Title:
PORTABLE WATER BODY MICRO-SURFACE POLLUTANT DETECTION DEVICE AND METHOD FOR USING SAME
Document Type and Number:
WIPO Patent Application WO/2022/134373
Kind Code:
A1
Abstract:
A portable water body micro-surface pollutant detection device, comprising: a float (100), a four-corner bracket (110), a current stabilizer (200), guide rails (300) and a sampling filter screen (400). The float (100) is a hollow cylindrical structure, and the four-corner bracket (110) is separately connected to four corners of the float (100). The current stabilizer (200) is formed by connecting an arc-shaped plate (210) and deflector plates (220) that are symmetrical on two sides, and a telescopic probe (120) is arranged on the inner side of the float (100) away from the current stabilizer (200). Opposite surfaces inside the float (100) are connected to the guide rails (300), and a pair of sliding blocks (310) are arranged on each guide rail (300). A retractor (330) is fixed on the sliding blocks (310), and a clamping device (340) is connected to the top part of the retractor (330). Several detection test papers (410) are adhered to the side of the sampling filter screen (400) away from the water body micro-surface, and the detection test papers (410) are in several rows not arranged in parallel. The detection device is used to detect a large amount of enriched metal ions, microorganisms and other pollutants in the water body micro-surface. A relatively stable sampling water surface is provided inside the float (100) by means of the current stabilizer (200), which eliminates the influence of peaks and troughs caused by the current of the water body, reduces the influence on the sampling surface, and makes sampling and detection more accurate.
