Automatic planktonic algae sample injector

Abstract

The invention discloses an automatic planktonic algae sample injector. The automatic planktonic algae sample injector comprises a control device, an execution device and PC upper computer software, wherein the control device is electrically connected with the PC upper computer software and the execution device; the execution device comprises a peristaltic pump, a sampling mechanism, a cleaning cup, a guide rail sliding block, a horizontal movement module and a vertical movement module; and the sampling mechanism comprises a sampling frame, a sampling needle module and a sampling needle clampedon the sampling needle module. According to the invention, the peristaltic pump is used for continuous liquid flow sampling, so that the sampling operation is simplified, and the time and space costsare optimized; the sample container is placed in the system shell, so that the sample is prevented from being polluted by the outside, and the observation accuracy is improved; through multi-channelsimultaneous sampling, the sampling time is saved, and free selection and observation of multiple groups of samples are realized; and algae precipitation and aggregation are avoided through shaking ofthe sampling frame, and the problems that the observation precision is influenced and a pipeline is possibly blocked are avoided.

Description

technical field [0001] The invention relates to the technical field of automatic sampling, in particular to an automatic sampler for planktonic algae. Background technique [0002] The identification and counting of phytoplankton in water body is of great significance to the analysis, evaluation and protection of water environment. At present, microscopic observation of planktonic algae samples is an important means for algae research and monitoring personnel to identify and count algae. In the process of sample preparation and algae identification and counting, it takes a lot of time and energy for algae researchers, which reduces the efficiency of algae detection and popularization. . Therefore, as an important part of the automatic monitoring method for planktonic algae, it is of great significance to realize the automatic sampling of planktonic algae samples. [0003] At present, the sampling method of planktonic algae samples on the market is mainly the automatic load...

AI Technical Summary

Problems solved by technology

[0003] At present, the sampling method of planktonic algae samples on the market is mainly the automatic loading machine in the form of loading glass slides. It still needs to manually make a large number of glass slides and manually place them on the equipment, which is time-consuming and labor-intensive and has a lot to do with the operating habits of different people. , it is difficult to meet the standardization and high-throughput requirements of subsequent automatic detection and identification of algae

As far as the automatic sampling function is concerned, the autosamplers produced by most existing manufacturers are either not suitable for microscopic observation of planktonic algae, or the sample container is exposed to be easily polluted, the sampling channel is single, and the planktonic algae sample cannot be collected quickly. Static, easy to condense into agglomerates, etc., will not only cause blockage of the sampling pipeline, but also affect the detection accuracy
