Description

Technical Field

[0001] This invention belongs to the field of heat dissipation equipment technology, and in particular relates to a rapid heat dissipation device for high-voltage cabinets and its usage method. Background Technology

[0002] A high-voltage switchgear is a type of electrical equipment. External power lines first enter the main control switch inside the cabinet, then the branch control switches, with each branch configured according to its needs. These branch switches can contain instruments, automatic control components, motor magnetic switches, and various AC contactors. Because many components are integrated inside the high-voltage switchgear, a large amount of heat is generated internally, which needs to be dissipated promptly to ensure the components operate within their normal temperature range. Current high-voltage switchgear typically uses dust filters combined with cooling fans for heat dissipation. However, prolonged use of dust filters can easily lead to blockage, resulting in poor heat dissipation. Therefore, to ensure efficient heat dissipation and ventilation, frequent manual cleaning or replacement of the dust filters is necessary. This operation is time-consuming and labor-intensive, affecting the efficiency of the heat dissipation mechanism, the continuity of heat dissipation work, and ultimately, the overall efficiency of heat dissipation. Summary of the Invention

[0003] To address the problems existing in the prior art, this invention provides a rapid heat dissipation device and method for use in high-voltage switchgear. It features a heat dissipation component linked to a dust removal component, sharing power, simplifying the structure, and operating synchronously to improve heat dissipation and dust removal efficiency. Furthermore, the winding component moves the filter belt, enabling automatic replacement that saves time and effort. Combined with the cleaning component's double-sided dust sweeping and the dust removal component's extraction, it ensures continuous heat dissipation and effectively improves heat dissipation efficiency. This invention solves the problem in the prior art where dust filters easily become clogged after prolonged use, requiring frequent manual cleaning or replacement to maintain heat dissipation and ventilation efficiency. This is time-consuming and labor-intensive, affecting the efficiency of the heat dissipation mechanism, the continuity of heat dissipation work, and ultimately, the overall efficiency of heat dissipation.

[0004] This invention is implemented as follows: a rapid heat dissipation device for a high-voltage switchgear includes a housing. A rain shield is fixed to the top of the housing. Heat dissipation vents are fixedly connected to both sides of the housing. A partition is fixedly connected inside the housing. Components are fixedly installed on the top of the partition. Heat dissipation components are installed inside the housing corresponding to the heat dissipation vents. A dust removal component is installed on the housing below the heat dissipation component on the left side, located below the partition. Cleaning components are installed at the bottom of the partition and on the inner bottom of the housing. Rewinding components are installed on both outer walls of the housing. Each rewinding component includes a rewinding frame, with a filter belt wound between the two rewinding frames. The filter belt fits against the heat dissipation vents and passes through the housing between the cleaning components. The heat dissipation component dissipates and ventilates the heat generated by the components. The filter belt filters dust at the heat dissipation vents. The rewinding component moves the filter belt around its winding mechanism. The cleaning component cleans the dust and impurities on the filter belt. The dust removal component exhausts the impurities that fall off during the sweeping process.

[0005] In a preferred embodiment of the present invention, the heat dissipation assembly includes a heat dissipation fan, a support frame is fixedly connected to the top of the partition, a heat dissipation motor is fixedly installed on the top of the support frame, a heat dissipation shaft is fixedly connected to the output end of the heat dissipation motor, the heat dissipation fan is fixedly connected to the end of the heat dissipation shaft, and a drive wheel is sleeved and fixed on the heat dissipation shaft.

[0006] This design allows the cooling motor to drive the cooling shaft, which in turn rotates the cooling fan. This creates a directional airflow within the enclosure, quickly directing the heat generated by the components during operation to the heat dissipation vents for exhaust, significantly improving heat dissipation efficiency. The drive wheel can also rotate the subsequent dust removal components, allowing the cooling and dust removal components to share the same power source. This simplifies the overall structure of the device, reduces energy consumption, and ensures the synchronization of cooling and dust removal actions. The support frame provides fixed support for the cooling motor and the cooling shaft.

[0007] In a preferred embodiment of the present invention, the dust removal assembly includes a dust removal fan and a dust removal pipe. A support plate is fixedly connected to the inner bottom of the housing. A dust removal shaft is connected to the end side wall of the support plate via a bearing. The dust removal fan is fixedly connected to the end of the dust removal shaft. A driven wheel one is sleeved and fixed on the dust removal shaft. A support shaft is connected to the left inner wall of the housing via a bearing. A driven wheel two and a driven wheel three are sleeved and fixed on the support shaft. The driven wheel one and the driven wheel two are connected by a vertical transmission belt. The vertical transmission belt slides through the partition. The driving wheel and the driven wheel three are connected by a horizontal transmission belt.

[0008] With this setup, the active wheel of the heat dissipation component drives the driven wheel and the dust removal shaft to rotate via a horizontal transmission belt, driven wheel three, support shaft, driven wheel two, and vertical transmission belt. This ultimately drives the dust removal fan to work, enabling simultaneous start-up of dust removal when heat dissipation begins. Dust and impurities swept off by the cleaning components can be automatically drawn into the dust removal pipe without manual intervention, preventing secondary contamination of the filter belt by dust. This saves time and effort, effectively ensuring heat dissipation performance and quality, and preventing blockages.

[0009] As a preferred embodiment of the present invention, the dust exhaust pipe is fixedly installed on the outer side wall of the bottom of the box, and the dust exhaust pipe is correspondingly arranged with the dust exhaust fan. The outer opening end of the dust exhaust pipe is tightly fitted with a cap and the cap has a ventilation hole.

[0010] This design allows the dust exhaust pipe to direct the dust and impurities extracted by the dust exhaust fan out of the housing, preventing dust from spreading inside. The cover prevents external debris from entering the housing through the dust exhaust pipe, while the ventilation holes ensure smooth airflow, balance the air pressure inside and outside the dust exhaust pipe, and ensure unimpeded dust removal efficiency. Furthermore, the cover can be opened to clean large particles inside the dust exhaust pipe when needed, making it flexible and convenient to use.

[0011] In a preferred embodiment of the present invention, a winding roller is connected inside the winding frame via bearings, a winding motor is fixedly installed on the outer rear wall of the winding frame, the output end of the winding motor is fixedly connected to the winding roller, and the two ends of the filter belt are fixed to the corresponding winding rollers by bolts. The filter belt is made of flexible plastic material.

[0012] With this setup, when the winding motor drives the winding roller to rotate, it can move the flexible plastic filter belt along the heat dissipation vent, realizing the winding of the old filter area and the replacement of the new filter area. There is no need to manually disassemble and replace the filter screen, avoiding the situation where traditional fixed dustproof nets are easy to clog and time-consuming to clean. It ensures that the heat dissipation vent has smooth ventilation for a long time and does not interrupt the heat dissipation work, saving time and effort, and thus helping to further improve the efficiency of heat dissipation.

[0013] In a preferred embodiment of the present invention, the inner top side and the inner bottom side of the heat dissipation vent are connected by a limiting rotating cylinder via bearings, the filter belt passes between the limiting rotating cylinder and the heat dissipation vent, and the filter belt and the limiting rotating cylinder are slidably connected.

[0014] This setting allows the limiting drum to guide the moving filter belt, ensuring that the filter belt always fits the filtration area of ​​the heat dissipation vent without shifting or wrinkling, thus guaranteeing complete filtration coverage.

[0015] As a preferred embodiment of the present invention, the bottom sides of the housing are provided with clearance holes for the filter belt to pass through. Two support blocks are fixedly connected to the outer wall of the housing above the clearance holes. A guide cylinder is connected between the support blocks through a bearing. The filter belt and the guide cylinder are slidably connected.

[0016] This design allows the clearance holes to provide a channel for the filter belt to pass from inside the box to the outside and connect to the winding assembly. The guide drum guides the filter belt, ensuring that the filter belt moves smoothly and stably during the winding process.

[0017] In a preferred embodiment of the present invention, the cleaning component includes positioning blocks and cleaning plates. Positioning blocks are fixedly connected to the bottom of the partition and the housing. T-shaped slots are provided on the opposite surfaces of the positioning blocks. Cleaning brushes are fixedly connected to the opposite surfaces of the cleaning plates. T-shaped inserts are fixedly connected to the other side of the cleaning plates. The inserts and slots are matched and connected. The cleaning brushes are tightly attached to both sides of the filter belt.

[0018] With this setup, when the filter belt moves under the drive of the winding assembly, the brush can simultaneously sweep away the dust and impurities attached to both sides of the filter screen, making the cleaning more thorough and preventing dust residue from clogging the filter screen pores, thus ensuring the long-term filtration efficiency of the filter screen. The cleaning plate is connected by matching inserts, positioning blocks, and slots, making it easy to slide and disassemble. When the cleaning brush needs to be replaced, the cleaning plate can be directly pulled out along the slot, which is simple to operate and reduces maintenance costs.

[0019] A method of using a rapid heat dissipation device for a high-voltage switchgear, applicable to the aforementioned rapid heat dissipation device for a high-voltage switchgear, includes the following steps: S1. Activate the heat dissipation components to form a directional airflow inside the enclosure, expelling the hot air generated by the components through the heat dissipation vents, reducing the surrounding temperature and improving the heat dissipation effect; S2. The filter tape that fits into the heat dissipation vent filters dust in the airflow to prevent contamination of the inside of the cabinet. At this time, the winding assembly does not operate. S3. When the filter belt becomes dirty and needs to be cleaned, start the winding assembly to move the filter belt and allow the clean filter belt to take its place. At the same time, the cleaning assembly sweeps away the dirty filter belt, and the dust removal assembly extracts the fallen dust. S4. After winding is complete, pause the winding assembly. The heat dissipation assembly continues to work. Repeat step three when the filter belt gets dirty again.

[0020] Compared with existing technologies, the beneficial effects of this invention are as follows: First, by using a cooling motor to drive a cooling fan to form a directional airflow, and coordinating with an active wheel to link with a dust removal component, heat dissipation and dust removal share power, simplifying the structure and enabling simultaneous operation, thus significantly improving heat dissipation efficiency; Second, by innovatively using a winding component to drive a flexible filter belt to move, replacing the traditional fixed dustproof net, frequent manual replacement is not required. Combined with the cleaning component's double-sided dust sweeping and the dust removal component's extraction, the problem of filter clogging is completely solved, ensuring continuous heat dissipation; The overall device is easy to operate and maintain, has low energy consumption, can stably dissipate heat for box-type transformers for a long time, has a wide range of applications, and effectively improves heat dissipation efficiency.

A dust removal assembly is installed on the housing 1 below the heat dissipation assembly on the left side. The dust removal assembly is located below the partition 7. Cleaning components are installed on the bottom of the partition 7 and the inner bottom of the housing 1. The sides of the housing 1... All outer walls are equipped with winding assemblies, each including a winding frame 3. A filter belt 303 is wound between two winding frames 3. The filter belt 303 is attached to the heat dissipation vent 102 and passes through the housing 1 between the cleaning assemblies. The heat dissipation assemblies are used to dissipate and ventilate the heat generated by the components. The filter belt 303 is used to filter the dust at the heat dissipation vent 102. The winding assembly is used to drive the filter belt 303 to wind and move. The cleaning assembly is used to clean the dust and impurities on the filter belt 303. The dust removal assembly is used to exhaust the impurities that fall off during sweeping.

[0026] Specifically, the heat dissipation assembly includes a heat dissipation fan 4, a support frame 701 is fixedly connected to the top of the partition 7, a heat dissipation motor 402 is fixedly installed on the top of the support frame 701, a heat dissipation shaft 401 is fixedly connected to the output end of the heat dissipation motor 402, the heat dissipation fan 4 is fixedly connected to the end of the heat dissipation shaft 401, and a drive wheel 403 is sleeved and fixed on the heat dissipation shaft 401.

[0027] Using the above solution, the cooling motor 402 drives the cooling shaft 401 to rotate the cooling fan 4, which can form a directional airflow in the housing 1, quickly guiding the heat generated by the components during operation to the heat dissipation port 102 for discharge, greatly improving the heat dissipation efficiency; the drive wheel 403 can drive the subsequent dust removal component to rotate, so that the heat dissipation component and the dust removal component share the same power source, simplifying the overall structure of the device, reducing energy consumption, and ensuring the synchronization of heat dissipation and dust removal actions; the support frame 701 provides fixed support for the cooling motor 402 and the cooling shaft 401.

[0028] Specifically, the dust removal assembly includes a dust removal fan 5 and a dust removal pipe 507. A support plate 105 is fixedly connected to the bottom of the housing 1. A dust removal shaft 501 is connected to the end side wall of the support plate 105 via a bearing. The dust removal fan 5 is fixedly connected to the end of the dust removal shaft 501. A driven wheel 502 is sleeved and fixed on the dust removal shaft 501. A support shaft 504 is connected to the left inner wall of the housing 1 via a bearing. A driven wheel 505 and a driven wheel 506 are sleeved and fixed on the support shaft 504. The driven wheel 502 and the driven wheel 505 are connected by a vertical transmission belt 503. The vertical transmission belt 503 slides through the partition 7. The driving wheel 403 and the driven wheel 506 are connected by a horizontal transmission belt 404.

[0029] Using the above solution, the active wheel 403 of the heat dissipation component drives the driven wheel 502 and the dust removal shaft 501 to rotate via the horizontal transmission belt 404, driven wheel three 506, support shaft 504, driven wheel two 505, and vertical transmission belt 503. This ultimately drives the dust removal fan 5 to work, achieving simultaneous start-up of dust removal when heat dissipation starts. Without manual intervention, the dust and impurities swept off by the cleaning components can be automatically drawn to the dust removal pipe 507, avoiding secondary contamination of the filter belt 303 by dust. This saves time and effort, effectively ensuring heat dissipation effect and quality, and preventing blockage.

[0030] Specifically, the dust exhaust pipe 507 is fixedly installed on the outer side wall of the bottom of the box 1. The dust exhaust pipe 507 is correspondingly arranged with the dust exhaust fan 5. The outer opening end of the dust exhaust pipe 507 is tightly sealed with a cover and the cover has a ventilation hole.

[0031] Using the above solution, the dust exhaust pipe 507 can direct the dust and impurities extracted by the dust exhaust fan 5 to the outside of the housing 1, preventing dust from spreading inside the housing 1; at the same time, the cover can prevent external debris from entering the housing 1 through the dust exhaust pipe 507, while the ventilation holes can ensure smooth airflow for dust exhaust, balance the air pressure inside and outside the dust exhaust pipe 507, and ensure that the dust exhaust efficiency is not obstructed. Furthermore, when necessary, the cover can be opened to clean large particles of impurities inside the dust exhaust pipe 507, making it flexible and convenient to use.

[0032] Specifically, the inside of the winding frame 3 is connected to the winding roller 301 via bearings, and the rear outer wall of the winding frame 3 is fixedly installed with a winding motor 302. The output end of the winding motor 302 is fixedly connected to the winding roller 301. The two ends of the filter belt 303 are fixed to the corresponding winding roller 301 by bolts. The filter belt 303 is made of flexible plastic material.

[0033] Using the above solution, when the winding motor 302 drives the winding roller 301 to rotate, it can drive the flexible plastic filter screen belt 303 to move along the heat dissipation opening 102, realizing the winding of the old filter area and the replacement of the new filter area. There is no need to manually disassemble and replace the filter screen, avoiding the situation where traditional fixed dustproof nets are easy to clog and time-consuming to clean. It ensures that the heat dissipation opening 102 has smooth ventilation for a long time and does not interrupt the heat dissipation work, saving time and effort, thereby helping to further improve the efficiency of heat dissipation work.

[0034] Specifically, the inner top and inner bottom sides of the heat dissipation vent 102 are connected by a limiting rotating cylinder 103 via bearings. The filter belt 303 passes between the limiting rotating cylinder 103 and the heat dissipation vent 102, and the filter belt 303 and the limiting rotating cylinder 103 are slidably connected.

[0035] Using the above solution, the limiting rotating drum 103 can guide the moving filter belt 303, ensuring that the filter belt 303 always fits the filtration area of ​​the heat dissipation port 102 without shifting or wrinkling, thus ensuring the integrity of the filtration coverage.

[0036] Specifically, both sides of the bottom of the housing 1 are provided with clearance holes 104 for the filter belt 303 to pass through. Two support blocks 801 are fixedly connected to the outer wall of the housing 1 above the clearance holes 104. A guide cylinder 8 is connected between the support blocks 801 through a bearing. The filter belt 303 and the guide cylinder 8 are slidably connected.

[0037] Using the above solution, the clearance hole 104 provides a channel for the filter belt 303 to pass from inside the box to outside the box and connect to the winding assembly. The guide drum 8 can guide the filter belt 303 to ensure that the filter moves smoothly and stably during the winding process.

[0038] Specifically, the cleaning assembly includes a positioning block 603 and a cleaning plate 6. The bottom of the partition 7 and the housing 1 are both fixedly connected to the positioning block 603. T-shaped slots 604 are provided on the opposite surfaces of the positioning block 603. Cleaning brushes 601 are fixedly connected to the opposite surfaces of the cleaning plate 6. T-shaped inserts 602 are fixedly connected to the other side of the cleaning plate 6. The inserts 602 and the slots 604 are matched and connected. The cleaning brushes 601 are tightly attached to both sides of the filter belt 303.

[0039] Using the above solution, when the filter belt 303 moves under the drive of the winding assembly, the brush can simultaneously sweep away the dust and impurities attached to both sides of the filter screen, making the cleaning more thorough and preventing dust residue from clogging the filter screen pores, thus ensuring the long-term filtration efficiency of the filter screen. The cleaning plate 6 is connected by the matching of the insert block 602, the positioning block 603 and the slot 604, which facilitates its sliding installation and removal. When the cleaning brush 601 needs to be replaced, the cleaning plate 6 can be directly pulled out along the slot 604, which is simple to operate and reduces maintenance costs.

[0040] A method of using a rapid heat dissipation device for a high-voltage switchgear, applicable to the aforementioned rapid heat dissipation device for a high-voltage switchgear, includes the following steps: S1. Activate the heat dissipation components to form a directional airflow inside the housing 1, and discharge the hot air generated by the components through the heat dissipation vent 102 to reduce the ambient temperature and improve the heat dissipation effect. S2. The filter tape 303, which is attached to the heat dissipation vent 102, filters the dust in the airflow to prevent contamination of the inside of the housing 1. At this time, the winding assembly does not operate. S3. When the filter belt 303 becomes dirty and needs to be cleaned, start the winding assembly to move the filter belt 303, allowing the clean filter belt 303 to take its place. At the same time, the cleaning assembly sweeps away the dirty filter belt 303, and the dust removal assembly extracts and removes the fallen dust. S4. After winding is complete, pause the winding assembly. The heat dissipation assembly continues to work. Repeat step three when the filter belt 303 gets dirty again.

[0041] Working principle of the invention: When in use, the heat dissipation assembly is activated: the heat dissipation motor 402 drives the heat dissipation shaft 401 to rotate, which on the one hand drives the heat dissipation fan 4 to form a directional airflow, guiding the hot air generated by the components to the heat dissipation vents 102 on both sides of the housing 1 to be discharged, thus achieving basic heat dissipation; on the other hand, the drive wheel 403 on the heat dissipation shaft 401 drives the driven wheel 506 of the supporting shaft 504 through the horizontal transmission belt 404, and then through the driven wheel 505 of the supporting shaft 504 and the vertical transmission belt 503, it links the driven wheel 502 of the dust exhaust shaft 501, so that the dust exhaust fan 5 rotates synchronously. The flexible filter belt 303 at the heat dissipation vent 102 intercepts dust in the airflow to prevent contamination of internal components. When the filter is dirty, the winding motor 302 of the winding assembly drives the winding roller 301 to rotate, which moves the filter belt 303 to fill the gap in the clean area for filtration. During the movement of the filter belt 303, the baffle 7 and the cleaning brush 601 of the bottom cleaning assembly of the box 1 adhere to both sides of the filter and sweep off the surface dust. The dust exhaust fan 5 then draws the dust out of the box through the dust exhaust pipe 507. The entire process requires no frequent manual intervention. All components work together to achieve integrated operation of heat dissipation, filtration, dust removal, and dust extraction, ensuring long-term stable and efficient heat dissipation of the device.

A method of using a rapid heat dissipation device for a high-voltage switchgear, characterized in that, The high-voltage switchgear rapid heat dissipation device according to any one of claims 1-8 comprises the following steps: S1. Start the heat dissipation components to form a directional airflow in the box (1) and discharge the hot air generated by the components through the heat dissipation vent (102) to reduce the surrounding temperature and improve the heat dissipation effect. S2. Using the filter tape (303) that is attached to the heat dissipation vent (102), the dust in the airflow is filtered to avoid contaminating the inside of the box (1). At this time, the winding assembly does not operate. S3. When the filter belt (303) is dirty and needs to be cleaned, start the winding assembly to move the filter belt (303) so that the clean filter belt (303) can fill the gap. At the same time, the cleaning assembly sweeps the dirty filter belt (303) and the dust removal assembly sucks up the fallen dust. S4. After winding is completed, pause the winding assembly and continue to work the heat dissipation assembly. When the filter belt (303) gets dirty again, repeat step three.
