[0010] In the slope direction, the outer ends of the snow guard fences on the same side of different snow guard fence groups are extended in a manner of gradually increasing extension distances.

[0011] In one embodiment of the first aspect, the snow fence comprises:

[0012] A net frame and an interception net, wherein the interception net is installed on the net frame; wherein the interception net is a straw rope net.

[0025] The embodiments of the present application have the following advantages:

[0026] The present application provides an avalanche disaster protection device, wherein the snow fence group is composed of a pair of snow fences, each pair of snow fences gradually approaches each other in the slope direction and is staggered. This design helps to disperse the energy of the snow flow and reduce the impact of the snow flow on a single snow fence. In addition, multiple snow fence groups are arranged at intervals along the slope direction of the slope, which means that the snow fence groups are not arranged continuously, but at certain intervals. Such an arrangement helps to further disperse the energy of the snow flow and reduce the impact of the snow flow on the snow fence group, and further consume the kinetic energy of the snow flow by using the slope. Among them, when the snow flow slides down the slope, it will first encounter the upstream snow fence, and the snow flow will be blocked and piled up by the snow fence, and flow along the inclination direction of the current snow fence to the downstream snow fence, so that the snow flow will be further dispersed, reducing the degree of damage to a single snow fence. Obviously, in this way, the energy of the snow flow is weakened step by step, reducing the impact of the snow flow on the snow fence below. Furthermore, by staggering the snow fence groups and designing them to be gradually close together, the impact force of snow flow on a single snow fence can be reduced, thereby increasing the service life of the snow fence. In addition, due to the increased service life of the snow fence, the maintenance frequency and maintenance workload can be reduced, and the maintenance cost can be reduced.

[0027] The present application also relates to an avalanche disaster protection system. Since the above-mentioned avalanche disaster protection device has the above-mentioned technical effects, the avalanche disaster protection system including the avalanche disaster protection device should have the same technical effects, which will not be repeated here.

[0040] In the related art, avalanche is a natural phenomenon that occurs on snowy slopes with thick snow in snowy areas. Due to its suddenness, it often causes loss of life and property. In order to reduce the risk of avalanches, humans continue to explore the prevention and control of avalanches, and the engineering prevention and control technology of avalanches has also been continuously developed.

[0041] Through continuous engineering practice and exploration at home and abroad, four types of avalanche engineering prevention and control have been formed, namely, stabilization (snow stabilization grids, snow stabilization walls, snow stabilization earth steps, etc.), anti-avalanche corridors (snow guide banks, snow troughs, etc.), mitigation (energy dissipation earth cones, energy dissipation pits, snow breaking banks, etc.) and snow dams. The relevant research results have been widely used in areas prone to avalanches and have achieved certain results.

[0042] Usually, snow fences are mostly used for avalanche protection in mountainous areas. However, there are the following problems in actual use: snow fences are easily damaged by avalanches, have a short service life, require frequent repairs, and have a large workload for repair.

[0043] like Figure 1 As shown, in order to solve the above-mentioned technical problems, an embodiment of the present application provides an avalanche disaster protection device, which includes a snow fence group 100, wherein the number of the snow fence groups 100 is multiple, the multiple snow fence groups 100 are installed on the slope 200, and the multiple snow fence groups 100 are arranged at intervals along the slope direction of the slope 200; wherein the snow fence group 100 includes a pair of snow fences 110, the pair of snow fences 110 gradually approach each other in the slope direction, and the pair of snow fences 110 are staggered.

[0044] In these embodiments, the snow fence set 100 is composed of a pair of snow fence sets 100, and each pair of snow fences 110 gradually approaches each other in the slope direction.

[0045] For example, the ends of a pair of snow fences 110 that are close to each other are inner ends 112, and the ends of a pair of snow fences 110 that are far from each other are outer ends 111. Since each pair of snow fences 110 gradually approaches each other in the slope direction, the outer ends 111 of the snow fences 110 are located upstream of the inner ends 112, and each pair of snow fences 110 is in a figure eight shape. During an avalanche, the snow flow contacts the first snow fence group 100 and flows toward each other along the pair of snow fences 110 of the first snow fence group 100, thereby dispersing the snow flow and allowing the snow flow to flow from the openings formed by the inner ends 112 of the pair of snow fences 110 of the first snow fence group 100 to the snow fences 110 of the second snow fence group 100. If the snow fence 110 of one of the snow fence groups 100 is damaged by the impact, the snow flow will directly flow to the snow fence 110 of the next snow fence group 100 after consuming the energy.

[0046] It should be noted that the inner ends 112 of a pair of snow guard fences 110 of the same snow guard fence set 100 are staggered, which can prevent snow from flowing down directly without contacting the snow guard fences 110 .

[0047] When an avalanche hits the snow fence group 100, the load generated by its kinetic energy is first partially consumed by the buffering deformation of the snow fence 110 of the snow fence group 100, and the inclined snow fence 110 can be used to guide the next snow fence 110 to disperse the load, so that other snow fences 110 can participate in it and begin to bear the force, carry the load step by step, and finally achieve the smooth dissipation of the kinetic energy of the avalanche.

[0048] The avalanche disaster protection device provided by the present application is applied, and the snow fence group is composed of a pair of snow fence groups 100, and each pair of snow fences 110 gradually approaches each other in the slope direction and is staggered. This design helps to disperse the energy of the snow flow and reduce the impact of the snow flow on a single snow fence 110. In addition, multiple snow fence groups 100 are arranged at intervals along the slope direction of the slope surface 200, which means that the snow fence groups 100 are not arranged continuously, but have a certain interval. Such an arrangement helps to further disperse the energy of the snow flow and reduce the impact of the snow flow on the snow fence group 100, and further consume the kinetic energy of the snow flow by using the slope surface 200. Among them, when the snow flow slides down the slope, it will first encounter the upstream snow fence 110, and the snow flow will be blocked and piled up by the snow fence 110, and flow to the downstream snow fence 110 along the inclination direction of the current snow fence 110, so that the snow flow will be further dispersed, reducing the degree of damage to a single snow fence 110. Obviously, in this way, the energy of the snow flow is gradually weakened, reducing the impact of the snow flow on the lower snow fence 110. Furthermore, through the staggered arrangement and gradually approaching design of the snow fence group 100, the impact force of the snow flow on a single snow fence 110 can be reduced, thereby improving the service life of the snow fence 110. In addition, due to the improved service life of the snow fence 110, the maintenance frequency and maintenance workload can be reduced, and the maintenance cost can be reduced.

[0049] like Figure 1 As shown, in some embodiments, in the same snow fence group 100, the ends of a pair of snow fences 110 that are close to each other are inner ends 112, and the ends of a pair of snow fences 110 that are away from each other are outer ends 111; in the slope direction, the outer ends 111 of the snow fences 110 on the same side of different snow fence groups 100 are extended in a manner that the extension distance gradually increases.

[0050] In these embodiments, in the same snow fence group 100, the ends of a pair of snow fences 110 that are close to each other are inner ends 112, and the ends that are away from each other are outer ends 111. In the slope direction, the outer ends 111 of the snow fences 110 on the same side of different snow fence groups 100 are extended in a manner of gradually increasing extension distances, which helps to better disperse the snow flow, so that the snow flow is dispersed in the slope direction with different snow fence groups 100, reducing the amount of snow flow carried by a single snow fence group 100.

[0051] That is to say, the above arrangement means that the closer to the bottom (the low point of the slope), the farther the outer end 111 of the snow fence 110 extends. Such a design helps to better disperse the snow flow and reduce the impact of the snow flow on the facilities below.

[0052] For example, the snow fences 110 on the same side are arranged in parallel, and the lengths of the snow fences 110 on the same side gradually increase in the slope direction.

[0053] For ease of understanding, the inner end 112 of the snow fence 110 is arranged at a set straight line, and the set straight line extends along the slope direction. That is, in the slope direction, the outer end 111 of the snow fence 110 gradually moves away from the set straight line.

[0054] like Figure 2 and Figure 3 As shown, in some embodiments, the snow fence 110 includes a mesh frame and an interception net 114, and the interception net 114 is installed on the mesh frame; wherein the interception net 114 is a straw rope net.

[0055] In these embodiments, the net frame is fixed on the slope 200, and the interception net 114 is connected to the net frame. During an avalanche, the snow flow directly impacts the interception net 114. If the interception net 114 is a straw rope net, the straw rope net will produce a certain elastic-plastic deformation when subjected to external loads, and its components will absorb a part of the energy when deforming and when damage and deformation occur inside the material;

[0056] When the force on the rope net reaches its limit, the net frame structure begins to bear the load and the system is forced to work together. When the current rope net is unable to intercept the avalanche, the rope net will suffer irreversible damage, destruction and deformation, causing the rope net at this level to fail and be destroyed, but it will also absorb a large amount of kinetic energy from the avalanche in the process.

[0057] Obviously, the form of the straw rope net is simple, and the materials are mainly locally available, which is convenient for timely maintenance and replacement after an avalanche, reducing costs. It effectively alleviates the transportation difficulties in high mountain valley areas, and the problem of large-scale material transportation exacerbating energy consumption and carbon emissions.

[0058] It should be noted that since the straw rope net is easily damaged, it can reduce the impact of snow flow on the net frame. In other words, after a snowstorm, only the straw rope net needs to be repaired.

[0059] Of course, in other embodiments, the interception net 114 is not limited to a straw rope net, but can also be set to a hemp net, a bamboo net, etc.

[0060] It should be noted that due to the large mesh pores of the straw rope net, the straw rope net only bears part of the load, thereby diverting the snow flow to reduce the impact of the snow flow on the straw rope net, which is conducive to extending its service life.

[0061] like Figure 2 and Figure 3 As shown, in some embodiments, the net frame includes a column 116, a first support rope 113 and a second support rope 115. The number of columns 116 is multiple, and the multiple columns 116 are arranged in parallel; the tops of the multiple columns 116 are connected in series through the first support rope 113, and the bottoms of the multiple columns 116 are connected in series through the second support rope 115.

[0062] In this embodiment, a plurality of columns 116 are arranged in parallel, and the columns 116 are the main supporting structure of the snow fence 110, and are used to fix the interception net 114. The tops of the plurality of columns 116 are connected in series by the first supporting rope 113, which can improve the stability between the columns 116 and ensure the overall firmness of the snow fence 110. The bottoms of the plurality of columns 116 are connected in series by the second supporting rope 115, which can also improve the stability between the columns 116 and ensure the stability of the snow fence 110 under the impact of snow flow, and the interception net 114 can be fixed on the first supporting rope 113 and the second supporting rope 115 to improve the connection strength of the interception net 114. Obviously, the structure of the net frame is relatively simple, which is convenient for daily maintenance.

[0063] like Figure 3 As shown, in some embodiments, the snow fence 110 includes a tying rope 117 , and the intercepting net 114 is tied and connected to the net frame by the tying rope 117 .

[0064] In this embodiment, the binding ropes 117 are used to fix the intercepting net 114 to the net frame to facilitate the disassembly and assembly of the intercepting net 114.

[0065] For example, the binding rope 117 may be made of elastic material so as to better adapt to changes in external conditions and help intercept snow flows.

[0066] For example, the net frame is usually a frame made of metal or weather-resistant material to support the entire structure. The interception net 114 is used to intercept and guide the direction of snow. The binding rope 117 is used to connect the parts of the net and the net frame to ensure the overall stability of the structure.

[0067] like Figure 2 As shown, in some embodiments, the distance between adjacent columns 116 is 8m-10m.

[0068] In these embodiments, the distance between adjacent columns 116 is set to 8 meters to 10 meters, which is a reasonable choice based on structural stability and cost-effectiveness. The selection of this spacing mainly considers the following factors:

[0069] The distance between the columns 116 should not be too long, otherwise the stability of the entire structure may be reduced. In particular, in the case of strong winds and a large amount of snow, too large a spacing may cause the mesh surface to deform or be damaged.

[0070] Setting a shorter spacing will increase the number of columns 116, thereby increasing construction costs. Therefore, under the premise of ensuring structural stability, choosing a longer spacing helps to reduce costs. Among them, the snow flow will exert pressure on the interception net 114, especially when the amount of snow is large. The longer spacing means that the interception net 114 needs to withstand greater pressure. Of course, in actual applications, appropriate adjustments need to be made based on local climate conditions, snow forecasts, and specific geographical locations.

[0071] For example, the distance between adjacent columns 116 is 8 m. Of course, in other embodiments, the distance between adjacent columns 116 is 8.5 m, 9 m, 9.5 m, 10 m, and so on.

[0072] like Figure 2 As shown, in some embodiments, the mesh shape of the interception net 114 includes any one or more of the following shapes: rectangle, diamond, triangle, ellipse, circle, honeycomb and pentagon.

[0073] In these embodiments, these different mesh shapes can be selected according to specific application requirements. For example, for the snow fence 110, factors such as mesh strength, snow interception efficiency, and wind resistance may be given priority. Diamond and rectangular meshes may be more common choices because diamond and rectangular meshes can provide sufficient interception area while maintaining good structural stability and wind resistance.

[0074] In some embodiments, posts 116 include any one or more of the following: wooden stakes and metal poles.

[0075] For example, the column 116 can be a metal rod; of course, in other embodiments, it can also be set as a wooden stake. If the column 116 is set as a wooden stake, the material is mainly locally available, which is convenient for timely maintenance and replacement after an avalanche.

[0076] In some embodiments, the height of the snow fence 110 is 3m-5m.

[0077] In these embodiments, the snow fence 110 and the slope 200 are vertically arranged, and such a height range is mainly for effectively intercepting and managing snow accumulation while taking into account the stability and cost-effectiveness of the structure.

[0078] A taller snow fence 110 generally requires more materials and a more complicated installation process, which increases costs. Therefore, it is important to select a suitable height to achieve the best cost-effectiveness ratio. In actual applications, the specific height of the snow fence 110 may be adjusted according to local climate conditions (such as average snow depth), terrain characteristics (such as wind direction and wind speed), and the intended protection target (such as roads, buildings, etc.).

[0079] Exemplarily, the height of the snow fence 110 is 3 m. Of course, in other embodiments, the height of the snow fence 110 is 3.5 m, 4 m, 4.5 m, 5 m, etc.

[0080] For example, the height of the snow fence 110 gradually increases on the slope.

[0081] In some embodiments, the present application further provides an avalanche disaster protection system, which includes an avalanche disaster protection device as described in any one of the above embodiments.

[0082] Since the above-mentioned avalanche disaster protection device has the above-mentioned technical effects, the welding system including the avalanche disaster protection device should have the same technical effects, which will not be repeated here.

[0083] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0084] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0085] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
