Assembly-type steel net cage frame

The utility model relates to an assembly-type steel net cage frame, belongs to the technical field of net cage culture of fish, and adopts the technical scheme that the assembly-type steel net cage frame mainly comprises angle iron frames, steel plate connecting pieces, high-density foam bricks, a bamboo-board sidewalk and rubber pads, and is mainly characterized in that steel plate connecting pieces are welded on three surfaces of each of the two ends of each angle iron frame with the length of 7000 mm, and steel plate connecting pieces are welded on the left side surface and the right side surface of two ends of each angle iron frame with the length of 6000 mm; and according to the requirement of net cage culture, every four angle iron frames, including two angle iron frames with the length of 7000 mm and two angle iron frames with the length of 6000 mm, can be randomly connected and assembled into a group, the group of frames can be connected with a second group of frames side by side to form a fish row by utilizing the steel plate connecting piece on each third surface of each angle iron frame with the length of 7000 mm, and random connection can be performed for the size of the fish row as required, so that the problems that the traditional net cage cannot be moved easily in the original water area and is relocated to another place difficultly are completely solved.
