Description

Technical Field

[0001] This utility model relates to the field of fresh air system technology, specifically to an outdoor air vent structure for an underground parking garage. Background Technology

[0002] Outdoor air vents in underground parking garages are key components of a building's ventilation system. They primarily facilitate air exchange between the inside and outside of the garage, ensuring adequate air quality and expelling harmful gases. Their design typically employs a rainproof louver structure; the angled blades effectively block rainwater and debris while allowing free airflow. The vents are often made of corrosion-resistant aluminum alloy or stainless steel, balancing strength and durability. Some high-end projects also incorporate sound-absorbing layers inside the vents to reduce fan noise. Installation locations are usually chosen on the garage side walls or in concealed areas, satisfying ventilation efficiency without affecting the building's appearance. They are a crucial element in ensuring environmental protection in underground spaces. Traditional outdoor air vents in underground parking garages are typically normally open structures made of concrete. In the event of a fire, air entering through these vents can intensify the flames, posing a significant safety hazard. Utility Model Content

[0003] The purpose of this utility model is to provide an outdoor ventilation structure for underground parking garages, in order to solve the problem mentioned in the background art that the traditional outdoor ventilation vents for underground parking garages are usually open structures made of concrete.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an outdoor ventilation structure for an underground parking garage, comprising a main frame, louvers mounted on the side walls of the main frame, and a set of sealing plates arranged sequentially from top to bottom on each side wall of the main frame and inside the louvers. The upper end of the sealing plate is rotatably connected to the main frame via a pivot. A synchronizing rod is provided at the middle position of the inner side of each set of sealing plates, and the outer side of the synchronizing rod is rotatably connected to the middle position of the lower edge of the sealing plate via a pivot. A connecting seat is provided at the middle position inside the main frame, and a pull rod is rotatably connected between the connecting seat and the four synchronizing rods via a pivot. A top plate is provided at the upper end of the main frame, and a magnetic disconnector is provided at the middle position of the lower surface of the top plate. The middle position of the upper surface of the connecting seat is connected to the lower end of the magnetic disconnector via a cable.

[0005] Preferably, a concrete base is provided below the main frame, the main frame rests on the concrete base, and a ventilation shaft is provided through the middle of the concrete base, the ventilation shaft being connected to the inner cavity of the main frame.

[0006] Preferably, the side wall of the main frame and the lower end of the louvers are provided with a crossbeam, the louvers are arranged on the crossbeam, and the side wall of the main frame and the lower end of the crossbeam are provided with a fire-resistant plate.

[0007] Preferably, the upper end of the main frame is provided with a top beam, the top plate is disposed on the top beam, and the upper end of the louver rests on the top beam.

[0008] Preferably, the four tie rods are rotatably connected to the connecting seat to form a cross-shaped structure.

[0009] Compared with the prior art, the beneficial effects of this utility model are: replacing the traditional normally open outdoor air vents in underground garages made of concrete, a metal frame structure air vent is set on the concrete foundation, and an openable closed plate structure is set inside the air vent.

[0016] 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.

[0017] Please see Figure 1-5 This utility model provides an outdoor ventilation structure for an underground garage, including a main frame 1. Louvers 2 are mounted on the side walls of the main frame 1. A set of sealing plates 3 are sequentially arranged from top to bottom on each side wall of the main frame 1 and inside the louvers 2. The upper end of each sealing plate 3 is rotatably connected to the main frame 1 via a pivot. A synchronizing rod 4 is located at the middle of the inner side of each set of sealing plates 3. The outer side of each synchronizing rod 4 is rotatably connected to the middle of the lower edge of the sealing plate 3 via a pivot. A connecting seat 5 is located at the middle of the inner side of the main frame 1. A pull rod 6 is rotatably connected between the connecting seat 5 and the four synchronizing rods 4 via a pivot. A top plate 7 is located at the upper end of the main frame 1. A magnetic disconnector 8 is located at the middle of the lower surface of the top plate 7. The middle of the upper surface of the connecting seat 5 is connected to the lower end of the magnetic disconnector 8 via a cable 9.

[0018] In normal operation, the magnetic disconnector 8 is energized and pulls the connecting seat 5 via the cable 9, keeping the connecting seat 5 in a high position. The connecting seat 5 pulls the synchronizing rod 4 via the pull rod 6, which synchronously operates a set of enclosed plates 3. The synchronizing rod 4 is rotatably connected to the lower end of the enclosed plate 3, and the upper end of the enclosed plate 3 is rotatably connected to the main frame 1, thereby opening the lower end of the enclosed plate 3. External air is then introduced into the interior of the main frame 1 through the gap between the louvers 2 and the enclosed plate 3 by the action of the fan, ensuring ventilation for the underground garage. In the event of a fire, the magnetic disconnector 8 receives a shutdown signal and stops working. The cable 9 and the connecting seat 5 disengage from the magnetic disconnector 8, and the connecting seat 5 moves downward under its own weight. Through the pull rod 6 and the synchronizing rod 4, the enclosed plate 3 is pushed and closed by its own action, thereby closing the entire air vent, reducing the air entering the underground garage, and thus delaying the fire.

The ventilation shaft 11 is connected to the inner cavity of the main frame 1. By setting the concrete base 10, the overall structural strength is ensured while the waterproof performance is improved. The ventilation shaft 11 is set inside the concrete base 10 so that external air can be introduced into the interior of the underground garage through the ventilation shaft 11.

[0020] A crossbeam 12 is provided on the side wall of the main frame 1 and at the lower end of the louver 2. The louver 2 is mounted on the crossbeam 12. A fire-resistant plate 13 is provided on the side wall of the main frame 1 and at the lower end of the crossbeam 12. The crossbeam 12 is provided inside the main frame 1 to fix the louver 2 and the fire-resistant plate 13 to ensure the connection strength.

[0021] The main frame 1 is provided with a top beam 14 at its upper end, the top plate 7 is set on the top beam, and the upper end of the louver 2 abuts against the top beam 14. The top beam 14 is provided at the upper end of the main frame 1, and the overall strength of the main frame 1 is improved while the top plate 7 is set at the upper end of the main frame 1.

[0022] The four pull rods 6 are rotatably connected to the connecting seat 5 to form a cross-shaped structure. The up and down movement of the connecting seat 5 can simultaneously drive the four pull rods 6 to pull the four synchronous rods 4.
