[0002] In the field of electrical control, electrical control cabinets, as core equipment, undertake the important task of centrally installing and protecting internal electrical components. Traditionally, the internal components of electrical control cabinets are installed by assembling all components directly in a closed or semi-enclosed cabinet.

The upper end of the first circular connection frame 32 is fixedly connected to a rubber sealing ring 23, and cooperates with the second circular connection frame 16. Through this structure, during active heat dissipation, the flowing gas can more evenly contact the internal electrical components;

[0033] As an embodiment of the present invention, a rectangular opening 18 is provided on the rear side of the cabinet 1, and a rectangular slot 19 is provided on the upper end of the rear part of the cabinet 1. The rectangular slot 19 passes through the rectangular opening 18, and a sealing back plate 7 is placed in the slot. Limiting holes 20 are provided on the left and right sides of the sealing back plate 7, and through-openings 22 are provided on the inner walls of the left and right sides of the rectangular slot 19. The two U-shaped rods 21 are fixedly connected to the opposite sides with U-shaped rods 21. The front horizontal parts of the two U-shaped rods 21 pass through the inner wall of the cabinet 1, and the rear horizontal parts of the two U-shaped rods 21 pass through the corresponding through-openings 22 and extend to the inside of the limiting holes 20. During the installation operation, after the sealing back plate 7 is placed in the cabinet 1 and the electrical components on it are wired, the sealing back plate 7 is installed. There is a wire opening on the sealing back plate 7 to ensure that the wires can pass through. Finally, the limiting mechanism is started to limit the inner frame module and the sealing back plate 7.

[0034] In the present invention, the operator first installs the electrical components on the inner frame module, that is, on the mounting plate 26. In the initial state, the inner frame module is located on the outside. In this way, the operable space for the installation operation is increased.

[0035] After completing the installation of the electrical components on the inner frame module, the operator opens the sealed door 2 on the front side of the cabinet 1 and places the inner frame module with the installed electrical components into the cabinet 1. The lower end of the horizontal plate 24 at the bottom is symmetrically fixed with two bottom connecting strips 28, preparing for the subsequent limiting mechanism to limit the position of the inner frame module.

[0036] After the inner frame module is placed inside the cabinet 1, the operator performs wiring operations on the electrical components on the inner frame module. After the wiring is completed, the sealing back plate 7 is placed in the rectangular slot 19 on the rear side of the cabinet 1. The sealing back plate 7 is provided with a wire opening to ensure that the wires can pass through;

[0037] The drive motor 9 is started, and the drive motor 9 drives the bidirectional threaded rod 10 to rotate. Since the two threaded ends of the bidirectional threaded rod 10 have opposite thread directions, the two sliders 11 will move towards each other on the bidirectional threaded rod 10; the limit plugs 12 fixedly connected to the opposite sides of the upper ends of the two sliders 11 move accordingly and are inserted into the limit openings 29 provided on the opposite sides of the two bottom connecting bars 28 and cooperating with the limit plugs 12, thereby limiting the position of the inner frame module;

[0038] At the same time, the two U-shaped rods 21 will also move synchronously, until their rear horizontal portions penetrate the corresponding through openings 22 and extend into the interior of the limiting holes 20, thereby limiting the sealing back plate 7;

[0039] During the use of the control cabinet, the cooling fan 15 can be started for active heat dissipation. When the cooling fan 15 is started, external air enters the mounting tube 5 through the filter 6, and then enters the second circular connecting frame 16 through the connecting port 13; at this time, the rubber sealing ring 23 at the upper end of the first circular connecting frame 32 fixedly connected to the upper end of the upper horizontal plate 24 cooperates with the second circular connecting frame 16 to ensure sealing; after the gas enters the first circular connecting frame 32, it flows into the hollow plate 30 connected to its inner bottom, and then blows evenly to the internal electrical components through the multiple diversion holes 31 on the inner walls on the left and right sides of the hollow plate 30, taking away the heat generated by the electrical components, and finally the heat is dissipated to the outside of the cabinet 1 through the heat dissipation holes 3, ensuring the purpose of uniform heat dissipation and improving the actual service life.
