s5, in severe winter, a user can close a group of chimney fans every other along the width direction to keep the temperature of the animal house, at the moment, an electric push rod (19) does not work, a flow guide cover (11) and a rain shade (12) are completely attached to an air collector (1), an EC motor (24) in the closed chimney fans is opened and controls the direction of the EC motor to rotate, so that the group of chimney fans are subjected to internal circulation, and fresh air preheated by adjacent chimney fans is uniformly fed to the lower part and the periphery of the closed group of chimney fans to ensure the normal breathing of animals;
s6, when the outside air is very suitable for the growth of animals in spring and autumn, a user sets the EC motor (24) of one row of chimney fans in the length direction of the livestock house as an air inlet fan, and sets the EC motor (24) of the other row of chimney fans as an air exhaust fan to enable the air in the livestock house to circulate in the width direction, so that the circulation of fresh air is guaranteed to take away waste gas and waste heat on the surfaces of the animals to cool the interior of the livestock house.
2. The elevating chimney fan with a heat preservation function according to claim 1, wherein: the user can control the flow of the chimney fan by adjusting the rotating speed of the row of chimney fans, so that the animal house is internally set to be micro-positive pressure or micro-negative pressure to meet different requirements of the user.
3. The elevating chimney fan with a heat insulating function according to claim 2, characterized in that: the lifting chimney fan can be combined with a cooling water curtain, an air filter or an air quantity monitoring system and a 485 communication function to be suitable for the operation condition of the real-time monitoring fan of the Internet of things, and full-automatic intelligent control of the Internet of things is achieved.
