A sliding groove 18 is provided on the inner wall of the sleeve 17. The sliding groove 18 and the slider 19 are slidably connected.

[0036] Furthermore, a first magnet 22 is fixedly mounted below the limiting block 21 , and a second magnet 23 is fixedly mounted above the adjusting member 12 , and the first magnet 22 and the second magnet 23 attract each other.

[0037] Furthermore, a grounding column 24 is provided below the support member 1, and the grounding column 24 slides through the groove 14. A cavity 25 is provided inside the grounding column 24, and a push rod 27 is slidably inserted inside the cavity 25. The upper end of the push rod 27 is fixedly connected to the bottom of the support member 1, and a stable structure is provided inside the cavity 25.

[0038] Specifically, the stable structure includes a mounting block 26 and a limiting hole 29. The limiting hole 29 is provided on the outside of the grounding column 24.

The No. 2 spring 28 is fixedly connected to the inner wall of the grounding column 24. The outside of the grounding column 24 is fixedly provided with a protrusion 30.

[0039] Furthermore, there are at least two groups of horizontal protective nets 3, and a fixing plate 31 is arranged above two adjacent groups of support members 1. A slot 32 is opened inside the fixing plate 31, and the slot 32 is slidably connected to the grounding column 24. A protective structure is arranged between the two groups of fixing plates 31.

[0040] The protective structure includes support plates 33, and the number of support plates 33 is two groups. The two groups of support plates 33 are respectively fixedly installed on the adjacent sides of the two groups of fixed plates 31. Two groups of adjustment plates 34 are rotatably installed on the side of the support plates 33 away from the fixed plates 31. The ends of the two adjacent groups of adjustment plates 34 away from the support plates 33 are rotatably installed with shafts 35. Short plants 7 are planted between the four groups of adjustment plates 34.

[0041] A method for arranging a riverbank vegetation buffer strip, using the above riverbank vegetation buffer strip, includes the following:

[0042] S1, organic fertilizer 5 is laid on soil 4, gravel 10 is laid on top of the organic fertilizer 5, tall plants 6 and short plants 7 are planted in sequence on top of the gravel 10, and grass 8 is planted around the tall plants 6 and the short plants 7;

[0043] S2, fix the protection net 3 to the river bank through the grounding column 24, adjust the bending curvature of the spring piece 2 through the adjusting member 12, set the sandbag 9 on one side of the protection net 3, and the two groups of protection nets 3 are designed in a trapezoidal shape;

[0044] S3. Connect two adjacent groups of protection nets 3 by setting a fixing plate 31.

[0045] When in use, the soil 4 is laid on the river bank, and the organic fertilizer 5 is laid on the top of the soil 4. The upper and lower groups of protective nets 3 are connected by the adjusting member 12. At this time, the two groups of protective nets 3 are designed in a stepped shape. The upper protective net 3 sets the adjusting member 12 on the outside of the grounding column 24, and the lower protective net 3 sets the adjusting member 12 on the outside of the connecting column 16 and the sleeve 17. During this process, the sleeve 17 passes through the through hole 13, and the limit block 21 slides inside the limit groove 15. When the limit block 21 is removed from the limit groove 15, the adjusting member 12 is rotated under the action of the connecting member 11. At this time, the limit block 21 is rotated to not overlap with the limit groove 15, so that the sleeve 17 will not be separated from the adjusting member 12. Under the mutual cooperation of the No. 1 magnet 22 and the No. 2 magnet 23, the sleeve 17 will not protrude above the adjusting member 12. It is suitable for adjusting members 12 of different thicknesses and can increase the stability between the support member 1 and the adjusting member 12.

[0046] The distance between the supporting members 1 on both sides of the protective net 3 can be adjusted by the adjusting member 12. Under the action of the spring piece 2, the curvature of the protective net 3 can be adjusted. A sandbag 9 is provided on one side of the protective net 3, which can effectively reduce water and soil erosion on the river bank and reduce the impact of wind and sand on the river bank, so that objects on the river bank are not easy to slide into the river water.

[0047] Insert the grounding column 24 into the soil 4. When the protrusion 30 contacts the surface of the organic fertilizer 5, the grounding column 24 stops moving, and the support 1 continues to drive the push rod 27 to move into the cavity 25. When the push rod 27 contacts the mounting block 26, the push rod 27 pushes the mounting block 26 to move from the inside of the limiting hole 29 to the outside of the grounding column 24. At this time, the No. 2 spring 28 is compressed, and the mounting block 26 is inserted into the soil 4, increasing the contact area between the device and the soil 4, thereby increasing the stability of the device.

[0048] Furthermore, when there are at least two groups of protection nets 3 in the same row, the two groups of slots 32 provided on the fixing plate 31 are respectively sleeved on the outside of the sleeves 17 installed on the two adjacent groups of support members 1, so that the two groups of protection nets 3 can be fixed together. With the cooperation of the support plate 33, the adjustment plate 34 and the shaft member 35, when the curvature of one group of protection nets 3 is adjusted, all protection nets 3 can be adjusted at the same time, which is beneficial to improving the efficiency of the buffer zone arrangement. When the water flow hits between the two groups of protection nets 3, it can flow along the surface of the protection net 3 to the center of the protection net 3, reducing the impact force of the water flow on the soil, which is beneficial to reducing soil erosion on the river bank.

[0049] The tall plants 6 are planted inside the through holes 13 opened on the connecting piece 11, and the short plants 7 are planted between the four groups of adjustment plates 34, which can effectively reduce the impact of wind on the tall plants 6 and the short plants 7, so that in strong winds, the tall plants 6 and the short plants 7 will not be blown down. The grass 8 is planted around the tall plants 6 and the short plants 7 to further improve the stability of the buffer zone. The gravel 10 is laid in the gaps of the grass 8, and the gravel 10 is located above the organic fertilizer 5, so as to further reduce the impact of wind and sand on the soil 4.

[0050] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention.
