Abstract

The invention discloses a vertical overlying deposit layered collection device and method. The device comprises a collector, a fixing rack (2), an insertion rod (3) and a switching device (4), wherein the collector comprises a top plate (11), a back plate (12), a left side plate (13), a right side plate (14) and at least one positioning plate (15); one side of each positioning plate (15) is fixed in a fixing groove of the left side plate (13), and the other side of each positioning plate (15) is fixed in a fixing groove of the right side plate (14); through holes are formed at a part, which is positioned on the outer side of the left side plate (13), of the left end of the top plate (11) and in a part, which is positioned on the right side plate (14), of the right end of the top plate (11); and the switching device (4) comprises a left retaining door (41), a right retaining door (42) and a fixing plate (43). The collection device is adjustable in sampling thickness, accurate in sampling, convenient to operate, light in weight, detachable and convenient to carry.

Description

technical field [0001] The invention relates to a sample collection device, in particular to a vertical surface sediment layered collection device and a collection method. Background technique [0002] Sediment is an important part of waters such as rivers, lakes, reservoirs, and oceans. 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 . [0003] At present, there are various kinds of sediment collection devices researched and developed at home and abroad, mainly including gravity sampler, piston sampler, connecting rod sampl...
