s1, moving a measuring main body (1) to the position right above a collection point, and preliminarily adjusting the distance between a collection head (24) and the collection point through a telescopic supporting leg (10);
s2, starting a rotating motor (21) through a controller (40), driving a rolling roller (20) to rotate along a pointer through the rotating motor (21), at the moment, winding a connecting hose (22) on the rolling roller (20) down from the rolling roller (20), and under the action of gravity, enabling the rolling roller (20) to downwards stretch a telescopic frame (200), enabling a collecting head (24) to downwards slide under the action of gravity, pushing a mounting bracket (23) to synchronously downwards slide along the inner wall of a telescopic supporting leg (10), and finely adjusting the downwards sliding position of the collecting head (24);
s3, after the position of the collecting head (24) is regulated, a micro water suction pump (242) is started through a controller (40), flowing water is filtered by a filtering net cover (241) and enters a tee joint through an inverted T-shaped hollow mounting cylinder (240) and a connecting hose (22), then a first electromagnetic valve (14) at a water pipe (13) connected with an adding port (11) is opened, the collected water enters a liquid separation disc (110) and flows into a corresponding detection cavity (35) through each liquid separation port (111), meanwhile, the total water inflow into a detection dispersion disc (30) is detected through an electronic flowmeter (41), and after the preset requirement is met, the first electromagnetic valve (14) is closed, and the water quality of water flow in a corresponding detection cavity (35) is detected through a water quality detection sensor (33);
s4, after the first water quality measurement is finished, opening a first electromagnetic valve (14) and a second electromagnetic valve (3230) at the joint of the tee joint and the discharge port (12) through a controller (40), enabling the water body in the detection cavity (35) to flow into the measurement main body (1) through the L-shaped bleeder pipe (321), and enabling the water body to flow into the flowing water body again through the water pipe (13), the connecting hose (22) and the collection head (24), and repeating the step S3 for a plurality of times to finish the repeated collection and measurement of the flowing water quality;
s5, after each time of water quality measurement, the water quality detection sensor (33) sends a detection result to the controller (40), then the controller (40) controls the report generation module (43) to generate a water quality detection report on the detection result, and finally the controller (40) drives the rolling roller (20) to rotate against the pointer, so that the connecting hose (22) positioned at the lower end of the rolling roller (20) is rewound on the rolling roller (20), and the connecting hose (22) is rewound on the rolling roller (20) to enable the acquisition head (24) to move upwards.
