DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] When implementing: Figure 1-5 As shown, a magnetically controlled satellite unlocking and separation device comprises: a mounting frame 1, a plurality of bases 2 are arranged at the upper end of the mounting frame 1, and the plurality of bases 2 are distributed in an array along the upper end of the mounting frame 1; a separation mechanism 3, the separation mechanism 3 is arranged at the upper end of the base 2; wherein the separation mechanism 3 comprises an outer frame 31 fixedly connected to the upper end of the base 2, a positioning assembly 32 is arranged inside the outer frame 31, the surface of the positioning assembly 32 penetrates to the outside of the outer frame 31, and limited separation assemblies 33 are arranged on both sides of the outer frame 31, the limited separation assembly 33 is located inside the outer frame 31, and the upper end of the limited separation assembly 33 penetrates to the top of the outer frame 31;
[0024] like Figure 2 , Figure 3 and Figure 5As shown, the positioning assembly 32 includes a mounting platform 321 fixedly connected to the inner bottom wall of the outer frame 31 and two mounting tubes 324 fixedly connected to the side surfaces of the outer frame 31. An electromagnet 322 is embedded and installed inside the mounting platform 321. Limit clamping tubes 323 are arranged on both sides of the electromagnet 322. The limit clamping tubes 323 are slidably connected to the inner walls of the mounting tubes 324. A middle cross column 325 is fixedly connected to the inner wall of the mounting tube 324. A first spring 326 is sleeved on the surface of the middle cross column 325. The other end of the first spring 326 is fixedly connected to the inner wall of the limit clamping tube 323. The end of the limit clamping tube 323 away from the electromagnet 322 is fixedly connected to an upper limit plate 327. Two rectangular grooves are provided at the upper end of the upper limit plate 327. The device controls the electromagnet 322 so that the electromagnet 322 generates magnetic force when it is powered on, thereby generating magnetic attraction on the end of the limit clamping tube 323, so that the limit clamping tube 323 is firmly adsorbed on the end surface of the electromagnet 322. When the electromagnet 322 is no longer powered on, the magnetic attraction effect on the limit clamping tube 323 is released. At this time, the limit clamping tube 323 moves toward the direction of the middle cross column 325 under the action of the first spring 326. At this time, when the limit clamping tube 323 moves, the upper limit plate 327 is driven to move with it.
[0025] like Figure 1 , Figure 2 and Figure 4 As shown, the limiting separation component 33 includes an outer tube 331 fixedly connected to the inner bottom wall of the outer frame 31, the inner wall of the outer tube 331 is slidably connected with a separation tube 332, the upper end of the separation tube 332 passes through the top of the outer frame 31, the surface of the separation tube 332 is fixedly connected with a first clamping block 333, the first clamping block 333 is slidably connected to the inner wall of the outer frame 31, the interior of the outer tube 331 is provided with a middle sliding rod 334 fixedly connected to the inner bottom wall of the outer frame 31, the surface of the middle sliding rod 334 is sleeved with a second spring 335, the second spring 335 is fixedly connected to the lower end of the separation tube 332, a sliding groove 336 is opened on one side of the outer tube 331, and a second clamping block 337 is fixedly connected to one side of the separation tube 332, and the second clamping block 337 passes through the sliding groove 336. When the limit clamp tube 323 remains adsorbed, the position of the separation tube 332 is limited by the limit clamp tube 323 and the cooperation with the second clamp block 337, and the upper limit plate 327 synchronously limits the first clamp block 333, thereby achieving a double limit effect. When the limit clamp tube 323 moves, the limit clamp tube 323 releases the restriction on the second clamp block 337, and the upper limit plate 327 also releases the restriction on the first clamp block 333, thereby allowing the separation tube 332 to be separated.
[0026] When the utility model is in use, the device controls the electromagnet 322. The electromagnet 322 generates magnetic force when it is energized, thereby generating magnetic attraction on the end of the limit clamping tube 323. The limit clamping tube 323 is firmly adsorbed on the end surface of the electromagnet 322. When the limit clamping tube 323 remains adsorbed, the position of the separation tube 332 is limited under the action of the limit clamping tube 323 and the cooperation of the second clamping block 337. At the same time, the upper limit plate 327 synchronously limits the first clamping block 333. When the electromagnet 322 is no longer energized, the magnetic attraction effect on the limit clamping tube 323 is released. At this time, the limit clamping tube 323 moves toward the direction of the middle cross column 325 under the action of the first spring 326. At this time, when the limit clamping tube 323 moves, the upper limit plate 327 is driven to move with it. At this time, the limit clamping tube 323 releases the restriction on the second clamping block 337, and the upper limit plate 327 also releases the restriction on the first clamping block 333, thereby separating the separation tube 332.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
