Rainwater collection cellar multistage desilting system

Abstract

A rainwater collection cellar multistage desilting system comprises a first-stage desilting tank, a second-stage desilting tank and a third-stage desilting tank. The first-stage desilting tank comprises a horn-shaped tank body, the large end of the horn-shaped tank body is in the water inlet direction, and a labyrinth type buffer structure is arranged on the inner bottom surface of the horn-shapedtank body. The second-stage desilting tank comprises a first circular tank body, and the left end and the right end of the first circular tank body are communicated with the first-stage desilting tank and the third-stage desilting tank through water passing openings respectively. The third-stage desilting tank comprises a second circular tank body; the second circular tank body is mounted at thetop of the cellar and is communicated with the cellar through a cellar water inlet. The rainwater collection cellar multistage desilting system improves the utilization rate of a cellar and prolongs the service life of the cellar.

Description

technical field [0001] The invention relates to a rain-collecting water cellar, in particular to a multi-stage sedimentation system for a rain-collecting water cellar, which is suitable for a water cellar or a small pool for collecting rain and storing water on slopes or soil roads in rural areas in mountainous areas. Background technique [0002] The total amount of water resources in my country is large, but the per capita share is small. Due to the uneven distribution of precipitation in time and space, the overall land area is mostly mountainous, and the problem of water resource shortage is becoming more and more serious, especially in mountainous areas. According to the survey, some rural people in mountainous areas mostly use rainwater collection to store drinking water and irrigation water sources, and water cellars are one of the important means to solve water sources in mountainous rural areas. According to statistics, the rural population decreased by 140 million ...

AI Technical Summary

Problems solved by technology

According to the survey, most of the water cellars in mountainous areas currently have serious sedimentation, shortened service life of water cellars, difficulties in later maintenance, and water storage capacity of water cellars is decreasing year by year, which cannot meet the needs of rural water supply and farmers' water use

[0004] At present, most mountainous rural rainwater cellars do not have sand settling and filtering facilities. The sand settling facilities of some water cellars use two rectangular settling tanks for sand settling. When the rainwater converges, the water flows directly into the settling settl
