Description

Technical Field

[0001] The present invention belongs to the technical field of solar wings, and in particular relates to a flexible solar wing inflation and deployment device. Background Art

[0002] The flexible solar wing inflatable deployment device is a power supply equipment for spacecraft. It is in a folded and compressed state before entering orbit, which can not only meet the fairing envelope restrictions but also withstand the launch segment load. After entering orbit, the driving mechanism provides a pressure gas source for the extension mechanism. The extension mechanism and the tensioning mechanism drive the flexible solar wing to unfold smoothly, providing sufficient illumination area and providing the spacecraft with the energy necessary for normal operation.

[0003] The existing flexible solar array uses a composite film structure as a substrate. Unlike rigid and semi-rigid solar arrays, which require spacing between substrates in the folded state, each substrate of the flexible array is in a fitted and compacted state in the folded state. For large-area solar arrays, the folded volume can be reduced by about 1 / 10. According to different folding and unfolding methods, flexible solar arrays mainly include three forms, namely accordion unfolding, fan-shaped unfolding, and winding unfolding. The existing solar wings are large in folded volume, heavy in mass, and have poor system independence. The traditional rigid and semi-rigid solar wings have low mass-to-power and volume-to-power ratios, which cannot meet the requirements of future space missions for light mass and small storage volume of solar arrays. Summary of the invention

[0004] The technical problem solved by the present invention is to provide a flexible solar wing inflatable deployment device, which adopts an extension mode in which the flexible solar wing and the extension mechanism are synchronously deployed, thereby solving the problems of large volume and mass of the solar wing when folded and poor system independence.

[0005] The technical solution adopted by the present invention is: a flexible solar wing inflatable deployment device, including a mounting plate, an end cover, a driving mechanism, an extension mechanism and a tensioning mechanism, the tensioning mechanism including a reel, a spring, a spring fixing rod, a spring rotating member and support members at both ends, the tensioning mechanism is fixed to the top of the mounting plate by the end cover, the driving mechanism includes a gas cylinder, a gas cylinder bracket, a pipeline, a tee, an addition and discharge valve, an electric explosion valve and a pressure reducing valve, which are fixed to the upper end of the mounting plate by bolt connection, the extension mechanism includes a telescopic tube, a top connecting rod and an rubber ring, which are welded on both sides of the mounting plate, the pressure air source provided by the driving mechanism is connected to the extension mechanism through a pipeline, one end of the flexible solar wing is connected to the reel of the tensioning mechanism, and the other end is connected to the top connecting rod of the extension mechanism, so that the pressure air source is provided by the driving mechanism, the telescopic tube in the extension mechanism moves forward, the telescopic tube drives the top connecting rod to move forward, the top connecting rod drives the flexible solar wing on the reel in the tensioning mechanism to unfold, and at the same time, under the action of the tensioning force of the tensioning mechanism, the flexible solar wing is smoothly unfolded.

[0006] Preferably, when the gas cylinder in the driving mechanism is inflated, the charging and discharging valve is opened, the electric explosion valve is closed, and the external gas flows through the pipeline through the charging and discharging valve into the gas cylinder to form an inflation passage; when the gas cylinder is deflated, the electric explosion valve is opened, the charging and discharging valve is closed, and the gas flows through the electric explosion valve and the pressure reducing valve to form a deflation passage. After the gas is decompressed by the pressure reducing valve, the pressure reaches the rated pressure of the extension of the telescopic tube in the telescopic mechanism, providing a pressure gas source for the extension of the telescopic tube. When the gas cylinder is deflated, the charging and discharging valve is opened, and the remaining gas in the gas cylinder is discharged.

[0007] Preferably, the telescopic tube in the extension mechanism is a combined structure in which multiple telescopic tubes with gradually decreasing diameters are nested together, and dynamic sealing is achieved between the telescopic tubes through sealing grooves and rubber rings. Under the impact of the mechanical environment, the telescopic tubes in the telescopic mechanism will not move relative to each other due to the self-locking structure. Under the action of the pressure air source provided by the driving mechanism, the telescopic tube in the extension mechanism overcomes the pressing force of the self-locking structure to move, and the telescopic tube extends without the restriction of the self-locking structure. At the same time, the flexible solar wing unfolds during the extension of the telescopic tube of the extension mechanism. The self-locking structure is a boss and a cantilevered slot structure. When the telescopic tube is affected by the pressure air source provided by the driving mechanism, the boss of the telescopic tube will squeeze the head end of the outer telescopic tube The wedge-shaped surface of the cantilevered slot and the cantilevered slot at the head end will expand toward the inner wall of the tube when being squeezed by the boss, so that the boss of the telescopic tube can move out of the cantilevered slot of the telescopic tube outside it and release the self-locking. The telescopic tube is extended. When the telescopic tube reaches the specified position, the boss of the telescopic tube squeezes the wedge-shaped surface of the cantilevered slot at the tail end of the telescopic tube outside it. The cantilevered slot at the tail end will expand toward the inner wall of the tube under the action of squeezing, so that the boss enters the cantilevered slot. After the boss of the telescopic tube enters the cantilevered slot at the tail end of the telescopic tube outside it, the cantilevered slot contracts, so that the boss of the telescopic tube fits tightly with the cantilevered slot at the tail end of the telescopic tube outside it. The fitting position is a vertical plane and cannot move relative to each other. The boss of the telescopic tube and the cantilevered slot on its outside are self-locking.

[0008] Preferably, in the tensioning mechanism, the spring fixing rod is fixedly connected to the mounting plate, the drum is connected to the spring rotating member and the support members at both ends, one end of the spring is connected to the spring rotating member, and the other end is connected to the spring fixing rod. When the flexible solar wing is not unfolded, the drum does not rotate, and the tensioning mechanism does not generate tensioning force. When the flexible solar wing is unfolded, the drum rotates at the same time, and the rotation of the drum drives the spring rotating member to rotate, and the rotation of the spring rotating member drives one end of the spring to rotate. The other end of the spring is fixed, so that the spring generates a rotational radial force, and the radial force is transmitted to the drum through the spring rotating member, so that the drum generates a force in the opposite direction of the unfolding direction of the flexible solar wing. After unfolding, the flexible solar wing is subjected to the tensioning force of the drum in the opposite direction, so that the flexible solar wing unfolds smoothly and maintains a flat state after unfolding.

[0009] Preferably, the extension mechanism comprises n (n≥3) sections of telescopic tubes. When the first section of the telescopic tube in the extension mechanism reaches the specified position, it is self-locked with the telescopic tube outside it through a self-locking structure, ensuring that the first section of the telescopic tube will not move when it reaches the specified position. Under the action of the pressure air source provided by the driving mechanism, the second section of the telescopic tube is extended until the nth section of the telescopic tube reaches the specified position and is self-locked with the telescopic tube outside it. At this time, the flexible solar wing is fully unfolded.

[0010] The beneficial effects of the present invention are as follows: the present invention has a compact structure, a small volume, and a light weight, and increases the output power of the solar cell array technology, reduces the system weight, and reduces the storage volume. It reduces the weight of the battery circuit and reduces the demand for the bearing capacity of the extension mechanism. At the same time, it meets the development demand for the miniaturization and lightweight of the flexible solar wing deployment device.

[0011] The gas cylinder, the filling and discharging valve, the electric explosion valve and the pressure reducing valve of the driving mechanism of the present invention work together to provide a sufficient pressure source for the extension mechanism and ensure the safe and reliable operation of the driving mechanism.

[0012] The extension mechanism of the present invention adopts a self-locking structure design of a boss and a cantilevered slot, and does not move relative to each other under certain mechanical environmental impacts. When the telescopic tube is subjected to a rated pressure gas source, it overcomes the compression force of the self-locking structure to extend, and self-locks when it reaches a specified position.

[0013] The tensioning mechanism of the present invention uses the rotation of the spring to provide radial force, so that the flexible solar wing is subjected to the tensioning force during the synchronous unfolding process of the flexible solar wing and the extension mechanism, so that the flexible solar wing can be unfolded flatly and remain flat after unfolding.

[0014] The present invention provides a pressure gas source by a driving mechanism to move the telescopic tube in the extension mechanism forward, driving the flexible solar wing on the reel in the tensioning mechanism to unfold smoothly, and has the characteristics of compact structure and small occupied volume.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] The flexible solar wing of the present invention has the characteristics of small folded volume, light weight, and repeatable unfolding and folding. The mass-to-power ratio can be increased by more than 1 times compared with the traditional rigid solar array, and the folded volume can also be greatly reduced. As the flexible extension mechanism develops towards miniaturization and lightweight, the flexible solar wing will have a wider application prospect. Flexible solar wings with lighter weight and smaller storage volume have greater advantages than traditional solar arrays. Therefore, flexible solar wing inflatable deployment devices with lighter weight and smaller storage volume will gradually become a more important technical development direction in the future.

[0026] The flexible solar wing inflatable deployment device adopts an extension mode in which the flexible solar wing and the extension mechanism are deployed synchronously. The extension mechanism does not move relative to each other under the action of its self-locking structure and can withstand a certain mechanical environmental impact load. When the driving mechanism provides a pressure gas source for the extension process of the extension mechanism telescopic tube, the top connecting rod of the extension mechanism drives the flexible solar wing to unfold. During the unfolding process, the flexible solar wing is subjected to the tensioning force of the tensioning mechanism, so that it can be unfolded smoothly and remain flat after unfolding.

[0027] The basic principle is: the telescopic tube 4 in the extension mechanism does not move relative to each other under the action of the self-locking structure. When the extension mechanism is acted upon by the pressure gas source provided by the driving mechanism, the telescopic tube 4 of the extension mechanism overcomes the pressing force of the self-locking structure and moves forward. When the telescopic tube 4 in the extension mechanism reaches the specified position, the self-locking structure is used to self-lock, and the driving mechanism stops providing the pressure gas source. During the extension of the telescopic tube 4 of the extension mechanism, the flexible solar wing and the top connecting rod 5 of the extension mechanism are unfolded synchronously. During the unfolding of the flexible solar wing, the reel 17 of the tensioning mechanism 8 is driven to rotate. The rotation of the reel 17 causes the spring 19 in the tensioning mechanism 8 to generate a radial tensioning force. The radial tensioning force of the spring 19 causes the reel 17 in the tensioning mechanism 8 to generate a reverse tensioning force on the unfolding of the flexible solar wing. The flexible solar wing is unfolded flatly under the action of the tensioning force of the tensioning mechanism 8, and remains flat after unfolding.

[0028] like Figure 1 As shown, the tensioning mechanism 8 in the flexible solar wing inflatable deployment device provided in this embodiment includes a reel 17, a spring 19, a spring fixing rod 18, a spring rotating member 20 and support members 21 at both ends, the tensioning mechanism 8 is fixed to the top of the mounting plate 1 by the end cover 7, the extension mechanism includes a telescopic tube 4, a top connecting rod 5 and a rubber ring 16, which are 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 three-way valve 10, a charging and discharging valve 12, an electric explosion valve 11 and a pressure reducing valve 9, which are fixed to the upper end of the mounting plate 1 by bolts, the pressure gas source provided by the driving mechanism is connected to the extension mechanism through the pipeline 2, one end of the flexible solar wing is connected to the reel 17 of the tensioning mechanism 8, and the other end is connected to the top connecting rod 5 of the extension mechanism.

[0029] like Figure 2 As shown, the telescopic tube 4 in the extension mechanism is a combination structure in which multiple telescopic tubes with gradually decreasing diameters are nested together. In this embodiment, a nested structure of five telescopic tubes is used as an example. Dynamic sealing is achieved between the telescopic tubes 4 through sealing grooves and rubber rings 16. Under the impact of the mechanical environment, the telescopic tubes 4 in the telescopic mechanism will not move relative to each other through the self-locking structure. Under the action of the pressure gas source provided by the driving mechanism, the telescopic tube 4 overcomes the pressing force of the self-locking structure to extend.

[0030] The telescopic tube 4 and its adjacent telescopic tube 4 are self-locked through the boss 15 and the cantilevered slot 14 . Since the boss 15 is pressed by the cantilevered slot 14 , the telescopic tube 4 will not move relatively under the impact of a certain mechanical environment.

[0031] When the telescopic tube 4 is acted upon by the pressure gas source provided by the driving mechanism, the boss 15 of the telescopic tube 4 will squeeze the wedge-shaped surface of the cantilevered slot 14 at the head end of the telescopic tube 4 outside it, and the cantilevered slot 14 at the head end will expand toward the inner wall of the tube when being squeezed by the boss 15, so that the boss 15 of the telescopic tube 4 can move out of the cantilevered slot 14 of the telescopic tube 4 outside it. After the boss 15 moves out of the cantilevered slot 14, the cantilevered slot 14 shrinks and cannot act on the position limit of the telescopic tube 4 at the same time, and the telescopic tube 4 moves forward under the action of the driving mechanism. When the telescopic tube 4 reaches the specified position, the boss 15 of the telescopic tube 4 squeezes the wedge-shaped surface of the cantilevered slot 14 at the tail end of the telescopic tube 4 outside it, and the tail end cantilevered slot 14 will expand toward the inner wall of the tube under the action of squeezing, so that the boss 15 enters the cantilevered slot 14. After the boss 15 of the telescopic tube 4 enters the cantilevered slot 14 at the rear end of the telescopic tube 4 outside it, the cantilevered slot 14 shrinks, so that the boss 15 of the telescopic tube 4 and the cantilevered slot 14 at the rear end of the telescopic tube 4 outside it are tightly fitted, and the fitting position is a vertical plane, and relative movement cannot occur. The boss 15 of the telescopic tube 4 and the cantilevered slot 14 at the rear end of the telescopic tube 4 outside it are self-locking, ensuring that the moving telescopic tube 4 will not continue to move when it reaches the specified position. Among them, the head end cantilevered slot 14 refers to the cantilevered slot 14 closer to the driving mechanism side.

[0032] like Figure 1 and Figure 3 As shown, the spring fixing rod 18 in the tensioning mechanism 8 is connected and fixed to the mounting plate 1, and the two end support members 21 are sleeved on the spring fixing rod 18 and can rotate on the spring fixing rod 18. The two end support members 21 are connected to the reel 17 through the card slot and can rotate synchronously with the reel 17. The flexible solar wing is wound on the reel 17 of the tensioning mechanism 8, and the unfolding of the flexible solar wing drives the reel 17 in the tensioning mechanism 8 to rotate. The rotation of the reel 17 drives the spring rotating member 20 to rotate, and one end of the spring 19 is connected to the spring rotating member 20, and the other end is connected to the spring fixing rod 18. The rotation of the spring rotating member 20 drives one end of the spring 19 to rotate, and the spring 19 rotates at one end and is fixed at the other end, so that the spring 19 generates a radial force of rotation. The radial force of the rotation of the spring 19 is transmitted to the reel 17 through the spring rotating member 20, so that the reel 17 generates a force opposite to the unfolding direction of the flexible solar wing. After the flexible solar wing is unfolded, it is subjected to the reverse tension force of the reel 17, so that the flexible solar wing is unfolded smoothly and remains flat after unfolding.

[0033] like Figures 4 to 8 As shown, during operation, first, the gas cylinder 3 is inflated, the filling and discharging valve 12 is opened, and the gas enters the gas cylinder 3 through the filling and discharging valve 12 to realize the filling of the gas cylinder 3 with gas. After the gas cylinder 3 is completely inflated, the filling and discharging valve 12 is closed.

[0034] Then, the electric explosion valve 11 is opened through the gas release driving device in the gas cylinder 3, 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 cylinder 3 to the rated pressure required for the extension of the telescopic tube 4 in the telescopic mechanism. After being adjusted by the pressure reducing valve 9, the gas in the gas cylinder 3 passes through the tee 10 and the pipeline 2 to reach the telescopic tubes 4 on both sides of the mounting plate 1, providing power for the synchronous extension of the telescopic tubes 4 on both sides.

[0035] The first telescopic tube 4 in the telescopic mechanism overcomes the pressing force of the self-locking structure under the action of the pressure gas source of the driving mechanism and begins to extend forward. When reaching the specified position, the boss 15 of the telescopic tube 4 and the cantilevered slot 14 of the telescopic tube 4 on its outside are self-locked. Then, the second telescopic tube 4 overcomes the pressing force of the self-locking structure under the action of the pressure gas source of the driving mechanism and begins to extend forward. When reaching the specified position, the boss 15 of the telescopic tube 4 and the cantilevered slot 14 of the telescopic tube 4 on its outside are self-locked, until the nth (n=5) telescopic tube 4 is extended and self-locked.

[0036] The top connecting rod 5 drives the flexible solar wing to unfold on the reel 17 of the tensioning mechanism 8 during the extension of the first section of the telescopic tube 4. The reel 17 of the tensioning mechanism 8 applies a reverse tensioning force to the flexible solar wing to make the flexible solar wing unfold smoothly until the nth (n=5) section of the telescopic tube 4 is extended and self-locked, and the flexible solar wing is fully unfolded. After unfolding, the flexible solar wing is subjected to the reverse tensioning force of the reel 17, so that the flexible solar wing unfolds smoothly and remains flat after unfolding.

[0037] Then, the stretching mechanism finishes working, the pressure reducing valve 9 is closed, and the gas cylinder 3 stops deflation.

[0038] After the pressure reducing valve is closed, the filling and discharging valve 12 is opened to discharge the gas in the gas cylinder 3.

[0039] The above are specific embodiments of the present invention and the technical principles used. Any modifications and equivalent changes based on the technical solution of the present invention should be included in the protection scope of the present invention.
