A connecting ring 14 is fixedly installed in the detection cylinder 1, and a first liquid one-way valve 15 is embedded in the connecting ring 14. The first liquid one-way valve 15 is provided to enable the liquid to only enter the detection cylinder 1 unidirectionally during sampling.

[0023] A liquid extraction mechanism is fixedly installed on the side wall of the detection cylinder 1. The liquid extraction mechanism includes an arc-shaped bracket 2, which is fixedly installed on the outer side wall of the detection cylinder 1.

By providing the support ring 10, the piston block 6 can be prevented from directly contacting the liquid suction pipe 7, which not only improves the sealing performance of the piston block 6 but also reduces the degree of wear on it. A control switch 5 is fixedly installed on the side wall of the arc-shaped bracket 2, and the control switch 5 is electrically connected to the electric hydraulic rod 4.

A second liquid one-way valve 8 is fixedly installed on the side wall of the liquid discharge pipe 9. When it is necessary to take a sample again, the electric hydraulic rod 4 is controlled to move in the reverse direction, so that the water sample in the detection cylinder 1 is squeezed out through the liquid discharge pipe 9 and the second liquid one-way valve 8 by using the piston block 6, so that cyclic sampling detection can be carried out.

[0025] A detection and analysis mechanism is arranged on the side wall of the detection cylinder 1.

Then, observe and analyze the water sample through the transparent detection box 11 and with the help of the provided water quality detector 12. When it is necessary to take a sample again, control the electric hydraulic rod 4 to move in the reverse direction, so that the piston block 6 is driven to move by the electric hydraulic rod 4. The piston block 6 squeezes out the water sample in the detection cylinder 1 through the liquid discharge pipe 9 and the second liquid one-way valve 8, and then clean water can be inhaled again to wash the equipment, so that cyclic sampling detection can be carried out.
