Description

Technical Field

[0001] This invention belongs to the field of measurement and control terminal technology, and specifically relates to a pulse-controlled dual-control terminal based on 4G communication. Background Technology

[0002] A 4G-based pulse-controlled power terminal typically refers to an intelligent power control device that utilizes a 4G network to achieve remote bidirectional control (dual control) and pulse signal triggering or metering functions. It is an integrated industrial IoT measurement and control terminal that integrates four core capabilities: 4G wireless communication, pulse signal acquisition, two independent power control outputs, and local and remote dual control. It can connect to the operator's cellular network without wiring, remotely acquire pulse metering data, and independently control two power circuits. This type of device solves the problems of high deployment costs and limited Wi-Fi coverage associated with traditional wired control systems, and is widely used in water conservancy wells, school dormitories, prepaid industrial parks, and industrial branch power distribution scenarios.

[0003] In existing technologies, existing pulse-controlled dual-control terminals typically have a rain shield installed on the top of the equipment box for rain protection. However, during use, the rain shield completely covers the top of the equipment box, making it difficult for heat to dissipate. The fully covered metal rain shield also forms an electromagnetic shielding layer, blocking the transmission and reception of electromagnetic waves from the 4G antenna. In areas with weak base station signals, such as fields and mountains, this causes a significant attenuation of the 4G signal, frequent terminal offline, loss of remote power control commands, and difficulty in ensuring stable communication of the equipment, which is not conducive to long-term reliable operation.

[0004] Therefore, it is necessary to invent a pulse-controlled dual-control terminal based on 4G communication to solve the above problems. Summary of the Invention

The bottom end of the push plate is hinged to the limiting block. The limiting block is movably connected to the inner wall of the fixed block. The limiting block is inserted into the limiting slot.

[0012] Furthermore, a protective mechanism is provided between the movable plate and the fixed block.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] This invention provides a pulse-controlled dual-control terminal based on 4G communication, such as... Figures 1 to 9 As shown, the device includes an equipment box 1, a through hole 2, and a rainproof mechanism. The equipment box 1 is used to house core electrical components such as a 4G communication module, relays, and a pulse acquisition board. The through hole 2 is located on the top of the equipment box 1 for heat dissipation and signal reception. The rainproof mechanism is located on both sides of the top of the equipment box 1 and includes a mounting block 3, a connector, a mounting groove 4, a first electric push rod 5, a fixing plate 6, and a fixing structure. The mounting block 3 is hinged to both ends of the top of the equipment box 1. A connector is installed inside the mounting block 3 to move the connector. The mounting groove 4 is located in the middle of the top of the equipment box and is fixedly connected to the first electric push rod 5. The top of the first electric push rod 5 is fixedly connected to the fixing plate 6. The fixing structure is located on both sides of the fixing plate 6 to fix the connector and the fixing plate 6. A fixing seat 7 is fixedly installed on the outside of the equipment box 1, and a fixing rod 8 is fixedly installed at the bottom of the fixing seat 7 for mounting and fixing the equipment box 1. This device is suitable for outdoor installation scenarios such as field wells and park power distribution. The through hole 2 is located between the mounting block 3 and the fixing plate 6. There are multiple through holes 2, which are arranged in a linear array to quickly dissipate the heat generated by the electrical components in the equipment box 1, reduce the temperature rise inside the box, and ensure the normal transmission and reception of the RF signal of the 4G antenna, avoiding signal attenuation due to blockage. The mounting block 3, connectors and fixing structure are arranged symmetrically with respect to the center of the equipment box 1.

[0021] When the terminal detects rainfall or needs to execute a rain protection command, the terminal control module triggers an action command. The protective structure moves into the fixed slot for storage, and the connecting piece moves to the fixed plate 6. The fixed structure connects the fixed block 13, the connecting piece, and the fixed block 13 into a whole structure. Then, the first electric push rod 5 in the mounting slot 4 extends upward along its output axis, driving the fixed plate 6, which is fixedly connected to its top, to move vertically upward along the mounting slot 4 to the preset rainproof height. Subsequently, the mounting blocks 3 hinged at both ends of the top of the equipment box 1 drive the connecting piece, the fixed structure, and the fixed plate 6 to deflect, so that the connecting pieces of the mounting blocks 3 on both sides and the fixed plate 6 in the middle are spliced ​​together to form a complete rainproof surface, which fully covers the top and bottom of the equipment box 1, effectively preventing rainwater and dew from seeping into the interior of the equipment box 1, preventing the core electrical components such as the internal 4G communication module and relays from being corroded or short-circuited, and ensuring the normal operation of the terminal. When rain protection is not required, the first electric push rod 5 moves the fixing plate 6 to its original position and is stored in the mounting slot 4. This allows the mounting block 3, connector, and fixing structure to move to the top of the equipment box 1. The fixing structure releases the locking of the connector and the fixing plate 6. Subsequently, the connector retracts and resets to the inside of the mounting block 3, and the two mounting blocks 3 on both sides reset to their initial positions around the hinge. At this time, the rainproof mechanism is completely stored in the mounting slots 4 at both ends and in the middle of the top of the equipment box 1. It does not block the multiple through holes 2 located between the mounting block 3 and the fixing plate 6 in a linear array. This ensures smooth heat dissipation inside the equipment box 1, allowing the heat generated by the electrical components to be discharged through the through holes 2, reducing the temperature rise inside the box, reducing the temperature difference between day and night, alleviating the problem of condensation and water accumulation, and extending the service life of the components. It also avoids the formation of electromagnetic shielding areas by metal parts, ensuring that the 4G antenna radio frequency signal can be transmitted and received normally through the through holes 2. This effectively solves the technical problems of signal attenuation, terminal offline, and loss of remote power control commands in weak signal areas such as fields and mountains.

[0022] like Figures 6 to 8 As shown, the connector includes a second electric push rod 9, a connecting plate 10, and a movable plate 11. The second electric push rod 9 is fixedly connected to the inner wall of the mounting block 3. The connecting plate 10 is movably connected inside the mounting block 3. A movable groove is provided on one side of the connecting plate 10. One end of the second electric push rod 9 is fixedly connected to the inner wall of the mounting block 3, and the other end is fixedly connected to the inner wall of the movable groove. A groove is provided at the end of the connecting plate 10, and the movable plate 11 is movably connected inside the groove. The second electric push rod 9 is located at both ends of the connecting plate 10. One end of the movable plate 11 extends through the connecting plate 10 to the outside of the mounting block 3. Both sides of the movable plate 11 located on the outside of the mounting block 3 are provided with limiting grooves 12. The limiting grooves 12 are adapted to the fixing structure to lock the movable plate 11 and the fixed plate 6, preventing loosening after docking and ensuring the structural stability of the rainproof surface.

[0023] The various components of the connector work in coordination with the mounting block 3 and the fixing plate 6, and are symmetrically arranged around the center of the equipment box 1 to ensure that the actions of the connectors on both sides are synchronized, ensuring the flatness and sealing of the rainproof surface splicing. When rain protection is required, the two second electric push rods 9 on the inner wall of the mounting block 3 are activated to push the connecting plate 10 along the inner wall of the mounting block 3 towards the fixing plate 6, until the movable plate 11 at the end of the connecting plate 10 corresponds to the fixing structure on both sides of the fixing plate 6, and the limiting grooves 12 on both sides of the movable plate 11 engage with the fixing structure. By locking the limiting grooves 12 through the fixing structure, the movable plate 11 and the fixing plate 6 can be detachably fixed. When an electric push rod 5 moves the fixed plate 6, the fixed plate 6, and the fixed structure upward, the mounting block 3, the connecting plate 10, and the movable plate 11 deflect. Since the connecting plate 10 is connected to the fixed structure through the movable plate 11, one end of the movable plate 11 moves out of the groove, increasing the length of the connecting plate 10, thereby adapting to the deflection of the overall structure. This facilitates the splicing of the connecting parts of the mounting blocks 3 on both sides with the fixed plate 6 in the middle to form a complete and sealed rainproof surface, which fully covers the top and bottom of the equipment box 1, effectively preventing rainwater and dew from seeping in, preventing corrosion and short circuits of internal core components such as 4G communication modules and relays, and ensuring the normal operation of the terminal.

[0024] like Figures 7 to 9 As shown, the fixing structure includes a fixing block 13, a limiting block 14, and a driving component. The fixing block 13 is hinged to both sides of the fixing plate 6. The fixing block 13 has a movable groove on the side near the through hole 2. The movable plate 11 is inserted into the movable groove to realize the detachable fixing of the movable plate 11 and the fixing plate 6, ensuring the structural stability of the rainproof surface. The limiting block 14 is provided on both sides of the movable groove, and the driving component is provided on one side of the limiting block 14. The driving component is located on the inner wall of the fixing block 13. The driving components include a first motor 15, a rotating rod, a sliding plate 16, and a push plate 17. The first motor 15 is fixedly connected to the inner wall of the middle part of the fixed block 13. The first motor 15 is fixedly connected to the rotating rod. One side of the rotating rod is rotatably connected to the inner wall of the fixed block 13. The sliding plate 16 is threadedly connected to the rotating rod. Both sides of the sliding plate 16 are movably connected to the inner wall of the fixed block 13. The push plate 17 is hinged to both ends of the sliding plate 16. The bottom end of the push plate 17 is hinged to the limiting block 14. The limiting block 14 is movably connected to the inner wall of the fixed block 13. The limiting block 14 is inserted into the limiting groove 12.

[0025] When the two second electric push rods 9 on the inner wall of the mounting block 3 extend synchronously, they push the connecting plate 10 connected to it to move along the inner wall of the mounting block 3 towards the direction of the fixed plate 6, until the movable plate 11 at the end of the connecting plate 10 corresponds to the movable slot of the fixed block 13 on both sides of the fixed plate 6 and completes the insertion; then, the first motor 15 on the inner wall of the fixed block 13 starts, driving the rotating rod to rotate around its own axis, and through the threaded engagement, driving the sliding plate 16 to move vertically downward along the inner wall of the fixed block 13. The sliding plate 16 pushes the limiting blocks 14 on both sides to move along the inner wall of the fixed block 13 towards the direction of the movable plate 11 through the push plates 17 hinged at both ends, until the limiting blocks 14 are inserted into the limiting slots 12 on both sides of the movable plate 11, thereby locking and fixing the movable plate 11, and thus splicing the connecting parts of the mounting blocks 3 on both sides with the middle fixed plate 6 to form a complete and sealed rainproof surface. When it is not necessary to use When the rainproof mechanism is in use, the first electric push rod 5 moves the fixed plate 6, fixed block 13, connecting piece and mounting block 3 to the top of the equipment box 1. The first motor 15 is started to drive the rotating rod to rotate in the opposite direction. Through the threaded engagement, the sliding plate 16 moves vertically upward along the inner wall of the fixed block 13. The sliding plate 16 pulls the push plate 17, which in turn moves the limiting block 14 along the inner wall of the fixed block 13 away from the movable plate 11, so that the limiting block 14 is disengaged from the limiting groove 12 of the movable plate 11, and the locking and fixing of the movable plate 11 is released. Subsequently, the movable plate 11 retracts and resets along the groove of the connecting plate 10. The two second electric push rods 9 retract synchronously, pulling the connecting plate 10 along the inner wall of the mounting block 3 towards the inner wall of the mounting block 3, until the connecting plate 10 is housed inside the mounting block 3, so that the connecting plate 10 moves the movable plate 11 to its original position and is protected by the protective mechanism.

[0026] like Figures 3 to 4 As shown, a protective mechanism is provided between the movable plate 11 and the fixed block 13. The protective mechanism includes two telescopic blocks 18, a connecting block 19, a moving structure, and a third electric push rod 20. The two telescopic blocks 18 are respectively located on the outside of the movable plate 11 and the fixed block 13, and are connected by the connecting block 19. A moving structure is provided inside the connecting block 19 to drive the telescopic blocks 18 to extend and retract, thereby achieving synchronous movement of the telescopic blocks 18. A fixing groove is provided on the top of the equipment box 1, and the third electric push rod 20 is fixedly connected in the fixing groove. The top of the third electric push rod is fixedly connected to the bottom of the connecting block 19. The telescopic ends of the two telescopic blocks 18 are located on the outside of the movable plate 11 and the fixed block 13, respectively, which can protect the outside of the movable plate 11 and the fixed block 13. The fixed ends of the two telescopic blocks 18 and the connecting block 19 are located at the top of the fixing groove. The connecting block 19 is located at both ends of the telescopic blocks 18, and the moving structure is located symmetrically at the center of the telescopic blocks 18.

[0027] When rain protection is needed, the two telescopic blocks 18 retract synchronously through the moving structure, no longer protecting the outside of the movable plate 11 and the fixed block 13, exposing the movable plate 11 and the fixed block 13. Then, the third electric push rod 20 in the fixed groove is activated to retract, driving the connecting block 19 and the two telescopic blocks 18 to move vertically downward until the entire protective mechanism is completely housed in the fixed groove, avoiding interference with the splicing action of the rain protection mechanism.

[0028] like Figures 4 to 5 As shown, the moving structure includes a second motor 21, a movable rod 22, a gear 23, a first rack 24, and a second rack 25. The second motor 21 is fixedly connected to the inner wall of the top of the connecting block 19. The movable rod 22 is fixedly connected to the bottom of the second motor 21. The movable rod 22 is rotatably connected to the inner wall of the bottom of the connecting block 19. The gear 23 is fixedly connected to the middle of the movable rod 22. The first rack 24 and the second rack 25 are respectively meshed on both sides of the gear 23. The first rack 24 and the second rack 25 pass through the fixed end of the telescopic block 18 and are connected to the movable end of the telescopic block 18.

[0029] When the rainproof mechanism needs to be activated, the second motor 21 is started to drive the movable rod 22 to rotate. The movable rod 22 rotates around its own axis, which in turn drives the gear 23 to rotate. The gear 23 meshes with the first rack 24 and the second rack 25 to move in opposite directions, thereby pulling the telescopic ends of the two telescopic blocks 18 to retract into the fixed end, ensuring that the protective mechanism is completely retracted and avoiding interference with the splicing action of the rainproof mechanism. When the second motor 21 is started in reverse, the movable rod drives the gear 23 to rotate. The gear 23 meshes with the first rack 24 and the second rack 25 to move in opposite directions, thereby pushing the telescopic ends of the two telescopic blocks 18 to extend synchronously and respectively fit against the outer side of the movable plate 11 and the fixed block 13, thereby protecting the connecting parts and the fixed structure from damage by wind, sand, rain, and impact.

[0030] Working principle of this invention: Reference Figures 1 to 9 As shown, during use, the telescopic block 18 can protect the outer side of the movable plate 11 and the fixed plate 6 without blocking the through hole 2. The equipment box 1 has multiple through holes 2 arranged in a linear array on the top, which can discharge the heat generated by the electrical components inside the box, reduce the temperature rise inside the box, alleviate condensation and water accumulation, and ensure the normal transmission and reception of 4G antenna radio frequency signals, avoiding signal attenuation due to blockage.

[0031] When the rainproof mechanism is needed, the second motor 21 is started to drive the movable rod 22 to rotate, which in turn drives the movable rod 22 to rotate around its own axis, causing the gear 23 to rotate. The gear 23 meshes with the first rack 24 and the second rack 25 to move in opposite directions, thereby pulling the telescopic ends of the two telescopic blocks 18 to retract into the fixed ends, no longer protecting the outside of the movable plate 11 and the fixed block 13, exposing the movable plate 11 and the fixed block 13. Then, the third electric push rod 20 in the fixed groove is started to retract, driving the connecting block 19 and the two telescopic blocks 18 to move vertically downward until the entire protective mechanism is completely housed in the fixed groove. The two second electric push rods 9 on the inner wall of the mounting block 3 are started to push the connecting plate 10 along the inner wall of the mounting block 3 towards the fixed plate 6 until the movable plate 11 at the end of the connecting plate 10 is inserted into the groove of the fixed plate 6. The first motor 15 is started, driving the rotating rod to rotate around its own axis, which drives the sliding plate 16 along the fixed block 1 through the threaded engagement. 3. The inner wall moves vertically downward. The sliding plate 16 pushes the limiting blocks 14 on both sides along the inner wall of the fixed block 13 towards the movable plate 11 through the push plates 17 hinged at both ends. The limiting blocks 14 are inserted into the limiting grooves 12 on both sides of the movable plate 11, thereby locking and fixing the movable plate 11. When the first electric push rod 5 drives the fixed plate 6, the fixed plate 6, and the fixed structure to move upward, the mounting block 3, the connecting plate 10 and the movable plate 11 deflect. Since the connecting plate 10 is connected to the fixed structure through the movable plate 11, one end of the movable plate 11 moves out of the groove, increasing the length of the connecting plate 10, thereby adapting to the deflection of the overall structure. This makes it easier for the connecting parts of the mounting blocks 3 on both sides to be spliced ​​with the fixed plate 6 in the middle to form a complete and sealed rainproof surface, which fully covers the top and bottom of the equipment box 1, effectively preventing rainwater and dew from seeping in, preventing corrosion and short circuits of the internal 4G communication module, relays and other core components, and ensuring the normal operation of the terminal.

[0032] When the rainproof mechanism is not needed, the first electric push rod 5 moves the fixed plate 6, fixed block 13, connecting piece and mounting block 3 to the top of the equipment box 1. The first motor 15 is started to drive the rotating rod to rotate in the opposite direction. Through the threaded engagement, the sliding plate 16 moves vertically upward along the inner wall of the fixed block 13. The sliding plate 16 pulls the push plate 17, which in turn moves the limiting block 14 along the inner wall of the fixed block 13 away from the movable plate 11, so that the limiting block 14 disengages from the limiting groove 12 of the movable plate 11 and releases the locking fixation of the movable plate 11. Subsequently, the movable plate 11 retracts and resets along the groove of the connecting plate 10. The two second electric push rods 9 retract synchronously, pulling the connecting plate 10. Move along the inner wall of mounting block 3 close to the inner wall of mounting block 3 until the connecting plate 10 is housed inside mounting block 3, so that the connecting plate 10 drives the movable plate 11 to move to its original position, and then push the telescopic block 18 to the top of the equipment box 1 through the third electric push rod 20. Start the second motor 21 to reverse, so that the drive motor drives the gear 23 to rotate. The gear 23 meshes with the first rack 24 and the second rack 25 to move in opposite directions, thereby pushing the telescopic ends of the two telescopic blocks 18 to extend synchronously and fit against the outer side of the movable plate 11 and the fixed block 13 respectively, so as to protect the connecting parts and the fixed structure from wind, sand, rain and impact damage, so that the equipment box 1 can continue to be used.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
