[0011] The beneficial effects of the present invention are as follows:

[0012] 1. The present invention sets a rain shielding mechanism. On sunny days, a motor drives a group of first guide plates to unfold, so as to reduce direct sunlight on the main body and affect the temperature inside the main body. On rainy days, the first guide plate and the second guide plate are spread out to completely shield the main body and collect rain. The first guide plate and the second guide plate are both arranged in an arc shape with an outward-turned groove at the bottom. Rainwater enters the groove through the arc surface and then flows into the water storage tank. Impurities are filtered through the sieve plate. The filtered rainwater enters the collecting pipe and then enters the cooling box, which is used for cooling the inside of the main body and reducing dust in the air, saving water resources and making full use of them, which helps to reduce maintenance costs.

[0013] 2. The present invention sets a pretreatment mechanism. Before the air enters the cabinet, it is first preliminarily filtered through the dust net laid inside the limit ring. Under the action of the airflow, the fan blades start to rotate, thereby driving the turntable to rotate, and then the curved rod drives the scraper block to rotate to clean the surface of the dust net. The curved rod can block and shield large impurities in the air to prevent the dust net from being blocked and air from entering. The air is preliminarily filtered and protected from the outside, thereby strengthening the cleaning of the interior of the cabinet and further avoiding dust accumulation inside the cabinet, which makes it difficult for components to dissipate heat and increases the difficulty of cleaning.

[0014] 3. The present invention provides a dust reduction mechanism, and air enters the processing box through a screen provided on the surface of the cabinet. After the water in the cooling box is cooled inside the main mechanism, it is connected to the connecting valve through a hose and enters the processing box through the connecting valve. The upper half of the processing box is hollow, and a small hole is opened on the top of the inner wall at the corresponding position of the processing box. The circulating water enters the hollow cavity and spreads out, so that the water penetrates from the small hole and contacts with the air just entering, and the air is subjected to dust reduction treatment. In addition, the interior of the processing box is divided into a serpentine corridor by the partition, so that the residence time of the air in the processing box is prolonged, and dust is prevented from entering the cabinet, effectively reducing the influence of dust on the circuit and components, and reducing the maintenance cost and difficulty. At the same time, the cold air enters the processing box and flows, which can make the air perform heat exchange cooling on the chassis, accelerate the cooling speed of the chassis, keep the air entering the cabinet dry, clean the air entering the cabinet, slow down the accumulation of dust, extend the time for cleaning and maintenance of the cabinet, and facilitate the long-term operation of the cabinet.

[0015] 4. The present invention arranges an extrusion component, and the sponge strip close to the air inlet is filled with water, so that the dust in the air adheres to the sponge to perform dust reduction treatment. The sponge strip at one end away from the air inlet is kept dry and absorbs moisture in the air, allowing dry air to enter the interior of the cabinet, thereby achieving the purpose of reducing the humidity inside the cabinet and avoiding short circuits or dangers of components caused by excessive humidity. When too much water accumulates in the sponge, the first rotating plate and the second rotating plate approach each other to squeeze the sponge strip, squeeze out the water and enter the bottom of the treatment box through the separation plate, which is convenient for long-term use.
