Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits.

DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Example
[0027] like Figure 1 and Figure 4As shown, the utility model provides a technical solution: a moisture-proof low-voltage distribution cabinet, including a base 10, a distribution cabinet 11 is fixedly installed on the upper end surface of the base 10, a door body 12 is hinged on one side of the distribution cabinet 11, a handle 13 is fixedly connected to the outer wall of the door body 12, heat dissipation holes 14 are opened on the two opposite side walls in the middle of the distribution cabinet 11, and a protective mechanism for shielding rain is arranged on the two opposite side walls of the top of the distribution cabinet 11. A moisture-proof component for absorbing humid air is arranged on the top of the distribution cabinet 11. During specific use, the base 10 of the distribution cabinet is designed to ensure its stability and load-bearing capacity. The door body 12 on one side of the distribution cabinet 11 is hinged, which is easy to open and close, and convenient for maintenance and maintenance of internal equipment. During maintenance, the heat dissipation holes 14 on the power distribution cabinet 11 effectively solve the problem of heat generated by the equipment during operation. The design of these heat dissipation holes 14 allows the heat to be discharged smoothly to prevent the equipment from being damaged due to overheating. At the same time, it also ensures that the temperature inside the power distribution cabinet 11 is moderate, extending the service life of the equipment. The power distribution cabinet 11 is provided with a rainproof protection mechanism, which can effectively prevent rain from entering the power distribution cabinet 11, thereby ensuring the normal operation of the equipment. This design is suitable for outdoor or humid environments, and enhances the adaptability and durability of the power distribution cabinet 11. The moisture-proof component arranged on the top of the power distribution cabinet 11 can absorb humid air, reduce the humidity inside the power distribution cabinet 11, and prevent the equipment from being damaged due to moisture.
[0028] As an implementation method in this embodiment, Figure 1 and Figure 2As shown, the protective mechanism includes a mounting plate 20 fixedly mounted on the outer wall of the distribution cabinet 11, a slide groove 21 is provided on the inner bottom wall of the mounting plate 20, a slide plate 22 is slidably connected in the slide groove 21, the cross section of the slide groove 21 is a T-shaped structure, and the cross section of the slide plate 22 is a T-shaped structure. Since the T-shaped structure has a large contact area and a stable support point, the slide groove 21 and the slide plate 22 can maintain a stable sliding state when used in conjunction with each other, and are not prone to shaking or deviation. A protective plate 23 is fixedly connected to the lower end surface of the slide plate 22, a rack 24 is fixedly connected to the bottom side wall of the slide plate 22, a mounting frame 25 is fixedly mounted on one side of the upper end surface of the mounting plate 20, a servo motor 28 is fixedly mounted on the mounting frame 25, and a drive shaft 26 is fixedly connected to the output end of the servo motor 28, the bottom end of the drive shaft 26 vertically downward passes through the mounting plate 20 and the end is fixedly sleeved with a drive gear 27 The driving gear 27 is meshed with the rack 24 for transmission, and the driving shaft 26 is rotatably connected to the mounting plate 20 through a bearing. During specific use, the servo motor 28 is used to drive the driving gear 27 on the driving shaft 26 to rotate, so that the driving gear 27 drives the rack 24 to move, and the slide plate 22 fixedly connected to the rack 24 moves synchronously, so that the slide plate 22 drives the protective plate 23 to block the heat dissipation holes 14. When the heat dissipation holes 14 need to be blocked, the servo motor 28 drives the protective plate 23 to move toward the distribution cabinet 11 until the heat dissipation holes 14 are completely blocked. When the heat dissipation holes 14 need to be exposed for heat dissipation, the servo motor 28 drives the protective plate 23 away from the distribution cabinet 11. This design can not only flexibly adjust the opening degree of the heat dissipation holes 14 as needed, but also effectively prevent external dust and debris from entering the inside of the distribution cabinet 11 when heat dissipation is not needed.
[0029] As an implementation method in this embodiment, Figure 4 As shown, the moisture-proof component includes an L-shaped storage plate 30 symmetrically fixed on the top wall of the distribution cabinet 11, and a storage frame 31 for storing desiccant is placed on the two L-shaped storage plates 30. A plurality of vent holes 32 are arranged in an array on the bottom wall of the storage frame 31. During specific use, the storage frame 31 is supported by the set L-shaped storage plate 30, so that the storage frame 31 can be placed on the two L-shaped storage plates 30, and the desiccant stored in the storage frame 31 absorbs moisture in the air.
[0030] As an implementation method in this embodiment, Figure 2 and Figure 3As shown, a plurality of accommodating cavities 40 are arranged in an array on the inner bottom wall of the slide groove 21. The accommodating cavities 40 are hemispherical structures. Balls 41 are arranged in the accommodating cavities 40. The balls 41 roll freely in the accommodating cavities 40. The lower end surface of the slide plate 22 contacts the rolling surface of the balls 41. During specific use, the slide plate 22 is mounted on the balls 41 to reduce the friction between the slide plate 22 and the slide groove 21, so that the slide plate 22 can be translated more smoothly through the balls 41.
[0031] As an implementation method in this embodiment, Figure 1 As shown, a protective frame 281 is provided on the outer fixed sleeve of the servo motor 28, and the outer wall of the protective frame 281 is coated with waterproof coating. The servo motor 28 is protected by the protective frame 281. The waterproof coating has excellent waterproof performance and can resist moisture erosion for a long time. Even in a humid or rainy environment, the waterproof function of the coating can ensure that the protective frame 281 remains dry, thereby further enhancing its protective effect on the servo motor 28.
[0032] As an implementation method in this embodiment, Figure 1 and Figure 2 As shown, a groove 231 is provided on the side wall of the protective plate 23 close to the distribution cabinet 11. The groove 231 can expand the distance between the protective plate 23 and the heat dissipation hole 14. The increase in the distance makes the air flow between the inside and outside of the distribution cabinet 11 smoother, reducing the possibility of air flow obstruction. The heat inside the distribution cabinet 11 can be discharged more efficiently through the heat dissipation hole 14, reducing the risk of equipment damage due to overheating.
[0033] Working principle: When in use, the servo motor 28 is set to drive the driving gear 27 on the driving shaft 26 to rotate, so that the driving gear 27 drives the rack 24 to move, and the skateboard 22 fixedly connected to the rack 24 moves synchronously, so that the skateboard 22 drives the protective plate 23 to block the heat dissipation holes 14. When the heat dissipation holes 14 need to be blocked, the servo motor 28 drives the protective plate 23 to move closer to the distribution cabinet 11 until the heat dissipation holes 14 are completely blocked. When the heat dissipation holes 14 need to be exposed for heat dissipation, the servo motor 28 drives the protective plate 23 away from the distribution cabinet 11. This design can not only flexibly adjust the opening degree of the heat dissipation holes 14 as needed, but also effectively prevent external dust and debris from entering the inside of the distribution cabinet 11 when heat dissipation is not needed, and the moisture remaining on the inside of the distribution cabinet 11 is absorbed by the desiccant stored in the storage frame 31.
[0034] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
