Abstract
Description
Technical Field
[0001] This utility model relates to a compact power distribution cabinet. Background Technology
[0002] Existing compact power distribution cabinets typically have their bottom directly in contact with the ground without any raised design. Therefore, they are subject to environmental requirements. If water gets into certain areas, it can affect the operation of the internal components. Although there are bottom vents at the bottom of the cabinet to promote internal heat dissipation, these vents are directly exposed to the external environment and lack filters. Dust and impurities can easily enter the cabinet through these vents, leading to dust accumulation on internal components over time. This affects heat dissipation efficiency and accelerates equipment aging. Improvements and optimizations are needed to address these issues. Utility Model Content
[0003] To address the above problems, the technical problem to be solved by this utility model is to provide a compact power distribution cabinet.
[0004] The technical solution adopted by this compact power distribution cabinet is characterized by including a power distribution cabinet body and a power distribution cabinet raising frame assembly located below the power distribution cabinet body. The power distribution cabinet raising frame assembly includes a raising frame formed by connecting square profiles end to end, height adjustment foot assemblies located at the four corners of the front and rear ends of the raising frame, and a cabinet support assembly located on the raising frame. Each of the four sides of the square profile is provided with a profile limiting groove. The height adjustment foot assembly includes a height adjustment docking block fixed to the outer end of the square profile, a height adjustment screw longitudinally passing through the height adjustment docking block, a support pad fixed to the bottom of the height adjustment screw, and a height adjustment block threadedly connected to the height adjustment screw and located below the height adjustment docking block. The height adjustment block is used to drive the support pad to move up and down. The side of the height adjustment docking block is provided with a height adjustment docking block limiting protrusion that docks with the profile limiting groove.
[0005] The cabinet support assembly includes a support plate, a pull-out plate, and a filter screen placed on the raised frame. The support plate is used to support the bottom of the distribution cabinet and has a support plate baffle at its outer end. The support plate has a heat dissipation hole for communicating with the heat dissipation vent at the bottom of the distribution cabinet. The back of the support plate has a support plate slot for inserting the pull-out plate at the heat dissipation hole. The pull-out plate has a pull-out plate through hole corresponding to the heat dissipation hole. The filter screen is fixed above the pull-out plate.
[0006] The power distribution cabinet raising frame assembly also includes a receiving plate locking assembly. The receiving plate locking assembly includes a locking docking block fixed to the outer end of the square profile and a locking threaded rod transversely passing through the locking docking block. The receiving plate stop is provided with a receiving plate threaded hole that is threadedly connected to the locking threaded rod. The end of the locking threaded rod is provided with a locking rod adjusting handle for easy adjustment. The side of the locking docking block is provided with a locking docking block limiting protrusion that is opposite to the limiting groove of the profile.
[0007] The locking docking block limiting protrusion, the profile limiting groove, and the height adjusting docking block limiting protrusion are all trapezoidal structures.
[0008] The end of the pull-out plate is provided with a pull-out plate stop to facilitate pulling.
[0009] The height adjustment block is provided with wrench insertion holes spaced around an arc to facilitate tool operation.
[0010] The advantages of this compact power distribution cabinet are: the adjustable lifting frame design effectively raises the cabinet body, enhancing environmental adaptability, strong compatibility, and high protection; the pull-out filter assembly ensures heat dissipation at the bottom of the cabinet body while reducing dust and other particles from entering the cabinet and affecting the operation of internal components, and facilitates maintenance.
