Description

Technical Field

[0001] This invention relates to the field of power distribution equipment technology, specifically to a heat-dissipating power distribution control device. Background Technology

[0002] Power distribution control equipment is a commonly used device in various fields. Due to its widespread use, power distribution control equipment needs to be cooled during use.

[0003] For example, a power distribution control device with easy heat dissipation, disclosed in CN117526130B, includes a power distribution box. Multiple rows of support frames are arranged vertically at intervals inside the power distribution box, and power distribution modules are arranged on the support frames. The power distribution box is provided with a first heat dissipation mechanism for dissipating heat from the power distribution modules and a second heat dissipation mechanism for dissipating heat from the power distribution box. By adopting the above technical solution, heat dissipation and ventilation of the air inside the power distribution box can be achieved, thereby improving heat dissipation efficiency.

[0004] However, inside power distribution control equipment, due to differences in the size and specifications of various electrical components, some components may protrude. Existing methods of cooling power distribution control cabinets using fans typically employ an air inlet at the bottom and an air outlet at the top, with the fan installed at the top or upper middle of the sides of the cabinet to create a natural airflow circulation from bottom to top. However, the protruding electrical components obstruct airflow in this area, leading to localized overheating. For example, when ventilating from bottom to top, the bottom of the protruding electrical component creates an obstruction, causing heat to accumulate on the bottom surface of the component, which reduces the heat dissipation effect of the component. Furthermore, a humid environment can lead to decreased insulation performance, condensation, accelerated corrosion of metal components, and may cause partial discharge and electrochemical corrosion. Therefore, it is necessary to maintain a dry environment inside the power distribution cabinet. Summary of the Invention

[0005] The purpose of this invention is to provide a heat-dissipating power distribution control device to solve the problem that obstruction of electrical components causes airflow to be blocked, resulting in localized overheating, which causes heat to accumulate on the bottom surface of the electrical components and reduces the heat dissipation effect of the electrical components.

[0013] Preferably, a push plate is fixedly connected to the output end of the linear guide rail, a mounting plate is fixedly connected to the side of the push plate away from the vertical plate, an inner shaft is rotatably connected to the outer side of the mounting plate, and a gear is fixedly connected to the middle of the outer side of the inner shaft.

[0014] Preferably, an installation cylinder is fixedly connected between the two inner shafts, and the inside of the installation cylinder is symmetrically filled with desiccant. Vertical racks are symmetrically fixedly installed on both sides of the inner wall of the cabinet, and the two gear parts are respectively meshed with the vertical racks on both sides.

[0015] Preferably, the exhaust box is provided with an exhaust assembly, which includes an air inlet on one side of the base frame. A drive motor is symmetrically fixedly installed on the inner wall of the air inlet, and a fan blade is fixedly connected to the output end of the drive motor.

[0016] Preferably, the bottom of the cabinet has a lower groove, the inside of the top plate has an upper groove, the air inlet is connected to the lower groove, the bottom of the exhaust box has an air outlet, and the upper groove is connected to the air outlet.

[0017] Preferably, filters are fixedly installed inside the air inlet and the upper slot, and adsorption plates are also fixedly installed in parallel inside the exhaust box, with no fewer than three adsorption plates. An exhaust pipe is fixedly installed on one side of the outer back of the exhaust box.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting the guide assembly, as the push plate rises and falls, the guide plate can be pushed outward in a stepped manner to guide the vertically upward airflow. Furthermore, the tilt angle of the guide plate can be adjusted to accommodate the protruding position of the electrical component body. This reduces the situation where heat accumulates at the obstruction points of the electrical component body when uniformly distributing air through the existing air guide plate. The stepped protrusion of the guide plate ensures that when air is guided at a certain point, other positions will not obstruct ventilation, thus guaranteeing ventilation and heat dissipation efficiency. Simultaneously, during air guidance, it is also convenient to blow the air towards the vertical side of the electrical component body, increasing the contact area and time between the airflow and the electrical component body, thereby improving the heat dissipation effect. The specific details are as follows:

[0019] 1. By setting up a guide assembly, during ventilation and heat dissipation, the operator activates the internal linear guide rail via the external control panel. The linear guide rail drives the push plate to move up and down. When the push plate rises, it presses against the bottom slope of one side of the trapezoidal block, causing the trapezoidal block to slide on the limit rod and stretch spring one. The trapezoidal block drives the moving plate via the lead screw, and the moving plate drives the pressing rod to move, so that the two pressing rods press against the upper and lower inclined blocks respectively. The two inclined blocks move closer to each other, and the inclined blocks drive the sliding block to slide on the side rod. The sliding block compresses spring two. The movement of the sliding block also drives the side block to move, and the two side blocks also move closer to each other. The side blocks drive the connecting block and the guide plate to move, and the guide plate drives the center block to rotate around the auxiliary shaft, so that the side of the upper and lower guide plates that are close to each other tilts outward and pushes out. When the push plate separates from the trapezoidal block, the elastic force of spring one drives the trapezoidal block to reset, and spring two drives the sliding block to reset, so that the guide plate no longer pushes out. With the rise and fall of the push plate, the guide plate pushes outward in a step-like manner. This design tilts and guides the vertically upward airflow. By rotating the screw, the moving plate slides on the limit rod, facilitating the adjustment of the initial position of the extrusion rod. When the extrusion rod approaches and extrudes the inclined block, the subsequent guide plate is pushed open at a larger angle; when the extrusion rod moves away from the inclined block, the subsequent guide plate is pushed open at a smaller angle. This allows the protrusion distance of the guide plate to be adjusted to suit the protrusion positions of different electrical components, thus reducing the heat accumulation at the obstruction points of electrical components that still occur when the air is evenly distributed through the air guide plate. The stepped protrusions of the guide plate ensure that when air is guided at one point, other positions will not obstruct ventilation, preventing a significant reduction in ventilation speed and ensuring efficient ventilation and heat dissipation. At the same time, during air guidance, it is also convenient to blow the air towards the vertical side of the electrical component, increasing the contact area between the air and the electrical component and extending the contact time, thereby improving the heat dissipation effect.

[0020] 2. As the push plate is raised and lowered, it moves the mounting plate, which in turn moves the inner shaft and desiccant. The inner shaft then moves the gear unit, which meshes with the vertical rack, causing the gear unit and inner shaft to rotate. This causes the desiccant to rotate as it rises, allowing the upper and lower desiccants to alternate and avoid prolonged use on a single side. This process effectively absorbs moisture from inside the cabinet. The desiccant used is silica gel. The upper and lower desiccants also come into contact with the rising hot air. While absorbing moisture, the hot air heats the desiccant, helping to restore its moisture absorption capacity and further improving the dehumidification and drying effect.

[0021] 3. By setting up an exhaust system, when heat dissipation is needed, the operator starts the drive motor through the external control panel. The drive motor drives the fan blades to rotate, and the external air enters the cabinet through the air inlet and lower slot, then passes through the upper slot and air outlet, and is discharged into the exhaust box. The air inlet and upper slot are equipped with filters to reduce the entry of external dust and impurities. After the hot air and harmful waste gas inside the cabinet enter the exhaust box, they are adsorbed and purified by the adsorption plates. The adsorption plates use activated carbon or silica gel for adsorption treatment, and multiple adsorption plates can be set as needed. The treated gas is discharged through the exhaust pipe, realizing rapid ventilation and heat dissipation of the cabinet interior. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figure 1 - Figure 3 The present invention provides a technical solution: a heat-dissipating power distribution control device, including a base frame 1, an electrical component body 6 and a cabinet 2 fixedly installed on the top of the base frame 1, and a top plate 3 fixedly installed on the top of the cabinet 2.

[0038] like Figure 1 , Figure 4 - Figure 11 As shown, a guide assembly 7 is provided on one side of the front of the cabinet 2. The guide assembly 7 includes vertical plates 71 fixedly installed on both sides of the bottom surface of the cabinet 2. The vertical plates 71 serve as support and limit. A trapezoidal block 72 is evenly slidably installed on the side of the vertical plate 71 close to the electrical component body 6. One side of the trapezoidal block 72 protrudes outward to facilitate the smooth pressing of the trapezoidal block 72 by the subsequent pushing plate 719. A movable plate 76 is adjustablely installed on the side of the trapezoidal block 72 away from the vertical plate 71. Two pressing rods 77 are symmetrically fixedly connected to the side of the movable plate 76 close to the electrical component body 6.

[0039] The bottom surface of the cabinet 2 is also symmetrically and vertically fixed with side rods 78 on both sides, and a guide plate 715 is installed on the side where the two side rods 78 are close to each other.

[0040] The electrical component body 6 is fixedly installed on the back side of the cabinet 2. The cabinet door 4 is hinged to the front side of the cabinet 2. A sealing strip is fixedly connected to the inside of the cabinet door 4 to prevent water and dust from entering the cabinet 2. An exhaust box 5 is fixedly installed on the top of the top plate 3. Two limit rods 73 are slidably connected inside the trapezoidal block 72. One end of the limit rod 73 is fixedly connected to the vertical plate 71. A spring 74 is sleeved on the outside of the limit rod 73. The two ends of the spring 74 are fixedly connected to the vertical plate 71 and the trapezoidal block 72, respectively. The top and bottom of the trapezoidal block 72 near the vertical plate 71 are provided with slopes so that the push plate 719 will squeeze the trapezoidal block 72 when it rises and falls.

[0041] A lead screw 75 is rotatably connected to the middle of the side of the movable plate 76 away from the trapezoidal block 72. The movable plate 76 is threadedly connected to the lead screw 75, and the movable plate 76 is slidably connected to the limit rod 73. The lead screw 75 is used to adjust the initial position of the subsequent movable plate 76, which improves the flexibility of use. The guide assembly 7 also includes a fixing block 79 that is uniformly fixedly connected to the outside of the side rod 78. The top and bottom of the fixing block 79 are fixedly connected to a second spring 711, and the second spring 711 is slidably connected to the side rod 78.

[0042] A sliding block 710 is fixedly connected to the end of spring 711 away from the fixed block 79. An inclined block 712 and a side block 713 are fixedly connected to the outside of the sliding block 710. The upper and lower extrusion rods 77 are respectively flush with the two adjacent inclined blocks 712, so that the extrusion rods 77 can accurately extrude the inclined blocks 712 and reduce extrusion deviation.

[0043] A connecting block 714 is rotatably connected to one side of the side block 713. The connecting block 714 is fixedly connected to the guide plate 715. A center block 716 is fixedly connected to the side of the guide plate 715 away from the connecting block 714. The same auxiliary shaft 717 is rotatably connected between two adjacent center blocks 716.

[0044] The inner bottom surface of the cabinet 2 is also symmetrically fixedly installed with linear guide rails 718. The output end of the linear guide rails 718 is fixedly connected to a push plate 719. The linear guide rails 718 are used to maintain the stable lifting and lowering movement of the push plate 719. The side of the push plate 719 away from the vertical plate 71 is fixedly connected to a mounting plate 720. The outer side of the mounting plate 720 is rotatably connected to an inner shaft 721. The outer middle of the inner shaft 721 is fixedly connected to a gear part 722.

[0045] An installation cylinder 723 is fixedly connected between two inner shafts 721. The interior of the installation cylinder 723 is symmetrically filled with desiccant 724. The desiccant 724 is silica gel desiccant, which is filled at the top and bottom of the installation cylinder 723 by a curing agent. Vertical racks 725 are symmetrically fixedly installed on both sides of the inner wall of the cabinet 2. Two gear parts 722 are respectively meshed with the vertical racks 725 on both sides. The vertical racks 725 are located on the back side of the gear parts 722, maintaining stable meshing with the gear parts 722.

[0046] Example 1: As Figure 1 and Figure 3 - Figure 11 As shown, the operator starts the internal linear guide 718 through the external control panel. The linear guide 718 drives the push plate 719 to move up and down. When the push plate 719 rises, it will squeeze the bottom slope of one side of the trapezoidal block 72, causing the trapezoidal block 72 to slide on the limit rod 73 and stretch the spring 74. The trapezoidal block 72 drives the moving plate 76 to move through the lead screw 75. The moving plate 76 drives the pressing rod 77 to move, so that the two pressing rods 77 squeeze the upper and lower inclined blocks 712 respectively. The two inclined blocks 712 move closer to each other, and the inclined blocks 712 drive the sliding block 710 to slide on the side rod 78.

[0047] The sliding block 710 compresses the second spring 711. When the sliding block 710 moves, it drives the side block 713 to move. The two side blocks 713 will also move closer to each other. The side blocks 713 drive the connecting block 714 and the guide plate 715 to move. The guide plate 715 drives the center block 716 to rotate around the auxiliary shaft 717, so that the side of the upper and lower guide plates 715 that are close to each other tilts outward and pushes out.

[0048] When the push plate 719 separates from the trapezoidal block 72, the elastic force of the first spring 74 causes the trapezoidal block 72 to reset, and the second spring 711 causes the sliding block 710 to reset, so that the guide plate 715 no longer pushes out. As the push plate 719 rises and falls, the guide plate 715 pushes outward in a step-by-step manner, thereby tilting and guiding the vertically upward wind direction.

[0049] By rotating the lead screw 75, the moving plate 76 slides on the limiting rod 73, which facilitates the adjustment of the initial position of the extrusion rod 77. When the extrusion rod 77 approaches and extrudes the inclined block 712, the tilt angle at which the subsequent guide plate 715 is pushed open is greater. When the extrusion rod 77 moves away from the inclined block 712, the tilt angle at which the subsequent guide plate 715 is pushed open is smaller. This allows the protrusion distance of the guide plate 715 to be adjusted accordingly. This is used to adapt the airflow to the protrusion positions of different electrical component bodies 6, thereby reducing the situation where heat still accumulates at the obstruction position of the electrical component body 6 when the air is evenly distributed through the air guide plate.

[0050] The stepped protrusions of the guide plate 715 ensure that when air is guided at this point, other positions will not obstruct ventilation, thus preventing a significant reduction in ventilation speed and ensuring efficient ventilation and heat dissipation. At the same time, when guiding air, it is also convenient to blow the air towards the vertical side of the electrical component body 6, which increases the contact area between the air and the electrical component body 6 and prolongs the contact time, thereby improving the heat dissipation effect.

[0051] As the push plate 719 is raised and lowered, it drives the mounting plate 720 to move. The mounting plate 720 then drives the inner shaft 721 and the desiccant 724 to move. The inner shaft 721 drives the gear part 722 to move. The inner shaft 721 meshes with the vertical rack 725, causing the gear part 722 and the inner shaft 721 to rotate. This causes the desiccant 724 to rotate as it rises, allowing the upper and lower desiccant 724 to alternate, avoiding prolonged use on one side. This helps to absorb moisture inside the cabinet 2. The upper and lower desiccant 724 also come into contact with the rising hot air. While absorbing moisture, the hot air heats the desiccant 724, helping to restore its moisture absorption capacity and further improving the dehumidification and drying effect.

[0052] like Figure 1 , Figure 3 and Figure 12 - Figure 13 As shown, the exhaust box 5 is equipped with an exhaust assembly 8. The exhaust assembly 8 includes an air inlet 81 opened on one side inside the base frame 1. A drive motor 82 is symmetrically fixedly installed on the inner wall of the air inlet 81. The output end of the drive motor 82 is fixedly connected to a fan blade 83. The fan blade 83 is located above the drive motor 82. When the fan blade 83 rotates, external gas enters from the air inlet 81 and enters the exhaust box 5 from the air outlet 87 at the top.

[0053] The bottom of the cabinet 2 has a lower groove 84, the inside of the top plate 3 has an upper groove 85, the air inlet 81 is connected to the lower groove 84, the bottom of the exhaust box 5 has an air outlet 87, and the upper groove 85 is connected to the air outlet 87.

[0054] Both the air inlet 81 and the upper trough 85 are fixedly installed with filters 86 to reduce the entry of external dust and impurities. The exhaust box 5 is also fixedly installed with adsorption plates 88 in parallel inside. There are no fewer than three adsorption plates 88. An exhaust pipe 89 is fixedly installed on one side of the back of the exhaust box 5. The adsorption plates 88 are made of activated carbon or silica gel for adsorption treatment, and multiple adsorption plates 88 can be set as needed.

[0055] Example 2: Figure 3 and Figure 12 - Figure 13As shown, the operator starts the drive motor 82 through the external control panel. The drive motor 82 drives the fan blades 83 to rotate. External air enters the cabinet 2 through the air inlet 81 and the lower slot 84, and then passes through the upper slot 85 and the air outlet 87 before being discharged into the exhaust box 5. The hot air and harmful waste gas inside the cabinet 2 enter the exhaust box 5 and are then adsorbed and purified by the adsorption plate 88. The treated gas is discharged through the exhaust pipe 89, thus achieving rapid ventilation and heat dissipation of the cabinet 2.

[0056] Working principle: When using this device, firstly, as... Figure 1 - Figure 13 As shown, the operator starts the drive motor 82 via the external control panel. The drive motor 82 drives the fan blades 83 to rotate. External air enters the cabinet 2 through the air inlet 81 and the lower slot 84, then passes through the upper slot 85 and the air outlet 87, and is discharged into the exhaust box 5. The purified air is adsorbed by the adsorption plate 88 and then discharged through the exhaust pipe 89. At the same time, the internal linear guide rail 718 is activated. The linear guide rail 718 drives the push plate 719 to move up and down. When the push plate 719 rises, it will squeeze the bottom slope of one side of the trapezoidal block 72. Blocks 712 approach each other, and the inclined block 712 drives the sliding block 710 to slide on the side rod 78, causing the side of the upper and lower guide plates 715 that are close to each other to tilt outward and push out. When the push plate 719 separates from the trapezoidal block 72, the elastic force of spring one 74 causes the trapezoidal block 72 to return to its original position, and spring two 711 causes the sliding block 710 to return to its original position, so that the guide plate 715 no longer pushes out. As the push plate 719 rises and falls, the guide plates 715 are pushed outward in a step-like manner, thereby tilting and guiding the vertically upward wind direction. By rotating the lead screw 75, the moving plate 76 slides on the limiting rod 73, facilitating the adjustment of the initial position of the pressing rod 77. This allows for the adjustment of the protrusion distance of the guide plate 715, enabling adaptive airflow guidance for different protrusion positions of the electrical component body 6. When guiding airflow at this point, other positions will not obstruct ventilation, preventing a significant reduction in ventilation speed and ensuring efficient ventilation and heat dissipation. Furthermore, during airflow guidance, it is convenient to direct the airflow towards the vertical side of the electrical component body 6, increasing the contact area between the airflow and the electrical component body 6. At the same time, it also prolongs the contact time between the air body and the electrical component body 6. While pushing the plate 719 up and down, the mounting plate 720 drives the inner shaft 721 and the desiccant 724 to move. The inner shaft 721 meshes with the vertical rack 725, so that the desiccant 724 will rotate when it rises, so that the upper and lower desiccant 724 alternate, avoiding long-term use on one side. The upper and lower desiccant 724 will also come into contact with the rising hot air. While absorbing moisture, the hot air heats the desiccant 724, thereby helping to restore its moisture absorption capacity.
