[0030] In specific use, the working principle of the utility model is as follows:
[0031] In the stage of putting into use, the staff first puts the floating plate 11 on the water surface, and then puts the bottom block 18 into the water, so that it sinks to contact with the bottom of the water. The bottom block 18 restricts the floating plate 11 by the connecting rope, effectively avoids the large position deviation of the floating plate 11 due to factors such as water flow and wave, and the balance rod 19 connected below the floating plate 11 plays a key role by virtue of its own gravity, adjusts the gravity center of the floating plate 11, and makes the floating plate 11 always maintain a horizontal and stable floating posture. When the wind blows, the rotating blade 13 installed on the top of the lamp box 14 can rotate to meet the wind. The rotating blade 13 drives the connecting shaft to rotate through the rotating block 12, and then drives the lamp box 14 to rotate synchronously. In this process, the warning light 15 installed on the four sides of the lamp box 14 faces different directions alternately in the form of dynamic indication, clearly transmits warning signals to passing ships. At the same time, when the lamp box 14 rotates, the inner side of the bearing 115 is driven to rotate by the driven shaft 116, so as to ensure the stability of the rotating shaft line. The connecting rod 113 drives the universal ball 114 to smoothly roll along the ring groove 112 path, so as to reduce the friction resistance in the rotating process of the lamp box 14, and make the lamp box 14 easily rotate in a slight wind environment.
[0032] When the lamp box 14 and the warning light 15 need to be disassembled and repaired, the staff rotates the positioning bolt 118 to make it separate from the vertical rod 16 from above, and then takes up the side frame 17 to make it separate from the vertical rod 16. In this way, the lamp box 14 can be smoothly disassembled from above the floating plate 11, which facilitates the repair or replacement of the lamp box 14 and the warning light 15. When reinstallation is needed, the side frame 17 can be contacted with the supporting plate 117 according to the reverse operation steps.
[0033] If a ship collision event occurs, the impact force will first act on the protective outer pad 22. The protective outer pad 22 first absorbs and buffers the energy to complete the primary buffering. After the primary buffering, the remaining impact force is conducted to the pressing rod 24 along the arc-shaped baffle 21. The pressing rod 24 pushes the limiting plate 26 to extrude the buffer spring 25. In this process, the buffer spring 25 cleverly converts the impact force into elastic potential energy, further buffers the impact force, weakens the impact force intensity transmitted to the floating plate 11, and effectively reduces the damage of the floating plate 11 when it is subjected to the ship collision.
