[0041] As shown in Figures 1 to 5 In an embodiment, an AC low-voltage power distribution cabinet 1 with modular intelligent control and heat dissipation performance includes a box body 10 and a plurality of module assemblies 20. The box body 10 is provided with a control chamber and a module chamber 11. The control chamber and the module chamber 11 are in communication with each other. The box body 10 is provided with a plurality of heat dissipation members 294. Each heat dissipation member 294 is located in the control chamber and the module chamber 11. Each module assembly 20 is slidingly arranged in the module chamber 11, and the module assemblies 20 are spaced apart. The module assembly 20 includes a frame 21, a hanging rail 22, a hook seat 23, a supporting rail 24, a supporting seat 25 and a supporting member 26. The hanging rail 22 and the supporting rail 24 are arranged on the box body 10. The hook seat 23 and the supporting seat 25 are arranged at opposite ends of the frame 21. The hook seat 23 is slidingly connected with the hanging rail 22, and the supporting rail 24 is slidingly connected with the supporting seat 25, so that the frame 21 slides out of the module chamber 11. The frame 21 is provided with a plurality of horizontal plates 211, and the horizontal plates 211 are equally spaced. Each horizontal plate 211 is used for mounting electrical elements.

[0042] It should be noted that the control chamber is provided with electrical components, for example, the control chamber is provided with line relay, disconnecting switch, branch switch, leakage protector, ammeter, voltmeter, indicator light, terminal block and the like. Further, the plurality of module assemblies 20 are arranged in the module chamber 11 in a transverse sliding manner, and the plurality of module assemblies 20 are equidistantly distributed in the module chamber 11. The module assembly 20 comprises a frame 21, a hanging rail 22, a hook base 23, a supporting rail 24, a supporting base 25 and a supporting member 26. The frame 21 tends to be a rectangular structure. The hanging rail 22 is arranged on the box body 10 and located above the module chamber 11. The supporting rail 24 is arranged on the box body 10 and located below the module chamber 11, and the supporting rail 24 is aligned with the hanging rail 22. Further, the hook base 23 and the supporting base 25 are arranged on the two opposite sides of the frame 21 respectively, and the hook base 23 is connected with the hanging rail 22, and the supporting base 25 is connected with the supporting rail 24. One end of the hanging rail 22 is directed to the inner bottom wall of the module chamber 11, and the other end of the hanging rail 22 is directed to the opening of the module chamber 11. One end of the supporting rail 24 is directed to the inner bottom wall of the module chamber 11, and the other end of the supporting rail 24 is directed to the opening of the module chamber 11. Therefore, the frame 21 can be slid out of or into the module chamber 11 relative to the box body 10. In this way, the plurality of module assemblies 20 can be individually slid out of the module chamber 11 for installation or maintenance operation by maintenance personnel. Further, a plurality of horizontal plates 211 are arranged on the frame 21, and the two ends of each horizontal plate 211 are connected with the inner side walls of the two opposite sides of the frame 21 respectively, and the plurality of horizontal plates 211 are equidistantly distributed, and each horizontal plate 211 is used for mounting various electrical components. Further, the electrical components on each horizontal plate 211 are electrically connected with the electrical components in the control chamber, so that the electrical components in the control chamber can control the plurality of module assemblies 20 simultaneously to realize intelligent control.

[0043] It should be noted that the hanging rail 22 is provided with a T-shaped block extending from one end to the other end of the hanging rail 22. The hook base 23 is provided with a T-shaped slot extending from one end to the other end of the hook base 23. The T-shaped block is connected with the T-shaped slot, so that the hook base 23 can drive the frame 21 to slide along the extending direction of the T-shaped block. Further, the supporting rail 24 is provided with an H-shaped block extending from one end to the other end of the supporting rail 24. The supporting base 25 is provided with a U-shaped slot extending from one end to the other end of the supporting base 25. The H-shaped block is inserted into the U-shaped slot, so that the hook base 23 and the supporting base 25 jointly drive the frame 21 to slide along the extending directions of the T-shaped block and the H-shaped block respectively, thereby enabling the frame 21 to slide out of or into the module chamber 11 relative to the box body 10.

[0044] It should be noted that the module assembly 20 further comprises a track wire groove 27, one end of the track wire groove 27 is arranged in the end of the frame body away from the inner bottom wall of the module chamber 11, and the other end of the track wire groove 27 is arranged in the incoming wire box 10. In this way, the electrical elements in the incoming wire box 10 can be electrically connected with the electrical elements on each module assembly 20 through the track wire groove 27.

[0045] As shown in Figures 4 to 5 , in an embodiment, the module assembly 20 further comprises a partition plate 28 arranged on the frame 21.

[0046] It should be noted that the partition plate 28 is arranged on one side surface of the frame 21, so that the frame 21 and the partition plate 28 together form a frame 21 with a groove 2612. When each frame 21 is slid in the module chamber 11 at intervals, one side surface of one frame 21 is communicated with one side surface of another frame 21, so as to avoid the wires on the electrical elements of the two frames 21 from being in contact with each other during sliding when the maintenance personnel frequently slide the frame 21, thereby causing the connection points of the wires and the electrical elements to be loose, or the wires on one frame 21 are pulled by the electrical elements on another frame 21, thereby causing the wires to fall off. Further, a plurality of through holes are formed in the partition plate 28 to increase the air flow in the single module assembly 20, thereby reducing the temperature in the single module assembly 20.

[0047] As shown in Figure 5 , in an embodiment, the module assembly 20 further comprises a sliding member 29, one end of the sliding member 29 is arranged on the supporting rail 24, and the other end of the sliding member 29 is in abutment with the bearing 25.

[0048] It should be noted that the sliding member 29 comprises a sliding seat 291 and a pulley 292, the sliding seat 291 is arranged on the supporting rail 24, and the pulley 292 is rotatably arranged on the sliding seat 291. The sliding seat 291 is arranged on the supporting rail 24, and the sliding seat 291 is located on the inner side wall of the H-shaped block, so that the sliding seat 291 is located between the supporting rail 24 and the bearing 25. Further, the pulley 292 is rotatably arranged on the sliding seat 291, and the pulley 292 is in abutment with the inner bottom wall of the U-shaped groove on the bearing 25, so that the frame 21 can smoothly slide in the U-shaped groove.

[0049] As shown in Figures 6 to 14 , in an embodiment, the supporting member 26 comprises a supporting rod 261, a locking ring 262, and a plurality of claw blocks 263, one end of the supporting rod 261 is rotatably arranged on the frame 21, the locking ring 262 is sleeved on the supporting rod 261, one end of each of the claw blocks 263 is rotatably arranged on the supporting rod 261, and the other end of each of the claw blocks 263 is rotatably connected with the locking ring 262. The locking ring 262 drives the claw blocks 263 to be spread apart relative to one end of the supporting rod 261, so that the claw blocks 263 and the supporting rod 261 together support the frame 21.

[0050] It is to be noted that the two sides of one end of the supporting rod 261 are rotatably connected with the supporting rail 24 and the frame 21, so that the supporting rod 261 can swing relative to the frame 21. Further, the one end of the supporting rod 261 is away from the end of the supporting rail 24 and the frame 21 which is away from the inner bottom wall of the module chamber 11, and the other end of the supporting rod 261 is accommodated between the supporting rail 24 and the frame 21. When the frame 21 drives the supporting rod 261 to slide out of the module chamber 11, the supporting rod 261 can swing relative to the frame 21 to support the frame 21 by the end of the supporting rod 261 which is away from the frame 21. Further, the locking ring 262 comprises a ring block 2621, a ring seat 2622 and a plurality of push blocks 2623. The end of the supporting rod 261 away from the frame 21 is provided with a plurality of guide grooves 2611, each of which is formed along the axial direction of the supporting rod 261 and extends inward from the end of the supporting rod 261 away from the frame 21. One end of each claw block 263 is rotatably connected with the end of the supporting rod 261, and the other end of each claw block 263 is rotatably accommodated in each guide groove 2611. The side surface of the ring seat 2622 is provided with a plurality of clamping pieces 26221, which are equidistantly distributed along the circumferential direction of the ring seat 2622. When the ring seat 2622 is sleeved on the supporting rod 261, each clamping piece 26221 is correspondingly located in each guide groove 2611, so that the ring seat 2622 can slide along the axial direction of the supporting rod 261. Further, each push block 2623 is correspondingly located in each guide groove 2611, and one end of each push block 2623 is connected with each clamping piece 26221, and the other end of each push block 2623 is in U-shaped structure, and the U-shaped structure of each push block 2623 is slidably connected with each claw block 263. Specifically, the inner side walls of the U-shaped structure of each push block 2623 are provided with clamping columns 26231 on the two sides facing each other, and the two side surfaces of each claw block 263 are provided with inclined sliding grooves 2631, for example, the two ends of each inclined sliding groove 2631 are located at the opposite corners of the side surface of the claw block 263. Two clamping columns 26231 are respectively connected with two inclined sliding grooves 2631. When the ring seat 2622 drives each push block 2623 to approach the connection position of each claw block 263 and the end of the supporting rod 261, each push block 2623 will drive each clamping column 26231 to slide along the inclined sliding groove 2631 from the upper right corner of the side surface of the claw block 263 to the lower left corner of the side surface of the claw block 263, so that each claw block 263 is accommodated in the end of the guide groove 2611 and extends out of the guide groove 2611. In this way, when the supporting rod 261 swings relative to the frame 21 to support the frame 21, the ring seat 2622 slides close to the end of the supporting rod 261 away from the frame 21, so that each claw block 263 can open relative to the end of the supporting rod 261 to jointly support the frame 21 and improve the stability of the support.

[0051] It should be noted that the two sides of the rail 24 are provided with side wings 251, the side wings 251 are respectively from one end of the rail 24 to the other end, and the end portions of the side wings 251 close to the two ends of the rail 251 are arc-shaped structures, so that when the frame 21 slides into the module cavity 11 relative to the box 10, the support 26 driven by the frame 21 slides along the side wings 251 away from the end of the frame 21, so that the support 26 is parallel to the end of the frame 21 and the support 26 is accommodated in the frame 21.

[0052] It should be noted that the two opposite outer sides of the U-shaped structure of each push block 2623 are respectively provided with guide columns 26232, and the support rod 261 is also provided with a plurality of recesses 2612. Each guide groove 2611 has a recess 2612 on the inner side wall facing each other. The direction of each recess 2612 is consistent with the direction of each guide groove 2611. Each guide column 26232 is one-to-one corresponding to each recess 2612 and is clamped, so that when the ring seat 2622 drives each push block 2623 to slide in each guide groove 2611, each push block 2623 can slide along the direction of the guide groove 2611.

[0053] As shown in Figures 6 to 9 In an embodiment, the support rod 261 is provided with an adjusting groove 2613, and the ring block 2621 is provided with a convex column 26211, which is clamped with the adjusting groove 2613.

[0054] It needs to be explained that the end of the supporting rod 261 away from the frame 21 is provided with a plurality of adjusting grooves 2613, and each adjusting groove 2613 is equidistantly distributed along the circumferential direction of the supporting rod 261. It needs to be noted that the two ends of the adjusting groove 2613 are respectively provided with clamping portions, and the two clamping portions are in communication with the adjusting groove 2613 and perpendicular to the adjusting groove 2613. Further, the circumferential surface of the end of the ring seat 2622 away from the clamping block 26221 is provided with a ring groove, and the inner side wall of the ring block 2621 is provided with a clamping table in a circular ring shape at one end. The clamping table is clamped with the ring groove, so that the ring block 2621 can rotate with the axis of the ring seat 2622 as the center. Further, the inner side wall of the ring block 2621 is provided with a plurality of protruding columns 26211 at the end away from the clamping table, and each protruding column 26211 is one-to-one corresponding to each adjusting groove 2613. When the ring seat 2622 drives each push block 2623 to push the claw block 263, the ring seat 2622 also drives each protruding column 26211 on the ring block 2621 to slide along each adjusting groove 2613. When each protruding column 26211 slides to the end of each adjusting groove 2613, the ring block 2621 is rotated to make each protruding column 26211 slide from the adjusting groove 2613 to the clamping portion, so that the ring seat 2622 cannot drive each push block 2623 to slide in each guide groove 2611. In this way, each push block 2623 pushes each claw block 263 to expand relative to the end of the supporting rod 261 and cannot be retracted. When the ring block 2621 is rotated to make each protruding column 26211 slide from the clamping portion to the adjusting groove 2613, the ring seat 2622 can drive each protruding column 26211 on the ring block 2621 to slide from one end to the other end of the adjusting groove 2613, so that each push block 2623 on the ring seat 2622 drives each claw block 263 to be accommodated in the guide groove 2611.

[0055] As shown in the figure, Figures 4 to 5 In an embodiment, the module assembly 20 further comprises a plurality of limiting plates 293, each limiting plate 293 is arranged on one end of the frame 21, and the two ends of each limiting plate 293 respectively extend from the two opposite sides of the frame 21.

[0056] It needs to be explained that when the frame 21 is extended from the module cavity 11 relative to the box body 10, the two ends of each limiting plate 293 respectively abut against the box body 10, so that the frame 21 cannot completely fall off from the module cavity 11.

[0057] As shown in the figure, Figure 3As shown in the figure, in an embodiment, each heat dissipation member 294 is arranged on the regulating chamber and the module chamber 11, for example, the heat dissipation member 294 is a fan structure, and the distance between each heat dissipation member 294 is provided, specifically, one heat dissipation member 294 is arranged on the upper position of the back of the box 10, and the other heat dissipation member 294 is arranged on the lower position of the side of the box 10, one heat dissipation member 294 draws air into the box 10, and the other heat dissipation member 294 blows air into the box 10, so as to accelerate the air flow in the box 10, thereby reducing the temperature in the box 10.

[0058] As shown in the figure, Figure 1 , Figures 4 to 5 As shown in the figure, in an embodiment, the side of the frame 21 away from the module chamber 11 is provided with electrical elements, for example, the frame 21 is provided with a shunt switch, a leakage protector, an ammeter, a voltmeter and an indicator light, so that the maintenance personnel can operate and maintain the module assembly 20.

[0059] The above-mentioned embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application.
