Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment, and specifically relates to an environmentally friendly gas ring main unit made of sheet metal splicing. Background Technology

[0002] Currently, the gas box of the ring main unit is mainly welded from stainless steel plates. It is difficult to maintain consistent weld dimensions, which leads to assembly errors in the sheet metal splicing of the whole unit. Furthermore, the sheet metal splicing of the ring main unit mainly involves the right-angle bend of the mechanical chamber sheet metal, with the bent surface overlapping the front of the gas box. Bolts are welded to the front of the gas box and fixed with nuts. This installation method results in direct contact between the gas box weld and the mechanical chamber sheet metal. The height of the gas box weld is inconsistent, leaving gaps at the splice. If the gas box weld is too high, the assembled cabinet dimensions will have larger assembly tolerances. When splicing with other cabinets, the concentricity of the concatenation holes will cause the bolt holes to be misaligned, making it impossible to pass bolts for fixing and causing difficulties in concatenation.

[0003] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this utility model was created to provide an environmentally friendly gas ring network cabinet with sheet metal splicing to solve the problem. Utility Model Content

[0004] This utility model proposes an environmentally friendly gas ring main unit with sheet metal splicing, which solves the problem in the prior art that the weld height of the ring main unit is inconsistent, resulting in large assembly tolerance of the assembled cabinet size, and the cabinet hole is not concentric when splicing with other cabinets, making it impossible to pass bolts for fixing, which causes difficulties in cabinet splicing.

[0005] The technical solution of this utility model is implemented as follows: A sheet metal splicing environmentally friendly gas ring main unit includes: a gas box assembly, a control room assembly, a mechanism room assembly, and a cable room assembly. One side of the gas box assembly is connected to the mechanism room assembly by connecting bolts. The control room assembly is installed on the upper part of the mechanism room assembly. The cable room assembly is installed on the lower part of the gas box assembly and the mechanism room assembly. Positioning and mounting holes are provided on the sides of the gas box assembly and the mechanism room assembly. An insulating and fixing top plate for the mechanism room is installed on the upper part of the mechanism room assembly. An insulating and fixing left side plate and an insulating and fixing right side plate for the mechanism room assembly are provided on the side of the mechanism room assembly. An insulating and fixing bottom plate for the mechanism room is provided on the lower part of the mechanism room assembly.

[0006] In a preferred embodiment, the air box assembly, control room assembly, mechanism room assembly, and cable room assembly are welded from 304 stainless steel plates, which can prevent surface deformation of the air box assembly, control room assembly, mechanism room assembly, and cable room assembly.

[0007] In a preferred embodiment, the side of the gas box assembly is welded to the connecting bolts, which can fix the connecting bolts to the upper side of the gas box assembly.

[0008] In a preferred embodiment, the diameter of the connecting bolt is the same as the diameter of the positioning mounting hole, which facilitates the installation of the connecting bolt inside the positioning mounting hole.

[0009] In a preferred embodiment, the left and right insulating plates of the mechanism chamber are fixedly connected to the air box assembly by nuts, and the air box assembly and the mechanism chamber assembly can be connected by the nuts and connecting bolts.

[0010] In a preferred embodiment, the left side plate and the bottom plate of the mechanism chamber insulation fixing are Z-shaped bent, which facilitates the contact between the mechanism chamber assembly and the side plate of the air box assembly, while ensuring consistent appearance dimensions.

[0011] The beneficial effects of this utility model after adopting the above technical solution are as follows: the gas box assembly, control room assembly and cable room assembly can be fixed to each other by welding. Since the left side plate and bottom plate of the mechanism room insulation fixation adopt Z-shaped bending, the weld seam of the gas box assembly does not contact the sheet metal during assembly. At the same time, the connecting bolts are welded to the upper side of the gas box assembly and fixed with nuts. It only needs to be fixed to the side of the gas box. This is not affected by the gas box weld seam. The front of the gas box does not need to be welded with bolts, and there will be no thermal deformation. The assembly tolerance is no longer affected by the weld seam size. It can ensure the consistency of the appearance size of the assembled ring main unit and facilitate its on-site installation.

One side of the gas box assembly 1 is connected to the mechanism room assembly 3 via connecting bolts 9, allowing the gas box assembly 1 and the mechanism room assembly 3 to be connected. The control room assembly 2 is installed on the upper part of the mechanism room assembly 3, allowing the control room assembly 2 to be mounted on top of the mechanism room assembly 3. The cable room assembly 4 is installed at the lower part of the gas box assembly 1 and the mechanism room assembly 3, facilitating the connection between the cable room assembly 4 and the gas box assembly 1. The sides of the gas box assembly 1 and the mechanism room assembly 3 are provided with… The positioning mounting hole 8 allows the connecting bolt 9 to be placed inside. The upper part of the mechanism chamber assembly 3 is equipped with a mechanism chamber insulation fixing top plate 5, which improves the stability of the control chamber assembly 2. The side of the mechanism chamber assembly 3 is provided with a mechanism chamber insulation fixing left side plate 6 and a mechanism chamber insulation fixing right side plate 10, which ensures that both sides of the mechanism chamber insulation fixing left side plate 6 and mechanism chamber insulation fixing right side plate 10 are flat and the overlapping surface is flat, and will not be affected by the gas box weld. The lower part of the mechanism chamber assembly 3 is provided with a mechanism chamber insulation fixing bottom plate 7, which ensures the overall stability of the mechanism chamber assembly 3.

[0019] Furthermore, the air box assembly 1, control room assembly 2, mechanism room assembly 3, and cable room assembly 4 are welded from 304 stainless steel plates, which can prevent the surface of the air box assembly 1, control room assembly 2, mechanism room assembly 3, and cable room assembly 4 from deforming.

[0023] Furthermore, the left side plate 6 and the bottom plate 7 of the mechanism chamber insulation fixing are Z-shaped bends, which facilitates the contact between the mechanism chamber assembly 3 and the side plate of the air box assembly 1, while ensuring consistent appearance dimensions.

[0024] The principle of this invention is that welding allows for the mutual fixation of the gas box assembly 1, control room assembly 2, and cable room assembly 4. Furthermore, the use of 304 stainless steel plates for all housings prevents surface deformation of these components. The insulating left side plate 6 and the insulating bottom plate 7 of the mechanism room employ Z-shaped bends. During assembly, the welded seams of the gas box do not contact the sheet metal, eliminating the influence of weld dimensions on assembly tolerances and facilitating the assembly of the mechanism room assembly. 3. It contacts the side plate of the gas box assembly 1, and at the same time ensures that the appearance dimensions are consistent. It ensures that both sides of the left side plate 6 and the right side plate 10 of the mechanism chamber insulation fixing are flat and the overlapping surface is flat. It will not be affected by the gas box weld. The connecting bolt 9 can be fixed on the upper side of the gas box assembly 1. The gas box assembly 1 and the mechanism chamber assembly 3 can be connected by the nut and the connecting bolt 9. It can control the weld on the upper side of the gas box assembly 1 to be on the front, ensuring the consistency of its appearance dimensions and facilitating on-site cabinet installation.
