[0031] Embodiment 2

[0032] Refer to the attached Figure 5 and Figure 6On the basis of the first embodiment, in order to realize the assembly and fixation of the protection grid 3 and the base plate 1, an assembly groove 2 is opened on the top surface of the base plate 1, and the long side length of the assembly groove 2 is equal to the long side length of the base plate 1. The protection grid 3 is inserted into the assembly groove 2, and the long side length of the protection grid 3 is equal to the long side length of the assembly groove 2; an anti-deflection plate 4 is fixed on the surface of the protection grid 3, and two anti-deflection plates 4 are provided. The two anti-deflection plates 4 are symmetrically distributed about the protection grid 3, and the height of the anti-deflection plates 4 is equal to the height of the protection grid 3. The anti-deflection plate 4 is slidably connected in the limiting slide groove 5, and the limiting slide groove 5 is opened on two parallel side walls of the assembly groove 2; the bolt 6 penetrates the base plate 1, the assembly groove 2 and the anti-deflection plate 4 and is locked and fixed.

[0033] When inserting the protective grid 3 into the assembling groove 2, align the anti-deflection plate 4 with the limiting slide groove 5. As the protective grid 3 falls, the anti-deflection plate 4 is inserted into the limiting slide groove 5, so as to prevent the protective grid 3 from sliding sideways in the assembling groove 2. Then, the bolts 6 are passed through the reserved holes on the surface of the base plate 1, the protective grid 3 and the anti-deflection plate 4 and then locked. The protective grid 3 and the base plate 1 are detachable structures, which facilitates the separate replacement and use of the base plate 1 and the protective grid 3.

[0034] Embodiment 3

[0035] Refer to the attached Figures 6 to 9 as well as Fig.12 On the basis of the second embodiment, in order to realize the protection effect of the protective grid 3 when used alone, a bottom groove 8 is provided on the bottom surface of the protective grid 3, and the bottom groove 8 corresponds to the side groove 7 one by one. The cone head 10 is in the bottom groove 8, and an installation groove 11 is provided on the top surface of the protective grid 3. There are two installation grooves 11, and the two installation grooves 11 are respectively distributed at both ends of the top surface of the protective grid 3. A limiting shaft 12 is fixed between two parallel side walls of the installation groove 11, and the limiting shaft 12 passes through the pulley 13, and the diameter of the pulley 13 is greater than the height of the installation groove 11.

[0036] After loosening the bolts 6 and removing them from the protective grid 3, pull the protective grid 3 away from the base plate 1, then flip the protective grid 3 180 degrees, the pulley 13 contacts the ground, push the protective grid 3 to the use site, flip the protective grid 3 180 degrees to reset it, then screw the screw 9 downward to insert the cone head 10 into the soil layer, so that the protective grid 3 can be disassembled and used alone.

[0037] Embodiment 4

[0038] Refer to the attached Fig.10 and Fig.11 On the basis of Example 3, in order to connect and fix the two groups of protective fences, bolt holes are opened on the surface of the connecting plate 14, and the connecting plates 14 on both sides of the protective grid 3 are staggered, so that the two groups of protective fences can be assembled end to end and fixed by bolts.

[0039] When the protective grid 3 is actually in use, the anti-deflection plate 4 is aligned with the limiting slide groove 5. As the protective grid 3 falls, the anti-deflection plate 4 is inserted into the limiting slide groove 5, so as to prevent the protective grid 3 from sliding sideways in the assembly groove 2. Then the bolts 6 are passed through the base plate 1, the protective grid 3 and the reserved holes on the surface of the anti-deflection plate 4 and are locked. The protective grid 3 and the base plate 1 are detachable structures, which facilitates the separate replacement and use of the base plate 1 and the protective grid 3. After the loose bolts 6 are disassembled from the protective grid 3, the protective grid 3 is pulled out from above the base plate 1. Then, after the protective grid 3 is turned 180 degrees, the pulley 13 contacts the ground. After the protective grid 3 is pushed to the use site, the protective grid 3 is turned 180 degrees and reset, and then the screw 9 is screwed downward to insert the cone head 10 into the soil layer, so that the protective grid 3 can be disassembled and used separately.
