Embodiment
Below in conjunction with drawings and Examples, the utility model is done further detailed description.
Embodiment 1:
To shown in Figure 5, a kind of adjustable measurement mechanism of light path of measuring comprises flow cell 1, rotational structure 3, detent mechanism 4, directed part 22,23 and pedestal 5 as Fig. 1.
Described pedestal 5 is a hollow, and top has measures passage 51.
Described flow cell 1 is installed on the described pedestal 5, is a length and wide different rectangular parallelepiped, and length is 5mm, and wide is 2mm, both ends open, and an end is import, the other end is outlet.Described flow cell 1 is installed in the cylindrical jacket 2, keeps sealing between described flow cell 1 and the overcoat 2.Described overcoat 2 is provided with four holes 21, and the 90 degree ground that are separated by, described four holes 21 are distributed on the excircle of overcoat 2, make the light beams that pass in the hole 21 vertically pass described flow cell 1, thus make described flow cell 1 length and wide be respectively the measurement light path.Directed part 22,23 (present embodiment use bearing) is installed at the two ends of described overcoat 2 respectively, is used for making when 1 rotation of described flow cell passing the light beam of measuring passage 51 rotation axis and the height perpendicular to flow cell 1.When described flow cell 1 revolves when turning 90 degrees, measuring beam has guaranteed the length and the wide measurement light path that is respectively of described flow cell 1 still perpendicular to the wall of described flow cell 1.
Described rotating mechanism 3 is mounted in the rotation hand wheel on the overcoat 2, and rotation hand wheel 3 is provided with the groove that increases friction force, is convenient to rotate by hand.Described detent mechanism 4 comprises groove 41, the locating device that is arranged on described overcoat 2 bottoms; Described groove 41 is distributed on the excircle of described overcoat 2 with being 90 degree, and described locating device is installed in the described pedestal 5, comprises that an end has the spring 43 of steel ball 42.
The working method of the measuring cell that above-mentioned measurement light path is adjustable is as follows: when measuring the water sample of low concentration, as shown in Figure 8, measuring beam passes flow cell 1 perpendicular to the wall of described flow cell 1, the length that makes described flow cell 1 is for measuring light path, thereby make tested low concentration water sample enough absorptions be arranged, guaranteed measuring accuracy measuring light.Detected water sample flows to described flow cell 1 from the import of described flow cell 1, and flows out from outlet, has guaranteed real-time online measuring.When needs are measured the water sample of high concentration, rotate handwheel 3 by hand, the steel ball 42 that is stuck in the groove 41 leaves groove 41, and when rotating to another groove 41, steel ball 42 snaps in the groove again, thereby fixing described flow cell 1, pass the light beam of measuring passage 51 and pass flow cell 1, make the wide of described flow cell 1 for measuring light path, as shown in Figure 9 perpendicular to the wall of described flow cell 1, thereby the light that sees through tested high concentration water sample can better be received, guaranteed measuring accuracy.Because the groove 41 on the described overcoat 2 is to be distributed on the excircle of overcoat 2 with being separated by 90 degree, therefore described flow cell 1 turns over 90 degree when rotating at every turn, and then makes the length and the wide measurement light path that is respectively of described flow cell 1.
