Three-dimensional jet fire truck and its control method

Abstract

The invention discloses a three-dimensional jet fire truck and a control method thereof, relating to the field of fire trucks and used for realizing the reasonable distribution and high-efficiency utilization of the liquid supply flow rate of each fire gun in the three-dimensional jet mode. The three-dimensional jet fire truck includes an engine, a first fire monitor, a first liquid supply pipeline, a second fire monitor, a second liquid supply pipeline, a booster pump and a controller. The first liquid supply line is in fluid communication with the first fire monitor. When the second fire monitor is in the working state, the working height of the second fire monitor is higher than that of the first fire monitor, and the working height of the second fire monitor can be adjusted. The second liquid supply line is in fluid communication with the second fire monitor. The booster pump is in fluid communication with both the first liquid supply pipeline and the second liquid supply pipeline; the booster pump is driven and connected with the engine to supply the first liquid supply pipeline and the second liquid supply pipeline under the drive of the engine. Extinguishing agent. The engine acceleration control device is configured to control the flow of the first and / or second liquid supply line by adjusting the rotational speed of the engine.

Description

technical field [0001] The invention relates to the field of fire trucks, in particular to a three-dimensional jet fire truck and a control method thereof. Background technique [0002] As we all know, if a fire truck has only one fire monitor configuration, or although it has multiple fire monitors, it cannot be sprayed at the same time, so it is often difficult for a fire truck to form a fast and effective containment for multi-point fires and large fire disasters. , will inevitably delay the fire extinguishing process. [0003] In the actual fire extinguishing operation, multiple fire trucks can reach the scene, but it is often difficult to fully arrange multiple fire trucks in a limited space due to the influence of buildings and terrain near the fire site to realize the common use of multiple fire monitors. Spray to form a high-intensity fire extinguishing agent supply to fire extinguishing operations. Moreover, when faced with a large-scale fire scene, even if the sp...

Problems solved by technology

[0008] The third category is that the fire extinguishing agent supply system of each fire monitor shares a booster pump and a small part of the delivery pipeline, but the installation height and position of each fire monitor are greatly different, or the pipeline pressure loss of the liquid supply pipeline during the spraying operation The difference is large (note: each fire monitor is under the injection condition of its own rated flow rate), or there is a large difference in the inlet pressure required by each fire monitor to reach the rated flow rate

[0009] The inventors have found that among the above three types of three-dimensional jet fire trucks, the three-dimensional jet control methods of the first and second types of multi-cannon fire trucks are relatively simple and easy, but the first type of fire-fighting system has complex pipelines and complex system composition. The disadvantage of high cost is that it is mostly used in fire monitor injection systems of different types of fire extinguishing agents, such as dry powder injection and water cannon combined operations, and is rarely used in multi-cannon systems of the same type of fire extinguishing agents

The second type of three-dimensional jet fire trucks are basically installed at the same height, so the three-dimensional jet effect is obviously worse than that of the third type of three-dimensional jet fire trucks

[0010] Further, the inventor also found that there are at least the following problems in the prior art: if the third type of three-dimensional jet fire truck wants to achieve good three-dimensional jet performance, it is urgent to solve a difficult bottleneck problem, that is, in multiple When the guns work at the same time, how to solve the problem of reasonable matching of the pressure and flow of multiple fire monitors in a fire extinguishing agent delivery system that shares a booster pump

At present, the third type of three-dimensional jet fire truck, in the actual operation, either the pressure and flow are overloaded, or the pump supply flow is insufficient, and the multi-cannon jets are mutually restrained. The jet state is unstable, causing delays in fighting the fire
