Collecting device for tiny insects in water body

Abstract

The invention relates to the technical field of insect collecting equipment, and discloses a collecting device for tiny insects in a water body. The device is characterized in that a filter screen replacing component is arranged on the left side of a transition block; a fine-hole filter screen is arranged below the filter screen replacing component; a movable telescopic device is arranged on the right side of the transition block; anti-skid lines are sleeved outside the handle; and the telescopic support rod, the telescopic fixing rod and the fixing clamping pin in the movable telescopic device can adjust the adaptive length, aiming at the fact that it is particularly convenient to collect tiny insect samples in field river water to avoid collectors from going deep into water or river grass, on the basis of convenience, the life and property safety of the collectors during the collection of tiny insect samples is ensured, the filter screen replacement component can replace or clean andmaintain the fine-hole filter screen, so that the loss of the fine-hole filter screen during the collection of tiny insect samples is reduced; and reuse of the fine-hole filter screen can reduce thecost, and conform to the theme of today's green recyclable era.

Description

technical field [0001] The invention relates to the technical field of insect collection equipment, in particular to a collection device for tiny insects in water bodies. Background technique [0002] Insects are indispensable species in nature. The density, species and habits of insects in a region have a great impact on the environmental ecology of the region, and the study of the density, species and habits of insects requires careful collection of insects. At present, the methods of collecting insects are mainly divided into four methods: net catching, shaking, searching and trapping, and net catching is the simplest and most direct collection method, and it is also a widely used collection method at present. [0003] However, the existing net catch collection devices on the market are too single in function. If the rod is too long, it will not be easy to collect, and if the rod is too short, it will not be easy to collect, and it cannot be folded. Disassembly, the fin...

Problems solved by technology

[0003] However, the existing net catch collection devices on the market are too single in function. If the rod is too long, it will not be easy to collect, and if the rod is too short, it will not be easy to collect, and it cannot be folded. Disassembly, the fine-pore filter is relatively precise, and it is difficult to clean up impurities such as aquatic plants, which reduces the service life and increases the cost of the experiment
