Description

Technical Field

[0001] The present invention relates to the technical field of bus ducts, and particularly to a highly protected and compact bus duct. Background Art

[0002] In the fields of industrial power distribution and building electricity, due to advantages such as large current-carrying capacity and compact structure, compact bus ducts are widely used in high-load power transmission and distribution scenarios. Especially in environments with mechanical vibrations such as industrial plants and high-rise buildings, the seismic stability of the bus duct connection structure has become a key technical issue;

[0003] After retrieval, a Chinese patent with the publication number CN222721083U provides a snap-in type bus duct based on modular design. By setting the rotation of gears, the first clamping rod on the movable plate enters the connection box and snaps into the first clamping groove on the groove body to clamp two bus duct modules. At the same time, the second clamping rod snaps into the second clamping groove to further clamp and fix the groove body, ensuring the contact stability of the two copper bars;

[0004] However, it is found in the use process that in working conditions with frequent vibrations such as subway operation and the start and stop of heavy equipment, the compact bus duct uses rigid bolt connections or simple elastic gaskets for shock absorption, and it is difficult to cope with multi-directional vibration impacts. Long-term vibrations easily lead to loosening at the connection, an increase in contact resistance, a sharp rise in temperature at the connector, and even arc faults, making it difficult to meet the technical requirements of electrical connection stability, mechanical structure reliability, and high-grade protection and sealing in complex vibration environments. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a highly protected and compact bus duct. The shock-absorbing member absorbs multi-directional vibration impacts, and the pressing block continuously counteracts the pressure to ensure the stable and reliable electrical connection pressure of the connector, avoiding fluctuations in contact resistance caused by vibrations. Through the cooperation of the C-shaped block and the cover plate, radial sealing is maintained to prevent dust and liquid from invading, facilitating the dispersion of vibration energy, avoiding the transmission of vibrations to the bus duct body and the internal conductor of the connector, reducing insulation layer wear, and reducing fluctuations in contact resistance.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A highly protected and compact bus duct includes a bus duct body and a connection assembly. A connector is provided between two adjacent bus duct bodies, and both ends of the connector are electrically connected to the two bus duct bodies respectively;

[0007] Insulating partitions are fixedly provided at both ends of the bus duct body respectively. Cover plates are fixedly provided on the top and bottom surfaces of the bus duct body respectively. C-shaped side plates are fixedly provided on both sides of the bus duct body, and both ends of the C-shaped side plates are fixedly connected to the inner wall of the cover plate;

[0008] The connecting component includes a connecting bottom plate and a connecting top plate. The two ends of the connecting bottom plate are respectively clamped and matched with the two cover plates located at the lower end. The bottom surface of the connecting top plate is slidably connected to the top surface of one of the cover plates. A C-shaped block is slidably connected between the connecting bottom plate and the connecting top plate. The connecting bottom plate and the connecting top plate are fixedly connected through a shock absorber. Two pressing blocks are respectively slidably connected to the inner sides of the C-shaped block, and the two pressing blocks respectively abut against the outer wall of the insulating partition.

[0009] Preferably, mounting blocks are respectively fixed at the four corners of the connecting bottom plate. Limiting blocks are respectively provided on the connecting bottom plate and the connecting top plate. The limiting blocks on the connecting bottom plate and the limiting blocks on the connecting top plate are located at different ends. A plurality of guiding grooves are formed on the bottom surface of the connecting bottom plate. The two limiting blocks are respectively clamped and matched with the corresponding connecting bottom plate and connecting top plate. Two grooves are formed on the C-shaped block, and convex blocks are slidably connected inside the grooves. The two convex blocks are respectively fixed on the connecting bottom plate and the connecting top plate.

[0010] Through the above technical solution, when the busbar trunking body is vibrated, the C-shaped block slides along the convex block, reducing the rigid impact through displacement compensation. At the same time, the guiding grooves limit the longitudinal offset, realizing the directional absorption of three-dimensional vibrations.

[0011] Preferably, sealing rings are respectively embedded at both ends of the C-shaped block. Adjusting studs are respectively threadedly connected through threaded holes in the middle parts of both ends of the C-shaped block. The inner ends of the adjusting studs are rotatably connected with pushing blocks. Two T-shaped blocks are fixedly arranged on the inner wall of the C-shaped block. The pressing blocks and the pushing blocks are respectively slidably connected with the T-shaped blocks. A plurality of first springs are fixedly arranged on the inner wall of the pushing block, and the other ends of the first springs are respectively fixedly connected with the T-shaped blocks.

[0012] Through the above technical solution, when the busbar trunking body has a slight displacement caused by vibration, the pressing block slides along the T-shaped block, and the first spring dynamically adjusts the contact pressure, avoiding the loosening of conductor contact or stress concentration caused by vibration, and suppressing the fluctuation of the contact resistance.

[0013] Preferably, a plurality of shock absorbers are provided. The shock absorber includes a base, and a connecting rod is fixedly arranged on the top surface of the base. A plurality of bases are respectively fixedly connected with the outer wall of the connecting bottom plate. A plurality of stabilizing blocks are respectively fixedly arranged on the C-shaped block and the connecting top plate. A waist-shaped hole is formed on the top surface of the stabilizing block. A first shock absorber is threadedly connected to the top surface of the connecting rod, and an adjusting rod is fixedly arranged on the top surface of the first shock absorber.

[0014] Through the above technical solution, the spring of the first shock absorber absorbs the vibration energy in the vertical direction, the damper consumes the kinetic energy, the waist-shaped hole allows the adjusting rod to slide horizontally, and with the limit of the convex block, the elastic buffering of the horizontal vibration is realized.

[0015] Preferably, the outer peripheral wall of the adjusting rod slides with the hole walls of a plurality of waist-shaped holes respectively. Two gaskets are sleeved on the outer peripheral wall of the top surface of the adjusting rod. The bottom surface of one of the gaskets is slidably connected to the top surface of the stable block located at the upper end. The upper end of the adjusting rod is threadedly connected with a hexagonal nut through external threads.

[0016] Through the above technical solution, the compression amount of the gasket is adjusted by the hexagonal nut, which is convenient for setting the initial pre-tightening force of the first shock absorber and adapting to different vibration conditions.

[0017] Preferably, a protection component is further included. The protection component includes a protective cover. An insertion block is fixedly arranged on the inner side of the protective cover. Two elastic clamping heads are fixedly arranged on the insertion block. A round block is fixedly arranged on the top surface of the connecting top plate. A slot is opened on the top surface of the round block. A second shock absorber is fixedly arranged at the bottom of the slot. Two clamping slots are opened on the outer peripheral wall of the round block. The elastic clamping heads are in clamping fit with the clamping slots.

[0018] Through the above technical solution, when an object falls onto the protective cover and causes vibration due to impact, the elastic clamping heads slide in the clamping slots, and the vibration energy is absorbed through the elastic deformation of the second shock absorber, reducing the vibration impact of the protective cover and improving the protection effect and use safety.

[0019] Preferably, a heat dissipation component is further included. The heat dissipation component includes a heat dissipation block. The heat dissipation block is in frictional contact with the C-shaped side plate. A plurality of rotating seats are fixedly arranged on the C-shaped side plate. A plug rod is rotatably connected to the rotating seat. The plug rod and the rotating seat are respectively inserted into the heat dissipation block through through holes in a plugging manner. A cross block is slidably connected to the plug rod through a first cross slot. One end of the cross block is fixedly provided with a second spring. The other end of the second spring is fixedly connected to the plug rod.

[0020] Preferably, heat dissipation pipes are respectively embedded in the heat dissipation block and the C-shaped block. The heat dissipation pipes are in a meandering shape. Adjacent two heat dissipation pipes are connected and communicated through a metal hose. A plurality of heat dissipation fins are fixedly arranged on the outer wall of the heat dissipation block. A positioning block is inserted on the plug rod. A second cross slot is opened on the positioning block. The second cross slot is in clearance fit with the cross block. A plurality of positioning slots are opened on the positioning block. The cross block is in clamping fit with the positioning slots.

[0021] Through the above technical solution, the heat dissipation pipes in the C-shaped side plate and the C-shaped block are connected in series through the metal hose. The coolant flows through the heat dissipation pipes on both sides of the C-shaped side plate in sequence through the metal hose, forming a closed circulating water path, ensuring the continuous contact between the heat dissipation block and the C-shaped side plate, stably conducting heat, and at the same time facilitating the installation and disassembly of the positioning block through the cross block through the first cross slot.

[0022] Preferably, a cold row body is provided outside one of the busbar trunking bodies. A plurality of hooks are provided on the outer peripheral wall of the cold row body. Two of the hooks located at the upper end are respectively engaged with the edges of the connecting top plate. The input end of the cold row body is communicated with a liquid inlet pipe, the output end of the cold row body is communicated with a circulating water pump, and a heat dissipation fan is installed at the outer end of the cold row body.

[0023] Through the above technical solution, after absorbing the heat of the conductor of the busbar trunking body, it flows back to the cold row body for heat exchange, and is dissipated by the heat dissipation fan. The air flow of the heat dissipation fan quickly dissipates the heat into the environment, realizing uniform heat dissipation of the busbar trunking body.

[0024] Preferably, two adjusting blocks are symmetrically fixed on the outer end of the cold row body. An active block is slidably connected to the adjusting block. The lower end of the active block is fixedly connected to the hook located at the lower end through a triangular block. The hook located at the lower end is engaged with the connecting bottom plate through a guiding groove. A rectangular groove is formed in the middle of the active block, and a third spring is fixedly installed at the upper end inside the rectangular groove. The bottom surface of the third spring is fixedly connected to the adjusting block.

[0025] Through the above technical solution, the adjusting block of the cold row body is connected to the lower hook through the active block and the triangular block. The third spring provides an elastic pre-tightening force, allowing the cold row to vibrate and displace within a suitable range along with the busbar trunking body, avoiding cracking of the pipeline caused by rigid connection, and at the same time adapting to different installation spacings.

[0026] The beneficial effects of the present invention are as follows:

[0027] 1. The shock-absorbing member forms an elastic support between the connecting bottom plate and the connecting top plate, absorbing vibration impacts in multiple directions. The C-shaped block slides between the connecting bottom plate and the connecting top plate, and the two pressing blocks dynamically abut against the outer wall of the insulating partition, dissipating vibration energy through sliding friction; the continuous counteracting pressure of the pressing blocks ensures the stable and reliable electrical connection pressure of the connector, avoiding fluctuations in contact resistance caused by vibration. The fixed connection between the C-shaped side plate and the cover plate forms a closed cavity. While allowing the connecting component to deform, the radial sealing performance is maintained through the cooperation of the C-shaped block and the cover plate, preventing dust and liquid from invading, facilitating the dispersion of vibration energy, avoiding vibration transmission to the internal conductors of the busbar trunking body and the connector, reducing insulation layer wear, and reducing fluctuations in contact resistance.

[0028] 2. The rotating adjustment stud pushes the push block to slide along the T-shaped block, compressing the first spring. Through the guiding action of the T-shaped block, the push block transfers the pressure to the pressing block, ensuring that the pressing block always tightly abuts against the outer wall of the insulating partition. When the slight displacement of the busbar trunk caused by vibration occurs, the pressing block slides along the T-shaped block, and the first spring dynamically adjusts the contact pressure through compression / elongation, avoiding the loosening of conductor contact or stress concentration caused by vibration, suppressing the fluctuation of contact resistance, and ensuring the stability of electrical connection in a vibrating environment. The spring of the first shock absorber absorbs the vibration energy in the vertical direction, the damper consumes the kinetic energy, and the waist-shaped hole allows the adjusting rod to slide horizontally. With the limit of the convex block, elastic buffering of horizontal vibration is achieved.

[0029] 3. The metal hose connects the heat dissipation pipes in the C-shaped side plate and the C-shaped block in series. The coolant flows through the heat dissipation pipes on both sides of the C-shaped side plate in sequence through the metal hose, forming a closed circulating water path; after absorbing the heat of the conductor of the busbar trunk, it flows back to the cold row body for heat exchange and is dissipated by the heat dissipation fan. The heat generated during the operation of the busbar trunk is conducted to the heat dissipation block through the C-shaped side plate. The coolant in the heat dissipation pipe absorbs heat and then heats up. When the hot liquid flows through the cold row body, the airflow of the heat dissipation fan quickly dissipates the heat into the environment, realizing uniform heat dissipation of the busbar trunk and avoiding local overheating.

Detailed implementation manners

[0052] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0053] Embodiment 1: As Figures 1 to 7 , Figure 9 and Figure 10 shown, this embodiment provides a highly protected and dense busbar trunking, which includes a busbar trunking body 100 and a connection assembly 300. A connector 200 is provided between two adjacent busbar trunking bodies 100, and both ends of the connector 200 are electrically connected to the two busbar trunking bodies 100 respectively;

[0054] Insulating partitions 101 are fixedly provided at both ends of the busbar trunking body 100 respectively, cover plates 102 are fixedly provided on the top and bottom surfaces of the busbar trunking body 100 respectively, C-shaped side plates 103 are fixedly provided on both sides of the busbar trunking body 100, and both ends of the C-shaped side plates 103 are fixedly connected to the inner walls of the cover plates 102 respectively;

[0055] The connection assembly 300 includes a connection bottom plate 301 and a connection top plate 302. Both ends of the connection bottom plate 301 are in snap-fit connection with the two cover plates 102 located at the lower end respectively. The bottom surface of the connection top plate 302 is slidably connected to the top surface of one of the cover plates 102. A C-shaped block 303 is slidably connected between the connection bottom plate 301 and the connection top plate 302. The connection bottom plate 301 and the connection top plate 302 are fixedly connected through a shock-absorbing member 304. Two pressing blocks 305 are slidably connected to the inner sides of the C-shaped block 303 respectively, and the two pressing blocks 305 are respectively abutted against the outer walls of the insulating partitions 101.

[0056] Mounting blocks 311 are fixedly provided at the four corners of the connection bottom plate 301 respectively. Limit blocks 314 are respectively provided on the connection bottom plate 301 and the connection top plate 302. The limit blocks 314 on the connection bottom plate 301 and the limit blocks 314 on the connection top plate 302 are located at different ends respectively. A plurality of guide grooves 313 are formed on the bottom surface of the connection bottom plate 301. The two limit blocks 314 are respectively in snap-fit connection with the corresponding connection bottom plate 301 and connection top plate 302. Two grooves 312 are formed on the C-shaped block 303, and convex blocks 315 are slidably connected inside the grooves 312. The two convex blocks 315 are respectively fixedly provided on the connection bottom plate 301 and the connection top plate 302; when the busbar trunking body 100 is vibrated, the C-shaped block 303 slides along the convex blocks 315, reducing the rigid impact through displacement compensation. At the same time, the guide grooves 313 limit the longitudinal offset, realizing the directional absorption of three-dimensional vibrations.

[0057] Sealing rings 306 are respectively embedded at both ends of the C-shaped block 303. Adjusting studs 307 are respectively threadedly connected to the middle parts of both ends of the C-shaped block 303 through threaded holes. The inner ends of the adjusting studs 307 are rotatably connected to push blocks 308. Two T-shaped blocks 309 are fixedly arranged on the inner wall of the C-shaped block 303. The pressing block 305 and the push block 308 are respectively slidably connected to the T-shaped blocks 309. A plurality of first springs 310 are fixedly arranged on the inner wall of the push block 308. The other ends of the first springs 310 are respectively fixedly connected to the T-shaped blocks 309. When the busbar trunking body 100 has a slight displacement due to vibration, the pressing block 305 slides along the T-shaped block 309, and the first springs 310 dynamically adjust the contact pressure, avoiding conductor contact looseness or stress concentration caused by vibration, and suppressing the fluctuation of the contact resistance.

[0058] There are a plurality of shock-absorbing members 304. The shock-absorbing member 304 includes a base 3041. A connecting rod 3042 is fixedly arranged on the top surface of the base 3041. A plurality of bases 3041 are respectively fixedly connected to the outer wall of the connecting bottom plate 301. A plurality of stabilizing blocks 3043 are respectively fixedly arranged on the C-shaped block 303 and the connecting top plate 302. A waist-shaped hole 3044 is formed on the top surface of the stabilizing block 3043. A first shock absorber 3045 is threadedly connected to the top surface of the connecting rod 3042. An adjusting rod 3046 is fixedly arranged on the top surface of the first shock absorber 3045. The spring of the first shock absorber 3045 absorbs the vibration energy in the vertical direction, and the damper consumes the kinetic energy. The waist-shaped hole 3044 allows the adjusting rod 3046 to slide horizontally, and with the limitation of the convex block 315, elastic buffering of the horizontal vibration is realized.

[0059] The outer peripheral wall of the adjusting rod 3046 slides respectively with the hole walls of a plurality of waist-shaped holes 3044. Two gaskets 3047 are sleeved on the outer peripheral wall of the top surface of the adjusting rod 3046. The bottom surface of one of the gaskets 3047 is slidably connected to the top surface of the stabilizing block 3043 located at the upper end. The upper end of the adjusting rod 3046 is threadedly connected with a hexagon nut 3048 through external threads. By adjusting the compression amount of the gasket 3047 through the hexagon nut 3048, it is convenient to set the initial pre-tightening force of the first shock absorber 3045 to adapt to different vibration conditions.

[0060] Working principle: When the busbar trunking body 100 is subjected to external vibration, the snap-fit between the connecting bottom plate 301 and the cover plate 102 allows a small amount of axial displacement. At the same time, the connecting top plate 302 slides along the top surface of the cover plate 102, and the vibration stress is released through deformation; the shock-absorbing members 304 form an elastic support between the connecting bottom plate 301 and the connecting top plate 302, absorbing the vibration impacts in multiple directions. The C-shaped block 303 slides between the connecting bottom plate 301 and the connecting top plate 302, and the two pressing blocks 305 dynamically abut against the outer wall of the insulating partition 101, dissipating the vibration energy through sliding friction;

[0061] The continuous counteracting pressure of the pressing block 305 ensures the stable and reliable electrical connection pressure of the connector 200, avoiding fluctuations in contact resistance caused by vibration. The fixed connection between the C-shaped side plate 103 and the cover plate 102 forms a closed cavity. While allowing the connection assembly 300 to deform, the cooperation between the C-shaped block 303 and the cover plate 102 maintains radial sealing, preventing dust and liquid from invading, facilitating the dispersion of vibration energy, avoiding the transmission of vibration to the internal conductors of the busbar trunking body 100 and the connector 200, reducing insulation layer wear, and reducing fluctuations in contact resistance;

[0062] The connection bottom plate 301 is fixed inside the bridge of the mounting busbar trunking body 100 through the four-corner mounting blocks 311 to fix the connection assembly 300. The convex block 315 sliding in the groove 312 guides the connection bottom plate 301 and the connection top plate 302 to move along a preset trajectory, ensuring that the deformation direction is controllable. The C-shaped block 303 slides through the groove 312 and the convex block 315, allowing it to move in the vertical and horizontal directions. When the busbar trunking body 100 is vibrated, the C-shaped block 303 slides along the convex block 315, reducing the rigid impact through displacement compensation. At the same time, the guide groove 313 restricts the longitudinal offset, achieving the directional absorption of three-dimensional vibration;

[0063] The rotating adjustment stud 307 pushes the push block 308 to slide along the T-shaped block 309, compressing the first spring 310. Through the guiding action of the T-shaped block 309, the push block 308 transmits the pressure to the pressing block 305, ensuring that the pressing block 305 always presses tightly against the outer wall of the insulating partition 101. When the vibration causes a slight displacement of the busbar trunking body 100, the pressing block 305 slides along the T-shaped block 309, and the first spring 310 dynamically adjusts the contact pressure through compression / elongation, avoiding conductor contact loosening or stress concentration caused by vibration, suppressing fluctuations in contact resistance, and ensuring the stability of electrical connection in a vibrating environment;

[0064] The lower end of the first shock absorber 3045 is fixed to the connection bottom plate 301 through the connecting rod 3042, and the upper end adjusting rod 3046 passes through the waist-shaped hole 3044 of the C-shaped block 303 and the connection top plate 302. During vibration, the spring of the first shock absorber 3045 absorbs the vibration energy in the vertical direction, and the damper consumes kinetic energy. The waist-shaped hole 3044 allows the adjusting rod 3046 to slide horizontally, and together with the limit of the convex block 315, it realizes the elastic buffering of horizontal vibration;

[0065] By adjusting the compression amount of the gasket 3047 through the hexagon nut 3048, it is convenient to set the initial pre-tightening force of the first shock absorber 3045 to adapt to different vibration conditions; The sealing rings 306 at both ends of the C-shaped block 303 are embedded in the sealing grooves of the busbar trunking body 100. When the C-shaped block 303 slides, the sealing rings 306 maintain a tight fit with the cover plate 102 through elastic deformation, ensuring that the protection level does not fail during vibration, and it is difficult for dust and water vapor to invade through the gaps of the connection assembly 300.

[0066] Example 2: As Figure 1 , Figure 2 and Figure 8 shown, this embodiment is based on the previous embodiment. The difference from the previous embodiment is that a high-protection dense busbar also includes a protection component 400. The protection component 400 includes a protective cover 401. An insertion block 402 is fixedly arranged on the inner side of the protective cover 401. Two elastic clamping heads 403 are fixedly arranged on the insertion block 402. A round block 404 is fixedly arranged on the top surface of the connecting top plate 302. A slot 405 is opened on the top surface of the round block 404. A second shock absorber 406 is fixedly arranged at the bottom of the slot 405. Two clamping slots 407 are opened on the outer peripheral wall of the round block 404. The elastic clamping heads 403 are in clamping fit with the clamping slots 407. When an object falls onto the protective cover 401 and causes vibration due to impact, the elastic clamping heads 403 slide in the clamping slots 407, and the vibration energy is absorbed through the elastic deformation of the second shock absorber 406, reducing the vibration impact of the protective cover 401 and improving the protection effect and use safety.

[0067] During use, align the insertion block 402 of the protective cover 401 with the slot 405 of the round block 404 on the connecting top plate 302. When pressing down the protective cover 401, the elastic clamping heads 403 are squeezed and contracted until they are clamped into the clamping slots 407 on the outer peripheral wall of the round block 404 to complete mechanical locking. The second shock absorber 406 provides buffering when the insertion block 402 is inserted and maintains the continuous pressing force between the elastic clamping heads 403 and the clamping slots 407;

[0068] When an external object falls or water drops onto the outer wall of the protective cover 401, the protective cover 401 protects the connector 200 and the connecting component 300. When an object falls onto the protective cover 401 and causes vibration due to impact, the elastic clamping heads 403 slide in the clamping slots 407, and the vibration energy is absorbed through the elastic deformation of the second shock absorber 406, reducing the vibration impact of the protective cover 401, reducing the loosening of the connector 200 or seal failure caused by rigid collision, and improving the protection effect and use safety;

[0069] Both the first shock absorber 3045 and the second shock absorber 406 are damping spring shock absorbers. The damping spring shock absorber includes a spring and a damping element, which are mainly used to isolate and absorb mechanical vibration energy. The spring absorbs impact energy through elastic deformation, while the damping element suppresses the oscillation when the spring rebounds, avoids resonance phenomenon, and reduces vibration transmission.

[0070] Example 3: As Figure 1 , Figure 2 , Figure 3 , Figures 9 to 14As shown, this embodiment is based on the previous embodiment, and is different from the previous embodiment in that a high-protection intensive bus duct also includes a heat dissipation component 500, and the heat dissipation component 500 includes a heat dissipation block 501. The heat dissipation block 501 is in friction contact with the C-shaped side plate 103, and a plurality of rotating seats 503 are fixedly provided on the C-shaped side plate 103. The rotating seat 503 is rotatably connected with a plug rod 504, and the plug rod 504 and the rotating seat 503 are respectively plugged and matched with the heat dissipation block 501 through through holes, and a cross block 506 is slidably connected to the plug rod 504 through a first cross groove 505, and a second spring 507 is fixedly provided at one end of the cross block 506, and the other end of the second spring 507 is fixedly connected to the plug rod 504, and heat dissipation pipes 511 are respectively embedded in the heat dissipation block 501 and the C-shaped block 303, and the heat dissipation pipes 511 are circuitous, and two adjacent heat dissipation pipes 511 are circuitous. The tubes 511 are connected to each other through a metal hose 512, a plurality of heat dissipation fins 513 are fixedly arranged on the outer wall of the heat dissipation block 501, a positioning block 508 is inserted on the insertion rod 504, a second cross groove 509 is provided on the positioning block 508, the second cross groove 509 is gap-matched with the cross block 506, a plurality of positioning grooves 510 are provided on the positioning block 508, and the cross block 506 is snap-fitted with the positioning groove 510; the heat dissipation tubes 511 in the C-shaped side plate 103 and the C-shaped block 303 are connected in series through the metal hose 512, and the coolant flows through the heat dissipation tubes 511 on both sides of the C-shaped side plate 103 in turn through the metal hose 512, forming a closed circulation water circuit, ensuring the continuous contact between the heat dissipation block 501 and the C-shaped side plate 103, stably conducting heat, and at the same time, the first cross groove 505 facilitates the installation and removal of the positioning block 508 through the cross block 506.

[0071] A cold row body 514 is provided on the outside of one of the bus duct bodies 100, and a plurality of hooks 515 are provided on the outer peripheral wall of the cold row body 514. The two hooks 515 at the upper end are respectively engaged with the edges of the connecting top plate 302. The input end of the cold row body 514 is connected to a liquid inlet pipe 521, and the output end of the cold row body 514 is connected to a circulating water pump 516. A cooling fan 517 is installed on the outer end of the cold row body 514. After absorbing the heat of the conductor of the bus duct body 100, it flows back to the cold row body 514 for heat exchange, and the heat is dissipated through the cooling fan 517. The airflow of the cooling fan 517 quickly dissipates the heat to the environment, thereby realizing uniform heat dissipation of the bus duct body 100.

[0072] On the outer end of the cold row body 514, two adjusting blocks 518 are symmetrically fixed. A movable block 522 is slidably connected to the adjusting block 518. The lower end of the movable block 522 is fixedly connected to the lower hook 515 through a triangular block 519. The lower hook 515 is in clamping fit with the connecting bottom plate 301 through a guiding groove 313. A rectangular groove 502 is formed in the middle of the movable block 522. At the upper end inside the rectangular groove 502, a third spring 520 is fixedly installed. The bottom surface of the third spring 520 is fixedly connected to the adjusting block 518. The adjusting block 518 of the cold row body 514 is connected to the lower hook 515 through the movable block 522 and the triangular block 519. The third spring 520 provides an elastic pre-tightening force, allowing the cold row to vibrate and displace within a suitable range along with the busbar trunking body 100, avoiding pipeline cracking caused by rigid connection, and at the same time adapting to different installation spacings.

[0073] During use, the cold row body 514 is clamped to the connecting top plate 302 through the upper hook 515, and the lower hook 515 is in clamping connection with the connecting bottom plate 301 through the guiding groove 313, which facilitates the installation of the cold row body 514 on the busbar trunking body 100. The circulating water pump 516 drives the coolant to flow into the cold row body 514 from the liquid inlet pipe 521, and passes through the heat dissipation pipes 511 in the C-shaped side plate 103 and the C-shaped block 303 in series through the metal hose 512. The coolant flows through the heat dissipation pipes 511 on both sides of the C-shaped side plate 103 in sequence through the metal hose 512 to form a closed circulating water path.

[0074] After absorbing the heat of the conductor of the busbar trunking body 100, it flows back to the cold row body 514 for heat exchange, and is dissipated by the heat dissipation fan 517. The heat generated during the operation of the busbar trunking body 100 is conducted to the heat dissipation block 501 through the C-shaped side plate 103. The coolant in the heat dissipation pipe 511 absorbs heat and then heats up. When the hot liquid flows through the cold row body 514, the airflow of the heat dissipation fan 517 quickly dissipates the heat into the environment, realizing uniform heat dissipation of the busbar trunking body 100 and avoiding local overheating.

[0075] The heat dissipation block 501 is inserted into the C-shaped side plate 103 through the rotating seat 503 and the insertion rod 504. The cross block 506 is inserted into the positioning groove 510 of the positioning block 508, so that the heat dissipation block 501 is closely attached to the surface of the C-shaped side plate 103. During vibration, the cross block 506 slides in the second cross groove 509, and the displacement is compensated by the second spring 507, improving the stability in the vibration environment, ensuring the continuous contact between the heat dissipation block 501 and the C-shaped side plate 103, stably conducting heat, and at the same time facilitating the installation and disassembly of the positioning block 508 through the cross block 506 through the first cross groove 505.

[0076] The adjusting block 518 of the cold row body 514 is connected to the lower hook 515 through the movable block 522 and the triangular block 519. The third spring 520 provides an elastic pre-tightening force, allowing the cold row to vibrate and displace within a suitable range along with the busbar trunking body 100, avoiding pipeline cracking caused by rigid connection. At the same time, it adapts to different installation spacings and accommodates the layouts of different busbar trunking bodies 100.

[0077] Working principle: When the busbar trunking body 100 is subjected to external vibration, the snap-fit connection between the connecting bottom plate 301 and the cover plate 102 allows for a small amount of axial displacement. At the same time, the connecting top plate 302 slides along the top surface of the cover plate 102, releasing the vibration stress through deformation; the shock-absorbing member 304 forms an elastic support between the connecting bottom plate 301 and the connecting top plate 302, absorbing multi-directional vibration impacts. The C-shaped block 303 slides between the connecting bottom plate 301 and the connecting top plate 302, and the two pressing blocks 305 dynamically abut against the outer wall of the insulating partition 101, dissipating the vibration energy through sliding friction;

[0078] The continuous counteracting pressure of the pressing block 305 ensures the stable and reliable electrical connection pressure of the connector 200, avoiding fluctuations in contact resistance caused by vibration. The fixed connection between the C-shaped side plate 103 and the cover plate 102 forms a closed cavity. While allowing the connecting component 300 to deform, it maintains the radial sealing performance through the cooperation of the C-shaped block 303 and the cover plate 102, preventing dust and liquid from entering, facilitating the dispersion of vibration energy, avoiding the transmission of vibration to the internal conductors of the busbar trunking body 100 and the connector 200, reducing the wear of the insulating layer, and reducing the fluctuation of contact resistance;

[0079] The connecting bottom plate 301 is fixed inside the bridge for installing the busbar trunking body 100 through the four-corner mounting blocks 311, fixing the connecting component 300. The convex block 315 sliding in the groove 312 guides the connecting bottom plate 301 and the connecting top plate 302 to move along a preset trajectory, ensuring that the deformation direction is controllable. The C-shaped block 303 slides through the groove 312 and the convex block 315, allowing it to move in the vertical and horizontal directions. When the busbar trunking body 100 is vibrated, the C-shaped block 303 slides along the convex block 315, reducing the rigid impact through displacement compensation. At the same time, the guiding groove 313 restricts the longitudinal offset, achieving the directional absorption of three-dimensional vibration;

[0080] The rotating adjustment stud 307 pushes the push block 308 to slide along the T-shaped block 309, compressing the first spring 310, so that the push block 308 transfers the pressure to the pressing block 305 through the guiding action of the T-shaped block 309, ensuring that the pressing block 305 always abuts tightly against the outer wall of the insulating partition 101. When the vibration causes a slight displacement of the busbar trunking body 100, the pressing block 305 slides along the T-shaped block 309, and the first spring 310 dynamically adjusts the contact pressure through compression / elongation, avoiding conductor contact loosening or stress concentration caused by vibration, suppressing the fluctuation of contact resistance, and ensuring the stability of electrical connection in a vibrating environment;

[0081] The lower end of the first shock absorber 3045 is fixed to the connecting bottom plate 301 through the connecting rod 3042. The upper end adjusting rod 3046 passes through the waist-shaped hole 3044 of the C-shaped block 303 and the connecting top plate 302. During vibration, the spring of the first shock absorber 3045 absorbs the vibration energy in the vertical direction, and the damper consumes the kinetic energy. The waist-shaped hole 3044 allows the adjusting rod 3046 to slide horizontally. With the limit of the convex block 315, elastic buffering of horizontal vibration is achieved;

[0082] The compression amount of the gasket 3047 is adjusted by the hexagon nut 3048, which facilitates setting the initial pre-tightening force of the first shock absorber 3045 to adapt to different vibration conditions; The sealing rings 306 at both ends of the C-shaped block 303 are embedded in the sealing grooves of the busbar trunk body 100. When the C-shaped block 303 slides, the sealing rings 306 maintain close fit with the cover plate 102 through elastic deformation, ensuring that the protection level does not fail during vibration, and it is difficult for dust and water vapor to invade through the gaps of the connecting component 300.

[0083] During use, align the insertion block 402 of the protective cover 401 with the slot 405 of the round block 404 on the connecting top plate 302. When pressing down the protective cover 401, the elastic chuck 403 is squeezed and contracted until it snaps into the slot 407 on the outer peripheral wall of the round block 404 to complete mechanical locking. The second shock absorber 406 provides buffering when the insertion block 402 is inserted and maintains the continuous pressing force between the elastic chuck 403 and the slot 407;

[0084] When external objects fall or water droplets drip onto the outer wall of the protective cover 401, the protective cover 401 protects the connector 200 and the connecting component 300. When an object falls onto the protective cover 401 and causes vibration due to impact, the elastic chuck 403 slides in the slot 407, and the vibration energy is absorbed through the elastic deformation of the second shock absorber 406, reducing the vibration impact of the protective cover 401 and reducing the loosening or sealing failure of the connector 200 caused by rigid collision, improving the protection effect and use safety.

[0085] During use, the cold row body 514 is clamped to the connecting top plate 302 through the upper hook 515, and the lower hook 515 is clamped to the connecting bottom plate 301 through the guide groove 313, which facilitates the installation of the cold row body 514 on the busbar trunk body 100. The circulating water pump 516 drives the coolant to flow into the cold row body 514 from the liquid inlet pipe 521, and the coolant is connected in series with the heat dissipation pipes 511 in the C-shaped side plate 103 and the C-shaped block 303 through the metal hose 512. The coolant flows through the heat dissipation pipes 511 on both sides of the C-shaped side plate 103 in sequence through the metal hose 512 to form a closed circulating water path;

[0086] After absorbing the heat of the conductor of the busbar trunking body 100, it flows back to the cold plate body 514 for heat exchange, and is dissipated by the cooling fan 517. The heat generated during the operation of the busbar trunking body 100 is conducted to the heat dissipation block 501 through the C-shaped side plate 103. The coolant in the heat dissipation pipe 511 absorbs heat and then heats up. When the hot liquid flows through the cold plate body 514, the airflow of the cooling fan 517 quickly dissipates the heat into the environment, realizing uniform heat dissipation of the busbar trunking body 100 and avoiding local overheating;

[0087] The heat dissipation block 501 is inserted into the C-shaped side plate 103 through the rotating seat 503 and the insertion rod 504. The cross block 506 is snapped into the positioning groove 510 of the positioning block 508, so that the heat dissipation block 501 is closely attached to the surface of the C-shaped side plate 103. During vibration, the cross block 506 slides in the second cross groove 509, and the displacement is compensated by the second spring 507, improving the stability in the vibration environment, ensuring the continuous contact between the heat dissipation block 501 and the C-shaped side plate 103, and stably conducting heat. At the same time, the installation and disassembly of the positioning block 508 through the cross block 506 are facilitated through the first cross groove 505;

[0088] The adjusting block 518 of the cold plate body 514 is connected to the lower hook 515 through the movable block 522 and the triangular block 519. The third spring 520 provides an elastic pre-tightening force, allowing the cold plate to vibrate and displace with the busbar trunking body 100 within a suitable range, avoiding pipeline cracking caused by rigid connection, and at the same time adapting to different installation distances and different layouts of the busbar trunking body 100.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
