Embodiment Construction

[0015] As shown in the drawings, the fresh sediment sampler of the present invention includes a lifting rod 2 , a cup holder 3 and a base 8 . The lifting rod 2 is formed by connecting stainless steel pipes with threads at both ends through the pipe joint 7, and the length of the lifting rod 2 can be adjusted according to the depth of the water body to ensure that the cup holder 3 enters a suitable sampling depth. The upper end of the lifting rod 2 is provided with a handle 1, which is convenient for placing and taking out the whole sampler, and the bottom end of the lifting rod 2 is connected with the base 8 by threads. Three groups of cup brackets 3 are installed on the lifting rod 2, and the quantity of the cup brackets can be arbitrarily increased or decreased according to actual conditions, and the cup brackets 3 are fixed on the lifting rod 2 by fixing bolts 6 thereon. Every group of cup holders 3 is provided with three cup holders 5, and the quantity of the cup holders 5...

Abstract

The invention provides a regenerate sediment sampler which comprises a lifting rod, cup brackets and a base, wherein, the bottom end of the lifting rod is connected on the base, the lifting rod is at least provided with one group of cup brackets, each group of the cup brackets is at least provided with one cup stand, and a mud-containing cup is placed on the cup stand. The lifting rod is formed by connecting subsection rods, two ends of which are provided with screw thread, through pipe joints, and the length can be adjusted and changed. The cup stands of each group of the cup brackets on thelifting rod are distributed in different vertical directions so as to avoid the interference of the cup stand on the upper layer to that of the lower layer in the collection process of the regeneratesediment as far as possible. In the sampling process, collecting personnel stand on the shore or the ship to operate, put the sampler into a sampling point vertically, and collect the new settled sediment in the mud-containing cup within the set sampling period. The sampler has simple structure and convenient use, and can realize scientific and reasonable regenerate sediment sampling, thus solving the problem that regenerate sediment sample collection can not be carried out ever since a long time ago.

Description

technical field [0001] The invention relates to a sampler used for collecting fresh sediment in rivers, lakes or reservoirs, and belongs to the technical field of environmental detection. Background technique [0002] Nutrients are constantly being exchanged between the overlying water bodies of rivers, lakes, and reservoirs and sediments. On the one hand, new sediments will carry nutrients and deposit them in the bottom sediments. On the other hand, the nutrients in the bottom sediments Salt is released into the overlying water body. Therefore, in the process of pollution control of eutrophic rivers, lakes, and reservoirs, it is necessary to analyze and understand the formation rate and physical and chemical properties of new sediment. In the collection process of new sediment, it must be collected before the new sediment is deposited on the bottom sediment, otherwise, once the new sediment contacts the original sediment, there will be a process of nutrient exchange, and i...
