Description

Technical Field

[0001] This utility model relates to the field of soil and water conservation protection technology, specifically a soil and water conservation protective net fixing structure. Background Technology

[0002] Soil and water conservation refers to the prevention and control measures taken against soil erosion caused by natural factors and human activities. Soil and water conservation protection nets are important facilities used to prevent soil erosion and protect soil and vegetation.

[0003] Currently, soil and water conservation protection nets are usually fixed with nails or anchors. Although both nails and anchors can fix the protection nets, the size of the nails and anchors is generally fixed. However, the soil or rock in the slope may deform due to factors such as vibration, natural settlement or human activities, which may cause the nails or anchors to loosen or even fall off, thus causing the protection nets to fall off. Utility Model Content

[0004] This utility model proposes a fixing structure for soil and water conservation nets, which solves the problem that fixing nails or anchors used to fix soil and water conservation nets are easy to loosen, leading to the nets falling off.

[0005] To achieve the above objectives, this utility model proposes a soil and water conservation net fixing structure, including connecting anchor rods, multiple support plates, and a sliding top support mechanism disposed between the multiple support plates and capable of pushing the multiple support plates outward;

[0006] The connecting anchor is a tubular rod, and multiple support plates are arranged around the periphery of the connecting anchor, and the multiple support plates are slidably connected to the side wall of the connecting anchor in the horizontal direction.

[0007] The sliding support mechanism is installed inside the connecting anchor rod.

[0008] Preferably, the side wall of the connecting anchor rod is provided with a plurality of sliding holes, and the left and right side walls of the sliding holes are respectively provided with a plurality of anti-detachment sliders.

[0009] Preferably, the inner side of the connecting anchor rod is provided with a plurality of vertical connecting ridges, the connecting ridges being spaced apart from the sliding holes, and the inner side of the connecting ridges being provided with a plurality of vertical sliding grooves.

[0010] Preferably, the sliding top support mechanism includes a lead screw, a lifting tube, and an annular support block;

[0011] The lead screw rotates inside the connecting anchor rod, the lifting tube is sleeved outside the lead screw, and the lifting tube is threadedly connected to the lead screw;

[0012] The support block is provided in multiple parts, and the multiple support blocks are all sleeved on the outside of the lifting pipe, and the multiple support blocks are all fixed to the lifting pipe.

[0013] Preferably, the upper part of the support block is a columnar vertical part, and the lower part of the support block is a frustum-shaped guide part, with the small end of the guide part facing downward;

[0014] The vertical part is provided with a plurality of connecting sliders on its peripheral side, and the connecting sliders slide in the corresponding grooves.

[0015] Preferably, the inner side of the support plate is provided with a plurality of guide blocks along the vertical direction, and the guide blocks are provided corresponding to the support blocks;

[0016] The left and right sides of the guide block are respectively provided with two sliding grooves;

[0017] The support plate slides within the sliding hole, and the anti-detachment slider slides within the second sliding groove.

[0018] Preferably, the upper part of the inner side surface of the guide block is an inclined surface, and the inclined surface of the guide block abuts against the peripheral side surface of the guide portion.

[0019] Preferably, a base plate is fixed to the top of the connecting anchor rod, and the base plate has multiple fixing holes;

[0020] A through hole is formed at the center of the substrate, and a plurality of fixing holes are arranged around the through hole. The top end of the lead screw passes through the through hole, and the lead screw rotates relative to the substrate.

[0022] Preferably, the lead screw has a threaded connection to a fixing plate on the section near the top end, and the fixing plate is located on the base plate.

[0023] This utility model has the following beneficial effects:

[0024] 1. The sliding jacking mechanism, in conjunction with the guide jacking block, can push out multiple jacking plates simultaneously. After the multiple jacking plates are pushed out, they squeeze the soil or rock around the connecting anchor rod, thereby making the connecting anchor rod more firmly fixed in the slope.

[0025] 2. The fixing clamp and the base plate work together to clamp and fix the protective netting.

[0026] 3. Fixing nails can more firmly fix the connecting anchor rods in the slope, and at the same time prevent the connecting anchor rods from rotating during the rotation of the screw rods, which would affect the lowering of the support block driven by the lifting pipe.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0034] This utility model proposes a soil and water conservation net fixing structure, such as Figure 1 and Figure 2 As shown, it includes a connecting anchor rod 1, multiple support plates 2, and a sliding top support mechanism disposed between the multiple support plates 2 and capable of pushing the multiple support plates 2 outward. The connecting anchor rod 1 is a tubular rod, the multiple support plates 2 are arranged around the periphery of the connecting anchor rod 1, and the multiple support plates 2 are all slidably connected to the side wall of the connecting anchor rod 1 in the horizontal direction. The sliding top support mechanism is installed inside the connecting anchor rod 1.

[0035] like Figure 3 As shown, the side wall of the connecting anchor rod 1 is provided with multiple sliding holes 12, and multiple anti-detachment sliders 13 are respectively provided on the left and right side walls of the sliding holes 12.

[0036] like Figure 3 As shown, the inner side of the connecting anchor rod 1 is provided with multiple vertical connecting ridges 14, the connecting ridges 14 and the sliding holes 12 are spaced apart, and the inner side of the connecting ridges 14 is provided with multiple vertical sliding grooves 141.

[0037] like Figure 4As shown, the sliding top support mechanism includes a lead screw 4, a lifting tube 6, and an annular support block 7;

[0038] The lead screw 4 rotates inside the connecting anchor 1, and the lifting pipe 6 is sleeved outside the lead screw 4, and the lifting pipe 6 is threadedly connected to the lead screw 4;

[0039] Multiple support blocks 7 are provided, and all support blocks 7 are sleeved on the outside of the lifting pipe 6, and all support blocks 7 are fixed to the lifting pipe 6.

[0040] like Figure 4 As shown, the upper part of the support block 7 is a columnar vertical part 71, and the lower part of the support block 7 is a frustum-shaped guide part 72, with the small end of the guide part 72 facing downward.

[0041] like Figure 2 , Figure 3 and Figure 4 As shown, the vertical part 71 has multiple connecting sliders 711 on its peripheral side, and the connecting sliders 711 slide in the corresponding grooves 141.

[0042] like Figure 2 and Figure 5 As shown, the inner side of the support plate 2 is provided with a plurality of guide blocks 21 along the vertical direction, and the guide blocks 21 are provided in correspondence with the support block 7;

[0043] The left and right sides of the guide block 21 are respectively provided with sliding grooves 211;

[0044] The support plate 2 slides within the sliding hole 12, and the anti-detachment slider 13 slides within the second sliding groove 211.

[0045] The anti-detachment slider 13 and the sliding groove 211 work together to prevent the support plate 2 from detaching from the connecting anchor rod 1.

[0046] like Figure 2 and Figure 5 As shown, the upper part of the inner side surface of the guide block 21 is an inclined surface, and the inclined surface of the guide block 21 abuts against the peripheral side surface of the guide part 72.

[0047] First, drill holes at designated locations on the slope. Then, drive the connecting anchor rod 1 into the holes and rotate the screw rod 4. The screw rod 4 drives the lifting pipe 6 to move downwards. The lifting pipe 6 drives multiple support blocks 7 to move downwards. As the guide part 72 moves downwards, it pushes multiple guide top blocks 21 that are in contact with the guide part 72 outwards from the connecting anchor rod 1. Multiple support plates 2 are also pushed out. After the multiple support plates 2 are pushed out, they squeeze the soil or rock around the connecting anchor rod 1 tightly, thereby fixing the connecting anchor rod 1 more firmly in the slope.

[0048] like Figure 2 and Figure 3 As shown, a base plate 11 is fixed to the top of the connecting anchor rod 1, and multiple fixing holes 111 are provided on the base plate 11.

[0049] A through hole 112 is formed at the center of the substrate 11, and multiple fixing holes 111 are arranged around the through hole 112. The top end of the lead screw 4 passes through the through hole 112, and the lead screw 4 rotates relative to the substrate 11.

[0050] like Figure 1 As shown, a fixing nail 5 is inserted into the fixing hole 111, and the base plate 11 is fixed to the slope by the fixing nail 5.

[0051] The fixing nail 5 can more firmly fix the connecting anchor 1 in the slope body, and at the same time prevent the connecting anchor 1 from rotating during the rotation of the screw 4, which would affect the lifting pipe 6 driving the support block 7 to descend.

[0052] like Figure 1 As shown, the screw 4 near the top end is threadedly connected to a fixing plate 3, which is located on the base plate 11.

[0053] like Figure 4 As shown, a prism-shaped groove 41 is provided at the top of the lead screw 4.

[0054] Using this invention, holes are first drilled at designated locations on the slope. Then, the connecting anchor rod 1 is driven into the holes. Next, fixing nails 5 are driven into the fixing holes 111 on the base plate 11 to fix the base plate 11 to the slope. This also makes the connecting anchor rod 1 more firmly fixed in the slope. Then, an auxiliary tool is inserted into the slot 41 at the top of the lead screw 4, and the lead screw 4 is rotated by the auxiliary tool. The lead screw 4 drives the lifting tube 6 to move downward, and the lifting tube 6 drives multiple support blocks 7 to move downward. At the same time, the guide part 72 moves downward, and multiple guide tops that come into contact with the guide part 72 move downward. Block 21 is pushed outwards towards the connecting anchor rod 1, and multiple support plates 2 are pushed outwards accordingly until the vertical part 71 abuts against the lower part of the inner side of the guide block 21. At this time, the screw rod 4 is stopped from rotating. After the multiple support plates 2 are pushed out, they squeeze the soil or rock around the connecting anchor rod 1, thereby making the connecting anchor rod 1 more firmly fixed in the slope. Then, the protective net is placed on the top of the connecting anchor rod 1, and the top of the screw rod 4 passes through the mesh of the protective net. Finally, the fixing clamp 3 is screwed onto the top of the screw rod 4, and the fixing clamp 3 is pressed against the upper surface of the base plate 11 to clamp and fix the protective net.
