Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0028] like Figures 1-7The gabion net flood control and protection device shown is characterized by: comprising a first frame 1, a second frame 2, and a protective net cover 3. The protective net cover 3 is fixedly connected with four sets of auxiliary feet 21 with L-shaped cross sections. The protective net cover 3 has an L-shaped longitudinal section. The first frame 1 includes two sets of first columns 15 with L-shaped cross sections. The two sets of first columns 15 are connected to a first crossbar 20. The first column 15 is rotatably connected to a first support rod 4. The second frame 2 includes two sets of second columns 19 with L-shaped cross sections. The second column 19 is rotatably connected to a second support rod 5. The first support rod 4 and the second support rod 5 are rotatably connected. The second support rod 5 is threadedly connected to a threaded sleeve 17. When the threaded sleeve 17 is threadedly connected to both the first support rod 4 and the second support rod 5, the two support rods are coaxially connected. When the threaded sleeve 17 is threadedly connected to only the first support rod 4 or the second support rod 5, the first support rod 4 and the second support rod 5 can rotate relative to each other, thereby allowing the first protective net 6 and the second protective net 7 to be folded. Several sets of baffles 14 are fixedly connected to the first support rod 4 and the second support rod 5 respectively. The baffles 14 cooperate with the inner wall of the protective net cover 3. When the two support rods and the protective net cover 3 are in contact, the several sets of baffles 14 increase the contact area, allowing the net to be folded. The lateral pressure of the filler on the protective net is further transmitted to the outer frame. The first frame 1 and the first support rod 4 are jointly connected to the first protective net 6, and the second frame 2 and the second support rod 5 are jointly connected to the second protective net 7. The first protective net 6 and the second protective net 7 are rotatably connected. When folded for storage, the first protective net 6 and the second protective net 7 rotate towards each other. Compared with direct folding, this can reduce the deformation of the protective net and improve its durability. The first frame 1 is fixedly connected to a locking device, which includes an I-shaped block 8 and two sets of positioning blocks 16. The two sets of positioning blocks 16 are fixedly connected to the first column 15 and the second column 19, respectively. After the device is folded... The positioning block 16 and the I-shaped block 8 cooperate to further limit its shaking and prevent the device components from deforming due to bumps during transportation. Both sets of positioning blocks 16 are provided with convex grooves 9. The I-shaped block 8 is slidably connected to the inner wall of the convex groove 9. The positioning block 16 is slidably connected to the limiting rod 10. The positioning block 16 is provided with a cavity 18. The limiting rod 10 is fixedly connected to the limiting piece 11. The limiting rod 10 is sleeved with a spring 12. The spring 12 is fixedly connected to the inner wall of the cavity 18. The spring 12 abuts against the limiting piece 11. The I-shaped block 8 is provided with a limiting hole 13. The limiting rod 10 and the limiting hole 13 cooperate with each other to prevent the I-shaped block 8 and the positioning block 16 from separating due to vibration.

[0029] During storage and transportation, loosen the threaded sleeve 17 so that it connects only to one side of the first support rod 4 or the second support rod 5. At this time, the two support rods can rotate around the connection point, causing the first protective net 6 and the second protective net 7 to fold relative to each other, greatly reducing the volume of the device. After folding, insert the I-shaped block 8 into the convex groove 9 of the positioning block 16. Under the action of the spring 12, the limiting rod 10 automatically engages with the limiting hole 13 of the I-shaped block, forming a mechanical lock to prevent the frame from deforming or the components from separating due to bumps during transportation. After unfolding the device, tighten the threaded sleeve 17 to fix the two support rods coaxially, forming a stable support structure. The gaps between the first and second uprights 15 and the side wall of the protective net cover 3 and the four sets of L-shaped auxiliary feet 21 are filled by the L-shaped cross-section of the auxiliary feet 21 matching the uprights, which helps to quickly align and fix the position of the protective net, reducing manual calibration steps. When filling with stones, the baffles 14 on the support rods are in close contact with the inner wall of the protective net cover 3, which evenly distributes the lateral pressure of the stones to the frame, avoiding local stress concentration that could cause the net cover to deform. The split frame design enhances the bending strength through the L-shaped uprights and crossbars 20 and 22, while the precise positioning of the protective net by the auxiliary feet 21 further reduces the errors generated during installation.

[0030] The specific implementation process is as follows:

[0031] During transportation, the threaded sleeve is loosened so that it connects only to one side of the first or second support rod. At this time, the two support rods can rotate around the connection point, causing the first and second protective nets to fold relative to each other, significantly reducing the overall volume. After folding, the I-shaped block is inserted into the convex groove of the positioning block, and the limiting rod automatically engages with the limiting hole of the I-shaped block under the action of the spring, forming a mechanical lock, effectively preventing frame shaking or structural deformation caused by bumps during transportation.

[0032] During installation, tighten the threaded sleeve to fix the two support rods coaxially, forming a stable support structure. Embed the L-shaped first and second uprights into the gaps between the bottom protective net cover sidewall and the auxiliary feet to complete the initial positioning. Then, connect and fix the first frame, second frame, and top protective net cover with bolts. When filling with stones, the baffles on the support rods should be in close contact with the inner wall of the protective net cover to evenly transmit the lateral pressure of the filler to the frame, avoiding localized stress concentration that could cause the protective net to tear. After filling with stones, install the top protective net cover.
