Problems solved by technology

[0002] While fire brings convenience to human beings, it also brings great disasters to human beings. Fire hydrant is a necessary fire-fighting facility in a city, which marks the development speed of a city. Fire-fighting facilities in cities are generally located above the ground, and often Crashed or even crashed by passing vehicles, the damaged fire hydrant will discharge a large amount of water, which not only affects urban traffic and urban beautification, but also wastes water resources. fire rescue, which poses a huge threat to the safety of people's lives and property

Embodiment Construction

[0058] Such as Figure 3-4 As shown, the self-retractable hidden fire hydrant installed on municipal roads or building floors includes a fire hydrant buried below the ground and can be switched between automatically extending above the ground and automatically retracting below the ground to provide firefighters with The fire hydrant body 300 of the water source, the first valve 100 set between the fire hydrant body 300 and the urban water supply pipe for controlling the switching of the fire hydrant body 300 between the extended state and the contracted state, and the opening and closing device sleeved outside the fire hydrant body 300 The opening and closing mechanism 400 can receive the drive of the fire hydrant body 300 to switch between the open state and the closed state. The fire hydrant body 300 is in a contracted state and is located below the ground in the non-working state. The first valve 100 and the fire hydrant body 300 can automatically extend above the ground an...

Abstract

The invention discloses a fire hydrant contraction concealing and self-stretching high-pressure water jet method. The method includes steps: in a stretching stage, a first valve is turned on to allowwater to flow into a transition cavity, and water flow contacts with a positioning conduction mechanism and pushes a second firefighting vertical pipe to move along the center axis of a first firefighting vertical pipe from a water inlet end of the first firefighting vertical pipe to a water outlet end of the first firefighting vertical pipe; in a transition stage, a second valve is turned off, the second firefighting vertical pipe stops discharging water but is still in the stretching stage; in a contraction stage, the first valve completes transition and is in a closed state, water flows into a storage cavity, water flow contacts with the positioning conduction mechanism and pushes the second firefighting vertical pipe to move along the center axis of the first firefighting vertical pipefrom the water outlet end of the first firefighting vertical pipe to the water inlet end of the first firefighting vertical pipe, the positioning conduction mechanism is separated from a limiting mechanism, a trigger rod is separated from an inner limiting step, a second valve core moves upwards under the elastic force of a first spring, and a first drainage hole is sealed by the second valve core.

Description

technical field [0001] The invention relates to a fire rescue method, in particular to a high-pressure water spraying method of a fire hydrant. Background technique [0002] While fire brings convenience to human beings, it also brings great disasters to human beings. Fire hydrant is a necessary fire-fighting facility in a city, which marks the development speed of a city. Fire-fighting facilities in cities are generally located above the ground, and often Crashed or even crashed by passing vehicles, the damaged fire hydrant will discharge a large amount of water, which not only affects urban traffic and urban beautification, but also wastes water resources. Fire rescue has brought huge threat to people's life and property safety. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a retractable fire hydrant installed below the ground. [0004] In order to realize the above-mentioned te...
