintenance. The traditional method is for astronauts to replace some of the damaged or aging solar panels as a whole. In some cases, the damage is only a small part, and the overall replacement will cause a waste of resources. In addition, the size of the solar pane...
