Airport rainwater collecting utilizing device

Abstract

The invention provides an airport rainwater collecting utilizing device which comprises a collecting pot, a water tank, a wind-driven generator, a speed reducer and using cabinets. The collecting potis fixed to the portion above the water tank, a supporting frame is fixedly arranged at the lower end of the water tank, the two using cabinets are fixedly arranged at the lower end of the supportingframe, the supporting frame is of an L-shaped structure and comprises a horizontal plate and a vertical plate, the horizontal plate is fixed between the water tank and the using cabinets, the length of the horizontal plate is larger than the width of the water tank, the four edges of the horizontal plate stretch out of the water tank, the vertical plate is fixed to one end of the horizontal plate,the speed reducer is installed at the upper end of the vertical plate, and the speed reducer is electrically connected with the wind-driven generator. The airport rainwater collecting utilizing device has the advantages that the integrated functions of collecting, filtering, purifying and applying rainwater are achieved, wind energy of an airport is used for supplying power to the speed reducer,the filtering efficiency is improved, the collected rainwater is finely filtered, and dust, dirt, bacteria and the like in rainwater can be filtered away.

Description

technical field [0001] The invention belongs to the technical field of water resources and environment, and in particular relates to an airport rainwater collection and utilization device. Background technique [0002] Urban construction has resulted in a large number of impervious surfaces, roofs, concrete and asphalt surfaces. The runoff coefficient of such road surfaces is generally 0.9, which means that nearly 90% of the rainfall will form surface runoff loss. This is not only a huge waste of water resources, but also It also increases the burden on urban drainage facilities and increases the probability of urban rainwater flood disasters. According to relevant statistical data, more than 400 of the more than 600 cities in the country are short of water, and 110 are seriously short of water. On the one hand, urban water resources are scarce, and on the other hand, urban waterlogging and runoff pollution frequently occur. [0003] Due to the scarcity of water resources,...

Problems solved by technology

However, the existing rainwater harvesting system works by collecting and purifying rainwater in a unified manner, without distinguishing between rainwater usage and corresponding treatment, which leads to low working efficiency of the overall treatment system and wastes a lot of rainwater resources.
