Handheld portable underwater depth-fixed sludge undisturbed sampler

Abstract

The invention relates to the technical field of underwater depth-fixed sludge undisturbed sampling, and particularly relates to a handheld portable underwater depth-fixed sludge undisturbed sampler. The handheld portable underwater depth-fixed sludge undisturbed sampler adopts organic combination of a drainage control device, a chain type cabin door and a cabin door chamber, can greatly ensure theundisturbed property of a sample, can ensure that the sampled sample keeps the undisturbed property through related cooperation of the drainage control device, an extension auxiliary accessory, a side wall switch system, an elastic track of the sampler and the like in a complex underwater environment, and can be combined with a matched series of cutting ring barrels to perform subsequent relatedexperiment operation, so that unnecessary procedures are reduced, and the cost is reduced. The handheld portable underwater depth-fixed sludge undisturbed sampler has the characteristics of simplicityand convenience in sampling, capability of opening and closing the cabin door chamber of a sampling cabin underwater, small interference to the undisturbed property, easiness in maintenance, low construction cost and the like; meanwhile, the series of cutting rings are arranged in the handheld portable underwater depth-fixed sludge undisturbed sampler, so that cutting ring sampling in a laboratory is also completed after sampling is finished; the handheld portable underwater depth-fixed sludge undisturbed sampler is more suitable for small-amount collection during academic research.

Description

technical field [0001] The invention belongs to the technical field of undisturbed sampling of underwater depth-determining mud, in particular to a hand-held convenient underwater depth-determining mud undisturbed sampler. Background technique [0002] In recent years, with the development of the national economy and the improvement of people's living standards, the discharge of three wastes has brought many adverse effects on people's living environment, and has seriously affected the surrounding living environment. Especially the pollution of rivers and lakes has brought a lot of inconvenience to the development and construction of cities. Since the introduction of the lake chief system, the healthy development of river and lake ecology has attracted the attention of Chinese people. The dredging treatment of rivers and lakes has become an important part of the healthy development of rivers and lakes, and how to collect the undisturbed underwater silt is particularly impor...
