Abstract

The invention relates to the technical field of fire fighting equipment, and discloses an anti-theft fire hydrant which comprises a fire hydrant body, wherein a shell is arranged in the fire hydrant body, a movable cavity is formed in the shell, and the movable cavity is a circular ring with a rectangular longitudinal section. The anti-theft effect is achieved through a sound production device, a moving device is triggered to move by means of different water flow states in the fire hydrant, ventilation holes of the sound production device are made to communicate with outside air, airflow vibrates in a second pipeline under disturbance of a flow distribution plate so as to generate sound, the alarm device is triggered according to the difference between a sound signal during water stealing and a sound signal during fire extinguishing, the anti-theft effect is finally achieved, and the water stealing situation is reduced through alarming. Meanwhile, the ventilation pipeline is arranged on the second pipeline, the air flowing speed in the second pipeline is increased in cooperation with the L-shaped pipeline, air vibration is increased, and the sound signal capturing effect is improved.

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 set on the ground close to the building area for the convenience of use. These fire hydrants are exposed to the geographical location and close to the residential area, so some residents will steal the water source inside the hydrant for the sake of cheap. After the water is stolen from the fire hydrant, the water is cut off when the fire hydrant is put out, which poses a safety hazard to the fire extinguishing effect at the fire scene. SUMMARY OF THE INVENTION [0003] In view of the deficiencies in the use process of the existing fire hydrant proposed in the background art, the present invention provides an anti-theft fire hydrant, which has the advantages of reducing the occurrence of water theft by the fire hydrant and automatically alarming, and solves the pr...
