Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically to a frame structure for a power distribution cabinet. Background Technology

[0002] Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes). They are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits. Motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy of a certain circuit of the previous level of power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load. The metal frame and foundation steel of the distribution cabinet serve as the support and fixing structure for the electrical equipment. Their connection with the protective conductor is crucial. This connection must not only ensure the stable operation of the electrical equipment but also prevent injury to personnel due to electrical equipment failure.

[0003] In existing technologies, electrical components inside distribution cabinets are typically fixedly mounted on a rigid frame, which is rigidly connected to the cabinet body. This design has significant drawbacks in actual maintenance. When it is necessary to repair electrical components on the frame, maintenance personnel face two operational dilemmas: either they must completely disassemble the target component and move it outside the cabinet for repair, involving complex wiring disassembly and reassembly debugging, or they must extend their upper body into the narrow cabinet space to perform in-situ operations, which poses a risk of limb entrapment and does not comply with safe operating procedures. In addition, the mechanical vibration caused by frequent disassembly and assembly may accelerate the loosening of component pins, posing a hidden quality risk. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a frame structure for a power distribution cabinet, which solves the problems of power distribution cabinets.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A frame structure for a power distribution cabinet includes a cabinet 1. Two hinges are fixedly installed on each side of the cabinet 1. Cabinet doors 2 are provided on each side of the cabinet 1 and are connected to the cabinet 1 via hinges. Several support frames 3 are provided inside the cabinet 1. Support columns 4 are provided inside the cabinet 1 and pass through the several support frames 3. A pad 8 is provided on the bottom surface of the cabinet 1. Several L-shaped plates 5 are fixedly installed on each side of the inside of the cabinet 1. A baffle 26 is fixedly installed inside the L-shaped plate 5. A sliding component is provided on the bottom surface of the inside of the L-shaped plate 5. Several heat dissipation holes 9 are provided on each side of the cabinet 1.

[0027] With the support frame 3 in place, when repairing or replacing electrical components inside the enclosure 1, the support frame 3 is moved first, causing the support column 4 and chuck 6 to move. At this time, the chuck 6 will slide on the guide column 10. Then, the chuck 6 is slid to the opening of the enclosure 1, so that the support frame 3 and chuck 6 can be moved out of the enclosure 1. Since the electrical components inside the enclosure 1 are installed on the surface of the support frame 3, after the support frame 3 is moved out of the enclosure 1, the staff can directly repair the electrical components without having to lean into the enclosure 1. This facilitates the staff to conduct a comprehensive inspection of the electrical components installed on the support frame 3 and prevents the staff from touching the electrical components inside the enclosure 1 due to the narrow space inside the enclosure 1, which could lead to danger.

[0028] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 The sliding assembly includes several guide posts 10, which are fixedly installed on the inner bottom surfaces of several L-shaped plates 5. Several chucks 6 are respectively provided on both sides of the inner surface of the housing 1. A slide table 11 is fixedly installed on the inner top surface of the chuck 6. The guide posts 10 are slidably connected to the slide table 11. The L-shaped plates 5 are slidably connected to the chuck 6. The support frame 3 is fixedly installed on the chuck 6. A threaded hole is opened on the inner bottom surface of the chuck 6. A threaded post 13 is provided on the bottom surface of the chuck 6. A clamping block 12 is provided inside the chuck 6. The threaded post 13 is threadedly connected to the threaded hole. The threaded post 13 and the clamping block 12 are movably sleeved. Two slide rails 27 are fixedly installed on the inner bottom surface of the housing 1. Two slide tables 19 are fixedly installed on the bottom surface of the pad 8. The slide rails 27 and the slide tables 19 are slidably connected.

[0029] With the chuck 6 in place, when the operator moves the chuck 6 by moving the support frame 3, the chuck 6 will cause the slide table 11 to slide on the guide column 10, pushing the threaded column 13 to make the clamping block 12 be on the bottom surface of the L-shaped plate 5. The threaded column 13 is rotated to connect with the threaded hole on the inner bottom surface of the chuck 6. The chuck 6 and the clamping block 12 generate resistance against the guide column 10, which can fix the chuck 6 and the guide column 10, thereby fixing the position of the support frame 3 and preventing the electrical components installed on the support frame 3 from shaking in the housing 1. Moving the support frame 3 will cause the support column 4 and the movable ring 7 to move, and then the support frame 3 will cause the pad 8 and the slide table 19 to move parallel on the slide rail 27, which can avoid friction between the movable ring 7 and the inner bottom surface of the housing 1.

[0030] refer to Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8A disc 14 is fixedly installed on the bottom surface of the support column 4, and a movable ring 7 is fixedly installed on the top surface of the pad 8. The movable ring 7 is movably connected to the disc 14. Several resistance blocks 16 are fixedly installed on the outer circular wall of the support column 4, and a positioning post 15 is fixedly installed on the top surface of the resistance block 16. Several rectangular grooves are opened on the inner circular wall of the movable ring 7. A spring 25 is fixedly installed on one side of the inner side of the rectangular groove. A slider 17 is fixedly connected to one end of the spring 25. The slider 17 is movably connected to the rectangular groove. A positioning post 15 is fixedly installed on the top surface of the movable ring 7. The top surface of the plate 18 is provided with a circular through hole. Two limit blocks 23 are fixedly installed on the inner circular wall of the circular through hole. An adjusting column 20 is movably sleeved on the inner circular wall of the circular through hole. Two rectangular holes 21 are provided on the outer circular wall of the adjusting column 20. The rectangular holes 21 are slidably connected to the limit blocks 23. A snap-fit ​​shell 24 is fixedly installed on the bottom surface of the adjusting column 20. The snap-fit ​​shell 24 is movably snap-fitted to the positioning column 15. The outer circular wall of the adjusting column 20 is threaded and a nut 22 is threadedly connected to the outer circular wall of the adjusting column 20.

[0031] By rotating the support column 4, the positioning column 15 and the resistance block 16 are driven to rotate. When the positioning column 15 is inserted into the inside of the snap-fit ​​shell 24, the rectangular hole 21 slides on both sides of the outside of the limit block 23, so that the positioning column 15 is at the bottom of the adjusting column 20. The rotating nut 22 is threadedly connected to the outer circular wall of the adjusting column 20 to fix the position of the positioning column 15, thereby increasing the fastening effect on the support column 4.

[0032] Working principle: Please refer to Figures 1-8 As shown, with the support frame 3 in place, when repairing or replacing electrical components inside the enclosure 1, the support frame 3 is moved first, causing the support column 4 and chuck 6 to move. At this time, the chuck 6 will slide on the guide column 10. Then, the chuck 6 is slid to the opening of the enclosure 1, so that the support frame 3 and chuck 6 can be moved out of the enclosure 1. Since the electrical components inside the enclosure 1 are installed on the surface of the support frame 3, after the support frame 3 is moved out of the enclosure 1, the staff can directly repair the electrical components without having to lean into the enclosure 1. This facilitates the staff to conduct a comprehensive inspection of the electrical components installed on the support frame 3 and prevents the staff from touching the electrical components inside the enclosure 1 due to the narrow space inside the enclosure 1, which could lead to danger.

[0033] When the worker places the support frame 3 and the pad 8 into the housing 1 using the chuck 6, the chuck 6 and the slide 11 are moved by moving the support frame 3. This causes the slide 11 to enter the L-shaped plate 5 and slide on the guide post 10. Then, the support frame 3 and the support post 4 are pushed, causing the chuck 6, the slide 11, and the pad 8 to move, thus pushing the support frame 3, the support post 4, and the pad 8 into the housing 1 for placement. Subsequently, the worker tightens the threaded post 13, and because the clamping block 12 is in the L-shape... When the threaded column 13 rotates, it pushes the clamping block 12 upward, which in turn brings the clamping block 12 closer to the bottom of the L-shaped plate 5. Then, the threaded column 13 is tightened, so that the clamping block 12 is pressed against the bottom of the L-shaped plate 5 and generates resistance between the clamping block 12 and the L-shaped plate 5. This facilitates the restriction of the chuck 6 and the slide table 11, and at the same time, it can stabilize the support frame 3 and the support column 4, preventing the support frame 3 from moving when placed inside the housing 1. Through the above operations, it is easy to put the repaired electrical components on the support frame 3 back into the housing 1 and restrict their position.

[0034] With the disc 14 in place, when the staff moves the support frame 3, support column 4 and pad 8 out of the box 1, the movable ring 7 and disc 14 will follow the movable ring 7 and support column 4 out of the box 1. Then, the staff can rotate the support frame 3 and support column 4 to drive the disc 14 to rotate, which makes it easier to rotate and adjust the position and orientation of the support frame 3 and the electrical components installed on the support frame 3, so as to inspect and replace the electrical components in different directions.

[0035] When the disc 14 rotates inside the movable ring 7, the surface of the disc 14 will contact the surface of the slider 17. Since the slider 17 is held in place by the spring 25, one side of the slider 17 will be in close contact with the outer surface of the disc 14. At this time, the disc 14 rotates in close contact with the surface of the slider 17, thereby increasing the frictional resistance when the disc 14 rotates. This prevents the disc 14 from causing the support frame 3 and support column 4 to rotate flexibly when the staff is repairing the electrical components installed on the support frame 3, which would require the staff to frequently correct the position of the support frame 3.

[0036] When workers install electrical components on the support frame 3 using the nut 22, it is necessary to restrict the support frame 3 and the support column 4 to prevent them from shaking during the installation process. By rotating the nut 22 clockwise, the adjusting column 20 is limited by the limiting block 23. When the nut 22 rotates clockwise, it will cause the adjusting column 20 to move the locking shell 24 downward. As the locking shell 24 moves downward, it will approach the resistance block 16, allowing the positioning column 15 to enter the interior of the locking shell 24. This facilitates the restriction of the resistance block 16, the disc 14, the support column 4, and the support frame 3, increasing the stability of the support frame 3 and preventing it from shaking when electrical components are installed on it.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
