Sampling device for researching attached biocenosis of river ecosystem

Abstract

The present invention discloses a sampling device for researching attached biocenosis of a river ecosystem. The sampling device comprises a main sleeve rod, a first tail end fixing clamping hole and a material taking barrel, a handle rod is fixed to the top end of the main sleeve rod, a first inner ring sleeve is fixedly installed on the inner side wall of the main sleeve rod, a first clamping strip is fixed to the outer side face of an auxiliary sleeve rod, a spring is arranged in the mounting groove, a first tail end fixing clamping hole is formed in the tail end of the main sleeve rod, a second inner ring sleeve is fixed in the auxiliary sleeve rod, a material taking barrel is arranged on the outer side of the top end of the supporting rod, a limiting plate is arranged at the bottom end of the interior of the material taking barrel, and a feeding port is formed in the middle of the sealing cover plate. The sampling device for researching attached biocenosis of the river ecosystem can be operated and used for different river basins, is convenient to adjust and use, can be carried, is convenient for auxiliary operation, is convenient for exhausting air, and can ensure rapid and efficient sampling and use.

Description

technical field [0001] The invention relates to the technical field of river ecosystem research, in particular to a sampling device for studying the attached biological communities of the river ecosystem. Background technique [0002] The river ecosystem is always in the process of dynamic changes, and the river ecology directly affects the development of the surrounding biological environment and the balance of the ecological environment. Therefore, in order to avoid adverse changes in the river ecosystem, regular monitoring of the river ecosystem is required. Sampling and detection of biological communities attached to rivers in order to facilitate timely regulation of river ecosystems; [0003] However, there are still some disadvantages when using the currently commonly used sampling devices for attached biological communities in river ecosystems, such as: [0004] 1. Common sampling devices are mostly used for large-scale river basins. When used, they are not easy to c...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide a sampling device for studying the attached biological communities of river ecosystems, so as to solve the problem that the current river sampling device proposed in the above-mentioned background technology is inconvenient to use for rivers in different regions, and it is inconvenient to adjust operations. It is inconvenient to carry auxiliary equipment, and at the same time it is inconvenient to discharge air, which cannot ensure fast and efficient sampling operations
