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.

In view of the above circumstances, the present invention provides a means for preventing the water generated by the dew condensation from adversely affecting the contents of the container even if dew condensation occurs in the container provided with the flying object.

[Embodiment]
FIG. 1 is a diagram showing an overall configuration of a flying object 1 according to an 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 a hollow box body for accommodating a crew member H1 and the like inside, an air 122 housed in the container body 121, and a part of the container body 121 which is housed in the container body 121. The dew condensation promoting member 123, which is a member that causes dew condensation earlier than the inner surface of the container body 121 when the water vapor inside the 121 condenses, and the water collecting tray 124 that collects the water generated by the dew condensation in the dew condensation promoting member 123. A guide pipe 125, which is a tube for guiding the water collected by the water collecting tray 124 to the water collecting container 126, and a water collecting container 126 for accommodating the water sent from the water collecting tray 124 through the guide pipe 125. Be prepared.

The projectile 1 can fly to a high altitude space such as tens of thousands of meters from the ground. Therefore, the container body 121 has an airtight structure so that the air pressure inside is maintained while the projectile 1 is flying and the air 122 contained therein does not unintentionally leak to the outside. .. The container body 121 is provided with a hatch or the like for the crew member H1 to enter and exit before the flight body 1 flies, but the illustration thereof is omitted in FIG.

The container body 121 is made of, for example, fiber reinforced plastic. The material of the container body 121 is preferably lightweight as long as the required strength can be secured, but the material is not limited to fiber reinforced plastics, for example, light metals such as aluminum, plastics that are not fiber reinforced plastics, and combinations thereof. And so on.

The air 122 is a gas containing sufficient oxygen so that the crew member H1 can breathe. Further, by filling the container body 121 with an appropriate amount of air 122, the pressure inside the container body 121 is kept at an atmospheric pressure. Further, the air 122 contains water vapor.

The dew condensation promoting member 123 has a higher thermal conductivity than the portion constituting the inner surface of the container body 121. Further, a part of the dew condensation promoting member 123 is housed inside the container body 121, and the other part of the dew condensation promoting member 123 is arranged outside the container body 121. Therefore, when the water vapor inside the container body 121 condenses, it cools faster than the inner surface of the container body 121, and as described above, it plays a role of causing dew condensation earlier than the inner surface of the container body 121. The dew condensation promoting member 123 is a light metal such as aluminum, but in this case, it may be made of a material other than the light metal as long as it has a higher thermal conductivity than the fiber reinforced plastic constituting the container body 121.

The water collecting tray 124 is arranged below the dew condensation promoting member 123 (the portion housed inside the container body 121), and accompanies the dew condensation on the dew condensation promoting member 123 (the part housed inside the container body 121). When the generated water becomes water droplets and falls, the water droplets are received and collected. The water collecting dish 124 is perforated, and the water falling through the hole falls through the guide pipe 125 into the water collecting container 126. The water collection container 126 is a container for accommodating water falling from the water collecting tray 124. The water contained in the water collection container 126 is usually discarded after the projectile 1 returns to the ground, but is used, for example, when a water shortage occurs in the container body 121 due to some accident.

According to the container 12 described above, when dew condensation occurs in the container main body 121, the dew condensation occurs in the dew condensation promoting member 123, and the generation of dew condensation on the inner surface of the container main body 121 is suppressed. Then, the water generated in the dew condensation promoting member 123 is stored in the water collecting container 126 and does not infiltrate the surrounding contents. As a result, there is no inconvenience that the water generated by dew condensation adversely affects the contents.

[Modification example]
The flying object 1 according to the above-described embodiment may be variously modified within the scope of the technical idea of the present invention. An example of these variations is shown below. In addition, two or more of the following modified examples may be combined as appropriate.

(1) In the flying object 1 according to the above-described embodiment, the water collecting container 126 for accommodating the water generated by the dew condensation in the dew condensation promoting member 123 is arranged inside the container main body 121. The arrangement position of the water collecting container 126 is not limited to the inside of the container body 121.

FIG. 3 is a diagram showing the configuration of the container 12 according to this modified example. The container 12 in FIG. 3 includes a ballast tank 127 arranged outside the container body 121 in place of the water collecting container 126. The ballast tank 127 is a tank for accommodating ballast water for adjusting the altitude of the projectile 1, and has a valve 1271 for opening and closing an opening (drainage port) for draining the ballast water to the outside of the ballast tank 127. ..

The valve 1271 opens and closes according to a control signal transmitted wirelessly or by wire from, for example, a communication terminal device (not shown in FIG. 3) operated by the crew member H1. Alternatively, the container 12 opens and closes a valve that operates, for example, the valve 1271 opens while the operating rope is pulled by the crew member H1, and the valve 1271 closes while the operating rope is not pulled by the crew member H1. A mechanism (not shown in FIG. 3) may be provided. In this case, the water collecting tray 124, the guide pipe 125, the valve 1271, and the valve opening / closing mechanism constitute an example of a drainage mechanism for discharging the water generated by the dew condensation in the dew condensation promoting member 123 to the outside of the container body 121. ..

In the container 12 of FIG. 3, the water generated by the dew condensation in the dew condensation promoting member 123 falls on the water collecting dish 124 and is collected, and falls on the ballast tank 127 through the guide pipe 125 and becomes a part of the ballast water. After that, when the valve 1271 is opened in response to the operation of the crew member H1, the ballast is discharged to the outside of the ballast tank 127 (that is, the outside of the container 12) as a part of the ballast water.

In the container 12 of FIG. 3, the ballast tank 127 also serves as the water collecting container 126. Alternatively, the water collecting container 126, which is not the ballast tank 127, may be arranged outside the container body 121. Further, the water generated by the dew condensation in the dew condensation promoting member 123 may be guided to the outside of the container main body 121 by the guide pipe 125 and drained without the water collecting container 126. In this case, the container 12 is configured to include a valve that restricts the flow of water in the guide pipe 125, and an opening / closing mechanism that opens and closes the valve in response to an operation of the crew member H1 or the like. The water collecting tray 124, the guide pipe 125, the valve, and the opening / closing mechanism of the valve constitute an example of a drainage mechanism for discharging the water generated by dew condensation in the dew condensation promoting member 123 to the outside of the container body 121.

(2) The water generated by the dew condensation in the dew condensation promoting member 123 may be absorbed by the water absorbing material instead of being stored in the water collecting container 126 or drained to the outside of the container main body 121.

FIG. 4 is a diagram showing the configuration of the container 12 according to this modified example. The container 12 in FIG. 4 does not include a guide pipe 125 and a water collecting container 126. Further, the water collecting tray 124 provided in the container 12 of FIG. 4 does not have a drainage port and accommodates the water absorbing material 128. The water-absorbing material 128 is a material that absorbs water and becomes a gel-like object, or a material that absorbs water and solidifies. As the water-absorbing material 128, for example, a water-absorbing polymer or the like can be used, but the water-absorbing material 128 is not limited to this.

According to the container 12 according to this modification, the water generated by the dew condensation in the dew condensation promoting member 123 is absorbed by the water absorbing material 128 and does not go toward other contents in the container main body 121, so that the contents are adversely affected by water. You will not receive it.

(3) In the container 12 according to the above-described embodiment, when dew condensation occurs inside the container main body 121, it is a member different from the container main body 121 so that dew condensation does not occur on the inner side surface of the container main body 121. A configuration is adopted in which a dew condensation promoting member 123 is provided and dew condensation is generated in the dew condensation promoting member 123.

Instead, the wall surface of the container body 121 has a low thermal conductivity region in which the thermal conductivity in the inner and outer directions of the container body 121 is relatively low, and a high thermal conductivity region in which the thermal conductivity in the inner and outer directions of the container body 121 is relatively high. It is divided into a rate region, and the high thermal conductivity region plays the same role as the dew condensation promoting member 123 by causing dew condensation earlier than the low thermal conductivity region when the water vapor inside the container body 121 condenses. It may be configured.

FIG. 5 is a diagram showing the configuration of the container 12 according to this modified example. The container 12 in FIG. 5 does not include the dew condensation promoting member 123. The container body 121 included in the container 12 of FIG. 5 has a high thermal conductivity region 121A (a region indicated by an arrow C in FIG. 5) formed to have a thinner wall surface than other portions, and a high thermal conductivity region. It is divided into a low thermal conductivity region 121B formed with a wall thickness thicker than that of 121A. Since the wall surface of the high thermal conductivity region 121A is thinner than that of the low thermal conductivity region 121B, the thermal conductivity in the inner and outer directions of the container body 121 is higher than that of the low thermal conductivity region 121B. Therefore, the high thermal conductivity region 121A is cooled faster than the low thermal conductivity region 121B under the condition that the outside of the container main body 121 is colder than the inside. As a result, when dew condensation occurs inside the container body 121, dew condensation occurs in the high thermal conductivity region 121A earlier than the low thermal conductivity region 121B.

In FIG. 5, the water generated by the dew condensation in the high thermal conductivity region 121A is absorbed by the water absorbing material 128 housed in the water collecting tray 124, but instead of this, the dew condensation in the high thermal conductivity region 121A causes the water to be absorbed. The generated water may be contained in the water collecting container 126 or the ballast tank 127, or may be drained to the outside of the container main body 121 through the ballast tank 127 or not through the ballast tank 127.

FIG. 6 is a diagram showing the configuration of the container 12 according to another modification. The container body 121 of the container 12 of FIG. 6 includes an outer wall 1211, an inner side wall 1212, and a heat insulating material 1213 housed between them. The heat insulating material 1213 is, for example, a member having a lower thermal conductivity in the inner and outer directions of the container body 121 than the outer wall 1211 and the inner side wall 1212.

In the container 12 of FIG. 6, in the high thermal conductivity region 121A indicated by the arrow C, the heat insulating material 1213 is not accommodated between the outer wall surface 1211 and the inner side wall surface 1212. Therefore, the high thermal conductivity region 121A has a higher thermal conductivity than the low thermal conductivity region 121B, which is a region other than the high thermal conductivity region 121A, and has a high thermal conductivity under the condition that the outside of the container body 121 is colder than the inside. The region 121A is cooled faster than the low thermal conductivity region 121B. As a result, when dew condensation occurs inside the container body 121, dew condensation occurs in the high thermal conductivity region 121A earlier than the low thermal conductivity region 121B.

In the container 12 of FIG. 6, the high heat conductivity region 121A does not have the heat insulating material 1213, but instead, the thickness of the heat insulating material 1213 possessed by the high heat conductivity region 121A (thickness in the inner and outer directions of the container body 121). However, a configuration thinner than the thickness of the heat insulating material 1213 possessed by the low thermal conductivity region 121B may be adopted.

FIG. 7 is a diagram showing the configuration of the container 12 according to still another modification. In the container body 121 of the container 12 of FIG. 7, in the high thermal conductivity region 121A indicated by the arrow C, the dew condensation promoting member 123 exposed inside the container body 121 on the inner side surface forms a part of the container body 121. .. In FIG. 7, only a part of the container body 121 is occupied by the dew condensation promoting member 123 in the high thermal conductivity region 121A, but the entire container body 121 is occupied by the dew condensation promoting member 123 in the high thermal conductivity region 121A. It may be.

(4) In the above-described embodiment, the container body 121 is a cabin that accommodates a person, but the container body 121 does not have to be a person. FIG. 8 is a diagram illustrating a case where the container main body 121 accommodates the photographing apparatus H2.

In this modification, an opening is provided in the portion of the wall surface of the container main body 121 in the photographing region (angle of view) of the photographing apparatus H2, and the light transmitting plate 1214 is installed so as to close the opening. ing. The photographing device H2 captures an image by detecting the light transmitted from the outside through the light transmitting plate 1214.

Also in the example of FIG. 8, similarly to the container 12 according to the above-described embodiment, the dew condensation promoting member 123 has a higher thermal conductivity than the portion constituting the inner surface of the container body 121 (including the light transmitting plate 1214). When the water vapor inside the container body 121 condenses, it causes dew condensation earlier than the inner surface of the container body 121. As a result, for example, the light transmitting plate 1214 does not have water droplets due to dew condensation, and when the photographing apparatus H2 photographs the outside through the light transmitting plate 1214, the water droplets do not focus or the water droplets appear on the captured image. There is no inconvenience such as crowding.

(5) It is not necessary to provide a mechanism for accommodating water generated by dew condensation in the dew condensation promoting member 123. For example, the container 12 does not have to include the water collecting tray 124, the guide pipe 125, and the water collecting container 126 provided in the container 12 according to the above-described embodiment. In that case, the water generated by the dew condensation in the dew condensation promoting member 123 falls on the floor of the container body 121 and flows on the floor, but if there is no container such as a device affected by the inundation around it, it is particularly special. No problem arises.

(6) In the above-described embodiment, the flying object is a gas balloon, but the type of the flying object is not limited to the gas balloon, and may be another type of flying object such as a hot air balloon or an airship.
