Solar energy integration wind power generation device

Abstract

A solar energy-integrated induced air power generation device comprises a pedestal and a tower body installed on the pedestal. A horn-shaped hollow body is arranged inside the tower body, the cross-sectional area of an air inlet port at the lower end of the hollow body is larger than that of an air outlet port at the upper end of the hollow body, a wind wheel is arranged at the air outlet port and connected with a control room and a motor room, and the surface of the tower top at the upper end of the tower body is an arch-shaped curved surface. In the inventive power generation device, the middle part of the tower body is designed to be horn-shaped, when sunlight irradiates ground, the thermal airflow on the ground heated by solar energy is expanded under heat and ascends to form ascending airflow at the air inlet port, and the ascending speed is faster and faster, so that the energy density of the air at the air outlet port is much higher than that of the air at the air inlet port and high enough to push a wind wheel generator to generate electricity. In addition, the tower top is designed to be an arc-shaped curved surface, so that the high-altitude airflow flowing through the tower top flows along the tower top to form airflow ascending along the tower top, which may take updraft action on the ascending heated air inside the tower body, so as to remarkably improve the wind energy utilization ratio.

Description

technical field [0001] 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 [0002] 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 [0003] The purpose of the present invention is to overcome the abo...
