[0027] The heat dissipation mechanism 2 comprises a plurality of air guide vanes 21 connected in the hole bodies of the heat dissipation holes 3 and a heat dissipation fan 22 arranged at one side of the air guide vanes 21, and the heat dissipation fan 22 is connected to the inner wall of the cabinet body 1;

[0028] The hole inner walls of the heat dissipation holes 3 are connected with a plurality of insect blocking assemblies 23, and the air guide vanes 21 are located between two adjacent insect blocking assemblies 23.

[0029] Optionally, as shown in Figure 1 Both ends of the heat dissipation fan 22 are connected with connecting ears 221, one end of the connecting ears 221 away from the heat dissipation fan 22 is connected with the inner wall of the cabinet body 1, and a gap is arranged between the inner wall of the cabinet body 1 and the heat dissipation fan 22.

[0030] In the embodiments, the connecting ears 221 are arranged to connect the heat dissipation fan 22 and the inner wall of the cabinet body 1. The gap between the inner wall of the cabinet body 1 and the heat dissipation fan 22 can fill the hole bodies of the heat dissipation holes 3 with the air flow discharged by the heat dissipation fan 22, expand the air outlet area, and facilitate the discharge of hot air.

[0031] Optionally, as shown in Figure 1 The insect blocking assembly 23 comprises a shielding piece 231 rotationally connected in the hole body of the heat dissipation hole 3, and an inner side surface of the top end of the shielding piece 231 is provided with a weight-reducing groove 232.

[0032] In the embodiments, the shielding piece 231 shields the heat dissipation hole 3 when the heat dissipation fan 22 is not working. The rotation of the shielding piece 231 in the heat dissipation fan 22 enables the hot air flow to push away the shielding piece 231 and discharge to the outside. The arrangement of the weight-reducing groove 232 makes the top end of the shielding piece 231 light and the bottom end heavy, thereby facilitating the shielding piece 231 to fall and shield the hole body.

[0033] Optionally, as shown in Figure 1 and Figure 3As shown, the hole body of the heat dissipation hole 3 is sequentially provided with a rotating shaft 31 from top to bottom, the rotating shaft 31 penetrates through the plurality of air guide blades 21, and the shielding piece 231 is connected to the outer surface of the shaft body of the adjacent rotating shaft 31.

[0034] In the embodiment, the shielding piece 231 can rotate in the heat dissipation hole 3 through the arrangement of the rotating shaft 31.

[0036] In the embodiment, the gap between the shielding piece 231 and the air guide blade 21 is further reduced through the arrangement of the shielding strip 32 in the hole body of the heat dissipation hole 3, so that the heat dissipation hole 3 is opened and the hot air is discharged.

[0037] Optionally, as shown in Figure 1 and Figure 3 As shown, the two ends of the shielding piece 231 are provided with a fillet surface.

[0038] In the embodiment, the fillet surface at the two ends of the shielding piece 231 is arranged, so that when the two shielding pieces 231 are pushed by the airflow, they do not interfere with each other and are not interfered by the inner wall of the hole body of the heat dissipation hole 3, so as to open the heat dissipation hole 3 and facilitate the discharge of hot air.

[0039] Optionally, as shown in Figure 1 and Figure 3 As shown, the shielding piece 231 is located in the hole body of the heat dissipation hole 3 away from the heat dissipation fan 22.

[0040] In the embodiment, since the shielding piece 231 is located at one end of the heat dissipation hole 3 away from the heat dissipation fan 22, the shielding piece 231 is convenient for shielding insects.

[0041] The specific operation mode of the utility model is as follows:

[0042] When the low-voltage anti-open-phase protection cabinet is used, the hot air generated by the components in the cabinet body 1 is guided by the heat dissipation fan 22 and blown to the heat dissipation hole 3. The hot air in the heat dissipation hole 3 pushes away the shielding strip 32, so as to flow out to the outside. At this time, the discharged hot air blocks mosquitoes from entering the cabinet body, preventing mosquitoes from affecting the work of the components in the cabinet body.

[0043] When the heat dissipation fan 22 is not working, the heat dissipation hole 3 is shielded by the shielding strip 32, so as to prevent mosquitoes from entering the heat dissipation hole 3.
