Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of phased array antennas, and in particular relates to a high-rigidity compression and release device suitable for phased array antennas. Background Art
[0002] The SAR antenna is usually stowed in a π-type or an encircling stowage mode. The π-type is that the body-mounted subarray is directly fixed to the +Z (ground-facing) panel of the satellite, and the two deployed subarrays are stowed on the ±X side panels of the middle subarray. In the orbital state, the two deployed subarrays are deployed around the sides of the middle subarray in sequence. The encircling stowage mode is that the middle subarray is directly fixed to the +Z (ground-facing) panel of the satellite, and the two deployed subarrays are stowed above the middle subarray in an encircling manner. In the orbital state, the outer subarray is deployed first, and the inner subarray continues to deploy after the outer subarray is fully deployed. The three subarray antennas eventually form a coplanar surface.
[0003] The SAR antenna accounts for approximately 20% to 40% of the satellite's mass. As the most important component on a satellite, the SAR's compression and release mechanism plays a crucial role during launch. The compression and release mechanism provides sufficient compression and fixation for the antenna subarray during launch, resisting external loads from all directions and ensuring the safety of the SAR antenna during launch.
[0004] SAR antenna subarrays typically use four clamping locations, each of which can be simplified to a single clamping point. Dynamic analysis is used to appropriately adjust the spacing between these four clamping points to ensure high clamping stiffness when the antenna is stowed. When the SAR antenna subarray is long, even with four clamping points optimally located through dynamic analysis, this may not be sufficient to maintain high clamping stiffness when the antenna is stowed. This requires increasing the number of clamping points, but this increases manufacturing costs and power supply complexity. Summary of the Invention

A shear-resistant cone sleeve is provided at one end of the clamping frame 13. The support seat 11 is fixedly connected to the body-mounted sub-array 5 through the right-angle mounting surface 113, and a body-mounted sub-array 5 insulation pad 15 is provided between the support seat 11 and the body-mounted sub-array 5. In this embodiment, as Figure 3 and Figure 4 As shown, the distance between the two pressing frames 13 can be adjusted by changing the mounting interface of the upper mounting surface 112 , and the thermal insulation pad 15 of the support base 11 and the body-mounted sub-array 5 play a role in thermal insulation protection.
[0044] In a preferred embodiment of the present invention, the sub-board connection support frame assembly 2 includes two lower clamping columns 21, a lower support frame 22 and two inner expansion plate clamping nuts 23, one end of the lower clamping column 21 is provided with an internal thread, and the other end of the lower clamping column 21 is provided with a shear cone sleeve, one end of the inner expansion plate clamping nut 23 is provided with an external thread, and the other end of the inner expansion plate clamping nut 23 is provided with a shear cone sleeve, the two lower clamping columns 21 are respectively located on both sides of the bottom of the lower support frame 22, and the two inner The expansion plate pressing nuts 23 are respectively located on both sides of the top of the lower support frame 22, and the lower clamping column 21 and the inner expansion plate pressing nut 23 are respectively inserted into the reserved holes of the lower support frame 22, and the two are connected by threads inside the lower support frame 22, and the lower clamping column 21 and the inner expansion plate pressing nut 23 are fastened to the lower support frame 22; the sub-board connection support frame assembly 2 also includes two upper clamping columns 24, an upper support frame 26 and two outer expansion plate pressing nuts 27, one end of the upper clamping column 24 is provided with an internal thread, and The other end of the upper clamping column 24 is provided with a shear cone sleeve, the two upper clamping columns 24 are respectively located on both sides of the bottom of the upper support frame 26, and the two outward expansion plate pressure nuts 27 are respectively located on both sides of the top of the upper support frame 26. One end of the outward expansion plate pressure nut 27 is provided with an external thread, and the upper clamping column 24 and the outward expansion plate pressure nut 27 are respectively inserted into the reserved holes of the upper support frame 26, and the two are connected by threads inside the upper support frame 26. The upper clamping column 24 and the outward expansion plate pressure nut 27 are fastened to The upper support frame 26; the sub-board connection support frame assembly 2 also includes two sub-board thermal insulation pads 25, one of which is located between the upper support frame 26 and the outward expansion sub-array 7, and the other sub-board thermal insulation pad 25 is located between the lower support frame 22 and the outward expansion sub-array 7; the upper clamping column 24 is connected to the inner expansion plate pressure nut 23 below it through a shear cone sleeve, and the lower clamping column 21 is connected to the clamping frame 13 below it through a shear cone sleeve; the contact surface of the shear cone sleeve is sprayed with a tungsten carbide high friction coating. In this embodiment, if Figure 5 and Figure 6 As shown, the lower clamping column 21, the upper clamping column 24 and one end of the inner expansion plate pressure nut 23 are provided with concave and convex shear-resistant cone sleeves to form adjacent fitting surfaces. The load in the normal direction of the contact surface can be borne along the axis of the two. The tangential friction force generated by the positive pressure on the contact surface is used to resist the tangential force of the contact surface. A tungsten carbide high-friction coating is sprayed on the adjacent fitting surfaces to increase the shear resistance. At the same time, a shear-resistant cone sleeve with a gap is introduced as the second line of defense against shear. Even if lateral displacement occurs due to insufficient friction, the displacement will be limited to a certain range to avoid damage to other components such as hinges. The sub-board thermal insulation pad 25 plays the role of thermal insulation protection.
[0045] In a preferred embodiment of the present invention, the clamping assembly 3 includes a clamping rod 31, a clamping plate 32, an adjusting ball pad 33, a separation spring 34, a spring sleeve 35, a locking nut 36 and a capture cap 37. The two ends of the clamping rod 31 are respectively provided with external threads. The clamping rod 31 passes through the clamping plate 32, the adjusting ball pad 33, the separation spring 34 and the spring sleeve 35. A spherical groove is provided in the middle of the clamping rod 31, and the spherical groove is used to place the adjusting ball pad 33. The top of the adjusting ball pad 33 is connected to the bottom of the separation spring 34, and the top of the separation spring 34 is connected to the spring sleeve 35 boss. The base of the spring sleeve 35 is provided with a plurality of screw threads. The body is penetrated by the separation spring 34, the top of the spring sleeve 35 is connected to the locking nut 36, the locking nut 36 is threadedly sleeved on one end of the clamping rod 31, and the capture cap 37 is installed on the outside of the spherical groove of the clamping plate 32. The base of the capture cap 37 is an inverted cylindrical cover, and the top of the cylindrical cover of the capture cap 37 is located directly above the locking nut 36. The clamping rod 31 passes through the sub-plate connected to the support frame assembly 2, and the clamping rod 31 is bolted to the memory alloy expander 14 of the base assembly 1; the sub-plate connected to the support frame assembly 2 is bolted to the expansion plate pressure nut 27 and the clamping plate 32 of the clamping assembly 3 above it. In this embodiment, as Figure 7 and Figure 8As shown, in the clamping state, the external thread at the lower part of the clamping rod 31 cooperates with the slotted bolt inside the memory alloy expander 14, the external thread at the upper part of the clamping rod 31 cooperates with the locking nut 36, and the adjusting ball pad 33 cooperates with the spherical groove feature reserved inside the clamping plate 32 to play a role of fine-tuning. The separation spring 34 is located between the adjusting ball pad 33 and the spring sleeve 35, which can provide the upward separation elastic force of the spring sleeve 35. The distance from the locking nut 36 to the contact surface of the adjusting ball pad 33 and the clamping plate 32 is large, and there is a spring in the middle. The sleeve 35, when the clamping rod 31 and the memory alloy expander 14 are tightened, a large restoring torque will be generated on the adjustment ball pad 33 to ensure that the clamping rod 31 can be perpendicular to the expanded sub-array. The capture cap 37 can limit the pop-up distance of the clamping rod 31, and the clamping rod 31 is pushed against the upper part of the capture cap 37 by the separation spring 34. If it is not limited, the clamping rod 31 will be quickly popped out by the separation spring 34 until the lower end of the clamping rod 31 contacts the clamping plate 32, and then it will quickly rebound due to inertia. The whole movement process is The risk of scratching the surrounding structure is that according to the thickness of the different expanded sub-arrays that need to be compressed, the pop-up distance of the clamping rod 31 can be controlled by adjusting the height of the capture cap 37 to ensure that it can be popped out and deployed smoothly. The pre-tightening force of the clamping rod 31 is used to bear the load in the normal direction of the installation surface. The external load perpendicular to the direction of the clamping rod 31 is mainly resisted by the tangential friction force generated by the positive pressure applied by the clamping rod 31 on the support between each plate. The memory alloy expander 14 is used for compression and release. Its core expander assembly consists of 363 parts: a memory alloy metal tube (unlocking column), a slotted bolt, and a locking nut. The slotted bolt passes through the metal tube to compress the plate to be separated, and is finally screwed into the locking nut 36, and a certain pre-tightening torque is applied to press the entire plate to be separated onto the support structure. This is a compressed state. When release is required, the memory alloy metal tube power supply cable is energized, and the memory alloy tube inside it is heated and stretched, pressing the slotted bolt until the slotted bolt breaks from its weak point (notch), thereby realizing the release and separation of the separation plate.
[0046] Example 1:
[0047] like Figure 9 As shown, when clamping, the connection and cooperation between the clamping rod 31, the memory alloy expander 14 and the locking nut 36 provide an overall downward pre-tightening force, and the pre-tightening force is transmitted to the clamping plate 32 through the spring sleeve 35 and the adjusting ball pad 33, and further through the external expansion plate clamping nut 27 in contact with both sides of the clamping plate 32, the clamping column screwed to the external expansion plate clamping nut 27, the internal expansion plate clamping nut 23 in contact with the clamping column, the clamping column screwed to the internal expansion plate clamping nut 23, the clamping frame 13 in contact with the clamping column, and the support seat 11 screwed to the clamping frame 13, the force is finally transmitted to the star platform 4, thereby improving the overall clamping stiffness.
[0048] like Figure 10 and Figure 11 As shown, when released, the first step is to energize the power supply cable of the memory alloy expander 14, and the memory alloy tube inside it is heated and elongated, pressing the slotted bolt until the slotted bolt breaks from its weak point (notch). At this time, the clamping rod 31, under the elastic force of the upper separation spring 34, carries the upper spring sleeve 35, the locking nut 36 and the broken end of the slotted bolt at the lower part and pops up together. At this time, the clamping rod 31 no longer provides the overall preload force, and further the inner expansion sub-array 6 and the outer expansion sub-array 7, under the action of the root torsion spring, carry the sub-plate connection support frame assembly 2 installed thereon and separate from the adjacent fitting surface, thereby realizing the release and expansion of the inner expansion sub-array 6 and the outer expansion sub-array 7.
[0049] The advantages and beneficial effects of the present invention are as follows:
[0050] (1) The single-point clamping force provided by the slotted bolt in the memory alloy expander is divided into two clamping points with a certain distance, so that each clamping release device can provide a pair of clamping forces.
[0051] (2) Adjust the relative position of the clamping and releasing device, change the structure of the clamping and releasing device, and adjust the spacing between the internal pairs of clamping points to provide a higher clamping stiffness while keeping the number of clamping and releasing devices unchanged (such as using 4), thereby being applicable to a wider range of antenna lengths.
[0052] (3) On the basis of increasing the clamping points and improving the clamping stiffness, the manufacturing cost and power supply complexity are not increased.
[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
