[0031] Pipeline 1;

[0032] A first dust-proof pipe 3, the first dust-proof pipe 3 is fixedly connected to a side end of the pipeline 1;

[0033] A second dustproof tube 4, the second dustproof tube 4 is threadedly connected to the side end of the first dustproof tube 3 by means of bolts, and the side end of the second dustproof tube 4 is fixedly connected with a connecting tube 5;

[0034] The frame 6 is fixedly connected to the side end of the connecting pipe 5 , and the side end of the frame 6 is fixedly connected with the fan blade 7 .

[0035] In a specific embodiment of the utility model, the pipe 1 is the core part of the system, and the pipe 1 is used to guide the airflow to achieve ventilation. The material, size and shape of the pipe are designed according to the specific application scenario to ensure efficient airflow and sufficient strength. The first dustproof pipe 3 is connected to the side end of the pipe 1 to form a dustproof barrier to prevent external dust and debris from entering the inside of the pipe. This helps to keep the ventilation system clean and the indoor air quality. The second dustproof pipe 4 is threadedly connected to the side end of the first dustproof pipe 3 by bolts, further enhancing the dustproof effect and providing additional protection at the pipe outlet. The connecting pipe 5 connects the second dustproof pipe 4 and the frame 6 to ensure that the connection of the entire system is firm and facilitates airflow transmission. The frame 6 is fixedly connected to the side end of the connecting pipe 5 and is used to support the fan blade 7. The design of the frame 6 needs to consider strength, stability and durability to ensure long-term stable operation. The fan blades 7 are fixedly connected to the side end of the frame 6, and airflow is generated by rotation to achieve ventilation inside the building. The design and material of the fan blade 7 will affect the ventilation efficiency and noise level.

[0036] For details, please refer to Figure 1-Figure 3 The side end of the fan blade 7 is fixedly connected with a connecting rod 8, and the circumferential surface of the connecting rod 8 is fixedly connected with a dustproof baffle 9, which matches the connecting pipe 5.

[0037] In this embodiment: the side end of the fan blade 7 is fixedly connected with a connecting rod 8, and such a design can increase the structural stability of the fan blade and make it more secure when rotating. The function of the connecting rod 8 is to serve as a connecting component between the fan blade 7 and the frame 6 to ensure the stability and durability of the fan blade during ventilation. The circumferential surface of the connecting rod 8 is fixedly connected with a dustproof baffle 9, and this design further enhances the dustproof effect of the ventilation system. The function of the dustproof baffle 9 is to prevent dust and debris from entering the inside of the pipe through the gap between the fan blade 7 and the connecting pipe 5 during ventilation, thereby protecting the cleanliness of the ventilation system and the indoor air quality. The dustproof baffle 9 matches the connecting pipe 5, which means that the size and shape design of the dustproof baffle 9 should be consistent with the corresponding part of the connecting pipe 5 to ensure a good sealing effect. Such a design can ensure that the dustproof baffle 9 can effectively play its dustproof role in actual use. The design of this embodiment takes into account the practicality and dustproof effect of the ventilation system. By introducing the dustproof baffle 9 and the connecting rod 8, the overall performance of the ventilation system is further improved, making it more applicable in application scenarios such as the construction industry.

[0038] For details, please refer to Figure 2-Figure 4 A baffle plate 2 is fixedly connected to the side end of the pipeline 1 , and a rotating rod 10 is connected to the baffle plate 2 .

[0039] In this embodiment: the plate 2 can be used to control the direction and speed of the airflow to adapt to different ventilation needs. For example, in some cases, it may be necessary to limit the direction or intensity of the airflow to avoid interference or discomfort in the work area. A rotating rod 10 is connected to the baffle 2, which allows the baffle 2 to rotate along the rotating rod 10, thereby achieving precise control of the position of the baffle. The rotating rod 10 can be designed to allow the baffle 2 to switch between multiple fixed positions so that the ventilation effect can be adjusted as needed. In this embodiment, the design of the rotating rod 10 should ensure that the baffle 2 can be easily rotated, while also ensuring sufficient strength and stability to withstand the forces generated during the ventilation process. The connection method between the baffle 2 and the rotating rod 10 should be convenient for operation and maintenance to ensure long-term stable and reliable operation. In addition, the material selection of the baffle 2 and the rotating rod 10 should consider corrosion resistance, wear resistance and appropriate mechanical strength to adapt to different environmental conditions and long-term use. Through such a design, this embodiment provides a building ventilation and dust prevention duct system that is convenient for ventilation and airflow adjustment, which is flexible and practical and suitable for various buildings and industrial sites.

[0040] For details, please refer to Figure 1-Figure 4 A valve plate 11 is fixedly connected to the circumferential surface of the rotating rod 10 , and the valve plate 11 matches the pipeline 1 .

[0041] In this embodiment: In this embodiment, a valve plate 11 is fixedly connected to the circumferential surface of the rotating rod 10, and this design increases the control function of the ventilation system. The valve plate 11 can be one or more, and they are distributed along the circumferential surface of the rotating rod 10 to form an adjustable valve structure.

[0042] The valve plate 11 matches the pipe 1, which means that the size, shape and position of the valve plate are designed to match the corresponding part of the pipe to ensure a good sealing effect and effective airflow control. The valve plate 11 can be opened or closed by rotating the rotating rod 10, thereby adjusting the airflow size in the pipe 1 or completely cutting off the airflow. This design allows the user to adjust the performance of the ventilation system as needed. For example, when the ventilation volume needs to be increased, the valve plate 11 can be opened to allow more airflow to pass; and when ventilation is not required or the ventilation volume needs to be reduced, the valve plate 11 can be closed to save energy or prevent the loss of hot and cold air. In this embodiment, the connection method of the valve plate 11 and the rotating rod 10 should ensure that the movement of the valve plate is smooth and reliable, and at the same time, sufficient strength and durability should be ensured to withstand the forces that may be generated during long-term use and ventilation. Through such a design, this embodiment provides a building ventilation and dust prevention duct system with a convenient control function, which can flexibly adjust the ventilation effect according to actual needs and improve the practicality and efficiency of the system.

[0043] For details, please refer to Figure 1-Figure 4A sealing ring 12 is fixedly connected to the circumferential surface of the valve plate 11 , and the sealing ring 12 matches the pipeline 1 .

[0044] In this embodiment: the circumferential surface of the valve plate 11 is fixedly connected with a sealing ring 12, and this design further enhances the sealing performance of the ventilation system. The function of the sealing ring 12 is to ensure the sealing between the inside of the pipe 1 and the external environment when the valve plate 11 is opened and closed, and to prevent airflow leakage or external debris from entering the pipe. The sealing ring 12 matches the pipe 1, which means that the size, shape and material of the sealing ring should be adapted to the inner wall of the pipe to ensure that a good sealing effect can be provided when the valve plate 11 moves. Such a design can prevent energy loss caused by airflow leakage, and can also prevent external dust and other pollutants from entering the pipe, maintaining the cleanliness of the ventilation system and the indoor air quality. In this embodiment, the material selection of the sealing ring 12 should consider corrosion resistance, wear resistance and appropriate mechanical strength to adapt to different environmental conditions and long-term use. The installation position and method of the sealing ring 12 also need to consider the overall performance and maintenance convenience of the system. Through such a design, this embodiment provides a building ventilation and dustproof pipe system with excellent sealing performance, which can effectively adjust the airflow and maintain the stable operation of the system, and is suitable for buildings and industrial environments that require precise control of ventilation volume and prevention of pollution.

[0045] For details, please refer to Figure 2-Figure 4 A handle 13 is fixedly connected to the side end of the rotating rod 10 , and the handle 13 matches the baffle 2 .

[0046] In this embodiment: In this embodiment, the side end of the rotating rod 10 is fixedly connected with a handle 13, and such a design greatly improves the convenience of the ventilation system operation. The handle 13 is a component that a person can hold and operate, and it matches the baffle 2, which means that the size, shape and position design of the handle should match the corresponding part of the baffle 2, so that the user can control the position of the baffle 2 by operating the handle. By rotating the handle 13, the user can easily adjust the opening of the baffle 2, thereby controlling the flow and direction of the airflow in the ventilation system. This design allows the operation to be performed without directly touching the baffle 2, which not only ensures the safety of the operation, but also improves the efficiency of the operation. In this embodiment, the material selection of the handle 13 should take into account durability, grip comfort and appropriate mechanical strength to ensure long-term stable and reliable use. The connection method of the handle 13 should ensure firmness and reliability, and also be easy to maintain and replace. Through such a design, this embodiment provides a user-friendly building ventilation and dustproof duct system, which makes ventilation control easier and is suitable for buildings and industrial places that require convenient ventilation adjustment.

[0047] The working principle and use process of the utility model: First, install the pipe 1 to the appropriate position to ensure the verticality and horizontality of the pipe. Install the baffle 2 at the side end of the pipe, and use the connecting rod 8 and the dust baffle 9 to enhance the dustproof effect. Install the valve plate 11 on the circumferential surface of the rotating rod 10, and ensure that the sealing ring 12 matches the pipe 1 to provide a good sealing effect. Install the handle 13 at the side end of the rotating rod 10 to facilitate the operation of the valve. After the installation is completed, perform a system test to verify whether the airflow direction and flow rate of the ventilation system are as expected. Check all connection points to ensure that there are no leaks or looseness. Adjust the position of the baffle 2 by rotating the handle 13 as needed to control the flow rate and direction of the airflow. Check the system regularly and replace damaged sealing rings 12, valve plates 11 or other wear parts to ensure the long-term stable operation of the system. In daily use, adjust the position of the baffle 2 in time according to changes in the indoor and outdoor environment and ventilation needs.
