[0002] With the requirements of environmental protection, renewable energy is increasingly used in people's lives. Renewable energy mainly includes solar energy, wind energy, geothermal energy, etc. Wind energy is a clean, safe, renewable green energy.
[0003] At present, with the development and promotion of green buildings, renewable energy has been applied to a certain extent, such as solar water heating and solar power generation technologies have become mature, but the application of wind power generation in buildings is very limited. Wind resources are a renewable energy source, and this resource is very abundant on the tops of high-rise and super high-rise buildings. There are skylights for lighting and air ducts for ventilation on the tops of high-rise and super high-rise buildings. Due to the combined effects of thermal pressure and wind pressure, a chimney effect is formed, which generates a continuous airflow in the air duct.
[0004] At present, the airflow in the air duct has not been well utilized, and most of the existing rooftop wind power generation methods use natural wind to generate electricity, and the power generation capacity is limited. Summary of the invention

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] Reference Figure 1-3A rooftop pipeline power generation device comprises an air duct 4 arranged on a roof platform A, and a power generation component arranged on the upper part of the air duct 4, characterized in that the lower end of the air duct 4 is provided with a bottom vent 41 extending through to the lower part of the building, and the upper end of the air duct 4 is provided with a first exhaust port 42. The air duct 4 is generally arranged inside the building or in the light well and ventilation well of the building. Under the action of wind pressure and thermal pressure alone or together, a chimney effect is formed between the first exhaust port 42 above the air duct 4 and the bottom vent 41 at the lower part of the building, and airflow is generated in the air duct 4. In most cases, the airflow flows upward from the bottom vent 41 and is discharged from the first exhaust port 42, and the power generation component is driven by the airflow to generate wind power.
[0023] The power generation assembly includes a generator 2 disposed above the first air outlet 42 and a blade fan 21 fixedly connected to the main shaft of the rotor of the generator 2. The generator 2 is mounted on the roof platform A through a mounting frame 1, and the blade fan 21 is disposed in the air duct 4. The airflow flowing through the air duct 4 drives the blade fan 21 to rotate, and the blade fan 21 drives the rotor of the generator 2 to rotate to generate current, and the generated current can be stored or connected to the power grid. This application provides an application idea of clean energy in buildings by applying the natural airflow in the air duct.
[0024] Based on the above technical solution, under the action of the chimney effect, there will be a continuous airflow in the air duct 4 that runs from bottom to top inside the building. The airflow drives the blades 21 of the power generation component to rotate, and then drives the rotor of the generator 2 to rotate to generate electricity. The airflow that always flows in the air duct 4 is utilized to power the electrical equipment on the roof. Although the amount of electricity generated by a single power generation component is small, generating electricity through multiple power generation components set in the air duct 4 on the roof can also provide a good solution for green buildings and clean energy.
[0025] In this technical solution, if Figure 1-3 As shown, a plurality of second air outlets 43 are evenly provided on the side wall of the air duct 4 corresponding to the blades 21. The second air outlets 43 can improve the efficiency of the airflow in and out, and the airflow entering the air duct 4 or entering from the bottom vent 41 is discharged through the second air outlets 43. Through the design of the second air outlets 43, the airflow in the air duct 4 can flow smoothly, ensuring that the air intake in the air duct 4 is sufficient, and avoiding intermittent interruption of the airflow to affect the power generation efficiency of the power generation component.
[0026] In this technical solution, if Figure 1 and 2 As shown, the power generation component is also provided with a storage battery 5 electrically connected to the generator 2, which is used to store the power sent by the generator 2. For power generation components with a small power generation capacity, there is no need to be connected to the power grid. The power generated by the generator 2 can be sent to the storage battery 5 for storage, and the storage battery 5 can be used to supply power when needed, which is convenient for the use of electrical equipment.
[0027] In this technical solution, if Figure 1 and 2 As shown, the battery 5 is electrically connected to the electrical equipment to supply power to the electrical equipment, and the electrical equipment includes an aviation warning light 6, a roof signal tower, and a roof sign. The battery 5 can be used to supply power to the aviation warning light 6 on a high-rise building, and can also be used to supply power to the light sign, signal tower, etc. on the high-rise building. For a power generation component with a large power generation capacity, it can also continue to supply power to other relatively low power consumption equipment in the building to save power consumption, providing a solution for green buildings.
[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
