Description

Solar integrated induced wind power generation device

technical field

The invention relates to a power generating device combining solar energy and wind energy, in particular to a solar integrated induced wind power generation system.

Background technique

At present, the most advanced wind power generation technology is to build large-scale wind farms and integrate wind power into conventional power grids for operation. However, there is a bottleneck in this wind power development technology, which is mainly manifested in: the energy density of wind energy is low, and the diameter of the wind rotor is large; the wind direction and wind speed are unstable, so the working time of the generator is limited; under the existing technical conditions, the blade length , the height of the tower, and the range of wind speed are all limited, the power generation is not high, and the utilization rate of wind energy is not high.

Contents of the invention

The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, and to provide a solar integrated induced wind power generation system, which can not only improve the power generation efficiency, but also effectively reduce the cost of the generator system, and obtain a relatively high stable energy density. wind energy.

In order to achieve the above object, the technical solution adopted by the present invention is: comprising a base and a tower body arranged on the base, a trumpet-shaped hollow body is arranged in the tower body, and the cross-sectional area of the air inlet at the lower end of the hollow body is larger than that of the air outlet at the upper end. The cross-sectional area, and a wind wheel connected to the control room and the motor room is arranged at the air outlet, and the surface of the upper end of the tower body is an arc-shaped surface.

The base of the present invention is a solid support cylinder of the tower body, and the tower body is a hollow cylindrical structure; the control room and the motor room are arranged on the solid part of the tower body;

In the present invention, the middle part of the tower body is set into a trumpet-shaped structure, and the cross-sectional area of the air inlet is larger than that of the air outlet. When strong sunlight irradiates the ground, the hot air heated by the solar energy on the ground expands and rises, forming an upward air flow at the air inlet. During the rising process of hot air, according to the second law of thermodynamics and fluid dynamics, the rising speed will become faster and faster, so that the wind energy density at the air outlet is much higher than that at the air inlet, which is enough to drive the wind turbine generator generate electricity. In addition, the present invention designs the top of the tower as an arc-shaped curved surface. The high-altitude airflow flows through the top of the tower and will flow along the top of the tower to form a wind flow rising along the top of the tower. It will play a role in pulling out the rising hot air in the tower, greatly Improve the utilization rate of wind energy.

Detailed ways

Below in conjunction with accompanying drawing and the present invention is further described.

Referring to Fig. 1, 2, 3, the present invention comprises a base 3 and a tower body 2 arranged on the base 3, the base 3 and the tower body 2 are hollow cylindrical structures, and a horn-shaped Hollow body 6, the cross-sectional area of the air inlet at the lower end of the hollow body 6 is greater than the cross-sectional area of the air outlet at the upper end, a wind wheel 4 is arranged at the air outlet, and the surface of the tower top 1 at the upper end of the tower body 2 is an arc-shaped curved surface 8. The solid part of the tower body 2 is provided with a control room and a motor room 5 connected with the wind wheel.

When the high-altitude wind flow 11 passes through the upper and lower surfaces of the tower top 1, a stroke difference is formed, and the wind speed flowing through the upper surface will be greater than the wind speed on the lower surface. The effect of this design will cause the wind flow 12 rising along the tower top to form an "airflow rising effect" , play the effect of drawing wind on the upwind flow 10 at the air inlet, and increase the energy density of the wind energy acting on the wind wheel 4 . Both the tower body and the base are hollow cylinders, and the solid part of the tower body builds a motor room and a control room 5, which can also be used as offices, lounges, etc., for the purpose of effectively utilizing space and saving construction costs. In Fig. 3, the hollow body 6 of the wind collecting tower is a device for collecting wind energy. The lower half of the hollow body 6 is formed by turning the curve 7 of the inner cavity of the tower to form a rotating body, and the upper half is cylindrical. The entire hollow body 6 runs through the tower top 1, The body 2 and the base 3 have an air inlet below and an air outlet above, and the cross-sectional area of the air inlet is greater than the cross-sectional area of the air outlet. Initially, the hot air 9 heated by solar energy on the ground rises along the curve 7 of the tower inner cavity of the hollow body 6, and the curve 7 of the tower inner cavity can lengthen the route of wind flow and effectively increase the wind speed. Furthermore, the rising wind flow 10 at the air inlet is affected by the pulling wind, and the wind speed is further increased, which acts on the wind wheel 4 to promote its rotation to generate electricity. Because the tower inner chamber curve 7 and the arc-shaped curved surface 8 of the tower top 1 of the present invention double increase the wind speed, the utilization rate of wind energy will be greatly improved, and the design purpose will be achieved.
