Water-saving anticorrosion fire hydrant based on Bernoulli's principle

Abstract

The invention discloses a water-saving anticorrosion fire hydrant based on Bernoulli's principle, comprising a base arranged below the surface, an inflow valve arranged on the base, a water supply network, and a telescopic hydrant body; the inflow valve is used for controlling connection and disconnection between the telescopic hydrant body and an urban water supply pipeline; the water supply network is arranged between the inflow valve and the telescopic hydrant body and is used for conducting a high-pressure water flow; an opening-closing mechanism includes a mounting frame arranged on the base; an opening-closing component is arranged at the top of the mounting frame; a driving mechanism that drives the opening-closing component to switch between an opened state and a closed state is arranged between the base and the telescopic hydrant body; the driving mechanism is connected with the driving end of a first transmission mechanism, the output end of the first transmission mechanism is connected with the driving end of a second transmission mechanism; the output end of the second transmission mechanism is connected with the driving end of the opening-closing component, wherein when the inflow valve is in the opened state, connector II is communicated with connector III, and connector I is communicated with connector IV; when the inflow valve is in the closed state, the connector II is communicated with the connector IV, and the connector I is communicated with the connector III.

Description

[0001] This invention is a divisional application for an invention patent with an application date of November 25, 2017, an application number of 2017111982888, and an invention title of "self-telescopic concealed fire hydrant installed on municipal roads or building floors". technical field [0002] The invention relates to a fire fighting equipment, in particular to a fire hydrant. Background technique [0003] 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. Con...
