The invention discloses a surface water sampling device for environmental monitoring, and relates to the technical field of surface water detection sampling equipment. The surface water sampling device for environmental monitoring comprises a sampler body, the sampler body is composed of a control panel, a sample barrel and a sampling pipe, two peristaltic pumps are arranged on the surface of the control panel, the sample barrel is divided into two spaces which are connected with the output ends of the two peristaltic pumps respectively, a sampling small pipe is arranged in the sampling pipe, and the sampling small pipe is connected with the control panel. The sampling pipe and the small sampling pipe are respectively connected with the input ends of the two peristaltic pumps; a sampling sucker is arranged at one end of the sampling pipe, and a floating surface sampling device is arranged between the sampling sucker and the sampling pipe. By arranging the floating surface sampling device, the sampling suction head and the floating surface sampling device can be used for sampling the water surface of surface water and the position below the water surface, the sampling is effectively carried out on the position where more dust or oil floats on the water surface, the sampling efficiency is improved, and the error of test data is prevented.
Description
technical field [0001] The invention belongs to the technical field of surface water detection and sampling equipment, in particular to a surface water sampling device for environmental monitoring. Background technique [0002] Surface water is water that exists on the surface of the Earth's crust and is exposed to the atmosphere. It is the general term for the four water bodies of rivers, glaciers, lakes and swamps, also known as "land water". It is one of the important sources of water for human life, and a surface water sampler is required when collecting samples of surface water. [0003] At present, when sampling surface water, the sampling tube is put into the water, and the peristaltic pump is started to pump out the water to achieve the effect. It is inevitable to sample the water surface, and then the existing sampler cannot sample the water surface and underwater at the same time when sampling, resulting in inaccurate sampling and affecting the judgment of the te...
