Description

Technical Field

[0001] The utility model belongs to the technical field of low-voltage cabinets, in particular to a moisture-proof low-voltage cabinet. Background Art

[0002] Low-voltage cabinets, also known as low-voltage switchgear, are suitable for power transmission, distribution, and conversion in various businesses, factories, and public services requiring high energy consumption. Low-voltage distribution cabinets are rated for AC 50Hz, 380V, and are used for power conversion and control in power, lighting, and distribution systems. These cabinets feature strong breaking capacity, excellent dynamic thermal stability, flexible electrical solutions, easy assembly, a wide range of systems, strong practicality, and a novel structure.

[0003] Existing low-voltage cabinets are installed in different locations, but most of them are outdoors or exposed to working environments. Therefore, heat dissipation and moisture-proofing are more important. When rainwater accidentally enters the cabinet on rainy days, it is easy for the electrical components inside the cabinet to short-circuit due to moisture. Generally, the ventilation holes of the cabinet are equipped with filter plates to prevent dust from entering. However, after long-term use, the filter plates are easily clogged, resulting in poor ventilation and reduced heat dissipation effects. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a moisture-proof low-voltage cabinet. The gear roller on the surface of the rack drives the brush cylinder to rotate to clean the filter plate to prevent dust from clogging the filter plate and causing poor ventilation. Through the setting of the rain shield, rainwater can be prevented from entering the interior of the cabinet when it rains. Through the setting of the splash guard, rainwater splashing on the rain shield can be blocked, thereby preventing the electrical components from getting damp after rainwater enters the cabinet.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a moisture-proof low-voltage cabinet, comprising a cabinet body, the front end of the cabinet body being movably connected to a cabinet door, the rear end of the cabinet body being provided with a heat dissipation hole, ventilation holes being respectively provided on both sides of the cabinet body, filter plates being fixedly connected inside the ventilation holes, fixed frames being respectively fixedly connected on both sides of the cabinet body, multiple rain shields being fixedly connected inside the fixed frames, splash guards being fixedly connected on the surfaces of the rain shields, electric slide rails being respectively fixedly connected on both sides of the interior of the cabinet body, sliders being slidably connected inside the electric slide rails, fixed columns being fixedly connected on the surfaces of the sliders, brush cylinders being rotatably connected at one end of the fixed columns away from the sliders, gears being fixedly connected at one end of the brush cylinders away from the fixed columns, racks being respectively fixedly connected on both sides of the interior of the cabinet body, a hollow box being fixedly connected at the lower interior of the cabinet body, and a heat dissipation fan being provided inside the heat dissipation holes.

[0006] Furthermore, the surface of the gear is engaged with the surface of the rack, and the rack is located above the ventilation hole.

[0007] Furthermore, a motor is fixedly connected to the rear side of the cabinet, and an output shaft of the motor is fixedly connected to a baffle.

[0008] Compared with the prior art, the beneficial effects of the present invention are:

[0009] 1. When it is necessary to clean the dust on the filter plate, the electric slide rail can be started to drive the slider to slide, the slider drives the fixed column to move, the fixed column drives the brush cylinder to move, the brush cylinder drives the gear to move, and the gear drives the brush cylinder on the surface of the rack to rotate to clean the filter plate to prevent dust from clogging the filter plate and causing poor ventilation. The setting of the rain shield can prevent rainwater from entering the interior of the cabinet when it rains. The setting of the splash guard can block rainwater splashing on the rain shield, thereby preventing rainwater from entering the cabinet and causing moisture to the electrical components.

[0010] 2. Through the setting of the hollow box, moisture-proof items such as lime bags can be placed inside the hollow box. In order to prevent rainwater from entering the cabinet through the heat dissipation holes, the motor can be started to drive the baffle to rotate, and the heat dissipation holes can be covered by the baffle.
