Power device and swimming pool cleaning robot

Abstract

A power device is provided, which includes a driving motor connected to a main control module. Front and rear ends of the driving motor are provided with synchronous rotating main driving shafts. The main driving shafts indirectly drive driven shafts, a clutch device is provided between the main driving shafts and the driven shafts and drives the driven shafts and the main driving shafts to rotate according to a rotation direction of the main driving shafts. Rotating propellers for pushing water are provided on the driven shafts. Compared with existing technology, the power device has main driving shafts extending from two ends of the driving motor. The forward and reverse rotation of the driving motor respectively drives the corresponding rotating propellers on the driven shafts to rotate, discharge water flow, generate reverse thrust, and achieve forward and backward movement. The structure is simple and reduces volume.
