Embodiment Construction

[0013] In order to make the purpose, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0014] Such as figure 2 As shown, the near-earth wind power generation device is mainly composed of the following parts: wind collecting box (1), inclined top cover (2), curvilinear reducer air inlet (3), air inlet (4), spiral air duct (5 ), air outlet (6), reinforcement ring (7), tower tube (8), fan blades (9), wind guide cover (10), generator (11), motor base (12), annular air outlet (13).

[0015] The working process of the device is as follows: the air collection box (1) has four curvilinear reducing tube air inlets (3) to gather the incoming wind from all directions into the spiral air duct (5) so that the wind speed can be greatly increased, and the accelerated air flow passes through the spiral air duct (5). Guided by the air duct (5), it blows...

Abstract

The invention provides a ground-proximity wind power generation device. Wind in each direction is collected through wind collecting ports of curved reducing pipes at four sides of a wind collecting box, and the wind speed is improved greatly so that a wind turbine is driven to rotate, and low-speed wind energy can be effectively utilized for power generation. The device can meet the requirement for power generation using ground-proximity low-speed wind energy in vast urban areas, and the power supply shortage in central areas with low wind speed load is solved effectively. In addition, the ground-proximity wind power generation device has the advantages of small work amount of construction, and easy construction, and is also applied and popularized in remote areas as a distributed power generation device.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a near-earth wind power generation device. Background technique [0002] Wind energy is an important renewable resource. At present, my country's large-scale wind energy development and utilization areas are concentrated in high wind speed areas rich in wind energy resources, mainly including north-central Inner Mongolia, southeast coastal areas and parts of Xinjiang. The area is relatively small and far away from the load center. A large part of my country has wind all the year round, but the wind speed is low. The regions with abundant low-speed wind energy resources are widely distributed in my country. The utilization of such low-speed wind energy is of great significance to the development of wind power generation. [0003] At present, conventional wind turbines have low utilization efficiency for low-speed wind energy, and are not suitable for installation in large area...
