The invention discloses a variable-structure self-powered marine riser vortex-induced vibration suppression bionic robot which comprises a flow dividing tip, an upper fixing ring, a lower fixing ring, a rear cavity and two spoilers. The shunting tip and the rear chamber are oppositely mounted on the upper fixing ring and the lower fixing ring; the upper end and the lower end of the rear cavity are each provided with an annular extending part, and spoiler plate clamping grooves are formed in the annular extending parts. The front ends of the two spoilers are installed in the spoiler clamping groove in a V-shaped sliding mode, and vortex starting plates are arranged at the front ends of the spoilers. A crawling device is arranged in the shunting tip and is used for enabling the whole robot to do up-and-down or rotary motion; universal wheels and a floating and sinking device are arranged in the rear cavity, and the floating and sinking device is used for driving the whole robot to float and sink up and down; and an ocean current sensor and a pressure sensor are arranged on the shunting tip. Compared with a fixed passive vibration suppression scheme, the method has the advantages of being flexible, efficient, convenient to maintain and good in expansibility.
