Referring to fig. 2 and 4, in this embodiment, in order to prevent the sliding block 181 from being separated from the sliding groove 18 in a direction perpendicular to the length direction of the sliding groove 18, the cross section of the sliding groove 18 is formed in a "T" shape, and the sliding block 181 is disposed to be engaged with the sliding groove 18 in the "T" shape.

When the first water outlet bent pipe 161 needs to be fixed to the support 17, the second handle 184 drives the bidirectional screw 183 to rotate in the chute 18, and the chute 18 prevents the slider 181 from rotating along with the rotation of the bidirectional screw 183, so that the sliders 181 on the two sides move on the bidirectional screw 183, the sliders 181 on the two sides drive the abutting plates 182 to approach or separate from each other, the sliders 181 on the two sides drive the abutting plates 182 to clamp the first water outlet pipe 16 and the second water outlet pipe 162, and the first water outlet pipe 16 and the second water outlet pipe 162 are fixed to the support 17; the fixing of the water inlet pipe and the water outlet pipe at the two ends of the siphon pipe 14 can be completed by rotating the second handle 184, which is convenient and simple.

The implementation principle of the embodiment is as follows: when the water level in the upstream area 12 is higher than the level of the end of the second inlet pipe 145, by opening the valve 142 and the suction pump 141 of the siphon tube 14, at this time, the suction pump 141 draws the siphon tube 14 to a water-filled vacuum state, since the height of the end of the second inlet pipe 145 is higher than the height of the end of the hose 164, such that the pressure at the inlet end 146 is greater than the pressure at the outlet end 147, such that water in the upstream region 12 can be automatically drawn through the siphon tube 14, through the siphon 14, into the outlet pipe, through the outlet pipe into the flare 163, so that the velocity of the water flow is slowed, now through flare 163 into hose 164, and is discharged through the hose 164, reducing the difference in height between the water flow in the upstream region 12 and the bottom wall of the waterway 1, thereby reducing the height difference of the water flow when the water flow is leaked into the downstream area 13, greatly reducing the noise and improving the life quality of residents; when the water surface height in the upstream area 12 is lower than the height of the end part of the second water inlet pipe 145, the water outlet pipe is integrally arranged in a U shape, so that the water outlet pipe always keeps a water filling state, the siphon pipe 14 always keeps the water filling state, and when the water surface height in the upstream area 12 is higher than the height of the end part of the second water inlet pipe 145 again, water flow can automatically enter the siphon pipe 14 through the water inlet pipe, siphon discharge is automatically completed, and the suction pump 141 does not need to be opened again.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
