DETAILED DESCRIPTION

[0017] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0018] Embodiment 1:

[0019] like Figure 1-4As shown, a corrosion-resistant switchgear comprises a switch cabinet body 100, wherein air intake pipes 101 are fixedly installed at both left and right ends of the switch cabinet body 100, a first air intake port 102 penetrating the outside of the switch cabinet body 100 is provided at the lower part of the air intake pipe 101, a second air intake port 103 is provided at the upper end of the air intake pipe 101, an air intake fan 104 is fixedly installed on the inner side of the first air intake port 102, an installation slot 105 penetrating the outside of the switch cabinet body 100 is provided at the upper part of the air intake pipe 101, and an installation slot 105 penetrating the outside of the switch cabinet body 100 is provided. A drying box 106 is slidably installed in the groove 105, and both the upper and lower ends of the drying box 106 are designed for ventilation. A desiccant 107 is placed in the drying box 106. By setting the air intake duct 101, external air needs to pass through its internal mechanism to enter the switch cabinet body 100. By setting the air intake fan 104, the air intake volume is increased. By setting the drying box 106 and the desiccant 107, the incoming air is dried to avoid corrosion of internal components due to excessive air humidity.

[0020] A plurality of partitions 200 are fixedly installed in the drying box 106, and the plurality of partitions 201 are divided into a first partition 201 and a second partition 202. The first partition 201 is connected to the front side of the drying box 106 and has a gap with the rear side of the drying box 106. The second partition 202 is connected to the rear side of the drying box 106 and has a gap with the front side of the drying box 106. By providing the first partition 201 and the second partition 202, the travel distance of the air in the drying box 106 is increased, thereby improving the drying effect.

[0021] A dustproof net 301 is fixedly installed at the lower end of the drying box 106 to prevent dust from entering the interior of the switch cabinet body 100 .

[0022] A dust collecting box 302 is provided at the lower part of the air inlet duct 101 so that the dust blocked by the dustproof net 301 can fall down and be collected.

[0023] The drying box 106 and the dust box 302 are both provided with a handle 303 on the outer side, so as to facilitate the extraction of the drying box 106 and the dust box 302 for cleaning and maintenance.

[0024] An isolation door 304 is provided at the front end of the switch cabinet body 100 to isolate the inside of the switch cabinet body 100 from the outside.

[0025] When this embodiment is in use, the outside air is sucked into the air intake duct 101 from the first air inlet 102 through the air intake fan 104. After entering the air intake duct 101, the air moves upward along the air intake duct 101. When entering the drying box 106, the dust in the air is first blocked by the dustproof net 301. The blocked dust falls into the dust collecting box 302 due to gravity and continues to move. The air moves in the drying box 106 along the gap between the first partition 201 and the second partition 202, and the desiccant 107 therein absorbs moisture in the air to reduce the humidity of the air. Finally, the air enters the interior of the switch cabinet body 100 from the second air inlet 103.

[0026] In this embodiment, an air intake duct 101 is provided so that external air needs to pass through its internal mechanism before entering the switch cabinet body 100. An air intake fan 104 is provided to increase its air intake volume. A drying box 106 and a desiccant 107 are provided to dry the incoming air to avoid corrosion of internal components due to excessive air humidity. A first partition 201 and a second partition 202 are provided to increase the travel distance of air in the drying box 106, thereby improving the drying effect. A dustproof net 301 is provided to prevent dust from entering the switch cabinet body 100.

[0027] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
