Description

Technical Field

[0001] The present invention relates to the technical field of forest fire fighting skill training, and in particular to a forest fire fighting skill and tactical training system. Background Art

[0002] Forest firefighting tactics are the product of a certain historical stage in the development of forest fire prevention and firefighting technology in my country. They gradually emerged with the advent of forest fire fighting and have continued to evolve in the course of firefighting practice. Currently, forest fire fighting in my country primarily relies on direct human action. Fighters typically work in squads (or groups), operating various firefighting equipment according to their assigned tasks, and working collaboratively to complete forest firefighting tasks. However, due to the high risk nature of forest firefighting, direct contact between personnel and fire can result in casualties if careless.

[0003] Currently, forest fire brigades conduct team-based firefighting technique and tactical training primarily on drill fields. These training subjects are based on existing armed police tactics, incorporating practical developments in forest fire fighting to develop seven basic team (group) firefighting tactics. However, drill fields cannot reflect the actual fire scene environment, requiring simulated forest fire scenarios for training. This lacks intuitiveness and compromises training effectiveness. Furthermore, the fire scene environment is highly uncertain due to factors such as topography, vegetation, and weather, leading to variations in firefighting tactics each time. Drill field training, on the other hand, emphasizes standardized procedures and uniform movements, using a single simulated scenario, which compromises training effectiveness. Regularly conducting live fire training requires cumbersome preparation, is time-consuming, and labor-intensive, and the results of each fire are inconsistent, making training incomparable and posing safety risks. Summary of the Invention

[0004] In response to the problems existing in the prior art, the purpose of the present invention is to provide a forest fire fighting technique and tactics training system, which is aimed at addressing the problems in the existing technology.

[0092] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0093] like Figure 1-Figure 24 The forest fire fighting technique and tactics training system shown includes a steep slope climbing tactical training device 1, a fire chasing and extinguishing tactical training device 2, a fire scene encirclement tactical training device 3, a fire line rushing tactical training device 4, a fire blocking and extinguishing tactical training device 5, a fire scene clearing tactical training device 6, a fire extinguishing bomb throwing tactical training device 7, as well as a gas system for supplying gas, a smoke system for supplying smoke, and a control system for controlling the flow of gas and smoke.

[0094] The gas system includes a gas source 8-3 and gas pipelines. The gas pipelines include a gas main 8-1 connected to the gas source 8-3, a first gas branch 8-21, a second gas branch 8-22, a third gas branch 8-23, a fourth gas branch 8-24, a fifth gas branch 8-25, a sixth gas branch 8-26, a seventh gas branch 8-27, and other pipelines connecting these gas branches to the gas main 8-1. The gas source 8-3 can be a liquefied gas cylinder or a municipal gas pipeline.

[0095] The smoke system includes a smoke-making device 9-3 and a smoke pipe; the smoke pipe includes a smoke main pipe 9-1 with smoke-making devices 9-3 at both ends, a first smoke branch pipe 9-21, a second smoke branch pipe 9-22, a third smoke branch pipe 9-23, a fourth smoke branch pipe 9-24, a fifth smoke branch pipe 9-25, a sixth smoke branch pipe 9-26 and other pipes for connecting the above-mentioned smoke branch pipes with the smoke main pipe 9-1.

[0097] In this example, the forest firefighting tactics training system of the present invention includes tactical training devices for seven basic squad (group) tactical training exercises. These devices simulate environments where different tactics are applied, resolving the existing issue of a single training environment while also improving training effectiveness. A control system controls the gas and smoke systems, activating and applying the corresponding tactical training devices for tactical training. This avoids the impact of most inclement weather conditions and facilitates training. During training, the seven tactical training devices can be freely combined to conduct tactical training, improving participants' tactical proficiency.

[0098] like Figure 1-Figure 5 As shown, the steep slope tactical training device 1 includes a steep slope body 1-1. A first slope 1-11 is provided at one end of the steep slope body 1-1, and a second slope 1-12 is provided at the other end. The first slope 1-11 is steep, and its gradient is greater than that of the second slope 1-12. Preferably, the steep slope is further provided with a third slope 1-13 at the end provided with the first slope 1-11. The third slope 1-13 is also steep, and its gradient is less than that of the first slope 1-11, but greater than that of the second slope 1-12. Simulation layers are provided on the slopes at both ends of the steep slope body 1-1 to simulate common obstacles. These simulation layers include various types of layers for simulating cliff weeds, tree roots and vines, and dirt roads.

[0099] A platform is provided on the top of the steep slope main body 1-1, and guardrails 1-2 are provided on both sides of the steep slope main body 1-1. The bottom of the guardrails 1-2 is fixedly connected to the embedded steel plate pre-fixed on the steep slope main body 1-1; an obstacle net 1-3 is provided above the second slope 1-12, and a number of obstacle ropes are provided on the obstacle net 1-3 that naturally droop due to gravity.

[0100] The fourth smoke branch pipe 9-24 is connected to the steep slope main body 1-1 and is provided with a smoke outlet on at least one slope. Preferably, there are two fourth smoke branch pipes 9-24, with the smoke outlets of the fourth smoke branch pipes 9-24 being located on the second slope 1-12. The pipe connecting the fourth smoke branch pipe 9-24 and the main smoke pipe 9-1 is provided with a smoke on / off valve 10-21 and a fan 10-22. The smoke on / off valve 10-21 and the fan 10-22 are electrically connected to the main controller.

[0101] Training process: The control system controls the smoke-making device 9-3 to make smoke, and makes the smoke be emitted from the smoke outlet of the fourth smoke branch pipe 9-24; the trainees go uphill from the end of the steep slope main body 1-1 where the first slope 1-11 is provided, and go downhill from the end where the second slope 1-12 is provided; pay attention to avoid the obstacle rope during the downhill process.

[0102] In this example, the slopes at both ends of the steep slope body 1-1 can be set according to training needs. The setting content includes the number of additional slopes and the control of the slope gradient. The slope gradient on the side where the first slope 1-11 is located is between 45° and 60°. Preferably, the slope of the first slope 1-11 is set to 60°, the slope of the third slope 1-13 is set to 45°, and the slope of the side where the second slope 1-12 is located is between 25° and 35°. Preferably, the slope of the second slope 1-12 is 30°. The setting of the guardrail 1-2 is used to protect the lives of the trainees. The setting of the obstacle net 1-3 and the obstacle rope is used to increase the difficulty of training and improve the training effect.

[0103] like Figure 1 、 Figure 6 、 Figure 7 and Figure 8 As shown, the fire-chasing tactical training device 2 includes a first gas fire trough 2-1 and a first real fire trough 2-2. The first gas fire trough 2-1 and the first real fire trough 2-2 have the same shape, each including a horizontally arranged arc segment and extension segments extending linearly outward at both ends of the arc segment. The first gas fire trough 2-1 and the first real fire trough 2-2 are longitudinally spaced apart.

[0104] Several first gas branch pipes 8-21 are connected to the first gas burner 2-1. Gas outlets are provided at the first gas burner 2-1. Flame pipes 8-4 are connected to the outlets to improve gas flow. Ignition devices 10-15 and wind pressure sensors 10-14 are located next to the flame pipes 8-4. A gas on / off valve 10-11 and a flow control valve 10-12 are installed on the first gas branch pipes 8-21. The pipeline connecting the first gas branch pipes 8-21 to the main gas pipe 8-1 is also equipped with a gas on / off valve 10-11 and a gas alarm 10-13. The gas on / off valve 10-11, flow control valve 10-12, gas alarm 10-13, ignition device 10-15, and wind pressure transmitter are electrically connected to the main controller. The wind pressure transmitter transmits information from the wind pressure sensor 10-14 to the main controller.

[0105] The gas switch valve 10-11 and the flow control valve 10-12 provided on the first gas branch pipe 8-21 can be used to control the gas passing through the first gas branch pipe 8-21, thereby enabling the gas entering the first gas fire tank 2-1 to be adjusted in sections, and controlling whether the gas is input and the size of the input gas flow rate.

[0106] The first smoke branch pipe 9-21 is connected to the first gas burner 2-1 and is provided with a smoke outlet at the first gas burner 2-1. A pressure sensor 10-23 is located next to the smoke outlet. A smoke on / off valve 10-21 is installed on the first smoke branch pipe 9-21. The pipe connecting the first smoke branch pipe 9-21 to the main smoke pipe 9-1 is also equipped with a smoke on / off valve 10-21 and a fan 10-22. The smoke generating device 9-3, smoke on / off valve 10-21, fan 10-22, and pressure transmitter are electrically connected to the main controller. The pressure transmitter transmits information from the pressure sensor 10-23 to the main controller. The smoke on / off valve 10-21 and fan 10-22 on the first smoke branch pipe 9-21 control the flow of gas through the first smoke branch pipe 9-21, thereby enabling segmented regulation of the gas flow into the first gas burner 2-1 and controlling the presence and flow of smoke.

[0107] The fifth gas branch pipe 8-25 is connected to the first live flame tank 2-2 and is provided with an outlet there. A flamethrower 8-4 is connected to the outlet to improve gas flow. An ignition device 10-15 is located next to the flamethrower 8-4. A gas on / off valve 10-11 is installed on the fifth gas branch pipe 8-25. The pipeline connecting the fifth gas branch pipe 8-25 to the main gas pipe 8-1 is also equipped with a gas on / off valve 10-11, a flow control valve 10-12, and a gas alarm 10-13. The gas on / off valve 10-11, flow control valve 10-12, gas alarm 10-13, and ignition device 10-15 are electrically connected to the main controller.

[0108] In this example, a simulated gas fire line and a simulated real fire line were constructed. The shapes of the first gas fire trough 2-1 and the first real fire trough 2-2 are designed to simulate the state of a real fire line. Based on the speed of a forest fire's spread, the fire line can be divided into the head, wings, and tail. The head is the area of ​​the fire that spreads downwind and is the primary location for fire development. It spreads quickly downwind, has high intensity, and is difficult to control, potentially causing casualties among firefighters. The tail is the area of ​​the fire that spreads upwind, has a slower spread and is easier to control. The wings are the areas of the fire that spread sideways, have an intermediate spread speed, and are also crucial for fire control. Therefore, when attacking a fire line, avoid the head and approach the fire line from the wings or tail, where the forest fire spreads relatively slowly. The head of a fire line spreads quickly, the wings spread slower than the head, and the tail has the slowest spread. An ideal fire line is curved. The curved segments are used to simulate the state of a fire line. However, in actual firefighting operations, the wind speed and direction at the fire scene are changeable, and the fire line has an irregular shape.

[0109] Gas fire simulation line: Gas source 8-3 is activated to supply gas to the gas pipeline. The control system controls the direction of gas flow, directing it from the outlet of the first gas branch pipe 8-21 into the first gas fire trough 2-1. The ignition device 10-15 ignites the gas, which then burns in the first gas fire trough 2-1. During the combustion process, the control system synchronously controls the smoke generator 9-3 to generate smoke, supplying it to the smoke pipeline and emitting it from the outlet of the first smoke branch pipe 9-21.

[0110] Real fire simulation fire line: combustible materials are set in the first real fire tank 2-2 in advance; the gas source 8-3 is started to supply gas to the gas pipeline; the gas flow direction is controlled by the control system so that the gas is discharged from the outlet of the fifth gas branch pipe 8-25 to the first real fire tank 2-2; the gas is ignited through the ignition device 10-15, and combustion is carried out using the combustible materials as fuel.

[0111] Training process: The gas fire simulation line and the real fire simulation line are started through the control system; the trainees work in shifts (groups) to extinguish the fire from the fire head or fire wing of the gas fire simulation line or the real fire simulation line; during the fire extinguishing process, the wind pressure sensor 10-14 and the pressure sensor 10-23 on the gas fire simulation line are started to control the segmented shutdown of the gas fire simulation line and the smoke shutoff.

A single spark can start a prairie fire. The fire line is the vanguard of fire spread, and the first priority in extinguishing a fire is to eliminate the fire line. The shape of the second gas fire trough 3-1 and the second live fire trough 3-2 simulates the conditions of the outer fire line of a fire scene.
