Description

Technical Field

[0001] The utility model relates to the technical field of water quality inspection, in particular to a sampler. Background Art

[0002] Water quality testing is the detection and analysis of the chemical, physical and biological properties of water to determine its quality, purity and suitability. This test usually includes the detection of multiple parameters such as pollutants, nutrients, suspended matter, microorganisms, dissolved oxygen, pH value, etc. in the water to assess whether the water is suitable for drinking, agricultural irrigation, industrial use or other specific purposes. Before testing the water quality, it is usually necessary to sample the water source, which requires the use of a sampler. A sampler is a device or tool for collecting samples. It is used to obtain samples of water or other liquids. The structure and form of the sampler can be of many kinds, including water sample bottles, measuring instruments, automatic samplers, etc. Through the use of samplers, samples can be collected from the water body within a certain period of time and at a specific location to ensure that the sample represents the situation of the entire water body, facilitating comprehensive analysis and evaluation.

[0003] When sampling water through a sampler, since the water contains certain impurities, these impurities cannot be well intercepted or removed during the water extraction process, so the impurities will enter the collection bucket along with the water. In subsequent inspections, the presence of impurities will easily affect the accuracy of the inspection, thereby reducing the inspection effect and quality. Therefore, in order to solve the above problems, a sampler is proposed. Utility Model Content

[0025] Furthermore, the fixing rods 26 are in two groups and fixedly connected to the collecting barrel 12, and the pull rods 27 and the insertion rods 24 are fixedly connected. By the movement of the pull rods 27 on the surface of the fixing rods 26, the insertion and separation of the insertion rods 24 and the first slots 25 can be realized, and then the connection block 22 can be limited and released, thereby facilitating the fixing and disassembly of the filter plate 2 and the collecting barrel 12, and facilitating the cleaning of impurities filtered out of the filter plate 2.

[0030] By wrapping the water inlet pipe 14 around the surface of the fixing column 36, the disc 37 can block the water inlet pipe 14 to prevent the water inlet pipe 14 from slipping, and then pull the second connecting rod 33 to separate the clamping rod 34 from the second slot 35 under the action of the second connecting rod 33. At this time, the movable rod 32 will move on the inner side of the first connecting rod 3 and make the second spring 31 in a stretched state.
