Description

Technical Field

[0001] The present invention relates to the technical field of fire simulation training, and particularly relates to a training device for the afterburning of Class A substances (wood). Background Art

[0002] Class A substance fires refer to fires involving solid substances. Such fires usually involve solid substances such as hay, wood, cotton, wool, linen, and paper. When these substances burn, they produce glowing embers. The afterburning phenomenon refers to the explosive or rapid combustion of hot smoke caused by the introduction of oxygen when the indoor ventilation is poor and the combustion is in an oxygen-deficient state;

[0003] After a fire occurs, different fire scenarios are likely to lead to different dangerous situations. Especially in the case of afterburning, because some firefighters have just joined the team or have not been able to intuitively feel the afterburning and other situations, it is easy to misjudge during disaster relief, resulting in injury to themselves. Therefore, training devices are usually needed to enable firefighters to more intuitively feel the fire scene. In existing afterburning training devices, when training, combustibles such as wood are usually burned inside to simulate the afterburning phenomenon for firefighters to train. After the training is over, combustion residue will remain in the training room. In order to facilitate the next training, firefighters usually need to enter to deal with the ashes and other residues. However, since the training room usually simulates the indoor situation, it is relatively enclosed as a whole. As a result, firefighters can only clean it bit by bit, resulting in a lot of time and effort spent on cleaning after the training is over. Summary of the Invention

[0004] The purpose of the present invention is to provide a training device for the afterburning of Class A substances (wood) to solve the above deficiencies in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solution: a backfire training device for class A substances (wood), including a training room and a door panel fixedly installed at its bottom end.

[0027] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] Please refer to Figures 1-8 , a re-ignition training device for Class A substances (wood), including a training room 1 and a door panel 3 fixedly installed at its bottom end. The door panel 3 is rotatably installed on the training room 1, and further includes:

[0029] A side baffle 41, which is vertically slidably installed on the side wall of the training room 1;

[0030] A connecting rod 42, which is fixedly installed above the side baffle 41, and the top end of the connecting rod 42 is fixedly installed with a top plate 43;

[0031] A rotating shaft 44, which is rotatably installed on the side wall of the training room 1. A rotating rod 45 is fixedly installed on the rotating shaft 44. Long plates 46 are provided at both ends of the rotating rod 45. One of the two long plates 46 is fixedly installed on the side baffle 41, and the other is slidably installed on the side wall of the training room 1;

[0032] A sealing plate 63, which is vertically slidably installed on the top plate 43, and a through hole 431 is provided on the top plate 43. The sealing plate 63 is used to close the through hole 431;

[0033] A bottom plate 51, a friction wheel 53 is fixedly installed on the side wall of the bottom plate 51. The friction wheel 53 is rotatably installed on the side wall of the training room 1, and a side rod 52 is fixedly installed on the side baffle 41;

[0034] When the rotating shaft 44 rotates, it will drive the side baffle 41 to rise. At the same time when the side baffle 41 rises, it will drive the bottom plate 51 to rotate upwards to pour out the combustibles in the training room 1. At the same time, when the rotating shaft 44 descends, it will drive the top plate 43 to squeeze air into the training room 1, so that the internal smoke and dust and combustibles are quickly squeezed out from the side wall;

[0035] Among them, a base 2 is fixedly installed at the bottom end of the training room 1, and the training room 1 can be conveniently placed through the base 2.

[0036] In another embodiment of the present invention: An electric push rod is fixedly installed on the inner wall of the side baffle 41, and the output end of the electric push rod is fixedly connected to the long board 46 slidably installed on the training room 1. Plug rods 47 are fixedly installed on the surfaces of the long boards 46, and rectangular slots are provided at both ends of the rotating rod 45;

[0037] Among them, when the training is over, there will be ashes of combustion residues in the training room 1. At this time, the electric push rod can be started. At this time, the electric push rod will drive the long board 46 thereon to move downward. As the upper long board 46 moves downward, it will move through the plug rod 47 on the surface in the slot of the rotating rod 45 to drive the rotating rod 45 to rotate by means of the rotating shaft 44. At this time, the lower end of the rotating rod 45 will move upward. When the lower end of the rotating rod 45 moves upward, it will drive the long board 46 on the side baffle 41 to move upward through the plug rod 47 at the lower end. At this time, the side baffle 41 will move upward to open the opening on the side wall of the training room 1. At the same time, as the side baffle 41 moves upward, it will drive the friction wheel 53 to rotate through the side rod 52. At this time, the friction wheel 53 will drive the bottom plate 51 to rotate upward, so that the bottom plate 51 tilts outward, so that the ashes on the bottom plate 51 are poured out through the side opening.

[0038] In another embodiment of the present invention: A connecting strip 62 is fixedly installed at the top end of the sealing plate 63. The top end of the connecting strip 62 is fixedly installed with an outer plate 61, and the size of the connecting strip 62 is smaller than the size of the through hole 431. A bottom rod 65 is fixedly installed at the bottom end of the sealing plate 63. A sliding frame 66 is horizontally slidably installed on the side wall of the training room 1, and chamfers are provided at both ends of the slider. A first spring 64 is fixedly installed between the outer plate 61 and the top plate 43;

[0039] Among them, referring to Figures 3-4 , when the side baffle 41 rises, it will drive the top plate 43 to rise through the connecting rod 42. When the top plate 43 rises, since the bottom rod 65 on the sealing plate 63 is located at the bottom end of the sliding frame 66, the sliding frame 66 will limit the rise of the sealing plate 63 at this time, and the through hole 431 will be opened. As the through hole 431 is opened, the flue gas can flow out from the through hole 431. At the same time, when the top plate 43 moves to close to the chamfer at the top end of the sliding frame 66, the top plate 43 will contact and squeeze the sliding frame 66 to make it move outward. At this time, the sliding frame 66 will move away on the surface of the bottom rod 65. And as the sliding frame 66 moves away, the compressed first spring 64 will rebound to drive the sealing plate 63 to move upward. At this time, the sealing plate 63 will move upward to fit with the top plate 43 to block the through hole 431. Then when the top plate 43 moves downward, the top plate 43 will squeeze the air inward. At this time, the air will flow out from the opening of the side baffle 41 of the training room 1, so as to facilitate the rapid removal of the combustion residues on the bottom plate 51. At the same time, when the bottom rod 65 approaches the chamfer at the bottom end of the sliding frame 66, the bottom rod 65 will push the sliding frame 66 to move outward, so that the bottom rod 65 moves to the bottom end of the sliding frame 66.

[0040] In another embodiment of the present invention: a square plate 67 is fixedly installed at the bottom end of the slide frame 66, and a second spring 68 is fixedly installed between the square plate 67 and the training room 1;

[0041] When the slide frame 66 moves outward, the second spring 68 will be stretched, and as the top plate 43 and the bottom rod 65 are removed, the second spring 68 will drive the slide frame 66 to slide inward and reset.

[0042] In another embodiment of the present invention: a slide bar 69 is fixedly mounted on the bottom end of the outer plate 61, and the slide bar 69 passes through the top plate 43;

[0043] The slide bar 69 is located on one side of the outer plate 61. When the top plate 43 rises and the closing plate 63 is restricted from moving by the slide frame 66, the slide bar 69 will move inside the top plate 43. At the same time, the slide bar 69 will make the outer plate 61, the connecting bar 62 and the closing plate 63 vertically slide and be installed on the top plate 43.

[0044] In another embodiment of the present invention: a limiting frame 54 is fixedly installed on the side wall of the training room 1, and a convex plate 55 is fixedly installed on the friction wheel 53;

[0045] The limit frame 54 is T-shaped and is located above the convex plate 55. When the bottom plate 51 rotates to a horizontal state, the limit frame 54 will be located above the convex plate 55 and press against the convex plate 55, so that the friction wheel 53 will not rotate, thereby keeping the bottom plate 51 horizontal. When the bottom plate 51 rotates upward, the convex plate 55 will move downward and away from the limit frame 54, thereby facilitating the rotation of the bottom plate 51. At the same time, the existence of the limit frame 54 ensures that after the firefighter enters the training room 1, stepping on the bottom plate 51 will not cause the bottom plate 51 to flip downward.

[0046] In another embodiment of the present invention: the ends of the two bottom plates 51 close to each other are both provided with avoidance bevel edges;

[0047] The bottom sides of the two bottom plates 51 close to one end are provided with avoidance bevel edges, so that the two bottom plates 51 will not interfere with each other when rotating, thereby facilitating the two bottom plates 51 to open upwards.

[0048] In another embodiment of the present invention: a stopper 48 is fixedly installed at one end of the rotating shaft 44 located inside the training room 1, a support plate 49 is rotatably installed on the inner wall of the training room 1, and a wooden board 413 is arranged on the support plate 49;

[0049] In order to simulate the situation where sundries are likely to fall from the top of a fire scene, the wooden board 413 is placed on the support plates 49 located on both inner walls. After the wooden board 413 burns and breaks, it will fall to train the rescue personnel's prevention ability against falling objects from the top. During the training process, multiple wooden boards 413 are usually placed, so there is a possibility that the wooden board 413 does not completely burn and break. At this time, after the training ends, the wooden board 413 is still located on the support plate 49. When the rotating rod 45 is rotated to open the side baffle 41, the rotating shaft 44 will drive the abutting rod 48 to rotate. As the abutting rod 48 rotates, it will upwardly squeeze at one end of the bottom side of the support plate 49, so that the support plate 49 rotates. At this time, as the support plate 49 rotates, the incompletely burned template on it will fall off, and at the same time, it will break after falling, so as to facilitate the bottom plate 51 to rotate and pour it out.

[0050] In another embodiment of the present invention: One end of the support plate 49 is fixedly installed with a convex iron 411, and a magnet 412 is arranged at the bottom end of the convex iron 411. The magnet 412 is fixedly installed on the inner wall of the training room 1;

[0051] When the support plate 49 is in a horizontal state, the convex iron 411 on its side wall will be adsorbed by the magnet 412, so that the support plate 49 remains horizontal after placing a number of wooden boards 413. Until the abutting rod 48 jacks up the support plate 49 upward, the convex iron 411 will be separated from the magnet 412, so that the support plate 49 tilts.

[0052] In another embodiment of the present invention: The inner wall of the training room 1 is fixedly installed with a limiting strip 410;

[0053] The limiting strip 410 is located above the support plate 49. By the limiting strip 410, it is possible to prevent the support plate 49 from rotating significantly under the influence of gravity due to the falling off of the template after tilting, resulting in the overturning of the support plate 49. When the limiting strip 410 limits the rotation angle of the support plate 49, after the wooden board 413 falls, the support plate 49 will fall back and contact the magnet 412 to continue to maintain horizontal.

[0054] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
