Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The flexible solar wing has the characteristics of small furled volume, light weight, capability of being repeatedly unfolded and folded and the like, the mass specific power can be improved by more than 1 time compared with that of a traditional rigid solar cell array, and the furled volume can be greatly reduced. With the development of miniaturization and light weight of the flexible stretching mechanism, the flexible solar wing has wider application prospect. The flexible solar wing with lighter weight and smaller storage volume has greater advantages than the traditional solar cell array, so the flexible solar wing inflation and unfolding device with lighter weight and smaller storage volume gradually becomes a more important technical development direction in the future.
The flexible solar wing inflatable unfolding device adopts an extending mode that the flexible solar wing and the stretching mechanism are unfolded synchronously, the stretching mechanism does not move relatively under the action of the self-locking structure of the stretching mechanism, and a certain mechanical environment impact load can be borne. When the driving mechanism provides a pressure air source for the extension process of the extension pipe of the extension mechanism, the connecting rod at the top end of the extension mechanism drives the flexible solar wing to extend, the flexible solar wing is tensioned by the tensioning mechanism in the extension process, the flexible solar wing is flatly extended, and the flexible solar wing is kept in a flat state after being extended.
The basic principle is as follows: the extension tube 4 in the extension mechanism does not move relatively under the action of the self-locking structure, when the extension mechanism is under the action of a pressure air source provided by the driving mechanism, the extension tube 4 of the extension mechanism overcomes the pressing force of the self-locking structure to move forwards, when the extension tube 4 in the extension mechanism reaches a specified position, the self-locking structure performs self-locking, and the driving mechanism stops providing the pressure air source. In the process that the extension mechanism extension tube 4 extends, the flexible solar wing and the extension mechanism top end connecting rod 5 are synchronously unfolded, the flexible solar wing drives the winding drum 17 of the tensioning mechanism 8 to rotate in the process of unfolding, the winding drum 17 rotates to enable the spring 19 in the tensioning mechanism 8 to generate radial tensioning force, the radial tensioning force of the spring 19 enables the winding drum 17 in the tensioning mechanism 8 to generate reverse tensioning force for unfolding of the flexible solar wing, the flexible solar wing is unfolded flatly under the tensioning force of the tensioning mechanism 8, and the flexible solar wing keeps a flat state after being unfolded.
As shown in fig. 1, the tensioning mechanism 8 in the flexible solar wing inflation and deployment device provided in this embodiment includes a winding drum 17, a spring 19, a spring fixing rod 18, a spring rotating member 20, and two end supporting members 21, the tensioning mechanism 8 is fixed on the top end of the mounting plate 1 by an end cover 7, the deployment mechanism includes an extension tube 4, a top end connecting rod 5, and a rubber ring 16, and is installed on both sides of the mounting plate 1, the driving mechanism includes a gas cylinder 3, a gas cylinder bracket 13, a pipeline 2, a tee joint 10, an exhaust adding valve 12, an electro-explosive valve 11, and a pressure reducing valve 9, and is fixed on the upper end of the mounting plate 1 by a bolt connection, a pressure gas source provided by the driving mechanism is connected to the deployment mechanism through the pipeline 2, one end of the flexible solar wing is connected to the winding drum 17 of the tensioning mechanism 8, and the other end is connected to the top end connecting rod 5 of the deployment mechanism.
As shown in fig. 2, the telescopic tube 4 in the extension mechanism is a combined structure in which a plurality of telescopic tubes with gradually decreasing diameters are nested together, and this embodiment takes a nested structure of 5 telescopic tubes as an example. The telescopic pipes 4 are dynamically sealed through the sealing grooves and the rubber rings 16, the telescopic pipes 4 in the telescopic mechanism cannot move relatively through the self-locking structures under the impact of a mechanical environment, and the telescopic pipes 4 overcome the pressing force of the self-locking structures to extend under the action of a pressure air source provided by the driving mechanism.
The extension tube 4 and the adjacent extension tube 4 are self-locked through the boss 15 and the cantilever type clamping groove 14, and the extension tube 4 cannot move relatively under the impact of a certain mechanical environment because the boss 15 is pressed by the cantilever type clamping groove 14.
When the telescopic pipe 4 is under the action of a pressure air source provided by the driving mechanism, the boss 15 of the telescopic pipe 4 can extrude the wedge-shaped surface of the cantilever type clamping groove 14 at the head end of the telescopic pipe 4 outside the telescopic pipe, and the cantilever type clamping groove 14 at the head end can expand towards the inner wall of the telescopic pipe when being extruded by the boss 15, so that the boss 15 of the telescopic pipe 4 can move out of the cantilever type clamping groove 14 of the telescopic pipe 4 outside the telescopic pipe. After the boss 15 moves out of the cantilever type clamping groove 14, the cantilever type clamping groove 14 contracts, meanwhile, the limiting effect on the telescopic pipe 4 cannot be achieved, and the telescopic pipe 4 moves forwards under the effect of the driving mechanism. When the extension tube 4 reaches a designated position, the boss 15 of the extension tube 4 extrudes the wedge-shaped surface of the cantilever clamping groove 14 at the tail end of the extension tube 4 outside the extension tube, and the cantilever clamping groove 14 at the tail end expands towards the inner wall of the tube under the extrusion action, so that the boss 15 enters the cantilever clamping groove 14. After the boss 15 of the extension tube 4 enters the cantilever type clamping groove 14 at the tail end of the extension tube 4 outside the extension tube, the cantilever type clamping groove 14 contracts, so that the boss 15 of the extension tube 4 is tightly attached to the cantilever type clamping groove 14 at the tail end of the extension tube 4 outside the extension tube, the attachment position is a vertical plane, relative movement cannot occur, self-locking is realized between the boss 15 of the extension tube 4 and the cantilever type clamping groove 14 at the tail end of the extension tube 4 outside the extension tube, and the extension tube 4 which moves cannot move continuously when reaching a specified position. The first-end cantilever clamping groove 14 refers to the cantilever clamping groove 14 closer to the driving mechanism.
As shown in fig. 1 and 3, the spring fixing rod 18 of the tensioning mechanism 8 is fixedly connected with the mounting plate 1, and the two end supporting pieces 21 are sleeved on the spring fixing rod 18 and can rotate on the spring fixing rod 18. The supporting pieces 21 at the two ends are connected with the winding drum 17 through clamping grooves and can synchronously rotate along with the winding drum 17. The flexible solar wing is wound on the winding drum 17 of the tensioning mechanism 8, and the winding drum 17 in the tensioning mechanism 8 is driven to rotate by the unwinding of the flexible solar wing. The reel 17 rotates to drive the spring rotating part 20 to rotate, and one end of the spring 19 is connected with the spring rotating part 20 and the other end is connected with the spring fixing rod 18. The spring rotating part 20 rotates to drive one end of the spring 19 to rotate, and the rotating end of one end of the spring 19 is fixed, so that the spring 19 generates a rotating radial force. The radial force of the spring 19 rotation is transmitted to the spool 17 through the spring rotor 20, causing the spool 17 to generate a force in the opposite direction to the flexible sun wing opening direction. After being unfolded, the flexible solar wing is subjected to the reverse tensioning force of the winding drum 17, so that the flexible solar wing is unfolded flatly and keeps a flat state after being unfolded.
As shown in fig. 4 to 8, during operation, firstly, the gas cylinder 3 is charged, the charging and discharging valve 12 is opened, gas enters the gas cylinder 3 through the charging and discharging valve 12, so that the gas cylinder 3 is charged, and after the gas cylinder 3 is charged, the charging and discharging valve 12 is closed.
Then, by the gas discharge driving means in the gas cylinder 3, the electric explosion valve 11 is opened, and the gas in the gas cylinder 3 flows into the pressure reducing valve 9. The pressure reducing valve 9 is opened to adjust the gas pressure output by the gas bottle 3 to the rated pressure required by the extension of the extension tube 4 in the extension mechanism. After being regulated by a pressure reducing valve 9, the gas in the gas bottle 3 reaches the telescopic pipes 4 on the two sides of the mounting plate 1 through a tee joint 10 and a pipeline 2, and provides power for the synchronous extension of the telescopic pipes 4 on the two sides.
Under the action of a driving mechanism pressure air source, a 1 st extension tube 4 in the extension mechanism overcomes the pressing force of a self-locking structure and begins to extend forwards, when the extension tube reaches a specified position, a boss 15 of the extension tube 4 and a cantilever type clamping groove 14 of the extension tube 4 outside the extension tube realize self-locking, then a 2 nd extension tube 4 overcomes the pressing force of the self-locking structure and begins to extend forwards under the action of the driving mechanism pressure air source, when the extension tube reaches the specified position, the boss 15 of the extension tube 4 and the cantilever type clamping groove 14 of the extension tube 4 outside the extension tube realize self-locking, and till the nth (n is 5) extension tube 4 finishes extending and self-locking.
The top end connecting rod 5 drives the flexible solar wing to be unfolded on a winding drum 17 of the tensioning mechanism 8 in the extending process of the 1 st section of the extension tube 4, the winding drum 17 of the tensioning mechanism 8 provides reverse tensioning force for the flexible solar wing to enable the flexible solar wing to be unfolded flatly until the extension and self-locking of the nth section of the extension tube 4 are completed, and the flexible solar wing is unfolded completely. After being unfolded, the flexible solar wing is tensioned reversely by the winding drum 17, so that the flexible solar wing is unfolded flatly and keeps a flat state after being unfolded.
The operation of the extension mechanism is then ended, the pressure relief valve 9 is closed and the deflation of the gas cylinder 3 is stopped.
After the pressure reducing valve is closed, the charging and discharging valve 12 is opened to discharge the gas in the gas cylinder 3.
The above description is the specific embodiment of the present invention and the technical principle applied, and any modification and equivalent transformation based on the technical solution of the present invention should be included in the protection scope of the present invention.
