It should be noted that the cylindrical rod 21 is arranged at the bottom of the rotating plate 20, the annular sliding groove 23 is formed in the top of the U-shaped block 16, the cylindrical rod 21 slides in the annular sliding groove 23, the annular sliding groove 23 is an arc groove, the radius of the rotating shaft 19 is the same as the length of the rotating plate 20, the groove width of the annular sliding groove 23 is the same as the diameter of the cylindrical rod 21, and the rotating plate 20 can drive the cylindrical rod 21 to stably slide in the annular sliding groove 23.

The tangent to the end of the annular chute 23 adjacent the support platform 17 is parallel to the axis of the spring receiving hole 24, which ensures that when the pivotal plate 20 carries the cylindrical rod 21 to the end of the annular chute 23, the U-shaped block 16 is moved away from the support platform 17 and is no longer affected by the cylindrical rod 21.

The limiting block 22 is arranged on the side edge of the U-shaped block 16, and the limiting block 22 is flush with the highest point of the inner annular wall of the annular sliding groove 23, so that the U-shaped block 16 is limited by the cylindrical rod 21 and the limiting block 22 on a mutually separated path when being away from the supporting table 17, the U-shaped block 16 and the supporting table 17 cannot be separated under the condition that the water flow impact plate 18 is impacted by water flow, and meanwhile, the telescopic pipe wall 2 cannot slide on the L-shaped bent water pipe 1 when the valve is not closed, and water in the L-shaped bent water pipe 1 cannot flow into the water storage tank 3;

when the valve is closed, because of the delay, the water flow of the L-shaped bent water pipe 1 near the position limiting device 27 stops flowing, and the following water still flows and impacts the telescopic pipe wall 2 on the side wall of the L-shaped bent water pipe 1, it should be noted that, at this time, the water flow impact plate 18 has no impact of the water flow, the rotating plate 20 drives the rotating plate 20 to rotate around the limiting block 22 under the action of the return spring 26, and the cylindrical rod 21 at the end of the rotating plate 20 slides in the annular sliding groove 23, so when the U-shaped block 16 and the supporting table 17 are separated, the limiting block 22 does not have a limiting effect on the rotating plate 20.

The working principle of the invention is as follows: firstly, flowing water exists in the L-shaped bent water pipe 1, the water flow direction is from right to left, when the valve is not closed, the flowing water flow can impact the side wall of the bent part of the L-shaped bent water pipe 1, at the moment, the water flow at the position of the limiting device 27 still flows, turbulent water flow can impact the water flow impact plate 18, the rotating water flow impact plate 18 drives the rotating plate 20 to rotate around the rotating shaft 19, the reset spring 26 is the longest stretching length, at the moment, the cylindrical rod 21 at the bottom surface of the end part of the rotating plate 20 is positioned above the limiting block 22, it needs to be noted that the limiting block 22 is flush with the highest point of the inner ring wall of the annular sliding groove 23, the purpose of the design is that when the U-shaped block 16 is far away from the supporting table 17, the U-shaped block 16 can be limited by the cylindrical rod 21 and the limiting block 22 on mutually separated paths, and under the condition that the water, therefore, when the valve is not closed, even if water impacts the telescopic pipe wall 2 at the bent part of the L-shaped bent water pipe 1, the telescopic pipe wall 2 is close to the end of the limiting device 27 and cannot move, so that the long hole plate 7 and the second supporting rod 10 cannot slide in the sliding cylinder 5, and meanwhile, the pushing block 8 on the impact plate 6 cannot displace on the long hole plate 7 due to the fact that the position of the long hole plate 7 is not moved, as shown in fig. 5, the impact plate 6 and the long hole plate 7 cannot displace, so that when the valve is not closed, the telescopic pipe wall 2 cannot slide on the L-shaped bent water pipe 1, and water in the L-shaped bent water pipe 1 cannot flow into the water storage tank 3.

Then, when the valve is closed, because of the delay, the water flow of the L-shaped bent water pipe 1 near the position limiting device 27 stops flowing, and the following water still flows and impacts the telescopic pipe wall 2 on the side wall of the L-shaped bent water pipe 1, it should be noted that, at this time, the water flow impact plate 18 has no impact of the water flow, the rotating plate 20 drives the rotating plate 20 to rotate around the limiting block 22 under the action of the return spring 26, and the cylindrical rod 21 at the end of the rotating plate 20 slides in the annular sliding groove 23, so when the U-shaped block 16 and the supporting table 17 are separated, the limiting block 22 does not have a limiting effect on the rotating plate 20.

It should be noted that the annular sliding groove 23 is a circular arc groove with the radius of the rotating shaft 19 being the length of the rotating plate 20, and the width of the annular sliding groove 23 is the same as the diameter of the cylindrical rod 21, so that the rotating plate 20 can drive the cylindrical rod 21 to stably slide in the annular sliding groove 23.

At this time, water in the L-shaped bent water pipe 1 impacts the telescopic pipe wall 2 again, so that the telescopic pipe wall 2 slides in the L-shaped bent water pipe 1, the right end of the telescopic pipe wall 2 is impacted by water flow at first, the telescopic pipe wall 2 extrudes the impact plate 6, and the impact plate 6 drives the first support rod 9 to slide in the fixed cylinder 4 at this time, it needs to be explained that the pushing block 8 on the impact plate 6 slides in the long hole plate 7 at this time, it can be known through force decomposition that the acting force of the impact plate 6 on the long hole plate 7 can be decomposed into two directions along the long hole plate 7 and perpendicular to the long hole plate 7, and the force along the direction of the long hole plate 7 can act on the telescopic pipe wall 2, so that two ends of the telescopic pipe wall 2 can be stressed, and the telescopic pipe wall 2 can stably slide on the L-shaped bent; the force along the direction vertical to the long hole plate 7 can slide on the slide rail 14 through the T-shaped slide block 13 on the slide cylinder 5, so that the water in the L-shaped bent water pipe 1 flows into the water storage tank 3 from the gap generated by the telescopic pipe wall 2 and the L-shaped bent water pipe 1, the water on the telescopic pipe wall 2 is prevented from being impacted, and the bent part of the L-shaped bent water pipe 1 is damaged.
