Description

Technical Field

[0001] This invention relates to the field of fire training technology, and more specifically to an underground fire simulation training system. Background Technology

[0002] To raise fire prevention and safety awareness, participation in fire drills is generally encouraged. Through hands-on experience with different scenarios, firefighters gain a deeper understanding of fire risks and increase their vigilance. Fire is a dangerous and urgent disaster; therefore, appropriate fire drills can improve firefighters' ability to react quickly and calmly in real fire situations. Simulated fire scenarios also enhance firefighters' ability to avoid blind escapes in actual fire accidents. Therefore, fire drills are an important part of firefighters' routine training. Current fire drills include various scenario types, with underground training being a common component. Due to the unique and complex nature of underground training scenarios, various simulations are required.

[0003] For example, Chinese patent with authorization announcement number "CN104850052 B" and title "Fire Emergency Drill Simulation System and Simulation Method" provides a fire emergency drill simulation system and method. This system includes a real fire system capable of realistically simulating a fire scene, enhancing trainees' crisis awareness. The simulated well site equipment provides trainees with devices for handling fire situations, and the UWB positioning system can locate the trainees' escape position when the emergency is under control or out of control.

[0004] The shortcomings of the existing technology are that, in general, most of the training in the existing technology is conducted through a real fire system, such as the one mentioned in the patent above. This real fire system usually sprays onto the ground and cannot comprehensively train the trainees, thus having certain simulation limitations. Summary of the Invention

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0046] Please refer to 1-20, an underground fire simulation training system, including a central control module and a safety protection module, and also a roof-mounted pyrotechnic module. The roof-mounted pyrotechnic module is installed on the top beam 55. The roof-mounted pyrotechnic module includes a roof-mounted fire-spraying unit and a roof-mounted water-jetting unit. The roof-mounted fire-spraying unit sprays pyrotechnic flames instantaneously in the direction of the inclined box roof. The roof-mounted water-jetting unit is installed above the roof-mounted fire-spraying unit to extinguish and cool the pyrotechnic flames.

[0047] This invention, through the installation of a roof-mounted burst fire module in the roof frame 51, and the coordination of a roof-mounted fire-spraying unit and a roof-mounted water-jetting unit, enables the instantaneous burst fire to be sprayed onto the underground roof during actual training. This allows for training of trainees in handling burst fire from above, further enhancing their ability to cope with sudden bursts of fire, and thus comprehensively improving the training effect.

[0048] In a further embodiment of the present invention, an oil drum fire training module and a flowing fire training module are also included, wherein the oil drum fire training module is ignited by electronic ignition.

[0049] In a further embodiment of the present invention, a high-temperature training module for the door panel is also included. The high-temperature training module for the door panel is heated internally by a heating device. The explosion simulation fire training module is set on the side wall of the tunnel wall 1 and is activated by an electronic sensor.

[0050] In a further embodiment of the present invention, a ceiling mechanism is also included. The ceiling flame-spraying unit is disposed on the ceiling mechanism, and the ceiling mechanism includes a rotating telescopic rod 5 rotatably disposed on a top beam 55. A rectangular frame is movably disposed at the lower end of the rotating telescopic rod 5. A plurality of first nozzles 531 are disposed on one side of the rectangular frame, and the first nozzles 531 are used to spray out burst flames. The present invention uses the first nozzles 531 and corresponding structures in conjunction with each other, disposed on the rotating telescopic rod. That is, the first nozzles 531 are disposed on the telescopic rod to spray flames towards the ceiling. Moreover, the rotating telescopic rod 5 can be adjusted as needed, so that the top of the rotating telescopic rod 5 can rotate along the axis with the top beam 55. During rotation, the water head and the first nozzles 531 can gradually move obliquely closer to the top of the top beam 55, so that the burst flames can move more along the top of the top beam 55, thereby improving the burst effect at the top.

[0051] Furthermore, two connecting rods 52 are movably arranged on the rotating telescopic rod 5, and multiple sets of water spraying mechanisms 521 are movably arranged on the connecting rods 52. The water spraying mechanism 521 includes multiple water spray heads, and a connecting shaft 522 is fixedly connected between each water spray head. The connecting shaft 522 is rotatably arranged on the connecting rod 52.

[0052] The water spray head is tilted toward the first nozzle 531.

[0053] Furthermore, multiple flow pipes 5211 are provided between the two connecting rods 52, and each flow pipe 5211 corresponds to one of the water spraying mechanisms 521. One end of the water spray head is connected to a connecting hose 5212, which passes through the flow pipes 5211.

[0054] Furthermore, a pressure rod 54 is fixedly installed on the side wall of the rotating telescopic rod 5, and a fixed baffle 5311 is fixedly installed on one of the spray nozzles. During the rotation of the rotating telescopic rod 5, the pressure rod 54 can abut against the fixed baffle 5311, thereby driving the spray nozzle to rotate along the connecting shaft 522 towards the top beam 55. By using the pressure rod 54 and the fixed baffle 5311 in cooperation, this invention can achieve the following: after the rotating telescopic rod 5 rotates, the pressure rod 54 can press against the fixed baffle 5311. That is, when the first nozzle 531 is close to the top beam 55, the water spray can passively rotate towards the position of the top beam 55, that is, it can spray the position of the top beam 55, which can not only extinguish the fire, but also reduce the excessive temperature of the top beam 55 caused by the sudden fire.

[0055] Furthermore, it also includes a tunnel rescue module and a tunnel rescue module collapse training unit. The collapse training unit is set inside the tunnel wall 1, and the collapse unit includes a bearing mechanism for bearing the collapsed material. The bearing component is set in the bottom channel of the tunnel wall 1. When the weighing component is subjected to gravity, the bearing mechanism is driven to open through the transmission mechanism so that the collapsed material falls. The bearing mechanism has a bearing position where it bears the collapsed material. It also includes a locking mechanism for locking the bearing mechanism in the bearing position.

[0056] It also includes a load-bearing component, which is located at the bottom of the tunnel. When the load-bearing component is under pressure, it drives the transmission mechanism to unlock the locking mechanism, so that the load-bearing mechanism opens and the collapsed material falls.

[0057] Specifically, the present invention, through the coordinated use of the load-bearing components and the transmission mechanism, and then through the coordinated use of the locking mechanism and the bearing mechanism, enables the first bearing plate 21 and the second bearing plate 22 to press downward when the trainee is under pressure, that is, to drive the fixed block 411 to move downward, that is, to enable the locking mechanism to be passively unlocked through the coordinated use of the transmission mechanism, that is, to allow the collapsed object on the bearing mechanism to fall, that is, to enable collapse training.

[0058] In a further embodiment of the present invention, there are two bearing mechanisms. The bearing mechanism includes a holding frame 12 disposed on the tunnel wall 1 and a rotating plate 32 rotatably disposed below the holding frame 12. A sliding plate 31 is slidably disposed on the rotating plate 32, and a locking mechanism is disposed on the sliding plate 31.

[0059] In a further embodiment of the present invention, a side fixing plate 11 is provided above and below the holding frame 12, and the locking mechanism includes a guide shaft 33. A locking block 331 is slidably provided on the guide shaft 33 along the circumferential direction. The guide shaft 33 is inserted into a limiting slide groove 1101 opened on the side fixing plate 11. A second locking groove 1103 adapted to the locking block 331 is opened above the limiting slide groove 1101. When the locking block 331 is inserted into the second locking groove 1103, the bearing mechanism is locked.

[0060] In a further embodiment of the present invention, the limiting groove 1101 is opened from top to bottom towards the rotating plate 32. When the locking mechanism is unlocked, the rotating plate 32 and the sliding plate 31 move downward. During the downward movement, the sliding plate 31 can gradually retract into the rotating plate 32 under the limiting guidance of the limiting groove 1101.

[0061] In a further embodiment of the present invention, the load-bearing component includes a second bearing plate 22 and a first bearing plate 21 rotatably mounted on the second bearing plate 22. The transmission mechanism includes a drive rod 41 vertically slidably mounted within the tunnel wall 1 and a fixing block 411 fixedly mounted below the drive rod 41. The fixing block 411 is located below the first bearing plate 21. A fourth elastic element 412 is sleeved on the outside of the drive rod 41. One end of the fourth elastic element 412 is fixedly connected to the bottom of the drive block, and the other end abuts against the tunnel wall 1. Under its elastic force, it can... This allows the drive block 43 to have an upward tendency, that is, it allows the fixed block to abut against the pivot position of the first support plate 21 and the second support plate 22, so that the abutment block 421 does not insert into the second locking groove 1103. A support base plate 212 is provided below the first support plate 21 and the second support plate 22, and one end of the second support plate 22 is slidably mounted on the support base plate 212. When the trainee steps on the second support plate or the first support plate, the second support plate 22 is triggered to slide along the support base plate 212, and then the fixed block 411 moves downward.

[0062] In a further embodiment of the present invention, a driving block 43 is fixedly disposed above the fixed block 411, and a hinged movable rod 44 is rotatably disposed at one end of the driving block 43, and a transmission rod 441 is rotatably disposed at one end of the hinged movable rod 44, and a hinged rod 42 is rotatably disposed at one end of the transmission rod 441. The hinged rod 42 is rotatably disposed in the side fixed plate 11, and an abutment block 421 is rotatably disposed at the other end of the transmission rod 441. One end of the abutment block 421 is inserted into the second locking groove 1103. When the load-bearing component is compressed, the abutment block 421 is driven to move into the second locking groove 1103 through the transmission mechanism, so that the locking block 331 disengages from the second locking groove 1103.

[0063] Specifically, the first bearing plate 21 and the second bearing plate 22 are equipped with lifting devices, which can drive the first bearing plate 21 and the second bearing plate 22 to rise. After the collapse training is completed, the trainee passes through the second bearing plate 22, and then the lifting device drives the load-bearing component to move upward. At this time, the collapsed object is on the load-bearing component. Then, as the load-bearing component moves upward, it gradually squeezes the rolling shaft 311. Then, the rolling shaft 311 abuts in the groove on the first bearing plate 21 and the second bearing plate 22. Then, as the load-bearing component moves upward, it gradually squeezes the rolling shaft 311, which then gradually drives the locking and guide shaft 33 to move. Then, the guide shaft 33 gradually slides along the limiting groove 1101. Then, when sliding, due to the limitation of the limiting groove 1101, the guide shaft 33 gradually moves away from the rotating plate 32. Then, when moving away, it gradually drives the sliding plate 31 to move outward, so that the sliding plate 31 gradually extends and retracts outward. Furthermore, it can lift up the collapsed material on the load-bearing component. After the sliding plate 31 and the rotating plate 32 move to a certain position, the locking block 331 moves to the direction of the second locking groove 1103. Then, under the elastic force of the second elastic member 3322, the locking block 331 is inserted into the second locking groove 1103. That is, the sliding plate 31 and the rotating plate 32 can be locked at that position. In other words, the collapsed material can be placed on the rotating plate 32 and the sliding plate 31 and restricted by the holding frame 12. Then the load-bearing component is lowered to the lowest position by the lifting device.

[0064] Specifically, it also includes a buffer locking assembly, which includes a third elastic element 1112 disposed within the limiting slide groove 1101. One end of the third elastic element 1112 is provided with a buffer block 111, and the other end is fixedly disposed within the limiting slide groove 1101. A first locking groove 1102 is also provided within the limiting slide groove 1101, and the first locking groove 1102 is adapted to the locking block 331. One end of the rolling shaft 311 is slidably disposed on the sliding plate 31, and a sliding rod 332 is slidably disposed within the rolling shaft 311 along the axial direction. A guide post 3321 is slidably disposed on the sliding rod 332, and the guide post 3321 is inserted into the sliding plate 31. Within the extrusion groove 3111 on the plate 31, when the sliding plate 31 moves toward the rotating plate 32, the guide post 3321 moves along the direction of the extrusion groove 3111, which in turn drives the sliding rod 332 to move toward the sliding plate 31, thereby causing the locking block 331 to disengage from the first locking groove 1102. The sliding rod 332 is slidably sleeved with a sliding block 34, and the sliding block 34 is slidably connected to the sliding plate 31. The sliding rod 332 is sleeved with a first elastic element 3311, one end of which abuts against the side wall of the locking block 331, and the other end abuts against the side wall of the guide shaft 33.

[0065] That is, the present invention, through the buffer locking component, enables the sliding plate 31 and the rotating plate 32 to rotate when the bearing mechanism is locked, and then the rolling shaft 311 abuts against the buffer block 111, thereby buffering the falling sliding plate 31. During the buffering process, the locking block 331 is inserted into the first locking groove 1102, that is, the sliding plate 31 can be locked in that position. Thus, it can not only buffer the downward movement of the sliding plate 31 and the rotating plate 32, but also lock the buffered sliding plate 31, that is, it can greatly improve the stability of the device.

[0066] In practical use, the trainee first moves to the lane position, then moves onto the load-bearing component. The load-bearing component is then pressed and moves downward, causing the fixed block 411 to move downward, which in turn causes the drive rod 41 to move downward. Through the coordinated use of the hinged movable rod 44 and the transmission rod 441, the abutment block 421 at one end of the hinged rod 42 can be inserted into the second locking groove 1103, that is, the locking block 331 in the second locking groove 1103 can be squeezed out. When the locking block 331 is completely disengaged from the second locking groove 1103, the sliding plate 31 unlocks and rotates. During the rotation, the rolling shaft 311 slides downward along the limiting groove 1101, that is, the collapsed property on the sliding plate 31 and the rotating plate 32 falls down. As it moves downward along the limiting groove 1101, the limiting groove 1101 gradually opens towards the rotating plate 32 from top to bottom. This allows the sliding plate 31 to gradually retract into the rotating plate 32 during the downward movement. This not only reduces the obstruction to the falling of the collapsed material, but also greatly reduces the space occupied by the sliding along the holding frame 12 after rotation. Then, the collapsed material falls, realizing the training of the trainee.During the downward movement, the rolling shaft 311 eventually abuts against the buffer block 111, thus cushioning the falling sliding plate 31. During this cushioning process, the locking block 331 inserts into the first locking groove 1102, locking the sliding plate 31 in that position. This not only cushions the downward movement of the sliding plate 31 and rotating plate 32 but also locks the cushioned sliding plate 31, ensuring its stability. After the trainee passes the second support plate 22, the lifting device drives the load-bearing component upward. The collapsed material is now on the load-bearing component. As the load-bearing component moves upward, it gradually compresses the rolling shaft 311, causing it to abut against the grooves on the first support plate 21 and the second support plate 22. The upward movement of the load-bearing component further compresses the rolling shaft 311, causing it to gradually drive the locking block 331 and the guide shaft 33 to move. Shaft 33 gradually slides along the limiting groove 1101. During this sliding, due to the limiting of the limiting groove 1101, the guide shaft 33 gradually moves away from the rotating plate 32. That is, the sliding plate 31 gradually moves towards the center of the load-bearing component, gradually driving the sliding plate 31 to move outward. This causes the sliding plate 31 to gradually extend and retract outward. During this process, the sliding plate 31 can lift the collapsed material on the load-bearing component, allowing the collapsed material to gradually fall between the sliding plate 31 and the rotating plate 32. Above 2, after the sliding plate 31 and rotating plate 32 have moved to a certain position, the locking block 331 moves to the direction of the second locking groove 1103. Then, under the elastic force of the second elastic member 3322, the locking block 331 inserts into the second locking groove 1103, that is, the sliding plate 31 and rotating plate 32 can be locked in this position. In other words, the collapsed material can be placed on the rotating plate 32 and sliding plate 31 and restricted by the holding frame 12. Then the load-bearing component is lowered to the lowest position by the lifting device.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
