The invention relates to a stability control device for making draught fan air deflection blades automatically open and close. The stability control device is characterized by comprising a linkage rod arranged on a draught fan shell, several swing arms and a positioning mechanism, and the linkage rod is the connecting rod located at the sides of rotary shafts of all the air deflection blades; each swing arm is a swing part of which one end is fixedly connected to the rotary shaft of the corresponding air deflection blade, and the other end is rotatably installed on the linkage rod, and the swing parts control all the air deflection blades to be rotatably opened / closed synchronously back and forth under the effect of the linkage rod; the positioning mechanism is used for controlling the air deflection blades to be automatically in a stable opened / closed state when a draught fan is opened / closed. The stability control device for making the draught fan air deflection blades automatically opened and closed has the advantages of being simple in structure and convenient to install, and having the functions of controlling the air deflection blades to be opened or closed without using the electricity, and being high in usability, and capable of saving electricity.
Description
technical field [0001] The present invention relates to a control component of a fan, in particular to a control device for controlling the opening or closing state of the wind guiding blades. Background technique [0002] At present, the opening and closing of the exhaust fan is controlled by the motor gear, and the centrifugal mechanism (including the centrifugal hammer or the centrifugal arm, etc.) is also used as the power to open or close the louvers. External strong wind greenhouse louver fan" invention patent and patent No. 201220169377.6 "a kind of exhaust fan with louver" invention, in these two methods, the motor gear control method needs to be connected to the power supply, which is costly; the centrifugal mechanism method is used, although Electric control is not required, but the structure is complicated, the work stability is poor, and the production cost is high. Contents of the invention [0003] In order to solve the deficiency of automatic opening or clo...
