[0023] like Figure 1 When in use, the river water is pumped to the vertical pipe 4 through the pumping part, and then the river water enters the water spraying part from the vertical pipe 4, and is sprayed from the water spraying part toward the top of the flower and grass planting area 2. The sprayed water drops to the flower and grass planting area 2 under the influence of gravity, and then it can imitate rain, which is convenient for watering the flowers and plants in the flower and grass planting area 2, and reduces the occurrence of flowers and plants being washed down and soil being washed up, and at the same time will not affect the sunlight exposure to the flowers and plants. Water is sprayed toward the top of the flower and grass planting area 2 through the nozzle 9, so as to imitate rain to water the flowers and plants in the flower and grass planting area 2, and at the same time, dust in the air can be reduced, thereby improving the air quality around the slope protection device.

[0024] The slope protection body 1 can be a slope protection body in a river slope protection device and slope protection method for water ecological restoration with application number CN201911372271.9, which will not be described in detail in this application.

[0025] like Figure 1 and Figure 2The water spraying part includes an intermediate tube 5 obliquely arranged at the top of the vertical tube 4, and the top of the intermediate tube 5 is inclined to the side close to the inclined surface of the slope protection body 1, the top of the intermediate tube 5 is connected with a rotating tube 6, and the end of the rotating tube 6 away from the intermediate tube 5 is connected with an arc tube 7, and the end of the arc tube 7 away from the rotating tube 6 is connected with an L-shaped conduit 8, and the end of the conduit 8 away from the arc tube 7 is upward and provided with a nozzle 9. The purpose of this arrangement is that the river water passes through the intermediate tube 5, the rotating tube 6, the arc tube 7, and the conduit 8 from the vertical tube 4 in sequence into the nozzle 9, and then sprays upward from the nozzle 9. Because the intermediate tube 5 is inclined, the nozzle 9 can spray water above the flower and grass planting area 2, so as to imitate rain to water the flowers and plants in the flower and grass planting area 2, which is simple and convenient to use.

[0026] like Figure 1 and Figure 2 and Figure 3 The rotating tube 6 is rotatably connected to the middle tube 5. When the pumping part works and the water flows through the middle tube 5 and the rotating tube 6, a rotating part for driving the rotating tube 6 to rotate is provided on the rotating tube 6. The purpose of this arrangement is that when the water passes through the middle tube 5, the rotating tube 6, the arc tube 7, the conduit 8 and then is sprayed out from the nozzle 9, the water flow passing through the middle tube 5 and the rotating tube 6 will drive the rotating tube 6 to rotate through the rotating part. At this time, the arc tube 7, the conduit 8 and the nozzle 9 will rotate with the rotating tube 6. At this time, the spraying range of the nozzle 9 can be increased, and it is simple and convenient to use.

[0027] like Figure 3 and Figure 4 and Figure 5 The rotating member includes a horizontal plate 10 arranged between the opposite sides of the rotating tube 6, and the side of the horizontal plate 10 close to the intermediate tube 5 is fixedly connected to a central axis 12 located in the intermediate tube 5. The central axis 12 is coaxial with the rotating tube 6. A plurality of blades 13 are obliquely arranged on the central axis 12, and each blade 13 is evenly distributed along the axis of the central axis 12. The purpose of this arrangement is that the water flow passing through the intermediate tube 5 and the rotating tube 6 can drive the central axis 12 to rotate through each inclined blade 13. At this time, the central axis 12 will drive the rotating tube 6 to rotate on the intermediate tube 5 through the horizontal plate 10, which is simple and convenient to use.

[0028] like Figure 3 and Figure 4 and Figure 6The top of the mounting plate 3 is provided with two opposite vertical plates 14, the middle tube 5 and the vertical plate are both located between the two vertical plates 14, the middle tube 5 includes a hose 15 and a transition tube 16 connected to the hose 15, the end of the hose 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 hose 15, the central axis 12 is located in 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 conduit 8 is provided with a The power member is used to drive the transition pipe 16 to rotate along the axis of the rotating shaft 17. The power member includes a counterweight block 18 arranged on the side of the conduit 8 away from the arc tube 7. The conduit 8, the nozzle 9 and the counterweight block 18 are all located on the left side above the rotating shaft 17. The two vertical plates 14 are provided with limiting members for limiting the rotation angle of the rotating shaft 17. The limiting members include a ring 19 arranged on the side of the vertical plate 14 close to the rotating shaft 17. The rotating shaft 17 is coaxial with the ring 19.

As the rotating tube 6 rotates on the transition tube 16, the conduit 8, the nozzle 9 and the counterweight 18 rotate to the upper right side of the rotating shaft 17. The conduit 8, the nozzle 9 and the counterweight 18 will be affected by gravity and drive the transition tube 16 to rotate along the axis of the rotating shaft 17 through the arc tube 7 and the rotating tube 6. At this time, the transition tube 16 will drive the rotating shaft 17 to rotate on the vertical plate 14, and the spraying range of the nozzle 9 can be further improved. When the rotating shaft 17 rotates, the swing plate 20 will rotate with the rotating shaft 17. At this time, due to the position of the swing plate 20 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 conduit 8, the nozzle 9 and the counterweight 18 rotate to the upper left side of the rotating shaft 17 with the rotation of the rotating tube 6 on the transition tube 16, the conduit 8, the nozzle 9 and the counterweight 18 will be affected by gravity, and the transition tube 16 will be driven by the arc tube 7 and the rotating tube 6 to 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 be swung along the rotation axis of the rotating shaft 17 during the rotation of the rotating tube 6.

[0030] like Figure 2A threaded barrel 22 is coaxially provided on one end of the outer wall of the conduit 8 close to the nozzle 9, and a protective barrel 23 is coaxially threadedly connected on the outer wall of the threaded barrel 22. The nozzle 9 is located in the protective barrel 23.

When the nozzle 9 is working, the protective barrel 23 is first unscrewed from the threaded barrel 22.

[0031] like Figure 2 The pumping part includes a support plate 24 vertically arranged on the top of the mounting plate 3 and a water pump 25 arranged on the vertical pipe 4. The water pump 25 is fixedly installed with the support plate 24. The bottom end of the vertical pipe 4 is connected with a water pump 26 for extracting river water, and the water pump 26 is L-shaped. The purpose of this arrangement is to turn on the water pump 25. At this time, the river water can be pumped into the vertical pipe 4 through the cooperation of the water pump 25 and the water pump 26. A filter barrel 27 for filtering the river water is provided at one end of the water pump 26 located in the river water, which is simple and convenient to use.

[0032] Embodiment 2: A slope protection method according to the above-mentioned embodiment 1: when in use, the river water is pumped to the vertical pipe 4 through the pumping part, and then the river water enters the water spraying part from the vertical pipe 4, and is sprayed from the water spraying part toward the top of the flower and grass planting area 2.
