The invention discloses a cylindrical sound beacon electrode cover sand blasting tool, and belongs to the technical field of cylindrical sound beacons. The cylindrical sound beacon electrode cover sand blasting tool is characterized in that an electrode cover is placed in a combined body of an upper cover, a lower cover and a locking ring to protect the part of the electrode cover which does not need to be subjected to sand blasting, and the end cylinder face of an electrode end face protection rod is in contact with the upper end face of an electrode to protect the upper end of the electrodewhich does not need to be subjected to sand blasting; the electrode end face protection rod is installed on a supporting plate through a thread, the supporting plate is supported by two supporting screws, and the two supporting screws are installed on two screw holes in the diameter direction of the upper end face of the upper cover. The cylindrical sound beacon electrode cover sand blasting toolhas the advantages of being simple in structure and convenient to use, and the problem that sand blasting parts and non-sand-blasting parts are inconsistent when the sound beacon electrode cover is produced is solved. The cylindrical sound beacon electrode cover sand blasting tool is mainly used for sand blasting treatment during production of the cylindrical sound beacon electrode cover.
