Description

Technical Field

[0001] The present invention relates to the technical field of bus ducts, and more particularly to a heat dissipation type bus duct. Background Art

[0002] Bus duct is a closed metal device composed of copper and aluminum busbars, which is used to distribute high power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] A patent application with publication number CN113241698B discloses a bus duct, including a bus duct body, auxiliary heat sinks are embedded in the top and bottom of the bus duct body, heat dissipation holes are penetrated on the auxiliary heat sink, one end of the heat dissipation hole is located inside the bus duct body, and the other end is located outside the bus duct body, and heat-driven cavities are opened in the auxiliary heat sink on both sides of the heat dissipation hole. The bus duct body can be cooled by arranging auxiliary heat dissipation holes on the auxiliary heat sink to prevent the internal temperature of the bus duct body from being too high, which may lead to a reduction in the service life of the internal components of the bus duct body. The heat-driven cavity and the heat-driven ball can control the sealing mechanism to seal the heat dissipation holes through the transmission mechanism in the event of a fire. The fire outside the bus duct body will not damage the internal components of the bus duct, so that the building can continue to be powered even in the event of a fire.

[0004] Although the above-mentioned device can seal the bus duct body when a fire occurs during use, dust may clog the holes provided on the bus duct during use.

[0019] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0020] like Figures 1 to 3 As shown, a heat dissipation bus duct according to an embodiment of the present invention comprises a housing 1, a first metal connection block 11 and a second metal connection block 13 are arranged at both ends of the housing 1, a metal stopper 12 is arranged outside the first metal connection block 11 and the second metal connection block 13 on the housing 1, a middle partition 15 is arranged inside the housing 1, and an isolation device 2 is arranged on the housing 1; like Figures 4 to 6 As shown, the isolation device 2 includes a side isolation piece 21, and the outer wall of the shell 1 is provided with a plurality of heat dissipation isolation plates 221. When the heat dissipation isolation plates 221 are in contact with the outer wall of the shell 1, the shell 1 is cooled. The movement of the side isolation piece 21 drives the heat dissipation isolation plates 221 to rotate, so that the plurality of heat dissipation isolation plates 221 are in rotational contact to seal the outer wall of the shell 1. The side isolation piece 21 is in contact with the side of the heat dissipation isolation plate 221 to form a sealed cavity to seal the outside of the shell 1. A transmission device 3 is provided on the side of the side isolation piece 21, and the transmission device 3 includes a locking piece 37 and a U-shaped rod 31. The locking piece 37 is used to detect the external temperature and pull the U-shaped rod 31 to move toward the center of the shell 1.

[0021] It should be noted that, considering that the sealing holes of the bus duct in the prior art may be blocked during use, if the sealing holes are blocked, the heat dissipation effect will be poor. Therefore, although the bus duct can be used in the event of a fire, it cannot have a good heat dissipation effect in normal use. In order to solve this problem, the following improvements have been made: First, install the bus duct at the position to be used. In the initial state, the heat dissipation isolation plate 221 on the heat dissipation isolation piece 22 always maintains a vertical position with the outer wall of the shell 1, and the shell 1 is also provided with an elastic thermal conductive pad, so that the heat dissipation isolation plate 221 can be in full contact with the shell 1, thereby conducting heat, and multiple heat dissipation isolation plates 221 can improve the heat dissipation efficiency. When a fire occurs, it is necessary to seal the outside of the shell 1. A telescopic rod can be provided at the end of the shell 1, and then the U-shaped rod 31 is driven by the telescopic rod to shrink and move toward the center position of the shell 1. Then the U-shaped rod 31 drives the side isolation piece 21 to move toward the center position of the shell 1, and the side isolation piece 21 and the heat dissipation isolation piece 22 are in a threaded connection state. During the movement of the side isolation piece 21, the heat dissipation isolation plate 221 is driven to rotate until the side isolation piece 21 is fully engaged with the protrusion on the heat dissipation isolation piece 22, thereby achieving a sealing effect on both sides, and when the side isolation piece 21 is fully engaged with the heat dissipation isolation piece 22, the heat dissipation can be driven When the isolation plate 221 rotates 90°, the heat dissipation isolation plate 221 is parallel to the outer wall of the shell 1, so that multiple heat dissipation isolation plates 221 are connected end to end to achieve a sealing effect. The heat dissipation isolation plate 221 is in contact with the shell 1 when not rotated, so that the shell 1 is dissipated during normal use. When the heat dissipation isolation plate 221 is rotated 90°, the outside of the shell 1 can be sealed, so as to prevent the shell 1 from being damaged by heat generated both inside and outside the shell 1 in the event of a fire, and the heat dissipation isolation plate 221 will not be blocked by dust, thereby improving the heat dissipation effect. After use, the telescopic rod can be fully extended and the angle of the heat dissipation isolation plate 221 can be adjusted to dissipate heat for the shell 1 again. A middle partition 15 is provided on the shell 1, which can improve the heat dissipation effect during use. Compared with being gathered together by casting, it has a good heat dissipation effect. The three live wires, the neutral wire and the ground wire are separated to reduce the possibility of short circuit and improve safety.

[0022] like Figures 3 to 5 As shown, the first protrusions 14 are provided at both ends of the shell 1, and the side isolation member 21 includes a side sealing plate 211 slidably mounted on the outside of the first protrusion 14, and a plurality of sealing grooves 212 are provided inside the side sealing plate 211, and threaded holes 213 are opened inside the sealing grooves 212, and the sealing grooves 212 and the threaded holes 213 are used for engaging and sealing with the heat dissipation isolation member 22.

[0023] It should be noted that a sealing groove 212 and a threaded hole 213 are provided on the side sealing plate 211. The sealing groove 212 can engage with the heat dissipation isolation member 22 to seal the outer wall side of the shell 1. The threaded hole 213 engages with the heat dissipation isolation member 22, so that when the side sealing plate 211 moves, the heat dissipation isolation plate 221 can be driven to rotate and adjust the angle, thereby achieving the effect of adjusting the angle of the heat dissipation isolation plate 221 and sealing.

[0024] like Figure 5 and Figure 8 As shown, the heat dissipation isolation member 22 includes a plurality of limit blocks 222 fixedly mounted on the outer wall of the shell 1, a heat dissipation isolation plate 221 is rotatably mounted on the side wall of the limit block 222, a threaded rod 223 is rotatably mounted inside the limit block 222, the end of the threaded rod 223 is fixedly mounted on the side wall of the heat dissipation isolation plate 221, the outer wall of the threaded rod 223 is engaged with the inner wall of the threaded hole 213, and the limit block 222 is engaged with the sealing groove 212 to form a sealed space.

[0025] It should be noted that when the side isolation member 21 approaches the center position of the shell 1, the sealing groove 212 engages with the limit block 222 to achieve a sealing effect, and the threaded rod 223 engages with the threaded hole 213, and when the side sealing plate 211 moves, the threaded rod 223 is driven to rotate, and the rotation of the threaded rod 223 can drive the heat dissipation isolation plate 221 to rotate 90°, thereby adjusting the angle of the heat dissipation isolation plate 221.

[0026] like Figure 8 As shown, an isolation sealing block 23 is fixedly installed on the end side wall of the heat dissipation isolation plate 221, and a plurality of first grooves 231 are arranged on the top of the heat dissipation isolation plate 221. Second protrusions 232 are symmetrically arranged on the isolation sealing block 23 on the heat dissipation isolation plate 221, and a first rotating long plate 24 is rotatably installed inside the second protrusion 232. A right-angle rotating plate 241 is arranged on the side of the first rotating long plate 24, and the first rotating long plate 24 and the right-angle rotating plate 241 are vertically installed, and the right-angle rotating plate 241 is rotated to engage with the first groove 231.

[0027] It should be noted that, since the position where the bottom of the heat dissipation isolation plate 221 contacts the shell 1 is in an arc shape and needs to contact the elastic heat-conducting material provided on the shell 1, an isolation sealing block 23 and a first groove 231 are provided at the top of the heat dissipation isolation plate 221, and the second protrusion 232 is rotatably installed with the first rotating long plate 24, and a torsion spring is provided at the installation position of the second protrusion 232 and the first rotating long plate 24, so that the isolation sealing block 23 and the first rotating long plate 24 are in a vertical state under normal circumstances, and when the heat dissipation isolation plate 221 is rotated, the second protrusion 232 and the first rotating long plate 24 are rotated. When 221 rotates, the bottom of the heat dissipation isolation plate 221 contacts with the right-angle rotating plate 241 during the rotation process, thereby driving the right-angle rotating plate 241 to engage with a position close to the first groove 231 until the first groove 231 is fully engaged with the right-angle rotating plate 241. Then, the first rotating long plate 24 and the isolation sealing block 23 are in a parallel state. Then, the isolation sealing block 23 and the first rotating long plate 24 can protect the bottom of the heat dissipation isolation plate 221, so that the two heat dissipation isolation plates 221 have a better sealing effect when they are horizontal.

[0028] like Figure 6 As shown, the transmission device 3 includes a U-shaped rod 31 fixedly mounted on the side wall of the side sealing plate 211, a rotating pull block 32 is rotatably mounted on the outside of the U-shaped rod 31, and a second fixed block 33 is rotatably mounted on the end of the rotating pull block 32, a second rotating long plate 34 is fixedly mounted on the side of the second fixed block 33, a second rotating rod 341 is rotatably mounted on the inside of the second rotating long plate 34, and the second rotating rod 341 is fixedly mounted on the inside of the middle partition bin 15 for sealing the middle partition bin 15, a third fixed block 36 is provided at the lower part of the U-shaped rod 31, a first telescopic rod 35 is fixedly mounted on the side wall of the third fixed block 36, and the end of the first telescopic rod 35 is fixedly mounted on the end side wall of the shell 1, and the first telescopic rod 35 drives the U-shaped rod 31 to extend and retract through the third fixed block 36.

[0029] It should be noted that, since the side isolation piece 21 needs to be moved during use, a U-shaped rod 31 is provided on the side wall of the side sealing plate 211. When the side sealing plate 211 needs to be moved, the first telescopic rod 35 can be started to contract, thereby driving the U-shaped rod 31 to move toward the center position close to the shell 1, and the outer wall of the U-shaped rod 31 is provided with a rotating pull block 32, and the end of the rotating pull block 32 is connected to the second fixed block 33, thereby driving the second rotating long plate 34 to rotate, and the second rotating long plate 34 is installed inside the middle partition chamber 15, so it can drive the second rotating long plate 34 to rotate 90°, thereby sealing the two ends of the middle partition chamber 15 to prevent the interior of the shell 1 from being affected when a fire occurs, thereby improving the safety of the shell 1 when used in a fire.

[0030] like Figures 2 to 3As shown, a plurality of second heat dissipation plates 25 are fixedly installed inside the middle partition chamber 15, and the second heat dissipation plates 25 are used to dissipate the heat generated by the first metal connecting block 11 and the second metal connecting block 13, and the second rotating long plate 34 is used to seal the middle partition chamber 15 and the second heat dissipation plates 25 inside the middle partition chamber 15.

[0031] It should be noted that, since the interior of the middle partition chamber 15 will also dissipate heat during normal use, in order to improve the heat dissipation effect, a second heat dissipation plate 25 is provided inside the middle partition chamber 15. When the shell 1 is in normal use, wind blowing through the interior of the middle partition chamber 15 can bring a large amount of heat, thereby improving the heat dissipation effect. Second rotating long plates 34 are provided at both ends of the middle partition chamber 15. In the event of a fire, the interior of the middle partition chamber 15 can be sealed, and the length of the second heat dissipation plate 25 is less than the distance between the two second rotating long plates 34.

[0032] like Figure 6 As shown, a locking member 37 is installed at a symmetrical position of the third fixed block 36 on the outer wall of the U-shaped rod 31, and the locking member 37 includes a fourth fixed block 371 fixedly installed on the outer wall of the U-shaped rod 31, a first cylinder 372 is slidably installed inside the fourth fixed block 371, a first spring 373 is fixedly installed on the side wall of the first cylinder 372, an end of the first spring 373 is fixedly installed on the side wall of the fourth fixed block 371, an end of the first cylinder 372 is fixedly installed on the side wall of the shell 1, a third fixed plate 378 is fixedly installed on the outer wall of the first cylinder 372, a third limiting plate 374 is fixedly installed on the side wall of the third fixed plate 378, locking strips 375 are rotatably installed at both ends of the third limiting plate 374, support columns 376 are fixedly installed at both ends of the third fixed plate 378, a thermal transmission member 377 is fixedly installed inside the support column 376, and an end of the thermal transmission member 377 is fixedly contacted with the end of the locking strip 375.

[0033] It should be noted that, considering that the exterior of the shell 1 can be automatically insulated and sealed in the event of a fire, a thermal transmission member 377 is provided inside the support column 376. The thermal transmission member 377 can sense heat and expand to lift the locking strip 375, thereby driving the two locking strips 375 to rotate inside the third limit plate 374, thereby increasing the distance between the ends of the two locking strips 375. The fourth fixing block 371 is driven by the first spring 373 to move the U-shaped rod 31 toward the center position of the shell 1. The end of the locking strip 375 is a right angle on the outside and a rounded angle on the inside. Therefore, in a normal state, the fourth fixing block 371 can be lifted. When the fourth fixing block 371 needs to be restored to its original position, it can be reset by starting the first telescopic rod 35. This device can respond quickly when a fire occurs. Compared with using a telescopic rod, it may get stuck in the middle position and will not cause the shell 1 to be unable to be completely sealed.

[0034] like Figure 6 As shown, a torsion spring is arranged inside the installation position of the third limiting plate 374 and the locking strip 375 so that the two locking strips 375 are close to each other in a normal state, and the minimum distance between the ends of the locking strips 375 is smaller than the outer diameter of the fourth fixing block 371.

[0035] It should be noted that a torsion spring is arranged inside the installation position of the third limiting plate 374 and the locking strip 375 so that the two locking strips 375 are close to each other in a normal state, and the minimum distance between the ends of the locking strip 375 is smaller than the outer diameter of the fourth fixed block 371, so that the locking strip 375 can lift the fourth fixed block 371 during normal use.

[0036] like Figure 8 As shown, a torsion spring is provided at the installation position of the second protrusion 232 and the first rotating long plate 24 so that the isolation sealing block 23 and the first rotating long plate 24 are in a vertical state.

[0037] It should be noted that a torsion spring is provided at the installation position of the second protrusion 232 and the first rotating long plate 24 so that the isolation sealing block 23 and the first rotating long plate 24 are in a vertical state.

[0038] like Figure 7 As shown, the installation positions of the second rotating rod 341 and the U-shaped rod 31 are staggered, so that there will be no dead angle when the rotating pull block 32 lifts up the second rotating long plate 34 .

[0039] It should be noted that the installation positions of the second rotating rod 341 and the U-shaped rod 31 are staggered, so that there is no dead angle when the rotating pull block 32 lifts up the second rotating long plate 34 .

[0040] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
