Abstract

The present invention discloses an acquisition apparatus used for an overlying deposit, and relates to the technical field of environment detection. The present invention comprises a box. A fixing plate is fixedly connected on the box. A feed screw nut is connected on the fixing plate in a sliding manner. A lead screw nut is fixed inside a through hole. A sampling box slot is disposed on a lower side face of the box. A sampling box is connected inside the sampling box slot in a sliding manner. A sliding chute is opened on one pair of opposite inner walls of the box. A pressing plate is connected between the two sliding chutes in a sliding manner. A box cover is connected at an open side of the sampling box in a sliding manner. A top plate is hinged on an outer side face of the other end ofthe sampling box, and the other end of the top plate is hinged with the pressing plate. The pressing plate is rotatablely connected to a lead screw cooperating with the lead screw nut. The box coveris rotatablely connected to a feed screw cooperating with the feed screw nut. According to the acquisition apparatus, the sampling box is connected in the box in a sliding manner, the sampling box protrudes out to sample a deposit, and the box cover is used for protecting the sampled deposit, thereby resolving a problem that detection accuracy is affected because mixing and interference are easilycaused between layers during current deposit sampling.

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 ...
