The protection buffering device comprises an elevator shaft, a lift car and two protection buffering devices, in the up-down moving process of the elevator, a wheel disc can be driven by a roller to rotate forwards or backwards, so that a rotor of a micro generator is driven to rotate forwards or backwards, and the micro generator generates forward current and reverse current; meanwhile, the elevator can generate the phenomena of overweight and weightlessness, so that an arc sliding column slides up and down in an arc sliding groove, the orientation of the first electromagnet is changed, and the first electromagnet obliquely faces a first permanent magnet; when the elevator falls to the bottom, the magnetic field of the first electromagnet is increased, the first electromagnet and the first permanent magnet repel each other, the descending speed of the car is delayed, and when the elevator rushes to the top, the current direction of the micro generator is changed through contact of the contact switch and the contact block and a commutator, so that the magnetic pole of the first electromagnet is changed again and is the same as that of the first permanent magnet; therefore, the ascending speed of the lift car is slowed down, and the protection and buffering effects are achieved.
本发明公开一种用于电梯的防护缓冲装置,包括电梯井、轿厢和两个防护缓冲装置,在电梯上下移动的过程中,滚轮会带动轮盘正/反转,从而带动微型发电机的转子正转和反转,使得微型发电机产生正向电流和反向电流,也使得第一电磁铁改变磁极,同时电梯会产生超重和失重的现象,使得圆弧滑柱在圆弧滑槽内部上下滑动,改变第一电磁铁朝向,并斜对第一永磁铁;电梯坠底时,第一电磁铁磁场增大,且与第一永磁铁的相互排斥,延缓轿厢下降的速度,电梯冲顶时,通过接触开关和接触块的接触以及换向器,改变微型发电机电流方向,使得第一电磁铁的磁极再次改变,且与第一永磁铁的磁极相同,从而延缓轿厢上升的速度,起到防护缓冲的效果。
