Abstract

The present application discloses a roof rainwater collector, which relates to the field of rainwater utilization. The roof rainwater naturally flows into the ground installed on the ground through the rainwater collection tank installed under the eaves, the rainwater bucket and the standpipe installed on the eaves wall. Rainwater tank, store it and take it at any time. It solves the problems of cloudy rainwater and inconvenient use of rainwater stored in cellars in arid areas in western my country, and can be vigorously popularized and applied as a practical water-saving technology in rural areas.

Description

A roof rainwater catcher

technical field

This application relates to rainwater utilization.

Background technique

At present, cellars are widely used to collect rainwater in rural areas in arid areas such as Northwest my country, which conveniently and better solves the problem of drinking water for humans and animals in water-scarce areas. , making the rainwater dirty and affecting its use; on the other hand, it is also inconvenient to get water from the cellar. How to make the collected rainwater clean and easy to use is a topic that urgently needs to be studied.

Contents of the invention

The purpose of the present invention is to ensure that the collected rainwater is clean and convenient to take, and its technical scheme is as follows:

1. Install a rainwater tank on the ground to store rainwater;

2. There is an inspection port on the top surface of the rainwater tank, a water inlet on the lower part of one side, an overflow port on the upper part of the other side, and a water outlet and a water valve on the bottom or the lower part of one side;

3. Right below the eaves outside the house wall, along the direction of the wall, install and fix the strip collection tank to the eaves wall, and make the bottom of the tank have a certain slope along the direction of the wall, so that rainwater can flow into the strip collection tank flow;

4. Install a rainwater bucket at the lower end of the strip collection tank to connect it, so that the rainwater in the strip collection tank can be gathered in the rainwater bucket;

5. Cover the notch of the strip collection tank and the top of the rainwater bucket with a grate and fix it to prevent plant stems, leaves, weeds, etc. from falling into the collection tank and rainwater bucket;

6. Install a standpipe on the eaves wall so that the upper opening is connected to the rainwater bucket, and the lower opening is connected to the rainwater tank through an elbow connector.

The rainwater storage process is: rainwater flows from the roof into the strip collection tank, then flows into the rainwater bucket, and flows into the rainwater tank through the standpipe, the elbow connector and the water inlet of the rainwater tank.

The water inlet should be positioned as low as possible on the rainwater tank in order to eliminate the noise caused by the rainwater flowing into the rainwater tank.

The application has the following positive effects:

1) Rainwater is relatively clean and hygienic, and can be directly used for laundry, washing hands and face, watering trees, flowers and vegetables, washing vegetables, and water for poultry and livestock, etc. The water saving effect is remarkable and it is convenient to fetch water;

2) It is not easy to be polluted during the rainwater storage process;

3) Rainwater will not seep and lose;

4) The equipment is simple to manufacture and low in cost.

Detailed ways

As shown in the attached picture, the rainwater tank is made of thin steel plate first, the water inlet is located at the lower part of one side of the rainwater tank, the water outlet is located at the lower part of the other side of the rainwater tank, the overflow is located at the upper part of one side of the rainwater tank, and the top surface of the rainwater tank There is an inspection port and a cover, and a sewage outlet is provided on the bottom of the rainwater tank, and then the rainwater tank is placed on the ground support;

On the eaves of the house, fix the angle steel with expansion bolts, fix the strip collection tank to the angle steel with bolts according to the 5% slope along the wall, fix the rainwater bucket to the angle steel, and connect the strip collection tank and rainwater bucket connect them;

Bind the wire grid to the upper edge of the strip collection tank and the upper mouth of the rainwater bucket to prevent leaves, branches and other debris from falling into the tank and bucket;

Install a PVC-U standpipe so that the upper port is firmly connected to the rainwater bucket, the lower port is firmly connected to the water inlet of the rainwater tank through an elbow connector, and the middle is fixed to the wall with a clip;

The strip collection tank and the rainwater bucket are rolled with white iron and lined with a rubber layer to prevent excessive noise when it rains;

The rainwater bucket is in the shape of an inverted square, and the cross section of the strip collection tank is an inverted trapezoid, with a large upper mouth and a smaller bottom.

Claims (1)

1. A roof rainwater collector, which collects and stores roof rainwater in a rainwater tank, and then takes it from it at any time. Its characteristics are: (1) Install a fixed rainwater collection tank along the direction of the wall directly under the eaves outside the house wall, and make the bottom of the tank have a certain slope along the direction of the wall to facilitate the flow of rainwater in the rainwater collection tank; (2) A rainwater bucket is installed at the lower end of the rainwater collection tank to connect with it, so that the rainwater in the rainwater collection tank is gathered in the rainwater bucket; (3) Cover and fix the grid on the notch of the rainwater collection tank and the top of the rainwater bucket to prevent plant stems, leaves and weeds from falling into the rainwater collection tank and rainwater bucket; (4) Install and fix a standpipe on the wall so that the upper end is connected with the rainwater bucket and the lower end is connected with the rainwater tank.
