Description

Technical Field

[0001] This utility model relates to the field of infrared spectroscopy detection technology, specifically to an infrared spectroscopy detection experimental device. Background Technology

[0002] Infrared spectroscopy is an analytical technique based on the absorption characteristics of substances to infrared light. It is used to study molecular structure and chemical composition. Infrared spectroscopy utilizes the absorption characteristics of substances to infrared light of different wavelengths to induce vibrational energy level transitions in molecules. The wavelength of infrared light absorbed by chemical bond vibrations depends on their dynamic constant and atomic mass. Therefore, different chemical bonds or functional groups will produce characteristic absorption peaks in specific wavenumber regions, thus reflecting information about molecular structure.

[0003] Existing patent CN202420510219.5 discloses an infrared spectroscopy detection test device, including a base frame, a side plate fixedly installed on one side of the top of the base frame, a sliding groove opened on one side of the side plate, a cover plate and a tray slidably installed in the sliding groove, a clamping mechanism installed on one side of the side plate, and a detection cylinder installed in the clamping mechanism;

[0004] In the actual implementation of the aforementioned patent, the height of the infrared probe is adjusted to adapt to the detection of items of different volumes. However, simply adjusting the height of the infrared probe results in incomplete detection of the material being tested. Therefore, we propose an infrared spectroscopy detection experimental device. Utility Model Content

[0005] The purpose of this invention is to provide an infrared spectroscopy detection and testing device that solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an infrared spectroscopy detection test device, including a base, a detection cylinder fixed on the top of the base, and a detection component connected to the top of the detection cylinder;

[0007] The detection assembly includes a cover plate that fits against the top of the detection cylinder. A rotating shaft extends through the top of the cover plate, and a fixing plate is fixedly connected to the tail end of the rotating shaft. Three evenly distributed infrared probes are fixed to the bottom of the fixing plate. A horizontal plate is provided on the upper side of the rotating shaft, and a servo motor is fixedly installed on the top of the horizontal plate. The drive shaft of the servo motor passes through the horizontal plate and is fixedly connected to the rotating shaft. A lifting assembly is connected to the outer end of the horizontal plate.

[0008] By adopting the above technical solution, the item to be tested is placed at the bottom of the inner cavity of the testing cylinder. Then, the lifting assembly is used to lift the horizontal plate, thereby adjusting the height of the rotating shaft and infrared probes relative to the item to be tested. Then, the servo motor is started to drive the rotating shaft to rotate, thereby driving multiple infrared probes to rotate. This helps to improve the comprehensiveness of the infrared probes in detecting the item, and thus helps to improve the testing results.

[0009] In a preferred embodiment of this utility model, the lifting assembly includes a vertical plate, which is fixed to one side of the top of the base. A sliding cavity is formed on the inner side wall of the vertical plate. A lead screw motor is fixedly installed at the bottom of the sliding cavity. A lead screw is fixedly connected to the outer end of the drive shaft of the lead screw motor. The outer end of the lead screw is rotatably connected to the top of the sliding cavity. A suitable lead screw slider is fitted on the outer wall of the lead screw. The outer wall of the lead screw slider is fixedly connected to the horizontal plate.

[0010] By adopting the above technical solution, in actual use, the lead screw motor can drive the lead screw to rotate, thereby driving the lead screw slider to rise and fall, thus driving the horizontal plate to rise and fall, and indirectly driving the infrared probe to rise and fall.

[0011] In a preferred embodiment of this utility model, an electric push rod is fixedly installed on the other side of the top of the base, and a connecting plate is fixedly connected to the outer end of the push rod. The outer end of the connecting plate is fixedly connected to the cover plate.

[0012] By adopting the above technical solution, the cover plate can be raised and lowered by the electric push rod, which facilitates the separation of the cover plate and the detection cylinder, thus making it convenient to pick up and put down the detection items.

[0013] In a preferred embodiment of this utility model, a suitable rubber pad is fixedly glued to the bottom of the cover plate.

[0014] In a preferred embodiment of this utility model, an air inlet pipe is connected through the lower side of one side wall of the detection cylinder, an air outlet pipe is fixedly connected to the top of the cover plate, an annular pipe is fixedly installed at the bottom of the inner cavity of the detection cylinder, and a plurality of evenly distributed short air outlet pipes are fixedly connected to the inner wall of the annular pipe, with the inner end of the air inlet pipe connected to the annular pipe.

[0015] By adopting the above technical solution, gas is introduced into the lower side of the inner cavity of the detection cylinder, and the gas is evenly distributed in the lower side of the inner cavity of the detection cylinder using an annular tube and multiple short gas outlet tubes, with the gas outlet tubes on the upper side. This allows the gas to move from bottom to top, thereby driving out carbon dioxide inside the detection cylinder more thoroughly, which is beneficial to the accuracy of the detection test.

[0016] In a preferred embodiment of this utility model, rubber sheets are fixed at the four corners of the bottom of the base.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] The infrared spectroscopy detection test device of this application can adjust the height of the detection component by adjusting the component, and at the same time adjust the distance between the infrared probe and the object to be detected. Multiple infrared probes are set up, and a servo motor drives the rotating shaft to rotate, so that multiple infrared probes rotate during the detection process, thereby improving the comprehensiveness of the detection.

[0019] By introducing gas into the lower part of the inner cavity of the detection cylinder and distributing the gas evenly on the lower part of the inner cavity using an annular tube and multiple short gas outlet tubes, with the gas outlet tubes on the upper side, the gas moves from bottom to top, thus more thoroughly expelling the carbon dioxide inside the detection cylinder, which is beneficial to the accuracy of the detection test.

[0027] Please see Figure 1-3 The present invention provides a technical solution: an infrared spectroscopy detection test device, including a base 1, a detection cylinder 11 fixed on the top of the base 1, and a detection component connected to the top of the detection cylinder 11;

[0028] The detection assembly includes a cover plate 12, which is attached to the top of the detection cylinder 11. A rotating shaft 26 is movably passed through the top of the cover plate 12. A fixing plate 27 is fixedly connected to the tail end of the rotating shaft 26. Three evenly distributed infrared probes 28 are fixed to the bottom of the fixing plate 27. A horizontal plate 24 is provided on the upper side of the rotating shaft 26. A servo motor 25 is fixedly installed on the top of the horizontal plate 24. The drive shaft of the servo motor 25 passes through the horizontal plate 24 and is fixedly connected to the rotating shaft 26. A lifting assembly is connected to the outer end of the horizontal plate 24.

[0029] It should be understood that in actual use, the item to be tested is placed at the bottom of the inner cavity of the testing cylinder 11, and then the lifting assembly is used to drive the horizontal plate 24 to rise and fall, thereby driving the rotating shaft 26 and the infrared probe 28 to adjust the height of the item to be tested. Then, the servo motor 25 is started to drive the rotating shaft 26 to rotate, thereby driving multiple infrared probes 28 to rotate, which helps to improve the comprehensiveness of the infrared probes 28 in detecting the item to be tested, and thus helps to improve the testing effect.

[0030] Furthermore, rubber sheets are fixed at the four corners of the bottom of the base 1, which makes the device highly slip-resistant when placed and used.

[0031] like Figure 1 As shown; the lifting assembly includes a vertical plate 2, which is fixed to one side of the top of the base 1. A sliding cavity is provided on the inner side wall of the vertical plate 2. A lead screw motor 21 is fixedly installed at the bottom of the sliding cavity. A lead screw 22 is fixedly connected to the outer end of the drive shaft of the lead screw motor 21. The outer end of the lead screw 22 is rotatably connected to the top of the sliding cavity. A suitable lead screw slider 23 is fitted on the outer wall of the lead screw 22. The outer wall of the lead screw slider 23 is fixedly connected to the horizontal plate 24.

[0032] It should be understood that in actual use, the lead screw motor 21 can drive the lead screw 22 to rotate, thereby driving the lead screw slider 23 to rise and fall, thereby driving the horizontal plate 24 to rise and fall, and indirectly driving the infrared probe 28 to rise and fall.

[0033] like Figure 1 As shown; an electric actuator 13 is fixedly installed on the other side of the top of the base 1, and a connecting plate 14 is fixedly connected to the outer end of the actuator 13. The outer end of the connecting plate 14 is fixedly connected to the cover plate 12.

[0034] It should be understood that the electric push rod 13 can drive the cover plate 12 to rise and fall, thereby facilitating the separation of the cover plate 12 and the detection cylinder 11, and making it convenient to pick up and put down the detection items.

[0035] Furthermore, a suitable rubber pad is glued to the bottom of the cover plate 12. The rubber pad improves the sealing performance when the cover plate 12 is pressed against the detection cylinder 11, which helps to prevent the intrusion of external gas.

[0036] like Figure 1 and 3 As shown; an air inlet pipe 15 is connected through the lower side of one side wall of the detection cylinder 11, an air outlet pipe 16 is fixedly connected to the top of the cover plate 12, an annular pipe 17 is fixedly installed at the bottom of the inner cavity of the detection cylinder 11, and multiple evenly distributed short air outlet pipes 18 are fixedly connected to the inner wall of the annular pipe 17. The inner end of the air inlet pipe 15 is connected to the annular pipe 17.

[0037] It should be understood that by introducing gas into the lower side of the inner cavity of the detection cylinder 11, and by using the annular tube 17 and multiple short gas outlet tubes 18 to distribute the gas evenly on the lower side of the inner cavity of the detection cylinder 11, with the gas outlet tube 16 on the upper side, the gas moves from bottom to top, thereby driving out the carbon dioxide inside the detection cylinder 11 more thoroughly, which is beneficial to the accuracy of the detection test.
