Description

Technical Field

[0001] The invention relates to the technical field of rainwater collection, and in particular to a rooftop rainwater collection and utilization structure and method designed for green buildings. Background Art

[0002] Green building refers to the maximum resource conservation throughout the entire life cycle of the building, including energy conservation, land conservation, water conservation, material conservation, etc., to protect the environment and reduce pollution, provide people with healthy, comfortable and efficient use space, and buildings that coexist harmoniously with nature. In daily life, people's daily water all comes from tap water, especially in some cities with tight water resources. The price of tap water has continued to rise in recent years, so saving water is not only a protection of resources and the environment, but also directly related to people's economic savings. For example, most rainwater from the roof flows away directly, wasting a lot of water resources. Therefore, we should make full use of the rainwater resources collected in the house, increase the utilization rate of water through biological purification, and reduce the consumption of tap water resources. Moreover, rainwater is the main water replenishment resource in my country's rural water-scarce areas.

[0003] Most building roof structures are insulated by heat-insulating materials. When the temperature is high in summer, the heat-insulating effect of the building roof is poor, which makes the indoor temperature high and affects the living comfort.

[0014] 2. The rooftop rainwater collection and utilization structure and method designed in this green building directly uses the heat-insulating collection plate and the isolation layer as the rooftop rainproof structure. When the motor drives several groups of heat-insulating collection plates to achieve synchronous rotation through the driving transmission structure, gears and synchronous pull ropes, so that the several heat-insulating collection plates are at a 50° angle to the top of the house, a diversion channel is formed by the isolation layer partially submerged in the contact surface between the first group of plates and the roof frame, so that the rainwater is guided to the inner cavity of the collection bin through the diversion channel formed by the isolation layer partially submerged, and the rainwater is filtered through the filter material by setting the filter material in the inner cavity of the collection bin, and the diversion port opened at the bottom of the collection bin is used to transmit the rainwater to the inner cavity of the water storage tank through the diversion port, thereby achieving collection.
