The invention relates to a facility for collecting, storing and utilizing rainwater, which is used for reducing direct rainwater discharge, saving water resources and improving water environment and water ecology.

Description

Rainwater collecting, storing and recycling facility capable of automatically replenishing water

Technical Field

The invention relates to a facility for collecting, storing and recycling rainwater, in particular to a facility for recycling rainwater, saving water and energy.

Background

In recent years, with the continuous high-speed development of economy and climate change of China, the shortage of water resources is a major problem faced by human beings, and in order to relieve water pressure, people find various feasible methods, advocate water conservation and water recycling, and have great significance for human beings by reasonably utilizing rainwater as a natural water resource. The sponge city is a rainwater management system implemented for reducing flood disasters and saving water resources.

The invention aims to provide a facility for collecting, storing and recycling rainwater, which saves occupied land, is simple to maintain, beautifies the environment and can be used for sponge city construction, city wetland maintenance, rainwater management and the like.

Disclosure of Invention

To achieve the above object, the present invention provides the following support: and reasonably planning according to the landform, designing the capacity and structure of the water pool by matching with the area of the peripheral green land, and reasonably selecting aquatic plants.

Two sets of pump systems are arranged in a water collecting pit at the bottom of the underground water tank, one set of pump system automatically supplements water to the sunken surface water tank through the water level controller to ensure the growth of plants in the water, and the other set of pump system pumps the water for irrigating greenbelts and nursery stocks and cleaning road and ground.

Compared with the prior art, the invention has the following beneficial effects: the invention has the advantages that the water storage tank is arranged underground and does not occupy the ground area, the sunken ground surface water tank is arranged above the underground water tank and is part of the green landscape, the plants in the water have ornamental value and can purify the surrounding air and beautify the environment. The surface water pool provides filtered purified water for the underground water pool for storage, the underground water pool provides a water supplementing source for the surface water pool, and the automatic water supplementing system monitors the water level condition according to a water level meter of the surface water pool and automatically starts the water supplementing pump system to supplement water when the water level is lower than the designed lowest water level.

FIG. 1 is a cross-sectional view of the present invention.

In the figure: 1-a sand-settling tank, 2-a rainwater filter, 3-an underground water tank, 4-a ground-sinking water tank, 5-a filter layer of the ground-sinking water tank, 6-an overflow pipe of the sinking water tank, 7-an underground water tank water replenishing pump, 8-an underground water tank water taking pump, 9-a water inlet pipeline system, 10-a water outlet pipeline system and 11-aquatic plants.

Detailed Description

The operation of the present invention will now be described with reference to cross-sectional views thereof, it being understood that the operation described is not intended to be a complete embodiment. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Please refer to fig. 1:

the natural process designed by the invention comprises the following steps: when raining, rainwater flows to the sand basin (1) in a concentrated manner and flows into the underground reservoir (3) through the filter (2). The sink type water tank (4) receives rainwater at the same time, the rainwater flows into the underground water storage tank (3) through the percolation layer, and when the rainwater in the sink type water tank is excessive, the rainwater flows into the underground water storage tank (3) through the overflow pipe (6). The invention designs an automatic process: the water level gauge is arranged in the sunken water tank, when the water level in the sunken water tank is lower than a designed water level, the water pump is automatically started to replenish water, and when the water level reaches the designed high water level, the water pump automatically stops. The invention designs an automatic manual process: and manually starting a water pump to perform greening watering and ground flushing.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
