Description

Technical Field

[0001] The utility model relates to the technical field of wastewater sampling, in particular to a portable wastewater sampling device. Background Art

[0002] Wastewater, waste gas and noise are recognized as the three major natural hazards. Wastewater refers to domestic sewage, industrial wastewater, and other useless water such as initial rain runoff into sewer pipes. If wastewater is discharged directly, the toxic and harmful substances in it will seriously pollute the soil and will also be enriched in the human body through the food chain, causing harm to the human body.

[0003] At present, a Chinese utility model with announcement number CN212458994U discloses a portable sampling device for wastewater detection, including a telescopic rod, the telescopic rod includes a plurality of sleeves which are arranged in sequence, a mandrel is provided at the front end of the sleeve, a fixing ring is tightly welded to the outer surface of the sleeve and the mandrel, a sleeve is provided on the outer wall of the mandrel, a winding mechanism is provided at the rear of the telescopic rod, the winding mechanism includes a mounting tube, a winding reel is provided on one side of the mounting tube, a connecting rope is wound in the winding reel, one end of the connecting rope passes through the fixing ring and the sleeve in sequence and is tied with a sampling bottle. This utility model sinks the sampling bottle into the water by adjusting the length of the connecting rope in the winding mechanism, which is convenient for collecting wastewater at different depths in the river and improving the detection effect. The retractable rod is easy to carry, which solves the problem that the existing sampling device for wastewater sampling is large in size, troublesome to carry, can only detect wastewater above the wastewater river, and has poor detection effect.

[0004] Before the wastewater is discharged, a wastewater sampling device is needed to sample and test the wastewater to ensure that the wastewater meets the discharge standards before it can be discharged. Existing wastewater sampling devices, in order to facilitate carrying, mostly use test tubes to extract and sample the wastewater, but most test tubes have simple structures. After the sampling is completed, it is easy to cause pressure on the pull rod, thereby causing the wastewater to leak out from the test tube. In the process of sampling the wastewater, the test tube needs to be immersed in the wastewater for sampling. This process may cause direct contact between the staff and the wastewater, which may cause harm to the staff. Utility Model Content
