Description

Technical Field

[0001] The invention relates to the technical field of fire simulation training, and in particular to a Class A material (wood) backfire training device. Background Art

[0002] Class A fires are fires involving solid materials. These fires usually involve solid materials such as hay, wood, cotton, wool, linen, paper, etc., which produce glowing embers when burned. Backdraft refers to the phenomenon that when the room is poorly ventilated and the combustion is in an oxygen-deficient state, the introduction of oxygen causes the hot smoke to burn explosively or rapidly.

[0003] After a fire occurs, different fire scenes are likely to cause different situations, especially backdraft. Since some firefighters have just joined the team or cannot intuitively feel the backdraft and other situations, they are likely to misjudge during disaster relief and get injured. Therefore, training devices are usually needed to enable firefighters to more intuitively feel the fire scene. Existing backdraft training devices usually burn combustibles such as wood during training to simulate the backdraft phenomenon for firefighters to train. After the training, burning residues will remain in the training room. In order to facilitate the next training, firefighters are usually required to enter to deal with ashes and other residues. However, since the training room usually simulates indoor conditions, it is relatively closed as a whole, so firefighters can only clean it bit by bit, resulting in a lot of effort to clean up after the training, which is time-consuming and laborious.

DETAILED DESCRIPTION

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

[0028] See also Figure 1-8 A Class A material (wood) backfire training device comprises a training room 1 and a door panel 3 fixedly mounted at the bottom thereof, the door panel 3 being rotatably mounted on the training room 1, and further comprising:

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

[0030] A connecting rod 42 is fixedly mounted above the side baffle 41, and a top plate 43 is fixedly mounted on the top of the connecting rod 42;

[0031] A rotating shaft 44 is rotatably mounted on the side wall of the training room 1, a rotating rod 45 is fixedly mounted on the rotating shaft 44, and long plates 46 are arranged at both ends of the rotating rod 45, one of the two long plates 46 is fixedly mounted on the side baffle 41, and the other is slidably mounted on the side wall of the training room 1;

[0032] A sealing plate 63 is vertically slidably mounted on the top plate 43, and a through hole 431 is formed on the top plate 43. The sealing plate 63 is used to seal the through hole 431;

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

[0034] When the rotating shaft 44 rotates, the side baffle 41 is driven to rise, and when the side baffle 41 rises, the bottom plate 51 is driven to rotate upward to pour out the burning materials in the training room 1. At the same time, when the rotating shaft 44 descends, the top plate 43 is driven to squeeze the air into the training room 1, so that the internal smoke and burning materials are quickly squeezed out from the side wall.

[0035] A base 2 is fixedly installed at the bottom of the training room 1, and the base 2 can facilitate the placement of the training room 1.

[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 a long board 46 slidably installed on the training room 1, and a plug rod 47 is fixedly installed on the surface of each long board 46, and rectangular slots are opened at both ends of the rotating rod 45;

[0037] When the training is over, ashes of the burning materials will remain in the training room 1. At this time, the electric push rod can be started, and 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 in the slot of the rotating rod 45 through the plug rod 47 on the surface to drive the rotating rod 45 to rotate with the help 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 of 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 on the top of the sealing plate 63, an outer plate 61 is fixedly installed on the top of the connecting strip 62, 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 on 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 both ends of the sliding block are provided with chamfers, and a first spring 64 is fixedly installed between the outer plate 61 and the top plate 43;

[0039] Among them, reference Figure 3-4 When the side baffle 41 rises, the top plate 43 will be driven 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 sealing plate 63 from rising. At this time, the through hole 431 will open. With the opening of the through hole 431, the smoke can flow out from the through hole 431. At the same time, when the top plate 43 moves to the chamfer near the top end of the sliding frame 66, the top plate 43 will contact the chamfer and squeeze the sliding frame 66 to make it move outward. At this time, the sliding frame 66 will move away from the surface of the bottom rod 65, and as the through hole 431 opens, the smoke can flow out from the through hole 431. When the slide frame 66 is moved away, the compressed first spring 64 will rebound to drive the closing plate 63 to move upward. At this time, the closing plate 63 will move up to fit the top plate 43 to block the through hole 431. Then, when the top plate 43 moves down, 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, thereby conveniently and quickly taking away 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 slide frame 66, the bottom rod 65 will push the slide frame 66 to move outward, thereby causing the bottom rod 65 to move to the bottom end of the slide 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 the bottom plate 51 will not flip downward when the firefighters step on the bottom plate 51 after entering the training room 1.

[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 debris is easily dropped from the top of a fire scene, wooden boards 413 are placed on support plates 49 located on the inner walls on both sides. After the wooden boards 413 burn and break, they will fall to train the rescue personnel's ability to prevent falling objects from the top. During the training process, multiple wooden boards 413 are usually placed, so there is a possibility that the wooden boards 413 will not completely burn and break. At this time, after the training, the wooden boards 413 are still located on the support plates 49, and when the rotating rod 45 is rotated to open the side baffle 41, the rotating shaft 44 will drive the push rod 48 to rotate. As the push rod 48 rotates, it will squeeze upward at one end of the bottom side of the support plate 49, thereby causing the support plate 49 to rotate. At this time, as the support plate 49 rotates, the incompletely burned template on it will fall off, and will break after falling, so that it is convenient for the bottom plate 51 to be rotated and poured out.

[0050] In another embodiment of the present invention: a convex iron 411 is fixedly mounted on one end of the support plate 49, and a magnet 412 is disposed at the bottom end of the convex iron 411, and the magnet 412 is fixedly mounted 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 attracted by the magnet 412, so that the support plate 49 remains horizontal after placing a number of wooden boards 413, until the support plate 49 is lifted upward by the support rod 48, the convex iron 411 will separate from the magnet 412, so that the support plate 49 tilts.

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

[0053] The limit bar 410 is located above the support plate 49. The limit bar 410 will prevent the support plate 49 from rotating significantly due to gravity and causing the support plate 49 to flip over after it tilts due to the falling of the template. After the limit bar 410 limits the rotation angle of the support plate 49, when the wooden board 413 falls, the support plate 49 will fall back and contact with the magnet 412 to continue to remain horizontal.

[0054] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
