Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, and in particular to an electrical control distribution cabinet with uniform heat dissipation. Background Technology

[0002] Cigarette manufacturing enterprises utilize a large number of mechanical and electrical equipment. The operation of this equipment requires electrical control to ensure its normal operation and safe production. Maintenance of this equipment is also necessary during actual production. Electrical control systems typically utilize distribution cabinets. These cabinets, through internal circuit connections and control components, achieve centralized control and protection of electrical equipment such as motors, pumps, and fans. They can control the starting, stopping, forward and reverse rotation, and speed adjustment of the equipment, ensuring its normal operation.

[0003] Patent CN216162119U discloses a power distribution cabinet with convenient internal installation of control electrical appliances. The cabinet includes a power distribution cabinet and a control electrical appliance mounting bracket. The control electrical appliance mounting bracket is slidably installed inside the power distribution cabinet. A support frame is fixedly installed inside the control electrical appliance mounting bracket. A crossbar is uniformly rotatably installed inside the support frame. A positioning frame is slidably installed at the bottom center of the support frame. A first tension spring is fixedly installed at the bottom of the positioning frame. Toothed grooves are symmetrically opened on the central axis of the side edge of the support frame. Limiting slides are opened through the two end faces of the support frame. A first limiting guide rod is fixedly installed at the internal center of the support frame.

[0004] While the aforementioned distribution cabinet allows for easy installation of control electrical components within the support frame through sliding and rotating adjustments of the crossbar, thus improving work efficiency and reducing labor intensity, the electrical components inside generate significant heat during actual operation. If this heat cannot be effectively dissipated in a timely manner, it will severely impact the performance and lifespan of these components, and may even lead to safety accidents. Although some distribution cabinets with heat dissipation features exist, uneven airflow distribution often results in localized overheating, causing performance degradation or damage to some electrical components. Furthermore, filters are prone to clogging with dust over long-term use, affecting ventilation. Traditional cleaning methods rely heavily on periodic manual cleaning, which is not only labor-intensive and resource-intensive but also cannot guarantee constant filter cleanliness. In addition, existing support plates lack flexibility in installation and adjustment, failing to adequately accommodate the installation needs of different sized electrical components and hindering the full and rational utilization of the cabinet space. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an electrical control distribution cabinet with uniform heat dissipation, which can extract hot air from the distribution cabinet in a relatively uniform manner and can clean the filter screen to remove dust, thereby improving heat dissipation performance.

[0006] The present invention solves the above-mentioned technical problems through the following technical means:

[0007] This invention discloses an electrical control distribution cabinet with uniform heat dissipation, comprising a cabinet body, a fixed frame on one side of the cabinet body, fans on the upper and lower sides of the fixed frame, two scrapers fixedly connected to one side surface of each of the two fans, and air guide plates fixedly connected to the front surface of each of the two fans for guiding airflow. A base plate is fixedly connected inside the cabinet body, and two support frames are fixedly connected to the upper surface of the base plate for support. A bearing plate is movably connected between the two support frames, and a hollow plate is fixedly connected to the lower surface of the bearing plate. Two connecting plates are movably engaged inside the hollow plate, and two return springs are fixedly connected to the opposite surfaces of the two connecting plates. Push rods are fixedly connected to the front surface of the two connecting plates. A filter screen is provided inside the cabinet body, and the filter screen is configured to cooperate with the two pairs of scrapers.

[0008] During operation, when internal components of the cabinet require heat dissipation, the control system activates two fans. The piston of the activating cylinder moves a fixed support frame, which in turn moves the two fans in a straight, reciprocating motion. The airflow from the fans covers different areas of the cabinet, achieving uniform heat dissipation, improving cooling efficiency, preventing overheating of electrical components that could lead to performance degradation or malfunction, and extending the overall lifespan of the components. Simultaneously, two pairs of scrapers fixed to the fans move, contacting the filter surface and cleaning accumulated dust and debris, preventing filter clogging and ensuring smooth airflow into the cabinet. This maintains good heat dissipation and ensures the electrical equipment inside the cabinet operates within a suitable temperature environment.

[0009] When the fan is operating, the guide vanes fixed to its surface can optimize the airflow direction, so that the cool air is more evenly distributed in the cabinet body, avoiding local overheating or overcooling, and improving the temperature uniformity inside the electrical cabinet. This is conducive to the operation of electrical equipment in a more stable temperature environment, reducing the risk of equipment performance degradation or failure due to excessive temperature differences.

[0010] Furthermore, a limiting plate is fixedly connected to the lower surface of the bearing plate; the limiting plate is movably engaged with two push rods.

[0011] Furthermore, a connecting frame is fixedly connected to the cabinet body; a cylinder is fixedly installed on the surface of the connecting frame.

[0012] Furthermore, the cylinder piston is fixedly connected to the mounting bracket.

[0013] Furthermore, two sliders for limiting the position are fixedly connected to the rear surface of the fixing frame.

[0014] Furthermore, a slot is provided on the front surface of the connecting frame; wherein the slot is movably connected to two sliders.

[0015] Furthermore, two positioning blocks are fixedly connected to the lower surface of the support plate; the two positioning blocks are respectively movably engaged with the two connecting plates.

[0016] Furthermore, a connecting strip is fixedly connected inside the hollow plate; the connecting strip is fixedly connected to two pairs of reset springs.

[0017] Furthermore, a set of limiting blocks is fixedly connected to the back sides of both connecting plates.

[0018] Furthermore, each of the two support frames has a set of limiting grooves on its opposite surfaces; the two sets of limiting grooves are respectively engaged with two sets of limiting blocks. In use, the electrical components inside the cabinet are mounted on the support plate. The relative movement of the two push rods moves the fixed connecting plate together, compressing the two pairs of return springs. At this point, the two sets of limiting blocks disengage from the two sets of limiting grooves on the two support frames, opening the limits. The support plate can then be disassembled or moved up and down. Stability is ensured by two positioning blocks during the movement of the two connecting plates. The required number of support plates are placed according to the quantity and volume of the installed electronic components, allowing for a reasonable layout and full utilization of the vertical space of the cabinet, avoiding space waste. During later maintenance and inspection, the easily adjustable support plates provide convenience for maintenance personnel, allowing them to adjust the support plates to a suitable height, making it easier for them to access the components requiring repair and improving maintenance efficiency.

[0019] The beneficial effects of this invention are:

[0020] 1. This invention starts the operation of two fans by controlling the system to dissipate heat. The piston of the cylinder is activated to drive the fixed frame to move together. During the movement of the fixed frame, the two fans move back and forth in a straight line. The air blown by the two fans during the movement can cover different areas of the cabinet body, so as to achieve uniform heat dissipation inside the cabinet body, improve the heat dissipation effect, prevent the performance of electrical components from deteriorating or malfunctioning due to local overheating of the cabinet body, and extend the overall service life of electrical components.

[0021] 2. During the movement of the two connecting plates in this invention, stability is ensured by two positioning blocks. The required number of support plates are placed according to the number and volume of the installed electronic components, and a reasonable layout is made to make full use of the vertical space of the cabinet body and avoid space waste. In the later maintenance and inspection process, the easily adjustable support plates provide convenience for maintenance personnel. The support plates can be adjusted to a suitable height, so that maintenance personnel can more easily approach the components that need to be repaired and improve maintenance efficiency.

[0022] 3. When the fan of the present invention is in operation, the guide plate fixed on its surface can optimize the airflow direction, so that the cold air is more evenly distributed in the cabinet body, avoiding local overheating or overcooling, and improving the temperature uniformity inside the electrical cabinet. This is beneficial for the electrical equipment to operate in a more stable temperature environment and reduces the risk of equipment performance degradation or failure due to excessive temperature differences.

[0023] 4. During the movement of the two fans of the present invention, the two pairs of scrapers fixed on them also move accordingly. The two pairs of scrapers are in contact with the surface of the filter screen. As they move, they will clean the dust or foreign objects accumulated on the surface of the filter screen, thereby preventing the filter screen from becoming clogged. This ensures that air can smoothly pass through the filter screen into the cabinet body, maintain good heat dissipation performance, and ensure that the electrical equipment inside the cabinet body operates in a suitable temperature environment.

A mounting bracket 6 for support is located on the right side of the main body 1. Fans 5 are mounted on both the upper and lower sides of the mounting bracket 6. Two cleaning scrapers 21 are fixedly connected to the left surface of each fan 5. A guide plate 20 for airflow is fixedly connected to the front surface of each fan 5.

A support plate 9 is movably connected between the two support brackets 3. A hollow plate 16 is fixedly connected to the lower surface of the support plate 9, and the hollow plate 16 is movably latched within it. There are two connecting plates 12, and two return springs 18 are fixedly connected to the opposite surfaces of the two connecting plates 12. Push rods 14 are fixedly connected to the front surfaces of the two connecting plates 12. A filter screen 4 is installed inside the cabinet body 1. The filter screen 4 is in contact with two pairs of scrapers 21. A limit plate 15 is fixedly connected to the lower surface of the bearing plate 9.

A cylinder 7 is fixedly installed on the front surface of the connecting frame 8. The piston of the cylinder 7 is fixedly connected to the fixed frame 6. Two sliders 22 for limiting are fixedly connected to the rear surface of the fixed frame 6.

[0035] During use, when the internal components of the cabinet body 1 need heat dissipation, the control system starts the operation of two fans 5 to begin heat dissipation. The piston of the cylinder 7 is activated, which drives the fixed bracket 6 to move together. During the movement of the fixed bracket 6, the two fans 5 move back and forth in a straight line. The air blown by the two fans 5 can cover different areas of the cabinet body 1, achieving uniform heat dissipation inside the cabinet body 1, improving the heat dissipation effect, preventing the performance degradation or failure of electrical components caused by local overheating of the cabinet body 1, and extending the overall service life of electrical components. During the movement of the two fans 5, the two pairs of scrapers 21 fixed on them also move. The two pairs of scrapers 21 are in contact with the surface of the filter screen 4. As they move, they will clean the dust or foreign objects accumulated on the surface of the filter screen 4, thereby preventing the filter screen 4 from becoming clogged, ensuring that air can smoothly pass through the filter screen 4 into the cabinet body 1, maintaining good heat dissipation performance, and ensuring that the electrical equipment inside the cabinet body 1 operates in a suitable temperature environment.

[0036] When the fan 5 is in operation, the guide plate 20 fixed on its surface can optimize the airflow direction, so that the cold air is more evenly distributed in the cabinet body 1, avoiding local overheating or overcooling, and improving the temperature uniformity in the electrical cabinet. This is conducive to the operation of electrical equipment in a more stable temperature environment and reduces the risk of equipment performance degradation or failure due to excessive temperature differences.

[0037] In this embodiment, a slot 23 is provided on the front surface of the connecting frame 8, and the slot 23 is movably connected to two sliders 22. Two positioning blocks 13 are fixedly connected to the lower surface of the bearing plate 9, and the two positioning blocks 13 are respectively movably engaged with the two connecting plates 12. A connecting strip 19 is fixedly connected inside the hollow plate 16, and the connecting strip 19 is fixedly connected to two pairs of return springs 18. A set of limiting blocks 17 are fixedly connected to the opposite sides of the two connecting plates 12. A set of limiting grooves 10 are provided on the opposite sides of the two support frames 3, and the two sets of limiting grooves 10 are respectively movably engaged with the two sets of limiting blocks 17. During use, the electrical components inside the cabinet body 1 are installed on the bearing plate 9, and the fixed connecting plates 12 are driven by the relative movement of the two push rods 14. The two pairs of return springs 18 are compressed as they move together. At this time, the two sets of limit blocks 17 will disengage from the two sets of limit slots 10 opened on the two support frames 3, and the limit will be opened. At this time, the support plate 9 can be disassembled or moved up and down. During the movement of the two connecting plates 12, the stability is ensured by the two positioning blocks 13. The required number of support plates 9 are placed according to the number and volume of the installed electronic components, and a reasonable layout is made to make full use of the vertical space of the cabinet body 1 and avoid space waste. In the later maintenance and inspection process, the easily adjustable support plate 9 provides convenience for maintenance personnel. The support plate 9 can be adjusted to a suitable height so that maintenance personnel can more easily approach the components that need to be repaired and improve maintenance efficiency.

[0038] The working principle of the power distribution cabinet with heat dissipation function of this invention is as follows:

[0039] During use, when the internal components of the cabinet body 1 need heat dissipation, the control system activates two fans 5 to begin cooling. The piston of the cylinder 7 moves the fixed bracket 6, causing it to move along with the cabinet body. This movement of the bracket 6 drives the two fans 5 in a linear reciprocating motion. The airflow from the two fans 5 covers different areas of the cabinet body 1, achieving uniform heat dissipation inside the cabinet body 1, improving the cooling effect, preventing localized overheating of the cabinet body 1 that could lead to performance degradation or malfunction of electrical components, and extending the overall lifespan of the electrical components. During the movement of the two fans 5, the two pairs of scrapers 21 fixed to them also move accordingly. Adhering to the surface of filter 4, the fan 5 cleans up dust or foreign objects accumulated on its surface as it moves, preventing filter 4 from becoming clogged and ensuring that air can smoothly pass through filter 4 into the cabinet body 1. This maintains good heat dissipation performance and ensures that the electrical equipment inside the cabinet body 1 operates in a suitable temperature environment. When the fan 5 is operating, the guide plate 20 fixed on its surface can optimize the airflow direction, making the cool air more evenly distributed inside the cabinet body 1, avoiding local overheating or overcooling, and improving the temperature uniformity inside the electrical cabinet. This is beneficial for the electrical equipment to operate in a more stable temperature environment and reduces the risk of equipment performance degradation or failure due to excessive temperature differences.

[0040] Electrical components inside the cabinet body 1 are mounted on the support plate 9. By moving two push rods 14 relative to each other, the fixed connecting plate 12 moves together, compressing two pairs of return springs 18. At this time, the two sets of limit blocks 17 will disengage from the two sets of limit slots 10 opened on the two support frames 3, opening the limit. At this time, the support plate 9 can be disassembled or moved up and down. During the movement of the two connecting plates 12, the stability is ensured by two positioning blocks 13. The required number of support plates 9 are placed according to the number and volume of the installed electronic components, and a reasonable layout is made to make full use of the vertical space of the cabinet body 1 and avoid space waste. In the later maintenance and inspection process, the easily adjustable support plate 9 provides convenience for maintenance personnel. The support plate 9 can be adjusted to a suitable height, so that maintenance personnel can more easily approach the components that need to be repaired, improving maintenance efficiency.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications and substitutions should be covered within the scope of the claims of the present invention.
