Description

Technical Field

[0001] This utility model relates to an air-expelling device, and more particularly to a self-cleaning air-expelling device for a fresh air system. Background Technology

[0002] The fifth-generation mobile communication technology (referred to as 5G or 5G technology) is the latest generation of cellular mobile communication technology. With the accelerated construction of 5G base stations in various cities, the demand for integrated outdoor cabinets for 5G base stations is increasing.

[0003] 5G base stations consume 6-7 times more power than 4G base stations. Due to the significantly increased power consumption of 5G cabinets, the IT equipment inside generates a large amount of heat, requiring air conditioning with higher cooling capacity. In 5G cabinet applications, lithium batteries have higher temperature tolerance and smaller size under the same conditions. Currently, cabinets generally use lithium batteries, which have a wider operating temperature range, capable of operating at 40-60℃ for short periods. With advancements in battery technology, batteries can withstand even higher temperatures. The most effective solution to the surge in power consumption of 5G cabinets is to introduce large amounts of outdoor air into the cabinet and then exhaust it to remove heat, replacing or replacing air conditioning. With the development of 5G, conventional methods involve opening diagonally at the base station to increase internal airflow and installing filters at the air inlets. However, this approach suffers from problems such as easy clogging of the air inlets, poor maintainability, and high maintenance costs. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] like Figures 1-3 As shown, a self-cleaning air intake device for a fresh air system includes an air inlet hood body 1, which consists of a connecting part 2 and a mounting part 3. The mounting part 3 is fixedly connected to the connecting part 2 by screws. A filter screen 12 is provided at the bottom of the mounting part 3, and the top of the mounting part 3 is fixedly connected to a drive motor 5 via an inner bracket 4. The drive motor 5 is connected to an external controller, which can control the speed of the drive motor 5. The drive motor 5 is a forward and reverse reversible motor. A lead wire groove is provided on the side of the inner bracket 4 for installing the wires connecting the drive motor 5. Blades 6 and 7 are fixedly arranged sequentially from top to bottom at the output end of the drive motor 5. The ratchet 7, the output end of the drive motor 5 passes through the center of the filter screen 12, and the blade 6 and the ratchet 7 are located on both sides of the filter element 12. The ratchet 7 can only rotate in one direction and be subjected to force, while rotating in the other direction is not subjected to force. It is similar to the freewheel structure of the rear wheel of a bicycle, which is existing technology and will not be elaborated on here. A cleaning component 15 is fixedly installed on one side of the ratchet 7, and an annular support plate is fixedly installed at the bottom of the mounting part. The top edge of the annular support plate contacts the bottom edge of the toothed ring 8, and multiple rollers are embedded in the top edge of the annular support plate, which can support the side of the toothed ring 8 and enhance the firmness of the toothed ring 8 installation.

[0020] like Figure 4 The cleaning component 15 includes a circular mounting plate 14 and a toothed ring 8. The center of the circular mounting plate 14 is movably connected to the side of the ratchet 7 via a connecting rod 13. The connecting rod 13 can rotate around the center of the circular mounting plate 14. The side of the circular mounting plate 14 is fixedly connected to the inner wall of the toothed ring 8 via multiple mounting brackets 10. Preferably, there are three mounting brackets 10, but there can be more than three. Each mounting bracket 10 has a brush 11 on the side away from the connecting rod 13. The inner wall of the mounting part 3 is also provided with an inner toothed ring 9, which meshes with the toothed ring 8, allowing the cleaning component to rotate on its own.

[0021] In practical use, the device is installed on one side of the base station, and an exhaust vent is installed on the other side of the base station. The drive motor 5 is connected to an external controller. Fresh air enters the base station from one side of the air inlet hood 1 and exits from the exhaust vent, carrying away the heat generated inside the base station and cooling it down. Simultaneously, the drive motor 5 can be turned on, causing the blades to rotate. At this time, the ratchet 7 is not under force, and the cleaning component 15 does not move. This mode can further increase the airflow and velocity entering the base station, improving the cooling efficiency. The device can also be set to reverse the drive motor 5 after a certain period of time. 5. When the blades are flipped, the blades 6 act as a back-blowing mechanism, blowing the blockages attached to the filter screen 12 out of the air inlet shroud body 1. At the same time, the ratchet 7 is driven by force to rotate the cleaning component 15 around the output end of the drive motor. When the cleaning component 15 rotates, the brush 11 contacts the filter screen 12 to clean it. During this process, the toothed ring 8 structure on the cleaning component 15 is engaged with the internal toothed ring 9 inside the mounting part 3, causing the cleaning component 15 to rotate inside the internal toothed ring 9. This avoids the phenomenon that the brush 11 cleans the filter screen surface in one direction, resulting in poor cleaning effect. It also improves the self-cleaning effect and cleaning efficiency of the device.
