Sewage sampling device

Abstract

The invention discloses a sewage sampling device which comprises a sampling barrel provided with a material taking opening and a material discharging opening, a first sealing plug used for closing thematerial taking opening, a second sealing plug used for closing the material discharging opening, a first linkage device and a second linkage device, and the first linkage device and the second linkage device are mounted on the sampling barrel; the sampling barrel is connected with the first sealing plug through the first linkage device; the first sealing plug is connected with the second sealingplug through the second linkage device. The device has three working states, wherein the first working state is that the first sealing plug is in sealed connection with the material taking opening and the second sealing plug is in sealed connection with the material discharging opening; the second working state is that the first sealing plug leaves the material taking opening, and the second sealing plug is in sealed connection with the material discharging opening; the third working state is that the first sealing plug leaves the material taking opening, and the second sealing plug leaves the material discharging opening. The sewage sampling device is simple in structure and convenient to operate, rapid sampling and rapid discharging can be achieved, meanwhile, sludge can be fully pouredout, dredging work of the dredging device is more convenient and efficient, and then the sampling efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of sampling devices, in particular to a sewage sampling device. Background technique [0002] As one of the most important components in nature, water bodies are not only inseparable from water bodies in people's daily life, but also play an important role in industrial and agricultural production, but now with the development of agriculture, water bodies in rivers have been affected For more serious pollution, in order to restore the healthy state of the water body, it is usually necessary to collect and test the sewage in the river. [0003] At present, when sampling river sewage, sampling cylinders are usually used to sample the sewage in the river, and because the river contains a lot of silt, when performing layered sampling, the silt easily enters the sampling cylinder, and the existing sampling cylinder The cover is located inside the sampling cylinder. After sampling, it is difficult to pour out the...

Problems solved by technology

[0003] At present, when sampling river sewage, sampling cylinders are usually used to sample the sewage in the river, and because the river contains a lot of silt, when performing layered sampling, the silt easily enters the sampling cylinder, and the existing sampling cylinder The cover is located inside the sampling cylinder. After sampling, it is difficult to pour out the sludge, which affects the reuse of the sampling cylinder. Therefore, we propose a sewage sampling device with a different structure from the existing sampling cylinder.
