Fire hose configuration method for mountain fire fire extinguishing platform of transmission line

Abstract

The invention discloses a fire hose configuration method for a mountain fire fire extinguishing platform of a power transmission line, which comprises acquiring the characteristic information of the fire hose and the fire extinguishing water agent and the optimal atomization pressure of the structure of the fire extinguishing sprinkler head of the power transmission line; and calculating the fire extinguishing water agent Pressure loss along the way; calculate the local pressure loss of the fire extinguishing agent; calculate the pressure inlet of the atomizing nozzle of the mobile fire extinguishing platform; combine the pressure loss and the optimal atomization pressure of the nozzle to calculate the theoretical configuration length of the fire hose; correct the configuration of the fire hose length, to get the best fire hose length for the transmission line mountain fire fire extinguishing platform. The invention combines equipment parameters to calculate pressure loss and local loss along the process, configures the length of the hose according to the atomization characteristics of the nozzle, can ensure that the fire extinguishing platform works in the best atomization state for fire extinguishing, and ensures the safety and efficiency of fire extinguishing; The fire hose configuration correction for the spatial layout of the fire extinguishing platform improves the space utilization of the fire extinguishing platform and optimizes the fire extinguishing method of the transmission line mountain fire.

Description

technical field [0001] The invention specifically relates to a method for arranging fire hoses on a power transmission line mountain fire fire extinguishing platform. Background technique [0002] With the development of economy and technology and the improvement of people's living standards, electric energy has become an indispensable and most important secondary energy source in people's production and life. As a medium for transmitting electric energy to end users, the safe operation of transmission lines is very important. [0003] At present, in rural areas, liquefied petroleum gas and coal gas have gradually replaced wood as the main fuel, and barren hills and wastelands are gradually covered by dense vegetation, and the vegetation near transmission line corridors is becoming denser and denser. Behaviors such as the Spring Festival, Qingming ancestor worship and extreme dry weather can easily trigger large-scale wildfires, which not only threaten the ecological enviro...

Problems solved by technology

Limited by the working performance of the water pump, the maximum pressure of the fire extinguishing platform will also be limited. When extinguishing a wild fire on a transmission line in the field, the area where the mountain fire occurs may exceed the lift or delivery distance of the mobile fire extinguishing platform; The pressure loss in the belt is too large, and the pressure at the end of the fire hose fails to reach the atomization pressure of the water gun, resulting in the inability to deal with the mountain fire in time and threatening the safety of firefighters

[0006] However, the water delivery distance test of the fire extinguishing platform is difficult, mainly because it is difficult to find a suitable field place for the test, and the test requires a lot of manpower and material resources

The fire hose of the fire extinguishing platform is several thousand meters long, with many joints, complex terrain on site, and local loss is difficult to determine, which may lead to excessive water pressure loss along the way and poor fire extinguishing effect
