Air-operated machine

Abstract

The invention discloses an air-operated machine, and relates to the field of industrial machinery. The air-operated machine comprises a fan shaft and blades. The fan shaft is a long and straight cylindrical rod and is provided with a disc type driver, the disc type driver is connected with a supporting frame composed of three fan blades arranged at equal intervals, the clockwise circumference offset angle between every two adjacent fan blades is 28-32 degrees, and the three fan blades of the supporting frame are sequentially and perpendicularly connected with the blades. The blades are bent long plates with the wing-typed sections, and the circumference angle between every two adjacent blades is 119-121 degrees. An output shaft is arranged at the lower end of the fan shaft. The disc type driver can provide driving force for self-starting of the blades. Due to the wing type design and perpendicular connection of the blades, air resistance in the rotation process can be reduced, the lift force can be increased, the maximum linear speed output is guaranteed, and high output power can be provided. In addition, the structure is simple, and the reliability is high.

Description

technical field [0001] The invention belongs to the field of industrial machinery, in particular to a wind turbine. [0002] Background technique [0003] As a kind of clean renewable energy, wind energy is more and more paid attention to by countries all over the world, and the application of wind power generation is also more and more extensive.

[0003] As a kind of clean renewable energy, wind energy is more and more paid attention to by countries all over the world, and the application of wind power generation is also more and more extensive. Among them, there are many studies on wind motors. For example, application number 00119168.3 discloses a wind motor, Including gearbox, wind blade, power output shaft, orientation shaft, adjustment plate and bevel gear, there are two large bevel gears, two small gears, one fixed bevel gear and one movable bevel gear respectively in the gear box , wherein the large bevel gear and the small bevel gear are respectively connected to the fan blades, the fixed bevel gear is connected to the directional shaft, and the moving bevel gear is connected to the power output shaft. The installed adjusting plate can immediately adjust the direction of the wind turbine according to the change of the wind direction, which has achieved the purpose of high efficiency. However, the force bearing area of ​​the fan blade of this invention is small, and the generated moment is small. At the same time, the adjustable range of the wind direction adjusting plate is small. The requirements for wind direction are relatively high.
