Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of civil air defence basement ventilation, specifically to a civil air defence basement ventilation structure with adjustable air inlet angle. BACKGROUND

[0002] Civil air defence works are underground protective buildings built to protect people's lives and property safety and defend against enemy air raids. Its ventilation system is a key part to ensure internal air quality and personnel safety. However, civil air defence ventilation shaft is not only a part of the basement ventilation structure, but also has more extensive functions and importance. Civil air defence ventilation shaft plays multiple roles in civil air defence works, including ventilation function, wartime protection, emergency escape, fire fighting function, structural safety, and auxiliary function. Civil air defence ventilation shaft provides necessary ventilation for underground space and ensures air circulation.

[0003] For example, the basement ventilation structure disclosed in Chinese patent CN214370754U includes a basement, an air inlet pipe and an air outlet pipe arranged in the top wall of the basement. The air inlet pipe and the air outlet pipe are connected with the outside world. The air inlet pipe extends into the bottom of the basement and is fixed with a mounting frame. The mounting frame is internally provided with a rotatable louver fan. The side wall of the air inlet pipe is provided with a rotating connection mechanism for driving the louver fan. The inside of the air inlet pipe is provided with a rotating fan driven by the rotating connection mechanism. The rotating fan is located at the top of the louver fan. The application has the effect of improving the multidirectional flow of air. However, the air inlet angle of the traditional ventilation structure is fixed, and it is difficult to achieve the effect of full air inlet of the civil air defence basement. SUMMARY

[0011] Preferably, the adjustment component includes an adjustment tube disposed inside the top cover. A turntable is rotatably mounted on the top of the top cover, and the bottom end of the turntable is fixedly connected to the adjustment tube. Rotating the turntable on the top cover drives the internal adjustment tube to rotate, so that the ventilation groove on the adjustment tube corresponds to or offsets the ventilation groove on the top cover, thereby controlling the size of the ventilation groove.

[0012] Preferably, a filter screen is fixedly installed inside the top cover below the regulating pipe. The airflow enters through the ventilation slot of the top cover and is filtered by the filter screen.

[0013] Preferably, the rotating assembly includes an outer ring fixedly installed on the outer surface of the top end of the air inlet pipe. The top end of the air inlet pipe is rotatably connected to the bottom cover. A drive motor is fixedly installed inside the bottom cover. A gear is fixedly connected to the bottom end of the output shaft of the drive motor, and the gear meshes with the outer ring. During ventilation, the drive motor is started to drive the gear to rotate. The gear meshes with the outer ring at one end of the air inlet pipe, thereby driving the air inlet pipe to rotate and adjusting the direction and angle of the air intake.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a ventilation structure for civil defense basements with adjustable air intake angle, which has the following beneficial effects:

[0016] The air inlet pipe is movably connected to the bottom cover. During ventilation, the drive motor is started to drive the gear to rotate.
