Portable undisturbed sludge sampler

Abstract

The invention relates to the technical field of river and lake underwater sludge sampling, in particular to a portable undisturbed sludge sampler. A drainage control system, a chain type cabin door and a cabin door chamber are effectively combined, and the original state of a sample can be well guaranteed. Meanwhile, an elastic cushion rail, a pulley and the like are combined, operation is convenient and labor-saving, manufacturing, using and later maintenance are easy, the manufacturing cost is low, and power equipment can be manually operated or connected with motor equipment. By adopting the sampler disclosed by the invention, the problems of other common samplers can be well solved. In a complex underwater environment, the drainage control system, an extension auxiliary accessory, a switch rotating groove, a side wall switch system, an elastic track of the sampler and a rotating support rod of the sampler are matched with one another to ensure that a taken sample is kept in an original shape, a series of matched cutting ring samplers can be combined to carry out subsequent related experiment operations, so that unnecessary procedures are reduced, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of underwater sludge sampling in rivers and lakes, in particular to a portable undisturbed sludge sampler. Background technique [0002] Since the introduction of the lake chief system, the healthy development of river and lake ecology has attracted the attention of Chinese people. The accumulation of rivers and lakes has seriously affected the changes in the elevation of the bottom of the riverbed, affecting the safe operation of waterways and other water conservancy projects, and at the same time affecting the quality of water bodies and the survival of aquatic organisms. [0003] The river and lake dredging project has become an indispensable and important part of river and lake governance. With the advancement of the project, a large amount of silt in the river and lake will be cleared out, and where the silt will go has become an urgent problem to be solved. In order to rationalize the treatment of silt...
