Description

Technical Field

[0001] This utility model relates to the field of electrical control cabinet technology, specifically to an electrical control cabinet with dustproof and heat dissipation effects. Background Technology

[0002] As a core equipment carrier in industrial control and power distribution, electrical control cabinets contain integrated electrical components such as frequency converters, contactors, and relays that continuously generate heat during operation. If this heat cannot be dissipated in time, the increased temperature inside the cabinet can lead to component performance degradation, shortened lifespan, and even safety accidents such as short circuits and burnouts. Therefore, heat dissipation performance is one of the core design indicators for electrical control cabinets.

[0003] A search revealed CN212392490U, a protective device for an electrical control cabinet with shock absorption function, comprising a protective device body and an electrical control cabinet. A first connecting block is fixedly connected to the inner wall of the protective device body. This invention uses the first connecting block to drive a second connecting block, which in turn drives a piston. The piston drives a piston rod, a first sliding rod drives a fourth connecting block, which in turn drives a connecting rod. The connecting rod drives a third slider, which in turn drives a second spring. The deformation of the second spring generates a force opposite to the impact force on the electrical control cabinet. This solves the problem that electrical control cabinets are subject to various collisions due to external environmental influences during use, causing damage. Furthermore, most existing electrical control cabinets lack shock absorption devices, shortening their service life and wasting resources.

[0004] The aforementioned device addresses the issue that electrical control cabinets are susceptible to damage from various impacts during use due to external environmental influences. While electrical control cabinets typically have heat dissipation slots on their side walls to create airflow channels through natural convection or in conjunction with an internal fan, thus expelling internal heat to the outside, dust, lint, and other impurities from the external environment are usually fixedly installed inside the heat dissipation slots to prevent them from entering the cabinet with the airflow. However, over long-term use, a large amount of dust, oil particles, and other contaminants gradually accumulate on the surface of the dust filter, significantly increasing airflow resistance and causing a substantial decrease in the airflow efficiency of the heat dissipation slots.

[0005] In existing technologies, sliding brush strips are typically installed on the outside of the dustproof mesh. The brush strips are moved along the surface of the dustproof mesh by manual pushing or motor driving to sweep off the attached dust. During the brush sweeping or airflow blowing process, the stripped dust will form suspended dust. Since the heat sink and the dustproof mesh themselves are open structures to meet ventilation requirements, the dust can easily enter the electrical control cabinet through the gaps in the heat sink and the mesh of the dustproof mesh. The dust that enters the cabinet will gradually adhere to the pins, terminals, and circuit board surfaces of electrical components, which may lead to poor contact of the terminals, causing signal transmission failures or local overheating. In severe cases, dust accumulation around high-power components will hinder the heat dissipation of the components themselves. Utility Model Content

[0006] The purpose of this utility model is to provide an electrical control cabinet with dustproof and heat dissipation effects to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution: This utility model is an electrical control cabinet with dustproof and heat dissipation effects, comprising: Electrical control cabinet; The shielding component includes a baffle, a rotating rod, a rotating ring, and a guide rod. The rotating ring is located at the top and bottom of the inner surface of the electrical control cabinet. The rotating rod is rotatably connected to the middle of the rotating ring. The baffle is fixedly connected between the two rotating rods and is symmetrically distributed. The guide rod is fixed to the top of the rotating rod.

[0007] Furthermore, a supporting semi-ring is welded to the top of the electrical control cabinet, and a guide groove is provided inside the supporting semi-ring, with the guide rod slidably connected inside the guide groove.

[0008] Furthermore, a retaining ring is threaded onto the outer surface of the guide rod, and a rubber pad is adhered to one side of the retaining ring, the rubber pad being tightly fitted to the outer surface of the supporting half-ring.

[0009] Furthermore, a heat dissipation groove is provided in the middle of one side of the outer surface of the electrical control cabinet, and a dustproof net is detachably connected to the inner wall of the heat dissipation groove.

[0010] Furthermore, support blocks are fixedly connected to the upper and lower parts of one side of the outer surface of the electrical control cabinet, and a moving rod is provided between the two support blocks.

[0011] Furthermore, a support plate is provided on the outer side of the dustproof net, and a cleaning brush is adhered to the inner side of the support plate. The cleaning brush is attached to the surface of the dustproof net, and extension blocks are provided at both ends of the cleaning brush. Moving rings are provided at the top and bottom of the extension blocks, and the middle part of the moving rings is slidably connected to the outer surface of the moving rod.

[0012] Furthermore, it also includes a collection component, which includes a collection frame, a clamping frame, and a top frame.

[0013] Furthermore, a locking groove is provided at the top of the clamping frame, and a locking block is provided at the bottom of the top frame, the locking block being engaged inside the locking groove.

[0014] This utility model has the following beneficial effects: This invention, through its shielding components, allows operators to manually rotate the guide rods at both ends. The rotation of the rods and the rotating ring causes the baffles to open and close synchronously, sealing the inner surface of the heat dissipation trough. This effectively blocks suspended dust generated during cleaning from entering the electrical control cabinet. The baffles adhere to the inner surface of the heat dissipation trough, forming a sealed shield without obvious gaps. This effectively prevents dust from adhering to the pins, terminals, and circuit board surfaces of electrical components. It prevents malfunctions such as decreased insulation performance and poor wiring contact caused by dust accumulation, while also reducing dust coverage on the component's heat dissipation surface, ensuring the component's own heat dissipation effect.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0020] Please see Figure 1-4 As shown, this utility model is an electrical control cabinet with dustproof and heat dissipation effects, comprising: Electrical control cabinet 11; The shielding component includes a baffle 23, a rotating rod 24, a rotating ring 25, and a guide rod 26. The rotating ring 25 is disposed at the top and bottom of the inner surface of the electrical control cabinet 11. The rotating rod 24 is rotatably connected to the middle of the rotating ring 25. The baffle 23 is fixedly connected between the two rotating rods 24. The baffles 23 are symmetrically distributed. The guide rod 26 is fixed to the top of the rotating rod 24. The operator only needs to manually rotate the guide rods 26 at both ends, which will drive the baffles 23 to open and close synchronously through the cooperation of the rotating rod 24 and the rotating ring 25. This allows the baffles 23 at both ends to rotate synchronously and seal the inner surface of the heat dissipation slot 12, blocking the suspended dust generated during the cleaning process from entering the electrical control cabinet 11. The baffles 23 fit against the inner surface of the heat dissipation slot 12 to form a sealed shield without obvious gaps, effectively preventing dust from adhering to the pins, terminals and circuit board surfaces of electrical components. This not only prevents the components from deteriorating their insulation performance and causing poor wiring contact due to dust accumulation, but also reduces the coverage of dust on the heat dissipation surface of the components, ensuring the heat dissipation effect of the components themselves.

[0021] A supporting semi-ring 21 is welded to the top of the electrical control cabinet 11. A guide groove 22 is provided inside the supporting semi-ring 21, and the guide rod 26 is slidably connected inside the guide groove 22. When the baffle 23 is rotated, the guide rod 26 slides inside the guide groove 22, providing support.

[0022] A retaining ring 28 is threaded onto the outer surface of the guide rod 26. A rubber pad 27 is adhered to one side of the retaining ring 28 and is tightly attached to the outer surface of the supporting half ring 21. When the fixed ring 28 rotates to the point where it can no longer be pushed forward, the rubber pad 27 undergoes elastic deformation under the pressure, tightly adhering to the surface of the support plate 31 ring. Utilizing the static friction between the rubber pad 27 and the support plate 31 ring, as well as the self-locking property of the threaded connection, the positions of the guide rod 26 and the rotating rod 24 are locked, thereby fixing the sealing state of the baffle 23 and ensuring that the baffle 23 always remains in a sealed fit with the inner surface of the heat dissipation groove 12 during the cleaning process, without any gaps.

[0023] A heat dissipation groove 12 is provided in the middle of one side of the outer surface of the electrical control cabinet 11, and a dustproof net 13 is detachably connected to the inner wall of the heat dissipation groove 12. The electrical control cabinet 11 dissipates the heat generated inside to the outside through the heat dissipation slots 12, while using the dustproof net 13 to block the dust generated in the external environment.

[0024] Support blocks 33 are fixedly connected to the upper and lower parts of one side of the outer surface of the electrical control cabinet 11, and a moving rod 35 is provided between the two support blocks 33; A support plate 31 is provided on the outer side of the dustproof net 13. A cleaning brush 32 is bonded to the inner side of the support plate 31. The cleaning brush 32 is attached to the surface of the dustproof net 13. Extension blocks 34 are provided at both ends of the cleaning brush 32. Moving rings 36 are provided at the top and bottom of the extension blocks 34. The middle part of the moving rings 36 is slidably connected to the outer surface of the moving rod 35. The moving ring 36 slides up and down outside the moving rod 35, and the moving ring 36 drives the cleaning brush 32 to perform a reciprocating wiping motion along the surface of the dustproof net 13, thus peeling off the dust attached to the surface of the dustproof net 13.

[0025] Working principle: When dust accumulates on the surface of the dustproof net 13 to the point that it affects heat dissipation and cleaning is required, the operator first holds the guide rod 26 on the top of the electrical control cabinet 11 with both hands and rotates the guide rod 26 clockwise in sync. Since the guide rod 26 and the rotating rod 24 are an integrated structure, when the guide rod 26 rotates, it will drive the rotating rod 24 to rotate around the axis in the rotating ring 25 fixed inside the heat dissipation slot 12. The baffle 23 is welded and fixed between the two rotating rods 24 and rotates synchronously with the rotating rods 24 until both baffles 23 rotate to a position where they are completely in contact with the inner surface of the heat dissipation slot 12, thus completely sealing the inner channel of the heat dissipation slot 12. Next, rotate the fixing ring 28 clockwise. As the fixing ring 28 moves along the guide rod 26 thread toward the support half ring 21, the rubber pad 27 on one side of the fixing ring 28 gradually contacts and presses tightly against the support half ring 21 and the surface of the support plate 31 ring. Finally, the operator holds the support plate 31 connected to the moving ring 36 and pushes the support plate 31 up and down along the moving rod 35 axis, which drives the cleaning brush 32 to perform a reciprocating wiping motion along the surface of the dustproof net 13, peeling off the dust attached to the surface of the dustproof net 13.

[0026] During this process, because the inside of the heat sink 12 is completely sealed by the baffle 23, the suspended dust generated by the cleaning and stripping cannot enter the electrical control cabinet through the mesh of the heat sink 12 or the dustproof net 13. It will only accumulate on the outside of the dustproof net 13 and be transferred to the outside through the bottom of the heat sink 12 in an inclined manner, thus avoiding the pollution of electrical components inside the cabinet by dust from the source.

[0027] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes: The collection component includes a collection frame 41, a clamping frame 42, and a top frame 44. The clamping frame 42 is fixed to the lower part of one side of the outer surface of the electrical control cabinet 11, and the top frame 44 is fixed to both ends of the collection frame 41. The collection frame 41 is embedded and connected between the two clamping frames 42. Because the bottom of the heat sink 12 is pre-tilted at an angle and the inclined surface is smooth, dust will not accumulate in the heat sink 12 under the action of gravity, but will slide down naturally along the inclined surface, forming a directional flow path. The dust will gradually slide from the upper inclined section of the heat sink 12 to the bottom outlet end and be transferred to the inside of the collection frame 41.

[0028] The top of the clamping frame 42 is provided with a locking groove 43, and the bottom of the top frame 44 is provided with a locking block 45, which is engaged inside the locking groove 43. The locking block 45 is made of elastic plastic. During assembly, the collection frame 41 is pushed in along the bottom guide rail of the heat dissipation groove 12. Under the action of the squeezing force, the locking block 45 is locked into the locking groove 43, so as to achieve a stable installation of the collection frame 41 and prevent the collection frame 41 from shifting or dust from leaking out due to cleaning or equipment vibration.

[0029] Working principle: After the cleaning brush 32 removes the dust from the surface of the dustproof net 13, the resulting loose dust and lumpy dust will fall directly to the bottom of the heat sink 12. Due to the preset tilt angle at the bottom of the heat sink 12, the dust will not accumulate in the heat sink 12 under the action of gravity, but will slide naturally along the tilted surface and finally fall into the inside of the collection frame 41. Finally, hold both sides of the collection frame 41 and apply a pulling force in the vertical upward direction. The elastic locking blocks 45 at both ends of the collection frame 41 will overcome their own elastic deformation and come out of the locking groove 43, releasing the fixed relationship between the collection frame 41 and the heat sink 12.

[0030] This step not only solves the problem of dust pollution during cleaning, but also makes dust cleaning more convenient, while preventing dust from entering the electrical control cabinet 11 and ensuring the heat dissipation and operational safety of the electrical components inside the cabinet.
