Description

Planktonic microorganism sampling device Technical Field The utility model relates to the technical field of plankton, in particular to a plankton sampling device. Background Plankton generally refers to a drift living in water without effective mobility, wherein the drift living in water is divided into phytoplankton and zooplankton, part of the plankton has swimming capability, but the swimming speed of the drift is usually slower than the flow rate of ocean current where the drift is positioned, so that the drift cannot effectively move in water, the plankton has no mobility in the living beings in water areas such as ocean, lake, river and the like, or the drift is very weak, so that the drift cannot move against water flow, and the drift floats on the water surface, and the living beings are always called plankton, and a sampling device is needed in the detection of the plankton. And just mention a plankton sampling device in the application file of publication number CN216473207U, during this use, through external controller control rotating motor, servo motor and suction pump, output through servo motor drives the screw rod and rotates, the screw rod drives the swivel joint and moves down through the effect of screw thread, the swivel joint drives the connecting rod and moves down, the connecting rod drives the sampling pipe and moves down, conveniently adjust the sampling height, the input through the suction pump produces suction after accomplishing, inhale the water through sampling pipe and bellows back, the output of suction pump sends the water into the inner chamber of a centrifuge tube, output through rotating motor drives the centrifuge tube through the mount pad and rotates, utilize the effect of centrifugal force to separate plankton and water, effectively improve sampling efficiency, through the cooperation use of above structure, it is inconvenient when using to have solved current sampling device, often need separate between water and the plankton by hand, and do not possess the function of adjusting the sampling height, reduce holistic practicality, thereby be inconvenient for people's problem of using, still have certain defect, need obtain optimizing, the concrete defect, when the centrifuge tube is separated through the centrifuge tube, the filter cartridge is cut down through the centrifugation, the centrifugation is convenient for obtaining the sample through the centrifugation volume, the centrifugation is only, the sample is concentrated and is concentrated to the water sample is obtained through the centrifugation volume of the centrifugation is not easy, and is convenient to be obtained simultaneously.
