    无人机的用途很多,多达N个。就不一一赘述了。总之,无人机提供了一个新的视角,让大家可以俯视我们周围的环境、建筑、风景和生活。今天咱们展示一下它的第N+1个用途。
    九月底十月初,包括温哥华和维多利亚等地的加拿大西部沿海地区,就要陆续进入雨季。雨季一直要延续到来年的四月份。正常年份,这一时段的平均降雨量有1000毫米+,也就是1米多。
    加拿大民居屋顶的平均面积约200平米,用降雨量乘以屋顶面积,就得出了一个雨季屋顶接雨水的体积:200多立方米,折合200多吨。这么多雨水如果任其从房顶上自由流下,时间久了,房子的外墙和地基都会出现问题。
    所以每个房子都有一套雨水接收和排放装置。其中包括:接水槽(gutter)和竖管(downspout)。雨水先流入装在房檐上接水槽,然后再通过竖管进入市政的雨水排放系统。
    经常发生的问题是:接水槽和竖管的连接处,容易被落叶、青苔,甚至鸟窝,给堵住,造成雨水下泄不畅,溢出。所以在雨季来临前,需要登梯爬高上房检查。腿脚利落,不怕高的,这活您自己干;否则就得找人。
    如果您腿脚不灵,晕高,自己还三高,又不想花钱,您不妨试试无人机。下面就来展示一下用无人机检查屋顶接水槽。
