[0058] It should be noted that the power equipment is placed inside the inner shell 11 to protect it from damage. A switch door 16 is provided on the side of the cabinet 10. The switch door 16 is also a double-layer structure. When closed, it is aligned with the inner shell 11 and the outer shell 12 respectively.

[0059] like Figure 1 and Figure 2 As shown, the outer shell 12 is provided with a plurality of air inlets and a plurality of air outlets equidistantly and staggeredly along the circumferential direction, and the air inlets penetrate the outer shell 12 , the inner shell 11 and the water curtain bin 13 , and the air outlets penetrate the outer shell 12 and the inner shell 11 .

[0060] Specifically, the housing 12 is provided with two air inlets and two air outlets equidistantly and staggeredly along the circumferential direction.

[0061] The water absorption component includes a plurality of flexible water absorption blocks 31 and a rotating drive component. The flexible water absorption blocks 31 are arranged between the inner shell 11 and the outer shell 12, corresponding one to the air inlet and the air outlet, and the plurality of flexible water absorption blocks 31 are connected to the rotating drive component and aligned with the air inlet or the air outlet under the drive of the rotating drive component.

[0062] It should be noted that the flexible water-absorbing block 31 has good water absorption, can absorb moisture in the passing air, and can be dried by squeezing, blowing, etc., to achieve the effect of recycling; specifically, the flexible water-absorbing block 31 is a water-absorbing sponge block.

[0063] like Figure 1 and Figure 2 As shown, the water curtain assembly is arranged in the water curtain bin 13; the fan 50 is connected to the housing 12 and aligned with the air outlet.

[0064] like Figure 1 and Figure 3 As shown, in a specific implementation of the cooling protection system for electric power equipment provided in an embodiment of the present invention, the water curtain assembly includes a water absorption and breathable plate 21, a water distribution tank 14 and a circulating pump 24, the water absorption and breathable plate 21 is arranged between the inner shell 11 and the outer shell 12, connected to the inner shell 11 or the outer shell 12 and aligned with the air inlet; the water distribution tank 14 is arranged on the upper side of the water absorption and breathable plate 21, and a plurality of drainage holes are provided at the bottom of the water distribution tank 14; the space between the outer shell 12 and the inner shell 11 is used as a water storage tank 15, and the water storage tank 15 is connected to the bottom of the water curtain tank 13; the water inlet end of the circulating pump 24 is connected to the water storage tank 15, and the water outlet end is connected to the water distribution tank 14.

[0070] It should be noted that the holes on the water-absorbing and breathable plate 21 correspond one-to-one with the drainage holes at the bottom of the water distribution bin 14 and are aligned one-to-one. The water in the water distribution bin 14 flows into the holes on the water-absorbing and breathable plate 21 through the drainage holes, and then flows downward along the spiral blades 23 and enters the water-absorbing and breathable plate 21 at the same time, which can greatly increase the contact area between the water flow and the water-absorbing and breathable plate 21, so that the water flow can quickly flow through the water-absorbing and breathable plate 21, thereby ensuring the cooling efficiency of the passing air.

[0076] like Figure 4 As shown, in a specific implementation of the cooling protection system for electric power equipment provided by an embodiment of the present invention, the distance between the inner shell 11 and the outer shell 12 gradually decreases from the air inlet to the air outlet.

[0077] Specifically, after a certain period of time, the rotating drive component drives the flexible water-absorbing block 31 at the air inlet to rotate to the air outlet, and simultaneously squeezes the flexible water-absorbing block 31 to initially squeeze out the water therein, thereby accelerating its drying speed.

[0078] like Figure 3 and Figure 4 As shown, in a specific implementation of the cooling protection system for electric power equipment provided in an embodiment of the present invention, the rotation drive assembly includes a rotating frame 33, a plurality of connecting frames 32 and a driving mechanism 34, and the rotating frame 33 rotates with the cabinet 10; the driving mechanism 34 is connected to the cabinet 10, and the power output end is connected to the rotating frame 33 to drive the rotating frame 33 to rotate; the plurality of connecting frames 32 are all connected to the rotating frame 33, and the connecting frames 32 correspond to the flexible water absorbent blocks 31 one by one, and are connected to the flexible water absorbent blocks 31.

[0080] like Figure 3 and Figure 4 As shown, in a specific implementation of the cooling protection system for electric power equipment provided in an embodiment of the present invention, it also includes a plurality of drying plates 40, which correspond one-to-one to the air inlets and are arranged on the inner side of the flexible water-absorbing block 31 and connected to the inner shell 11.

[0081] Specifically, a drying plate 40 is arranged inside the flexible water-absorbing block 31 to further absorb moisture in the air, thereby improving the dryness of the environment inside the inner shell 11 .

[0082] The beneficial effect of the cooling protection system for electric equipment provided by the embodiment of the present invention is as follows: compared with the prior art, during operation, the fan 50 on the outer casing 12 exhausts air outward, and the external air passes through the water curtain assembly in the water curtain bin 13, so that the air is cooled and dust in the air is filtered out, and the cooled air continues to pass through the flexible water absorbent block 31, and the moisture in the cooling air is absorbed by the flexible water absorbent block 31.

[0083] Afterwards, the cooled and dried air enters the inner shell 11 to cool the internal electrical equipment and is discharged from the air outlet.

[0084] At the same time, after a certain period of time, the rotary drive component drives the flexible water absorbent block 31 to rotate, and turns the flexible water absorbent block 31 at the air inlet to the air outlet. In this process, the moisture in the flexible water absorbent block 31 is initially squeezed out to make it air-dried, and the dry flexible water absorbent block 31 at the original air outlet is turned to the air inlet to continue absorbing moisture in the air passing through the water curtain component, thereby achieving the purpose of continuous drying.

[0085] Therefore, the cooling protection system for the power equipment provided in the embodiment of the present invention lowers the air temperature by arranging a water curtain assembly at the air inlet, so that the cooled air flows through the surface of the power equipment, thereby improving the heat dissipation efficiency, and filters out dust in the air through the water curtain assembly, effectively preventing dust from accumulating in the cabinet 10; at the same time, through the cooperation of the flexible water-absorbing block 31 and the rotating drive assembly, the moisture carried by the air passing through the water curtain assembly is continuously absorbed to keep the inside of the cabinet 10 dry.

[0086] That is, the cooling and protection system for electric power equipment provided by the embodiment of the present invention integrates the functions of protection, dust removal, cooling and drying.
