Description

Intelligent anti-collision fire hydrant

Technical Field

The utility model discloses a belong to fire-fighting equipment technical field, specifically be an intelligence anticollision fire hydrant.

Background

A fire hydrant is an important tool for guaranteeing fire extinguishment of fire-fighting troops, mainly has the functions of controlling combustible substances, isolating combustion-supporting substances and eliminating ignition sources, and is divided into an indoor fire hydrant and an outdoor fire hydrant. The outdoor fire hydrant is a water supply facility arranged on a fire-fighting water supply pipe network outside a building, is mainly used for a fire truck to take water from a municipal water supply pipe network or an outdoor fire-fighting water supply pipe network to put out a fire, and can also be directly connected with a water hose and a water gun to discharge water to put out a fire. Some fire extinguishing and fire fighting vehicles have limited water carrying capacity, and need to find water sources during fire extinguishing. At this time, the hydrant performs a great water supply function.

The fire hydrant body part is directly exposed above the road surface, and in the actual management process, the fire hydrant often breaks because of vehicle impact, and because the fire hydrant is the direct connection water supply pipe network, after the fire hydrant breaks, can cause the pipe network water to leak in a large number, causes the road surface to be flooded, a large amount of losses of pipe network water.

The fire hydrant is mainly used for extinguishing fire and taking water, so how to quickly find the fire hydrant as a fire hydrant using department, the water taking is quick and convenient, and the desire and the requirement of a fire department are easy. However, in real life, a large amount of water is usually used for car washing, greening, environmental sanitation, construction in construction sites and the like, water is often wasted, some fire hydrants seriously threaten the smooth development of fire extinguishing work because of poor management and even water supply interruption, and once a fire disaster occurs, the fire hydrants cannot play the due role. Its shortage and damage pose a serious threat to the life and property safety of people.

The fire hydrant is used as one of auxiliary facilities of the pipe network, the maintenance management of the fire hydrant requires that a special management team is established, the special management is carried out, and once the failure of the fire hydrant is found, the failure of the fire hydrant is treated as the explosion of the pipe network in time. Besides, a periodic maintenance schedule for the fire hydrant should be planned, and regular maintenance measures should be implemented. However, the existing outdoor fire hydrant has more quantity, needs a large amount of manpower for real-time supervision, is inconvenient to supervise and has high patrol cost. The method needs to improve the management means of fire hydrant and effectively master the distribution of the fire hydrant and the problem of 'failure of the fire hydrant'.

With the development of the internet of things technology, a common fire hydrant is developed into an intelligent fire hydrant through a wireless network, a sensor technology and a data analysis technology, the state of the fire hydrant and a fire hydrant water source are remotely and dynamically monitored and managed, and the intelligent fire hydrant system is an important way for solving the problem of fire hydrant management.
