Mobile type rainwater collecting field structure

Abstract

The invention belongs to the technical field of rainwater collecting, storage and utilization structures and particularly relates to a mobile type rainwater collecting field structure. The mobile type rainwater collecting field structure is characterized by comprising a piece of rainwater collecting cloth and a rainwater storage facility; four corners of the rainwater collecting cloth are fixed through support frames; an outflow opening is formed in the rainwater collecting cloth; and one side of the outflow opening is connected with the rainwater storage facility through a water diversion pipe. The mobile type rainwater collecting field structure is simple and convenient to use, and can be put up or removed randomly at proper time and place according to needs; rainwater collecting, storage and utilization space can be expanded, and self-pressure water supply, land saving and water quality protection are realized; and the manufacturing cost is low, economic benefits and environmental benefits are remarkable and popularization and application are facilitated.

Description

(1) Technical field [0001] The invention relates to a movable rain-collecting field structure, which belongs to the technical field of rainwater storage and utilization structures. (2) Background technology [0002] Rainwater collection surfaces in traditional rainwater storage and utilization technologies are generally divided into three types: natural slopes, impermeable water surfaces of existing artificial buildings, and built special collection surfaces. A place with many shortcomings. [0003] First of all, the space for rainwater storage and utilization is limited. For example, in the semi-humid areas of North China, although natural slopes can be used as collection surfaces, the storage and utilization of rainwater is greatly restricted by the infiltration conditions of the underlying surface, topography and other factors. Restrictions, first of all, using natural slopes to collect rainwater, water storage facilities such as cellars and pools can only be built at th...

Problems solved by technology

[0003] First of all, the space for rainwater storage and utilization is limited. For example, in the semi-humid areas of North China, although natural slopes can be used as collection surfaces, the storage and utilization of rainwater is greatly restricted by the infiltration conditions of the underlying surface, topography and other factors. Restrictions, first of all, using natural slopes to collect rainwater, water storage facilities such as cellars and pools can only be built at the catchment point downstream of the slope, so it is required not only to have a suitable collection slope, but also to have a water pool downstream of the slope ( cellar), the two must be satisfied at the same time, and it will be more difficult to meet the requirements of water demand sites at the same time. In addition, in some areas with good infiltration conditions on the natural underlying surface, the collection efficiency is very low. If there is not enough collection The water area is not suitable for rainwater storage and utilization, such as in some areas where surface karst is developed; secondly, traditional natural slope rainwater collection, water storage facilities are built at the lowest point, and the water storage surface is usually lower than the surrounding surface height. When using water, the water must be manually lifted, especially for irrigation methods that require a certain pressure, such as drip irrigation, micro-sprinkler irrigation, etc., it is very troublesome to use a water pump to lift the water stored in the pool (cellar) to a high-level pool;

[0004] Finally, it needs to occupy land to build a special collection surface, and the rainwater is polluted by the surface and is no longer pure
