Abstract
Description
[0001] The present application relates to the field of energy-saving and emission-reduction buildings, and in particular to a power generation device based on building heat flow and natural wind energy. Technical Background
[0002] Building energy conservation is an eternal topic. As petrochemical resources are becoming increasingly depleted, the use of new energy sources such as solar energy and wind energy is gradually maturing. It is also necessary to improve the huge daily energy consumption of building operations. Therefore, it is urgent to use the energy-consuming heat inside the building in combination with solar energy and natural wind energy to meet the requirements of low carbon, emission reduction, environmental protection, and greenness. Therefore, we propose this application: a power generation device based on building heat flow and natural wind energy (the heat flow here refers to the thermal flow, which we refer to as heat flow). Summary of the invention
[0003] In order to reduce carbon emissions and energy consumption in buildings, the present application provides a power generation device based on building heat flow and natural wind energy; its notable features are: it combines the internal heat energy of the building and solar energy with natural wind energy, and combines these three energies together to generate electricity using a generator assembly, thereby realizing energy conversion; it includes a generator assembly installed at the center of an arc-shaped bracket based on the top of the building, the arc-shaped bracket is welded by aluminum I-beams and round aluminum tubes; the rotating axis of the rotor shaft in the generator assembly is perpendicular to the ground; the arc-shaped bracket is installed at the top of the building, and aluminum I-beams are used at the vertical positions of the four symmetrical walls of the building and fixed to the wall with bolts The upper curved surface of the arc-shaped bracket is paved and sealed with tempered glass, and the lower curved surface is paved and sealed with aluminum-plastic panels (or tempered glass) to form a heat flow channel in the internal cavity; the arc-shaped bracket has an opening on the top floor of the building, and the four corners are ventilated; the arc-shaped bracket is welded with aluminum I-shaped profiles (aluminum I-beams) vertically fixed on the four vertical surfaces of the building body, and tempered glass is laid on the outer surface to form a sealed glass cover; the heat flow channel is a cavity composed of a glass cover installed on the outer surface of the building, an aluminum-plastic panel pasted on the lower part of the arc-shaped bracket, and the vertical walls around the building; the glass cover and the outer surface of the building wall form the outer surface of the channel and are sealed with the upper curved surface of the arc-shaped bracket. The heat flow channel surface is sealed and connected with the lower arc surface (the heat flow channel cavity plane paved with aluminum-plastic panels), and the lower arc surface is seamlessly connected with the vertical surface of the building body, so that it becomes a heat flow channel in the inner cavity of an integral glass cover shell, and a circular hollow heat flow outlet is left at the center of the top of the integral glass cover; the diameter of the circular hollow heat flow outlet matches the diameter of the heat flow turbine of the generator, and the heat flow is discharged from the circular hollow heat flow channel outlet; the air flow enters the inner cavity of the channel space from the glass skirt position of the channel space formed by the building body and the glass cover, and the air flow heated by the energy inside the building flows out from the opening opened in the building wall equipped with a beam cover; and the channel A beam cover is installed on the outer surface and sealed with the wall to prevent air flow backflow; therefore, the heat flow in the room flows out into the channel through the beam cover, and the heated gas flows along the heat flow channel. Because the hot air flow in the heat flow channel rises (greenhouse effect, hot air flows upward), and the air flow at the top forms a heat flow due to the further heating of the gas inside the cavity of the curved glass cover by sunlight, and this heat flow is further accelerated; the accelerated heat flow forms a rotating heat flow along the curved bracket bend plate (the bend plate is welded to the center end of the aluminum I-beam), and the bend plate is welded to the end of the center part of the curved bracket. The rotating heat flow and natural wind force form a driving force to make the generator assembly generate electricity. The generator assembly consists of a heat flow turbine component and an inner rotor component; it includes a plurality of generating coils installed on the inner wall of the turbine end cover, evenly distributed and coaxial with the turbine, and the two ends of the coils are respectively connected to copper rings 1 and 2, and the current is led out through carbon brushes, which can be connected to the load application through wires; the carbon brush fulcrum is fixed at the lower part of the lower arc surface; and the heat flow passes through the turbine blades and is discharged from the circular hollow outlet in the center of the glass cover.The inner rotor component of the generator assembly is composed of multiple magnetic steel sheets evenly fixed on the rotor shaft. The number of magnetic steel sheets is equal to the generating coil. The inner rotor shaft is coaxial with the thermal flow turbine and its upper part is installed on the shaft sleeve at the top center of the arc bracket. The inner rotor shaft is fixed with upper and lower wind impellers. Natural wind blows the upper and lower impellers to make the inner rotor rotate clockwise (opposite to the rotation direction of the thermal flow turbine). In this way, the building thermal energy, solar energy and natural wind energy are converted into electrical energy through the generator assembly. The generator assembly has a higher power density than the generator of the same volume. At the same time, the power generation system that relies on the building can be made of carbon fiber except for the coil, magnetic steel and copper ring, which is relatively light and relatively reduces the construction cost.
[0004] The present application is a creative idea of relying on buildings to collect the internal heat energy of the building, the solar energy received by the building surface and the natural wind energy, and convert the energy into electrical energy with a generator assembly. Its notable features are that the glass cover and the building window are connected and sealed with a square frame, so that the building interior can be ventilated with the outside, and the building wall is opened and a guide cover is installed to make the heat flow inside the building flow to the heat flow channel. Because the air flow in the heat flow channel has a speed that can generate internal and external negative pressure, the air flow will not flow back; the structure of the curved plate welded at the center of the arc-shaped bracket of the building not only plays a supporting role but also can guide the heat flow into a rotating heat flow; the arc-shaped bracket of the building is constructed to leave a cavity with the roof of the building, and the four corners are ventilated without affecting the original design function of the building, and the upper and lower ends of the inner rotor of the generator assembly are equipped with wind impellers, and the bottom end of the inner rotor shaft is supported by a support frame, and the support frame is installed and adjusted to an appropriate height before being fixed on the top surface of the building. The present application has a simple and inexpensive structure, and utilizes the building's thermal energy, solar energy, and natural wind energy to generate electricity using a generator assembly, enabling the building to achieve the realistic requirements of low carbon, emission reduction, greenness, and environmental protection.
