[0019] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] Reference Figure 1 , Figure 2A monitoring facility for preventing and controlling wind and sand disasters on railways comprises a support frame 1, on which a collection pipe 2 is vertically rotatably connected, a plurality of sand collecting tubes 3 are connected to the side walls of the collection pipe 2, and the plurality of sand collecting tubes 3 are arranged at equal intervals along the height direction of the collection pipe 2 to collect wind and sand at different height positions.

[0021] Reference Figure 1 , Figure 2 A plurality of air outlets 4 are provided on the collection pipe 2, and the plurality of air outlets 4 are aligned one by one with the plurality of sand collecting tubes 3, and a sand filter net 5 is provided in each air outlet 4, so that when the wind and sand enter the collection pipe 2, the wind can quickly penetrate through the sand filter net 5, and the sand and gravel are filtered by the filter net.

[0022] Reference Figure 1 , Figure 2 The top of the collection tube 2 is fixedly connected with a wind vane 6, and the open end of the sand collecting tube 3 faces the indicating arrow of the wind vane 6, that is, the opening direction of the sand collecting tube 3 is controlled by the wind vane 6, so that the open end of the sand collecting tube 3 faces the direction of the wind source, thereby improving the wind sand collection effect. At the same time, a collection bag 7 is arranged on the support frame 1, and the bottom end of the collection tube 2 is connected to the collection bag 7 to realize the collection of sand and gravel.

[0023] By setting up multiple sand collecting tubes 3 arranged in the vertical direction, multiple sand collecting tubes 3 can collect wind-blown sand at different heights at the same time, providing favorable data guarantee for subsequent sand content prediction, improving the accuracy of sand content prediction, so that staff can adopt disaster prevention and control facilities in time and reduce the occurrence of safety accidents.

[0024] Reference Figure 1 , Figure 2 The collecting bag 7 includes a cylindrical bag body 71, a support ring 72 is fixedly connected to the top port of the bag body 71, and the bottom port is tightened by a tightening belt 73.
