Description

Technical Field

[0002] Industrial smart gateways are core devices in the Industrial Internet of Things (IIoT), primarily used to connect industrial field devices, sensors, controllers, and cloud platforms or upper-level management systems. They enable functions such as data acquisition, protocol conversion, edge computing, and remote control. A typical industrial smart gateway consists of a core processing module, a communication interface module, a protocol conversion and edge computing module, a storage module, a security encryption module, a power and consumption management module, and a housing and industrial protection module. The relationship between the industrial smart gateway and the fan equipment in a thermal power plant can be summarized as "collaborative linkage between a data hub and field devices." As a bridge connecting the physical and digital worlds, the industrial gateway acquires, converts, and intelligently processes data from the fan equipment, enabling real-time monitoring of the fan's operating status, fault warnings, and optimized control. During use, the thermal power plant fan equipment needs to be connected to the industrial smart gateway via a wiring connection device.

[0003] However, when using the existing wiring connection device for thermal power plant fan equipment, the cover of the terminal box needs to be opened when connecting the cable to the terminal block, which is not convenient and quick. At the same time, external dust, water stains and other impurities can easily enter the interior, affecting the wiring connection effect and service life.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-14 The diagram illustrates a wiring connection device for a thermal power plant fan, used to connect the fan unit 1 to an industrial intelligent gateway 30. It includes a terminal box 101 mounted on the fan unit 1. The industrial intelligent gateway 30 mainly consists of a core processing module, a communication interface module, a protocol conversion and edge computing module, a storage module, a security encryption module, a power and consumption management module, and a housing and industrial protection module. It can realize functions such as data acquisition, protocol conversion, edge computing, and remote control, achieving real-time monitoring, fault warning, and optimized control of the fan's operating status. This is a well-known technology in this field and will not be elaborated upon here. The top of the terminal box 101 is detachably connected to a cover 102. A terminal block 103 is provided inside the terminal box 101, and the terminal block 103 has multiple terminal holes 104. It also includes: Multiple mounting boxes 19 are fixed to the side wall of the terminal box 101 and communicate with the interior of the terminal box 101 through through holes 15; Multiple sealing caps 18 are disposed inside the terminal box 101 and are rotatably connected to the inner wall of the terminal box 101 via a torque shaft assembly 17. They can seal the through hole 15. The torque shaft assembly 17 can make the sealing caps 18 automatically reset. Its structure and principle are well known in the field of this technology and will not be described in detail here. Multiple crimping mechanisms are provided on the top of the cover 102 for crimping the wire cores inserted into the terminal holes 104; The cable feeding mechanism, located within each mounting box 19, is used to feed the cable into the terminal hole 104. During wiring connection, there is no need to disassemble the box cover 102, making it more convenient and faster. At the same time, it can ensure the sealing effect inside the terminal box 101, preventing the entry of dust, water stains and other impurities, ensuring the wiring connection effect and service life. Furthermore, it can perform a clamping operation on the wire core, increasing the pressure between the extrusion plate 14 and the wire core, making it more stable and reliable. The cable can be a single strand of solid wire.

[0021] The crimping mechanism includes a lifting plate 13, and a first sleeve 202 is fixedly connected to the top of the lifting plate 13. A first sleeve rod 201 is inserted into the first sleeve 202, and the upper end of the first sleeve rod 201 is fixed to the top of the cover 102. A threaded tube 203 is fixedly connected to the top of the lifting plate 13, and a threaded rod 204 is threadedly connected inside the threaded tube 203. The upper end of the threaded rod 204 is rotatably connected to the top of the cover 102, and a rocker wheel 205 is fixedly connected to the upper end of the threaded rod 204. A pressing plate 14 is connected to the bottom of the lifting plate 13 through a pre-tightening mechanism. Rotating the rocker wheel 205 causes the threaded rod 204 to rotate. When the threaded rod 204 rotates, it can drive the lifting plate 13 to move downward. At the same time, the pressing plate 14 is driven to move downward through the pre-tightening mechanism. When the pressing plate 14 abuts against the wire core, it can perform a pressing operation on the wire core.

[0022] The pre-tightening mechanism includes two symmetrically arranged second sleeve rods 301 fixedly connected to the bottom of the lifting plate 13. Each second sleeve rod 301 has a second sleeve 302 sleeved on its side wall. The lower end of the second sleeve 302 is fixed to the top of the extrusion plate 14. Each second sleeve 302 has a first spring 303 sleeved on its side wall. When the extrusion plate 14 abuts against the wire core, it can perform a pressing operation on the wire core. At the same time, the first spring 303 is gradually compressed, increasing the pressure between the extrusion plate 14 and the wire core, making it more stable and reliable.

[0023] The wire feeding mechanism includes a slot 29 on the top of the mounting box 19, and a cover plate 10 is rotatably connected to the slot 29 via a rotating shaft 9. A first moving block 20 is connected to the mounting box 19 via a first moving mechanism. A U-shaped groove 21 is formed on the side wall of the first moving block 20. Two symmetrically arranged rubber blocks 22 are fixedly connected to the opposite side walls of the U-shaped groove 21. Two symmetrically arranged second moving blocks 23 are connected to the side walls of the first moving block 20 via a telescopic mechanism. Two symmetrically arranged third moving blocks 24 are connected to the side walls of each second moving block 23 via a second moving mechanism. Semicircular tubes 25 are fixedly connected to the opposite side walls of the two third moving blocks 24. A telescopic cover 26 is fixedly connected between the second moving blocks 23 and the third moving blocks 24. When the threaded rod 2... When 04 rotates, the first moving mechanism drives the first moving block 20 to move closer to the terminal box 101. At the same time, the telescopic mechanism drives the second moving block 23 and the semi-circular tube 25 to move, thereby driving the cable to move synchronously. After the semi-circular tube 25 passes through the through hole 15, it abuts against the sealing cover 18, thereby pushing the sealing cover 18 to rotate upward and open. At the same time, the semi-circular tube 25 moves into the through hole 15 and forms a seal under the action of the sealing ring 16. When the second moving block 23 abuts against the side wall of the terminal box 101, the second moving block 23 stops moving. When the first moving block 20 continues to move, it can drive the cable to continue to be transported along the semi-circular tube 25, thereby extending the wire core from the semi-circular tube 25 and moving it into the terminal hole 104.

[0024] The first moving mechanism includes a sliding groove 501 formed in the inner wall of the mounting box 19, and a sliding plate 502 slidably connected in the sliding groove 501. Two symmetrically arranged second springs 503 are fixedly connected between the bottom of the sliding plate 502 and the sliding groove 501. A first push pin 505 is fixedly connected to the top of the sliding plate 502, and the upper end of the first push pin 505 penetrates the top of the mounting box 19. A first inclined groove 504 is formed in the side wall of the sliding plate 502. A second push pin 506 is fixedly connected to the side wall of the first moving block 20, and the second push pin 506 is inserted into the first inclined groove 504. An L-shaped plate 509 is connected to the top of the box cover 102 through a moving component, and a sliding block 510 is fixedly connected to the lower end of the L-shaped plate 509. The sliding block 510 slides on the top of the mounting box 19, and the side wall of the sliding block 510 is fixedly connected to the mounting plate 507. The side wall of the mounting plate 507 is fixedly connected to the inclined plate 508, and the upper end of the first push pin 505 can slide on the inclined plate 508. When the sliding block 510 slides to the top of the cover plate 10, it pushes the cover plate 10 to rotate downward along the rotating shaft 9 to close it. At the same time, it will abut against the upper end of the fourth push pin 706, thereby pushing the slider 703 to slide downward along the guide rail 704. When the slider 703 moves downward, it causes the third push pin 702 to move upward along the second inclined groove 705. At this time, it can push the two third moving blocks 24 to move closer to each other, so that the two semi-circular tubes 25 wrap the cable and form a whole tube.

[0025] The movable component includes a fixing block 601 fixedly connected to the top of the cover 102, and two symmetrically arranged T-shaped guide rods 602 are inserted into the side wall of the fixing block 601. One end of the T-shaped guide rod 602 is fixedly connected to a connecting block 603, and the connecting block 603 is fixed to the side wall of the L-shaped plate 509. A rack 605 is fixedly connected to the side wall of the connecting block 603. A gear 604 is fixedly sleeved on the side wall of the threaded rod 204, and the gear 604 meshes with the rack 605. When the rocker wheel 205 is rotated, the rotation of the rocker wheel 205 drives the rotation of the threaded rod 204 and the gear 604, thereby driving the rack 605 to move. When the rack 605 moves, it can drive the connecting block 603 and the T-shaped guide rod 602 to move, and then drive the sliding block 510 to move through the L-shaped plate 509.

[0026] The second moving mechanism includes a guide rail 704 fixedly connected to the side wall of the second moving block 23, and a slider 703 slidably connected to the side wall of the guide rail 704. The side wall of the slider 703 is provided with a second inclined groove 705. The side wall of the third moving block 24 is fixedly connected to a support block 701. The side wall of the support block 701 is fixedly connected to a third push pin 702, and the third push pin 702 is inserted into the second inclined groove 705. A reset mechanism is provided between the third moving block 24 and the second moving block 23. The top of the slider 703 is fixedly connected to a fourth push pin 706, and the upper end of the fourth push pin 706 passes through the top of the telescopic cover 26. When the cover plate 10 rotates downward along the rotating shaft 9 to close, it will abut against the upper end of the fourth push pin 706, thereby pushing the slider 703 to slide downward along the guide rail 704. When the slider 703 moves downward, the third push pin 702 moves upward along the second inclined groove 705. At this time, it can push the two third moving blocks 24 to move closer to each other.

[0027] The reset mechanism includes two symmetrically arranged third sleeve rods 802 fixedly connected to the side wall of each third moving block 24, and a third sleeve 801 is sleeved on the side wall of each third sleeve rod 802. The other end of the third sleeve 801 is fixed to the side wall of the second moving block 23, and a third spring 803 is sleeved on the side wall of each third sleeve 801, which plays a guiding and reset role for the movement of the third moving block 24.

[0028] The telescopic mechanism includes two symmetrically arranged fourth sleeve rods 402 fixedly connected to the side wall of each second moving block 23, and a fourth sleeve 401 is sleeved on the side wall of each fourth sleeve rod 402. The other end of the fourth sleeve 401 is fixed to the side wall of the first moving block 20, and a fourth spring 403 is sleeved on the side wall of each fourth sleeve 401. When the second moving block 23 abuts against the side wall of the terminal box 101, the second moving block 23 stops moving. When the first moving block 20 continues to move, the fourth spring 403 is compressed.

[0029] An air outlet pipe 27 is fixedly inserted into the top of the mounting box 19, and a first one-way valve is installed inside the air outlet pipe 27. The conduction direction of the first one-way valve is from the inside of the mounting box 19 to the outside. An air inlet pipe 28 is fixedly inserted into the bottom of the mounting box 19, and a second one-way valve is installed inside the air inlet pipe 28. The conduction direction of the second one-way valve is from the outside to the inside of the mounting box 19. An air extraction valve 11 and an air inflation valve 12 are fixedly connected to the top of the box cover 102, and a sealing ring 16 is installed in the through hole 15. When the second moving block 23 moves towards the terminal box 101, it can compress the air inside the mounting box 19. Simultaneously, the first one-way valve opens and the second one-way valve closes, allowing internal air to be discharged through the vent pipe 27. When the second moving block 23 moves away from the terminal box 101, the first one-way valve closes and the second one-way valve opens, allowing external air to enter the mounting box 19, preventing negative pressure and ensuring the normal movement of the second moving block 23. The sealing ring 16 ensures the sealing performance after the semi-circular tube 25 is inserted. The air extraction valve 11 and the air filling valve 12 facilitate the discharge of air from the terminal box 101 and the supply of protective gas into the terminal box 101.

[0030] Working principle: When wiring is required, the cover plate 10 is rotated upward along the shaft 9 to open. When the cover plate 10 is disengaged from the upper end of the fourth push pin 706, the two third moving blocks 24 can move away from each other under the action of the third spring 803. At the same time, the third push pin 702 slides downward along the second inclined groove 705, pushing the slider 703 to move upward along the guide rail 704, and causing the fourth push pin 706 to move upward and extend. When the third moving block 24 moves, it can drive the two semi-circular tubes 25 to move away from each other. Then, the cable with the insulation stripped off the head is placed between the two semi-circular tubes 25. At the same time, the cable moves between the two rubber blocks 22 and is clamped.

[0031] Next, the rocker wheel 205 is rotated. The rotation of the rocker wheel 205 drives the rotation of the threaded rod 204 and the gear 604, thereby driving the rack 605 to move. When the rack 605 moves, it can drive the connecting block 603 and the T-shaped guide rod 602 to move, and then drive the sliding block 510 to move through the L-shaped plate 509. When the sliding block 510 slides to the top of the cover plate 10, it pushes the cover plate 10 to rotate downward along the rotating shaft 9 to close it. At the same time, it will abut against the upper end of the fourth push pin 706, thereby pushing the slider 703 to slide downward along the guide rail 704. When the slider 703 moves downward, it causes the third push pin 702 to move upward along the second inclined groove 705. At this time, it can push the two third moving blocks 24 to move closer to each other. At the same time, the third spring 803 is stretched, so that the two semi-circular tubes 25 wrap the cable and form a whole tube.

[0032] Furthermore, when the sliding block 510 moves, it can drive the mounting plate 507 and the inclined plate 508 to move, so that when the upper end of the first push pin 505 slides along the inclined plate 508 to the bottom of the mounting plate 507, it can push the fixed block 601 to move downward. At the same time, it drives the sliding plate 502 to slide downward along the sliding groove 501, the second spring 503 is compressed, and the second push pin 506 can slide upward along the first inclined groove 504, thereby pushing the first moving block 20 to move closer to the terminal box 101. At the same time, the telescopic mechanism drives the second moving block 23 and the semi-circular tube 25 to move, thereby driving the cable to move synchronously. After the semi-circular tube 25 passes through the through hole 15, it abuts against the sealing cover 18, thereby pushing the sealing cover 18 to rotate upward and open. At the same time, the semi-circular tube 25 moves into the through hole 15 and forms a seal under the action of the sealing ring 16.

[0033] When the second moving block 23 abuts against the side wall of the terminal box 101, the second moving block 23 stops moving. When the first moving block 20 continues to move, the fourth spring 403 is compressed. At the same time, it can drive the cable to continue to be transported along the semi-circular tube 25, thereby extending the wire core from the semi-circular tube 25 and moving it into the terminal hole 104. When the threaded rod 204 rotates, it can drive the lifting plate 13 to move downward. At the same time, it drives the pressing plate 14 to move downward through the pre-tightening mechanism. When the pressing plate 14 abuts against the wire core, it can perform a pressing operation on the wire core. At the same time, the first spring 303 is gradually compressed, increasing the pressure between the pressing plate 14 and the wire core, making it more stable and reliable. When it is necessary to disassemble the cable, the same principle applies: the rocker wheel 205 can be reversed. This makes it easier and faster to connect the wires without disassembling the box cover 102. At the same time, it can ensure the sealing effect inside the terminal box 101, preventing the entry of dust, water stains and other impurities, ensuring the effectiveness of the wiring connection and the service life.
