Abstract

The invention provides a power-free rainwater collection device which comprises M water collection tanks which are sequentially arranged from top to bottom. Each water collection tank is provided with a water inlet hole, a drain hole, a water feeding hole and an overflow hole, the water inlet hole is formed in the top, the drain hole is formed in the bottom, and the water feeding hole and the overflow hole are formed in the side wall. The height of the water feeding hole is lower than that of the overflow hole, the water inlet hole of the water collection tank on the most top is connected with a drain pipe of a roof, the water feeding hole of the water collection tank is connected with the water inlet hole of the lower and adjacent water collection tank by a drain stand pipe, the drain hole of the water collection tank is connected with a water facility by a drain pipe, and the overflow hole of the water collection tank is connected with the overflow pipe. A small water storage tank is only arranged on the wall of the side face of the outer side of a floor, so that land is saved. The principle that water flows downwards is used, electricity, a machine and manpower are not used, recycling of rainwater is achieved without needing power, tap water can be saved, and water treatment cost is reduced. The power-free rainwater collection device is energy-saving, emission-reducing, and environmental-friendly.

Description

technical field [0001] The invention relates to the technical field of rainwater recovery devices, in particular to a non-powered rainwater recovery device. Background technique [0002] Due to the increasing pollution of the earth and the scarcity of clean water sources, water shortages are common in the world. As a clean water source, it is very meaningful to collect rainwater scientifically and effectively. In cities, rainwater can be collected and stored systematically for use in green space irrigation, road spraying, toilet flushing, vehicle flushing, and landscape water replenishment, which can effectively relieve pressure on urban water supply and avoid water shortages and urban floods. [0003] At present, the rainwater collection methods commonly used in cities mainly include water collection on the top of roof buildings, water collection on the ground, roads, greening, public places and sports fields, and the most commonly used is water collection on the top of ro...
