Description

Technical Field

[0001] The invention relates to the field of high-altitude balloon inflation, and in particular to a high-altitude balloon inflation tube and an inflation method. Background Art

[0002] High-altitude balloons are made of materials with a thickness of microns and a maximum volume of one million cubic meters. They play a significant role in high-altitude scientific research. High-altitude balloons are inflated through an inflation tube connected to the upper part of the sphere. The inflation tube and the sphere are directly welded together. In order to reduce stress concentration at the connection, the balloon inflation tube is usually made of thin film material. The inflation process usually takes tens of minutes to several hours. During the inflation process, the sphere will rotate and sway due to changes in wind speed and wind direction. The inflation operator needs to make real-time position adjustments according to the movement of the sphere. However, when a gust of wind causes the movement of the sphere to change rapidly, the operator may not make timely adjustments, resulting in relative twisting of the inflation tube, blocking the helium filling channel, and the inflation tube ruptures due to instantaneous pressure increase. If the inflation tube ruptures near the sphere, if there is no aerial work vehicle at the test site, the test can only be declared a failure, causing irreversible losses. Even if the inflation tube is repaired by an aerial work vehicle, a lot of precious inflation time window will be wasted, and there is a risk of subsequent wind speed increase. At the same time, the temporary repair quality of the inflation tube also poses a hidden danger to the flight. Summary of the invention

[0027] Combine the following Figure 1-Figure 7 The high altitude balloon inflation tube of the present invention is described.

[0028] The present invention provides a high-altitude balloon inflation tube, comprising a tube body 2 and a protective member 4. The side wall of the tube body 2 is provided with a protective hole 21, and the protective member 4 comprises a substrate 41 and a connecting ring 42, one side of the connecting ring 42 is fixedly connected to the substrate 41. The other side of the connecting ring 42 is provided with an adhesive layer 43, and the adhesive layer 43 is bonded to the side wall of the tube body 2 so that the substrate 41 seals the protective hole 21, and the substrate 41 ruptures before the side wall of the tube body 2 under the same air pressure.

[0029] Specifically, Figure 1 , Figure 3As shown, a protective member 4 is provided on the tube body 2, and the end of the tube body 2 is connected to the sphere 1 of the high-altitude balloon, and helium is introduced into the sphere 1 through the tube body 2. The protective member 4 includes a substrate 41 and a connecting ring 42, and is bonded to the side wall of the tube body 2 through an adhesive layer 43 so that the substrate 41 seals the protective hole 21. The material of the substrate 41 is set so that the substrate 41 breaks before the side wall of the tube body 2 under the same air pressure. When the inflation tube of the high-altitude balloon is twisted, the helium filling passage is blocked, and the pressure of the inflation tube increases, the substrate 41 on the protective member 4 will break before the side wall of the tube body 2, so that the rupture position can be controlled.

[0030] In an alternative embodiment, if Figure 3 As shown, the connecting ring 42 is arranged on the end face of the substrate 41, and the connecting ring 42 is arranged in a rounded rectangular structure, and the substrate 41 is a thin film material. The connecting ring 42 can be connected to the end face of the substrate 41 by means of or gluing, and the substrate 41 covers the through hole of the connecting ring 42. The end face of the connecting ring 42 away from the substrate 41 is coated with an adhesive to form an adhesive layer 43, and the adhesive layer 43 is bonded around the protective hole 21, so that the adhesive layer 43 is bonded to the side wall of the tube body 2 so that the substrate 41 seals the protective hole 21.

[0031] In another alternative embodiment, if Figure 4 As shown, the substrate 41 is arranged inside the through hole of the connecting ring 42, and the substrate 41 and the through hole of the connecting ring 42 are fused or bonded into an integral structure, forming a seal between the substrate 41 and the through hole of the connecting ring 42, and the bonding layer 43 is arranged on the end surface of the connecting ring 42. When the connector is fixedly connected to the pipe body 2, the bonding layer 43 is distributed around the protective hole 21 and adheres to the outer wall of the pipe body 2, so that the bonding layer 43 is bonded to the side wall of the pipe body 2 so that the substrate 41 seals the protective hole 21.

[0032] The present invention provides a high-altitude balloon inflation tube. By setting a protection hole 21 on the tube body 2 and connecting a protection member 4 to the protection hole 21, the position of the protection hole 21 can be adjusted and the protection member 4 can be connected to the corresponding protection hole 21 to connect the protection member 4, so that the rupture position can be adjusted as needed, making it more convenient to repair the rupture. It is only necessary to replace the protection member 4 where the base material 41 is ruptured, which further makes the maintenance more convenient.

[0033] Furthermore, when the protective member 4 is not connected to the tube body 2 , a release film 44 is detachably connected to the adhesive layer 43 .

[0034] Specifically, Figure 5 As shown, when the protective member 4 is not connected to the tube body 2, a release film 44 is covered on the adhesive layer 43. When the connector is bonded and fixed to the tube body 2, the release film 44 is peeled off from the adhesive layer 43, which facilitates the connection of the protective member 4.

[0035] In an optional embodiment, the materials of the substrate 41 and the tube body 2 are different, and the tensile strength of the substrate 41 is smaller than that of the tube body 2, so that the substrate 41 ruptures before the side wall of the tube body 2 under the same gas pressure.

[0036] In another optional embodiment, the substrate 41 is made of the same material as the tube body 2, and the thickness of the substrate 41 is less than the thickness of the side wall of the tube body 2. By setting the thickness of the substrate 41 to be less than the thickness of the tube body 2, the substrate 41 is broken before the side wall of the tube body 2 under the same gas pressure. Further, the thickness of the substrate 41 is 1 / 3 to 1 / 2 of the thickness of the side wall of the tube body 2. It is prevented that the substrate 41 is too thin to affect the normal filling of helium.

[0037] In an alternative embodiment, if Figure 6 As shown, a plurality of protection holes 21 are provided, and the protection member 4 is provided in a one-to-one correspondence with the protection holes 21. According to the inflation rate requirement, the number of the protection holes 21 and the protection member 4 on the tube body 2 can be adjusted. When the inflation rate is low, only one protection hole 21 and the protection member 4 can be provided. When the inflation rate is high, a plurality of protection holes 21 and the protection member 4 can be installed, and the protection member 4 is provided in a one-to-one correspondence with the protection holes 21 to improve the pressure relief capacity of the protection member 4.

[0038] In an alternative embodiment, if Figure 2 , Figure 6 As shown, the tube body 2 is configured as a cylindrical structure composed of a membrane, and the material is nylon or polyethylene or other materials. Two tubes are arranged on both sides of the sphere 1 to back up each other.

[0039] The present invention also discloses a method for inflating a high-altitude balloon. The high-altitude balloon comprises a sphere 1 and a tube 2. The tube 2 is connected to the sphere 1. The inflation method comprises the following steps: S1, a protection hole 21 is opened on the side wall of the tube body 2, the protection member 4 is connected to the protection hole 21, and the adhesive layer 43 is adhered to the side wall of the tube body 2 so that the substrate 41 seals the protection hole 21; S2, connecting the end of the tube body 2 away from the sphere 1 to the inflation device 3, and the inflation device 3 fills helium into the sphere 1 through the tube body 2; S3, after the inflation is completed, the tube body 2 is cut off, the tube body 2 connected with the protective member 4 is cut off, and the cut tube body 2 is sealed.

[0040] Specifically, when in use, the tube body 2 on the high-altitude balloon is used together with the protective component 4 to assemble a high-altitude balloon inflation tube in any of the above-mentioned embodiments. A protective hole 21 is opened on the side wall of the tube body 2, and the protective component 4 is connected to the protective hole 21. The adhesive layer 43 is bonded to the side wall of the tube body 2 so that the substrate 41 seals the protective hole 21. One end of the tube body 2 is connected to the air outlet of the inflation device 3. The inflation operator manually clamps the tube body 2 on the air outlet of the inflation device 3 and opens the valve on the inflation device 3 to inflate. After the inflation is completed, the tube body 2 connected to the protective component 4 is cut off, so that the tube body 2 connected to the high-altitude balloon after the inflation is completed does not contain the substrate 41 with low strength, so as to ensure the reliability of the high-altitude ball when in use. The specific method of opening the protective hole 21: The method of opening the protective hole 21 on the tube body 2 is to place the tube body 2 on a pad, and place a template 5 on it, such as Figure 7 As shown, a carving knife is used to cut out the protection holes 21 along the mold holes 51 on the template 5. At this time, there are two openings. Alternatively, the pad can be placed in the tube body 2. At this time, there is only one opening on one side.

[0041] Furthermore, before step S1, the following steps are also included: S01, calculating the target length of the tube body 2 according to the mass of helium filled; S02, cutting the tube body 2 to a target length.

[0042] Furthermore, the target length is calculated as: Wherein, L is the target length, is the mass of helium to be filled, is the molar mass of helium, is the gas constant, is the ambient temperature, is the atmospheric pressure, and k is the proportional coefficient, which takes a value of 1.8~2.

[0043] According to the calculated target length of the tube body 2, the excess tube body 2 at the lower end is cut off to keep the tube body 2 of the required length.

[0044] Furthermore, the distance between the protection hole 21 and the cutting position of the tube body 2 is not less than 1m. Specifically, the spacing between the protection hole 21 and the cutting position facilitates the connection between the port of the tube body 2 and the inflation device, and avoids the air outlet of the inflation device being directly opposite to the protection member. By adjusting the spacing between the protection hole 21 and the port of the tube body 2, the height of the protection member 4 can be adjusted when the sphere 1 floats, which facilitates the observation of whether the protection member 4 is broken and the replacement of the protection member 4. The distance between the protection hole 21 and the cutting position of the tube body 2 can be 1 meter, 1.5 meters or 2 meters, and other suitable spacings can also be selected according to the habits of the operator.

[0045] Furthermore, step S2 further includes: S21, when the base material 41 is broken, the inflation device 3 is turned off and the inflation into the tube body 2 is stopped; S22 , replacing the protective member 4 with the broken substrate 41 on the tube body 2 , turning on the inflation device 3 , and continuing to inflate helium into the sphere 1 through the tube body 2 .

[0046] When the high-altitude balloon inflation tube twists, the helium filling passage is blocked, the inflation tube pressure increases, and the protective structure film ruptures under high pressure. The inflation operator closes the valve of the inflation device 3; replaces the protective member 4 on the balloon inflation tube, and continues to inflate.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
