[0026] As Figures 1-7 shown, the multi-layer frame type re-burning fire basin for the intelligent campus fire drill comprises a support frame 1, a bearing seat 12, a fixed table 4, a pulley 62, a sliding sleeve 71, a pedal 41, a waste box 5, a transverse moving frame 6 and a longitudinal moving frame 7, the transverse moving frame 6 is slidingly installed in the longitudinal moving frame 7, the longitudinal moving frame 7 is nested in the support frame 1, and the three are lifted and moved through the cooperation of the pulley 62 and the sliding sleeve 71; the pedal 41 is hingedly connected to the end of the fixed table 4; the support frame 1 side is provided with the bearing seat 12, the fixed shaft 13, the gear set 3, the chain 21 and the chain tooth 2, the support frame 1 side is symmetrically provided with the bearing seat 12, the fixed shaft 13 penetrates through the bearing seat 12, the fixed shaft 13 is sleeved with the chain tooth 2 at both ends, and the chain 21 is wound outside the chain tooth 2 and connected with the bottom of the longitudinal moving frame 7; the gear set 3 is installed at the hinged position of the fixed shaft 13 and the pedal 41, and the gear set 3 is synchronously rotated by driving the fixed shaft 13 to rotate through the rotation of the pedal 41; the transverse moving frame 6 side is provided with the rotating shaft 9, the coil spring 92, the connecting rod 94 and the rotating disc 93, the coil spring 92 is sleeved on the rotating shaft 9, and the rotating shaft 9 is movably connected with the transverse moving frame 6 through the connecting rod 94 and the rotating disc 93 at the tail end; the waste box 5 is respectively provided with the primary air inlet 51 and the air guide 52 at both sides, and the bottom is provided with the secondary air inlet 53.

[0027] In this embodiment, the fixed platform 4 is provided with an air inlet pipe 54 on its side, and the waste box 5 is placed at the bottom of the support frame 1 for collecting combustion residues. The secondary air inlet 53 on one side is connected to the outside, and the primary air inlet 51 is connected to the air guide port 52. The gases flowing into the secondary air inlet 53 and the primary air inlet 51 respectively converge into the air guide port 52.

[0028] In this embodiment, the air inlet 52 has a funnel-shaped structure that is inclined towards the filter screen 61, and the secondary air inlet 53 and the primary air inlet 51 are intersected in an "in" shape.

[0029] In this embodiment, the connecting rod 94 is hinged to the turntable 93, and the connecting rod 94 is installed off-center from the turntable 93, so that when the turntable 93 rotates, it drives the transverse moving frame 6 to reciprocate along the track of the pulley 62 through the connecting rod 94.

[0030] In this embodiment, a rubber ring 42 is provided below the pedal 41, and an air exchange port 44 is opened on the fixed platform 4. The air exchange port 44 is connected to the air chamber 45. The secondary air inlet 53 is connected to the air chamber 45 through the air inlet pipe 54. When the rubber ring 42 is pressed down by the pedal 41, it deforms and rebounds, pushing air into the air chamber 45 through the air exchange port 44.

[0031] In this embodiment, the pulleys 62 are staggered and interlocked at the bottom of the longitudinal moving frame 7.

[0032] In this embodiment, the side wall of the transverse moving frame 6 is provided with a heat insulation frame 8 to prevent the flame from directly contacting the side wall of the longitudinal moving frame 7 and the support frame 1.

[0033] In this embodiment, a filter screen 61 is provided on the lower surface of the transverse moving frame 6.

[0034] In this embodiment, the upper surface of the foot pedal 41 is provided with an anti-slip strip 43 to enhance the friction of the foot during operation.

[0035] In this embodiment, the fixed shaft 13 can drive the chain teeth 2 to rotate during rotation, thereby causing the chain 21 to pull the longitudinal moving frame 7 up and down along the support frame 1.

[0036] When in use, the operator places the flammable material for the exercise on the filter screen 61 inside the horizontal moving frame 6. Then, the students in the exercise take the fire extinguisher, stand on it, step on the pedal 41, and turn on the fire extinguisher to extinguish the fire on the flammable material on the filter screen 61.

[0037] When a student stands on the foot pedal 41, during the pressing of the foot pedal 41, the gear set 3 at its hinge drives the fixed shaft 13 to rotate. The chain teeth 2 at both ends of the fixed shaft 13 rotate together, causing the chain 21 wrapped around the outside of the chain teeth 2 to pull the longitudinal moving frame 7 down along the support frame 1, thereby causing the transverse moving frame 6 and the combustibles inside to fall onto the surface of the waste box 5. At this moment, because the combustibles are flush with the surface of the waste box 5, they lack oxygen to enter the filter screen 61, and the combustion intensity gradually weakens, thus making it easier for the students to extinguish the fire during the drill.

[0038] At the same time, the rubber ring 42 under the pedal 41 is compressed and deformed. The rubber ring 42 pushes air into the air chamber 45 through the air exchange port 44. The air in the air chamber 45 is transported to the primary air inlet 51 of the waste box 5 through the air inlet pipe 54. Under the guidance of the primary air inlet 51 and the air guide port 52, a directional airflow is formed. The air is then sprayed out obliquely through the trumpet-shaped air guide port 52, further disturbing the airflow in the combustion area, simulating the complex wind conditions in a real fire, and enhancing the realism of the fire extinguishing drill.

[0039] After the student finishes extinguishing the fire and leaves, when the foot releases the pedal 41, the rubber ring 42 rebounds; at this moment, the longitudinal moving frame 7 returns to its original position and rises, so that air enters from the gap between the filter screen 61 and the waste box 5 and enters below the filter screen 61. The burning material reignites due to the supply of oxygen, thus facilitating the next student's drill.

[0040] In addition, during the lifting and lowering of the longitudinal moving frame 7, turning the handle 91 can rotate the shaft 9, and the coil spring 92 will be stressed and stored. The turntable 93 at the end of the shaft 9 drives the transverse moving frame 6 to reciprocate along the track of the pulley 62 through the connecting rod 94. This causes the combustibles on the filter screen 61 to swing synchronously with the transverse moving frame 6 during the burning process. The extinguishing agent covering the combustibles is dislodged under the shaking, so that when the next student conducts a fire extinguishing drill, the combustibles can quickly reignite, thereby improving the continuity of the drill.

[0041] The entire operation requires no external power source, has a compact structure and is easy to operate. It can also simulate reignition in real fire scenarios and meet the practical training needs of fire drills in smart campuses.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
