[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: A riverbank protection device includes a slope protection body 1, the top right side of the slope protection body 1 is set as an inclined surface, and a flower and grass planting area 2 is provided on the inclined surface of the slope protection body 1, such as... Figure 1 The top left side of the slope protection body 1 is provided with an installation plate 3, and a vertical pipe 4 is vertically provided on the installation plate 3. The installation plate 3 is provided with a pumping device for pumping river water into the vertical pipe 4. The installation plate 3 is provided with a water spraying device connected to the vertical pipe 4, and the water spraying device is used to spray water upwards towards the flower and grass planting area 2.

[0033] like Figure 1 In use, river water is pumped to vertical pipe 4 via a pumping unit. The water then enters the spray nozzle from vertical pipe 4 and sprays outwards towards the flower and grass planting area 2. The sprayed water drips down into the flower and grass planting area 2 due to gravity, thus mimicking rain. This facilitates watering the flowers and grass in the planting area 2 and reduces the occurrence of washing away the flowers and grass or stirring up the soil. At the same time, it does not affect the sunlight reaching the flowers and grass. By spraying water upwards towards the flower and grass planting area 2 through nozzle 9, water can be irrigated while simultaneously reducing dust in the air, thus improving the air quality around the slope protection device.

[0034] The slope protection body 1 may be the slope protection body in the river slope protection device and slope protection method for water ecological restoration in application number CN201911372271.9, which will not be described in detail here.

[0035] like Figure 1 and Figure 2The water spraying device includes a middle pipe 5 inclined at the top of the vertical pipe 4, with the top of the middle pipe 5 tilted towards the inclined surface of the slope protection body 1. The top of the middle pipe 5 is connected to a rotating pipe 6, and the end of the rotating pipe 6 away from the middle pipe 5 is connected to an arc-shaped pipe 7. The end of the arc-shaped pipe 7 away from the rotating pipe 6 is connected to an L-shaped conduit 8. The end of the conduit 8 away from the arc-shaped pipe 7 faces upward and is equipped with a nozzle 9. The purpose of this arrangement is that river water passes through the middle pipe 5, rotating pipe 6, arc-shaped pipe 7, and conduit 8 sequentially from the vertical pipe 4 into the nozzle 9, and then sprays out upward from the nozzle 9. Because the middle pipe 5 is inclined, the nozzle 9 can spray water upward towards the flower and grass planting area 2, so as to simulate rain to irrigate the flowers and grass in the flower and grass planting area 2. It is simple and convenient to use.

[0036] like Figure 1 and Figure 2 and Figure 3 The rotating pipe 6 is rotatably connected to the intermediate pipe 5. When the pumping unit is working, the water flows through the intermediate pipe 5 and the rotating pipe 6. The rotating pipe 6 is equipped with a rotating component to drive the rotating pipe 6 to rotate. The purpose of this setting is that when the water passes through the intermediate pipe 5, the rotating pipe 6, the arc-shaped pipe 7, the guide pipe 8 and then sprays out from the nozzle 9, the water flow through the intermediate pipe 5 and the rotating pipe 6 will drive the rotating pipe 6 to rotate through the rotating component. At this time, the arc-shaped pipe 7, the guide pipe 8 and the nozzle 9 will rotate with the rotating pipe 6, which can increase the spraying range of the nozzle 9. It is simple and convenient to use.

[0037] like Figure 3 and Figure 4 and Figure 5 The rotating component includes a horizontal plate 10 disposed between opposite sides inside the rotating pipe 6. A central shaft 12 located inside the intermediate pipe 5 is fixedly connected to the side of the horizontal plate 10 closest to the intermediate pipe 5. The central shaft 12 is coaxial with the rotating pipe 6. Several blades 13 are inclinedly disposed on the central shaft 12, and each blade 13 is evenly distributed along the axis of the central shaft 12. The purpose of this arrangement is that the water flow through the intermediate pipe 5 and the rotating pipe 6 can drive the central shaft 12 to rotate through the inclined blades 13. At this time, the central shaft 12 will drive the rotating pipe 6 to rotate on the intermediate pipe 5 through the horizontal plate 10. It is simple and convenient to use.

[0038] like Figure 3 and Figure 4 and Figure 6The top of the mounting plate 3 has two opposing vertical plates 14. The intermediate tube 5 and the vertical plate are both located between the two vertical plates 14. The intermediate tube 5 includes a flexible tube 15 and a transition tube 16 connected to the flexible tube 15. The end of the flexible tube 15 away from the transition tube 16 is connected to the vertical tube 4. The rotating tube 6 is rotatably connected to the end of the transition tube 16 away from the flexible tube 15. The central shaft 12 is located inside the transition tube 16 and is coaxial with the transition tube 16. The outer walls of the opposite sides of the transition tube 16 are horizontally provided with rotating shafts 17, and the two rotating shafts 17 are rotatably connected to the two vertical plates 14 respectively. When the rotating tube 6 rotates, the guide tube 8 is provided with a... The power component that drives the transition pipe 16 to rotate along the axis of the rotating shaft 17 includes a counterweight 18 disposed on the side of the guide pipe 8 away from the arc-shaped pipe 7. The guide pipe 8, the nozzle 9, and the counterweight 18 are all located on the left side above the rotating shaft 17. Both upright plates 14 are provided with limiting components for limiting the rotation angle of the rotating shaft 17. The limiting components include a ring 19 disposed on the side of the upright plate 14 near the rotating shaft 17. The rotating shaft 17 and the ring 19 are coaxial. The rotating shaft 17 is provided with a swing plate 20 located inside the ring 19. Two baffles 21 are provided on the inner side wall of the ring 19. The swing plate 20 is located between the two baffles 21.

[0039] like Figure 3 and Figure 4 and Figure 6 When the rotating pipe 6 rotates, the arc-shaped pipe 7, the guide pipe 8, the nozzle 9, and the counterweight 18 will rotate with the rotating pipe 6. As the rotating pipe 6 rotates on the transition pipe 16, when the guide pipe 8, the nozzle 9, and the counterweight 18 rotate to the upper right side of the rotating shaft 17, the guide pipe 8, the nozzle 9, and the counterweight 18 will be affected by gravity, and through the arc-shaped pipe 7 and the rotating pipe 6, they will drive the transition pipe 16 to rotate along the axis of the rotating shaft 17. At this time, the transition pipe 16 will drive the rotating shaft 17 to rotate on the vertical plate 14, which can further increase the spraying range of the nozzle 9. When the rotating shaft 17 rotates, the swing plate 20 will rotate with the rotating shaft 17. At this time, because the swing plate 20 is positioned... Between the two baffles 21, the rotation angle of the rotating shaft 17 can be limited by the swing plate 20 and the two baffles 21. When the rotating tube 6 rotates on the transition tube 16, the guide tube 8, the nozzle 9 and the counterweight 18 rotate to the upper left side of the rotating shaft 17. The guide tube 8, the nozzle 9 and the counterweight 18 will be affected by gravity. Through the arc tube 7 and the rotating tube 6, the transition tube 16 will rotate in the opposite direction along the axis of the rotating shaft 17. The rotation angle of the rotating shaft 17 is 10 degrees. Through the above process, the nozzle 9 can swing along the axis of rotation of the rotating tube 6 while rotating along the axis of rotation of the rotating shaft 17.

[0040] like Figure 2A threaded cylinder 22 is coaxially provided on the outer wall of the conduit 8 near the nozzle 9, and a protective barrel 23 is coaxially threaded on the outer wall of the threaded cylinder 22. The nozzle 9 is located inside the protective barrel 23. The purpose of this setting is to protect the nozzle 9 through the protective barrel 23, reducing the possibility of accidental contact with the nozzle 9 by unauthorized personnel or children, which could cause damage to the nozzle 9. When the nozzle 9 is working, the protective barrel 23 should be unscrewed from the threaded cylinder 22 first.

[0041] like Figure 2 The pumping unit includes a support plate 24 vertically mounted on the top of the mounting plate 3 and a pump 25 mounted on the vertical pipe 4. The pump 25 is fixedly mounted to the support plate 24. The bottom end of the vertical pipe 4 is connected to a pumping pipe 26 for drawing river water. The pumping pipe 26 is L-shaped. The purpose of this setting is that when the pump 25 is turned on, the river water can be drawn into the vertical pipe 4 through the cooperation of the pump 25 and the pumping pipe 26. The end of the pumping pipe 26 located in the river water is equipped with a filter bucket 27 for filtering the river water. It is simple and convenient to use.

[0042] Example 2: A slope protection method according to Example 1 above: When in use, the river water is pumped to the vertical pipe 4 through the pumping device, and then the river water enters the water spraying device from the vertical pipe 4 and sprays out from the water spraying device towards the top of the flower and grass planting area 2. The sprayed water drips down to the flower and grass planting area 2 due to gravity, which can simulate rain to irrigate the flowers and grass in the flower and grass planting area 2.

[0043] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
