Problems solved by technology

At present, the general sediment sampling equipment needs to use boats or other auxiliary conditions to reach the sampling point. For some small lakes and rivers, without auxiliary conditions such as boats and bridges, it is impossible to collect sediment samples far from the shore. lead to unrepresentative samples

Abstract

The invention relates to a support type bottom mud collecting device which comprises a grab bucket, telescopic rods, a rotating connector, a rotating wheel and a tripod. The grab bucket is connected with the first telescopic rod through a rotating wheel and a first rope, and the depth of the grab bucket in water is controlled by adjusting the length of the first rope through a handle; the first telescopic rod and the second telescopic rod stretch out and draw back to the needed length through buckles; the tripod and the first telescopic rod are fixed through the rotating interface and the second telescopic rod, and sampling personnel can rotate the first telescopic rod to control the direction; a second rope provides supporting force for the first telescopic rod to reinforce the device. The bottom mud collecting device is suitable for collecting bottom mud of small lakes, rivers and the like with the width within 10 meters without assistance of ships, bridges and the like. The bottom mud collecting device is convenient to disassemble, assemble and carry, simple and easy to operate, and a sampler can conveniently collect a bottom mud sample on the shore.

Description

technical field [0001] The invention relates to the technical field of environmental sampling, in particular to a bracket type sediment collection device. Background technique [0002] Water pollution is a common problem in my country. Once the sediment of lakes and rivers is polluted, it will become the internal pollution source of the water body and affect the water body environment for a long time. In order to study the migration, transformation and accumulation process of pollutants between the water body and the sediment, and its impact on the water environment, it is necessary to take sediment samples from the water and detect and analyze the pollutants in them. At present, the general sediment sampling equipment needs to use boats or other auxiliary conditions to reach the sampling point. For some small lakes and rivers, without auxiliary conditions such as boats and bridges, it is impossible to collect sediment samples far from the shore. resulting in unrepresentati...
