Abstract
Description
Technical Field
[0001] This application relates to the energy field, and more particularly to a vertical bladeless micro-wind turbine generator set. Background Technology
[0002] In areas with less than ideal wind resources, wind speeds remain below 4 m / s for most of the day. Although the wind speed is low, this energy persists for a considerable period and accumulates over time. With ordinary wind turbines, most of this energy would be wasted. Furthermore, most wind turbines on the market currently have exposed blades that rotate at high speeds, which also causes noise and safety issues. Summary of the Invention
[0003] To address the above issues, this invention provides a bladeless wind turbine generator applicable to low-wind environments. This invention utilizes a wind harvesting tower to collect wind energy from all directions. The wind energy is accelerated and concentrated by a venturi tube before being transmitted to a turbine below, which in turn drives a generator to produce electricity.
[0004] To achieve the above objectives, the generator set structure of the present invention is as follows: Figure 1 As shown, it includes a wind collection tower (1), which is mainly composed of a guide fin (2) and a guide plate (3). The wind collection tower (1) is installed above a venturi tube (4). A turbine (5) and a generator (6) are connected below the venturi tube (4). There are flange holes on the outer edge of the venturi tube (4) for connecting the outer casing support (7) and the wind collection tower (1).
[0005] The working principle of this invention is: The wind blows into the wind collection tower (1) and changes its direction downwards after passing through the guide plate (3). The guide fin (2) can improve the radial overflow of the wind and improve the efficiency of the collection tower. After passing through the wind collection tower (1), the wind flows vertically downwards into the venturi tube (4). The diameter of the venturi tube (4) gradually narrows from top to bottom, which increases the wind speed and concentrates the wind energy. The accelerated airflow drives the turbine (5) to rotate, and the turbine (5) drives the generator (6) to generate electricity.
[0006] The beneficial effects of this invention are as follows: 1. The presence of the Venturi tube accelerates the airflow, creating negative pressure in the area behind the wind collector where there is no direct wind flow. This negative pressure draws in air, thus collecting wind energy. Figure 2 As shown, the accelerated airflow acts on the turbine, significantly increasing its speed, which is more conducive to generator operation. 2. Because all rotating parts are internally mounted, it is safer and quieter, and will not harm birds or disturb nearby residents.

[0007] To better understand the present invention, the invention will be further described below with reference to the accompanying drawings and embodiments, but the implementation of the present invention is not limited thereto.
[0008] like Figure 1 As shown, the wind collection tower (1) is mainly composed of guide fins (2) and guide plates (3). The guide fins (2) and guide plates (3) are made of resin. The guide plates (3) are fixed to the guide fins (2) with bolts, and the guide fins (2) are fixed to the wind collection tower (1) with bolts. There is a flange at the bottom of the wind collection tower (1), which is used to connect the venturi tube and the outer casing support (7). The venturi tube is made of resin and has internal partitions, which can prevent airflow from entering from different directions from interfering with each other. There is also a flange at the bottom of the venturi tube, which can be used to fix the turbine and generator with bolts. The outer casing support (7) is welded from steel and powder coated, which plays a role in protecting the equipment and supporting the generator set.
