128 and 129 does not block the water inlet hole 125 and the water outlet hole 126, the up-and-down movement of the first and second regulation cones 128 and 129 only regulates the opening sizes of the water inlet hole 125 and the water outlet hole 126, therefore, the opening sizes of the water inlet hole 125 and the water outlet hole 126 can be controlled by the up-and-down movement of the first and second regulation cones 128 and 129, and when the surface runoff flows into the water inlet pipe body 1, the surface runoff flow is large, the downward movement distance of the water inlet plate

cone 128 moves down, since the first adjusting cone 128 moves from top to bottom and the smallest diameter end is downward, the first adjusting cone 128 moves downwards to enable the opening of the water inlet hole 125 to be smaller, the second adjusting cone 129 is inserted from bottom to top, the minimum diameter end is upwards, the second adjusting cone 129 moves downwards to enable the opening of the water outlet hole 126 to be larger, the opening of the water inlet hole 125 is reduced through the functions of the first adjusting cone 128 and the second adjusting cone 129, the purposes of reducing the cross section area and increasing the flow rate are achieved, the water inlet quantity at the water inlet hole 125 and the water inlet quantity in a normal state reach an equilibrium state, meanwhile, the water outlet hole 126 becomes larger, and excessive water is discharged in a large quantity through the water outlet hole 126, so that the water inlet quantity

body 1 is smaller, the water impact force is smaller on the lower pressure of the water inlet plate 122, therefore, the water inlet plate 122 moves upwards compared with the water inlet plate in the normal state, the opening of the water inlet hole 125 becomes larger, and the opening of the water outlet hole 126 becomes smaller, so that a large amount of water sample enters the connecting pipe 14 through the water inlet hole 125, the opening of the water inlet hole 125 is enlarged when the water inlet amount is smaller, the water inlet amount at the connecting pipe 14 is balanced with the water inlet amount in a normal state, therefore, through the adjustment of the opening size of the water inlet hole 125 and the arrangement of the water inlet plate 122 according to the surface runoff flow amount, the water inlet pipe body 1 can be automatically controlled according to the surface runoff flow amount when the water is discharged into the sampling box 2, the water inlet amount at the sampling box 2 can reach an equilibrium state when the surface runoff flow amount is large or small, the influence of the surface runoff flow amount on the water inlet amount at the sampling box 2 is

surface runoff flows into the water inlet pipe body 1, under the normal condition of water inflow, the water entering the water inlet pipe body 1 presses down the water inlet plate 122, the water inlet plate 122 enables the first regulating cone 128 to move downwards, the opening of the water inlet hole 125 reaches the normal size due to the fact that the first regulating cone 128 moves downwards from top to bottom and the minimum diameter end faces downwards, the second regulating cone 129 is inserted from bottom to top and the minimum diameter end faces upwards, the second regulating cone 129 moves downwards to enable the opening of the water outlet hole 126 to reach the normal size, a water sample enters through the opening of the water inlet hole 125 and enters the sampling box 2 through the connecting pipe 14, the redundant water is discharged through the water outlet hole 126 at the same time, and when the water inflow is increased, when the water amount is large, the water inlet plate 122 is pressed down by a large impact force, the water inlet plate 122 is pressed down to enable the connecting column 127 to drive the first adjusting cone 128 to move down, when the first adjusting cone 128 moves down, the water inlet hole 125 opening is reduced due to the fact that the first adjusting cone 128 moves down from top to bottom and the minimum diameter end is downward, meanwhile, the second adjusting cone 129 is inserted from bottom to top, and the minimum diameter end is upward, the water outlet hole 126 opening is enlarged due to the fact that the

reduced, the flow speed is increased, the water inlet amount at the water inlet hole 125 and the water inlet amount in a normal state are balanced state, meanwhile, the water outlet hole 126 is enlarged, and excessive water is discharged through the water outlet hole 126 in a large amount, therefore, so that the water quantity entering the water inlet 125 and the water quantity entering the water inlet under the normal state reach an equilibrium state, when the water quantity is smaller, the impact force of the water body entering the water inlet pipe body 1 is smaller, the downward pressure of the impact force of the water body to the water inlet plate 122 is smaller, therefore, the water inlet plate 122 moves upwards, compared with the water inlet 125 which is larger in opening and the water outlet 126 which is smaller in opening under the normal state, a large amount of water sample enters the connecting pipe 14 through the water inlet 125, so that the water inlet 125 is enlarged when the water quantity is smaller, the water quantity at the connecting pipe 14 and the water quantity entering the water inlet under the normal state reach equilibrium, so that the water quantity at the sampling box 2 can reach an equilibrium state when the surface runoff flow is large or the water quantity is small, and then when the water sample enters the sampling box 2 through the connecting pipe 14, the water discharged at the connecting pipe 14 can directly fall on the blades 52, so that the rotating wheel 51 rotates, the collecting box 54 rotating along with the blades 52 rotates below the opening of the connecting pipe 14, the water discharged from the connecting pipe 14 enters the collecting box 54, meanwhile, the rotating wheel 51 continues to rotate, so that the collecting box 54 rotates above the sampling bottle 3, and when the collecting box 54 rotates above the sampling bottle 3, the collecting box 54 is far away from the water outlet 7 of the connecting pipe 14, so that the water discharged from the connecting pipe 14 cannot enter the collecting box 54 any more, so that when the rotating wheel 51 continues to rotate, the water can be intermittently collected through the collecting box 54 rotating along with the rotating wheel 51, and the water which is not collected by the collecting box 54 and is discharged through the water outlet 7 when the connecting pipe 14 rotates above the sampling bottle 3, the trigger plate 16 is positioned below the trigger rod 15 due to the fact that the rotating wheel 51 continues to rotate, and the collecting box 54 rotates to be arranged inside the yielding groove 53, thereby trigger plate 16 can contact with trigger lever 15, through the conflict of trigger lever 15, can make collection box 54 rotate the
