[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] like Figure 1 As shown, an in-situ detection device for volatile components in planetary soil according to certain embodiments of this application includes: a detection component 300 and a protective component 100. The detection component 300 includes a detection heating element 310 and a detection collection box 320 (see...). Figure 2 ); The detection heating element 310 is a laser, the protective assembly 100 includes an air intake shroud 130, and the detection collection box 320 is a box with one open end. The air intake shroud 130 is fixedly connected to the open end of the detection collection box 320 (see details). Figure 3 A closed detection and collection chamber structure is formed within the detection and collection box 320 to collect volatile components of planetary soil. A first air inlet 136 is provided at the bottom of the air inlet shroud 130 (see details). Figure 4 The detection and collection box 320 has a window 321 on its end wall (see details). Figure 5 The window 321 and the first air inlet 136 are located in the optical path of the laser beam emitted by the laser of the detection heating element 310, so as to ensure that the laser beam emitted by the laser of the detection heating element 310 can irradiate the planetary soil through the window and the first air inlet 136, heat the planetary soil, and cause the volatile components in the planetary soil to turn into gas, enter the detection collection box 320, and be detected.

Each set of component detection optical path assemblies includes a light source mechanism 330, a detection mechanism 340, and a plurality of reflectors 323. The reflectors 323 are disposed on the inner wall of the detection and collection box 320 (see details). Figure 6 The light source mechanism 330 is used to emit detection light, and the light source mechanism 330 can be tuned to emit lasers of different wavelengths to adapt to the characteristic absorption lines of different gases. The detection light is reflected by several of the reflectors 323 in the detection collection box 320 and enters the detection mechanism 340 to form the composition detection light path C; Among them, several reflectors 323 extend the optical path of the detection light within the detection collection box 320, that is, extend the optical path of the component detection optical path C, so as to facilitate the absorption of volatile component gases entering the detection collection box 320. Different gas molecules have characteristic absorption of light of different wavelengths. The wider the range of laser wavelength coverage and the more it can measure the absorption spectrum of different gases, the more types of gases can be detected. At the same time, increasing the absorption optical path can enhance the absorption signal, thereby improving the detection sensitivity.

[0024] The detection assembly 300 consists of the detection heating element 310, the detection collection box 320, and several component detection optical path assemblies.

[0025] In some embodiments of this application, the detection collection box 320 is configured as a polygonal prism or cylinder, which facilitates the installation of a plurality of reflectors 323 on the inner sidewall of the polygonal prism to extend the optical path of the component detection optical path. For example, such as Figure 7 As shown, the detection collection box 320 is cylindrical, and the number of components detection optical path components is two.

The first mounting base 334 and the first pressure ring 332 cooperate with each other to fix the first heat sink 333. The detection light source 335 is mounted on one end of the second mounting base 336, and the first collimating lens 338 is mounted on the other end of the second mounting base 336. A second pressure ring 337 is provided on the first collimating lens 338. The second pressure ring 337 cooperates with the second mounting base 336 to fix the first collimating lens 338. A three-dimensional schematic diagram of the assembled light source mechanism 330 is shown below. Figure 10 As shown.

[0028] like Figure 11 As shown, in some embodiments of this application, the detection mechanism 340 includes a detection cylinder 341. According to the order from the outside to the inside of the detection collection box 320, a second heat sink 344, a first detector 345, and a second detector 349 are fixedly disposed in the detection cylinder 341 in sequence.

[0029] In some embodiments of this application, according to the outside to the inside order of the detection collection box 320, the detection tube 341 is provided with a third mounting base 343 and a fourth mounting base 347 in sequence, and a second spacer 346 is provided between the third mounting base 343 and the fourth mounting base 347; The second heat sink 344 is mounted on the third mounting base 343, and a third pressure ring 342 is provided on the second heat sink 344. The third mounting base 343 and the third pressure ring 342 cooperate with each other to fix the second heat sink 344. The first detector 345 is mounted on one end of the fourth mounting base 3437, and the second detector 349 is mounted on the other end of the fourth mounting base 347. A fourth pressure ring 348 is provided on the second detector 349. The fourth pressure ring 348 cooperates with the fourth mounting base 347 to fix the second detector 349. The three-dimensional view of the assembled detector collection box 320 is shown below. Figure 12 As shown.

[0030] like Figure 13 As shown in some embodiments of this application, the protective component 100 of the in-situ detection device for volatile components in planetary soil further includes a mounting box 120. The mounting box 120 is an open box at one end, covering the outer periphery of the detection and collection box 320. A groove is provided at the contact point between the mounting box 120 and the window 321, and a focusing lens 121 is installed within the groove (see details). Figure 5The focusing lens 121 is used to focus the laser emitted by the laser of the detection heating element 310; The air intake shroud 130 is fixedly connected to the open end of the mounting box 120; The top wall of the mounting box 120 is also provided with a fixing column, which is used to fix the detection heating element 310.

[0031] In some embodiments of this application, a fifth pressure ring 122 is further provided in the groove, and the fifth pressure ring 122 presses on the focusing lens 121, so that the focusing lens 121 is fixed in the groove.

[0032] like Figure 4 As shown, in some embodiments of this application, the air intake shroud 130 includes a first mounting portion 131, a second mounting portion 133, a third mounting portion 134 connected to the second mounting portion 133, and a fourth mounting portion 135 connected to the third mounting portion 134. The first mounting portion 131 and the second mounting portion 133 are connected by a first connecting portion 132.

[0033] In some embodiments of this application, the first air inlet 136 is disposed on the fourth mounting portion 135. The diameter of the first air inlet 136 exhibits a variation pattern of decreasing from a first preset value to a fixed value, and then increasing from the fixed value back to the first preset value. The purpose of setting the diameter of the first air inlet 136 in this way is to facilitate the entry of volatile components into the detection and collection box 320 and their rapid diffusion within the detection and collection box 320.

[0034] In some embodiments of this application, the first mounting part 131 is fixedly connected to the open end of the mounting box 120, and the second mounting part 133 is fixedly connected to the bottom wall of the detection and collection box 320, as detailed below. Figure 3 This double-fixed connection facilitates the precise entry of volatile gas components into the detection and collection box 320, preventing them from entering the space between the installation box 120 and the detection and collection box 320.

[0035] In some embodiments of this application, the third mounting portion 134 is provided with a second air inlet 137, which is arranged around the first air inlet 136 to further and quickly collect the volatile components of the gas.

[0036] In some embodiments of this application, the diameter of the second air inlet 137 is smaller than the diameter of the first air inlet 136, which makes it easier for the gas to enter to be less likely to be discharged and to be more easily enriched.

[0037] In some embodiments of this application, the axis of the second air inlet 137 is set at an angle to the axis of the first air inlet 136, which makes it easier to accumulate gas.

[0038] In some embodiments of this application, a sealing ring 322 is provided at the contact point between the second mounting part 133 and the bottom wall of the detection and collection box 320 to further prevent the escape of gas inside the detection and collection box 320 and to prevent gas from entering the space between the mounting box 120 and the detection and collection box 320.

[0039] In some embodiments of this application, the first connecting part 132 is provided with a plurality of heating elements 250. In order to ensure that the detection component 300 is at an appropriate temperature, the heating elements 250 are activated before the detection heating element 310 emits a laser to heat the detection component 300 to an appropriate temperature.

[0040] In some embodiments of this application, the protective component 100 further includes a protective cover 110, which is connected to the top wall of the mounting box 120 and covers the outer periphery of the detection heating element 310.

[0041] In some embodiments of this application, the in-situ detection device for volatile components in planetary soil further includes a control component 200, which is electrically and signal-connected to the detection heating element 310, the light source mechanism 330, and the detection mechanism 340, respectively, to provide power to the detection heating element 310, the light source mechanism 330, and the detection mechanism 340, and to control the detection heating element 310, the light source mechanism 330, and the detection mechanism 340.

[0042] like Figure 14 As shown, the control component 200 includes a power supply plug 210, a control connector 220, a power control board 230, and a spectrum control board 240. The power supply plug 210 is connected to the power control board 230, the detection heating element 310, the light source mechanism 330, the detection mechanism 340, and the heating element 250 respectively via cable 260, so that the power control board 230 can provide power to the detection heating element 310, the light source mechanism 330, the detection mechanism 340, and the heating element 250. The control connector 220 is connected to the detection heating element 310, the light source mechanism 330, and the spectral control board 240 via cables 260, respectively, so that the spectral control board 240 can control the optical signals of the detection heating element 310 and the light source mechanism 330 (see details). Figure 15 ).

[0043] A method for in-situ detection of volatile components in planetary soils according to certain embodiments of this application, implemented based on the aforementioned in-situ detection device for volatile components in planetary soils, includes: Place the first air inlet 136 of the in-situ detection device above the soil; Start the detection heating element 310, the light source mechanism 330 and the detection mechanism 340; The laser emitted by the probe heating element 310 heats the planetary soil, causing volatile components in the planetary soil to escape and be collected by the probe collection box 320; The detection light source 335 emitted by the light source mechanism 330 is absorbed by the volatile component gas collected in the detection collection box 320 and then detected by the detection mechanism 340 to obtain the photoelectric signal absorbed by the volatile component gas. Information on the volatile components of planetary soil can be obtained by analyzing the photoelectric signals absorbed by the volatile gases.

[0044] like Figure 16 As shown in some embodiments of this application, the in-situ detection method for volatile components in planetary soil includes: The in-situ detection device is mounted on the robotic arm of the Mars rover 400 via four mounting corners on the protective cover 110. When the Mars rover 400 reaches the location that needs to be explored, the Mars rover 400 robotic arm places the in-situ exploration device on the surface of the Martian soil. The Mars rover 400 sends a detection command to the in-situ detection device via an external control connector 220 located in the control component 200. First, the heating element 250 starts heating to heat the detection component 300 to the detection temperature. Then, the detection heating element 310, the light source mechanism 330, and the detection mechanism are turned on in sequence. The detection heating element 310 installed in the in-situ detection device receives the command and emits a laser. The emitted laser is focused into a heat source with high energy density after passing through the focusing lens 121. After passing through the focusing lens 121 and window 321, the laser enters the probe collection box 320, passes through the first air intake 136 on the air intake shroud 130, and then strikes the Martian soil surface (see details). Figure 17 ); Because the laser, after being focused, becomes a heat source with high energy density, this heat source heats the Martian soil surface, causing the Martian soil to release volatiles. The volatile components that have escaped enter the detection and collection box 320 through the first air inlet 136 and the second air inlet 137 on the air inlet shroud 130; The volatile matter absorption light source mechanism 330 inside the detector collection box 320 emits laser light of a specific wavelength. Since different components have different absorption rates for laser light of a specific wavelength, the absorption rate of the specific wavelength is measured by the set detector mechanism, and the composition of the volatile components can be obtained, thereby obtaining the composition of Martian soil.

[0045] Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
