Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] 1. Assembly process of the present invention

[0034] according to figure 1 , specifically the sediment sampling device of the present invention is assembled: the sampling head (9) and the support (5), the sampling pipe (6) and the storage pipe (8) are respectively connected by a spiral structure; the piston (7) is put into the connected The sampling tube (6) and the storage tube (8), and then put the assembly from the top of the bracket (5), with the storage tube (8) facing down; screw the top cover (4) through the screw structure; the T-shaped piston The connecting rod (3) enters the sampling tube (6) through the small hole of the top cover (4), and is connected to the piston (7) by a screw. Before sampling, the piston (7) must be pushed to the sampling head through the T-shaped piston connecting rod (3) (9) sampling port; determine the number of s...

Abstract

The invention aims to further guarantee that the collected bottom mud is not disturbed on the premise of guaranteeing that the bottom mud which is subjected to sequence fidelity is collected. A portable fidelity cylindrical bottom mud sampler mainly comprises a bottom mud collection device and a storage device, wherein the collection device comprises a support, a sampling pipe, a piston, a sampling head, and the like; and the storage device comprises a storage pipe, a storage pipe foundation, a top cover and the like. When the bottom mud is collected, the storage pipe is connected to the lower part of the sampling pipe and is extended into the support; and the piston in the collection device can prevent water from being mixed with the bottom mud and can absorb the bottom mud into the storage pipe and the sampling pipe to ensure that the bottom mud is not distorted. After collection is completed, if the bottom mud is needed to be layered, the piston is pushed to push the bottom mud out for layering; and if the collected bottom mud is needed to be subjected to fidelity further, the sampling pipe can be separated from the storage pipe, and the storage pipe can be stored. The high-efficiency portable fidelity cylindrical sampler is particularly suitable for investigation of pollution characteristics and repair research of the bottom mud of shallow water.

Description

technical field [0001] The invention relates to the field of bottom mud collection and analysis, and is particularly suitable for the scientific research of shallow water body bottom mud. technical background [0002] Sediment is a mixture of clay, silt, organic matter and various minerals, which is deposited at the bottom of the water body after long-term physical, chemical and biological actions and water transport. The pollution sources of water body generally include two types: internal source and external source. The internal source pollution is caused by the release of various pollutants from the sediment to the water body, and the external source pollution is mainly caused by the discharge of pollutants into the water body by human beings in production and life. Caused. In recent years, although researchers have effectively alleviated foreign aid pollution through various methods and technologies, the pollution of water bodies has not yet declined. Therefore, the st...
