The invention discloses a rotation current collector. The current collector comprises an annular wiring board which is fixedly installed on an overturn rotating shaft of an upender and is synchronously rotated with the overturn rotating shaft. The wiring board is provided with a wiring component. An inner side of the wiring board is provided with a brush component which is contacted with a conductive board on a corresponding side of the wiring board in a slide mode. The brush component is fixedly arranged on a vehicle frame of the upender. In the invention, a lead which is connected to a vehicle body and the brush component which is connected to a power supply terminal realize rotation and slide connection and positive and negative rotation can be achieved, and conduction is not influenced.
