Description

Technical Field

[0001] This invention relates to the field of power data acquisition device technology, specifically to a power data acquisition device that is easy to install. Background Technology

[0002] Power data acquisition devices, as key terminal equipment in smart grids and power consumption management systems, are widely installed in critical nodes such as distribution rooms, transformer substations, and user sides. They can monitor, measure, and upload core parameters such as current, voltage, power, and power quality in the lines in real time, providing the data foundation for intelligent operation and maintenance of the power grid, demand-side management, fault early warning, and energy efficiency analysis. The stability, accuracy, and real-time performance of the acquired data are of great significance for ensuring the safe operation of the power grid, improving operational management efficiency, and achieving refined power consumption control.

[0003] However, most existing power data acquisition devices adopt an integrated structure. These devices typically integrate the acquisition body, casing, and wiring terminals. The acquisition body is located inside the casing, and one end of the wiring terminal needs to pass through the casing to connect to the acquisition body's wiring. This makes installation cumbersome and inconvenient, preventing single-person operation. Installation requires multiple sets of bolts for tightening, and disassembly during maintenance and repair also requires tools and step-by-step operations, making the overall process tedious and time-consuming. Especially in high-altitude or confined spaces such as transformer platforms, pole-mounted switchgear, high-voltage cabinets, and small distribution panels, frequent disassembly and repair not only significantly extends working time, increases the risk of power outages and maintenance costs, but also poses higher construction safety hazards due to prolonged working at heights and in confined spaces. Summary of the Invention

[0004] An easy-to-install power data acquisition device includes a housing, a horizontal plate fixedly connected to the housing, a side cavity on the side wall of the housing, and multiple wire slots at the bottom of the horizontal plate, each slot housing a cable. The acquisition device body is mounted on the horizontal plate, abutting against the top surface of the horizontal plate. Multiple conductive elastic pressure plates are provided on the top surface of the horizontal plate, and multiple data acquisition contacts are correspondingly provided on the bottom surface of the acquisition device body. The number and position of the conductive elastic pressure plates, data acquisition contacts, wire slots, and cables are equal. The acquired data is transmitted to the controller of the acquisition device body for analysis and processing via the cables, conductive elastic pressure plates, and data acquisition contacts.

[0005] Furthermore, a cover plate is rotatably connected to the top of the device housing. A torsion spring is fixedly connected to each side of the cover plate. The end of the torsion spring away from the cover plate is fixedly connected to the device housing. A connecting rod is rotatably connected to the cover plate. A gear is rotatably connected to the end of the connecting rod away from the cover plate. A support plate is fixedly connected to the side cavity. A gear is rotatably connected to the support plate. A gear is slidably connected to the gear. An insert rod is slidably connected to the side wall of the device housing. The insert rod is inserted into the connecting rod. A tension spring is sleeved on the insert rod. A wire-gathering plate is fixedly connected to the bottom of the gear. The wire-gathering plate is slidably connected to the bottom of the device housing. Multiple fixed ring plates are fixedly connected to the wire-gathering plate in a linear array. Multiple rotating shafts are fixedly connected to the wire-gathering plate in a linear array. A rotating ring plate is rotatably connected to each rotating shaft.

[0006] Furthermore, the two ends of tension spring one are fixedly connected to the outer wall of the device housing and the end of the plug rod away from the device housing, respectively. Two torsion springs two are sleeved on each rotating shaft. The two ends of torsion springs two are fixedly connected to the rotating ring plate and the cable tray, respectively. Multiple sliding grooves are opened in a linear array on the cable tray. A guide rod is slidably connected to each rotating ring plate. A locking rod is slidably connected to each guide rod. The locking rod is slidably connected to the rotating ring plate. A tension spring two is sleeved on each guide rod. The two ends of tension spring two are fixedly connected to the locking rod and the rotating ring plate, respectively. Two support rods are symmetrically fixedly connected to the device horizontal plate. A connecting plate is slidably connected to the two support rods. Multiple pressure rods are fixedly connected in a linear array on the side of the connecting plate near the device horizontal plate. Two fastening bolts are threadedly connected to the connecting plate. Multiple slots are opened in a linear array on the device horizontal plate.

[0007] Furthermore, the main body of the acquisition device slides into the outer casing, and one side of the outer casing is designed with a hollow shape with an inwardly extending flange.

[0008] Furthermore, rack one is slidably connected to the support plate, and rack one and rack two are respectively meshed and connected on both sides of the gear.

[0009] Furthermore, the positions and numbers of the fixed ring plate, rotating ring plate, slots, and pressure rods all correspond to the wire insertion slots, and the inner surfaces of the fixed ring plate and rotating ring plate are both made of rubber material with anti-slip texture.

[0010] Furthermore, the sliding groove and the clamping rod are in sliding engagement, the clamping rod is hook-shaped, and the side of the clamping rod near the hub plate is set as an inclined surface.

[0011] Furthermore, the pressure rod and the slot are connected and interlocked, and the slot is connected to the corresponding wire insertion slot. The pressure rod is used to press the limit cable, and the fastening bolt is connected to the device's horizontal plate by a thread. The fastening bolt is used to lock the connecting plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are: The device adopts a three-part modular design consisting of the outer casing, the main body of the data acquisition device, and the cables. Each part has a clear functional division. The outer casing can be pre-fixed in scenarios such as power distribution rooms and transformers. Subsequent operations only require the main body of the data acquisition device and the cables. The modules do not interfere with each other, which facilitates the initial installation and layout and makes it easy to replace damaged parts individually later. This improves the overall flexibility and maintenance convenience of the power data acquisition device.

[0013] The data acquisition device can be installed and removed without the need for auxiliary tools. The installation and disassembly operations are simple and direct, which greatly simplifies the on-site construction and maintenance process, effectively reduces the complexity of operation and maintenance, and improves the efficiency of power data acquisition equipment replacement and maintenance.

[0014] The assembly and disassembly of the data acquisition device and the cable are carried out simultaneously. The device body is fixed in place and the cable is clamped and connected in sync. When disassembling, the plug-in pop-out structure is triggered, which releases the device body's limit and causes the cable plug-in part to move down and disconnect. This achieves an integrated assembly and disassembly process, avoiding the cumbersome operation of step-by-step wiring and fixing of traditional devices. It makes the assembly and disassembly process more coherent and efficient. The overall device has a high degree of integration and a simple structure and operation steps, which can better adapt to installation scenarios with limited space and complex environments, such as power distribution rooms and transformers, thus improving the device's scenario adaptability.

[0015] Each cable is individually clamped and fixed by an independent structure, and each cable has its own limiting space, which can prevent multiple cables from squeezing, tangling and shifting with each other. It can effectively resist environmental interference such as external vibration and external force contact, and always maintain the stability of the cable connection position. Structurally, it eliminates data acquisition abnormalities caused by cable loosening or displacement, and ensures the continuity and stability of power data acquisition. Attached Figure Description

[0018] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0019] Reference Figures 1 to 10 As shown, an easy-to-install power data acquisition device includes a device housing 11, a device horizontal plate 12 fixedly connected to the device housing 11, a side cavity 13 opened on the side wall of the device housing 11, a cover plate 14 rotatably connected to the top of the device housing 11, a torsion spring 15 fixedly connected to each side of the cover plate 14, the end of the torsion spring 15 away from the cover plate 14 being fixedly connected to the device housing 11, an acquisition device body 16 is provided inside the device housing 11, and multiple wire insertion slots 17 are opened in a linear array at the bottom of the device horizontal plate 12, and a cable 18 is inserted into each wire insertion slot 17.

[0020] Wherein: the main body 16 of the acquisition device is slidably engaged with the outer shell 11 of the device, and the main body 16 of the acquisition device is in contact with the top surface of the horizontal plate 12 of the device.

[0021] It should be noted that: one side of the device housing 11 is designed with a hollow shape with an inwardly extending flange. The purpose of the hollow part is to expose the operation panel area of ​​the acquisition device body 16, and the flange is used to limit the acquisition device body 16, so that the acquisition device body 16 can only slide upward and move out of the device housing 11.

[0022] It should be noted that: (Refer to) Figure 3 , Figure 7 As shown, the top surface of the device's horizontal plate 12 is arranged in a linear array with multiple conductive elastic pressure plates, and the bottom surface of the acquisition device body 16 is arranged in a linear array with multiple data acquisition contacts. The number of conductive elastic pressure plates, data acquisition contacts, and insertion slots 17 and cables 18 are equal and their positions correspond. When the cable 18 is inserted into the corresponding insertion slot 17, the cable 18 is connected to the corresponding conductive elastic pressure plate. During the process of the acquisition device body 16 being inserted and assembled into the device housing 11, the insertion part of the cable 18 moves upward, pressing the end of the cable 18 against the conductive elastic pressure plate of the device horizontal plate 12. As the acquisition device body 16 is placed on the device horizontal plate 12, the conductive elastic pressure plate of the device horizontal plate 12 is tightly attached to the acquisition contact of the acquisition device body 16, thereby realizing the conduction of current, voltage and other signals between the acquisition device body 16 and the cable 18. The acquired data is transmitted to the controller of the acquisition device body 16 for analysis and processing through the cable 18, the conductive elastic pressure plate and the data acquisition contact. That is, the acquisition device body 16 monitors the relevant power data in the cable 18 in real time.

[0023] Wherein: when the torsion spring 15 does not undergo elastic deformation, the cover plate 14 is completely flipped upward on the top of the device housing 11, exposing the top opening of the device housing 11.

[0024] Specifically: the device housing 11 can be installed in the required location, such as a power distribution room, transformer substation, user side and other key nodes, by bolts.

[0025] Among them, the side cavity 13 is used to contain the structure set inside it, so as to avoid the structure being exposed to the outside and being disturbed.

[0026] A connecting rod 21 is rotatably connected to the cover plate 14. A gear 22 is rotatably connected to the end of the connecting rod 21 away from the cover plate 14. A support plate 23 is fixedly connected inside the side cavity 13. A gear 24 is rotatably connected to the support plate 23. A gear 25 is slidably connected to the gear 24. An insert rod 26 is slidably connected to the side wall of the device housing 11. The insert rod 26 is inserted into the connecting rod 21. A tension spring 27 is sleeved on the insert rod 26. The two ends of the tension spring 27 are fixedly connected to the outer wall of the device housing 11 and the end of the insert rod 26 away from the device housing 11, respectively. A wire-gathering plate 28 is fixedly connected to the bottom end of the gear 25. The wire-gathering plate 28 is slidably connected to the bottom of the device housing 11. Multiple fixed ring plates 29 are fixedly connected in a linear array on the wire-gathering plate 28. Multiple rotating shafts 210 are fixedly connected in a linear array on the wire-gathering plate 28. Each rotating shaft 210 is rotatably connected to a rotating ring plate 211. Each rotating shaft 210 is sleeved with two fixed ring plates 211. A torsion spring 212 is fixedly connected at both ends to a rotating ring plate 211 and a hub plate 28, respectively. The hub plate 28 has multiple sliding slots 213 arranged in a straight line. Each rotating ring plate 211 has a guide rod 214 slidably connected to it. Each guide rod 214 has a locking rod 215 slidably connected to it. The locking rod 215 is slidably connected to the rotating ring plate 211. Each guide rod 214 has a tension spring 216 sleeved on it. The two ends of the tension spring 216 are fixedly connected to the locking rod 215 and the rotating ring plate 211, respectively. Two support rods 217 are symmetrically fixedly connected to the horizontal plate 12 of the device. A connecting plate 218 is slidably connected to both support rods 217. Multiple pressure rods 219 are fixedly connected in a straight line on the side of the connecting plate 218 near the horizontal plate 12 of the device. Two fastening bolts 220 are threadedly connected to the connecting plate 218. Multiple slots 221 are arranged in a straight line on the horizontal plate 12 of the device.

[0027] Among them, rack 1 22 is slidably connected to support plate 23, and rack 1 22 and rack 25 are respectively meshed and connected to both sides of gear 24.

[0028] It should be noted that, under the limiting sliding guide of the support plate 23, the first rack 22 and the second rack 25 can only move in a straight line in the vertical direction.

[0029] The insertion of the plug rod 26 and the connecting rod 21 serves to restrict the opening and closing of the cover plate 14.

[0030] Among them, the positions and numbers of the fixed ring plate 29, the rotating ring plate 211, the slot 221, and the pressure rod 219 all correspond to the insertion slot 17.

[0031] The inner surfaces of both the fixed ring plate 29 and the rotating ring plate 211 are made of rubber material with anti-slip texture.

[0032] Wherein: the sliding groove 213 and the locking rod 215 are in sliding fit, the locking rod 215 is configured as a hook shape, and the side of the locking rod 215 near the hub plate 28 is configured as an inclined surface.

[0033] Wherein: the pressure rod 219 is inserted into the slot 221, the slot 221 is connected to the corresponding wire insertion slot 17, and the pressure rod 219 is used to press the limiting cable 18.

[0034] Among them, the support rod 217 is used to restrict the movement of the connecting plate 218 and the pressure rod 219.

[0035] Among them, the fastening bolt 220 is threadedly connected to the device horizontal plate 12, and the fastening bolt 220 is used to lock the connecting plate 218.

[0036] Before the power data acquisition device is installed, the state of each structure is as follows: The torsion spring 15 did not undergo elastic deformation, and the cover plate 14 was completely flipped upwards on the top of the device housing 11, exposing the top opening of the device housing 11. The acquisition device body 16 was not yet inserted into the device housing 11, and the cable 18 was not yet inserted into the insertion slot 17. Because the cover plate 14 was flipped upwards, the cover plate 14 moved the rack 22 upwards to the highest position through the connecting rod 21. One end of the insertion rod 26 located in the side cavity 13 was not inserted into the connecting rod 21, and the insertion rod 26 abutted against the rack 22, causing the tension spring 27 to undergo elastic deformation. The second rack 25 drives the hub plate 28 to the lowest position on the device housing 11. The clamping rod 215 does not press against the hub plate 28. The second torsion spring 212 does not produce elastic deformation. The rotating ring plate 211 flips on the hub plate 28 to face the side away from the device housing 11. The second tension spring 216 does not produce elastic deformation. The fastening bolt 220 is not threaded on the device horizontal plate 12. The connecting plate 218 is located on the support rod 217 at the end away from the device horizontal plate 12. The pressure rod 219 is not inserted into the slot 221.

[0037] When installing the power data acquisition device, the staff first bolts the device housing 11 to the required location, such as a power distribution room, transformer substation, or user side. Afterward, the staff arranges the cables 18 to be connected, pressing them firmly onto the fixed ring plate 29, ensuring the cable connectors protrude from the top of the fixed ring plate 29. Then, the staff rotates the rotating ring plate 211 towards the fixed ring plate 29, causing it to rotate on the rotating shaft 210, simultaneously causing the torsion spring 212 to elastically deform. As the rotating ring plate 211 rotates towards the fixed ring plate 29, the inner surfaces of the fixed ring plate 29 and the rotating ring plate 211 gradually wrap around and compress the cable 18, confining it between the rotating ring plate 211 and the fixed ring plate 29.

[0038] Reference Figure 10As shown, during the rotation of the rotating ring plate 211 toward the fixed ring plate 29, the rotating ring plate 211 drives the locking rod 215 to rotate synchronously toward the moving groove 213 until the inclined surface of the locking rod 215 abuts against the groove wall of the moving groove 213. Under the guidance of the inclined surface, the locking rod 215 slides on the guide rod 214 toward the rotating ring plate 211, while causing the tension spring 216 to undergo elastic deformation. As the rotating ring plate 211 rotates, when the inclined surface of the locking rod 215 moves to the side of the cable hub 28 away from the rotating ring plate 211, the locking rod 215 no longer contacts or presses against the groove wall of the shifting groove 213. Then, under the elastic extension of the tension spring 216, the tension spring 216 pushes the locking rod 215 away from the rotating ring plate 211, causing the locking rod 215 to press against the end of the shifting groove 213 away from the rotating ring plate 211. Since the locking rod 215 is hook-shaped, it hooks onto the side of the cable hub 28 away from the rotating ring plate 211, thus preventing the rotating ring plate 211 from rotating away from the cable hub 28. This locks the rotating ring plate 211 onto the cable hub 28. At this time, the elastic deformation state of the torsion spring 212 is locked, and the rotating ring plate 211 and the fixed ring plate 29 lock and limit the cable 18 through the anti-slip textured rubber material on their inner surfaces.

[0039] It should be noted that the rubber parts on the inner surfaces of the fixed ring plate 29 and the rotating ring plate 211 can adapt to cables 18 of different diameters through the elastic deformation of the rubber, and can provide flexible clamping. Combined with the friction provided by the anti-slip texture, it can ensure the stable clamping of the cable 18 and the universality of cables 18 of different diameters.

[0040] When the user has completed the installation of all cables 18, the staff will insert the main body 16 of the acquisition device into the top opening of the device housing 11, so that the conductive elastic pressure plate of the device horizontal plate 12 is tightly attached to the acquisition contact of the acquisition device body 16. After completion, the user will rotate the cover plate 14 towards the device housing 11, so that the cover plate 14 is rotated to fit against the top of the device housing 11, at which point the top opening of the device housing 11 is blocked.

[0041] As the cover plate 14 rotates toward the outer casing 11 of the device until it closes, the cover plate 14 drives the rack 22 to move downward through the connecting rod 21, so that the rack 22 slides downward on the support plate 23. During the downward movement, the rack 22 meshes with and drives the gear 24 to rotate. At the same time as the gear 24 rotates, it meshes with and drives the rack 25 to move upward. That is, when the gear 24 rotates, the rack 22 and the rack 25 move in opposite directions in the vertical direction.

[0042] As the second rack 25 moves upward, the second rack 25 drives the hub plate 28 to slide vertically upward on the device housing 11. At this time, multiple cables 18 that are limited and installed on the hub plate 28 are simultaneously driven upward, so that the plug part of the cable 18 is inserted into the plug slot 17.

[0043] It should be noted that: since the cover plate 14 moves in a rotating opening and closing motion on the device housing 11, the rotation of the cover plate 14 on the device housing 11 will exert a force on the rack 22 to deflect obliquely. During this process, the connecting rod 21 rotates with the cover plate 14 and the rack 22 respectively through the rotation of its two ends. As the cover plate 14 rotates, the connecting rod 21 will rotate accordingly between the cover plate 14 and the rack 22, which can counteract the deflection effect of the cover plate 14 on the rack 22 and ensure that the rack 22 can move up and down with the opening and closing of the cover plate 14.

[0044] It should be noted that when the cover plate 14 is fully closed on the device housing 11, the connecting rod 21 moves to the position where it engages with the insertion rod 26. Then, under the elastic reset action of the tension spring 27, the insertion rod 26 engages with the connecting rod 21. The engagement of the insertion rod 26 with the connecting rod 21 restricts the rotation of the cover plate 14 on the device housing 11, thereby limiting the installation of the data acquisition device body 16 inside the device housing 11 and locking the elastic deformation state of the torsion spring 15.

[0045] After the cable 18 is inserted into the cable slot 17, the operator pushes the connecting plate 218 on the support rod 217 toward the device horizontal plate 12, so that the pressure rod 219 is inserted into the slot 221 and the end of the pressure rod 219 presses against the cable 18 in the cable slot 17. At this time, the operator tightens the fastening bolt 220 on the device horizontal plate 12, so that the connecting plate 218 and the pressure rod 219 are threadedly fastened on the device horizontal plate 12. At this time, the pressure rod 219 presses against and limits the cable 18, fixing the insertion state of the cable 18 in the cable slot 17.

[0046] It should be noted that at this time, the end of the cable 18 is pressed tightly against the conductive elastic plate of the device horizontal plate 12. Since the conductive elastic plate of the device horizontal plate 12 is in close contact with the acquisition contact of the acquisition device body 16, the current, voltage and other signals between the acquisition device body 16 and the cable 18 are connected, that is, the acquisition device body 16 monitors the relevant power data in the cable 18 in real time.

[0047] It should be noted that during the real-time monitoring of relevant power data within the cable 18 by the acquisition device body 16, the cable 18 is always wrapped and limited by the fixed ring plate 29 and the rotating ring plate 211, and the cable 18 is also pressed and limited by the pressure rod 219. This provides double protection for the installation status of the cable 18, preventing the cable 18 from being affected by the external environment and thus interfering with the acquisition of power data.

[0048] The installation of the power data acquisition device is now complete. If disassembly is required during the operation of the power data acquisition device, or if components such as the acquisition device body 16 or cable 18 are damaged and need to be replaced, the specific procedure is as follows: The operator first loosens the threaded fastening bolt 220, so that the connecting plate 218 is no longer confined on the device horizontal plate 12. Then, the operator moves the connecting plate 218 away from the device horizontal plate 12, so that the connecting plate 218 slides to the end of the support rod 217 away from the device horizontal plate 12. At the same time, the pressure rod 219 is pulled out from the slot 221, and the pressure rod 219 no longer abuts against the clamping cable 18. That is, the cable 18 is no longer confined on the device horizontal plate 12.

[0049] The staff then pulls the insertion rod 26 away from the device housing 11, causing it to be pulled out of the connecting rod 21. At the same time, the tension spring 27 undergoes elastic deformation. The insertion rod 26 no longer restricts the rotation of the cover plate 14. Then, under the elastic reset action of the torsion spring 15, the cover plate 14 flips onto the device housing 11 to face vertically upwards, exposing the top opening of the device housing 11. The staff can then remove the data collection device body 16 from the top opening of the device housing 11 for replacement or repair.

[0050] It should be noted that as the cover plate 14 flips upward, the cover plate 14 drives the connecting rod 21 and the toothed rod 22 to move upward. The connecting rod 21 is no longer in the insertion position of the insert rod 26. The insert rod 26 and the upward-moving toothed rod 22 come into contact and press against each other, locking the elastic deformation state of the tension spring 27. At this time, the user no longer needs to pull the insert rod 26.

[0051] During the process of the cover plate 14 flipping upwards, the cover plate 14 drives the first rack 22 to move vertically upwards via the connecting rod 21. As mentioned above, the first rack 22 and the second rack 25 move in opposite directions under the meshing of the gear 24. As the first rack 22 moves vertically upwards, the second rack 25 drives the cable collector 28 to move vertically downwards, causing the cable collector 28 to drive the multiple cables 18 that are limited on it to move vertically downwards. Thus, the multiple cables 18 are pulled downwards from the corresponding insertion slots 17. When the cover plate 14 flips to the vertically upwards position, the cable collector 28 drives the multiple cables 18 to move downwards to the lowest position on the device housing 11. There is a certain distance between this position and the insertion slots 17, which is to facilitate the operation of the cables 18 by the staff.

[0052] At this point, the user can selectively operate on a specific cable 18. The user pulls the lever 215 towards the direction of the second torsion spring 212, causing the lever 215 to slide along the sliding groove 213 and guide rod 214 towards the second torsion spring 212. Simultaneously, the second tension spring 216 undergoes elastic deformation. The lever 215 is no longer hooked onto the cable tray 28. As the lever 215 moves, it no longer restricts the elastic return of the second torsion spring 212. Under the elastic return action of the second torsion spring 212, it drives the rotating plate 211 to rotate and return to its original position on the rotating shaft 210, causing the rotating plate 211 to flip until it no longer contacts the cable 18. Once the lever 215 disengages from the sliding groove 213, the user can stop pulling it. At this point, under the elastic return action of the second tension spring 216, the second tension spring 216 pushes the lever 215 back to its original position. The rotating plate 211 no longer encloses and limits the cable 18, allowing the user to remove the cable 18 for operation.

[0053] It should be noted that by moving all the cables 18 down synchronously through the hub 28, all the cables 18 can still be neatly arranged on the hub 28 when the cable 18 is disconnected, thus avoiding the messy distribution of the cables 18 from affecting the user's operation. Furthermore, moving the cables 18 down to the lowest position allows the cables 18 to be in a wider operating space, which facilitates the user's operation of the cables 18.

[0054] It should be noted that since each cable 18 is installed independently, the user can selectively remove one or several cables 18 without affecting the remaining cables 18. The remaining cables 18 are still fixedly installed on the hub 28, which makes the user's operation of the cables 18 more organized and will not be disturbed by the surrounding cables 18 that do not need to be operated.

[0055] Beneficial effects The device adopts a three-part modular design consisting of the outer casing 11, the main body of the acquisition device 16, and the cable 18. The functions of each part are clearly defined. The outer casing 11 can be pre-fixed in scenarios such as power distribution rooms and transformers. Subsequently, only the main body of the acquisition device 16 and the cable 18 need to be operated. The modules do not interfere with each other, which facilitates the initial installation layout and the replacement of damaged parts later. This improves the overall flexibility and maintenance convenience of the power data acquisition device.

[0056] The data acquisition device body 16 can be installed and removed without the need for auxiliary tools. The installation and disassembly operations are simple and direct, which greatly simplifies the on-site construction and maintenance process, effectively reduces the complexity of operation and maintenance, and improves the efficiency of power data acquisition equipment replacement and maintenance.

[0057] The assembly and disassembly of the data acquisition device body 16 and the cable 18 are carried out simultaneously. The data acquisition device body 16 is fixed in place and the cable 18 is pressed and connected in a synchronous manner. When disassembling, the plug-in pop-out structure is triggered, which simultaneously releases the limit of the data acquisition device body 16 and causes the plug-in part of the cable 18 to move down and disconnect. This realizes the integrated completion of the assembly and disassembly action, avoiding the cumbersome operation of step-by-step wiring and fixation of traditional devices. It makes the assembly and disassembly process more coherent and efficient. The overall device has a high degree of integration and a simple structure and operation steps. It can better adapt to installation scenarios with limited space and complex environment, such as power distribution rooms and transformers, and improve the device's scenario adaptability.

[0058] Each cable 18 is clamped and fixed by an independent structure, and each cable 18 has its own limiting space, which can prevent multiple cables 18 from squeezing, tangling and shifting with each other. It can effectively resist environmental interference such as external vibration and external force contact, and always maintain the stability of the connection position of the cable 18. Structurally, it eliminates the abnormal data acquisition caused by the loosening or displacement of the cable 18, and ensures the continuity and stability of power data acquisition.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
