Description

The present invention relates to a container for a flying object such as a balloon or an airship.

There are flying objects such as balloons and airships equipped with cabins that are containers for accommodating people (crew members). According to such a projectile, a person can move in the air.

For example, Patent Document 1 discloses a flying object including a cabin for accommodating a person. Patent Document 1 proposes a manned drone having a structure in which a drone body containing a person is suspended by a balloon and flies.

Japanese Unexamined Patent Publication No. 2020-9734

The higher the altitude of the projectile from the ground, the lower the ambient temperature. Therefore, the temperature of the wall surface of the cabin becomes lower than the temperature of the air inside the cabin of the flying object, the air in contact with the wall surface of the cabin is cooled, the water vapor contained in the air changes to water, and the inside of the wall surface. Dew may occur, which is a phenomenon that adheres to the air as dew.

When a part of the wall surface of the cabin is a window (a plate that transmits light), if dew condensation occurs on the window, it becomes difficult for the crew inside the cabin to see the outside of the cabin. Further, if dew condensation occurs on the wall surface of the cabin and the generated water infiltrates the electronic equipment or the like in the vicinity thereof, inconveniences such as failure of the inundated electronic equipment or the like may occur.

Further, the projectile may include a container containing a device such as a photographing device. Even in such a container, as in the case of the above-mentioned cabin, if dew condensation occurs on the inside of the wall surface of the container, the generated water may cause inconvenience such as failure of the device in the container.

Further, when the flying object is provided with a container accommodating the photographing device, the wall surface of the container entering the angle of view of the photographing device needs to be a window through which light is transmitted. When dew condensation occurs on this window, the image captured by the photographing device may be out of focus, or water droplets generated by the dew condensation may be reflected in the captured image.

In view of the above circumstances, the present invention provides means for reducing the probability of dew condensation occurring in the container provided in the projectile.

The present invention is a container included in the flying object, and the space inside the container body and the container body is different from the first small space for accommodating the contained object and the first small space. The partition plate is provided with a partition plate for partitioning from the small space of the above, and the partition plate is provided with the first small space and the partition plate so as to eliminate a pressure difference generated between the first small space and the second small space. It has one or more holes of a size that causes gas in and out between the second small space but does not cause gas convection between the first small space and the second small space. The volume of the gas in the first small space with respect to the area of the container body in contact with the gas in the first small space is the second with respect to the area of the container body in contact with the gas in the second small space. A container larger than the volume of gas in a small space is proposed as the first aspect.

Further, the present invention is a container included in the flying object, and the space inside the container body and the container body is different from the first small space for accommodating the contained object and the first small space. A portion of the container body having a partition plate partitioning the second small space and forming the second small space is formed between the second small space and the space outside the container body. Gas enters and exits between the second small space and the space outside the container body so as to eliminate the pressure difference, but between the second small space and the space outside the container body. A container having one or more holes having a size that does not cause gas convection is proposed as a second embodiment.

In the container according to the first or second aspect, at least a part of the container body and at least a part of the partition plate emit light so that light is transmitted from the outside of the container body to the first small space. The configuration of being transparent may be adopted as the third aspect.

Further, the present invention is a container included in the flying object, which includes a first container body for accommodating an object and a second container body for accommodating the first container body, and the first container. When the space inside the main body is defined as the first small space and the space between the first container body and the second container body is defined as the second small space, the first container body is the first container body . Gas enters and exits between the first small space and the second small space so as to eliminate the pressure difference generated between the small space 1 and the second small space, but the first As the fourth aspect, a container having one or more holes having a size that does not cause gas convection between the small space of No. 1 and the second small space is proposed.

[First Embodiment]
FIG. 1 is a diagram showing the overall configuration of the flying object 1 according to the first embodiment of the present invention. The flying object 1 includes a bulb 11 that contains a gas lighter than air such as helium, a container 12 that is suspended from the bulb 11 and flies, and one end is connected to the bulb 11 and the other end is connected to the container 12. A hanging rope 13 which is a plurality of cords to which the portions are connected and the bulb 11 is provided for suspending the container 12 is provided.

FIG. 2 is a diagram showing the configuration of the container 12. The container 12 has a container body 121 which is an airtight hollow box body for accommodating a crew member H1 and the like, and a small space S1 (an example of a first small space) and a small space inside the container body 121. A partition plate 122 for partitioning S2 (an example of a second small space) is provided.

The small space S1 is a space for accommodating the contents such as the crew member H1 and is filled with air containing oxygen having a concentration that allows the crew member H1 to breathe comfortably.

At least a part of the partition plate 122 transmits light. In the example of FIG. 2, the portion of the partition plate 122 in the range A is made of a material that transmits light (for example, transparent polycarbonate or acrylic resin). The portion of the partition plate 122 other than the range A is made of, for example, a fiber reinforced plastic, a plastic other than the fiber reinforced plastic, a light metal such as aluminum, or the like.

Further, at least a part of the container body 121 that forms the small space S2 transmits light. In the example of FIG. 2, the portion of the container body 121 in the range B is made of a material that transmits light (for example, transparent polycarbonate or acrylic resin). The portion of the container body 121 other than the range B is made of, for example, fiber reinforced plastic, plastic other than fiber reinforced plastic, light metal such as aluminum, and the like.

As described above, since the portion A of the partition plate 122 and the portion B of the container body 121 transmit light, the crew member H1 accommodated in the small space S1 can enter the small space S1 from the outside of the container 12. The outside of the container 12 can be visually recognized by the transmitted light.

The partition plate 122 has one or more fine holes H. The hole H causes a gentle gas inflow and outflow between the small space S1 and the small space S2. The hole H is small with the small space S1 so that when a difference occurs between the temperature of the gas in the small space S1 and the temperature of the gas in the small space S2, the pressure difference caused by the temperature difference is eliminated in a short time. Gas enters and exits between spaces S2. On the other hand, the hole H is not large enough to cause gas convection between the small space S1 and the small space S2. Therefore, it takes several minutes to several tens of minutes to eliminate the difference between the temperature of the gas in the small space S1 and the temperature of the gas in the small space S2.

Generally, as the flying object 1 rises in altitude (height from the ground) due to flight, the air around the container 12 becomes dilute and low in temperature. When the container body 121 is rapidly cooled from the outside by the flight of the flying object 1, the water vapor in the gas that comes into contact with the container body 121 from the inside is cooled by the container body 121 to become water, and water droplets are formed on the inner surface of the container body 121. That is, dew condensation is likely to occur in the container body 121.

However, the volume of the gas in the small space S1 with respect to the area of the container body 121 in contact with the gas in the small space S1 is larger than the volume of the gas in the small space S2 with respect to the area of the container body 121 in contact with the gas in the small space S2. .. Therefore, the rate at which the temperature of the gas in the small space S1 is cooled by the container body 121 is slower than the rate at which the temperature of the gas in the small space S2 is cooled by the container body 121. Further, as described above, gas hardly flows in and out between the small space S1 and the small space S2 due to convection.

As a result, there is a temperature relationship of (temperature in the small space S1)> (temperature in the small space S2)> (temperature in the space outside the container body 121). Therefore, both the temperature difference between the small space S1 and the small space S2 and the temperature difference between the small space S2 and the space outside the container body 121 are the differences in the temperature inside the container body 121 that occurs when the partition plate 122 is not present. It is smaller than the difference between the temperature and the temperature of the space outside the container body 121.

For the above reasons, the probability that dew condensation will occur on the partition plate 122 of the container 12 according to the present embodiment, and the present implementation, as compared with the probability that dew condensation will occur on the container body 121 if there is no partition plate 122. There is a low probability that dew condensation will occur in the portion of the container body 121 of the container 12 according to the form that forms the small space S2.

As described above, it takes a long time to eliminate the temperature difference between the small space S1 and the small space S2, but the pressure difference between the small space S1 and the small space S2 is quickly eliminated. Therefore, the partition plate 122 is not deformed or damaged by a strong force due to the pressure difference generated between the small space S1 and the small space S2.

As described above, according to the container 12 according to the present embodiment, dew condensation is unlikely to occur at least in the portion of the partition plate 122 and the container main body 121 that forms the small space S2.

[Second Embodiment]
The container 12 according to the second embodiment of the present invention will be described below. Similar to the container 12 according to the first embodiment, the container 12 according to the second embodiment is a container included in the flying object 1 (see FIG. 1), and is suspended from the bulb 11 via the hanging rope 13 and flies. do. The container 12 according to the second embodiment is different from the container 12 according to the first embodiment in the following points.
(1) The partition plate 122 of the container 12 according to the second embodiment does not have the hole H that the partition plate 122 of the container 12 according to the first embodiment has.
(2) The container body 121 of the container 12 according to the second embodiment has the same hole H as the partition plate 122 of the container 12 according to the first embodiment in the portion forming the small space S2. It has one or more holes I.

FIG. 3 is a diagram showing the configuration of the container 12 according to the present embodiment.

In the container 12 according to the present embodiment, when the temperature in the space outside the container body 121 suddenly drops as the flight altitude of the flying object 1 rises, between the small space S2 and the space outside the container body 121. While the pressure difference between the two is quickly eliminated, it takes time to eliminate the temperature difference between the small space S2 and the space outside the container body 121. As a result, as in the case of the container 12 according to the first embodiment, the temperature relationship of (temperature in the small space S1)> (temperature in the small space S2)> (temperature in the space outside the container body 121). Occurs.

As a result, for the same reason as described in the first embodiment, the probability of dew condensation occurring in the container body 121 (without the hole I) when the partition plate 122 is not present is compared with the present embodiment. The probability that dew condensation will occur on the partition plate 122 of the container 12 and the probability that dew condensation will occur on the portion of the container body 121 of the container 12 according to the present embodiment that forms the small space S2 are low.

As described above, it takes a long time to eliminate the temperature difference generated between the small space S2 and the space outside the container body 121, but it occurs between the small space S2 and the space outside the container body 121. The pressure difference disappears quickly. Therefore, the container body 121 (the portion forming the small space S2) is not deformed or damaged by the pressure difference generated between the small space S2 and the space outside the container body 121.

As described above, even in the case of the container 12 according to the present embodiment, dew condensation is unlikely to occur at least in the portion of the partition plate 122 and the container main body 121 that forms the small space S2.

[Third Embodiment]
The container 22 according to the third embodiment of the present invention will be described below. Similar to the container 12 according to the first embodiment, the container 22 according to the third embodiment is a container included in the flying object 1 (see FIG. 1), and is suspended from the bulb 11 via the hanging rope 13 and flies. do.

FIG. 4 is a diagram showing the configuration of the container 22. The container 22 has a first container main body 221 (an example of a first container main body) for accommodating an inclusion including a crew member H1 and an airtight second container main body 222 (a second container) for accommodating the first container main body 221. An example of the main body) and a heat insulating material 223 filled in a part of the space between the first container main body 221 and the second container main body 222 are provided. The container 22 does not have to be provided with the heat insulating material 223.

Hereinafter, the space inside the first container main body 221 is referred to as a small space S3, and the section between the first container main body 221 and the second container main body 222 is referred to as a small space S4.

The small space S3 and the small space S4 are filled with air containing oxygen having a concentration that allows the crew member H1 to breathe comfortably.

At least a part of the first container body 221 transmits light. In the example of FIG. 4, the portion of the first container main body 221 in the range C is made of a material that transmits light (for example, transparent polycarbonate or acrylic resin). The portion of the first container main body 221 other than the range C is made of, for example, fiber reinforced plastic, plastic other than fiber reinforced plastic, light metal such as aluminum, and the like.

Further, at least a part of the second container main body 222 transmits light. In the example of FIG. 4, the portion of the second container main body 222 in the range D is made of a material that transmits light (for example, transparent polycarbonate or acrylic resin). The portion of the second container main body 222 other than the range D is made of, for example, a fiber reinforced plastic, a plastic other than the fiber reinforced plastic, a light metal such as aluminum, or the like.

As described above, since the portion of the range C of the first container main body 221 and the portion of the range D of the second container main body 222 transmit light, the crew member H1 housed in the first container main body 221 is the first container. The outside of the container 22 can be visually recognized by the light transmitted from the outside of the second container main body 222 into the space inside the main body 221.

The first container body 221 has one or more fine holes J. The hole J causes a gentle gas in and out between the small space S3 and the first container main body 221 and the small space S4. The hole J is provided with the small space S3 so that when a difference occurs between the temperature of the gas in the small space S3 and the temperature of the gas in the small space S4, the pressure difference caused by the temperature difference is eliminated in a short time. Gas enters and exits between the small spaces S4. On the other hand, the hole J is not large enough to cause gas convection between the small space S3 and the small space S4. Therefore, it takes several minutes to several tens of minutes to eliminate the difference between the temperature of the gas in the small space S3 and the temperature of the gas in the small space S4.

Therefore, when the flight altitude of the flying object 1 rises and the container 22 is cooled from the outside, (temperature in the small space S3)> (temperature in the small space S4)> (in the space outside the second container body 222). Temperature), the relationship of temperature arises. Therefore, both the difference in temperature between the small space S3 and the small space S4 and the difference in the temperature between the small space S4 and the space outside the second container main body 222 occur when the first container main body 221 is absent. It is smaller than the difference between the temperature of the space inside the main body 222 and the temperature of the space outside the second container main body 222.

For the above reasons, dew condensation occurs in the first container body 221 of the container 22 according to the present embodiment, as compared with the probability that dew condensation occurs in the second container body 222 if the first container body 221 is not present. The probability and the probability that dew condensation will occur in the second container main body 222 of the container 22 according to the present embodiment are low.

As described above, it takes a long time to eliminate the temperature difference between the small space S3 and the small space S4, but the atmospheric pressure difference between the small space S3 and the small space S4 is quickly eliminated. Therefore, the first container main body 221 is not deformed or damaged by a strong force due to the pressure difference generated between the small space S3 and the small space S4.

As described above, according to the container 22 according to the present embodiment, dew condensation is unlikely to occur in the first container main body 221 and the second container main body 222.

(2) The second container body 222 of the container 22 according to the fourth embodiment has one or more holes K similar to the holes J possessed by the first container body 221 of the container 22 according to the third embodiment. are doing.
(3) The small space S4 according to the fourth embodiment is not filled with air containing oxygen having a concentration at which the crew member H1 can comfortably breathe.

FIG. 5 is a diagram showing the configuration of the container 22 according to the present embodiment.

In the container 22 according to the present embodiment, when the temperature in the space outside the second container body 222 sharply drops as the flight altitude of the flying object 1 rises, the outside of the small space S4 and the second container body 222 While the pressure difference between the space and the space is quickly eliminated, it takes time to eliminate the temperature difference between the small space S4 and the space outside the second container body 222. As a result, as in the case of the container 22 according to the third embodiment, the temperature (temperature in the small space S3)> (temperature in the small space S4)> (temperature in the space outside the second container main body 222). Relationship arises.

As a result, for the same reason as described in the third embodiment, it is compared with the probability that dew condensation occurs in the second container body 222 (without the hole K) if the first container body 221 is not present. The probability that dew condensation will occur in the first container main body 221 of the container 22 according to the present embodiment and the probability that dew condensation will occur in the second container main body 222 of the container 22 according to the present embodiment are low.

As described above, it takes a long time to eliminate the temperature difference generated between the small space S4 and the space outside the second container body 222, but the space outside the small space S4 and the second container body 222. The pressure difference that occurs between the two is quickly eliminated. Therefore, the second container body 222 is not deformed or damaged by a strong force due to the pressure difference generated between the small space S4 and the space outside the second container body 222.

As described above, even in the case of the container 22 according to the present embodiment, dew condensation is unlikely to occur in the first container main body 221 and the second container main body 222.
