A through groove is provided at the top of the outer filter cover 1, and the inner filter cover 2 is fixedly connected to the inside of the through groove. A circular hole is provided on the top of the inner filter cover 2, and a water outlet pipe 3 is fixedly connected to the inside of the circular hole. The water outlet pipe 3 is connected to a water pump to suction and sample the surface water, and is provided with a sample storage tank, a monitoring mechanism, etc. (not shown in the figure) to perform real-time online sampling and detection on the sucked surface water. The monitoring mechanism includes a turbidity meter, etc., which can be adjusted according to specific usage conditions. The surface water quality monitoring mechanism is an existing common technology and will not be described here.

[0021] The outer filter cover 1 is provided with a plurality of outer filter holes 18, and the inner filter cover 2 is provided with a plurality of inner filter holes 19. The inner diameter of the inner filter holes 19 is smaller than the inner diameter of the outer filter holes 18. The outer filter cover 1 filters large particles of impurities, and the inner filter cover 2 filters small particles of impurities.

[0022] During the filtration process, large impurities adhere to outer filter cover 1 due to suction, while small impurities adhere to inner filter cover 2 due to suction. To prevent clogging of outer filter holes 18 and inner filter holes 19, improve sampling efficiency, and ensure the effectiveness of online monitoring, a connecting rod 16 is fixedly connected to the bottom of inner filter cover 2, and connecting rod 16 is fixedly connected to outer filter cover 1. An annular slide 4 is provided at the top of outer filter cover 1, and annular slide 4 surrounds the outside of inner filter cover 2.
