Bottom mud collecting device

Abstract

The invention discloses a bottom mud collecting device. The bottom mud collecting device comprises a mud storage box which is formed by combining two hollow quarter cylinders together, wherein the middle upper parts of the two hollow quarter cylinders are connected through a bearing; a semi-automatic switch is arranged at the upper part of the mud storage box; the semi-automatic switch comprises aplug and a bolt groove; clamping grooves are arranged in the upper positions of the left side and the right side of the mud storage box respectively; a water permeation hole is arranged in the upperpart of the mud storage box; the upper part of the mud storage box is connected to a connecting rod; and the end part of the connecting rod is connected to a drawing wire. The device is easy to operate, the primitiveness of the collected bottom mud can be ensured, the collected bottom mud has hierarchy and representativeness, samples can be disturbed and mixed in a hierarchical manner, when the bottom mud is cut in the water bottom, the bottom mud samples can be prevented from being stirred as much as possible, and the accuracy of later test analysis is improved in order to have an important significance for later hierarchical analysis and assay of the bottom mud. The device has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of environmental detection, in particular to a bottom mud collection device. Background technique [0002] When conducting scientific research on aquatic ecology, it is often necessary to analyze the physical, chemical and biological indicators of the bottom material of the water area, such as the pigment in the sedimentary phase, the endowment form of nutrients, and the law of adsorption and release of nutrients in the water body. What is studied is the boundary part between the sedimentary facies and the water body, and the surface layer of the bottom mud. [0003] At present, the research on sediment collection methods in water bodies is not very deep in our country. Most of them rely on experimenters to operate on the water surface and rely on gravity to make the equipment sink. However, the gravity of the equipment is fixed, and the collected sediment is not layered. , which has brought great troubles ...
