Embodiment Construction

[0024] See attached picture. The automatic antifreeze device described in this embodiment includes a tubular main body 1, the radial section of the tubular main body is a rectangular structure, the two ends of the tubular main body are respectively a water inlet 2 and a water outlet 3, and the radial sections of the water inlet and water outlet are circular. Shaped structure, the diameters of the water inlet end and the water outlet end are smaller than the width of the tubular main body. A drain hole 4 is provided below the tubular main body 1, and a mounting seat 5 is provided on the side of the drain hole 4. A rotating shaft 6 is arranged on the mounting seat 5, and a cover plate 7 and a water retaining plate 8 are fixed on the rotating shaft 6. The cover plate 7 Located above the drain hole 4, the cover plate 7 and the water retaining plate 8 are perpendicular to each other, and the water retaining plate is close to the side of the water inlet; the cover plate 7 and the wa...

Abstract

The invention discloses an automatic anti-freezing device of an outdoor fire hydrant and a using method thereof. The automatic anti-freezing device comprises a tubular main body, wherein a water drainage hole is formed in the lower portion of the tubular main body, a mounting base is further arranged in the tubular main body, a rotating shaft is rotationally installed on the mounting base, a cover plate and a water baffle are fixed on the rotating shaft, the cover plate is located above the water drainage hole, and the cover plate is perpendicular to the water baffle; the cover plate and the water baffle rotate around the mounting base through the rotating shaft, and two states that the cover plate is tightly attached to the water drainage hole and the cover plate is separated from the water drainage hole exist; and the automatic anti-freezing device further comprises a bypass pipe, a water ejector is arranged on the bypass pipe, and a water suction pipe is arranged on the water ejector. According to the automatic anti-freezing device, a rotary spring is arranged on the rotating shaft, so that the cover plate is kept in an open state when the cover plate is not used, automatic water drainage is realized, water in a pipeline on a freezing line is discharged into a water collecting pit in a valve well, and the pipeline of the outdoor fire hydrant is prevented from being frozen in winter; and the water ejector can pump back accumulated water in the water collecting pit, and the accumulated water in the water collecting pit is automatically discharged.

Description

technical field [0001] The invention belongs to the technical field of fire hydrants, in particular to an automatic antifreeze device for an outdoor fire hydrant and a use method thereof. Background technique [0002] The outdoor fire hydrant is a water supply facility installed on the fire water supply pipe network outside the building. It is mainly used for fire trucks to take water from the municipal water supply pipe network or outdoor fire water supply pipe network to put out fires. One of the important fire facilities. Due to the low temperature in winter, the accumulated water in the cavity of the fire hydrant after use or testing will freeze and block and cannot be used, resulting in paralysis of fire water supply and serious loss of life and property. Therefore, the antifreeze work of fire hydrants is particularly important. [0003] At present, there are mainly two types of outdoor fire hydrants in my country, direct installation on the ground and underground wel...
