Abstract

The invention relates to a device for acquiring variation of quantity of planktonic animal, in particular to a sample detecting circulating water device with planktonic animal optical counting function. The sample detecting circulating water device comprises a lower layer power device, a middle layer sample detecting device and a sample injector; wherein the lower layer power device comprises a water tank and a submersible pump; the middle layer sample detecting device comprises a flow meter and an optical planktonic animal counter, the water tank is communicated with the submersible pump, the output terminal of the submersible pump is communicated with one end of the flow meter, the other end of the flow meter is communicated with the water inlet of the sample injector, the water outlet of the sample injector is communicated with the inlet of the optical planktonic animal counter, the outlet of the optical planktonic animal counter is communicated with the water tank; an upper water channel control valve is arranged on the organic glass pipeline between the submersible pump and the flow meter, and a lower water channel control valve is arranged on the organic glass pipeline between the optical planktonic animal counter and the water tank. The device of the invention solves the problems of vibration interference, bubble production in sample injection, manual control of flow, mixing of sample and rapid circulation stabilization as well as recovery loss reduction by adjusting flow rate and water level reasonably and combining appropriate sample injection amount and sample injection frequency.

Description

technical field [0001] The invention relates to a device for obtaining changes in the number of plankton, in particular to a sample-measuring circulating water device for optical counting of plankton. Background technique [0002] Plankton optical counter OPC has been widely used as an effective tool to quickly obtain plankton quantity changes and size distribution, field surveys and laboratory research. Photoelectric conversion, the plankton particles in the water body trigger the induction circuit to generate electrical pulses, and the information including particle size and quantity is formed and recorded. [0003] However, in the use of OPC, it will encounter practical problems such as detecting water flow, flow velocity is difficult to control, water impurities and particles are mixed, which greatly reduces the counting accuracy. At present, in the application of indoor plankton optical counters, the main problems are that it is not easy to obtain a stable counting and...
