Description

Technical Field

[0001] The utility model relates to the technical field of plankton collection, in particular to a plankton collection net. Background Art

[0002] Plankton is an aquatic organism that lives suspended in water, including two major categories: phytoplankton and zooplankton. Usually, plankton individuals are very small, but there are many of them and they are widely distributed. They occupy an important position in the aquatic biological world. They are not only an important bait basis for fish, but their number to a certain extent indicates the level of water productivity. Moreover, their community structure and species composition are often used to evaluate the current status of the water ecological environment. Therefore, plankton surveys are usually one of the most important projects in water ecological surveys. Traditional plankton collection nets are mostly of a relatively simple structure, generally only a single net, which needs to be connected to the collection net by a long pole. However, due to the long length of the long pole, it is not easy to carry when collecting in the wild, and it occupies a large volume, which often causes inconvenience to the sampler when collecting.

[0003] According to the search report of the novelty search agency, announcement number CN218736721U discloses a plankton collection net, including an adjusting rod, on which an adjusting mechanism, a disassembly mechanism and a collection mechanism are arranged; the adjusting mechanism includes a fixing rod, which is inserted into the left side of the adjusting rod, a fixing sleeve is sleeved on the left outer side of the fixing rod, and the lower end of the fixing sleeve is fixedly connected to a connecting rod, and a moving rod is sleeved on the outer side of the lower end of the connecting rod, and the lower end of the moving rod is fixedly connected to a lifting ring, and the lifting ring is fixedly connected to a fixing plate through a first lifting rope; by setting the adjusting mechanism, the adjusting rod is rotated to a suitable position by rotating the adjusting rod, and by providing an anti-slip sleeve on the adjusting rod, the adjusting rod can be prevented from slipping when used by the staff, and then the moving rod is adjusted to a suitable position by unlocking the locking bolt on the moving rod, and then locked by the locking bolt, so as to facilitate the adjustment of the use range of the collection net according to needs.

[0004] The above technology discloses a plankton collection net, which can adjust the vertical length by telescopically adjusting the connecting rod and the moving rod through the sleeve arrangement, so as to adjust the lowering length. However, it still has the following shortcomings: 1. When the river surface is at a low position, a relatively long rod is still required to adjust the vertical lowering length by telescopically adjusting the vertical lowering length by using a simple moving rod and a connecting rod, which is subject to great limitations and is difficult to be used for collecting plankton in water of various depths, and the applicability is not ideal; 2. After collection, the plankton contains a large amount of water, and it takes a long time to wait for the water to flow out, and the dehydration efficiency is not ideal, which reduces the work efficiency of plankton collection. In view of this, the present application proposes a plankton collection net. Utility Model Content
