Sample injection disc for water quality detection

Abstract

The invention discloses a sample introduction disc for water quality detection. The sample introduction disc comprises a base, an accommodating cavity, a stand column, a sample introduction disc body and a rotary driving mechanism, wherein a plurality of groups of positioning holes are formed in the sample introduction disc body and are uniformly distributed along the circumferential direction; a first sliding groove is formed in the side wall of each positioning hole, a clamping block is slidably mounted in the first sliding groove, the first end of the clamping block extends into the positioning hole from the side wall of each positioning hole, an elastic body is arranged between the clamping block and the sample introduction disc body, a second sliding groove is formed in the stand column, a sliding block is mounted in the second sliding groove, and a support body is hinged to the sliding block; a bracket body driving mechanism is arranged on the sliding block; a cleaning needle with a downward head part is arranged on the bracket body, and is positioned above the positioning holes; the stand column is further provided with a sliding block lifting driving mechanism. The sample introduction disc has the advantages that the stability is good, the sample bottle does not shake, collide or splash in practical application, the problems that the sample bottle is prone to colliding and cross contamination is prone to occurring are solved, and the sample introduction disc has the advantage of being safe and stable in work.

Description

technical field [0001] The invention relates to the field of sampling trays, in particular to a sampling tray for water quality testing. Background technique [0002] With the development of social economy and the improvement of people's living standards, the situation of environmental pollution is becoming increasingly severe, especially the problem of water pollution, so the equipment for environmental testing is very important. The existing continuous flow injector involves a sample injection link. During the sample injection process, the sample bottle needs to be placed in the sample injection tray, and then the next step of detection is performed. However, the existing sampling tray is prone to bumping when placing the sample bottle; the fixation of the sample bottle is not sufficient enough, and it is easy to spill, resulting in cross-contamination between samples; and the sampling tray is not easy to take and place during loading and unloading , After the water sampl...
