Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective netting technology, and in particular to a debris flow protective netting device. Background Technology
[0002] Debris flows are special types of floods caused by precipitation (heavy rain, glacial meltwater, snowmelt) in valleys or on mountain slopes, carrying large amounts of solid materials such as mud, sand, rocks, and boulders. Their water and sand accumulation processes are very complex and are the product of the combined effects of various natural and / or human factors. Debris flows are characterized by their suddenness, high velocity, large flow rate, large material capacity, and strong destructive power. Debris flows often destroy transportation facilities such as highways and railways, and even villages and towns, causing huge losses. In order to reduce the degree of damage caused by debris flows, protective nets are erected in areas prone to debris flows. These nets can intercept debris flows and achieve a certain degree of protection.
[0003] Commonly used protective nets for intercepting debris flows have poor stability during installation. Since the ground where they are installed is mostly soil, the connection between the net and the ground is not strong enough, and the net is prone to tipping over when impacted. Although the net itself has a certain degree of elasticity, the impact of debris flows is significant, and the net is easily damaged at the moment of impact. Once the net is damaged, it cannot effectively intercept debris flows. Therefore, this application proposes a debris flow protection net device. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a debris flow protection net device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a debris flow protection net device, comprising:
[0006] Embedded plate, the embedded plate is set as a rectangular plate structure;
[0007] Two columns are provided and fixedly installed at the middle position on both sides of the top of the embedded plate;
[0008] An annular groove is formed on the column;
[0009] The buffer mechanism is fitted into the annular groove on the column;
[0010] The first protective netting is erected between two pillars;
[0011] The steel cable is fixedly connected to the side of the first protective net and is inserted into the buffer mechanism;
[0012] The guardrail is installed horizontally in a U-shape behind the first protective netting, with both ends of the guardrail fixedly connected to the inner sides of two upright posts.
[0013] The second protective netting is laid vertically on the protective pole.
[0014] Furthermore, annular grooves are provided at the top, middle, and bottom positions of the two columns, and six buffer mechanisms are provided. The six buffer mechanisms are respectively fitted into the annular grooves on the two columns. Six steel cables are provided, and the six steel cables are respectively fixedly connected to the top, middle, and bottom positions on both sides of the first protective net, and the six steel cables are respectively inserted into the six buffer mechanisms.
[0015] Furthermore, the buffer mechanism includes a rotating ring, a fixed rod, a spring, and a circular ring. The rotating ring is rotatably fitted into an annular groove on the column. The fixed rod is horizontally set and fixedly installed on the front side of the rotating ring. A buffer cavity is opened at the end of each fixed rod away from the first protective net, and an opening communicating with the buffer cavity is opened at the end of each fixed rod close to the first protective net. The circular ring is movably inserted into the opening of the buffer cavity. The spring is fixedly connected to the side of the circular ring located inside the buffer cavity, and the other end of the spring contacts the inner wall of the buffer cavity but is not connected. A countersunk hole is opened at the top of the circular ring, and a limit bolt is threaded into the countersunk hole.
[0016] Furthermore, the end of each steel cable away from the first protective net extends through the opening into the buffer cavity and through the ring inside it. A buckle is fixedly connected to the end of each steel cable that passes through the ring, and the limiting bolt on each ring passes through the buckle at the end of the steel cable.
[0017] Furthermore, four sets of guardrails are installed, with the four guardrails installed at equal intervals from top to bottom between two posts, and a second protective net is laid on the front side of the four sets of guardrails.
[0018] Furthermore, the guardrail also includes:
[0019] The reinforcement rods consist of five sets, which are vertically and evenly connected between the four protective rods. The back of the second protective net is attached to the five sets of reinforcement rods.
[0020] Furthermore, the height of the second protective net is less than the height of the first protective net, and the horizontal height of the bottom of the second protective net is higher than the horizontal height of the bottom of the first protective net.
[0021] The embedded plate also includes:
[0022] Furthermore, there are four sets of rear support rods, which are symmetrically installed at the two corners at the top rear end of the embedded plate, and the top ends of the four rear support rods are respectively fixedly connected to the rear side of the two columns.
[0023] The beneficial effects of this utility model are:
[0024] 1. When the first protective net is impacted by a debris flow, it will move closer to the second protective net behind it. The steel cables on both sides of the first protective net will pull the buffer mechanism to rotate within the annular groove on the column. Under the impact of the debris flow, the steel cables on both sides of the first protective net will pull the ring to move within the buffer cavity of the fixed rod. As the ring gradually moves towards the inner end of the buffer cavity, it will compress the spring. During the compression process, the spring will dissipate part of the impact force on the first protective net, thereby effectively reducing the destructive force caused by the debris flow at the moment of contact with the first protective net, thus protecting the first protective net and preventing it from being damaged and unable to intercept the debris flow normally.
[0025] 2. After being intercepted by the second protective net, some of the debris flow passing through the first protective net can flow under the second protective net, which can effectively reduce the pressure on the second protective net. The flow velocity of the debris flow passing through the second protective net can be slowed down to a certain extent, thereby reducing the destructive power of the debris flow.
[0026] 3. By installing a pre-embedded plate below the ground, the stability of the column can be greatly improved. A large number of rocks will be swept up in the debris flow. When the debris flow comes into contact with the first protective net, the rocks in the debris flow will be intercepted and accumulate in front of the first protective net. In this way, the rocks will press on the front end of the pre-embedded plate. Under the action of the weight of the rocks, the pre-embedded plate is not easy to tilt up, thereby increasing the overall stability of the device. Attached Figure Description

[0040] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0041] Please see Figure 1 and Figure 7 This utility model provides a technical solution: a debris flow protection net device, including a pre-embedded plate 11, which is a rectangular plate structure. Columns 12 are fixedly installed at the middle positions of both sides of the top of the pre-embedded plate 11. An annular groove 14 is opened on the column 12, and a buffer mechanism 2 is fitted inside the annular groove 14. A first protective net 31 is erected between the two columns 12. A steel cable 32 is fixedly connected to the side of the first protective net 31 and passes through the buffer mechanism 2. A U-shaped protective rod 41 is horizontally arranged behind the first protective net 31, with both ends of the protective rod 41 fixedly connected to the inner sides of the two columns 12. A second protective net 43 is vertically laid on the protective rod 41.
[0042] See Figure 1 and Figure 7 Annular grooves 14 are provided at the top, middle and bottom positions of the two columns 12. Six buffer mechanisms 2 are provided, and the six buffer mechanisms 2 are respectively fitted into the annular grooves 14 on the two columns 12. Six steel cables 32 are provided, and the six steel cables 32 are respectively fixedly connected to the top, middle and bottom positions on both sides of the first protective net 31, and the six steel cables 32 are respectively inserted into the six buffer mechanisms 2.
[0043] See Figure 6 and Figure 7 The buffer mechanism 2 includes a rotating ring 21, a fixed rod 22, a spring 24, and a circular ring 23. The rotating ring 21 is rotatably sleeved in the annular groove 14 on the column 12. The fixed rod 22 is horizontally arranged and fixedly installed on the front side of the rotating ring 21. A buffer cavity 26 is opened at the end of each fixed rod 22 away from the first protective net 31, and an opening communicating with the buffer cavity 26 is opened at the end of each fixed rod 22 near the first protective net 31. The circular ring 23 is movably inserted into the opening of the buffer cavity 26. The spring 24 is fixedly connected to the side of the circular ring 23 located inside the buffer cavity 26, and the other end of the spring 24 contacts the inner wall of the buffer cavity 26 but is not connected. A countersunk hole is opened at the top of the circular ring 23, and a limit bolt 25 is threaded into the countersunk hole. When the first protective net 31 is subjected to... When impacted by a debris flow, the first protective net 31 moves closer to the second protective net 43 behind it. The steel cables 32 on both sides of the first protective net 31 pull the buffer mechanism 2 to rotate within the annular groove 14 on the column 12. Under the impact of the debris flow, the steel cables 32 on both sides of the first protective net 31 pull the ring 23 to move within the buffer cavity 26 of the fixed rod 22. As the ring 23 gradually moves towards the inner end of the buffer cavity 26, it compresses the spring 24. During the compression process, the spring 24 relieves part of the impact force on the first protective net 31, thereby effectively reducing the destructive force caused by the debris flow at the moment of contact with the first protective net 31, thus protecting the first protective net 31 and preventing it from being damaged and unable to intercept the debris flow properly.
[0044] See Figure 6 and Figure 7 Each steel cable 32 has one end away from the first protective net 31, which extends through the opening into the buffer cavity 26 and through the ring 23 inside. Each end of each steel cable 32 that passes through the ring 23 is fixedly connected to a buckle 33. The limiting bolt 25 on each ring 23 passes through the buckle 33 at the end of the steel cable 32. By inserting the limiting bolt 25 into the buckle 33 at one end of the steel cable 32, the steel cable 32 and the ring 23 can be connected together, thereby preventing the steel cable 32 from detaching from the buffer assembly.
[0045] See Figure 2 and Figure 3 The protective rods 41 are set in four sets, and the four protective rods 41 are installed at equal intervals from top to bottom between the two columns 12. The second protective net 43 is laid in front of the four sets of protective rods 41. The four sets of protective rods 41 can lay the second protective net 43 more stably, so that the second protective net 43 is located behind the first protective net 31. In this way, the second protective net 43, together with the first protective net 31, can play a more effective role in intercepting debris flows.
[0046] See Figure 2 and Figure 3 Five sets of vertical reinforcing rods 42 are evenly connected between the four protective rods 41. The back of the second protective net 43 is attached to the five sets of reinforcing rods 42. The reinforcing rods 42 and the protective rods 41 can increase the impact resistance of the second protective net 43. Under the action of the reinforcing rods 42 and the protective rods 41, the second protective net 43 is not prone to excessive deformation.
[0047] See Figure 1 and Figure 2 Five sets of reinforcing rods 42 are provided, and the five sets of reinforcing rods 42 are vertically and evenly connected. The height of the second protective net 43 is less than the height of the first protective net 31, and the horizontal height of the bottom of the second protective net 43 is higher than the horizontal height of the bottom of the first protective net 31. A space is reserved between the bottom of the second protective net 43 and the ground. After the debris flow passing through the first protective net 31 is intercepted by the second protective net 43, some of the debris flow can flow under the second protective net 43, thereby effectively reducing the pressure on the second protective net 43. The flow velocity of the debris flow passing through the second protective net 43 can be slowed down to a certain extent, thereby reducing the destructive force of the debris flow.
[0048] See Figure 1 and Figure 2 At the two corners of the top of the rear end of the embedded plate 11, two inclined rear support rods 13 are fixedly connected. The top ends of the four rear support rods 13 are fixedly connected to the rear side of the two columns 12. The rear support rods 13 can support the columns 12. When the first protective net 31 is impacted by the mudslide and the impact force is transmitted to the columns 12, the rear support rods 13 behind the columns 12 can enhance the impact resistance of the columns 12 and prevent the columns 12 from tilting due to the impact.
