Container for flying object

Abstract

The present invention provides a container that is less likely to produce condensation than containers of flying objects in the prior art. The container (12) is a container for a flying object such as a gas balloon, and rises as the flying object rises. A portion of the wall of the container is composed of a plate (121), a plate (122), and a plate (123) that are separated from each other. The plate (121) has one or more holes (H1) of a size that allows gas to enter and exit between the two spaces without producing convection of gas in a manner that eliminates the pressure difference between the space (S1) and the space (S2) sandwiching the plate (121). As the flying object rises, the temperature (T1 to T4) of the space (S1 to S4) produces a relationship of T1 < T2 < T3 < T4. That is, the temperature gradient inside and outside the container becomes gentle, and condensation is less likely to occur on the plates (121), the plates (122), and the plates (123). The plate body (121) has a hole (H1), which plays a role in buffering the force exerted on the plate body (122) due to the pressure difference between the inside and outside of the container.

Description

Technical Field

[0001] The present invention relates to a container for flying objects such as balloons and airships. Background Art

[0002] When a flying object such as a balloon or airship rises, the temperature around the flying object usually decreases. Therefore, when the flying object has an airtight container, the temperature of the wall of the container becomes lower than the temperature of the air inside the container due to the rising of the flying object, and the air in contact with the wall is cooled, so that the water vapor contained in the air turns into water, and sometimes condensation occurs, which adheres to the inside of the wall as dew.

[0003] When light is transmitted through the wall of a container of a flying object, if condensation occurs on the wall, a person in the container cannot clearly visually confirm the scene outside the container, and a photographic device in the container cannot clearly capture the scene outside the container.

[0004] Furthermore, if condensation occurs on the wall surface of a container of a flying object, surrounding objects may be damaged by water ingress.

[0005] As a patent document that discloses an invention for reducing the probability of condensation in a container of a flying object, there is Patent Document 1 related to the invention of the inventor of the present application. Patent Document 1 discloses a container of a flying object, in which at least a part of a wall portion is provided with a double structure, and one or more holes of a size that does not generate convection of the gas are provided in any one of the double-structured walls to allow gas to enter and exit.

[0006] Patent Document 1: Japanese Patent Application Publication No. 2022-51566

[0007] When the container disclosed in Patent Document 1 is used, it may not be possible to sufficiently prevent condensation from occurring in the container depending on conditions related to the temperature and humidity on the ground. Summary of the invention

[0008] In view of the above circumstances, the present invention provides a means for making it difficult for condensation to occur in a container of a flying object, as compared with the invention described in Patent Document 1.

[0009] The first embodiment of the present invention provides a container, which is a container possessed by a flying body, wherein at least a portion of the container is composed of three or more plates separated from each other, at least one of the three or more plates does not have a hole and keeps the space for storing stored items in the container airtight, and at least one of the three or more plates has one or more holes of a size that allows gas to flow in and out between two spaces sandwiching the plate in a manner that eliminates the pressure difference generated between the two spaces but does not generate gas convection between the two spaces.

[0010] In the container of the first embodiment, the following structure can also be adopted as the second embodiment: two or more of the three or more plates have one or more holes of a size that can eliminate the pressure difference generated between the two spaces sandwiched by the plates, thereby allowing gas to enter and exit the two spaces but not generating gas convection between the two spaces.

[0011] In the container of the second embodiment, the following structure can also be adopted as the third embodiment: regarding at least two of the three or more plates having holes, at least two of the two or more plates have holes that are different in size and number.

[0012] According to the present invention, compared with a container included in a conventional flying object, condensation is less likely to occur in the container. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 1 1 is a diagram showing the overall structure of a flying object 1 according to an embodiment of the present invention. The flying object 1 comprises: a balloon 11 containing a gas lighter than air such as helium; a container 12 suspended from the balloon 11 for flight; and a plurality of slings 13 as ropes provided for suspending the container 12 from the balloon 11, one end of the sling 13 being connected to the balloon 11 and the other end being connected to the container 12.

[0025] Figure 2 1 is a cross-sectional view showing the structure of the wall body of the container 12. The container 12 stores the storage object in the space formed inside. In the present application, the storage object includes at least one of an object (including an animal) or a person. Figure 2 In FIG. 1 , a passenger C1 is shown as an example of storage items.

[0026] The portion of the wall of the container 12 that is surrounded by the dotted line is composed of three plates 121 , 122 , and 123 that are separated from each other.

[0027] The plates 121 , 122 , and 123 form a space S2 , a space S3 , and a space S4 inside the container 12 .

[0028] The plate 121 is sandwiched between the space S1 outside the container 12 and the space S2 among the three spaces formed inside the container 12, and separates the two spaces. The plate 122 is sandwiched between the space S2 and the space S3 among the three spaces formed inside the container 12, and separates the two spaces. The plate 123 is sandwiched between the space S3 and the space S4 among the three spaces formed inside the container 12, and separates the two spaces.

[0029] Hereinafter, the pressures in the spaces S1 to S4 are as follows.

[0030] Pressure in space S1: Pressure P1

[0031] Pressure in space S2: Pressure P2

[0032] Pressure in space S3: Pressure P3

[0033] Pressure in space S4: Pressure P4

[0034] In addition, below, the temperature in the spaces S1 to S4 is as follows.

[0035] Temperature in space S1: Temperature T1

[0036] Temperature in space S2: Temperature T2

[0037] Temperature in space S3: Temperature T3

[0038] Temperature in space S4: Temperature T4

[0039] The plate 122 and the plate 123 of the three plates do not have holes, and the space for storing the stored items in the container 12 is kept airtight.

[0040] The plate 121 of the three plates has one or more holes H1. The size of each hole H1 is such that the pressure difference between the two spaces (i.e., the space S1 and the space S2) sandwiching the plate 121 is eliminated, and gas can flow in and out between the two spaces but no gas convection can be generated between the two spaces.

[0041] When the flying object 1 ascends and the temperature of the space around the container 12 (ie, the temperature T1 ) decreases, the temperatures in the spaces S1 to S4 have the following relationship.

[0042] T1<T2<T3<T4

[0043] That is, in the triple-structured portion of the wall of the container 12, the temperature rises stepwise from the outside to the inside of the container 12. That is, in the triple-structured portion of the wall of the container 12, the temperature gradient between the inside and outside of the container 12 becomes gentler than in the portion without the triple-structured portion. Therefore, condensation is less likely to occur on the plate bodies 121, 122, and 123.

[0044] Therefore, when the plates 121, 122, and 123 transmit light, when the person in the space S4 observes the scene outside the container 12 through these plates, it is not easy to cause an unfavorable situation that the scene cannot be seen well due to condensation. In addition, when the camera device in the space S4 takes a picture of the scene outside the container 12 through these plates, it is not easy to cause an unfavorable situation that the image of the scene cannot be clearly taken due to condensation. In addition, it is not easy to cause an unfavorable situation that the storage items in the space S4 are soaked in water due to condensation generated on the plates 123.

[0045] When the flying object 1 ascends and the pressure (ie, pressure P1) of the space around the container 12 (ie, space S1) decreases, the pressures in the spaces S1 to S4 have the following relationship.

[0046] P1≤P2<<P3<P4

[0047] Here, "≤" means that the right side is larger than the left side, but the difference between the left and right sides tends to disappear (gradually decreases) over time. In addition, "<<" means that the right side is significantly larger than the left side (the difference between the left and right sides is larger than "<").

[0048] As described above, the pressure P2 of space S2 is greatly different from the pressure P3 of space S3. Therefore, the plate 122 sandwiched between space S2 and space S3 is subjected to a large force from the inside to the outside due to the pressure difference generated between the two spaces. In order to overcome this force, the plate 122 has a higher rigidity than the plate 121 and the plate 123.

[0049] However, the difference between the pressure P1 of the space S1 and the pressure P2 of the space S2 tends to be eliminated by the inflow and outflow of the gas through the hole H1, but the flow rate of the gas through the hole H1 is not fast enough to instantly eliminate the pressure difference generated by the ascent of the flying body 1. In other words, it takes time for the difference between the pressure P1 and the pressure P2 to be eliminated gradually.

[0050] Therefore, the plate 121 receives a part of the force from the inside to the outside generated by the pressure difference between the inside and the outside of the container 12 accompanying the rise of the flying body 1. As a result, the force received by the plate 122 is reduced. In this way, the plate 121 having the hole H1 plays a role in buffering the force pressing the plate 122 to the outside, and as a result, the rigidity required for the plate 122 is reduced, and the overall weight of the container 12 can be reduced. In addition, the strain generated in the plate 122 is reduced, and it is less likely to cause distortion in the scene of the outside that is visually confirmed (or photographed) from the inside of the container 12.

[0051] [Modifications]

[0052] The container 12 of the flying body 1 of the above-mentioned embodiment can be variously modified within the scope of the technical concept of the present invention. The following are the modified examples. In addition, two or more of the following modified examples can be appropriately combined.

[0053] (1) In the container 12 of the above embodiment, the plate body 121 has one or more holes. Alternatively, the plate body 122 or the plate body 123 may have a hole similar to the hole H1.

[0054] Figure 3 FIG. 1 is a cross-sectional view of an example of the container 12 of this modified example. Figure 3 In the container 12 shown, the plate body 121 does not have the hole H1 , and the plate body 122 has one or more holes H2 similar to the hole H1 .

[0055] exist Figure 3In the container 12 shown, as the flying object 1 ascends, the relationship between the temperatures in the spaces S1 to S4 is as follows.

[0056] T1<T2<T3<T4

[0057] Therefore, similarly to the case of the container 12 of the above-described embodiment, condensation is unlikely to occur on the plate body 121 , the plate body 122 , and the plate body 123 .

[0058] In addition, Figure 3 In the container 12 shown, as the flying object 1 ascends, the relationship between the pressures in the spaces S1 to S4 is as follows.

[0059] P1<<P2≤P3<P4

[0060] In this case, the maximum force is applied to the plate 121, but the plate 122 plays a role of buffering the force. As a result, the rigidity required for the plate 121 is reduced, and the overall weight of the container 12 can be reduced. In addition, the strain generated in the plate 121 is reduced, and it is less likely to cause distortion in the scene outside the container 12 that is visually confirmed (or photographed) from the inside.

[0061] In this case, the plate 122 also plays a role of buffering the force applied to the plate 123. As a result, the strain generated in the plate 123 is reduced, and the scene outside that is visually confirmed (or photographed) from the inside of the container 12 is less likely to be distorted.

[0062] Figure 4 FIG. 1 is a cross-sectional view of another example of the container 12 of this modified example. Figure 4 In the container 12 shown, the plate body 121 does not have the hole H1 , the plate body 122 does not have the hole H2 , and the plate body 123 has one or more holes H3 similar to the hole H1 .

[0063] exist Figure 4 In the container 12 shown, as the flying object 1 ascends, the relationship between the temperatures in the spaces S1 to S4 is as follows.

[0064] T1<T2<T3<T4

[0065] Therefore, similarly to the case of the container 12 of the above-described embodiment, condensation is unlikely to occur on the plate body 121 , the plate body 122 , and the plate body 123 .

[0066] In addition, Figure 4 In the container 12 shown, as the flying object 1 ascends, the relationship between the pressures in the spaces S1 to S4 is as follows.

[0067] P1<<P2<P3≤P4

[0068] In this case, the plate 123 cannot significantly reduce the force applied to the plate 121, but plays a role in buffering the force applied to the plate 122. As a result, the strain generated in the plate 123 is reduced, and it is less likely to cause distortion in the scene outside that is visually confirmed (or photographed) from the inside of the container 12.

[0069] (2) In the container 12 of the above-mentioned embodiment, only one of the three plates constituting the triple structure portion of the wall of the container 12 (i.e., only the plate 121) has a hole, but two of the three plates may have holes.

[0070] Figure 5 FIG. 1 is a cross-sectional view of an example of the container 12 of this modified example. Figure 5 In the container 12 shown, the plate 121 has a hole H1 , the plate 122 has a hole H2 , and the plate 123 has no hole.

[0071] exist Figure 5 In the container 12 shown, as the flying object 1 ascends, the relationship between the temperatures in the spaces S1 to S4 is as follows.

[0072] T1<T2<T3<T4

[0073] Therefore, similarly to the case of the container 12 of the above-described embodiment, condensation is unlikely to occur on the plate body 121 , the plate body 122 , and the plate body 123 .

[0074] In addition, Figure 5 In the container 12 shown, as the flying object 1 ascends, the relationship between the pressures in the spaces S1 to S4 is as follows.

[0075] P1≤P2≤P3<<P4

[0076] In this case, the maximum force is applied to the plate 123, but the plate 121 and the plate 122 play a role of buffering the force. As a result, the rigidity required for the plate 123 is reduced, and the overall weight of the container 12 can be reduced. In addition, the strain generated in the plate 123 is reduced, and it is less likely to cause distortion in the scene outside that is visually confirmed (or photographed) from the inside of the container 12.

[0077] Figure 6 FIG. 1 is a cross-sectional view of another example of the container 12 of this modified example. Figure 6 In the container 12 shown, the plate 121 has a hole H1 , the plate 123 has a hole H3 , and the plate 122 has no hole.

[0078] exist Figure 6 In the container 12 shown, as the flying object 1 ascends, the relationship between the temperatures in the spaces S1 to S4 is as follows.

[0079] T1<T2<T3<T4

[0080] Therefore, similarly to the case of the container 12 of the above-described embodiment, condensation is unlikely to occur on the plate body 121 , the plate body 122 , and the plate body 123 .

[0081] In addition, Figure 6 In the container 12 shown, as the flying object 1 ascends, the relationship between the pressures in the spaces S1 to S4 is as follows.

[0082] P1≤P2<<P3≤P4

[0083] In this case, the greatest force is applied to the plate 122, but the plate 121 and the plate 123 play a role in buffering the force. As a result, the rigidity required for the plate 122 is reduced, and the overall weight of the container 12 can be reduced. In addition, the strain generated in the plate 122 is reduced, and it is less likely to cause distortion in the scene outside that is visually confirmed (or photographed) from the inside of the container 12.

[0084] Figure 7 FIG. 1 is a cross-sectional view of another example of the container 12 of this modified example. Figure 7 In the container 12 shown, the plate 122 has a hole H2, the plate 123 has a hole H3, and the plate 121 has no hole.

[0085] exist Figure 7 In the container 12 shown, as the flying object 1 ascends, the relationship between the temperatures in the spaces S1 to S4 is as follows.

[0086] T1<T2<T3<T4

[0087] Therefore, similarly to the case of the container 12 of the above-described embodiment, condensation is unlikely to occur on the plate body 121 , the plate body 122 , and the plate body 123 .

[0088] In addition, Figure 7 In the container 12 shown, as the flying object 1 ascends, the relationship between the pressures in the spaces S1 to S4 is as follows.

[0089] P1<<P2≤P3≤P4

[0090] In this case, the greatest force is applied to the plate 121, but the plate 122 and the plate 123 play a role in buffering the force. As a result, the rigidity required for the plate 121 is reduced, and the overall weight of the container 12 can be reduced. In addition, the strain generated in the plate 121 is reduced, and it is less likely to cause distortion in the scene outside that is visually confirmed (or photographed) from the inside of the container 12.

[0091] However, in the container 12 of this modified example, the two plates having holes may have at least one of the number and size of holes that are different from each other. Figure 5 In the container 12 shown, at least one of the number and size of the holes H1 of the plate 121 and the holes H2 of the plate 122 can be adjusted to reduce the rigidity required of the plate 121 and the plate 122 and the strain generated in these plates. Through such adjustment, in most cases, at least one of the number and size of the holes H1 and the holes H2 is different.

[0092] (3) In the above-mentioned embodiment, one region of the wall of the container 12 has a triple structure. Alternatively, two or more regions of the wall of the container 12 may have a triple structure.

[0093] Figure 8 FIG. 1 is a cross-sectional view of an example of the container 12 of this modified example. Figure 8 In the container 12 shown, two regions surrounded by dotted lines each have a triple structure.

[0094] Alternatively, the entire wall of the container 12 may have a triple structure.

[0095] Fig. 9 FIG. 1 is a cross-sectional view of an example of the container 12 of this modified example. Fig. 9 In the container 12 shown, the entire wall of the container 12 has a triple structure.

[0096] (4) In the above-mentioned embodiment, at least a portion of the wall of the container 12 is composed of a triple structure, that is, three plates separated from each other. Alternatively, at least a portion of the wall of the container 12 may be composed of four or more plates separated from each other. In this case, it is sufficient that at least one of the four or more plates of the container 12 does not have a hole, and at least one of the four or more plates of the container 12 has a hole. In addition, two or more plates (for example, three plates) of the four or more plates of the container 12 may have a hole.

[0097] (5) In the above-mentioned embodiment, the flying object is a gas balloon, but the type of the flying object is not limited to a gas balloon, and may be other types of flying objects such as a hot air balloon and an airship.
