Description

Technical Field

[0001] This utility model relates to the field of disaster prevention and mitigation equipment, specifically to a debris flow protection net for slope engineering. Background Technology

[0002] Debris flows typically occur after heavy rain. When a large amount of precipitation cannot be absorbed by the soil and vegetation, surface water accumulates and rapidly slides down the slope. During this slide, the water carries loose mud, rocks, and vegetation, forming a debris flow. Earthquakes, vegetation destruction, and human engineering activities can also trigger debris flows. Due to the suddenness and destructive power of debris flows, protecting downstream people, infrastructure, transportation routes, and urban safety is crucial. Traditional protective measures such as dams, canals, and steep slope management are not flexible or economical enough to deal with sudden large-scale debris flows. Therefore, with the advancement of materials and technology, debris flow protection nets have begun to be widely used.

[0003] Debris flow protection nets are typically made of high-strength steel wire mesh or synthetic materials and can be constructed in potentially dangerous landslide areas, gullies, and hillsides. Their function is to intercept and slow down debris flows, capture flowing rocks and large soil fragments, thereby reducing and avoiding direct impact on downstream areas. However, during debris flows, large rocks or debris may occasionally fall, further causing significant casualties and economic losses. Utility Model Content

[0004] The purpose of this invention is to provide a debris flow protection net for slope engineering, which can solve the problems existing in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a debris flow protection net for slope engineering, comprising two debris-blocking nets, each of which is hinged at both ends with a long strand and a short strand, the other end of the long strand is hinged with a composite bolt, the other end of the short strand is hinged with a fixing bolt, the two debris-blocking nets are hinged together with one end of the long strand facing each other, and the composite bolt and the fixing bolt are both fixed at the slope;

[0006] The composite bolt is hinged to one end of two hook rods, and the other ends of the two hook rods are respectively connected to the two ends of the hook block. Each hook block is fitted with another long stranded cable hinged to the net. The hook block and hook rod cooperate to limit the long stranded cable.

[0007] Optionally, the hook block includes a first limiting rod, a second limiting rod, a connecting rod, and a U-shaped block. The two hook rods hinged by the same composite bolt are provided with adjustable slide rails on their opposite faces. The two ends of the first limiting rod and the second limiting rod are slidably connected to the adjustable slide rails of the two hook rods, respectively. A connecting rod is provided at the first limiting rod and the second limiting rod. The first limiting rod and the second limiting rod are sleeved by the U-shaped block. The connecting rod passes through the first limiting rod, the second limiting rod, and the U-shaped block to connect the first limiting rod, the second limiting rod, and the U-shaped block in series.

[0008] Optionally, the U-shaped block includes a pressing block and a control spring. Each end of the control spring is provided with a pressing block. The two pressing blocks are respectively connected to the outer sides of the first limiting block and the second limiting rod. The distance between the pressing blocks is adjusted by the extension and retraction of the control spring, thereby controlling the distance between the first limiting block and the second limiting rod.

[0009] Optionally, the connecting rod has a limit block at one end near the second limiting rod.

[0010] Optionally, the surface of the debris-blocking net is provided with a plurality of diamond-shaped drainage outlets.

[0011] Optionally, the short strands of the debris-blocking net are arranged in a crisscross pattern.

[0012] Beneficial effects: 1. The hook block of this utility model can limit the long cable connected to another debris-blocking net, so that the two debris-blocking nets can be connected to each other. When the debris flow passes through the debris-blocking net, the debris-blocking net can filter the debris in the debris flow and the water can be discharged normally. When encountering large or many debris, after the first or second limiting rod of the hook block breaks, the end of the debris-blocking net with the long cable will move towards the end with the short cable, thereby stopping contact with the debris flow and wrapping and collecting the already intercepted debris, which can prevent the debris-blocking net from failing due to the increase of debris in the future.

[0013] 2. The U-shaped blocks of this utility model facilitate the cleaning of debris inside the debris-blocking net by operators after a debris flow. If the connecting block is not broken, the two U-shaped blocks can be separated from the connecting block, allowing the ends of the two debris-blocking nets with long ropes to move towards the ends with short ropes, thus facilitating the cleaning of debris inside the debris-blocking net and extending the service life of the device.

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, a debris flow protection net for slope engineering includes two debris-blocking nets 1. The surface of the debris-blocking net 1 is provided with several diamond-shaped drainage outlets. Each debris-blocking net 1 has a long cable 21 and a short cable 31 hinged to both ends. The other end of the long cable 21 is hinged to a composite bolt 2, and the other end of the short cable 31 is hinged to a fixing bolt 3. The short cables 31 hinged to the same debris-blocking net 1 are arranged in a crisscross manner. The ends of the long cables 21 hinged between the two debris-blocking nets 1 are opposite to each other. The composite bolt 2 and the fixing bolt 3 are both fixed at the slope.

[0021] Two hook rods 4 are hinged at one end of the same composite bolt 2. A hook block 41 is provided at the other end of the two hook rods 4 hinged at the same composite bolt 2. The two ends of the hook block 41 are respectively connected to the two hook rods 4 hinged at the same composite bolt 2. Each hook block 41 is sleeved with another long stranded cable 21 hinged to the other net 1. The hook block 41 and the hook rod 4 cooperate to limit the long stranded cable 21.

[0022] Both barrier nets 1 can use the hook rod 4 and hook block 41 connected to the other barrier net 1 to limit the long winch 21 connected to them. At the same time, by determining the relative position of the hook block 41 and the control rail 44, the two barrier nets 1 can cooperate with each other to intercept the debris flow in the target area.

[0023] The hook block 41 includes a first limiting rod 411, a second limiting rod 412, a connecting rod 413, and a U-shaped block 42. Both hook rods 4 are provided with an adjustment slide rail 44 on their opposite sides. The two ends of the first limiting rod 411 and the second limiting rod 412 are slidably connected to the adjustment slide rails 44 of the two hook rods 4. A connecting rod 413 is provided at the first limiting rod 411 and the second limiting rod 412. The first limiting rod 411 and the second limiting rod 412 are sleeved by the U-shaped block 42. Multiple connecting rods 413 are provided. Each connecting rod 413 passes through the first limiting rod 411, the second limiting rod 412, and the U-shaped block 42 to connect the first limiting rod 411, the second limiting rod 412, and the U-shaped block 42 in series. A limiting block 423 is provided at the end of the connecting rod 413 near the second limiting rod 412.

[0024] By adjusting the positions of the first limiting rod 411 and the second limiting rod 412 at the control slide rail 44, and after the first limiting rod 411 and the second limiting rod 412 are in suitable positions, the position between the first limiting rod 411 and the control slide rail 44 at the two hooking rods 4 is fixed. Then, the U-shaped block 42 connects the first limiting rod 411 and the second limiting rod 412. At this time, the positions of the first limiting rod 411, the second limiting rod 412 and the U-shaped block 42 are determined, and the position of the hooking block 41 is determined. Both hooking blocks 41 are implemented in this way, and then the two debris-blocking nets 1 are combined and supported. When large or many debris fall into the debris-blocking net 1, the second limiting rod 412 will break due to the increase in bearing capacity, and then the hooking block 41 and the hooking rod 4 will lose their support for the other debris-blocking net. The long winch 21 connected to the barrier net 1 is limited, so the end of the barrier net 1 with the long winch 21 hinged to it will move towards the end of the barrier net 1 with the short winch 31 hinged to it. At the same time, the debris in the barrier net 1 will also leave the debris flow area, thereby avoiding the accumulation of debris and causing the barrier net 1 to break. This also prevents the collected debris from falling back down, thus achieving the function of reducing the impact of the debris flow. At the same time, multiple of these devices are set in the debris flow area, which can effectively protect against the debris flow.

[0025] like Figure 4 As shown, the U-shaped block 42 includes a pressing block 421 and a control spring 422. A pressing block 421 is provided at each end of the control spring 422. The two pressing blocks 421 are respectively connected to the outer side of the first limiting block 423 and the second limiting rod 412. The distance between the pressing blocks 421 is adjusted by the extension and retraction of the control spring 422, thereby controlling the distance between the first limiting block 423 and the second limiting rod 412.

[0026] The operator can control the distance between the squeezing blocks 421 at both ends of the control spring 422 inside the U-shaped block 42. After the U-shaped block 42 is sleeved on the first limiting block 423 and the second limiting rod 412, the operator can use the shape of the squeezing blocks 421 and the control spring 422 to provide clamping force on the first limiting block 423 and the second limiting rod 412. This is in the case where the position of the first limiting rod 411 and the control slide rail 44 is determined, but the position of the second limiting rod 412 and the control slide rail 44 is not determined.

[0027] When the U-shaped block 42 is connected to the first limiting rod 411 and the second limiting rod 412, the hooking block 41 and the hooking rod 4 cooperate to limit the long cable 21 connected to the other debris barrier 1. After the U-shaped block 42 is moved out, when the position between the first limiting rod 411 and the second limiting rod 412 is not fixed, the second limiting rod 412 slides along the regulating slide rail 44 until the second limiting rod 412 contacts the limiting block 423. Then the hooking block 41 and the hooking rod 4 can no longer limit the long cable 21 connected to the other debris barrier 1. Then the end of the debris barrier 1 with the long cable 21 hinged will move towards the end of the debris barrier 1 with the short cable 31 hinged. Then the debris in the two debris barriers 1 can be cleaned by the operator located near the fixing bolt 3 and the composite bolt 2, thereby effectively extending the service life of the debris barrier 1.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. For those skilled in the art, after learning the contents of the present utility model, they can make several equivalent changes and substitutions without departing from the principle of the present utility model. These equivalent changes and substitutions should also be considered to fall within the protection scope of the present utility model.
