The invention belongs to the technical field of ocean robots, and particularly relates to a lift type high speed ocean robot. The lift type high speed ocean robot comprises a main body, a foldable front wing, a foldable rear wing, appendages, a main propulsion device and side propulsion devices, wherein the two appendages are symmetrically arranged on two sides of the main body, the appendages on the two sides of the main body are connected with the main body through the foldable front wing and the foldable rear wing, the main propulsion device is arranged on a stern of the main body, the side propulsion devices are arranged on sterns of the appendages on the two sides of the main body, and switching of water surface navigation and underwater navigation states of the lift type high speed ocean robot can be achieved through synchronous folding and unfolding of the foldable front wing and the foldable rear wing is achieved. The lift type high speed ocean robot has the advantages of requiring low for the own balance weight, being capable of storing large buoyancy force, high in rising or diving speed, and good in maneuvering characteristic and the like, has excellent adaptive capacity to environment and excellent load carrying ability, and can execute tasks of load transportation or delivery, deep sea scientific investigation and the like.
