A baffle 204 is fixedly connected to the arc surface of the rotating rod 203. A dust-proof net 205 is slidably connected to the inner surface of the dust-proof frame 201. The dust-proof net 205 is located directly in front of the heat dissipation holes of the grid-connected cabinet body 1. Two fixing rods 206 are fixedly connected to the surface of the dust-proof frame 201. An operating plate 207 is slidably connected to the arc surface of the fixing rod 206. A limiting rod 208 is fixedly connected to the side of the operating plate 207 close to the dust-proof frame 201. Two limiting blocks 209 are fixedly connected to the surface of the baffle 204. A limiting groove is opened on the surface of the limiting block 209. The size of the limiting rod 208 is adapted to the size of the limiting groove of the limiting block 209. When the dust-proof net 205 has been used for a long time, a large amount of dust will adhere to the surface of the dust-proof net 205. In order not to affect the heat dissipation of the heat dissipation holes of the grid-connected cabinet body 1, the staff needs to clean the dust on the surface of the dust-proof net 205 in time. Pull the operating plate 207, and the operating plate 207 slides on the arc surface of the fixing rod 206. The operating plate 207 drives the limiting rod 208 to move. When the limiting rod 208 completely disengages from the inner surface of the limiting groove of the limiting block 209, the limiting rod 208 releases the fixation of the baffle 204. Rotate the baffle 204, and the baffle 204 drives the rotating rod 203 to rotate on the surface of the rotating block 202. When the baffle 204 is completely opened, move the dust-proof net 205, and the dust-proof net 205 slides on the inner surface of the dust-proof frame 201. When the dust-proof net 205 completely disengages from the inner surface of the dust-proof frame 201, the staff can clean the dust on the surface of the dust-proof net 205. After cleaning, put the dust-proof net 205 back in place, close the baffle 204, and push the operating plate 207. The operating plate 207 drives the limiting rod 208 to move. When the limiting rod 208 is inserted into the inner surface of the limiting groove of the limiting block 209, the limiting rod 208 fixes the baffle 204, achieving the effect of being able to fix the baffle 204. At the same time, it is convenient for the staff to quickly open the baffle 204, take out the dust-proof net 205 and clean the dust-proof net 205. Two torsion springs 210 are sleeved on the arc surface of the rotating rod 203. The two ends of the torsion spring 210 are respectively fixedly connected to the rotating block 202 and the baffle 204. When the staff needs to open the baffle 204, move the operating plate 207, and the operating plate 207 drives the limiting rod 208 to move. When the limiting rod 208 completely disengages from the inner surface of the limiting groove of the limiting block 209, the limiting rod 208 releases the fixation of the baffle 204. The torsion of the torsion spring 210 drives the baffle 204 to rotate. The baffle 204 drives the rotating rod 203 to rotate on the surface of the rotating block 202 until the baffle 204 is completely opened. The torsion of the torsion spring 210 achieves the effect of automatically opening the baffle 204 and keeping the baffle 204 in the open state, thus facilitating the staff to move the dust-proof net 205. Connecting grooves are opened on the surface of the dust-proof net 205.A handle 211 is fixedly connected to the inner surface of the dust-proof net 205 connection groove. When the staff needs to clean the dust on the surface of the dust-proof net 205, the operation board 207 is moved. The operation board 207 drives the limit rod 208 to move. When the limit rod 208 completely disengages from the inner surface of the limit groove of the limit block 209, the baffle 204 is rotated. After the baffle 204 is completely opened, the handle 211 is moved. The handle 211 drives the dust-proof net 205 to move. When the dust-proof net 205 completely disengages from the inner surface of the dust-proof frame 201, the staff can clean the dust on the surface of the dust-proof net 205, achieving the effect of facilitating the staff to move the dust-proof net 205 and avoiding the situation that there is no suitable force point on the surface of the dust-proof net 205, resulting in the inconvenience for the staff to move the dust-proof net 205.

[0032] Referring Figure 4 and Figure 5 As shown in the figure, specifically, the sunshade device 3 includes a fixing plate 31. The fixing plate 31 is fixedly connected to the surface of the grid-connected cabinet body 1. A round rod 32 is rotatably connected to the surface of the fixing plate 31. A sunshade plate 33 is fixedly connected to the arc surface of the round rod 32. Two connecting rods 34 are fixedly connected to the surface of the fixing plate 31. One end of the connecting rod 34 far from the fixing plate 31 is fixedly connected to a connecting plate 35. A plug rod 36 is slidably inserted into the connecting plate 35. Two slots are formed on the surface of the sunshade plate 33. The size of the slots of the sunshade plate 33 is adapted to the size of the plug rod 36. One end of the plug rod 36 is fixedly connected to an operation block 37. When the staff needs to cover the sunshade plate 33 on the surface of the grid-connected cabinet body 1, the operation block 37 is moved. The operation block 37 drives the plug rod 36 to move. When the plug rod 36 moves to a suitable position, the sunshade plate 33 is rotated. The sunshade plate 33 drives the round rod 32 to rotate. When the sunshade plate 33 rotates to directly above the grid-connected cabinet body 1, the plug rod 36 is located directly in front of the slot of the sunshade plate 33. The operation block 37 is pushed. The operation block 37 drives the plug rod 36 to move. When the plug rod 36 is inserted into the inner surface of the slot of the sunshade plate 33, the plug rod 36 fixes the sunshade plate 33, achieving the effect of fixing the sunshade plate 33 and avoiding the situation that the sunshade plate 33 is blown by the wind, resulting in the sunshade plate 33 flipping and reducing the sunshade effect of the sunshade plate 33. A spring 38 is sleeved on the arc surface of the plug rod 36. Two ends of the spring 38 are respectively fixedly connected to the operation block 37 and the connecting plate 35. When the staff pulls the operation block 37, the spring 38 is stretched. The operation block 37 drives the plug rod 36 to move. When the plug rod 36 moves to a suitable position, the sunshade plate 33 is rotated. When the sunshade plate 33 is rotated to directly above the grid-connected cabinet body 1, the operation block 37 is released. The resilience of the spring 38 drives the operation block 37 to move. The operation block 37 drives the plug rod 36 to move until the plug rod 36 is inserted into the inner surface of the slot of the sunshade plate 33. The resilience of the spring 38 achieves the effect of automatically inserting the plug rod 36 and simultaneously restricts the operation block 37 from driving the plug rod 36 to move, improving the stability of the plug rod 36 during limiting.

[0033] Working principle: After the dust-proof net 205 has been used for a long time, a large amount of dust will adhere to the surface of the dust-proof net 205. In order not to affect the heat dissipation of the heat dissipation holes of the grid-connected cabinet body 1, the staff needs to clean the dust on the surface of the dust-proof net 205 in time. Pull the operation board 207, and the operation board 207 slides on the arc surface of the fixed rod 206. The operation board 207 drives the limit rod 208 to move. When the limit rod 208 completely disengages from the inner surface of the limit groove of the limit block 209, the limit rod 208 releases the fixation of the baffle 204. The torsion of the torsion spring 210 drives the baffle 204 to rotate. The baffle 204 drives the rotating rod 203 to rotate on the surface of the rotating block 202. When the baffle 204 is completely opened, move the handle 211. The handle 211 drives the dust-proof net 205 to move. The dust-proof net 205 slides on the inner surface of the dust-proof frame 201. When the dust-proof net 205 completely disengages from the inner surface of the dust-proof frame 201, the staff can clean the dust on the surface of the dust-proof net 205. After cleaning, put the dust-proof net 205 back in place, close the baffle 204, and push the operation board 207. The operation board 207 drives the limit rod 208 to move. When the limit rod 208 is inserted into the inner surface of the limit groove of the limit block 209, the limit rod 208 fixes the baffle 204.

[0034] When the staff needs to cover the sunshade 33 on the surface of the grid-connected cabinet body 1, move the operation block 37. The spring 38 is stretched. The operation block 37 drives the insertion rod 36 to move. When the insertion rod 36 moves to a suitable position, rotate the sunshade 33. The sunshade 33 drives the round rod 32 to rotate. When the sunshade 33 rotates to directly above the grid-connected cabinet body 1, the insertion rod 36 is located directly in front of the slot of the sunshade 33. Release the operation block 37. The resilience of the spring 38 drives the operation block 37 to move. The operation block 37 drives the insertion rod 36 to move.
