Abstract

The invention relates to the technical field of fire-fighting equipment, and discloses an anti-theft fire hydrant, which includes a fire hydrant body. The inside of the fire hydrant body includes a shell, and an active cavity is opened inside the shell. The active cavity has a longitudinal section shape of Rectangular ring. The invention realizes the anti-theft effect through the sounding device, uses the difference of the water flow state inside the fire hydrant to trigger the movement of the mobile device, so that the vent hole of the generating device communicates with the outside air, and the air flow is disturbed by the splitter plate, so that the air flow is in the second The pipeline vibrates to generate sound, and then uses the difference between the sound signal when stealing water and the sound signal when extinguishing the fire to trigger the alarm device, and finally realizes the anti-theft effect, and reduces the occurrence of water theft through the alarm. The air duct, combined with the L-shaped duct, increases the air flow velocity inside the second duct, increases air vibration, and improves the capture effect of sound signals.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to an anti-theft fire hydrant. Background technique [0002] At present, most of the fire hydrants are installed on the ground close to the building area for the convenience of use. Due to the exposed location of these fire hydrants and their proximity to residential areas, some residents will steal the water inside the fire hydrants in order to save money. After the water is stolen from the fire hydrant, the fire hydrant will cut off the water when extinguishing the fire, which poses a safety hazard to the fire extinguishing effect at the fire scene. Contents of the invention [0003] Aiming at the deficiencies in the use of the existing fire hydrant proposed in the background technology, the present invention provides an anti-theft fire hydrant, which has the advantages of reducing the occurrence of fire hydrant water theft and automatic alarm, and solves the pro...
