[0036] Refer to Figures 1 to 10 , which is the first embodiment of the present invention, providing a detection method based on fire protection engineering facilities to achieve multi-angle and precise detection of smoke alarms.

[0037] First, spray the smoke into the smoke hood 102 through the cigarette nozzle 303, and then achieve the alarm detection in different wind directions through the operation of the motor 212c; Through the setting of the arc-shaped component 201, when the motor 212c operates, it can move along the arc-shaped groove 201b, the first guide groove 204, and the second guide groove 210 by using the second gear 212b, and at the same time drive the blowing component 202 to blow air, achieving the alarm detection in different wind directions.

[0038] Specifically, start the smoke generator 103, spray the simulated smoke into the smoke hood 102 through the cigarette nozzle 303 to cover the smoke alarm to be detected; Turn on the motor 212c, use the connecting shaft 212a to drive the second gear 212b to roll along the arc-shaped rack 203, and at the same time the limiting block 212d slides in the arc-shaped groove 201b to ensure that the motor 212c moves stably along the arc-shaped trajectory; When the second gear 212b moves, it drives the cigarette nozzle 303 to make a circular motion along the arc-shaped groove 201b, the first guide groove 204, and the second guide groove 210, realizing multi-angle smoke spraying. At the same time, the limiting rod 307 moves to push the two side tooth plates 208, and through the transmission of the stroke rod 206 and the tooth plate 208 and the first gear 202d, the fan blade 202c rotates to generate wind power; The limiting rod 307 at the top of the connecting rod 302 is simultaneously squeezed by the toothed plate 208 during the movement process, pushing the blocking rod 308 to gradually block the cigarette spraying head 303, changing the outlet opening of the cigarette spraying head 303, automatically increasing or decreasing the cigarette spraying amount, and simulating the smoke concentration problem in a fire; Observe the alarm response of the smoke alarm under different smoke paths, wind interference and concentration changes to complete the detection. Embodiment 2

[0039] Refer to Figures 1 to 10 , which is the second embodiment of the present invention, provides a simulation mechanism 200 to simulate the complex interaction scenario of smoke and air flow in a fire.

[0040] A support mechanism 100, which includes a support rod 101, a smoke hood 102 is fixedly connected to the top of the support rod 101, and a smoke generator 103 is arranged inside the support rod 101; A simulation mechanism 200, which includes an arc-shaped component 201 arranged inside the smoke hood 102, and blowing components 202 are arranged on both the left and right sides of the arc-shaped component 201; Among them, the arc-shaped component 201 includes a plurality of arc-shaped rods 201a arranged inside the smoke hood 102. The plurality of arc-shaped rods 201a are arranged in a circular distribution inside the smoke hood 102. An arc-shaped groove 201b is formed on the surface of the arc-shaped rod 201a. The outside of the arc-shaped groove 201b extends to the inside of the smoke hood 102. A support block 201c is arranged outside the arc-shaped rod 201a, and the outside of the support block 201c is fixedly connected to the inside of the smoke hood 102; The blowing component 202 includes arc-shaped plates 202a arranged on both the left and right sides of the arc-shaped rod 201a. A rotating column 202b is arranged on the right side of the arc-shaped plate 202a. A fan blade 202c is arranged on the right side of the rotating column 202b. A first gear 202d is arranged outside the rotating column 202b; An arc-shaped toothed rod 203 is fixedly connected to the inside of the arc-shaped rod 201a. A first guide groove 204 is formed on the left side of the arc-shaped toothed rod 203. The first guide groove 204 is communicated with the arc-shaped groove 201b; A travel groove 205 is formed on the right side of the arc-shaped plate 202a. A travel rod 206 is slidably connected to the surface of the travel groove 205. A tension spring 207 is arranged on the top of the travel rod 206. The top of the tension spring 207 is fixedly connected to the inside of the travel groove 205. A toothed plate 208 is arranged on the right side of the travel rod 206. The surface of the toothed plate 208 is meshed with the surface of the first gear 202d; Connecting plates 209 are fixedly connected to the opposite sides of the plurality of arc-shaped rods 201a. Second guide grooves 210 are formed on both the upper and lower sides of the connecting plates 209. The second guide grooves 210 are communicated with the arc-shaped grooves 201b. A transmission component 212 is arranged on the surface of the second guide grooves 210; Among them, a fixing seat 211 is provided at the bottom of the connecting plate 209, and the bottom of the fixing seat 211 is fixedly connected to the inner side of the smoke hood 102; The transmission component 212 includes a connecting shaft 212a disposed on the surface of the second guiding groove 210. A second gear 212b is provided at the top of the connecting shaft 212a. The surface of the second gear 212b meshes with the surface of the arc-shaped tooth bar 203. A motor 212c for transmission is provided at the bottom of the connecting shaft 212a. A limiting block 212d is fixedly connected to the bottom of the motor 212c. The outer side of the limiting block 212d is slidably connected to the inner side of the arc-shaped groove 201b.

[0041] Specifically, through the setting of the arc-shaped assembly 201, the motor 212c can move along the track of the arc-shaped groove 201b during operation. Four groups of arc-shaped assemblies 201 are provided, and the middle parts of each group are connected by a connecting plate 209, so that the motor 212c can move to different positions through the arc-shaped groove 201b, the first guiding groove 204 and the second guiding groove 210.

[0042] Further, by starting the motor 212c, the connecting shaft 212a is driven to rotate. The second gear 212b at the top of the connecting shaft 212a meshes with the arc-shaped tooth bar 203 fixed to the inner side of the arc-shaped rod 201a. Since the arc-shaped tooth bar 203 is fixed to the inner side of the smoke hood 102, the second gear 212b rolls along the circumferential track of the arc-shaped tooth bar 203 during rotation. At the same time, the limiting block 212d at the bottom of the motor 212c slides in the arc-shaped groove 201b (the arc-shaped groove 201b is the arc-shaped groove 201b opened on the inner side of the smoke hood 102). The arc-shaped groove 201b is communicated with the first guiding groove 204 and the second guiding groove 210, providing a track constraint for the movement of the motor 212c. The cooperation between the limiting block 212d and the arc-shaped groove 201b ensures that the motor 212c will not shift or shake during the movement, so that the connecting shaft 212a can move stably along the preset arc path.

[0043] Preferably, when the second gear 212b rolls along the arc-shaped rack 203 to drive the connecting rod 302 and the cigarette lighter head 303 to move, since the height of the limiting rod 307 is higher than that of the arc-shaped rod 201a, when the second gear 212b moves along the track of the arc-shaped groove 201b, it will squeeze the bottom or top of the toothed plate 208. When the toothed plate 208 is squeezed, it pushes the stroke rod 206 to move in the stroke groove 205, and then the tension spring 207 is compressed. When the toothed plate 208 moves, it will mesh with the first gear 202d on the outside of the rotating column 202b. The linear motion of the toothed plate 208 is converted into the rotation of the first gear 202d through meshing. The first gear 202d drives the rotating column 202b and the fan blade 202c on the right side to rotate slowly, generating simulated wind force (slow wind); since the stroke groove 205 is obliquely arranged, the toothed plate 208 gradually moves away from the limiting rod 307 until it disengages under the action of the stroke groove 205 after being squeezed. Since the tension spring 207 is compressed when the toothed plate 208 is squeezed, the elastic force of the tension spring 207 will be released when the toothed plate 208 disengages from the surface of the limiting rod 307, so that the toothed plate 208 meshes with the first gear 202d again for transmission, and the first gear 202d drives the rotating column 202b and the fan blade 202c on the right side to rotate quickly, generating simulated wind force (fast wind); simulating the interference of airflows with different speeds in a fire scene on the smoke.

[0044] It should be noted that one end of the cigarette lighter head 303 connected to the connecting rod 302 is in a telescopic state. Embodiment 3

[0045] Refer to Figures 2 to 5 Figures 9 and 10, which are the third embodiment of the present invention, provide a pressing block 305, a limiting rod 307 and a blocking rod 308 to simulate the dynamic change process of the smoke concentration affected by the airflow in a fire and improve the detection authenticity.

[0046] A fixing column 301 is arranged on the top of the second gear 212b. A connecting rod 302 is sleeved outside the fixing column 301. The inner side of the connecting rod 302 is fixedly connected with a cigarette lighter head 303. The bottom of the cigarette lighter head 303 penetrates through the bottom of the connecting plate 209 and is connected to the smoke spraying end of the smoke generator 103 in a communicating manner; An extrusion groove 304 is formed on the top of the connecting rod 302. A pressing block 305 is slidably connected to the surface of the extrusion groove 304. The right side of the pressing block 305 is fixedly connected with a pressing spring 306. The right side of the pressing spring 306 is fixedly connected to the inner side of the extrusion groove 304; The top of the pressing block 305 is fixedly connected with a limiting rod 307. A blocking rod 308 is fixedly connected to the right side of the pressing block 305. The blocking rod 308 is used to block the cigarette lighter head 303. The bottom of the limiting rod 307 is higher than the top of the arc-shaped rod 201a.

[0047] Specifically, through the settings of the extrusion block 305, the limiting rod 307, and the blocking rod 308, the positions of the limiting rod 307 and the blocking rod 308 change when the second gear 212b moves, thereby realizing the adjustment of the smoke emission amount of the cigarette lighter 303.

[0048] Furthermore, a connecting rod 302 is sleeved on a fixing column 301 provided at the top of the second gear 212b. The cigarette lighter 303 fixed to the inner side of the connecting rod 302 moves along with the movement of the second gear 212b. Under the guidance of the arc-shaped groove 201b, the first guiding groove 204, and the second guiding groove 210, it moves in a circular or arc-shaped trajectory along the inner side of the smoke hood 102. During this process, since the bottom of the limiting rod 307 is fixedly connected to the top of the extrusion block 305, and the right side of the extrusion block 305 is fixedly connected to the blocking rod 308, when the limiting rod 307 is subjected to the relative extrusion force of the toothed plate 208, the blocking rod 308 will gradually block the nozzle of the cigarette lighter 303, thereby changing the smoke emission amount of the cigarette lighter 303 (the emitted smoke amount is blocked and thus becomes less); when the limiting rod 307 is separated from the toothed plate 208, the blocking rod 308, the limiting rod 307, and the extrusion block 305 will be reset under the action of the extrusion spring 306, so that the blocked state of the nozzle of the cigarette lighter 303 is released (the emitted smoke amount is released from the blocked state and thus becomes more), simulating the smoke emission amounts in different fire situations during a fire, or the situation where the smoke concentration in a fire changes with the airflow.

[0049] It should be noted that when the limiting rod 307 moves upward along the arc-shaped groove 201b, the smoke amount becomes less; conversely, when the limiting rod 307 moves downward along the arc-shaped groove 201b, the smoke amount becomes more. When the limiting rod 307 moves downward along the arc-shaped groove 201b, the direction of squeezing the toothed plate 208 changes, so the extrusion block 305 will not move along the extrusion groove 304.

[0050] The remaining structure is the same as that of Embodiment 2. Embodiment 4

[0051] Refer to Figures 1 to 10 , which is the fourth embodiment of the present invention. The difference between this embodiment and the third embodiment is that this embodiment provides a detection device based on fire protection engineering facilities.

[0052] When using this detection device; First, place the smoke detector to be detected in the smoke hood 102. The smoke generator 103 inside the support rod 101 serves as a smoke source and is connected to the cigarette lighter 303 through a pipeline. Start the smoke generator 103 to simulate that the smoke is sprayed into the smoke hood 102 through the cigarette lighter 303 to initially cover the detector. When simulating the sensitivity of the smoke detector in different scenarios; By starting the motor 212c, the connecting shaft 212a is driven to rotate. The second gear 212b at the top of the connecting shaft 212a meshes with the arc-shaped rack 203 fixed to the inner side of the arc-shaped rod 201a. Since the arc-shaped rack 203 is fixed to the inner side of the hood 102, the second gear 212b rolls along the circumferential trajectory of the arc-shaped rack 203 during rotation. At the same time, the limiting block 212d at the bottom of the motor 212c slides in the arc-shaped groove 201b (the arc-shaped groove 201b is the arc-shaped groove 201b opened on the inner side of the hood 102). The arc-shaped groove 201b is connected to the first guiding groove 204 and the second guiding groove 210, providing trajectory constraints for the movement of the motor 212c. The cooperation between the limiting block 212d and the arc-shaped groove 201b ensures that the motor 212c does not shift or shake during movement, enabling the connecting shaft 212a to move stably along the preset arc path; When the second gear 212b rolls along the arc-shaped rack 203 to drive the connecting rod 302 and the cigarette spraying head 303 to move, since the height of the limiting rod 307 is higher than the height of the arc-shaped rod 201a, when the second gear 212b moves along the trajectory of the arc-shaped groove 201b, it will squeeze the bottom or top of the toothed plate 208. When the toothed plate 208 is squeezed, it pushes the stroke rod 206, causing it to move in the stroke groove 205. As a result, the tension spring 207 is compressed. And when the toothed plate 208 moves, it meshes and drives with the first gear 202d on the outer side of the rotating column 202b. The linear motion of the toothed plate 208 is converted into the rotation of the first gear 202d through meshing. The first gear 202d drives the rotating column 202b and the fan blade 202c on the right side to rotate slowly, generating simulated wind force (slow wind); Since the stroke groove 205 is obliquely arranged, when the toothed plate 208 is squeezed, it gradually moves away from the limiting rod 307 under the action of the stroke groove 205 until it disengages. Since the tension spring 207 is compressed when the toothed plate 208 is squeezed, when the toothed plate 208 disengages from the surface of the limiting rod 307, the elastic force of the tension spring 207 will be released, causing the toothed plate 208 to mesh and drive with the first gear 202d again, enabling the first gear 202d to drive the rotating column 202b and the fan blade 202c on the right side to rotate quickly, generating simulated wind force (fast wind); simulating the interference of airflows at different speeds in a fire scene on the smoke; The fixed post 301 arranged at the top of the second gear 212b is sleeved with a connecting rod 302. The cigarette spraying head 303 fixed inside the connecting rod 302 moves along the inner side of the cigarette hood 102 in a circular or arc trajectory under the guidance of the arc-shaped groove 201b, the first guiding groove 204 and the second guiding groove 210 as the second gear 212b moves. During this process, since the bottom of the limiting rod 307 is fixedly connected to the top of the extrusion block 305, and the right side of the extrusion block 305 is fixedly connected to the blocking rod 308, when the limiting rod 307 is subjected to the relative extrusion force of the toothed plate 208, the blocking rod 308 will gradually block the spraying port of the cigarette spraying head 303, so that the cigarette spraying amount of the cigarette spraying head 303 changes (the sprayed smoke amount is blocked, so it becomes less). When the limiting rod 307 is separated from the toothed plate 208, the blocking rod 308, the limiting rod 307 and the extrusion block 305 will be reset under the action of the compression spring 306, so that the blocking state of the spraying port of the cigarette spraying head 303 is released (the sprayed smoke amount is released from the blocking state, so it becomes more), simulating the smoke emission amount in different fire situations during a fire, or the situation where the smoke concentration in a fire changes with the airflow.

[0053] In summary: Through the design of the support mechanism 100 and the simulation mechanism 200, complex and changeable fire field situations can be simulated, effectively avoiding false alarms or missed alarms caused by smoke direction, wind interference and concentration changes, and greatly improving the reliability and effectiveness of the detection of fire protection engineering facilities.
