An energy-saving and environment-friendly concealed control fire hydrant

Abstract

The invention relates to the technical field of energy conservation and environmental protection, and discloses an energy-saving environment-friendly concealed regulating fire hydrant. The energy-saving environment-friendly concealed regulating fire hydrant comprises a concealed tank, wherein a water inlet pipe is fixedly connected to the surface of the concealed tank; a water storage tank is fixedly connected to the interior of the concealed tank; a pressurizing pipe is movably connected to the interior of the water storage tank; a return spring sleeves the surface of the pressurizing pipe; apiston is movably connected to one end, away from the pressurizing pipe, of the return spring; and a piston rod is fixedly connected to one end, away from the return spring, of the piston. Accordingto the energy-saving environment-friendly concealed regulating fire hydrant, a retaining block on the surface of the piston rod can move upwards along with the piston rod; when the retaining block isin contact with a push plate, the retaining block can push the push plate to slide upwards on the surface of a sliding rail to make a connecting port gradually extends out of the ground surface; whenthe retaining block is in contact with the push plate, the piston does not move any more, the water pressure in the water storage tank increases, then water flows into a drain pipe in the piston fromthe pressurizing pipe, and a connecting port is lifted to complete discharging, so that the effect of guaranteeing the water supply pressure while reducing the valve opening pressure is achieved.

Description

technical field [0001] The invention relates to the technical field of energy saving and environmental protection, in particular to an energy saving and environmental protection hidden control fire hydrant. 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 fire. [0003] Traditional outdoor fire hydrants are generally installed on the edge of the road. During the driving process of pedestrians and vehicles, it is easy to scratch the fire hydrant, especially at night when the lighting conditions are not good, it is easy to cause damage to personnel, vehicles and fire hydrants.

Problems solved by technology

[0003] Traditional outdoor fire hydrants are generally set on the edge of the road. During the driving process of pedestrians and vehicles, it is easy to scratch the fire hydrant, especially at night when the lighting conditions are not good, it is easy to cause damage to personnel, vehicles and fire hydrants.

[0004] In addition, when encountering a fire, firefighters need to unscrew the valve. The huge water pressure will not only cause the valve to open for a long time, which will seriously affect the progress and timeliness of fire extinguishing, but also cause a large amount of tap water to be lost during the fire extinguishing process. After the fire extinguishing work is completed, on the one hand, too much water near the fire hydrant will affect the normal passage of pedestrians, on the other hand, it will also cause tap water to accumulate in the fire hydrant body, which is prone to freezing and freezing in winter, and even freezes the fire hydrant The main body causes material loss and waste of water resources, so an energy-saving and environmentally friendly hidden control fire hydrant came into being
