[0002] Phytoplankton is not only the most important primary producer in aquatic ecosystems, but also the main supplier of dissolved oxygen in water. It initiates the food web in aquatic ecosystems and plays a vital role in the energy flow, material circulation and information transfer of aquatic ecosystems. Currently, general environmental monitoring stations monitor phytoplankton by collecting a certain amount of water, then using a special phytoplankton concentration device to allow natural sedimentation for 24 hours, nearly half a meter high, and then taking several dozen milliliters of water samples from the bottom of the concentration device for analysis or identification.

[0003] In the process of realizing the utility model, the inventor found that there are at least the following problems in the prior art that have not been solved: during use, the traditional specialized phytoplankton concentration device is relatively expensive, made of glass, and is also easy to break. If there are a large number of samples to be processed, many monitoring stations consider the cost of the precipitator and first refrigerate the water samples and then precipitate them in batches. The processing time is too long, the work efficiency is low, and the accuracy of the samples is reduced. Therefore, a new technical solution needs to be designed to solve it. Utility Model Content

[0006] Preferably, the bottom end of the closing switch is sealed and connected to the top end of the base, and the bottom end of its internal threaded sleeve is communicated with the top end of the 50 ml sample container.

[0007] Preferably, the rotating ring is rotatably connected to the surface of the mounting ring.

[0008] Preferably, one end of the threaded connector II is integrally formed at the mounting end of the water sample bottle, and the other end of the threaded connector II is sealed and connected to the interior of the threaded sleeve via a thread.

[0009] Preferably, one end of the connector is fixedly connected to one end of the sealing blade, and the other end of the connector is fixedly connected to one end of the arm.

[0010] Preferably, one end of the connecting column is fixedly connected to the other end of the arm rod, and the other end of the connecting column is fixedly connected to the inner wall of the rotating ring.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model combines a base, a threaded connector I, a closing switch and a water sample bottle. When the concentrator is used, the threaded connector I is first closed and the base is installed to the bottom end of the closing switch. Then the threaded connector II on the water sample bottle is installed to the inside of the threaded sleeve, and the rotating ring is rotated clockwise so that the rotating ring drives the arm rod to rotate on the mounting ring through the connecting column. At this time, the other end of the arm rod drives the sealing blade to expand inside the threaded sleeve through the connecting head, so that the sealing blade seals the inside of the threaded sleeve, which greatly reduces the cost of the concentrator from thousands of yuan to tens of yuan, while achieving the same effect. Moreover, the utility model is easy to carry and simple to operate. Plankton sample concentration can be started immediately after the sample is collected. The utility model is suitable for field operations as well as laboratory operations, which saves time in scientific research and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
