Title:
DEVICE FOR DETECTING CONCENTRATION OF CONCENTRATED POLLUTANTS OF WATER BODY AND METHOD FOR USING SAME
Document Type and Number:
WIPO Patent Application WO/2022/134372
Kind Code:
A1
Abstract:
A device for detecting the concentration of concentrated pollutants in a water body, comprising a floating body (100), a current stabilizer (200), guide rails (300) and a detection piece (400). The floating body (100) is a hollow cylindrical structure, and the detection piece (400) is a square-shaped filter screen. The surface of the floating body (100) is connected by means of a tripod-shaped bracket (110) so as to facilitate the placement and lifting of the floating body (100). An inner cavity of the floating body (100) is connected to several symmetrical guide rails (300), and the guide rails (300) are vertically arranged. A sliding block (310) is provided on each guide rail (300), and the sliding blocks (310) and clamps (330) are connected by means of retractors (320). The sliding blocks (310) drive the detection piece (400) to move along the vertical direction. A top layer of the detection piece (400) is a circular groove (410), and each layer of the detection piece (400) except for the top layer is equiangularly distributed with several chromatography grooves (420). The chromatography grooves (420) are enlarged in sequence from top to bottom. Each layer of grooves of the detection piece (400) is communicatively arranged and form several trapezoidal structures that spread from the center to the periphery. Each layer of grooves of the detection piece (400) is adhered with a detection test paper (430) of a matching size. In the detection device, the current stabilizer (200) is used to create a relatively stable water layer inside of the floating body (100). The detection test paper (430) performs gradient adsorption, and the detection result is more accurate.
