[0002] In the field of industrial power distribution and building electrical engineering, dense bus ducts are widely used in high-load power transmission and distribution scenarios due to their large current carrying capacity and compact structure. Especially in environments with mechanical vibration such as industrial plants and high-rise buildings, the seismic stability of bus duct connection structures has become a key technical issue. After searching, the Chinese patent with the announcement number CN222721083U provides a modular design-based snap-in bus duct. By rotating the gear, the first clamping rod on the movable plate enters the connection box and is clamped into the first clamping slot on the duct body, so that the two bus duct modules are clamped. At the same time, the second clamping rod is clamped into the second clamping slot, and the duct body is further clamped and fixed to ensure the contact stability of the two copper bars. However, during use, it was found that under the frequent vibration conditions of subway operation and the start-up and shutdown of heavy equipment, the dense bus duct using rigid bolt connections or simple elastic gaskets for shock absorption is difficult to cope with multi-directional vibration impacts. Long-term vibration can easily lead to loose connections, increased contact resistance, and a sharp increase in temperature at the connector, and even cause arc faults.

[0022] Beneficial effects of the present invention: 1. The shock absorber forms an elastic support between the connection bottom plate and the connection top plate to absorb multi-directional vibration impacts. The C-shaped block slides between the connection bottom plate and the connection top plate. The two pressure blocks dynamically abut along the outer wall of the insulating partition to dissipate vibration energy through sliding friction. The continuous offset pressure of the pressure block ensures that the electrical connection pressure of the connector is stable and reliable, avoiding vibration-induced contact resistance fluctuations. The fixed connection between the C-shaped side plate and the cover plate forms a closed cavity. While allowing the connection component to deform, the radial sealing is maintained through the cooperation of the C-shaped block and the cover plate to prevent dust and liquid intrusion, facilitate the dispersion of vibration energy, avoid vibration transmission to the bus duct body and the internal conductor of the connector, reduce insulation layer wear, and reduce contact resistance fluctuations.

[0023] 2. Rotate the adjusting stud to push the push block to slide along the T-block, compress the first spring, and allow the push block to transfer pressure to the pressure block through the guiding effect of the T-block, ensuring that the pressure block always presses against the outer wall of the insulating partition. When the bus duct body is slightly displaced due to vibration, the pressure block slides along the T-block, and the first spring dynamically adjusts the contact pressure through compression / extension to avoid loose conductor contact or stress concentration caused by vibration, suppresses contact resistance fluctuations, and ensures the stability of electrical connection under vibration environment. The spring of the first shock absorber absorbs vertical vibration energy, the damper consumes kinetic energy, and the waist hole allows the adjustment rod to slide horizontally, cooperating with the limit of the protrusion to achieve elastic buffering of horizontal vibration.

[0024] 3. The metal hose is connected in series with the heat pipes in the C-shaped side plate and the C-shaped block. The coolant flows through the heat pipes on both sides of the C-shaped side plate through the metal hose in turn to form a closed circulation water circuit; after absorbing the heat of the conductor of the bus duct body, it flows back to the radiator body for heat exchange and is dissipated through the cooling fan. The heat generated during the operation of the bus duct body is transferred to the heat dissipation block through the C-shaped side plate. The coolant in the heat pipe absorbs the heat and heats up. When the hot liquid flows through the radiator body, the airflow of the cooling fan quickly dissipates the heat to the environment, thereby achieving uniform heat dissipation of the bus duct body and avoiding local overheating.

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] Embodiment 1: Figures 1 to 7 , Fig. 9 and Fig.10 As shown, this embodiment provides a high-protection intensive bus duct, including a bus duct body 100 and a connection assembly 300, a connector 200 is provided between two adjacent bus duct bodies 100, and two ends of the connector 200 are electrically connected to the two bus duct bodies 100 respectively; Insulating partitions 101 are fixedly provided at both ends of the bus duct body 100, and cover plates 102 are fixedly provided at the top and bottom surfaces of the bus duct body 100, and C-shaped side plates 103 are fixedly provided at both sides of the bus duct body 100, and both ends of the C-shaped side plates 103 are fixedly connected to the inner wall of the cover plate 102; The connecting assembly 300 includes a connecting bottom plate 301 and a connecting top plate 302. The two ends of the connecting bottom plate 301 are respectively snap-fitted with the two cover plates 102 located at the lower end. The bottom surface of the connecting 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 connecting bottom plate 301 and the connecting top plate 302. The connecting bottom plate 301 and the connecting top plate 302 are fixedly connected by a shock absorber 304. Two pressing blocks 305 are slidably connected inside the C-shaped block 303, and the two pressing blocks 305 are respectively abutted against the outer wall of the insulating partition 101.

[0029] Mounting blocks 311 are fixed at the four corners of the connecting bottom plate 301, and limit blocks 314 are fixed on the top surface of one end of the connecting bottom plate 301 and the bottom surface of one end of the connecting top plate 302. A plurality of guide grooves 313 are provided on the bottom surface of the connecting bottom plate 301. Two limit blocks 314 are respectively engaged with the corresponding connecting bottom plate 301 and the connecting top plate 302. Two grooves 312 are provided on the C-shaped block 303. A protrusion 315 is slidably connected inside the groove 312. The two protrusions 315 are respectively fixed on the connecting bottom plate 301 and the connecting top plate 302. When the bus duct body 100 is vibrated, the C-shaped block 303 slides along the protrusion 315 to reduce the rigid impact through displacement compensation. At the same time, the guide groove 313 limits the longitudinal displacement to achieve directional absorption of three-dimensional vibration.

[0030] Sealing rings 306 are embedded at both ends of the C-shaped block 303, and adjusting studs 307 are threadedly connected to the middle of the two ends of the C-shaped block 303 through threaded holes. The inner end of the adjusting stud 307 is rotatably connected to a push block 308. Two T-shaped blocks 309 are fixedly provided on the inner wall of the C-shaped block 303. The pressure block 305 and the push block 308 are slidably connected to the T-shaped block 309 respectively. A plurality of first springs 310 are fixedly provided on the inner wall of the push block 308, and the other ends of the first springs 310 are fixedly connected to the T-shaped blocks 309 respectively. When the bus duct body 100 is slightly displaced due to vibration, the pressure block 305 slides along the T-shaped block 309, and the first spring 310 dynamically adjusts the contact pressure to avoid loose contact or stress concentration of the conductor caused by vibration, thereby suppressing contact resistance fluctuations.

[0031] There are multiple shock absorbers 304, which include a base 3041. A connecting rod 3042 is fixedly arranged on the bottom surface of the base 3041. The multiple bases 3041 are respectively fixedly connected to the outer wall of the connecting bottom plate 301. A multiple stabilizing blocks 3043 are respectively fixedly arranged on the C-shaped block 303 and the connecting top plate 302. A waist hole 3044 is opened 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 vibration energy in the vertical direction, and the damper consumes kinetic energy. The waist hole 3044 allows the adjusting rod 3046 to slide horizontally, and cooperates with the limiting function of the protrusion 315 to achieve elastic buffering of horizontal vibration.

[0032] The outer peripheral walls of the adjusting rod 3046 slide respectively with the hole walls of the multiple waist holes 3044, and 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, and the upper end of the adjusting rod 3046 is threadedly connected with a hexagonal nut 3048 through an external thread; the compression amount of the gasket 3047 is adjusted by the hexagonal nut 3048, which facilitates the setting of the initial preload force of the first shock absorber 3045 to adapt to different vibration working conditions.

[0033] Working principle: When the bus duct body 100 is subjected to external vibration, the snap-fitting of the connecting bottom plate 301 and the cover plate 102 allows a slight axial displacement, and 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 absorber 304 forms an elastic support between the connecting bottom plate 301 and the connecting top plate 302 to absorb multi-directional vibration impact, 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 along the outer wall of the insulating partition 101 to dissipate the vibration energy through sliding friction; The continuous offsetting pressure of the pressing block 305 ensures that the electrical connection pressure of the connector 200 is stable and reliable, and avoids contact resistance fluctuations 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 component 300 to deform, the radial sealing is maintained through the cooperation between the C-shaped block 303 and the cover plate 102 to prevent dust and liquid from intruding, facilitate the dispersion of vibration energy, avoid vibration transmission to the internal conductors of the bus duct body 100 and the connector 200, reduce the wear of the insulation layer, and reduce the contact resistance fluctuation; The connecting bottom plate 301 is fixed to the inside of the bridge frame where the bus duct body 100 is installed through the four-corner mounting blocks 311 to fix the connecting assembly 300. The protrusion 315 sliding in the groove 312 guides the connecting bottom plate 301 and the connecting top plate 302 to move along a preset track to ensure that the deformation direction is controllable. The C-shaped block 303 slides with the protrusion 315 through the groove 312, allowing it to move in the vertical direction and the horizontal direction. When the bus duct body 100 is vibrated, the C-shaped block 303 slides along the protrusion 315 to reduce the rigid impact through displacement compensation. At the same time, the guide groove 313 limits the longitudinal offset to achieve directional absorption of three-dimensional vibration. 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 transmits the pressure to the pressure block 305 through the guiding effect of the T-shaped block 309, ensuring that the pressure block 305 always presses against the outer wall of the insulating partition 101. When the bus duct body 100 is slightly displaced due to vibration, the pressure block 305 slides along the T-shaped block 309, and the first spring 310 dynamically adjusts the contact pressure through compression / extension, avoiding loose contact or stress concentration of the conductor caused by vibration, suppressing the fluctuation of contact resistance, and ensuring the stability of the electrical connection under the vibration environment; The lower end of the first shock absorber 3045 is fixed to the connecting bottom plate 301 through the connecting rod 3042, and the upper end adjusting rod 3046 passes through the C-shaped block 303 and the waist hole 3044 connecting the top plate 302. When vibrating, the spring of the first shock absorber 3045 absorbs the vertical vibration energy, and the damper consumes kinetic energy. The waist hole 3044 allows the adjusting rod 3046 to slide horizontally, and cooperates with the limit of the protrusion 315 to achieve elastic buffering of horizontal vibration; The compression amount of the gasket 3047 is adjusted by the hexagonal nut 3048, which facilitates the setting of the initial preload 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 groove of the bus duct body 100. When the C-shaped block 303 slides, the sealing ring 306 maintains a close fit with the cover plate 102 through elastic deformation, ensuring that the protection level does not fail during vibration, and dust and water vapor are difficult to invade through the gap of the connecting component 300.

[0034] Embodiment 2: Figure 1 , Figure 2 and Figure 8As 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 protection component 400, and the protection component 400 includes a protective cover 401, a plug block 402 is fixedly arranged inside the protective cover 401, and two elastic clamps 403 are fixedly arranged on the plug block 402, a round block 404 is fixedly arranged on the top surface of the connecting top plate 302, a slot 405 is provided on the top surface of the round block 404, and a second shock absorber 406 is fixedly arranged at the bottom of the slot 405, and two clamping grooves 407 are provided on the outer peripheral wall of the round block 404, and the elastic clamp 403 is clamped with the clamping groove 407; when an object falls onto the protective cover 401 and causes vibration due to impact, the elastic clamp 403 slides in the clamping groove 407, and the vibration energy is absorbed by the elastic deformation of the second shock absorber 406, thereby reducing the vibration impact of the protective cover 401 and improving the protection effect and safety of use.

[0035] When in use, align the insert block 402 of the protective cover 401 with the slot 405 of the round block 404 connected to the top plate 302. When the protective cover 401 is pressed down, the elastic clamp 403 is squeezed and contracted until it is clamped into the clamping groove 407 of the outer peripheral wall of the round block 404, completing the mechanical locking. The second shock absorber 406 provides buffering when the insert block 402 is inserted, and maintains the continuous pressing force between the elastic clamp 403 and the clamping groove 407. When external objects fall or water drops onto the outer wall of the protective cover 401, the protective cover 401 protects the connector 200 and the connection assembly 300. When objects fall onto the protective cover 401 and cause vibration due to impact, the elastic clamp 403 slides in the clamping groove 407, and absorbs the vibration energy through the elastic deformation of the second shock absorber 406, thereby slowing down the vibration impact of the protective cover 401, reducing the loosening of the connector 200 or the failure of the seal caused by the rigid collision, and improving the protection effect and the safety of use; The first shock absorber 3045 and the second shock absorber 406 are both damping spring shock absorbers, which include a spring and a damping element, and 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 of the spring during rebound, avoids resonance, and reduces vibration transmission.

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.

[0038] The outer end of the radiator body 514 is symmetrically structured and fixed with two adjustment blocks 518. A movable block 522 is slidably connected to the adjustment block 518. The lower end of the movable block 522 is connected and fixed to the hook 515 at the lower end through a triangular block 519. The hook 515 at the lower end is snap-fitted with the connecting bottom plate 301 through a guide groove 313. A rectangular groove 502 is opened in the middle of the movable block 522. A third spring 520 is fixedly arranged at the upper end of the rectangular groove 502. The bottom surface of the third spring 520 is fixedly connected to the adjustment block 518. The adjustment block 518 of the radiator body 514 is connected to the lower end hook 515 through the movable block 522 and the triangular block 519. The third spring 520 provides an elastic preload, allowing the radiator to vibrate and displace with the bus duct body 100 within a suitable range, thereby avoiding pipeline cracking caused by rigid connection and adapting to different installation spacings.

[0039] When in use, the radiator body 514 is clamped to the connecting top plate 302 through the upper end hook 515, and the lower end hook 515 is clamped to the connecting bottom plate 301 through the guide groove 313, which facilitates the installation of the radiator body 514 on the bus duct body 100. The circulating water pump 516 drives the coolant to flow from the liquid inlet pipe 521 into the radiator body 514, and the metal hose 512 is connected in series to the C-shaped side plate 103 and the heat dissipation pipe 511 in the C-shaped block 303. The coolant flows through the metal hose 512 in sequence through the heat dissipation pipes 511 on both sides of the C-shaped side plate 103 to form a closed circulation water circuit; After absorbing the heat of the conductor of the bus duct body 100, it flows back to the radiator body 514 for heat exchange, and dissipates heat through the cooling fan 517. The heat generated during the operation of the bus duct body 100 is transferred to the heat dissipation block 501 through the C-shaped side plate 103. The coolant in the heat dissipation pipe 511 absorbs the heat and heats up. When the hot liquid flows through the radiator body 514, the airflow of the cooling fan 517 quickly dissipates the heat to the environment, thereby achieving uniform heat dissipation of the bus duct body 100 and avoiding local overheating. The heat sink 501 is plugged into the C-shaped side plate 103 through the rotating seat 503 and the plug rod 504, and the cross block 506 is inserted into the positioning groove 510 of the positioning block 508, so that the heat sink 501 is closely attached to the surface of the C-shaped side plate 103. When vibrating, the cross block 506 slides in the second cross groove 509, and the displacement is compensated by the second spring 507, thereby improving the stability under the vibration environment, ensuring the continuous contact between the heat sink 501 and the C-shaped side plate 103, and stably conducting heat. At the same time, the first cross groove 505 facilitates the installation and removal of the positioning block 508 through the cross block 506; The adjustment block 518 of the radiator body 514 is connected to the lower end hook 515 through the movable block 522 and the triangular block 519. The third spring 520 provides elastic preload force, allowing the radiator to vibrate and displace with the bus duct body 100 within a suitable range, avoiding pipeline cracking caused by rigid connection. At the same time, it adapts to different installation spacings and adapts to the layout of different bus duct bodies 100.

[0040] Working principle: When the bus duct body 100 is subjected to external vibration, the snap-fitting of the connecting bottom plate 301 and the cover plate 102 allows a slight axial displacement, and 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 absorber 304 forms an elastic support between the connecting bottom plate 301 and the connecting top plate 302 to absorb multi-directional vibration impact, 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 along the outer wall of the insulating partition 101 to dissipate the vibration energy through sliding friction; The continuous offsetting pressure of the pressing block 305 ensures that the electrical connection pressure of the connector 200 is stable and reliable, and avoids contact resistance fluctuations 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 component 300 to deform, the radial sealing is maintained through the cooperation between the C-shaped block 303 and the cover plate 102 to prevent dust and liquid from intruding, facilitate the dispersion of vibration energy, avoid vibration transmission to the internal conductors of the bus duct body 100 and the connector 200, reduce the wear of the insulation layer, and reduce the contact resistance fluctuation; The connecting bottom plate 301 is fixed to the inside of the bridge frame where the bus duct body 100 is installed through the four-corner mounting blocks 311 to fix the connecting assembly 300. The protrusion 315 sliding in the groove 312 guides the connecting bottom plate 301 and the connecting top plate 302 to move along a preset track to ensure that the deformation direction is controllable. The C-shaped block 303 slides with the protrusion 315 through the groove 312, allowing it to move in the vertical direction and the horizontal direction. When the bus duct body 100 is vibrated, the C-shaped block 303 slides along the protrusion 315 to reduce the rigid impact through displacement compensation. At the same time, the guide groove 313 limits the longitudinal offset to achieve directional absorption of three-dimensional vibration. 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 transmits the pressure to the pressure block 305 through the guiding effect of the T-shaped block 309, ensuring that the pressure block 305 always presses against the outer wall of the insulating partition 101. When the bus duct body 100 is slightly displaced due to vibration, the pressure block 305 slides along the T-shaped block 309, and the first spring 310 dynamically adjusts the contact pressure through compression / extension, avoiding loose contact or stress concentration of the conductor caused by vibration, suppressing the fluctuation of contact resistance, and ensuring the stability of the electrical connection under the vibration environment; The lower end of the first shock absorber 3045 is fixed to the connecting bottom plate 301 through the connecting rod 3042, and the upper end adjusting rod 3046 passes through the C-shaped block 303 and the waist hole 3044 connecting the top plate 302. When vibrating, the spring of the first shock absorber 3045 absorbs the vertical vibration energy, and the damper consumes kinetic energy. The waist hole 3044 allows the adjusting rod 3046 to slide horizontally, and cooperates with the limit of the protrusion 315 to achieve elastic buffering of horizontal vibration; The compression amount of the gasket 3047 is adjusted by the hexagonal nut 3048, which facilitates the setting of the initial preload 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 groove of the bus duct body 100. When the C-shaped block 303 slides, the sealing ring 306 maintains a close fit with the cover plate 102 through elastic deformation, ensuring that the protection level does not fail during vibration, and dust and water vapor are difficult to invade through the gap of the connecting component 300.

[0041] When in use, align the insert block 402 of the protective cover 401 with the slot 405 of the round block 404 connected to the top plate 302. When the protective cover 401 is pressed down, the elastic clamp 403 is squeezed and contracted until it is clamped into the clamping groove 407 of the outer peripheral wall of the round block 404, completing the mechanical locking. The second shock absorber 406 provides buffering when the insert block 402 is inserted, and maintains the continuous pressing force between the elastic clamp 403 and the clamping groove 407. When external objects fall or water drops onto the outer wall of the protective cover 401, the protective cover 401 protects the connector 200 and the connecting assembly 300. When objects fall onto the protective cover 401 and cause vibration due to the impact, the elastic clamp head 403 slides in the clamping groove 407, and the elastic deformation of the second shock absorber 406 absorbs the vibration energy, thereby reducing the vibration impact of the protective cover 401, reducing the loosening of the connector 200 or the failure of the seal due to rigid collision, and improving the protection effect and safety of use.

[0042] When in use, the radiator body 514 is clamped to the connecting top plate 302 through the upper end hook 515, and the lower end hook 515 is clamped to the connecting bottom plate 301 through the guide groove 313, which facilitates the installation of the radiator body 514 on the bus duct body 100. The circulating water pump 516 drives the coolant to flow from the liquid inlet pipe 521 into the radiator body 514, and the metal hose 512 is connected in series to the C-shaped side plate 103 and the heat dissipation pipe 511 in the C-shaped block 303. The coolant flows through the metal hose 512 in sequence through the heat dissipation pipes 511 on both sides of the C-shaped side plate 103 to form a closed circulation water circuit; After absorbing the heat of the conductor of the bus duct body 100, it flows back to the radiator body 514 for heat exchange, and dissipates heat through the cooling fan 517.
