The invention relates to a protection method for an ocean platform pile leg strain monitoring device, and the method comprises the following steps: marking a protection cover pedestal welding region on a platform pile leg according to the installation position of a fiber bragg grating strain sensor, and carrying out the grinding of the installation position of the fiber bragg grating strain sensorand the protection cover pedestal welding region; sequentially welding the fiber bragg grating strain sensor and the protection cover base on the platform pile leg, ensuring that the fiber bragg grating strain sensor is positioned at the central position in the protection cover pedestal during welding, and performing full welding on the protection cover pedestal and the platform pile leg to formprimary protection; after welding is completed, connecting an external data optical fiber into the protection cover from the wire inlet locking connector and the wire outlet locking connector, performing fiber melting treatmen
