When the signal is received, the valve body 2363b of the solenoid valve 2363a for the door may be introduced to open the first and second doors 2161 and 2162.

As described above, the unmanned aerial vehicle marine recovery apparatus 100, 400, 2100 according to the embodiments of the present invention may have the following effects.

According to one or another embodiment of the present invention, since the technical configuration including the air bowl 110 and the gas injector 120 is provided, the gas injector 120 is expanded in the form of a bowl. The unmanned aerial vehicle 10 may be seated on the air bowl 110 deployed at sea near the ship, so that the unmanned aerial vehicle 10 may be recovered at sea regardless of the size of the ship. In particular, since the air bowl 110 is provided in the unmanned aerial vehicle 10 and is unfolded to seat the unmanned aerial vehicle 10 on the air bowl 110, it is simpler than the technology of the conventional retrieval apparatus combined with a ship. The configuration and operation can prevent not only the recovery of the unmanned aerial vehicle 10 but also the unmanned aerial vehicle 10 from getting into the sea.

Further, according to another embodiment of the present invention, since the technical configuration including the air cover 2110, the gas injector 2120, the tension line 2130, and the parachute 2140 is provided, the gas injector 2120 The unmanned aerial vehicle 10 is collected on an air cover 2110 deployed in the sea near the ship in the form of a crepe while being expanded by), and together with the tension line by the reaction force of the parachute 2140 acting in the opposite direction of the flight direction. As the 2130 is pulled out, the unmanned aerial vehicle 10 captured in the air cover 2110 may be entirely surrounded by the air cover 2110, so that the unmanned aerial vehicle 10 may be recovered at sea regardless of the size of the vessel. . In particular, since the air cover 2110 surrounds the unmanned aerial vehicle 10 as a whole, the unmanned aerial vehicle 10 as well as the recovery of the unmanned aerial vehicle 10 with a simple configuration and operation compared to the technology of the conventional recovery device that is combined with the vessel. Can prevent getting into the sea.

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided. It belongs to the scope of rights.

Since the present invention relates to an unmanned aerial vehicle marine recovery apparatus can be applied to recover the unmanned aerial vehicle at sea, there is industrial applicability.
