The top plate 4 is provided with a mounting port 12, and an exhaust fan 13 is installed in the mounting port 12. The upper end of the base 2 is covered with a bottom plate 14, and the bottom plate 14 is provided with a plurality of air holes and a plurality of wiring ports. The base 2 is provided with a plurality of air holes 15 around. The mask plate 5 is movably provided with a plurality of columns 16 around, and the upper ends of the columns 16 are respectively provided with bells 17. The middle of the raised line 7 is fixedly connected with a central axis 18, and a rotatable sleeve on the central axis 18 is provided. A rotating tube 19, the lower end of which extends into the heat dissipation space 6 and is driven to rotate by the working shaft of the exhaust fan 13. The portion of the rotating tube 19 located outside the heat dissipation space 6 is fixedly connected to a horizontally arranged swing rod 20. The rotating tube 19 rotates to drive the swing rod 20 to knock on the column 16 in sequence. The upper end height of the central axis 18 is higher than the height of the bell 17. The lower end of the central axis 18 is grounded through a grounding wire. The central axis 18 is made of a conductive material. There are multiple bases 2, and the multiple bases 2 are arranged in sequence from bottom to top. Adjacent bases 2 are fixedly connected by a number of bolts, and the bottom plate 14 covers the top. The upper end of a base 2 and the lower end of the box body are detachably connected to the upper end of the top base 2. The front of the base 2 is provided with an installation port 12 connected to the inside of the base 2. A footrest 24 is installed in the installation port 12 through a drawer slide rail 27. A cover plate 25 is fixedly connected to the footrest 24, and a handle 26 is fixedly connected to the cover plate 25. The cover plate 25 of the bottom base 2 is connected to the corresponding base 2 through a lock. Except for the cover plate 25 on the top base 2, the upper ends of the other cover plates 25 are fixedly connected with a baffle 30, and the upper end of the baffle 30 blocks the lower side of the previous cover plate 25. The number of bases 2 is determined according to the use site of the low-voltage control cabinet. Multiple bases 2 can raise the height of the cabinet 1 to prevent the low-voltage control cabinet from being affected by floods, animals, etc. At the same time, the space under the cabinet 1 is increased, the heat dissipation effect is improved, and the influence of the surface temperature is reduced. The footrest 24 can be pulled out to a certain length by the handle 26. The pedal racks 24 are pulled out to different lengths to form steps, which facilitates maintenance personnel to enter the control cabinet to perform related operations. The bottom pedal rack 24 is connected to the base 2 through a lock and cannot be pulled out at will. The baffle 30 is used to lock all the pedal racks 24 above in turn, thereby improving the safety of the pedal racks 24.When not in use, push the pedal frame 24 back into the base 2 to prevent people or animals from directly contacting the cabinet 1. In addition to improving the heat dissipation effect in the cabinet 1, the exhaust fan 13 can also drive the rotating tube 19 to rotate, and use the swing rod 20 to knock the column 16 to drive the bell 17 to make a sound, which is used to drive away birds and other animals. The continuously rotating swing rod 20 can prevent birds from staying on the mask plate 5 and prevent birds from building nests on the mask plate 5. The air vents around the base 2 take in air, and compared with the traditional method of opening air holes on the cabinet 1, the interior of the cabinet 1 is not easily affected by rain. At the same time, it is not easy for flying insects to directly enter the cabinet 1 and contact electrical components. The central axis 18 also acts as a lightning rod. The bell can use a regular bell, and the sound can be made by physical vibration. The sound is pleasant and will not form a strong noise.

[0015] Further, the lower end of the column 16 is connected to the mask plate 5 through a spring 21. The spring 21 allows the column 16 to shake after being struck by the swing rod 20, thereby driving the bell 17 to make a sound.

[0016] Furthermore, the exhaust fan 13 is a low-power exhaust fan 13, and the exhaust fan 13 is powered by a power supply in the control cabinet. The low-power exhaust fan 13 has low power consumption.

[0017] Furthermore, the lower end of the central shaft 18 is fixedly connected to the top plate 4, and the lower end of the rotating tube 19 is fixedly connected to a large gear 22, which is meshed with a small gear 23, and the small gear 23 is fixedly connected to the output shaft of the exhaust fan 13. The cooperation between the large gear 22 and the small gear 23 can reduce the rotation speed of the rotating tube 19.

[0018] Furthermore, the cabinet body 1 includes a cabinet door, and an observation window made of a transparent material is installed on the cabinet door.

[0019] It is worth mentioning that the technical features such as exhaust fans and bells involved in the patent application of this invention should be regarded as prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected according to the conventional methods in the field, and should not be regarded as the inventive point of this patent. This patent will not be further elaborated.

[0020] The preferred specific embodiments of the present invention are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the present invention without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the existing technology should be within the scope of protection determined by the claims.
