Shallow superficial layer sludge sampler

Abstract

The invention discloses a shallow superficial layer sludge sampler. The shallow superficial layer sludge sampler comprises a handle, a sampling cylinder, a handle, a connection rod, a triangular bracket, a spring, a linkage shaft, a rotation shaft and a base plate, wherein the handle is arranged on the outer side of the sampling cylinder; two ends of the handle are fixed on the outer side wall of the sampling cylinder; the handle is fixed on a grip; the triangular bracket is fixed at the top of the sampling cylinder; the connection rod passes through a middle hole of the triangular bracket; the top of the connection rod is fixed on the handle; the upper end of the spring is fixed on the triangular bracket; the lower end of the spring is fixed on the connection rod; the lower end of the connection rod is connected with the linkage shaft; the bottom of the sampler is sealed by the base plate; the cross section of the base plate is connected with the rotation shaft; the rotation shaft is fixed on the inner side wall of the bottom of the sampling cylinder; the top of the base plate is fixedly connected with two end points of the linkage shaft. The shallow superficial layer sludge sampler is reasonable in design, simple and convenient to use and convenient to carry and maintain; and is convenient for on-site inspection workers to sample sludge.

Description

technical field [0001] The invention relates to a sampler for collecting bilge mud samples. Background technique [0002] With the global economic integration and the vigorous development of the shipping industry, on the one hand, it has greatly promoted the rapid growth of international trade. Exchange also provides faster and more convenient conditions for the invasion of alien species and the spread of infectious diseases, posing a potential threat to human health. [0003] During the voyage of international ships, the ballast water is constantly exchanged with the outside world, and some silt and various aquatic organisms and microorganisms are gradually deposited and lodged at the bottom of the ballast tank. Silt has various conditions required for the life of many aquatic organisms and microorganisms, and is a good base for the growth, habitat and reproduction of aquatic organisms and microorganisms. Compared with ballast water, the living environment of various orga...

Problems solved by technology

[0004] The health and quarantine department at the border port is responsible for the biohazard monitoring of the ballast water and bottom silt discharged from the ballast tank of international ships. For the collection of ballast tank bottom silt samples, tools such as negative pressure tube mud extractors are often used. It has the characteristics of different viscosities and thin mud layers. It is inconvenient to maintain after the tool is used more times. It is necessary to develop tools that are easy to use and easy to maintain.
