Description

Technical Field

[0001] This utility model relates to the field of underground garage ventilation technology, and in particular to a ventilation device for underground garages. Background Technology

[0002] Underground parking garages need to meet high requirements for fire-fighting air supply and daily air supply to ensure normal air circulation and to effectively provide fire-fighting air supply in the event of fire or other safety hazards, thereby ensuring the safe evacuation of personnel.

[0003] Publication No. CN214949574U discloses a make-up air device and a building system for underground parking garages. The make-up air device for underground parking garages includes: a make-up air fan, which connects the underground parking garage and the outdoor space through a make-up air duct to supply air into the underground parking garage; a hoisted make-up air fan room for housing the make-up air fan; and a hoisting mechanism on which the hoisted make-up air fan room is installed to suspend and install the hoisted make-up air fan room on the roof of the underground parking garage. By setting up a hoisting mechanism and fixing the hoisted make-up air fan room on the roof of the underground parking garage, the problem of low utilization rate of underground parking garages caused by the hoisted make-up air fan room occupying the ground space of the underground parking garage in the prior art can be effectively solved.

[0004] Existing air supply equipment used in underground parking garages can only blow air in one direction, cannot adjust the blowing angle, and cannot perform ventilation and sterilization, resulting in poor performance. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing air supply equipment for underground parking garages, which can only blow air in one direction, cannot adjust the blowing angle, cannot perform ventilation and sterilization, and have poor performance. Therefore, this invention proposes an air supply equipment for underground parking garages.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A makeup air device for an underground parking garage includes:

[0008] At least two air ducts, the air ducts are rectangular in structure, and bolt connecting pieces are provided at both ends of the air ducts. Two air ducts that are close to each other are fixedly connected by bolt connecting pieces and bolts. The air duct at the tail end is equipped with a sealing plate and the air duct at the head end is equipped with a connecting plate.

[0009] Multiple air blowing mechanisms are installed on the air duct, with two air blowing mechanisms installed on each air duct.

[0010] Multiple suspension structures are connected to the air duct;

[0011] The dustproof and sterilization mechanism is installed on the connecting plate.

[0012] Preferably, the suspension mechanism includes a rectangular frame, which is fitted over the outside of the air duct and fixed by bolts. Two hydraulic shock absorbers are fixedly installed on the top of the rectangular frame. The top of each hydraulic shock absorber is fitted with a mounting plate, which has multiple mounting holes for installation on the garage wall. The hydraulic shock absorbers can buffer and dampen the air duct.

[0013] Preferably, the air blowing mechanism includes two bends, both of which are rotatably mounted on the outside of the duct via bearings. The two bends are symmetrically arranged, and a V-shaped rod is fixedly installed on the inner side of each bend. A common round rod is fixedly installed between the two V-shaped rods. Multiple air vanes are fixedly installed on the outer side of the round rod, and the multiple air vanes are located inside the duct. The included angle of the bends is 120°. The airflow blows the multiple air vanes, causing the round rod and the two V-shaped rods to rotate. The two V-shaped rods drive the corresponding two bends to rotate, which can adjust the air guiding angle and position of the two bends.

[0014] Preferably, the connecting plate has a through hole, and a fan is provided inside the through hole.

[0015] Preferably, the dustproof sterilization mechanism includes a cylinder, an ultraviolet sterilization lamp is provided on the inner side of the cylinder, the ultraviolet sterilization lamp has a ring structure and is installed on the inner wall of the cylinder, and a controller is provided on the ultraviolet sterilization lamp.

[0016] Preferably, a dustproof plate is installed at the outer end of the cylinder, and the dustproof plate has multiple dustproof holes.

[0017] The beneficial effects of the air supply device for underground parking garages described in this utility model are as follows:

[0018] This solution suspends the ductwork using mounting plates and hydraulic shock absorbers. The hydraulic shock absorbers can buffer and dampen the ductwork.

[0019] The fan in this system draws outside air into the cylinder after it is filtered through a dustproof plate. The ultraviolet sterilization lamp can sterilize the air during ventilation. The sterilized air flows into the interior of the air duct and then is discharged through multiple bends, achieving the purpose of ventilation and air replenishment.

[0020] In this design, the airflow blows multiple air vanes, causing the round rod and two V-shaped rods to rotate. The two V-shaped rods then drive the corresponding two bends to rotate, allowing adjustment of the airflow angle and position of the two bends.

[0021] This utility model has a simple structure. The number of air ducts can be increased and the length can be adjusted according to usage requirements. The ultraviolet sterilization lamp can sterilize during ventilation, and the air guiding angle and position of the two bends can be automatically adjusted during air replenishment.

Two hydraulic shock absorbers 5 are fixedly installed on the top of the rectangular frame 4. An installation plate 6 is installed on the top of the hydraulic shock absorber 5. The installation plate 6 has multiple installation holes for installation on the garage wall top. The hydraulic shock absorbers 5 can buffer and dampen the air duct 1.

[0034] Reference Figure 3 , Figure 4 In this embodiment, the air blowing mechanism 9 includes two bent pipes 91. Both bent pipes 91 are rotatably mounted on the outside of the air duct 1 via bearings. The two bent pipes 91 are symmetrically arranged. V-shaped rods 92 are fixedly installed on the inner side of each of the two bent pipes 91. A common round rod 93 is fixedly installed between the two V-shaped rods 92. Multiple air vanes 94 are fixedly installed on the outer side of the round rod 93. The multiple air vanes 94 are all located inside the air duct 1. The included angle of the bent pipes 91 is 120°. The airflow blows the multiple air vanes 94, causing the round rod 93 and the two V-shaped rods 92 to rotate. The two V-shaped rods 92 cause the corresponding two bent pipes 91 to rotate, which can adjust the air guiding angle and position of the two bent pipes 91.

[0035] Reference Figure 5 , Figure 6 In this embodiment, a through hole 15 is provided on the connecting plate 7, and a fan 13 is provided inside the through hole 15.

When the fan 13 is working, it draws outside air into the cylinder 8 after filtering it through the dustproof plate 11. The ultraviolet sterilization lamp 16 can sterilize the air during ventilation. The sterilized air flows into the interior of the air duct 1 and then is discharged through multiple bends 91 to achieve the purpose of ventilation and air replenishment. At the same time, the airflow blows multiple air vanes 94, which drive the round rod 93 and two V-shaped rods 92 to rotate. The two V-shaped rods 92 drive the corresponding two bends 91 to rotate, which can adjust the air guiding angle and position of the two bends 91. The hydraulic shock absorber 5 can buffer and dampen the air duct 1.
