Description

Technical Field

[0001] This utility model relates to the field of rainwater harvesting technology, specifically to a rainwater harvesting device for wind-powered green buildings. Background Technology

[0002] In today's era of pursuing sustainable development, green building has become an important direction for the construction industry. Rainwater, as a precious natural resource, is crucial for alleviating water shortages and reducing building operating costs through its effective recycling. Furthermore, combining rainwater harvesting systems with renewable energy sources further enhances the environmental and energy-saving attributes of buildings. However, current common rainwater harvesting devices have many drawbacks.

[0003] Most traditional rainwater harvesting systems rely solely on simple grilles for filtration. While the mesh of these grilles can intercept large debris such as leaves, twigs, and large pieces of plastic, they are ineffective against fine particles of silt and sand carried in rainwater. These fine particles flow into subsequent pipes and treatment equipment, accumulating over time and easily adhering to and depositing on the inner walls of the pipes, gradually narrowing their diameter and eventually causing poor flow or even complete blockage. This not only severely affects the normal operation of the rainwater harvesting system, increasing maintenance costs and workload, but can also lead to secondary disasters such as flooding due to poor drainage, threatening building safety.

[0004] Most existing rainwater harvesting systems do not fully consider the comprehensive utilization of energy, relying solely on external mains power to drive pumps and other equipment, failing to tap into the abundant renewable energy potential around buildings. In the current context of tight energy supplies and increasingly stringent environmental requirements, this energy utilization method is neither economical nor in line with the development concept of green buildings, and cannot achieve the energy conservation and emission reduction goals in the rainwater harvesting process. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned problems and provide a rainwater harvesting device for wind power generation green buildings. To achieve the above objective, this utility model adopts the following technical solution:

[0006] A wind-powered green building rainwater harvesting device includes a main body, which includes a power generation component, a collection component, and a treatment component. The power generation component is mounted on the treatment component. An inlet pipe is provided between the collection component and the treatment component. The treatment component includes a sedimentation tank with a rotating shaft in the middle. An impeller is mounted on the rotating shaft. The inlet pipe is axially arranged at the top of the sedimentation tank. The power generation component is used to drive the rotating shaft to rotate.

[0007] As an improvement, the grit chamber is equipped with a sludge hopper at the bottom, a sand discharge pipe on the sludge hopper, and a sand discharge pump on the sand discharge pipe. The sludge at the bottom of the sludge hopper is discharged from the sand discharge pipe by the sand discharge pump. An electric motor is installed at the top of the grit chamber, and the electric motor drives the rotating shaft to rotate.

[0008] As an improvement, the sedimentation tank is equipped with an outlet pipe, which is located above the sludge hopper and is connected to water-using equipment.

[0009] As an improvement, the power generation component includes several wind turbines and energy storage tanks. The wind turbines are evenly distributed on the top surface of the sedimentation tank and face different directions. The energy storage tanks are installed on the top surface of the sedimentation tank and are used to store the electrical energy generated by the wind turbines.

[0010] As an improvement, the collection assembly includes a rainwater collection tank with a grid on the top surface of the rainwater collection tank and an inlet pump on the inlet pipe.

[0011] As an improvement, the energy storage tank is electrically connected to the water inlet pump, the motor, and the sludge discharge pump.

[0012] The advantages of this utility model are:

[0013] 1. Compared to traditional rainwater harvesting devices that rely solely on bar filtration, this invention adds a sedimentation tank to the treatment components, promoting efficient sediment settling. Combined with a regular cleaning mechanism involving a sludge hopper and a sand pump, it effectively intercepts and removes sediment particles from rainwater, fundamentally solving the problem of pipe blockage caused by fine sediment accumulation. This significantly extends the maintenance cycle of the entire rainwater harvesting system, reducing operation and maintenance costs and the risk of failure.

[0014] 2. This utility model integrates wind power generation into a rainwater harvesting device. Through the coordinated operation of a multi-directional wind turbine layout and an intelligent energy storage box, it not only provides continuous and clean power for the device's own operation, but also feeds excess power back into the building's power grid for use by other electrical equipment. This fully taps the potential of renewable energy, aligns with the energy utilization concept of green buildings, effectively reduces the building's dependence on traditional grid power, and reduces carbon emissions.

[0025] The present invention will be described in detail below through specific embodiments to enable a better understanding of the present invention. However, the following embodiments do not limit the scope of protection of the present invention.

[0026] Example 1

[0027] This embodiment discloses a rainwater harvesting device for wind power generation green buildings.

[0028] like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment includes a device body 1, which includes a power generation component, a collection component, and a processing component. The power generation component is mounted on the processing component. A water inlet pipe 2 is provided between the collection component and the processing component. The processing component includes a sedimentation tank 3, with a rotating shaft 4 in the middle of the sedimentation tank 3. An impeller 5 is mounted on the rotating shaft 4. The water inlet pipe 2 is axially arranged at the top of the sedimentation tank 3. The power generation component is used to drive the rotating shaft 4 to rotate.

[0029] The sedimentation tank 3 is equipped with a sludge hopper 6 at the bottom, a sand discharge pipe 7 on the sludge hopper 6, and a sand discharge pump on the sand discharge pipe 7. The sludge at the bottom of the sludge hopper 6 is discharged from the sand discharge pipe 7 by the sand discharge pump. The sedimentation tank 3 is equipped with an electric motor 8 at the top, which drives the rotating shaft 4 to rotate.

[0030] A rotating shaft 4 runs longitudinally through the interior of the grit chamber 3, and an impeller 5 is securely mounted on the rotating shaft 4. The inlet pipe 2 is axially connected from the top of the grit chamber 3, and a motor 8 drives the rotating shaft 4 to rotate at high speed. A sludge hopper 6 is located at the bottom of the grit chamber 3; its special conical structure facilitates the sedimentation and accumulation of sludge. A sand discharge pipe 7 is connected to the bottom of the sludge hopper 6, and a high-efficiency sand discharge pump is installed on the sand discharge pipe 7 to periodically discharge the deposited sludge from the system, maintaining the efficient operation of the grit chamber 3. An additional motor 8 is installed at the top of the grit chamber 3, which drives the rotating shaft 4 to rotate, ensuring the continuity of the treatment process.

[0031] The sedimentation tank 3 is equipped with an outlet pipe 9, which is located above the sludge hopper 6 and is connected to the water-using equipment.

[0032] The upper part of the sedimentation tank 3 is also equipped with an outlet pipe 9, which is located above the sludge hopper 6. After the sedimentation and purification treatment, the rainwater flows out smoothly from here and can be directly connected to various water-using equipment in the building to realize the secondary utilization of rainwater resources.

[0033] The power generation assembly includes several wind turbines 10 and energy storage tanks 11. The wind turbines 10 are evenly distributed on the top surface of the sedimentation tank 3, with different orientations. The energy storage tanks 11 are installed on the top surface of the sedimentation tank 3 and are used to store the electrical energy generated by the wind turbines 10.

[0034] The power generation unit, located above the treatment unit, consists of multiple wind turbines 10 and an energy storage tank 11. The wind turbines 10 are evenly distributed on the top surface of the sedimentation tank 3, each facing a different direction, allowing them to capture incoming wind from all directions and ensuring continuous and stable power generation. The energy storage tank 11, also located on the top surface of the sedimentation tank 3, integrates an advanced power management system. This system not only efficiently converts the unstable AC power generated by the wind turbines 10 into stable DC power, but also features intelligent charge and discharge control functions to properly store electrical energy, providing a reliable power supply for all electrical equipment within the unit.

[0035] The collection component includes a rainwater collection tank 12, with a grid on the top surface of the rainwater collection tank 12 and an inlet pump on the inlet pipe 2.

[0036] The collection component centers on a rainwater collection tank 12, with a grille on its top surface serving as the first line of defense against rainwater entering the system, effectively blocking large debris. The bottom of the rainwater collection tank 12 is connected to the treatment component via an inlet pipe 2, which is equipped with an intelligent inlet pump. This pump can automatically start and stop based on changes in the water level within the treatment component or preset time intervals, precisely controlling the rainwater delivery flow and timing to ensure seamless integration between rainwater collection and subsequent treatment processes.

[0037] The storage tank 11 is electrically connected to the water inlet pump, the motor 8, and the sludge discharge pump.

[0038] During rainfall, rainwater first gathers in the rainwater collection tank 12, where the top grille acts as a preliminary filter, intercepting large floating objects such as leaves and branches to prevent them from entering subsequent pipes. As rainwater accumulates, when the preset start-up conditions for the inlet pump are met (such as the water level rising to a specific height or reaching a timed start-up time), the inlet pump quickly starts, forcefully pumping the rainwater into the grit chamber 3 through the inlet pipe 2. Under the influence of swirling current, the silt particles in the rainwater are accelerated to the bottom of the tank due to centrifugal force, accumulating at the bottom of the sludge hopper 6. The wind turbines 10 distributed on the top surface of the grit chamber 3 constantly capture wind power, and the built-in generator operates to generate electricity. The generated electricity is transmitted to the power storage box 11 in real time. According to the internally preset intelligent control strategy, the power storage box 11 prioritizes power supply to key electrical equipment such as the inlet pump, motor 8, and sludge pump.

[0039] The specific embodiments of this utility model have been described in detail above, but they are merely examples, and this utility model is not equivalent to the specific embodiments described above. For those skilled in the art, any equivalent modifications and substitutions to this utility model are also within the scope of this utility model. Therefore, all equivalent changes and modifications made without departing from the spirit and scope of this utility model should be covered within the scope of this utility model.
