Description

Technical Field

[0001] This utility model relates to the field of wind power generation, and in particular to a wind guide device for wind power generation. Background Technology

[0002] Most existing wind power generation devices adopt a horizontal axis layout, with the core being a wind turbine structure installed vertically, which rotates under the drive of wind power to drive a generator to generate electricity. Although this technology is relatively mature, it still faces several technical bottlenecks in terms of wind energy capture efficiency, equipment adaptability, and operational continuity.

[0003] Traditional structures, characterized by tall towers and large blades, often rely on strong winds for effective operation, limiting their application in locations with complex terrain, low wind speeds, or significant wind fluctuations. Furthermore, when wind direction changes frequently, these systems struggle to respond adequately due to adjustment lag, impacting overall power generation efficiency. Simultaneously, the large mechanical components in the wind turbine and rotation system are prone to accelerated wear, reduced transmission efficiency, and component fatigue during prolonged operation, leading to a heavier operational and maintenance burden.

[0004] Against this backdrop, the wind power sector urgently needs a new type of wind power generation technology that maintains high energy conversion efficiency under complex wind conditions, has a lighter and more flexible structure, and significantly improved response and regulation capabilities, in order to achieve more efficient and reliable wind energy utilization. Utility Model Content

[0005] The purpose of this invention is to provide a wind guide device for wind power generation. As a novel wind power generation structure, this wind guide device can improve the efficiency of wind power generation and increase the utilization rate of natural wind power.

[0006] This utility model is achieved through the following technical solution:

[0007] A wind guide device for wind power generation includes a wind guide frame, which has a cylindrical outline. The wind guide frame includes a circular top plate and a bottom plate, and multiple partitions extending from the outside to the inside are arranged in a ring array along the periphery of the wind guide frame. The top and bottom of the partitions are connected to the top plate and the bottom plate, respectively. A wind guide zone is formed between any two adjacent partitions, and a wind guide hopper is installed on the inner side of each wind guide zone.

[0008] The air guide hopper has a funnel structure; an axially rotating turbine unit is installed in the middle of the air guide frame, and multiple connecting rods are installed in a circular array on the rotating shaft inside the turbine unit, with air-bearing hoppers installed at the ends of the connecting rods.

[0009] The air outlets of the funnel pipes inside the air guide hopper all face the air receiving hopper; the turbine unit is electrically connected to the power distribution room.

[0010] Compared with previous technologies, the beneficial effects of this utility model are as follows:

[0011] 1. By optimizing the wind energy diversion path, the wind energy utilization rate per unit area is improved, and a high power generation output efficiency can still be maintained, especially in the case of wind change.

[0012] 2. Compared with traditional high-tower large wind turbine devices, this utility model has a more flexible layout and can operate well in low-to-medium wind speed areas, complex terrain, or environments with limited construction conditions.

[0013] 3. This utility model supports flexible deployment and functional expansion in different scales and scenarios, providing a broader technical path for the application of wind power in urban buildings, remote areas and distributed energy systems. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description:

[0021] like Figures 1 to 4 As shown, a wind guide device for wind power generation includes a wind guide frame 1. The wind guide frame 1 has a cylindrical outline and includes a circular top plate and a bottom plate. Multiple partitions 12 extending from the outside to the inside are arranged in a ring array along the periphery of the wind guide frame 1. The top and bottom of the partitions 12 are connected to the top plate and the bottom plate, respectively. A wind guide zone is formed between any two adjacent partitions 12. A wind guide hopper 11 is installed on the inner side of each wind guide zone.

[0022] The air guide hopper 11 has a funnel structure; an axially rotating turbine unit 13 is installed in the middle of the air guide frame 1, and multiple connecting rods 131 are installed in a ring array on the rotating shaft inside the turbine unit 13, and an air-receiving hopper 132 is installed at the end of each connecting rod 131.

[0023] The air outlets of the funnel pipes 111 inside the air guide hopper 11 all face the air receiving hopper 132; the turbine unit 13 is electrically connected to the power distribution room.

[0024] It should be noted that in this invention, natural wind flows into the wind guide hopper, is blown out through the converging capacity of the funnel pipe, and drives the wind-receiving hopper to rotate, thereby driving the connecting rod and the turbine unit to rotate, thus generating electricity. In this process, the funnel pipe 111 with a gradually narrowing diameter can accelerate the wind speed of the natural wind to improve the utilization rate of wind power. The funnel pipe 111 has an arc structure, and the direction of the wind blown out from the outlet of the funnel pipe is approximately tangent to the rotation trajectory of the wind-receiving hopper 132.

[0025] Furthermore, the air guide frame 1 is provided with an annular guide plate 14, which is located around the turbine unit 13.

[0026] The funnel tube 111 of the air guide hopper 11 passes through the annular guide plate 14. This design allows the air to circulate along the annular guide plate 14, improving the utilization rate of natural wind.

[0027] Furthermore, such as Figure 3 As shown, the air guide hopper 11 can also be configured as a square funnel structure.

[0028] Example 2:

[0029] The air guide hopper 11 has six to eight sections, including at least one set of air guide groups; each air guide group consists of two adjacent air guide hoppers 11; wherein the outlets of the funnel pipes 111 of the two air guide hoppers 11 in this set converge to form a common outlet. Under this structural design, the number of air guide hoppers must be even, such as... Figure 5 The diagram shows a design with six partitions and six air guide ducts 11. The air guide ducts 11 are grouped in pairs to form three air guide groups. This illustration is for reference only. The design of the air guide groups combines the funnel tubes 111, which can gather air from more directions to the same main air outlet, achieving better air gathering ability and further increasing the wind speed.

[0030] In summary, compared to traditional high-tower, large-scale wind turbine devices, this invention offers more flexible deployment options and can operate effectively in low-to-medium wind speed areas, complex terrain, or environments with limited construction conditions. By optimizing the wind energy flow path, it improves the wind energy utilization rate per unit area, maintaining high power generation efficiency, especially under varying wind conditions. It supports flexible deployment and functional expansion in different scales and scenarios, providing a broader technical path for the application of wind power in urban buildings, remote areas, and distributed energy systems.

[0031] Although this utility model has been illustrated and described using specific embodiments and alternative methods, it should be understood that various changes and modifications are permitted as long as they do not depart from the spirit and scope of this utility model. Therefore, it should be understood that this utility model is not limited in any sense except by the appended claims and their equivalents.
