Description

An Amphibious drone and A Deck for taking off and landing therof}

The present invention relates to drones and take-off and landing decks for drones that can be operated for various purposes, such as exploration or inspection, on land as well as in particularly poor water and climate.

In general, a drone is an unmanned aerial vehicle in which the aircraft recognizes and judges the surrounding environment autonomously and operates autonomously according to a remote control or a pre-programmed program without the operator boarding the aircraft. It is not only intended for video shooting but also has infinite scalability that can be used in all industries including fire fighting and lifesaving.

In recent years, drones have been used for various survey operations at sea, searching for missing persons, and inspecting various facilities including aquatic solar and aquatic wind power generation facilities. The disadvantage of drones is that flight time is limited due to the limited capacity of the battery. It should be only a few minutes long, so it is necessary to return to the land to replace the battery, and if the drone falls into the sea, the damage caused by flooding will sink as well as sink into the water.

On the other hand, when returning a drone that was in flight at sea to the ship, the deck of the ship should be wide enough, accordingly the size of the ship has a problem, and if the ship is tilted or rocked by the waves drone landing on the deck There was also a risk of being damaged or flipped to one side.

Control server for managing the various information recorded in the; It consists of a single flight can be obtained underwater information along with the sea information in one flight can increase the efficiency of ocean observation, survey and monitoring, but the limitation of flight time and frequency Due to the short activity time, the activity area (radius) could not be extended.

Patent Document 2, 'Drone's Return Home Mode Implementation System and Method', when a drone receives a return home mode command signal to return to a specific unmanned vessel, receives unmanned vessel information from an unmanned vessel and photographs an unmanned vessel. Although it is configured to wirelessly charge the drone after the drone is correctly returned to the wireless charging station of the unmanned ship, there was a problem that the operation of the unmanned vessel and its implementation and the drone landing and wireless charging are not easy to actually implement.

Patent document 3, 'Electromagnet-based take-off and landing device for rough environment operation of ship's aircraft', converts the drone's leg stand into an electromagnet to allow the drone to take off and land stably in ships. Foldable net drone collection device; has the advantage of stable collection of drones in a ship having a narrow space of the rough marine environment accompanied by waves and strong winds, but this is suitable for small drones, but for landing medium and large drones There was a limitation that was not suitable.
