The port at the connection end of the bottle is covered with a removable screen. The utility model has a simple structure, saves time and labor for the concentration of marine plankton, and ensures the accuracy of concentration of marine plankton samples.

Description

Marine Plankton Concentrator

technical field

The utility model belongs to the technical field of aquatic fishery scientific research, in particular to a marine plankton concentration device.

Background technique

At present, in the field of domestic aquatic fishery scientific research, the experimental devices for the concentration of marine plankton samples mostly use various homemade latex glass straws or siphon devices. Due to the small size and light weight of the plankton itself, coupled with the surface tension of the water body, some of the remaining plankton are often adsorbed on the wall of the glass straw or various siphon devices during the concentration process, which affects the actual effect of concentration. It will reduce the statistical accuracy of the plankton sample number. In addition, traditional enrichment devices require manual long-term operation, which is time-consuming and labor-intensive, and the work efficiency is low.

Contents of the invention

The technical problem to be solved by the utility model is to provide a marine plankton concentration device, which saves time and effort, and ensures the accuracy of concentration of marine plankton samples.

The technical solution adopted by the utility model to solve the technical problem is to provide a marine plankton concentration device, including a sample bottle, a drain pipe and a peristaltic pump, one end of the drain pipe is connected to the sample bottle, the other end is a water outlet, and There is a peristaltic pump, and a detachable screen is set at the end of the drain pipe connected to the sample bottle.

The peristaltic pump is detachably installed in the middle of the drain pipe.

The drainpipe as a whole has a gate-shaped frame structure.

The drain pipe is made of plexiglass.

Beneficial effect

The utility model uses a peristaltic pump to extract the water in the sample bottle, so that the marine plankton in the sample bottle can be concentrated, saving time and effort; at the same time, a screen is set at the water inlet of the drain pipe to prevent the plankton from being drawn out of the sample bottle, ensuring The accuracy of plankton sample concentration was improved.

detailed description

Below in conjunction with specific embodiment, further set forth the utility model. It should be understood that these embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application.

A marine plankton concentration device as shown in FIG. 1 includes a sample bottle 1 , a drainage pipe 3 and a peristaltic pump 4 . The drain pipe 3 is a hollow cylindrical tubular body made of plexiglass, one end is connected to the sample bottle 1, and the other end is a drain port. The peristaltic pump 4 is detachably installed in the middle of the drain pipe 3 to ensure that the liquid in the plankton sample bottle 1 can It is automatically and continuously pumped at a constant speed to achieve the purpose of concentration. The peristaltic pump 4 can be disassembled freely, which is convenient for cleaning and maintenance, and the drainage pipe 3 has a door-shaped frame structure as a whole. The end of the drain pipe 3 connected to the sample bottle 1 is covered with a detachable screen 2. The mesh size of the screen 2 can be freely replaced according to the size of the actual plankton specimen to prevent the plankton from being sucked out of the sample. bottle 1.
