Problems solved by technology

[0003] In the process of biological inspection, a group of sampling often has a great chance, so when collecting plankton, it is often carried out multiple times, and multiple collection groups are inspected, and the accuracy is higher. The existing collection device, usually It is collected by the collection tube at the riverside. It is cumbersome to repeat it many times, and all of them are at the riverside. Collection cannot be carried out in the middle of the river, so it still has a large chance

Abstract

The invention relates to the technical field of biological inspection, and in particular, relates to a plankton collecting device suitable for mountain rivers and streams, wherein the plankton collecting device comprises two fixing frames and a fixing rod, hoops are arranged on the upper surfaces of the fixing frames, and a balancing weight is arranged at one end of the fixing rod. A plurality offirst fixing blocks and a plurality of second fixing blocks are fixedly connected to the outer surface of the other end of the fixing rod, a rotating shaft is rotatably connected between one first fixing block and one second fixing block, a limiting assembly is arranged at the end of the rotating shaft, and a connecting rope is fixedly connected to the outer surface of the rotating shaft; the bottom end of the connecting rope penetrates through a through groove and is fixedly connected with a plurality of collecting cylinders, so that multiple sets of collecting cylinders can be used for collecting at the same time, meanwhile, the fixing rod is transversely placed above a river, then different positions in the river can be collected, and the inspection accuracy is improved more scientifically and effectively.

Description

technical field [0001] The invention relates to the technical field of biological inspection, in particular to a plankton collecting device suitable for rivers and streams in mountainous areas. Background technique [0002] Plankton is small in size, mostly invisible to the naked eye, suspended in the water layer with poor swimming ability, and mainly moved by water flow, called plankton, plankton is a class of organisms classified according to their lifestyle Groups, not species. [0003] In the process of biological inspection, a group of sampling often has a great chance, so when collecting plankton, it is often carried out multiple times, and the inspection of multiple collection groups has higher accuracy. The existing collection device, usually It is collected by the collection tube at the riverside. It is cumbersome to repeat it many times, and all of them are at the riverside. Collection cannot be carried out in the middle of the river, so it still has a large chanc...
