Description

Technical Field

[0001] This invention relates to the field of fire training technology, and in particular to a grassland fire simulation training system. Background Technology

[0002] Grassland areas are characterized by dense vegetation and open terrain, making them prone to fires that spread rapidly, affect a wide area, and are difficult to extinguish, posing a serious threat to people's lives and property and the ecological environment. Conducting efficient and realistic fire-fighting training is crucial to improving the emergency response and collaborative combat capabilities of fire brigades and related personnel.

[0003] Currently, some fire simulation training technologies use fixed smoke generators instead of open flames to simulate fire environments, making the simulation training safer. However, the timing, concentration, and range of smoke release in most systems are preset, making it difficult to adjust and dynamically respond in real time based on the effectiveness of the "firefighting operation" during training. For example, it is impossible to intuitively simulate the reduction of smoke after the fire is effectively suppressed, or the loss of control of the fire due to ineffective firefighting. The feedback on the training effect is not intuitive, and it is difficult to simulate whether the final firefighting operation was successful. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a grassland fire simulation training system, aiming to solve the problems mentioned in the background technology.

[0005] To achieve the above-mentioned technical objectives, the specific technical solution of the present invention is as follows: The present invention proposes a grassland fire simulation training system, including a central control module, a data collection module, a data feedback module, a smoke generation module, and a smoke exhaust unit. The smoke exhaust unit includes multiple smoke exhaust devices of different sizes and shapes, as well as a first smoke generation device and a second smoke generation device. The first smoke generation device is located at the center of the smoke exhaust device, and a first smoke pipe is connected between the first smoke generation device and the smoke exhaust device. A second smoke pipe is connected between adjacent smoke exhaust devices, and the second smoke generation device is connected to the second smoke pipe. The smoke exhaust device includes multiple arc-shaped smoke exhaust pipes and a four-way valve connected to the smoke exhaust pipes. A smoke exhaust assembly is connected to the smoke exhaust pipes. The smoke exhaust assembly includes an inner pipe and an outer pipe located inside and outside the smoke exhaust pipes. The surface of the outer pipe is provided with several smoke exhaust holes, and multiple smoke inlet pipes are connected to the inner pipe.

[0006] Preferably, the exhaust pipe is provided with an airbag chamber, and an airbag is provided inside the airbag chamber. The exhaust pipe is in contact with the surface of the airbag. When the airbag is saturated, it can drive the exhaust pipe to bend into a U-shaped structure. An exhaust valve is connected to the airbag.

[0007] Preferably, an elastic component is installed on the smoke inlet pipe. The elastic component includes a pair of rotating plates that are hinged to each other. Each rotating plate is rotatably connected to a retaining ring that is connected to the smoke inlet pipe. A torsion spring is installed on the rotating shaft of the rotating plate to apply elastic forces in opposite directions to the two rotating plates.

[0008] Preferably, one end of the exhaust pipe is provided with a slot, and a connecting pipe is fixedly connected between the outer pipe and the inner pipe, and the connecting pipe is connected to the slot; a smoke sensor is installed on the outer pipe.

[0009] Preferably, a water storage tank is installed on the surface of the outer pipe, and the smoke exhaust hole is located inside the water storage tank.

[0010] Preferably, the first smoke generating device includes a housing, a smoke generator installed inside the housing, and an air supply mechanism installed at the bottom of the housing, and the surface of the housing is provided with a smoke outlet that is connected to the first smoke pipe.

[0011] Preferably, a control component is installed inside the housing to regulate the opening degree of the smoke outlet. The control component includes a fixed base, a rotating base rotatably connected to the fixed base, and a valve plate fixedly connected to the rotating base. The valve plate is in contact with the inner wall of the housing, and the surface of the valve plate is provided with a valve hole corresponding to the smoke outlet. The inner diameter of the valve hole gradually increases from one end to the other end.

[0012] Preferably, a rotating shaft is rotatably connected below the fixed base, and a blade is fixedly connected to the lower end of the rotating shaft. The rotating shaft drives the rotating base to rotate through a transmission mechanism.

[0013] Preferably, the transmission mechanism includes an incomplete central gear, a gear ring, and planetary gears. The incomplete central gear is fixedly mounted on a rotating shaft, the gear ring is fixedly connected to a rotating seat, the planetary gears are mounted on a planet carrier, and the planet carrier is fixedly connected to a fixed seat.

[0014] Preferably, the control component further includes a drive gear meshing with the gear ring, a rotating rod fixedly connected to the drive gear, and a clearance hole on the rotating seat that cooperates with the rotating rod.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. The airbag, smoke inlet pipe, and elastic component in the smoke exhaust assembly of this invention constitute an intelligent feedback unit. When the simulated fire point is not effectively extinguished, the airbag deflates, causing the smoke inlet pipe to form an L-shape, and smoke continues to be discharged, visually indicating that the fire is not under control. When the fire is extinguished in time and there is sufficient water, the water will be stored in the U-shaped smoke inlet pipe to form a liquid seal, physically blocking the smoke discharge, clearly and objectively simulating that the open flame has been extinguished; thus effectively simulating whether the firefighting operation was successful.

[0017] 2. The control component of this invention, through a rotating shaft, blades, and a transmission mechanism, enables the system to convert natural wind or airflow generated during simulated firefighting into control signals. When the wind force changes, the blades drive the rotating shaft to rotate, which in turn adjusts the valve plate angle through the gear mechanism to control the opening size of the smoke outlet, automatically simulating the phenomenon of fire spreading and improving the system's simulation realism for complex environmental conditions.

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Example: This example discloses a grassland fire simulation training system, such as... Figures 1-10As shown, the system includes a central control module, a data collection module, a data feedback module, a smoke generation module, and a smoke emission unit. The data collection module collects grassland fire data, the data feedback module feeds the monitored fire data back to the central control module, and the central control module controls the start and stop of the smoke generation module and the smoke emission unit. In this embodiment, the smoke emission unit includes multiple smoke emission devices 100 of different sizes and shapes, a first smoke generation device 200, and a second smoke generation device 300. The smoke emission devices 100 are ring-shaped with inner and outer rings. Smoke gradually diffuses from the inner ring smoke emission device 100 to the outer ring smoke emission device 100, simulating the spread of a grassland fire. The first smoke generation device 200 is located at the center of the innermost smoke emission device 100. The first smoke generation device 200 and the smoke emission device 300... A first smoke pipe 400 is connected between the devices 100. A first smoke generating device 200 is used to supply smoke to the innermost smoke outlet device 100. A second smoke pipe 500 is connected between adjacent smoke outlet devices 100. A second smoke generating device 300 is connected to the second smoke pipe 500 and is used to supply smoke to the outer smoke outlet devices 100. The first smoke generating device 200 and the second smoke generating device 300 have the same structure. The smoke outlet device 100 includes a plurality of arc-shaped exhaust pipes 110 and a four-way valve 130 connected to the exhaust pipes 110. The first smoke pipe 400 and the second smoke pipe 500 are both connected to the four-way valve 130. An exhaust assembly 120 is connected to the exhaust pipe 110. After the smoke enters the exhaust pipe 110, it is discharged through the exhaust assembly 120.

[0031] like Figures 4-6As shown, the smoke exhaust assembly 120 includes an inner pipe 122 and an outer pipe 121 respectively disposed inside and outside the smoke exhaust pipe 110. The outer pipe 121 has several smoke exhaust holes 124 on its surface, through which smoke is discharged to the external environment. Multiple smoke inlet pipes 127 are connected to the inner pipe 122, through which smoke from the smoke exhaust pipe 110 enters the inner pipe 122 and then the outer pipe 121. An airbag chamber 112 is provided inside the smoke exhaust pipe 110, and an airbag 113 is located inside the airbag chamber 112. The smoke inlet pipe 127 contacts the surface of the airbag 113. When the airbag 113 is saturated, it compresses the smoke inlet pipe 127, causing it to bend into a U-shaped structure. An air outlet valve 114 is connected to the airbag 113. During firefighting training, the air in the airbag 113 is slowly released through the air outlet valve 114. During the venting process, the smoke inlet pipe 127 changes from a U-shape to an L-shape. Before the smoke inlet pipe 127 changes to an L-shape, if the fire is extinguished in time and the water volume is large enough, the water will enter the outer pipe 121 and inner pipe 122 through the smoke exhaust hole 124, and finally enter and fill the U-shaped smoke inlet pipe 127, sealing the smoke inlet pipe 127. If the smoke exhaust assembly 120 cannot exhaust the smoke, it means that the firefighting operation is successful. If the water volume is insufficient to fill the smoke inlet pipe 127 before it completely changes to an L-shape, it cannot seal the smoke inlet pipe 127. When the smoke inlet pipe 127 completely changes to an L-shape, it cannot be sealed, and the smoke exhaust assembly 120 continues to exhaust the smoke, which means that the fire is out of control and the firefighting operation has failed. This provides a direct feedback on the result of the firefighting operation.

[0032] The smoke exhaust pipe 110 has a slot 111 at one end, and a connecting pipe 123 is fixedly connected between the outer pipe 121 and the inner pipe 122. The connecting pipe 123 engages with the slot 111, allowing the smoke exhaust assembly 120 to be detached from the smoke exhaust pipe 110. Furthermore, in this embodiment, a smoke sensor 126 is installed on the outer pipe 121. The smoke sensor 126 is used to monitor the smoke concentration inside the outer pipe 121, reflecting the size of the fire. When the smoke sensor 126 detects smoke, it sends a signal to the central control module, which then controls the second smoke generator 300 to start. During the firefighting process, when water enters the smoke inlet pipe 127 and forms a physical seal, the smoke sensor 126 detects a significant reduction in the smoke concentration inside the outer pipe 121, indicating that the firefighting operation is successful. The smoke sensor 126 sends the data to the central control module, which then controls the exhaust valve 114 to close, the airbag 113 to stop deflating, and the smoke inlet pipe 127 to remain in a U-shape.

[0033] like Figure 7As shown, an elastic component 128 is installed on the smoke inlet pipe 127. The elastic component 128 includes a pair of rotating plates 1281 that are hinged to each other. Each rotating plate 1281 is rotatably connected to a retaining ring 1283 that is connected to the smoke inlet pipe 127. A torsion spring 1282 is installed on the rotating shaft of the rotating plate 1281 to apply elastic forces in opposite directions to the two rotating plates 1281. During the deflation of the airbag 113, the elastic component 128 drives the smoke inlet pipe 127 to change from a U-shaped state to an L-shaped state.

[0034] Preferably, a water storage tank 125 is installed on the surface of the outer pipe 121, and the smoke exhaust hole 124 is located inside the water storage tank 125, so that more water can enter the outer pipe 121 through the water storage tank 125.

[0035] like Figures 8-10 As shown, the first smoke generating device 200 includes a housing 210, a smoke generator 220 installed inside the housing 210, and an air supply mechanism 240 installed at the bottom of the housing 210. The bottom of the housing 210 is provided with support legs. The air supply mechanism 240 uses a fan to transport smoke to the smoke outlet device 100. The surface of the housing 210 is provided with a smoke outlet hole 250 that mates with the first smoke pipe 400. A control component 230 is installed inside the housing 210 to adjust the opening degree of the smoke outlet hole 250, thereby controlling the smoke delivery speed and simulating the phenomenon of fire spread. The control component 230 includes a fixed base 231 fixedly connected to the housing 210, a rotating base 232 rotatably connected to the surface of the fixed base 231, and a component fixedly connected to the rotating base 232. The valve plate 233 has a pair of valves that fit against the inner wall of the housing 210. The surface of the valve plate 233 has valve holes 234 corresponding to the smoke outlet 250. The inner diameter of the valve holes 234 gradually increases from one end to the other. A rotating shaft 235 is rotatably connected below the fixed base 231. A blade 236 is fixedly connected to the lower end of the rotating shaft 235. The rotating shaft 235 drives the rotating base 232 to rotate through the transmission mechanism. When the air supply mechanism 240 is started, it drives the blade 236 and the rotating shaft 235 to rotate slowly. When the rotating shaft 235 rotates, it drives the rotating base 232 to rotate through the transmission mechanism. The rotating base 232 drives the valve plate 233 to move, thereby continuously increasing the opening degree of the smoke outlet 250 and continuously increasing the smoke delivery speed, simulating the phenomenon that the fire is getting bigger and bigger.

[0036] Preferably, the transmission mechanism includes an incomplete central gear 239, a gear ring 237, and a planetary gear 238. The incomplete central gear 239 is fixedly mounted on the rotating shaft 235, the gear ring 237 is fixedly connected to the rotating seat 232, and the planetary gear 238 is mounted on the planet carrier, which is fixedly connected to the fixed seat 231. When the rotating shaft 235 rotates, it drives the incomplete central gear 239 to rotate. When the incomplete central gear 239 rotates, it drives the gear ring 237 to rotate intermittently through the planetary gear 238, which in turn drives the valve plate 233 to move intermittently, thereby continuously opening the smoke outlet 250.

[0037] Preferably, the control component 230 further includes a drive gear 2310 meshing with the gear ring 237. A rotating rod 2311 is fixedly connected to the drive gear 2310. The rotating rod 2311 is rotatably connected to the housing 210. The upper end of the rotating rod 2311 extends to the outside of the housing 210, and a handle is provided at the upper end of the rotating rod 2311. The rotating seat 232 is provided with a clearance hole 2312 that cooperates with the rotating rod 2311. The gear ring 237 and the valve plate 233 can be reset by manually rotating the drive gear 2310.

[0038] Working principle: After the smoke extraction unit is assembled, the system starts up. The central control module controls the first smoke generator 200 to generate smoke simulating a fire. The first smoke generator 200 is located at the center of the innermost annular smoke extraction device 100, and the smoke it generates is transported to the innermost smoke extraction device 100 through the first smoke pipe 400. Starting from the center (fire source center), when the smoke sensor 126 in the inner circle detects smoke, it sends the data to the central control module. The central control module then controls the second smoke generator 300 to operate, providing smoke to the outermost smoke extraction device 100. The smoke is supplied and diffuses outwards in concentric circles, simulating the spread of fire; it visually simulates the spread of a grassland fire from its ignition point. At the start of the firefighting training, the airbag 113 inside the smoke exhaust assembly 120 is saturated with air, which compresses the smoke inlet pipe 127 in contact with it, bending it into a U-shape. At this time, the exhaust valve 114 automatically opens, and the airbag 113 begins to slowly deflate, simulating the countdown mechanism of the "golden time" for firefighting. Before the airbag 113 is completely deflated, the smoke inlet pipe 127 has a chance to be water-sealed; after deflation, the smoke inlet pipe 127 becomes L-shaped. Unable to be sealed again; trainees use water guns and other tools to spray water to extinguish the simulated fire (smoke exhaust device 100); if the fire is extinguished in time and the water volume is sufficient, the water flows through the smoke exhaust hole 124 into the outer pipe 121 and the inner pipe 122, eventually filling the still U-shaped smoke inlet pipe 127. The water forms an effective physical seal at the bottom of the U-shaped bend, blocking the smoke exhaust channel; at this time, the smoke sensor 126 detects a sudden drop in the smoke concentration in the outer pipe 121 and sends this signal to the central control module. The central control module immediately closes the exhaust valve 114 and stops the airbag 113 from deflating, so that... The smoke inlet pipe 127 is maintained in a sealable U-shape and can indicate "firefighting successful" through sound and light. If the fire is not extinguished in time, the airbag 113 continues to depress before an effective water seal is formed. With the assistance of the elastic component 128, the smoke inlet pipe 127 gradually straightens from a U-shape to an L-shape. Once the smoke inlet pipe 127 becomes an L-shape, water can no longer remain in it to form a seal, and the smoke exhaust component 120 continuously exhausts smoke, simulating "fire out of control". The system can then determine "firefighting operation failed", thus achieving a high degree of simulation of the training process and real-time, objective feedback of the results.
