我想发明一种可以把旗帜自动收入旗杆内的新型旗杆。这种旗杆的外形与其他旗杆没什么两样,可你仔细往下一看,就会发现旗杆上有一个小门,自动收旗旗杆的妙处就在于此。下雨时,雨点打在旗杆上,旗杆上的感应器即将信号传送给控制器,控制器启动马达,将旗帜降下并送入旗杆上的小门内。天晴了,控制器再次接收到信号,于是旗杆的小门打开,旗帜重新悬挂起来。这样,下雨时,护旗手再也不用冒着雨,手忙脚乱地收旗了。
I would like to invent a new type of flagpole that can automatically raise the flag into the flagpole. This flagpole shape and other flagpoles are no different, but you look down carefully, you will find a flagpole on the door, automatic flag flagpole is where the beauty lies. When it rains, the raindrops hit the flagpole, and the sensor on the flagpole sends a signal to the controller that the controller starts the motor to lower the flag and feed it into the gate on the flagpole. Fine weather, the controller received the signal again, so the flagpole wicket open, the flag resumed. In this way, when it rains, the bearer no longer rains, confused to close the banner.
