Description

Technical Field

[0001] This utility model relates to the field of control cabinet technology, specifically a heat dissipation device for a belt conveyor frequency converter control cabinet. Background Technology

[0002] A frequency converter control cabinet is a device used to control the operation of a motor. It mainly uses a frequency converter to adjust the speed and torque of the motor. During operation, the frequency converter inside the existing frequency converter control cabinet will generate a lot of heat and accumulate inside the control cabinet, so heat dissipation treatment is required inside the control cabinet.

[0003] To overcome the above-mentioned defects, a prior art Chinese patent (publication number: CN213717442U) discloses a heat dissipation control cabinet, which relates to the field of electrical equipment technology. The heat dissipation control cabinet includes a lower cabinet and an upper cabinet, with the upper cabinet placed above the lower cabinet. Air intake components are installed on opposite sides of the lower cabinet, and air exhaust components are installed on opposite sides of the upper cabinet. Ventilation holes are provided at the bottom of the upper cabinet. Airflow from the lower cabinet is guided to the upper cabinet through the ventilation holes. After absorbing heat, the cold airflow diffuses towards the upper cabinet, shortening the path of the hot airflow. The driver in the lower cabinet can be evenly cooled, improving the heat dissipation efficiency of the driver.

[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist during their operation: during the process of air dissipating heat from the electronic components inside the control cabinet, dust from the outside may be brought into the control cabinet, which can easily lead to dust accumulation inside the control cabinet. Utility Model Content

[0005] The purpose of this utility model is to provide a heat dissipation device for a belt conveyor frequency converter control cabinet, so as to solve the problem in the background art that when the air dissipates heat from the electronic components inside the control cabinet, it may bring dust from the outside into the control cabinet, which can easily lead to dust accumulation inside the control cabinet.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation device for a belt conveyor frequency converter control cabinet, comprising a housing, an installation compartment inside the housing, and a door hinged to the front side of the housing;

[0007] The outer shell is equipped with filter structures on both sides, and each side of the outer shell is provided with a recessed mounting groove. A fixing ring is engaged inside the mounting groove, and filter plates are fixedly connected at equal intervals inside the fixing ring.

[0008] Both the upper and lower ends of the rear side of the housing are equipped with limiting structures to fix the cable.

[0009] Preferably, the fixing ring is a frame structure, and the filter plates are evenly distributed inside the fixing ring. The inside and top of the fixing ring are both open structures. A microcontroller is installed inside the outer shell, and a temperature sensor is installed inside the mounting compartment. The temperature sensor and the microcontroller are electrically connected to each other.

[0010] Preferably, the installation chamber has symmetrically distributed air intake windows on both sides, and the air intake windows are aligned with the fixing rings located on both sides of the outer shell. The top and bottom of the installation chamber are fixedly connected to fixing plates, and an installation plate is installed between the two fixing plates.

[0011] Preferably, the top and bottom of the inner side of the installation compartment are provided with openings, and the openings connect the installation compartment and the interior of the outer shell to each other, and the upper and lower outer sides of the outer shell are provided with symmetrically distributed exhaust windows.

[0012] Preferably, axial flow fans are fixedly connected to the top and bottom of the installation compartment, and the axial flow fans are located inside the outer casing. The axial flow fans and the openings at the top and bottom of the installation compartment are aligned with each other, and the axial flow fans and the microcontroller are electrically connected to each other.

[0013] Preferably, the limiting structure includes a reserved hole located on the rear side of the housing, and the reserved hole extends through the housing and the interior of the mounting compartment, and guide rails are fixedly connected inside both reserved holes.

[0014] Preferably, two symmetrically distributed adjusting blocks are slidably connected to the inner sides of the two guide rails, and a limiting frame is fixedly connected to the inner side of the housing. Damping is provided between the adjusting blocks and the guide rails. The limiting frame is located outside the adjusting blocks, and an intercepting plate is fixedly connected between the inner ends of the adjusting blocks and the limiting frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This heat dissipation device for a belt conveyor inverter control cabinet utilizes a real-time monitoring and control mechanism based on temperature sensors and a microcontroller. When the internal temperature of the installation chamber exceeds 45°C, the microcontroller automatically activates the axial flow fan to rapidly expel internal heat while simultaneously introducing clean air that has undergone multiple filtration processes for cooling. Once the temperature drops to a safe range, the axial flow fan automatically stops operating. This intelligent operation based on a temperature-controlled switch not only ensures that electronic components operate at suitable temperatures but also saves energy and reduces unnecessary resource waste.

[0017] Air entering the device from the outside must first pass through multiple layers of filter plates in the fixed ring for multiple filtrations, effectively preventing dust and particulate matter from entering the control cabinet, thereby maintaining the cleanliness of the installation chamber environment, avoiding damage to electronic components from dust accumulation, and extending the service life of the equipment.

[0018] To address the issues of cable securing and sealing, the combined design of the adjusting block, intercepting plate, and limiting frame in the limiting structure can centrally organize the cables and cover excess space in the pre-drilled holes, creating a relatively sealed environment. This sealing protection mechanism effectively prevents foreign objects or dust from entering the device from the cable connection points, further enhancing the protective performance of the control cabinet while ensuring stable operation and equipment cleanliness.

[0026] 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.

[0027] Example 1: Please refer to Figure 1 - Figure 6This utility model provides the following technical solution: a heat dissipation device for a belt conveyor frequency converter control cabinet, including a housing 1, an installation compartment 2 inside the housing 1, and a door 3 hinged to the front of the housing 1; filter structures are installed on both sides of the housing 1, and each side of the housing 1 has a recessed installation groove 4, a fixing ring 5 is engaged inside the installation groove 4, and filter plates 6 are fixedly connected at equal intervals inside the fixing ring 5; limiting structures for fixing cables are provided at the upper and lower ends of the rear side of the housing 1; the fixing ring 5 is a frame structure, and the filter plates 6 are evenly distributed inside the fixing ring 5; the inside and top of the fixing ring 5 are open structures; a microcontroller is installed inside the housing 1, and a temperature sensor is installed inside the installation compartment 2. The temperature sensor and the microcontroller are electrically connected to each other; the two sides of the installation chamber 2 are provided with symmetrically distributed air intake windows 7, and the air intake windows 7 are aligned with the fixing rings 5 ​​located on both sides of the outer shell 1; the top and bottom of the inner side of the installation chamber 2 are fixedly connected with fixing plates 11, and the two fixing plates 11 are installed between the two fixing plates 11; the top and bottom of the inner side of the installation chamber 2 are provided with openings, and the openings connect the installation chamber 2 and the interior of the outer shell 1; the upper and lower outer sides of the outer shell 1 are provided with symmetrically distributed exhaust windows 8; the top and bottom of the installation chamber 2 are fixedly connected with axial flow fans 9, and the axial flow fans 9 are located inside the outer shell 1; the axial flow fans 9 are aligned with the openings at the top and bottom of the installation chamber 2, and the axial flow fans 9 are electrically connected to each other.

[0028] The mounting plate 12 is installed inside the fixing plate 11 at both the top and bottom ends, through... Figure 4 It can be seen that the fixed plate 11 has a hollow structure inside, and the fixed plate 11 has equidistantly distributed horizontal bars fixedly connected inside. The upper and lower ends of the mounting plate 12 form annular sleeves that are slidably connected to the outside of the horizontal bars. The connection between the mounting plate 12 and the fixed plate 11 is provided with damping. First, electronic components such as switches and frequency converters are installed on the horizontally distributed mounting rods inside the mounting plate 12. The position of the electronic components installed on the mounting plate 12 is adjusted by sliding the mounting plate 12 between the two fixed plates 11. During the installation and maintenance process, the mounting plate 12 is slid to the side closest to the door 3, which facilitates the installation and maintenance of electronic components.

[0029] After installation, the electronic components are interconnected with the outside world via cables. These cables extend to the outside through pre-drilled holes 10. During operation inside the installation chamber 2, the electronic components generate heat, which heats the interior of the chamber. A temperature sensor inside the installation chamber 2 monitors the temperature in real time. When the temperature exceeds 45°C, the temperature sensor transmits the data to the microcontroller, which then controls the axial flow fan 9 to start. During operation, the axial flow fan 9... Axial flow fan 9 simultaneously draws air from the top and bottom of the mounting chamber 2. The external air is filtered by the filter plate 6 inside the fixing ring 5 before entering the mounting chamber 2. At the same time, the hot air drawn out by the axial flow fan 9 is discharged from the outer casing 1 and the mounting chamber 2 through the exhaust window 8, thereby dissipating heat from the electronic components installed inside the mounting chamber 2. When the internal temperature of the mounting chamber 2 drops below 45°C, the microcontroller will stop the cavity axial flow fan 9. A temperature control switch is formed by the temperature sensor and the microcontroller to control the start and stop of the axial flow fan 9 in real time, reducing resource waste.

[0030] After the air passes through the fixing ring 5 and the filter plate 6, the air will be filtered multiple times by multiple filter plates 6 as it passes through the fixing ring 5, thus ensuring the cleanliness of the air entering the installation chamber 2. Since the top and bottom of the fixing ring 5 are designed as open structures, when it is necessary to clean the filter plate 6, the fixing ring 5 is first removed from the installation groove 4, and water is injected into the fixing ring 5 from the top to rinse the multiple filter plates 6. The rinsing water will be discharged from the bottom of the fixing ring 5.

[0031] Example 2: Based on Example 1, a limiting structure is also disclosed, the specific structure of which is as follows: The limiting structure includes a reserved hole 10 located on the rear side of the outer shell 1, and the reserved hole 10 penetrates the interior of the outer shell 1 and the mounting compartment 2, and guide rails 13 are fixedly connected inside the two reserved holes 10; two symmetrically distributed adjusting blocks 14 are slidably connected to the inner side of the two guide rails 13, and a limiting frame 15 is fixedly connected to the inner side of the outer shell 1, and damping is provided between the adjusting block 14 and the guide rail 13; the limiting frame 15 is located outside the adjusting block 14, and an intercepting piece 16 is fixedly connected between the inner end of the adjusting block 14 and the limiting frame 15.

[0032] The cables of the electronic components installed inside the installation compartment 2 will extend to the outside through the two guide rails 13 installed inside the reserved hole 10. At the same time, the cables will be located between the two adjusting blocks 14. At this time, the two adjusting blocks 14 are pulled closer to each other until the two adjusting blocks 14 gather and fix the cables in the middle together. Simultaneously, the adjusting blocks 14 will drive the intercepting plate 16 to extend between the inner end of the limiting frame 15 and the adjusting block 14, thereby covering the excess space of the reserved hole 10, ensuring the basic sealing environment of the outer shell 1 and the interior of the installation compartment 2, and preventing foreign objects from entering the interior.
