Tower base automatic ventilation system for thermal convective wind power generation device

1:

• A tower-based ventilation system for thermal convective wind power generation, comprising:
• a vertically extending duct body, configured to convey air from a lower end of the duct body to an upper end of the duct body;
• said duct body comprising a first portion, a second portion, and a narrow portion, the first portion comprising an air intake chamber, the second portion comprising an air outlet chamber, the narrow portion connecting the first portion and the second portion;
• and
• a power generator disposed in the air outlet chamber and comprising a shaft operatively coupled to a turbine, wherein the conveyed air drives the turbine to rotate and the turbine drives the generator to produce electrical power,
• wherein the first portion, the narrow portion, and the second portion of the duct body jointly form a Venturi channel, the first portion defining an air intake opening in the lower end of the duct body, the second portion defining an air outlet opening in the upper end of the duct body, the narrow portion defining a reduced cross-section of the Venturi channel between the air intake opening and air outlet opening, wherein a flow rate of the conveyed air increases from the lower end of the duct body toward a reduced cross-section of the narrow portion and a pressure of the conveyed air decreases from the lower end of the duct body toward the reduced cross-section of the narrow portion, and wherein the conveyed air moves linearly in a moving direction along the duct body from the lower end to the upper end to pass through the Venturi channel.
