[0028] The soil and water conservation protection net is installed on the lower inclined surface slope section 3 through a fixing device. The soil and water conservation protection net includes a plurality of detachably connected protection nets 4. A plurality of first connecting snap-fit ​​limiting components are arranged around the protection nets 4. A plurality of second connecting snap-fit ​​limiting components are arranged around adjacent protection nets 4. The plurality of protection nets 4 are detachably connected by locking the first connecting snap-fit ​​limiting components with the second connecting snap-fit ​​limiting components.

[0029] Embodiment 1:

[0030] When the present invention is in use, a plurality of protective nets 4 are detachably connected by locking the first connecting clamping limiting component with the second connecting clamping limiting component.

[0031] When one of the protective nets 4 is damaged, the damaged part of the protective net can be directly removed and replaced. The above structure facilitates the partial replacement of the protective net without removing the undamaged protection from the slope, which can reduce the repair time of the protective net and reduce the cost of using the protective net.

[0032] The first connection engaging limiting component is a circular ring structure 5, and the second connection engaging limiting component includes a circular ring shell 7, an adjusting button 8 and an adjusting spring 9. The adjusting spring 8 is installed in the circular ring shell 7, and the adjusting button 8 is inserted into the adjusting spring 9 at one end extending into the circular ring shell 7. The interior of the circular ring shell 7 is provided with a guide channel 10 for the adjusting button 8 to slide. An adjusting hole 11 is opened at the top end of the circular ring shell 7, and a protrusion 12 is provided at the top end of the adjusting button 8. The protrusion 12 extends from the adjusting hole 11 at the top end of the circular ring shell 7 to facilitate manual adjustment of the adjusting button 8.

[0033] An opening 13 is provided on one side of the annular shell 7 , and the first connection engaging limiting component is sleeved on the annular shell 7 through the opening 13 . A limiting protrusion 14 is provided inside the annular shell 7 for limiting the adjusting spring 9 .

[0034] When this embodiment is in use, when one of the protective nets is damaged, the adjustment button 8 can be directly slid by hand. The adjustment button 8 slides along the guide channel 10 in the annular shell 7 and squeezes the adjustment spring 8 inside it. The first connecting snap-fit ​​limiting component (that is, the ring) on ​​the adjacent protective net can be taken out from the second connecting snap-fit ​​limiting component in the annular shell 7 to achieve the removal of the protective net. The operation is simple.

[0035] Take out the new protective net, slide the adjustment button 8 by hand, the adjustment button 8 slides along the guide channel 10 in the annular shell 7 and squeezes the adjustment spring 8 inside it, and the first connection clamping limit component (i.e., the annular ring) on ​​the new protective net is sleeved in the annular shell 7 on the adjacent protective net, release the adjustment button 8 by hand, the adjustment spring 8 returns to its original state and pushes the adjustment button 8 to close the annular shell 7. Through the above operation, the installation and removal of the protective net can be realized by sliding the adjustment button with one key, which is simple to operate and greatly reduces the repair time of the protective net.

[0036] The fixing device includes a plurality of fixing nails 21, and a plurality of fixing holes 22 cooperating with the fixing nails 21 are arranged on the slope body 1. The fixing nails 21 pass through the annular shell 7 and are inserted into the fixing holes 22 on the slope body 1 for installing and fixing the protective net.

[0037] When the present invention is used, the fixing nail 21 can be directly used to pass through the annular shell 7 at the edge of the protective net and inserted into the fixing hole 22 on the slope body 1. The installation and fixing of the protective net can be achieved through the above operation.

[0038] Embodiment 2:

[0039] When the present invention is in use, a plurality of protective nets 4 are detachably connected by locking the first connecting clamping limiting component with the second connecting clamping limiting component.

[0040] When one of the protective nets 4 is damaged, the damaged part of the protective net can be directly removed and replaced. The above structure facilitates the partial replacement of the protective net without removing the undamaged protection from the slope, which can reduce the repair time of the protective net and reduce the cost of using the protective net.

[0041] The first connection engagement limiting component is an engagement base 14 on which an engagement slot 15 is provided. The second connection engagement limiting component includes a fixed base 23 on which a rotatably connected snap ring 24 is provided for engagement and locking with the engagement slot 15 .

[0042] The fixed base 23 is rotatably connected to two groups of adjustment plates 16 , a fixed shaft 17 is installed between the two groups of adjustment plates 16 , a connecting rod 18 is connected to the fixed shaft 17 , the retaining ring 24 is rotatably connected to the end of the rotating shaft 16 , and a control handle 18 is provided at the end of the adjustment plate 17 .

[0043] The connecting rod 18 is a threaded connecting rod, and a connecting hole 19 matching the threaded connecting rod is provided on the fixed shaft 17. The inner wall of the connecting hole 19 is smoothly provided, and a limit nut 20 is installed at the connecting protruding end of the connecting rod 18 and the fixed shaft 17.

[0044] When the present embodiment is in use, when one of the protective nets is damaged, the control handle 18 can be turned upwards by hand. The upward movement of the control handle 18 drives the corresponding front end of the connecting rod 18 to move downward. Since the snap ring 24 is rotatably connected to the end of the rotating shaft 16, the snap ring 24 is driven to disengage from the engaging groove 15 on the engaging base 14. The damaged protective net can be disassembled through the above operation. The installation and disassembly of the protective net can be achieved by adjusting the control handle through the above operation. The operation is simple and greatly reduces the repair time of the protective net.

[0045] When using this embodiment, the staff can adjust the spacing between the protective nets as needed. During the adjustment process, the limiting nut 20 on the connecting rod 18 can be directly loosened. After loosening, the connecting rod 18 can be pulled to adjust the relative position between the connecting rod 18 and the fixed shaft 17. When the adjustment is completed, the limiting nut 20 can be directly tightened. Through the above operation, the staff can adjust the spacing between the protective nets as needed, thereby meeting the use requirements of the on-site slope protection.

[0046] Embodiment three:

[0047] The protective net is arranged in a rectangular grid structure.

[0048] The upper arc slope section 2 in the slope body 1 is an inwardly concave arc surface, and a plurality of water outlet channels 25 are arranged at the top of the upper arc slope section 2. A plurality of water inlet channels 6 are arranged at the bottom end of the slope body 1. The water inlet channels 6 are arranged in the gaps between the protective nets 4. The water outlet channels 25 are connected to the water inlet channels 6. The water outlet channels 25 and the water inlet channels 6 are integrally formed, and the diameter of the water inlet channel 6 is smaller than the diameter of the water outlet channels 25.

[0049] The water outlet channels 25 are provided in two groups, and the two groups of water outlet channels 25 are distributed in a straight line. The water inlet channels 6 are provided in four groups, and the four groups of water inlet channels 6 are arranged in a straight line, and the intervals between two adjacent groups of water inlet channels are equal.

[0050] Among them, the four groups of water inlet channels 6 are connected to the connecting ends of the two groups of water inlet channels 25, and the water inlet channels 6 and the water outlet channels 25 are integrally formed and arranged inside the slope body.

[0051] When the present embodiment is in use, the rectangular grid-shaped protective net can be directly fixed on the protective slope by fixing nails, or it can be installed on the dam. When the river water flow in the dam impacts the protective net on the slope protection body, the protective net can effectively prevent water and soil loss. When the water flow begins to impact the slope protection structure, the water flow passes through a plurality of fine water inlet channels 6, and the water inlet channels 6 are provided with 4 groups. The water flow can be divided into 4 groups of fine diversions through the water inlet channels 6, thereby reducing the impact of the water flow on the slope protection surface. The water flow entering the water inlet channel 6 flows out through 2 groups of water outlet channels 25. Since the upper arc slope section 2 in the slope body 1 is an inwardly concave arc surface, the water flow flowing out of the water outlet channel 25 passes through the upper arc slope section 2 and flows downward along the arc surface. The above structure can divide the water flow into multiple streams and then come out of the dam, thereby alleviating the impact force on the dam, improving the water flow impact resistance of the water-facing surface of the dam body, and extending the service life of the dam.

[0052] As a further elaboration of the present invention, the protective net is arranged in a honeycomb structure.

[0053] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
