Rainwater collecting tank for non-porous ground

Abstract

The invention relates to a rainwater collecting tank, in particular to a rainwater collecting tank for non-porous ground, which is used for collecting and storing rainwater falling on the non-porous ground. The rainwater collecting tank is structurally characterized in that a water collecting opening capable of collecting water from the ground is arranged at the upper part of the rainwater collecting tank, a filtering device is arranged at the lower part of the rainwater collecting tank, one side of the filtering device is connected with a purification tank by a reaction tank, and a water outlet is arranged at the upper part of the purification tank; and a material changing port is arranged at the top of the reaction tank, a channel is arranged between the rainwater collecting tank and the purification tank, and a dredging opening is arranged on the wall of the rainwater collecting tank. The rainwater collecting tank can effectively collect, filter, purify and store rainwater falling on the non-porous ground, the collected rainwater can used for agricultural irrigation, city greening, industrial production and other aspects, and thus the rainwater can be used fully; and the rainwater collecting tank is simple to implement and convenient to maintain, by the adoption of the rainwater collecting tank, the problem of shortage of fresh water resource can be solved, and occurrence of flood due to overlarge rainfall can be avoided.

Description

technical field [0001] The invention relates to a rainwater catchment tank, specifically a rainwater catchment tank for collecting and storing rainwater falling on impermeable ground. Background technique [0002] At present, there are almost no rainwater collection devices in cities and highways. The ground is made of cement, asphalt, etc., and the rainwater cannot penetrate. The rainwater that falls on the ground directly flows into the drainage system and is discharged into the river. When the rainfall is large, it is also prone to flood disasters. Contents of the invention [0003] The purpose of the present invention is to provide a rainwater collection tank for collecting and storing rainwater falling on the impermeable ground, which can be filtered to obtain relatively clean fresh water, and the storage tank is easy to implement and maintain to prevent flood disasters. [0004] The technical scheme of the present invention is realized in this way: the structure of ...
