[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figures 1 to 6 As shown:

[0027] Embodiment 1: The present invention provides a fire ventilation and smoke exhaust device, comprising: a ventilation pipe mechanism 1, comprising a ventilation pipe assembly 11, a set of guide assemblies 12 mounted on the ventilation pipe assembly 11, and a set of position limiting support assemblies 13 slidably engaged with the ventilation pipe assembly 11;

[0028] The smoke exhaust fan mechanism 2 includes a smoke exhaust fan assembly 21 that is slidably engaged with the ventilation pipe assembly 11 and a set of positioning assemblies 22 installed on the smoke exhaust fan assembly 21;

[0029] The ventilation duct assembly 11 includes a ventilation duct body 111. Slide grooves 112 are formed on both sides of the ventilation duct body 111. An inspection groove 113 is formed at the bottom of the ventilation duct body 111. A set of support rods 114 are fixedly connected to the bottom of the ventilation duct body 111 and on both sides of the inspection groove 113 through mounting blocks.

[0030] The smoke exhaust fan assembly 21 includes a smoke exhaust fan body 211 , both sides of the top of the smoke exhaust fan body 211 are fixedly connected with sliders 212 , the sliders 212 are slidably connected in the slide groove 112 , and the bottom of the smoke exhaust fan body 211 is fixedly connected with a sealing plate 213 matching the inspection groove 113 .

[0031] Specifically, a set of guide components 12 includes a sealing frame 121 fixedly connected to the outside of the ventilation pipe body 111, a guide rod 122 is fixedly connected to the inside of the sealing frame 121, and the slider 212 passes through the slide groove 112 and is slidably connected to the outside of the guide rod 122.

[0032] Specifically, a group of positioning components 22 includes positioning blocks 221 , each of which is provided with a positioning hole 222 , and a handle is fixedly connected between the positioning blocks 221 .

[0033] As can be seen from the above, when the smoke exhaust fan body 211 needs to be inspected, the limiting effect of the limit support assembly 13 on the positioning assembly 22 is first released. At this time, the smoke exhaust fan body 211 moves steadily downward along the guide rod 122 through the slider 212 under the action of its own gravity. At this time, the smoke exhaust fan body 211 is supported and embedded in the bottom of the ventilation pipe body 111 by the slider 212. There is no need to completely remove the smoke exhaust fan body 211 from the ventilation pipe body 111, making the maintenance process faster and more convenient, reducing the time and effort required for disassembly and reinstallation, and improving maintenance efficiency. After the maintenance is completed, hold the handle and push the smoke exhaust fan body 211 upward to the inside of the ventilation pipe body 111 until the sealing plate 213 seals the inspection groove 113, and then limit the positioning assembly 22 through the limit support assembly 13, so that the smoke exhaust fan body 211 is always located inside the ventilation pipe body 111, providing reliable protection for subsequent ventilation and smoke exhaust work.

[0034] Example 2: This example is basically the same as the previous example, except that a set of limit support assemblies 13 includes a spring 131 and a connecting plate 132 slidably connected to the outside of the support rod 114, and a set of limit blocks 133 matching the positioning holes 222 are fixedly connected to the connecting plate 132.

[0035] Specifically, a support plate 134 is fixedly connected to the connecting plate 132 and located between a group of limiting blocks 133 .

[0036] Specifically, the spring 131 can drive the limiting block 133 on the connecting plate 132 to be embedded in the positioning hole 222 , and the supporting plate 134 can support the sealing plate 213 .

[0037] At the same time, the support plate 134 on the connecting plate 132 moves to the bottom of the sealing plate 213 to support the sealing plate 213, effectively preventing the smoke exhaust fan body 211 from being separated from the ventilation pipe body 111 due to accidental factors, thereby enhancing the safety and stability of the system.

[0038] Application Process:

[0039] Normal State: The fire ventilation and smoke exhaust system is in normal operation. The smoke exhaust fan assembly 21 is securely mounted on the slide slot 112 and guide rod 122 of the ventilation duct assembly 11 via the slider 212. At this point, the spring 131 of the position-limiting support assembly 13 is in its natural position, and the position-limiting block 133 engages the positioning hole 222 of the positioning block 221, ensuring that the smoke exhaust fan body 211 remains securely in place. The support plate 134 rests beneath the sealing plate 213, maintaining the seal of the system.

[0040] Maintenance requirements: When smoke exhaust fan body 211 needs to be repaired, maintenance personnel first move connecting plates 132 away from each other, compressing spring 131. Simultaneously, stop block 133 disengages from positioning hole 222, and support plate 134 moves accordingly, no longer supporting sealing plate 213. At this point, smoke exhaust fan body 211, under its own weight, slides smoothly along guide rod 122 to the bottom inspection slot 113 of ventilation duct body 111, eliminating the need for complete disassembly, making the repair process quick and convenient.

[0041] Maintenance process: After the smoke exhaust fan body 211 arrives at the maintenance position, maintenance personnel can directly perform operations such as inspection, cleaning or replacement of parts on it.

[0042] Maintenance Completed: After the maintenance is complete, the maintenance personnel grasp the handle on the positioning block 221 and push the smoke exhaust fan body 211 upward along the guide rod 122 back into the interior of the ventilation duct body 111 until the sealing plate 213 re-engages the inspection slot 113. At this point, the spring 131 regains its deformation, pushing the stop block 133 on the connecting plate 132 back into the positioning hole 222, securing the smoke exhaust fan body 211. Simultaneously, the support plate 134 moves below the sealing plate 213, providing additional support and ensuring that the smoke exhaust fan body 211 remains secure and does not fall off.
