Rainwater and snowwater four-season storage system based on siphon principle

Abstract

The invention provides a rain and snow water four-season collecting and storage system based on a siphon principle, and belongs to the technical field of water supply and drainage. The system is characterized by comprising a siphon-type roof rain and snow water drainage system, a natural circulating type solar hot water snow melting system and a water storage and utilization system, wherein the natural circulating type solar hot water snow melting system is communicated with an inner sleeve in a roof water drainage pipeline through a three-way magnetic valve, hot water in an inner sleeved hot water pipeline is driven to circulate based on the thermo-siphon principle, circulating hot water enables snow water to be drained into an underground water storage tank under the action of solar energy, and the snow water can be used in daily life as collected rain water. The system has the advantages that roof rain water is drained through a eddy-proof rain water hopper, the anti-freezing problem of pipelines where the snow water in winter flows through is solved through the thermo-siphon solar energy heat collecting technique, the rain water and the snow water are purified and recycled underground, and accordingly the utilization rate of the rain water and the accumulated snow on a roof is improved.

Description

technical field

[0001] The invention belongs to the technical field of water supply and drainage, and relates to a siphonic roof rainwater and snowwater collection and storage system for four seasons, especially based on the advanced siphonic roof drainage system, combined with the thermosiphon principle and solar collectors, a snowwater and snowwater storage system is proposed. Antifreeze drainage storage system for common use of rainwater. Background technique

[0002] As a precious resource, rainwater and snowwater have been valued by countries all over the world. However, the buildings in our country are still dominated by the traditional gravity roof rainwater drainage system. There are problems such as large amount of horizontal pipes and branch pipes, high roof rainwater load, ineffective use of rainwater and roof snow, resulting in a large amount of water resources. Waste and waste of building space. The siphonic roof rainwater drainage system has been widely used ...
