Description

Technical Field

[0001] This invention relates to the field of electrical cabinet technology, and in particular to an electrical cabinet with good heat dissipation and dust prevention effects. Background Technology

[0002] With the advancement of industrial intelligence, electrical cabinets are developing towards larger size and higher integration. The dense electrical components inside the cabinet generate a lot of heat during operation. Electrical cabinets are usually equipped with ventilation openings and cooling fans to dissipate heat and ensure the stable operation of the entire electrical system. Dustproof structures such as grilles and filters are installed at the ventilation openings to filter and block dust, powder and other impurities from the outside world, so as to maintain a good operating environment inside the electrical cabinet.

[0003] During long-term operation of electrical cabinets, the dustproof structure will gradually become clogged due to the continuous accumulation of dust and debris, requiring manual cleaning. During cleaning, maintenance personnel need to manually remove the filter screen and then use tools such as brushes to clean it. The frequent manual disassembly makes cleaning the filter screen quite troublesome. If cleaning is not timely, dust and debris can easily block the ventilation openings, thus affecting the heat dissipation of the electrical cabinet. At the same time, the cooling fan is often fixed in a specific location, creating blind spots in the heat dissipation of the electrical cabinet and resulting in poor heat dissipation effect.

[0019] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] The following is for reference. Figures 1-7 An electrical cabinet 100 with good heat dissipation and dust prevention effect according to an embodiment of the present invention is described.

[0021] like Figures 1-7 As shown, the electrical cabinet 100 with good heat dissipation and dust prevention effect according to an embodiment of the present invention includes: cabinet body 10, filter assembly 20, drive assembly 30 and heat dissipation assembly 40.

[0022] Specifically, cabinet 10 in the first direction (e.g.) Figure 1 Ventilation openings are provided on both side walls (shown in the left and right directions); a filter assembly 20 is disposed at the ventilation openings, and the filter assembly 20 includes: a filter screen 22 and a vibration structure 23, the vibration structure 23 being configured to drive the filter screen 22 to reciprocate along a first direction to cause the filter screen 22 to vibrate; a drive assembly 30 includes: a rotating handle 31 and a transmission mechanism, the rotating handle 31 being connected to the vibration structure 23 via the transmission mechanism; a heat dissipation assembly 40 is disposed inside the cabinet 10, and the heat dissipation assembly 40 includes a heat dissipation fan 45, the heat dissipation fan 45 moving along the up and down direction (e.g., in the left and right directions) Figure 1 The vertical direction (as shown) is movable, and the vertical direction intersects with the first direction.

[0023] In this embodiment, the cabinet 10 has ventilation openings on both side walls in the first direction. The structure is simple, allowing outside air to enter the cabinet 10 through the ventilation openings to ventilate and dissipate heat from the electrical components. The filter assembly 20 is set at the ventilation opening, and the filter screen 22 can filter the outside air entering the cabinet 10, blocking dust and debris outside the cabinet 10, thereby achieving a dustproof effect.

[0024] In this embodiment, the filter assembly 20 is also provided with a vibration structure 23. The vibration structure 23 drives the filter screen plate 22 to move back and forth along the first direction to make the filter screen plate 22 vibrate. When the filter screen plate 22 vibrates, it can shake off the dust and debris accumulated on it, so that the filter screen plate 22 can achieve self-cleaning. The filter screen plate 22 does not need to be removed from the cabinet 10 for cleaning, thus avoiding frequent manual disassembly and cleaning operations, making the cleaning of the filter screen plate 22 more convenient and efficient. Moreover, since manual cleaning and disassembly operations are eliminated, the probability of dust and impurities entering the cabinet 10 during the cleaning process can be greatly reduced, and the probability of the filter screen plate 22 being blocked is greatly reduced. As a result, the electrical cabinet 100 can always maintain a good ventilation and heat dissipation state, thus making the heat dissipation effect of the electrical cabinet 100 better and more stable.

[0025] In this embodiment, a drive assembly 30 is provided, which includes a rotating handle 31 and a transmission mechanism. The rotating handle 31 is connected to the vibration structure 23 via the transmission mechanism. When the filter screen 22 of the electrical cabinet 100 is self-cleaning, the maintenance personnel can rotate the rotating handle 31 to drive the vibration structure 23 to vibrate and clean the filter screen 22. This is convenient to operate and can well meet the driving needs of the filter screen 22 during self-cleaning. The operation of the vibration structure 23 and the drive assembly 30 does not involve additional intelligent control systems, motors, or other equipment components, allowing the electrical cabinet 100 to achieve reliable dust prevention through efficient cleaning of the filter screen 22 at a low cost.

[0026] In this embodiment, a heat dissipation assembly 40 is provided inside the cabinet 10. The heat dissipation fan 45 in the heat dissipation assembly 40 is movable in the vertical direction, so that the heat dissipation working area of ​​the heat dissipation fan 45 can cover the vertical space inside the cabinet 10 as the heat dissipation fan 45 moves, thereby effectively reducing heat dissipation blind spots. This allows electrical components in all positions inside the electrical cabinet 100 to be cooled by the heat dissipation fan 45, and the electrical components in all positions are cooled by the same heat dissipation fan, making the heat dissipation effect of the electrical components in the electrical cabinet 100 more uniform and consistent, thereby making the heat dissipation effect of the electrical cabinet 100 better and the heat dissipation efficiency higher.

[0027] In this embodiment, by setting the cooling fan 45 to be movable in the vertical direction, the number of cooling fans 45 can be reduced while meeting the requirement of efficient heat dissipation for electrical components at various locations. This allows the heat dissipation assembly 40 to meet the need for efficient heat dissipation of the electrical cabinet 100 with fewer cooling fans 45, thereby further reducing the cost of the electrical cabinet 100.

[0028] According to an embodiment of the present invention, the electrical cabinet 100 with good heat dissipation and dust prevention effect is provided by setting a filter assembly 20 and a drive assembly 30. The rotating handle 31 of the drive assembly 30 is connected to the vibration structure 23 of the filter assembly 20 through a transmission mechanism, so that the filter screen 22 can shake off the accumulated dust and debris under the driving action of the rotating handle 31 to achieve self-cleaning without the need for manual removal and cleaning, thereby making the cleaning of the filter screen 22 more efficient and convenient, and effectively reducing the probability of vent blockage. At the same time, the heat dissipation fan 45 of the heat dissipation assembly 40 is movably arranged in the cabinet 10 in the vertical direction, so that the electrical components in all positions in the cabinet 10 can be cooled by the heat dissipation fan 45, effectively reducing heat dissipation blind spots, making the heat dissipation effect of the electrical cabinet 100 better, and making the cost of the electrical cabinet 100 lower.

[0029] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the number of filter components 20 can be two, with each filter component 20 corresponding to one of the two vents. Each filter component 20 may also include a fixed frame 21, which is fixedly connected to the side wall. A filter screen 22 is located on the side of the fixed frame 21 facing away from the cabinet 10 and is adapted to abut against the periphery of the fixed frame 21. The vibration structure 23 may include a cam 231 and a return spring 232. The cam 231 is located within the fixed frame 21 and is configured to intermittently squeeze the filter screen 22 by rotation, thereby pushing the filter screen 22 away from the fixed frame 21 along a first direction. The rotation axis of the cam 231 is along a second direction (e.g., ...). Figure 2 The second direction extends in the forward and backward direction shown, and intersects with the first direction. The return spring 232 can elastically deform along the first direction. The return spring 232 is located in the fixed frame 21. The two ends of the return spring 232 are connected to the fixed frame 21 and the filter screen plate 22 respectively. The return spring 232 is always in a stretched state to cooperate with the cam 231 to drive the filter screen plate 22 to move back and forth along the first direction.

[0030] In this embodiment, the number of filter components 20 is set to two, which are arranged one-to-one with the two vents. The arrangement is reasonable and meets the filtration and dust prevention needs of the electrical cabinet 100 at the two vents. The filter component 20 includes a fixed frame 21, which is fixedly connected to the side wall. For example, the fixed frame 21 can be directly welded to the cabinet body 10. The filter screen 22 is set on the side of the fixed frame 21 away from the cabinet body 10 and can abut against the periphery of the fixed frame 21. For example, the fixed frame 21 can extend into a ring along the circumference of the vent and be connected to the periphery of the vent. The filter screen 22 can abut against the circumferential end edge of the fixed frame 21 on the side away from the vent in the first direction. The filter screen 22 can cooperate with the fixed frame 21 to cover the vent, so that the outside air can be stably and reliably filtered by the filter screen 22 before entering the cabinet body 10.

[0031] The vibration structure 23 includes a cam 231 and a return spring 232. The cam 231 is disposed within the fixed frame 21, that is, the cam 231 is disposed on the side of the filter screen plate 22 facing the fixed frame 21. The cam 231 is configured to intermittently squeeze the filter screen plate 22 by rotation, pushing the filter screen plate 22 away from the fixed frame 21 along a first direction. In other words, the cam 231 intermittently applies a pushing force to the filter screen plate 22. The return spring 232 is disposed within the fixed frame 21 and its two ends are respectively connected to the fixed frame 21 and the filter screen plate 22. The return spring 232 is elastically deformable along the first direction and is always in a stretched state. Thus, the return spring 232 and the cam 231 are located on the same side of the filter screen plate 22 and always apply a pulling force to the filter screen plate 22, so that the filter screen plate 22 can... The filter screen 22 is kept in contact with the fixed frame 21 under the action of tension. The return spring 232 and the cam 231 work together to drive the filter screen 22 to move back and forth in the first direction. For example, when the cam 231 rotates, it intermittently applies a pushing force to the filter screen 22, so that the filter screen 22 overcomes the tension of the return spring 232 and moves away from the fixed frame 21 in the first direction. When the cam 231 continues to rotate, the pushing force applied by the cam 231 disappears. Under the action of the tension of the return spring 232, the filter screen 22 moves towards the fixed frame 21 in the first direction and abuts against the periphery of the fixed frame 21 under the limiting action of the fixed frame 21. Thus, the filter screen 22 continuously moves back and forth in the first direction during the continuous rotation of the cam 231, thereby realizing the vibration of the filter screen 22.

[0032] The dust and debris accumulated and intercepted on the filter screen 22 are shaken off and removed by the vibration of the filter screen. Since the filter screen 22 is outside the fixed frame 21, the falling dust and debris can fall more stably outside the cabinet 10, thereby reducing the amount of dust falling into the fixed frame 21 during vibration cleaning and making the cleaning effect of the filter screen 22 better.

[0033] In this embodiment, the reset spring 232 and the cam 231 are both arranged inside the fixed frame 21. The arrangement is reasonable and can reduce the external leakage of components, making the overall structure of the filter assembly 20 simpler. The fixed frame 21 can provide a good installation position and space for the filter screen 22, the reset spring 232 and the cam 231, so that the filter assembly 20 can be installed more stably and conveniently at the ventilation opening.

[0034] The purpose of the second direction intersecting with the first direction in this embodiment is to illustrate that the second direction and the first direction can be arranged perpendicularly, or they can be arranged to intersect but not perpendicularly, that is, they can intersect at an acute angle or an obtuse angle.

[0035] In one embodiment of the present invention, such as Figure 4 and Figure 5As shown, there can be multiple return springs 232, which are arranged at intervals along the circumference of the filter screen plate 22. The vibration structure 23 may also include: a fixed plate 235 and a guide rod 236. The fixed plate 235 is located on the side of the return spring 232 away from the filter screen plate 22 and is fixedly connected to the fixed frame 21. The return spring 232 is connected to the fixed plate 235. The guide rod 236 extends along the first direction. One end of the guide rod 236 is fixedly connected to the filter screen plate 22, and the other end of the guide rod 236 passes through the fixed plate 235. The other end of the guide rod 236 is provided with a limiting part 2361, which is limited and cooperates with the fixed plate 235 in the first direction. The return spring 232 is sleeved on the guide rod 236. There can be multiple guide rods 236, which are arranged one-to-one with the multiple return springs 232.

[0036] In this embodiment, multiple reset springs 232 are provided. For example, the number of reset springs 232 can be two, three, four, five, six, seven, etc. Multiple reset springs 232 are arranged at intervals along the circumference of the filter screen plate 22. For example, the number of reset springs 232 can be four. The four reset springs 232 can be arranged at the four corners of the filter screen plate 22 respectively, so that the filter screen plate 22 can move and reset more stably and reliably along the first direction to abut against the periphery of the fixed frame 21. Thus, during daily use, the filter screen plate 22 can stably and reliably close the opening of the fixed frame 21, so that the filter screen plate 22 can stably and reliably play a filtering role, so that the filter assembly 20 can have a more stable and reliable dustproof filtering effect at the ventilation opening.

[0037] In this embodiment, the vibration structure 23 is further provided with a fixing plate 235 and a guide rod 236. The fixing plate 235 is located on the side of the return spring 232 away from the filter screen plate 22 and is fixedly connected to the fixing frame 21. The return spring 232 is connected to the fixing plate 235. The structure is simple and easy to fix. The guide rod 236 extends along the first direction. One end of the guide rod 236 is connected to the filter screen plate 22 and the other end passes through the fixing plate 235 and is provided with a limiting part 2361. The return spring 232 is sleeved on the guide rod 236. Multiple guide rods 236 can cooperate to... The filter screen 22 provides stable support and guides the movement of the filter screen 22 in the first direction, allowing the filter screen 22 to move back and forth more stably in the first direction. The other end of the guide rod 236 is provided with a limiting part 2361, which cooperates with the fixing plate 235 in the first direction to limit the movement of the filter screen 22 to the fixing frame 21 through the guide rod and the fixing plate 235. This effectively limits the travel of the filter screen 22 away from the fixing frame 21, thereby improving the stability and reliability of the filter assembly 20 during operation.

[0038] In this embodiment, the return spring 232 is sleeved on the guide rod 236, which can effectively guide the elastic deformation direction of the return spring 232, allowing the return spring 232 to deform stably along the first direction, thereby making the movement of the filter screen plate 22 more stable and reliable. Multiple guide rods 236 are arranged in a one-to-one correspondence with multiple return springs 232, resulting in a simple structure and reasonable arrangement.

[0039] In one embodiment of the present invention, such as Figure 2 and Figure 3 As shown, the vibration structure 23 may further include: a first transmission shaft 233 and a first bevel gear 234. The first transmission shaft 233 extends along a second direction. One end of the first transmission shaft 233 is connected to the first bevel gear 234. The other end of the first transmission shaft 233 extends into the fixed frame 21 and is connected to the cam 231. The axis of the first transmission shaft 233 is collinear with the rotation axis of the cam 231. The transmission mechanism includes a second bevel gear 35, which meshes with the first bevel gear 234 for transmission.

[0040] In this embodiment, the vibration structure 23 also includes a first transmission shaft 233 and a first bevel gear 234. The first transmission shaft 233 extends along the second direction and its two ends are connected to the cam 231 and the first bevel gear 234 respectively. The axis of the first transmission shaft 233 is collinear with the rotation axis of the cam 231. The structure is simple and the arrangement is reasonable. The first bevel gear 234 meshes with the second bevel gear 35 of the transmission mechanism for transmission, and the transmission is stable and reliable. When the filter screen 22 needs to be cleaned, the maintenance personnel can turn the rotating handle 31 to drive the second bevel gear 35 of the transmission mechanism to rotate, thereby driving the first bevel gear 234 to rotate, so that the cam 231 rotates under the driving action of the first transmission shaft 233, and then the cam 231 cooperates with the return spring 232 to realize the vibration self-cleaning of the filter screen 22.

[0041] In this embodiment, one end of the first drive shaft 233 is connected to the first bevel gear 234 and the other end extends into the fixed frame 21 and is connected to the cam 231. This allows the transmission mechanism to be connected and assembled with the first bevel gear 234 on the outside of the fixed frame 21 via the first drive shaft 233, making it easier to assemble the filter assembly 20 and the drive assembly 30.

[0042] In some examples of the present invention, such as Figure 2 and Figure 3 As shown, the drive assembly 30 is located on one side of the cabinet 10 in the second direction, and the transmission mechanism may also include: a second drive shaft 34, a mounting base 36, a worm gear 33, and a worm 32.

[0043] Specifically, the second drive shaft 34 extends along the first direction, and both ends of the second drive shaft 34 are provided with second bevel gears 35; the mounting base 36 is fixedly connected to the cabinet 10, and the second drive shaft 34 is rotatably mounted on the mounting base 36; the worm gear 33 is provided on the second drive shaft 34, the worm 32 extends along the first direction and meshes with the worm gear 33 for transmission, and the rotating handle 31 is connected to the worm 32.

[0044] In this embodiment, the transmission mechanism is provided with a second transmission shaft 34, and a second bevel gear 35 is provided at both ends of the second transmission shaft 34. The structure is simple, so that the second transmission shaft 34 can simultaneously drive the filter components 20 at the two ventilation openings. The second bevel gears 35 at both ends can respectively mesh with the first bevel gear 234 in the corresponding vibration structure 23.

[0045] Mounting base 36 is fixedly connected to cabinet 10. Second drive shaft 34 is rotatably mounted on mounting base 36, so that second drive shaft 34 can be stably and conveniently mounted on the outside of cabinet 10 and stably perform transmission. Worm gear 33 is located on second drive shaft 34 and meshes with worm 32 for transmission. Worm 32 can be rotatably fixed on cabinet 10. The cooperation between worm gear 33 and worm 32 can make the rotation axis of rotating handle 31 connected to worm 32 perpendicular to the axis of second drive shaft 34. Since the transmission mechanism is arranged on one side of cabinet 10 in the second direction, and the axis of second drive shaft 34 extends along the first direction, the rotation axis of rotating handle 31 can extend along the second direction. This can facilitate the rotation operation of rotating handle 31 on one side of cabinet 10 in the second direction to a certain extent, making it more convenient for maintenance personnel to operate the handle.

[0046] For example, when the filter screen 22 needs to be cleaned, the maintenance personnel can turn the handle 31 so that the second drive shaft 34 can drive the first drive shaft 233 to rotate simultaneously through the second bevel gears 35 at both ends. This allows the filter components 20 of the two vents to self-clean simultaneously through the vibration structure 23, thereby avoiding the need to operate the filter screen 22 at the two vents separately, making the cleaning of the filter screen 22 more convenient and efficient.

[0047] In this embodiment, the two ends of the second transmission shaft 34 are provided with second bevel gears 35 and are connected to the vibration structure 23 in the two filter components 20. This allows the rotating handle 31 to drive the two filter components 20 to perform self-cleaning operations at the same time. This can improve cleaning efficiency while reducing the number of parts in the rotating handle 31 and the transmission mechanism. As a result, the number of parts in the drive component 30 is smaller and the cost is lower, which can further reduce the cost of the electrical cabinet 100.

[0048] In one example of the present invention, such as Figure 2 and Figure 3As shown, the mounting base 36 may include multiple mounting plates 361, which are spaced apart along a first direction. The mounting plates 361 are fixedly connected to the cabinet 10. The second drive shaft 34 passes through the multiple mounting plates 361, and the worm gear 33 is located between two adjacent mounting plates 361.

[0049] In this embodiment, the mounting base 36 is provided with multiple mounting plates 361. The multiple mounting plates 361 are arranged at intervals along the first direction and are fixedly connected to the cabinet 10. For example, the number of mounting plates 361 can be two, three, four, etc. The number of mounting plates 361 can be reasonably set according to the installation and fixing needs. The mounting plates 361 can be welded to the cabinet 10.

[0050] In this embodiment, the drive shaft passes through multiple mounting plates 361, which has a simple structure. The multiple mounting plates 361 can cooperate to provide stable support for the second drive shaft 34. For example, the mounting plate 361 can be provided with a through hole, and the second drive shaft 34 passes through the through hole in the first direction. A bearing structure can be provided in the through hole to reduce the wear of the second drive shaft 34 and make the rotation of the second drive shaft 34 more stable and reliable.

[0051] In this embodiment, the worm gear 33 is disposed between two adjacent mounting plates 361. When the worm gear 32 drives the second transmission shaft 34 to rotate, the two mounting plates 361 can provide more stable support for the transmission shaft, making the rotation of the second transmission shaft 34 more stable and reliable. For example, the worm gear 33 can be arranged in the middle of the second transmission shaft 34, so that the force can be transmitted more evenly to both ends of the second transmission shaft 34, thereby enabling the transmission mechanism to transmit the force more stably and reliably, and enabling the drive assembly 30 to drive the vibration structure 23 to drive the filter screen plate 22 to vibrate and clean more smoothly and reliably.

[0052] In some embodiments of the present invention, such as Figure 6 and Figure 7 As shown, the heat dissipation assembly 40 may also include: a housing 41, a drive motor 43 and a screw 42, a fixed base and a movable plate 44.

[0053] Specifically, the housing 41 extends in the vertical direction and has a mounting groove 411, which is open on one side in the second direction; the drive motor 43 is located on the housing 41, and the screw 42 extends in the vertical direction and is rotatably located in the mounting groove 411. The drive motor 43 is connected to the screw 42 in a transmission manner; the fixed seat is located on the screw 42 and is threadedly engaged with the screw 42; the movable plate 44 is connected to the fixed seat and is limited to the housing 41 in the first direction; and the cooling fan 45 is located on the movable plate 44.

[0054] In this embodiment, the heat dissipation assembly 40 is provided with a housing 41, which extends vertically and can be fixed to the bottom wall of the cabinet 10. The screw 42 is disposed in the mounting groove 411, so that the housing 41 can protect the screw 42, thereby allowing the screw 42 to operate more stably. The drive motor 43 is disposed on the housing 41. The arrangement of the drive motor 43 can be reasonably set according to the transmission connection method with the screw 42. For example, the drive motor 43 can be disposed at the top of the housing 41, and the output shaft of the drive motor 43 can be transmitted to the screw 42 in the vertical direction, thereby driving the screw 42 to rotate. The drive motor 43 drives the screw 42 to rotate, which can avoid manual operation and make the heat dissipation assembly 40 operate stably and efficiently for heat dissipation.

[0055] In this embodiment, the fixed seat is mounted on the screw 42 and threadedly engaged with the screw 42, resulting in a simple structure. The fixed seat can move vertically under the rotation of the screw 42. The movable plate 44 is connected to the fixed seat, and the cooling fan 45 is mounted on the movable plate 44. The movable plate 44 provides an installation position for the cooling fan 45, allowing the cooling fan 45 to be easily mounted on the fixed seat via the movable plate 44. Thus, it can move vertically with the rotation of the screw 42 to perform heat dissipation.

[0056] The mounting slot 411 is open on one side in the second direction, which facilitates the connection between the movable plate 44 and the fixed base. For example, the open side of the mounting slot 411 can be formed on the side of the housing 41 facing the movable plate 44 in the second direction, which makes the heat dissipation assembly 40 easier to assemble. The movable plate 44 and the housing 41 are limited and matched in the first direction, which can effectively prevent the movable plate 44 from rotating during the movement in the vertical direction, so that the movable plate 44 can move stably and reliably in the vertical direction, thereby allowing the cooling fan 45 to perform heat dissipation more stably. For example, the movable plate 44 can abut against the housing 41 in the second direction, that is, the side of the movable plate 44 facing the housing 41 can abut against the opening edge of the mounting slot 411, so that the movable plate 44 can overcome the rotation caused by the rotation of the screw 42 under the abutment support of the housing 41, and the movable plate 44 can move stably in the vertical direction.

[0057] In one embodiment of the present invention, reference is made to... Figure 6 As shown, the movable plate 44 is provided with a receiving groove, which penetrates the movable plate 44 along the second direction. The cooling fan 45 is disposed in the receiving groove. There can be multiple cooling fans 45, which are arranged at intervals along the first direction. There can also be multiple receiving grooves, which are arranged in a one-to-one correspondence with the multiple cooling fans 45.

[0058] In this embodiment, the movable plate 44 is provided with a receiving groove, and the cooling fan 45 is located in the receiving groove. The structure is simple and facilitates the installation and arrangement of the cooling fan 45 on the movable plate 44. There can be multiple cooling fans 45. For example, two, three, four, five, etc., cooling fans 45 can be arranged on the movable plate 44. Multiple cooling fans 45 can be arranged at intervals along the first direction, so as to effectively cover the arrangement range of electrical components in the first direction in the electrical cabinet 100. Thus, multiple cooling fans 45 can move along the up and down direction to fully and stably cover all positions in the cabinet 10 for heat dissipation, effectively reducing heat dissipation blind spots and making the heat dissipation effect of the electrical cabinet 100 better.

[0059] In some embodiments of the present invention, reference is made to Figure 7 As shown, the cabinet 10 has a cavity, and the electrical cabinet 100 may also include a partition frame 50. The partition frame 50 is disposed in the cavity and divides the cavity to form a heat dissipation cavity 101 and an electrical cavity 102. The heat dissipation cavity 101 and the electrical cavity 102 are arranged and connected in a second direction. The heat dissipation component 40 is disposed in the heat dissipation cavity 101, and the vent is connected to the electrical cavity 102.

[0060] In this embodiment, the cabinet 10 has a cavity. The partition frame 50 divides the cavity into a heat dissipation cavity 101 and an electrical cavity 102 that are arranged and connected along the second direction. The structure is simple and can make the heat dissipation component 40 and the electrical components have independent operating spaces, so that the electrical cabinet 100 can operate more stably and reliably. The ventilation port is connected to the electrical cavity 102, so that the electrical cavity 102 can obtain a good natural ventilation and heat dissipation effect, thereby working with the heat dissipation component 40 to make the heat dissipation effect of the electrical cabinet 100 better.

[0061] In one embodiment of the present invention, reference is made to... Figure 7 As shown, the partition frame 50 may be provided with multiple flow holes, which extend along a first direction and penetrate the partition frame 50 in a second direction. The multiple flow holes are arranged at intervals along the vertical direction.

[0062] In this embodiment, the partition frame 50 is provided with multiple flow holes. The multiple fluid holes are arranged in the vertical direction and extend in the first direction. The structure is simple, and the size and number of flow holes can be reasonably arranged according to the needs of heat dissipation and ventilation.

[0063] The following will refer to Figures 1-7 An electrical cabinet 100 with good heat dissipation and dust prevention effect is described according to a specific embodiment of the present invention.

[0064] like Figures 1-7 As shown, the electrical cabinet 100 includes a cabinet body 10, a filter assembly 20, a drive assembly 30, a heat dissipation assembly 40, and a partition frame 50. The cabinet body 10 has a cavity, and the partition frame 50 is disposed in the cavity and divides the cavity into a heat dissipation cavity 101 and an electrical cavity 102. The heat dissipation assembly 40 is disposed in the heat dissipation cavity 101.

[0065] A set of casters 60 is provided at the bottom of the cabinet 10 to meet the movement needs of the electrical cabinet 100. Ventilation openings are formed on both sides of the cabinet 10 in the first direction. The ventilation openings are connected to the electrical cavity 102. There are two filter components 20, which are respectively arranged at the two ventilation openings. The cabinet 10 is provided with a cabinet door 11 on one side in the second direction. The drive component 30 is located on the other side of the cabinet 10 in the second direction.

[0066] The filter assembly 20 includes a filter screen 22, a fixed frame 21, and a vibration structure 23. The vibration structure 23 includes a cam 231, a return spring 232, a fixed plate 235, guide rods 236, a first transmission shaft 233, and a first bevel gear 234. There are two fixed plates 235, which are respectively located at the upper and lower ends of the fixed frame 21 and are fixedly connected to the fixed frame 21. The filter screen 22 is located on the side of the fixed frame 21 away from the vent and is connected to the fixed plate 235 through four guide rods 236. The four guide rods 236 are respectively connected to... At the four corners of the filter screen plate 22, the guide rod 236 passes through the fixed plate 235 and has a limiting part 2361 at one end that is in limiting cooperation with the fixed plate 235. The return spring 232 is sleeved on the guide rod 236 and its two ends are fixedly connected to the filter screen plate 22 and the fixed plate 235 respectively. The first drive shaft 233 extends along the second direction. One end of the first drive shaft 233 is connected to the cam 231 and the other end extends out of the fixed frame 21 and is connected to the first bevel gear 234. The cam 231 is located in the fixed frame 21 and is opposite to the center position of the filter screen plate 22 in the first direction.

[0067] The drive assembly 30 includes a mounting base 36, a rotating handle 31, a worm 32, a worm wheel 33, a second drive shaft 34, and a second bevel gear 35. The second drive shaft 34 extends along a first direction and has a second bevel gear 35 at each end. The second bevel gear 35 meshes with a first bevel gear 234. The second drive shaft 34 is rotatably fixed to the cabinet 10 via the mounting base 36. The mounting base 36 includes two mounting plates 361, which are spaced apart along the first direction. The worm wheel 33 is located on the second drive shaft 34 and between the mounting plates 361. The worm wheel 33 is located in the middle of the second drive shaft 34. The worm 32 is rotatably fixed to the cabinet 10 and connected to the rotating handle 31. The worm wheel 33 meshes with the worm 32.

[0068] The heat dissipation assembly 40 includes a housing 41, a drive motor 43, a screw 42, a fixed base, a movable plate 44, and a heat dissipation fan 45. The housing 41 is fixed to the bottom wall of the heat dissipation cavity 101 and extends in the vertical direction. The screw 42 is located in the mounting groove 411 of the housing 41 and extends in the vertical direction. The drive motor 43 is located at the upper end of the housing 41 and is connected to the screw 42 for transmission. The fixed base is threadedly engaged with the screw 42. The movable plate 44 is connected to the fixed base. There are two heat dissipation fans 45, which are arranged and installed on the movable plate 44 in a first direction.

[0069] When the electrical cabinet 100 is running, if the filter screen 22 needs cleaning, the maintenance personnel can turn the handle 31 to rotate the worm gear 32, causing the worm wheel 33 to drive the second transmission shaft 34 to rotate, which in turn causes the second bevel gear 35 to rotate. The first bevel gear 234, which meshes with the second bevel gear 35, rotates, driving the first transmission shaft 233 to rotate, which in turn causes the cam 231 to rotate. During the rotation of the cam 231, the filter screen 22 is periodically squeezed. Under the guidance of the guide rod 236 and the elastic force of the return spring 232, the filter screen 22 reciprocates in the first direction. This vibration causes the filter screen 22 to vibrate, thereby shaking off the dust and debris attached to the surface of the filter screen 22, achieving self-cleaning. The method of turning the handle 31 allows for convenient manual operation to drive the entire filter assembly 20 and the drive assembly 30 to cooperate in cleaning operations. This effectively prevents the filter screen 22 from becoming clogged during long-term use, which would affect the airflow tube and filtration effect, and reduces the amount of dust entering the cabinet 10, thereby reducing the risk of electrical component failure due to dust.

[0070] In this embodiment, the filter screen 22 can be cleaned by turning the handle 31. The operation is simple and convenient, and there is no need to disassemble the filter screen 22, which saves manpower and time costs. This makes the cleaning of the filter screen 22 more convenient and efficient, and makes the maintenance of the electrical cabinet 100 easier and more cost-effective.

[0071] When the heat dissipation component 40 is in operation, the drive motor 43 starts, driving the screw 42 to rotate. The movable plate 44 connected to the screw 42 moves up and down along the screw 42 under the constraint of the housing 41, thereby causing the heat dissipation fan 45 to move accordingly. During the movement, the airflow generated by the heat dissipation fan 45 can cover a wider area inside the cabinet 10, dissipating heat from electrical components in different locations, effectively preventing the formation of local high temperatures. This effectively dissipates mechanical energy from areas with complex structures and uneven distribution of electrical components inside the cabinet 10. At the same time, outside air enters the cabinet 10 after being filtered by the filter plate 22. Under the action of the heat dissipation fan 45, the hot air in the cavity is discharged from the cabinet 10, thus forming a good air circulation. This significantly improves the overall heat dissipation effect of the electrical cabinet 100, ensuring that the electrical components operate at a suitable temperature and extending the service life of the electrical components to a certain extent.

[0072] In this embodiment, by setting up a filter assembly 20 and a drive assembly 30, the rotating handle 31 of the drive assembly 30 is connected to the vibration structure 23 of the filter assembly 20 through a transmission mechanism. This allows the filter screen 22 to shake off accumulated dust and debris under the driving action of the rotating handle 31, thus achieving self-cleaning without the need for manual removal and cleaning. This makes cleaning the filter screen 22 more efficient and convenient, thereby effectively reducing the probability of vent blockage. At the same time, the cooling fan 45 of the heat dissipation assembly 40 is movably installed in the cabinet 10 in the vertical direction, so that electrical components in all positions in the cabinet 10 can be cooled by the cooling fan 45, effectively reducing heat dissipation blind spots, improving the heat dissipation effect of the electrical cabinet 100, and reducing the cost of the electrical cabinet 100.
