Problems solved by technology

This structure not only has many connection points on the shell, but also requires a lot of assembly work, and the connection part of the shell is easy to seep water during use, which affects the safe operation of the equipment. Therefore, it is usually necessary to seal the joint between the side plate and the top plate. glue, which further increases the workload of installation, and during the operation of the equipment, the sealant is also easy to age and fall off, and the waterproof effect cannot be guaranteed

Embodiment Construction

[0013] like image 3 , Figure 4 As shown, the housing of the serrated meshing surface of the intensive busway includes two upper and lower cover plates 21 and a fixed side plate 22 connected between the two cover plates and biased to one side. The two cover plates 21 are connected to the fixed side The plate 22 is made of an aluminum alloy profile with an overall structure, and a movable side plate 23 with a C-shaped cross section is arranged between the two cover plates to the other side. The cover plate is connected and fixed by bolts or rivets. The cross-sectional shape of the joint surface of the flange and the upper and lower cover plates is a sawtooth shape that engages with each other (such as Figure 5 shown). The top cover plate 21 is also provided with a drain hole 211 , and the lateral position of the drain hole is located outside the fixed side plate 22 . The edges of the two flaps 231 of the movable side plate are folded outwards to form two sealing grooves 2...

Abstract

The invention belongs to a transmission facility, which relates to a housing structure for a compact bus duct, in particular to a sawtooth mating surface housing for a compact bus duct. The sawtooth mating surface housing for the compact bus duct comprises an upper cover plate, a lower cover plate and a fixed side plate connected between the two cover plates and biased towards one side. The two cover plates and the fixed side plate are made of aluminum alloy sectional bars in monolithic construction. A flexible side plate with C-shaped cross section is arranged between the two cover plates, and is biased towards the other side. The folded edges at the upper end and the lower end of the flexible side plate are fixedly connected with the cover plates through bolts or rivets. The cross sections of the junction surfaces between the folded edges, the upper cover plate and the lower cover plate are in the shape of saw teeth meshed with each other. The housing structure has the advantages of simple structure, convenient installation and effective watertightness.

Description

technical field [0001] The invention belongs to power transmission equipment, and relates to a shell structure of a medium-intensive bus duct, in particular to a serrated meshing surface shell of a dense bus duct. Background technique [0002] In the existing power transmission busbar system, the shell structure of dense busway is usually as attached figure 1 And attached figure 2 As shown, it consists of upper and lower cover plates 11 and two C-shaped side plates 12 on both sides. The flanges on the side plates and the lower ends are respectively connected and fixed with the two cover plates by bolts or rivets. This structure not only has many connection points on the shell, but also requires a lot of assembly work, and the connection part of the shell is easy to seep water during use, which affects the safe operation of the equipment. Therefore, it is usually necessary to seal the joint between the side plate and the top plate. Glue, which further increases the workloa...
