Description
Technical Field
[0001] The utility model relates to the technical field of on-line laser-induced breakdown spectroscopy analyzers, in particular to a high-precision on-line coal quality analyzer based on laser-induced breakdown spectroscopy. Background Art
[0002] A laser-induced breakdown spectrometer is a brand-new analytical means in the field of spectral analysis. Its basic principle is to use a high-energy laser light source to form a high-intensity laser spot (plasma) on the surface of the analyzed material, so that the sample is excited to emit light. These lights are then analyzed by a spectral system and a detection system. With the continuous development of technology, in order to facilitate on-site use, more and more customers choose handheld laser-induced breakdown spectrometers.
[0003] When the existing laser-induced breakdown spectrometer detects coal blocks, it cannot control the detection end, which easily causes dust to adhere to the detection end face of the analyzer, thereby blocking the light, and the overall detection accuracy needs to be improved. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a high-precision on-line coal quality analyzer based on laser-induced breakdown spectroscopy, which can control the shielding of the detection end during the detection interval, avoid dust adhering to the detection end face, and improve the detection accuracy.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A high-precision on-line coal quality analyzer based on laser-induced breakdown spectroscopy includes an analyzer main body. An installation groove is provided at the detection end of the analyzer main body. A protective cover is snap-fitted inside the installation groove. A detection hole is provided on the end face of the protective cover. Two fixing seats are fixedly connected to the inner wall of the protective cover. An inner baffle is rotatably installed between the two fixing seats. The inner baffle blocks one side of the detection hole. A second linkage bracket is fixedly connected to the back of the inner baffle. A first linkage bracket penetrates through the inside of the second linkage bracket. Two through holes are provided on the end face of the protective cover, and a top rod penetrates through the inside of the through hole. One ends of the two top rods are fixedly connected to both ends of the first linkage bracket.
[0007] By adopting the above technical solution, the inner baffle can be used to block the detection hole when not detecting, avoiding dust from entering the inside of the protective cover, and further avoiding dust from adhering to the detection end face of the analyzer main body, effectively improving the detection accuracy.
[0008] Furthermore, a torsion spring is sleeved outside the rotating connection between the fixing seat and the inner baffle. One end of the torsion spring is fixedly connected to the side surface of the fixing seat, and the other end of the torsion spring is fixedly connected to the inner wall of the inner baffle.
[0009] By adopting the above technical solution, the torsion spring can be used to automatically reset the inner baffle when the coal block is separated from the protective cover.
[0010] Furthermore, a slide groove is provided on the lower surface of the protective cover, and a toggle bar is slidably installed inside the slide groove.
[0011] By adopting the above technical solution, the dust wiping operation can be performed by toggling the toggle bar, which is convenient to operate.
[0012] Furthermore, a wiping sleeve is sleeved and installed on the outside of one end of the toggle bar, and a flexible cotton strip is arranged on the outer surface of one side of the wiping sleeve, and the flexible cotton strip is attached to the end surface of the analyzer body.
[0013] By adopting the above technical solution, the detection end surface of the analyzer body can be wiped with a flexible cotton strip.
[0014] Furthermore, the detection hole corresponds to the position of the laser emitting end of the analyzer body.
[0015] By adopting the above technical solution, it is ensured that the laser is effectively irradiated on the coal block.
[0016] Furthermore, one end of the push rod is configured as a ball head structure, and two push rods are symmetrically distributed at two sides of the detection hole.
[0017] By adopting the above technical solution, it is ensured that the top rod stably contacts the external coal blocks.
[0018] In summary, the beneficial technical effects of the utility model are:
[0019] 1. When the utility model is in use, the protective cover buckle can be installed inside the mounting groove, and then the coal block to be detected can be pressed against the end face of the protective cover. During the process of the coal block fitting the end face of the protective cover, the coal block presses one end of the push rod, and the push rod retracts into the inside of the protective cover. At this time, the push rod drives the first linkage bracket to move toward the inside of the protective cover. Since the first linkage bracket runs through the through groove of the second linkage bracket, the first linkage bracket can effectively drive the second linkage bracket and the inner baffle to flip. The flipped inner baffle no longer blocks the detection hole. At this time, it can ensure that the laser passes through the detection hole to analyze the coal block. After the analysis is completed, the coal block is removed. Under the action of the torsion spring, the inner baffle is reset and re-blocks the detection hole, thereby effectively preventing external dust from entering the inside of the protective cover, thereby preventing dust from covering the end face of the analyzer body. This structure can prevent dust from blocking the laser during long-term use, thereby ensuring high detection accuracy.
[0020] 2. During the use of the utility model, the toggle bar can be regularly toggled, and the toggle bar slides back and forth in the slide groove of the protective cover, so that the flexible cotton strip on the wiping sleeve can wipe the detection end surface of the analyzer body, further avoiding dust from adhering to the detection end surface of the analyzer body, so that the detection accuracy is further improved.

[0025] The method of the utility model is further described in detail below in conjunction with the accompanying drawings.

The rods 4 are symmetrically distributed at the two sides of the detection hole 10. When in use, the protective cover 3 can be snap-fitted into the inside of the mounting groove 2, and then the coal block to be detected is pressed against the end face of the protective cover 3. During the process of the coal block fitting the end face of the protective cover 3, the coal block presses one end of the push rod 4, and the push rod 4 retracts into the inside of the protective cover 3. At this time, the push rod 4 drives the first linkage bracket 7 to move toward the inside of the protective cover 3. Since the first linkage bracket 7 runs through the through groove of the second linkage bracket 8, the first linkage bracket 7 can effectively drive the second linkage bracket 8 and the inner baffle 9 to flip. The flipped inner baffle 9 no longer blocks the detection hole 10. At this time, it can ensure that the laser passes through the detection hole 10 to analyze the coal block. After the analysis is completed, the coal block is removed. Under the action of the torsion spring 12, the inner baffle 9 is reset and re-blocks the detection hole 10, thereby effectively preventing external dust from entering the inside of the protective cover 3, thereby preventing dust from covering the end face of the analyzer body 1. This structure can prevent dust from blocking the laser during long-term use, thereby ensuring high detection accuracy.
[0027] Reference Figure 2 A slide groove is provided on the lower surface of the protective cover 3, and a toggle strip 5 is slidably installed inside the slide groove. A wiping sleeve 6 is installed on the outside of one end of the toggle strip 5. A flexible cotton strip is provided on the outer surface of one side of the wiping sleeve 6. The flexible cotton strip is attached to the end surface of the analyzer body 1. During use, the toggle strip 5 can be regularly toggled, and the toggle strip 5 slides back and forth in the slide groove of the protective cover 3, so that the flexible cotton strip on the wiping sleeve 6 can wipe the detection end surface of the analyzer body 1, further avoiding dust from adhering to the detection end surface of the analyzer body 1, so that the detection accuracy is further improved.
[0028] Working principle: When in use, the protective cover 3 is snap-fitted into the inside of the mounting groove 2, and then the coal block to be detected is pressed against the end face of the protective cover 3. During the process of the coal block fitting the end face of the protective cover 3, the coal block presses one end of the push rod 4, and the push rod 4 retracts into the inside of the protective cover 3. At this time, the push rod 4 drives the first linkage bracket 7 to move toward the inside of the protective cover 3. Since the first linkage bracket 7 runs through the through groove of the second linkage bracket 8, the first linkage bracket 7 can effectively drive the second linkage bracket 8 and the inner baffle 9 to flip over. The flipped inner baffle 9 no longer blocks the detection hole 10, and the detection hole 10 can be ensured at this time. Light passes through the detection hole 10 to analyze the coal block. After the analysis is completed, the coal block is removed. Under the action of the torsion spring 12, the inner baffle 9 is reset and the detection hole 10 is re-covered, thereby effectively preventing external dust from entering the interior of the protective cover 3, thereby preventing dust from covering the end face of the analyzer body 1. At the same time, during use, the toggle bar 5 is regularly moved, and the toggle bar 5 slides back and forth in the slide groove of the protective cover 3, so that the flexible cotton strip on the wiping sleeve 6 can wipe the detection end face of the analyzer body 1, further preventing dust from adhering to the detection end face of the analyzer body 1.
