Abstract
Description
Technical Field
[0001] This invention relates to the field of low-voltage switchgear technology, and more specifically, to a high-efficiency heat dissipation type low-voltage switchgear. Background Technology
[0002] Low-voltage switchgear, as an indispensable component of power systems, is widely used in power plants, petroleum, chemical, and high-rise building industries, serving as key equipment for power transmission, distribution, and energy conversion. Especially in outdoor environments, these switchgear must be able to withstand various harsh weather conditions to ensure the stable operation of the power system.
[0003] Electrical components generate a significant amount of heat during operation. If heat dissipation is insufficient, overheating can occur, affecting equipment performance and even posing safety hazards. Traditional outdoor low-voltage switchgear relies primarily on natural convection and simple ventilation holes for heat dissipation. This method is inefficient and insufficient for practical needs. Especially in outdoor environments, open or simple ventilation structures allow dust, moisture, and contaminants to enter the cabinet, accumulating over time and forming an insulating layer that hinders heat dissipation and increases maintenance difficulty. Furthermore, under high-load conditions, such as high summer temperatures or extreme weather, a single heat dissipation method is ineffective.
[0004] To improve heat dissipation efficiency, some existing outdoor low-voltage switchgear cabinets are equipped with cooling fans inside the cabinet. However, these fans are usually only installed near electronic components, providing only short-term relief from localized overheating. Hot air in other areas cannot be quickly expelled, resulting in limited overall heat dissipation. More importantly, without effective protective measures to prevent fires and other accidents caused by overheating, critical facilities operating continuously for extended periods will face significant safety hazards. Summary of the Invention

[0012] As a further aspect of the present invention: the shielding mechanism further includes a mesh fixedly connected to the top plate and the bottom sides of the adjustment plate, and the mesh is made of a flexible material. Sliders are fixedly connected to both ends of the bottom of the mesh, and limiting frames fixedly connected to the switch cabinet are provided on both sides of the mesh. The sliders are slidably connected to the inside of the limiting frames.
[0013] As a further embodiment of the present invention: the support mechanism further includes a first threaded rod and a second threaded rod rotatably connected to the upper surface of the fixed plate and flush with the fixed rod. One end of the first threaded rod is provided with a second servo motor fixedly connected to the fixed plate, and the output end of the second servo motor is fixedly connected to the first threaded rod. The outer circular surfaces of the first threaded rod and the fixed rod are jointly provided with a movable support. The interior of the movable support is respectively provided with a threaded sleeve and a sliding sleeve connected to the first threaded rod and the fixed rod, respectively. Support rods are provided on both sides of the outer surface of the movable support, and one end of the support rod is hingedly connected to the movable support, and the other end is hingedly connected to the bottom of the adjusting plate.
[0014] As a further aspect of the present invention: a transmission assembly is provided between the first threaded rod and the second threaded rod.

The cooling pipe and the cooling box are both fixedly connected to the first storage cylinder to store rainwater.
[0017] As a further aspect of the present invention: the interior of the cooling box is cylindrical, while its two sides are fan-shaped; and the corners of the cooling box are at a 70-degree angle to facilitate the movement of the fan blades.
[0018] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:
[0019] (1) This solution is equipped with a cooling mechanism and a drive mechanism. The servo motor provides the driving force, which makes the fan blades rotate inside the first and second storage cylinders to form a strong airflow. The airflow effectively removes heat from various parts of the cabinet through the synergistic effect of the cooling pipe and the cooling box, ensuring uniform heat dissipation. This not only ensures the uniform dissipation of heat inside the entire cabinet and avoids local overheating, but also improves the overall heat dissipation efficiency of the equipment. Furthermore, the uniform heat dissipation environment reduces the risk of electrical components failing due to high temperature aging, thereby extending the service life of the equipment. At the same time, the optimized heat dissipation system reduces safety hazards caused by overheating, such as short circuits or fires, and improves the operational reliability of the system.
[0020] (2) By setting up a shielding mechanism, the top plate combined with the mesh provides good sunshade and rain protection during use, reducing the damage of ultraviolet radiation and rainwater erosion to the cabinet and internal components; and the mesh, as a flexible barrier, can prevent large dust particles and debris from entering the cabinet without hindering air circulation, maintaining a good working environment; and the adjustable design of the first and second ventilation plates can be quickly deployed when needed to provide additional ventilation paths and improve heat dissipation efficiency; and can be closed when not needed to avoid unnecessary energy loss. Thus, through effective protection measures and an optimized heat dissipation system, the risk of electrical components failing due to overheating or corrosion is reduced, thereby extending the service life of the equipment.
[0021] (3) By setting up a support mechanism, a shielding mechanism and a temperature sensor, when encountering severe weather such as strong winds or heavy rain, the second servo motor is started to drive the first threaded rod to rotate, and the second threaded rod is driven to rotate synchronously through the transmission component. This causes the movable support to move downward along the first threaded rod, thereby pushing the support rod to change its angle, so that the adjustment plate fits more tightly against the top plate and enhances the protective effect. At this time, the adjustment plate can automatically adjust its angle according to the wind direction to ensure that rainwater will not seep into the cabinet from the side, providing an additional protective layer and keeping the inside of the equipment dry.

However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation
[0041] The following is a detailed description of a high-efficiency heat dissipation type low-voltage switchgear provided by the present invention, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.
[0042] like Figures 1 to 8 As shown, this embodiment of the invention provides a high-efficiency heat dissipation type low-voltage switchgear, including a switchgear 1, with a cabinet door 2 hinged to the front side of the switchgear 1; a cooling mechanism 3 is provided on the inner side of the cabinet door 2, the cooling mechanism 3 includes a first storage cylinder 31 fixedly connected to one end of the inner side of the cabinet door 2, a second storage cylinder 4 fixedly connected to the other end of the inner side of the cabinet door 2, a cooling box 33 fixedly connected to the middle of the inner side of both the first storage cylinder 31 and the second storage cylinder 4, a cooling pipe 32 fixedly connected to the outer surface of both the first storage cylinder 31 and the second storage cylinder 4, fan blades 6 are provided on both sides of the cooling box 33, and a driving mechanism 5 for driving the fan blades 6 to move is provided on both the first storage cylinder 31 and the second storage cylinder 4;
[0043] The drive mechanism 5 includes a first drive rod 52 and a second drive rod 54 rotatably connected to the middle of the first storage cylinder 31 and the second storage cylinder 4, respectively. A first servo motor 51 for driving the first drive rod 52 is fixedly connected to the middle of the top of the second storage cylinder 4. A main gear 57 is fixedly connected to the upper end of the outer circular surface of the first drive rod 52 and the second drive rod 54. A driven gear 59 is meshed with the outer circular surface of the main gear 57. A rotating rod 58 rotatably connected to the inside of the first storage cylinder 31 is provided inside the driven gear 59. The fan blade 6 is fixedly connected to the outer circular surface of the rotating rod 58.
[0044] like Figure 3 , Figure 5 , Figure 6 As shown, the internal structure and function of the first storage cylinder 31 and the second storage cylinder 4 are the same, but their positions are different. The upper ends of the outer circular surfaces of the first drive rod 52 and the second drive rod 54 are respectively fixedly connected to the first pulley 53 and the second pulley 55. The outer surfaces of the first pulley 53 and the second pulley 55 are jointly fitted with a belt 56.
[0045] To address the issue that in existing outdoor low-voltage switchgear, cooling fans are typically only installed near electronic components, resulting in limited heat dissipation in localized areas while hot air in other areas is difficult to expel quickly. Although this alleviates localized overheating to some extent, it has limited impact on overall heat dissipation efficiency and cannot effectively solve the problem of overall cabinet temperature rise, the following technical solution is adopted. This solution mainly consists of a cooling mechanism 3, a second storage cylinder 4, a drive mechanism 5, and fan blades 6. When the outdoor low-voltage switchgear is in use, a temperature sensor 10 measures the internal temperature of the switchgear 1 in real time. When the temperature exceeds a set threshold (e.g., 25 degrees Celsius), the temperature sensor 10 transmits a signal to the control system, triggering the first servo motor 51 to start. The first servo motor 51 drives the first drive rod 52 to rotate, which in turn drives the first pulley 53 to rotate synchronously. Through the belt 56, the second pulley 55 rotates accordingly, causing the second drive rod 54 to rotate synchronously within the second storage cylinder 4. The main gear 57 rotates along with the first drive rod 52 and the second drive rod 54. Through meshing with the driven gear 59, the driven gear 59 and its internal rotating rod 58 rotate together. During the rotation of the rotating rod 58, the fan blades 6 on it rotate inside the first storage cylinder 31 and the second storage cylinder 4, creating a powerful airflow. This airflow, through the synergistic effect of the cooling pipe 32 and the cooling box 33, effectively removes heat from various locations within the cabinet, ensuring uniform overall heat dissipation. In this process, the cooling mechanism 3 and the drive mechanism 5 not only ensure uniform heat dissipation throughout the cabinet, avoiding localized overheating and improving the overall heat dissipation efficiency, but also, through the use of the intelligently controlled first servo motor 51, allow it to automatically adjust its operating state according to actual temperature changes, ensuring both effective heat dissipation and energy savings. Furthermore, the uniform heat dissipation environment reduces the risk of electrical components failing due to high-temperature aging, thus extending the equipment's lifespan. Simultaneously, the optimized heat dissipation system reduces safety hazards caused by overheating, such as short circuits or fires, improving the system's operational reliability.
[0046] like Figure 1 , Figure 3 , Figure 7 As shown, a fixed plate 7 is fixedly connected to the inner top of the switch cabinet 1. A temperature sensor 10 is installed on one side of the upper surface of the fixed plate 7. A shielding mechanism 9 for blocking sunlight and rain is provided on the top of the switch cabinet 1. A support mechanism 8 for supporting the shielding mechanism 9 is provided on the upper surface of the fixed plate 7. The support mechanism 8 includes fixed rods 83 fixedly connected to both sides of the upper surface of the fixed plate 7. The shielding mechanism 9 includes a top plate 91 set on the top of the switch cabinet 1 and fixedly connected to the fixed rods 83.
[0047] like Figure 2 , Figure 3 , Figure 4As shown, limit rods 92 are fixedly connected to both sides of the outer surface of the top plate 91. Adjustment plates 93 are hinged to the limit rods 92 on both sides of the top plate 91. First vent plates 94 are hinged to both sides of the top of the switch cabinet 1. A second vent plate 95 is hinged to the middle of the adjustment plate 93 and the first vent plate 94. The first vent plate 94 and the second vent plate 95 are folded together.
[0048] like Figure 2 , Figure 3 , Figure 4 As shown, the shielding mechanism 9 also includes a mesh 96 fixedly connected to the top plate 91 and the bottom sides of the adjustment plate 93. The mesh 96 is made of a flexible material. Slider 97 is fixedly connected to both ends of the bottom of the mesh 96. Limiting frames 98 fixedly connected to the switch cabinet 1 are provided on both sides of the mesh 96. The slider 97 is slidably connected to the inside of the limiting frame 98.
[0049] In normal weather conditions, the shielding mechanism 9 positions the top plate 91 above the switch cabinet 1, effectively blocking sunlight and rain. The mesh 96 hangs naturally and is stabilized within the limit frame 98 by the slider 97, preventing dust and debris from entering the cabinet. During severe weather such as strong winds or heavy rain, the top plate 91 and the mesh 96 effectively block wind and rain intrusion. At this time, the adjusting plate 93 automatically adjusts its angle according to the wind direction, ensuring that rainwater does not seep into the cabinet from the sides. During high-temperature seasons or when the equipment operates under heavy load, the temperature sensor 10 detects that the internal temperature has risen to a preset value (e.g., 25 degrees Celsius). The system transmits a signal to the control system, triggering the cooling mechanism 3. Simultaneously, the supporting mechanism 8 moves the adjusting plate 93 upwards. At the same time, the hinged first and second ventilator plates 94 and 95 are extended by traction, forming larger ventilation openings, increasing airflow, and aiding in heat dissipation. The linkage between the adjustable plate 93 and the ventilated plate allows for flexible adjustment of the ventilation area according to actual needs, minimizing the impact of external adverse factors on the cabinet interior while ensuring sufficient heat dissipation. Therefore, during the aforementioned operation, the top plate 91, combined with the mesh 96, provides excellent sun and rain protection, reducing damage to the cabinet and internal components from ultraviolet radiation and rainwater erosion. Furthermore, the mesh 96, acting as a flexible barrier, prevents large dust particles and debris from entering the cabinet without hindering airflow, maintaining a good working environment. The adjustable design of the first and second ventilated plates 94 and 95 allows for rapid deployment when needed, providing additional ventilation paths and improving heat dissipation efficiency; conversely, they can be closed when not needed, avoiding unnecessary energy loss. Through effective protective measures and an optimized heat dissipation system, the risk of electrical components failing due to overheating or corrosion is reduced, thereby extending the equipment's lifespan.
[0050] like Figure 3 , Figure 7As shown, the support mechanism 8 also includes a first threaded rod 82 and a second threaded rod 86 rotatably connected to the upper surface of the fixed plate 7 and flush with the fixed rod 83. One end of the first threaded rod 82 is provided with a second servo motor 81 fixedly connected to the fixed plate 7, and the output end of the second servo motor 81 is fixedly connected to the first threaded rod 82. The outer circular surfaces of the first threaded rod 82 and the fixed rod 83 are jointly provided with a movable support 84. The interior of the movable support 84 is respectively provided with a threaded sleeve and a sliding sleeve connected to the first threaded rod 82 and the fixed rod 83. Support rods 85 are provided on both sides of the outer surface of the movable support 84, and one end of the support rod 85 is hingedly connected to the movable support 84, and the other end is hingedly connected to the bottom of the adjusting plate 93.
[0051] like Figure 7 As shown, a transmission assembly 87 is provided between the first threaded rod 82 and the second threaded rod 86. The transmission assembly 87 includes a first fixed wheel fixedly connected to the outer surface of the first threaded rod 82, and a second fixed wheel fixedly connected to the outer surface of the second threaded rod 86. A transmission belt is sleeved on the outer surfaces of the first fixed wheel and the second fixed wheel.
[0052] Under normal weather conditions, the top plate 91 is located above the top of the switch cabinet 1, serving to shield it from sunlight and rain. The mesh 96 hangs naturally and is kept stable within the limit frame 98 by the slider 97, preventing external dust and debris from entering the cabinet. The movable support 84 in the support mechanism 8 is in its initial position, and the support rod 85 remains stationary, ensuring the stability of the top plate 91 and the adjusting plate 93. In severe weather conditions such as strong winds or heavy rain, the second servo motor 81 is activated, driving the first threaded rod 82 to rotate. This, in turn, drives the second threaded rod 86 to rotate synchronously via the transmission assembly 87. This causes the movable support 84 to move downwards along the first threaded rod 82, thereby pushing the support rod 85 to change its angle. This allows the adjusting plate 93 to fit more tightly against the top plate 91, enhancing the protective effect. At this time, the adjusting plate 93 can automatically adjust its angle according to the wind direction, ensuring that rainwater does not seep into the cabinet from the side, providing an additional protective layer and keeping the inside of the equipment dry.
[0053] During periods of high temperatures or when the equipment is under heavy load, the temperature sensor 10 detects that the internal temperature has risen to a preset value (e.g., 25 degrees Celsius). The system transmits a signal to the control system, triggering the cooling mechanism 3 to start. Simultaneously, the second servo motor 81 adjusts the position of the movable support 84, moving it upwards. The support rod 85 then causes the adjusting plate 93 to flip upwards, causing the first and second ventilator plates 94 and 95 to expand outwards, achieving optimal ventilation and minimizing the impact of external adverse factors on the cabinet's interior while ensuring sufficient heat dissipation. When the temperature drops to a safe range or after severe weather, the first and second ventilator plates 94 and 95 automatically reset to their folded state, closing the vents and continuing to provide dust and rain protection. Simultaneously, the second servo motor 81 rotates in the opposite direction, moving the movable support 84 back to its initial position, restoring the support rod 85 to its original state, and returning the adjusting plate 93 to its initial position, ensuring the entire shielding mechanism 9 returns to normal operation.
[0054] like Figure 2 , Figure 7 , Figure 8 As shown, a water collection trough 11 is fixedly connected to the upper surface of the regulating plate 93. The cooling mechanism 3 also includes a water collection bucket 34 fixedly connected to both sides of the inner wall of the switch cabinet 1. A second connecting pipe 36 is fixedly connected to the top of the water collection bucket 34, and one end of the second connecting pipe 36 passes through the regulating plate 93 and connects to the water collection trough 11 so that rainwater can enter the water collection bucket 34.
[0055] like Figure 2 , Figure 7 , Figure 8 As shown, a first connecting pipe 35 is provided at the bottom of the water collection tank 34. One end of the first connecting pipe 35 is fixedly connected to the first storage cylinder 31, and the other end is fixedly connected to the water collection tank 34. The cooling pipe 32 and the cooling box 33 are both fixedly connected to the first storage cylinder 31 to store rainwater.
[0056] like Figure 8 As shown, the interior of the cooling box 33 is cylindrical, while its two sides are fan-shaped; and the corners of the cooling box 33 are at a 70-degree angle to facilitate the movement of the fan blades 6.
[0057] In the event of severe weather such as strong winds or heavy rain, the top plate 91 and its mesh 96 effectively block wind and rain from entering. At this time, the adjusting plate 93 automatically adjusts its angle according to the wind direction, ensuring that rainwater does not seep into the cabinet from the sides, providing an additional protective layer and maintaining the dryness of the equipment's interior. Simultaneously, rainwater is guided to the water collection trough 11 on the adjusting plate 93 and flows into the water collection tank 34 through the second connecting pipe 36. This not only prevents rainwater from directly entering the cabinet but also effectively collects rainwater. The collected rainwater is then transferred to the first storage cylinder 31 through the first connecting pipe 35 and further flows into the cooling pipe 32 and cooling box 33 for storage. This rainwater stored in the cooling system can be used as a cooling medium when needed, improving cooling efficiency and reducing dependence on external water sources. Furthermore, by using the cooling pipe 32 and the cooling box 33 in conjunction with the rotating fan blade 6, the cooling box 33 is centered on a cylindrical shape with 70-degree bends on both sides. This not only optimizes the airflow path, but also enables the fan blade 6 to drive the airflow more effectively when it rotates, thus promoting heat dissipation.
[0058] In use, this invention first utilizes a temperature sensor 10 to measure the internal temperature of the switch cabinet 1 in real time. When the temperature exceeds a set threshold (e.g., 25 degrees Celsius), the temperature sensor 10 transmits a signal to the control system, triggering the first servo motor 51 to start. The first servo motor 51 drives the first drive rod 52 to rotate, which in turn drives the first pulley 53 to rotate synchronously. Through the belt 56, the second pulley 55 rotates accordingly, causing the second drive rod 54 to rotate synchronously inside the second storage cylinder 4. The main gear 57 rotates along with the rotation of the first drive rod 52 and the second drive rod 54. Through meshing with the driven gear 59, the driven gear 59 and its internal rotating rod 58 rotate together, driving the fan blades 6 on it to rotate inside the first storage cylinder 31 and the second storage cylinder 4, forming a powerful airflow. The airflow, through the synergistic effect of the cooling pipe 32 and the cooling box 33, effectively removes heat from various locations inside the cabinet, ensuring uniform overall heat dissipation. In the event of severe weather such as strong winds or heavy rain, the second servo motor 81 is activated, driving the first threaded rod 82 to rotate. This, in turn, drives the second threaded rod 86 to rotate synchronously via the transmission assembly 87. This causes the movable support 84 to move downwards along the first threaded rod 82, thereby pushing the support rod 85 to change its angle. This allows the adjusting plate 93 to fit more tightly against the top plate 91, enhancing the protective effect. At this time, the adjusting plate 93 can automatically adjust its angle according to the wind direction, ensuring that rainwater does not seep into the cabinet from the side, providing an additional protective layer and keeping the inside of the equipment dry. Rainwater is guided to the water collection trough 11 on the adjusting plate 93 and flows into the water collection tank 34 through the second connecting pipe 36. The collected rainwater is then transferred to the first storage cylinder 31 through the first connecting pipe 35 and further flows into the cooling pipe 32 and cooling box 33 for storage. This allows the fan blades 6 to work in conjunction with the cooling pipes, more effectively driving airflow and promoting heat dissipation. Furthermore, during high-temperature seasons or high-load operation, when the temperature sensor 10 detects that the internal temperature has risen to a preset value (e.g., 25 degrees Celsius), the system transmits a signal to the control system, triggering the cooling mechanism 3 to start. Simultaneously, the second servo motor 81 adjusts the position of the movable support 84, causing it to move upwards. The support rod 85 then causes the adjusting plate 93 to flip upwards, thereby causing the first ventilator 94 and the second ventilator 95 to expand outwards, achieving optimal ventilation and minimizing the impact of external adverse factors on the cabinet's interior while ensuring sufficient heat dissipation. When the temperature drops to a safe range or after severe weather, the first ventilator 94 and the second ventilator 95 automatically reset to their folded state, closing the vents and continuing to provide dust and rain protection. Simultaneously, the second servo motor 81 rotates in the opposite direction, moving the movable support 84 back to its initial position, restoring the support rod 85 to its original state, and returning the adjusting plate 93 to its initial position, ensuring the entire shielding mechanism 9 returns to normal operation.
