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.

[0028] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods. Example

[0029] Please see Figure 1-4 The present invention provides the following technical solution:

[0030] A sensing-type ventilation device for an underground parking garage includes: an exhaust pipe 1; the bottom end of the exhaust pipe 1 is located inside the underground parking garage, and its top end is located at the outside ground; a connecting ring 2 is provided inside the exhaust pipe 1, and a mounting plate 4 is provided on the inner side of the connecting ring 2, the mounting plate 4 being fixed to the inner side of the connecting ring 2 by a supporting strip 3; a motor 5 is mounted on the top of the mounting plate 4, a drive rod 6 penetrating the mounting plate 4 is fixed to the output end of the motor 5, and an exhaust fan 7 is fixed to the bottom of the drive rod 6; a connecting mechanism is provided at the bottom of the connecting ring 2 for fixing the connecting ring 2; a connecting seat 16 is fixed to the outer wall of the exhaust pipe 1, and an exhaust fan 7 is mounted on the top of the connecting seat 16. A carbon dioxide concentration detector 17 is provided, which is connected to an external terminal for communication. The connection mechanism includes connecting strips 8 symmetrically fixed at the bottom of the connecting ring 2. The outer walls of the two connecting strips 8 are provided with first locking holes 9. The outer walls of the exhaust pipe 1 are provided with two second locking holes 10. The two sets of first locking holes 9 and second locking holes 10 are each fitted with locking posts 11. The outer walls of the two locking posts 11 are each fixed with arc rods 12. One end of the two arc rods 12 is fixed with a connecting plate 13. The opposite ends of the two connecting plates 13 are fixed with telescopic rods 14. The outer walls of the telescopic rods 14 are provided with springs 15. The two ends of the springs 15 are respectively fixed to the two connecting plates 13.

[0031] Specifically, this invention features a carbon dioxide concentration detector 17 installed on the outer wall of the exhaust duct 1. Since the carbon dioxide concentration detector 17 is connected to an external terminal, it sends an alarm to the external terminal when it detects excessively high carbon dioxide levels in the underground parking garage. This alerts staff to the high levels of carbon dioxide in the underground parking garage. Staff then start the motor 5, which drives the exhaust fan 7 via the drive rod 6. At this time, outside air enters the underground parking garage through the exhaust duct 1, improving the air quality. Compared to existing designs, this invention has a sensing function, enabling it to alert staff to turn on the exhaust fan 7 based on the actual air quality in the underground parking garage, thus meeting existing needs.

[0032] At the same time, by driving the two locking pins 11, the two arc rods 12, and the two connecting plates 13 to move away from each other, the spring 15 and the telescopic rod 14 will perform corresponding stretching movements. After the two locking pins 11 are disengaged from the first locking hole 9 and the second locking hole 10, the two connecting strips 8, the connecting ring 2, the receiving strip 3, the mounting plate 4, the motor 5, the drive rod 6, and the exhaust fan 7 can be disassembled to facilitate the maintenance of the motor 5 and the exhaust fan 7.

[0033] The carbon dioxide concentration detector 17 in this embodiment is model THCMX4xG. Example

[0034] Please see Figure 1 , 2 4, 5, This utility model provides a technical solution: a sensing ventilation device for underground parking garages, wherein a first connecting column 18 is fixed to the top of the connecting ring 2, a baffle plate 19 is fixed to the top of the first connecting column 18, a rubber ring 20 that fits against the inner wall of the ventilation pipe 1 is installed on the outer wall of the baffle plate 19, a second connecting column 21 is fixed to the top of the ventilation pipe 1, a baffle plate 22 is fixed to the top of the second connecting column 21, a baffle ring 23 is fixed to the bottom of the baffle plate 22, and there is a distance between the baffle ring 23 and the ventilation pipe 1.

[0035] Specifically, the connecting ring 2 is connected to the baffle plate 19 via the first connecting post 18. Since the baffle plate 19 is located above the motor 5, it can prevent the motor 5 from being damaged by hard objects, thereby improving the working efficiency and service life of the motor 5. Furthermore, a rubber ring 20 that fits against the inner wall of the exhaust pipe 1 is installed on the outer wall of the baffle plate 19. The rubber ring 20 can improve the sealing of the connection between the baffle plate 19 and the exhaust pipe 1, thereby enhancing the protective effect of the baffle plate 19 on the motor 5.

[0036] Referring to Embodiment 1, when disassembling the motor 5 and the exhaust fan 7, the baffle plate 19 can be disassembled at the same time to facilitate cleaning of the baffle plate 19 and avoid the baffle plate 19 affecting the exhaust efficiency of the exhaust pipe 1.

[0037] like Figure 5 As shown, a baffle 22 is fixed to the top of the exhaust duct 1 by several evenly arranged second connecting columns 21. A retaining ring 23 is fixed at the bottom of the outer periphery of the baffle 22. With the cooperation of the baffle 22 and the retaining ring 23, rainwater can be prevented from entering the exhaust duct 1, thus preventing the motor 5 from being damaged by moisture. Furthermore, the carbon dioxide gas discharged from the underground parking lot by the motor 5 can be discharged through the gap between adjacent second connecting columns 21.

[0038] Working principle:

[0039] First, the exhaust duct 1 is buried in the designated area, with its bottom end inside the underground parking garage and its top end above the outside ground. A carbon dioxide concentration detector 17 is installed on the outer wall of the exhaust duct 1. Since the carbon dioxide concentration detector 17 is connected to an external terminal, when the carbon dioxide concentration detector 17 detects that the carbon dioxide content in the underground parking garage is too high, it will send an alarm to the external terminal to remind the staff that the carbon dioxide concentration in the underground parking garage is too high. Then, the staff will start the motor 5, which drives the exhaust fan 7 through the drive rod 6. At this time, outside air will enter the underground parking garage through the exhaust duct 1, thereby improving the air environment of the underground parking garage.

[0040] When inspecting and maintaining the sensor-type exhaust device of this utility model, the operator drives the two locking posts 11, the two arc rods 12, and the two connecting plates 13 to move away from each other. At this time, the spring 15 and the telescopic rod 14 will perform corresponding stretching movements. After the two locking posts 11 are disengaged from the first locking hole 9 and the second locking hole 10, the two connecting strips 8, the connecting ring 2, the receiving strip 3, the mounting plate 4, the motor 5, the drive rod 6, and the exhaust fan 7 can be disassembled to facilitate the maintenance of the motor 5 and the exhaust fan 7. The connecting ring 2 is connected to the blocking plate 19 through the first connecting post 18. The baffle plate 19 is located above the motor 5. Under the action of the baffle plate 19, the motor 5 can be prevented from being damaged by hard objects, thereby improving the working efficiency and service life of the motor 5. Furthermore, a rubber ring 20 is installed on the outer wall of the baffle plate 19, which fits against the inner wall of the exhaust pipe 1. The rubber ring 20 can improve the sealing at the connection between the baffle plate 19 and the exhaust pipe 1, thereby improving the protective effect of the baffle plate 19 on the motor 5. When disassembling the motor 5 and the exhaust fan 7, the baffle plate 19 can be disassembled at the same time, so as to facilitate the cleaning of the baffle plate 19 and prevent the baffle plate 19 from affecting the exhaust efficiency of the exhaust pipe 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
