Description

Technical Field

[0001] This application relates to the field of high-altitude aircraft launch technology, and in particular to high-altitude balloon inflation devices and launch containers. Background Technology

[0002] High-altitude balloons, as an important platform for exploring near-space, have seen rapid development both domestically and internationally in recent years. There are two main methods for filling high-altitude balloons with helium: one uses a thin-film hose, which is manually tightened after inflation to create a seal. This method is convenient and reliable, but the balloon carries a long inflation hose, posing a risk of interference. The other method uses a rigid high-pressure hose, requiring manual disconnection of the filling connector and sealing of the filling port after inflation. This method offers good sealing, but the filling port gradually rises as the balloon expands, requiring specialized personnel to perform the sealing operation from an aerial work vehicle, posing a safety hazard. Furthermore, both methods require manual sealing, resulting in a low degree of automation. Summary of the Invention

[0003] This application aims to solve at least one of the technical problems existing in the related art. To this end, this application proposes a high-altitude balloon inflation device that realizes automatic sealing of the high-altitude balloon upon completion of inflation, thereby automatically separating the inflation tube from the high-altitude balloon. This effectively reduces manual operation, lowers safety hazards, improves the automation level of high-altitude balloon inflation, and avoids the risk of interference between the high-altitude balloon and other components, as the high-altitude balloon carries a flexible hose during ascent.

[0004] This application also proposes a high-altitude balloon launch container.

[0005] A high-altitude balloon inflation device according to a first aspect embodiment of this application includes:

[0006] A self-sealing valve is installed on a high-altitude balloon. A cavity is formed inside the self-sealing valve. A connecting channel is provided at the first end of the self-sealing valve, and an air outlet communicating with the cavity is provided at the second end of the self-sealing valve. The air outlet is connected to the high-altitude balloon.

[0007] A flexible switching element is disposed within the cavity;

[0008] An inflatable rigid tube is movable relative to the connecting channel, allowing the resilient switch element to switch between an open state and a closed state. In the open state, the inflatable rigid tube abuts against the resilient switch element and is connected to the cavity. In the closed state, the inflatable rigid tube is disengaged from the resilient switch element, and the cavity is not connected to the inflatable rigid tube or the outside.

[0009] A snap-fit ​​assembly is provided on the inflation rigid tube, and in the open state, the snap-fit ​​assembly snaps into the self-sealing valve.

[0010] According to the embodiments of this application, a high-altitude balloon delivery cabin has a self-sealing valve installed on the high-altitude balloon, with the outlet of the self-sealing valve connected to the high-altitude balloon. An inflation hose is fixedly connected to the ground or ground-based equipment. When the high-altitude balloon needs to be inflated, the inflation hose is moved to the self-sealing valve, causing one end of the hose to engage with the connecting channel and move along the channel. The inflation hose abuts against a resilient switching element, causing the resilient switching element to deform. At this time, the resilient switching element is in the open state, and the inflation hose is connected to the cavity. Helium or other suitable gases can then be delivered into the cavity through the inflation hose. The gas is then delivered into the high-altitude balloon from the outlet of the self-sealing valve, thus realizing the inflation operation of the high-altitude balloon. In the open state, the locking assembly engages with the self-sealing valve. After the balloon is fully inflated, the buoyancy of the balloon causes the self-sealing valve to rise, disengaging the locking assembly from the valve. The inflation hose gradually moves away from the connection channel, meaning it no longer abuts against the elastic switch element. As the elastic switch element returns to its original shape, it isolates the cavity from the outside, preventing the balloon from communicating with the outside world. This achieves automatic sealing of the balloon upon completion of inflation, automatically separating the inflation hose from the balloon. This effectively reduces manual operation, lowers safety hazards, improves the automation level of balloon inflation, and avoids the risk of interference between the balloon and other components, especially when the balloon carries a hose during ascent.

[0011] According to one embodiment of this application, the resilient switch element includes a resilient element and a sealing cap, one end of the resilient element is connected to the self-sealing valve, and the other end of the resilient element is connected to the sealing cap;

[0012] During the process of the elastic switch element switching from the closed state to the open state, the inflatable rigid tube applies an external force to the sealing cover, causing the sealing cover to move away from the connection channel, thereby causing the elastic element to deform.

[0013] During the process of the elastic switch element switching from the open state to the closed state, the external force applied to the sealing cover by the inflatable rigid tube is removed, and the elastic element returns to its original shape, causing the sealing cover to move towards the connecting channel, so that the sealing cover is sealed to either the inner wall surface of the cavity or the inner wall surface of the connecting channel.

[0014] According to one embodiment of this application, the sealing cover is provided with a first sealing element, in the closed state:

[0015] The first sealing element abuts against the inner wall surface of the cavity; or,

[0016] The first seal abuts against the inner wall of the connecting channel.

[0017] According to one embodiment of this application, the resilient switch element includes a limiting rod connected to the self-sealing valve, and a sealing cap located between the limiting rod and the inflation tube, with the limiting rod positioned on the movement path of the sealing cap.

[0018] According to one embodiment of this application, a vent hole is provided on the side wall of the end of the inflatable rigid tube that abuts against the elastic switch element, and in the open state, the vent hole is located in the cavity.

[0019] According to one embodiment of this application, the inflatable rigid tube is provided with a second seal, which abuts against the end face of the first end of the self-sealing valve, or the second seal abuts against the inner wall surface of the connecting channel.

[0020] According to one embodiment of this application, the snap-fit ​​assembly includes a gripper rod installed on the inflation rigid tube, the first end of the self-sealing valve has a tapered structure, and the gripper rod is adapted to snap into the first end of the self-sealing valve.

[0021] According to one embodiment of this application, the snap-fit ​​assembly includes a cutter, a third tether, and at least two gripping rods, each of the at least two gripping rods having a connecting hole. The first end of the third tether passes through the connecting holes of the at least two gripping rods in sequence, and the first end of the third tether is connected to the second end of the third tether. The cutter is located at the third tether and is adapted to cut the third tether.

[0022] According to one embodiment of this application, the high-altitude balloon inflation device includes a helium storage device and an outlet pipe. The outlet pipe is installed at the second end of the self-sealing valve and communicates with the outlet. The outlet pipe is located inside the high-altitude balloon and has multiple outlet holes. The helium storage device is communicated with the inflation rigid pipe. The helium storage device is used to allow gas to flow sequentially through the inflation rigid pipe, the self-sealing valve, and the outlet pipe before entering the high-altitude balloon.

[0023] The high-altitude balloon delivery container according to the second aspect of this application includes the high-altitude balloon inflation device described above.

[0024] The high-altitude balloon launching container according to the embodiments of this application has the same technical effects as the high-altitude balloon inflation device, and will not be described again here.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0049] The following is combined with Figures 1 to 9 This application describes the high-altitude balloon inflation device and the deployment container.

[0050] According to the embodiments of the first aspect of this application, such as Figure 5 and Figure 6 As shown, the high-altitude balloon inflation device includes a self-sealing valve 44, a flexible switching element 45, an inflation rigid tube 46, and a snap-fit ​​assembly 47. The self-sealing valve 44 is installed on the high-altitude balloon 11, and a cavity 441 is formed inside the self-sealing valve 44. The first end of the self-sealing valve 44 is provided with a connecting channel 442, and the second end of the self-sealing valve 44 is provided with an air outlet communicating with the cavity 441. The air outlet is connected to the high-altitude balloon 11. The flexible switching element 45 is disposed inside the cavity 441, and the inflation rigid tube 46 can be positioned relative to the cavity 11. The flexible switch element 45 moves along the connecting channel 442, switching between an open state and a closed state. In the open state, the inflation tube 46 abuts against the flexible switch element 45 and is connected to the cavity 441. In the closed state, the inflation tube 46 is disengaged from the flexible switch element 45, and the cavity 441 is not connected to the inflation tube 46 or the outside. The snap-fit ​​component 47 is located on the inflation tube 46. In the open state, the snap-fit ​​component 47 snaps into the self-sealing valve 44.

[0051] In use, the self-sealing valve 44 is installed on the high-altitude balloon 11, with its outlet connected to the balloon. The inflation hose 46 is fixedly connected to the ground or ground-based equipment. When the high-altitude balloon 11 needs to be inflated, the inflation hose 46 is moved to the self-sealing valve 44, so that one end of the hose engages with the connecting channel 442 and moves along the channel. The hose 46 abuts against the elastic switch element 45, causing the element to deform and open. The hose 46 then connects to the cavity 441, allowing helium or other suitable gases to be delivered into the cavity 441. The gas is then delivered from the outlet of the self-sealing valve 44 into the balloon 11, thus inflating the balloon. In the open state, the snap-fit ​​assembly 47 engages with the self-sealing valve 44. After the high-altitude balloon 11 is fully inflated, its buoyancy causes the self-sealing valve 44 to rise, disengaging the snap-fit ​​assembly 47 from the self-sealing valve 44. The inflation hose 46 gradually moves away from the connecting channel 442, meaning it no longer abuts against the elastic switch element 45. As the elastic switch element 45 recovers its deformation, it isolates the cavity 441 from the outside, preventing the high-altitude balloon 11 from communicating with the outside. This achieves automatic sealing of the high-altitude balloon 11 upon completion of inflation, automatically separating the inflation hose 46 from the balloon 11. This effectively reduces manual operation, lowers safety hazards, improves the automation level of balloon inflation, and avoids the risk of interference between components remaining on the balloon 11 and other parts, as the balloon carries a flexible hose during ascent.

[0052] In the embodiments of this application, the cross-sectional area of ​​the cavity 441 gradually increases along the direction from the connecting channel 442 to the air outlet. The cavity 441 inside the sealing valve is used as the inflation pipeline of the high-altitude balloon 11. Compared with the related technology that directly connects the inflation rigid pipe 46 and the high-altitude balloon 11, this application effectively increases the diameter of the inflation pipeline, so that the self-sealing valve 44 can play the role of inflation and depressurization.

[0053] In one embodiment of this application, such as Figure 6 , Figure 7 and Figure 8 As shown, the elastic switch element 45 includes an elastic element 451 and a sealing cover 452. One end of the elastic element 451 is connected to the self-sealing valve 44, and the other end of the elastic element 451 is connected to the sealing cover 452.

[0054] During the process of switching the elastic switch element 45 from the closed state to the open state, the inflation tube 46 applies an external force to the sealing cover 452, causing the sealing cover 452 to move away from the connection channel 442, and causing the elastic element 451 to deform.

[0055] During the process of the elastic switch element 45 switching from the open state to the closed state, the inflation tube 46 removes the external force applied to the sealing cover 452, and the elastic element 451 returns to its original shape, causing the sealing cover 452 to move towards the connecting channel 442, so that the sealing cover 452 is sealed to either the inner wall surface of the cavity 441 or the inner wall surface of the connecting channel 442.

[0056] Specifically, when the high-altitude balloon 11 needs to be inflated, the inflation tube 46 is inserted into the connecting channel 442, and the inflation tube 46 abuts against the sealing cover 452, causing the sealing cover 452 to move away from the connecting channel 442. The elastic element 451 also deforms accordingly. At this time, the elastic switch element 45 switches from the closed state to the open state, and the inflation tube 46 is connected to the cavity 441. Helium can be delivered to the cavity 441 through the inflation tube 46, and then the helium is delivered to the high-altitude balloon 11 through the outlet of the self-sealing valve 44, thus realizing the inflation operation of the high-altitude balloon 11. After the high-altitude balloon 11 is inflated, the buoyancy of the high-altitude balloon 11 causes the self-sealing valve 44 to break free from the locking assembly 47, so that the self-sealing valve 44 gradually moves away from the inflation tube 46. Then the inflation tube 46 no longer abuts against the sealing cover 452. While the elastic element 451 recovers its deformation, it drives the sealing cover 452 back to its initial position, so that the sealing cover 452 is sealed to the inner wall surface of the cavity 441 or the inner wall surface of the connecting channel 442, thus isolating the cavity 441 from the outside world. This prevents the gas in the high-altitude balloon 11 from being unable to escape through the connecting channel 442, and realizes the automatic sealing operation of the high-altitude balloon 11.

[0057] In one embodiment of this application, such as Figure 6 , Figure 7 and Figure 8 As shown, the sealing cover 452 is provided with a first sealing element 4521, in the closed state:

[0058] The first sealing element 4521 abuts against the inner wall surface of the cavity 441; or,

[0059] The first seal 4521 abuts against the inner wall of the connecting channel 442.

[0060] In use, by providing a first sealing element 4521 on the sealing cover 452, the sealing performance of the self-sealing valve 44 can be effectively improved. Specifically, when the resilient switch element 45 is in the closed state, the sealing cover 452 is located inside the cavity 441, and the first sealing element 4521 on the sealing cover 452 abuts against the inner wall of the cavity 441. The sealing cover 452 and the inner wall of the cavity 441 are sealed together, preventing the cavity 441 from communicating with the outside world, and consequently, preventing the high-altitude balloon 11 from communicating with the outside world. When the resilient switch element 45 is in the closed state, the sealing cover 452 can also be located inside the connecting channel 442. The first sealing element 4521 on the sealing cover 452 is sealed against the inner wall of the connecting channel 442, preventing the cavity 441 from communicating with the outside world through the connecting channel 442, thus achieving a seal on the high-altitude balloon 11.

[0061] Specifically, when the first sealing member 4521 abuts against the inner wall surface of the cavity 441, it is preferable that the first sealing member 4521 abuts against the end face of the connecting channel 442 near the cavity 441.

[0062] In embodiments of this application, the first seal 4521 is, for example, a sealing ring or a sealing sheet. However, it should be understood that the first seal 4521 can also be any other suitable structural component with a sealing function.

[0063] In one embodiment of this application, such as Figure 6 , Figure 7 and Figure 8 As shown, the resilient switch element 45 includes a limiting rod 453, which is connected to the self-sealing valve 44. A sealing cover 452 is located between the limiting rod 453 and the inflation tube 46, with the limiting rod 453 positioned along the movement path of the sealing cover 452. Specifically, during the process of switching the resilient switch element 45 from the closed state to the open state, the inflation tube 46 applies an external force to the sealing cover 452, causing the sealing cover 452 to move away from the connecting channel 442, thus deforming the elastic element 451. The limiting rod 453 limits the movement of the sealing cover 452, ensuring that the inflation tube 46 can only move the sealing cover 452 to the position of the limiting rod 453. This prevents the inflation tube 46 from damaging the resilient switch element 45 or even the high-altitude balloon 11.

[0064] In one embodiment of this application, such as Figure 6 , Figure 7 and Figure 8As shown, a vent hole 461 is provided on the side wall of the end of the inflation tube 46 that abuts against the elastic switch element 45. In the open state, the vent hole 461 is located inside the cavity 441. Specifically, the inflation tube 46 is moved into the cavity 441 along the connecting channel 442, so that the inflation tube 46 abuts against the sealing cover 452, causing the sealing cover 452 to move away from the connecting channel 442. At this time, the elastic switch element 45 is in the open state, and the vent hole 461 on the inflation tube 46 is located inside the cavity 441. Then, helium is supplied into the inflation tube 46, so that the helium can enter the cavity 441 through the vent hole 461, ensuring the gas output speed of the inflation tube 46 and avoiding the situation where the gas output rate of the inflation tube 46 is low due to the obstruction of the sealing cover 452.

[0065] In one embodiment of this application, such as Figure 6 , Figure 7 and Figure 8 As shown, the inflation tube 46 is provided with a second seal 462. The second seal 462 abuts against the end face of the first end of the self-sealing valve 44, or the second seal 462 abuts against the inner wall surface of the connecting channel 442. In use, by providing the second seal 462 on the inflation tube 46, when the elastic switch element 45 is in the open state, the second seal 462 can abut against the end face of the first end of the self-sealing valve 44, ensuring the sealing performance between the inflation tube 46 and the self-sealing valve 44, and preventing helium from leaking between the inflation tube 46 and the self-sealing valve 44; the second seal 462 can also abut against the inner wall surface of the connecting channel 442, thereby ensuring the sealing performance between the inflation tube 46 and the connecting channel 442, so that helium will not leak from the inflation tube 46 and the connecting channel.

[0066] In embodiments of this application, the second seal 462 is, for example, a sealing ring or a sealing sheet. However, it should be understood that the second seal 462 can also be any other suitable structural component with a sealing function.

[0067] In one embodiment of this application, such as Figure 6 , Figure 7 and Figure 8As shown, the snap-fit ​​assembly 47 includes a gripper 471, which is mounted on the inflation tube 46. The first end of the self-sealing valve 44 has a tapered structure, and the gripper 471 is adapted to snap into the first end of the self-sealing valve 44. In use, one end of the gripper 471 is connected to the inflation tube 46, and the other end of the gripper 471 can rotate slightly relative to the inflation tube 46. When it is necessary to inflate the high-altitude balloon 11, the other end of the gripper 471 is first rotated relative to the inflation tube 46, moving the inflation tube 46 along the connecting channel 442 towards the cavity 441, and the other end of the gripper 471 is snapped into the first end of the self-sealing valve 44, so that the inflation tube 46 and the self-sealing valve 44 remain connected. When the high-altitude balloon 11 is fully inflated, the buoyancy of the high-altitude balloon 11 will cause the self-sealing valve 44 to overcome the gripping force of the gripping rod 471, so that the self-sealing valve 44 will disengage from the inflation tube 46, thereby achieving automatic separation between the inflation tube 46 and the high-altitude balloon 11.

[0068] In the embodiments of this application, such as Figure 5 , Figure 6 and Figure 7 As shown, the snap-fit ​​assembly 47 includes a cutter 472, a third tether 473, and at least two gripping rods 471. Each of the at least two gripping rods 471 has a connecting hole. The first end of the third tether 473 passes sequentially through the connecting holes of the at least two gripping rods 471, and the first end of the third tether 473 is connected to the second end of the third tether 473. The cutter 472 is located at the third tether 473 and is adapted to cut the third tether 473. In use, at least two gripping rods 471 are simultaneously snapped into the self-sealing valve 44. Then, the first end of the third tether 473 is sequentially passed through the connecting hole of each gripping rod 471. Next, the first end and the second end of the third tether 473 are connected together, thereby reinforcing the connection between the gripping rods 471 and the self-sealing valve 44 through the third tether 473. Once the high-altitude balloon 11 is fully inflated, the cutter 472 is detonated, cutting the third tether 473 and preventing it from securing the grab bar 471. As a result, under the buoyancy of the high-altitude balloon 11, the high-altitude balloon 11 can lift the self-sealing valve 44 upwards.

[0069] In embodiments of this application, the third tether 473 is, for example, a rubber rope or cord. However, it should be understood that the third tether 473 can also be any other suitable structural component.

[0070] In one embodiment of this application, the snap-fit ​​assembly 47 may further include a snap-fit ​​block disposed on the inflation rigid tube 46 and a snap-fit ​​groove disposed on the self-sealing valve 44, wherein the snap-fit ​​block and the snap-fit ​​groove are snapped together in the open state. However, it should be understood that the snap-fit ​​assembly 47 may also be any other suitable structure.

[0071] In one embodiment of this application, such as Figure 6 , Figure 7 and Figure 8 As shown, the high-altitude balloon inflation device includes a helium storage unit 41 and an outlet pipe 48. The outlet pipe 48 is installed at the second end of the self-sealing valve 44 and communicates with the outlet. The outlet pipe 48 is located inside the high-altitude balloon 11 and has multiple outlet holes. The helium storage unit 41 is connected to the inflation rigid pipe 46. The helium storage unit 41 allows gas to flow sequentially through the inflation rigid pipe 46, the self-sealing valve 44, and the outlet pipe 48 before entering the high-altitude balloon 11. Specifically, before inflating the high-altitude balloon 11, the outlet pipe 48 is inserted into the high-altitude balloon 11. Then, the helium storage unit 41 delivers helium to the self-sealing valve 44 through the outlet pipe 48. The helium then flows along the self-sealing valve 44 and the outlet pipe 48 into the high-altitude balloon 11, thus inflating the high-altitude balloon 11. When the high-altitude balloon 11 is inflated, the exhaust pipe 48 extends into the high-altitude balloon 11. The exhaust pipe 48 can expand the high-altitude balloon 11, preventing the balloon membrane of the high-altitude balloon 11 from sticking together when gas enters the high-altitude balloon 11, thereby effectively reducing the vibration of the balloon membrane caused by gas flow.

[0072] In the embodiments of this application, foam is provided inside the air outlet pipe 48. The foam can further buffer the vibration of the diaphragm when the high-altitude balloon 11 is inflated, and can also effectively reduce noise.

[0073] It should be noted that foam, for example, is EVA foam. However, it should be understood that foam can also be any other suitable type.

[0074] In one embodiment of this application, such as Figure 6 , Figure 7 and Figure 8 As shown, the high-altitude balloon inflation device includes a fixed base 49, an inflation rigid tube 46 fixedly installed on the fixed base 49, and the fixed base 49 fixedly installed on the ground. In use, the fixed base 49 is first fixedly installed on the ground, and then the inflation rigid tube 46 is installed on the fixed base 49, so that the fixed base 49 can limit and fix the inflation rigid tube 46, preventing the inflation rigid tube 46 from rising along with the high-altitude balloon 11.

[0075] In the embodiments of this application, the inflatable rigid tube 46 includes a ball joint and a right-angle elbow connected in sequence, so that the shape of the inflatable rigid tube 46 is L-shaped.

[0076] According to the second aspect of this application, a high-altitude balloon launch container includes the aforementioned high-altitude balloon inflation device. The high-altitude balloon launch container with the inflation device achieves automatic sealing of the high-altitude balloon upon completion of inflation, automatically separating the inflation hose from the high-altitude balloon. This effectively reduces manual operation, lowers safety hazards, improves the automation level of high-altitude balloon inflation, and avoids the risk of interference between components remaining on the high-altitude balloon and other parts, as the high-altitude balloon carries a flexible hose during ascent.

[0077] In the embodiments of this application, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the high-altitude balloon launch container also includes a cabin body 1, a tethering and retraction assembly 2, a first cutting component, an inflation assembly 4, a lifting assembly 5, a gondola 6, and a control assembly. The cabin body 1 houses a high-altitude balloon 11. The tethering and retraction assembly 2 is located inside the cabin body 1 and is connected to the high-altitude balloon 11 via a first tether 21. The first cutting component is located at the first tether 21 and is used to cut the first tether 21. The inflation assembly 4 is located inside the cabin body 1 and is connected to the high-altitude balloon 11. The inflation assembly 4 is adapted to supply gas to the high-altitude balloon 11. The lifting assembly 5 is located inside the cabin body 1 and is connected to the high-altitude balloon 11. The gondola 6 is located at the lifting assembly 5 and is used to lift the gondola 6. The control assembly is connected to the tethering and retraction assembly 2, the first cutting component, the inflation assembly 4, and the lifting assembly 5, respectively.

[0078] According to the embodiments of this application, the high-altitude balloon launch container includes a tethering and deployment assembly 2, a first cutting component, an inflation assembly 4, and a lifting assembly 5, all installed inside the container 1. After the container 1 is sealed, it and its components can be transported together to a designated location, facilitating transportation. Once the container 1 is transported to the designated location, its top plate is opened, and high-altitude balloon launch can begin. No complex on-site installation process is required, enabling rapid deployment of the high-altitude balloon launch container and increasing the launch speed of the high-altitude balloon 11.

[0079] The control component initiates the operation of the inflation component 4, causing it to inflate the high-altitude balloon 11. Upon completion of inflation, the high-altitude balloon 11 is restrained by the first tether 21. The control component then controls the tether release component 2 to continuously release the first tether 21, allowing the high-altitude balloon 11 to rise continuously until it is fully upright. Simultaneously, the control component controls the lifting component 5 to raise the pod 6, ensuring it is above the inner wall of the cabin 1 to prevent collision and damage. The control component then controls the first cutting component to cut the first tether 21, allowing the high-altitude balloon 11 to rise together with the pod 6 away from the cabin 1, thus completing the deployment of the high-altitude balloon 11 and improving the automation level of the deployment process.

[0080] It should be noted that the structure of the inflation component 4 can be the same as that of the high-altitude balloon inflation device, or it can be any other suitable structure with inflation function.

[0081] In embodiments of this application, the first tether 21 is, for example, a rope or a connecting line. However, it should be understood that the first tether 21 can also be any other suitable structural component.

[0082] In embodiments of this application, the control element is, for example, a PLC controller, a remote controller, or any other suitable element with control functions.

[0083] In embodiments of this application, the first tether 21 is connected to the high-altitude balloon 11, for example, via a loop on the balloon 11. The first tether 21 can also be directly tied to the high-altitude balloon 11. However, it should be understood that the first tether 21 can also be connected to the high-altitude balloon 11 in any other suitable manner.

[0084] In one embodiment of this application, such as Figure 1 and Figure 2 As shown, the cabin 1 includes a balloon placement compartment 12 and an equipment placement compartment 13, with a partition 14 between them. The high-altitude balloon 11 is located inside the balloon placement compartment 12, while the inflation assembly 4, lifting assembly 5, and pod 6 are located inside the equipment placement compartment 13. In use, the inflation assembly 4, lifting assembly 5, and pod 6 are placed in the equipment placement compartment 13, and the high-altitude balloon 11 is placed in the balloon placement compartment 12. The partition 14 separates the high-altitude balloon 11 from the equipment, preventing direct contact between the balloon 11 and the equipment and thus avoiding damage to the balloon 11.

[0085] In the embodiments of this application, the volume of the sphere placement chamber 12 is two-thirds of the volume of the chamber 1.

[0086] In embodiments of this application, the partition 14 is, for example, a tarpaulin curtain or a foam board. However, it should be understood that the partition 14 can also be any other suitable structural member with a partitioning function.

[0087] In one embodiment of this application, the inner wall of the ball placement chamber 12 is provided with a flexible element. By providing a flexible element on the inner wall of the ball placement chamber 12, the high-altitude balloon 11 will not directly contact the inner wall of the ball placement chamber 12 when it is inflated, but will first contact the flexible element, thereby avoiding damage caused by direct contact between the high-altitude balloon 11 and the ball placement chamber 12.

[0088] In embodiments of this application, for example, flexible elements are provided on the side walls of the sphere placement chamber 12. Since one side of the sphere placement chamber 12 is connected to the equipment placement chamber 13, and the sphere placement chamber 12 has only three side walls, by providing flexible elements on the three side walls of the sphere placement chamber 12, it is possible to effectively prevent the high-altitude balloon 11 from directly contacting the side walls of the sphere placement chamber 12 and causing damage when it is inflated.

[0089] In embodiments of this application, the flexible element is, for example, a foam board or a rubber sheet. However, it should be understood that the flexible element can also be any other suitable flexible structural element.

[0090] In one embodiment of this application, the side wall of the cabin 1 is provided with a tether limiting member, and the first tether 21 passes through the through hole of the tether limiting member. In use, by installing the tether limiting member on the side wall of the cabin 1, the first tether 21 is first passed through the through hole on the tether limiting member before being connected to the high-altitude balloon 11, so that the tether limiting member can limit the first tether 21 and prevent the first tether 21 from interfering with other components.

[0091] In embodiments of this application, the tethering restraint is, for example, a metal ring or a hollow plate. However, it should be understood that the tethering restraint can also be any other suitable material or shape.

[0092] In one embodiment of this application, such as Figure 1 and Figure 2 As shown, the tethering and deployment assembly 2 includes four electric winches 22, which are located at the four corners of the cabin 1. Each electric winch 22 is connected to the high-altitude balloon 11 via a first tether 21. In use, one electric winch 22 is connected to one first tether 21, meaning each electric winch 22 is connected to the high-altitude balloon 11 via the first tether 21. The electric winches 22 can keep the first tether 21 taut, thus limiting and fixing the high-altitude balloon 11 in multiple directions.

[0093] In embodiments of this application, the cabin 1 is, for example, rectangular in shape, and four electric winches 22 are, for example, located at the four right angles of the cabin 1. However, it should be understood that the cabin 1 can also be any other suitable shape, and the electric winches 22 can also be located in any other suitable position.

[0094] Furthermore, four electric winches 22 are provided, for example, at the four top corners of the cabin 1.

[0095] In one embodiment of this application, a passage is provided between the inflatable component 4 and the lifting component 5. During use, by maintaining a certain gap between the inflatable component 4 and the lifting component 5, a passage is formed between the inflatable component 4 and the lifting component 5 for workers to pass through, thereby facilitating the installation, maintenance, inspection, and other operations of components such as the inflatable component 4, the lifting component 5, and the pod 6.

[0096] In one embodiment of this application, such as Figure 1 and Figure 2 As shown, the inflation assembly 4 includes a helium storage unit 41, an inflation pipe 42, and an inflation port 43. The helium storage unit 41 is installed inside the cabin 1, and the inflation port 43 is fixedly installed on the bottom plate of the cabin 1. One end of the inflation pipe 42 is connected to the helium storage unit 41, and the other end of the inflation pipe 42 is connected to the inflation port 43. The high-altitude balloon 11 is connected to the inflation port 43. In use, the helium storage unit 41 is opened, and the helium in the helium storage unit 41 is transported to the inflation port 43 through the inflation pipe 42. Then, the helium enters the high-altitude balloon 11 through the inflation port 43, realizing the inflation operation of the high-altitude balloon 11. After the high-altitude balloon 11 is inflated, the helium storage unit 41 is closed, and the connection between the inflation port 43 and the high-altitude balloon 11 is disconnected, so that the high-altitude balloon 11 is not affected by the inflation assembly 4 when it takes off.

[0097] In one embodiment of this application, the inflation assembly 4 includes a high-pressure explosion-proof solenoid valve connected to a control unit. The inlet of the high-pressure explosion-proof solenoid valve is connected to a helium storage unit 41, and the inflation pipe 42 is connected to the outlet of the high-pressure explosion-proof solenoid valve and the inflation port 43. During use, the control unit sends an opening signal to the high-pressure explosion-proof solenoid valve, causing it to open automatically. Helium in the helium storage unit 41 can be transported through the high-pressure explosion-proof solenoid valve to the inflation pipe 42, and then to the high-altitude balloon 11, thus achieving automatic inflation of the high-altitude balloon 11. When the inflation of the high-altitude balloon 11 is completed, the control unit sends a closing signal to the high-pressure explosion-proof solenoid valve, causing it to close. Helium in the helium storage unit 41 can no longer be transported to the high-altitude balloon 11, thereby automatically stopping the inflation of the high-altitude balloon 11.

[0098] In one embodiment of this application, the inflation assembly 4 includes a mass flow meter disposed in the inflation pipe 42 and connected to a control unit. The mass flow meter is used to detect the gas flow rate delivered into the high-altitude balloon 11. During use, when helium from the helium storage unit 41 is delivered into the high-altitude balloon 11, it first passes through the mass flow meter. The mass flow meter can detect the gas flow rate delivered into the high-altitude balloon 11 and send the detection data to the control unit. When the mass flow meter detects that the gas flow rate delivered into the high-altitude balloon 11 reaches a preset value, the control unit controls the high-pressure explosion-proof solenoid valve to close. This achieves automatic detection of the gas content inside the high-altitude balloon 11 and accurately closes the high-pressure explosion-proof solenoid valve, preventing excessive or insufficient gas in the high-altitude balloon 11.

[0099] In one embodiment of this application, the inflation assembly 4 further includes a pressure sensor installed in the helium storage unit 41 and connected to a control unit. The pressure sensor is used to detect the gas pressure inside the helium storage unit 41. During use, by real-time monitoring of the gas pressure inside the helium storage unit 41, the pressure sensor can determine how much helium has been supplied, and thus the amount of gas inside the high-altitude balloon 11. When the pressure sensor detects that the gas pressure in the helium storage unit 41 has dropped to a preset value, it indicates that the high-altitude balloon 11 is fully inflated. Since the pressure sensor is connected to the control unit, it can transmit the detection result to the control unit. The control unit can then close the helium storage unit 41 when the high-altitude balloon 11 is fully inflated, thus stopping the supply of gas to the high-altitude balloon 11 in a timely manner. This achieves automatic detection of the gas content inside the high-altitude balloon 11 and accurately closes the high-pressure explosion-proof solenoid valve, preventing the high-altitude balloon 11 from having too much or too little gas.

[0100] In the embodiments of this application, the inflation component 4 may include both a pressure sensor and a mass flow meter, thereby improving the accuracy of gas content detection inside the high-altitude balloon 11, enabling more precise closure of the high-pressure explosion-proof solenoid valve, and further ensuring that there is neither too much nor too little gas inside the high-altitude balloon 11.

[0101] In one embodiment of this application, the inflation port 43 is equipped with an electric gripper connected to a control unit. The electric gripper is used to grip the high-altitude balloon 11. During use, the inflation port 43 is connected to the high-altitude balloon 11, allowing helium in the helium storage unit 41 to enter the high-altitude balloon 11 through the inflation port 43. In the early stage of inflation of the high-altitude balloon 11, the control unit controls the electric gripper to grip the high-altitude balloon 11, thereby limiting the movement of the high-altitude balloon 11 and preventing it from shaking or shifting significantly during inflation.

[0102] It should be noted that after the high-altitude balloon 11 is inflated, the control unit controls the electric claw to open, and at this time the high-altitude balloon 11 is limited and fixed by the first tether 21.

[0103] In one embodiment of this application, a second tether is provided between the pod 6 and the lifting assembly 5. The second tether is adapted to fix the pod 6 to the lifting assembly 5. In use, the pod 6 and the lifting assembly 5 are connected together by the second tether to prevent the pod 6 from detaching from the lifting assembly 5 when the lifting assembly 5 lifts the pod 6.

[0104] In the embodiments of this application, a second cutting element is provided at the second tether location. The second cutting element is connected to the control element and is adapted to cut the second tether. When the high-altitude balloon 11 is fully inflated, the tether deployment and retraction assembly 2 gradually releases the first tether 21 until the high-altitude balloon 11 is completely upright. At this time, the first cutting element cuts the first tether 21, and the second cutting element cuts the second tether, so that the high-altitude balloon 11 can lift the pod 6 into the air under the action of buoyancy.

[0105] In embodiments of this application, the first and second cutting elements are, for example, cutters. However, it should be understood that the first and second cutting elements can also be any other suitable structure.

[0106] In one embodiment of this application, the high-altitude balloon launch container includes a balloon clamp located below the air inlet of the high-altitude balloon 11. During use, the balloon clamp on the high-altitude balloon 11 helps limit its size before ascent, preventing excessive windward surface area and thus minimizing its sway, thereby maximizing its safety. Opening the balloon clamp during ascent allows the balloon to take off normally.

[0107] In one embodiment of this application, the lifting assembly 5 includes, for example, a lifting motor and a lifting platform, with the pod 6 mounted on the lifting platform. The lifting motor can drive the lifting platform to move up and down. The lifting assembly 5 may also include a lifting cylinder and a lifting plate, with the pod 6 mounted on the lifting plate. The lifting cylinder can drive the lifting plate to move up and down. However, it should be understood that the lifting assembly 5 can also be any other suitable structure.

[0108] According to the embodiments of the third aspect of this application, such as Figure 9 As shown, the high-altitude balloon launching method includes:

[0109] 101. Transport the high-altitude balloon inflation device to the designated distribution site, open the top plate of the cabin 1, so that the high-altitude balloon 11 can be directly connected to the outside world;

[0110] Specifically, after transporting the high-altitude balloon inflation device to the designated launch site, the high-altitude balloon inflation device is deployed. Based on the ground wind conditions at the launch site, the side containing the lifting component 5 and the inflation component 4 is placed downwind. The status of the control components and the inflation component 4 is checked, and the entire system is powered on.

[0111] 102. Control the inflation component 4 to inflate the high-altitude balloon 11 until the high-altitude balloon 11 is fully inflated;

[0112] Specifically, the inflation component 4 delivers helium gas into the high-altitude balloon 11 through the air inlet, gradually filling the high-altitude balloon 11 with helium and giving it buoyancy. Once the high-altitude balloon 11 is fully inflated, the inflation component 4 disengages from the air inlet of the high-altitude balloon 11 and closes the air inlet of the high-altitude balloon 11.

[0113] It should be noted that during the early stage of inflation of the high-altitude balloon 11, the high-altitude balloon 11 is limited and fixed by the electric clamp. After inflation is completed, the electric clamp is opened and the high-altitude balloon 11 is limited and fixed by the first tether 21.

[0114] 103. Control the first tether 21 retraction assembly 2 to start releasing the first tether 21, so that the high-altitude balloon 11 is continuously raised until the high-altitude balloon 11 is in an upright state;

[0115] Specifically, the first tether 21 deployment and take-up assembly 2 gradually releases the first tether 21, causing the high-altitude balloon 11 to rise continuously under the action of buoyancy. When the high-altitude balloon 11 is in a completely upright state, the first tether 21 deployment and take-up assembly 2 stops releasing the first tether 21, so that the high-altitude balloon 11 remains in an upright state.

[0116] 104. Control the lifting assembly 5 to raise the pod 6, so that the pod 6 is higher than the body 1;

[0117] Specifically, as the first tether 21 releases the first tether 21, the lifting assembly 5 lifts the pod 6, making the pod 6 higher than the body 1, thus preventing a collision between the pod 6 and the body 1.

[0118] 105. Cut the first tether 21, so that the high-altitude balloon 11 can lift the gondola 6 into the air.

[0119] Specifically, when the gondola 6 is higher than the cabin 1 and the high-altitude balloon 11 is in a completely upright state, the first tether 21 is cut, causing the high-altitude balloon 11 to rise under the action of buoyancy, and driving the gondola 6 into the air, realizing the automatic release of the high-altitude balloon 11 and improving the degree of automation.

[0120] The high-altitude balloon launching methods in related technologies complete the inflation of the high-altitude balloon 11 within a closed space, which is only suitable for small balloons. However, the high-altitude balloon launching method of this application opens the top cover of the cabin 1 before the high-altitude balloon 11 is inflated, and uses components such as the first tether 21 to limit and fix the high-altitude balloon 11, which can reduce the limitation of the cabin 1 on the volume of the high-altitude balloon 11, and thus can be applied to small and medium-sized high-altitude balloons 11.

[0121] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application and should be covered within the scope of the claims of this application.
