Description

Technical Field

[0001] The present invention relates to the technical field of low-voltage switchgear, and more specifically, to an efficient heat dissipation type low-voltage switchgear. Background Art

[0002] As an indispensable part of the power system, low-voltage switchgear is widely used in industries such as power plants, oil, chemical industry, and high-rise buildings, and is a key device for power transmission, distribution, and power conversion. Especially in outdoor environments, these switchgears must be able to cope with various harsh weather conditions to ensure the stable operation of the power system.

[0003] During the operation of electrical components, a large amount of heat will be generated. If the heat dissipation is not timely, it will cause the equipment temperature to be too high, affecting its normal performance and even posing a safety hazard. Traditional outdoor low-voltage switchgear mainly relies on natural convection and simple ventilation holes for heat dissipation. This method has low heat dissipation efficiency and is difficult to meet the actual needs. Especially in outdoor environments, open or simple ventilation structures are likely to allow dust, moisture, and pollutants to enter the cabinet. Long-term accumulation will form an insulating layer, hinder heat dissipation, and increase the maintenance difficulty. In addition, under high-intensity loads, such as in high temperatures in summer or extreme climate conditions, the single heat dissipation method has poor effects.

[0004] In order to improve the heat dissipation efficiency, some existing outdoor low-voltage switchgears will install cooling fans inside the cabinet. However, these fans are usually only installed near the electronic components, which can only relieve the local overheating problem for a short time, and the hot air in other positions is difficult to be quickly discharged, so the overall heat dissipation effect is limited. More importantly, if there is no effective protection measure to prevent accidents such as fires caused by overheating, the key facilities operating continuously for a long time will face significant safety hazards.

[0017] Compared with the prior art, the above technical solutions provided by the present invention have at least the following beneficial effects: (1) In this solution, by setting up a cooling mechanism and a driving mechanism, and using the servo motor to provide driving force, the fan blades rotate inside the first storage cylinder and the second storage cylinder, forming a strong air flow. Through the synergistic effect of the cooling pipe and the cooling box, the air flow effectively takes away the heat at each position inside the cabinet, ensuring uniform overall heat dissipation. It can not only ensure the uniform dissipation of heat inside the entire cabinet, avoid local overheating problems, and improve the overall heat dissipation efficiency of the equipment; but also 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.

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.

[0019] (3) By providing a support mechanism, an occlusion mechanism, and a temperature sensor, when encountering bad weather such as strong wind or heavy rain, by starting the second servo motor, driving the first threaded rod to rotate, and driving the second threaded rod to rotate synchronously through the transmission component, this causes the movable support to move downward along the first threaded rod, and then pushes the support rod to change the angle, making the adjustment plate fit more closely to the top plate, enhancing the protection effect; at this time, the adjustment plate can automatically adjust the angle according to the wind direction to ensure that rainwater does not seep into the cabinet body from the side, providing an additional protective layer and maintaining the dryness inside the equipment.

[0023] As shown in the figure, in order to clearly implement the structure of the embodiments of the present invention, specific structures and devices are marked in the figure. However, this is only for schematic needs and is not intended to limit the present invention to this specific structure, device, and environment. Those of ordinary skill in the art can adjust or modify these devices and environments according to specific needs. Detailed implementation manners

[0024] The following describes in detail a highly efficient heat dissipation type low-voltage switchgear provided by the present invention in combination with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present invention.

[0025] As Figures 1 to 8 shown, an embodiment of the present invention provides a highly efficient heat dissipation type low-voltage switchgear, including a switchgear 1, and a cabinet door 2 is hinged to the front side of the switchgear 1; a cooling mechanism 3 is arranged inside the cabinet door 2. The cooling mechanism 3 includes a first storage cylinder 31 fixedly connected to one end inside the cabinet door 2, a second storage cylinder 4 is fixedly connected to the other end inside the cabinet door 2, cooling boxes 33 are fixedly communicated with the middle parts inside both the first storage cylinder 31 and the second storage cylinder 4, cooling pipes 32 are fixedly communicated around the outer surfaces of both the first storage cylinder 31 and the second storage cylinder 4, fan blades 6 are arranged on both sides of the cooling box 33, and a driving mechanism 5 for driving the fan blades 6 to move is jointly arranged on the first storage cylinder 31 and the second storage cylinder 4; Among them, the driving mechanism 5 includes a first driving rod 52 and a second driving rod 54 respectively rotatably connected to the middle inside of the first storage cylinder 31 and the second storage cylinder 4. And a first servo motor 51 for driving the movement of the first driving rod 52 is fixedly connected to the middle of the top of the second storage cylinder 4. Main gears 57 are fixedly connected to the upper ends of the outer circumferential surfaces of the first driving rod 52 and the second driving rod 54. Driven gears 59 are meshed with the outer circumferential surfaces of the main gears 57. And a rotating rod 58 rotatably connected to the inside of the first storage cylinder 31 is arranged inside the driven gear 59. The fan blades 6 are fixedly connected around the outer circumferential surface of the rotating rod 58.

[0026] As Figure 3 、 Figure 5 、 Figure 6 shown, the internal structures and functions of the first storage cylinder 31 and the second storage cylinder 4 are the same, but their positions are different. First belt pulleys 53 and second belt pulleys 55 are respectively fixedly connected to the upper ends of the outer circumferential surfaces of the first driving rod 52 and the second driving rod 54. A belt 56 is sleeved on the outer surfaces of the first belt pulley 53 and the second belt pulley 55.

[0027] To solve the problem in existing outdoor low-voltage switchgear cabinets, the cooling fans are usually installed only near the electronic components, resulting in the cooling effect being limited to a local area, and it is difficult for the hot air in other positions to be quickly discharged. Although it can alleviate the local overheating problem to a certain extent, the improvement of the overall cooling efficiency is limited, and the temperature rise problem of the entire cabinet cannot be effectively solved. Now, the above problem is solved by adopting the above technical solution. The above technical solution mainly consists of a cooling mechanism 3, a second storage cylinder 4, a driving mechanism 5, and a fan blade 6. When the outdoor low-voltage switchgear cabinet is in use, the temperature sensor 10 is used to measure the internal temperature of the switchgear cabinet 1 in real time. When the temperature exceeds the set threshold (for example, 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 driving rod 52 to rotate, and then drives the first pulley 53 to rotate synchronously. Through the transmission of the belt 56, the second pulley 55 rotates accordingly, causing the second driving rod 54 to rotate synchronously inside the second storage cylinder 4. The main gear 57 rotates as the first driving rod 52 and the second driving rod 54 rotate. Through the meshing connection with the driven gear 59, the driven gear 59 and the rotating rod 58 inside it rotate together. During the rotation of the rotating rod 58, the fan blade 6 on it is driven to rotate inside the first storage cylinder 31 and the second storage cylinder 4, forming a strong air flow. Through the synergistic effect of the cooling pipe 32 and the cooling box 33, the air flow effectively takes away the heat from various positions inside the cabinet, ensuring uniform overall heat dissipation. During the above operation process, through the cooling mechanism 3 and the driving mechanism 5, not only can the uniform dissipation of heat inside the entire cabinet be ensured, avoiding local overheating problems and improving the overall cooling efficiency of the equipment, but also by adopting the intelligent control first servo motor 51, it can automatically adjust its working state according to the actual temperature change, ensuring both the cooling effect and saving energy consumption. And the uniform cooling 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 cooling system reduces safety hazards caused by overheating, such as short circuits or fires, improving the operating reliability of the system.

[0028] As Figure 1 , Figure 3 , Figure 7 shown, a fixing plate 7 is fixedly connected to the inner top of the switchgear cabinet 1. A temperature sensor 10 is installed on one side of the upper surface of the fixing plate 7. A shielding mechanism 9 for shielding sunlight and rain is provided on the top of the switchgear cabinet 1, and a supporting mechanism 8 for supporting the shielding mechanism 9 is provided on the upper surface of the fixing plate 7. The supporting mechanism 8 includes fixing rods 83 fixedly connected to both sides of the upper surface of the fixing plate 7. The shielding mechanism 9 includes a top plate 91 provided on the top of the switchgear cabinet 1 and fixedly connected to the fixing rods 83.

[0029] As Figure 2 , Figure 3 , Figure 4As shown in the figure, limiting rods 92 are fixedly connected to both sides of the outer surface of the top plate 91. Adjusting plates 93 hinged to the limiting rods 92 are arranged on both sides of the top plate 91. First ventilation plates 94 are hinged to both sides of the top of the switch cabinet 1. A second ventilation plate 95 is jointly hinged between the adjusting plate 93 and the first ventilation plate 94. The first ventilation plate 94 and the second ventilation plate 95 are in a folded state.

[0030] As Figure 2 、 Figure 3 、 Figure 4 As shown in the figure, the shielding mechanism 9 further includes mesh screens 96 fixedly connected to both sides of the bottom of the top plate 91 and the adjusting plates 93. The material of the mesh screens 96 is a flexible material. Both ends of the bottom of the mesh screens 96 are fixedly connected with sliders 97. Limiting frames 98 fixedly connected to the switch cabinet 1 are arranged on both sides of the mesh screens 96. The sliders 97 are slidably connected to the inside of the limiting frames 98.

[0031] Among them, when the configured shielding mechanism 9 is under normal weather conditions, the top plate 91 is located above the top of the switch cabinet 1, playing a role in shielding sunlight and rainwater. The mesh screens 96 are in a natural hanging state, and are kept stable through the sliders 97 in the limiting frames 98 to prevent external dust and sundries from entering the cabinet body. When encountering severe weather such as strong wind or heavy rain, the top plate 91 and the mesh screens 96 thereon can effectively block the intrusion of wind and rain. At this time, the adjusting plate 93 can automatically adjust the angle according to the wind direction to ensure that rainwater does not seep into the cabinet body from the side. In the high-temperature season or when the operating load of the equipment is relatively large, the temperature sensor 10 detects that the internal temperature rises to a preset value (such as 25 degrees Celsius). The system transmits the signal to the control system, triggering the cooling mechanism 3 to start. At the same time, using the support mechanism 8, the adjusting plate 93 moves upward. Meanwhile, the hinged first ventilation plate 94 and second ventilation plate 95 are unfolded due to the traction force, forming a larger ventilation opening to increase the air circulation volume and help with heat dissipation. The linkage between the adjusting plate 93 and the ventilation plates allows for flexible adjustment of the ventilation area according to actual needs, minimizing the impact of external adverse factors on the inside of the cabinet while ensuring sufficient heat dissipation. Therefore, during the above operation process, the top plate 91 combined with the mesh screens 96 provides a good function of shading and rain protection, reducing the damage to the cabinet body and internal components caused by ultraviolet radiation and rain erosion. And the mesh screens 96, as a flexible barrier, can not only prevent large-particle dust and sundries from entering the cabinet body, but also does not hinder air circulation, maintaining a good working environment. The adjustable design of the first ventilation plate 94 and the second ventilation plate 95 can be quickly unfolded when needed to provide an additional ventilation path, improving the heat dissipation efficiency; while closing when not needed to avoid unnecessary energy loss. 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.

[0032] As Figure 3 、 Figure 7As shown, the support mechanism 8 further includes a first threaded rod 82 and a second threaded rod 86 that are rotatably connected to the upper surface of the fixed plate 7 and are 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. A movable support 84 is jointly arranged on the outer circumferential surfaces of the first threaded rod 82 and the fixed rod 83. Inside the movable support 84, there are respectively arranged a threaded sleeve and a sliding sleeve connected to the first threaded rod 82 and the fixed rod 83. On both sides of the outer surface of the movable support 84, there are support rods 85, and one end of the support rod 85 is hinged to the movable support 84, and the other end is hinged to the bottom of the adjusting plate 93.

[0033] As Figure 7 shown, a transmission component 87 is jointly arranged between the first threaded rod 82 and the second threaded rod 86. The transmission component 87 includes a first fixed wheel fixedly connected to the outer circumferential surface of the first threaded rod 82. A second fixed wheel is fixedly connected to the outer circumferential surface of the second threaded rod 86. A transmission belt is jointly sleeved on the outer surfaces of the first fixed wheel and the second fixed wheel.

[0034] Under normal weather conditions, the top plate 91 is located above the top of the switch cabinet 1, playing a role in blocking sunlight and rain. The mesh screen 96 is in a natural hanging state and remains stable through the slider 97 in the limit frame 98, preventing external dust and debris from entering the cabinet body. And the movable support 84 in the support mechanism 8 is located at the initial position, and the support rod 85 remains stationary, ensuring the stability of the top plate 91 and the adjusting plate 93. When encountering bad weather such as strong wind or heavy rain, by starting the second servo motor 81, the first threaded rod 82 is driven to rotate, and the second threaded rod 86 is driven to rotate synchronously through the transmission component 87. This causes the movable support 84 to move downward along the first threaded rod 82, and then pushes the support rod 85 to change the angle, making the adjusting plate 93 fit more closely to the top plate 91 and enhancing the protection effect. At this time, the adjusting plate 93 can automatically adjust the angle according to the wind direction to ensure that rainwater does not seep into the cabinet body from the side, providing an additional protective layer and maintaining the dryness inside the equipment.

[0035] In the high-temperature season or when the operating load of the equipment is relatively large, the temperature sensor 10 detects that the internal temperature rises to a preset value (such as 25 degrees Celsius). The system transmits the signal to the control system, triggering the cooling mechanism 3 to start. At the same time, the position of the movable support 84 is adjusted by the second servo motor 81 to move it upward, and the support rod 85 is used to make the adjusting plate 93 flip upward, so that the adjusting plate 93 drives the first ventilation plate 94 and the second ventilation plate 95 to expand outward to achieve the best ventilation effect, minimizing the impact of external adverse factors on the inside of the cabinet while ensuring sufficient heat dissipation. When the temperature drops to the safe range or after bad weather, the first ventilation plate 94 and the second ventilation plate 95 automatically reset to the folded state, closing the ventilation opening and continuing to play the functions of dust-proof and rain-proof. At the same time, the second servo motor 81 rotates in the reverse direction to move the movable support 84 back to the initial position, the support rod 85 returns to its original state, and the adjusting plate 93 also returns to the initial position to ensure that the entire shielding mechanism 9 returns to the normal working state.

[0036] As Figure 2 、 Figure 7 、 Figure 8 shown, a water accumulation tank 11 is fixedly connected to the upper surface of the adjusting plate 93. The cooling mechanism 3 further includes water accumulation barrels 34 fixedly connected to both sides of the inner wall of the switch cabinet 1. The top of the water accumulation barrel 34 is fixedly communicated with a second connecting pipe 36, and one end of the second connecting pipe 36 penetrates through the adjusting plate 93 and is communicated with the water accumulation tank 11 to facilitate rainwater to enter the water accumulation barrel 34.

[0037] As Figure 2 、 Figure 7 、 Figure 8 shown, a first connecting pipe 35 is arranged at the bottom of the water accumulation barrel 34. One end of the first connecting pipe 35 is fixedly communicated with the first storage cylinder 31, and the other end is fixedly communicated with the water accumulation barrel 34. The cooling pipe 32 and the cooling box 33 are both fixedly communicated with the first storage cylinder 31 to store rainwater.

[0038] As Figure 8 shown, the inside of the cooling box 33 is cylindrical, and its two sides are fan-shaped; and the corners of the cooling box 33 form a 70-degree angle to facilitate the movement of the fan blades 6.

[0039] When encountering bad weather such as strong winds or heavy rains, the top plate 91 and the mesh 96 thereon can effectively block the intrusion of wind and rain. At this time, the adjusting plate 93 can automatically adjust the angle according to the wind direction to ensure that rainwater does not seep into the cabinet from the side, providing an additional protective layer and maintaining the dryness inside the equipment. At the same time, the rainwater is guided to the water collecting trough 11 on the adjusting plate 93 and flows into the water collecting bucket 34 through the second connecting pipe 36. This not only prevents the rainwater from directly entering the cabinet, but also effectively collects the rainwater resources. The collected rainwater is transmitted to the first storage cylinder 31 through the first connecting pipe 35 and further flows into the cooling pipe 32 and the cooling box 33 for storage. The rainwater stored in the cooling system can be used as a cooling medium when needed, improving the cooling efficiency and reducing the dependence on external water sources. And when the cooling pipe 32 and the cooling box 33 are used in conjunction with the rotating fan blade 6, since the cooling box 33 is centered on a cylindrical shape and has corners with a 70-degree angle on both sides, this not only optimizes the air flow path, but also enables the fan blade 6 to drive the air flow more effectively when rotating, promoting heat dissipation.

[0040] When the present invention is in use, first, the temperature sensor 10 is used to measure the internal temperature of the switch cabinet 1 in real time. When the temperature exceeds the set threshold (for example, 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, thereby driving the first pulley 53 to rotate synchronously, and through the transmission of 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 with the rotation of the first drive rod 52 and the second drive rod 54. Through the meshing connection with the driven gear 59, the driven gear 59 and the rotating rod 58 inside it rotate together, driving the fan blade 6 on it to rotate inside the first storage cylinder 31 and the second storage cylinder 4, forming a strong air flow. Through the synergistic effect of the cooling pipe 32 and the cooling box 33, the air flow effectively takes away the heat at various positions inside the cabinet, ensuring uniform overall heat dissipation. In the face of harsh weather such as strong winds or heavy rains, by starting the second servo motor 81, the first threaded rod 82 is driven to rotate, and through the transmission assembly 87, the second threaded rod 86 is driven to rotate synchronously. This causes the movable support 84 to move downward along the first threaded rod 82, and then pushes the support rod 85 to change the angle, making the adjusting plate 93 fit more closely to the top plate 91, enhancing the protection effect. At this time, the adjusting plate 93 can automatically adjust the angle according to the wind direction to ensure that rainwater does not seep into the cabinet from the side, providing an additional protective layer to keep the inside of the equipment dry. The rainwater is guided to the water accumulation groove 11 on the adjusting plate 93 and flows into the water accumulation bucket 34 through the second connecting pipe 36. The collected rainwater is transmitted to the first storage cylinder 31 through the first connecting pipe 35 and further flows into the cooling pipe 32 and the cooling box 33 for storage, so that when the fan blade 6 rotates, it can cooperate with them to more effectively drive the air flow and promote heat dissipation. And in the high-temperature season or under high-load operation, when the temperature sensor 10 detects that the internal temperature rises to the preset value (for example, 25 degrees Celsius), the system transmits a signal to the control system, triggering the cooling mechanism 3 to start. At the same time, the position of the movable support 84 is adjusted through the second servo motor 81 to move it upward, and the adjusting plate 93 is flipped upward by using the support rod 85, so that the adjusting plate 93 drives the first ventilation plate 94 and the second ventilation plate 95 to expand outward to achieve the best ventilation effect, minimizing the impact of external adverse factors on the inside of the cabinet while ensuring sufficient heat dissipation. When the temperature drops to the safe range or after the harsh weather, the first ventilation plate 94 and the second ventilation plate 95 automatically reset to the folded state, closing the ventilation opening and continuing to perform the functions of dust prevention and rain prevention. At the same time, the second servo motor 81 rotates in the reverse direction, moving the movable support 84 back to the initial position, the support rod 85 returns to its original state, and the adjusting plate 93 also returns to the initial position, ensuring that the entire shielding mechanism 9 returns to the normal working state.
