The invention relates to a device for reducing submarine propeller noise, submarine hydrodynamic wake flow and submarine thermal wake flow, which consists of a submarine fairing, a support steel beam, an electric control cabinet, a cable connected with a submarine control center, a hydraulic station, a hydraulic pipeline and signal line, a support beam anechoic tile, a connector anechoic tile, a connector bolt and a submarine center control platform. The flow guide cover has the functions of turning upwards, downwards, leftwards and rightwards and has the condition for solving the problem, the flow guide cover is functionally used for breaking cavitation bubbles through the bubble breaking ring body, the cavitation bubbles are broken in the flow guide cover, noise is solved by the sound absorption device and the structure of the flow guide cover when the noise is transmitted outwards in the flow guide cover, and the problem of noise from low frequency to high frequency is reduced; the length of the flow guide cover and a plating layer for absorbing heat of water molecules solve the problem of cooling by heat of hot water molecules, the length of the flow guide cover covers the propeller, a horn mouth structure is arranged at a tail outlet, the problem of hydrodynamic wake flow traces is solved, and torpedo attacks guided by sonar and wake flow are prevented.
