Magnetoelectric generator and application thereof

Abstract

The invention discloses a magnetoelectric generator and application thereof. The magnetoelectric generator comprises a shell, a permanent magnet, at least two coils and at least two springs. The springs are respectively compressed and accommodated in the shell and are respectively arranged at two ends of the permanent magnet; the coils respectively sleeve the outer sides of the springs. The permanent magnet slides in the shell and cuts magnetic lines of force of the coils. The objective of the invention is to solve the problem that a magnetic recoil generator cannot realize continuous power generation in a penetration environment. Based on the law of electromagnetic induction, the impact effect on the projectile body in the target penetration process is utilized, a double-spring and double-coil structure is adopted, and the magnet can continuously move in the coil after being impacted, so that the coil can generate induced electromotive force, and continuous power supply of continuouspower generation to a fuse system is realized. The invention further provides application of the magnetoelectric generator to power supply in the target penetration process of the projectile body.

Description

technical field [0001] The invention relates to a magnetoelectric generator and its application, belonging to the field of power generating devices. Background technique [0002] The magnetic recoil generator mainly uses the recoil force of the projectile during the launch process, and through the relative linear motion of the magnetic core and the coil in the axial direction, the magnetic flux of the closed coil changes, and an induced electromotive force is generated on the coil. The magnetic recoil generator is a linear generator, which uses the recoil force to drive the magnetic core to move in a straight line. Because the recoil force driving the magnetic core movement is a pulse force, the voltage generated is a pulse voltage, which needs to be stored in a capacitor for use in the fuze circuit. It has the advantages of low temperature use, long-term storage, 100% non-destructive testing, simple structure, fast activation (about 1ms), and easy fuze sealing. The disadva...
