Abstract

The invention relates to the field of constructional engineering, in particular to an outdoor fire hydrant in a fire hydrant fire-extinguishing system. The outdoor fire hydrant is characterized in that a first flange disc is welded on a part which is a certain height away from the ground, on the outdoor fire hydrant; the height is necessary to meet the mounting requirement of the fire hydrant; a cylindrical protection device with a sealed top surface is sleeved outside the fire hydrant; a second flange disc is arranged on the lower part of the protection device; the first flange disc and the second flange disc are connected; a plurality of air holes are formed on a side wall of the protection device; a baffle is arranged on the height of the air holes and can block the air holes; and the baffle is arranged on a side wall of the protection device. According to the outdoor fire hydrant, the defects that the conventional outdoor fire hydrant is easily damaged, stolen and corroded, water resources are wasted, the service life of the fire hydrant is short and the like can be overcome.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a fire extinguishing device in an outdoor fire hydrant fire extinguishing system. Background technique [0002] "National Civil Building Engineering Design Technical Measures - Water Supply and Drainage" (2009 Edition) stipulates: "Outdoor fire hydrants should not be more than 2 meters away from the roadside, and should not be less than 5 meters away from the outer wall of the house." Based on this provision, some construction units place outdoor fire hydrants very close to the edge of the road during construction, and sometimes even close to the curb stone of the road. In this case, the front bolt cover and the left and right two bolt covers of the outdoor fire hydrant are extremely vulnerable to being damaged by the collision of other objects such as vehicles, so water dripping and leaking often occur at the cock mouth of the outdoor fire hydrant. [0003] The three bol...
