Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment, and specifically relates to a circulating drying device inside an electrical control cabinet. Background Technology

[0002] An electrical control cabinet is a cabinet-like device used for the centralized installation, protection, and control of various electrical components (such as circuit breakers, relays, contactors, PLC modules, and instruments). In some electrical control cabinets, when faced with humid environments, the lack of an internal circulation drying device can lead to a series of problems. For example, in high-humidity environments, moisture in the air easily accumulates inside the cabinet. Over time, the surfaces of electrical components absorb moisture, causing a decrease in their insulation performance and potentially leading to short-circuit faults. This is mainly because the cabinet is usually not completely sealed, allowing humid air from the outside to easily enter, and the poor air circulation inside the cabinet prevents the timely dissipation of moisture. To address this, the conventional approach is to create ventilation holes in the cabinet, hoping to reduce humidity through natural air convection. However, while ventilation holes can promote air exchange, they are difficult to control humidity precisely. In dusty environments, a large amount of dust will enter with the air and adhere to electrical components. This not only affects the heat dissipation of the components, but may also further aggravate the damage caused by moisture due to the dust adsorbing moisture. At the same time, it increases the risk of component wear and short circuits, ultimately affecting the stable operation and service life of the electrical control cabinet. Therefore, a new structure is needed to solve the above technical problems. Utility Model Content

[0011] In a preferred embodiment, a humidity sensor for detecting the humidity inside the box body is installed at the center of the right inner wall of the box body. The humidity sensor and the drying component are electrically connected to the touch screen display via wires.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are: 1.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 4 As the first embodiment of this utility model: an internal circulating drying device for an electrical control cabinet, comprising: a cabinet assembly and a drying assembly, wherein the cabinet assembly is equipped with a drying assembly for adsorbing and drying the air inside the cabinet assembly, the cabinet assembly includes a cabinet body 100 for installing electrical modules, and a cabinet cover 120 is dampedly hinged to the upper surface of the cabinet body 100 via a hinge 130, and the drying assembly includes a drying box for adsorption and drying, wherein a motor 340 for stirring the adsorbed particles inside the drying box is installed on the outer surface of the drying box.

[0024] The upper surface of the enclosure body 100 is designed with an opening. A fixing strip for installation and fixing is installed on the upper edge of the left and right surfaces of the enclosure body 100. The hinge 130 includes a damping telescopic rod. The rear edge of the upper surface of the enclosure body 100 is damped and hinged to the cover 120.

[0025] A damping telescopic rod is hinged between the inner surface of the lid 120 and the right inner wall of the body 100. A sealing ring is provided at the contact point between the lid 120 and the body 100. A control button 122 and a touch display screen 121 for operation are installed on the outer surface of the lid 120.

[0026] A fan 150 is installed on the front side of the right inner wall of the box body 100, and a vent 140 for ventilation is installed on the rear side of the left inner wall of the box body 100. A filter screen is installed on the outer surface of the vent 140.

[0027] In use, the user first secures the box body using the fixing plate 110, ensuring the opening on the upper surface of the box body faces forward or to the side. The specific installation method can be chosen according to the actual situation and will not be elaborated here. Once secured, the box body 100 provides a stable installation space for the electrical modules, ensuring a neat component layout. The damped hinged cover 120 allows for slow opening and closing, preventing vibrations from excessively rapid opening and closing that could affect the internal precision components. It also facilitates stable suspension at a suitable angle during maintenance and enhances the cabinet's sealing, reducing the infiltration of external humid air. Combined with the internal circulation drying component, this improves the overall moisture-proof effect and ensures safety. The system prioritizes stability, ease of operation, and environmental protection. When the enclosure 100 is in use, the fan 150 on the inner wall of the enclosure 100, along with ventilation holes and a filter, supplies and exchanges air to the enclosure 100. After supplying and exchanging air, the user can seal the ventilation holes 140 (the sealing can be done using a cover plate; specific steps and structure are not detailed here). This allows air to circulate within the enclosure 100 through the drying components. When the electrical control cabinet requires heat dissipation during use, the user can restore the ventilation holes 140 to achieve the desired cooling effect.

[0028] Please see Figures 1 to 4 As a second embodiment of the present invention: based on the description in the above embodiments, further, a drying box 300 for storing dry particles is installed on the front side of the right inner wall of the box body 100, and a box cover 330 is damped hinged on the side surface of the drying box 300 away from the box body 100, and a sealing ring is provided at the contact point between the inner surface of the box cover 330 and the drying box 300.

[0029] Multiple circular through holes 301 are evenly opened on the front and rear surfaces of the drying box 300. A motor 340 is installed on the upper surface of the drying box 300. A stirring rod is installed inside the drying box 300 by rotating the motor 340.

[0030] A heating plate 310 is provided at the connection between the drying box 300 and the box body 100. A ceramic heating element 320 is provided inside the heating plate 310. The heating surface of the heating plate 310 is located at the bottom inside the drying box 300.

[0031] A humidity sensor 200 for detecting the humidity inside the cabinet body 100 is installed at the center of the right inner wall. The humidity sensor 200 and the drying component are electrically connected to the touch screen 121 through wires.

[0032] When the drying components inside the cabinet assembly are in use, if the humidity sensor 200 on the inner wall of the cabinet body 100 detects that the humidity inside the cabinet body 100 exceeds the set humidity level, it indicates that the drying particles inside the drying box 300 have reached saturation and can no longer absorb moisture from inside the cabinet body 100, thus increasing the humidity inside the cabinet body 100. At this time, the touch display screen 121 on the outer surface of the lid 120 (the touch display screen 121, heating plate 310, humidity sensor 200, and ceramic heating element 320 are all existing technologies, and their circuit connection principles and specific structures are not described in detail here) will activate the ceramic heating element 320 inside the heating plate 310 and the motor 340 on the upper surface of the drying box 300, causing the motor 340 to circulate heat to the inside of the drying box 300. The dry granules are stirred, and then dried inside the drying box 300 by the heating plate 310, so that the saturation of the dry granules is eliminated, and the dry granules continue to dry, so that the dry granules can continue to dry, thereby achieving the purpose of circulation (however, with repeated drying, the activity of the dry granules will gradually disappear, and they need to be replaced after long-term use). After drying for a period of time, the drying component stops working, and then the dry granules are adsorbed and dried. The above operation can be repeated to carry out the drying cycle inside the box body 100. Because a drying component for adsorbing and drying the internal air is set inside the box assembly, it can efficiently adsorb the moisture in the cabinet and accurately control the humidity within a safe range, avoiding damage to components due to oxidation, short circuit or condensation caused by moisture.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
