Description

Technical Field

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

[0002] During the use of electrical equipment, dirty conductive substances such as solids, liquids or gases adhere to the insulation surface of the electrical equipment. When encountering meteorological conditions such as fog, dew, rain or melting ice (snow), the dirt layer on the insulation surface becomes damp, which will lead to increased conductivity and leakage current. Under the operating voltage, local arcs may be generated and develop into surface flashovers, which poses a great hidden danger to the healthy operation of electrical equipment. Therefore, preventing and reducing the occurrence of flashover accidents is of great significance to the safe and reliable operation of the power grid.

[0003] By measuring the degree of pollution on site, it is possible to provide reference suggestions for the configuration of insulators, insulation cleaning, etc., and it is an effective measure to prevent pollution flashover accidents. That is, by measuring the equivalent salt density and ash density of the reference insulator surface at the site or experimental station, the chemical composition of the pollutants is analyzed. However, pollution sampling is mostly done through sampling cloth or sponge. However, a single sampling cloth or sponge wiping not only cannot attach pollutants of all particle diameters to the surface of the sampling cloth, but also the pollutants adsorbed on the sampling cloth or sponge cannot be completely washed into deionized water, resulting in a large deviation in the mixed liquid of pollutants on the surface of the insulator, resulting in inaccurate measurement of the equivalent salt ash density. In summary, the existing pollution sampling devices still have the following problems:

[0004] A single sampling cloth or sponge cannot attach all particle diameters of dirt to the surface of the sampling cloth, and the dirt adsorbed on the sampling cloth or sponge cannot be completely washed into deionized water, which affects the detection effect. Utility Model Content

The upper insulator contamination sampling cloth and the lower insulator contamination sampling cloth are connected to form a pocket-type design. When in use, the sampling device is turned over and opened, and the device is put on the hand of the sampling personnel from the opening. First, one side is used to wipe the surface of the insulator to be sampled, and then the other side is used to continue wiping. If there is stubborn dirt, it can be wiped repeatedly until it is clean, which not only improves the sampling effect of the device, but also after the sampling work is completed, the device can be cleaned to facilitate repeated use of the device.

The first magnet and the second magnet are adsorbed, so that the card plate can be quickly clamped in the installation box, and it can be taken out by just pulling the pull plate.

[0011] Preferably, the pull plate is T-shaped.
