The utility model provides a multifunctional navigation aid device which comprises a navigation aid assembly, a duckweed assembly and a power assembly. The duckweed assembly comprises a cabin body, a duckweed assembly and a balance weight part, the duckweed assembly is movably connected with the peripheral side of the cabin body, and the balance weight part is connected with the bottom of the cabin body; the navigation aiding assembly is arranged at the top of the cabin body; and the power assembly is arranged at the bottom of the cabin body. The multifunctional navigation aid device not only can resist sea surface storm waves, but also can automatically return to the original position when position deviation occurs.

The patrol rescue unmanned aerial vehicle comprises an unmanned aerial vehicle body, a protection part is installed at the bottom end of the unmanned aerial vehicle body and can be used for protecting a life buoy, three sets of first stand columns are installed in an inner cavity of the protection part circumferentially at equal intervals, and each set of first stand columns is connected with a set of racks in a limiting and sliding mode. The life buoy can be protected by the aid of the mounted protective part, wind influence on the life buoy is reduced, and the three groups of racks can be driven by the driving component to slide along the first vertical column in a limited manner, extend to the position below the life buoy and limit the life buoy, so that the life buoy can be prevented from being separated from the protective part. The life buoy can be prevented from being separated from the inner cavity of the protection part, the life buoy can be protected and limited, the unmanned aerial vehicle body is more stable to carry, when the unmanned aerial vehicle body flies over a water area with large storm waves, the life buoy is not prone to being affected by wind power, the flying attitude of the unmanned aerial vehicle body is not prone to being unstable, and the operation difficulty and danger are reduced.
