[0033] Embodiment 1

[0034] like Figure 1 As shown, the fire smoke exhaust fan air duct docking mechanism provided by the embodiment of the present invention includes: an air guide component 100 and a drive component 200; the drive component 200 is transmission-connected to the air guide component 100, and the drive component 200 is used to drive the air guide component 100 to connect or disconnect the smoke and dust duct 400 with the fluid of the wind source device 300.

[0035] Specifically, the driving component 200 can drive the air guide component 100 and connect or disconnect the smoke and dust pipe 400 with the air source device 300. Not only can the self-suction smoke exhaust mode be switched to the air supply smoke exhaust mode, but also the self-air supply smoke exhaust mode can be switched to the suction smoke exhaust mode. There is no need to arrange two kinds of smoke exhaust devices at the fire scene or call two smoke exhaust fire trucks, which can improve the utilization rate of fire fighting resources, shorten the deployment time of smoke exhaust devices, and improve fire fighting efficiency.

[0036] In an embodiment of the present invention, the air guide assembly 100 includes an air guide sleeve, which is connected to the driving assembly 200; in the docking state, the opening of the air guide sleeve faces the air inlet of the wind source device 300; in the avoidance state, the air guide sleeve avoids the air inlet of the wind source device 300.

[0037] Specifically, the driving assembly 200 can drive the air guide sleeve to swing, and the air guide sleeve rotates around a straight line perpendicular to its own axis; or, the air guide sleeve swings around a position parallel to its own axis and spaced from its own axis. The air guide sleeve can move from the air inlet avoiding the wind source device 300 to the air inlet facing the wind source device 300, or from the air inlet facing the wind source device 300 to the air inlet avoiding the wind source device 300 by swinging.

[0038] Furthermore, the air guide assembly 100 also includes a bellows, one end of the bellows is connected to the smoke and dust pipe 400, and the other end of the bellows is connected to the air guide sleeve; in the avoidance state, the bellows shrinks between the smoke and dust pipe 400 and the air guide sleeve.

[0039] Specifically, when the air guide sleeve avoids the air inlet of the wind source device 300 , the bellows can be folded and contracted between the smoke duct 400 and the air guide sleeve so that the air guide sleeve moves toward the smoke duct 400 to avoid the air inlet of the wind source device 300 .

[0040] Furthermore, the opening area of ​​the air guide sleeve increases gradually from the end connected to the bellows to the end away from the bellows.

[0041] Specifically, the end of the air guide sleeve facing away from the bellows has a larger opening. When the air guide sleeve is facing the wind source device 300, under the suction action of the wind source device 300, the airflow enters the wind source device 300 from the smoke and dust pipeline 400 through the bellows and the air guide sleeve, and is discharged from the side of the wind source device 300 facing away from the air guide sleeve.

[0042] Furthermore, the driving assembly 200 includes: a power element 210 and a support member 220 connected to the power element 210; the support member 220 is connected to the air guide assembly 100 to drive the air guide assembly 100 to rise, fall and flip.

[0043] In some embodiments, the power element 210 includes a motor, and the support member 220 includes a swing rod, one end of the swing rod is connected to the transmission shaft of the motor and extends in a direction perpendicular to the transmission shaft, and the other end of the swing rod is connected to the air guide sleeve, and the swing rod is driven by the motor to swing, so that the air guide sleeve is directed toward the air inlet of the wind source device 300 or the air guide sleeve avoids the air inlet of the wind source device 300. It should be noted that in the process of the air guide assembly 100 moving from avoiding the air inlet of the wind source device 300 to the air inlet toward the wind source device 300, the air guide sleeve flips from bottom to top. In the air supply state, the air guide sleeve flips downward and compresses the bellows, so that the air guide assembly 100 can be fully contracted to prevent the air guide assembly 100 from obstructing the air intake of the wind source device 300, and improve the stability of the air guide assembly 100 in the air supply state.

[0044] In this embodiment, the support member 220 includes: a first rod 221, a second rod 222, a third rod 223 and a fourth rod 224; one end of the first rod 221 is slidably connected to the base 500 through a first hinge shaft, one end of the second rod 222 is hinged to the base 500, and the middle part of the first rod 221 is hinged to the middle part of the second rod 222; the other end of the first rod 221 is hinged to one end of the fourth rod 224, one end of the third rod 223 is hinged to the other end of the fourth rod 224, and the other end of the third rod 223 is hinged to the other end of the second rod 222; the fourth rod 224 is connected to the air guide assembly 100, and the power element 210 is used to drive the first rod 221 to adjust the angle between the first rod 221 and the second rod 222.

[0045] Specifically, the power element 210 includes a hydraulic cylinder, a fixed end of the hydraulic cylinder is connected to the base 500, and a movable end of the hydraulic cylinder is connected to the lower end of the first rod 221. Through the extension and retraction of the hydraulic cylinder, the first rod 221 can be made to perform a shearing motion relative to the second rod 222, thereby adjusting the support height of the support member 220 to the air guide assembly 100. When the hydraulic cylinder is retracted, the support height of the support member 220 to the air guide assembly 100 is increased, and the angle between the third rod 223 and the fourth rod 224 is reduced, further increasing the support height of the air guide assembly 100. While the support height is increased, the fourth rod 224 flips and drives the air guide sleeve so that the air guide sleeve faces the air inlet of the wind source device 300. When the hydraulic cylinder is extended, the support height of the support member 220 to the air guide assembly 100 is reduced, and the fourth rod 224 swings and drives the air guide sleeve to approach the smoke and dust pipeline 400, thereby compressing the bellows between the air guide sleeve and the smoke and dust pipeline 400. The support member 220 drives the air guide assembly 100 to rise and fall and flip through shearing motion, which can save the layout space of the fire smoke exhaust fan air duct docking mechanism, and improve the support stability through the angle formed between the connected rods. There are two drive assemblies 200, and the two drive assemblies 200 are respectively connected to the two sides of the air guide sleeve, and the stability of the air guide assembly 100 is ensured by the two drive assemblies 200.

[0046] Furthermore, the top of the fourth rod 224 is connected to the second hinge shaft, and the third rod 223 is hinged to the fourth rod 224 via the second hinge shaft. The second hinge shaft is fixedly connected to the fourth rod 224, and the second hinge shaft is fixedly connected to the air guide sleeve, so that the air guide sleeve can swing with the fourth rod 224, so that the air guide sleeve is directed toward or avoids the air inlet of the wind source device 300.

[0047] Furthermore, the smoke and dust pipeline 400 includes a pipe connection box, and the base 500 is connected to the top of the pipe connection box. The base 500 is provided with a slide groove, and the first hinge shaft is slidably connected in the slide groove. The power element 210 can drive the first hinge shaft to move along the slide groove and drive the first rod 221 to adjust the angle between the first rod 221 and the second rod 222, thereby adjusting the air guide assembly 100 to flip while lifting.

[0048] Embodiment 2

[0049] like Figure 1 and Figure 2 As shown, the smoke exhaust fire fighting device provided in the embodiment of the present invention comprises: an air source device 300, a smoke and dust pipeline 400 and the fire fighting smoke exhaust machine air duct docking mechanism provided in the second embodiment.

[0050] Specifically, the smoke and dust pipeline 400 includes a pipe connection box, and the smoke and dust pipe is detachably connected to the pipe connection box. When the air guide component 100 connects the wind source device 300 with the smoke and dust pipeline 400, the wind source device 300 can drive the airflow from the smoke and dust pipeline 400 to flow through the air guide component 100 into the wind source device 300, and be discharged from the side of the wind source device 300 away from the air guide component 100, thereby achieving suction and smoke exhaust. When the driving component 200 drives the air guide component 100 and disconnects the wind source device 300 from the smoke and dust pipeline 400, the wind source device 300 can guide the airflow to blow toward the fire scene, thereby achieving air supply and smoke exhaust.

[0051] In the embodiment of the present invention, the smoke exhaust fire fighting device has an air supply state and a suction state; in the air supply state, the driving component 200 drives the air guide component 100 and makes the air guide component 100 avoid the air inlet of the wind source device 300; in the suction state, the driving component 200 drives the air guide component 100 and makes the air guide component 100 connect the wind source device 300 with the smoke and dust pipeline 400. The smoke and dust pipeline 400 can be connected or disconnected with the wind source device 300 fluid through the fire smoke exhaust machine air duct docking mechanism, so that the smoke exhaust fire fighting device has the functions of suction and smoke exhaust and air supply and smoke exhaust, and there is no need to arrange two kinds of smoke exhaust devices at the fire scene or call two smoke exhaust fire trucks, which is convenient for shortening the deployment time of the smoke exhaust device and can improve the fire fighting efficiency.

[0052] Furthermore, a filter 310 is provided at the air inlet of the wind source device 300 .

[0053] Specifically, the filter 310 is made of metal to ensure strength. When supplying air and exhausting smoke, the filter 310 blocks particulate matter from entering the fire scene. In addition, the filter 310 can prevent debris from entering the wind source device 300, and prevent the wind source device 300 from being clogged by debris.
