Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment protection technology, and in particular relates to a power distribution cabinet with dehumidification function. Background Technology

[0002] In fields such as power systems, industrial control, and building power distribution, the distribution cabinet is the core equipment that carries the installation of electrical components, line connection, and power distribution. The stability of its operating environment directly determines the working reliability and service life of electrical components, as well as the safe operation of the entire power distribution system.

[0003] Currently, distribution cabinets are widely used in various complex indoor and outdoor scenarios. Whether in industrial plants, commercial buildings, outdoor substations, or residential communities, distribution cabinets play a crucial role. However, these applications often come with numerous severe challenges. First, distribution cabinets are frequently exposed to rain, especially in open or semi-open environments, where rainwater can easily seep into the cabinet and damage its electrical components. Second, high humidity is another major challenge for distribution cabinets, particularly in coastal areas or basements with high humidity levels. High humidity can cause electrical equipment to become damp, affecting its normal operation. Furthermore, drastic fluctuations in humidity place higher demands on the performance of distribution cabinets. Whether in the sweltering heat of summer or the frigid cold of winter, rapid changes in humidity can trigger electrical equipment malfunctions and even lead to safety accidents. Therefore, during the design, manufacturing, and installation of distribution cabinets, these complex environmental factors must be fully considered, and effective protective measures must be taken to ensure stable and reliable operation under various harsh conditions. Summary of the Invention

[0004] In response to the above situation, in order to overcome the shortcomings of existing technologies that lack drainage structures and active dehumidification mechanisms and are unable to cope with high humidity environments.

[0005] The technical solution adopted by this utility model is as follows: A power distribution cabinet with dehumidification function includes a cabinet body, a cabinet door, and a dehumidification component. A slot is fixedly connected to the inner side of the opening of the cabinet body. Drainage outlets are symmetrically opened on the bottom side of the cabinet body. The cabinet door is rotatably mounted inside the opening of the cabinet body via a pivot. The dehumidification component is fixedly connected to the lower end of the cabinet body. The dehumidification component includes a partition, a support pipe, and a circulating fan. The upper cross-section of the partition is an isosceles triangle design. The partition is fixedly connected inside the cabinet body, dividing the interior of the cabinet body into a placement chamber and an adsorption chamber. A slot is fixedly connected to the side of the partition. A through hole connects the placement chamber and the adsorption chamber. The support tube is fixed between the partition and the bottom surface of the adsorption chamber. The support tube surrounds to form an air intake chamber. The side of the air intake chamber is provided with an air inlet that communicates with the adsorption chamber. The upper end of the air intake chamber is provided with an air outlet that communicates with the placement chamber. The circulating fan is fixed inside the air intake chamber. The air inlet end of the circulating fan communicates with the air inlet, and its air outlet end communicates with the air outlet. The adsorption chamber is filled with silica gel adsorbent. A humidity sensor and a microprocessor are fixed inside the placement chamber. The motor of the circulating fan and the humidity sensor are electrically connected to the microprocessor through wires.

[0006] Furthermore, a locking block that matches the card slot is fixedly connected to the inner side of the cabinet door, and a sealing strip is fixedly connected to the side of the locking block and the contact surface of the card slot.

[0007] Furthermore, a guide plate with an isosceles triangular cross-section is firmly connected to the top of the outer side of the cabinet. Drainage grooves are spaced apart on the guide plate, and the edge width of the guide plate extends beyond the edge of the cabinet.

[0008] Furthermore, a sealing module is provided on the rear side of the cabinet near the bottom. The sealing module includes a sleeve and a gland. The sleeve passes through the adsorption chamber and communicates with the bottom of the placement chamber. The end of the gland is threadedly connected to the inner side of the sleeve protruding from the cabinet. A silicone sealing gasket is provided inside the gland.

[0009] Furthermore, the inner corners of the cabinet are rounded, and a barrier mesh is provided inside the drain outlet.

[0010] The beneficial effects of this utility model after adopting the above structure are as follows:

[0011] This invention achieves rapid drainage of accumulated water and active adsorption and circulation of moisture through the coordinated control of the drain outlet at the bottom of the cabinet with the silica gel adsorbent, circulating fan, humidity sensor, and microprocessor in the dehumidification component. This prevents moisture buildup caused by the lack of a dedicated drainage structure, which can lead to malfunctions such as decreased insulation performance of electrical components and contact oxidation, thereby significantly improving the operational stability and reliability of the power distribution system.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0023] like Figures 1-4As shown, a power distribution cabinet with dehumidification function includes a cabinet body 10, a cabinet door 11, and a dehumidification component 20. The cabinet door 11 has an opening on one side and is rotatably mounted inside the opening of the cabinet body 10 via a pivot. A slot is fixed to the inside of the opening of the cabinet body 10. Drainage outlets are symmetrically provided on the bottom side of the cabinet body 10. The dehumidification component 20 is fixed to the lower end of the cabinet body 10 and includes a partition 21, a support pipe 25, and a circulating fan 29. The upper longitudinal section of the partition 21 is an isosceles triangle design. The partition 21 is fixed inside the cabinet body 10, dividing the interior of the cabinet body 10 into a placement cavity 22 and an adsorption cavity 23. The placement cavity is used to install electrical components such as circuit breakers, relays, etc. The partition 21 has a through hole 24 on its side, connecting the placement cavity 22 and the adsorption cavity 23. A support tube 25 is fixed between the partition 21 and the bottom surface of the adsorption cavity 23. The support tube 25 forms an air intake cavity 26. An air inlet 27 is provided between the air intake cavity 26 and the adsorption cavity 23. An air outlet 28 is provided at the upper end of the air intake cavity 26, which is connected to the placement cavity 22. A circulating fan 29 is fixed inside the air intake cavity 26. The air inlet end of the circulating fan 29 is connected to the air inlet 27, and its air outlet end is connected to the air outlet 28. The adsorption cavity 23 is filled with silica gel adsorbent. A humidity sensor and a microprocessor are fixed inside the placement cavity 22. The motor of the circulating fan 29 and the humidity sensor are electrically connected to the microprocessor through wires.

[0024] A humidity sensor monitors the humidity inside the placement chamber 22. When the humidity reaches the preset humidity threshold, the microprocessor controls the circulation fan 29 to start. The humid air inside the placement chamber 22 enters the adsorption chamber 23 through the through hole 24 of the partition 21. After being dehumidified by the silica gel adsorbent, it enters the suction chamber 26 through the air inlet 27 and finally flows back to the placement chamber 22 through the air outlet 28, forming a continuous dehumidification cycle.

[0025] It should be noted that the middle of the bottom of the adsorption chamber 23 is higher than the drain outlet. The water adsorbed by the silica gel adsorbent can flow along the wall of the adsorption chamber 23 to the drain outlet due to its own gravity.

[0026] In one embodiment of this utility model, such as Figure 1 and Figure 3 As shown, a card slot block 12 that matches the card slot is fixed to the inside of the cabinet door 11. A sealing strip is fixed to the side of the card slot block 12 that is in contact with the card slot, which can strengthen the barrier against external moisture and rainwater seepage.

[0027] In one embodiment of this utility model, such as Figure 1 As shown, a guide plate 13 with an isosceles triangular cross-section is firmly connected to the top of the outer side of the cabinet 10. Drainage grooves 14 are spaced apart on the guide plate 13. The edge width of the guide plate 13 exceeds the edge of the cabinet 10, which can efficiently guide rainwater to flow away and prevent rainwater from directly washing the cabinet 10.

[0028] In one embodiment of this utility model, such as Figure 4 As shown, a sealing module 30 is also provided on the rear side of the cabinet 10 near the bottom. The sealing module 30 includes a sleeve 31 and a gland 32. The sleeve 31 passes through the adsorption chamber 23 and communicates with the bottom of the placement chamber 22. The end of the gland 32 is threadedly connected to the inner side of the sleeve 31 protruding from the cabinet 10. A silicone sealing gasket 33 is provided inside the gland 32, which realizes the sealing treatment of the line entry and exit and prevents moisture from entering from the line interface.

[0029] In one embodiment of this utility model, the inner corners of the cabinet 10 are rounded, and a barrier net is provided on the inner side of the drain outlet to reduce water accumulation dead corners. It can stably cope with harsh scenarios such as open-air substations, coastal high-humidity environments, and basements, effectively protecting electrical components from the effects of rain, high humidity, and humidity fluctuations, and extending the service life of electrical components and the overall service cycle of the distribution cabinet.

[0030] In practical use, when the distribution cabinet is outdoors in rainy weather, the top guide plate 13 diverts rainwater through the drainage channel 14; if water accumulates inside the cabinet, the water is discharged through the drain (the barrier net prevents debris from clogging); when the humidity sensor detects that the humidity exceeds the standard, the microprocessor starts the circulation fan 29, which adsorbs moisture through the silica gel in the adsorption chamber 23 to form a continuous dehumidification cycle.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents. In conclusion, if those skilled in the art, inspired by this description, design similar structural methods and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
