Telescopic hidden fire hydrant based on Bernoulli principle

Abstract

The invention discloses a telescopic hidden fire hydrant based on the Bernoulli principle. The telescopic hidden fire hydrant comprises a shell, and an opening and closing mechanism, a high-pressure pipe network and a telescopic water outlet mechanism are arranged in the shell; the shell comprises a main shell body, an upper shell body and a closed shell body; the main shell body, the upper shellbody and the closed shell body are matched to form a cavity for containing the fire hydrant; the telescopic water outlet mechanism is used for providing a water source for fire fighting equipment, andis arranged to be switched between a stretching water outlet state and a retracted water stopping state; the opening and closing mechanism is used for controlling the telescopic water outlet mechanism to be switched between the stretching state and the retracted state, and is arranged to be switched between an open state and a closed state; the high-pressure pipe network is arranged between the opening and closing mechanism and the telescopic water outlet mechanism, one end of the high-pressure pipe network is connected with the opening and closing mechanism, and the other end of the high-pressure pipe network is connected with the telescopic water outlet mechanism; the high-pressure pipe network is used for introducing water flow and controlling the telescopic water outlet mechanism through the opening and closing mechanism.

Description

technical field [0001] The invention relates to a fire fighting equipment, in particular to 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 technical purpose, the technical schem...
