[0066] like Figure 1 As shown, the test device 100 for simulating a space environment provided in the embodiment of the present application (hereinafter referred to as "test device 100") includes a reaction chamber 10 and a vacuum chamber 20. The reaction chamber 10 is located inside the vacuum chamber 20. The reaction chamber 10 is connected to the vacuum chamber 20 by hoisting, but it is certainly not limited to this. 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 body 120 and a first chamber body 110. The vacuum chamber 20 includes a second door body 220 and a second chamber body 210. The first door body 120 and the first chamber body 110, and the second door body 220 and the second chamber body 210 are all hinged, but it is certainly not limited to hinged. The first door body 120 and the first chamber body 110, and the second door body 220 and the second chamber body 210 are sealed by a sealing ring 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 the inside and outside of the reaction chamber 10 are both in a vacuum environment, which can make the internal and external pressures of the reaction chamber 10 relatively balanced, thereby reducing the impact of the sealing effect of the test device 100 on the test at ultra-low temperature, and at the same time, the test material can be tested in a high vacuum environment, thereby obtaining more accurate test data.

[0068] In an optional embodiment, the test device 100 also includes a carrier 130 and a slide rail 140. The carrier 130 is located in the reaction chamber 10 and is used to place the substance to be tested. The slide rail 140 is connected to the bottom of the first chamber body 110, and the slide rail 140 is slidably connected to the carrier 130 to facilitate taking out or putting in the substance to be tested 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 , and the first visualization window 230 and the second visualization window 150 are located correspondingly to simulate lighting conditions and facilitate observation through the visualization windows.

[0070] Furthermore, the vacuum chamber 20 may also be provided with a plurality of first visualization windows 230, and the plurality of first visualization windows 230 are located on the second chamber body 210 and the second door body 220; the reaction chamber 10 may also be provided with a plurality of second visualization windows 150, and the plurality of second visualization windows 150 are located on the first chamber body 110 and the first door body 120, so as to simulate illumination conditions of different intensities, and at the same time, it is more convenient to observe the state and changes of the test substance from different directions.

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

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

[0073] The regulating component 50 is used to regulate the amount of the medium input and output from the input and 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 an adjustment instruction to the adjustment component 50 based on the detection value of the detection component 40, and the adjustment component 50 adjusts the input-output component 30 based on the adjustment instruction so that the values ​​of multiple environmental parameters in the reaction chamber 10 are within the preset value range.

[0075] The above test device 100 can realize the adjustment and control of multiple environmental parameter values ​​in the reaction chamber 10, thereby realizing the simulation of the space environment; adjusting and controlling multiple environmental parameters in the reaction chamber 10 within the preset value range can ensure the accuracy of the test of the test substance in the reaction chamber 10.

[0076] The test device 100 can simulate the space environment to test the physical and chemical properties of different substances and materials in different space environment states, and can simulate application scenarios and accelerated aging conditions, so as to confirm whether aviation, aerospace equipment and component materials can be used in this environment, providing assistance for material selection; it can also perform simulated test operations without going to the space environment, which greatly reduces the test cost, shortens the test cycle, and also improves the test efficiency, and increases the possibility, flexibility and reliability of space research.

[0077] In an alternative embodiment, if Figures 3 to 6 As shown, the input-output assembly 30 includes a compressor 311, a cold head 312 and a cold conduction 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 cold energy under the action of the compressor 311. One end of the cold conduction belt 313 is connected to the cold head 312, and the other end is connected to the inside of the reaction chamber 10, so that the cold energy can be transported 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 is used to detect the temperature inside the reaction chamber 10. The temperature sensor 410 feeds back the detected temperature value to the controller, and the controller determines whether the current temperature value is within the preset temperature value range. When the controller determines that the current temperature exceeds the preset temperature value range, it sends an adjustment instruction to the adjustment component 50 to achieve temperature adjustment.

[0079] Specifically, the input-output assembly 30 further 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 is located in the vacuum chamber 20. The heat exchanger 510 is connected to 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 transported by the cooling belt 313 to regulate the temperature in the reaction chamber 10.

[0080] In the embodiment of the present application, the use of the heat exchanger 510 to adjust the temperature can improve the accuracy of the temperature in the reaction chamber 10 , thereby improving the reliability of the test of the test device 100 .

[0081] In an optional embodiment, the input-output assembly 30 further includes a molecular pump 320, which is located outside the vacuum chamber 20 and is 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 is used to detect the vacuum degree inside the vacuum chamber 20 , and the vacuum gauge 420 feeds back the detected vacuum degree to the controller.

[0083] The regulating assembly 50 further 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 adjust 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. The second vacuum valve 530 is located outside the vacuum chamber 20 and is used to adjust the connection between the vacuum chamber 20 and the external input. The controller determines whether it is within a preset vacuum range based on the vacuum degree detected by the vacuum gauge 420. When the vacuum degree detected by the reaction chamber 10 exceeds the preset vacuum range, the controller sends an adjustment instruction to the first vacuum valve 520 to use the first vacuum valve 520 to adjust the connection between the reaction chamber 10 and the external input. As an example, the controller sends an opening instruction to the second vacuum valve 530, and the second vacuum valve 530 is opened to evacuate the vacuum chamber 20 using the molecular pump 320 until the vacuum degree detected by the vacuum gauge 420 is within the preset vacuum range.

[0084] It should be noted that the first vacuum valve 520 can detect the vacuum degree in the reaction chamber 10, and the second vacuum valve 530 can detect the vacuum degree 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 degree in the vacuum chamber 20, and the pressure transmitter 430 can be used to detect the vacuum degree in the reaction chamber 10.

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

[0086] Further, 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 in the reaction chamber 10. The pressure relief valve 440 is located outside the vacuum chamber 20 and is connected to the pressure transmitter 430. The pressure relief valve 440 is used to monitor the pressure in the reaction chamber. When the pressure value in the reaction chamber 10 is greater than the preset pressure range, the pressure relief valve 440 releases the pressure in the reaction chamber 10 so that the pressure value in the reaction chamber 10 is within the preset pressure range. When the pressure value in the reaction chamber 10 is less than the preset pressure range, the flow rate of the gas input into 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] The embodiment of the present application detects the pressure value in the reaction chamber 10 through the pressure transmitter 430, and uses the first vacuum valve 520 and the pressure transmitter 430 to adjust the pressure so that the pressure in the reaction chamber 10 is within a 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 with 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 with powder, such as a space environment with silicate minerals and iron oxides.

[0089] The input / output assembly 30 is connected to the reaction chamber and the vacuum chamber through a pipeline, and the pipeline is connected to the reaction chamber and the vacuum chamber in a weldable manner, but is certainly not limited to the welding manner.

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

[0091] In an optional embodiment, the input-output component 30 also 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 in the vacuum chamber 20 and connected to the reaction chamber 10. The two vacuum electrodes 360 are used to provide a strong electric field, and through the input of high-voltage DC or AC power signals, to simulate space environments such as gas corona discharge, droplet breakage, and particle movement under a strong electric field.

[0092] The above test device 100 can improve the reliability of the actual use of the spacecraft by conducting material tests in advance, and reduce the risk of material damage and adverse reactions that cause the space environment to cause failure to work.

Various modifications and changes may be made on the basis of the above embodiments without departing from the scope of the present disclosure. Similarly, the various technical features of the above embodiments may be arbitrarily combined to form other embodiments of the present application that may not be explicitly described.
