Technical Field

The invention relates to the technical field of urban rainfall systems, in particular to an intelligent rainfall system for an urban dense area and a using method thereof.

Background

With the advance of urbanization and industrialization, the urban scale is continuously enlarged, the microclimate of the city is obviously changed, air pollutants and greenhouse gases are accumulated above the urban area, so that the air pollution is serious, the central temperature of the city is raised, the urban heat island effect is more serious, and the hot and arid degree in summer of China is aggravated. For example, extreme drought in summer in 2015 occurs in China, so that more than two thousand people in 48 cities in the country are damaged, the absolute crop harvest area reaches 403.9 kilo hectares, and the direct economic loss is 114.8 million yuan. In recent years, the southern and western cities in China have continuous high temperature in summer, for example, the Wuhan city, the Nanchang city, the Hangzhou city and the Changsha city last for over 20 days in 2019; the maximum temperature in 2019 of Chongqing city reaches 39.6 ℃ in summer.

The water resources in the south and the west of China are rich, and a large number of natural water bodies which are not fully utilized exist in cities in coastal and coastal areas, so that the method can be used for relieving the summer high-temperature condition of the cities in the south and the west, reducing the influence of a heat island effect and improving the living environment of urban residents. At present, a rainfall system aiming at a high-rise building group is not available, spraying can be carried out only on the roof of a single building, the cooling range is small, the cooling degree is limited, and the urban heat island effect cannot be effectively relieved; the building cooling system for a single building cannot realize whole-process intellectualization, cannot flexibly adjust the water spraying quantity and the spraying time, causes water resource waste, and has low energy-saving and environment-friendly values. Therefore, the development of an intelligent rainfall system capable of effectively solving the high-temperature problem of the building group in the urban dense area is urgently needed.

And when the measured temperature exceeds the set value and the water source cannot be directly extracted, the step 6) is carried out.

5) The intelligent control center control valve enables the pipeline I to be communicated with the pipeline III, the pipeline II is sealed, the intelligent control center controls the pumping power system, the water pump and the spraying system to be started again, water at a water source flows into the spraying system through the pumping power system, the water pump, the pipeline I and the pipeline III, the spraying system sprays water and cools down city building groups, and spraying is stopped until the temperature sensed by the intelligent sensor is lower than a set value.

6) The intelligent control center controls the valve to seal the pipeline I, the pipeline III is communicated with the pipeline II, the intelligent control center controls the spraying system to be started again, water of the water storage system flows into the spraying system through the pipeline II and the pipeline III, the spraying system sprays water and cools down city building groups until the temperature sensed by the intelligent sensor is lower than a set value or the water storage system is pumped out, and then the spraying is stopped.
