[0066] like Figure 1 As shown, the experimental apparatus 100 for simulating a space environment (hereinafter referred to as "experimental apparatus 100") provided in this embodiment of the application includes a reaction chamber 10 and a vacuum chamber 20. The reaction chamber 10 is located inside the vacuum chamber 20 and is connected to the vacuum chamber 20 by means of suspension. However, this is not the only possibility; for example, the reaction chamber 10 can also be connected to the bottom of the vacuum chamber 20 by a bracket. The reaction chamber 10 includes a first door 120 and a first chamber body 110, and the vacuum chamber 20 includes a second door 220 and a second chamber body 210. The first door 120 and the first chamber body 110, as well as the second door 220 and the second chamber body 210, are all hinged, but are not limited to hinged connections. The first door 120 and the first chamber body 110, and the second door 220 and the second chamber body 210 are sealed with sealing rings to achieve a vacuum environment.

[0067] Both the reaction chamber 10 and the vacuum chamber 20 are in a vacuum environment to simulate the space environment. The reaction chamber 10 is located inside the vacuum chamber 20 so that both the inside and outside of the reaction chamber 10 are in a vacuum environment. This allows the internal and external pressures of the reaction chamber 10 to be relatively balanced, thereby reducing the impact of the sealing effect of the test device 100 on the test during ultra-low temperature. At the same time, it allows the test material to be tested in a high vacuum environment, thus obtaining more accurate test data.

[0068] In an optional embodiment, the test apparatus 100 further includes a stage 130 and a slide rail 140. The stage 130 is located inside the reaction chamber 10 and is used to place the test substance. The slide rail 140 is connected to the bottom of the first chamber body 110 and is slidably connected to the stage 130 so as to facilitate the removal or placement of the test substance in the reaction chamber 10.

[0069] In an optional embodiment, the vacuum chamber 20 and the reaction chamber 10 are respectively provided with a first visualization window 230 and a second visualization window 150, the first visualization window 230 and the second visualization window 150 being positioned correspondingly to simulate illumination conditions and facilitate observation through the visualization windows.

[0070] Furthermore, the vacuum chamber 20 may also be provided with multiple first visualization windows 230, which are located on the second chamber body 210 and the second door 220; the reaction chamber 10 may also be provided with multiple second visualization windows 150, which are located on the first chamber body 110 and the first door 120, so as to simulate different light intensity conditions and make it easier to observe the state and changes of the test substance from different directions.

[0071] like Figure 2 As shown, the test apparatus 100 also includes an input / output component 30, a detection component 40, an adjustment component 50, and a controller. The input / output component 30 is used to input and output media into the reaction chamber 10, and the media includes at least gas, powder, and liquid.

[0072] The detection component 40 is used to detect environmental parameter values ​​within the reaction chamber 10 and the vacuum chamber 20. The environmental parameters include at least temperature, vacuum level, pressure, and electric field.

[0073] The regulating component 50 is used to regulate the amount of medium input and output from the input / output component 30 to the reaction chamber 10.

[0074] The controller is located outside the vacuum chamber 20 and is electrically connected to the input / output component 30, the detection component 40, and the adjustment component 50. The controller sends adjustment commands to the adjustment component 50 based on the detection values ​​of the detection component 40. The adjustment component 50 adjusts the input / output component 30 based on the adjustment commands to ensure that the values ​​of multiple environmental parameters within the reaction chamber 10 are within preset ranges.

[0075] The above-mentioned test device 100 can adjust and control the values ​​of multiple environmental parameters in the reaction chamber 10, thereby simulating the space environment; adjusting and controlling the multiple environmental parameters in the reaction chamber 10 within the preset value range can ensure the accuracy of the test of the test material in the reaction chamber 10.

[0076] This experimental device 100 can simulate the space environment to test the physical and chemical properties of different substances and materials under different space environmental conditions. It can simulate application scenarios and accelerated aging conditions to confirm whether aviation and aerospace equipment and component materials can be used in this environment, thus providing assistance in material selection. It can also conduct simulation experiments without going to the space environment, which greatly reduces the testing cost, shortens the testing cycle, improves the testing efficiency, and increases the possibility, flexibility and reliability of space research.

[0077] In an alternative embodiment, such as Figures 3 to 6 As shown, the input / output assembly 30 includes a compressor 311, a cold head 312, and a cooling belt 313. The compressor 311 is located outside the vacuum chamber 20, and the cold head 312 is connected to the vacuum chamber 20 and generates cooling capacity under the action of the compressor 311. One end of the cooling belt 313 is connected to the cold head 312, and the other end is connected to the inside of the reaction chamber 10, so as to deliver cooling capacity to the inside of the reaction chamber 10 to simulate the ultra-low temperature environment in space.

[0078] Furthermore, the detection component 40 includes a temperature sensor 410, which is connected to the reaction chamber 10 and used to detect the temperature inside the reaction chamber 10. The temperature sensor 410 feeds back the detected temperature value to the controller, which determines whether the current temperature value is within a preset temperature range. When the controller determines that the current temperature exceeds the preset temperature range, it sends an adjustment command to the adjustment component 50 to adjust the temperature.

[0079] Specifically, the input / output assembly 30 also includes a heater 314, which is connected to the reaction chamber 10 and used to generate heat. The regulating assembly 50 includes a heat exchanger 510, which is connected to the outside of the reaction chamber 10 and located inside the vacuum chamber 20. The heat exchanger 510 connects the reaction chamber 10, the cooling belt 313, and the heater 314. The heat exchanger 510 is used to exchange heat generated by the heater 314 with cold energy transported by the cooling belt 313 to regulate the temperature inside the reaction chamber 10.

[0080] In this embodiment of the application, the temperature can be adjusted by using heat exchanger 510 to improve the accuracy of the temperature in reaction chamber 10, thereby improving the reliability of the test device 100.

[0081] In an optional embodiment, the input / output component 30 further includes a molecular pump 320 located outside the vacuum chamber 20 and used to evacuate the vacuum chamber 20 and the reaction chamber 10 so that both the vacuum chamber 20 and the reaction chamber 10 are in a vacuum environment.

[0082] Furthermore, the detection component 40 includes a vacuum gauge 420, which is connected to the vacuum chamber 20 and used to detect the vacuum level inside the vacuum chamber 20. The vacuum gauge 420 feeds back the detected vacuum level to the controller.

[0083] The regulating assembly 50 also includes a first vacuum valve 520 and a second vacuum valve 530. The first vacuum valve 520 is connected between the reaction chamber 10 and the molecular pump 320, and is located outside the vacuum chamber 20. The first vacuum valve 520 is used to regulate the connection between the reaction chamber 10 and the external input. The second vacuum valve 530 is connected between the vacuum chamber 20 and the molecular pump 320, and is located outside the vacuum chamber 20. It is also used to regulate the connection between the vacuum chamber 20 and the external input. The controller determines whether the vacuum level is within a preset vacuum level range based on the vacuum level detected by the vacuum gauge 420. When the vacuum level detected by the reaction chamber 10 exceeds the preset vacuum level range, the controller sends an regulating command to the first vacuum valve 520 to regulate the connection between the reaction chamber 10 and the external input. As an example, the controller sends an opening command to the second vacuum valve 530, which opens to evacuate the vacuum chamber 20 using the molecular pump 320 until the vacuum level detected by the vacuum gauge 420 is within the preset vacuum level range.

[0084] It should be noted that the first vacuum valve 520 can detect the vacuum level in the reaction chamber 10, and the second vacuum valve 530 can detect the vacuum level in the vacuum chamber 20. When the molecular pump is not connected to the first vacuum valve 520 and the second vacuum valve 530, the vacuum gauge 420 can be used to detect the vacuum level in the vacuum chamber 20, and the pressure transmitter 430 can be used to detect the vacuum level in the reaction chamber 10.

[0085] In an optional embodiment, the input / output component 30 further includes a gas tank 330, which is connected to the interior of the reaction chamber 10 and used to input gas into the reaction chamber 10. As an example, if the simulated space environment contains a large amount of carbon dioxide gas, the gas tank 330 is used to input carbon dioxide gas into the reaction chamber 10.

[0086] Furthermore, the detection assembly 40 also includes a pressure transmitter 430 and a pressure relief valve 440. The pressure transmitter 430 is located outside the vacuum chamber 20 and is used to detect the pressure inside the reaction chamber 10. The pressure relief valve 440 is located outside the vacuum chamber 20 and connected to the pressure transmitter 430. The pressure relief valve 440 is used to monitor the pressure inside the reaction chamber 10. When the pressure value inside the reaction chamber 10 is greater than a preset pressure range, the pressure relief valve 440 relieves pressure in the reaction chamber 10 to bring the pressure value inside the reaction chamber 10 within the preset pressure range. When the pressure value inside the reaction chamber 10 is less than the preset pressure range, the flow rate of gas entering the reaction chamber 10 is increased by adjusting the first vacuum valve 520 connected between the gas tank 330 and the reaction chamber 10.

[0087] In this embodiment, the pressure value inside the reaction chamber 10 is detected by the pressure transmitter 430, and the pressure is adjusted by the first vacuum valve 520 and the pressure transmitter 430 so that the pressure inside the reaction chamber 10 is within the preset pressure range, thereby ensuring the test accuracy and reliability of the test device 100.

[0088] In an optional embodiment, the input / output assembly 30 further includes a liquid injector 340 and a powder blower 350. The liquid injector 340 is located outside the vacuum chamber 20 and is used to inject liquid into the reaction chamber 10 to simulate a space environment containing water vapor. The powder blower 350 is also located outside the vacuum chamber 20 and is used to blow powder into the reaction chamber 10 to simulate a space environment containing powder, such as a space environment containing silicate minerals and iron oxides.

[0089] The input / output component 30 is connected to the reaction chamber and the vacuum chamber via pipes. The pipes are connected to the reaction chamber and the vacuum chamber by means of welding, but are not limited to welding.

[0090] As an example, such as Figure 4 As shown, the powder blower 350 is connected to the vacuum chamber 20 via the first powder blowing pipe 351 and to the reaction chamber 10 via the second powder blowing pipe 352. The first powder blowing pipe 351 and the second powder blowing pipe 352 are connected and fixed by a clamping assembly. Also as an example, the gas tank 330 is connected to the vacuum chamber 20 via the first gas blowing pipe 331 and to the reaction chamber 10 via the second gas blowing pipe 332. The first gas blowing pipe 331 and the second gas blowing pipe 332 are connected and fixed by a clamping assembly.

[0091] In an optional embodiment, the input / output component 30 further includes two vacuum electrodes 360. One vacuum electrode 360 ​​is connected to the outside of the vacuum chamber 20, and the other vacuum electrode 360 ​​is located inside the vacuum chamber 20 and connected to the reaction chamber 10. The two vacuum electrodes 360 are used to provide a strong electric field to simulate space environments such as gas corona discharge, droplet breakup, and particle movement under a strong electric field by inputting a high-voltage DC or AC power signal.

[0092] The above-mentioned test device 100 can conduct material tests in advance, which can improve the reliability of the spacecraft in actual use and reduce the risk of material damage or adverse reactions caused by the space environment, thus preventing it from working.

[0093] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this application that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of this application and do not limit the scope of protection of this patent application.
