Description

Technical Field

[0001] The utility model relates to the technical field of protective nets, in particular to a debris flow ditch mouth protective frame. Background Art

[0002] Debris flow disaster prevention and control project is a comprehensive and systematic project, which involves many factors and many prevention and control methods, but it can be summarized into two categories: geotechnical engineering measures and bioengineering measures. Geotechnical engineering measures can be summarized into four categories: interception, blocking, storage, and drainage. For example, the patent document with application number CN201910996608.7 discloses a debris flow valley ecological engineering protection system. By setting up a protection unit, an open blocking door can be opened to facilitate the discharge of debris flow through the drainage grid plate when a debris flow occurs and prevent the outflow of large rocks and soil.

[0003] However, in similar schemes mentioned above, the impact force of the debris flow is relatively large, and the protective net cannot provide buffering when impacted. In addition, the protective frame is not firmly connected to the ground, resulting in the entire protective frame being directly washed away, thus failing to play a protective role. In addition, the debris flow protection net is narrow, and large pieces of wood debris accumulate on one side of the protective frame, causing the debris flow riverbed to rise rapidly, thereby causing a secondary impact through the protective frame.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a debris flow gully mouth protection frame is proposed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a debris flow gully mouth protection frame, which solves the above-mentioned similar solutions proposed in the above-mentioned background technology. The impact force of the debris flow is relatively large, and the protection net cannot buffer when it is impacted, and the protection frame is not firmly connected to the ground, resulting in the entire protection frame being directly washed away, thereby failing to play a protective role. In addition, the debris flow protection net is narrow, and large pieces of tree impurities are accumulated on one side of the protection frame, causing the debris flow riverbed to rise rapidly, thereby causing the problem of secondary impact caused by passing through the protection frame.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a debris flow ditch mouth protection frame, comprising a support column, a buffer assembly and an anti-leakage assembly, the right end of the support column is connected to two groups of buffer rods, and the buffer assembly is located on the inner side of the buffer rod, and the buffer assembly includes a self-locking disk, a rotating shaft and a second protective net, the self-locking disks are fixed to the upper and lower ends of the buffer rod, and the rotating shaft is fixed between the two groups of the self-locking disks, and the second protective net is arranged around the outer side of the rotating shaft, the anti-leakage assembly is located at the rear end of the support column, and the anti-leakage assembly includes a connecting rod, a support rod and a filter net, the lower end of the support column is fixed with the connecting rod, and the end of the connecting rod away from the support column is fixed with the support rod, and the filter net is fixed to the right side of the support rod.

[0007] Furthermore, a plurality of groups of fixing rings are fixed between the support column and the buffer rod, and steel wire ropes are connected between the plurality of groups of fixing rings.

[0008] Furthermore, a first protective net is fixed below the steel wire rope, and the first protective net is formed by weaving and welding the steel wire mesh, and the second protective net is formed by weaving ultra-high molecular weight polyethylene wire.

[0009] Furthermore, the self-locking plate includes a gear plate, a movable plate and a rotating rod, and the rotating rod is fixed to the upper and lower ends of the rotating shaft, and the outer side of the rotating rod is slidably connected to the movable plate, and the gear plate is fixed to the outer side of the movable plate.

[0010] Furthermore, the movable disk forms a rotating structure through the rotating shaft and the rotating rod, and two ends of the second protective net are respectively wound around the outer sides of the two groups of rotating shafts.

[0011] Furthermore, the filter net is located at the rear end of the buffer rod, and two groups of the support columns and the buffer rod are symmetrically arranged about the vertical center line of the second protective net.

[0012] The utility model provides a debris flow ditch mouth protection frame, which has the following beneficial effects:

[0013] It can achieve buffering and unloading when the impact of debris flow is large, avoid the loose connection between the protection frame and the ground, avoid the entire protection frame being directly washed away, and prevent it from failing to play a protective role. In addition, when large pieces of tree debris accumulate on one side of the protection frame, causing the riverbed of the debris flow to increase, the impurities that pass through the protection net can be piled on both sides of the protection net, thereby improving the stability of the protection frame and avoiding secondary impact. The specific contents are as follows:

[0014] When the debris flow hits the protective net, the debris flow hits the second protective net. Since the second protective net has good toughness, it can unload the force through plastic deformation. After blocking the first wave, the traction of the debris flow drives the rotating shaft to rotate, causing the two sets of buffer rods to move backward, thereby widening the area of ​​the protective net so that the front side of the protective net can accommodate more impurities. When the impurities pass through the protective net, they will be blocked by the filter net, causing the impurities to accumulate at the rear end of the filter net. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figures 1 to 5As shown, a debris flow ditch mouth protection frame includes a support column 1, a buffer component 5 and an anti-leakage component 6. The right end of the support column 1 is connected to two groups of buffer rods 2. A plurality of fixing rings 3 are fixed between the support column 1 and the buffer rod 2, and a steel wire rope 31 is connected between the plurality of fixing rings 3. The fixing rings 3 and the steel wire rope 31 are used to strengthen the connection strength between the support column 1 and the buffer rod 2, thereby improving the impact resistance and avoiding being dispersed. The buffer component 5 is located on the inner side of the buffer rod 2, and the buffer component 5 includes a self-locking disk 501, a rotating shaft 502 and a second protective net 503. The buffer rod 2 The upper and lower ends are fixed with self-locking disks 501, and the retraction speed of the second protection net 503 can be controlled by the self-locking disks 501. The self-locking disks 501 include a gear disk 511, a movable disk 512 and a rotating rod 513, and the upper and lower ends of the rotating shaft 502 are fixed with rotating rods 513, and the outer side of the rotating rod 513 is slidably connected with the movable disk 512. The movable disk 512 forms a rotating structure through the rotating shaft 502 and the rotating rod 513. When subjected to a small traction, the movable disk 512 can rotate by itself, thereby pulling out the second protection net 503, and the outer side of the movable disk 512 is fixed with a gear disk 511. 11. When the second protection net 503 is pulled outward, it can drive the rotating shaft 502 to rotate. When impacted, the rotating shaft 502 and the rotating rod 513 rotate too fast to make the movable disk 512 deviate from the original track, so that the movable disk 512 and the gear disk are stuck. When impacted by a strong force, it automatically forms a self-locking state, similar to a seat belt that can lock the second protection net 503 when impacted, so as to form a strong resistance to mudslides. The rotating shaft 502 is fixed between the two sets of self-locking disks 501, and the second protection net 503 is arranged around the outer side of the rotating shaft 502, and the second protection net 503 It is woven with ultra-high molecular weight polyethylene wire. The flexible net can achieve buffering and unloading when the impact force of the debris flow is large through deformation, and the two ends of the second protective net 503 are wound around the outside of the two sets of rotating shafts 502, so that a structure similar to a reel is formed between the second protective net 503 and the buffer rod 2. When pulled by the debris flow, it can be slowly pulled out, thereby widening the area of ​​the protective net, so that the front side of the protective net can accommodate more impurities. The first protective net 4 is fixed below the wire rope 31, and the first protective net 4 is woven and welded by the wire mesh, which can improve the supporting strength of the protective net.

[0023] The anti-leakage component 6 is located at the rear end of the support column 1, and the anti-leakage component 6 includes a connecting rod 601, a support rod 602 and a filter screen 603. The lower end of the support column 1 is fixed with a connecting rod 601 for connecting the support rod 602 and the support column 1, and the end of the connecting rod 601 away from the support column 1 is fixed with a support rod 602 for fixing the filter screen 603. The right side of the support rod 602 is fixed with a filter screen 603. The filter screen 603 is located at the rear end of the buffer rod 2, so that impurities accumulate at the rear end of the protective screen, thereby improving the stability of the device, because the support column 1 and the buffer rod 2 are symmetrically arranged in two groups about the vertical center line of the second protective screen 503, the stability of the anti-leakage component 6 is improved, and secondary impact is avoided, because the connecting rod 601 connects the support column 1 and the support rod 602 underground, thereby improving the stability of the support column 1, avoiding the protective frame from being loosely connected to the ground, avoiding the entire protective frame from being directly washed away, and preventing it from failing to play a protective role.

[0024] In summary, when this type of debris flow ditch mouth protection frame is used, first, the connecting rod 601 is buried underground, and the support column 1, the support rod 602 and the connecting rod 601 are fixedly connected by welding. When the debris flow is pulled, the two groups of buffer rods 2 move backwards, which can drive the rotating shaft 502 to rotate, so that the second protection net 503 rolled into the buffer rod 2 is pulled out, thereby increasing the area of ​​the front end of the protection frame. When the debris flow strongly impacts the protection net, the second protection net 503 is quickly dragged, thereby driving the rotating shaft 502 to rotate quickly, and the rotating shaft 502 drives the rotating rod 513 and the movable disk 512 to rotate quickly, so that the movable disk 512 can rotate quickly. The disk 512 deviates from the original trajectory and gets stuck with the gear disk 511, thereby forming a self-locking state and forming a strong resistance to the debris flow. The debris flow hits the first protective net 4 and the second protective net 503. Since the second protective net 503 has good toughness, it can unload force and buffer through plastic deformation, thereby widening the area of ​​the second protective net 503, so that the front side of the protective net can accommodate more impurities, and the impurities will be blocked by the filter net 4 when passing through the inside of the two groups of protective nets, and the impurities will be accumulated between the filter net 4 and the protective net, thereby forming support for the rear end of the protective net, thereby improving the stability of the device.
