Abstract

To solve a problem in which the buoyancy obtained by a drone's propulsion device alone is insufficient for buoyancy when a drone is loaded with a heavy object, and therefore, flight is impossible, and cause the drone to fly while generating the power necessary for the drone flight when the drone is not loaded with a heavy object and can fly only with the buoyancy obtained by the drone's propulsion device.SOLUTION: A drone including a hydrogen balloon for storing hydrogen gas, and a hydrogen fuel cell that uses hydrogen gas as fuel to generate electricity can fly while generating power required for the drone flight by flying while obtaining buoyancy with the hydrogen balloon filled with hydrogen gas in order to enable flight even when the buoyancy obtained by a drone's propulsion device is insufficient when flying while carrying a heavy object, and generating electricity with the hydrogen fuel cell by using the hydrogen gas in the hydrogen balloon as fuel when not loading a heavy object.SELECTED DRAWING: Figure 1

Description

The present invention relates to a hydrogen balloon and a drone with a hydrogen fuel cell, which carries a hydrogen balloon for flying while carrying a heavy object, and which flies while generating power with a hydrogen fuel cell.

The problem to be solved is that when flying with a heavy load on the drone, the buoyancy obtained by the drone's propulsion device is insufficient for buoyancy, and the problem when the flight is impossible is solved, and the drone If you can fly only with the buoyancy provided by the drone's propulsion device without loading heavy objects, the drone is at the point of flying while generating the power necessary for the drone to fly.

The present invention is a drone equipped with a hydrogen balloon for storing hydrogen gas and a hydrogen fuel cell for generating electric power using hydrogen gas as a fuel, and the buoyancy obtained by a propulsion device provided in the drone when flying while carrying a heavy object In order to enable flight even when there is a shortage, the hydrogen balloon filled with hydrogen gas flies while gaining buoyancy, and when no heavy object is loaded, the hydrogen gas in the hydrogen balloon is used as fuel The most important feature is that the drone can generate power by using the battery to generate the power necessary for the drone to fly.

Since the hydrogen balloon and the drone with hydrogen fuel cell of the present invention can obtain buoyancy not only by the propulsion device provided in the drone but also by the hydrogen balloon itself, flight is not possible only by the buoyancy of the propulsion device provided by the drone. If possible, it will be possible to fly, and if sufficient buoyancy can be obtained with only the propulsion device of the drone, it will be possible to fly using hydrogen gas in the hydrogen balloon as fuel and a hydrogen fuel cell to generate electricity. , There is an advantage that the drone itself does not have to be equipped with a large amount of batteries.

The side view of the drone with a hydrogen balloon and a hydrogen fuel cell which was equipped with the hydrogen balloon which filled hydrogen gas in the upper part, and was equipped with the hydrogen fuel cell in the lower part, and was connected with the drone of the center part. (Example 1)

If the drone needs buoyancy, it will fly while obtaining the buoyancy of the hydrogen balloon, and if it does not need buoyancy, the objective is to fly while generating electricity with a hydrogen fuel cell based on the hydrogen gas in the hydrogen balloon. With the number of parts, it was realized without impairing the functions of the drone.

FIG. 1 is a side view of one embodiment of the device of the present invention, 1 is a hydrogen balloon, 2 is a drone propeller, 3 is a drone body and control unit, and 4 is a hydrogen fuel cell.

The hydrogen balloon 1 may be made of any material and shape as long as it satisfies the purpose of hermetically storing hydrogen gas. Further, the arrangement and connection of 1 hydrogen balloon, 2 drone propulsion device, 3 drone body, and 4 hydrogen fuel cell are arbitrary as long as they do not interfere with flight.

When flying between a departure point and a destination while loading a heavy load on a drone, and when arriving at the destination, removing the heavy load from the drone and then returning to the starting place, the outbound route (while loading the heavy load) In buoyancy provided by the drone's propulsion device alone, buoyancy is not enough to solve the problem when flight is not possible, and the drone generates the power necessary for the flight on the return trip (without heavy objects) By enabling flight while enabling efficient transportation of heavy objects, it is expected to be utilized in industrial fields such as the transportation industry.

In a drone equipped with a hydrogen balloon to store hydrogen gas and a hydrogen fuel cell that uses hydrogen gas as a fuel, the buoyancy obtained by the drone's propulsion device is insufficient when flying while carrying a heavy object. In order to enable flight even in the case, the hydrogen balloon filled with hydrogen gas flies while obtaining buoyancy, and when no heavy object is loaded, the hydrogen gas in the hydrogen balloon is used as fuel to generate electricity with the hydrogen fuel cell. As a result, the drone is capable of flying while generating the power necessary for the drone's flight by itself, and a drone with a hydrogen balloon and hydrogen fuel cell.
