The utility model belongs to the technical field of channel warning, and discloses a port channel safety warning device which comprises a warning mechanism which comprises a floating plate capable of floating on the water surface, a balance rod installed below the floating plate, a balancing weight installed below the balance rod, a rotatable lamp box arranged above the floating plate, and a light source arranged in the lamp box. Compared with the prior art, the floating plate structure has the advantages that the warning mechanism is designed, the floating plate structure is arranged on an open water surface before a ship enters a navigation channel, when wind blows, the rotating blades on the top of the lamp box drive the lamp box to rotate synchronously, and therefore the ship can be warned. The warning lamps on the four sides alternately face different directions to achieve dynamic indication, compared with a traditional ashore warning device, the mechanism warns on the water surface of a channel entrance in advance, a ship can be seen from a long distance, sufficient time is provided for a driver to adjust the course, and the dynamic warning lamps have more visual impact force and can rapidly attract attention in the complex port environment at night.
