Description

Technical Field

[0001] This invention relates to the field of heat dissipation technology for electrical control boxes, and more specifically, to a heat dissipation structure based on an electrical control box. Background Technology

[0002] As the core equipment for centralized control, protection and distribution of circuits in a power system, the electrical control box is widely used in many fields such as industrial automation, building power distribution, and transportation. It integrates a variety of electronic components such as circuit breakers, contactors and relays. During long-term operation, these components will continuously generate heat. If the heat cannot be dissipated in time, the temperature inside the box will rise sharply, which will not only accelerate the aging of electronic components and reduce their performance and reliability, but may also cause serious faults such as short circuits and component burnout, or even cause safety accidents. Therefore, timely heat dissipation of the electrical control box is necessary.

[0003] A search revealed Chinese patent application number CN202220028404.1, which discloses an electrical control box with a heat dissipation structure. The box includes a main body with several horizontal first-strip ventilation slots formed on two opposite side walls. These first-strip ventilation slots on each side wall are evenly spaced along the vertical direction. Two sets of adjustment devices are also included, each set positioned on one of the two opposite side walls of the main body. Each set of adjustment devices is used to adjust the ventilation volume of the first-strip ventilation slots.

[0004] Although the aforementioned patent describes several first-strip ventilation slots on the two opposite side walls of the main body of the electrical control box, allowing internal airflow and enhancing heat dissipation, and two sets of adjustment devices to control the ventilation volume of the first-strip ventilation slots, allowing for adjustment according to actual conditions, thus better protecting the main body of the electrical control box and greatly extending the service life of internal electronic components, and the main control device to synchronously control the two sets of adjustment devices, requiring operators to use special tools to start the main control device, improving safety and preventing accidental operation by pedestrians, the following shortcomings still exist during use: 1. Inconvenient maintenance of the heat dissipation structure; cumbersome and time-consuming operation when repairing or replacing filter components; 2. Poor heat dissipation and dust prevention effect; dust easily enters the box, affecting the lifespan of electronic components, and the heat dissipation efficiency is low.

[0005] Therefore, there is an urgent need for a heat dissipation structure based on the electrical control box to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a heat dissipation structure based on an electrical control box to solve the problems mentioned in the background art.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0008] A heat dissipation structure based on an electrical control box includes an electrical control box housing, wherein a fixing frame is fixedly connected to the top wall of the electrical control box housing, and further includes:

[0009] A limiting installation assembly includes a limiting block symmetrically slidably connected to the inner wall of the electrical control box housing, a strong spring fixedly connected to the outer wall of the limiting block, and the end of the strong spring away from the limiting block being fixedly connected to the electrical control box housing, a pressure block fixedly connected to the outer wall of the limiting block, and the pressure block being slidably connected to the electrical control box housing, and an installation plate slidably connected to the limiting block through a limiting hole;

[0010] An extrusion release assembly is disposed on the inner wall of the electrical control box housing, and the extrusion release assembly cooperates with the limiting installation assembly;

[0011] Adjust the cleaning component, which is located on the outer wall of the mounting plate.

[0012] As a preferred technical solution of this application, the extrusion release assembly includes an adjusting screw that is uniformly rotatably connected to the inner wall of the electrical control box housing. The outer wall of the adjusting screw is threaded with uniformly distributed extrusion blocks, and the extrusion blocks are slidably connected to the electrical control box housing. The outer wall of the extrusion blocks abuts against the outer wall of the pressure block. The top wall of the adjusting screw is fixedly connected with a driven groove wheel, and the driven groove wheels are connected to each other by a positive belt drive with a protrusion.

[0013] As a preferred technical solution of this application, the adjustment and cleaning assembly includes a rectangular adjustment plate slidably connected to the outer wall of the mounting plate, the outer wall of the rectangular adjustment plate having uniformly distributed movable ventilation slots, and uniformly distributed brushes fixedly connected to the outer wall of the rectangular adjustment plate.

[0014] As a preferred technical solution of this application, the outer wall of the electrical control box housing is provided with uniformly distributed fixed ventilation slots, and a honeycomb filter plate is fixedly connected to the inner wall of the fixed ventilation slot, and the outer wall of the honeycomb filter plate abuts against the outer wall of the brush.

[0015] As a preferred technical solution of this application, a drive bevel gear is rotatably connected to the outer wall of the fixed frame, a drive block A is fixedly connected to the top wall of the drive bevel gear, a linkage rod is also rotatably connected to the outer wall of the fixed frame, a driven bevel gear is fixedly connected to the outer wall of the linkage rod, and the outer wall of the driven bevel gear meshes with the outer wall of the drive bevel gear, a rotating block is fixedly connected to the outer wall of the linkage rod, and a drive rod is fixedly connected to the outer wall of the rotating block.

[0016] As a preferred technical solution of this application, the top wall of the electrical control box housing is slidably connected with symmetrically distributed vertical connecting plates, the vertical connecting plates are slidably connected to the drive rod, and the vertical connecting plates are slidably connected to the rectangular adjustment plate through the linkage groove.

[0017] As a preferred technical solution of this application, a drive block B is fixedly connected to the top wall of the driven groove wheel located at the right front end, and both the drive block B and the drive block A are driven by professional tools.

[0018] As a preferred technical solution of this application, the top wall of the electrical control box housing is fixedly connected with symmetrically distributed positioning blocks, and the positioning blocks are rotatably connected to the linkage rod.

[0019] As a preferred technical solution of this application, the outer wall of the electrical control box housing is fixedly connected with symmetrically distributed dust baffles, which are used to reduce dust from entering the fixed ventilation slot.

[0020] As a preferred technical solution of this application, a base is fixedly connected to the outer wall of the electrical control box housing, and a dustproof shell is also fixedly connected to the outer wall of the electrical control box housing.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] In the scheme of this application:

[0023] 1. By using the set limit mounting component and the extrusion release component, when the filter component needs to be repaired or replaced, the drive block B drives the driven groove wheel and the convex positive belt to drive the adjusting screw to rotate synchronously. The extrusion block moves inward to extrude the pressure block, so that the limit block overcomes the pre-tightening force of the strong spring and slides to both sides to disengage from the limit hole, and the mounting plate can be quickly removed. The whole process does not require complicated tools and cumbersome operations, making the disassembly and installation of the mounting plate and related components simple and quick, reducing maintenance costs. When the equipment needs to be repaired or the filter component needs to be replaced, the operation can be completed quickly, reducing downtime. This solves the problems of inconvenient maintenance of heat dissipation structure and cumbersome and time-consuming operation when repairing or replacing filter components in the existing technology.

[0024] 2. The honeycomb filter effectively filters dust, and the dust baffle further reduces dust entry, protects electronic components, and extends service life. The ventilation structure design allows hot air to rise and be expelled naturally, while cold air enters from the bottom, forming a good convection circulation and improving heat dissipation efficiency. This solves the problems of poor heat dissipation and dust prevention in existing technologies, where dust easily enters the box, affecting the life of electronic components, and has low heat dissipation efficiency.

[0025] 3. The automatic cleaning of the honeycomb filter plate is achieved by setting the adjustment and cleaning components, which eliminates the need for frequent manual maintenance, ensures the stability of ventilation efficiency, and the reciprocating motion of the brush can deeply clean the pores of the honeycomb filter plate, ensuring that dust does not accumulate and cause blockage.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention.

[0038] like Figure 1-9As shown, the heat dissipation structure based on the electrical control box proposed in this embodiment includes an electrical control box housing 1, a fixing frame 6 fixedly connected to the top wall of the electrical control box housing 1, and further includes:

[0039] The limiting installation assembly includes a limiting block 23 symmetrically slidably connected to the inner wall of the electrical control box housing 1. A strong spring 25 is fixedly connected to the outer wall of the limiting block 23, and the end of the strong spring 25 away from the limiting block 23 is fixedly connected to the electrical control box housing 1. A pressure block 24 is fixedly connected to the outer wall of the limiting block 23, and the pressure block 24 is slidably connected to the electrical control box housing 1. The limiting block 23 is slidably connected to the mounting plate 4 through the limiting hole 29. During installation, the mounting plate 4 is slid in, and when the mounting plate 4 presses and drives the limiting block 23 to slide, it also presses the strong spring 25. At this time, the strong spring 25 stores elastic energy. When the limiting block 23 corresponds to the limiting hole 29, the mounting plate 4 is limited and fixed. The installation is simple and quick.

[0040] The extrusion release component is installed on the inner wall of the electrical control box housing 1, and the extrusion release component cooperates with the limit installation component;

[0041] Adjust the cleaning component, which is located on the outer wall of the mounting plate 4.

[0042] like Figure 4 , Figure 8 and Figure 9 As shown, in a preferred embodiment, based on the above method, the extrusion release assembly further includes an adjusting screw 18 that is rotatably connected to the inner wall of the electrical control box housing 1. The outer wall of the adjusting screw 18 is threaded with evenly distributed extrusion blocks 22, and the extrusion blocks 22 are slidably connected to the electrical control box housing 1. The outer wall of the extrusion blocks 22 abuts against the outer wall of the pressure block 24. The top wall of the adjusting screw 18 is fixedly connected with a driven groove wheel 19. The driven groove wheels 19 are connected to each other by a convex positive belt 20. Using a professional tool to rotate the drive block B21, all adjusting screws 18 are driven to rotate synchronously through the driven groove wheels 19 and the convex positive belt 20. The extrusion blocks 22 move along the adjusting screw 18 and extrude the pressure block 24, causing the limiting block 23 to overcome the elastic force of the strong spring 25 and slide to both sides, disengaging from the limiting hole 29. This allows for quick disassembly of the mounting plate 4 and related components, facilitating maintenance. After disassembly, the elastic force of the strong spring 25 can automatically reset the limiting block 23, preparing it for the next installation.

[0043] like Figure 6 and Figure 7As shown, in a preferred embodiment, based on the above method, the adjustment and cleaning assembly further includes a rectangular adjustment plate 26 slidably connected to the outer wall of the mounting plate 4. The outer wall of the rectangular adjustment plate 26 has evenly distributed movable ventilation slots 27. Evenly distributed brushes 28 are fixedly connected to the outer wall of the rectangular adjustment plate 26. When the drive bevel gear 12 rotates, it drives the linkage rod 8 to rotate through the driven bevel gear 13, causing the rotating block 10 to rotate accordingly. The drive rod 14 pushes the vertical connecting plate 9 to reciprocate. The vertical connecting plate 9 drives the rectangular adjustment plate 26 to slide through the linkage slot 15, causing the brushes 28 to move back and forth on the surface of the honeycomb filter plate 17, cleaning the dust on the filter plate and ensuring ventilation efficiency. During equipment operation, the drive block A11 can be driven periodically or as needed using professional tools to achieve automatic cleaning.

[0044] like Figure 7 As shown, in a preferred embodiment, based on the above method, the outer wall of the electrical control box housing 1 is further provided with uniformly distributed fixed ventilation slots 16. A honeycomb filter plate 17 is fixedly connected to the inner wall of the fixed ventilation slot 16, and the outer wall of the honeycomb filter plate 17 abuts against the outer wall of the brush 28. Outside air enters the electrical control box housing 1 through the fixed ventilation slots 16. The honeycomb filter plate 17 filters the dust in the air to prevent dust from entering the housing and affecting the electronic components. When the equipment is running, the heat generated inside causes the air to rise and be discharged from the top, forming natural convection. Outside cold air continuously enters from the fixed ventilation slots 16 to achieve heat exchange. When the rectangular adjustment plate 26 slides, the overlap between the moving ventilation slot 27 on its surface and the fixed ventilation slot 16 changes, thereby adjusting the air intake to adapt to different heat dissipation requirements. When the equipment is running under high load, the overlap can be increased to increase the ventilation volume; when the load is low, the overlap can be reduced to reduce energy consumption and reduce dust entry.

[0045] like Figure 6 As shown, in a preferred embodiment, based on the above method, a driving bevel gear 12 is rotatably connected to the outer wall of the fixed frame 6, and a driving block A11 is fixedly connected to the top wall of the driving bevel gear 12. A linkage rod 8 is also rotatably connected to the outer wall of the fixed frame 6. A driven bevel gear 13 is fixedly connected to the outer wall of the linkage rod 8, and the outer wall of the driven bevel gear 13 meshes with the outer wall of the driving bevel gear 12. A rotating block 10 is fixedly connected to the outer wall of the linkage rod 8, and a driving rod 14 is fixedly connected to the outer wall of the rotating block 10. When the driving bevel gear 12 rotates, it drives the linkage rod 8 to rotate through the driven bevel gear 13, and the rotating block 10 rotates accordingly. The driving rod 14 pushes the vertical connecting plate 9 to reciprocate. The vertical connecting plate 9 drives the rectangular adjusting plate 26 to slide through the linkage groove 15. When the rectangular adjusting plate 26 slides, the overlap between the movable ventilation groove 27 and the fixed ventilation groove 16 on its surface changes, thereby adjusting the air intake volume to adapt to different heat dissipation requirements.

[0046] like Figure 2As shown, in a preferred embodiment, based on the above method, the top wall of the electrical control box housing 1 is further provided with symmetrically distributed vertical connecting plates 9. The vertical connecting plates 9 are slidably connected to the drive rod 14. The vertical connecting plates 9 are slidably connected to the rectangular adjustment plate 26 through the linkage groove 15. When the mounting plate 4 is installed, the vertical connecting plates 9 slide to drive the rectangular adjustment plate 26 to slide through the holes in the linkage groove 15 (not shown in the diagram), which facilitates the subsequent cleaning of the honeycomb filter plate 17 and the adjustment of the ventilation volume.

[0047] like Figure 2 As shown, in a preferred embodiment, based on the above method, a drive block B21 is further fixedly connected to the top wall of the driven groove wheel 19 located at the front right side. Both the drive block B21 and the drive block A11 are driven by a professional tool. The unique groove contour of the drive block B21 ensures accurate and stable power input while preventing accidental contact by passersby. When the drive block B21 is rotated using a special tool, the power is immediately transmitted to the driven groove wheel 19 connected to it. Multiple driven groove wheels 19 are tightly engaged with the protrusions on the protrusion belt 20 through surface grooves, forming an efficient closed-loop transmission network, realizing the synchronous transmission of power to each adjusting screw 18 with zero delay and zero slippage.

[0048] like Figure 2 As shown, in a preferred embodiment, based on the above method, the top wall of the electrical control box housing 1 is further provided with symmetrically distributed positioning blocks 7, and the positioning blocks 7 are rotatably connected to the linkage rod 8. The positioning blocks 7 adopt a high-strength metal structure and have built-in deep groove ball bearings, which are tightly matched with the linkage rod 8. This design not only ensures that the linkage rod 8 can rotate flexibly with the bearing with a low coefficient of friction, but also prevents it from shaking during rotation through precise axial and radial limiting. When the driving bevel gear 12 drives the driven bevel gear 13 to drive the linkage rod 8 to rotate, the positioning blocks 7, with their robust support structure, effectively withstand the torque and centrifugal force generated during rotation, ensuring that the linkage rod 8 and components such as the rotating block 10 and the driving rod 14 maintain the correct relative position. Even under long-term operation of the electrical control box or under the influence of external vibration, the stability and reliability of the entire transmission system can be maintained.

[0049] like Figure 1As shown, in a preferred embodiment, based on the above method, a further step is to fix symmetrically distributed dust baffles 5 to the outer wall of the electrical control box housing 1. The dust baffles 5 are used to reduce dust entering the fixed ventilation slot 16. The dust baffles 5 adopt a unique arc-shaped structure design. This design is not only aesthetically pleasing but also exhibits excellent performance in terms of waterproofing and dustproofing. Its arc-shaped contour can effectively change the airflow direction. When external airflow carrying dust or rainwater approaches the electrical control box, the arc-shaped dust baffles 5 allow the airflow to flow along the arc of the plate surface. Dust is difficult to adhere due to inertia, while rainwater slides off. The fixed ventilation slot 16 prevents dust and rainwater from directly contacting the control box. At the same time, the arc-shaped structure and the close fit design of the control box housing 1 form a tight protective barrier. Combined with the honeycomb filter plate 17, the dustproof effect is further enhanced, preventing rainwater from seeping into the box and corroding electronic components. In complex outdoor environments or humid industrial sites, the arc-shaped dust baffle 5 can continuously provide reliable protection for the control box, reduce the risk of failure caused by dust accumulation and rainwater intrusion, greatly improve the stability and service life of the control box, and ensure that the internal electronic components work efficiently in a safe and clean environment.

[0050] like Figure 1 As shown in the preferred embodiment, based on the above method, a base 2 is fixedly connected to the outer wall of the electrical control box housing 1, and a dustproof shell 3 is also fixedly connected to the outer wall of the electrical control box housing 1. The dustproof shell 3 provides all-round protection for the core structure at the top of the electrical control box housing 1. It is integrally molded from high-strength, corrosion-resistant engineering plastic material, which can effectively resist external impacts and prevent water accumulation from corroding the top components of the electrical control box. The dustproof shell 3 tightly wraps the key transmission components such as the fixing bracket 6, the drive bevel gear 12, and the linkage rod 8. By adding multiple layers of sealing strips at the joints, a physical dustproof barrier is formed to prevent dust, sand, and other impurities from entering the interior and interfering with the operation of the structure. At the same time, the surface of the dustproof shell 3 is also treated with anti-ultraviolet rays, so that even if it is exposed to strong outdoor light for a long time, it will not age or crack. It always maintains the stable protection of the top structure of the electrical control box, ensuring that the control components such as the drive block A11 and the drive block B21 are not affected by external factors, so that the limit installation components, the extrusion release components, and other structures can operate continuously and stably, significantly reducing the probability of equipment failure caused by external environmental factors and extending the overall service life of the electrical control box.

[0051] Specifically, the heat dissipation structure based on the electrical control box is used as follows: heat dissipation and dust prevention: outside air enters the electrical control box housing 1 through the fixed ventilation slot 16, and the honeycomb filter plate 17 filters the dust in the air to prevent dust from entering the box and affecting the electronic components. When the equipment is running, the heat generated inside causes the air to rise and be discharged from the top, forming natural convection. Outside cold air continuously enters through the fixed ventilation slot 16 to achieve heat exchange. When the drive bevel gear 12 rotates, it drives the linkage rod 8 to rotate through the driven bevel gear 13, and the rotating block 10 rotates accordingly. The drive rod 14 pushes the vertical connecting plate 9 to reciprocate. The vertical connecting plate 9 drives the rectangular adjusting plate 26 to slide through the linkage slot 15, so that the brush 28 moves back and forth on the surface of the honeycomb filter plate 17 to clean the dust on the filter plate and ensure ventilation efficiency. During equipment operation, the drive block A11 can be automatically cleaned periodically or as needed using specialized tools. When the rectangular adjustment plate 26 slides, the overlap between the moving ventilation slot 27 and the fixed ventilation slot 16 on its surface changes, thereby adjusting the air intake to adapt to different heat dissipation requirements. When the equipment is running under high load, the overlap can be increased to increase ventilation; under low load, the overlap can be reduced to reduce energy consumption and dust entry. During installation, the mounting plate 4 is slid in, and when the mounting plate 4 presses, it drives the limit block 23 to slide, compressing the strong spring 25. At this time, the strong spring 25 stores elastic energy. When the limiting block 23 corresponds to the limiting hole 29, the mounting plate 4 is fixed in place. Installation is simple and quick. During disassembly, a professional tool is used to rotate the drive block B21. The driven groove wheel 19 and the convex positive belt 20 drive all the adjusting screws 18 to rotate synchronously. The pressing block 22 moves along the adjusting screw 18 and presses the pressure block 24, causing the limiting block 23 to slide to both sides against the elastic force of the strong spring 25 and disengage from the limiting hole 29. The mounting plate 4 and related components can then be quickly disassembled for easy maintenance. After disassembly, the elastic force of the strong spring 25 can automatically reset the limiting block 23, preparing it for the next installation.

[0052] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described herein. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present invention, as well as all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present invention.
