[0020] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
[0021] Such as figure 1 As shown, the bionic caudal fin underwater propeller based on hydraulic artificial muscles of the present invention includes two or more swing devices, a tail fin 1 and a hydraulic control unit (not shown in the figure), and the swing device includes a T-shaped bracket 2 and a symmetrical arrangement Two artificial muscles 3 on the T-shaped bracket 2. See figure 2 , image 3 Each artificial muscle 3 includes a telescopic component, the telescopic component has an elastic hydraulic chamber 301 that can be filled with liquid to generate one-way linear expansion, and the telescopic component is provided with a joint 302 for connecting the elastic hydraulic chamber 301 and the hydraulic control unit. During operation, the joint 302 is connected to an external hydraulic control unit, and the elastic hydraulic chamber 301 is filled...
