Description

Technical Field

[0001] The present invention belongs to the technical field of bus ducts, and in particular relates to a bus duct structure with high-efficiency heat dissipation. Background Art

[0002] Busbar ducting is an efficient and flexible power transmission system consisting of copper or aluminum conductors encased in a metal casing. It utilizes a modular design to achieve centralized power distribution. Its origins stem from the demand for high-current, high-density power supply in the industrial and construction sectors. Compared to traditional cables, busbar ducting offers advantages such as high current carrying capacity, easy installation, and strong scalability. It has gradually become a core solution for modern power distribution. At the same time, busbar ducting must strictly adhere to standard operating procedures. Before installation, the busbar duct must be selected based on load current (e.g., 400A to 6300A), voltage level (400V / 690V), and environmental conditions (e.g., humidity and fire protection requirements). Common types include air-insulated, dense, and fire-resistant. During installation, the main body of the bus duct is fixed by a bracket. For segmented connections, the joints need to be cleaned and coated with conductive paste to ensure that the bolts are tightened to the specified torque. The casing is grounded throughout (resistance ≤ 4Ω). Insulation testing (resistance ≥ 20MΩ) and temperature rise monitoring are required before power is applied. Daily maintenance requires regular inspection of the tightness of the joints, cleaning of dust accumulation, and use of infrared equipment to monitor temperature anomalies. At the same time, bus ducts directly supply power to heavy equipment in industrial plants, reducing cable laying costs; they replace dense cables in the shafts of high-rise buildings, saving space and improving safety; data centers flexibly distribute cabinet power through plug-in boxes and support modular expansion; commercial complexes use their branching convenience to achieve hierarchical power distribution. In addition, bus ducts can also adapt to special environments, such as IP65 high protection grade for outdoor use, and fire-resistant types that meet fire protection requirements. With its high efficiency, reliability, and flexibility, bus ducts have become an indispensable component of modern power systems, especially in areas with stringent requirements for power supply continuity, space utilization, and scalability.

[0003] At the same time, after searching existing public documents, patent document CN109412099B discloses a bus duct with high efficiency in heat dissipation, belonging to the field of power transmission trunk lines. The key points of its technical solution are as follows: it includes a bus duct body, a cover plate, an inner cavity, and a dovetail groove. The side walls of the bus duct body are fixedly mounted with the cover plate, the inner cavity is fixedly mounted inside the bus duct body, and the inner cavity is tightly fitted with the inner wall of the cover plate. The outer wall of the bus duct body is tightly fitted with an aluminum alloy protective shell, and the left and right ends of the aluminum alloy protective shell are connected to the cover plate. The upper wall of the bus duct body is connected with a through hole, which is connected to the top of the aluminum alloy protective shell. The inner wall of the bus duct body is fixedly mounted with a double-connected copper busbar. This bus duct with high efficiency in heat dissipation uses the aluminum alloy protective shell to dissipate heat through air conduction. The side panels are equipped with heat sinks, the outer walls are equipped with raised ribs, and the side panels are designed as a dovetail groove structure, which effectively helps the bus duct dissipate heat, thereby reducing stability and reducing safety risks.

[0004] The patent document with patent number CN221009762U discloses an integrated bus duct structure with high efficiency in heat dissipation, including an outer shell, a conductive row is arranged in the outer shell through an insulating support, a heat dissipation shell is arranged on both sides of the outer shell, the outer shell and the heat dissipation shell are connected to form a heat dissipation space, a heat conduction plate assembly is arranged in the heat dissipation space, and a heat dissipation fan is arranged at both ends of the heat dissipation shell; an air intake assembly is arranged on the outer shell, the air intake assembly is used to transport natural air to the outer shell and cool and dissipate heat inside the outer shell, the utility model is provided with a heat dissipation shell, a heat conduction longitudinal plate, a heat conduction horizontal plate, a heat dissipation fan, an air intake shell and an air intake hole, external natural air enters the air intake shell through the air intake hole, naturally cools the conductive row in the heat dissipation shell and reduces the temperature inside the heat dissipation shell, and the hot air in the outer shell is discharged through the heat dissipation fan, so that the air circulates in the heat dissipation shell, accelerates the heat dissipation speed of the bus duct, and improves the heat dissipation efficiency of the bus duct.

[0005] However, during the installation process of the existing bus duct structure, although multiple structures are assembled, most of the multiple structures are installed and fixed by bolts, the bus duct structure cannot be quickly disassembled and assembled using the bolt installation method. Each time it is disassembled, multiple bolts are rotated one by one to disassemble it. However, this disassembly and assembly method is too cumbersome, which reduces the ease of operation and affects the efficiency of structural inspection or maintenance of the bus duct. At the same time, when using the bus duct structure, since multiple groups of connecting plate structures for power supply are used therein, the multiple groups of connected plate structures for power supply are prone to shaking during the installation process or subsequent use of the bus duct, resulting in misalignment between the multiple groups of connected plate structures, and the stability of the power supply process cannot be guaranteed. Summary of the Invention

[0006] The purpose of the present invention is to provide a bus duct structure with efficient heat dissipation. By rotating the linkage plate in the circular mouth, the operating efficiency is improved, and the disassembly and assembly work can be completed by a single person, thereby improving the operating efficiency, thereby facilitating the disassembly and assembly of the assembly plate. At the same time, the locking screw locks and positions the two sets of positioning plates at the upper and lower parts of the connecting piece, thereby achieving the stability of the position of the connecting piece and ensuring the stable power supply of the bus duct in the working state.

[0011] Furthermore, mounting holes are provided on the side walls of the positioning plates at positions corresponding to the locking screws, and the ends of the locking screws that are spirally passed through the mounting holes are spirally connected with external gear ring nuts, and the external gear ring nuts are abutted against the side faces of the positioning plates, and the opposite end faces of the two groups of positioning plates in the same upward and downward directions are provided with two circular toothed plates that are respectively meshed with the external gear ring nuts.

[0012] Furthermore, rotating holes are provided at positions corresponding to the circular tooth plates on the side surfaces of the positioning plate connected to the circular tooth plates, and two movable openings are provided on the side surfaces of the positioning plate connected to the insulating sleeve, which are respectively connected to the inside of the rotating holes, and the circular diameter of the movable openings is larger than the inner diameter of the rotating holes. The inner wall of the movable opening is fixed with a plurality of convex strips evenly distributed along the circumferential wall and flush with the side surfaces of the positioning plate, and the length of the convex strips is consistent with half the depth of the movable opening.

[0013] Furthermore, a rotating rod passing through the inner position of the rotating hole is fixed to the end surface of the scalloped plate, and a movable plate flush with the side surface of the positioning plate is fixed to the end surface of the rotating rod at the inner end of the movable opening.

[0014] Furthermore, a second spring is fixed to the end face of the movable plate opposite to the power connection plate. The second spring is mounted on the corresponding rotating rod, and the other end face of the second spring is in contact with the inner end face of the movable opening. Recesses are provided on the surface side walls of the movable plate at the positions corresponding to the convex strips, and multiple convex strips are respectively located inside the corresponding recesses.

[0015] Furthermore, blocking plates are provided on both end faces of the wire frame on the left and right sides of the square opening, and the end faces of the multiple electrical connection plates passing through the square opening are located between the two blocking plates at each end of the wire frame, and the blocking plates are connected to the end faces of the wire frame by bolts.

[0016] Furthermore, blocking holes are provided on the front and rear parts of the left and right sides of the assembly plate, movable holes are provided on the inner end faces of the blocking holes, plugging holes are provided on the inner walls of the assembly openings at positions corresponding to the blocking holes, and assembly rods are provided inside the blocking holes for plugging into the inner positions of the plugging holes.

[0019] 1. When the linkage plate is controlled to rotate inside the round mouth, the linkage plate will drive multiple pull ropes to move synchronously in the curved hole, and the pull ropes will be retracted at one time. As a result, the pull ropes will pull the movable plate, causing the movable plate to drive the corresponding assembly rod to move out of the inside of the plug-in hole. In this way, one person can control the extension and retraction of the assembly rod with one hand, thereby improving the efficiency of assembly and disassembly of the linkage plate.

[0020] 2. The spring pushes the circular tooth plate so that the circular tooth plate and the positioning plate are always in a connected state. Therefore, after the outer ring nut rotates on the locking screw and connects with the positioning plate, the circular tooth plate and the outer ring nut are in a meshing state, so that the outer ring nut cannot rotate automatically on the locking screw, so that the distance between the two outer ring nuts with the same upper and lower positions cannot be easily adjusted, and the distance between the upper and lower two sets of positioning plates cannot be easily adjusted. Therefore, after the two sets of positioning plates clamp the multiple sets of terminal blocks, they are combined between the outer ring nuts and the circular tooth plates to ensure that the multiple sets of terminal blocks cannot be deviated or misplaced, thereby achieving a stable position of the terminal blocks and ensuring stable power supply of the bus duct in the working state.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The present invention is a bus duct structure with efficient heat dissipation. The linkage plate 202 rotates in the circular mouth 2011 to improve the operating efficiency, so that a single person can complete the disassembly and assembly work, thereby improving the operating efficiency, thereby facilitating the disassembly and assembly of the assembly plate 201. At the same time, the locking screw 502 locks and positions the two sets of positioning plates 501 at the upper and lower parts of the connecting plate 401, thereby achieving the stability of the position of the connecting plate 401 and ensuring the stable power supply of the bus duct in the working state.

[0041] Specifically, the frame assembly 1 includes a wire frame 101, and the upper and lower end surfaces of the wire frame 101 are provided with assembly openings 1012 connected to the interior thereof; the linkage assembly assembly 2 includes two sets of assembly plates 201 located inside the assembly openings 1012, and the middle portions of the end surfaces of the two sets of assembly plates 201 away from the wire frame 101 are provided with circular openings 2011, and the interiors of the circular openings 2011 are provided with linkage plates 202; the heat dissipation assembly 3 includes two sets of assembly plates located on the left and right sides of the wire frame 101. The assembly frame 301 and the heat sink 302 fixed to the assembly frame 301, the wiring assembly 4, including multiple power connection plates 401 evenly distributed on the left and right sides inside the wire frame 101, two sets of locking and positioning assemblies 5 arranged in the front and back positions inside the wire frame 101, each set of locking and positioning assemblies 5 including two sets of positioning plates 501 respectively located above and below the power connection plates 401, and locking screws 502 are provided between the two sets of positioning plates 501 located on the left and right sides of the power connection plates 401;

[0042] By setting up and using the above-mentioned structure, when using the bus duct, first confirm that the bus duct is not deformed, and confirm that the insulating sleeve 401 is intact, and clean the corresponding terminal piece 401 joint part, and apply conductive paste to its position, plug the connector in the equipment into the corresponding terminal piece 401 one by one, and then use bolts to fasten the terminal piece 401 and the joint position of the equipment. At the same time, before using the bus duct, two sets of locking and positioning components 5 are set at the front and back parts inside the wire frame 101, so that the positioning plates 501 on each set of locking and positioning components 5 are respectively connected to the upper and lower parts of multiple terminal pieces 401, and the two sets of positioning plates 501 at the upper and lower parts are connected by locking screws 502, so that the two sets of positioning plates 501 clamp the multiple terminal pieces 401, thereby ensuring that the positions of multiple terminal pieces 401 cannot be staggered up and down, ensuring multiple The position of each power connection piece 401 is stable. At the same time, when the structure inside the wire frame 101 needs to be repaired or replaced, the linkage plate 202 can be controlled to rotate inside the circular opening 2011 to disengage the assembly connection between the assembly plate 201 and the wire frame 101, and then the assembly plate 201 can be taken out from the inside of the assembly opening 1012. At this time, the interior of the wire frame 101 can be exposed, and the positioning plate 501 and the locking screw 502 therein can be disassembled and processed, so as to facilitate its replacement or repair. At the same time, whether the power connection piece 401 inside the wire frame 101 is intact can be checked. When the bus duct is connected to external equipment and energized, the heat generated inside it is conducted to the external environment through the heat sink 302, thereby reducing the temperature inside the bus duct. The assembly frame 301 is installed on both sides of the bus duct, thereby improving the efficient heat dissipation of the heat inside the wire frame 101.

[0043] Further, according to Figure 2 、 Figure 3 and Figure 9 , both sides of the wire frame 101 are provided with mounting openings 1014 connected to the interior thereof, and the two sets of assembly frames 301 are respectively inserted into the corresponding mounting openings 1014, and the assembly frames 301 and the wire frame 101 are assembled by means of provided bolts. The assembly frames 301 are fixed in the mounting openings 1014 by the bolts, thereby ensuring that the heat sink 302 fixed on the side wall of the assembly frame 301 conducts heat to the inside of the wire frame 101. At the same time, by controlling the screwing of the bolts, the disassembly and assembly of the assembly frame 301 is facilitated, so that the assembly frame 301 can be replaced.

[0044] Further, according to Figure 2 and Figure 9, blocking plates 102 are provided on both end surfaces of the wire frame 101 located on the left and right sides of the square opening 1011, and the end surfaces of multiple power connection plates 401 passing through the square opening 1011 are located between the two blocking plates 102 at each end of the wire frame 101. The blocking plates 102 are connected to the end surfaces of the wire frame 101 by bolts, and the blocking plates 102 are installed at the two end positions of the wire frame 101 by bolts, so that the multiple power connection plates 401 are located between the two blocking plates 102, and the multiple power connection plates 401 are protected by the blocking plates 102, and the external connectors can be bolted to the blocking plates 102, so that the connectors on the external devices are shielded from the power connection plates 401, thereby improving the connection sealing between the external devices and the bus duct and improving the connection safety.

[0045] It should be noted that the locking screw 502 , the positioning plate 501 and the power connection plate 401 are blocked by the insulating sleeve 401 to prevent the locking screw 502 and the positioning plate 501 from conducting electricity, thereby ensuring the safety of the power supply inside the wire frame 101 .

[0046] Example 2: Please refer to Figure 4 and Figure 9 On the basis of the specific embodiment 1, the insulating sleeve 4011 is directly sleeved on the power strip 401 to improve the safety of the bus duct and avoid short circuits due to contact between multiple power strips 401.

[0047] Specifically, both ends of the wire frame 101 are provided with square openings 1011 connected to the interior thereof. A limit block 402 is inserted into the interior of each square opening 1011. An insulating sleeve 4011 is sleeved on the front side of each power connection piece 401. Both ends of the power connection piece 401 and the insulating sleeve 4011 pass through the openings provided on the side walls of the limit blocks 402, and the front side of the insulating sleeve 4011 abuts against the inner sidewalls of the openings.

[0048] By setting and using the above structure, the insulating sleeve 4011 is sleeved on the power connection plate 401 to block the multiple power connection plates 401 and prevent the multiple power connection plates 401 from contacting each other. At the same time, the insulating sleeve 4011 and the power connection plates 401 pass through the opening on the side wall of the limit block 402. Therefore, the limit block 402 limits the multiple groups of insulating sleeves 4011 and the power connection plates 401. At the same time, the limit block 402 is located in the square opening 1011, thereby allowing the limit block 402 to be installed in the square opening 1011.

[0049] Example 3: Please refer to Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 10On the basis of the specific embodiment 1, the outer ring nut 5021 is engaged with the circular tooth plate 503 to ensure that the upper and lower sets of positioning plates 501 stably clamp the power connection plate 401 and ensure that the power connection plate 401 will not deviate at will.

[0050] Specifically, the side walls of the positioning plate 501 are provided with mounting holes 5012 at the positions corresponding to the locking screws 502. The ends of the locking screws 502 that are screwed through the mounting holes 5012 are both screwedly connected to the ends of the outer gear ring nuts 5021, and the outer gear ring nuts 5021 are in contact with the side surfaces of the positioning plate 501. The opposite end faces of the two groups of positioning plates 501 that are in the same vertical direction are provided with two circular toothed plates 503 that are respectively engaged with the outer gear ring nuts 5021. The side of the positioning plate 501 connected to the circular toothed plates 503 is Rotating holes 5011 are provided at positions corresponding to the scalloped plates 503. The side of the positioning plate 501 connected to the insulating sleeve 4011 is provided with two movable openings 5013, each of which is connected to the interior of the rotating holes 5011. The diameter of the movable openings 5013 is larger than the inner diameter of the rotating holes 5011. A rotating rod 5032 is fixed to the end surface of the scalloped plate 503, which passes through the interior of the rotating holes 5011. The end surface of the rotating rod 5032 at the inner end of the movable openings 5013 is fixed with a movable plate 5031 that is flush with the side surface of the positioning plate 501.

[0051] By setting and using the above structure, the outer gear ring nut 5021 is engaged with the corresponding circular tooth plate 503, so the circular tooth plate 503 limits the outer gear ring nut 5021. Therefore, when the position of the circular tooth plate 503 does not rotate or move, the outer gear ring nut 5021 cannot rotate on the locking screw 502. When the outer gear ring nut 5021 is screwed on the positioning plate 501, it is ensured that the positioning plate 501 is tightly attached to the power strip 401, thereby When the outer gear ring nut 5021 is unable to move, the positioning plate 501 will clamp the multiple connecting pieces 401, so that the multiple connecting pieces 401 cannot be staggered and deflected, thereby ensuring the stability of the position of the connecting pieces 401. At the same time, when it is necessary to screw down the outer gear ring nut 5021 on the end of the locking screw 502 and remove the positioning plate 501, the circular toothed plate 503 can be controlled to move in the direction away from the positioning plate 501, so that the circular toothed plate 503 drives the rotating rod 5032 to move inside the rotating hole 5011, and drives the movable plate 5031 to move inside the movable opening 5013, and the circular toothed plate 503 can be controlled to stagger with the outer gear ring nut 5021. At this time, the outer gear ring nut 5021 rotates along the end direction of the locking screw 502. When the outer gear ring nut 5021 is rotated to a certain distance, so that the distance between the outer gear ring nut 5021 and the positioning plate 501 is greater than the thickness of the circular toothed plate 503, the circular toothed plate 503 is 503 is loosened, so that the circular tooth plate 503 is reconnected with the positioning plate 501, ensuring that the circular tooth plate 503 does not limit the outer ring nut 5021, so that the outer ring nut 5021 can be directly screwed out at the end position of the locking screw 502, so that the upper and lower sets of positioning plates 501 no longer clamp the power connection plate 401, so that the positioning plate 501 can be taken out of the wire frame 101, and the positioning plate 501 and the locking screw 502 can be disassembled and replaced.

[0052] Example 4: Please refer to Figure 8 and Figure 10 On the basis of the specific embodiment 3, the convex strip 5014 is located in the notch 5034 to limit the movable plate 5031 and prevent the scalloped plate 503 from rotating randomly. At the same time.

[0053] Specifically, a second spring 5033 is fixed to the end surface of the movable plate 5031 opposite to the power connection plate 401. The second spring 5033 is sleeved on the corresponding rotating rod 5032, and the other end surface of the second spring 5033 abuts the inner end surface of the movable opening 5013. The surface side wall of the movable plate 5031 is provided with a recess 5034 at the position corresponding to the ridge 5014. The plurality of ridges 5014 are respectively located within the corresponding recess 5034. The inner wall of the movable opening 5013 is fixed with a plurality of ridges 5014 evenly distributed along the circumferential wall and flush with the side surface of the positioning plate 501. The length of the ridge 5014 is consistent with half the depth of the movable opening 5013.

[0054] By setting and using the above structure, the convex strip 5014 is in the recess 5034, so when the movable plate 5031 is in the movable opening 5013 within the range of the convex strip 5014, the movable plate 5031 will be limited by the convex strip 5014, resulting in the movable plate 5031 being unable to rotate in the movable opening 5013. In order to control the rotation of the round tooth plate 503, the round tooth plate 503 can be controlled to move upward, thereby driving the movable plate 5031 to move to a position inside the movable opening 5013 outside the convex strip 5014, and then the convex strip 5014 no longer limits the movable plate 5031, thereby controlling the rotation of the round tooth plate 503, which can bring The movable plate 5031 rotates and moves in the movable opening 5013, and the movable plate 5031 will compress the spring 2 5033 at the same time. Therefore, after the spherical tooth plate 503 is loosened, the spring 2 5033 will push the movable plate 5031 to reset, thereby controlling the reset movement of the spherical tooth plate 503, and when the spherical tooth plate 503 is engaged with the outer ring nut 5021, the spring 2 5033 pushes the movable plate 5031 to ensure that the spherical tooth plate 503 is stably connected with the positioning plate 501, and the engagement between the spherical tooth plate 503 and the outer ring nut 5021 is stable, thereby avoiding the spherical tooth plate 503 and the outer ring nut 5021 from being disengaged.

[0055] Example 5: Please refer to Figure 3 、 Figure 5 、 Figure 9 and Figure 11 On the basis of the first embodiment, the assembly rod 2024 is moved in or out of the plug hole 1013 to facilitate the control of the rapid disassembly and assembly of the assembly plate 201.

[0056] Specifically, the front and rear parts of the left and right sides of the assembly plate 201 are provided with blocking holes 2014, the inner end faces of the blocking holes 2014 are provided with moving holes 2013, the inner wall of the assembly port 1012 is provided with plug holes 1013 at the position corresponding to the blocking holes 2014, and the inside of the blocking holes 2014 is provided with assembly rods 2024 plugged into the internal position of the plug holes 1013. The inner wall of the circular mouth 2011 is provided with a plurality of curved holes 2012 respectively connected to the inside of the moving holes 2013, and the end faces of the assembly rods 2024 opposite to the plug holes 1013 are fixed with the internal positions of the moving holes 2013. The movable plate 2023 has a spring 2025 fixed to the end surface of the movable plate 2023 opposite to the assembly rod 2024, which is connected to the inner end surface of the movable hole 2013. A pull rope 2021 is fixed to one side of the movable plate 2023 and passes through the inner position of the spring 2025. The other end of the pull rope 2021 passes through the curved hole 2012 and is fixedly connected to the surface side wall of the linkage plate 202. The end surface of the assembly plate 201 corresponding to the wire frame 101 is provided with a through hole 2015 connected to the inside of the circular opening 2011. The end surface of the linkage plate 202 is fixed with a T-shaped plate 2022 passing through the inner position of the through hole 2015.

[0057] When the linkage plate 202 is controlled to rotate inside the circular opening 2011, the linkage plate 202 will drive the pull rope 2021 to move in the curved hole 2012 and retract the pull rope 2021, thereby pulling the movable plate 2023 and causing the movable plate 2023 to drive the assembly rod 2024 to move out of the plug hole 1013. At this time, the assembly rod 2024 and the wire frame 101 are no longer in an assembled connection relationship, so the assembly plate 201 can be directly taken out from the assembly opening 1012 to expose the internal structure of the wire frame 101 and check whether the multiple components inside it need to be repaired or replaced. At the same time, when the movable plate 2023 is pulled by the pull rope 2021 in the movable hole 2013, the movable plate 2023 will compress the spring 1 2025. When the user releases the linkage plate 202, the spring 1025 will push the movable plate 2023 to reset and move. Therefore, before this, the assembly plate 201 is placed in the assembly opening 1012, and the blocking hole 2014 is aligned with the position of the plug hole 1013, so that the movable plate 2023 will directly push the assembly rod 2024 to reset and insert it into the plug hole 1013, thereby realizing the rapid installation of the assembly plate 201. At the same time, the T-shaped plate 2022 passes through the position of the through hole 2015, so that the wide surface of the T-shaped plate 2022 is located in the internal position of the wire frame 101. Therefore, the T-shaped plate 2022 plays a role in limiting the linkage plate 202, so that the linkage plate 202 is stably located in the circular opening 2011. At the same time, when the linkage plate 202 rotates, it will also drive the T-shaped plate 2022 to rotate synchronously.
