Abstract

The invention discloses a novel coaxial counter-revolving double-blade fan comprising a box body. The box body is fixedly connected with a base through a support. An inner blade and an outer blade are arranged outside the box body and counter revolves around a rotary main shaft. One end of the rotary main shaft is fixedly connected with the outer blade, and the other end of the rotary main shaft extends to the inner side of the box body. The rotary main shaft is connected with a motor providing power for revolution of the inner blade and the outer blade through a coupler. The motor and the rotary main shaft drive the revolution of the inner blade and the outer blade through transmission of a gear set. The novel coaxial counter-revolving double-blade fan is in double-blade coaxial counter revolution, counteracts an additional torque produced in the revolution process of one single blade, and thereby reduces rigidity requirements for the support and the base. Additionally, due to the fact that the two blades are used, on the condition that identical electric energy is used, produced wind power is twice that of a common single blade, and the utilization rate of the electric energy is improved.
