Description

External Hydrogen Tank Apparatus for Drone}

The present invention relates to an external hydrogen fuel tank device used as an auxiliary power source for a drone. It is provided with an external hydrogen fuel tank capable of using extra hydrogen fuel in addition to the hydrogen fuel built into the drone, and hydrogen from the hydrogen fuel tank built into the drone is provided. This relates to an external hydrogen fuel tank device for drones that enables continuous drone operation by supplying power using additional hydrogen fuel stored in the external hydrogen fuel tank when the fuel is exhausted.

In general, a drone is a type of unmanned aircraft that flies in the sky by rotating multiple propellers using battery power. It flies by remote control or autonomous flight control without a pilot on board, and is used for filming, reconnaissance, etc. It refers to one of the unmanned aircraft that performs missions that are difficult or dangerous to perform directly by humans, such as cargo transportation and radiation monitoring.

Recently, drones are equipped with cameras, sensors, communication systems, etc., and products capable of self-controlling posture without difficult operation have been developed, making it easy for even unskilled people to use them in professional fields such as military unmanned aerial vehicles or broadcasting unmanned aerial vehicles. It is rapidly spreading and being used by the general public, and in recent years, it is being used for companies, media, and individuals. For example, newspapers, broadcasting industries, and film production companies are using drones as filming devices, and the delivery industry plans to use drones for actual delivery services within a few years. In particular, IT companies such as Google, Facebook, and Amazon have recently invested heavily in drone development, and among them, Amazon has unveiled a delivery system using drones to automate inventory management and distribution systems. In other words, a large number of researchers who develop drones have been hired to provide distribution services in which drones replace the work done by delivery staff.

Meanwhile, these drones have flight as their basic operation and use batteries to easily supply the power needed for operation, so the operating time is limited depending on the capacity of the battery. Therefore, in order to perform the various missions mentioned above, a stable flight time of the drone must be secured. To this end, in order to increase the amount of energy source provided in the drone, the volume and weight of the secondary battery used as a battery increases as the capacity is increased. A problem has arisen, which means that the size of the lift generated from the rotor for flight must be increased, and the size of the rotor that generates lift and the driving part that drives the rotor also increases, resulting in an increase in the overall weight and volume of the drone. will result in

Therefore, there is a need to develop technologies that can increase flight and mission performance times without significantly increasing the weight of the drone, and one of them is a hydrogen fuel cell drone using hydrogen fuel.

However, hydrogen fuel cell drones also have a structure that uses limited hydrogen fuel called a hydrogen fuel tank, and there are still problems with increasing flight and mission performance times.

Additional branches (not shown) may be included.

The drone 100 is an airplane or helicopter-shaped vehicle that flies without a person on board and is guided by radio waves. In particular, it is delivered to customers located in an area where drone delivery is possible or to a specific goods storage location (main line, storage, etc.). Goods can be delivered.

Figures 2 and 3 are block diagrams showing the configuration of an external hydrogen fuel tank device for a drone according to an embodiment of the present invention.

As shown in Figures 2 and 3, it consists of a drone 100 and an external hydrogen fuel tank device 200 for a drone connected to a hydrogen fuel supply pipe 300.

The internal hydrogen fuel tank 110 is provided in the main body of the drone 100 and stores a certain amount of hydrogen. At this time, the internal hydrogen fuel tank 110 may be a hydrogen storage cylinder made of carbon fiber storage alloy. This internal hydrogen fuel tank 110 further includes a charging port where hydrogen fuel is charged and a connection connector connected to the supply line of the fuel cell stack 120.

Meanwhile, the internal hydrogen fuel tank 110 can directly charge hydrogen fuel supplied from the external hydrogen fuel tank device 200 for drones. In this case, the internal hydrogen fuel tank 110 is used as an external hydrogen fuel for drones. It may further include a sub-charging port where hydrogen fuel supplied from the tank device 200 is charged.

The fuel cell stack 120 produces electricity by inducing a reaction between depressurized hydrogen fuel and external air. This fuel cell stack 120 is configured so that the supplied hydrogen fuel is separated into hydrogen ions and electrons in the catalyst of the anode, and the separated hydrogen ions pass to the air electrode (cathode) through the polymer electrolyte membrane. Additionally, oxygen supplied to the air electrode combines with hydrogen ions that enter the air electrode through an external conductor to generate water and generate electrical energy.

And the fuel cell stack 120 is configured to transmit the generated electrical energy to the driving unit 160 under the control of the control unit 130. Additionally, the fuel cell stack 120 may be configured to transmit the produced electrical energy to the battery 150 and store it under the control of the control unit 130.

The control unit 130 controls whether to supply electricity produced by the fuel cell stack 120 and the driving and flight of the drone. That is, the control unit 130 controls the supply and blocking of hydrogen fuel by controlling whether the internal hydrogen fuel tank 110 is opened and closed, and is configured to control the supply amount of hydrogen fuel according to the supply pressure of the supplied hydrogen fuel. . Additionally, the control unit 130 can control the degree of opening and closing of the internal hydrogen fuel tank 110.

It may be possible.

The DC-DC converter 140 rectifies and transforms commercial AC input based on the electricity produced by the fuel cell stack 120 and provides direct power input to the drone 100. For example, the DC-DC converter 140 converts to use a high voltage of up to 75V and has a switching noise of 50mV or less, decompresses the electrical energy transmitted from the fuel cell stack 120, and transmits it to the driver 160.

That is, the drone 100 may further include a camera for photographing the surroundings, a GPS module for detecting the current location, and a driving device for flight and movement.

As shown in FIG. 3, the external hydrogen fuel tank device 200 for a drone includes an internal hydrogen detection unit 210, a hydrogen supply conversion unit 220, an output control unit 230, an external hydrogen fuel tank 240, and an external hydrogen fuel tank 240. It may include a hydrogen detection unit 250 and an LED display unit 260. However, the external hydrogen fuel tank device 200 for a drone shown in FIG. 3 is according to one embodiment, and its components are not limited to the embodiment shown in FIG. 3, and some components are added as needed. , may be changed or deleted.

The external hydrogen fuel tank 240 is provided to be spaced a certain distance away from the main body of the drone 100, and a certain amount of stored hydrogen fuel leaks out to the drone 100 through the hydrogen fuel supply pipe 300 connected to one side. Hydrogen fuel can be supplied. At this time, the external hydrogen fuel tank 240 may not be connected to the main body of the drone 100 by any fixing means (including fixing and mounting), and may be a hydrogen storage cylinder made of carbon fiber storage alloy. This external hydrogen fuel tank 240 further includes a charging port where hydrogen fuel is charged, and a hydrogen fuel input port 270 connected to the hydrogen fuel output port 310 of the hydrogen fuel supply pipe 300.

At this time, the hydrogen fuel supply pipe 300 may be directly connected to the internal hydrogen fuel tank 110, but is not limited to this, and may be connected to the fuel cell stack 120 to produce electricity.

When the hydrogen fuel supply pipe 300 is directly connected to the internal hydrogen fuel tank 110, the hydrogen fuel stored in the external hydrogen fuel tank 240 is charged into the internal hydrogen fuel tank 110. In this case, the internal hydrogen fuel tank 110 can use the hydrogen fuel necessary for operation of the drone 100 and simultaneously charge the hydrogen fuel from the external hydrogen fuel tank 240. Therefore, when the hydrogen fuel stored in the external hydrogen fuel tank 240 is charged into the internal hydrogen fuel tank 110, the hydrogen fuel stored in the internal hydrogen fuel tank 110 is always fully filled. can be maintained.

Additionally, when the hydrogen fuel supply pipe 300 is connected to the fuel cell stack 120, the external hydrogen fuel tank 240 and the internal hydrogen fuel tank 110 operate the stored hydrogen fuel independently of each other. In this case, the method of operating independently from each other will be explained in detail below.

The internal hydrogen detection unit 210 detects the capacity of hydrogen fuel stored in the internal hydrogen fuel tank 110 provided in the main body of the drone 100. To this end, a sensor unit may be provided inside the internal hydrogen fuel tank 110 to measure the capacity of hydrogen fuel, and the capacity of hydrogen fuel detected by the sensor unit may be used to store the hydrogen fuel in the internal hydrogen fuel tank 110. The capacity of hydrogen fuel can be detected in real time.

The external hydrogen detection unit 250 detects the capacity of hydrogen fuel stored in the external hydrogen fuel tank 240. For this purpose, a sensor unit may be provided inside the external hydrogen fuel tank 240 to measure the capacity of hydrogen fuel, and the capacity of hydrogen fuel detected by the sensor unit may be used to store the hydrogen fuel in the external hydrogen fuel tank 240. The capacity of hydrogen fuel can be detected in real time.

The hydrogen supply switching unit 220 detects the remaining amount of hydrogen fuel stored in the internal hydrogen fuel tank 110 detected by the internal hydrogen detection unit 210, and when it is measured to be less than the set value, it supplies power to the drone to the external hydrogen fuel. A control signal is output to convert the hydrogen fuel stored in the tank 240 into the hydrogen supply of the drone 100.

In another embodiment, the hydrogen supply switching unit 220 detects the external hydrogen fuel tank 240 (the hydrogen fuel output port 310 of the hydrogen fuel supply pipe 300 and the hydrogen fuel input port 270 are connected). (detected through a sensor), stops using the hydrogen fuel stored in the internal hydrogen fuel tank 110, and switches the hydrogen fuel stored in the external hydrogen fuel tank 240 to be supplied to the drone 100. Control signals can be output. And the hydrogen supply switching unit 220 detects the remaining amount of hydrogen fuel stored in the external hydrogen fuel tank 240 detected by the external hydrogen detection unit 250 and measures it as less than the set value, or the external hydrogen fuel tank ( 240) is detected (sensed through a sensor when the hydrogen fuel output port 310 and the hydrogen fuel input port 270 of the hydrogen fuel supply pipe 300 are separated), the power supply to the drone 100 is switched to the internal hydrogen A control signal that switches the hydrogen fuel stored in the fuel tank 110 to be supplied to the drone 100 can be output.

In this way, the hydrogen supply conversion unit 220 is a hydrogen fuel used to supply power to the drone 100, and sets either the internal hydrogen fuel tank 110 or the external hydrogen fuel tank 240 as priority. Hydrogen fuel stored in the high-ranking fuel tanks 110 and 240 can be processed so that they can be used first.

However, when the hydrogen fuel supply pipe 300 is directly connected to the internal hydrogen fuel tank 110, the hydrogen fuel stored in the internal hydrogen fuel tank 110 is used, and the external hydrogen fuel tank 240 is supplied as much as the hydrogen fuel used. ), preventing wasted time in which the drone 100 cannot be operated due to the hydrogen fuel charging time of the internal hydrogen fuel tank 110, which cannot be separated from the drone 100, and moves after transporting the product. It is desirable to guarantee the operating time of the drone 100.

In addition, when the external hydrogen fuel tank 240 and the internal hydrogen fuel tank 110 are operated independently of each other, the hydrogen fuel stored in the external hydrogen fuel tank 240 is used first, so that the drone 100 ) to prevent wasted time in which the drone 100 cannot be operated due to the hydrogen fuel charging time of the internal hydrogen fuel tank 110, which cannot be separated from the desirable.

The output control unit 230 controls whether to open and close the external hydrogen fuel tank 240 and the internal hydrogen fuel tank 110 based on the control signal output from the hydrogen supply switching unit 220, and controls the external hydrogen fuel tank ( 240) and controls the supply and supply interruption of hydrogen fuel stored in the internal hydrogen fuel tank 110.

Accordingly, the control unit 130 configured within the drone 100 controls the hydrogen fuel supplied from the internal hydrogen fuel tank 240, and uses the hydrogen fuel supplied from the external hydrogen fuel tank 240 to operate the fuel cell. The operation of the stack 120 is controlled to produce electrical energy.

The LED display unit 260 displays the capacity of hydrogen fuel stored in the external hydrogen fuel tank 240 detected by the external hydrogen detection unit 250 in numerical values, scales, area graphs, etc. so that the user can check. In addition, the LED display unit 260 can display hydrogen fuel capacity and charge and discharge status information of the external hydrogen fuel tank 240, as well as information such as whether or not it is electrically connected to the drone 100.

Meanwhile, in FIG. 3, the internal hydrogen detection unit 210, the hydrogen supply switching unit 220, and the output control unit 230, which are included as an internal configuration of the external hydrogen fuel tank device 200 for a drone, are located inside the drone 100. It may be configured.

Through this configuration, unlike conventional drones that operate using only the hydrogen fuel stored in the internal hydrogen fuel tank 110 as the power of the drone 110, the hydrogen fuel stored in the external hydrogen fuel tank device 200 is additionally operated. By being able to use it as auxiliary power for the drone 110, the drone's loitering flight time and mission performance radius can be dramatically improved.
