Abstract

The invention discloses a cylindrical impeller type power device and relates to power devices of wind driven generators. The cylindrical impeller type power device is composed of an emergency fan cover mechanism, a cylindrical impeller mechanism, a low-pressure guide air drum and a weather cock support mechanism. The cylindrical impeller type power device is most characterized in that an impeller can directly drive an electric generator to rotate. The electric generator is located in the cylindrical impeller, so that the device is small in size, low in weight, extremely high in specific power and high in cost performance. A large number of blades of the cylindrical impeller are arranged, and the blade surfaces are ultra wide; the low-pressure guide air drum of the device can also utilize the pressure difference of wind force and siphonage, so that the rotating speed of the cylindrical impeller is high, generated inertial energy is very high, and much power is produced. When the rotating speed of the impeller is extremely high, an emergency fan cover will open automatically, and a machine is prevented from being damaged by propeller racing. The device will surely change the situation that an existing draught fan is high, large, clumsy, heavy and low in efficiency. The cylindrical impeller type power device will certainly become a new development trend in the future. Due to the fact that a transmission shaft of a power device of the steam-turbine generator is quite short, the diameter of the impeller is quite large; as a result, the impeller acts according to inertia and the lever principle of a wheel axle, and efficient specific power and extremely low manufacturing cost are realized.
