Description

Bird body transmitting and separating device applied to multistage electromagnetic coil Technical Field The invention belongs to the technical field of electromagnetic emission, and particularly relates to a bird body emission and separation device applied to a multistage electromagnetic coil. Background Electromagnetic emission technology has been proposed in the 19 th century at the earliest, and the development of electromagnetic emission technology is gradually paid attention to as the emission performance of chemical energy emission devices is improved to the limit. Compared with the traditional mechanical energy and chemical energy emission technology, the electromagnetic emission technology has the advantages of excellent acceleration capability, large emission quality, easy energy acquisition, good controllability and the like. During electromagnetic emission, the velocity of the projectile is affected by the atmospheric pressure. Therefore, a vacuum cabin is arranged in the electromagnetic emission process, air is pumped out, and the influence of aerodynamic resistance is eliminated. In addition, the separation of the bird body and the bullet support is also one of important links of electromagnetic emission, so that the bullet support and the bird body are prevented from being ejected simultaneously, and secondary shooting is caused on the target body. Patent CN111238296a is a mechanical shelling device of light air cannon, can satisfy the shelling demand of different bullet footpath bullets, and the bullet holds in the palm and the separation of bird body when the bullet holds in the palm with shelling section shelves ring and bump, and this separation mode belongs to physical collision type separation, and its position setting of retrieving the cabin is in shelling section shelves ring and the position between the barrel export, and in actual shell removal in-process, the bullet that separates holds in the palm has faster speed, and can be at the barrel irregular motion after receiving the impact, can not guarantee that the bullet holds in the palm directly gets into and retrieve the cabin and not influence other structures, and the bullet holds in the palm and can not be retrieved smoothly and still can the barrel produce the damage. Patent CN108362170a, patent CN111766074A, patent CN104896005A are all through the air cannon with the relevant technique and the device that the bird body held in the palm with the bullet once separate, when the bullet that loads the bird body holds in the palm reaches the exit position of launching gun barrel, through making pusher and spring assembly collide the speed reduction and then realize the separation that the bird body held in the palm with the bullet, this separation mode belongs to once only and breaks away from, can not guarantee that the bullet holds in the palm with the bird body breaks away completely, if the bullet that the bullet of launching holds in the palm along with the bird body launches, then can undoubtedly influence the transmission orbit and the precision of the bird body. Meanwhile, the residual bullet support moving irregularly can damage the gun barrel, so that the service life of the gun barrel is greatly reduced. The patent CN105823614A provides a foreign object impact experiment vacuum box sealing device under a vacuum state, and the core point of the patent is that the bird body of the emission is separated from the bullet support through physical impact, and the bullet remover is closed with the gun barrel, and the gun barrel is fixed on the base through a spring, and the opening and closing actions of the bullet remover and the gun barrel are realized through the displacement of the spring, so that the vacuum environment of the emission is realized. But when the bird body firing rate is slower, the spring compression deformation is less, and the spring compression thrust that it provided probably can not make bird body and bullet hold in the palm the separation, in addition, when bullet held in the palm for soft material, the deformation that bullet held in the palm material and the deformation that the spring took place can influence each other, can make the orbit of bird body in the barrel receive the skew, influences the pose precision that the bird body launched. Patent CN108955371B proposes an electromagnetic separation device for a bullet holder of a light air gun, which can realize stable separation between the bullet holder and a bullet by means of an electromagnetic separation system with a built-in induction element on the premise of not generating impact effect. However, one limitation of this invention is that in conducting short range firing collision experiments, the phenomenon that the sabot together with the projectile strikes the target may occur because the sabot cannot be braked or effectively retracted in real time. The invention patent of patent CN114838621A provides a multistage bullet device that takes of
