Description

Technical Field

[0001] The utility model relates to the technical field of sampling equipment, in particular to a river channel regulation sampling device. Background Art

[0002] Rivers are carriers of water resources and are one of the most basic natural resources related to human survival and life. The development, utilization, management and protection of water resources are inseparable from rivers, an important carrier. Wetlands in river regulation projects are called "kidneys of the earth". They have a powerful ability to purify sewage. Wetlands are one of the most self-purification ecosystems in the natural environment.

[0003] The water flow in wetlands is slow, which is conducive to sedimentation. A variety of plants and microorganisms grow and live in wetlands, and the purification capacity of the same area is 1.5 times that of forests. Therefore, river regulation projects can effectively reduce pollutants in water and reduce pollution to surrounding farmland irrigation and drinking water. In the process of river regulation, the water quality of the river must first be understood through sampling. Traditional sampling equipment is generally implemented manually, and it is not easy to collect water quality samples at different depths. Utility Model Content
