Embodiment Construction

[0037] like figure 1 As shown, the present invention provides a combined adjustable sediment sampler that can obtain multiple mud samples, which includes an upper control part 1 and a lower control part 3 connected by a combined rod part 2, and a sampling device is installed at the lower end of the lower control part 3. Part 4; the upper control part 1 controls the lower control part 3 and the sampling part 4 through the internal control shaft 5, and the top of the internal control shaft 5 is provided with an inner rod handle 6.

[0038] like figure 2 , image 3 The upper control part shown includes a cam 1-1 arranged on the internal control shaft 5, an eccentric brake sleeve 1-2 is arranged on the periphery of the cam 1-1, and a brake shaft 1-3 is arranged outside the eccentric brake sleeve 1-2. The braking shaft 1-3 links to each other with the locking handle 1-4. Since there is a cam on the internal control shaft, no matter the internal control shaft rotates to any angl...

Abstract

The invention relates to a bottom sediment sampler and aims to solve the technical problems that bottom sediment of different depths is difficultly collected by a conventional sampler and the high-precision deep detection and analysis requirements are difficultly met. In order to solve the problems, the invention provides a combined adjustable bottom sediment sampler capable of acquiring multiple sediment samples. The combined adjustable bottom sediment sampler comprises an upper control part and a lower control part which are connected with each other through a combined rod part, wherein a sampling part is arranged at the lower end of the lower control part; the upper control part controls the lower control part and the sampling part through an inner control shaft. The bottom sediment sampler is divided into four mechanisms, and a universal joint is arranged between the adjacent mechanisms, so that the machine is conveniently assembled, and the sampler is convenient to detach and transport.

Description

technical field [0001] The invention relates to a bottom mud sampler, in particular to a combined adjustable bottom mud sampler capable of obtaining various mud samples. Background technique [0002] In order to study the migration, transformation, and accumulation of pollutants between rivers, lakes, reservoirs and sediments and their impact on water bodies, it is necessary to obtain undisturbed sediment samples at different depths in the lower part of the water body for analysis and research, so as to provide decision-making for scientifically formulating governance plans Based on this, it is necessary to provide a certain form of water body sediment sampler. At present, the most widely used water body sediment samplers are: [0003] Grab sampler: This type of sampler has a simple structure and is easy to operate; but it can only obtain shallow sediment samples, and the original sediment layer is too disturbed, so it is difficult to collect in-situ sediment at differe...
