Sand prevention grid for desert road section rail
The invention discloses a sand prevention grid for a desert road section rail. The sand prevention grid comprises two pre-embedded piles, a sliding groove is formed in the side wall of each pre-embedded pile, iron blocks are slidably connected into the sliding grooves, the opposite side walls of the two iron blocks are jointly and fixedly connected to a sand prevention net, electromagnets are fixedly connected to the inner tops of the sliding grooves, strip-shaped grooves are formed in the upper ends of the pre-embedded piles, and power supply devices for supplying power to the electromagnetsare installed in the strip-shaped grooves. According to the invention, when no sand wind exists or the sand wind is small, the sand prevention net falls onto the ground and is covered by sand, and when the sand wind is heavy, the electromagnets can generate large magnetic force and attract the iron blocks to move upwards, the sand prevention net is pulled up to block the sand wind, therefore the sand wind can be prevented from invading the rail, the solarization time of the sand prevention net is greatly shortened, and the sand prevention net is prevented from seasoning cracking and falling off due to long-time strong light solarization.
本发明公开了一种用于沙漠路段铁轨的防沙网格，包括两个预埋桩，每个所述预埋桩的侧壁均开设有滑槽，所述滑槽内滑动连接有铁块，两个所述铁块的相对侧壁共同固定连接有防沙网，所述滑槽的内顶部固定连接有电磁铁，所述预埋桩的上端开设有条形槽，所述条形槽内安装有向电磁铁供电的供电装置。本发明通过在无风沙或风沙较小时，使防沙网落在地面上并被沙土掩盖，在风沙较大时，可使电磁铁产生较大磁力并吸引铁块上移，将防沙网拉起进行阻拦风沙，如此既能够防止风沙侵袭铁轨，同时还大大减少防沙网的曝晒时间，以避免防沙网长时间在强光曝晒下而干裂脱落。
