Description

Technical Field

[0001] The invention relates to the field of bus ducts, and in particular to an air-cooled bus duct with a multiple protection structure. Background Art

[0002] With the emergence of modern engineering facilities and equipment, the electricity consumption of all walks of life has increased rapidly, especially with the emergence of numerous high-rise buildings and large workshops. Traditional cables as transmission conductors can no longer meet the requirements in high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and construction connections. Plug-in bus ducts have emerged as a new type of distribution conductor. Compared with traditional cables, they fully demonstrate their superiority in high-current transmission, with the characteristics of small size, low energy consumption, easy maintenance, and long life. Bus ducts can be divided into three types according to the insulation method: air-type plug-in bus ducts, densely insulated plug-in bus ducts, and high-strength plug-in bus ducts. Air-cooled bus ducts are bus ducts that use air to cool and insulate the conductor.

[0003] The heat dissipation of existing air-type bus ducts mainly relies on convection between the air inside the duct and the air outside, and the heat dissipation efficiency is low. In addition, since the internal space of the bus duct is fixed, only a fixed number of conductors can be installed at one time. If the number of conductors needs to be increased or decreased according to the electrical equipment in the future, the entire bus duct needs to be replaced, resulting in a waste of resources.

[0004] Therefore, it is necessary to propose an air-cooled bus duct with multiple protection structures to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide an air-cooled bus duct with a multiple protection structure to solve the problem that the heat dissipation of the existing air-type bus duct mainly relies on the convection between the air in the duct body and the air outside, and the heat dissipation efficiency is low. Moreover, since the bus duct generally has a certain length, the outside air can only enter from both ends of the duct body, resulting in low heat exchange efficiency.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an air-cooled bus duct with a multiple protection structure, comprising a first trough body and a second trough body, wherein the first trough body and the second trough body each comprise two parallel side baffles, and at least two fixing mechanisms are installed between the two side baffles, the two fixing mechanisms are distributed in parallel along the length direction of the side baffles, the top and bottom ends of the two side baffles are both slidably fitted with sliding cover plates, and a temperature sensor and a humidity sensor are fixed on one side of the side baffle close to the fixing mechanism.

[0016] Preferably, a U-shaped plate is provided at the top end of the cooling fan, and the bottom end of the U-shaped plate is fixed to the top end of the corresponding sliding cover plate.

[0017] Technical effects and advantages of the present invention: 1. In the actual operation of the present invention, the number of docking blocks can be increased according to the number of conductors in actual conditions. When electrical equipment is added later and conductors need to be added, the number of docking blocks can be increased between the first connecting block and the second connecting block to support and fix the excess conductors, thereby avoiding direct replacement of the entire bus duct. When the number of conductors needs to be reduced, the excess docking blocks and conductors can be directly removed, and the installed first connecting block, the second connecting block and the docking block can be reinforced and fixed by the cooperation of the first nut and the threaded column.

[0018] 2. The two docking blocks can also be docked and installed through their respective slots and blocks. When the first connection block, multiple docking blocks and the second connection block are docked and installed in parallel, when the first connection block and the second connection block press the conductor downward, the docking block will also follow and press the conductor downward.

[0019] 3. Furthermore, when the first connecting block is installed between the docking block or multiple docking blocks are installed, the card block can slide inside the corresponding slide groove to change the protruding length of the card block in the slide groove. When the protruding length of the card block is longer, the installation length between the first connecting block and the docking block or multiple docking blocks will be longer. At this time, the gap between the two conductors will also become larger, so that the air flow channel between the two conductors will become wider, thereby improving the heat dissipation effect. At the same time, the increase in air between the two conductors will also improve the insulation of the air.

[0020] 4. In the actual operation of the present invention, when the temperature sensor detects that the temperature between the two side baffles is high or the humidity is high, the cooling fan can be controlled to start, and wind can be generated to enter the cavity in the first connecting block through the air pipe. Since the first connecting block, the docking block and the second connecting block are in a connected state, air can enter the cavities inside the docking block and the second connecting block respectively, and part of the wind in the cavity is discharged from the heat dissipation hole. The wind can dissipate the heat at the connection between the conductor and the socket, avoid heat accumulation at the connection between the top of the conductor and the socket, and improve the heat dissipation effect. At the same time, the generated wind passes through the gap between the two conductors, accelerates the air circulation speed, and improves the heat dissipation efficiency.

[0021] 5. At the same time, another part of the wind force in the cavity can be discharged from the air groove at the bottom of the card seat. The wind force discharged from the air groove can drop to the inside of another card seat corresponding vertically, and the wind force entering the inside of another card seat can be discharged from the corresponding heat dissipation holes to dissipate the heat at the connection between the bottom end of the conductor and the corresponding card seat, which plays the role of dissipating the heat at the connection between the upper and lower ends of the conductor at the same time, so that the heat is discharged more evenly.

[0022] 6. Due to the large number of fixed clamps, water vapor is easily accumulated. The effect of wind can make the air molecules between the upper and lower corresponding holders in a more active state of motion. When the air is relatively humid, it can speed up the dispersion of molecules and prevent water vapor from gathering together, which can enhance the insulation of the air and reduce the possibility of conductivity. At the same time, the effect of wind can blow out the dust between the two side baffles to reduce dust accumulation.

[0023] 7. When the cooling fan generates wind and blows downward through the top seat, the wind discharged from the air groove will push the rotating plate in the bottom sliding cover to rotate downward, and one end of the rotating plate will pop out the sliding cover. At this time, the opening is in an open state, so that the inside of the first slot body is connected with the outside, so that excess heat and wind can be directly discharged to the outside, and the outside air and the internal air can be exchanged, thereby improving the heat dissipation efficiency and reducing the heat movement path.

[0024] 8. In the actual operation of the present invention, when there is one or two second trough bodies, the second trough body and the first trough body can be connected by installing the docking pipe of the second trough body and the connecting pipe of the first trough body, thereby improving the stability between the second trough body and the first trough body after installation and improving the structural strength. At the same time, temperature sensors are provided inside the second trough body and the first trough body. When the temperature inside a second trough body is high, the solenoid valve can be opened to allow the wind force generated by the cooling fan to enter the second trough body corresponding to the increased temperature to dissipate the heat of the conductor. Only one cooling fan can dissipate heat for multiple bus ducts at the same time, or dissipate heat for a single bus duct.

[0025] 9. Furthermore, when wind passes through the butt-joint pipe, since the radius inside the butt-joint pipe is smaller than the radius inside the connecting pipe, the wind moves from the end with a larger aperture to the end with a smaller aperture, which can reduce the temperature of the wind. When multiple bus ducts are cooled at the same time, the purpose of improving the heat dissipation efficiency is achieved by reducing the temperature of the wind. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clarify the technical solutions in the embodiments of the present invention; it is clearly described in detail. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The present invention provides Figure 1 - Figure 8 An air-cooled bus duct with a multiple protection structure shown in the figure comprises a first trough body 33 and a second trough body 39, each of which comprises two side baffles 1 arranged in parallel, and at least two fixing mechanisms 5 are installed between the two side baffles 1, and the two fixing mechanisms 5 are distributed in parallel along the length direction of the side baffles 1, and the top and bottom ends of the two side baffles 1 are slidably fitted with sliding cover plates 2; The fixing mechanism 5 includes two fixing clamps 20, which are arranged opposite to each other in the vertical direction. The conductor 6 is clamped between the two fixing clamps 20. A space is formed between the two side baffles 1 and the two sliding cover plates 2 to protect the clamped conductor 6 inside and prevent external dust and collision from affecting the conductor 6.

[0037] The top and bottom ends of the two side baffles 1 on the side away from each other are fixed with L-shaped protrusions 7, and the sides of the two transversely parallel L-shaped protrusions 7 on the sides away from each other are provided with sliding grooves 12. The sliding cover 2 is set to be U-shaped, and sliders 11 are fixed on both sides inside the U-shaped structure. The sliders 11 slide and fit in the corresponding sliding grooves 12. After the two side baffles 1 and the fixing mechanism 5 are installed, the sliding cover 2 can be slidably installed in the sliding grooves 12 of the side baffles 1. It is convenient to install and disassemble, saving installation and disassembly time, and will not cause problems such as thread slippage and jamming like bolt fixing.

[0038] The fixing clamp 20 includes a first connecting block 13, a docking block 17 and a second connecting block 18, which are installed in parallel and plugged in sequence. The first connecting block 13 and the second connecting block 18 are fixed with threaded columns 9 on the sides away from each other, and the two side baffles 1 are provided with through grooves 8 for the corresponding threaded columns 9 to pass through on the sides away from each other. The outer threads of the threaded columns 9 are matched with the first nut 10, and one side of the first nut 10 is pressed tightly against the surface of the corresponding side baffle 1.

[0039] In the actual operation of the present invention, the first connection block 13, the docking block 17 and the second connection block 18 can be installed in parallel in sequence to form a complete fixing clamp block 20, and the two vertically opposite fixing clamp blocks 20 can clamp and fix the upper and lower ends of the conductor 6.

[0040] At the same time, the threaded column 9 on the side where the first connecting block 13 and the second connecting block 18 are away from each other can pass through the through groove 8 on the side baffle 1, and the side baffle 1 and the corresponding first connecting block 13 or second connecting block 18 can be fixed by the first nut 10, thereby completing the fixed installation of the side baffle 1 and the fixing clamp 20.

[0041] Specifically, the surfaces of the first connecting block 13, the docking block 17 and the second connecting block 18 are all fixed with a socket 15, the conductors 6 are engaged in the sockets 15 which correspond to each other vertically, and connecting rods 19 are slidably installed between the two first connecting blocks 13 and between the two second connecting blocks 18, and the two ends of the outer side of the connecting rod 19 are threadedly fitted with a second nut 22.

[0042] In addition, the two vertically corresponding first connecting blocks 13 and second connecting blocks 18 can be supported by a connecting rod 19. By tightening the second nut 22, the two vertically corresponding first connecting blocks 13 and second connecting blocks 18 can be brought close to each other, which is convenient for pressing the upper and lower ends of the conductor 6. Since through grooves 8 are provided on both sides of the side baffle 1, when the first connecting block 13 and the second connecting block 18 move up and down, the corresponding threaded column 9 can follow and move up and down in the through groove 8, which is convenient for matching positions and avoids affecting the rising movement of the first connecting block 13 and the second connecting block 18.

[0043] During the use of the bus duct, due to the addition of external equipment, the number of busbars required will also increase accordingly. Usually, the busbars are added by adding new bus ducts, but it is time-consuming and labor-intensive. Therefore, a slide groove 34 is provided on the side of the first connecting block 13 and the docking block 17 close to the second connecting block 18, and a card block 31 is slidably matched inside the slide groove 34. A card groove 21 is provided on the side of the docking block 17 and the second connecting block 18 close to the first connecting block 13. The card block 31 is inserted into the corresponding card groove 21. A groove for the end of the conductor 6 to extend into is provided in the card seat 15. Arc blocks 16 are fixed on both sides of the groove. The arc surfaces of the two arc blocks 16 are respectively attached to the two sides of the conductor 6, and the arc blocks 16 are elastic. The two arc blocks 16 can squeeze the two sides of the conductor 6 to prevent the conductor 6 from shaking left and right. At least one docking block 17 is provided.

[0044] In the actual operation of the present invention, the number of docking blocks 17 can be increased according to the number of conductors 6 in actual conditions. When the electrical equipment is added later and the conductors 6 need to be added, the number of docking blocks 17 can be increased between the first connecting block 13 and the second connecting block 18 to support and fix the excess conductors 6, avoiding the direct replacement of the entire bus duct. When the number of conductors 6 needs to be reduced, the excess docking blocks 17 and conductors 6 can be directly removed, and the installed first connecting block 13, the second connecting block 18 and the docking block 17 can be strengthened and fixed by the cooperation of the first nut 10 and the threaded column 9, and only the sliding cover plate 2 of different widths needs to be replaced.

[0045] Moreover, the docking blocks 17 can be docked and installed in pairs through their respective slots 21 and blocks 31. After the first connection block 13, multiple docking blocks 17 and the second connection block 18 are docked and installed in parallel, when the first connection block 13 and the second connection block 18 press the conductor 6 downward, the docking block 17 will also follow and press the conductor 6 downward. Since the docking blocks 17 can be increased or decreased as needed, it is also convenient to increase or decrease the number of conductors 6 at a later stage, which is convenient for personnel to carry out maintenance.

[0046] At the same time, the first connecting block 13, the multiple docking blocks 17 and the socket 15 at the bottom of the second connecting block 18 can not only fix the conductor 6, but also create gaps between the conductors 6 to facilitate air circulation between the conductors 6, facilitate convection between the air in the slot and the outside air, and at the same time insulate the conductors 6 through the air.

[0047] Furthermore, when the first connecting block 13 is installed between the docking block 17 or multiple docking blocks 17 are installed, the card block 31 can slide inside the corresponding slide groove 34 to change the protruding length of the card block 31 in the slide groove 34. When the protruding length of the card block 31 is longer, the installation length between the first connecting block 13 and the docking block 17 or multiple docking blocks 17 will be longer. At this time, the gap between the conductors 6 will also become larger, so that the air flow channel between the conductors 6 will become wider, thereby improving the heat dissipation effect. At the same time, the increase in air between the conductors 6 will also improve the insulation of the air.

[0048] A cooling fan 4 is fixed on the top of one of the sliding cover plates 2 arranged at the top, a temperature sensor and a humidity sensor are fixed on one side of one of the side baffles 1 close to the fixing mechanism 5, cavities are provided inside the first connecting block 13, a through hole 35 is provided on one side of the card block 31, and the through hole 35 runs through the other side of the card block 31, the top of the first connecting block 13 is connected to the air pipe 14, the bottom end of the air pipe 14 is connected to the cavity of the first connecting block 13, the air outlet at the bottom end of the cooling fan 4 is connected to the top of the air pipe 14, and the through hole 35 is connected to the corresponding cavity, a heat dissipation hole 30 is provided at the top of the groove, the air hole 14 and the heat dissipation hole 30 are connected to the corresponding cavity, the top of the first connecting block 13 and the docking block 17 are provided with a second fixing screw, and the bottom end of the second fixing screw is pressed tightly against the top of the corresponding card block 31.

[0049] Air grooves 23 are provided at both ends of the opposite sides of the two vertically corresponding card seats 15 , and the two air grooves 23 are connected to the corresponding cavities.

[0050] In the actual operation of the present invention, when the temperature sensor detects that the temperature between the two side baffles 1 is high or the humidity is high, the cooling fan 4 can be controlled to start, and wind can be generated to enter the cavity in the first connecting block 13 through the air pipe. Since the first connecting block 13, the docking block 17 and the second connecting block 18 are in a connected state, air can enter the cavities inside the docking block 17 and the second connecting block 18 respectively, and a part of the wind in the cavity is discharged from the heat dissipation hole 30. The wind can dissipate the heat at the connection between the conductor 6 and the socket 15, avoid heat accumulation at the connection between the top of the conductor 6 and the socket 15, and improve the heat dissipation effect. At the same time, the generated wind passes through the gap between the two conductors 6, accelerates the air circulation speed, and improves the heat dissipation efficiency.

[0051] At the same time, another part of the wind force in the cavity can be discharged from the air groove 23 at the bottom end of the holder 15. The wind force discharged from the air groove 23 can drop to the inside of another vertically corresponding holder 15, and the wind force entering the inside of another holder 15 can be discharged from the corresponding heat dissipation hole 30, so as to dissipate the heat at the connection between the bottom end of the conductor 6 and the corresponding holder 15, thereby dissipating the heat at the upper and lower ends of the conductor 6 at the same time, so that the heat can be discharged more evenly.

[0052] Since the fixed clamp block 20 has many structures and is prone to accumulate water vapor, the effect of wind can make the air molecules between the upper and lower corresponding holders 15 be in a more active state of motion. When the air is relatively humid, the dispersion of molecules can be accelerated to prevent water vapor from gathering together, which can enhance the insulation of the air and reduce the possibility of conductivity. At the same time, the effect of wind can blow out the dust between the two side baffles 1 to reduce dust accumulation.

[0053] Since the side baffle 1 is generally long, the internal air and heat can only be discharged from the two ends of the groove body, and the heat dissipation efficiency is low. Therefore, a plurality of through openings 32 are opened at the bottom end of one of the sliding cover plates 2 arranged at the bottom end of the side baffle 1, and a rotating plate 24 is rotatably installed inside the plurality of through openings 32. One end of the rotating plate 24 is rotatably connected to one side of the inside of the through opening 32, and an elastic rope 25 is connected between the top of the other end of the rotating plate 24 and the inside of the through opening 32.

[0054] Furthermore, when the cooling fan 4 generates wind that blows downward through the top seat 15, the wind discharged from the air groove 23 will push the rotating plate 24 in the bottom sliding cover 2 to rotate downward, and one end of the rotating plate 24 will pop out of the sliding cover 2. At this time, the through hole 32 is in an open state, so that the interior of the first groove body 33 is connected with the outside, so that excess heat and wind can be directly discharged to the outside, and the outside air and the internal air can be exchanged, thereby improving the heat dissipation efficiency and reducing the heat movement path.

[0055] When the cooling fan 4 stops, the rotating plate 24 is pulled by the elastic rope 25 and can automatically rotate and close the opening 32 to prevent external dust and impurities from entering the two first slots 33 and affecting the conductor 6.

[0056] A support and protection mechanism is installed between the two L-shaped protruding ends 7, and the support and protection mechanism includes an L-shaped block 26 and an L-shaped protruding block 28. The bottom ends of the L-shaped block 26 and the L-shaped protruding block 28 are respectively installed in the corresponding L-shaped protruding ends 7, and an extension block 27 is fixed on the side of the L-shaped block 26 close to the L-shaped protruding block 28. The side of the L-shaped protruding block 28 close to the L-shaped block 26 is provided with an embedded groove for the extension block 27 to extend into. The top of the L-shaped protruding block 28 is provided with a first fixing screw 29, and the bottom end of the first fixing screw 29 is pressed against the surface of the extension block 27. The support and protection mechanism can increase the support strength between the two side baffles 1 and increase the protection effect on the conductor 6. When impacted by the outside, the impact resistance of the side baffle 1 can be increased. At the same time, the outer side of the conductor 6 is coated with a high-voltage resistant insulating layer medium to improve the insulation and protection effect, and play a multi-protection effect.

[0057] At the same time, the length between the L-shaped block 26 and the L-shaped protruding block 28 can be adjusted, and the extension block 27 can be pulled out or pushed in from the embedded groove to change the length between the L-shaped block 26 and the L-shaped protruding block 28. When the length is determined, the position of the extension block 27 can be fixed by the first fixing screw 29 to facilitate the installation of different numbers of docking blocks 17.

[0058] At least one second tank body 39 is provided, connecting pipes 37 are provided on both sides of the first tank body 33, and a docking pipe 36 is connected to the side of the second tank body 39 close to the first tank body 33, the docking pipe 36 and the connecting pipe 37 are connected, and solenoid valves 38 are provided at the connection between the two sides of the first tank body 33 and the connecting pipe 37, the connecting pipe 37 and the cooling fan 4 are connected, temperature sensors are fixed inside the first tank body 33 and the second tank body 39, the radius inside the docking pipe 36 is smaller than the radius inside the connecting pipe 37, and the air pipe 14 inside the second tank body 39 is connected to the docking pipe 36.

[0059] At the same time, the supporting and protecting mechanism can slide on the two L-shaped protruding ends 7, so that the supporting and protecting mechanism can be moved to a suitable position for support, for example, installed at a position where the side baffle 1 is easily hit.

[0060] The two side baffles 1 and the sliding cover 2 are both made of aluminum-magnesium alloy (6063-T5), which has a hard texture, good heat dissipation performance and is easy to assemble.

[0061] A U-shaped plate 3 is provided at the top of the cooling fan 4, and the bottom end of the U-shaped plate 3 is fixed to the top of the corresponding sliding cover plate 2. The U-shaped opening of the U-shaped plate 3 faces downward, which can protect the top of the cooling fan 4 and prevent dust in the air from falling into the interior of the cooling fan 4. A filter is provided at the space connecting the air outlet of the cooling fan 4 and the two side baffles 1 to intercept dust.
