Description

Technical Field

[0001] This invention belongs to the technical field of fire simulation devices, specifically relating to a forest surface fire rescue simulation device. Background Technology

[0002] With global warming, forest fires are becoming increasingly frequent, posing a significant threat to natural ecosystems and human society. Forest surface fires, as one of the main types of forest fires, present higher demands on fire and rescue operations due to their rapid spread and unpredictability. Traditional fire and rescue training methods are often limited by the uncontrollable and dangerous nature of actual fire scenes, making it difficult to comprehensively and effectively improve firefighters' practical skills. Existing simulation devices involve laying gas pipelines at the training ground and installing flame-emitting devices on these pipelines to simulate flames. However, these existing simulation devices have certain drawbacks: they can only be customized according to the training site, meaning that once put into use, they do not require adjustments for different usage scenarios, resulting in significant limitations in their application. Summary of the Invention

[0003] The purpose of this invention is to provide a forest surface fire rescue simulation device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a forest surface fire rescue simulation device, comprising a movable base parallel to a horizontal plane and a guide member arranged perpendicular to the horizontal plane, the guide member being above the movable base and having multiple toothed grooves along its own length direction, a movable frame arranged on the guide member along its own length direction, a support plate fixedly connected to the side of the movable frame facing the movable base, a gear matching the toothed grooves being rotatably connected inside the movable frame, a flexible air guide tube fixedly connected between the support plate and the movable base, and a flame-spraying component for ejecting flames being provided at the top of the air guide tube and the top of the movable base.

[0005] Preferably, a base is provided below the movable seat, and two mounting brackets are symmetrically fixedly connected to the top of the base. A first lead screw is rotatably connected inside each of the two mounting brackets, and a first motor is fixedly connected to one side of each of the two mounting brackets. The output end of the first motor is connected to one of the first lead screws. A movable moving plate is sleeved on each of the two first lead screws. The movable seat is fixedly connected between the two moving plates. A first side plate is fixedly connected to both sides of the base, and a first screw is installed on the first side plate.

[0006] Preferably, an air intake pipe and two gas intake pipes are fixedly connected to the side of the movable seat away from the air duct, and a mixing chamber is formed inside the movable seat. The air intake pipe is located between the two gas intake pipes, and both the air intake pipe and the two gas intake pipes are connected to the mixing chamber.

[0007] Preferably, a second motor is fixedly connected to the movable frame, and the output end of the second motor is connected to a gear.

[0008] Preferably, the guide member includes a base plate, both sides of the base plate are recessed to form guide grooves, the toothed groove is located between the two guide grooves, and two limiting protrusions are symmetrically fixedly connected to the inner wall of the movable frame, the limiting protrusions matching the guide grooves;

[0009] The top and bottom of the substrate are both fixedly connected to a second side plate, and a second screw is installed on the second side plate.

[0010] Preferably, the flame-emitting component includes a flame-emitting head, the inside of which is formed, from bottom to top, a communicating inner cavity and a combustion chamber, and an igniter is fixedly connected inside the combustion chamber.

[0011] Preferably, a vent plate is fixedly connected inside the inner cavity, and a movable connecting rod is provided between the combustion chamber and the inner cavity. The bottom of the connecting rod moves through the vent plate, and the top of the connecting rod is inside the combustion chamber. A sealing head for blocking the vent plate is sleeved on the connecting rod, and a spring is fixedly connected between the bottom of the sealing head and the top of the vent plate.

[0012] Preferably, the connecting rod has an outwardly convex annular protrusion on its circumference, and the annular protrusion is located between the combustion chamber and the inner cavity.

[0013] Preferably, a draining groove is formed inside the flame head, the inlet end of the draining groove is connected to the combustion chamber, and the outlet end of the draining groove is connected to the outside. The horizontal height of the inlet end of the draining groove is higher than the horizontal height of the outlet end of the draining groove.

[0014] Preferably, a conical head is fixedly connected to the top of the connecting rod, and the diameter of the conical head gradually decreases from the top to the bottom.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) The present invention uses gears to rotate inside the mobile frame, and through the tooth grooves on the guide, the mobile frame and support plate move along the length of the guide. The guide drives the air pipe to move, thereby adjusting the inclination of the air pipe. This allows the device to be adjusted according to different usage scenarios, making it easier to adjust according to the slope of the mountain forest, and better suited to the rescue scenario of forest surface fire, thus increasing the scope of use of the device.

[0017] (2) After the slope of the air duct is adjusted by the support plate, the present invention drives the lead screw to rotate by the first motor, thereby allowing the moving plate to move along the lead screw, which in turn drives the moving seat to move, and the moving seat drives the air duct to move, so that the air duct is re-tensioned, making the air duct more stable when in use and making it easier for trainees to train.

[0018] (3) When the mixed gas is delivered into the inner cavity, the sealing head is pushed by the mixed gas, so that the sealing head pulls the spring synchronously when it moves until the inner cavity and the combustion chamber are connected. After the mixed gas stops being discharged, the connecting rod and the annular protrusion move back to their original positions under the action of the spring to separate the inner cavity and the combustion chamber, so as to prevent the water inside the combustion chamber from being discharged through the drain tank, so that the water inside the combustion chamber will not accumulate, and the device can be used normally outdoors.

[0019] (4) When the connecting rod moves back to its original position under the action of the spring, the present invention drives the conical head to move synchronously through the connecting rod, thereby blocking the combustion chamber with the conical head, so that the water is quickly discharged from both sides of the conical head, further reducing the probability of water accumulating inside the combustion chamber.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-7 As shown, the present invention provides the following technical solution: a forest surface fire rescue simulation device, including a movable seat 8 parallel to the horizontal plane and a guide member arranged perpendicular to the horizontal plane. The guide member is located above the movable seat 8, and the guide member forms multiple toothed grooves 16 along its own length direction. A movable frame 19 is arranged on the guide member along its own length direction. A support plate 21 is fixedly connected to the side of the movable frame 19 facing the movable seat 8. A gear 20 matching the toothed grooves 16 is rotatably connected inside the movable frame 19. A flexible air guide tube 12 is fixedly connected between the support plate 21 and the movable seat 8. A flame-spraying component 11 for spraying flames is provided at the top of the air guide tube 12 and the top of the movable seat 8.

[0030] Using the above technical solution, when personnel are conducting forest fire rescue operations, since most forests are located in sloping mountainous areas, before the device is put into use, the mobile base 8 is laid out at the training location, placed horizontally, and then the guide is pulled to move it along the slope, fixing it to the hillside. The guide's horizontal height is higher than that of the mobile base 8, thus tilting the air pipe 12. Once the guide is fixed, if personnel need to adjust the tilt of the air pipe 12 according to the hillside, the gear 20 rotates inside the mobile frame 19, and the gear groove 16 engages to move the air pipe 12. The frame 19 moves along the length of the guide member. When the frame 19 moves, it will drive the support plate 21 to move together. The support plate 21 drives the gas pipe 12 to move, thereby adjusting the height of one end of the gas pipe 12 and thus adjusting the inclination of the gas pipe 12. This allows the device to be adjusted according to the slope of the hillside. After the device is adjusted, the gas pipeline is connected to the moving base 8. After the gas is delivered to the moving base 8 and the gas pipe 12, it is sprayed out for combustion through the cooperation of the flame-spraying component 11, thereby simulating a forest surface fire. Personnel can then conduct simulation training, making it convenient for use in different scenarios.

[0031] After the personnel adjust the position of the air tube 12, in order to tighten the air tube 12 and make it more stable, such as... Figures 1-3 As shown, a base 1 is provided below the movable seat 8, and two mounting brackets 4 are symmetrically fixedly connected to the top of the base 1. The interior of each mounting bracket 4 is rotatably connected to a first lead screw 5, and a first motor 7 is fixedly connected to one side of each mounting bracket 4. The output end of the first motor 7 is connected to one of the first lead screws 5. A movable moving plate 6 is sleeved on each of the two first lead screws 5. The movable seat 8 is fixedly connected between the two moving plates 6. A first side plate 2 is fixedly connected to both sides of the base 1, and a first screw 3 is installed on the first side plate 2.

[0032] With the above technical solution, when the support plate 21 moves downward under the action of the moving frame 19, the tension of the air guide tube 12 will decrease. In order to re-tension the air guide tube 12, before the device is put into use, the base 1 is fixed in the position of use, and the first screw 3 is rotated through the first side plate 2 to fix the first side plate 2 and the base 1. After the position of the moving frame 19 is adjusted, the first motor 7 works, which drives the first lead screw 5 to rotate inside the mounting frame 4, so that the moving plate 6 moves along the length direction of the first lead screw 5. The two moving plates 6 drive the moving seat 8 to move, and the moving seat 8 drives the air guide tube 12 to move, so that the air guide tube 12 is re-tensioned and the air guide tube 12 is more stable after adjustment.

[0033] Regarding how air and gas are delivered to the interior of the movable seat 8, such as Figures 1-3An air intake pipe 10 and two gas intake pipes 9 are fixedly connected to the side of the movable seat 8 away from the air duct 12. A mixing chamber 24 is formed inside the movable seat 8. The air intake pipe 10 is located between the two gas intake pipes 9, and both the air intake pipe 10 and the two gas intake pipes 9 are connected to the mixing chamber 24.

[0034] A second motor 18 is fixedly connected to the movable frame 19, and the output end of the second motor 18 is connected to the gear 20.

[0035] With the above technical solution, before the device is used, the pipeline for transporting gas is connected to the gas inlet pipe 9, and the pipeline for transporting air is connected to the air inlet pipe 10. Air is transported into the mixing chamber 24 inside the moving base 8 through the air inlet pipe 10, and gas is transported into the mixing chamber 24 inside the moving base 8 through the gas inlet pipe 9, so that the gas and air are mixed. Finally, the mixed gas is sprayed out by the flame ejector 11 for combustion, thereby simulating a forest surface fire. When the drive gear 20 needs to be rotated, the second motor 18 works, so that the second motor 18 drives the gear 20 to rotate inside the moving frame 19, thereby driving the moving frame 19 to move along the guide.

[0036] Furthermore, in this invention, to make the movement of the movable frame 19 more stable, such as... Figures 1-5 As shown, the guide includes a base plate 13, with guide grooves 17 formed by recesses on both sides of the base plate 13. A toothed groove 16 is located between the two guide grooves 17. Two limiting protrusions 22 are symmetrically fixedly connected to the inner wall of the movable frame 19, and the limiting protrusions 22 match the guide grooves 17.

[0037] The top and bottom of the substrate 13 are fixedly connected to the second side plate 14, and the second side plate 14 is equipped with the second screw 15.

[0038] With the above technical solution, before the moving frame 19 is moved, the substrate 13 is fixed at the usage position, and then the second screw 15 is rotated through the second side plate 14. The substrate 13 is fixed by the second screw 15 abutting against the second side plate 14. The second motor 18 works, thereby driving the gear 20 to rotate inside the moving frame 19. The gear 20 and the tooth groove 16 cooperate to make the moving frame 19 move along the guide. When the moving frame 19 moves, the limiting protrusion 22 cooperates with the guide groove 17 to make the moving frame 19 move more smoothly.

[0039] Specifically, in one implementation, such as Figures 1-4 As shown, the flame-throwing component 11 includes a flame-throwing head 34. The inside of the flame-throwing head 34 forms a communicating inner cavity 31 and a combustion chamber 28 from bottom to top. An igniter 29 is fixedly connected inside the combustion chamber 28.

[0040] In this embodiment, after the gas and air are mixed in the mixing chamber 24, the mixed gas is transported to the inner chamber 31 of the burner head 34 for further mixing. The further mixed gas is transported to the combustion chamber 28, and the mixed gas is ignited by the igniter 29 to simulate a forest surface fire.

[0041] To prevent rainwater from flowing back into the inner cavity 31, a vent plate 33 is fixedly connected inside the inner cavity 31. A movable connecting rod 26 is provided between the combustion chamber 28 and the inner cavity 31. The bottom of the connecting rod 26 moves through the vent plate 33, and the top of the connecting rod 26 is inside the combustion chamber 28. A sealing head 32 for blocking the vent plate 33 is sleeved on the connecting rod 26, and a spring 23 is fixedly connected between the bottom of the sealing head 32 and the top of the vent plate 33.

[0042] In this embodiment, after the mixed gas is delivered into the inner cavity 31, it pushes the sealing head 32, causing it to move upward. As the sealing head 32 moves, it stretches the spring 23 until the sealing head 32 separates from the vent plate 33. The mixed gas is then delivered to the combustion chamber 28 through the vent plate 33. After the gas in the mixing chamber 24 enters the combustion chamber 28, it is ignited by the igniter 29 to simulate a fire. When the device stops delivering the mixed gas, the spring 23 is under negative pressure, which pulls the sealing head 32 and the connecting rod 26 back to their original positions.

[0043] After the connecting rod 26 is reset, in order to prevent rainwater from flowing back into the inner cavity 31, such as Figure 7 As shown, the connecting rod 26 has an annular protrusion 27 protruding outward from its circumference, and the annular protrusion 27 is located between the combustion chamber 28 and the inner cavity 31.

[0044] In this embodiment, when the device stops working, the annular protrusion 27 is engaged to seal the inner cavity 31 and the combustion chamber 28.

[0045] In addition, in order to facilitate the discharge of water, a drain trough 30 is formed inside the flame head 34. The inlet end of the drain trough 30 is connected to the combustion chamber 28, and the outlet end of the drain trough 30 is connected to the outside. The horizontal height of the inlet end of the drain trough 30 is higher than the horizontal height of the outlet end of the drain trough 30. A one-way valve is installed inside the drain trough 30.

[0046] In this embodiment, when the device stops working, the water remaining in the combustion chamber 28 is discharged through the drain tank 30.

[0047] A conical head 25 is fixedly connected to the top of the connecting rod 26, and the diameter of the conical head 25 gradually decreases from the top to the bottom.

[0048] In this embodiment, after the connecting rod 26 is reset, the probability of water entering the combustion chamber 28 is reduced by the cooperation of the conical head 25.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
