And step three, the controller sends a signal to the internal pressure control mechanism 6, and the internal pressure control mechanism 6 increases the internal pressure of the spherical water sample collection box 3 after receiving the signal, so that the internal and external pressure difference of the spherical water sample collection box 3 reaches a smaller value, and the spherical water sample collection box 3 is opened conveniently.
And step four, the controller sends a signal to the spherical water sample collection box 3, and the spherical water sample collection box 3 releases the sealing state after receiving the signal, so that water enters the spherical water sample collection box 3 and fills the spherical water sample collection box with the water.
And step five, the controller sends a signal to the spherical water sample collection box 3, and the spherical water sample collection box 3 is closed after receiving the signal, so that the internal environment is isolated from the external water body.
And step six, the controller sends a signal to the detector 4, the detector 4 detects the water body sample in the spherical water sample collection box 3 after receiving the signal, and whether the water quality meets the culture standard is judged according to the type and the quantity of microorganisms in the sample.
And seventhly, after the detection is finished, the controller sends a signal to the spherical water sample collection box 3, and the spherical water sample collection box 3 is opened again after receiving the signal.
And step eight, the controller sends a signal to the internal pressure control mechanism 6, the internal pressure control mechanism 6 pressurizes the inside of the spherical water sample collection box 3 again after receiving the signal, so that the water in the inside is discharged, and then the controller closes the spherical water sample collection box 3. The gravity of the spherical water sample collection box 3 is reduced, so that the spherical water sample collection box can float upwards more conveniently.
Step nine, the controller sends a signal to the paying-off mechanism 1, and the paying-off mechanism 1 lifts the spherical water sample collection box 3 and the mounting box 5 through the cable 2 after receiving the signal.
