Description

Technical Field

[0001] This utility model relates to a smart fire hydrant. Background Technology

[0002] Fire hydrants are core equipment in fire protection systems used to provide water for firefighting. Existing fire hydrants consist of a hydrant body, a hydrant seat, and an inlet bend. The inlet bend connects to the fire water supply pipeline. These hydrants lack intelligence, relying solely on manual inspection and recording of water levels. They do not have an indicator function to show whether there is water in the hydrant seat. In emergencies requiring water supply to fire equipment, it is unclear whether water is available in the hydrant seat, impacting rescue time and efficiency. Improvements and optimizations are needed to address these issues. Utility Model Content
