Description

Technical Field

[0001] The utility model relates to the technical field of electric power, in particular to a distribution box. Background Art

[0002] Distribution boxes are characterized by their small size, easy installation, exceptional technical performance, fixed location, unique configuration features, and unrestricted site availability. They are widely used, stable and reliable, highly space-efficient, and environmentally friendly. They serve as the control center for the rational distribution of power to various components in the power supply line. They are the link that reliably receives power from upstream sources and accurately feeds power to loads, and are crucial for ensuring user satisfaction with power quality.

[0003] If the ventilation holes on traditional distribution boxes are only equipped with simple dust-proof structures, they are prone to clogging due to dust accumulation, reducing ventilation efficiency. If dust-proof measures are reduced to ensure ventilation, more dust will enter the box, affecting the life of electrical components. In addition, the ventilation holes of traditional distribution boxes cannot adjust the ventilation volume according to actual needs, which may result in insufficient or excessive heat dissipation, which is not conducive to stable operation of the equipment and energy consumption control. Utility Model Content

[0004] The purpose of the utility model is to propose a distribution box in order to solve the problems that the ventilation openings of the existing distribution box are easily blocked by dust accumulation, thereby reducing the ventilation efficiency and the ventilation volume cannot be flexibly adjusted.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technology: a distribution box, including a box body, a box door is provided on the box body through a hinge, and a ceiling is provided on the top of the box body, electrical components are provided inside the box body through a bracket, a ventilation mechanism that can self-clean and adjust the ventilation volume is provided at the ventilation port position of the box body, and a heat dissipation mechanism that can assist in heat dissipation is also provided inside the box body.

[0006] As a further description of the above technical solution: the ventilation mechanism includes a frame detachably mounted on the box body by screws, and a dustproof net is provided in the frame;

[0007] The dust screen is detachably mounted on the frame through the cooperation of the positioning plate and the positioning bolts.

[0008] As a further description of the above technical solution: the frame is provided with a cleaning component capable of utilizing natural wind to clean the dust screen;

[0009] The cleaning component includes a mounting base rotatably mounted on the frame through a connecting shaft, a fan blade located below the frame is provided at the bottom of the mounting base, and a brush rod in contact with the dustproof net is provided at the top of the mounting base.

[0010] As a further description of the above technical solution: a threaded end is provided at the bottom of the brush rod, and a connecting screw hole matching the threaded end is provided on the mounting seat.

[0011] As a further description of the above technical solution: the ventilation mechanism also includes a partition slidably mounted on the frame, and the partition is provided with through holes corresponding to the ventilation holes of the box body.

[0012] As a further description of the above technical solution: a limiting bolt is provided at the bottom of the frame through a bolt seat, and the end of the limiting bolt can abut against the partition.

[0013] As a further description of the above technical solution: the heat dissipation mechanism includes a heat dissipation fan and a temperature sensor arranged in the box body, and the heat dissipation fan is turned on and off by a controller according to a temperature signal from the temperature sensor.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0015] By utilizing the natural wind cleaning component, the dust screen can be automatically cleaned under the action of natural wind, preventing dust from clogging the mesh holes over a long period of time, maintaining the ventilation channel unobstructed, eliminating the need for frequent manual cleaning and reducing maintenance costs;

[0016] By adjusting the actual opening area of ​​the vents, the ventilation volume can be flexibly controlled. When the equipment load in the distribution box is high and the temperature rises, the ventilation volume can be increased to accelerate heat dissipation. When the ambient temperature is low or the equipment is running at low load, the ventilation volume can be reduced to avoid the low temperature in the box affecting the equipment operation, thus achieving a balance between energy saving and stable operation.

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figures 1-6 A distribution box provided in this embodiment includes a box body 1, a box door 2 is provided on the box body 1 through a hinge, and a ceiling 3 is provided on the top of the box body 1, electrical components 5 are provided inside the box body 1 through a bracket 4, and a ventilation mechanism 6 that can self-clean and adjust the ventilation volume is provided at the ventilation port position of the box body 1.

[0027] In the present invention, the box body 1 serves as the core bearing structure, and the box door 2 connected by the hinge can be flexibly opened and closed. When the box door 2 is closed, it can effectively prevent the invasion of external dust, water vapor and foreign objects, thereby ensuring the safety of internal equipment. The electrical components 5 (such as circuit breakers, electricity meters, relays, etc.) installed by the bracket 4 in the box body 1 realize power distribution, control and protection. A ventilation hole is opened on the box body 1, and a ventilation mechanism 6 arranged on the outside of the ventilation hole prevents external dust and other impurities from entering the box body 1 while ensuring ventilation and heat dissipation of the ventilation hole, thereby protecting the electrical components 5 from dust accumulation.

[0028] Specifically, the ventilation mechanism 6 includes a frame 61 detachably mounted on the box body 1 by screws, and a dustproof net 62 is provided in the frame 61;

[0029] The dust screen 62 is detachably mounted on the frame 61 through the cooperation between the positioning plate 611 and the positioning bolts 621 .

[0030] Among them, the frame 61 serves as the core supporting component and is detachably installed at the vent position of the box body 1 by screws, which not only ensures the firm fit between the frame 61 and the box body 1, but also provides a basis for the subsequent overall disassembly and maintenance of the frame 61. The dustproof net 62 can effectively intercept dust, sand, fiber and other impurities in the outside air through its fine mesh structure, and prevent these pollutants from entering the interior through the vent of the box body 1. The dustproof net 62 is detachable by tightening and loosening the positioning bolts 621, which makes it easy to remove the dustproof net 62 separately for deep cleaning or replacement.

[0031] Specifically, such as Figure 2 and Figure 5 As shown, a cleaning assembly 63 capable of utilizing natural wind to clean the dust screen 62 is provided on the frame 61;

[0032] The cleaning assembly 63 includes a mounting base 631 rotatably mounted on the frame 61 via a connecting shaft 634 , a fan blade 632 located below the frame 61 is provided at the bottom of the mounting base 631 , and a brush rod 633 in contact with the dustproof net 62 is provided at the top of the mounting base 631 .

[0033] Among them, when there is natural wind flowing from the outside, the fan blades 632 under the frame 61 rotate under the action of the wind. The fan blades 632 are fixedly connected to the mounting base 631. Therefore, the rotation of the fan blades 632 will drive the mounting base 631 to rotate synchronously on the frame 61 around the connecting shaft 634. The brush rod 633 on the top of the mounting base 631 maintains contact with the dustproof net 62. As the mounting base 631 rotates, the brush rod 633 will perform a circular or reciprocating wiping motion along the surface of the dustproof net 62, thereby cleaning the dust and debris attached to the dustproof net 62. No additional power drive is required. Only natural wind can drive the brush rod 633 to automatically clean the dustproof net 62, which can timely remove dust accumulated on the surface of the dustproof net 62 and prevent dust from clogging the mesh holes for a long time.

[0034] It should be noted that the bottom of the brush rod 633 is provided with a threaded end 635, and the mounting base 631 is provided with a connecting screw hole 636 that mates with the threaded end 635. If the bristles of the brush rod 633 become worn, deformed, or the cleaning effect decreases due to long-term use, the brush rod 633 can be quickly replaced with a new one by simply rotating the brush rod 633 to unscrew the threaded end 635 from the connecting screw hole 636, without having to disassemble the entire mounting base 631. This greatly simplifies the component replacement process and reduces maintenance time and workload.

[0035] Specifically, such as Figure 4 As shown, the ventilation mechanism 6 also includes a partition 64 slidably mounted on the frame 61, and a through hole 641 corresponding to the ventilation opening of the box body 1 is opened on the partition 64. A limiting bolt 66 is set at the bottom of the frame 61 through a bolt seat 65, and the end of the limiting bolt 66 can abut against the partition 64.

[0036] When the ventilation volume needs to be adjusted, push the partition 64 to slide along the frame 61, and the through hole 641 will be misaligned with the ventilation port of the box body 1. The greater the degree of misalignment, the smaller the actual ventilation area. Conversely, the smaller the degree of misalignment, the larger the ventilation area. After the adjustment is completed, tighten the limiting bolt 66 on the bolt seat 65 at the bottom of the frame 61 so that its end abuts against the partition 64, and use friction to fix the partition 64 in the current position to prevent it from sliding by itself under the ventilation airflow or external vibration. By sliding the partition 64 to change the degree of misalignment between the through hole 641 and the ventilation port of the box body 1, the actual opening area of ​​the ventilation port can be flexibly controlled to meet the heat dissipation requirements of the electrical components 5 inside the box body 1 under different operating loads and ambient temperatures, and avoid overheating due to insufficient ventilation or energy waste caused by excessive ventilation.

[0037] Specifically, such as Figure 1 and Figure 6 As shown, a heat dissipation mechanism 7 is provided inside the box 1 to assist in heat dissipation. The heat dissipation mechanism 7 includes a heat dissipation fan 71 and a temperature sensor 73 provided inside the box 1. The heat dissipation fan 71 is turned on and off by a controller 72 according to a temperature signal from the temperature sensor 73.

[0038] The temperature sensor 73 is installed inside the box 1, monitors the ambient temperature inside the box 1 in real time, and continuously transmits the temperature signal to the controller 72. The controller 72 presets a temperature threshold. When the received temperature signal shows that the temperature inside the box 1 reaches or exceeds the threshold, the controller 72 issues a start command to control the cooling fan 71 to turn on, thereby accelerating the air circulation inside the box 1. When the temperature sensor 73 detects that the temperature inside the box 1 drops below the threshold, the temperature signal is fed back to the controller 72, and the controller 72 issues a shutdown command to stop the cooling fan 71.

[0039] It should be noted that the preset temperature threshold of controller 72 is set in the range of 30℃~40℃ (for example, it is set to 35℃ to start the cooling fan and 30℃ to shut it down). The specific value can be flexibly adjusted by controller 72 to adapt to the cooling requirements in different environments. The temperature sensor 73 uses a digital temperature sensor of model DS18B20, which supports a measurement range of -55℃~125℃ and has high accuracy. The controller 72 adopts a control structure with a single-chip microcomputer as the core.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
