[0027] Spacecraft have extremely high requirements for the stability of gas storage and supply methods. However, in practical applications, due to the fact that traditional gas storage and supply methods are often bulky and complex to operate, they often have difficulty adapting to the compact structure and highly integrated requirements of modern spacecraft. The traditional technical route usually uses high-pressure gas cylinders as the main body, which are connected by various single-function components through conduits, brackets, etc. The main problems are as follows: The system pipeline structure is complex, there are a large number of pipeline joints, and there are many leakage points; restricted by the structural space, it is difficult to bend the pipeline; to meet the requirements of long-term pre-packaged storage of high-pressure gas, the connecting conduits between the inflation valve, the electric explosion valve, the gas cylinder, etc. must adopt an on-line welding structure, with poor processability and low production efficiency; the pipeline becomes a weak link in the structure, and the robustness of the overall structure to withstand dynamic loads such as vibration and impact needs to be improved.

[0028] The manufacturing process of the gas storage and supply system involves multiple precision machining and assembly steps, with high requirements for equipment precision and worker skills. The complex manufacturing process not only increases production costs but also may lead to low production efficiency, further driving up the system cost. The aerospace integrated pre-packaged gas storage and supply system needs to highly integrate multiple functional modules such as gas storage, supply, monitoring, and control. This process requires solving the compatibility and matching problems between various components, increasing the difficulty and cost of system integration. In addition, in practical applications, there are still problems of excessive volume and weight, which to a certain extent limit its application in spacecraft. Especially in the case of limited internal space in the spacecraft, the bulky gas storage and supply system will occupy valuable space resources and affect the layout and installation of other equipment.

[0029] In addition, due to the low degree of system integration, additional connectors and pipelines are required between each functional module, which also increases the overall volume of the system. This not only increases the structural complexity of the spacecraft but may also have an adverse impact on the overall performance and stability of the spacecraft.

[0030] Therefore, some embodiments of this application provide a gas storage and supply integrated device. The gas storage and supply integrated device aims at the problem that the traditional gas storage and supply methods are difficult to meet the high integration requirements of spacecraft. Through the integral printing technology, the spherical gas cylinder and the mounting bracket are integrally formed, and the valve interfaces are arranged on the device in an embedded manner. At the same time, the connecting flow channels between the various functional components are prefabricated on the main body of the device, realizing the high integration of the gas storage and supply device and eliminating all internal conduits. Thus, it can not only improve the integration and sealing performance of the gas storage and supply system but also reduce costs.

[0031] The following combines Figures 1 to 3 , to illustrate the gas storage and supply integrated device provided by some embodiments of this application.

[0032] As Figure 1 shown, a gas storage and supply integrated device provided by some embodiments of this application includes a gas cylinder 10 and a mounting bracket. The mounting bracket includes a mounting table and mounting supports on both sides of the mounting table. The middle part of the mounting table is in gas communication with the bottom of the gas cylinder 10. The inside of the mounting table has a connecting flow channel, and the end face of the mounting table has an external port that is in gas communication with the inside through the connecting flow channel. The gas cylinder 10 and the mounting table are integrally formed. The connecting flow channel includes a high-pressure gas flow channel 20 and a low-pressure gas flow channel 30 arranged along a preset direction. An external interface is inserted in an embedded manner at the external port. The external interface includes: a pressure reducing valve interface 41 and an electric blasting valve interface 42 provided between the high-pressure gas flow channel 20 and the low-pressure gas flow channel 30, a first high-pressure gas output interface 21 and a second high-pressure gas output interface 22 respectively provided at both ends of the high-pressure gas flow channel 20, and a first low-pressure gas output interface 31 and a second low-pressure gas output interface 32 respectively provided at both ends of the low-pressure gas flow channel 30.

[0033] The gas cylinder 10 can adopt pre-packaging technology to pre-store gas in a special container in the form of high pressure and high density, achieving efficient storage and rapid supply of gas. The pre-packaging technology not only reduces the volume and weight of the storage equipment, but also improves the utilization efficiency of the gas. At the same time, the pre-packaging container usually has good airtightness and stability, which can ensure the long-term preservation and transportation safety of the gas.

[0034] The middle part of the installation platform is in gas communication with the bottom of the gas cylinder 10 to ensure that the gas can smoothly enter the connection flow channel inside the installation platform. The connection flow channel includes a high-pressure air flow channel 20 and a low-pressure air flow channel 30 arranged along a preset direction, which are used to distribute and guide the gas flow to different external ports. An external interface is inserted in an embedded manner at the external port, including a pressure reducing valve interface 41 and an electric blasting valve interface 42 provided between the high-pressure air flow channel 20 and the low-pressure air flow channel 30. First high-pressure gas output interfaces 21 and second high-pressure gas output interfaces 22 are respectively provided at both ends of the high-pressure air flow channel 20, and first low-pressure gas output interfaces 31 and second low-pressure gas output interfaces 32 are respectively provided at both ends of the low-pressure air flow channel 30, which is convenient for connection and use.

[0035] The gas cylinder 10 and the installation platform adopt a highly integrated design and are integrally formed by 3D integral printing technology, which greatly improves the compactness and manufacturing precision of the device, and ensures the stability and efficiency of gas storage and supply. Through the iterative optimization of the three-dimensional model and printing scheme, a structural body printing process scheme is formed. By using structural simulation analysis and printing process modeling analysis means, the stress matching problem and dimensional stability problem in the printing process of complex pressure-bearing structures can be solved.

[0036] In some embodiments, a safety valve interface 33, a low-pressure test interface 34 and a first pressure reducing valve test interface 35 are further provided on the low-pressure air flow channel 30, and a high-pressure test interface 23 and a second pressure reducing valve test interface 24 are further provided on the high-pressure air flow channel 20.

[0037] The safety valve interface 33 is used to connect a safety valve. When the gas pressure rises above a preset safety value, the safety valve will automatically open and release some gas into the atmosphere to prevent the pressure from continuing to rise and possibly causing damage to the equipment or system. That is to say, when the outlet pressure of the pressure reducing valve is overpressure, the safety valve opens to discharge the overpressure gas and avoid overpressure explosion of the downstream low-pressure chamber.

[0038] A first pressure reducing valve test interface 35 and a second pressure reducing valve test interface 24 can be provided in the low-pressure area downstream of the pressure reducing valve. A low-pressure test interface 34 is left downstream of the pressure reducing valve test interface. The first pressure reducing valve test interface 35 and the second pressure reducing valve test interface 24 can be used for debugging the pressure reducing valve. Before the product is delivered, these test interfaces allow technicians to conduct detailed debugging of the pressure reducing valve to ensure that its performance meets the preset standards. Once the test is passed, these interfaces will be connected with plugs to ensure the sealing performance and safety of the device during formal use.

[0039] The low-pressure test interface 34 can be used to detect the sealing performance. Through this interface, technicians can restart the device and detect the sealing performance of the downstream part of the pressure reducing valve, so as to ensure that there is no gas leakage in the actual use of the device.

[0040] A high-pressure test interface 23 and a second pressure reducing valve test interface 24 are also provided on the high-pressure air flow path 20. The high-pressure test interface 23 can be used to inflate and test the airtightness from downstream of the electro-explosion valve diaphragm to upstream of the pressure reducing valve, that is, it can inflate and test the airtightness of the first flow path, the second flow path and the high-pressure air flow path 20.

[0041] In some embodiments, a first flow path communicating with the high-pressure air flow path 20 is provided at the electro-explosion valve interface 42, a second flow path communicating with the high-pressure air flow path 20 and a third flow path communicating with the low-pressure air flow path 30 are respectively provided at the pressure reducing valve interface 41. The internal gas at the electro-explosion valve interface 42 flows to both ends of the high-pressure air flow path 20 through the first flow path. Among them, part of the gas enters the downstream high-pressure chamber after passing through the first high-pressure gas output interface 21 and the second high-pressure gas output interface 22 respectively, and the other part of the gas passes through the second flow path and the third flow path in sequence and then enters the first low-pressure gas output interface 31 and the second low-pressure gas output interface 32 and enters the downstream low-pressure chamber at the same time.

[0042] A first flow path communicating with the high-pressure air flow path 20 is provided at the electro-explosion valve interface 42, which enables the gas inside the electro-explosion valve interface 42 to flow to both ends of the high-pressure air flow path 20. In this process, part of the gas enters the downstream high-pressure chamber through the first high-pressure gas output interface 21 and the second high-pressure gas output interface 22 respectively, providing the required high-pressure gas for the downstream equipment or system.

[0043] At the same time, the other part of the gas passes through the second flow path communicating with the high-pressure air flow path 20, after being decompressed, passes through the third flow path communicating with the low-pressure air flow path 30, and then enters the first low-pressure gas output interface 31 and the second low-pressure gas output interface 32 and enters the downstream low-pressure chamber at the same time, providing a stable low-pressure gas supply for the equipment or system that requires low-pressure gas.

[0044] In some embodiments, an inflation valve interface 11 is provided on the gas cylinder 10.

[0045] The gas cylinder 10 is provided with an inflation valve interface 11, enabling the gas cylinder 10 to be inflated through this interface during use, thereby allowing for repeated use and reducing the usage cost.

[0046] In some embodiments, the installation support includes a first support portion and a second support portion. The first support portion and the second support portion are oppositely arranged along a preset direction. The first support portion is provided on one side of the installation table close to the electric explosion valve interface 42, and the second support portion is provided on one side of the installation table close to the pressure reducing valve interface 41.

[0047] The installation support serves as the basic structure of the gas storage and supply integrated device, used to support and fix the entire device. The installation support includes a first support portion and a second support portion, which are oppositely arranged along a preset direction, ensuring the stability and balance of the installation. The first support portion is located on one side of the installation table close to the electric explosion valve interface 42, while the second support portion is located on one side of the installation table close to the pressure reducing valve interface 41.

[0048] In some embodiments, the first support portion includes a first bottom plate, a first support rod, and a second support rod connected to the first bottom plate. The first bottom plate is arranged along a direction perpendicular to the preset direction. The first support rod is connected to the high-pressure air flow channel 20, and the second support rod is connected to the low-pressure air flow channel 30.

[0049] The first bottom plate serves as the foundation of the first support portion. The first bottom plate is arranged along a direction perpendicular to the preset direction, providing a stable support surface for the entire support structure. The first support rod and the second support rod are respectively connected to the high-pressure air flow channel 20 and the low-pressure air flow channel 30, further enhancing the stability and load-bearing capacity of the support structure.

[0050] In some embodiments, the second support portion includes a third support rod, a fourth support rod, and a connecting rod connecting the third support rod and the fourth support rod. The third support rod is connected to the high-pressure air flow channel 20, and the fourth support rod is connected to the low-pressure air flow channel 30.

[0051] The third support rod and the fourth support rod can be respectively connected to the high-pressure air flow channel 20 and the low-pressure air flow channel 30 to provide additional support for the device. The third support rod, the fourth support rod, and the connecting rod together form a stable triangular structure, further improving the rigidity and stability of the support portion.

[0052] In some embodiments, installation holes are provided at the bottoms of the first bottom plate, the third support rod, and the fourth support rod.

[0053] Mounting holes are provided at the bottom of the first base plate, the bottom of the third support rod, and the bottom of the fourth support rod for fixing the mounting support to a mounting table or other basic structure. These mounting holes are connected to the basic structure through fasteners such as bolts and nuts, ensuring a firm connection between the mounting support and the basic structure. The design of the mounting holes makes the installation and disassembly of the mounting support more convenient and fast, and also facilitates subsequent maintenance and repair work.

[0054] In some embodiments, a high-pressure pressure sensor interface 50 and a low-pressure pressure sensor interface 60 are provided at the bottom of the mounting table. The high-pressure pressure sensor interface 50 is connected to the gas cylinder 10, and the low-pressure pressure sensor interface 60 is connected to the first low-pressure gas output interface 31.

[0055] The high-pressure pressure sensor interface 50 is used to connect a high-pressure pressure sensor, and the high-pressure pressure sensor is used to monitor the pressure of the high-pressure gas in the gas cylinder 10. Through real-time monitoring, it can be ensured that the pressure in the gas cylinder 10 always remains within a safe and appropriate range, avoiding potential risks caused by too high or too low pressure. The low-pressure pressure sensor interface 60 is used to connect a low-pressure pressure sensor, and the low-pressure pressure sensor is used to monitor the gas pressure in the downstream low-pressure chamber.

[0056] When the electric blasting valve detonates, the high-pressure gas flow channel 20 is opened, and the high-pressure gas flows to the downstream high-pressure chamber through the first high-pressure gas output interface 21 and the second high-pressure gas output interface 22; at the same time, part of the high-pressure gas enters the pressure reducing valve for pressure reduction, and then flows to the downstream low-pressure chamber through the first low-pressure gas output interface 31 and the second low-pressure gas output interface 32. During this process, the low-pressure pressure sensor monitors the pressure of the low-pressure gas in real time to ensure the stability and safety of the system operation.

[0057] When the system is in the telemetry state, these two pressure sensor interfaces will connect the electrical signals for real-time pressure detection. This telemetry function not only improves the convenience of the system, but also enables users to remotely monitor the pressure conditions of the gas cylinder 10 and downstream equipment, and discover problems in time and take corresponding measures.

[0058] In actual situations, these two pressure sensor interfaces also have important applications during storage. They can be used to monitor the pressure in the pre-packaged gas cylinder 10. If the high-pressure pressure sensor shows a decrease in pressure, it may indicate that there is a leakage point in the gas cylinder 10 in the pre-packaged state. At this time, the user needs to disassemble and detect it again to ensure the integrity and safety of the gas cylinder 10.

[0059] In some embodiments, the printing material of the device is titanium alloy.

[0060] The high strength and toughness of the titanium alloy enable the device to withstand high working pressures and temperature changes, thus ensuring the stability and durability of the device. At the same time, the corrosion resistance of the titanium alloy enables the device to maintain good performance even in harsh environments, extending its service life.

[0061] Those of ordinary skill in the art can understand that the above embodiments are specific examples for implementing the present application, and in actual applications, various changes can be made to them in form and details without departing from the spirit and scope of the present application.
