Description

Technical Field

[0001] This invention relates to the field of electromagnetic lock technology, and in particular to a grounding electromagnetic lock based on aviation plug integration technology. Background Technology

[0002] The grounding electromagnetic lock is a widely used grounding interlocking device in substations. During operation, the operator inserts the ground wire end into the grounding electromagnetic lock to ground the maintenance equipment or line, thereby ensuring the personal safety of the operator.

[0003] The existing electromagnetic locks are cumbersome to repair and replace, and cannot be replaced by maintenance personnel. The repair and replacement process is time-consuming. During the repair, screws are removed and the outer shell is opened with a screwdriver. After the repair is completed, the screws are fixed. Due to the large number of screws and the necessity of using a screwdriver, the entire disassembly and assembly process is cumbersome and time-consuming. The components of the existing electromagnetic locks are not modular, so the repair time is long. In addition, there are many types of grounding rods, and the existing electromagnetic locks cannot install grounding rods of different specifications.

[0004] To address the above shortcomings, a grounding electromagnetic lock is designed to enable rapid maintenance and replacement of the electromagnetic lock, thus shortening the replacement time. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of cumbersome maintenance and replacement of existing electromagnetic lock bodies, which cannot be completed by the maintenance personnel and require a long maintenance and replacement time. Therefore, this invention proposes a grounding electromagnetic lock based on aviation plug integration technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a grounding electromagnetic lock based on aviation plug integration technology, comprising an electromagnetic lock body, the electromagnetic lock body comprising a base plate, a housing, and a disassembly and assembly mechanism, the disassembly and assembly mechanism being disposed at the four corners of the base plate and the housing, a mounting plate being disposed at the bottom of the base plate, a through groove being provided on the surface of the mounting plate, a grounding rod being disposed on the electromagnetic lock body and the grounding rod being inserted into the through groove, a connecting mechanism being disposed at the bottom of the mounting plate, the connecting mechanism being used to install grounding rods of different diameters, and the base plate and the housing being connected through the disassembly and assembly mechanism.

[0007] Preferably, the bottom of the electromagnetic lock body is provided with an interface, and an aviation plug is inserted into the interface.

[0008] Preferably, the connecting mechanism includes a miniature cylinder fixed to the bottom of the mounting plate. Two rods are rotatably connected to the bottom of the mounting plate via a rotating shaft. A connecting plate is fixed to the output end of the miniature cylinder. Both ends of the connecting plate are rotatably connected to the two rods. A first arc-shaped clamping plate is fixed to one end of each of the two rods. The through groove is located inside the two first arc-shaped clamping plates.

[0009] Preferably, the disassembly and assembly mechanism includes a first connecting part and a second connecting part. The first connecting part is installed on the housing, and the second connecting part is fixed to the base plate. The housing and the base plate are connected through the first connecting part and the second connecting part.

[0010] Preferably, the first connecting portion includes a cylinder fixed to the bottom of the housing, the cylinder having a circular groove on its outer side, and a conical head connected to the other end of the cylinder via a vertical shaft. The diameter of the vertical shaft is smaller than the diameter of the cylinder and the conical head, so that the peripheral area of ​​the vertical shaft forms a slot.

[0011] Preferably, the second connecting portion includes a hollow column disposed on the base plate, the bottom of the hollow column extending out of the base plate, a first electromagnet fixed to the bottom of the hollow column, an iron sliding sleeve slidably connected to the outside of the hollow column, the sliding sleeve including an extrusion layer and a hollow groove, a convex ring fixed to the outer periphery of the bottom of the hollow column, a first spring disposed on the outside of the hollow column, the first spring being located between the sliding sleeve and the convex ring, and a conical groove disposed at the bottom of the hollow column; The hollow column is evenly distributed with limiting grooves, and a spherical locking block is provided inside the limiting groove. The locking block is used to cooperate with the circular groove.

[0012] Preferably, the limiting groove is wider on the side closer to the extrusion layer and narrower on the side farther from the extrusion layer, and the narrowest part of the limiting groove is smaller than the diameter of the card block.

[0013] Preferably, the hollow column has an iron insert inside, the insert is deformable and connected to each other to form a whole, and a second electromagnet is provided at the bottom of the hollow column; when the second electromagnet is energized, the insert moves closer to the side of the second electromagnet, and when the second electromagnet is de-energized, the insert returns to its original position in the slot.

[0014] Preferably, when the first electromagnet and the second electromagnet are energized simultaneously, the first connecting portion can be inserted into the second connecting portion; when the first electromagnet and the second electromagnet are de-energized, the first connecting portion is connected to the second connecting portion.

[0016] The beneficial effects of this invention are as follows: 1. The first and second connecting parts cooperate with each other to connect the housing and the base plate, which facilitates disassembly and maintenance. Specifically, when the electromagnetic lock body needs to be disassembled and maintained, the first electromagnet and the second electromagnet are energized again, the locking block leaves the slot, and then the base plate can be separated from the housing. This facilitates the disassembly and installation of the electromagnetic lock body by de-energizing and energizing the first and second electromagnets. The whole process takes very little time.

[0017] 2. The connecting plate moves as the output end of the miniature cylinder extends, and then the two rods rotate in opposite directions, causing the two arc-shaped clamps to move in opposite directions. The arc-shaped clamps help to clamp grounding rods of different diameters to accommodate grounding rods of different diameters. In addition, the electromagnetic lock body is equipped with a voice prompt function, which can provide voice prompts on the status of the switch nodes, facilitating fault repair.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0022] like Figures 1 to 3As shown, an embodiment of the present invention discloses a grounding electromagnetic lock based on aviation plug integration technology, comprising an electromagnetic lock body 1. The electromagnetic lock body 1 includes a base plate 2, a housing 3, and a disassembly / assembly mechanism 9. The disassembly / assembly mechanism 9 is disposed at the four corners of the base plate 2 and the housing 3. A mounting plate 4 is disposed at the bottom of the base plate 2, and a through groove 5 is provided on the surface of the mounting plate 4. A grounding rod 6 is disposed on the electromagnetic lock body 1, and the grounding rod 6 is inserted into the through groove 5. A connecting mechanism 7 is disposed at the bottom of the mounting plate 4. The connecting mechanism 7 is used to install grounding rods 6 of different diameters. Figure 5 As shown, the base plate 2 and the housing 3 are connected by the disassembly and assembly mechanism 9. The base plate 2 and the housing 3 can be quickly disassembled and assembled without the use of screws through the disassembly and assembly mechanism 9, which shortens the maintenance and replacement time of the electromagnetic lock body 1.

[0023] like Figure 10 As shown, the bottom of the electromagnetic lock body 1 is provided with an interface 8, and an aviation plug 11 is inserted into the interface 8. The wires entering the electromagnetic lock body 1 are first connected to the aviation plug 11, and then the aviation plug 11 is inserted into the interface 8. The aviation plug 11 is used to arrange and combine messy wires to achieve orderly access, which facilitates subsequent maintenance and replacement.

[0024] Furthermore, such as Figure 4 , Figure 7 and Figure 9 As shown, the connecting mechanism 7 includes a miniature cylinder 71 fixed to the bottom of the mounting plate 4. Two rods 73 are rotatably connected to the bottom of the mounting plate 4 via a rotating shaft 72. A connecting plate 74 is fixed to the output end of the miniature cylinder 71. Both ends of the connecting plate 74 are rotatably connected to the two rods 73. A first arc-shaped clamping plate 75 is fixed to one end of each of the two rods 73. A through groove 5 is located inside the two first arc-shaped clamping plates 75. It should be noted that the grounding rod 6 is installed inside the electromagnetic lock body 1. The output end of the miniature cylinder 71 extends, moving the connecting plate 74. Then, the two rods 73 rotate in opposite directions, causing the two first arc-shaped clamping plates 75 to move in opposite directions. The first arc-shaped clamping plates 75 facilitate clamping grounding rods 6 of different diameters to accommodate different diameter specifications. Furthermore, the electromagnetic lock body 1 has a voice prompt function, which can provide voice prompts about the status of the switching nodes, facilitating fault repair. A waterproof cover is provided outside the miniature cylinder 71 to protect it.

[0025] The disassembly and assembly mechanism 9 includes a first connecting part and a second connecting part. The first connecting part is installed on the housing 3, and the second connecting part is fixed on the base plate 2. The housing 3 and the base plate 2 are connected through the first connecting part and the second connecting part.

[0026] The housing 3 is connected to the base plate 2 by the first connecting part and the second connecting part.

[0027] Specifically, refer to Figure 5 and Figure 6The first connecting part includes a cylinder 901 fixed to the bottom of the housing 3. A circular groove 902 is provided on the outside of the cylinder 901. The other end of the cylinder 901 is connected to a conical head 904 through a vertical shaft 903. The diameter of the vertical shaft 903 is smaller than the diameter of the cylinder 901 and the conical head 904, so that the peripheral area of ​​the vertical shaft 903 forms a slot 905.

[0028] The second connecting part includes a hollow column 906 disposed on the base plate 2, the bottom of the hollow column 906 extending out of the base plate 2, a first electromagnet 907 fixed at the bottom of the hollow column 906, an iron sliding sleeve 908 slidably connected to the outside of the hollow column 906, the sliding sleeve 908 including an extrusion layer 909 and a hollow groove 910, a protruding ring 911 fixed on the outer periphery of the bottom of the hollow column 906, a first spring 912 disposed on the outside of the hollow column 906, the first spring 912 being located between the sliding sleeve 908 and the protruding ring 911, and a tapered groove 913 disposed at the bottom of the hollow column 906; Hollow column 906 has evenly distributed limiting grooves 914, and the inside of the limiting groove 914 is provided with a spherical locking block 915, which is used to cooperate with the circular groove 902.

[0029] The limiting groove 914 is wider on the side closer to the extrusion layer 909 and narrower on the side farther from the extrusion layer 909. The narrowest point of the limiting groove 914 is smaller than the diameter of the locking block 915. This prevents the locking block 915 from falling out of the limiting groove 914.

[0030] The hollow column 906 contains an iron insert 916, which is deformable and interconnected to form a single unit. A second electromagnet 917 is located at the bottom of the hollow column 906. When the second electromagnet 917 is energized, the insert 916 moves closer to the side of the second electromagnet 917. When the second electromagnet 917 is de-energized, the insert 916 returns to its original position and enters the slot 905. When the first electromagnet 907 and the second electromagnet 917 are simultaneously energized, the first connecting part can be inserted into the second connecting part. When the first electromagnet 907 and the second electromagnet 917 are de-energized, the first connecting part and the second connecting part are connected.

[0031] Optionally, the housing 3 of the electromagnetic lock body 1 is provided with a separate button for controlling the first electromagnet 907 and the second electromagnet 917, which is separate from the indicator button and the operation button.

[0032] It should be noted that when the button on the electromagnetic lock body 1 is pressed, the first electromagnet 907 and the second electromagnet 917 are energized. When the first electromagnet 907 is energized, it attracts the iron sliding sleeve 908 through strong magnetic force. Then, the sliding sleeve 908 descends outside the hollow column 906 and compresses the first spring 912. When the sliding sleeve 908 descends, the inner pressing layer 909 moves away from the position of the locking block 915, and the hollow groove 910 moves to the position of the locking block 915. Then, the pressing layer 909 presses against the locking block 915. When the pressure disappears, the locking block 915 can move between the limiting groove 914 and the hollow groove 910. The limiting groove 914 is wider on the side closer to the extrusion layer 909 and narrower on the side farther from the extrusion layer 909. The narrowest point of the limiting groove 914 is larger than the diameter of the locking block 915 to prevent the locking block 915 from falling out of the limiting groove 914. After the second electromagnet 917 is energized, it attracts the insertion block 916. Then the insertion block 916 deforms and moves closer to the inner wall of the hollow column 906. After that, the cylinder 901 at the bottom of the housing 3... The cone head 904 is inserted into the hollow column 906, then moves into the conical groove 913, and the circular groove 902 is positioned exactly at the stop block 915. Then, the first electromagnet 907 and the second electromagnet 917 are de-energized. After the first electromagnet 907 is de-energized, its attraction to the sliding sleeve 908 disappears. Then, the first spring 912 resets, causing the sliding sleeve 908 to rise. Afterward, the pressing layer 909 rises and re-presses the stop block 915, forcing it into the circular groove 902. The second electromagnet... After the iron 917 is de-energized, the insert 916 returns to its original shape, and then multiple inserts 916 enter the interior of the slot 905. This facilitates the use of the locking block 915 and the inserts 916 to firmly fix the cylinder 901 inside the hollow column 906, thereby fixing the housing 3 to the top of the base plate 2. When the electromagnetic lock body 1 needs to be disassembled for maintenance, the first electromagnet 907 and the second electromagnet 917 are energized again, and the inserts 916 leave the slot 905. Then the base plate 2 and the housing 3 can be separated.

[0033] like Figure 8 As shown, a second spring 12 is fixed to the inner side of the through groove 5, and a second arc-shaped clamp 13 is fixed to one end of the second spring 12. A micro switch 14 is provided on the inner side of the second arc-shaped clamp 13. The second spring 12 allows the second arc-shaped clamp 13 to adapt to grounding rods 6 of different diameters. Due to the rebound force of the second spring 12, grounding rods 6 of different diameters can fit against the second arc-shaped clamp 13, thereby allowing grounding rods 6 of different diameters to contact the micro switch 14. Then, the installed grounding rods 6 are fixed by clamping with the micro cylinder 71.

[0034] The electromagnetic lock body 1 has four internal modules: a shell structure module, a logic locking module, a manual unlocking module, and a power supply module. This modular design allows for easy replacement and assembly, saving maintenance time. The shell structure features a dual-compartment design, isolating the lock body from the power supply side, protecting internal components, and reducing humidity. The logic locking, mechanical unlocking, status indicator lights, and operation buttons are located in one compartment, while the aviation connector terminals and voltage reduction module are in another. Waterproof strips and internal drainage channels are added to the gap between the lock body compartment and the power supply compartment, and waterproof gaskets are added to the grounding wire holes. This design prevents water droplets and condensation in the lock body and power supply compartments. The logic locking module uses relays, which are low-cost, have a long service life, reliable contact output, and fast response. All logic locking is achieved through relays, with a small number of mechanical switches introducing multiple contacts. The manual unlocking module includes a voltage reduction module, a protection module, and an operation module. The voltage reduction module converts 220V AC to 12V DC, reducing the risk of electric shock and increasing module replacement speed to 6 seconds. For speeds below 0s, the step-down module uses a plug-in design, connecting the power input line, status indicator light, and operation button connection lines to the circuit board via connectors. This results in short replacement time, output ripple of less than 100mV, short-circuit response time, excellent waterproof performance, and long service life. Specifically, the plug-in design is encapsulated with potting compound to meet selection requirements. The protection module protects the wiring within the lock body, preventing mechanical wear and tear on the wiring insulation. The protection module uses a metal baffle for isolation, with a metal isolation baffle installed above the coil drive plate. Indicator light connection lines, button connection lines, and coil connection lines are bundled with cable ties to fully isolate the connection lines from the drive plate. With the metal isolation baffle installed, the drive plate scratch rate is 0%, and its lifespan is long. The operation module facilitates the replacement of frequently damaged parts, reducing maintenance costs. The operation module uses a split installation design for long service life. The power supply module can be hot-swapped in as little as 10 seconds, allowing for rapid connection and disconnection from the equipment, reducing the short-circuit failure rate during wiring. It uses a screw-lock aviation plug, ensuring high reliability and short manufacturing time.

[0035] Working principle: Through the disassembly and assembly mechanism 9, the first electromagnet 907 and the second electromagnet 917 are energized by the button on the electromagnetic lock body 1. When the first electromagnet 907 is energized, it attracts the iron sliding sleeve 908 through strong magnetic force. Then, the sliding sleeve 908 descends outside the hollow column 906 and compresses the first spring 912. When the sliding sleeve 908 descends, the inner pressing layer 909 moves away from the position of the locking block 915, and the hollow groove 910 moves to the position of the locking block 915. Then, the pressure of the pressing layer 909 on the locking block 915 disappears. At this time, the locking block 915 can move between the limiting groove 914 and the hollow groove 910. The limiting groove 914 is wider on the side closer to the pressing layer 909 and narrower on the side farther away from the pressing layer 909. The narrowest part is larger than the diameter of the locking block 915 to prevent the locking block 915 from falling out of the limiting groove 914. After the second electromagnet 917 is energized, it attracts the insert block 916. Then the insert block 916 deforms and moves closer to the inner wall of the hollow column 906. Then the cylinder 901 at the bottom of the housing 3 is inserted into the hollow column 906. Then the conical head 904 moves into the inside of the conical groove 913, and the circular groove 902 is exactly at the position of the locking block 915. Then the first electromagnet 907 and the second electromagnet 917 are de-energized. After the first electromagnet 907 is de-energized, the attraction force on the sliding sleeve 908 disappears. Then the first spring 912 returns to its original position and drives the sliding sleeve 908 to rise. Then the pressing layer 909 rises and presses the locking block 915 again, forcing the locking block 915 into the inside of the circular groove 902. After the second electromagnet 917 is de-energized, the insertion block 916 returns to its original shape, and then multiple insertion blocks 916 enter the interior of the slot 905. This facilitates the use of the locking block 915 and the insertion blocks 916 to firmly fix the cylinder 901 inside the hollow column 906, thereby fixing the housing 3 to the top of the base plate 2. When the electromagnetic lock body 1 needs to be disassembled for maintenance, the first electromagnet 907 and the second electromagnet 917 are energized again, and the insertion blocks 916 leave the slot 905. Then the base plate 2 can be separated from the housing 3. This facilitates the disassembly and installation of the electromagnetic lock body 1 by de-energizing and energizing the first electromagnet 907 and the second electromagnet 917. The whole process is very short, which is beneficial for solving the problem of removing screws and opening the outer shell with a screwdriver during the current maintenance process. The problem of tedious and time-consuming disassembly and assembly due to the large number of screws and the need for screwdrivers, which requires screwdrivers, is addressed by the connecting mechanism 7. The grounding rod 6 is installed inside the electromagnetic lock body 1. The output end of the miniature cylinder 71 extends, moving the connecting plate 74. Then, the two rods 73 rotate in opposite directions, causing the two first arc-shaped clamping plates 75 to move in opposite directions. The first arc-shaped clamping plates 75 facilitate clamping grounding rods of different diameters to accommodate different specifications. Furthermore, the electromagnetic lock body 1 has a voice prompt function, providing voice indication of the status of the switching nodes for convenient troubleshooting. The electromagnetic lock body 1 contains four modules: a shell structure module, a logic locking module, a manual unlocking module, and a power supply module.Modular design allows for easy replacement and assembly of modules, saving maintenance time for the electromagnetic lock body 1. The outer shell structure adopts a dual-chamber design, which isolates the lock body side from the power supply side, protecting internal components and reducing humidity inside the chamber. The logic locking, mechanical unlocking, status indicator lights, and operation buttons are located in one chamber, while the aviation plug terminals and the step-down module are located in another chamber. Waterproof strips and internal drainage channels are added to the gap between the lock body chamber and the power supply chamber of the electromagnetic lock body 1, and waterproof gaskets are added to the grounding wire holes. This design ensures that there are no water droplets or condensation in the lock body chamber and the power supply chamber. The logic locking module adopts a relay type, which has low manufacturing cost, long service life, reliable contact output, and fast response. All logic locking is implemented through relays, and a large number of contacts are introduced through a small number of mechanical switches. The manual unlocking module includes a step-down module, a protection module, and an operation module. The step-down module converts 220V AC power to 12V DC power, reducing the risk of electric shock to personnel and improving the module replacement speed to less than 60 seconds. The step-down module adopts a plug-in type, connecting the power input line, status indicator lights, and operation button connection lines through connectors and electrical... The circuit board is connected, requiring short replacement time. The plug-in output ripple is less than 100mV, the module load short-circuit response time is short, it has excellent waterproof performance, and a long service life. The plug-in type is specifically encapsulated, with overall potting compound treatment to meet the selection criteria. The protection module can protect the wiring inside the lock body, preventing mechanical movement from wearing the wiring insulation. The protection module uses a metal baffle for isolation. A metal isolation baffle is installed above the coil drive plate. The indicator light connection wires, button connection wires, and coil connection wires are bundled with cable ties to fully isolate the connection wires from the drive plate. After adding the metal isolation baffle, the wear rate of the drive plate is 0, and the lifespan is long. The operation module facilitates the replacement of frequently damaged parts and reduces maintenance costs. The operation module adopts a split installation and has a long service life. The power supply module can achieve hot-swapping with a time of less than 10 seconds, quickly connecting and disconnecting from the equipment, reducing the short-circuit fault rate during wiring. It uses a screw-lock aviation plug, which has high reliability and short manufacturing time. The modular design achieves replaceability and easy assembly, greatly saving maintenance time, and the cumbersome replacement can be completed by the maintenance personnel themselves.
