Description

Technical Field

[0001] This invention relates to the field of JP cabinet busbar connector technology, and more particularly to a temperature detection device for JP cabinet busbar connectors. Background Technology

[0002] JP cabinets, also known as JP integrated distribution boxes, are a type of distribution cabinet. Distribution cabinets are low-voltage power distribution devices that assemble switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements.

[0003] To ensure the effectiveness of circuit connections, busbar connector assemblies are often used. The busbar trunking inside the busbar connector assembly is a closed metal device made of copper and aluminum busbar columns, used to distribute a large amount of power to various components of the distributed system. The sections of the busbar trunking are generally connected and conductive through connectors. Traditional connector products consist of multiple insulating partitions and multiple conductive connecting plates spaced apart, which are then fixed together by connector bolts and nuts. The multiple insulating partitions have different structural shapes, and a butterfly spring and a connector pressure plate are sequentially installed on the outermost insulating partition. An insulating sleeve is also installed on the outside of the connector bolts.

[0004] In practice, circuit connection can cause circuit heating. Conventional distribution cabinets have poor heat dissipation, which leads to an increase in temperature inside the JP cabinet. The busbar connector assembly is the most severely affected by overheating, which is detrimental to the safe operation of the equipment. Furthermore, conventional JP cabinets are single units with limited specifications, and cannot be combined with multiple JP cabinets when expansion is needed. Therefore, improvements are required. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a temperature detection device for busbar joints in JP cabinets.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A temperature detection device for busbar joints in a JP cabinet includes a base, and multiple cabinets are arranged from bottom to top on the upper end of the base; A door panel assembly is hinged to one side of the cabinet. A circulation detection mechanism is installed on one side of the door panel assembly. A temperature detection component is provided on the circulation detection mechanism and is located inside the door panel assembly. A connection mechanism is provided between the base and the cabinet. An air guide hood is fixed to the rear end of the cabinet. An air supply and exhaust mechanism is connected to the air guide hood and the base at the bottom end. A heat-conducting bearing plate is installed inside the cabinet. A busbar connector assembly is installed on the upper end of the heat-conducting bearing plate. An exhaust and heat dissipation mechanism is provided on the heat-conducting bearing plate and the cabinet. The heat-conducting support plate inside the cabinet and the air guide hood located at the rear end of the cabinet are jointly provided with a ventilation mechanism. The heat-conducting support plate is provided with a coil, which is connected to the exhaust heat dissipation mechanism and the ventilation mechanism. The air guide hood is equipped with a linkage mechanism, the linkage mechanism is equipped with a partition, and the partition is equipped with a ventilation mechanism.

[0007] Compared with existing technologies, this invention enables overlapping installation of the base and multiple cabinets, allowing for cabinet assembly as needed, improving practicality. After assembly, the corresponding air guide covers form a whole, enabling heat exchange between the upper and lower components of the busbar connector assembly, effectively reducing the temperature of the busbar connector assembly. Simultaneously, multi-position temperature detection is performed through temperature detection components to accurately understand the temperature at various locations within the cabinet, thereby controlling heat dissipation efficiency, effectively controlling the temperature within the cabinet, and ensuring stable operation of the busbar connector assembly.

[0008] Preferably, the linkage mechanism includes two mounting cavities disposed within the air guide hood, the partition being located between the two mounting cavities, and connection ports being provided at the top and bottom of each mounting cavity. The connection ports are disposed on the air guide hood. The top and bottom of one side wall of each mounting cavity are provided with movable vertical grooves, and an arc-shaped groove is provided in the middle of the movable vertical groove. A small roller is disposed in the arc-shaped groove, and a large roller is disposed in the movable vertical groove. A sealing baffle is connected between the small roller and the large roller on the same side. The sealing baffle is disposed at the lower end of the connection port, and a pressing mechanism is provided on the connection port.

[0009] Preferably, the air supply and exhaust mechanism includes two connecting valve pipes that pass through both sides of the lower end of the air guide cover. The connecting valve pipes are located on the side of the air guide cover away from the cabinet. An air pump assembly is installed at the upper end of the base. An air supply pipe is connected to the upper end of the air pump assembly. The air supply pipe is connected to a connecting valve pipe located on the lower end of the air guide cover.

[0010] Furthermore, the connecting valve fitting consists of a pipe body and a control valve assembly mounted on the pipe body. The pipe body inside the connecting valve fitting is installed through the air guide shroud, and two connecting valve fittings are installed through the lower ends of the air guide shroud on both sides. The two ends of the pipe body of the two connecting valve fittings extend into the two mounting cavities inside the air guide shroud, respectively. In actual preparation, the two gas guide hoods at the bottom are both through-hole to facilitate gas flow. At the same time, one of them is connected to the gas supply pipe, which facilitates the rapid entry of gas into the gas guide hood through the gas pump assembly. Meanwhile, the upper end of the connecting valve pipe connected to the gas supply pipe corresponds to the gas inlet hood, which also facilitates the rapid entry of gas into the gas inlet hood.

[0011] Preferably, the exhaust and heat dissipation mechanism includes two exhaust plates fixed on both sides of the cabinet body. The exhaust plates are flush with the side walls of the cabinet body. A connecting hole is opened at the lower end of the exhaust plate. Elastic telescopic tubes are installed on both sides of the coil fitting. The two elastic telescopic tubes are respectively inserted into the two connecting holes located in the same cabinet body. The cabinet is equipped with filter windows on both sides of its lower end, and the filter windows are located at the lower end of the heat-conducting bearing plate. The cyclic detection mechanism includes a motor assembly installed on one side of the door panel assembly. Synchronous pulleys are installed at the end of the output shaft of the motor assembly and on one side of the upper end of the door panel assembly. The two synchronous pulleys are connected by a synchronous belt drive. A connecting member is rotatably connected to the synchronous belt. A lifting plate is rotatably connected to one side of the connecting member. The lifting plate is slidably installed on the door panel assembly. A lead screw is rotatably sleeved on the lifting plate. The temperature detection component is threaded onto the lead screw and slidably installed on the lifting plate. A gear is fixed to one end of the lead screw, and a spur rack is fixed to the upper end, with the gear and the spur rack meshing together.

[0012] Furthermore, the staff installs the heat-conducting support plate into the cabinet. As the heat-conducting support plate moves, the elastic expansion tube retracts into the heat-conducting support plate. After the heat-conducting support plate is installed in place, the elastic expansion tube can be removed from the coil fitting and busbar connector assembly and inserted into the connecting hole. When the gas in the coil fitting flows, it enters the vent plate through the elastic expansion tube and the connecting hole. The gas is discharged to the upper end of the heat-conducting support plate through the vent plate, then moves down through the through-hole on the busbar connector assembly, and is discharged through the filter window. The gas flow can reduce the temperature of the busbar connector assembly. Simultaneously, the motor assembly drives the synchronous pulley fixedly connected to it to rotate. When the synchronous pulley rotates through the synchronous belt, it causes another synchronous pulley to rotate. Both the synchronous belt and the synchronous pulley adopt a toothed structure. Through the meshing of the teeth, stable power transmission can be ensured, allowing the synchronous belt to circulate. The synchronous belt can drive the lifting plate to move through the connecting parts. The lifting plate is slidably installed on one side of the door panel assembly, allowing the lifting plate to rise and fall smoothly. The lifting plate can drive the lead screw to rise and fall, causing the gear to rotate under the action of the rack. In actual operation, when the gear moves up or down, the direction of rotation of the lead screw is different. Through different rotation directions, the temperature detection component can move smoothly along the lifting plate. That is, the temperature detection component can detect the temperature at multiple locations inside the cabinet to understand the temperature of the busbar connector assembly.

[0013] Preferably, the ventilation mechanism includes two insertion pipes that pass through the rear end of the cabinet. The two insertion pipes extend into two mounting cavities located in the air guide hood at the rear end of the cabinet. One end of one of the cabinets is fixed with an air inlet hood, which is located in one of the mounting cavities. The coil is passed through the busbar connector assembly, and multiple through-holes are equally spaced on both sides of the busbar connector assembly.

[0014] Furthermore, during the installation of the heat-conducting support plate, busbar connector assemblies extend from both ends of the coil fitting. After the heat-conducting support plate is installed in place, both ends of the coil fitting are inserted into the corresponding connectors. As the gas passes through the air pump assembly and the corresponding installation chamber of the air supply pipe, the gas rises and connects to the corresponding air inlet hood. This allows the gas to enter the coil fitting through the air inlet hood and the connector fixed to it, facilitating gas circulation within the coil fitting. The gas can then be discharged through the other end of the coil fitting to another installation chamber, and then discharged through the connecting valve fitting in the other installation chamber, thus achieving gas circulation.

[0015] Preferably, the ventilation mechanism includes an air exchange port opened at the upper end of the partition, a spring member is fixed at the bottom of the air exchange port, a sealing plate is fixed at the upper end of the spring member, the sealing plate is slidably installed in the air exchange port, and a pressure rod member is fixed at the upper end of the sealing plate. The upper end of the pressure rod member passes through the partition and the air guide hood and extends to the upper end of the air guide hood.

[0016] Furthermore, when there are many power distribution components required, multiple cabinets need to be installed. This application enables multiple cabinets to be stacked. When another cabinet is installed on the cabinet connected to the base, the pressure rod at the lower end will descend, which will cause the pressure rod to drive the sealing plate to descend and close the air exchange port. This allows the air exchange port in the uppermost air guide hood to be open. In this way, the gas entering through the air pump assembly and air supply pipe will enter the installation cavity on the other side from the air exchange port in the uppermost air guide hood and be discharged, thus realizing the gas circulation operation.

[0017] Preferably, the extrusion mechanism includes a linkage frame slidably mounted on the top and bottom of the mounting cavity. A pressure plate is fixed to one end of the linkage frame extending to the outside of the air guide hood. A movable winding wheel assembly is fixed to one end of the linkage frame located in the mounting cavity. A fixed winding wheel assembly is mounted on one side wall of the mounting cavity. Two fixed winding wheel assemblies located in the same mounting cavity are located outside two movable winding wheel assemblies. A pull rope is wound on both the movable winding wheel assembly and the fixed winding wheel assembly on the same side. One end of the pull rope is fixedly connected to one end of the movable winding wheel assembly. One end of the pull rope is fixedly connected to a sealing baffle on the same side. A tension spring is fixed to both the sealing baffle and the side wall above the mounting cavity.

[0018] Furthermore, when the two cabinets are stacked, the upper air guide hood will press against the lower air guide hood, causing the pressure plate to be pressed down. The pressure plate can drive the movable winding wheel assembly to descend via the linkage frame. Both the movable and fixed winding wheel assemblies consist of multiple winding wheels. At the same time, the pull rope is wound around the multiple winding wheels in the movable and fixed winding wheel assemblies. When the movable winding wheel assembly moves, the pull rope can pull the sealing baffle to move. The small and large rollers on the sealing baffle can ensure the stability of the sealing baffle's movement. The tension spring can facilitate the quick reset of the sealing baffle when there is no external pressure, so as to realize the sealing operation inside the air guide hood.

[0019] Preferably, the depth of the arc-shaped groove is greater than the depth of the moving vertical groove, the width of the arc-shaped groove is less than the width of the moving vertical groove, the length of the small roller is greater than the length of the large roller, and the diameter of the small roller is less than the diameter of the large roller.

[0020] Furthermore, ensuring that the small rollers move within the arc-shaped groove and the large rollers move within the vertical moving groove guarantees the stability of the sealing baffle's movement.

[0021] Preferably, the connecting mechanism includes four mounting rods fixed to the four corners of the upper end of the base, and positioning holes are provided at the four corners of the lower end of the cabinet. The four mounting rods are respectively located in the four positioning holes in the lowermost cabinet. The cabinet has mounting cavities on both sides of its upper end. Elastic telescopic components are installed on both sides of each mounting cavity. Positioning rods are slidably installed on the elastic telescopic components. An adjustment mechanism is provided at the upper end of each mounting cavity. Two pull rods are connected to the adjustment mechanism. The two pull rods located in the same mounting cavity are rotatably connected to the lower ends of the two positioning rods respectively.

[0022] Furthermore, by controlling the operation of the regulating mechanism, the position of the sliding plate can be controlled. When the sliding plate is not fixed in the mounting cavity, the positioning rod can be raised by the elastic telescopic component, so that four positioning rods can extend from the lower cabinet to connect with the upper cabinet. These four positioning rods can be inserted into the four positioning holes in the upper cabinet to complete the stacking of multiple cabinets and ensure the stability of the stacking.

[0023] Preferably, the control mechanism includes two sliding plates that are slidably mounted on the top of the mounting cavity. The sliding plates and the mounting cavity are connected together by a positioning component, and the upper ends of the two pull rods are rotatably connected to the lower ends of the two sliding plates.

[0024] Furthermore, the positioning component consists of a rod and a corresponding hole. The hole can be set on the mounting cavity. By controlling the positional relationship between the rod and the hole, the movement of the sliding plate can be effectively controlled. When the sliding plate can move, the elastic telescopic component will operate. When the sliding plate is fixed, the positioning rod will retract into the mounting cavity to ensure the flatness of the upper part of the cabinet.

[0025] The beneficial effects of this invention are: 1. The motor assembly can drive the synchronous pulley fixedly connected to it to rotate. When the synchronous pulley rotates through the synchronous belt, it causes another synchronous pulley to rotate. Both the synchronous belt and the synchronous pulley adopt a toothed structure. Through the meshing of the teeth, the stable transmission of power can be ensured, and the synchronous belt can circulate. The synchronous belt can drive the lifting plate to move through the connecting parts. The lifting plate is slidably installed on one side of the door panel assembly, which can make the lifting plate rise and fall smoothly. The lifting plate can drive the lead screw to rise and fall, so that the gear can rotate under the action of the rack. In actual operation, when the gear moves up or down, the direction of rotation of the lead screw is different. Through different rotation directions, the temperature detection component can move smoothly along the lifting plate. That is, the temperature detection component can detect the temperature at multiple locations inside the cabinet in order to understand the temperature of the bus joint assembly. 2. When installing the heat-conducting support plate, busbar connector assemblies will extend from both ends of the coil fitting. After the heat-conducting support plate is installed in place, the two ends of the coil fitting are inserted into the corresponding insertion pipes. As the gas passes through the air pump assembly and the corresponding installation cavity of the air supply pipe, the gas rises and connects to the corresponding air inlet hood. The gas enters the coil fitting through the air inlet hood and the insertion pipe fixed to it, which facilitates the circulation of gas within the coil fitting. The gas can be discharged through the other end of the coil fitting to another installation cavity, and then discharged through the connecting valve fitting in the other installation cavity, realizing the circulation of gas. The flow of gas can carry away heat. 3. The cabinets can be stacked to reduce the area they occupy. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Reference Figures 1-9 A temperature detection device for busbar connectors in a JP cabinet includes a base 1, with multiple cabinets 2 arranged from bottom to top on the upper end of the base 1. The arrangement of multiple cabinets 2 allows for configuration as needed to fully meet power requirements and reduce the load on individual components, thereby improving safety. Corresponding components are installed inside the cabinets 2 for installation with matching parts, enabling the connection and fixation of the busbar connectors. The busbar connectors are conventionally designed to facilitate the insertion of corresponding components and ensure circuit continuity.

[0029] In this embodiment, a door panel assembly 4 is hinged to one side of the cabinet 2. A circulation detection mechanism is installed on one side of the door panel assembly 4. A temperature detection component 50 is provided on the circulation detection mechanism and is located inside the door panel assembly 4. The circulation detection mechanism can detect the temperature at multiple locations inside the cabinet 2. The temperature detection component 50 uses existing technology components and can upload the detected temperature information. A connection mechanism is provided between the base 1 and the cabinet 2. An air guide hood 25 is fixed at the rear end of the cabinet 2. An air supply and exhaust mechanism is connected to the air guide hood 25 at the bottom end and the base 1. A heat-conducting bearing plate 6 is installed inside the cabinet 2. A busbar connector assembly 5 is installed on the upper end of the heat-conducting bearing plate 6. The busbar connector assembly 5 can be connected to the matching plug-in component to ensure sufficient contact and facilitate power transmission. An exhaust and heat dissipation mechanism is provided on the heat-conducting bearing plate 6 and the cabinet 2. The exhaust and heat dissipation mechanism enables the gas to flow in a directional manner to facilitate heat dissipation.

[0030] In this embodiment, the heat-conducting support plate 6 inside the cabinet 2 and the air guide hood 25 located at the rear end of the cabinet 2 are jointly provided with a ventilation mechanism. The heat-conducting support plate 6 is provided with a coil 20, which is connected to the exhaust heat dissipation mechanism and the ventilation mechanism. The air guide hood 25 is provided with a linkage mechanism, which is provided with a partition, and the partition is provided with a ventilation mechanism. Through the cooperation of multiple mechanisms, gas can flow in the equipment to facilitate heat dissipation.

[0031] In this embodiment, the linkage mechanism includes two mounting cavities disposed within the air guide hood 25. A partition divides the air guide hood 25 into two cavities. When multiple cabinets 2 are stacked, the cavities within the air guide hood 25 also overlap, as do the overlapping cavities between multiple air guide hoods 25, and the partition also overlaps. This allows the cavities on both sides of the partition to be connected, enabling gas to flow within the wall. Simultaneously, the ventilation port 32 on the uppermost partition allows gas flow, causing gas to flow upwards from the mounting cavity on one side of the connecting valve fitting 26 connected to the air supply pipe 14, move through the ventilation port 32 to the mounting cavity on the other side, and then flow downwards through the lowermost mounting cavity on that side. The gas is discharged through the connecting valve fitting 26, which fully realizes the circulation of gas. The partition is located between the two installation chambers. The top and bottom of the installation chambers are provided with connection ports 33. The connection ports 33 are set on the gas guide cover 25. The top and bottom of one side wall of the installation chamber are provided with movable vertical grooves 29. The middle of the movable vertical groove 29 is provided with an arc groove 28. The arc groove 28 is provided with a small roller 38. The movable vertical groove 29 is provided with a large roller 37. The small roller 38 and the large roller 37 on the same side are connected to a sealing baffle 36. The sealing baffle 36 is located at the lower end of the connection port 33. In actual production, the sealing baffle 36 can be covered with rubber material, which can be squeezed to effectively seal.

[0032] In this embodiment, the air supply and exhaust mechanism includes two connecting valve pipes 26 that pass through both sides of the lower end of the air guide hood 25. The connecting valve pipes 26 are located on the side of the air guide hood 25 away from the cabinet 2. An air pump assembly 15 is installed on the upper end of the base 1. In actual operation, the power of the air pump assembly 15 can be controlled, as can the gas flow rate and flow speed, in order to control the heat dissipation effect. An air supply pipe 14 is connected to the upper end of the air pump assembly 15. The air supply pipe 14 is connected to a connecting valve pipe 26 located on the lower end of the air guide hood 25. The connecting valve pipe 26 consists of a pipe body and a control valve assembly installed on the pipe body. The pipe inside the connecting valve pipe 26... The body is installed through the gas guide hood 25, and two connecting valve pipes 26 are installed through the lower two sides of the gas guide hood 25. The two ends of the connecting valve pipes 26 extend into the two mounting cavities inside the gas guide hood 25. In actual preparation, the two at the bottom of the gas guide hood 25 are connected to each other to facilitate gas flow. At the same time, one of the connecting valve pipes 26 is connected to the gas supply pipe 14 to facilitate the rapid entry of gas into the gas guide hood 25 through the air pump assembly 15. In actual preparation, the upper end of the connecting valve pipe 26 connected to the gas supply pipe 14 corresponds to the air inlet hood 17 to facilitate the rapid entry of gas into the air inlet hood 17.

[0033] In this embodiment, the exhaust and heat dissipation mechanism includes two exhaust plates 9 fixed on both sides inside the cabinet 2. The exhaust plates 9 are flush with the side walls of the cabinet 2. A connecting hole 10 is opened at the lower end of the exhaust plate 9. Elastic telescopic tubes 19 are installed on both sides of the coil fitting 20. The two elastic telescopic tubes 19 are respectively inserted into the two connecting holes 10 located in the same cabinet 2. Filter windows 3 are installed on both sides of the lower end of the cabinet 2. The filter windows 3 are located at the lower end of the heat-conducting support plate 6. The operator installs the heat-conducting support plate 6 into the cabinet 2. As the heat-conducting support plate 6 moves, the elastic telescopic tube 19 can retract into the heat-conducting support plate 6. After the heat-conducting support plate 6 is installed in place, the elastic telescopic tube 19 can be removed from the coil fitting 20 and the busbar connector assembly 5 and inserted into the connecting hole 10. When the gas in the coil fitting 20 flows, it will enter the air outlet plate 9 through the elastic telescopic tube 19 and the connecting hole 10. The gas is discharged to the upper end of the heat-conducting support plate 6 through the air outlet plate 9, and then moves down through the through hole 18 on the busbar connector assembly 5 and is discharged through the filter window 3. The cyclic detection mechanism includes a motor assembly 46 installed on one side of the door panel assembly 4. Synchronous pulleys 47 are installed at the end of the output shaft of the motor assembly 46 and on the upper side of the door panel assembly 4. The two synchronous pulleys 47 are connected by a synchronous belt 45. A connecting piece 44 is rotatably connected to the synchronous belt 45. A lifting plate 48 is rotatably connected to one side of the connecting piece 44. The lifting plate 48 is slidably installed on the door panel assembly 4. A lead screw 49 is rotatably sleeved on the lifting plate 48. A temperature detection component 50 is threaded onto the lead screw 49. The temperature detection component 50 is slidably installed on the lifting plate 48. A gear 43 is fixed to one end of the lead screw 49, and a rack 42 is fixed to it. The gear 43 and the rack 42 mesh with each other. The motor assembly 46 can drive the synchronous pulley 47, which is fixedly connected to it, to rotate. When the synchronous pulley 47 rotates through the synchronous belt 45, the other synchronous pulley 47 rotates. Both the synchronous belt 45 and the synchronous pulley 47 are toothed. Through the meshing of the teeth, the stable transmission of power is ensured, and the synchronous belt 45 can circulate. The synchronous belt 45 can drive the lifting plate 48 to move through the connecting member 44. The lifting plate 48 slides. Installed on one side of the door panel assembly 4, the lifting plate 48 can be raised and lowered smoothly. The lifting plate 48 can drive the lead screw 49 to rise and fall, causing the gear 43 to rotate under the action of the rack 42. In actual operation, when the gear 43 moves up or down, the direction of rotation of the lead screw 49 is different. Through different rotation directions, the temperature detection component 50 can move smoothly along the lifting plate 48. That is, the temperature detection component 50 can detect the temperature at multiple locations inside the cabinet 2 in order to understand the temperature of the busbar connector assembly.

[0034] In this embodiment, the ventilation mechanism includes two through-pipes 16 disposed at the rear end of the cabinet 2. The two through-pipes 16 extend into two mounting cavities disposed within the air guide hood 25 at the rear end of the cabinet 2. One end of one of the cabinet 2 is fixed with an air inlet hood 17, which is located within one of the mounting cavities. The coil fitting 20 is disposed through the busbar connector assembly 5. Multiple through-holes 18 are equally spaced on both sides of the busbar connector assembly 5. When the heat-conducting bearing plate 6 is installed, both ends of the coil fitting 20 extend out of the busbar connector assembly 5. After the heat-conducting support plate 6 is installed in place, both ends of the coil fitting 20 are inserted into the corresponding insertion pipe 16. As the gas passes through the air pump assembly 15 and the corresponding installation cavity of the air supply pipe 14, the gas rises and connects to the corresponding air inlet hood 17, allowing the gas to enter the coil fitting 20 through the air inlet hood 17 and the insertion pipe 16 fixed thereto. This facilitates the circulation of gas within the coil fitting 20. The gas can be discharged through the other end of the coil fitting 20 to another installation cavity, and then discharged through the connecting valve fitting 26 in the other installation cavity, thus realizing the circulation of gas.

[0035] In this embodiment, the ventilation mechanism includes an air exchange port 32 located at the upper end of the partition. A spring member 31 is fixed to the bottom of the air exchange port 32, and a sealing plate 30 is fixed to the upper end of the spring member 31. The sealing plate 30 is slidably installed inside the air exchange port 32. A pressure rod member 27 is fixed to the upper end of the sealing plate 30. The upper end of the pressure rod member 27 passes through the partition and the air guide hood 25 and extends to the upper end of the air guide hood 25. In actual operation, the JP cabinet busbar connector will generate a large amount of heat when it is in operation. When there is a large amount of electricity or electrical equipment, and multiple JP cabinets are required, To reduce space requirements, multiple cabinets 2 can be stacked. When another cabinet 2 is installed on the cabinet 2 connected to the base 1, the pressure rod 27 at the lower end will descend, causing the pressure rod 27 to drive the sealing plate 30 to descend and close the air exchange port 32. This allows the air exchange port 32 in the uppermost air guide hood 25 to be open, so that the gas entering through the air pump assembly 15 and the air supply pipe 14 will enter the installation cavity on the other side from the air exchange port 32 in the uppermost air guide hood 25 and be discharged, thus realizing the gas circulation operation.

[0036] In this embodiment, the extrusion mechanism includes a linkage frame 24 slidably mounted on the top and bottom of the mounting cavity. A pressure plate 34 is fixed to one end of the linkage frame 24 extending to the outside of the air guide hood 25. A movable winding wheel assembly 22 is fixed to one end of the linkage frame 24 within the mounting cavity. A fixed winding wheel assembly 23 is mounted on one side wall of the mounting cavity. Two fixed winding wheel assemblies 23 located in the same mounting cavity are located outside the two movable winding wheel assemblies 22. A pull rope 35 is wound around both the movable winding wheel assembly 22 and the fixed winding wheel assembly 23 on the same side. One end of the pull rope 35 is fixedly connected to one end of the movable winding wheel assembly 22, and another end of the pull rope 35 is fixedly connected to a sealing baffle 36 on the same side. A tension spring 21 is fixed to both the sealing baffle 36 and the side wall above the mounting cavity. When When the two cabinets 2 are stacked, the upper air guide hood 25 will press against the lower air guide hood 25, causing the pressure plate 34 to be pressed down. The pressure plate 34 can drive the movable winding wheel assembly 22 to descend through the linkage frame 24. Both the movable winding wheel assembly 22 and the fixed winding wheel assembly 23 are composed of multiple winding wheels. At the same time, the pull rope 35 is wound around the multiple winding wheels in the movable winding wheel assembly 22 and the fixed winding wheel assembly 23 in sequence. When the movable winding wheel assembly 22 moves, the pull rope 35 can pull the sealing baffle 36 to move. The small roller 38 and large roller 37 on the sealing baffle 36 can ensure the stability of the movement of the sealing baffle 36. The tension spring 21 can facilitate the quick reset of the sealing baffle 36 when there is no external pressure, so as to realize the sealing operation installed inside the air guide hood 25.

[0037] In this embodiment, the depth of the arc-shaped groove 28 is greater than the depth of the moving vertical groove 29, the width of the arc-shaped groove 28 is less than the width of the moving vertical groove 29, the length of the small roller 38 is greater than the length of the large roller 37, and the diameter of the small roller 38 is less than the diameter of the large roller 37; this ensures that the small roller 38 moves within the arc-shaped groove 28 and the large roller 37 moves within the moving vertical groove 29, thus guaranteeing the stability of the movement of the sealing baffle 36.

[0038] In this embodiment, the connecting mechanism includes four mounting rods 13 fixed to the four corners of the upper end of the base 1. Positioning holes 12 are provided at the four corners of the lower end of the cabinet 2, and the four mounting rods 13 are respectively located within the four positioning holes 12 inside the lowermost cabinet 2. Mounting cavities 11 are provided on both sides of the upper end of the cabinet 2. Elastic telescopic components 8 are installed on both sides of each mounting cavity 11, and positioning inserts 7 are slidably mounted on the elastic telescopic components 8. An adjustment mechanism is provided at the upper end of the mounting cavity 11, and two pull rods 41 are connected to the adjustment mechanism, located within the same mounting cavity 11. Pull rod 41 is rotatably connected to the lower ends of two positioning insert rods 7 respectively; through the operation of the control mechanism, the position of the sliding plate 40 can be controlled. When the sliding plate 40 is not fixed to the mounting cavity 11, the positioning insert rod 7 can be raised through the elastic telescopic component 8, so that four positioning insert rods 7 can extend from the lower cabinet 2 to dock with the upper cabinet 2. These four positioning insert rods 7 can be inserted into the four positioning holes 12 in the upper cabinet 2 to complete the stacking of multiple cabinets 2 and ensure the stability of the stacking.

[0039] In this embodiment, the control mechanism includes two sliding plate parts 40 slidably installed on the top of the mounting cavity 11. The sliding plate parts 40 and the mounting cavity 11 are connected to a positioning component 39. The upper ends of the two pull rods 41 are respectively rotatably connected to the lower ends of the two sliding plate parts 40. The positioning component 39 consists of a plug rod and a corresponding hole. The hole can be set on the mounting cavity 11. By the positional relationship between the plug rod and the hole, the movement of the sliding plate parts 40 can be effectively controlled. When the sliding plate parts 40 can move, the elastic telescopic component 8 will operate. When the sliding plate parts 40 are fixed, the positioning plug rod 7 is retracted into the mounting cavity 11 to ensure the flatness of the upper end of the cabinet 2.

[0040] In this invention, the motor assembly 46 can drive the synchronous pulley 47 fixedly connected to it to rotate. When the synchronous pulley 47 rotates through the synchronous belt 45, and both the synchronous belt 45 and the synchronous pulley 47 adopt a toothed structure, the meshing of the teeth can ensure the stable transmission of power and enable the synchronous belt 45 to circulate. The synchronous belt 45 can drive the lifting plate 48 to move through the connecting member 44. The lifting plate 48 is slidably installed on one side of the door panel assembly 4, which can make the lifting plate 48 rise and fall smoothly. The lifting plate 48 can drive the lead screw 49 to rise and fall, so that the gear 43 rotates under the action of the rack 42. In actual operation, when the gear 43 moves up or down, the rotation direction of the lead screw 49 is different. Through different rotation directions, the temperature detection component 50 can move smoothly along the lifting plate 48. That is, the temperature detection component 50 can detect the temperature at multiple locations inside the cabinet 2 in order to understand the temperature of the busbar connector assembly; and it can also allow the air to flow and perform heat dissipation.
