A building roof siphon rainwater drainage system for energy recovery

Abstract

The invention relates to a building roof siphon type rainwater drainage system capable of achieving energy recovery. Currently, a building roof siphon type rainwater drainage system which is reasonable in structural design and capable of achieving energy recovery is not available. The building roof siphon type rainwater drainage system capable of achieving energy recovery is characterized by comprising a siphonic roof drain located in a center gutter, a hanging frame fixed to a floor slab below the center gutter, a rainwater connecting pipe, a hanger beam, a rainwater hanging pipe, hanging pipe clamps used for fixing the rainwater hanging pipe, a vertical rainwater pipe, horizontal pipe clamps, an output wire, a storage battery, an indoor rainwater inspection well and a hydro generator installed inside the indoor rainwater inspection well; the upper end of the rainwater connecting pipe is connected with the siphonic roof drain, and the lower end of the rainwater connecting pipe is connected with the hanging pipe clamps; the horizontal pipe clamps are fixed to the vertical rainwater pipe; the upper end of the vertical rainwater connecting pipe is connected with the rainwater hanging pipe; the lower end of the vertical rainwater pipe is located inside the indoor rainwater inspection well and matched with the hydro generator; the storage battery is connected with the hydro generator. According to the building roof siphon type rainwater drainage system capable of achieving energy recovery, the mechanical energy of rainwater is converted into electric energy, and the energy recovery efficiency is high.

Description

technical field [0001] The invention belongs to the field of rainwater resource regeneration and utilization, and relates to a rainwater drainage system for recovering rainwater energy, in particular to a building roof siphon rainwater drainage system for realizing energy recovery. Background technique [0002] In recent years, with the rapid development of the social economy, whether in the field of industrial production or in the civil field, large-scale public buildings such as multi-span factory buildings and complexes continue to emerge. In the above-mentioned architectural design process, the rainwater discharge of long-span roofs has increasingly become a hot spot of attention, mainly focusing on the rapid discharge of rainwater and the utilization of water resources. [0003] For the rapid discharge of rainwater, at present, the siphon rainwater drainage system can better solve the rainwater discharge on the roof under the condition of large catchment area. It is a p...

However, the siphon system has not yet been introduced into the roof rainwater power generation system

[0007] For the rainwater drainage system: the rainwater inspection well connected to the existing siphonic rainwater drainage system often needs to be equipped with special energy dissipation measures to offset the huge energy contained in the pressurized discharge pipe, which increases the civil construction cost of the drainage structure. Potential energy of rainwater cannot be effectively transformed and utilized
