The left and right sides of the second rotating groove 15 are rotatably connected to a second rotating block 17 through a second rotating shaft 16. The second rotating block 17 is provided with a second mounting groove 18; The second filter roller 19 includes a second roller body 20 and second roller protrusions 21 fixed at both ends of the second roller body 20. The two second roller protrusions 21 are respectively installed in the two second installation grooves 18. The second roller protrusions 21 are detachably connected to the second rotating block 17. A filter belt roll 22 is wound on the second filter roller 19. The filter belt roll 22 is provided with filter holes 23. The outer end of the filter belt roll 22 is fixedly connected to the outer wall of the first winding roller 11. The filter belt 24 between the first winding roller 11 and the second filter roller 19 covers the air outlet 4. The roller driving device is used to drive the first rotating shaft 8 to rotate.

[0019] The air inlet device 5 supplies air to the cabinet cavity 2, and the supplied air can cool down the electrical components of the control cabinet, and then the air passes through the air outlet 4 and blows out from the filter hole 23. When the filter belt 24 needs to be replaced after a long time, the roller driving device drives the first rotating shaft 8 to rotate, thereby driving the first winding roller 11 to rotate. The rotation of the first winding roller 11 can wind the filter belt roll 22 that needs to be replaced around the first winding roller 11, and then drive the new filter belt 24 on the filter belt roll 22 to the outside of the air outlet 4 for filtering.

[0020] like Figure 7 As shown, the first roller body 12 includes a first upper roller body 25 and a first lower roller body 26, the first upper roller body 25 and the first lower roller body 26 are a circular roller body, the first roller protrusion 13 includes a first roller upper protrusion 27 and a first roller lower protrusion 28, the first roller upper protrusion 27 and the first roller lower protrusion 28 are respectively provided with a first upper through hole 29 and a first lower through hole 30, the bottom surface of the first mounting groove 10 is provided with a first threaded hole 31, the first upper through hole 29 and the first lower through hole 30 are penetrated by a first connecting bolt 32 threadedly connected to the first threaded hole 31, the first upper roller body 25 and the first lower roller body 26 clamp the outer end of the filter belt roll 22.

[0021] When it is necessary to fix the outer end of the filter belt roll 22 on the first roller body 12, the first connecting bolt 32 can be loosened first, and then the first upper roller body 25 can be picked up, and then the outer end of the filter belt roll 22 can be placed between the first upper roller body 25 and the first lower roller body 26, and finally the first connecting bolt 32 can be rotated to fix the first roller upper protrusion 27 and the first roller lower protrusion 28 in the first mounting groove 10. At this time, the first upper roller body 25 and the first lower roller body 26 clamp the outer end of the filter belt roll 22, and the first connecting bolt plays a role of clamping the outer end of the filter belt roll 22 while fixing the first roller upper protrusion 27 and the first roller lower protrusion 28.

[0022] like Figure 1-Figure 3 As shown, the filtering device also includes a pressing assembly, and the pressing assembly includes: A pressing seat 33, which is arranged on the right side of the air outlet 4, and a pressing groove 36 is provided on the pressing seat 33; A clamping frame 35 is rotatably connected to a clamping groove 36. Clamping members are installed on the upper and lower sides of the clamping frame 35. The clamping members include two clamping rods 37. The clamping frame 35 is provided with a clamping through hole 38 for the clamping rods 37 to pass through. A first clamping connecting rod 39 is fixed between one end of the two clamping rods 37, and a second clamping connecting rod 40 is fixed at the other end. A clamping roller 41 is rotatably connected to the second clamping connecting rod 40, and the outer wall of the clamping roller 41 abuts against the filter belt 24. A clamping spring 42 is sleeved on the clamping rod 37, and the clamping spring 42 is arranged between the second clamping connecting rod 40 and the clamping frame 35.

[0023] When the outer wall of the pressing roller 41 abuts against the filter belt 24, the pressing spring 42 is in a compressed state, so that the filter belt 24 is flatly pressed against the outer wall of the cabinet 1, and the filtering effect is better played. When the filter belt roll 22 is used up and needs to be replaced, it is only necessary to rotate the pressing frame 35 away from the cabinet 1, so that the outer end of the new filter belt roll 22 can be conveniently installed between the first upper roller body 25 and the first lower roller body 26.

[0024] like Figure 3 and Figure 8 As shown, the clamping frame 35 is provided with a limit slide groove 43 opening downward, a limit rod 44 is inserted in the limit slide groove 43, and a limit groove 45 is provided on the second filter seat 14 located below. When the lower end of the limit rod 44 is inserted into the limit groove 45, the clamping roller 41 is pressed against the filter belt 24.

[0025] When the lower end of the limiting rod 44 is plugged into the limiting groove 45, the position of the clamping frame 35 can be limited. When the clamping frame 35 needs to be rotated, it is only necessary to move the lower end of the limiting rod 44 out of the limiting groove 45, which is very convenient. The clamping frame 35 and the second filter seat 14 can cooperate with the limiting rod 44 to play a limiting role.

[0026] like Figure 3 and Figure 8 As shown, a second through hole 46 is formed on the second roller protrusion 21 , a second threaded hole 47 is formed on the bottom surface of the second mounting groove 18 , and a second connecting bolt 48 threadedly connected to the second threaded hole 47 is formed through the second through hole 46 .

[0028] like Figure 2As shown, the roller drive device includes a drive motor 49, which is fixed in the cabinet cavity 2. The rotating shaft 54 ​​of the drive motor 49 extends out of the cabinet cavity 2. A driving bevel gear 50 is fixed on the rotating shaft of the drive motor 49. A driven bevel gear 51 is fixed at one end of a first rotating shaft 8 extending out of the first filter seat 6, and the drive bevel gear 50 and the driven bevel gear 51 are meshed.

[0029] The rotating shaft 54 ​​of the driving motor 49 drives the driving bevel gear 50 to rotate, and the driving bevel gear 50 drives the driven bevel gear 51 to rotate, thereby driving the first winding roller 11 to rotate, thereby realizing winding.

[0030] like Figure 3 As shown, a side slot 52 is provided on the side wall of the limiting slot 43, and a side convex rod 53 extending out of the side slot 52 is fixed on the limiting rod 44. By moving the side convex rod 53, the upward movement of the limiting rod 44 can be facilitated.

[0031] The cabinet cavity 2 is also equipped with a temperature sensor. When the temperature sensor detects that the temperature in the cabinet cavity 2 is too high, the drive motor 49 rotates to replace the new filter belt 24. If the temperature in the cabinet cavity 2 does not drop to the expected temperature after replacement, the control cabinet will issue an alarm and call the maintenance personnel for maintenance. This can prevent the filter holes on the filter belt 24 from being blocked and affecting heat dissipation, and can also avoid frequent replacement of the filter belt 24 and waste of the filter belt 24.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
