Abstract

The invention discloses a collection device for surface sediments and relates to the technical field of environmental detection. The invention comprises a box body; a fixing plate is fixedly connected to the box body, a screw nut is slidably connected to the fixing plate, and a screw nut is fixed in the through hole; A sampling box is connected; a chute is provided on the opposite inner wall of the box body; a pressure plate is slidably connected between the two chutes, and a cover is slidably connected to the opening side of the sampling box; a top plate is hinged on the outer side of the other end of the sampling box, and the other end of the top plate is connected The pressing plate is hinged; the pressing plate is rotatably connected with a lead screw matched with the lead screw nut; the box cover is rotatably connected with a lead screw matched with the lead screw nut. The present invention slides and connects the sampling box in the box, uses the sampling box to protrude to sample the sediment, and protects the sampled sediment through the box cover, which solves the problem of easy mixing and interference between layers when sampling the existing sediment. Issues affecting detection accuracy.

Description

technical field [0001] The invention belongs to the technical field of environmental detection, in particular to a collection device for surface sediment. Background technique [0002] In order to detect the distribution of pollutants in shallow water sediments, it is necessary to collect sediments or water samples at the bottom of the water body, and conduct layered research on the sediments, and maintain the layered state of the sediments during sampling, and avoid sediments at different depths mutual contamination between them. [0003] At present, the methods of collecting sediment at the bottom of the water body are mainly borehole sampling and grab sampler sampling, but these two sampling methods are easy to cause mutual mixing between sediment layers when collecting sediment, resulting in different pollutants. The pollution status between layers cannot be accurately detected. [0004] Therefore, it is urgent to design a sampling device that is convenient to use and ...
