Vacuum permanent magnet energy conversion system

The invention relates to a vacuum permanent magnet energy conversion system. The system comprises a walking permanent magnet block connected with a driving chain, permanent magnet blocks which performreciprocating motion, and a vacuum fixing outer frame; the walking permanent magnet block is installed on the driving chain and performs linear motion in the vacuum fixing outer frame; the reciprocating motion permanent magnet blocks are fixed side by side on two movable permanent magnet block fixing rods, so that a constant magnetic field can be formed between the two permanent magnet blocks; the linear motion walking permanent magnet block can pass a space between the two permanent magnets, so that the acting force of the constant magnetic field is changed; and the original attractive forceof the magnetic field is instantly changed to a repulsive force; the repulsive force of the magnetic field is used to push a piston rod in an air cylinder to compress air; and the attractive force ofthe magnetic field is used to drive the piston rod to return, so that the piston rod in the air cylinder retreats to be in an air intake state. According to the system, under a vacuum low-resistancecondition, the magnetic force can be converted into kinetic energy capable of working; and under the continuous action of a plurality of walking permanent magnet blocks, magnetic force energy can be applied to production and life.
