Environment-friendly and energy-saving building water supply and drainage system

Abstract

The invention relates to an environment-friendly and energy-saving building water supply and drainage system. The system comprises a house body, an inclined roof is arranged at the top of the house body, a water collecting tank is arranged at the inclined bottom end of the roof, a filter screen is fixedly arranged on the upper surface of the water collecting tank, the bottom end of the water collecting tank communicates with a water diversion pipe, and a cleaning assembly for cleaning the surface of the filter screen is arranged on the roof surface; the cleaning assembly comprises a mounting plate, a cleaning plate and a cleaning needle, the cleaning plate is located on the side, facing the filter screen, of the mounting plate, a first elastic piece is fixedly connected between the side, deviating from the cleaning plate, of the mounting plate and the roof, and the cleaning needle is fixed to the mounting plate and penetrates through the cleaning plate in the roof inclination direction; and a second elastic piece is fixedly connected between the cleaning plate and the mounting plate, the elastic force of the second elastic piece is larger than that of the first elastic piece, and apull rope is fixedly connected to the side, deviating from the mounting plate, of the cleaning plate and extends downwards along the house body. The system has the effect of improving the cleaning convenience of the filter screen.

Description

technical field [0001] This application relates to the field of building construction, in particular to an environment-friendly and energy-saving building water supply and drainage system. Background technique [0002] Water supply and drainage is the abbreviation of water supply and drainage science and engineering. It generally refers to the urban water supply system / drainage system. Water supply and drainage is a scientific means of recycling water, so as to maximize the use of water resources and have the advantages of energy saving and environmental protection.

Problems solved by technology

[0003] Water supply and drainage settings are required in building houses. The water supply and drainage of the roof of the house can collect and reuse rainwater. In related technologies, the water supply and drainage of houses involves the collection and reuse of rainwater, and the rainwater is simply exported to the floor through pipes. Then it flows into the municipal pipe network, but the rainwater needs to be filtered when it is filtered during the collection process. Generally, a filter is installed at the collection port on the top of the house to filter, but after a long time of use, the surface of the filter is easy to accumulate fallen leaves. If solid impurities cause blockage, rainwater cannot be collected effectively, resulting in waste. However, the filter screen is installed on the top of the house. After the blockage, it is necessary to manually climb up to the roof for cleaning operations.

[0004] In view of the above-mentioned related technologies, the inventor believes that there is a defect that it is difficult to clean up after the filter screen is clogged
