Description

Technical Field

[0001] The present invention relates to the technical field of frequency conversion cabinets, and in particular to an integrated openable and closable dust removal mechanism for a frequency conversion cabinet. Background Art

[0002] A frequency converter cabinet is an electrical device used in the fields of power electronics and industrial automation. It is mainly used to control and adjust the speed and output power of AC motors. The core component is the frequency converter, which achieves precise control of the motor's operating status by changing the frequency and voltage of the output power supply.

[0003] A frequency converter cabinet typically consists of a cabinet body, electrical components, and a control system. The cabinet body provides mechanical support and protection; electrical components, such as circuit breakers, contactors, and relays, are responsible for switching and protecting the circuit; and the control system operates and monitors the frequency converter and other components.

[0004] In existing frequency converter cabinets, the cooling system is crucial for maintaining the stable operation of the electronic components within the cabinet. However, the cooling fan filters are very susceptible to dust absorption, resulting in reduced ventilation efficiency and weakened cooling effects. During the maintenance of traditional frequency converter cabinets, operators must first open the cabinet door and then manually clean the filters. This operation process is cumbersome and consumes a lot of time and manpower. Moreover, during the daily operation of the equipment, it is difficult to clean the filters in real time, and dust accumulation accumulates over time, affecting the cooling effect. In addition, manual cleaning methods may cause damage to components such as filters and fans due to improper operation, increasing the risk and repair costs of equipment maintenance. Therefore, it is necessary to design an integrated, openable and closable dust removal mechanism for frequency converter cabinets.

[0005] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Summary of the Invention

[0036] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0037] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] Reference Figures 1 to 8 As shown, an embodiment of the present invention provides an integrated openable and closable dust removal mechanism for a frequency conversion cabinet, comprising a frequency conversion cabinet body 11, an assembly component 2 and a dust removal component 3;

[0039] The frequency conversion cabinet 11 includes two groups of symmetrically distributed L-shaped guide slides 12, a groove plate 121 is fixedly installed on the horizontal end of the guide slide 12, and a guide rail 122 is fixedly installed on the vertical end of the guide slide 12. A symmetrically arranged frequency conversion cabinet door 13 and a frequency conversion cabinet door 2 17 are slidably installed between the two groups of guide slides 12. The top and bottom of the frequency conversion cabinet door 13 and the frequency conversion cabinet door 2 17 are fixedly installed at a right angle end position close to each other. A pulley 16 is installed on the fixing bar 15 through a bearing. The pulley 16 is adapted to be used with the groove plate 121 and can slide along the straight direction of the groove plate 121;

[0040] It should be noted that shielding plates 110 are fixedly mounted near both ends of the guide slide 12. When the inverter cabinet door 13 and the inverter cabinet door 2 17 slide toward the sides along the centerline of the inverter cabinet body 11, the fixing strip 15 contacts the shielding plates 110, thereby limiting the extent to which the inverter cabinet door 13 and the inverter cabinet door 2 17 can be expanded toward the sides.

[0041] In addition, multiple groups of sliding blocks 18 with equal spacing are fixedly installed on the surface of the frequency conversion cabinet door 13 and the frequency conversion cabinet door 2 17. The sliding blocks 18 are adapted to the guide rails 122 and are used to provide linear guidance when the frequency conversion cabinet door 13 and the frequency conversion cabinet door 2 17 slide to both sides along the center line of the frequency conversion cabinet body 11.

[0042] The frequency conversion cabinet door 13 and the frequency conversion cabinet door 2 17 are embedded with a perspective window 14, which is used for staff to view the internal situation of the frequency conversion cabinet 11;

[0043] like Figure 6-Figure 7 As shown, the assembly component 2 includes a connecting plate 21 mounted on the side of the center position of the guide slide 12. The connecting plate 21 plays a supporting and connecting role. A first rotating shaft 24 and a second rotating shaft 25 are vertically mounted on the connecting plate 21 through a bearing. A certain distance is maintained between the first rotating shaft 24 and the second rotating shaft 25.

[0044] To protect the gears and prevent dust, a second gear 27 is fixedly mounted on one end of the first rotating shaft 24 protruding from the connecting plate 21, and a first gear 26 is fixedly mounted on one end of the second rotating shaft 25 protruding from the connecting plate 21. A top cover 22 is connected and covered on the connecting plate 21. Part of the top cover 22 is fixedly connected to the frequency conversion cabinet 11 to support and fix the connecting plate 21. The top cover 22 has an inner groove structure to cover the first gear 26 and the second gear 27 to prevent dust.

[0045] At the same time, a sliding groove 211 is formed on the top cover 22, and a handle 29 is slidably mounted in the sliding groove 211. A sliding protrusion 210 is fixedly mounted on the bottom surface of the handle 29. The handle 29 is slidably connected to the sliding groove 211 via the sliding protrusion 210. At the same time, a tooth plate 28 is fixedly mounted on the side of the sliding protrusion 210 away from the handle 29. Both sides of the tooth plate 28 have symmetrically arranged tooth blocks. The tooth plate 28 is respectively meshed with the first gear 26 and the second gear 27 through the tooth blocks on both sides.

[0046] In the initial state, the handle 29 is connected to the upper surface of the top cover 22 by bolts, and at the same time, latch assemblies are fixedly installed at two right angle ends away from each other on the frequency conversion cabinet door 13 and the frequency conversion cabinet door 2 17 (refer to Figure 3 , not shown in the figure), the latch assembly adopts the spring pin structure of the prior art, consisting of a pin body, a spring and a locking button. The pin body is elastically installed in the mounting hole of the cabinet side panel by the spring, and the locking button extends to the outside of the cabinet for easy operation. When the frequency conversion cabinet door 13 and the frequency conversion cabinet door 2 17 slide along the guide slide 12 to a closed state in which they fit together, the pin body automatically pops out under the action of the spring and inserts into the pin hole preset at the vertical end of the guide slide 12, forming a mechanical lock. At this time, the wedge-shaped structure at the front end of the pin body closely matches the inner wall of the pin hole to prevent the cabinet door from sliding accidentally.

[0047] like Figure 7 As shown, one end of the first rotating shaft 24 extending into the connecting plate 21 is fixedly mounted with a fourth gear 213, and one end of the second rotating shaft 25 extending into the connecting plate 21 is fixedly mounted with a third gear 212. At the same time, a connecting plate 181 is fixedly mounted at the bottom of a group of sliding blocks 18 close to each other on the frequency conversion cabinet door 13 and the frequency conversion cabinet door 2 17. The connecting plate 181 of the frequency conversion cabinet door 13 has a second rack 216 fixedly mounted on one end, and the connecting plate 181 of the frequency conversion cabinet door 2 17 has a first rack 214 fixedly mounted on one end. At the same time, a guide groove (not shown in the figure) is provided on the guide slide portion 12 to provide sliding space for the second rack 216 and the first rack 214. The guide groove is adapted to the size of the rack to ensure that the rack can move with the cabinet door to slide smoothly in the groove;

[0048] In addition, a pin slot 19 is provided on the side of inverter door 13 that contacts the side of inverter door 2 17. A silicone sealant is located within pin slot 19, where it contacts inverter door 2 17. When inverter door 13 and inverter door 2 are closed, the sealant elastically deforms under compression, filling the small gap between the contact surfaces and forming a reliable seal. This effectively prevents dust, moisture, and other intrusions into the cabinet interior, ensuring that inverter door 13 and inverter door 2 17 are in a sealed, closed position by default.

[0049] When electronic components within the inverter cabinet 11 need to be repaired or replaced, the bolts connecting the handle 29 to the top cover 22 are first removed. The handle 29 is then held and slid until it rests against one end of the inner wall of the sliding groove 211. As the handle 29 moves, the sliding protrusion 210 drives the toothed plate 28 to move synchronously. As the toothed plate 28 moves, the toothed blocks on either side of the toothed plate 28 rotate, driving the first gear 26 and the second gear 27 meshing with it.

[0050] The first gear 26 and the second gear 27 rotate, thereby driving the first rotating shaft 24 and the second rotating shaft 25 fixed thereto to rotate. As the first rotating shaft 24 and the second rotating shaft 25 rotate, they also drive the fourth gear 213 and the third gear 212 thereon to rotate. As the fourth gear 213 and the third gear 212 rotate, they interact with the first rack 214 and the second rack 216 with which they are meshed, causing the first rack 214 and the second rack 216 to move away from each other. Because the first rack 214 and the second rack 216 are connected to the frequency conversion cabinet door 13 and the frequency conversion cabinet door 2 17, respectively, the electronic components inside the frequency conversion cabinet 11 that were originally covered are exposed, making it easier for staff to perform maintenance and replacement operations on the electronic components inside the frequency conversion cabinet 11. After maintenance and replacement are completed, the frequency conversion cabinet door 13 and the frequency conversion cabinet door 2 17 can be re-covered by reversing the operation, restoring the initial state.

[0051] When inspecting the electronic components within the inverter cabinet 11, first remove the bolts connecting the handle 29 to the top cover 22 to unlock it. Grip the handle 29 and slide it along the sliding groove 211. The handle 29, via the sliding protrusion 210, drives the toothed plate 28 to move synchronously. The toothed blocks on either side of the toothed plate 28 respectively drive the first gear 26 and the second gear 27 to rotate, thereby driving the first and second rotating shafts 24 and 25 to rotate synchronously. The fourth gear 213 and the third gear 212 at the ends of the first and second rotating shafts 24 and 25 rotate accordingly, meshing with the first and second racks 214 and 216, causing the racks to slide synchronously to the sides. Because the first and second racks 214 and 216 are fixed to the connecting plates 181 of the first and second inverter doors 13 and 17, respectively, the doors smoothly unfold to the sides, guided by the pulleys 16 and slot plates 121, and the sliding blocks 18 and guide rails 122, until the fixed bars 15 contact the baffles 110, completely exposing the interior of the cabinet. After maintenance is complete, the handles 29 are slid in the opposite direction, and the doors close along their original path. The spring forces the pins to automatically lock into place, while the silicone gaskets deform under pressure to achieve a seal.

[0052] Reference Figures 3 to 7 - Figure 8As shown, the dust removal assembly 3 is provided with two groups, and the two groups of dust removal assemblies 3 are respectively arranged on both sides of the frequency conversion cabinet 11. Each group of the dust removal assembly 3 includes an L-shaped support plate 111 fixedly mounted on the side of the frequency conversion cabinet 11. The support plate 111 is arranged parallel to the side of the frequency conversion cabinet 11. A plurality of groups of small fans 317 are embedded and installed on the support plate 111. The small fans 317 adopt an exhaust design, and the hot air inside the frequency conversion cabinet 11 is extracted through the axially rotating aluminum alloy fan blades, forming a directional airflow channel in the frequency conversion cabinet 11.

[0053] The blades of the small fan 317 are made of lightweight alloy material and are treated with a wear-resistant coating on the surface. While ensuring efficient operation, they also reduce wear and noise caused by long-term use. The small fan 317 can not only accelerate the flow of hot air inside the bus duct through forced convection, but also discharge the heat generated by the heating components in the frequency conversion cabinet 11, thereby achieving efficient heat dissipation and improving the stability and safety of the operation of the pad components in the frequency conversion cabinet 11;

[0054] At the same time, transparent holes (not shown in the figure) that are adapted to the diameter of the small fan 317 are opened on both sides of the frequency conversion cabinet 11. The transparent holes are distributed in a straight line with equal intervals, corresponding one-to-one to the installation position of the small fan 317, ensuring that the airflow generated by the fan can smoothly pass through the frequency conversion cabinet 11 to form an orderly air duct. At the same time, a guide inclined plate (not shown in the figure) is designed on the inner edge of the transparent hole. The angle of the inclined plate can guide the airflow generated by the small fan 317 to the heating area inside the frequency conversion cabinet 11, further improving the heat dissipation and dust removal effect.

[0055] like Figure 3 and Figure 8 As shown, the small fan 317 has a dust filter (not shown in the figure) on the side away from the frequency conversion cabinet 11. The dust filter is made of multi-layer composite fiber material, which can effectively intercept impurities such as dust and debris to prevent them from entering the interior of the fan and affecting the operating efficiency. A storage cover 33 is fixedly installed on the side of the support plate 111, and a spiral column 37 is installed on the bearing in the storage cover 33. A spiral groove 38 is opened on the spiral column 37 along its axial direction. At the same time, the spiral column 37 has a roller shaft, and the spiral column 37 is connected to the storage cover 33 bearing through the roller shaft. A fifth gear 36 is fixedly sleeved on the roller shaft of the spiral column 37. At the same time, a third rack 31 is fixedly installed on the bottom surface of the frequency conversion cabinet door 13 and the frequency conversion cabinet door 2 17. The third rack 31 is meshed with the fifth gear 36.

[0056] At the same time, a guide rod 39 is movably sleeved on the roller of the spiral column 37. The guide rod 39 is fixedly connected to one end surface of the storage cover 33. A driving rod 310 passes through the guide rod 39. One end of the driving rod 310 is a spherical structure. The spherical end of the driving rod 310 is embedded in the spiral groove 38. A guide groove (not shown in the figure) is opened on the guide rod 39 for the linear movement of the driving rod 310.

[0057] like Figure 3 As shown, a slide rail 312 is fixedly mounted on the right-angle end of the support plate 111, and a plurality of groups of sliders 314 are slidably mounted on the slide rail 312. The number of the sliders 314 is the same as the number of the small fans 317. At the same time, a vertically arranged cleaning brush 315 is threadedly connected to the slider 314. There is a specified spacing between the plurality of groups of cleaning brushes 315. In the initial state, the cleaning brush 315 is located on the side corresponding to the dust filter of the small fan 317, so as not to affect the normal use of the small fan 317.

[0058] At the same time, a fixed strip 311 is fixedly installed on the side of one end of the guide rod 39, and the fixed strip 311 is fixedly connected to multiple groups of sliders 314. At the same time, an isolation cover 313 is fixedly installed on the side of the support plate 111 to provide dust-proof shielding for the cleaning brush 315 in the default position. The isolation cover 313 is located on one side of the small fan 317, and the side of the isolation cover 313 is open.

[0059] In the present application, a dust shield can be fixedly mounted on the support plate 111 to shield the fifth gear 36 and prevent dust from falling onto the fifth gear 36 and affecting the transmission. At the same time, a long groove is provided on the dust shield for the third rack 31 to engage and move with the fifth gear 36.

[0060] When it is necessary to inspect the electronic components inside the frequency converter cabinet 11, first remove the bolts connecting the handle 29 to the top cover 22 to release the fixing restriction on the tooth plate 28. Gripping the handle 29, it slides along the sliding groove 211, driving the tooth plate 28 to move via the sliding protrusion 210. The tooth blocks on both sides of the tooth plate 28 drive the first gear 26 and the second gear 27 to rotate, thereby driving the first and second rotating shafts 24 and 25 to rotate. The fourth gear 213 and the third gear 212 at the ends of the first and second rotating shafts 24 and 25 rotate accordingly, meshing with the first and second racks 214 and 216 fixed to the connecting plates 181 of the frequency converter cabinet door 13 and the frequency converter cabinet door 2, 17, causing the two racks to slide to the sides.

[0061] The cabinet door is smoothly expanded to both sides under the guidance of the pulley 16 and the groove plate 121, the sliding block 18 and the guide rail 122 until the fixing bar 15 contacts the limit position with the baffle 110, exposing the interior of the cabinet; after the inspection is completed, the handle 29 is slid in the opposite direction, the cabinet door is closed along the original path, the spring pin is automatically inserted into the pin hole to lock it, and the silicone sealing gasket is compressed and deformed to achieve sealing.

[0062] The dust removal component 3 realizes its function through two groups of structures symmetrically distributed on both sides of the frequency conversion cabinet 11. The exhaust-type small fan 317 embedded on the L-shaped support plate 111 extracts the hot air inside the cabinet through the rotation of the aluminum alloy fan blades, and forms a directional airflow channel in cooperation with the transparent hole and the guide inclined plate to accelerate the discharge of heat. When the frequency conversion cabinet door 1 13 and the frequency conversion cabinet door 2 17 slide open and close, the third rack 31 on the bottom of the cabinet door engages with the fifth gear 36 on the spiral column 37, driving the spiral column 37 to rotate. The spiral groove 38 of the spiral column 37 cooperates with the spherical end of the drive rod 310 to convert the rotational motion into the linear motion of the drive rod 310 along the guide rod 39, and drives the slider 314 on the slide rail 312 to slide through the fixed strip 311, so that the cleaning brush 315 moves back and forth to clean the dust filter of the small fan 317 to prevent dust accumulation from affecting the efficiency of the fan. When the cleaning brush 315 is idle, it is shielded from dust by the isolation cover 313;

[0063] In summary, the various components of the inverter cabinet are linked through mechanical transmission. The rack-and-pinion drive system of assembly component 2 is tightly connected to the sliding mechanism of the cabinet door. The linear motion of handle 29 is transmitted via the gear shaft, controlling the synchronous opening and closing of the cabinet door. Dust removal component 3 is linked to the movement of the cabinet door. The sliding movement of the cabinet door triggers the automatic operation of the cleaning brush 315, thus automating the dust removal function. Furthermore, components within the cabinet structure, such as the guide 12, pulley 16, and slider 18, provide stable guidance for the various motion mechanisms, ensuring smooth operation and accurate positioning of the entire system.

[0064] The design of this frequency conversion cabinet has advantages. In terms of maintenance convenience, the double-sided cabinet doors can be quickly opened by operating the handle 29 with one hand, which greatly improves the maintenance efficiency.
