Description

Technical Field

[0001] This invention relates to the field of cable branch box technology, specifically a cable branch box and its intelligent early warning mechanism. Background Technology

[0002] Cable branch boxes are complete sets of devices in power distribution systems used to reliably transfer and distribute power from main cables to multiple branch cables. Their core function is to safely and systematically branch several lines to supply power to end users without disconnecting the main line. They are usually installed at key nodes of 10kV distribution lines and are composed of insulated busbars, cable joints, grounding protection, and other components. They are characterized by full insulation, full sealing, compact structure, and strong environmental adaptability. They can effectively replace the traditional solution of building distribution rooms or ring main units for branching, significantly saving cable investment and land space. At the same time, cable branch boxes are widely used in residential areas, industrial parks, road lighting, and other scenarios. By configuring fault indicators, surge arresters, and other equipment, they can improve power supply reliability and operation and maintenance convenience. They are one of the important devices for realizing cableization, underground burial, and modularization in urban power distribution networks.

[0003] Currently, cable distribution boxes on the market often experience overheating during operation due to the long-term high load on the internal cable joints. However, most temperature detection mechanisms in cable distribution boxes only detect the internal temperature of the box and cannot detect the temperature of local components. Furthermore, they can only make a rough assessment of the internal temperature and cannot take timely action. Therefore, existing cable distribution boxes cannot provide timely warnings and synchronized operation. Thus, an improved device is needed to address these issues. Summary of the Invention

The second spring is symmetrically fixedly installed between the positioning top frame and the insulating plate, and the second spring is located on the outer ring of the movable vertical rod. The contact copper rod is fixedly installed at the center of the bottom of the insulating plate.

[0009] Specifically, the transmission device includes an intake fan, an L-shaped contact base plate, an extension base frame, a transmission rack, a partition cavity, an arc-shaped sealing plate, a transmission gear, an arc-shaped top frame, and a guide vertical frame. The partition cavity is fixedly installed on the side end of the intake fan, the extension base frame is fixedly installed on both bottom ends of the partition cavity, the transmission gear is rotatably installed on the end of the extension base frame away from the intake fan, the arc-shaped sealing plate is fixedly installed between the two transmission gears, the guide vertical frame is symmetrically fixedly installed on the top of the partition cavity, the arc-shaped top frame is slidably inserted into the interior of the guide vertical frame, the transmission rack is fixedly installed on both bottom ends of the arc-shaped top frame, and the L-shaped contact base plate is fixedly installed on the top of the transmission rack near the side end of the intake fan.

[0010] Specifically, the vertical pipe is fixedly installed at the top of the partition cavity, the air intake fan is fixedly installed on both sides inside the cable branch box, the support cavity is fixedly installed at the bottom of the side of the vertical pipe away from the baffle plate, the transmission rack meshes with the transmission gear, and the connecting base plate is connected to the top of the arc-shaped top frame.

[0011] Specifically, the L-shaped air cylinder is hollow inside, and a sealed cavity is formed between the first piston rod, the L-shaped air cylinder, and the second piston rod. The second piston rod is vertically aligned with the L-shaped contact base plate, and the contact copper rod is vertically aligned with the connecting base plate. The two sides of the contact copper rod are in contact with the first conductive sheet and the second conductive sheet.

[0014] The beneficial effects of this invention are:

[0015] First, this invention uses a temperature sensor to detect high temperatures at a cable branch joint. This triggers a hydraulic cylinder, moving the connecting base plate downwards. The resulting copper contact rod moves between the first and second conductive plates. The first conductive plate is continuously energized, and the second conductive plate is electrically connected to a warning light, activating the warning light to indicate high temperatures at the cable branch joint. Furthermore, two symmetrically positioned warning lights on the outside of the cable branch box allow for separate detection and alarm functions on both sides, providing timely warnings during operation within the cable branch box.

[0016] Second, this invention utilizes the arc-shaped top frame, which, when moving, drives the transmission rack along the surface of the transmission gear, causing the arc-shaped sealing plate to rotate and merge with the partition cavity, thus sealing the partition cavity. At this time, half of the air generated by the intake fan can enter the partition cavity and the interior of the vertical pipe. The vertical pipe aligns with the cable branch joint, allowing the vertical pipe to deliver air to the cable branch joint for cooling. After the cable branch joint temperature decreases, the transmission rack can move in the opposite direction along the surface of the transmission gear, causing the arc-shaped sealing plate to disengage from the partition cavity. This facilitates the intake fan delivering air to the interior of the cable branch box. Furthermore, the baffle plate can move into the interior of the vertical pipe to seal it, preventing air from leaking upwards, thus completing the synchronous cooling process for the cable branch joint.

Through the elasticity of the second spring 21, when the contact copper rod 25 loses its compression, it can be driven to reset.

[0033] like Figure 7The transmission device 6 includes an intake fan 26, an L-shaped contact base plate 27, an extension base frame 28, a transmission rack 29, a partition cavity 30, an arc-shaped sealing plate 31, a transmission gear 32, an arc-shaped top frame 33, and a guide vertical frame 34. The partition cavity 30 is fixedly installed on the side end of the intake fan 26. The extension base frame 28 is fixedly installed on both sides of the bottom end of the partition cavity 30. The transmission gear 32 is rotatably installed on the end of the extension base frame 28 away from the intake fan 26. The arc-shaped sealing plate 31 is fixedly installed between the two transmission gears 32. The guide vertical frame 34 is symmetrically fixedly installed on the top of the partition cavity 30.

The L-shaped contact base plate 27 is fixedly installed on the top of the side end of the transmission rack 29 near the intake fan 26. By setting the partition cavity 30, the air can be divided into two streams when the arc-shaped sealing plate 31 contacts the partition cavity 30.

[0034] The vertical pipe 17 is fixedly installed at the top of the partition cavity 30, the air intake fan 26 is fixedly installed on both sides inside the cable branch box 41, the support cavity 18 is fixedly installed at the bottom of the side of the vertical pipe 17 away from the baffle plate 14, the transmission rack 29 meshes with the transmission gear 32, the connecting base plate 37 is connected to the top of the arc-shaped top frame 33, the L-shaped air cylinder 8 is hollow inside, and a sealed cavity is formed between the first piston rod 7, the L-shaped air cylinder 8 and the second piston rod 10, the second piston rod 10 is vertically aligned with the L-shaped contact base plate 27, the contact copper rod 25 is vertically aligned with the connecting base plate 37, the two sides of the contact copper rod 25 are in contact with the first conductive sheet 23 and the second conductive sheet 24, and the top of the arc-shaped top frame 33 is... Symmetrical openings are provided, and vertical columns are fixedly installed inside the guide frame 34. A through hole is provided at the top of the partition cavity 30. The interior of the partition cavity 30 is hollow. There is an electrical connection between the temperature sensor 40 and the hydraulic cylinder 38. Both sides of the rectifier plate 36 are inclined at 45°. The bottom end of the temperature sensor 40 is connected to the top end of the cable branch connector 35. Heat dissipation holes are provided at equal intervals on both sides inside the cable branch box 41, and the heat dissipation holes are located above the warning light 3. There is a 3 cm gap between the two positioning top frames 19. The air intake fan 26 is interconnected with the partition cavity 30. An arc iron frame is fixedly installed at the bottom end of the temperature sensor 40, and the arc iron frame is connected to the top end of the cable branch connector 35.

[0035] The working principle is as follows: During operation, the cable branch box 41 supplies air to its interior via the intake fan 26, cooling the internal components. Simultaneously, the rectifier plate 36 is horizontally aligned with the intake fan 26, with its sides angled to allow upward airflow. The airflow, carrying heat, is then exhausted through the heat dissipation holes inside the cable branch box 41, further cooling the internal components. Simultaneously, when the cable branch connector 35 is in operation, the temperature sensor 40 contacts the bottom ring of the cable branch connector 35, transferring heat to the ring. The temperature sensor 40 then monitors the temperature of the cable branch connector 35. Temperature detection: When temperature sensor 40 detects a high temperature, it transmits the temperature signal to the controller connected to hydraulic cylinder 38. The controller makes a decision based on a preset temperature threshold, instructing the solenoid directional valve connected to hydraulic cylinder 38 to switch the flow direction of hydraulic oil to drive the piston rod inside hydraulic cylinder 38. At this time, the piston rod inside hydraulic cylinder 38 will drive the connecting base plate 37 to move downwards. In turn, the connecting base plate 37 can drive the arc top bracket 33 and the transmission rack 29 to move downwards synchronously, so that the transmission rack 29 can move along the surface of the transmission gear 32, causing the arc sealing plate 31 to flip upwards. When the connecting base plate 37 moves downwards to its limit position, it can drive the transmission rack 29 to move along the surface of the transmission gear 32 to its full range. This allows the arc-shaped sealing plate 31 to flip upwards and fit against the partition cavity 30, sealing the side of the partition cavity 30 away from the intake fan 26. At this time, half of the air blown by the intake fan 26 can enter the interior of the partition cavity 30. Furthermore, when the arc-shaped top frame 33 moves downwards, it can cause the L-shaped contact base plate 27 to disengage from the second piston rod 10. The elasticity of the first spring 13 will cause the connecting side plate 15 and the baffle plate 14 to move away from the vertical pipe 17, allowing the baffle plate 14 to be extracted from the interior of the vertical pipe 17. At this time, the air inside the partition cavity 30 can be transported upwards through the vertical pipe 17. By aligning the vertical pipe 17 perpendicularly with the cable branch connector 35, the cable branch connector 35 can be cooled. Simultaneously, when the connecting base plate 37 moves downward to its limit position, it can also press the contact copper rod 25 to move downward synchronously until it contacts the first conductive piece 23 and the second conductive piece 24. The first conductive piece 23 is connected to the external power supply, and the second conductive piece 24 is electrically connected to the warning light 3. When the contact copper rod 25 contacts the first conductive piece 23 and the second conductive piece 24, the warning light 3 can be powered on and illuminated to warn that the cable branch joint 35 inside the cable branch box 41 is overheating. After the cable branch joint 35 is cooled to a safe range by the air blown by the vertical pipe 17, the controller can instruct the piston rod inside the hydraulic cylinder 38 to reset. When the connecting base plate 37 resets upward, the connecting base plate 37 can disengage from the contact copper rod 25.The elasticity of the second spring 21 causes the insulating plate 22 to move upward and reset, allowing the contact copper rod 25 to disengage from the first conductive plate 23 and the second conductive plate 24, thus de-energizing the warning light 3. Simultaneously, the connecting base plate 37 also causes the transmission rack 29 to move upward, enabling it to drive the transmission gear 32 and the arc-shaped sealing plate 31 to rotate in the opposite direction. This allows the arc-shaped sealing plate 31 to rotate to a horizontal position, at which point all the air blown by the intake fan 26 can enter the cable branch box 41, improving its cooling efficiency. Furthermore, when the transmission rack 29 moves upward to its limit position, the L-shaped contact base plate 27 can compress the second piston rod 10, allowing it to fully enter the irregular connecting rod 9. This allows the first piston rod 7 to drive the flow-blocking plate 14 into the vertical pipe 17 via the irregular connecting rod 9, thus sealing the interior of the vertical pipe 17 and preventing air from the partition cavity 30 from continuing to be transported through the vertical pipe 17. The connecting side plate 15 is slidably fitted onto the outer ring of the guide rod 16. This allows the flow-supporting baffle plate 14 to move in a straight line, improving the accuracy of its movement and completing the task. During use, the device slides through the internal sleeve of the arc-shaped top frame 33 onto the vertical column inside the guide frame 34, allowing the arc-shaped top frame 33 to move in a straight line. Simultaneously, the movable vertical rod 20 slides inside the positioning top frame 19, allowing the insulating plate 22 to move in a straight line. Furthermore, the insulating plate 22 prevents electrical leakage from contacting the copper rod 25, improving the safety of the device during operation. When the arc-shaped sealing plate 31 merges with the partition cavity 30, it separates the air supplied by the intake fan 26, allowing half of the air to be supplied through the vertical pipe 17 to contact the cable branch connector 35. After the cable branch connector 35 has cooled down, the arc-shaped sealing plate 31 returns to its original position until it is horizontal, allowing all the air supplied by the intake fan 26 to enter the interior of the cable branch box 41, cooling the components inside. ,
