Blowout prevented fire hydrant, and fire fighting terminal providing flux information

Abstract

The spewing-preventing fire hydrant equips valve bolt and valve bolt rod. The lower part of the valve bolt rod links valve. Its characteristic is that the valve is spewing-preventing valve, comprising of hollowing-out valve seat and conic valve clack. On the valve clack there links valve clack rod on which equips spring. The valve clack rod is connected to the valve bolt through hemispherical joint. When the fire hydrant is impacted, the spigot body is separated at the surface of fracture. Because the hemispherical joints of the valve bolt rod and clack rod pole are separated, it can protect the underground spigot body. The often closed unidirectional valve is operated by any outer force, and the subulate valve petal and hollowing-out valve pedestal are operated by the spring force, they all form closed states, and can effectively prevent spewing. The optimized plan equips current capacity measurement device: on the valve clack rod there is measuring impeller on which fixed small magnet, and the corresponding place of the spigot body fixes magnetism sensor whose output is connected to the microprocessor. In the waterway there can be also equipped with valve state sensor, hydraulic pressure sensor and network communication interface, to structure fire hydrant current capacity measurement information terminal device and form network.

Description

technical field [0001] The present invention relates to a fire-fighting equipment, in particular to an anti-surge fire hydrant and a flow information fire-fighting terminal, including a fire hydrant anti-surge valve, a fire hydrant flow metering device, and an information fire hydrant terminal. : Information fire hydrant terminal. Background technique [0002] The fire hydrant is one of the indispensable infrastructures in modern cities. Its structure is: a valve bolt is arranged on the top of the hydrant body, and the water pipe valve located at the bottom of the hydrant body is connected through the valve bolt rod. The functions and appearance of fire hydrants have basically remained unchanged for decades, and it has been revealed in many aspects that they cannot meet the needs of modern urban construction. For example, with the rapid increase of urban motor vehicles and the unevenness of drivers' driving skills, incidents of fire hydrants being damaged by vehicles in var...

AI Technical Summary

Problems solved by technology

The fire hydrant was broken and the "spring" water gushed out, which not only damaged the fire-fighting facilities; it also caused a lot of waste of water sources, traffic blockage, and property losses caused by flooding of nearby shops and residents

The transition from the planned economy to a commodity economy has also brought new problems to the management of fire hydrants: traditional fire hydrants have no water flow metering devices, and there are no detection devices or communication devices for their various states. Turned into a commodity, the water intake and water consumption of fire brigades, urban greening teams and other units also have metering requirements, which cannot be realized by traditional fire hydrant structures

Another disadvantage of traditional fire hydrants is that many fire hydrants are in a state of water interruption or insufficient water pressure, which is difficult to find at ordinary times; it is not found that there is no water source until a fire breaks out, which delays precious firefighting time

After searching, there is no idea to connect this network field bus with anti-splash and flow metering information fire hydrant terminals.
