[0016] Third, during use, the sealing ring is beneficial to seal between the cabinet door and the power distribution cabinet body when the cabinet door is closed, effectively isolating the intrusion of external dust, water mist and other impurities, and keeping the environment inside the cabinet clean and dry. The support columns are beneficial to support the power distribution cabinet body, making the power distribution cabinet body have a certain distance from the ground, which can prevent the direct influence of moisture on the bottom. The anti-slip pads are beneficial to improve the anti-slip property of the power distribution cabinet body. The fixing frames and the dust-proof nets are beneficial to block dust, etc., effectively intercepting dust, particulate matter and other impurities in the air, keeping the air cleanliness inside the cabinet, and reducing the risk of electrical failures caused by dust accumulation.

Detailed implementation manners

[0022] The following will describe in detail the preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0023] As Figure 1 and Figure 2 shown, a power distribution cabinet with moisture-proof at the bottom includes a cabinet door 1. The cabinet door 1 is rotatably connected to the front side of the outer wall of the power distribution cabinet body 2 through a hinge. An installation groove 3 is opened on the inner bottom surface of the power distribution cabinet body 2. The right side of the outer wall of the power distribution cabinet body 2 is fixedly connected to a PLC controller. A moisture-proof pad 4 is provided inside the installation groove 3. A fixing groove 5 is opened on the inner bottom surface of the installation groove 3. A heating element 6 is fixedly installed on the inner bottom surface of the fixing groove 5. The heating element 6 is electrically connected to the PLC controller. Exhaust holes 7 are respectively opened on the left and right sides of the outer wall of the power distribution cabinet body 2. Exhaust fans 8 are respectively fixedly installed inside the two exhaust holes 7. The exhaust fans 8 are electrically connected to the PLC controller.

[0024] During use, the moisture-proof pad 4 can adsorb the moisture inside the power distribution cabinet body 2. At the same time, by starting the heating element 6 and the exhaust fans 8, automatic drying and moisture discharge can be carried out. When the moisture-proof pad 4 is saturated with water, the heating element 6 is started to an appropriate temperature to dry the moisture-proof pad 4, and at the same time, the steam is discharged through the exhaust fans 8.

[0025] The moisture-proof pad 4 is beneficial for adsorbing the moisture inside the power distribution cabinet body 2. At the same time, through the combined use of the heating element 6 and the exhaust fans 8, it is beneficial to realize the continuous recycling of the moisture-proof pad 4, thereby reducing the replacement frequency of the moisture-proof pad 4 and reducing the workload of maintaining the power distribution cabinet body 2.

[0026] As Figure 1 and Figure 2 shown, a fixing hole 9 is opened on the top surface of the power distribution cabinet body 2. A hygrometer 10 is fixedly installed inside the fixing hole 9. The hygrometer 10 is electrically connected to the PLC controller.

[0027] In use, the hygrometer 10 facilitates the real-time detection of the humidity inside the distribution cabinet body 2. When the humidity exceeds the preset threshold, the information is transmitted to the PLC controller, and the heating sheet 6 and the exhaust fan 8 are activated, enabling automatic drying and moisture discharge.

[0028] As Figures 1-3 shown, two diversion inclined plates 11 are fixed to the inner bottom surface of the distribution cabinet body 2. A number of diversion grooves 12 are respectively formed on the top surfaces of the two diversion inclined plates 11, and a sealing ring 13 is fixed to the right side of the cabinet door 1.

[0029] In use, the diversion inclined plates 11 and the diversion grooves 12 facilitate the diversion of water inside the distribution cabinet body 2, and can quickly guide the accumulated water to the moisture-proof pad 4, improving the utilization efficiency of the moisture-proof pad 4. The sealing ring 13 facilitates the sealing between the cabinet door 1 and the distribution cabinet body 2 when the cabinet door 1 is closed, effectively isolating the intrusion of external dust, water mist and other impurities, and keeping the environment inside the cabinet clean and dry.

[0030] As Figure 1 、 Figure 2 and Figure 4 shown, a number of support columns 14 are fixed to the bottom surface of the distribution cabinet body 2. Anti-slip pads 15 are respectively fixed to the bottom ends of the number of support columns 14. Fixed frames 16 are respectively fixed to the left and right outer walls of the distribution cabinet body 2, and dust-proof nets 17 are respectively fixed inside the two fixed frames 16.

[0031] In use, the support columns 14 facilitate the support of the distribution cabinet body 2, so that the distribution cabinet body 2 has a certain distance from the ground, which can prevent the direct influence of moisture on the bottom. The anti-slip pads 15 facilitate the improvement of the anti-slip property of the distribution cabinet body 2. The fixed frames 16 and the dust-proof nets 17 facilitate the blocking of dust and the like, effectively intercepting impurities such as dust and particulate matter in the air, keeping the air cleanliness inside the cabinet, and reducing the risk of electrical faults caused by dust accumulation.
