Problems solved by technology

But there is still no water (or foam fire extinguishing agent) and the fire gun that the superfine dry powder fire extinguishing agent mixes and sprays at home and abroad, especially be used for spraying water (or foam fire extinguishing agent) and spraying water (or foam fire extinguishing agent) on the high-rise fire fighting vehicle that is used for high-rise building fire fighting. The fire monitor with mixed jet of ultra-fine dry powder fire extinguishing agent is still blank
A large number of troops are invested in fighting a fire in a building, the duration of the fire fighting battle is long, and the consumption of fire extinguishing agent is large

Embodiment 1

[0033] see figure 1 , figure 2 When using the multifunctional fire monitor provided by the present invention to extinguish a high-rise building fire, the multifunctional fire monitor of the present invention is raised to the corresponding height for extinguishing the fire floor with the elevating jet fire truck, and then the control box 1 is operated to switch on the rotation control The circuit of the motor 5 controls the horizontal rotation mechanism assembly 3 and the vertical rotation mechanism assembly 4 to make the fire monitor rotate horizontally or pitch, aim at the window of the fire room, and manipulate the water supply system of the fire truck so that the pressure is 0.8-1.2Mpa and the flow rate is 0.8-1.2Mpa. The water or foam fire extinguishing agent of 40-60L / s is input into the fire monitor through the installation seat 2, and enters the nozzle 7 through the horizontal rotation mechanism component 3, the vertical rotation mechanism component 4 and the water del...

Embodiment 2

[0035] see figure 1 , figure 2 When adopting the multifunctional fire monitor provided by the present invention to extinguish a large fire in a limited space where water is not suitable for extinguishing a fire, first extend the extension arm on the elevated jet fire truck, point to the opened window or other passages, manipulate the control box 1, and then Through the circuit of the rotation control motor 5, the horizontal rotation mechanism assembly 3 and the vertical rotation mechanism assembly 4 are manipulated, so that the fire monitor performs horizontal rotation or pitching motion to align with the opened window or other channels, and controls the powder supply of the superfine dry powder fire extinguishing agent of the fire truck System, driven by compressed nitrogen at a pressure of 1.2-1.6Mpa, the ultra-fine dry powder fire extinguishing agent with a flow rate of 8-12kg / s is input into the powder inlet pipe 72 of the fire monitor, and the dry powder fire extinguishi...

Embodiment 3

[0037] see figure 1 , figure 2 When using the multifunctional fire monitor provided by the present invention to spray water or foam fire extinguishing agent, the water supply system of the fire truck is manipulated so that the water or foam fire extinguishing agent with a pressure of 0.8-1.2Mpa and a flow rate of 60-100L / s passes through the mounting seat 2 Enter the fire monitor, enter the nozzle 7 through the horizontal rotation mechanism assembly 3, the vertical rotation mechanism assembly 4 and the water delivery elbow 8, and the water or foam fire extinguishing agent is sprayed from the ring formed by the water inlet pipe 71 and the dry powder fire extinguishing agent injection pipe 74 Passage outlet injects in the current collector 73, and after being subjected to the reflection of current collector 73 inner surfaces, jet flow is ejected from the nozzle with the conical shape of constriction, aggregates into columnar water or Foam fire extinguishing agent jet, manipula...

Abstract

The invention discloses a multi-functional fire-fighting monitor and application thereof. The multi-functional fire-fighting monitor comprises a control cabinet, a mounting base, a horizontal rotating component, a vertical rotating component and a fire-fighting monitor head, wherein the horizontal rotating component is arranged on the mounting base and is sequentially communicated with the vertical rotating component and the fire-fighting monitor head by a water delivery elbow pipe, rotating control motors are arranged on the horizontal rotating component and the vertical rotating component respectively, the control cabinet is electrically connected with the rotating control motors on the horizontal rotating component and the vertical rotating component, and the fire-fighting monitor head comprises a water inlet pipe, a powder inlet pipe, a flow collector, a dry powder extinguishing agent injection pipe and a telescopic motor. The multi-functional fire-fighting monitor can singly jet water, a foamed extinguishing agent or a superfine dry powder extinguishing agent, and can jet mixture of the water or the foamed extinguishing agent and the superfine dry powder extinguishing agent, can be used in various fire behaviors, greatly improves the fire extinguishing efficiency and has a remarkable practical value.

Description

technical field [0001] The invention relates to a multifunctional fire monitor and its application, belonging to the technical field of fire fighting equipment. Background technique [0002] The total number of high-rise buildings in my country's cities is growing rapidly. Statistics show that by 2008 there were 9,816 high-rise buildings in Shanghai, 8,592 in Beijing, 8,664 in Chongqing, and 7,502 in Guangzhou. After a fire breaks out in a high-rise building, the fire spreads rapidly under the action of the "chimney effect", and high-temperature toxic smoke spreads. It is very difficult to evacuate personnel, firefighters climb, and transport fire extinguishing agents during fire fighting. Fire fighting in high-rise buildings is a worldwide problem. [0003] According to the relevant fire rescue equipment construction plan issued by the Ministry of Public Security: within the past three years, the fire brigade will be equipped with multi-dose combined elevating jet fire tr...
