Intelligent integrated rod of fire hydrant

The utility model discloses an intelligent integrated rod of a fire hydrant. The intelligent integrated rod comprises a valve rod, a liquid level detection device used for monitoring whether liquid exists in the fire hydrant or not and the liquid level, and pressure measuring equipment used for monitoring the hydraulic pressure in a fire-fighting pipe network communicated with the fire hydrant, the valve rod is provided with a height adjusting mechanism used for adjusting and controlling the vertical height of the valve rod according to the fire hydrant outer barrels of different models and sizes. According to the intelligent fire hydrant, performance parameter acquisition and communication transmission functions of liquid level detection and pressure measurement are integrated, intelligent networking control of mutually isolated and separated states of existing fire hydrants is realized, and the fire hydrant is controlled through the liquid level detection device and the pressure measurement equipment which
