The utility model belongs to the technical field of ocean buoy equipment, and discloses an intelligent air interchanger for a buoy. The device comprises a shaft; a hatch cover isolated from the outside is sealed at the top of the shaft; the shaft is fixed on the shaft shell; the shaft shell is fixedly connected with the instrument cabin; and an air exchange component is arranged at the inner upper part of the shaft, and the air exchange component is used for enabling air for sealing the shaft to obtain power under the action of wave energy, forcing the air in the instrument cabin to finish one-time air suction and exhaust air exchange work at each wave peak and wave valley along with the wave energy, and circularly exhausting humid air in the instrument cabin. An exhaust and suction passage is formed from the shaft to the mast barrel from bottom to top through wave energy, convection is formed inside and outside the buoy, temperature inside and outside the instrument cabin is exchanged in time, condensate water is reduced, and a reliable environment is provided for normal operation of equipment in the instrument cabin.
