“体育生白袜自慰出精🔞🈲网站”青海西宁电体育生白袜自慰出精🔞🈲网站网建设工作由地面运输转向空中运输

  中新体育生白袜自慰出精🔞🈲网站网西宁11月29日电 体育生白袜自慰出精🔞🈲网站(沈仪 喇小青 李江宁)29日,国网西宁供电公司工作人员正使用无人机将塔材运送至半山腰的35千伏前营变电站增容扩建工程42号铁塔建设现场。这是该公司首次试点将载重无人机应用于电网建设物资运输领域,标志着西宁电网建设工作由地面运输转向空中运输。

  35千伏前营变电站增容扩建工程位于青海省西宁市湟中区,是确保湟中区共和镇双电源供电、助力“煤改电工程”落实落地的一项重点民生项目,需建设77基杆塔,而这些杆塔预设位置大多位于山区,地形复杂,地势起伏且海拔差异显著,给线路施工材料运输带来了极大的困难。

  据悉,如果采用传统的人力畜力运输,不仅存在运距长、运量小、耗时长、作业环境差等问题,而且在遇到结冰等恶劣路况时,安全风险显著增加。应用载重无人机,不仅有效提升了电网建设物资运输效率,也降低了作业人员的安全风险。

  随着操作员推动无人机操作遥感,四旋翼无人机在轰鸣声中升空。工作人员迅速将完成打捆并放置于地面的50公斤塔材挂放于长绳吊索末端挂钩处,塔材便随着无人机飞往指定区域。

  “保持稳定,注意风向。”此项作业负责人林枭叮嘱无人机操作员。两分钟后,首批50公斤的塔材精准到达预定位置,目的地工作人员取下材料后,无人机快速返回山脚,圆满完成了首次运输任务。

  “这种四旋翼重载无人机,能有效满足短距离、高落差、多频次作业需求,每天可开展飞行200架次。”林枭介绍说,本次试点运输飞行高度150米,直线距离1800米,载重无人机总共吊运70余趟,耗时约5小时,完成了500公斤的塔材运输,运输过程快速、稳定、安全。(完)
