Portable sediment sampler and sampling method

Abstract

The invention discloses a portable sediment sampler and a sampling method. The sampler comprises a fixed support, a sampling rod and a sampler, wherein the fixed support is connected with a fixing device, the sampling rod is connected with a sleeve, the sleeve is ball-jointed on the fixed support, a detachable cylinder is also mounted below the sleeve, one end of the cylinder is located on the fixed support, the sampling rod comprises a fixed rod and a telescopic rod, the sampler is mounted at one end of the telescopic rod, a sampling shovel is mounted at one end of the sampler and connected with the fixed rod through a string, the sampling shovel comprises an upper clamping piece and a lower clamping piece which are mounted on the sampler through hinged shafts, and tail ends of the upperclamping piece and the lower clamping piece are connected through a spring. The string is tensioned, the sampling shovel is opened, the sampler works, after the sampler finishes the work, the string is loosened, and the sampling shovel is closed. The portable sediment sampler can sample riverbed sediment at different depths, ensure that the sampling rod rotates freely and keep stable.

Description

technical field [0001] The invention relates to a portable sediment sampler and a sampling method, belonging to the field of sediment sampling. Background technique [0002] Due to the discharge of production and domestic sewage, the ecological problems of rivers have been difficult to be effectively treated. In recent years, with the reduction of sewage discharge, the quality of water in rivers has been improved to a certain extent, but the sediment pollution of riverbeds in rivers is still serious, and the polluted sediment will cause long-term pollution to rivers, so it is urgent to The bed sediment in the river is sampled and monitored. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a portable sediment sampler and a sampling method, which can sample riverbed sediment at different depths, ensure the free rotation of the sampling rod, and maintain stability . [0004] ...
