In order to improve stability and reliability of the flexible solar cell panel, it is preferable that the movable bracket 2 in the present embodiment includes a first long rod 21, a second long rod 22, a sliding pin 23, and a rotating pin 24, wherein the first long rod 21 is rotatably connected to the connection base plate 1 through the rotating pin 24, and a moving end of the second long rod 22 is slidably connected to the slide rail through the sliding pin 23. The first tightening rope 31 on the driving device 3 and the second tightening rope 43 on the tightening release assembly 4 are simultaneously connected with the sliding pin 23 in a tightening way, so that when the star system sends out an unfolding electric signal, the second tightening rope 43 breaks, the sliding pin 23 can move on the sliding rail, and the second long rod 22 is driven to move around the connecting bottom plate 1, so that the movable bracket 2 is unfolded.
Preferably, a plurality of support rods 25 are provided between the first and second long rods 21 and 22, thereby facilitating the improvement of stability and reliability of the first and second long rods 21 and 22. Meanwhile, the supporting rod 25 can also play a role in connection, that is, when the sliding pin 23 drives the second long rod 22 to rotate, the second long rod 22 can drive the first long rod 21 to rotate around the rotating pin 24 through the supporting rod 25, at the moment, the movable support 2 is gradually unfolded, so that the flexible solar cell on the movable support 2 can be unfolded to absorb light energy to generate electricity, and further energy supply of satellites can be met.
More preferably, in this embodiment, the supporting rod 25 is connected to the first long rod 21 and the second long rod 22 through deep groove ball bearings (not shown), and of course, the operator may also set other connection modes that are convenient for the expansion and the folding of the movable support 2, which will not be described in detail here. The movable support 2 is made of carbon fiber materials with high rigidity and light weight, and the distance between the first long rod 21 and the second long rod 22 is sequentially reduced along with the increase of the distance from the connecting bottom plate 1, so that the bearing capacity of the movable support 2 can be further improved, the stability of the flexible solar cell arranged on the movable support 2 is further improved, and meanwhile, the movable support 2 is lighter. It is worth noting that, along the direction of keeping away from the connection bottom plate 1, the thickness of movable support 2 reduces gradually, so that not only can the consumptive material of movable support 2 be saved, but also the stability and the reliability of movable support 2 atress can be improved simultaneously, and the life of movable support 2 is prolonged.
The working process of the solar wing deployment device in this embodiment is as follows:
(1) When the satellite is in orbit, the sun span opening device is usually in a folded state, the first tensioning rope 31 and the second tensioning rope 43 are simultaneously tied on the sliding pin 23, at this time, the second tensioning rope 43 is wound on the second fixed column 42, and an operator can insert a wrench into the first rotating shaft 33 and screw the wrench, so that the elastic piece 32 in the driving device 3 obtains enough pretightening force, and further the smooth unfolding of the following movable bracket 2 is facilitated.
(2) When the satellite runs in orbit, the solar span opening device is usually in an unfolding state, so that the flexible solar cell on the movable bracket 2 can absorb light energy to perform photoelectric conversion so as to meet the energy supply of the satellite.
When the solar wing unfolding device needs to be unfolded, the satellite service system in the satellite can electrify the wire burning resistor 411 in the wire burning mechanism 41, so that the wire burning resistor 411 can generate a large amount of heat in a very short time, the second tensioning rope 43 is blown out (the first tensioning rope 31 is still tied on the sliding pin 23), the elastic piece 32 in the driving device 3 loses pretightening force, the elastic piece 32 needs to be restored, at the moment, the elastic piece 32 can drive the second rotating shaft 34 to rotate in a clockwise direction, the second rotating shaft 34 drives the third rotating shaft 35 to rotate, the third rotating shaft 35 drives the wire wheel 36 to rotate in a clockwise direction, the third rotating shaft 35 can retract into the driving device 3 under the clamping cooperation of the clamping piece 3621 and the clamping part 351, and the first tensioning rope 31 can drive the sliding pin 23 on the movable bracket 2 to move in a direction close to the driving device 3, and when the sliding pin 23 moves to the end of the sliding rail close to the driving device 3, the movable bracket 2 is completely unfolded. When the sliding pin 23 slides to the end termination position of the sliding rail close to the driving device 3, the elastic piece 32 still maintains a certain pretightening force to maintain the unfolding state of the solar span opening device, so that the flexible solar cell of the solar span opening device can absorb light energy, and the light energy is converted into electric energy to meet the energy requirement during normal operation of the satellite.
