Building ventilation structure
A mounting hole is formed in the middle of the frame body, a ventilation fan is arranged on the inner side of the shielding fence, a mounting groove communicated with the mounting hole is formed in the front side of the frame body, a plurality of rotating shafts are rotationally assembled in the mounting groove from top to bottom in a whole row, an inner cavity is formed in one side of the frame body, and one end of each rotating shaft extends into the inner cavity to be fixedly connected with a gear; an electric telescopic rod is assembled on the inner wall of the upper side of the inner cavity, one end of the electric telescopic rod is fixedly connected with the upper end of the rack, sliding grooves are formed in the inner walls of the multiple sleeves, and supporting pieces stretching into the sliding grooves are fixedly connected to the outer surfaces of the multiple rotating shafts. And external foreign matters can be prevented from entering the interior of the building, when a worker forgets to open the baffles and starts the ventilation fan, the baffles can be unfolded through wind power, and finally dust accumulated in the mounting holes can be cleaned through rainwater.
本发明包括框体，框体中部设有安装孔，遮挡栏内侧设有通风电扇，框体前侧设有与安装孔连通的安装槽，安装槽内由上至下整列转动装配有若干转轴，框体一侧设有内腔，若干转轴一端均伸入内腔固定连接有齿轮，内腔上侧内壁装配有电动伸缩杆，电动伸缩杆一端与齿条上端固定连接，若干套筒内壁均设有滑动槽，若干转轴外表面均固定连接有有伸入滑动槽的支撑件，本发明可在工作人员需要时通过若干挡板将安装孔封闭，可防止外界异物进入建筑内部，还可以在工作人员忘记打开挡板而启动了通风电扇时，利用风力便可将若干挡板展开，最后还能利用雨水对安装孔内部堆积的灰尘进行清理。
