Rotary wind gathering and guiding device and horizontal vertical axis wind generator

Abstract

The invention relates to a rotary wind gathering and guiding device and a horizontal vertical axis wind generator. The rotary wind gathering and guiding type horizontal vertical axis wind generator comprises a machine cabin, the wind gathering and guiding device, drive steering devices, wind wheels, a wheel swinging prevention device, an annular stable supporting device and a supporting rotary table device. A second cylindrical structure is located on the rear portion of a first cylindrical structure of the rotary wind gathering and guiding device and has the same axis with the first cylindrical structure. A transmission shaft is arranged at the axis position, and the diameter of the second cylindrical structure is smaller than that of the first cylindrical structure. The machine cabin isarranged at the center position of the first cylindrical structure. The outer surfaces of the two sides of an outer cylinder of the first cylindrical structure are each provided with one drive steering device. The front end of an inner cylinder of the first cylindrical structure is provided with a wind guiding conical cylinder. The rear portion of the second cylindrical structure is provided withthe wheel swinging prevention device. The outer end of the first cylindrical structure, the outer end of the second cylindrical structure, the outer end of the wheel swinging prevention device and theouter end of the wind guiding conical cylinder are sleeved with an annular structure on the annular stable supporting device. The lower end of the annular structure is further provided with a plurality of inwards-inclined supporting columns. The bottom of the first cylindrical structure is provided with the supporting rotary table device. By means of the rotary wind gathering and guiding device and the horizontal vertical axis wind generator, the utilization rate of the wind energy can be remarkably increased.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, in particular to a rotatable wind gathering and guiding device and a horizontal vertical axis wind power generator. Background technique [0002] At present, large-scale wind power generation equipment is divided into two types: one is the horizontal axis wind power generator; the other is the vertical axis wind power generator. The generator, which acts on three symmetrical paddle blades through wind force, makes the blades rotate to form torque, which is transmitted to the generator set in the cabin to generate electricity through the axle, but it still has many shortcomings. The details are as follows: [0003] 1. When the wind direction changes suddenly, because the blade is very long, the sudden acceleration of the turning will damage the blade or the horizontal shaft and bearing. [0004] 2. Because of the three paddle-type blades, the wind-receiving area is very small, and m...

Problems solved by technology

[0003] 1. When the wind direction changes suddenly, because the blade is very long, the sudden acceleration of the turning will damage the blade or the horizontal shaft and bearing.

[0004] 2. Because of the three paddle-type blades, the wind-receiving area is very small, and most of the wind energy flows through the blades and is lost in vain. Even if the wind touches the blades, because it is a paddle-type blade, it has a Because of the angle problem, part of the wind energy is lost, and considering the strength and reliability of the blade, the widest part of the blade surface is set at a position close to the shaft, so the moment is much smaller. In summary, these problems The wind energy obtained by the generator is reduced exponentially.

[0005] 3. Since the chassis and impeller blades of the three-bladed paddle wind turbine are all installed on the top of the iron tower with a height of tens of meters or nearly a hundred meters, it is difficult to install; Generators and all the internal components of the engine room are required to achieve high reliability and precision in the process of manufacturing, which greatly increases its manufacturing cost.

[0006] Due to the large investment and low yield of three-blade wind turbines, for now, three-blade wind turbines can only be used as a supplement to power generation equipment.
