Description

Stationary water storage device for rainwater collection

technical field

The utility model relates to a device in the technical field of water-saving engineering, in particular to a fixed water storage device for collecting rainwater.

Background technique

my country's water resources are seriously insufficient. At present, the national water shortage in a normal year is nearly 40 billion cubic meters. More than 400 of the more than 660 cities in the country are short of water, of which nearly 130 are seriously short of water, and 14 of the 18 major coastal cities lack of water. Especially in big cities such as Beijing and Tianjin, there will be serious water crises in successive dry years. At present, Beijing has experienced drought and little rain for five consecutive years, and the most severe water supply situation since the founding of the People's Republic of China has emerged. If no measures are taken to actively deal with it, it will have a great impact on the capital's industrial and agricultural production, people's lives, and the success of the Olympic Games. Due to the concentration of rainfall seasons in most areas of my country and the reduction of the permeable area of the ground due to increasing urbanization, most of the runoff generated by heavy rains flows into the ocean in vain. If the urban rainwater is fully intercepted and stored, it can be used to flush toilets, sprinkle roads, water lawns, replenish water features, and even be used for circulating cooling water and firefighting water; at the same time, it will also reduce the flow into the rainwater drainage system and improve the urban flood drainage system. reliability and reduce urban flood disasters. Urban rainwater contains leaves and silt, and current water storage devices generally do not have the functions of removing leaves and silt. Therefore, the collection device of urban rainwater is the urgent need of the economic development and environmental beautification construction of each water-deficient city in my country today.

Found through document retrieval to prior art, Chinese Patent Publication No. 1536178A, disclosure date is October 13, 2004, and patent application No. 03138439.0, patent name is: rainwater collection and filling system. The patent is for a rainwater collection and filling device comprising a container with a collection cone positioned above it. Between the outlet at the bottom of the cone and the inlet at the top of the vessel is a sediment trap comprising an annular chamber. An inlet tube having an opening near its upper end extends into the chamber so that when the chamber overflows in use, the container is filled. The discharge valve allows flushing of the sediment trap. The rainwater harvesting device forms part of a system including storage, purification and filling equipment. The main disadvantages of this utility model are: 1) The device lacks the function of removing leaves, and substances such as leaves and small dead branches enter the rainwater collection device, which seriously affects the water quality; 2) Airborne dirt and dust accumulate on the roof , the water quality in the early stage of the heavy rain is very poor, containing insects, birds and animal excrement, and industrial pollutants, and the concentration of sediment, BOD, COD, etc. is high. Said device automatically clears the silt in the device, and the bottom water of poor water quality in the device cannot be automatically removed by subsequent excess rainwater.
