When the water collection channel 9 passes through the column, the water collection channel 9 swings outward, and when opened, it can be swung and guided by the arc-shaped guide rail 47 and the universal wheel 49.
[0046] The filter layer 14 includes a lower filter screen laid on the top surface of the grid, and the top surface of the lower filter screen is filled with activated carbon filler and gravel filler in sequence; an upper filter screen is laid on the top of the gravel filler; when the cleaned water is collected in the water collection channel 9, the water flows through the upper filter screen, gravel filler, activated carbon filler and lower filter screen in sequence, thereby filtering the collected cleaning water.
[0047] The elastic module 10 includes an elastic column 50 that can be movably passed through the hinged frame 3, and the elastic column 50 is externally screwed with a limiting nut, and the inner side of the elastic column 50 is fixed to the laminating roller 51; the laminating roller 51 is in contact with the outside of the water collection channel 9; the elastic column 50 is provided with an inner spring 52 between the pressure roller 45 and the hinged frame 3; when in use, the laminating roller 51 is pressed against the outer surface of the water collection channel 9 by the inner spring 52, so that the two groups of water collection channels 9 are pressed against each other, so that the two groups of water collection channels 9 enter under the guardrail board of the guardrail, and can fully recover the cleaning water. When the water collection channel 9 passes through the guardrail column, the guide roller 11 contacts the surface of the column, thereby expanding the water collection channel 9 outward; so that the guide roller 11 can smoothly pass through the guardrail column, so that the two groups of water collection channels 9 can not only smoothly pass through the guardrail column, but also enable the water collection channel 9 to collect the guardrail cleaning water.
