Description

Technical Field

[0001] This utility model relates to the field of ventilation technology, specifically an integrated fire-fighting and smoke-exhausting ventilation device for underground garages. Background Technology

[0002] The integrated fire-fighting and smoke-exhausting ventilation device for underground parking garages is an intelligent device that combines ventilation and fire-fighting smoke exhaust. It consists of a fan, intelligent control module, and ductwork. Normally, it operates at low speed to maintain air quality. In case of fire, it is linked to the smoke detector to trigger high-speed smoke exhaust, which, together with the make-up air system, forms negative pressure smoke exhaust. It is widely used in underground parking garages in residential buildings, parking garages, and commercial complexes.

[0003] In existing technologies, ventilation ducts and fans are installed inside garages. The fans provide auxiliary ventilation through the ducts, reducing the settling of harmful gases. Some ventilation ducts are installed in the walls, and metal louvers are installed on the outside of the vents. When ventilation is in progress, the metal louvers open when blown and close when not blown, which can reduce the entry of small animals. However, the metal louvers are generally fixed to the vent position by a mounting frame. Disassembly requires disassembly of the entire unit. For example, if a blade is dusty, deformed, or damaged, it cannot be removed directly. It is necessary to remove adjacent blades or the entire vent, which cannot quickly repair local faults.

[0004] To address these issues, we offer an integrated fire-fighting, smoke extraction, and ventilation system for underground parking garages. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figure 1 - Figure 6As shown, this utility model provides a technical solution: an integrated fire-fighting, smoke exhaust, and ventilation device for a basement, including a base 1, with a ventilation duct assembly 2 and an exhaust duct assembly 3 installed inside the base 1. A ventilation slot 4 is provided inside the base 1. The basement is supported by a concrete structure. The ventilation duct assembly 2 and the exhaust duct assembly 3 are both controlled by an external fan and a control module, enabling air supply and exhaust to the interior of the basement.

[0032] An installation frame 5 is fixedly installed on the inner wall of the ventilation duct 4. A grille 16 is detachably connected to the inner wall of the ventilation duct 4. The grille 16 is located outside the installation frame 5. The grille 16 is installed outside the ventilation duct 4 to protect the ventilation duct 4 and reduce the entry of large foreign objects into the ventilation duct 4.

[0033] The mounting frame 5 has a positioning groove 6 inside. A partition plate 7 is fixedly installed on the inner wall of the positioning groove 6. An installation block 8 is slidably connected to the outer surface of the partition plate 7. A limit block 17 is fixedly installed on the outer surface of the partition plate 7. The limit block 17 has a T-shaped structure. The outer surface of the limit block 17 is slidably connected to the inside of the installation block 8. Multiple partition plates 7 divide the inside of the positioning groove 6 into multiple installation spaces. The T-shaped structure of the limit block 17 can reduce the shaking and displacement of the installation block 8 during use.

[0034] The mounting block 8 has a fixing hole 9 inside, and a mounting rod 10 is sleeved inside the fixing hole 9. A blade 11 is fixedly installed on the outer surface of the mounting rod 10. A limiting ring 18 is fixedly installed on the outer surface of the mounting rod 10. The outer surface of the limiting ring 18 is in contact with the outer surface of the mounting block 8. The limiting ring 18 is symmetrically arranged at both ends of the mounting rod 10. The two ends of the mounting rod 10 are limited by the limiting ring 18. The mounting rod 10 is connected to the inside of the fixing hole 9 through a support bearing. When fixing the blade 11, it is only necessary to rely on the two sets of mounting blocks 8 to limit and support the two ends of the mounting rod 10. When disassembling, it is only necessary to remove the mounting blocks 8 on both sides to replace or clean each set of blades 11 individually.

[0035] A fixing box 12 is slidably connected to the inner wall of the positioning groove 6. A wedge block 13 is slidably connected to the inner wall of the fixing box 12. A spring 14 is fixedly installed at one end of the wedge block 13. A positioning plate 19 is fixedly installed on the inner wall of the fixing box 12. A fixing cylinder 1 20 is fixedly installed on the outer surface of the positioning plate 19. A fixing cylinder 21 is slidably connected to the outer surface of the fixing cylinder 1 20. One end of the fixing cylinder 21 is fixedly installed on the outer surface of the wedge block 13. The spring 14 is sleeved on the outside of the fixing cylinder 1 20 and the fixing cylinder 2 21. The other end of the spring 14 is fixedly installed on the outer surface of the positioning plate 19. The fixing cylinder 1 20 and the fixing cylinder 2 21 can provide auxiliary support for the spring 14. At this time, the spring 14 can push the wedge block 13 to move outward of the fixing box 12. The spring 14 is made of high temperature resistant material and is suitable for use in garages with high temperature resistance.

[0036] One end of the wedge block 13 is provided with an inclined surface facing the outside of the mounting frame 5. The inner wall of the mounting frame 5 is provided with a positioning hole 22. The outer surface of the wedge block 13 is slidably connected to the inner wall of the positioning hole 22. The wedge block 13 enters the interior of the positioning hole 22 under the push of the spring 14. The thickness of the wedge block 13 is greater than the width of the positioning hole 22. Therefore, the wedge block 13 has a tendency to move in the opposite direction of the inclined surface after entering the interior of the positioning hole 22.

[0037] A push block 15 is fixedly installed on the outer surface of the fixing box 12. One end of the push block 15 contacts one side of the mounting block 8. The wedge block 13 is pushed by the spring 14 to squeeze the mounting block 8. The push block 15 and the mounting block 8 are pressed against each other. The wedge block 13 is pushed by the spring 14 to control the fixing box 12 to move into the mounting frame 5. At this time, one end of the push block 15 contacts the outer surface of the mounting block 8 and continues to press against it. With the limiting effect of the limiting block 17, the mounting block 8 can be stably fixed inside the mounting frame 5.

[0038] Working principle: When replacing blade 11, remove the fixing box 12. After removing the mounting block 8, the mounting rod 10 can be removed, allowing individual blade 11 to be disassembled and replaced. During installation, insert the mounting rod 10 into the interior of the mounting blocks 8 on both sides, and then push the mounting block 8 from the outside of the limiting block 17 to install the fixing box 12 inside the mounting frame 5. Under the push of the spring 14, the wedge block 13 enters the interior of the positioning hole 22. At this time, the fixing box 12 is fixed by the wedge block 13. Under the push of the inclined surface of the wedge block 13, the fixing box 12 drives the push block 15 to press against the mounting block 8, which can stably fix the mounting block 8 inside the mounting frame 5.
