Description

Technical Field

[0001] This invention belongs to the field of busbar trunking technology, and specifically relates to a dense busbar trunking. Background Technology

[0002] Compact busbar trunking is a type of busbar trunking suitable for AC three-phase four-wire and three-phase five-wire systems with a frequency of 50-60Hz, a rated voltage up to 690V, and a rated operating current of 250-5000A. It serves as an auxiliary device for power distribution equipment in industrial and mining enterprises, institutions, and high-rise buildings, and is particularly suitable for the renovation of workshops and old enterprises.

[0003] When in use, if the internal temperature of the busbar trunking is too high, the conductive copper busbars inside the busbar trunking will be overheated, affecting its service life. Currently, the cooling of busbar trunking is generally achieved through passive cooling, which is relatively slow. Moreover, after long-term use, the busbar trunking will accumulate dust, which will also hinder the cooling process. Therefore, a high-density busbar trunking is proposed. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] Given the following technical problems in the existing technology: the current busbar cooling is generally achieved through passive cooling, which is relatively slow, and the busbar will accumulate dust after long-term use, which will also hinder the cooling process.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a high-density busbar trunking system, comprising,

[0007] The outer casing has several cooling fins installed on both sides for auxiliary cooling of the outer casing.

[0008] An active cooling component is installed on the left and right side walls and the top of the housing. The active cooling component includes an active cooling unit and a circulation pipe unit. The active cooling unit is installed on the top of the housing and is connected to the circulation pipe units arranged on both sides of the housing.

[0009] A transmission processing assembly is installed on both sides of the housing. The transmission processing assembly includes a transmission unit and a movable processing unit. Several transmission units are evenly installed on the two side walls of the housing and are connected to the circulation pipeline unit. Several movable processing units are installed and connected to the corresponding transmission units.

[0010] Furthermore, the cooling plates located on the same side are divided into two groups and distributed vertically, with space between the two groups of cooling plates, and the transmission unit and the movable processing unit are installed between the two groups of cooling plates.

[0011] By adopting the above technical solution, cooling plates are used to assist in cooling the interior of the casing. The space between the cooling plates facilitates the installation and operation of other transmission units and active processing units.

[0012] Furthermore, the active cooling unit includes a central shell installed on the top of the outer casing. One side of the central shell is connected to a second connection channel, and the other end of the second connection channel is connected to a pump body. The pump body communicates with the inside of the cooling shell, and a semiconductor cooler is installed in the cooling shell.

[0013] By adopting the above technical solution, a centralized shell is used to concentrate the coolant and a dispersed coolant. The pump body cools the coolant flowing into the cooling shell and then transports it to the centralized shell for centralized dispersion through the connecting channel two.

[0014] Furthermore, the circulating pipeline unit includes a conveying channel 1 connected to both sides of the central shell. Several connecting channels 1 are installed on the side of the conveying channel 1 near the shell. Several vertically distributed cooling cavities are opened on both sides of the shell. Input channels are connected to both sides of the cooling shell. Several branch pipes 2 are installed on the side of the input channels near the shell. The connecting channels 1 are respectively connected to one end of the corresponding cooling cavity, and the branch pipes 2 are respectively connected to the other end of the corresponding cooling cavity.

[0015] The cooling cavity, located in a transverse plane, is divided into two sections and connected by a transmission unit.

[0016] By adopting the above technical solution, the coolant can be circulated using the circulating pipeline unit. After being diverted from the conveying channel one through the central shell, the coolant is transported to the cooling chamber through the connecting channel one connected to the corresponding cooling chamber. Then, the liquid flows to the transmission unit, which triggers the movement of the transmission unit. After that, the liquid is transported from the cooling chamber to the input channel and moves into the cooling shell. The cooling shell cools the liquid, and this cycle continues.

[0017] Furthermore, the transmission unit includes several annular shells installed on the side wall of the outer casing. Arc-shaped channels are installed on both the front and rear sides of the annular shells. A rotating shaft is rotatably connected in the annular shell. Several annularly spaced traction plates are installed on one end of the rotating shaft located in the annular shell. A fan is fixedly connected to one end of the rotating shaft protruding from the annular shell. One end of a connecting rod is fixedly connected to the outer wall of the annular shell. A fixed cylinder is fixedly connected to the other end of the connecting rod. Several annularly spaced air inlets are opened on the rear side of the fixed cylinder.

[0018] By adopting the above technical solution, when the liquid moves through the cooling cavity, a traction force is generated. When the liquid moves into the annular shell, it flows in the annular shell, which in turn drives the rotation of the traction plate. When the traction plate rotates, it drives the rotation of the rotating shaft, which in turn drives the fan and gear one to rotate. The rotation of the fan will drive the movement of the airflow, which can accelerate the displacement of the airflow and help to cool down.

[0019] Furthermore, one end of the arc-shaped channel is connected to the annular shell, and the other end of the arc-shaped channel is connected to the corresponding cooling cavity, which is installed between two adjacent cooling plates.

[0020] By adopting the above technical solution, the two cooling cavities are connected by an arc-shaped channel and an annular shell to form a circulation and generate power. The cooling cavities are installed between two adjacent cooling plates and can cool the outer shell for heat exchange.

[0021] Furthermore, the active processing unit includes several reciprocating screws rotatably connected to the side wall of the outer casing and a gear one mounted on the outside of the rotating shaft. A moving block is threaded onto the reciprocating screw, and an outer cylinder is fixedly connected to the top of the moving block. The outer cylinder is sleeved on the outside of the fixed cylinder. Exhaust plates are fixedly connected to both sides of the outer cylinder. An exhaust cavity is opened inside the exhaust plate. Two exhaust ports are opened on the side wall of the exhaust plate away from the outer casing, distributed vertically. A fixing frame is installed on the side wall of the outer casing, and a gear two is installed on the reciprocating screw.

[0022] By adopting the above technical solution, the rotation of gear one will drive the rotation of gear two in the transmission connection. The rotation of gear two will drive the rotation of the reciprocating screw, which in turn will drive the moving block to move on the reciprocating screw. The moving block will drive the outer cylinder to move back and forth, and the outer cylinder will drive the connected exhaust plate to move. In this way, while the exhaust plate is moving, the airflow generated by the fan will be discharged through the exhaust cavity of the exhaust plate. The cooling plate is in contact with the exhaust plate, and when the exhaust plate moves, it can sweep the dust off the cooling plate. Then the exhaust cavity will blow air to blow away the swept dust. At the same time, the movement of the airflow can assist in cooling and accelerate the movement of the airflow.

[0023] Furthermore, the end of the reciprocating screw away from the outer shell is rotatably connected to the fixed frame, and the inner wall of the outer cylinder is slidably connected to the outer wall of the fixed cylinder and is sealed.

[0024] By adopting the above technical solution, the reciprocating screw is supported by a fixed frame, making the rotation of the reciprocating screw more stable. The outer cylinder can move on the fixed cylinder, which in turn drives the movement of the exhaust plate.

[0025] Furthermore, several of the first gears and several of the second gears are connected by the same toothed belt drive, and the exhaust plate is located between two vertically adjacent cooling plates.

[0026] By adopting the above technical solution, several gears are connected by the same toothed belt. In this way, when the liquid drives the traction plate to rotate through the annular shell, the traction force is concentrated on the toothed belt, thus ensuring uniform rotation and concentrating the force.

[0027] Furthermore, the upper and lower side walls of the exhaust plate are in contact with the outer walls of the corresponding cooling plates, the end of the exhaust plate connected to the outer cylinder is through-hole, and the end of the exhaust plate away from the outer cylinder is sealed.

[0028] By adopting the above technical solution, the upper and lower walls of the exhaust plate are used to sweep the surface of the cooling plate, which can remove the dust adhering to the cooling plate and avoid the accumulation of dust during long-term use, which would reduce the cooling plate's ability and affect cooling. The exhaust plate transports airflow and blows the swept dust outward.

[0029] The beneficial effects of this invention are as follows:

[0030] 1. In this invention, the coolant is concentrated in a central shell and dispersed in a cooling shell. The pump body cools the coolant flowing into the cooling shell and then transports it through the second connecting channel to the central shell for centralized dispersion. After being diverted from the first conveying channel, the central shell transports the coolant to the cooling chamber through the first connecting channel connected to the corresponding cooling chamber. Then, the liquid moves from the cooling chamber to the input channel and into the cooling shell, where it is cooled. This cycle continues to cool the liquid.

[0031] 2. In this invention, the liquid moves into the annular shell, causing the traction plate to rotate. When the traction plate rotates, it drives the rotating shaft to rotate, which in turn drives the fan and gear one to rotate. The fan rotation pulls the airflow, which can accelerate the displacement of the airflow and help cool down. The rotation of gear one drives the rotation of gear two, which in turn drives the rotation of the reciprocating screw, causing the moving block to move on the reciprocating screw, and causing the outer cylinder and exhaust plate to move. In this way, as the exhaust plate moves, it drives the flow of external airflow. The airflow generated when the fan rotates will be discharged through the exhaust cavity of the exhaust plate. The cooling plate contacts the exhaust plate, and when the exhaust plate moves, it can sweep off the dust on the cooling plate. Then, the exhaust cavity blows air, which can blow away the swept dust. At the same time, the movement of the airflow can assist in cooling and accelerate the movement of the airflow.

The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0042] Reference Figures 1-6 This invention provides a compact busbar trunking system, comprising:

[0043] The outer casing 1 has several cooling plates 2 installed on both sides of the outer casing 1. The cooling plates 2 are used to assist in cooling the outer casing 1.

[0044] An active cooling component is installed on the left and right side walls and the top of the outer casing 1. The active cooling component includes an active cooling unit and a circulation pipe unit. The active cooling unit is installed on the top of the outer casing 1 and is connected to the circulation pipe units located on both sides of the outer casing 1.

[0045] The transmission processing assembly is installed on both sides of the housing 1. The transmission processing assembly includes a transmission unit and a movable processing unit. Several transmission units are evenly installed on both sides of the housing 1 and are connected to the circulation pipeline unit. Several movable processing units are installed and connected to the corresponding transmission units.

[0046] Several cooling plates 2 located on the same side are divided into two groups and distributed vertically. There is space between the two groups of cooling plates 2. The transmission unit and the active processing unit are installed between the two groups of cooling plates 2. The cooling plates 2 are used to assist in cooling the interior of the outer shell 1. The space between the cooling plates 2 facilitates the installation and operation of the other transmission units and active processing units.

[0047] The active cooling unit includes a central housing 3 installed on the top of the outer casing 1. One side of the central housing 3 is connected to a second connection channel 10, and the other end of the second connection channel 10 is connected to a pump body 9. The pump body 9 is connected to the inside of a cooling housing 8. A semiconductor cooler is installed in the cooling housing 8. The central housing 3 is used to concentrate and disperse the coolant. The pump body 9 cools the coolant flowing into the cooling housing 8 and then delivers it to the central housing 3 for centralized dispersion through the second connection channel 10.

[0048] The circulating pipeline unit includes a conveying channel 4 connected to both sides of the central shell 3. Several connecting channels 5 are installed on the side of the conveying channel 4 near the shell 1. Several vertically distributed cooling cavities 6 are opened on both sides of the shell 1. Both sides of the cooling shell 8 are connected to the input channel 7. Several branch pipes 2 are installed on the side of the input channel 7 near the shell 1. The connecting channels 5 are connected to one end of the corresponding cooling cavity 6, and the branch pipes 2 are connected to the other end of the corresponding cooling cavity 6.

[0049] The cooling chamber 6, located on a horizontal plane, is divided into two sections and connected by a transmission unit. The coolant can be circulated using a circulation pipe unit. After being diverted from the delivery channel 4 through the central shell 3, the coolant is transported to the cooling chamber 6 through the connecting channel 5 connected to the corresponding cooling chamber 6. After the liquid flows to the transmission unit, it triggers the movement of the transmission unit. Then, the liquid is transported from the cooling chamber 6 to the input channel 7 and moves into the cooling shell 8. The cooling shell 8 cools the liquid, and this cycle continues.

[0050] The transmission unit includes several annular shells 11 mounted on the side wall of the outer casing 1. Arc-shaped channels 12 are installed on both the front and rear sides of the annular shells 11. A rotating shaft 13 is rotatably connected to the annular shells 11. Several annularly spaced traction plates 14 are mounted on one end of the rotating shaft 13. A fan 19 is fixedly connected to one end of the rotating shaft 13 protruding from the annular shell 11. One end of a connecting rod 17 is fixedly connected to the outer wall of the annular shell 11. A fixed cylinder 16 is fixedly connected to the other end of the connecting rod 17. Several annularly spaced air inlets 27 are opened on the rear side of the fixed cylinder 16. When the liquid moves through the cooling chamber 6, it generates a traction force. When the liquid moves into the annular shells 11, it flows in the annular shells 11, thereby driving the rotation of the traction plates 14. When the traction plates 14 rotate, they drive the rotation of the rotating shaft 13, which in turn drives the rotation of the fan 19 and the gear 15. The rotation of the fan 19 will drive the movement of the airflow, thereby accelerating the displacement of the airflow and helping to cool down.

[0051] One end of the arc-shaped channel 12 is connected to the annular shell 11, and the other end of the arc-shaped channel 12 is connected to the corresponding cooling cavity 6. The cooling cavity 6 is installed between two adjacent cooling plates 2. The arc-shaped channel 12 and the annular shell 11 are used to connect the two cooling cavities 6 to form a loop, which can generate power. The cooling cavity 6 is installed between two adjacent cooling plates 2, which can cool the outer shell 1 and perform heat exchange.

[0052] The active processing unit includes several reciprocating screws 24 rotatably connected to the side wall of the outer casing 1 and a gear 15 mounted on the outside of the rotating shaft 13. A moving block 25 is threaded onto the reciprocating screw 24, and an outer cylinder 18 is fixedly connected to the top of the moving block 25. The outer cylinder 18 is sleeved on the outside of the fixed cylinder 16. Exhaust plates 20 are fixedly connected to both sides of the outer cylinder 18. An exhaust channel 21 is opened inside the exhaust plate 20, and two exhaust ports 22 are distributed vertically on the side wall of the exhaust plate 20 away from the outer casing 1. A fixing bracket 23 is installed on the side wall of the outer casing 1. A gear 26 is installed on the reciprocating screw 24. Rotation of the gear 15 drives the transmission... The rotating gear 26 drives the reciprocating screw 24, which in turn drives the moving block 25 to move on the reciprocating screw 24. The moving block 25 drives the outer cylinder 18 to move back and forth, and the outer cylinder 18 drives the connected exhaust plate 20 to move. As the exhaust plate 20 moves, the airflow generated by the fan 19 will be discharged through the exhaust chamber 21 of the exhaust plate 20. The cooling plate 2 contacts the exhaust plate 20. When the exhaust plate 20 moves, it can sweep off the dust on the cooling plate 2. Then the exhaust chamber 21 will blow air to blow away the swept dust. At the same time, the movement of the airflow can assist in cooling and accelerate the movement of the airflow.

[0053] The end of the reciprocating screw 24 away from the outer casing 1 is rotatably connected to the fixed frame 23. The inner wall of the outer cylinder 18 is slidably connected to the outer wall of the fixed cylinder 16 and sealed. The fixed frame 23 is used to support the reciprocating screw 24, making the rotation of the reciprocating screw 24 more stable. The outer cylinder 18 can move on the fixed cylinder 16, thereby driving the movement of the exhaust plate 20.

[0054] Several gears 15 and several gears 26 are connected by the same toothed belt. The exhaust plate 20 is located between two vertically adjacent cooling plates 2. Several gears 15 are connected by the same toothed belt. In this way, when the liquid drives the traction plate 14 to rotate through the annular shell 11, the traction force is concentrated on the toothed belt. This ensures uniform rotation and concentrated force.

[0055] The upper and lower side walls of the exhaust plate 20 are in contact with the outer wall of the corresponding cooling plate 2. The end of the exhaust plate 20 connected to the outer cylinder 18 is through-hole, and the end of the exhaust plate 20 away from the outer cylinder 18 is sealed. The upper and lower side walls of the exhaust plate 20 are used to sweep the surface of the cooling plate 2, which can remove the dust adhering to the cooling plate 2 and prevent the accumulation of dust during long-term use, which would reduce the cooling capacity of the cooling plate 2 and affect the cooling effect. The exhaust plate 20 transports airflow to blow the swept dust outward.

[0056] The specific implementation method is as follows: During use, when cooling, the centralized shell 3 is used to concentrate the coolant and disperse the coolant. The pump body 9 cools the coolant flowing into the cooling shell 8 and then delivers it to the centralized shell 3 for centralized dispersion through the connecting channel 10. After being diverted from the conveying channel 4, the centralized shell 3 delivers the coolant to the cooling chamber 6 through the connecting channel 5 connected to the corresponding cooling chamber 6. Then, the liquid moves from the cooling chamber 6 to the input channel 7 and into the cooling shell 8. The cooling shell 8 cools the liquid. This cycle continues to perform cooling.

[0057] As the liquid moves through the cooling chamber 6, it generates a traction force. When the liquid moves into the annular shell 11, it flows within the annular shell 11, thereby driving the rotation of the traction plate 14. The rotation of the traction plate 14 drives the rotation of the rotating shaft 13, which in turn drives the rotation of the fan 19 and gear 15. The rotation of the fan 19 pulls the airflow, accelerating its displacement and aiding in cooling. The rotation of gear 15 drives the rotation of the transmission-connected gear 26, which in turn drives the rotation of the reciprocating screw 24, thereby driving the movement of the fan 19 and gear 15. The moving block 25 moves on the reciprocating screw 24, and the moving block 25 drives the outer cylinder 18 to move back and forth. The outer cylinder 18 drives the connected exhaust plate 20 to move. In this way, while the exhaust plate 20 moves, the airflow generated by the fan 19 will be discharged through the exhaust chamber 21 of the exhaust plate 20. The cooling plate 2 contacts the exhaust plate 20. When the exhaust plate 20 moves, it can sweep off the dust on the cooling plate 2. Then the exhaust chamber 21 will blow air to blow away the swept dust. At the same time, the movement of the airflow can assist in cooling and accelerate the movement of the airflow.
