Description

Technical Field

[0001] This invention belongs to the field of switchgear technology, specifically relating to a switchgear with intelligent temperature monitoring function. Background Technology

[0002] As a key electrical device in the power generation, transmission, distribution and energy conversion process of a power system, the core function of switchgear is to control the opening and closing of electrical equipment and provide safety protection. Its wiring logic is that the external line is first connected to the main control switch in the cabinet, and then distributed to each sub-control switch. Subsequently, relevant components can be flexibly configured according to the actual needs of different branches.

[0003] During operation, switchgear generates Joule heat due to the current flowing through conductors. If this heat cannot be dissipated in time, the temperature will continue to rise, affecting the accuracy of temperature monitoring data, accelerating the wear and tear of electrical components, shortening equipment lifespan, and potentially causing equipment failure. Therefore, ventilation and heat dissipation are key technical requirements in switchgear design.

[0004] Existing switchgear typically has ventilation openings on the side walls or doors of the cabinet to allow for air convection and heat dissipation. To prevent external dust and debris from entering the cabinet through these openings and affecting the insulation performance and normal operation of electrical components, some switchgear is equipped with dust filters at the ventilation openings. However, existing technology has the following drawbacks: Firstly, the structure of the ventilation openings is mostly fixed, and the ventilation area cannot be adjusted according to changes in the cabinet temperature or actual heat dissipation needs—when the temperature inside the cabinet is high, the heat dissipation efficiency of the fixed ventilation area is insufficient, making it difficult to quickly reduce the temperature.

[0005] On the other hand, electronic components and busbars inside the switchgear generate a small amount of residual heat even under low load, naturally maintaining the cabinet temperature slightly higher than the outside temperature. If the ventilation area is too large, a large amount of cold outside air will rush in quickly, rapidly carrying away the small amount of residual heat inside the cabinet, causing the cabinet temperature (including the surface temperature of components) to drop below the air dew point temperature. This causes moisture in the air inside the cabinet to condense on the surface of the components, seriously threatening the insulation performance and operational safety of the electrical components. To address this issue, we propose a switchgear with intelligent temperature monitoring to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a switch cabinet with intelligent temperature monitoring function. During use, the area of ​​the arc-shaped ventilation opening can be adjusted according to different usage needs to dynamically adjust the ventilation effect and achieve a balance between heat dissipation and reducing the risk of condensation.

[0023] The beneficial effects of this invention are:

[0024] I. Intelligent Adaptability and Precise Balance Between Heat Dissipation and Anti-Condensation: Utilizing a dew point algorithm with dual temperature and humidity monitors and a controller, a closed-loop control system is achieved, from condensation risk prediction to dynamic adjustment of ventilation area. Anti-condensation is prioritized to adapt to different load conditions. Under low-risk conditions, ventilation and air supply efficiency are maximized; under high-risk conditions, a small ventilation volume plus a trace of residual heat is maintained to ensure temperature control, resolving the contradiction of choosing between heat dissipation and condensation caused by fixed ventilation in traditional switchgear. Motor speed and ventilation area are linked for control; for example, the first motor speed control controls the sealing plate, and the second motor speed control controls the fan blades, achieving stepless adaptation between low-speed anti-condensation and high-speed strong heat dissipation, covering the needs of all scenarios from low to high loads.

[0025] II. Superior Functional Integration: A single power source allows for reuse in multiple scenarios. The second motor simultaneously drives heat dissipation and triggers dust cleaning, eliminating the need for an additional dust cleaning motor, simplifying the overall structure and reducing energy consumption. The cleaning mechanism and heat dissipation mechanism are linked, automatically switching operating conditions during dust cleaning without manual intervention. Modular design reduces maintenance costs; the cleaning blocks and brushes are modular components, allowing for individual replacement of worn parts without overall disassembly. The vertically arranged cleaning components cover the entire cabinet area, adapting to curved cabinet structures and avoiding cleaning blind spots. Attached Figure Description

Detailed Implementation

[0042] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0043] Example 1:

[0044] like Figure 1-14 As shown, a switch cabinet with intelligent temperature monitoring function according to the present invention includes...

[0045] The curved cabinet 1 has a bottom plate 101 at the bottom, a closed door 11 on the front side, and several curved ventilation openings 12 evenly distributed from top to bottom on the rear side of the curved cabinet 1. Curved dustproof heat dissipation plates 13 are fixedly installed inside the several curved ventilation openings 12. Curved grooves 14 are opened on the upper inner wall of the several curved ventilation openings 12. An assembly plate 15 is provided in the center of the interior of the curved cabinet 1.

[0046] The arc-shaped sealing plate 2 is provided in several pieces, and the arc-shaped sealing plates 2 are respectively slidably sealed and assembled inside the arc-shaped grooves 14;

[0047] The first drive mechanism 3 is installed on one side of the arc-shaped cabinet 1 and is used to drive several arc-shaped sealing plates 2 to rise or fall.

[0048] There are two temperature and humidity monitors 4, one inside the curved cabinet 1 and the other on the outer wall.

[0049] The controller 5 is installed on the front side of the closed door 11. The two temperature and humidity monitors 4 and the first drive mechanism 3 are all electrically connected to the controller 5.

[0050] First, after the equipment is started, the temperature and humidity monitoring instrument 4 installed inside the curved cabinet 1 will collect the temperature and relative humidity data of the surrounding electrical components such as electronic components and busbars in real time. At the same time, another temperature and humidity monitoring instrument 4 installed on the outer wall of the curved cabinet 1 will collect the temperature and relative humidity data of the external environment. The two monitoring instruments will continuously and stably transmit the collected real-time data to the controller 5 fixedly installed on the front side of the closed door 11.

[0051] The controller 5 has a built-in mature dew point temperature calculation algorithm. Any existing algorithm that meets the usage requirements can be selected. After receiving dual temperature and humidity data, the controller 5 will immediately combine the two to perform comprehensive calculations and accurately determine the dew point temperature of the outside air, which serves as the core basis for judging the risk of condensation. At the same time, the controller 5 has pre-set anti-condensation thresholds and heat dissipation thresholds. After completing the dew point temperature calculation, the controller 5 will compare the real-time temperature inside the cabinet with these two thresholds respectively. Following the core control principle that anti-condensation takes precedence over heat dissipation, the controller will generate corresponding ventilation area adjustment commands and transmit the commands to the first drive mechanism 3 installed on one side of the curved cabinet 1.

[0052] After receiving the command, the first drive mechanism 3 will drive several arc-shaped sealing plates 2, which are respectively slidably and sealed in the arc-shaped groove 14 on the inner wall of the arc-shaped vent 12, to make stable upward or downward movements along the arc-shaped groove 14. By changing the occlusion range of the arc-shaped sealing plate 2 on the arc-shaped vent 12, the effective ventilation area of ​​the arc-shaped vent 12 can be precisely adjusted.

[0053] When the controller 5 determines that the real-time temperature inside the cabinet is close to the calculated dew point temperature and there is a risk of condensation, it will control the first drive mechanism 3 to drive the arc-shaped sealing plate 2 to a suitable position, maintain a small opening and closing degree, and keep the arc-shaped vent 12 in a small ventilation area state. At this time, only a small amount of outside air can slowly enter the cabinet through the arc-shaped dustproof heat dissipation plate 13 fixedly installed inside the arc-shaped vent 12. This avoids a large influx of low-temperature and high-humidity air, and also relies on the small amount of residual heat generated by the electrical components on the assembly plate 15 even when operating at low load to maintain the temperature inside the cabinet slightly higher than the outside temperature, preventing water vapor from condensing into dew on the surface of the components.

[0054] When the controller 5 detects that the real-time temperature inside the cabinet is slightly higher than the anti-condensation threshold but has not reached the preset heat dissipation threshold, and the temperature difference between the inside and outside of the cabinet is small, it will activate the dynamic adjustment mode. The first drive mechanism 3 will flexibly control the lifting height of the arc-shaped sealing plate 2 and adjust the ventilation area of ​​the arc-shaped vent 12 in real time to match the ventilation volume with the slight heat dissipation demand inside the cabinet. Under the premise of ensuring that no condensation occurs, it will achieve gentle ventilation and heat dissipation and avoid heat accumulation inside the cabinet. When the controller 5 detects that the temperature inside the cabinet continues to rise and reaches or exceeds the heat dissipation threshold, or the temperature difference between the inside and outside of the cabinet is large and the heat dissipation demand is urgent, it will immediately issue a maximum ventilation command and control the first drive mechanism 3 to drive the arc-shaped sealing plate 2 to rise completely and no longer block the arc-shaped vent 12, so that it maintains the maximum ventilation area. At this time, the outside air can be filtered by the arc-shaped dustproof heat dissipation plate 13 and quickly flow into the cabinet in a highly efficient convection manner, fully exchange with the high temperature air inside the cabinet, achieve rapid cooling, and ensure that the electrical components operate within a safe temperature range.

[0055] When the risk of condensation is high during use, the dual temperature and humidity monitors 4 and controller 5 work together to drive the arc-shaped sealing plate 2 to rise and fall, thereby achieving adaptive adjustment of the ventilation area of ​​the arc-shaped vent 12. This precisely solves the problem of insufficient heat dissipation and the coexistence of condensation risk caused by the fixed ventilation area in the existing technology, and adapts to the usage needs under different load conditions. At the same time, it follows the control principle of prioritizing anti-condensation over heat dissipation, using the anti-condensation threshold as the safety bottom line, and then matching the heat dissipation needs. When heat dissipation is required, controller 5 will first use the dual temperature and humidity monitors 4 to determine whether there are condensation causes in the outside environment due to high humidity and low temperature. If the risk is high, the arc-shaped vent 12 will be enlarged to meet the basic heat dissipation level, rather than being maximized. If the risk is low, the vent will be fully opened to achieve efficient heat dissipation.

[0056] This design avoids the contradiction of sacrificing anti-condensation for heat dissipation, prioritizing the prevention of fatal damage to electrical components caused by condensation. At the same time, by dynamically adjusting the ventilation area, it prevents excessively high temperatures inside the cabinet from affecting the equipment's lifespan, providing double protection for the safe operation of the switchgear.

[0057] During use, the controller 5 sends forward / reverse or stop commands to the first motor 38 based on the data collected by the dual temperature and humidity monitors 4 and the working condition judgment results. The first motor 38 is fixedly installed on the top of the assembly box 32 on the top left side of the arc-shaped cabinet 1. Its output shaft is rotatably connected to the lead screws 31 at the top of the base plate 101 and the bottom of the assembly box 32, respectively, driving the lead screws 31 to rotate synchronously.

[0058] Since the adjusting blocks 34 fixedly installed on the left side of several arc-shaped sealing plates 2 are all provided with threaded through holes that are threadedly connected to the lead screw 31, and the adjusting blocks 34 are slidably connected to the strip-shaped through groove 33 opened on the left inner wall of the arc-shaped groove 14, and simultaneously slidably engaged with the stabilizing rod 37 fixedly installed between the base plate 101 and the assembly box 32, when the lead screw 31 rotates, it will drive all the adjusting blocks 34 to rise or fall synchronously along the lead screw 31 and the stabilizing rod 37, thereby driving the arc-shaped sealing plates 2 to slide along the arc-shaped groove 14, so as to achieve precise adjustment of the ventilation area of ​​the arc-shaped ventilation opening 12. The distance sensor 35 installed on the side of the lowest adjusting block 34 away from the curved cabinet 1 will detect the lifting distance of the adjusting block 34 in real time and feed the data back to the controller 5 to form a closed-loop control to ensure the accuracy of ventilation area adjustment. At the same time, the first telescopic dust cover 36 between each two adjacent adjusting blocks 34, and the second telescopic dust cover between the uppermost and lowermost adjusting blocks 34 and the base plate 101 and assembly box 32 will extend and retract synchronously with the movement of the adjusting block 34, always covering the lead screw 31 and preventing dust and debris from entering the transmission structure.

[0059] In this way, the threaded transmission of the lead screw 31 and the adjusting block 34, combined with the guide limit of the stabilizer 37, and the closed-loop feedback of the ranging sensor 35 and the controller 5, can achieve precise control of the lifting height of the arc-shaped sealing plate 2, thereby ensuring the accuracy of the ventilation area adjustment of the arc-shaped ventilation opening 12 and adapting to the precise ventilation needs under different working conditions; the first motor 38 drives smoothly, avoiding jamming or deviation during the adjustment process.

[0060] Example 2:

[0061] Based on Embodiment 1, a further improvement is made: a hollow assembly column 6 is fixedly installed on the top left side of the arc-shaped cabinet 1, and several heat dissipation mechanisms are arranged vertically on the right side of the hollow assembly column 6.

[0062] The heat dissipation mechanism includes a rotating shaft, which is rotatably mounted on the right side of the hollow mounting column 6. A drive platform 62 is fixedly installed on the right end of the rotating shaft. Several fan blades 63 are arranged around the drive platform 62. A protective frame 64 matching the position of the fan blades 63 is fixedly installed on the right side of the hollow mounting column 6. A rotating rod 65 is rotatably mounted on the upper and lower inner walls of the arc-shaped cabinet 1. Several first bevel gears 66 are arranged vertically around the rotating rod 65. One end of several rotating shafts extends into the hollow mounting column 6 and is fixedly mounted with a second bevel gear 67 that meshes with the first bevel gears 66. A second drive mechanism 7 is installed on the upper inner wall of the arc-shaped cabinet 1 to drive the rotating rod 65 to rotate.

[0063] During operation, the second drive mechanism 7 provides power to drive the rotating rods 65 installed on the inner walls of the upper and lower sides of the arc-shaped cabinet 1 to rotate; several first bevel gears 66 arranged vertically around the rotating rods 65 rotate synchronously, and drive the matching second bevel gears 67 to rotate through gear meshing, thereby driving the rotating shaft fixedly connected to the second bevel gears 67 to rotate; the drive platform 62 fixedly installed on the right end of the rotating shaft and several fan blades 63 surrounding it rotate synchronously, generating directional airflow, which, together with the air convection of the arc-shaped ventilation opening 12, achieves rapid heat dissipation inside the cabinet; the protective frame 64 installed on the right side of the hollow assembly column 6 It can protect the fan blades 63 from damage caused by external impacts; the entire heat dissipation mechanism is integrated into the top left side of the arc-shaped cabinet 1 through the hollow assembly column 6, with several heat dissipation mechanisms arranged vertically to achieve uniform heat dissipation in different height areas inside the cabinet; this heat dissipation mechanism can be linked with the arc-shaped vent 12 and the arc-shaped sealing plate 2, and through active air supply combined with passive ventilation, it enhances the air convection effect and more efficiently meets the heat dissipation requirements under high load conditions. At the same time, the arc-shaped structure of the arc-shaped cabinet 1 allows for smoother airflow and reduces the impact of dead corners on heat dissipation. In conjunction with the controller 5, when the temperature inside the cabinet far exceeds the heat dissipation threshold and the risk of condensation is low, At any time, the controller 5 outputs different current or pulse signals to control the speed of the second drive mechanism 7: when maximizing heat dissipation is required, the gear transmission chain drives the rotating rod 65 to rotate rapidly, so that multiple sets of fan blades 63 rotate at full load, maximizing the active air supply efficiency; when the temperature inside the cabinet is close to the heat dissipation threshold or the risk of condensation increases, the controller 5 gradually reduces the speed of the second drive mechanism 7, and the air supply intensity of the fan blades 63 is reduced accordingly. With the reduced ventilation area, condensation is avoided while meeting basic heat dissipation requirements; under low-load anti-condensation conditions, the controller 5 controls the second drive mechanism 7 to operate at low speed intermittently, and the fan blades 63 maintain a weak airflow to prevent local air stagnation inside the cabinet.

[0064] The second drive mechanism 7 includes a first large gear 71 and a power component. The first large gear 71 is rotatably mounted on the center of the upper inner wall of the arc-shaped cabinet 1. A first small gear 72, meshing with the first large gear 71, is rotatably mounted on the upper inner wall of the arc-shaped cabinet 1. A second large gear 73 is fixedly mounted at the bottom of the first small gear 72. A third large gear 74 is rotatably mounted on the left side of the upper inner wall of the arc-shaped cabinet 1. A second small gear 75, meshing with the second large gear 73, is fixedly mounted at the bottom of the third large gear 74. A third small gear 76, meshing with the third large gear 74, is rotatably mounted on the upper inner wall of the arc-shaped cabinet 1. A first transmission wheel 77 is fixedly mounted at the bottom of the third small gear 76. A second transmission wheel 78 is fixedly mounted around the circumference of the rotating rod 65. A synchronous belt 79 is installed between the first transmission wheel 77 and the second transmission wheel 78 for common transmission. The power component is mounted on the top of the arc-shaped cabinet 1 and is used to drive the first large gear 71 to rotate. The power component is electrically connected to the controller 5. A protective box 791 is fixedly mounted on the upper inner wall of the arc-shaped cabinet 1.

[0065] When the second drive mechanism 7 is in use, the power component electrically connected to the controller 5 provides driving force to drive the first large gear 71, which is mounted on the center of the upper inner wall of the arc-shaped cabinet 1, to rotate.

[0066] The first large gear 71 drives the first small gear 72 that is matched with it to rotate through gear meshing. The second large gear 73, which is fixed at the bottom of the first small gear 72, rotates synchronously, thereby meshing and driving the second small gear 75 at the bottom of the third large gear 74 to rotate. The third large gear 74 then drives the third small gear 76 to rotate through meshing.

[0067] The first transmission wheel 77, which is fixed at the bottom of the third pinion 76, rotates together with it. Through the transmission action of the synchronous belt 79, the power is transmitted to the second transmission wheel 78, which is fixed around the circumference of the rotating rod 65, and finally drives the rotating rod 65 to rotate stably, providing rotational power for the fan blades 63 of the heat dissipation mechanism.

[0068] Throughout the transmission process, the protective box 791 fixedly installed on the inner wall of the upper side of the arc-shaped cabinet 1 forms a closed protection for all gears, transmission wheels and synchronous belts 79 to avoid external interference;

[0069] Meanwhile, the controller 5 can adjust the output speed of the power component according to the working conditions. Through the fixed matching of the gear transmission ratio, the speed of the rotating rod 65 can be precisely controlled, thereby synchronously adjusting the air delivery intensity of the fan blade 63.

[0070] This design minimizes power loss during gear meshing transmission. Combined with the flexible transmission characteristics of the synchronous belt 79, it ensures efficient power transmission while buffering impacts during transmission, preventing component wear caused by rigid connections. The multi-gear cooperative transmission structure disperses stress points, improves the overall stability of the transmission system, and reduces the risk of malfunctions such as jamming and breakage. Furthermore, based on gear transmission characteristics, when the large gear drives the small gear to rotate, the speed of the small gear at the output end will be higher than the speed of the large gear at the input end, and the transmission ratio is inversely proportional to the gear tooth ratio.

[0071] After the power component drives the first large gear 71 to rotate, the power is transmitted sequentially through three sets of gears meshing from large to small, and the speed is amplified step by step. Finally, the third small gear 76 drives the first transmission wheel 77, and then transmits it to the rotating rod 65 through the synchronous belt 79. This achieves the speed increase effect of the power component from low speed input to high speed output of the rotating rod 65. This multi-stage speed increase design can match the operating requirements of the heat dissipation mechanism.

[0072] The power assembly includes an assembly platform 8, which is fixedly installed on the top of the arc-shaped cabinet 1. An assembly slot 81 is provided inside the assembly platform 8. A drive shaft is fixedly installed on the top of the first large gear 71. The upper end of the drive shaft extends into the assembly slot 81 and is fixedly installed on a disc 82. A circular groove 83 is provided on the top of the disc 82. Several meshing teeth 841 are arranged around the periphery of the circular groove 83. A drive block 84 is rotatably assembled inside the circular groove 83. Several sliding grooves 851 are arranged around the periphery of the drive block 84. A slider 86 is slidably assembled inside each of the sliding grooves 851. A first spring 87 is provided between the slider 86 and the inner wall of the sliding groove 851. Several sliders 86 mesh with several meshing teeth 841. An inclined surface 88 is provided on one side of each slider 86. A second motor 89 is provided on the top of the assembly platform 8. The output shaft of the second motor 89 is connected to the center of the top of the drive block 84. The second motor 89 is electrically connected to the controller 5.

[0073] When the power unit is running, the controller 5 sends a directional rotation command to the second motor 89 according to the temperature and humidity conditions and heat dissipation requirements inside the cabinet. When the second motor 89 rotates in the preset driving direction, its output shaft will drive the drive block 84 to rotate synchronously in the same direction. The slider 86 in the peripheral groove 851 of the drive block 84 will be kept in a meshing state with the meshing teeth 841 of the circular groove 83 of the disk 82 under the elastic support of the first spring 87, thereby driving the disk 82 to rotate through the meshing action. The disk 82 transmits power to the first large gear 71 through the drive shaft at the bottom, and finally drives the gear transmission group of the second drive mechanism 7 to operate, providing power for the heat dissipation mechanism.

[0074] When the second motor 89 rotates in the opposite direction, the drive block 84 rotates in the opposite direction as well. At this time, the inclined surface 88 on one side of the slider 86 will contact the meshing teeth 841. The force applied by the meshing teeth 841 will push the slider 86 along the inclined surface 88 to overcome the elastic force of the first spring 87, slide into the groove 851 and disengage from the meshing teeth 841. The reverse rotation of the drive block 84 cannot be transmitted to the disk 82, and the first large gear 71 and subsequent transmission structure stop operating. Throughout the process, the controller 5 can adjust the rotation speed of the drive block 84 by adjusting the speed of the second motor 89, thereby regulating the operating speed of the disk 82 and subsequent transmission mechanism to match different heat dissipation requirements.

[0075] In this way, the second motor 89 is electrically connected to the controller 5 during use, and the speed can be steplessly or steppedly adjusted according to the changes in the risk of condensation and heat dissipation requirements in the cabinet. With the unidirectional transmission structure, while effectively transmitting power, it can accurately control the rotation speed of the disc 82, thereby adjusting the air supply intensity of the fan blades 63 of the heat dissipation mechanism, and achieving precise adaptation between low-speed anti-condensation and high-speed strong heat dissipation.

[0076] Example 3:

[0077] Based on Embodiment 2, a further improvement is made: a frustum 9 is fixedly installed on the upper inner wall of the assembly groove 81; a through hole is opened at the top of the frustum 9 for the output shaft of the second motor 89 to pass through; a ring 91 is fitted around the frustum 9; a driving block 92 is eccentrically mounted on the top of the driving block 84; a vertical groove is opened at the top of the driving block 92; rollers 93 are mounted on the front and rear sides of the vertical groove and rotate together; the rollers 93 are silent rollers; an arc-shaped triangular ramp 94 is provided at the bottom of the ring 91; a contact sensing element 95 is fixedly installed on one vertical surface of the arc-shaped triangular ramp 94; an arc-shaped opening 96 is opened around the assembly table 8 and communicates with the circular groove 83; a crossbar 97 is fixed around the arc-shaped triangular ramp 94; a cleaning mechanism 98 is installed at the end of the crossbar 97 away from the frustum 9.

[0078] In this way, when the switch cabinet is in normal heat dissipation condition, the second motor 89 rotates in the forward direction, driving the drive block 84 to rotate in the forward direction synchronously. At this time, the drive block 84 transmits power to the disc 82 to drive the fan blade 63 to rotate through the engagement of the slider 86 and the meshing teeth 841. At the same time, the eccentric drive block 92 at the top of the drive block 84 rotates in the forward direction, driving the roller 93 to roll in the forward direction on the track path of the ring 91. The track adopts a staggered design, and when rolling in the forward direction, the roller 93 will avoid the vertical surface of the arc-shaped triangular inclined platform 94 and will not contact the contact sensing element 95, so the dust removal mechanism remains stationary.

[0079] When the arc-shaped dustproof heat sink 13 needs to be cleaned, the controller 5 sends a cleaning command to the second motor 89, which switches to reverse rotation. At this time, the slider 86 around the drive block 84 disengages from the engagement of the inclined surface 88 and the meshing teeth 841, and the power cannot be transmitted to the disc 82. The fan blade 63 stops rotating to avoid dust. At the same time, the drive block drives the drive block 92 to rotate in the opposite direction, and the roller 93 rolls in the opposite direction on the track. It will fall precisely into the area of ​​the misaligned structure and abut against the vertical surface of the arc-shaped triangular inclined platform 94, triggering the contact sensor element 95 installed on the vertical surface. After the contact sensor element feeds back a signal to the controller 5, the controller controls the second motor 89 to drive the drive block to rotate at a specific angle. Through the crossbar 97, the cleaning mechanism 98 moves along the arc-shaped opening 96 to complete the cleaning of the arc-shaped dustproof heat sink 13. After the cleaning is completed, the second motor resets, the roller 93 moves away from the misaligned area with the forward rotation, and the equipment returns to the normal heat dissipation mode.

[0080] This staggered structure of the 91-ring track achieves a functional distinction between forward-driven heat dissipation and reverse-triggered dust cleaning, allowing for automatic switching of operating conditions without additional control components. When rotating in the reverse direction, the fan blade power is automatically cut off to avoid dust interference during dust cleaning. At the same time, the vertical surface of the staggered area precisely triggers the sensing element, ensuring the accuracy of the dust cleaning action, thus balancing structural simplicity and operational reliability.

[0081] The cleaning mechanism 98 includes several cleaning components, which are arranged vertically and assembled around the periphery of the arc-shaped cabinet 1. Each cleaning component includes an arc-shaped rod 981, which is fixedly connected to the periphery of the arc-shaped cabinet 1 by two fixed rods 989. A cleaning block 982 is slidably mounted around the periphery of the arc-shaped rod 981. A scraping component is installed on the side of the cleaning block 982 near the arc-shaped cabinet 1. An arc-shaped spring 99 is sleeved around the periphery of the arc-shaped rod 981. One end of the arc-shaped spring 99 is fixedly connected to the side wall of the cleaning block 982, and the other end of the arc-shaped spring 99 is fixedly connected to the periphery of the fixed rod 989.

[0082] A vertical block 983 is fixedly installed on the side of several cleaning blocks 982 away from the curved cabinet 1. The top of the vertical block 983 is provided with a displacement groove 984. A connecting rod 985 is fixedly installed on the end of the horizontal bar 97 away from the truncated cone 9, which is slidably connected to the displacement groove 984. A silent slide rail is installed inside the displacement groove 984 and slides with the connecting rod 985.

[0083] When the cleaning mechanism 98 is not in the dust-cleaning state, the connecting rod 985 at the end of the horizontal bar 97 slides up and down only in the displacement groove 984 at the top of the vertical block 983, and the vertical block 983 and several cleaning blocks 982 remain stationary, which does not affect the normal operation of the switch cabinet.

[0084] When dust removal is required, the controller 5 controls the second motor 89 to drive the horizontal bar 97 to rotate, and the connecting rod 985 will pull the vertical block 983 to make a deflection displacement at a specific angle, which will simultaneously drive several vertically arranged cleaning blocks 982 to slide along the periphery of the arc-shaped rod 981.

[0085] When in use, the scraping component of the cleaning block 982 near the side of the curved cabinet 1 will adhere to the surface of the curved dustproof heat dissipation plate 13 and complete the dust removal as the cleaning block slides; at the same time, the curved spring 99 sleeved around the curved rod 981 will extend and retract as the cleaning block slides, and drive the cleaning block to return to its original position after the dust removal is completed; since several cleaning components are arranged vertically and the cleaning block 982 is modularly designed, it can cover different height areas around the curved cabinet 1, which can clean the areas not covered by the curved sealing plate 2, and can also meet the dust removal needs of local areas covered by the curved sealing plate.

[0086] As the scraping assembly slides with the cleaning block 982, the fixing block 986, under the elastic support of the second spring 987, drives the cleaning brush 988 to fit tightly against the surface of the arc-shaped dustproof heat dissipation plate 13. When the cleaning brush contacts the uneven area of ​​the heat dissipation plate or the area with thicker dust accumulation, the fixing block 986 slides along the adjustment groove on the cleaning block 982, and the second spring 987 extends and retracts synchronously, adaptively adjusting the contact angle and pressure of the cleaning brush to ensure that the cleaning brush always makes full contact with the surface of the heat dissipation plate, and completes comprehensive dust removal as the cleaning block slides.
