Description

Roof rainwater collection and utilization system

technical field

The utility model relates to a system for collecting and utilizing rainwater on roofs, which belongs to the technical field of buildings and relates to the field of urban planning and design.

Background technique

At present, there is water shortage in most parts of our country, which seriously affects the normal life of residents. The problem of water shortage will lead to drought of farmland and insufficient supply of water resources per capita. At the same time, excessive exploitation of groundwater will damage the groundwater environment and geological ecology. The recent continuous rainstorms in southern my country have caused floods in many places, causing precious water resources to be lost in vain. From this we can see two problems: one is the serious water shortage problem; the other is that the precious water resources have not been fully and rationally utilized.

Contents of the invention

In order to solve the above problems, the utility model provides a roof rainwater collection and utilization system. It provides a collection system that can not only reduce the peak flow of rainwater to alleviate the problem of urban waterlogging, but also make full use of rainwater resources. It is not only economical and environmentally friendly, but also simple in structure and saves materials.

The utility model is a roof rainwater collection and utilization system, which is characterized in that it includes: rainwater outlet (1), barbed wire (2), rainwater pipe (3), water collection pipe (4), municipal pipe (5), float valve (6) , water collection tank (7), clear water tank (8), water dividing wall (9), quartz sand (10), double-layer separation net (11), water pipe (12), water pump (13), faucet (14); rainwater pipe (3) There is a rainwater outlet (1) on the top, and a wire mesh (2) is installed inside the rainwater outlet (1); quartz sand (10) is laid below the sump (7), the sump (7) and the clear water pool (8) A water dividing wall (9) is provided between them, and a double-layer separating net (11) is provided at the bottom of the water dividing wall (9); a float valve (6) is provided between the sump (7) and the water collecting pipe (4), and The lower part of the water collection pipe (4) is connected to the municipal pipe network (5), the water collection pipe (4) is connected to the rainwater pipe (3), and the rainwater pipe (3) is connected to the roof; A water pipe (12) is arranged to stretch into the clear water pool (8), and a water tap (14) is provided above. The barbed wire (2) inside the rainwater outlet (1) can collect debris, which is convenient for regular cleaning and avoids blockage.

The bottom of the rainwater pipe (3) is connected to the water collection pipe (4), and the horizontally inclined water collection pipe (4) can effectively increase the runoff velocity of rainwater and save the consumption of the rainwater pipe (3).

The bottom of the water collection pipe (4) is sequentially connected with the municipal pipeline (5) and the sump (7), so that the rainwater can be discharged as soon as possible to avoid waterlogging.

The sump (7) is equipped with a ball float valve (6). When the rainwater in the sump (7) is full, the ball float valve (6) will block the bottom nozzle of the water collection pipe (4), and the excess rainwater will flow into the municipal pipe network (5).

The quartz sand (10) at the bottom of the sump (7) acts as a filter to purify rainwater.

The bottom of the water dividing wall (9) is provided with a double-layer separating net (11), and the pore diameter on the side adjacent to the quartz sand (10) is small, which can effectively prevent the quartz sand (10) from entering the clear water pool (8), and the other side The pore size is larger, so that the purified rainwater can quickly flow into the clear water pool (8).

The water pump (13) absorbs the filtered rainwater through the water pipe (12) under the action of power. When the purified rainwater level drops, the rainwater in the sump (7) continues to filter through the quartz sand (10) and flows into the clear water pool ( 8).

The water tap (14) obtains purified rainwater under the action of the water pump (13), which can be used for car washing, community greening irrigation, road cleaning and the like.

Compared with the prior art, the beneficial effects of the utility model are:

1. The connection distance between the rainwater pipe (3) and the water collection pipe (4) is very short, which can effectively save the amount of rainwater pipe (3), and the inclined water collection pipe (4) can increase the runoff speed of rainwater;

2. Compared with other methods, the purification method of quartz sand (10) has lower cost and convenient construction;

3. The construction method of the double-layer separating net (11) is simple, the price is low, and the construction is convenient;

4. The water collection pool (7) and the clean water pool (8) can be constructed at one time, which reduces the construction process, reduces the amount of engineering, and is simple in structure.
