[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-6The utility model provides a technical solution: a low-voltage power distribution cabinet with a drying function, comprising a cabinet body 100 and a cabinet door 200 hinged on the front of the cabinet body 100, and a drainage assembly 300 assembled inside the cabinet body 100, the bottom of the front and the bottom of the back of the cabinet body 100 are respectively equipped with an exhaust fan 110 and an exhaust fan 120, the drainage assembly 300 comprises a condensation plate 310 welded to the bottom of the inner side of the cabinet body 100 in an inclined direction and a vertical plate 320 erected on the inner rear part of the cabinet body 100 in a vertical direction, the bottom of the condensation plate 310 is provided with a vertically connected A partition 330 extends downward, and the top of the condensation plate 310 is provided with a mounting plate 340 which is integrally connected thereto and extends vertically upward. A fixing plate 350 which is in the same vertical plane as the mounting plate 340 is welded to the top of the inner side of the cabinet body 100. The vertical plate 320 is covered and installed between the fixing plate 350 and the mounting plate 340. The front of the vertical plate 320 is provided with a plurality of ventilation holes 360 which are distributed along its width direction. The plurality of ventilation holes 360 are evenly distributed at equal distances in the vertical direction, and the bottoms of the plurality of ventilation holes 360 are provided with guide plates 370 which extend obliquely upward.

[0030] Based on the above-mentioned structural setting, the low-voltage distribution cabinet with drying function is composed of a cabinet 100, a cabinet door 200 and a drainage assembly 300, wherein the cabinet door 200 is hinged to the front of the cabinet 100, the exhaust fan 110 is installed at the bottom of the front of the cabinet 100, and the induced draft fan 120 is installed at the bottom of the back of the cabinet 100. The drainage assembly 300 is assembled inside the cabinet 100 and separates the exhaust fan 110 and the induced draft fan 120 while draining the wind inside the cabinet 100. Specifically, during operation, the induced draft fan 120 introduces wind into the cabinet 100. Since the newly introduced cold wind continues to blow toward the back of the condensation plate 310, the temperature of the condensation plate 310 is always low. At the same time, under the obstruction of the condensation plate 310 and the partition 330, the wind entering the cabinet 100 can only pass through the vertical The air flows upward between the plate 320 and the back plate of the cabinet 100, and is blown toward the components through a number of guide plates 370 to cool the components. At the same time, under the action of the exhaust fan 110, the airflow after heat exchange flows downward and condenses into water droplets after contacting the condensation plate 310, and is finally output with the exhaust fan 110. The low-voltage distribution cabinet with drying function is provided with a drainage component 300 to replace the traditional water-cooled condensation with air-cooled condensation. While cooling and dissipating the heat inside the distribution cabinet, the exhaust fan 110 and the exhaust fan 120 can be used to make the hot gas or humid gas inside the cabinet 100 contact with the condensation plate 310 with a lower temperature and convert it into liquid, thereby achieving drying inside the distribution cabinet. Compared with the traditional water-cooled condensation, no additional cooling water system is required, thereby reducing the installation and operation costs.

[0031] Furthermore, the back of the exhaust fan 120 is covered with a primary filter 130. The primary filter 130 uses fine mesh and cotton material to intercept large particles and dust in the air. In a humid environment, the primary filter 130 helps to reduce the damp dust and particles condensed due to the humid environment, thereby indirectly playing a certain moisture-proof effect and preventing the introduced airflow from containing too much moisture.

[0032] Furthermore, the condensation plate 310 is in a wave plate structure. The condensation plate 310 is used to condense moisture in the wind flow on one hand, and on the other hand, the inclined installation method can guide the water droplets formed by condensation. As a preferred embodiment, the wave plate structure is adopted to increase the contact area between the wind flow and the condensation plate 310, thereby improving the condensation efficiency. At the same time, the design of the wave plate structure helps the water droplets to converge on the condensation plate 310 in advance, thereby improving the guiding effect.

[0033] Furthermore, two channel steels 400 are provided at the bottom of the cabinet 100, the partition 330 and the inner wall of the cabinet 100 form a cavity for condensed water to collect, and a drain pipe 150 is installed through the middle of the bottom wall of the cavity, and two symmetrically distributed inclined plates 140 are respectively provided on the left and right sides of the front of the partition 330, and the two inclined plates 140 cover the left and right sides welded to the inside of the cavity. Among them, the arrangement of the channel steel 400 lifts the cabinet 100 off the ground, reduces the water vapor on the ground in the humid environment from penetrating into the cabinet 100, and at the same time, provides an accommodation space for the installation of the drain pipe 150, and the two symmetrically distributed inclined plates 140 in the cavity facilitate the water droplets converging in the cavity to be discharged from the drain pipe 150. For a highly humid environment, the operator needs to open the drain pipe 150 so that a large amount of condensed water droplets can be directly discharged through the drain pipe 150 after converging, and under normal circumstances, a small amount of condensed water droplets can be directly output through the exhaust fan 110.

[0034] Furthermore, rubber pads 380 are glued to the top and bottom of the front of the vertical plate 320, and the two rubber pads 380 are distributed along the width direction of the vertical plate 320. The two rubber pads 380 are respectively arranged between the vertical plate 320 and the fixing plate 350 and the mounting plate 340, ensuring the sealing between the vertical plate 320 covering and installing the fixing plate 350 and the mounting plate 340.
