[0052] Referring to Figure 3 The snow breaking pile 1 is made of aluminum alloy profile, the upper part of the snow breaking pile 1 is provided with a first fixing hole 12, the lower part is provided with a second fixing hole 13, and the top is provided with a first snow cover 11, the bottom surface of the first snow cover 11 is provided with a connecting rod, the connecting rod is provided with a fixing hole 111, and the snow breaking pile 1 is connected with the stabilizing column 2 through the two fixing holes.

[0053] Referring to Figure 4 The stabilizing column 2 is a round galvanized steel pipe, the upper part is provided with a third fixing hole 22, the lower part is provided with a fourth fixing hole 23, the middle part is provided with a plurality of mounting holes 25, and the top is provided with a second snow cover 21, the bottom surface of the second snow cover 21 is provided with a connecting rod, and the connecting rod is provided with a fixing hole 211.

[0054] The snow breaking pile 1 and the stabilizing column 2 are fixed by fasteners, the fasteners are fixed by passing through the first fixing hole 12 and the third fixing hole 22, and the fasteners are fixed by passing through the second fixing hole 13 and the fourth fixing hole 23; the snow breaking pile 1 and the stabilizing column 2 are fixed on the slope surface by the concrete foundation 6. When the fasteners fix and connect the snow breaking pile 1 and the stabilizing column 2, the fixing holes 111 and the fixing holes 211 of the two snow covers are passed through at the same time, the first snow cover 11 and the second snow cover 21 are fixed on the snow breaking pile 1 and the stabilizing column 2, rain and snow and sundries are prevented from entering the column body of the snow breaking pile 1 and the stabilizing column 2, and the service life of the column body is prolonged.

[0059] The guide snow plate can utilize the wave-shaped plate discarded after the wave-shaped beam guardrail is removed, and the wave-shaped plate can be a two-wave wave-shaped plate or a three-wave wave-shaped plate. Utilizing the discarded wave-shaped plate can not only reduce the cost of the device, but also help to improve the utilization rate of the discarded wave-shaped plate and protect the environment.

[0060] When the avalanche disaster occurs, the snow body sliding from a high place collides with the avalanche protection device in a static state. Since the collision time is short and the inertia is large, the guide snow plate 5 can guide the snow to release energy when blocking the snow. The snow-breaking pile 1, the stabilizing column 2 and the supporting column 3 constituting the protection device are fixed on the slope surface through the foundation, and are unified as a whole by means of the wave-shaped plate, and have high strength. The avalanche is blocked and decelerated, the potential energy is reduced, the guide snow plate 5 can locally disperse the avalanche, further weakening the energy of the avalanche, so that the avalanche stops far away from the road, and the effect of protecting the road from being buried by the avalanche is realized.

[0061] Embodiment 2

[0062] The difference between this embodiment and embodiment 1 is the structure of the guide snow plate and the supporting column. In this application, a plurality of guide snow plates are arranged at intervals from top to bottom and connected with the supporting column, and the plurality of supporting columns are arranged at intervals along the sliding direction of the snow, so that the plurality of guide snow plates 5 and the supporting column 3 are uniformly stressed, thereby making the effect of changing the snow flow direction better and the system operation more stable.

[0063] Embodiment 3

[0064] Reference Figure 2 Compared with embodiments 1 and 2, the difference is that the guide snow plate 5 is a three-wave wave-shaped plate, and is connected with the stabilizing column 2 and the supporting column 3 through fasteners, the first mounting hole 51 is fixedly connected with the mounting hole 24 through a fastener, and the second mounting hole 52 is fixedly connected with the mounting hole 32 through a fastener. The spacing between the guide snow plates is 10cm-15cm, and the bottom edge of the lowermost guide snow plate is 25cm-40cm away from the ground.

[0065] The gap between the guide snow plates can effectively reduce the degree of wind-blowing snow; at the same time, when the avalanche comes, the gap between the guide snow plates can pass part of the snow body, reduce the impact force of the avalanche on the device, and improve the service life of the device. The three-wave guide snow plate 5 has higher strength and better performance of resisting the impact force of the avalanche, which helps to improve the stability of the whole device and has better snow guiding capacity.

[0066] Embodiment 4

[0067] An avalanche protection system comprises a plurality of avalanche protection devices.

[0068] The avalanche protection devices are arranged on the slope in multiple rows, and each row of avalanche protection devices is arranged with multiple avalanche protection devices along the direction of the road, the avalanche protection devices in adjacent two rows are arranged staggeredly, and the number of the avalanche protection devices in each row is decreased successively from top to bottom, so that the multiple avalanche protection devices form an avalanche protection system.

[0069] The multiple wave-shaped plate avalanche protection devices work cooperatively, each avalanche protection device can adopt different placement angles, when the avalanche comes, a single avalanche protection system can not only consume the avalanche energy and change the flowing direction of part of the snow body, but also guide the related impact of the snow body by reasonable arrangement, further consume the avalanche energy, and make the avalanche stop on the slope far away from the road and the railway.
