10. A water quality environment detection method applied to the water quality environment detection system according to any one of claims 1 to 9, the detection method comprising the steps of:

step two, detecting the system start: the working personnel start the timing driving device to enable the sealing plate (6) to move upwards in a timing mode to seal the water passing bin (2), the sampling communicating device is started while the water passing bin (2) is sealed, so that a water sample in the water passing bin (2) is communicated and collected into the sampling box (4), and the water sample is collected;

step three, detecting the flow velocity of water flow: when the timing driving device is started regularly, the current water flow speed is detected and recorded by a flow speed detector (12);

step four, water flow timing sampling: after the sampling of a water sample is finished, the timing driving device drives the sealing plate (6) to move downwards to expose the water passing bin (2), so that water flows through the water passing bin (2) to take away residual water samples, and the water flows continuously to pass through until the timing driving device is started to sample at the next time.
