[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final equipment of the power distribution system. Distribution cabinets are the general term for motor control centers. Distribution cabinets are used in occasions where the load is relatively scattered and the number of circuits is small; motor control centers are used in occasions where the load is concentrated and the number of circuits is large. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby loads, and this level of equipment should provide protection, monitoring, and control for the loads.

[0003] The prior art discloses an assembled high and low voltage distribution cabinet (application number 202221222026.7), which includes a bottom cabinet. Multiple middle cabinets and a top cabinet are sequentially arranged on the top of the bottom cabinet.

The number of cabinet bodies 10 can be selected according to actual operation requirements, so that the volume of the power distribution cabinet can be expanded or reduced. The exhaust device inside the top cabinet 12 can discharge the hot air inside the multiple groups of cabinet bodies 10 to the outside. Second filter screens 25 are arranged on the outer walls on the left and right sides of each cabinet body 10. The setting of the second filter screens 25 can achieve ventilation and heat dissipation, ensuring that air can circulate normally.

[0034] As Figure 2 、 Figure 4As shown in the figure, the rainproof device includes a sunshade 14, which is in an inverted V shape. Connecting brackets 13 are fixedly provided on the outer walls of the tops of both sides of the top cabinet 12. The other ends of the two connecting brackets 13 are fixedly connected to the sunshade 14. The upper and lower ends of the top cabinet 12 are in a hollow state, and the sunshade 14 completely covers the top cabinet 12. A first filter screen 15 is also fixedly provided on the top of the top cabinet 12. The exhaust device includes an exhaust fan, and the exhaust fan is fixedly installed in the middle of the cavity of the top cabinet 12 through a bracket.

[0035] As Figure 2 , Figure 3 , Figure 6 shown in the figure, the assembly structure includes connecting plates 20 fixedly provided on the outer wall of the bottom of the top cabinet 12 and the outer wall of the bottom of the cabinet body 10. The connecting plate 20 is in a concave shape with an opening facing the front side. The assembly structure also includes a limiting plate 23 fixedly provided on the upper side of the outer wall of the top of the cabinet body 10. The cross-section of the limiting plate 23 is in an L shape, and the position of the limiting plate 23 corresponds to the position of the connecting plate 20 up and down. An insertion channel is opened at the bottom of the connecting plate 20, and the vertical end of the limiting plate 23 is inserted into the insertion channel at the bottom of the connecting plate 20. A plurality of fixing bolts 24 pass through the limiting plate 23 movably. The fixing bolts 24 penetrate through the vertical part of the limiting plate 23. Threaded holes corresponding to the positions of the fixing bolts 24 are opened on the inner wall of the insertion channel of the connecting plate 20, and the top ends of the fixing bolts 24 are rotationally screwed into the threaded holes. The assembly structure also includes insertion plates 21 fixedly provided on the top wall surfaces of each cabinet body 10. The cross-section of the insertion plate 21 is triangular, and insertion slots 22 that cooperate with the insertion plates 21 up and down are opened at the bottoms of the cabinet body 10 and the top cabinet 12.

[0036] As Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, on the outer walls of the left and right sides of the connecting plate 20, there are also provided shielding structures for shielding the second filter screen 25 below from wind and rain. The shielding structure includes a mounting plate 30 fixedly arranged perpendicular to the outer wall of the connecting plate 20. The bottom end of the mounting plate 30 is rotatably connected with a shielding plate 31 whose unfolding angle can be adjusted. On the side wall surface of each shielding plate 31 close to the corresponding second filter screen 25 below, there are movably arranged two support rods 32, and the other ends of the support rods 32 are limited on the outer wall of the cabinet body 10. On the inner wall of each shielding plate 31, there are provided two front and rear storage grooves 34. In the inner wall below the storage groove 34, there is rotatably installed a rotating rod 35. One end of the support rod 32 is fixedly arranged together with the rotating rod 35. A permanent magnet is also fixedly arranged in the inner wall of the storage groove 34. A permanent magnet is also fixedly arranged on the side wall surface of the support rod 32 close to the storage groove 34. Through the two permanent magnets that can attract each other magnetically, the support rod 32 can be stored in the storage groove 34. When using the support rod 32, just flip the support rod 32 out; on the outer walls of the left and right sides of each cabinet body 10, there are provided two groups of front and rear tooth grooves 33. In each tooth groove 33, there are fixedly arranged tooth blocks distributed at equal intervals. The other end of the support rod 32 is clamped between two adjacent tooth blocks.

[0037] When assembling and installing multiple cabinet bodies 10 up and down, first align the connecting plate 20 at the bottom of the upper cabinet body 10 with the limiting plate 23 on the lower cabinet body 10. At the same time, the plug-in plate 21 on the lower cabinet body 10 will also be inserted into the slot 22 at the bottom of the upper cabinet body 10. In this way, double locking of the upper and lower two cabinet bodies 10 can be realized. After the upper and lower two cabinet bodies 10 are stacked and aligned, through the fixing bolt 24 on the lower limiting plate 23, rotate and screw in the fixing bolt 24, and the limiting plate 23 can be fixed together with the connecting plate 20, and the fixing of the upper and lower two cabinet bodies 10 can be realized. Then, according to the same operation, continue to stack the cabinet bodies 10 and fix them. Finally, stack the top cabinet 12 at the uppermost side onto the cabinet body 10 at the topmost, and also fix it according to the same operation.

[0038] It should be noted that, in addition to the breathable partition 16 that can be fixedly installed on the bottom inner wall of the lowermost cabinet body 10, a sealing plate can also be fixedly installed. The reason is that the lowermost cabinet body 10 is located on the ground. In order to prevent moisture from entering the lowermost cabinet body 10, a sealing plate can be fixedly installed to seal the bottom of the lowermost cabinet body 10. In other cabinet bodies 10, a breathable partition 16 can be selected for use. The electrical equipment is fixedly installed on the corresponding breathable partition 16 or on the inner wall of the cabinet body 10. A number of groups of ventilation holes are provided on the breathable partition 16 to allow normal ventilation between the upper and lower cabinet bodies 10. In this way, when the exhaust fan is working, the air in the lower cabinet body 10 can be sucked upward and discharged, and the second filter screen 25 on the cabinet body 10 can allow the air to enter the cabinet body 10 normally, so as to realize normal ventilation and heat dissipation of multiple cabinet bodies 10.

[0039] By providing a shielding structure on the connecting plate 20 for shielding the lower second filter screen 25 from wind and rain, the shielding plate 31 rotates through two support rods 32, and one end of the support rod 32 is inserted into the tooth groove 33, so as to realize the flipping support of the shielding plate 31. The shielding plate 31 in an inclined state can shade, shield the wind and rain for the second filter screen 25, prevent rainwater from entering the cabinet body 10, and the shielding angle of the shielding plate 31 can be adjusted according to the size of sunlight or rainfall. It only needs to rotate the support rod 32 and insert it into the tooth groove 33 at an appropriate height, which is more convenient to use.
