Detailed Embodiment

[0020] The following further elaborates on the present invention in detail in conjunction with the drawings and specific embodiments.

[0021] As Figures 1-3 shown, a fence device for mine protection and its usage method include a main fence 6 and a secondary fence 10. Support square boxes 2 are installed on both sides of the main fence 6. Opposite surfaces of the two support square boxes 2 are provided with first sliding grooves 12. A connecting rod 9 is slidably connected between the two first sliding grooves 12. A locking mechanism is provided on the connecting rod 9. The secondary fence 10 is installed at the top of the connecting rod 9. A bottom plate 1 is provided at the bottom of the main fence 6, and a plurality of anchor bolts 22 are provided on the bottom plate 1.

[0022] The locking mechanism includes a sliding seat 8, an adjusting screw 13 and a locking nut 14. A support sliding column 7 is provided inside the support square box 2. The sliding seat 8 is slidably connected to the support sliding column 7. The two sliding seats 8 are respectively connected to both ends of the connecting rod 9. An adjusting screw 13 is provided on the sliding seat 8. A second sliding groove 15 is provided on the side of the support square box 2. The adjusting screw 13 is slidably connected in the second sliding groove 15. The locking nut 14 is provided on the adjusting screw 13 and is located outside the second sliding groove 15.

[0023] On the back of the secondary fence 10, a fixed sleeve 25 is connected through a universal coupling 24. A plugging nail 28 is threadedly connected inside the fixed sleeve 25. A fastening nut 27 is provided on the plugging nail 28.

[0024] There are two sets of the universal coupling 24, the fixed sleeve 25, the fastening nut 27 and the plugging nail 28, which are convenient for stabilizing the enclosure device.

[0025] On both sides of the front of the secondary fence 10, reinforcing connecting rods 18 are provided. A positioning plate 17 is provided on the bottom surface of the reinforcing connecting rod 18. The positioning plate 17 is fixedly connected to the connecting rod 9. A secondary protective net 19 is provided between the two reinforcing connecting rods 18. The bottom of the secondary protective net 19 is installed on the positioning plate 17. While the reinforcing connecting rod 18 strengthens the structure of the secondary fence, it also ensures the stability of the secondary protective net 19, making the entire protection system more solid and capable of withstanding a certain degree of external force impact.

[0026] A main protective net 20 is provided between the two support square boxes 2. The main protective net 20 is located on the front side of the main fence 6.

[0027] One of the support square boxes 2 is provided with a connection slot 4, and the other support square box 2 is provided with a connection plug 3. The connection plug 3 on the adjacent support square box 2 is inserted into the connection slot 4, and multiple enclosures can be combined together.
