Abstract

The invention provides a deepwater bed sand sampler. A sampling body (3) of a sampling tube (7) which is provided with a percussion trigger (26) and controlled by the percussion trigger is fixed on a bracket (4) through a fixing ring (5), the bracket is provided with a balancing load (6), a hoisting ring (2) positioned on the bracket is used for connecting and hoisting steel cables of the whole sampler, and one end of a percussion rope (1) is connected with the percussion trigger (26) on the sampling body (3). The water depth is not limited, and the sampling depth is adjustable. The deepwater bed sand sampler can sample sand (or mineral) samples from natural riverbeds (or sea beds).

Description

Technical field: [0001] The invention relates to a bed sand sampling device, in particular to a deep water bed sand sampler, which mainly solves the problem of sampling sediment (or minerals) in river beds (or sea beds) of deep water river sections such as the Three Gorges reservoir area of ​​the Yangtze River. Background technique: [0002] Bed sand is the sediment that stays at a certain depth on and below the river bed surface, and is a river bed material formed under specific flow and sediment conditions. In order to understand the characteristics, sources, quantity and temporal and spatial changes of riverbed sediment, it is necessary to carry out sediment testing and collect sediment data systematically to provide a reliable basis for the development of the river basin and the construction of the national economy. [0003] Sediment silts up the river course, which raises the river bed year by year, which is easy to cause the river to flood; the silt of the reservoir re...
