Description

Technical Field

[0001] The present invention belongs to the technical field of bus ducts, and particularly relates to a compact bus duct with a heat dissipation component. Background Art

[0002] A bus duct is a common power structure, which is mainly a closed metal device composed of copper and aluminum bus bars, and its main function is to distribute relatively large power to each component of a decentralized system. In indoor low-voltage power transmission main line engineering projects, it has increasingly replaced wire and cable, and has strong electrical conductivity.

[0003] Chinese Patent CN107800091A discloses a bus duct. The bus duct includes: a housing, an insulating material, and a copper bar. The insulating material and the copper bar are fixed on the inner wall of the housing, and the insulating material separates the housing from the copper bar. A guiding device is also provided on the side of the copper bar inside the bus duct. It is used to replace wire and cable for power transmission and distribution in a power supply system, and can also be used for power transmission and distribution of server cabinets in a data center. The bus duct includes a housing, an insulating material, and a copper bar. The insulating material and the copper bar are fixed on the inner wall of the housing, and the insulating material separates the housing from the copper bar. A guiding device is also provided on the side of the copper bar inside the bus duct. When installing a feed-out device, the guiding device can guide the power-taking contact into the correct position, ensuring good contact between the contact and the copper bar inside the bus duct and the safety of power use. However, some current bus ducts, due to their separate housing structures and the lack of some power supply driving mechanisms on them, cannot guarantee the heat dissipation effect of the bus duct itself. Often, after a long time of use, heat accumulation and overheating on the bus duct are likely to occur. In the long run, it will have a certain adverse impact on the lifespan of the bus duct itself. At the same time, long-term high temperature also poses some fire hazards, and the safety cannot be guaranteed. Also, since the bus duct is generally installed at a high place, after a long time of use, a large amount of dust is likely to accumulate on the bottom surface in contact with the air below it, affecting the working effect of the bus duct. Moreover, it is not easy to clean at a high place, and a climbing ladder is needed for cleaning, and high-altitude operation is somewhat dangerous. In order to effectively solve the above problems, there is an urgent need for a compact bus duct with a heat dissipation component. Summary of the Invention

[0004] The object of the present invention is to solve the problems that some existing busbars are separate shell structures and do not have power supply driving mechanisms, resulting in the inability to guarantee the heat dissipation effect of the busbars themselves. After long-term use, heat accumulation and overheating often occur on the busbars, which will have a certain adverse impact on the lifespan of the busbars themselves in the long run. At the same time, long-term high temperatures also pose some fire hazards and the safety cannot be guaranteed. In addition, since busbars are generally installed at high places, after long-term use, a large amount of dust is likely to accumulate on the bottom surface in contact with the air below, affecting the working effect of the busbars. Moreover, it is not easy to clean them at high places and a climbing ladder is needed for cleaning, and working at high places is somewhat dangerous. Therefore, a dense busbar with a heat dissipation component is proposed.

[0005] To achieve the above object, the present invention adopts the following technical solution: A dense busbar with a heat dissipation component, including a housing. Busbar end pieces and protective side plates are fixedly installed at both ends of the housing. An installation top groove is provided on the top surface of the housing. A number of heat dissipation holes are provided on the top surface of the installation top groove. A bottom groove is provided inside the installation top groove. Guide rails are fixedly installed on the inner wall of the installation top groove. A cleaning component is arranged on the guide rails, and the cleaning component is used for the conduction and dissipation of the heat of the busbar. An automatic winding component is rotatably installed on the inner wall of the bottom groove, and the automatic winding component is used for driving the cleaning component. A dust cleaning and heat dissipation component is arranged on the top surface of the installation top groove on one side of the cleaning component, and the dust cleaning and heat dissipation component is used for the dissipation of the hot air flow around the busbar.

[0006] As a further description of the above technical solution:

[0007] The cleaning component includes a mounting plate, which is fixedly installed on the top surface of the installation top groove. Two connecting springs are fixedly installed on the outer wall of one side of the mounting plate. One end of the two connecting springs is fixedly installed with a mounting brush seat. The mounting brush seat is slidably connected to the guide rail through a chute provided on its outside. One end of the mounting brush seat is fixedly installed with a cleaning side brush, and the cleaning side brush is in close contact with the top surface of the installation top groove.

[0008] As a further description of the above technical solution:

[0009] The automatic winding component includes a connecting shaft, which is rotatably installed on the inner wall of the bottom groove. A torsion spring and a storage roller shaft are fixedly installed on the outside of the connecting shaft. Two torsion springs are symmetrically installed about the longitudinal center plane of the storage roller shaft.

[0010] As a further description of the above technical solution:

[0011] One end of the torsion spring is fixedly connected to one inner wall of the bottom groove. An automatic winding belt is wound around the storage roller shaft. A plurality of pores are arranged inside the automatic winding belt. One end of the automatic winding belt is fixedly connected to one side wall of the installation brush base. A pulling component is rotatably installed on one outer wall of the housing. The pulling component is used for the stable drive of the automatic winding component. The pulling component includes a mounting shaft sleeve. The mounting shaft sleeve is fixedly installed on one outer wall of the housing. A disc shaft is rotatably installed inside the mounting shaft sleeve. One end of the disc shaft passes through the housing and is fixedly connected to one end of a connecting shaft. A winding disc is fixedly installed at the other end of the disc shaft. A pulling belt is wound around the outside of the winding disc. One end of the pulling belt is fixedly installed with a pull ring.

[0012] As a further description of the above technical solution:

[0013] The dust cleaning and heat dissipation component includes a threaded shaft and a cylinder frame. An installation bottom shaft is longitudinally and fixedly installed at the bottom of the threaded shaft. The bottom end of the installation bottom shaft is fixedly connected to the upper surface of the installation top groove. The cylinder frame is fixedly installed on the upper surface of the installation brush base. A threaded cylinder is rotatably installed inside the cylinder frame. A heat dissipation and dust cleaning fan is fixedly installed on the outside of the threaded cylinder. The threaded shaft and the threaded cylinder are in threaded connection.

[0014] When the hand releases the pulling belt, the stretched connecting spring will quickly retract, causing the installation brush seat to reset, thereby realizing the reciprocating motion of the cleaning component and performing reciprocating cleaning of the bus duct. The dust collecting fan is rotated by the threaded cylinder and the heat dissipation fan is rotated, and the rotation of the heat dissipation fan can generate airflow above the brush holder, which can effectively take away the heat emitted by the bus duct and ensure the heat dissipation effect of the bus duct. Secondly, it can assist in the installation of the brush holder and the cleaning side brush, and quickly blow off the dust cleaned by the cleaning side brush to improve the dust cleaning effect. Through this design, the bus duct can be quickly cleaned without the help of any climbing tools after the surface of the bus duct has been used for a period of time, thereby ensuring the overall safety of the cleaning operation and achieving a good and stable heat dissipation effect during the use of the bus duct. At the same time, it can complete the cleaning of the dust in the heat dissipation holes to ensure the heat dissipation effect and generate a certain amount of wind outside, which is conducive to taking away the heat discharged by the bus duct, and the application effect is good.

[0015] As a further description of the above technical solution:

[0016] A built-in groove is provided inside the shell, and two air inlet and heat dissipation components are provided inside the built-in groove. The air inlet and heat dissipation components are used to collect and increase the speed of the external ambient airflow. The air inlet and heat dissipation components include an air inlet tube, which is fixedly installed inside the built-in groove, and a guide groove is provided on the inner wall of the air inlet tube.

[0017] As a further description of the above technical solution:

[0018] A mounting shaft bracket is fixedly installed on the inner wall of the air inlet tube, a mounting shaft is rotatably installed inside the mounting shaft bracket, an inclined fan blade is fixedly installed outside the mounting shaft, and an air flow speed increasing volute is fixedly installed inside the air inlet tube on one side of the mounting shaft.

[0021] As a further description of the above technical solution:

[0022] The limiting sliding shaft is fixedly installed in the housing cavity of the housing. The clamping shaft is slidably installed inside the built-in shaft hole. A limiting travel groove is arranged on the outer wall of one side of the clamping shaft. One end of the limiting sliding shaft is slidably connected with the limiting travel groove. The bidirectional stud is threadedly installed inside the clamping shaft, and a driven meshing shaft is fixedly installed at the middle position of the bidirectional stud.

[0023] As a further description of the above technical solution:

[0024] A sliding shaft hole is arranged at the bottom of the housing, and a pressure-bearing meshing shaft is slidably installed inside the sliding shaft hole. One end of the pressure-bearing meshing shaft is located outside the housing, and the other end of the pressure-bearing meshing shaft is meshed and connected with the driven meshing shaft.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0026] When the pulling belt is released by the user's hand, the stretched connecting spring will retract quickly, causing the installed brush seat to reset, realizing the reciprocating motion of the cleaning assembly, and the bus duct is cleaned reciprocatingly. The dust collecting fan is rotated by the threaded barrel and the heat dissipation fan is rotated, and the rotation of the heat dissipation fan can generate airflow above the brush holder, which can effectively take away the heat emitted by the bus duct and ensure the heat dissipation effect of the bus duct. Secondly, it can assist in the installation of the brush holder and the cleaning side brush, and quickly blow off the dust cleaned by the cleaning side brush to improve the dust cleaning effect. Through this design, the bus duct can be quickly cleaned without the aid of any climbing tools after the surface of the bus duct has been used for a period of time, thereby ensuring the overall safety of the cleaning operation. At the same time, it can simultaneously achieve a good and stable heat dissipation effect for the bus duct during use, and at the same time complete the dust cleaning of the heat dissipation holes to ensure the heat dissipation effect, and can generate a certain amount of wind outside, which is conducive to taking away the heat discharged by the bus duct, and the application effect is good.

[0027] 2. In the present invention, an air inlet and heat dissipation component is provided. When the bus duct is normally used, the airflow in the external environment can enter the air inlet and heat dissipation component. Due to the oblique setting of the oblique fan blades, the airflow entering the air inlet and heat dissipation component can drive the oblique fan blades and the mounting shaft to rotate, so that the airflow can flow rapidly in the guide groove provided on the inner wall of the air inlet tube, and then be conducted to the airflow speed increasing volute. After the airflow enters the airflow speed increasing volute, due to the narrow air duct design in the airflow speed increasing volute, the incoming airflow flows rapidly to both sides and is then exported, thereby bringing out the heat in the bus duct through the heat dissipation holes. Through this design, the airflow in the external environment can be captured and accelerated. When used in conjunction with the cleaning component, the automatic winding component, and the dust cleaning and heat dissipation component, the heat dissipation effect of the bus duct can be further improved.

[0028] 3. In the present invention, with a clamping component and a pressure-bearing meshing shaft provided inside, when installing this busbar trunking, simply turn the busbar trunking over so that the housing is embedded in the installation structure. At this time, the pressure-bearing meshing shaft will move inward under pressure. Through the meshing action, the pressure-bearing meshing shaft can drive the bidirectional stud with a driven meshing shaft to rotate. Since there are reverse threads on the bidirectional stud, while the bidirectional stud rotates, the clamping shafts at both ends of the bidirectional stud can be simultaneously displaced outward, so that the clamping shafts automatically snap into the clamping holes on the side of the installation structure, completing the installation. Through this design, the rapid installation of this busbar trunking can be achieved. The installation is simple and convenient, and it can be completed without other installation parts and tools, with good use effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0043] Please refer to Figures 1-11 , the present invention provides a technical solution: a densified busbar trunking with a heat dissipation component, including a housing 2. Both ends of the housing 2 are fixedly installed with a busbar trunking end piece 1 and a protection side plate 8. The top surface of the housing 2 is provided with an installation top groove 6. The top surface of the installation top groove 6 is provided with a plurality of heat dissipation holes 12. The inside of the installation top groove 6 is provided with a bottom groove 13. The inner wall of the installation top groove 6 is fixedly installed with a guide rail 11. A cleaning component 4 is arranged on the guide rail 11. The cleaning component 4 is used for the conduction and dissipation of the heat of the busbar trunking. The inner wall of the bottom groove 13 is rotatably installed with an automatic winding component 10. The automatic winding component 10 is used for driving the cleaning component 4. A dust cleaning and heat dissipation component 3 is arranged on the top surface of the installation top groove 6 on one side of the cleaning component 4. The dust cleaning and heat dissipation component 3 is used for the dissipation of the hot air flow around the busbar trunking.

[0044] The cleaning component 4 includes a mounting plate 42 which is fixedly installed on the top surface of the mounting top groove 6. Two connecting springs 43 are fixedly installed on one outer wall of the mounting plate 42. One end of each of the two connecting springs 43 is fixedly installed with a mounting brush base 41. The mounting brush base 41 is made of copper. The mounting brush base 41 is slidably connected to the guide rail 11 through a chute provided on its outer side. One end of the mounting brush base 41 is fixedly installed with a cleaning side brush 44, and the cleaning side brush 44 is in close contact with the top surface of the mounting top groove 6.

[0045] The automatic winding component 10 includes a connecting shaft 104 which is rotatably installed on the inner wall of the bottom groove 13. A torsion spring 103 and a storage roller shaft 105 are fixedly installed on the outside of the connecting shaft 104. Two torsion springs 103 are symmetrically installed about the longitudinal center plane of the storage roller shaft 105. One end of the torsion spring 103 is fixedly connected to one inner wall of the bottom groove 13. An automatic winding belt 101 is wound around the storage roller shaft 105. A number of pores 102 are provided inside the automatic winding belt 101. One end of the automatic winding belt 101 is fixedly connected to one side wall of the mounting brush base 41. A pulling component 17 is rotatably installed on one outer wall of the housing 2. The pulling component 17 is used for the stable driving of the automatic winding component 10. The pulling component 17 includes a mounting shaft sleeve 175 which is fixedly installed on one outer wall of the housing 2. A disk shaft 174 is rotatably installed inside the mounting shaft sleeve 175. One end of the disk shaft 174 passes through the housing 2 and is fixedly connected to one end of the connecting shaft 104. A tape take-up reel 173 is fixedly installed at the other end of the disk shaft 174. A pulling belt 172 is wound around the outside of the tape take-up reel 173. One end of the pulling belt 172 is fixedly installed with a pull ring 171.

[0046] The dust cleaning and heat dissipation component 3 includes a threaded shaft 31 and a cylinder frame 34. A mounting bottom shaft 32 is longitudinally and fixedly installed at the bottom of the threaded shaft 31. The bottom end of the mounting bottom shaft 32 is fixedly connected to the upper surface of the mounting top groove 6. The cylinder frame 34 is fixedly installed on the upper surface of the mounting brush base 41. A threaded cylinder 35 is rotatably installed inside the cylinder frame 34. A heat dissipation and dust cleaning fan 33 is fixedly installed on the outside of the threaded cylinder 35. The threaded shaft 31 and the threaded cylinder 35 are in threaded connection.

[0047] The specific implementation method is as follows: after the bus duct has been installed and used for a period of time, when a certain amount of dust has accumulated on the lower surface of the bus duct, people can directly pull the pulling belt 172 through the pull ring 171 of the pulling assembly 17. As the pulling belt 172 is pulled down, the take-up reel 173 can rotate, and the reel shaft 174 will rotate synchronously. At this time, the reel shaft 174 can drive the receiving roller 105 with the connecting shaft 104 to rotate, and the receiving roller 105 can reel in the automatic reeling belt 101 thereon. At this time, the installation brush holder 41 can be pulled to move synchronously with the cleaning side brush 44. At this time, the connecting spring 43 is stretched. During the displacement process, the cleaning side brush 44 at one end of the installation brush holder 41 can synchronously wipe the surface of the heat dissipation hole, thereby achieving a good dust removal and cleaning treatment for the bus duct and preventing dust from clogging the heat dissipation hole. The heat hole ensures the heat dissipation effect. When the person releases the pulling belt 172, the stretched connecting spring 43 will retract quickly, causing the installation brush holder 41 to reset, realizing the reciprocating motion of the cleaning component 4, and performing reciprocating cleaning of the bus duct. At the same time, when the cleaning component 4 reciprocates, it can synchronously drive the barrel rack 34 and the threaded barrel 35 thereon to move back and forth. Since there is a threaded connection relationship between the threaded barrel 35 and the threaded shaft 31, the threaded barrel 35 can drive the heat dissipation and dust cleaning fan 33 to rotate during the displacement process. The rotation of the heat dissipation and dust cleaning fan 33 can generate airflow above the installation brush holder 41, which can effectively take away the heat emitted by the bus duct and ensure the heat dissipation effect of the bus duct. Secondly, it can assist the installation of the brush holder 41 and the cleaning side brush 44, and quickly blow off the dust cleaned by the cleaning side brush 44, thereby improving the dust cleaning effect.

[0048] Through this design, after the bus duct has been used for a period of time and dust has accumulated on its surface, the bus duct can be quickly cleaned without the help of any climbing tools, ensuring the overall safety of the cleaning operation. At the same time, a good and stable heat dissipation effect can be achieved during the use of the bus duct. At the same time, the dust in the heat dissipation holes can be cleaned to ensure the heat dissipation effect, and a certain amount of wind can be generated externally, which is conducive to taking away the heat discharged by the bus duct, and the application effect is good.

[0049] The shell 2 is provided with a built-in groove 15, and the built-in groove 15 is provided with two air inlet and heat dissipation components 7. The air inlet and heat dissipation components 7 are used to collect and increase the speed of the external ambient airflow. The air inlet and heat dissipation components 7 include an air inlet tube 72, and the air inlet tube 72 is fixedly installed inside the built-in groove 15. A guide groove 71 is provided on the inner wall of the air inlet tube 72. A mounting shaft frame 74 is fixedly installed on the inner wall of the air inlet tube 72. A mounting shaft 73 is rotatably installed inside the mounting shaft frame 74. An inclined fan blade 75 is fixedly installed on the outside of the mounting shaft 73. An airflow increasing volute 76 is fixedly installed on one side of the mounting shaft 73 inside the air inlet tube 72.

[0050] The specific implementation method is as follows: When the busbar trunking is in normal use, the air flow in the external environment can enter the air intake and heat dissipation component 7. Due to the oblique setting of the oblique blades 75, the air flow entering the air intake and heat dissipation component 7 can drive the oblique blades 75 and the mounting shaft 73 to rotate, enabling the air flow to flow rapidly on the diversion grooves 71 provided on the inner wall of the air intake cylinder 72, and then conducting to the air flow acceleration volute 76. After the air flow enters the air flow acceleration volute 76, due to the narrow air duct design in the air flow acceleration volute 76, the entering air flow rapidly flows to both sides and is then led out, thereby taking out the heat in the busbar trunking through the heat dissipation holes 12.

[0051] Through this structural design, it is possible to capture and accelerate the air flow in the external environment. When used in conjunction with the cleaning component 4, the automatic winding component 10, and the dust cleaning and heat dissipation component 3, the heat dissipation effect of the busbar trunking can be further improved.

[0052] An internal shaft hole 16 is provided inside the housing 2, and a clamping component 14 is provided inside the internal shaft hole 16. The clamping component 14 is used for the quick installation and limitation of the busbar trunking. The clamping component 14 includes a clamping shaft 141, a bidirectional screw 142, and a limiting sliding shaft 145. The limiting sliding shaft 145 is fixedly installed in the cavity of the housing 2. The clamping shaft 141 is slidably installed inside the internal shaft hole 16. A limiting travel groove 144 is provided on the outer wall of one side of the clamping shaft 141. One end of the limiting sliding shaft 145 is slidably connected to the limiting travel groove 144. The bidirectional screw 142 is threadedly installed inside the clamping shaft 141. A driven meshing shaft 143 is fixedly installed at the middle position of the bidirectional screw 142. A sliding shaft hole is provided at the bottom of the housing 2, and a pressure-bearing meshing shaft 9 is slidably installed inside the sliding shaft hole. One end of the pressure-bearing meshing shaft 9 is located outside the housing 2, and the other end of the pressure-bearing meshing shaft 9 is meshed and connected with the driven meshing shaft 143.

[0053] The specific implementation method is as follows: When installing the busbar trunking, just turn the busbar trunking over so that the housing 2 is embedded in the installation structure. At this time, the pressure-bearing meshing shaft 9 will move inward when touched, and the pressure-bearing meshing shaft 9 can drive the bidirectional screw 142 with the driven meshing shaft 143 to rotate through the meshing action. Since the bidirectional screw 142 has reverse threads, when the bidirectional screw 142 rotates, the clamping shafts 141 at both ends of the bidirectional screw 142 can be simultaneously displaced outward, so that the clamping shafts 141 automatically snap into the card holes on the side of the installation structure to complete the installation.

[0054] Through this design, the quick installation of the busbar trunking can be achieved. The installation is simple and convenient, and the installation can be completed without other installation parts and tools, and the use effect is good.

[0055] Working principle: When the bus duct needs to be installed, it is only necessary to turn the bus duct over so that the shell 2 is embedded in the installation structure. At this time, the pressure-bearing meshing shaft 9 will move inwards under the contact pressure, and the pressure-bearing meshing shaft 9 can drive the two-way stud 142 with the driven meshing shaft 143 to rotate through the meshing action. Since the two-way stud 142 has reverse threads, the two-way stud 142 can simultaneously make the positioning shafts 141 at both ends of the two-way stud 142 move outward at the same time, so that the positioning shaft 141 is automatically stuck in the positioning hole on the side of the installation structure to complete the installation; after the bus duct has been installed and used for a period of time, when a certain amount of dust has accumulated on the lower surface of the bus duct, people can directly The pull ring 171 of the pulling assembly 17 pulls the pulling belt 172. As the pulling belt 172 is pulled down, the take-up reel 173 can rotate, and the reel shaft 174 can rotate synchronously. At this time, the reel shaft 174 can drive the storage roller 105 with the connecting shaft 104 to rotate, and the storage roller 105 can reel in the automatic reel 101 thereon. At this time, the installation brush holder 41 and the cleaning side brush 44 can be pulled to move synchronously. At this time, the connecting spring 43 is stretched. During the displacement process, the cleaning side brush 44 at one end of the installation brush holder 41 can synchronously wipe the surface of the heat dissipation hole, thereby performing a good dust removal and cleaning treatment on the bus duct, avoiding dust clogging the heat dissipation hole, and ensuring heat dissipation efficiency. As a result, when the person releases the pulling belt 172, the stretched connecting spring 43 will retract quickly, causing the installation brush holder 41 to reset, realizing the reciprocating motion of the cleaning component 4, and performing reciprocating cleaning of the bus duct. At the same time, when the cleaning component 4 reciprocates, it can synchronously drive the cylinder rack 34 and the threaded cylinder 35 thereon to move back and forth. Since there is a threaded connection relationship between the threaded cylinder 35 and the threaded shaft 31, the threaded cylinder 35 can drive the heat dissipation and dust cleaning fan 33 to rotate during the displacement process. The rotation of the heat dissipation and dust cleaning fan 33 can generate airflow above the installation brush holder 41, which can effectively take away the heat emitted by the bus duct and ensure the heat dissipation effect of the bus duct. Secondly, it can assist the installation brush holder 41 and the cleaning side brush 44 works to quickly blow off the dust cleaned by the cleaning side brush 44, thereby improving the dust cleaning effect; when the bus duct is normally used, the air flow in the external environment can enter the air inlet and heat dissipation component 7. Due to the oblique setting of the oblique fan blades 75, the air flow entering the air inlet and heat dissipation component 7 can drive the oblique fan blades 75 and the mounting shaft 73 to rotate, so that the air flow can flow quickly in the guide groove 71 set on the inner wall of the air inlet tube 72, and then be conducted to the air flow speed increasing volute 76. After the air flow enters the air flow speed increasing volute 76, due to the narrow air duct design in the air flow speed increasing volute 76, the incoming air flow flows quickly to both sides, and then is guided out, thereby bringing the heat in the bus duct out through the heat dissipation holes 12.
