[0061] A first frame 201 is provided on the slope 1. A protective net 205 is provided in the middle of the first frame 201. Connecting protrusions 2051 are fixedly connected to the four sides of the protective net 205. A positioning bend 206 is provided on the top of the connecting protrusion 2051. The positioning bend 206 is fixedly installed on the first frame 201 by fixing bolts 2061. The upper and lower ends of the first frame 201 are fixedly connected with hinge joints 2013. A second frame 202 is provided on one side of the first frame 201. A docking structure 2 is provided between the first frame 201 and the second frame 202. The docking structure 2 includes:

[0062] Corner inserts 2011 are fixedly connected to one side of the first frame 201 , and there are two sets of corner inserts 2011 , with locking slots 2012 formed on opposite sides of the corner inserts 2011 ;

[0063] Docking slots 2021 are provided on both sides of the second frame 202 , and the corner inserts 2011 are assembled into the docking slots 2021 ;

[0064] The fixed support frame 203 is fixedly connected to the middle of the top of the second frame 202. A movable groove 2031 is defined within the fixed support frame 203.

[0071] By rotating the turning handle 3032, the lead screw 3031 is driven to rotate. The lead screw 3031 is rotationally engaged with the first screw hole 3046 on the fixed convex column 3045. However, the fixed convex column 3045 is limited and guided on the guide rod 303 through the sliding support block 304. Furthermore, the lead screw 3031 drives the fixed convex column 3045 to move. The fixed convex column 3045 drives the sliding support block 304 to move. The sliding support block 304 drives the second hinge frame 3042 to move. The second hinge frame 3042 adjusts the angle of the first frame 201 through the support hinge rod 306. Furthermore, it can be flexibly adjusted according to the slope angle.

The reinforcement structure 4 includes a limit plate 401, a connecting strip plate 4011, a docking hole 4012, a pressing bolt 402, and an adjustment groove 4021. A limit plate 401 is provided on the top of the assembly top plate 307. Connecting strip plates 4011 are fixedly connected to both sides of the limit plate 401. The connecting strip plates 4011 are clamped in the top stud 3011 through the docking holes 4012. A pressing bolt 402 is provided in the middle of the limit plate 401. An adjustment groove 4021 is opened inside the pressing bolt 402. A screw 4022 is rotatably installed inside the adjustment groove 4021.

[0073] A bottom ring 403 is provided at the bottom of the screw 4022. A fixed convex frame 4031 is fixedly connected to the outside of the bottom ring 403. The fixed convex frame 4031 is hinged to one end of the bottom of the barbed plate 404 through the fifth pin 4032. A fifth hinge frame 4041 is fixedly connected to the inside of the barbed plate 404. The fifth hinge frame 4041 is hinged to one end of the bottom of the connecting rod 406 through the sixth pin 4042.

[0074] A moving belt ring 405 is provided on the outside of the screw 4022. A second screw hole 4051 is opened at the midpoint of the moving belt ring 405. Three notches 4052 are opened on the outside of the moving belt ring 405. A seventh pin 4053 is provided at the notch 4052. The seventh pin 4053 is hinged to one end of the top of the connecting rod 406.

[0075] By rotating the clamping bolt 402, the limit plate 401 is fixed on the top of the assembly top plate 307, and the clamping bolt 402 is inserted into the rock and soil. At this time, the movable belt ring 405 is driven downward by rotating the screw 4022. The movable belt ring 405 opens the barbed plate 404 through the action of the connecting rod 406, thereby further enhancing the grip of the reinforced structure.

[0076] Specific usage and function of this embodiment: In the present invention, first, concrete blocks 301 are poured on both ends of the slope 1, and studs 3011 are inserted into the concrete blocks 301. Then, the connecting frame 302 is installed on the studs 3011 and tightened by nuts 3024. At this time, the screw rod 3031 is driven to rotate by rotating the handle 3032. The screw rod 3031 is rotated and engaged with the first screw hole 3046 on the fixed boss 3045. However, the fixed boss 3045 is guided by the upper limit of the guide rod 303 through the sliding support block 304, and then the screw rod 3031 drives the fixed boss 3045 to move, and the fixed boss 304 5 drives the sliding support block 304 to move, and the sliding support block 304 drives the second hinge 3042 to move. The second hinge 3042 adjusts the angle of the first frame 201 through the support hinge rod 306, and can then be flexibly adjusted according to the slope angle to ensure that the protection net 205 fits the slope tightly, avoiding blind spots in protection, and effectively improving the comprehensiveness and reliability of slope protection. Then, the limiting plate 401 is placed on the top of the assembly top plate 307, and the clamping bolt 402 is rotated to tighten it. Then, the screw 4022 is rotated to drive the movable belt ring 405 to move downward, and the movable belt ring 405 is moved downward by the action of the connecting rod 406. The barbed plate 404 is stretched out to further enhance the grip of the reinforcement structure, enhance the overall stability of the slope protection device, and reduce the risk of displacement and loosening of the device due to external forces. Finally, the movable belt plate 204 is moved by pulling the toggle plate 2043, and the movable belt plate 204 drives the locking plug 2042 to retract. At this time, the docking slot 2021 on the second frame 202 is clamped onto the corner plug 2011. At this time, the toggle plate 2043 is released, because the movable belt plate 204 squeezes the spring 2034 on the connecting slide rod 2033 when moving, causing the spring 2034 to produce elastic deformation. When the pressure is lost, the spring 2034 releases the elastic force to push the moving belt plate 204 to move, and the moving belt plate 204 drives the locking insert 2042 to return and be inserted into the locking slot 2012, thereby completing the splicing of the first frame 201 and the second frame 202, reducing the preparation work of the middle section concrete and embedded parts. Only the embedded parts at both ends need to be prepared, and then the middle protective net 205 is quickly spliced with the two ends, which greatly shortens the construction time and speeds up the construction progress. It can protect the slope in time, effectively reducing the safety risks such as landslide and collapse caused by the lack of protection during construction, and ensuring the safety of the surrounding environment and personnel.
