Description

Technical Field

[0001] The utility model relates to the technical field of water resource management, in particular to a rainwater collection and storage device. Background Art

[0002] Water shortage is an increasingly serious problem worldwide; many areas, such as parts of Wuling Mountain and Mufu Mountain in Hubei Province, are facing a serious water crisis. This crisis not only affects people's daily lives, but also has a profound impact on various fields such as agriculture and industry. Therefore, it has become an urgent need to effectively utilize existing water resources, and rainwater is one of the important water resources that people can use.

[0003] Among these areas, there is a karst area called Mufu Mountain in eastern Hubei. This area specifically refers to a geographical area where the area of ​​exposed and semi-exposed carbonate karst mountains accounts for more than 30%. Such areas have special geographical environment and climatic conditions, which lead to common droughts. Therefore, the use of rainwater resources is an important way to obtain water resources in such areas. However, the terrain of such areas is steep and the slope is large, which is prone to soil erosion. When rainwater flows through these areas, it is easy to wash away the gravel, soil and other particles on the surface, forming turbid rainwater. These particles will not only pollute the water quality, but also may affect the normal infiltration of rainwater and the recharge of groundwater, hindering ecological development. Therefore, when using rainwater in such areas, it is necessary to fully consider these characteristics and adopt appropriate technologies and equipment to ensure the effective use of rainwater and the sustainable development of the ecological environment.

[0004] In the prior art, people usually use rainwater collection and storage equipment to achieve effective use of rainwater. However, when using such equipment, there are often many problems such as low rainwater utilization rate, poor ventilation, and difficulty in ensuring water resource hygiene; for example, the patent with publication number CN107447933A discloses a rainwater collection and treatment device on the roof of a building. Although the device disclosed in the patent can achieve the effect of rainwater utilization, the device has a low utilization rate of rainwater and is not equipped with ventilation facilities, which easily affects the air quality in the water storage tank, making it difficult to ensure water resource hygiene. Therefore, a new type of rainwater collection and storage device is urgently needed to solve the above problems.

[0005] The information disclosed in this background technology section is only used to deepen the understanding of the background technology of the present disclosure, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art known to those skilled in the art.

[0030] See also Figures 2 to 5 The purification device includes a water injection tank 21, a grit tank 22 and a water outlet tank 23. A water outlet pipe 24 is connected between the water outlet tank 23 and the water storage tank 1. The diameter of the water outlet pipe 24 is adapted to the water inlet 16. A water injection port 211 is provided on the top of the water injection tank 21, a ventilation hole 212 is provided on the upper side, and a drainage hole 224 is provided on the bottom.
