Description

Technical Field

[0001] This utility model relates to the field of electrical control cabinets, and in particular to a novel explosion-proof electrical control cabinet. Background Technology

[0002] Explosion-proof electrical control cabinets were developed to address the issues of safe handling and storage. Most of them are modular in structure, with the outer shell made of cast aluminum alloy, some of which are made of welded carbon steel or stainless steel plates, and a small number of which have an insulating outer shell. The internal components mainly consist of electrical components such as circuit breakers, contactors, thermal relays, changeover switches, explosion-proof lights, and explosion-proof buttons.

[0003] The existing utility model patent with publication number CN 214069292 U discloses a novel explosion-proof electrical control cabinet. Through its buffer components, it effectively prevents damage to internal electrical equipment caused by collisions during transportation and movement, thus buffering the forces generated by external impacts and increasing the cabinet's cushioning capability. The heat dissipation components effectively prevent rainwater from flowing into the cabinet through the ventilation holes and causing short circuits in the internal electrical equipment, further enhancing its practicality. However, it lacks flexible relocation capabilities, making adjustments and installation inconvenient. Furthermore, it lacks the ability to organize and manage internal wiring harnesses, leading to inconvenience in later maintenance and repair. Therefore, we need to upgrade and modify the existing technology to overcome its problems and shortcomings. Utility Model Content

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1 As shown in Figure 4, this embodiment provides a novel explosion-proof electrical control cabinet, including a device body 1. The device body 1 contains a main cabinet 2 and a base plate 7. The main cabinet 2 has a cover plate 3 on the front and a support leg 6 at the bottom. The lower end of the main cabinet 2 is fixed with an upper hinge seat 8, and a movable rod 9 is rotatably provided on the inner side of the upper hinge seat 8. The lower ends of the movable rods 9 on both sides are rotatably installed with connecting shafts 11. The outer side of the base plate 7 is rotatably provided with a movable wheel 12, and both ends are fixed with side hinge seats 13. The inner side of the side hinge seat 13 is rotatably provided with a bidirectional screw 14, and both ends of the bidirectional screw 14 are provided with hand cranks 15. Two sets of connecting shafts 11 are screwed to the two sides of the bidirectional screw 14. Several sets of side slide rails 18 are provided on the inner wall of the main cabinet 2, and sliding blocks 19 are slidably provided in the side slide rails 18. A connecting column 20 is fixed on the outer side of the sliding block 19, and a wire threading plate 21 is connected to the outer side of the connecting column 20. Two sets of wire threading holes 22 are opened on the wire threading plate 21.

[0024] Preferably, the main cabinet 2 and the cover plate 3 are provided with a number of mounting holes 4, and explosion-proof bolts 5 are fixedly screwed into the mounting holes 4. The mounting holes 4 and the explosion-proof bolts 5 facilitate the disassembly and assembly of the cover plate 3, thus ensuring the explosion-proof performance of the main cabinet 2.

[0025] Preferably, both ends of the connecting shaft 11 are provided with movable blocks 10, which slide against the base plate 7. The movable blocks 10 facilitate auxiliary balancing and support of the connecting shaft 11. The base plate 7 is provided with four sets of guide sleeves 16, and the lower end of the main cabinet 2 is provided with four sets of guide rods 17, which correspond to the guide sleeves 16. The guide sleeves 16 and guide rods 17 work together to facilitate vertical guidance of the lifting and lowering of the main cabinet 2 and maintain its stability.

[0026] Preferably, the connecting post 20 is provided with a threaded hole 201, and the inner side of the wire guide plate 21 is provided with a bolt joint 211 and the bolt joint 211 is connected to the threaded hole 201. The connection between the threaded hole 201 and the bolt joint 211 facilitates the assembly and disassembly of the wire guide plate 21. A rubber sleeve 23 is provided in the wire guide hole 22 to facilitate the anti-friction protection of the wire harness.

[0027] The working principle and operation process of this utility model are as follows: When in use, the electrical equipment is installed inside the main cabinet 2. Several sliding blocks 19 are placed in the side slide rail 18, so that one side of the connecting column 20 faces the inside of the main cabinet 2. The wiring plate 21 is screwed onto the threaded hole 201 using bolt joints 211. At this time, the connecting wires of the electrical equipment can be passed through the rubber sleeve 23 in the wiring hole 22. Then, the wire harness is neatly arranged and positioned by moving the sliding blocks 19. The wiring plate 21 can be locked in place using bolt joints 211. Repeat the above operation until all electrical components inside the main cabinet 2 are arranged. Finally, the cover plate 3 is fixedly installed to the main cabinet 2 using the mounting holes 4 and explosion-proof bolts 5. When the device needs to be moved, the bidirectional screw 14 can be rotated by the hand crank 15. The bidirectional screw 14 pushes the two opposing connecting shafts 11 to move in opposite directions. The two sets of connecting shafts 11 push the upper movable rod 9 to rotate in opposite directions. The lower end of the movable rod 9 pushes the base plate 7 down through the connecting shaft 11 and makes the moving wheel 12 contact the ground. At this time, if the hand crank 15 is continued to be rotated, the base plate 7 will not be able to descend. The movable rod 9 will push the main cabinet 2 up through the upper hinge seat 8. When the support leg 6 is off the ground at the specified height, the device can be moved by the moving wheel 12. After the movement is completed, the hand crank 15 is reversed to reset the base plate 7 and retract it to the inside of the support leg 6.
