The snow-proof net 1 comprises a frame 8, and a net piece 9 is arranged on the frame 8. The net sheet 9 is made of a metal plastic coated net which has the advantages of strong durability, high strength, low cost and the like. The porosity of the net sheet 9 can be determined according to local wind and snow flow characteristics, and a metal plastic-coated net with low porosity (30-60%) can also be selected. The height of the snow blocking net can be designed to be 40cm-80cm, and can also be adjusted according to the local wind and snow flow condition. The frame 8 is used for further improving the stability of the snow-blocking net 1 and preventing the net sheet from being damaged when wind blows snow to pass through.

As shown in fig. 4, the spoiler 3 in the snow-barrier apparatus of the present invention comprises a vertically disposed rotating shaft 10, a rotor 11 which is sleeved on the rotating shaft 10 and can rotate back and forth around the axis of the rotating shaft 10, wherein the rotor 11 comprises a cylindrical connecting sleeve which is rotatably connected with the rotating shaft 10, the connecting sleeve can rotate back and forth along the outer surface of the rotating shaft 10, and at least two wind-driven plates are uniformly distributed on the outer wall of the connecting sleeve; the upper end of the rotating shaft 10 is fixedly connected with the top plate 6, and the lower end of the rotating shaft 10 is fixedly connected with the bottom plate 7.

The rotor 11 may also be: the wind power generator comprises a vertically arranged rotating shaft 10, wherein a connecting sleeve is sleeved on the rotating shaft 10, and at least two wind moving plates are uniformly distributed on the outer wall of the connecting sleeve; at this time, the upper end of the rotating shaft 10 is rotatably connected to the top plate 6, and the lower end of the rotating shaft 10 is rotatably connected to the bottom plate 7.

When the snow barrier device of the invention is used: the snow-blocking wall device is arranged at a designated position, so that the spoiler 3 is positioned at the windward side of the main wind direction, and the snow-blocking net 1 is positioned at the leeward side of the main wind direction. When the wind with the snow particles is blown through the snow retaining wall device, the wind firstly blows the spoiler 3, the rotor wing 11 rotates under the action of wind power, so that the wind and snow flow structure of the main wind direction is changed, wind energy is lost, vortex flow is formed in front of and behind the spoiler 3, the wind speed of the wind and snow flow is rapidly reduced, the energy of the snow particles driven by the wind flow is weakened, and a large amount of snow particles are deposited near the snow retaining wall device to form accumulated snow. After a small part of snow particles passing through the spoiler 3 along with wind reach the snow blocking net 1, the snow blocking net 1 further enables wind blown snow to be deposited inside the snow retaining wall device, and eddy currents are formed in the front and the back of the snow blocking net 1, so that the wind and snow flow structure is changed again, the snow blocking effect is achieved, and snow is deposited. The inside snow of deposit at the snow-retaining wall device passes through the heating of electric heating plate 5, and the snow melts fast, prevents because of snow is too much, reduces the snow-proof effect of snow-retaining wall device.

In practical use, the height of the spoiler 3 can be selected according to the characteristics of the snowing wind and the project to be protected, and the spoiler 3 with the height of 3m can be selected generally. When the snow flows pass through the spoiler 3, the rotor wings 11 on the spoiler 3 can rotate, so that the snow flow structure is changed, a vortex is formed, the effects of energy dissipation and speed reduction are achieved, and snow particles are deposited near the snow retaining wall. Certain gaps are formed among the spoilers 3, so that when wind blows snow to pass through the spoilers 3, the local wind speed can be improved, the rotating speed of the spoilers 3 is accelerated, the wind and snow flow structure can be better changed, and the snow blocking efficiency is improved.
