Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to a intensive bus duct. Background Art

[0002] When the inside of the bus duct is damp or in a humid environment for a long time, a small amount of water will accumulate or condensation will occur inside the bus duct. In most cases, the accumulated water or condensed dew may cause discharge, eventually causing the unit to trip and affecting normal power transportation.

[0003] Generally, water vapor or condensation enters the bus duct shell from the gap between the two ends of the conductive copper bar and the bus duct shell. Therefore, it is an urgent problem to seal the two ends of the conductive copper bar of the bus duct to prevent water or water vapor from entering the bus duct shell.

[0004] A dense bus duct with waterproof function disclosed in Chinese patent CN220527628U can seal the bus duct shell through the arranged sealing component, and at the same time, can seal the conductive copper busbar passing through the sealing component, that is, it blocks water vapor from entering the bearing cavity formed by the bus duct shell, and can avoid the influence of water vapor or condensation in the bearing cavity. The internal insulation effect is relatively high, and the position of the cover plate on the vertical section of the bus duct shell can be reinforced by the arranged fasteners, so that the overall stability of the bus duct is relatively high. However, all the conductive copper buses of the dense bus duct are tightly fitted together. In order to connect two bus ducts together, the ends of the conductive copper buses will be bent, so the dense bus duct is narrow in the middle and wide at the ends. Therefore, the dense bus duct with waterproof function has the following defects while solving the problem:

[0005] After the rubber sleeve inside the slot is put on the end of the bus duct, the rubber sleeve cannot seal the gap between the conductive copper bar and the bus duct shell, so it cannot play a sealing role. Utility Model Content

[0006] The purpose of the utility model is to solve at least one of the technical defects described in the background technology.

[0007] To this end, one purpose of the utility model is to propose a dense bus duct, aiming to solve the problem that the dense bus duct rubber sleeve with waterproof function in the prior art cannot seal the gap between the conductive copper bus and the bus duct shell, and thus cannot play a sealing role.

[0008] In order to achieve the above-mentioned purpose, an embodiment of one aspect of the utility model provides a dense bus duct, including a shell, wherein a plurality of conductive copper bars are arranged inside the shell, and an insulating sleeve is fixedly connected to the outer surface of the conductive copper bar, and positioning blocks are fixedly installed on both sides of the shell, and a first sealing plate and a second sealing plate are fixedly installed on one side of the two positioning blocks on both sides of the shell, respectively, a first sealing gasket is fixedly connected to a side of the first sealing plate close to the second sealing plate, and a second sealing gasket is fixedly connected to a side of the second sealing plate close to the first sealing plate.

[0009] Preferably, any of the above schemes is that a first hole groove is provided on one side of the first sealing plate, a second hole groove is provided on one side of the second sealing plate, and a second threaded hole is provided on one side of the positioning block. Bolts are used to penetrate the first hole groove and threadedly connected to the second threaded hole to achieve the purpose of fixing the first sealing plate, and bolts are used to penetrate the second hole groove and threadedly connected to the second threaded hole to achieve the purpose of fixing the second sealing plate.

[0010] Preferably, any of the above schemes is that a through hole is provided on one side of the first sealing plate, and a third threaded hole is provided on one side of the second sealing plate at a position corresponding to the through hole. Bolts are passed through the through hole and threadedly connected to the third threaded hole, so that the first sealing plate and the second sealing plate can clamp the conductive copper busbar, thereby allowing the first sealing gasket and the second sealing gasket to seal the conductive copper busbar.

[0011] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0012] 1. The first sealing plate and the second sealing plate are installed from both sides of the shell end, so they are not affected by the narrow middle part and wide end part of the intensive bus duct. After the first sealing plate and the second sealing plate are successfully installed at the end of the shell, the first sealing gasket and the second sealing gasket can seal the gap between the conductive copper busbar and the shell, thereby achieving a sealing effect and achieving the purpose of waterproofing and moisture-proofing.

[0013] 2. By setting a through hole on the first sealing plate and a third threaded hole on the second sealing plate, a bolt is used to penetrate the through hole and threadedly connect with the third threaded hole, and the bolt is tightened to make the first sealing plate and the second sealing plate close to each other until the first sealing plate and the second sealing plate clamp both sides of the conductive copper busbar. This design can avoid the problem of insufficient contact between the first sealing gasket and the second sealing gasket and the conductive copper busbar after the first sealing plate and the second sealing plate are installed on the side of the positioning block, thereby ensuring the sealing after installation.

[0025] Specifically, Figure 2 As shown, the shell 1 includes a left baffle 11, a right baffle 12, a bottom plate 13 and a cover plate 14. The cover plate 14 is located above the bottom plate 13, and the bottom plate 13 and the cover plate 14 have equal widths. The left baffle 11 and the right baffle 12 are fixedly connected to both sides of the bottom plate 13 and the cover plate 14, respectively. The conductive copper bus 2 is located in the gap between the left baffle 11, the right baffle 12, the bottom plate 13 and the cover plate 14.

[0026] Specifically, Figure 2 and Figure 4 As shown, mounting holes 15 are provided on the left baffle 11 and the right baffle 12, and a first threaded hole 31 is provided on one side of the positioning block 3. Bolts are used to penetrate the mounting holes 15 and are threadedly connected to the first threaded hole 31 on the positioning block 3, so that the positioning block 3 can be fixedly installed on the left baffle 11 and the right baffle 12.

[0027] Specifically, Figure 4 and Figure 5 As shown, a first hole groove 42 is provided on one side of the first sealing plate 4, a second hole groove 52 is provided on one side of the second sealing plate 5, and a second threaded hole 32 is provided on one side of the positioning block 3. A bolt is used to penetrate the first hole groove 42 and threadedly connected to a second threaded hole 32 on a positioning block 3, so that the first sealing plate 4 can be fixed to one side of the positioning block 3, and the bolt can slide in the first hole groove 52, and then a brush is used to penetrate the second hole groove 52 and threadedly connected to a second threaded hole 32 on a positioning block 3, so that the second sealing plate 5 can be fixed to one side of the positioning block 3, and the bolt can slide in the second hole groove 52.

[0028] Specifically, Figure 5 As shown, a through hole 43 is opened on one side of the first sealing plate 4, and a third threaded hole 53 is opened on one side of the second sealing plate 5 at a position corresponding to the through hole 43.

[0029] The working principle of the utility model is as follows: the left baffle plate 11 and the right baffle plate 12 are welded or riveted to the two sides of the bottom plate 13, and then a plurality of conductive copper bars 2 with insulating sleeves 21 on the surface are sequentially placed flat on the top of the bottom plate 13, the left baffle plate 11 and the right baffle plate 12 limit the conductive copper bars 2, and then the cover plate 14 is covered on the top of the conductive copper bars 2, and the mechanical lathe presses down the cover plate 14 through components such as cylinders, so that the bottom plate 13 and the cover plate 14 clamp the conductive copper bars 2, and then the cover plate 14 is welded or riveted together with the left baffle plate 11 and the right baffle plate 12, and at this time, the insulating sleeve 21 can seal the gap between the conductive copper bars 2 and the bottom plate 13 and the cover plate 14;

[0030] However, the side surfaces of the multiple conductive copper bars 2 are curved and not tight with the left baffle 11 and the right baffle 12, resulting in poor sealing. At this time, the positioning blocks 3 are fixedly installed on the left baffle 11 and the right baffle 12 by using bolts to penetrate the mounting holes 15 and threadedly connect with the first threaded holes 31 on the positioning blocks 3, and then the bolts are penetrated through the first hole grooves 42 and threadedly connected with the second threaded holes 32 on one positioning block 3 to fix the first sealing plate 4 on one positioning block 3. The side surface of the first sealing gasket 41 seals the gap between the first sealing plate 4 and the positioning block 3. Similarly, the second sealing plate 5 is fixed on the other positioning block 3. On the upper side, the side of the second sealing gasket 51 seals the gap between the second sealing plate 5 and the positioning block 3, and finally a bolt is used to penetrate the through hole 43 and threadedly connected with the third threaded hole 53 on the second sealing plate 5, and the bolt is tightened to make the first sealing plate 4 and the second sealing plate 5 close to each other. At this time, the bolts in the first hole groove 42 and the second hole groove 52 slide in the hole grooves respectively until the first sealing plate 4 and the second sealing plate 5 clamp the two sides of the conductive copper bus 2, so that the first sealing gasket 41 and the second sealing gasket 51 seal the side of the conductive copper bus 2, thereby preventing water vapor from entering the interior of the shell 1, thereby achieving the purpose of waterproofing and moisture-proofing.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. The first sealing plate 4 and the second sealing plate 5 are installed from both sides of the end of the shell 1, so they are not affected by the narrow middle part and wide end part of the intensive bus duct. After the first sealing plate 4 and the second sealing plate 5 are successfully installed at the end of the shell 1, the first sealing gasket 41 and the second sealing gasket 51 can seal the gap between the conductive copper bus 2 and the shell 1, thereby achieving a sealing effect and achieving the purpose of waterproofing and moisture-proofing.

[0033] 2. By setting a through hole 43 on the first sealing plate 4 and a third threaded hole 53 on the second sealing plate 5, a bolt is used to penetrate the through hole 43 and threadedly connect with the third threaded hole 53, and the bolt is tightened to make the first sealing plate 4 and the second sealing plate 5 close to each other until the first sealing plate 4 and the second sealing plate 5 clamp the two sides of the conductive copper bus 2. This design can avoid the problem of insufficient contact between the first sealing gasket 41 and the second sealing gasket 51 and the conductive copper bus 2 after the first sealing plate 4 and the second sealing plate 5 are installed on the side of the positioning block 3, thereby ensuring the sealing after installation.
