Description

Technical Field

[0001] This utility model belongs to the field of lightning protection technology, specifically a branch line lightning protection base. Background Technology

[0002] A lightning protection base is a lightning protection device used in electrical equipment or communication facilities. Its main function is to guide lightning current from the equipment to the ground. Especially in thunderstorms or areas with frequent lightning strikes, it can effectively prevent lightning from directly or indirectly damaging electrical equipment or communication systems. It is a key lightning protection device to ensure the safety of power, communication and other facilities.

[0003] Existing surge protection bases and surge protection cabinets are mostly fixed with screws or welded. When a surge protection base malfunctions and needs to be repaired, a lot of time is required to disassemble the surge protection base.

[0004] When using screws for fastening, the screws usually need to be tightened with high torque, and there are often many of them. When exposed to the outdoor environment for a long time, the screws will rust and corrode, requiring a lot of force to remove them. Inspectors often need to carry tools such as blowtorches, rust removers, impact screwdrivers, and even electric drills to deal with the rusted screws, making the whole process time-consuming and labor-intensive.

[0005] While welding provides better electrical continuity and strength, it also means that maintenance and replacement inevitably require the use of cutting tools such as angle grinders and acetylene torches, which poses greater safety hazards and takes longer. Therefore, pluggable surge protection modules are the more mainstream solution. Summary of the Invention

[0006] To address the problem mentioned in the background art that a significant amount of time is required to disassemble the lightning protection base during maintenance, this utility model provides a branch line lightning protection base.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a split-line lightning protection base, comprising a first mounting plate, a second mounting plate movably connected to the bottom surface of the first mounting plate, a conductive copper busbar fixedly mounted on the top surface of the second mounting plate, mounting components provided on both sides of the first mounting plate, a lightning protection connector fixedly mounted in the middle of the top surface of the second mounting plate, a plurality of mounting holes opened on the top surface of the first mounting plate, a plurality of split-line terminals provided on the surface of the second mounting plate, the mounting components comprising connecting columns, the connecting columns being fixedly connected to the second mounting plate, movable units movably connected to both sides of the first mounting plate, and fixed units fixedly mounted on both sides of the first mounting plate.

[0008] Preferably, the moving unit includes a moving block, a first spring is fixedly installed between the moving block and the first mounting plate, a moving rod is fixedly installed on one side of the moving block, a limit block is movably connected to the lower end of the moving rod, and a tension spring is fixedly installed between the limit block and the moving rod.

[0009] Preferably, the fixing unit includes a fixing plate, and a second spring is fixedly installed between the fixing plate and the first mounting plate, and the fixing plate and the first mounting plate are movably connected.

[0010] Preferably, the second mounting plate has limit grooves on both sides, and the limit block and the limit groove are movably connected.

[0011] Preferably, the side of the movable rod closest to the fixed plate is set as an arc surface, and the end of the fixed plate closest to the movable rod is set as an arc surface, with the movable rod and the fixed plate in abutting connection.

[0012] Preferably, grooves are provided on both sides of the upper end of the connecting column, the moving block is movably connected to the grooves, and the moving rod is movably connected to the first mounting plate.

[0013] Preferably, both the first mounting plate and the second mounting plate are made of stainless steel, and a handle is provided on the outer side of the moving rod.

[0014] The beneficial effects of this utility model are as follows: This utility model allows maintenance personnel to replace or repair the entire second mounting plate functional module without touching the wiring of the surge protector cabinet. The moving unit and the fixed unit work together to release the limiting block from the limiting groove of the second mounting plate. Pulling the moving rod to both sides causes it to contact the second spring, which moves downwards. After moving a certain distance, the moving block releases the connecting column, quickly separating the first and second mounting plates. This allows for rapid maintenance of the second mounting plate, avoiding the time-consuming disassembly and maintenance of the branch surge protector base, and reducing operational complexity and the risk of electric shock.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 5 As shown, this utility model provides a split-line surge protector base, including a first mounting plate 1, a second mounting plate 2 movably connected to the bottom surface of the first mounting plate 1, a conductive copper busbar 3 fixedly mounted on the top surface of the second mounting plate 2, mounting components 4 provided on both sides of the first mounting plate 1, a surge protector connector 5 fixedly mounted in the middle of the top surface of the second mounting plate 2, a plurality of mounting holes 6 opened on the top surface of the first mounting plate 1, and a plurality of split-line terminals 7 provided on the surface of the second mounting plate 2.

[0020] The mounting component 4 includes a connecting column 41, which is fixedly connected to the second mounting plate 2. It also includes a moving unit 42 and a fixing unit 43. The moving unit 42 is movably connected to both sides of the first mounting plate 1, and the fixing unit 43 is fixedly installed on both sides of the first mounting plate 1.

[0021] The surge protector 5 is a varistor module or a gas discharge tube module. Its input end is connected to the conductive copper busbar 3, and its output end is grounded. The branch terminal 7 is a screw terminal, both electrically connected to the conductive copper busbar 3. The conductive copper busbar 3 is the basic platform for the entire electrical connection. Any overvoltage appearing on the conductive copper busbar 3, such as a lightning-induced surge, can be quickly guided to the surge protector 5. When the surge protector 5 detects an overvoltage, it will instantly conduct, discharging the huge surge current to the ground through the ground wire, thereby protecting the downstream equipment. The branch terminal 7 is electrically connected to the conductive copper busbar 3. The cables of the external lines that need protection are crimped onto the branch terminal 7 and connected in parallel to the conductive copper busbar 3 through the branch terminal 7. The upper wire passes through the mounting hole 6 and connects to the branch terminal 7 so that the lightning current can be smoothly transmitted to the grounding system below, and finally safely conducted to the ground to prevent damage to the equipment.

[0022] like Figure 3 , Figure 4 and Figure 5 As shown, the moving unit 42 includes a moving block 421. A horizontally arranged first spring 422 is fixedly installed between the moving block 421 and the first mounting plate 1. A moving rod 423 is fixedly installed on one side of the moving block 421. A limit block 424 is movably connected to the lower end of the moving rod 423. A tension spring 425 is fixedly installed between the limit block 424 and the moving rod 423. The limit block 424 is inserted into the space below the moving rod 423, and then the two are connected by the tension spring 425. The fixing unit 43 includes a fixing plate 431. A second spring 432 is fixedly installed between the fixing plate 431 and the first mounting plate 1. The fixing plate 431 can move up and down in the space within the first mounting plate 1 by the second spring 432. The side of the moving rod 423 near the fixing plate 431 is set as an arc surface, such as... Figure 5 As shown above the right side of the moving rod 423, the end of the fixing plate 431 near the moving rod 423 is set with an arc surface, as shown below. Figure 5 As shown on the upper left side of the fixed plate 431, the moving rod 423 and the fixed plate 431 are in contact and connected.

[0023] When installing the branch line surge protection base, the first mounting plate 1 is fixed to the surge protection cabinet. If the surge protection base malfunctions and needs to be disassembled, the moving unit 42 is pulled to release the moving unit 42 from the second mounting plate 2. Then, the moving unit 42 is moved, and the moving rod 423 abuts against the fixed plate 431, causing the fixed plate 431 to move downward. When the fixed unit 43 is in the installation state, it cooperates with the moving unit 42 to form a snap-fit, so that the first mounting plate 1 and the second mounting plate 2 form a sealed state. The bottom edge of the first mounting plate 1 is provided with an annular sealing ring. When the second mounting plate 2 is closed with the first mounting plate 1, the sealing ring is compressed to form a seal, which prevents rainwater from falling into the first mounting plate 1 during rain and causing long-term corrosion of the first mounting plate 1 and the second mounting plate 2. This ensures that the electrical connection between all branch line terminals 7 and surge protection connectors 5 is stable and reliable, reducing contact resistance and fault risk. This utility model uses a movable unit 42 to release the movable unit 42 from the connecting post 41. After the movable unit 42 is released from the connecting post 41, the second mounting plate 2 is moved, so that the first mounting plate 1 and the second mounting plate 2 are separated, thereby quickly disassembling the second mounting plate 2.

[0024] With the cooperation of the moving unit 42 and the fixed unit 43, when the branch line surge protection base needs to be disassembled, the limiting block 424 is pulled to overcome the force of the tension spring 425, so that the limiting block 424 is released from the limiting groove of the second mounting plate 2. Then, the moving rod 423 is grasped and pulled to both sides, and the moving block 421 is released from the connecting column 41, thereby quickly separating the first mounting plate 1 and the second mounting plate 2. The second mounting plate 2 can be repaired quickly, avoiding the need to spend a lot of time when disassembling and repairing the branch line surge protection base. After maintenance, the first mounting plate 1 and the second mounting plate 2 are joined together. The first spring 422 drives the moving block 421 to reset, and the tension spring 425 drives the limiting block 424 to reset, so that the limiting block 424 engages with the limiting groove. When the moving rod 423 moves to the end of the first mounting plate 1, the second spring 432 drives the fixing plate 431 to reset, so that the first mounting plate 1 forms a sealed environment, preventing rainwater from dripping into the first mounting plate 1 and the second mounting plate 2 in rainy weather and causing corrosion to the lightning protection base. At the same time, the tension spring 425 drives the limiting block 424 to reset, so that the limiting block 424 engages with the second mounting plate 2, thereby fixing the first mounting plate 1 and the second mounting plate 2. The arc design of the moving rod 423 and the fixing plate 431 makes it easier for the moving rod 423 to resist the fixing plate 431 when moving.

[0025] like Figure 3 , Figure 4 and Figure 5As shown, the second mounting plate 2 has limit grooves on both sides, the limit block 424 is movably connected to the limit groove, the upper end of the connecting column 41 has grooves on both sides, the moving block 421 is movably connected to the groove, the moving rod 423 is movably connected to the first mounting plate 1, the first mounting plate 1 and the second mounting plate 2 are both made of stainless steel, and the moving rod 423 has a handle on the outside.

[0026] The movable rod 423 is movably connected to the first mounting plate 1, making the movable rod 423 more stable when moving the movable block 421. The stainless steel material does not contain harmful substances and has good chemical stability, reducing the risk of harmful substance pollution caused by metal corrosion. The surface is smooth and hard, and it is not easy to get stains when cleaning, making it very convenient to clean. It has high mechanical strength and durability and a long service life. The handle design of the movable rod 423 makes it more convenient to disassemble and maintain the second mounting plate 2 at the bottom when moving the movable rod 423.

[0027] The various embodiments in this specification are described in a related manner. For the same or similar parts between the various embodiments, please refer to each other. Each embodiment focuses on describing the differences from other embodiments.
