The utility model relates to a non - equal thick double support plate wheel hub for axial flow fan, the utility model discloses the structure of upper support plate and lower support plate cooperate upper and lower clamp is used to fix fan blade, forms the mounting structure of closure, and the annular package of blade pulp root is carried out, improves the reliability of installation, and the upper support plate of relatively thick guarantees the strength of overall structure, and the lower support plate is used as the auxiliary support to blade, can effectively promote overall rigidity, through reducing the thickness of lower support plate and opening the hole in the center, can effectively reduce the weight of overall structure while guaranteeing the structural strength. The upper and lower clamp structure cooperation two sides set up the double -end fastening bolt and carry out the clamping fixation fan blade, guarantee structural connection stable, improve the operation safety of fan. And through the stop washer and be connected fixed between the double -end fastening bolt, and through setting the notch on the stop washer, through bending can make it be covered on the nut, play the effect of anti - loosening, guarantee the connection stability of double -end fastening bolt.

The invention discloses a visual interactive winch cage state early warning system. The early warning system comprises a winch equipment operation unit and a cage state early warning unit. The hoisting equipment operation unit comprises a hard disk video recorder, a cage hoisting console, a video call phone, a first ad hoc network base station and a wireless charging module A; the cage state early warning unit comprises an STM32-based cage controller, a second ad hoc network base station, a wireless charging module B, a lithium battery, a camera A and a direct-current illuminating lamp. According to the visual interactive winch cage state early warning system, the wireless charging module is arranged to charge the lithium battery, the problems that a winch cage runs in a shaft at a high speed, and the interior of the winch cage cannot be connected with a fixed power source are solved, the winch equipment operation unit and the cage state early warning unit are combined, and the safety of the winch cage is improved. Information interaction of communication between the master control operation platform of the well mouth winch cage and the interior of the cage is provided, and the operation safety coefficient of the cage is improved.
