Intelligent cleaning robotic fish with deepwater net cage

The utility model discloses a deepwater net cage intelligent cleaning robotic fish, and relates to the field of underwater robots. Comprising a robotic fish which is provided with an inner cavity and an outer cavity; the centrifugal pump is fixedly connected with the robotic fish; a water inlet of the centrifugal pump is communicated with the outside of a robotic fish cavity; the water spraying disc is arranged below the robotic fish and is communicated with a water outlet of the centrifugal pump through a rotary sealing shaft which is fixedly connected with the water spraying disc; the cavitation nozzle is used for cleaning the deepwater net cage, is fixedly connected with the water spraying disc and is communicated with the water spraying disc; by remotely controlling the robotic fish, the robotic fish is adsorbed on the surface of the deepwater net cage for cleaning by using the water spraying disc and the cavitation nozzle arranged on the robotic fish, so that the remote cleaning of the deepwater net cage
