Description

Technical Field

[0001] This utility model belongs to the field of protective netting technology, and specifically relates to a protective netting. Background Technology

[0002] In the process of mine ecological restoration, three-dimensional protective nets are used to cover the slopes of the mine, and nutrient substrates and seeds are sprayed on the nets. However, in actual operation, due to mining, there are large pits and end faces on the slopes. After the protective nets are installed, some of these pits and end faces are difficult to cover with the nets, and some parts of the three-dimensional protective nets are suspended at large distances. The dense three-dimensional protective nets can also obstruct the nutrient substrates, making it difficult for them to seep down to the back of the nets. After the nutrient substrates and seeds are sprayed, the growth environment for the seeds is poor, making it difficult for them to survive, thus affecting the effectiveness of mine ecological restoration.

Detailed Implementation

[0018] Please see Figures 1-4 The present invention provides the following technical solution: a protective net, comprising a protective net body 1 and a spraying notch 11, a support frame plate 2 detachably connected to the protective net body 1, a cutting plate connecting plate 21 hinged to the support frame plate 2, a plurality of mesh locking posts 22 fixedly connected to the top of the support frame plate 2 and the cutting plate connecting plate 21, an upper pressing frame plate 3 detachably connected to the top of the support frame plate 2, a plurality of clearance holes 31 opened on the upper pressing frame plate 3, and a plurality of mesh locking posts 22 respectively inserted into the plurality of clearance holes 31.

[0019] In this implementation plan: Workers lay the protective net body 1 on the slope and then secure it using bolts or other fixing tools. After the protective net body 1 is fixed, if there are recessed ends on the back that are difficult to cover using the deformation of the protective net body 1 itself, workers manually cut spraying notches 11 at the corresponding locations on the protective net body 1. During cutting, a support frame plate 2 is placed over the top of the protective net body 1, and the spraying notches 11 are cut according to the inner edge contour of the support frame plate 2. Then, the spraying... The spray pipe is inserted into the recessed end face on the rear side of the protective net body 1 to spray and inject filler material. Then, the support frame plate 2 is bent and inserted into the back of the protective net body 1. The protective net body 1 at the edge of the spray notch 11 is engaged with the mesh engagement post 22 located at the top of the support frame plate 2. Then, the cut-off mesh is covered on the corresponding position of the cut-off piece connecting plate 21, and the mesh is engaged with the mesh engagement post 22 on the cut-off piece connecting plate 21. Then, the upper pressing frame plate 3 is aligned and covered on the top of the support frame plate 2, and the positioning post 4 is inserted. Through the positioning hole 32, workers use the clamping nut 41 to fix the upper clamping frame plate 3. The support frame plate 2 and the upper clamping frame plate 3 clamp and fix the protective net body 1 and the cut-off mesh. The spray notch 11 allows workers to easily spray filling onto the suspended part behind the protective net body 1. The support frame plate 2, the cut-off piece connecting plate 21, and the mesh clamping post 22 can easily and securely position the edge of the cut notch of the protective net body 1 and the cut-off mesh, further connecting it with the upper... The pressing frame plate 3 and the clearance hole 31 press and fix the support frame plate 2, the cutting piece connecting plate 21, the mesh clamping post 22, the protective net body 1, and the cut-off mesh piece. This can quickly seal the cut-off gaps in the protective net body 1, making it easier for workers to spray and cover the surface of the protective net body 1. The dense distribution of the mesh clamping posts 22 can increase the number of connection points with the protective net body 1, share the force, and prevent the protective net body 1 from breaking at the stress points, thus preventing cuts from appearing in the protective net body 1.

[0020] A connecting shaft 211 is fixedly connected to one side of the cutting plate connecting plate 21. The connecting shaft 211 is fixedly connected to the top of the support frame plate 2. The cutting plate connecting plate 21 is hinged to the support frame plate 2 through the connecting shaft 211. By setting the connecting shaft 211, the connection between the cutting plate connecting plate 21 and the support frame plate 2 can be facilitated. When cutting the protective net body 1, the cutting plate connecting plate 21 can be flipped and lifted to directly expose the inner edge of the support frame plate 2.

[0021] A bottom limiting strip 23 is fixedly connected to the inner wall of the support frame plate 2. The bottom limiting strip 23 is attached to the bottom end of the cutting strip connecting plate 21. By setting the bottom limiting strip 23, the cutting strip connecting plate 21 can be supported to limit the flipping angle of the cutting strip connecting plate 21 and improve the clamping effect on the netting cut off from the protective net body 1.

[0022] Two flexible connecting pieces 24 are fixedly connected to the support frame plate 2, and the two flexible connecting pieces 24 are positioned correspondingly. By setting the flexible connecting pieces 24, the support frame plate 2 can be bent, so that it can be inserted into the back side of the protective net body 1 through a smaller gap.

[0023] The upper pressing frame plate 3 has positioning holes 32 at all four corners. By setting the positioning holes 32, the insertion positioning post 4 can be moved aside, and the upper pressing frame plate 3 can be positioned in cooperation with the insertion positioning post 4, so that the positioning hole 31 on the upper pressing frame plate 3 can be used to match the position of the mesh clamping post 22, so that the mesh clamping post 22 can be accurately inserted into the positioning hole 31.

[0024] Each of the four corners of the support frame plate 2 is fixedly connected with a plug-in positioning post 4, and the four plug-in positioning posts 4 are respectively inserted into the four positioning holes 32; by setting the plug-in positioning posts 4, the upper pressing frame plate 3 can be positioned, and the size of the plug-in positioning post 4 matches the size of the positioning hole 32.

[0025] The outer wall of the insertion positioning post 4 is threaded with a press-fit fastening nut 41, which is pressed onto the top of the upper press-fit frame plate 3; the press-fit fastening nut 41 can press onto the top of the upper press-fit frame plate 3 to fix the upper press-fit frame plate 3.

[0026] The working principle and usage process of this utility model are as follows: Workers lay the protective net body 1 on the slope and then fix it using bolts or other fixing tools. After the protective net body 1 is fixed, if there is a recessed end face on the back that is inconvenient to cover with the deformation of the protective net body 1 itself, workers manually cut a spraying notch 11 at the corresponding location on the protective net body 1. During cutting, the support frame plate 2 is placed over the top of the protective net body 1, and the spraying notch 11 is cut according to the inner edge contour of the support frame plate 2. Then, the spraying pipe is inserted into the recessed end face on the back of the protective net body 1 to spray and inject filler material. Finally, the support frame plate 2 is placed over the recessed end face on the back of the protective net body 1. After the support frame plate 2 is bent, it extends into the back of the protective net body 1. The protective net body 1 at the edge of the spray notch 11 is engaged with the mesh engagement post 22 located at the top of the support frame plate 2. Then, the cut-off net is covered on the corresponding position of the cut-off piece connecting plate 21, and the net is engaged with the mesh engagement post 22 on the cut-off piece connecting plate 21. Then, the upper pressing frame plate 3 is aligned and covered on the top of the support frame plate 2. The insertion positioning post 4 passes through the positioning hole 32. The worker uses the pressing fastening nut 41 to fix the upper pressing frame plate 3. The support frame plate 2 and the upper pressing frame plate 3 clamp and fix the protective net body 1 and the cut-off net.
