[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figure 1-4 The present invention provides the following technical solution: an active protection net for slope reinforcement, including a grid assembly 1, an outer ring assembly 6 fixedly installed on the outer side of the grid assembly 1, two collars 5 on both sides of the outer ring assembly 6, an anchor rod 4 on the inner side of the collar 5, the outer ring assembly 6 and the multiple collars 5 are connected by two lifting extension devices 2, and an isolation protection device 3 is provided on the outer side of the collars 5.

[0023] Specifically, the lifting extension device 2 includes a connecting box 21, a first lead screw 22, a lifting plate 23, and an extension assembly 24. Multiple connecting boxes 21 are arranged between the outer ring assembly 6 and multiple collars 5. The first lead screw 22 is installed on the inner side of the connecting box 21 through a bearing. The lifting plate 23 is fixedly installed on one side of the collar 5, located outside the first lead screw 22 and inside the connecting box 21. The outer ring assembly 6 and the multiple connecting boxes 21 are connected through the extension assembly 24.

[0024] By adopting the above technical solution, the staff can adjust the height of each collar 5 when needed by cooperating with the first lead screw 22 and the lifting plate 23, thereby better adapting to different slope conditions.

[0025] Specifically, the inner side of the connecting box 21 and one side of the lifting plate 23 are fitted together.

[0026] By adopting the above technical solution, the protective net can limit the movement of the lifting plate 23 through the connecting box 21, thereby preventing the lifting plate 23 from rotating or deviating during movement and ensuring the normal operation of the work.

[0027] Specifically, the extension component 24 includes screws 241, threaded holes 242, fixing sleeves 243, moving posts 244, and extension mesh 245. Two fixing sleeves 243 are fixedly installed on both the upper and lower sides of the outer ring component 6. A moving post 244 is fixedly installed on one side of the connecting box 21 and inside the fixing sleeve 243. An extension mesh 245 is fixedly installed on one side of the two connecting boxes 21 and between the two fixing sleeves 243 and on one side of the grid component 1. Screws 241 are threadedly installed on the edge of the fixing sleeve 243 away from the extension mesh 245. Multiple threaded holes 242 are opened on the edge of the moving post 244 away from the extension mesh 245.

[0028] By adopting the above technical solution, staff can adjust the protective area of ​​the protective net by using the combination of structures such as the extension net 245 and the movable post 244 when needed, thereby better meeting the work needs in different situations.

[0029] In this embodiment, when it is necessary to reinforce the slope with an active protective net, the workers rotate the first screws 22 in the two lifting extension devices 2 respectively. The first screws 22 are threadedly connected to the lifting plates 23, and the inner side of the connecting box 21 is in contact with one side of the lifting plate 23. Therefore, each first screw 22 drives each lifting plate 23 to rise and fall, thereby adjusting the height of each collar 5. Then, the workers tighten the screws 241 on each fixing sleeve 243 in the two extension components 24 respectively, so that they are disengaged from the threaded holes 242 on each moving column 244. Then, the two extension nets 245 and their connecting boxes 21 and moving columns 244 are pulled to move, thereby expanding the area of ​​the protective net. Then, the screws 241 are rotated in the opposite direction to connect with the corresponding threaded holes 242. Then, the workers cover the slope with the protective net, insert each anchor rod 4 through each collar 5 into the slope, and then reinforce the slope through the two extension nets 245 and the grid assembly 1 in the outer ring assembly 6.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the isolation protection device 3 includes a second lead screw 31, a movable plate 32 and an isolation cover 33. The second lead screw 31 is installed on one side of the connecting box 21 and on the side of the collar 5 via a bearing. The movable plate 32 is installed on the outside of the second lead screw 31 via a thread. The isolation cover 33 is fixedly installed on one side of the movable plate 32 and on the side of the collar 5 away from the connecting box 21.

[0032] By adopting the above technical solution, workers can protect the part of the anchor rod 4 on the ground by using the cooperation of the second screw rod 31 and the isolation cover 33 when needed, thereby reducing the possibility of the part of the anchor rod 4 on the ground being hit by external collisions, and thus preventing the protective net from loosening on the slope.

[0033] Specifically, the isolation protection device 3 also includes a guide rod 34, which is fixedly installed on one side of the connecting box 21 at a position between the second lead screw 31 and the collar 5.

[0034] By adopting the above technical solution, the protective net can limit the movement of the movable plate 32 by the guide rod 34, thereby preventing the movable plate 32 from rotating or deviating during movement and ensuring the normal operation of the work.

[0035] In this embodiment, when it is necessary to protect the portion of each anchor rod 4 on the slope surface, the operator can rotate the second screw 31 in each isolation protection device 3. The second screw 31 is threadedly connected to the moving plate 32, and the moving plate 32 is slidably connected to the guide rod 34. Therefore, each second screw 31 drives each moving plate 32 and its isolation cover 33 to move until each isolation cover 33 covers the portion of each anchor rod 4 on the slope surface, thereby protecting it and reducing the possibility of the portion of the anchor rod 4 on the ground being hit by external collisions, thus preventing the protective net from loosening on the slope.

[0036] The structure and principle of the grid assembly 1 (composed of protective grid and diamond mesh), anchor rod 4, collar 5, and outer ring assembly 6 (composed of transverse support rope, longitudinal support rope and stitching rope) of this utility model have been disclosed in the basalt fiber active slope protection net disclosed in Chinese patent application No. 201821755131.0. Its working principle is that the protective net formed by connecting transverse support rope, longitudinal support rope, diamond mesh and protective grid has high overall strength and can effectively restrain and limit the collapse, rolling and other damage of slope rock and soil. Moreover, all components are made of basalt fiber material, which has strong corrosion resistance and high temperature resistance, and is green and environmentally friendly. Under long-term external environmental action, the tensile strength is not easily reduced, thereby greatly increasing the service life of the protective net and improving the reliability and durability of the active protection net.

[0037] The working principle and usage process of this utility model are as follows: When it is necessary to use an active protective net to reinforce a slope, the operator rotates the first screw 22 in each of the two lifting extension devices 2. The first screw 22 is threadedly connected to the lifting plate 23, and the inner side of the connecting box 21 is in contact with one side of the lifting plate 23. Therefore, each first screw 22 drives each lifting plate 23 to rise and fall, thereby adjusting the height of each collar 5. Then, the operator screws the screws 241 on each fixing sleeve 243 in the two extension components 24, so that they are disengaged from the threaded holes 242 on each moving column 244. Then, the two extension nets 245 and their connecting boxes 21 and moving columns 244 are pulled to move, thereby expanding the area of ​​the protective net. Then, the screws 241 are rotated in the opposite direction to make them engage with the corresponding threaded holes 242. 42 is connected, and then the staff covers the slope with the protective netting, inserts each anchor rod 4 through each collar 5 into the slope, and then reinforces it with the grid assembly 1 in the two extension nets 245 and the outer ring assembly 6; when it is necessary to protect the part of each anchor rod 4 on the slope ground, the staff can rotate the second screw 31 in each isolation protection device 3. The second screw 31 is threadedly connected to the moving plate 32, and the moving plate 32 is slidably connected to the guide rod 34. Therefore, each second screw 31 drives each moving plate 32 and its isolation cover 33 to move until each isolation cover 33 covers the part of each anchor rod 4 on the slope ground, thereby protecting it and reducing the possibility of the part of the anchor rod 4 on the ground being hit by external collisions, thus preventing the protective netting from loosening on the slope.
