Description

Technical Field

[0001] This utility model relates to the field of ventilation equipment technology, and in particular to a ventilation and air exchange device for civil defense projects. Background Technology

[0002] Civil defense projects, as an important component of urban construction and protection systems, serve to protect the lives and property of the people, especially in emergencies such as war and natural disasters. Civil defense projects are divided into stand-alone underground protective structures and basements integrated with above-ground buildings for wartime air defense. Whether stand-alone or integrated with above-ground buildings, basements must ensure a safe and comfortable internal environment. Ventilation equipment plays a crucial role in this. Most civil defense projects are equipped with ventilation openings, with external fans and other equipment handling air intake and exhaust. However, due to prolonged disuse, dust accumulates at these ventilation openings. In the event of an emergency involving a large influx of people, this dust obstructs airflow during ventilation, hindering its effectiveness. Furthermore, the ventilation openings are typically located high up, making it difficult for evacuees to access and clean them during emergency evacuations. Utility Model Content

[0003] In view of this, this utility model proposes a ventilation and air exchange device for civil defense projects, which can automatically clean the protective cover and ensure that the air entering the basement can flow normally.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A ventilation and air exchange device for civil defense projects includes a basement main body, a ventilation duct, a protective cover, and a cleaning mechanism. The basement main body has ventilation openings on its side walls. One end of the ventilation duct is connected to the ventilation opening, and the other end extends to the ground. The protective cover is located inside the ventilation opening. The cleaning mechanism includes a linear guide rail, a moving plate, an electric turntable, a rotating plate, a return spring, a lifting plate, a cleaning brush, a rack, a rotary motor, and an incomplete gear. The linear guide rail is located on the top surface inside the basement main body, and its moving part is connected to the top surface of the moving plate. The electric turntable is located on the bottom surface of the moving plate, and its rotating surface is connected to the top surface of the rotating plate. The lifting plate is located below the rotating plate. The return spring connects the bottom surface of the rotating plate and the top surface of the lifting plate. The cleaning brush is located on the side wall of the lifting plate. The rack is located on the side wall of the lifting plate away from the cleaning brush. The rotary motor is located on the bottom surface of the rotating plate, and its output shaft is connected to the incomplete gear. The incomplete gear meshes with the rack. The protective cover is located on both sides of the moving path of the lifting plate.

[0006] Preferably, it also includes a fan, which is installed inside the ventilation duct.

[0007] Preferably, the cleaning mechanism further includes a mounting frame, which is disposed on the bottom surface of the rotating plate, and the rotary motor is disposed on the mounting frame.

[0008] Preferably, it also includes a filter screen disposed inside the end of the ventilation duct that extends to the ground.

[0009] Preferably, the cleaning mechanism further includes a sleeve and a limiting rod. The sleeve is disposed on the bottom surface of the rotating plate, the reset spring is located in the sleeve, the top end of the limiting rod extends into the sleeve and is connected to the reset spring, and its bottom end is connected to the top surface of the lifting plate.

[0010] Preferably, the lifting plate includes a support plate, a motor, and a tank. The bottom end of the limiting rod is connected to the top surface of the tank. One side of the tank is open.

[0019] To better understand the technical content of this utility model, a specific embodiment is provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0020] See Figures 1 to 3 This utility model provides a ventilation and air exchange device for civil defense projects, including a basement main body 1, a ventilation duct 2, a protective cover 3, and a cleaning mechanism. The basement main body 1 has ventilation openings 4 on its side walls. One end of the ventilation duct 2 is connected to the ventilation opening 4, and the other end extends to the ground. The protective cover 3 is located inside the ventilation opening 4. The cleaning mechanism includes a linear guide rail 5, a moving plate 6, an electric turntable 7, a rotating plate 8, a return spring 9, a lifting plate 10, a cleaning brush 11, a rack 12, a rotary motor 13, and an incomplete gear 14. The linear guide rail 5 is located on the inner top surface of the basement main body 1. The moving part is connected to the top surface of the moving plate 6. The electric turntable 7 is set on the bottom surface of the moving plate 6, and its rotating surface is connected to the top surface of the rotating plate 8. The lifting plate 10 is located below the rotating plate 8. The return spring 9 connects the bottom surface of the rotating plate 8 and the top surface of the lifting plate 10. The cleaning brush 11 is set on the side wall of the lifting plate 10. The rack 12 is set on the side wall of the lifting plate 10 away from the cleaning brush 11. The rotary motor 13 is set on the bottom surface of the rotating plate 8, and its output shaft is connected to the incomplete gear 14. The incomplete gear 14 meshes with the rack 12. The protective cover 3 is located on both sides of the moving path of the lifting plate 10.

[0021] The basement main body 1 is used to accommodate people for emergency refuge. Ventilation openings 4 are set on the upper sides of both sides of the basement main body 1. The outer side of the ventilation openings 4 is connected to the ventilation ducts 2. The other end of the ventilation ducts 2 extends upward to the ground. A ventilation and air exchange mechanism can be set on the ground. The clean air generated by the ventilation and air exchange mechanism can enter the interior of the basement main body 1 from the ventilation duct 2 on one side. The air inside the basement main body 1 can be transported to the outside from the ventilation duct 2 on the other side, thereby realizing ventilation and air exchange in the basement main body 1 and ensuring that people inside the basement main body 1 can breathe clean air. The protective cover 3 set at the ventilation openings 4 can prevent foreign objects from entering the interior of the basement main body 1 from the ventilation ducts 2, thereby improving the protective capability of the basement main body 1.

[0022] When the basement main body 1 is not used for a long time, a lot of dust will adhere to the inside of the protective cover 3. The dust will affect the air flow. In case of emergency, due to the height of the protective cover 3 and the lack of professional equipment, it is not possible to clean the protective cover 3 quickly by hand. This can easily lead to problems such as low air content in the basement main body 1. A linear guide rail 5 is set on the inner top surface of the basement main body 1. The linear guide rail 5 can drive the moving plate 6 to move horizontally, thereby moving the electric turntable 7, rotating plate 8 and lifting plate 10 below it to one side of the protective cover 3, so that the cleaning brush 11 contacts the protective cover 3. Then the rotary motor 13 is started, which drives the incomplete gear 14 to rotate. When the incomplete gear 14 meshes with the rack 12, it can drive the lifting plate 10 to descend. When the incomplete gear 14 disengages from the rack 12, the lifting plate 10 can rise under the action of the return spring 9, thereby realizing the vertical reciprocating motion of the lifting plate 10. During the reciprocating motion, the cleaning brush 11 can clean the dust on the protective cover 3 to avoid affecting the normal air flow.

[0023] An electric turntable 7 is installed at the bottom of the movable plate 6. The electric turntable 7 can drive the rotating plate 8 to rotate, so that the lifting plate 10 can rotate synchronously and adjust the orientation of the cleaning brush 11 so that the protective cover 3 in different positions can be cleaned, ensuring that the ventilation in the basement main body 1 can be carried out normally.

[0024] Preferably, it also includes a fan 15, which is disposed inside the ventilation duct 2.

[0025] The fan 15 is used to realize the flow of air, including bringing fresh outside air into the basement body 1 and transporting air out of the basement body 1.

[0026] Preferably, the cleaning mechanism further includes a mounting frame 16, which is disposed on the bottom surface of the rotating plate 8, and the rotary motor 13 is disposed on the mounting frame 16.

[0027] The mounting bracket 16 is used to mount the rotary motor 13 so that the height of the rotary motor 13 and the incomplete gear 14 can be adapted to the height of the lifting plate 10.

[0028] Preferably, it also includes a filter screen 17, which is disposed inside the end of the ventilation duct 2 that extends to the ground.

[0029] The filter 17 can filter impurities in the air flowing into the basement body 1, ensuring that the air entering the basement body 1 is clean.

[0030] Preferably, the cleaning mechanism further includes a sleeve 18 and a limiting rod 19. The sleeve 18 is disposed on the bottom surface of the rotating plate 8, the reset spring 9 is located in the sleeve 18, the top end of the limiting rod 19 extends into the sleeve 18 and is connected to the reset spring 9, and its bottom end is connected to the top surface of the lifting plate 10.

[0031] When the lifting plate 10 is running vertically back and forth, the limit rod 19 will move along the sleeve 18 to ensure that the movement of the entire lifting plate 10 is vertical up and down, so that the cleaning brush 11 can clean the protective cover 3 stably.

[0032] Preferably, the lifting plate 10 includes a support plate 20, a motor 21, and a trough 22. The bottom end of the limiting rod 19 is connected to the top surface of the trough 22. One side of the trough 22 is open. The support plate 20 is located on the open side of the trough 22. The motor 21 is disposed on the inner side wall of the trough 22, and its output shaft is connected to the side wall of the support plate 20. The cleaning brush 11 is disposed on the side wall of the support plate 20 away from the motor 21. The rack 12 is disposed on the side wall of the trough 22 away from the support plate 20.

[0033] The trough 22 can rotate with the rotating plate 8. At the same time, driven by the incomplete gear 14 and the rack 12, the trough 22 can be raised and lowered, thereby driving the support plate 20 and the cleaning brush 11 to be raised, lowered and rotated. In addition, during the cleaning process of the protective cover 3, the motor 21 can drive the support plate 20 to rotate, thereby cleaning the protective cover 3 by rotation and improving the cleaning effect.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
