[0032] The features and exemplary embodiments of various aspects of the application will be described in detail below. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the application. However, it is obvious to those skilled in the art that the application can be implemented when some details in these specific details are not needed. The following description of the embodiments is only to provide a better understanding of the application by illustrating the example of the application.

[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The embodiments will be described in detail below in conjunction with the accompanying drawings.

[0034] Relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device that includes a series of elements includes not only those elements, but also other elements that are not explicitly listed, or also includes elements that are inherent to such process, method, article, or device. In the absence of further restrictions, the elements defined by the statement "comprising ..." do not exclude the presence of additional identical elements in the process, method, article, or device that includes the elements.

[0035] It should be understood that when describing the structure of a component, when a layer or a region is referred to as being "on" or "over" another layer or another region, it may mean that it is directly on the other layer or another region, or that other layers or regions are included between it and the other layer or another region. Moreover, if the component is turned over, the layer or a region will be "below" or "beneath" another layer or another region.

[0036] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0037] It should be understood that in the embodiment of the present application, "B corresponding to A" means that B is associated with A, and B can be determined according to A. However, it should also be understood that determining B according to A does not mean determining B only according to A, and B can also be determined according to A and / or other information.

[0038] The applicant found that when spectral detection of rock samples is required, geologists usually collect rock samples outdoors and then bring the rock samples back to the laboratory. In the laboratory, the samples are tested using short-wave infrared spectroscopy equipment, which often requires a long detection cycle, has low efficiency, and is likely to affect the timeliness of spectral detection, while also increasing the cost of spectral detection.

[0039] In view of the above analysis, the applicant has proposed a portable short-wave infrared spectrometer, including a detection mechanism and a holding mechanism. The probe assembly and the injection assembly are both installed in the main body. The injection assembly includes an injection nozzle and a connecting pipe that are connected in sequence, which can spray gas and / or liquid to clean the surface of the sample to be tested and the probe assembly, thereby improving the accuracy of spectral detection and directly obtaining high-quality spectral data; in addition to being used for spraying and / or liquid, the injection nozzle can cover the surface of the sample to be tested when performing spectral detection, reduce the impact of ambient light on spectral detection, and also improve the accuracy of spectral detection. In the process of using the portable short-wave infrared spectrometer of the embodiment of the present application, geologists can hold the holding mechanism in their hands and directly use the detection mechanism for detection at the collection site of the sample to be tested, such as rocks, which greatly improves the efficiency of spectral detection and reduces the detection cost.

[0040] Figure 1 A schematic diagram of the structure of a portable short-wave infrared spectrometer according to an embodiment of the present application. Figure 2 A schematic diagram of the structure of the probe assembly 12 and the injection assembly 13 of the portable short-wave infrared spectrometer according to an embodiment of the present application.

[0041] See also Figure 1 and Figure 2The present application provides a portable short-wave infrared spectrometer, comprising: a detection mechanism 1, comprising a main body 11, a probe assembly 12 and a spray assembly 13, the main body 11 extends along a first direction X, and the probe assembly 12 is arranged at one end of the main body 11 along the first direction X; the spray assembly 13 comprises a spray nozzle 131 and a connecting pipe 132 connected in sequence, the spray nozzle 131 is annular and extends along the first direction X, and the spray nozzle 131 at least partially surrounds the probe assembly 12; a holding mechanism 2, connected to the detection mechanism 1, the holding mechanism 2 extends along a second direction Y, and the first direction X and the second direction Y intersect; the holding mechanism 2 comprises a control assembly, and the detection mechanism 1 is communicatively connected to the control assembly.

[0042] In the portable short-wave infrared spectrometer of the embodiment of the present application, a geologist can hold the main detection part of the spectrometer, and other parts (such as the host 124, the light source, etc.) can be moved along with the geologist in a movable manner.

[0043] The main body 11 of the detection mechanism 1 extends along the first direction X and can accommodate other components of the detection mechanism 1. The holding mechanism is connected to the detection mechanism 1 and extends along the second direction Y, wherein the first direction X intersects with the second direction Y, so that the detection mechanism 1 and the holding mechanism 2 are connected to form a pistol-like shape. When the geologist holds the holding mechanism 2, the detection mechanism 1 is pressed against the surface of the sample to be tested, so that the geologist can perform spectral detection on the sample to be tested at the collection site of the sample to be tested.

[0044] The injection nozzle 131 of the injection assembly 13 is annular and surrounds the probe assembly 12. The injection nozzle 131 can spray liquid and / or gas, which can clean the dust, debris and other interferences on the surface of the sample to be tested, so as to improve the accuracy of spectral detection and directly obtain high-quality spectral data. The liquid and / or gas sprayed by the injection nozzle 131 is introduced into the injection nozzle 131 through the connecting pipe 132. It can be understood that an air pump or a liquid pump can be provided to pump the gas or liquid to the injection nozzle 131. Optionally, the injection assembly 13 is provided with an air pump and a liquid pump at the same time, that is, it has both the liquid spraying and the air jetting functions. The injection assembly 13 can selectively perform the liquid spraying and the air jetting actions according to the set program, and can also first spray the liquid to clean the mud, dust and the like on the surface of the sample to be tested, and then quickly blow dry the wetted surface of the sample to be tested by air jetting, thereby improving the test efficiency.

[0045] Considering that the jet nozzle 131 surrounds the probe assembly 12, when performing spectrum detection on the sample to be tested, the jet nozzle 131 abuts against the surface of the sample to be tested, and the jet nozzle 131 can shield the surrounding area of ​​the probe assembly 12 to reduce the interference of external ambient light on the spectrum detection, thereby further improving the accuracy of the spectrum detection. The overall shape of the detection mechanism 1 and the holding mechanism 2 after being connected is approximately a pistol.

[0046] In addition, the holding mechanism 2 is also provided with a control component for controlling the detection mechanism 1. Considering that the detection mechanism 1 and the holding mechanism 2 are connected in a shape similar to a pistol, the control component can be arranged at the connection between the detection mechanism 1 and the holding mechanism 2, similar to the trigger of the pistol. It can be understood that the control component can include multiple physical or virtual buttons to respectively control various components of the portable short-wave infrared spectrometer of the embodiment of the present application.

[0047] Further, see Figure 1 and Figure 2 The probe assembly 12 includes: a shell 121, which is cylindrical and extends along the first direction X, and the end of the shell 121 has a transparent lens; a light source assembly 122, which is arranged in the shell 121, and the light source assembly 122 includes an optical fiber, and the optical fiber passes through the shell 121 and the main body 11; a detection assembly 123, which is arranged in the shell 121, and the detection assembly 123 includes a transmission signal line, and the transmission signal line passes through the shell 121 and the main body 11.

[0048] The housing 121 has a certain sealing property, and is used to protect the light source assembly 122 and the detection assembly 123. The light source assembly 122 introduces short-wave infrared light through optical fiber, and the introduced short-wave infrared light is emitted through the transparent lens of the housing 121, irradiated on the tested surface of the tested sample, and after reflection and scattering, the detection assembly 123 receives the reflected and / or scattered light, and derives the collected light signal through the transmission signal line, so as to obtain the short-wave infrared spectrum of the tested sample according to the detected light. It can be understood that after using liquid jet to clean the surface of the tested sample, gas can be sprayed to sweep away the residual liquid on the tested surface of the tested sample and the surface of the transparent lens, so as to keep the tested surface of the tested sample and the surface of the transparent lens clean and reduce the error of spectral detection.

[0049] Figure 3 A schematic diagram of the principle of the light source component 122 and the detection component 123 of the portable short-wave infrared spectrometer according to an embodiment of the present application.

[0050] For further information, see Figure 3 The portable short-wave infrared spectrometer of the embodiment of the present application further includes: a host 124, electrically connected to the transmission signal line; and a short-wave infrared light source 125, connected to the optical fiber.

[0051] The short-wave infrared light source 125 is connected to the optical fiber, and the short-wave infrared light emitted by the short-wave infrared light source 125 is transmitted to the light source assembly 122 located in the housing 121 through the optical fiber. The light signal obtained by the detection assembly 123 is exported to the host 124 through the transmission signal line. After calculation and processing by the host 124, the short-wave infrared spectrum of the sample under test can be displayed in the form of data and / or images, as a basis for analyzing the composition and physical and chemical form of the sample under test. For example, the probe assembly 12 with a built-in short-wave infrared light source is a reflection probe, and the measurement result obtained is the relative reflectivity. The mineral composition of the rock can be obtained according to the relative reflectivity result. It can be understood that the host 124 and the light source can be installed in the movable detection vehicle 3, so that the host 124 and the light source can move with the geological personnel, so as to facilitate the spectral detection of the sample under test at the collection site of the sample under test.

[0052] Further, see Figure 3 The portable short-wave infrared spectrometer of the embodiment of the present application also includes a movable detection vehicle 3, and the control component and the detection component 123 are both electrically connected to the movable detection vehicle 3; the movable detection vehicle 3 is provided with multiple sets of support wheels and a traction unit. When using the portable short-wave infrared spectrometer of the embodiment of the present application, the geologist can move the movable detection vehicle 3 with the geologist at the collection site of the sample to be tested. When moving the movable detection vehicle 3, the traction unit can be used to drive the movable detection vehicle 3 to move.

[0053] Figure 4 Schematic diagram of the internal structure of the injection nozzle 131 of the portable short-wave infrared spectrometer according to an embodiment of the present application.

[0054] For further information, see Figure 4 , and combined with Figure 2 The injection nozzle 131 is in the shape of a truncated cone extending along the first direction X, and the diameter of the injection nozzle 131 gradually increases along the injection direction; the injection nozzle 131 includes a first end plate 141, which is located on the end surface of the injection nozzle 131 along the injection direction, and the first end plate 141 is provided with a plurality of first through holes arranged along the circumferential direction.

[0055] The injection nozzle 131 is truncated cone-shaped, and the diameter of the injection nozzle 131 gradually increases along the injection direction, so that the gas and / or liquid after injection tends to diffuse, so as to increase the cleaning area of ​​the surface of the sample to be tested. In addition, when performing spectral detection, the truncated cone-shaped injection nozzle 131 can also increase the area around the tested area, reducing the influence of the injection nozzle 131 on the short-wave infrared light. The gas and / or liquid is injected from the first through hole of the first end plate 141, which can reduce the possibility of backflow of rock cuttings and soil.

[0056] Further, see Figure 2 and Figure 4The injection nozzle 131 also includes: a second end plate 142, which is located on the side of the first end plate 141 opposite to the injection direction; the second end plate 142 is provided with a plurality of second through holes arranged along the circumferential direction; along the injection direction, the shape of the first through hole is the same as the shape of the second through hole; and a plurality of guide plates 143 are connected between the first end plate 141 and the second end plate 142.

[0057] The second end plate 142 is also provided with a plurality of second through holes, and the gas and / or liquid can flow from the second through holes to between the first end plate 141 and the second end plate 142, and then be ejected from the second through holes. Since the guide plate 143 is disposed between the first end plate 141 and the second end plate 142, the gas and / or liquid flow can be guided, so that the gas and / or liquid ejected from the first through holes is spiral, thereby improving the cleaning ability of the tested surface of the tested sample.

[0058] Further, see Figure 2 and Figure 4 One end of the guide plate 143 is hinged to the first end plate 141 , and the other end of the guide plate 143 is hinged to the second end plate 142 ; the second end plate 142 is rotatably arranged relative to the first end plate 141 , and the rotation axis is parallel to the first direction X.

[0059] When the second end plate 142 rotates relative to the first end plate 141, the guide plate 143 rotates together, so that the ejected gas and / or liquid can switch between positive spiral and reverse spiral, so that the liquid flow and / or air flow can reciprocate to sweep the surface of the sample to be tested, thereby further improving the cleaning ability of the surface of the sample to be tested.

[0060] Figure 5 Another schematic diagram of the internal structure of the injection nozzle 131 of the portable short-wave infrared spectrometer according to an embodiment of the present application.

[0061] For further information, see Figure 5 The injection assembly 13 also includes a driving assembly, which includes a motor 151, a ring gear 153, and an output gear 152. The output gear 152 is connected to the motor 151, and the ring gear 153 is sleeved on the outer edge of the second end plate 142. The ring gear 153 is power-connected to the output gear 152.

[0062] The driving assembly is used to drive the second end plate 142 to rotate. The electrode drives the output gear 152 to rotate, and the output gear 152 drives the rack to rotate. Since the rack is connected to the second end plate 142, the motor 151 can drive the second end plate 142 to rotate. It can be understood that the output gear 152 can directly mesh with the rack to drive the rack to rotate, or it can be indirectly connected to the rack power through a reduction gear set so that the rack rotates with an appropriate torque.

[0063] Figure 6A schematic diagram of the principle of the connecting tube 132 of the portable short-wave infrared spectrometer according to an embodiment of the present application.

[0064] For further information, see Figure 6 The connecting pipe 132 includes: a first sub-pipe 161, which is connected to the injection nozzle 131; the first sub-pipe 161 is provided with a first valve, and the control component controls the first valve to be opened or closed; a second sub-pipe 162, which is connected to the injection nozzle 131; the second sub-pipe 162 is provided with a second valve, and the control component controls the second valve to be opened or closed.

[0065] The gas can flow to the injection nozzle 131 through the first sub-tube 161, and the liquid can flow to the injection nozzle 131 through the second sub-tube 162. When the first valve is opened and the second valve is closed, only the gas flows to the injection nozzle 131, and the injection assembly 13 sprays the gas, which can perform preliminary cleaning on the sample to be tested; when the first valve is closed and the second valve is opened, only the liquid flows to the injection nozzle 131, and the injection assembly 13 sprays the liquid, which can further clean the sample to be tested; when the first valve is opened and the second valve is opened, the gas and the liquid flow to the injection nozzle 131, and after the two are mixed, they are sprayed from the injection assembly 13, which can further improve the cleaning ability. Of course, liquid spraying and air jetting can also be performed in sequence, first using liquid spraying to rinse the mud on the surface of the core that is difficult to blow off directly, and then jetting to dry it after liquid rinsing, so that the test results obtained on the dried core surface are more accurate.

[0066] Further, see Figure 6 The portable short-wave infrared spectrometer of the embodiment of the present application further includes: a jet source, including an air flow source 163 and a liquid flow source 164. The air flow source 163 can be in the form of an air pump, and is connected to the first sub-tube 161 to pass gas into the first sub-tube 161. The liquid flow source 164 can be in the form of a liquid pump, and is connected to the second sub-tube 162 to pass gas into the second sub-tube 162.

[0067] In summary, the embodiment of the present application provides a portable short-wave infrared spectrometer, including a detection mechanism and a holding mechanism. The probe assembly and the injection assembly are both installed in the main body. The injection assembly includes an injection nozzle and a connecting pipe that are connected in sequence, which can spray gas and / or liquid to clean the surface of the sample to be tested and the probe assembly, thereby improving the accuracy of spectral detection. In addition to being used for spraying and / or liquid, the injection nozzle can cover the surface of the sample to be tested when performing spectral detection, reduce the influence of ambient light on spectral detection, and also improve the accuracy of spectral detection. In the process of using the portable short-wave infrared spectrometer of the embodiment of the present application, the geologist can hold the holding mechanism in hand and directly use the detection mechanism to detect at the collection site of the sample to be tested, such as the rock outcropping in the field, the core obtained by drilling, etc., and directly obtain high-quality spectral data in the field, which greatly improves the efficiency of spectral detection and reduces the detection cost.

[0068] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto.
