AI Technical Summary
Existing microsatellite release equipment has low release efficiency, making it difficult to meet the requirements for rapid and safe release of the same batch of microsatellites. Furthermore, it cannot detect the integrity of internal circuits before release, which may lead to damaged satellites and increase space debris.
A microsatellite release device was designed. It uses a rotating component to grab the satellite and perform internal circuit testing. Qualified satellites are released into a predetermined orbit, while damaged satellites are collected into a waste trough. The device utilizes components such as a drive motor, a limit slot, an elastic buckle, and a detection component to achieve efficient release and detection.
It enables efficient release and internal circuit testing of microsatellites, ensuring that qualified satellites are released as planned and damaged satellites are recovered, thus avoiding the generation of space debris and improving the efficiency and safety of the release equipment.

[0061] The basic principle of the application is:
[0062] The extraction process is:
[0063] As shown in the figure, Figure 14 As shown, the driving motor 31 drives the rotating piece 3 to rotate, the rotating piece 3 drives the micro-satellite 2 adsorbed by the suction accessory 321 to perform rotating movement, the micro-satellite 2 will move along the limiting groove one 111 and compress the elastic buckle one 114, with the movement of the micro-satellite 2, the micro-satellite 2 will compress the clamping block 432, until the micro-satellite 2 enters the inside of the release device 4, at this time, the clamping block 432 recovers under the action of the elastic rod four 433 and limits the side of the micro-satellite 2, the elastic buckle three 42 in the release device 4 limits the bottom surface of the micro-satellite 2;
[0064] As shown in the figure, Figure 15As shown, the microsatellite 2 inside the storage tank 11 will move to one side under the action of the push plate 112, waiting for the subsequent adsorption component 321 to grab it.
[0065] Testing phase:
[0066] like Figure 16 As shown, the detection element 13 drives the detection rod 131 to extend, which in turn drives the detection head 132 to move towards the release device 4 until the connector 134 is inserted into the power interface 22. The detection head 132 detects the internal circuit of the microsatellite 2 to ensure the stable operation of the microsatellite 2 and data transmission. As the detection head 132 moves, it drives the control board 142 to move to one side through the push plate 133, compressing the spring 141. The push plate 14 is restricted by the baffle 43.
[0067] Release phase:
[0068] like Figure 17 As shown, when the rotating part 3 carries the microsatellite 2 into the release device 4, the rotating part 3 will compress the pusher 152, the elastic rod 153, and the spring 151. The pusher plate 15 will be restricted by the baffle 46 and will not be able to move.
[0069] like Figure 18 As shown, when the microsatellite 2 passes the inspection, the control component 44 drives the control rod 441 to move upward, squeezing the push block 45. The telescopic tube 452 extends through the hydraulic channel 451, causing the baffle 46 to move to one side and compressing the elastic rod 462. The baffle 46 loses its restriction on the push plate 15, the spring 151 extends, and the push plate 15 moves downward, compressing the elastic buckle 42 and pushing the microsatellite 2 out of the release device 4, releasing the microsatellite 2 to the predetermined orbit.
[0070] Abandonment phase:
[0071] like Figure 19 , Figure 20 As shown, when the microsatellite 2 inside the release device 4 fails the test, the control component 44 drives the control rod 442 to extend, which in turn drives the connecting rod 434 to move downward, causing the baffle 43 and the lifting plate 431 to move downward. The push plate 14 loses the restriction of the baffle 43, and the side of the microsatellite 2 loses the restriction of the locking block 432 on the lifting plate 431. The spring 141 extends, causing the push plate 14 to move to one side, pushing the microsatellite 2 inside the release device 4 to the side. The microsatellite 2 will enter the waste tank 12 along the limiting groove 111. The elastic buckle 121 restricts the unqualified microsatellite 2 inside the waste tank 12, making it convenient to recover the waste microsatellite 2 when the launch vehicle returns.
[0072] Then the detection piece 13 drives the detection head 132 to recover, the push plate two 14 is recovered under the action of the elastic rod two 143; The control piece 44 drives the control rod two 442 to recover, drives the baffle one 43 and the lifting plate 431 to move upward; Wait for the subsequent rotating piece 3 to catch the microsatellite 2;
[0073] Repeat the above movement, that is, the extraction, detection, release and recovery of the microsatellite 2 can be completed, which meets the detection of the microsatellite 2 before launch, and can release the qualified microsatellite 2 and recover the unqualified microsatellite 2.
