Description

Technical Field

[0001] This invention relates to the field of debris flow prevention and control technology, and in particular to a debris flow blocking device. Background Technology

[0002] Debris flows are special types of floods that occur in mountainous areas or other deep valleys and rugged terrain, triggered by torrential rains or other natural disasters, carrying large amounts of mud, sand, and rocks. Debris flows are characterized by their suddenness, high velocity, large volume, large material capacity, and strong destructive power.

[0003] Currently, the most common debris flow control measures involve using retaining structures, such as cable mesh dams, grid dams, sieve dams, comb-tooth dams, and permeable arch dams. Existing dam-type retaining structures are all fixed projects, meaning their operational state is the same after completion, with the dam body always in a retaining state. However, after use, these existing retaining structures are affected by upstream debris flow accumulation, making them impossible to reopen. Engineering equipment cannot pass through the retaining area from downstream, hindering post-debris flow cleanup efforts. Summary of the Invention

Moreover, the retaining mechanism is designed to be openable and closable, allowing it to be reopened after the debris flow to facilitate dredging. The distance between the buffer mechanism and the side wall of the main structure is sufficient for the passage of dredging equipment, preventing dredging work from being affected.

Detailed Implementation

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this invention can be combined with each other. The described embodiments are merely some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this invention. The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] This invention provides a debris flow interception device, comprising:

[0041] Structural body 1, structural body 1 is a U-shaped structure, structural body 1 is set in the trench and is set along the length of the trench;

[0042] The barrier mechanism is set in the U-shaped groove of the structure body 1. The barrier mechanism is an openable and closable structure. The barrier mechanism is used to block the structure body 1. Water-permeable holes are provided on the barrier mechanism.

[0043] A buffer mechanism is located upstream of the barrier mechanism and in the middle of the main body 1. The distance between the buffer mechanism and the side wall of the main body 1 is sufficient for the passage of the dredging equipment.

[0044] In use, this invention involves modifying a trench and constructing a structural body 1 within it. The number of structural bodies 1 constructed is determined by the width of the trench, and multiple structural bodies 1 can be constructed along the length of the trench. The structural bodies 1 are arranged correspondingly along the length of the trench. A barrier mechanism is then installed within the structural body 1 to block debris flows. A buffer mechanism is installed upstream of the barrier mechanism to dissipate energy from the debris flow, reducing its impact and thus lowering the likelihood of damage. Furthermore, the barrier mechanism is designed to be openable and closable, allowing it to be reopened after a debris flow to facilitate dredging. The distance between the buffer mechanism and the sidewall of the structural body 1 is sufficient for dredging equipment to pass through, preventing disruption to dredging operations.

[0045] Furthermore, the barrier mechanism includes:

[0046] Mounting column 2 is fixedly installed on the opposite side walls of the structure body 1, and the mounting position is provided on the downstream side of the mounting column 2;

[0047] The baffle plate 3 is rotatably connected to the mounting column 2 via the mounting position, and the water permeable hole is opened on the baffle plate 3; when the two baffle plates 3 are in the closed state, they form a V-shaped structure, and the included angle between the two baffle plates 3 is 90°-150°.

[0048] The support assembly is fixedly installed on the side wall of the main structure 1 and located downstream of the mounting column 2. The support assembly is used to support the closed barrier plate 3.

[0049] By integrating the mounting column 2 with the main structure 1, the structural strength of the mounting column 2 can be improved, preventing damage to the mounting column 2 when impacted by debris flow, thus affecting the blocking effect of the barrier plate 3 on debris flow. Moreover, by limiting the angle between the two barrier plates 3, local damage to the barrier plate 3 due to concentrated force can be avoided after a debris flow. The barrier plate 3 is supported by the support components, which can prevent the barrier plate 3 from opening when impacted by debris flow.

[0050] Furthermore, to ensure that the installation of the support components does not affect the opening and closing of the barrier mechanism, the support components include:

[0051] Mounting base 4 is fixedly installed on the side wall of the structure body 1. There is a horizontal angle between the mounting base 4 and the structure body 1. The top of the end of the mounting base 4 away from the structure body 1 is provided with a mounting groove.

[0052] The support rod 5 has one end set in the mounting groove and connected to the mounting base 4 by a pin. The other end of the support rod 5 is fixedly connected to the support plate 6. The support plate 6 is in contact with the barrier plate 3, and the support rod 5 is set perpendicular to the barrier plate 3.

[0053] The support rod 5 is mounted on the mounting base 4 by a pin. When it is necessary to remove the support rod 5, simply remove the pin and take the support rod 5 out of the mounting slot.

[0054] Furthermore, the supporting components also include:

[0055] Adjusting seat 7 is slidably sleeved on support rod 5, and the adjusting seat 7 is connected and fixed to support rod 5 by a pin.

[0056] Movable plate 8 is located on the side of support plate 6 near barrier plate 3. Adjusting rod 9 is slidably installed on support plate 6. One end of adjusting rod 9 is fixedly connected to movable plate 8, and the other end of adjusting rod 9 abuts against adjusting seat 7. The distance between movable plate 8 and support plate 6 is 10cm-15cm.

[0057] After a debris flow occurs, the barrier plate 3 will adhere tightly to the support plate 6 under the impact of the debris flow, making it difficult to remove the support rod 5, thus affecting the opening of the barrier plate 3 and consequently the dredging work. Therefore, this invention uses a movable plate 8 to support the barrier plate 3 in the early stage. The movable plate 8 is limited by the adjusting rod 9 and the adjusting column, which can prevent the movable plate 8 from shifting when impacted by the debris flow. After the debris flow, the debris flow deposits upstream of the barrier plate 3 are less likely to deform after the water volume decreases. At this time, the pin on the adjusting seat 7 can be removed, and the position of the adjusting seat 7 can be changed to adjust the position of the movable plate 8, thus creating a certain gap between the movable plate 8 and the barrier plate 3. At this time, the position of the barrier plate 3 is not easily changed. At this time, simply rotating the support rod 5 can release the limitation between the support rod 5 and the barrier plate 3, making it convenient to open the barrier plate 3.

[0058] Furthermore, to improve the energy dissipation effect on debris flows, an arc-shaped guide plate 10 is fixedly installed on the side of the barrier plate 3 away from the support components, and the position of the arc-shaped guide plate 10 corresponds to that of the support components.

[0059] After the debris flow is first dissipated by the buffer mechanism, it impacts the barrier plates 3 from both sides of the buffer mechanism. Due to the inclined setting of the barrier plates 3, the barrier plates 3 can play a certain guiding role for the debris flow. Then, guided by the arc-shaped guide plate 10, the debris flow on the two barrier plates 3 can collide with each other to dissipate energy. Moreover, it can prevent the debris flow from directly impacting the joint of the two barrier plates 3, thus helping to maintain the stability of the barrier plates 3. In addition, the position of the arc-shaped guide plate 10 is set in correspondence with the support component, which can ensure the effective support of the support component for the barrier plates 3.

[0060] Furthermore, the buffer mechanism includes:

[0061] The mounting plate 11 is vertically fixed on the bottom wall of the structural body 1, and the mounting plate 11 has through holes.

[0062] The support beam 12 is slidably installed in the through hole. There is a notch on the side where the two baffles 3 are in contact. The notch on the baffle 3 in the closed state forms a sliding hole. The support beam 12 is slidably limited to the sliding hole.

[0063] An arc-shaped baffle 13 is fixedly installed at the upstream end of the supporting beam 12. A gap is provided between the bottom end of the arc-shaped baffle 13 and the bottom wall of the structure body 1, and the distance between the arc-shaped baffle 13 and the side wall of the structure body 1 is sufficient for the passage of the dredging equipment.

[0064] Spring 14 is disposed between the arc-shaped baffle 13 and the mounting vertical plate 11, and spring 14 is slidably sleeved on the supporting crossbeam 12. The two ends of spring 14 abut against the mounting vertical plate 11 and the arc-shaped baffle 13 respectively.

[0065] The arc-shaped baffle 13 is installed by mounting a vertical plate 11 and a supporting horizontal beam 12. The supporting horizontal beam 12 is aligned and limited by the barrier plate 3, which can ensure the stability of the supporting horizontal beam 12. The supporting horizontal beam 12 will not affect the opening and closing of the barrier plate 3. When the arc-shaped baffle 13 is impacted by a debris flow, it will dissipate energy by compression through spring 14, thus preventing the arc-shaped baffle 13 from being damaged by the impact. Moreover, under the weight of the supporting horizontal beam 12, the friction between the supporting horizontal beam 12 and the mounting vertical plate 11 and the barrier plate 3 can also achieve a certain energy dissipation effect.

[0066] Furthermore, to ensure the structural strength of the mounting vertical plate 11, a fixing beam 15 is fixedly connected to the top of the mounting vertical plate 11. The two ends of the fixing beam 15 are fixedly connected to the two mounting columns 2 respectively, and the fixing beam 15 is fixedly connected to the structural body 1.

[0067] Furthermore, to improve the buffering effect against debris flows, the buffering mechanism also includes an elastic support component disposed at the other end of the supporting beam 12. The elastic support component is fixedly installed on the structural body 1 and is used to buffer the supporting beam 12. The elastic support component includes:

[0068] Column 16 is located downstream of the supporting beam 12 and is fixedly installed in the middle of the bottom wall of the structural body 1.

[0069] The support base 17 is slidably sleeved on the support beam 12, and the support base 17 and the support beam 12 are in a limiting fit.

[0070] Guide post 18 is fixedly installed on column 16, and support base 17 is slidably sleeved on guide post 18;

[0071] Spring 19 is disposed between the support base 17 and the column 16, and spring 19 is slidably sleeved on the guide column 18. The two ends of spring 19 are in contact with the support base 17 and the column 16 respectively.

[0072] After the arc-shaped baffle 13 is impacted, the supporting beam 12 moves downstream. At this time, the supporting base 17 installed on the supporting beam 12 will move towards the column 16 under the action of the guide column 18, thereby compressing the second spring 19. Therefore, after the arc-shaped baffle 13 is impacted by the debris flow, both the first spring 14 and the second spring 19 will be compressed, thereby improving the buffering and energy dissipation effect of the debris flow.

[0073] The debris flow interception device provided by this invention operates as follows: After a debris flow occurs, the debris flow flows along the ditch into the structural body 1, first impacting the arc-shaped baffle 13. Springs 14 and 19 are used for buffering and energy dissipation. The arc-shaped baffle 13 also guides the debris flow, directing it to both sides. The channel within the structural body 1 narrows under the action of the arc-shaped baffle 13, causing the debris flow to become congested and reducing its velocity. The debris flow then impacts the interception plate 3, which is supported by a support assembly. The interception plate 3 and the arc-shaped guide plate 10 guide the debris flow, changing the direction of the debris flow on both sides, causing them to collide and dissipate energy, further reducing the velocity of the debris flow. Finally, the debris flow accumulates at the interception plate 3, thus blocking the debris flow. When dredging is required, simply adjust the position of the movable plate 8 to separate the movable plate 8 from the barrier plate 3, thereby facilitating the removal or rotation of the support rod 5, opening the barrier plate 3, allowing the dredging equipment to pass through, and facilitating the cleanup work after the mudslide.

[0074] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
