After the gas sensor 7 detects that the concentration of harmful gases in the main support 1 of the cowshed exceeds the set threshold value, the electric cylinder 41 extends to drive the connecting arm 42 to rotate, thereby opening the exhaust port 6. At the same time, the exhaust fan 5 works to quickly discharge and replace the gas in the main support 1 of the cowshed through the exhaust port 6 set on the top of the main support 1 of the cowshed. The exhaust fan 5 and the electric cylinder 41 are electrically connected with a relay, and the gas sensor 7 is electrically connected with a single-chip microcomputer, which is electrically connected with the relay. After the gas sensor 7 detects that the concentration of harmful gases in the main support 1 of the cowshed exceeds the set threshold value, under the control of the single-chip microcomputer, the exhaust fan 5 and the electric cylinder 41 When powered on, automatic exhaust replacement is realized. The straight line where the axis of the exhaust fan 5 is located passes vertically through the top of the main bracket 1 of the cowshed. After the electric cylinder 41 is extended to the end of the stroke, the connecting arm 42 is in a V-shaped structure. After the connecting arm 42 is expanded upward under the push of the electric cylinder 41, the exhaust fan 5 works to suck the air below, and the exhausted air is quickly discharged along the bottom surface of the shed cover 43.
