Description

Technical Field

[0001] The utility model relates to the technical field of fire hydrant monitoring equipment, in particular to a fire hydrant intelligent monitoring equipment. Background Art

[0002] An outdoor fire hydrant is a common fire-fighting equipment, generally including a fire hydrant housing with a valve core. A locking cover is installed at the top opening of the fire hydrant housing. A threaded hole is provided on the locking cover. A threaded operating rod is installed in the threaded hole. The lower end of the operating rod is connected to the valve core through a connector. Its working principle is as follows: in the default state, the valve core and the valve body of the fire hydrant housing are tightly matched to achieve sealing. After the operating rod is turned so that the operating rod moves upward in the vertical direction, a gap is formed between the valve core and the valve body of the fire hydrant housing, so that the water in the fire-fighting pipe flows out from the gap and flows out through the water outlet provided on the side of the fire hydrant housing. Therefore, the traditional outdoor fire hydrant is a purely mechanical structure and does not have the functions of flow measurement, pressure measurement, temperature measurement, push alarm, empty pipe alarm, water use alarm, position movement and positioning.
