Description

Technical Field

[0001] The present invention relates to the technical field of bus ducts, and particularly to a sealing structure for the outer shell of a compact enclosed bus duct. Background Art

[0002] A bus duct with good sealing performance is used to distribute the power of each component in the power, including the outer shell of the bus duct and the copper bar, effectively ensuring the normal transmission of power; for the Chinese patent document with the publication number CN209104755U, it discloses a bus duct with good sealing performance, which points out that the sealing of the bus duct in the prior art is not tight enough, affecting the transmission efficiency, reducing the use quality of the bus duct, and easily leading to accidents; its solution is that there are rivets on the outer wall of the bus duct shell, and a circular sealing ring is arranged between the rivets and the bus duct shell. Through the circular sealing ring, the connection between the rivets and the bus duct shell can be isolated from the atmosphere, effectively preventing air leakage, thus ensuring the internal sealing of the bus duct, effectively eliminating accidental failures caused by external moisture and foreign objects, achieving the effect of good sealing performance, and improving the transmission efficiency; and there are overlapping buckles welded on the outer wall of the bus duct shell, and four overlapping buckles are provided, and the overlapping buckles are symmetrically distributed. Through the overlapping buckles, the connection between the bus duct shells can be made closer, preventing the appearance of gaps, improving the sealing performance of the bus duct, and thus effectively improving the sealing performance of the bus duct.

[0003] For the above-mentioned solution and the bus duct under the prior art, generally, a sealing strip is used for the sealing work at the side position of its outer shell, but the sealing protection of the end position of the bus duct is easily ignored. The copper bar and the end of the bus duct are inserted and connected, and it is easy to generate gaps at the connection position between the two, resulting in the inability to guarantee the connection sealing performance between the copper bar and the bus duct, and not meeting the actual use requirements, so improvement and optimization are needed.

[0028] The closed busbar housing sealing structure designed by the present invention mainly uses the housing end sealing assembly 3 provided to assist in sealing the connection position between the end of the busbar and the copper bar, improving the sealing performance of the busbar housing; that is, when performing the sealing assistance work on the connection position between the copper bar and the housing end, the middle gap insert 307 is adaptively inserted into the gap in the copper bar. The side of the copper bar is closely attached by the side insert 308. Then, the first fixed angle plate 301 is fixed by screws. Finally, the first locking threaded post 305 is tightened by the first knob 306. The first locking threaded post 305 passes through the first threaded hole 304 and enters the middle gap insert 307, and squeezes the slope 311 on the convex block 310, thereby pushing and pressing the sealing auxiliary plate 309 to closely adhere to the side wall of the copper sheet, squeezing and sealing the connection gap position between the copper bar and the housing end to ensure the stability of the sealing work; for the side insert 308, the first locking threaded post 305 enters it, and then one of the sealing auxiliary plates 309 is pushed and pressed.

The mounting screw 406 passes through the adjustment groove 405 and is threadedly fixed to the middle gap insertion block 307. The second locking threaded column 407 is threadedly connected to the second threaded hole 404 in a matching manner, and a second knob 408 is fixedly arranged at one end of the second locking threaded column 407; the adjustment groove 405 and the second threaded hole 404 are arranged at corresponding positions, and two groups of adjustment grooves 405 are symmetrically arranged; the middle gap insertion block 307 and the side insertion block 308 are detachable on the second fixing plate 403, and the distance between the middle gap insertion blocks 307 and the distance between the side insertion block 308 and the adjacent middle gap insertion block 307 can be adjusted.

[0031] In order to improve its working flexibility, the middle gap insert block 307 and the side insert block 308 are detachably arranged on the second fixing plate 403, that is, their spacing can be adjusted according to actual usage requirements, and the thickness of the middle gap insert block 307 and the side insert block 308 can be replaced and adjusted to meet actual usage requirements; first, the positions of the middle gap insert block 307 and the side insert block 308 are adjusted according to the gap of the copper bar, so that the distance between the middle gap insert blocks 307 and the distance between the side insert block 308 and the adjacent middle gap insert block 307 are adjusted. Then, the installation screw 406 passes through the adjustment slot 405 and is fixedly connected to the middle gap insert block 307. Finally, when installing the side insert block 308, it is also installed and fixed by the installation screw 406. Finally, the second locking threaded column 407 is tightened by the second knob 408, so that the second locking threaded column 407 presses the slope 311 on the convex block 310 in the middle gap insert block 307, and the connection gap position between the copper bar and the end of the housing is pressed and sealed; in this process, the installation and fixation of the middle gap insert block 307 and the side insert block 308 are mainly realized by the installation screw 406, which is convenient for their subsequent disassembly. Moreover, through the provided adjustment slot 405, which is set as a strip shape, its position can be arbitrarily adjusted, that is, the spacing adjustment flexibility is high, meeting actual usage requirements.
