Embodiment 1
[0027] Such as Figure 1-3 As shown, the portable water body pollutant enrichment device in the present embodiment comprises:
[0028] The lower shell 5 has a hollow cylindrical structure as a whole, and a notch 51 is opened on the outer peripheral surface;
[0029] Column clamp 9, which is connected to the inner wall of the lower shell 5; in this embodiment, the column clamp 9 includes: a column clamp mounting seat 91, which is connected to the inner wall of the lower shell 5; a fixing member 92, one end of which The column clamp mounting seat 92 is rotatably connected by a rotating member such as a pin shaft, and the opening and closing is realized by rotating the rotating member as an axis; One end is used to lock the fixing member 92 on the column clamp mounting seat 91;
[0030] An extraction column 8 (such as a C18 solid phase extraction column, etc.), which can be clamped and fixed in the lower shell 5 by the column holder 9; specifically, as Figure 4 As shown, the ...
Embodiment 2
[0047] The only difference between this embodiment and Embodiment 1 is that, as Figure 1-3 As shown, the enrichment device further includes: an upper cover limiter, which is used to prevent the upper cover 3 from being opened when the upper cover 3 closes the upper opening of the upper shell 1; specifically, the upper cover limiter The position member includes: a limit ring 18, which is connected to the outer peripheral surface of the upper cover 3; a limit seat 19, which is connected to the upper end surface of the second installation position 102; and a limit pin 17; the upper cover 3 is closed When the upper part of the upper shell 1 is opened, the position of the limit ring 18 corresponds to the position of the limit seat 19. If the limit ring 18 is located at the side of the limit seat 19, the limit pin 17 passes through the limit The ring 18 and the limit seat 19 are used to fix the position of the upper cover 3 and prevent the upper cover 3 from being opened; after the...
