The invention discloses a bionic underwater robot fish driving mechanism and a working method thereof. Power fin wings of the bionic underwater robot fish driving mechanism are composed of one driving fin wing and two or more driven fin wings arranged in a front and back mode. The driving fin wing is composed of a [-shaped fin frame and one or more fins vertically arranged on the [-shaped frame, each driven fin wing is composed of a [-shaped fin frame and one or more fins vertically arranged on the [-shaped frame, the two sides of the upper end of each fin are hinged to the upper frame of the corresponding fin frame through shafts, and the lower end of each fin droops behind the lower frame of the corresponding fin frame. The driving fin wing and the driven fin wings are sequentially installed on the outer side of a robot fish shell from front to back, and a parallel four-bar linkage mechanism with multiple sets connected together is formed. By means of the bionic underwater robot fish driving mechanism, it is achieved that the front and back swing of the power fin wings at different speeds and the free opening and closing of fins are completed under the premise that the turning direction of a steering engine is not changed, so that a robot fish propels forwards, and the purposes of the high moving speed, high efficiency, low noise, no grass winding and passing of narrow parts of a water channel are achieved.
