Description

Technical Field

[0001] This invention belongs to the field of new energy power generation technology, specifically relating to an inflatable power generation device and a collaborative control method based on the principle of artificial tornado vortex, which is particularly suitable for industrial waste heat recovery, distributed power supply in agricultural greenhouses, utilization of waste heat from air conditioning in high-rise buildings, and off-grid power supply scenarios in the field and remote areas. Background Technology

[0002] Existing tornado power generation devices are mostly steel structures, which are costly, non-foldable, and difficult to transport and install. They rely on natural vortex formation and cannot start stably in environments with weak heat sources and low wind speeds. The airflow inside the tower is turbulent and severe, resulting in large fluctuations in power output and low power generation efficiency. The separate installation of the wind turbine and generator leads to large energy transfer losses and low overall energy utilization. At the same time, a large amount of waste heat emitted from urban building air conditioning units, industrial production, and agricultural greenhouses is not effectively recovered and utilized, resulting in energy waste and thermal pollution. In addition, existing inflatable power generation towers have a single method of structural reinforcement, insufficient overall pressure and wind resistance, and lack an efficient wind-gathering and wind-controlling structure at the air inlet, failing to maximize the collection of heat source airflow and control of strong winds. This invention proposes a complete solution to all the above-mentioned technical pain points. Technical solution

[0003] An inflatable tornado power generation device includes an inflatable flexible tower assembly, a turbine current stabilization power generation assembly, a top dual-purpose wind control power generation assembly, an inflatable pressure stabilization assembly, a fixed base, a heat source introduction assembly, an air intake and wind gathering assembly, and a tower reinforcement assembly.

[0004] The main body of the inflatable flexible tower is made of high-strength, airtight, flexible material. It is a double-layered hollow vertical cone structure. The upper 10% section of the tower's total height is equipped with a 9° outward-opening diffuser structure. Multiple layers of annular inflatable reinforcing ribs are evenly arranged inside. Multiple independent reinforcing inflatable columns are evenly distributed in the middle of the double-layered inflatable structure. These independent reinforcing inflatable columns are sealed and connected to the double-layered tower and the annular inflatable reinforcing ribs and are independently inflated, which improves the overall rigidity, compressive strength, and wind load resistance of the tower after inflation.

[0005] The air intake and wind gathering component includes an automatic telescopic wind gathering plate, which is symmetrically hinged to the outer periphery of the heat source inlet and electrically connected to the intelligent control system. It can automatically adjust the telescopic and opening angles according to the size of the heat source airflow and the negative pressure value inside the tower, maximizing the gathering of heat source airflow and controlling the surrounding wind energy to protect the device and controllable power generation, and enhancing the thermal pressure rise effect.

[0006] The top-mounted dual-purpose wind-powered generator assembly is sealed and installed at the diffuser at the top of the tower, serving as a variable frequency wind-driven generator. In start / stabilize mode, it acts as a motor, actively drawing in air to establish a stable negative pressure within the tower, forcibly inducing and regulating the vortex pattern. In surplus airflow mode, it functions as a generator, driven by the rising airflow, achieving secondary recovery of air kinetic energy for auxiliary power generation. The intelligent control system collects real-time data on turbine speed, tower air pressure, and heat source airflow temperature, automatically switching the dual-purpose generator's operating mode and adjusting operating parameters in a closed-loop manner.

[0007] The bottom turbine flow stabilization and power generation component is located in the main airflow channel at the bottom of the tower. It includes a flow stabilization chamber, flow guide vanes, main turbine impeller, speed increaser and main generator. The flow guide vanes regulate and guide the rising airflow, completely eliminate turbulence, ensure that the main turbine impeller rotates at a uniform speed, and realize efficient, stable and continuous power generation by the main generator.

[0008] The heat source inlet introduces industrial waste heat, greenhouse hot air, or exhaust air from building air conditioning units from the lower part of the tower. It rises naturally using thermal pressure and drives the surrounding wind energy to form a basic vortex power. The device can be fixedly installed on the ground, roof, or building exterior wall, adapting to deployment needs in multiple scenarios.

[0009] The inflatable pressure stabilizing component is connected to the inflatable flexible tower body, the annular inflatable reinforcing rib, and the independently reinforced inflatable column, realizing integrated inflation, pressure stabilization and deflation. After deflation, it can be folded as a whole to reduce transportation and storage costs.

[0010] 1. Inflation Deployment: The main body of the tower, the annular inflatable reinforcing ribs, and the independently reinforced inflatable columns are inflated simultaneously through the inflatable pressure stabilizing components, and the tower body is self-erected and fixed to the ground, roof, or exterior wall of a building through the bottom fixed base; 2. Air Concentration and Guiding: The intelligent control system controls the automatic retractable air concentrator to adjust to the optimal opening and closing angle, and gathers the waste heat airflow from industrial, agricultural or building air conditioning through the heat source inlet, driving the surrounding air to form a preliminary spiral upward airflow; 3. Intelligent Vortex Control: The variable frequency wind turbine generator is activated to actively induce wind and create vortices in motor mode, stabilizing the negative pressure and vortex intensity inside the tower and eliminating airflow turbulence; 4. Dual power generation: The rising airflow drives the bottom main turbine impeller to rotate, and the main generator generates electricity; when there is excess airflow, the top dual-purpose unit switches to generator mode to recover surplus energy to assist in power generation, thus achieving dual power generation. 5. Shutdown and Storage: After shutting down the heat source input, the dual-purpose unit stops, and the tower body is folded up after venting for easy transportation, storage and secondary deployment.

Detailed Implementation

[0012] The tower is 10m high, with a 9° diffused opening at the top 1m. The double-layered tower is equipped with 8 sets of independently reinforced air columns, and the heat source inlet is equipped with 4 automatic retractable wind concentrators. The top is equipped with a 500W variable frequency dual-purpose machine, and the bottom is equipped with an 8kW main generator. During the day, the automatic retractable wind concentrators maximize wind gathering by utilizing the waste heat of the greenhouse and naturally creating vortices. At night, the dual-purpose machine actively draws in wind and intelligently stabilizes the voltage and controls the vortex, achieving 24-hour stable power supply with a speed fluctuation of ≤±3%, meeting the power supply needs of greenhouse irrigation, lighting, and ventilation.

[0013] The tower is 18m high, with a 9° diffused opening at the top 1.8m. The double-layered tower is equipped with 12 sets of independently reinforced air columns and 6 automatic telescopic wind concentrators. The top is equipped with a 2kW dual-purpose integrated unit. In response to the factory's waste heat and external wind fluctuations, the intelligent control system synchronously adjusts the opening and closing angle of the wind concentrators and the wind intensity of the dual-purpose unit to stabilize the vortex shape. The waste energy recovery efficiency is improved by 10%~20%, and the power generation parameters meet the requirements of low-voltage grid connection, allowing direct connection to the factory's power supply system.

[0014] The device is installed on the exterior walls or rooftop platforms of high-rise residential buildings and office buildings. The heat source inlet is directly connected to the exhaust duct of the building's air conditioning unit. The automatically retractable wind-gathering plate fits into the exhaust port of the air conditioning unit, collecting waste heat from the air conditioning and surrounding wind energy from all directions as a driving force. It utilizes the height of high-rise buildings to enhance the chimney effect, and with the independent reinforced inflatable column, it improves the wind resistance of the tower. The dual-purpose unit at the top actively controls the vortex to form a stable artificial tornado. The main turbine at the bottom works in conjunction with the dual-purpose unit at the top to generate electricity, which is directly recycled for corridor lighting, public facilities, security monitoring, elevator auxiliary power supply, etc., realizing the resource utilization of waste heat from building air conditioning and reducing the building's public energy consumption.
