[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-3 The utility model provides a rockfall protection device for mine restoration and management, including a vertical pole 1, the number of the vertical poles 1 is two, the upper and lower ends of the two vertical poles 1 are respectively provided with connecting seats 2, cables 3 are respectively provided between the two connecting seats 2 at the upper end and between the two connecting seats 2 at the lower end, the number of the cables 3 is two, the outer ends of the two cables 3 are respectively provided with connecting hooks 4, the connecting hooks 4 are hooked with the connecting seats 2, tension hydraulic rods 5 are respectively provided on the left and right sides of the two cables 3, and limit seats 6 are respectively provided at both ends of the tension hydraulic rod 5, the cable 3 passes through the limit seat 6 and is fixedly connected with the limit seat 6, and a protective net 7 is provided between the two cables 3.

[0016] When in use, the two vertical poles 1 are set to the positions where rockfall protection is required, connecting seats 2 are set on the two vertical poles 1, and the cables 3 are hung on the connecting seats 2 through the connecting hooks 4, so that the two cables 3 are correspondingly set to the upper and lower ends between the two vertical poles 1, and limit seats 6 are respectively set on the left and right sides of the two cables 3, and a tension hydraulic rod 5 is set between the two limit seats 6 on the left and right sides. Through the pulling force of the tension hydraulic rod 5, the two ends of the cable 3 are respectively contracted and bent, and a protection net 7 is set between the upper and lower cables 3. The rockfall falls on the protection net 7, and the protection net 7 prevents the rockfall from continuing to roll. When larger rockfall falls, the protection net 7 blocks the rockfall. Since the rockfall is larger and has the potential energy to continue rolling, the tension hydraulic rod 5 is pulled by the cable 3 to expand, and the rolling potential energy of the larger rockfall is absorbed by the tension hydraulic rod 5.

[0017] The connecting seat 2 is sleeved on the upper and lower ends of the vertical pole 1, and the connecting seat 2 is fixedly connected to the vertical pole 1 by welding. The inner end of the connecting seat 2 is provided with a hooking hole 8, and the connecting hook 4 is hooked with the hooking hole 8. By setting the hooking hole 8 on the connecting seat 2 and hooking the connecting hook 4 with the hooking hole 8, the cable 3 is hooked to the connecting seat 2.

[0018] A rotating connecting seat 9 is provided at the position corresponding to the inner end of the limit seat 6 and the tension hydraulic rod 5. The two ends of the tension hydraulic rod 5 are rotatably connected to the rotating connecting seat 9 through a rotating shaft. By providing the rotating connecting seat 9 on the limit seat 6, the tension hydraulic rod 5 is rotatably connected between the limit seats 6.

[0019] The cable 3 passes through the two limit seats 6 and is provided with a bending section 10 at a position corresponding to the tension hydraulic rod 5. The tension hydraulic rod 5 makes the cable 3 present the bending section 10, and the potential energy of the continued rolling of the falling rocks is absorbed by the deformation of the bending section 10 and the tension hydraulic rod 5.

[0020] A fixing seat 11 is provided at the lower end of the two vertical poles 1, and the vertical poles 1 are fixed to a suitable position through the fixing seat 11.
