[0015] 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.

[0016] Please see Figure 1-7 This utility model provides a technical solution: a moisture-proof switch cabinet, comprising: Dehumidifier 4 is installed at the bottom of switch cabinet 1 and is used to extract moisture from inside cabinet 1. Heat dissipation component 2 is adjustablely installed at the top of cabinet 1 and is used to control the opening and closing of the top of cabinet 1; Humidity sensor 5 is installed inside cabinet 1 and is electrically connected to dehumidifier 4 and heat dissipation component 2 via PLC control element, and is used to detect the humidity inside cabinet 1.

[0017] It should be noted that during operation, the humidity sensor 5 can monitor the humidity inside the switch cabinet 1 in real time. When the humidity inside the cabinet 1 is high, the humidity sensor 5 transmits a signal to the PLC control element. Then, the PLC control element opens the heat sink 2, creating an air vent at the top of the cabinet 1. The dehumidifier 4 then opens, expelling the humid air inside the cabinet 1 through the air vent at the top of the cabinet 1, thus keeping the inside of the cabinet 1 dry. This moisture-proof switch cabinet is equipped with a dehumidifier 4 and a heat sink 2, which work together to maintain a dry environment inside the cabinet 1. During dehumidification, the cabinet 1 is kept ventilated from top to bottom. When the dehumidifier 4 is opened, the moisture inside the cabinet 1 can be discharged from the top of the cabinet 1, improving dehumidification efficiency, effectively reducing the humidity inside the cabinet, and protecting electrical components from moisture. The humidity sensor 5 is installed inside the cabinet 1 and is electrically connected to the dehumidifier 4 through the PLC control element. It can monitor the humidity inside the cabinet in real time. When the humidity exceeds the set value, the PLC control element will promptly start the dehumidifier 4 to perform dehumidification operation, realizing intelligent moisture control and ensuring that the humidity inside the cabinet 1 is always kept within a suitable range.

[0018] In one embodiment, the bottom plate of the cabinet 1 is provided with a drawer 3 for installing a dehumidifier 4. The dehumidifier 4 includes a heating mechanism 41 disposed inside the drawer 3 and a blower mechanism 42 disposed above the heating mechanism 41. A partition 11 is provided above the drawer 3 in the cabinet 1. A ventilation slot 1101 is provided on the partition 11. A moving slot 101 for the drawer 3 to move is provided on the cabinet 1.

[0019] This design is for reference. Figure 5 ,as well as Figure 6The dehumidifier 4 consists of a heating mechanism 41 located inside the drawer 3 and a blower mechanism 42 located at its upper end. This combination design achieves a highly efficient dehumidification mode. The heating mechanism 41 can raise the ambient air temperature and reduce the relative humidity of the air, making it easier for the moisture in the air to evaporate. The blower mechanism 42 accelerates the airflow, quickly carrying away the hot air containing moisture and promoting the discharge of moisture. The two work together to greatly improve the dehumidification efficiency, which can quickly reduce the humidity inside the switch cabinet and create a dry operating environment for electrical components. The drawer 3 provides an independent installation space for the dehumidifier 4, allowing the heating mechanism 41 and the blower mechanism 42 to work in a relatively stable environment. This independent space avoids interference from other components inside the cabinet during the dehumidification process.

[0020] In one embodiment, the lower end of the drawer 3 is provided with wheels 31 for supporting the drawer 3.

[0021] This design is for reference. Figure 7 The wheel 31 makes it easier and less strenuous to pull out the drawer 3. When maintenance personnel install, inspect, repair or replace the dehumidifier 4, they do not need to exert much effort to overcome the friction between the drawer 3 and the bottom plate of the cabinet 1. They can simply pull out or push in the drawer 3 with a little force, which greatly improves the convenience of operation and reduces the labor intensity.

[0022] In one embodiment, a handle 32 is provided on one side of the drawer 3.

[0023] This design is for reference. Figure 5 ,as well as Figure 7 The handle 32 provides an easy point of leverage for the operator. When opening or closing the drawer 3, the operator can more easily apply force by holding the handle 32 to pull the drawer 3 out of the cabinet 1 or push it back.

[0024] In one embodiment, the heat dissipation component 2 includes a sealing plate 21 disposed at the upper end of the cabinet 1, an exhaust hood 22 disposed at the lower end of the sealing plate 21 and passing through the top of the cabinet 1, a connecting plate 23 disposed at the lower end of the exhaust hood 22, and a power component 24 disposed between the cabinet 1 and the connecting plate 23. The power component 24 includes, but is not limited to, a hydraulic cylinder, a linear guide rail, an electric push rod, and a pneumatic cylinder.

[0025] This design is for reference. Figure 4When the humidity inside cabinet 1 exceeds the set value, the PLC control element opens the power component 24. Then, the power component 24 drives the connecting plate 23 and the exhaust hood 22 to move up and down. The exhaust hood 22 can be adjusted to discharge from the top of cabinet 1. Then, the ventilation hole at the bottom of cabinet 1 is connected to the air outlet at the top. Then, driven by the blower mechanism 42, the humid air is discharged from the inside of cabinet 1. The exhaust hood 22 passes through the top of cabinet 1 and can quickly collect and discharge the hot air inside cabinet 1. This design prevents hot air from accumulating inside cabinet 1, effectively improves heat dissipation efficiency, and ensures that the electrical components inside the switch cabinet can work in a suitable temperature environment.

[0026] In one embodiment, the exhaust hood 22 has an opening at its lower end and exhaust ports 2201 are uniformly provided on its surface.

[0027] This design is for reference. Figure 2 ,as well as Figure 4 The lower opening of the exhaust hood 22 allows hot air to enter the exhaust hood 22 more smoothly from inside the cabinet 1. At the same time, the evenly spaced exhaust ports 2201 on its surface further increase the exhaust area, allowing more humid air to be discharged outside the cabinet through the exhaust ports 2201 at the same time.
