Description

Technical Field

[0001] This utility model belongs to the field of distribution box technology, specifically a distribution box with a dustproof and dehumidifying structure. Background Technology

[0002] As a key device in the power system for distributing, controlling and protecting electrical energy, the distribution box is widely used in many fields such as industrial production, building construction, municipal engineering and transportation facilities. It integrates precision electrical components such as circuit breakers, relays and contactors. The normal operation of these components is directly related to the stability and safety of the power system.

[0003] In practical applications, simple grilles or filters are often used to protect the inside of distribution boxes. However, these cannot completely block fine dust, and moisture can still directly enter the distribution box. Although some sealed distribution boxes can reduce dust intrusion, they can lead to poor internal heat dissipation, which in turn exacerbates the problem of overheating of components. Summary of the Invention

[0004] To overcome the above-mentioned defects, this utility model provides a distribution box with a dustproof and dehumidifying structure, which solves the problem that using simple grilles or filters to protect the inside of the distribution box cannot completely block fine dust, and moisture can still directly enter the inside of the distribution box. Although some sealed distribution boxes can reduce dust intrusion, they will lead to poor internal heat dissipation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a distribution box with a dustproof and dehumidifying structure, comprising a box body, a top cover fixedly connected to the top of the box body, a central hole at the bottom of the top cover communicating with the top of the box body, several air inlets at the front and rear sides of the bottom of the top cover, moisture-absorbing cotton inside the top cover located at the opening at the top of the box body, an air guide assembly below the central hole, exhaust assemblies fixed on both sides of the air guide assembly, the air guide assembly including an air box, an air trough inside the air box located in the middle below the central hole, several air outlets on both sides of the air box communicating with the air trough, the exhaust assembly including a baffle, two ends of the baffle fixed to one side of the air box, the side of the baffle away from the air box fixed to the inner side wall of the box body, an air duct on the side of the air box near the inner wall of the box body, and several exhaust holes communicating with the air duct in the air box.

[0006] As a further embodiment of this utility model: the baffle is U-shaped, and the top of the baffle is tilted towards the opening of the air duct.

[0007] As a further embodiment of this utility model: the opening at the bottom of the air duct is connected to the bottom of the box, and an exhaust fan is installed at the bottom of the box. Several exhaust pipes are connected to the air inlet ends on both sides of the exhaust fan, and the exhaust pipes are connected to the opening at the bottom of the air duct.

[0008] As a further embodiment of this utility model: an inspection door is installed on the lower part of the front of the housing, and the inspection door has several heat dissipation vents that are connected to the air outlet of the exhaust fan.

[0009] As a further embodiment of this utility model: a sealing door is installed on the front of the box, the maintenance door is fixed to the lower part of the front of the box by bolts, and a cover is provided on the front of the maintenance door above the heat dissipation vent.

[0010] As a further embodiment of this utility model: a number of partitions are provided between the baffle and the air box, with two partitions in each group, and a mounting plate is inserted between the corresponding two partitions.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This distribution box, equipped with a dustproof and dehumidifying structure, allows air to enter the top cover through an air inlet at the bottom of the cover, where it comes into contact with absorbent cotton. The absorbent cotton filters impurities and removes moisture from the air. The air inlet is located below the top cover to prevent impurities or water from falling into it. Air passes through the absorbent cotton and enters the air channel within the air box through the central hole. The air in the air channel then exits through several air outlets on both sides. Because the electrical components on the mounting plate are located between the air box and the baffle, the air exiting the outlets blows directly onto the electrical components, carrying away heat. The air then exits through the exhaust vents into the ductwork. Combined with the use of an exhaust fan, the exhaust duct carries away the extracted hot air. This active cooling method improves the airflow within the box. The absorbent cotton effectively blocks dust and moisture, enhancing the protection of the electrical components inside the box. Furthermore, the air blows directly onto the electrical components, and the hot airflow is quickly expelled from the exhaust vents, providing targeted and rapid heat removal from the electrical components, thus improving the overall cooling effect.

[0013] This distribution box, equipped with a dustproof and dehumidifying structure, allows the mounting plate to slide between two opposing partitions by pulling it forward until it is completely detached from the partitions. After inserting the mounting plate into the upper or lower sets of partitions, the partitions can support and limit the mounting plate, enabling adjustment of the distance between two adjacent mounting plates on the same side. This facilitates the installation of electrical components of different specifications, making the distribution box highly versatile.

[0014] This distribution box, equipped with a dustproof and dehumidifying structure, uses an exhaust pipe to blow extracted hot air through the exhaust fan's outlet toward the maintenance door, where it is expelled from the box through the heat dissipation vents. This achieves the purpose of quickly removing heat from the box. Furthermore, the baffles on the heat dissipation vents effectively prevent dust and impurities from entering the box. When maintaining the exhaust fan or cleaning the heat dissipation vents, the maintenance door can be detached from the box by loosening the bolts on both sides of the maintenance door, making it easy to clear any blockages in the heat dissipation vents. The exhaust fan will also be exposed, making it easy to remove for maintenance. Attached Figure Description

Detailed Implementation

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] like Figures 1-6 As shown, this utility model provides a technical solution: a power distribution box with a dustproof and dehumidifying structure, including a box body 1, a top cover 5 fixedly connected to the top of the box body 1, a central hole 6 opened at the bottom of the top cover 5, the central hole 6 communicating with the top of the box body 1, a plurality of air inlets 7 opened on the front and rear sides of the bottom of the top cover 5, a moisture-absorbing cotton 8 provided inside the top cover 5, the moisture-absorbing cotton 8 being located at the opening at the top of the box body 1, the moisture-absorbing cotton 8 being able to filter impurities and remove moisture from the gas, and the air inlets 7 being located below the top cover 5 to prevent impurities or water stains from falling into the air inlets 7;

[0024] Below the central hole 6, there is a guide air assembly 9. On both sides of the guide air assembly 9, there are exhaust air assemblies 10. The guide air assembly 9 includes an air box 901. An air channel 902 is opened inside the air box 901. The air channel 902 is located in the middle below the central hole 6. Several air outlets 903 are opened on both sides of the air box 901, and the air outlets 903 are connected to the air channel 902. The exhaust air assembly 10 includes a baffle 101. The baffle 101 has a U-shaped design, and the top of the baffle 101 is inclined towards the opening of the air channel 902, which can guide the gas flow and improve the stability of the gas flow.

[0025] Several sets of partitions 11 are provided between the baffle 101 and the air box 901. Each set of partitions 11 consists of two partitions. A mounting plate 12 is inserted between the two corresponding partitions 11. By installing electrical components on multiple mounting plates 12 inside the housing 1, the electrical components can be arranged in layers. By pulling the mounting plate 12 forward, the mounting plate 12 can be removed from the partition 11 at the current position and then inserted into the two sets of partitions 11 above or below, thereby changing the spacing between two adjacent mounting plates 12 on the same side, which facilitates the installation of electrical components of different specifications.

[0026] The two ends of the side of the baffle 101 are fixed to one side of the air box 901. The side of the baffle 101 away from the air box 901 is fixed to the inner side wall of the box 1. The side of the air box 901 near the inner wall of the box 1 has an air duct 102. The opening at the bottom of the air duct 102 is connected to the bottom of the box 1. An exhaust fan 13 is installed at the bottom of the box 1. Several exhaust pipes 14 are connected to the air inlet ends on both sides of the exhaust fan 13. The exhaust pipes 14 are connected to the opening at the bottom of the air duct 102. When the exhaust fan 13 is started, the exhaust pipes 14 on both sides of the exhaust fan 13 draw gas from the bottom of the air duct 102. The exhaust pipes 14 blow the drawn hot gas through the air outlet end of the exhaust fan 13 toward the inspection door 3 and discharge it from the heat dissipation port 4. By actively dissipating heat, the air flow inside the box 1 is improved, and the heat inside the box 1 can be quickly removed.

[0027] A maintenance door 3 is installed on the lower front of the housing 1. Several heat dissipation vents 4 are provided in the maintenance door 3 and are connected to the air outlet of the exhaust fan 13.

[0028] A sealing door 2 is installed on the front of the enclosure 1. The maintenance door 3 is fixed to the lower part of the front of the enclosure 1 by bolts. By loosening the bolts on both sides of the maintenance door 3, the maintenance door 3 is detached from the enclosure 1, so that the heat dissipation vent 4 can be cleared. The exhaust fan 13 will be exposed so that it can be removed for maintenance. A baffle is provided on the front of the maintenance door 3 above the heat dissipation vent 4. The baffle on the heat dissipation vent 4 will effectively prevent dust and impurities from entering the enclosure 1.

[0029] The air box 901 has several exhaust holes 103 that are connected to the air duct 102.

[0030] The working principle of this utility model is as follows:

[0031] When in use, open the sealed door 2 on the front of the box 1, install the electrical components on the multiple mounting plates 12 inside the box 1, and close the sealed door 2. Heat will be generated inside the box 1 due to the operation of the electrical components. By starting the exhaust fan 13, the exhaust pipes 14 on both sides of the exhaust fan 13 will draw gas from the bottom of the air duct 102, so that the gas outside the box 1 enters the top cover 5 through the air inlet 7 at the bottom of the top cover 5 and comes into contact with the moisture-absorbing cotton 8. The moisture-absorbing cotton 8 can filter impurities and remove moisture from the gas.

[0032] Secondly, the gas passes through the absorbent cotton 8 and enters the air channel 902 in the air box 901 through the central hole 6. Since the top of the baffle 101 is tilted towards the opening of the air channel 902, it can guide the gas flow and improve the stability of the gas flow. Secondly, the gas in the air channel 902 will be discharged from several air outlets 903 on both sides. Since the electrical components on the mounting plate 12 are located between the air box 901 and the baffle 101, the gas discharged from the air outlets 903 can blow towards the electrical components, and after taking away the heat in the electrical components, the gas is introduced into the air duct 102 from the exhaust hole 103. With the use of the exhaust fan 13, the exhaust pipe 14 blows the extracted hot gas through the exhaust end of the exhaust fan 13 towards the inspection door 3, that is, it is discharged from the heat dissipation port 4 of the housing 1.

[0033] When maintaining the exhaust fan 13 or cleaning the heat dissipation vent 4, the maintenance door 3 is detached from the housing 1 by loosening the bolts on both sides of the maintenance door 3, so that the heat dissipation vent 4 can be cleared. The exhaust fan 13 will be exposed, so that it can be taken out for maintenance. When adjusting the distance between the two mounting plates 12 on the same side, the mounting plate 12 is pulled forward so that it can slide between the two opposing partitions 11 until the mounting plate 12 is completely detached from the partitions 11. After the mounting plate 12 is inserted into the two sets of partitions 11 above or below, the partitions 11 can support and limit the mounting plate 12, so as to achieve the purpose of adjusting the distance between the two adjacent mounting plates 12 on the same side.
