Summary of the Invention

Problems to be Solved by the Invention

[0004] However, when winding a cushioning material around the fuel tank, a space for the cushioning material and components such as brackets for holding the cushioning material around the fuel tank are required. In addition, there is a problem that an extra mass corresponding to the cushioning material and the components is added. Furthermore, there is a problem that the number of components increases due to the components.

[0005] The present invention has been made to solve such problems, and an object thereof is to provide a drone that can more suitably protect a fuel tank.

Means for Solving the Problems

[0006] A drone according to a first aspect of the present invention includes a fuel tank filled with fuel and a chemical agent tank filled with a chemical agent, and the chemical agent tank has a shape that surrounds at least a part of an outer surface of the fuel tank.

Effects of the Invention

[0007] According to the first aspect of the present invention, since the spraying agent tank surrounds at least a portion of the outer surface of the fuel tank, the spraying agent tank can act as a buffer covering the fuel tank. This eliminates the need for a separate buffer to protect the fuel tank, resulting in space savings, reduced unnecessary mass, and a reduction in the number of parts. Thus, a drone that can more effectively protect the fuel tank can be provided. [Brief explanation of the drawing]

[0008] [Figure 1] This is a schematic diagram showing a drone according to Embodiment 1. [Figure 2] This is a schematic diagram showing a drone according to Embodiment 2. [Modes for carrying out the invention]

[0009] Embodiment 1 Embodiments of the present invention will be described below with reference to the drawings. The drone 100 according to this first embodiment is a fuel cell drone equipped with a fuel cell and using the fuel cell as a power source. As shown in Figure 1, the drone 100 includes a fuel tank 101 filled with hydrogen as fuel and a spraying agent tank 102 filled with spraying agent. The drone 100 further includes sensors (not shown) such as an acceleration sensor, angular velocity sensor, speed sensor, altitude sensor, and direction sensor, a propeller 103, a motor (not shown) that rotates the propeller 103, and a flight control unit (not shown) that controls the flight of the drone 100 so that it flies along a predetermined flight route based on acceleration data, angular velocity data, speed data, altitude data, and direction data input from the sensors.

[0010] The fuel tank 101 has a roughly cylindrical shape. In the example shown in Figure 1, the drone 100 is equipped with two fuel tanks 101, but the number of fuel tanks 101 mounted on the drone 100 is not limited to two. Furthermore, the shape of the fuel tank 101 is not limited to a roughly cylindrical shape, but may be a roughly triangular prism, a roughly rectangular prism, a roughly polygonal shape, etc.

[0011] The spraying agent tank 102 has a shape that surrounds at least a portion of the outer surface of the fuel tank 101. In the example shown in Figure 1, the outer shape of the spraying agent tank 102 has a hole into which the fuel tank 101 can be inserted. In this case, the hole in the spraying agent tank 102 covers the entire circumferential surface of the fuel tank 101. In the example shown in Figure 1, since there are two fuel tanks 101 mounted on the drone 100, the spraying agent tank 102 also has two holes, but the number of fuel tanks 101 mounted on the drone 100 and the number of holes in the spraying agent tank 102 are not limited to this. For example, multiple fuel tanks 101 may be inserted in series into one hole in the spraying agent tank 102.

[0012] Examples of sprays to be charged into the spray tank 102 include pesticides and fertilizers. Furthermore, the main component of the spray filled into the spray tank 102 is preferably water, a non-flammable liquid, or a flame-retardant liquid. The spray may also be a fire extinguishing agent or the like.

[0013] As described above, in the drone 100 according to Embodiment 1, since the spraying agent tank 102 surrounds the outer surface of the fuel tank 101, the spraying agent tank 102 can act as a buffer covering the fuel tank 101. This eliminates the need for a separate buffer to protect the fuel tank 101, resulting in space savings, reduction of unnecessary mass, and reduction of the number of parts. Therefore, a fuel cell drone 100 that can more effectively protect the fuel tank 101 can be provided.

[0014] Furthermore, if the main component of the spraying agent filled in the spraying agent tank 102 is water, a non-flammable liquid, or a flame-retardant liquid, it will not exacerbate a fire that may occur if the drone 100 crashes. Therefore, the safety of the drone 100 can be improved. A similar effect can be obtained if the spraying agent is a fire extinguishing agent.

[0015] Embodiment 2 Figure 2 shows the drone 200 according to Embodiment 2. As shown in Figure 2, the configuration of the drone 200 is the same as that of the drone 100, except for the spraying tank 202. Therefore, components of the drone 200 that are the same as those of the drone 100 are given the same reference numerals as those of the drone 100, and their descriptions are omitted.

[0016] The spraying agent tank 202 has a shape that surrounds at least a portion of the outer surface of the fuel tank 101. In the example shown in Figure 2, the outer shape of the spraying agent tank 202 has a recess into which the fuel tank 101 can be fitted. In this case, the recess of the spraying agent tank 202 covers a portion of the circumferential surface of the fuel tank 101. The fuel tank 101 and the spraying agent tank 202 are fixed on the base portion 204 of the drone 200, and the opening side of the recess of the spraying agent tank 202 is covered by the base portion 204. Therefore, the circumferential surface of the fuel tank 101 that is not covered by the spraying agent tank 202 is covered by the base portion 204. In the example shown in Figure 2, since there is one fuel tank 101 mounted on the drone 200, the spraying agent tank 202 also has one recess, but the number of fuel tanks 101 mounted on the drone 200 and the number of recesses in the spraying agent tank 202 are not limited to this. For example, multiple fuel tanks 101 may be fitted in series into one recess of the spraying agent tank 202.

[0017] As described above, in the drone 200 according to this second embodiment, the spraying agent tank 202 and the base portion 204 surround the outer surface of the fuel tank 101, so the spraying agent tank 202 can act as a cushioning material covering the fuel tank 101. This eliminates the need for cushioning material to protect the fuel tank 101, resulting in space savings, reduction of unnecessary mass, and reduction of the number of parts. Therefore, a fuel cell drone 200 that can more effectively protect the fuel tank 101 can be provided.

[0018] It should be noted that the present invention is not limited to the embodiments described above, and can be modified as appropriate without departing from the spirit of the invention. For example, the fuel filled in the fuel tank 101 is not limited to hydrogen, but may be a fuel gas such as natural gas, or a liquid fuel such as gasoline. [Explanation of symbols]
