Transformer substation roof rainwater recycling system and control method

Abstract

The invention discloses a transformer substation roof rainwater recycling system. The transformer substation roof rainwater recycling system comprises a rainwater well, a water purification well and adownpipe. The rainwater well and the water purification well are arranged underground respectively, the top end of the downpipe is installed on a transformer substation roof, the downpipe is used forcollecting rainwater on the transformer substation roof, the bottom of the downpipe is communicated with the rainwater well, and the rainwater well and the water purification well are communicated through a connecting pipe. Multiple stages of water purification devices are arranged in the rainwater well and the water purification well and used for filtering the rainwater. A water quantity controldevice is arranged in the downpipe, and when the rainwater quantity is large, the downpipe and the rainwater well can be automatically disconnected. The system further comprises an automatic controldevice for monitoring and controlling the water quantities in the rainwater well and the water purification well. The rainwater on the transformer substation roof is collected, stored and filtered atmultiple stages, and therefore the problem about water utilization of an unattended transformer substation is solved.

Description

technical field [0001] The invention relates to a rainwater recovery and reuse system on the roof of a transformer substation, in particular to a novel rainwater recovery and reuse system suitable for the intermittent water use characteristics of an unattended transformer station. Background technique [0002] At this stage, unattended substations are generally built in areas far away from towns, and the surrounding area usually lacks municipal supporting facilities, and there is no municipal water supply, sewage, and rainwater pipe network. If the municipal water supply network is used, because it is far away from the urban area, it is necessary to set up a first-level, second-level or even third-level pressurized pump room and a pump room outside the station, which is inconvenient to manage and the cost is high. Depending on the situation, if the drilling is too deep, it may cause the foundation of the equipment to settle, and the cost of drilling is relatively high. In a...
