Long barrel impeller power unit

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.

Description

technical field [0001] The present invention is a long tube impeller type power device. It involves wind power generators, turbo generators, gas turbines, and three kinds of power devices. Background technique [0002] 1. The power plant of the existing wind turbine: [0003] The power device of the existing wind-driven generator impeller can be described as tall, big, clumsy, heavy, and low-energy. There are two aspects of height, one is that it is very long and tall in size, and the other is that its manufacturing cost is very high and the manufacturing cost is extremely high. Big refers to its large size. Stupid means that it is cumbersome to transport and cumbersome to hoist. Heavy refers to its particularly large body weight. Low energy means that it produces relatively little energy. [0004] Its reason is: (1) the blade of wind-driven generator impeller is very long very little generally only has three. (2) The blade speed of the impeller is extremely slow. (3...

AI Technical Summary

Problems solved by technology

[0004] The reasons are: (1) The blades of the wind turbine impeller are very long, very small, generally only three

(2) The blade speed of the impeller is extremely slow

(3) Although the blade is very long, the utilization rate of its windward surface is small, especially the force on the blade tip is smaller

(4) The number of blades is very small, and the speed is extremely slow so that it cannot produce inertia

(5) Due to its extremely slow speed, it needs to be equipped with a transmission

Large air gap, more air leakage, low efficiency
