[0030] Working principle: When in use, firstly, a plurality of holes A102 are opened on the outer wall of the duct 101, and the connecting shafts A103 movably inserted on the inner walls of the plurality of fan blades 104 are fixedly inserted on the inner walls of the plurality of holes A102, so that the plurality of fan blades 104 can perform fan-shaped movements around the connecting shafts A103, thereby achieving control of the air volume inside the duct 101, and at the same time, holes B105 are opened through the outer walls of the plurality of fan blades 104, and the inner walls of the plurality of holes B105 are fixedly inserted with connecting shafts B106, and the outer walls of the plurality of connecting shafts B106 are movably sleeved with connecting shafts The outer wall side of the plurality of electric telescopic rods 108 is fixedly connected to the outer wall side of the plurality of connecting frames A107, and then the plurality of connecting shafts C110 are movably inserted into the inside of the holes C109 opened on the outer wall side of the plurality of electric telescopic rods 108. At the same time, the outer walls of the plurality of connecting shafts C110 are fixedly sleeved with connecting frames B111, and the plurality of connecting frames B111 are fixedly connected to the outer wall side of the fixing block 112 by using the plurality of connecting frames B111. At the same time, the fixing rod 114 fixedly connected to the inner wall of the pipeline 101 is fixedly inserted into the inside of the hole D113 opened on the top of the plurality of fixing blocks 112, so that the electric telescopic rods 108 can be fixedly connected to the outer wall side of the pipeline 101. One end of the electric telescopic rod 108 remains in a fixed state while the fan blades 104 can be automatically pushed to open and close. When the exhaust volume of a certain room needs to be adjusted, the multiple electric telescopic rods 108 are controlled to be extended and retracted. If the air volume is too large, the electric telescopic rods 108 are controlled to be extended to make the multiple fan blades 104 infinitely close to a vertical state, thereby hindering the air flow and reducing the air volume. On the contrary, if the air volume needs to be increased, the electric telescopic rod 108 only needs to be controlled to be retracted to make the multiple fan blades 104 close to a horizontal state, so that the air can circulate smoothly and the exhaust volume is increased. At the same time, the two sets of metal fixing columns 202 are The bottom is fixedly connected to a fixed plate 204, and the tops of the two fixed plates 204 are fixedly connected with six dampers 205, wherein the outer walls of the twelve dampers 205 are movably sleeved with shock-absorbing springs 206, and the tops of the twelve dampers 205 are fixedly connected to the bottoms of the two shock-absorbing plates 203, and the bottom of the pipeline 101 is fixedly connected to the tops of the two shock-absorbing plates 203. In this way, the vibration intensity of the pipeline 101 itself is reduced to a certain extent, thereby reducing the intensity of the noise, reducing the damage to the structure of the pipeline 101 caused by vibration, and improving the service life of the entire structure.
