Description

Technical Field

[0001] The utility model relates to the technical field of near-infrared spectrometers, in particular to an integrated liquid off-line detection near-infrared spectrometer. Background Art

[0002] At present, the near-infrared spectrometer is an important rapid detection device in the industrial production process. However, one of the biggest technical problems faced by the known hand-held near-infrared spectrometers is that the changes in the observation angle, observation distance, and ambient light of the spectrometer during the measurement process will cause large measurement errors. Therefore, some near-infrared spectrometers for positioning samples have emerged. Especially for the detection of liquids, the liquid needs to be placed in a liquid cell, and the liquid in the liquid cell is detected by an infrared detection probe. At present, there is no good device to realize this off-line detection function. Summary of the Utility Model

[0003] The utility model aims at the deficiencies of the prior art and provides an integrated liquid off-line detection near-infrared spectrometer.

[0004] The utility model is realized by the following technical solutions. An integrated liquid off-line detection near-infrared spectrometer is provided, which includes an installation box and an installation base located inside the installation box. The installation box includes a bottom plate and an upper cover bolted to the bottom plate. The installation base is bolted to the bottom plate. A vertical liquid cell insertion hole is opened on the upper end surface of the installation base, and a horizontally penetrating infrared probe installation hole is opened on the side surface of the installation base. The infrared probe installation hole passes through the liquid cell insertion hole. An operation hole is opened on the upper cover above the liquid cell insertion hole, and an openable cover plate is installed on the operation hole.

[0005] When this solution is used, the openable cover plate of the upper cover is opened, and the liquid cell is vertically inserted into the liquid cell insertion hole. The transmitting end and the receiving end of the infrared detection probe are respectively located on both sides of the liquid cell to detect the sample inside.

[0006] As an optimization, the openable cover plate is hinged to the upper cover, so as to realize the opening and closing of the openable cover plate.

[0007] As an optimization, the bolt through holes on the installation base are long holes and the extending direction is parallel to the infrared probe installation hole. Thus, the position of the installation base can be adjusted, and the distance between the transmitting end and the receiving end of the infrared detection probe can be adjusted.

[0008] As an optimization, the installation base includes a lower installation block bolted to the bottom plate and an upper installation block bolted to the lower installation block. The liquid cell insertion hole extends downward from the upper end surface of the upper installation block into the lower installation block. The installation base is formed by the lower installation block and the upper installation block.

[0009] As an optimization, the lower end face of the upper mounting block is provided with an upper arc surface, and the end face of the lower mounting block is provided with a lower arc surface. The upper arc surface and the lower arc surface form the infrared probe mounting hole. By forming the infrared probe mounting hole with the upper arc surface and the lower arc surface, the transmitting end and the receiving end of the infrared detection probe can be clamped between the upper arc surface and the lower arc surface to ensure that its position remains unchanged.

[0010] As an optimization, the liquid cell insertion hole is a rectangular counterbore, and the infrared probe mounting hole is a circular through hole. The rectangular counterbore in this solution is used to insert a rectangular liquid cell, and the circular through hole is used to install a circular infrared detection probe.

[0011] As an optimization, the lower mounting block is strip-shaped and the length direction is parallel to the infrared probe mounting hole, and the upper mounting block is mounted at one end of the lower mounting block. Thus, it is convenient to mount the infrared detection probe at the other end of the lower mounting block.

[0012] The beneficial effects of the present utility model are as follows: An integrated liquid off-line detection near-infrared spectrometer of the present utility model is provided with an openable cover plate on the operation hole of the upper cover. After opening the openable cover plate, the liquid cell can be vertically inserted into the mounting base, and the infrared detection probe is installed in the infrared probe mounting hole, so that the liquid cell is located in the detection area, thus facilitating the replacement of the liquid cell and realizing rapid detection of the liquid cell. Moreover, the present utility model is convenient to carry, easy to use, and has high detection accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] To clearly illustrate the technical features of this solution, the following will elaborate on this solution through specific embodiments.

[0024] As Figures 1-8 shown, an integrated liquid off-line detection near-infrared spectrometer of the present utility model includes an installation box and an installation base located inside the installation box. The installation box is a rectangular closed box body, and various components are installed inside.

[0025] The installation box includes a bottom plate 1 and an upper cover 2 bolted to the bottom plate 1. The bottom plate 1 is a rectangular flat plate, with six through holes opened on its periphery. Six threaded holes are opened on the bottom surface of the edge of the upper cover 2. The bottom plate 1 and the upper cover 2 are connected by screws below the bottom plate 1.

[0026] The installation base is bolted to the bottom plate 1. A vertical liquid cell insertion hole 6 is opened on the upper end surface of the installation base, and a horizontally penetrating infrared probe mounting hole 7 is opened on the side surface of the installation base. The infrared probe mounting hole 7 penetrates through the liquid cell insertion hole 6. The liquid cell insertion hole 6 is a rectangular counterbore, and the infrared probe mounting hole 7 is a circular through hole.

[0027] Either the transmitting end or the receiving end of the infrared detection probe is installed on the installation base, and the other is installed on the bottom plate 1. The bolt through hole on the installation base is an elongated hole, and its extending direction is parallel to the infrared probe mounting hole 7. Therefore, by adjusting the position of the installation base, the distance between the transmitting end and the receiving end can be adjusted, thereby adjusting the detection accuracy.

[0028] The installation base includes a lower mounting block 4 bolted to the bottom plate 1 and an upper mounting block 5 bolted to the lower mounting block 4. The lower mounting block 4 is strip-shaped, and its length direction is parallel to the infrared probe mounting hole 7. The upper mounting block 5 is installed at one end of the lower mounting block 4. Either the transmitting end or the receiving end of the infrared detection probe is installed on the upper end surface at the other end of the lower mounting block 4. Thus, the transmitting end and the receiving end are respectively inserted into both ends of the infrared probe mounting hole 7.

[0029] Since the upper mounting block 5 is installed at one end of the lower mounting block 4, in this embodiment, a protrusion is provided on the lower mounting block 4. The horizontal plane shape of the protrusion is the same as that of the upper mounting block 5, and the upper mounting block 5 is connected to the protrusion by four bolts.

[0030] The liquid cell insertion hole 6 is located at the middle position of the upper mounting block 5. The liquid cell insertion hole 6 extends downward from the upper end face of the upper mounting block 5 into the lower mounting block 4, and a rectangular counterbore is formed in the lower mounting block 4, so that the lower end of the liquid cell is supported on the bottom surface of the counterbore.

[0031] The lower end face of the upper mounting block 5 is provided with an upper arc surface, and the end face of the lower mounting block 4 is provided with a lower arc surface. The upper arc surface and the lower arc surface form the infrared probe mounting hole 7. The central angles of the upper arc surface and the lower arc surface are both slightly less than 180 degrees, so that there is a certain gap between the upper mounting block 5 and the lower mounting block 4. After the infrared detection probe is inserted into the infrared probe mounting hole 7, the infrared detection probe is clamped by the upper arc surface and the lower arc surface.

[0032] An operation hole is formed in the upper cover 2 above the liquid cell insertion hole 6. The operation hole is a rectangular hole and has an area larger than that of the liquid cell insertion hole 6. The liquid cell is inserted downward into the liquid cell insertion hole 6 through the operation hole. A switchable cover plate 3 is installed on the operation hole. In this embodiment, the switchable cover plate 3 is hinged to the upper cover 2, so as to realize the opening and closing of the switchable cover plate 3.

[0033] The usage method of the present utility model:

[0034] After the near-infrared spectrometer is assembled, it can be carried for use. When in use, the switchable cover plate 3 of the upper cover 2 is opened, the liquid cell is vertically inserted into the liquid cell insertion hole 6, and the emitting end and the receiving end of the infrared detection probe are respectively located on both sides of the liquid cell to detect the sample inside.
