Description
Technical Field
[0001] This utility model relates to the field of fan cleaning technology, and in particular to a dust removal device for cleaning and removing dust from inverter cooling fans. Background Technology
[0002] In the fields of industrial automation and power control, frequency converters are widely used and are key equipment for achieving efficient speed regulation and energy-saving operation of motors. During their operation, the power devices inside the frequency converter generate a large amount of heat, which needs to be maintained at a suitable operating temperature by a cooling fan. However, industrial environments are usually complex and harsh, with high dust, high humidity, and a lot of lint. When the cooling fan is running, outside air is drawn in, and the dust particles it carries enter the inside of the frequency converter. Over time, these particles accumulate in large quantities on the fan blades, air ducts, and heat sink fins.
[0003] The device mainly consists of a dust removal brush assembly and a dust collection box. The dust removal brush assembly uses highly elastic and wear-resistant nylon bristles that fit closely against the cooling fan blades and radiator surface. During operation, the dust removal brush performs a reciprocating sweeping motion along the rotation direction of the cooling fan, peeling dust off the fan blades and radiator fins. The falling dust enters the bottom dust collection box under the action of gravity. After cleaning, the device achieves efficient cleaning and dust removal of the inverter cooling fan.
[0004] Current cleaning and dust removal devices for inverters lack adaptive clamping mechanisms to limit the inverter's movement when cleaning its cooling fans. They also lack convenient adjustment structures. Traditional devices often use fixed-specification clamping components, which are difficult to adapt to inverters of different sizes and shapes. Forced fixing can easily lead to inverter casing deformation or instability, affecting cleaning safety and stability. Furthermore, the lack of flexible adjustment structures makes it difficult to easily adjust the inverter's angle during cleaning, resulting in hard-to-reach areas of the cooling fan and creating cleaning blind spots. Therefore, this inverter cooling fan cleaning and dust removal device is proposed to solve these problems. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides a cleaning and dust removal device for inverter cooling fans, which aims to improve the problem of the lack of a clamping mechanism and adjustment structure in the prior art that can adaptively limit the inverter.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A frequency converter cooling fan cleaning and dust removal device includes a base, a collection box fixedly connected to the top of the base, a cleaning component disposed outside the collection box, a rotating disk rotatably connected inside the base, a motor fixedly connected inside the rotating disk, a rotating rod rotatably connected inside the rotating disk, a transmission rod rotatably connected outside the rotating rod, a moving block rotatably connected to the end of the transmission rod away from the rotating rod, a limiting block fixedly connected to the top of the moving block, a control rod fixedly connected to the top of the rotating disk, and a fixing component disposed inside the rotating disk.
[0008] As a further description of the above technical solution:
[0009] The rotating disk has a sliding groove inside, and the limiting block is slidably connected to the inside of the sliding groove.
[0010] As a further description of the above technical solution:
[0011] The fixing component includes a fixing column, the bottom end of which is fixedly connected to the inside of the rotating disk, and the top end of which is fixedly connected to a fixing disk.
[0012] As a further description of the above technical solution:
[0013] The bottom end of the moving block is slidably connected to the top end of the fixed disk, and the drive end of the motor is fixedly connected to the inside of the rotating rod;
[0014] As a further description of the above technical solution:
[0015] The rotating rod is externally rotatably connected to the inside of the fixed disk, and the plurality of limiting blocks are circumferentially distributed inside the rotating disk;
[0016] As a further description of the above technical solution:
[0017] The cleaning assembly includes a corrugated hose, the corrugated hose is fixedly connected to the outside of the collection box, a collection block is fixedly connected to the front end of the corrugated hose, a second fixing post is fixedly connected to the front end of the collection block, a sliding post is slidably connected to the outside of the second fixing post, a cleaning plate is fixedly connected to the front end of the sliding post, and a spring is fixedly connected to the front end of the second fixing post.
[0018] As a further description of the above technical solution:
[0019] The front end of the spring is fixedly connected to the inside of the sliding column, and the collecting block is V-shaped;
[0020] As a further description of the above technical solution:
[0021] The rotating rod is cross-shaped, and the top of the motor is fixedly connected to the bottom of the fixed plate.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, regarding the fixing and position adjustment of the frequency converter, after the operator places the frequency converter on the top of the rotating disk, the motor is started to drive the rotating rod to rotate, and the transmission rod pulls the moving block to slide on the fixed disk, so that multiple limiting blocks move along the sliding groove inside the rotating disk, clamping and limiting the frequency converter from different directions. This design can be adapted to frequency converters of various sizes and can be quickly fixed without complicated adjustments. At the same time, the operator can flexibly adjust the angle and orientation of the frequency converter by rotating the rotating disk with the control rod. During the cleaning process, all parts of the cooling fan can be easily exposed under the cleaning components, reducing cleaning dead corners, ensuring stable cleaning operation, and greatly improving cleaning efficiency.
[0024] 2. In this utility model, regarding cleaning and dust collection, after the inverter is fixed, the fan inside the collection box is started, creating suction within the corrugated hose and collection block. The operator manipulates the corrugated hose to make the cleaning plate contact the cooling fan. The sliding column slides outside the fixed column and compresses the spring. The elastic force generated by the spring pushes the sliding column, ensuring that the cleaning plate remains tightly attached to the fan surface. When the cleaning plate scrapes the fan, it peels off dust and impurities. Under the suction, this dust is sucked into the collection box through the corrugated hose. Throughout the process, the self-adaptive fit of the cleaning plate ensures the cleaning effect, and the automatic collection function prevents dust from spreading. This achieves efficient cleaning, ensures a clean working environment, and simplifies the cleaning process. Attached Figure Description

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.
[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a frequency converter cooling fan cleaning and dust removal device, including a base 1. The base 1 is integrally molded from high-strength engineering plastic and has an anti-slip rubber pad at the bottom to ensure the stability of the device when placed. A collection box 12 is fixedly connected to the top of the base 1 for collecting dust and impurities generated during the cleaning process. A cleaning component is provided on the outside of the collection box 12, which can efficiently remove dirt from the surface and crevices of the cooling fan. A rotating disk 2 is rotatably connected inside the base 1. The rotating disk 2 can rotate flexibly inside the base 1 to provide an adjustable placement platform for the frequency converter. A motor 5 is fixedly connected inside the rotating disk 2. The motor 5 serves as a power source to provide power for clamping and fixing the frequency converter. A rotating rod 6 is rotatably connected inside the rotating disk 2. The rotating rod 6 rotates under the drive of the motor 5, thereby driving the movement of subsequent components. A transmission rod 7 is rotatably connected to the outside of the rotating rod 6. The transmission rod 7 converts the rotation of the rotating rod 6 into linear motion. A moving block 8 is rotatably connected to the end of the transmission rod 7 away from the rotating rod 6. The moving block 8 slides on the fixed disk 4 under the drive of the transmission rod 7.
[0033] A limiting block 9 is fixedly connected to the top of the movable block 8. The limiting block 9 is used to clamp and limit the inverter. A control lever 3 is fixedly connected to the top of the rotating disk 2. The operator can easily rotate the rotating disk 2 by manipulating the control lever 3. A fixing component is set inside the rotating disk 2. A sliding groove 10 is opened inside the rotating disk 2. The sliding groove 10 provides a guide path for the sliding of the limiting block 9. The limiting block 9 is externally slidably connected to the inside of the sliding groove 10. The fixing component includes a fixing post 11. The bottom end of the fixing post 11 is fixedly connected to the inside of the rotating disk 2. A fixing disk 4 is fixedly connected to the top end of the fixing post 11. The fixed plate 4 provides a stable support plane for the sliding of the moving block 8. The bottom end of the moving block 8 is slidably connected to the top end of the fixed plate 4 to ensure the smoothness of the moving block 8 during sliding. The drive end of the motor 5 is fixedly connected to the inside of the rotating rod 6 to ensure effective power transmission. The outside of the rotating rod 6 is rotatably connected to the inside of the fixed plate 4 to ensure the stability of the rotation of the rotating rod 6. Multiple limiting blocks 9 are distributed in a circle inside the rotating plate 2 to evenly clamp the frequency converter from multiple directions. The rotating rod 6 is cross-shaped, which optimizes the force transmission path. The top end of the motor 5 is fixedly connected to the bottom end of the fixed plate 4 to make the installation of the motor 5 more stable.
[0034] Reference Figure 1 , Figure 2 and Figure 4 The cleaning assembly includes a corrugated hose 13, made of flexible and wear-resistant material, which can be freely bent and adjusted in angle. It is externally fixed to the outside of the collection box 12, enabling communication with the collection box 12. A collection block 14 is fixedly connected to the front end of the corrugated hose 13, guiding dust into the hose. A fixing post 15 is fixedly connected to the front end of the collection block 14. A sliding post 16 is slidably connected to the outside of the fixing post 15, providing support for the sliding of the sliding post 16. The sliding post 16 can slide flexibly on the fixing post 15. A cleaning plate is fixedly connected to the front end of the sliding post 16. 18. The cleaning plate 18 is used to scrape dust off the surface of the cooling fan. A spring 17 is fixedly connected to the front end of the fixed post 15. The spring 17 provides a force for the sliding post 16 to reset and press. The front end of the spring 17 is fixedly connected inside the sliding post 16. When the cleaning plate 18 contacts the fan, the spring 17 will be compressed as the sliding post 16 slides, so that the spring 17 continuously pushes the sliding post 16 to ensure that the cleaning plate 18 is continuously attached to the outside of the cooling fan, thereby scraping off dust and impurities. The collecting block 14 is V-shaped. This shape design helps to enhance suction and collect dust and impurities more effectively.
[0035] Working principle: When the operator needs to clean the cooling fan of the frequency converter, the outside of the frequency converter is placed on the top of the rotating disk 2. Then, the motor 5 is started, and the motor 5 drives the rotating rod 6 to rotate, which causes the transmission rod 7 to pull the moving block 8 to slide on the top of the fixed disk 4. This causes the outside of multiple limiting blocks 9 to slide inside the rotating disk 2, ultimately clamping and limiting the outside of the frequency converter. At the same time, the operator can control the control rod 3 to make the rotating disk 2 rotate inside the base 1, thereby changing the position of the frequency converter. By quickly limiting the position of frequency converters of different sizes, stability is ensured during subsequent cleaning, and the controllable angle change improves the cleaning efficiency.
[0036] Once the inverter's position is fixed, the fan inside the collection box 12 is activated, creating suction between the corrugated hose 13 and the collection block 14. The operator can then control the corrugated hose 13 to allow the cleaning plate 18 to scrape the inverter's cooling fan. When the cleaning plate 18 contacts the fan, the sliding column 16 slides outside the fixed column 15, and the spring 17 is compressed as the sliding column 16 slides, continuously pushing the sliding column 16 to ensure that the cleaning plate 18 remains in contact with the outside of the cooling fan. This scrapes off dust and impurities, which are then collected inside the collection box 12 via the corrugated hose 13, completing the cleaning and collection process.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
