The landing process of the unmanned aerial vehicle is opposite to the above-mentioned takeoff process, that is, after the control module on the floating platform 100 receives a return command sent by the unmanned aerial vehicle 300 through the wireless communication module, the control module firstly controls the hatch opening and closing device 106 to open the safety hatch 105, and selects an empty turntable 210 from the storage and transportation device 230 through the lifting platform 220 to lift to the buoy deck 101. The drone 300 initially hovers above the lift 220 and then is guided to slowly and safely land by the buoy attitude observed by the high-precision attitude sensor 240 on the floating platform 100. The horn mouth type anti-collision net 303 installed on the support legs of the unmanned aerial vehicle 300 facilitates the docking of the unmanned aerial vehicle 300 with the locking mechanism 250 on the turntable 210. After the unmanned aerial vehicle 300 is docked with the locking mechanism 250 on the turntable 210, the control module controls the locking mechanism 250 on the turntable 210 to lock and fix the unmanned aerial vehicle 300, and controls the locking mechanism 226 on the lifting platform 220 to lock the turntable 210 on the lifting platform 220. Then, the control module controls the lifting platform 220 to descend to the butt joint position of the storage and transportation device 230 and the turntable 210, and then controls the lifting platform 220 to unlock the turntable 210, and simultaneously controls the locking mechanism 236 on the storage and transportation device 230 to act, so that the turntable 210 is locked and fixed on the storage and transportation device 230 and is transported to a designated storage position. Finally, the control module controls the hatch opening and closing device 106 to close the safety hatch 105 on the buoy deck 101, so that the unmanned aerial vehicle 300 is stored in a closed mode.

7. The floating platform unmanned aerial vehicle take-off and landing device of claim 5, wherein the lifting platform comprises a table top for carrying the turntable, and the locking mechanism on the lifting platform is arranged on the top surface of the table top; the bottom surface of the table top is provided with a rocker, the rocker is connected with a crank, the crank is connected with a lifting motor, and the lifting motor drives the rocker to rotate by driving the crank to rotate so as to drive the table top to lift; the table top is assembled with a guide rod in a sliding mode, and the guide rod is vertically arranged in the inner cabin of the buoy.

8. The floating platform drone take-off and landing device of claim 7,

the crank and the rocker are in an H-shaped structure;

and the locking mechanism on the lifting platform and the locking mechanism on the semicircular bracket are linear motors.

9. The floating platform drone take-off and landing device of any one of claims 1 to 8, wherein the drone locking mechanism includes:

the upright post is of a hollow structure, the peripheral side wall of the upright post is provided with a through hole, and a reed is arranged in the through hole;

the locking block is hinged with the upright post, the hinged shaft is positioned at the position of the through hole, a bulge is formed on the inner side of the locking block, and the reed is pressed against the locking block;

the upper part of the push rod extends into the upright post, and the lower part of the push rod is provided with a rack structure; a push disc vertical to the push rod is formed at the upper part of the push rod, and the push disc is abutted against the bottom of the bulge;

a locking motor, wherein a rotating shaft of the locking motor is connected with a gear, and the gear is meshed with a rack structure formed on the push rod; when the locking motor drives the push rod to move upwards through the gear, the push disc pushes the protrusion upwards to enable the locking block to partially extend out of the through hole so as to lock the unmanned aerial vehicle; when the locking motor moves down through the gear drive push rod, the reed is pressed against the locking block, so that the locking block resets and is retracted into the stand column to unlock the unmanned aerial vehicle.
