Description
技术领域technical field

It can exchange materials with the overlying water body through various channels. The migration and transformation of heavy metals, organic chlorine and other pollutants in sediments have great impact on aquatic organisms and The living environment of benthic animals plays an important role. The "health" of sediments is undoubtedly related to the health of aquatic ecosystems, and then affects humans through the food chain. Therefore, it is of great significance to collect and monitor sediment samples .
目前国内外研制开发的沉积物采集装置种类繁多，主要包括重力采样器、活塞式采样器、连杆式采样器、冷冻式采样器以及钻进式采样器等，其中便携式重力采样器在水体沉积物研究中应用普遍，具有便于携带、操作简单的特点。重力采样器分为抓斗式和柱状式两类，抓斗式采样器结构简单、操作方便，但仅适合采集表层20cm左右的样品，而且采样厚度不可控，对沉积物样品扰动大、密封性差，易造成样品流失和采集效率低等问题，通常只用于表层混合态沉积物样品的采集。At present, there are many types of sediment collection devices developed at home and abroad, mainly including gravity samplers, piston samplers, connecting rod samplers, freezing samplers, and drilling samplers. It is widely used in biological research, and has the characteristics of portability and simple operation. Gravity samplers are divided into two types: grab type and columnar type. The grab type sampler has a simple structure and is easy to operate, but it is only suitable for collecting samples of about 20 cm from the surface, and the sampling thickness is uncontrollable, causing large disturbance to sediment samples and poor sealing. , It is easy to cause problems such as sample loss and low collection efficiency, and is usually only used for the collection of surface mixed sediment samples.
柱状式采样器是通过垂直插入沉积物中获取未受扰动的柱状沉积物样品，所取得的样品具有很好的代表性，目前使用的柱状式采样器多结构复杂，体积较大且笨重，需要专门的起吊设备，价格昂贵，操作不方便，而且很多检测地区地形崎岖,不便于携带重型设备。The columnar sampler is inserted vertically into the sediment to obtain undisturbed columnar sediment samples. The samples obtained are very representative. The columnar samplers currently used are mostly complex in structure, large in size and heavy, requiring Specialized lifting equipment is expensive and inconvenient to operate, and the terrain in many testing areas is rugged, making it difficult to carry heavy equipment.
目前沉积物取样装置结构复杂、成本高，采样厚度不可控的技术问题是本领域技术人员亟待解决的技术问题。Currently, the sediment sampling device has complicated structure, high cost, and uncontrollable sampling thickness technical problems are technical problems to be solved urgently by those skilled in the art.
