3results about How to "Implement automatic sampling" patented technology

The utility model discloses a device for realizing automatic sampling and monitoring of a sludge settling ratio by using laser ranging, which comprises a monitoring box body, a transparent measuring cylinder is arranged in the monitoring box body through a stabilizing mechanism, and an extraction assembly communicated with a liquid inlet at the top end of the transparent measuring cylinder is arranged in the monitoring box body. The input end of the extraction assembly extends into an external sludge tank, a laser distance measuring sensor is further arranged on the inner top wall of the monitoring box body through an adjusting mechanism, and the laser distance measuring sensor is matched with the transparent measuring cylinder. According to the invention, periodic automatic sampling can be realized and the sludge sedimentation ratio of each round can be recorded; meanwhile, the automatic sampling and monitoring device is simple and rapid in process, and can replace manual sludge mixed liquid sampling and sludge sedimentation ratio detection, so that automatic sampling and automatic alarm for sludge sedimentation ratio abnormity are realized, the whole process is automatically recorded without human intervention, and the accuracy of a final monitoring result can be improved.

The utility model relates to the technical field of water quality monitoring devices, in particular to an on-line automatic water quality monitoring device. Comprising a positioning part and a connecting hose, the connecting hose is provided with a plurality of sampling parts, each sampling part is provided with a snorkeling part, and the snorkeling parts are used for driving the heights of the sampling parts; the positioning part is provided with a suction pump, the connecting hose is connected with the suction pump, the snorkeling part comprises a positioning rod and an adjusting air bag, the adjusting air bag is connected with the connecting hose, the adjusting air bag is provided with an air pump, and when the air pump operates, the buoyancy of the adjusting air bag is changed, so that the adjusting air bag moves along the positioning rod. Through the design of the snorkeling part, the height of the sampling part can be flexibly adjusted, and automatic sampling of water bodies with different depths is realized, so that the water quality condition is reflected more comprehensively.
