During the process, the direction of the impact of the high-speed water flow will change. After the water flow leaves the first water raising plate 17, part of it falls freely, and part enters the second water raising plate 15. The direction of the water flow and the direction of the water flow impact change again. After the water flow changes direction twice, the water flow speed decreases. The decelerated water flow will pass through the upper inclined water diversion plate 12 and the lower inclined water diversion plate 12 in sequence, and at the end of the two inclined water diversion plates 12 The water changes direction at the end and slows down.

[0026] like Figure 2 、 Figure 3 and Figure 5As shown, the vertical box 1 is fixed with a U-shaped plate 14 below the first water-raising plate 17; the U-shaped plate 14 is arranged at the position corresponding to the two inclined water-dividing plates 12; the bottom of the vertical box 1 is fixed with an impact block 16; the impact block 16 is arranged corresponding to the output end of the first water-raising plate 17 and the second water-raising plate 15; when working, the water flow is guided by the first water-raising plate 17 and the vertical downward movement is converted to an inclined upward movement, and then it will mainly impact the groove at the bottom of the impact block 16.

During operation, when water flows through the upper inclined water diversion plate 12, a part of the water will fall onto the surface of the horizontal water diversion plate 13 through the leakage grooves of the upper inclined water diversion plate 12. The water falling on the surface of the horizontal water diversion plate 13 overflows to both sides, and a part falls onto the surface of the lower inclined water diversion plate 12 through the leakage grooves of the horizontal water diversion plate 13. The water turned by the U-shaped plate 14 comes to the water of the lower inclined water diversion plate 12, and the water falling from above, a part continues to move along the direction of the inclined water diversion plate 12, and a part falls from the leakage grooves of the lower inclined water diversion plate 12. During the process, the main water flow is divided into two parts, one part follows the operation of the components of the device, and the other part falls freely. This project disperses the main water flow, reduces the energy dissipation pressure, and improves the water efficiency effect.

With the guidance of the first water-raising plate 17, the direction of the water flow changes. In the process, the direction of the impulse of the high-speed water flow will change. After the water flow leaves the first water-raising plate 17, part of it falls freely, and part enters the second water-raising plate 15. The direction of the water flow and the direction of the water flow impulse change again. After the water flow changes direction twice, the water flow speed decreases. The decelerated water flow will pass through the upper inclined water diversion plate 12 and the lower inclined water diversion plate 12 in turn, and change direction at the end of the two inclined water diversion plates 12, decelerating.

The water flow is guided by the first water-raising plate 17 and the vertical downward movement is converted to an inclined upward movement. Then it will mainly impact the groove at the bottom of the impact block 16. In the process, the impact force will be digested and the water flow speed will be reduced. After the water flow hits the impact block 16, it will mainly fall to the second water-raising plate 15 and change direction. It will hit the impact block 16 again and slow down here. After passing through the upper inclined water diversion plate 12, the water flow will hit the U-shaped plate 14, change direction, and then mainly flow through the inclined water diversion plate 12. The water flow passes through the upper layer. When the water diverter plate 12 is tilted, part of the water will fall through the trough of the upper inclined water diverter plate 12 to the surface of the horizontal water diverter plate 13. The water falling on the surface of the horizontal water diverter plate 13 overflows to both sides, and part of it falls through the trough of the horizontal water diverter plate 13 to the surface of the lower inclined water diverter plate 12. The water diverted by the U-shaped plate 14 comes to the water of the lower inclined water diverter plate 12, and the water falling from above, part of it continues to move along the direction of the inclined water diverter plate 12, and part of it falls from the trough of the lower inclined water diverter plate 12; in the process, the main water flow is divided into two parts, one part follows the operation of the components of the device, and the other part falls freely. The limit block 11 increases the leakage plate 10 The side area increases the fixing strength. The upper water body falls on the surface of the leak plate 10 one after another, and forms a water column by the leak holes on the surface of the leak plate 10, and finally converges on the top of the bottom plate 6. In the process, the water body falling on the surface of the leak plate 10 will further reduce the speed to prevent the water flow from rushing to the bottom. The four support columns 7 connect the various components so that the force of various parts of the device can be transmitted to prevent the first water lifting plate 17 or the second water lifting plate 15 from being overstressed and falling off. The device can be fixed with bolts to prevent the device from being moved or tipped over during operation. The suction pipe 4 can be installed on the top of the protective pipe 3 to prevent the impact caused by the turning of the water body from damaging the suction pipe 4.
