Description

Technical Field

[0001] This utility model relates to the field of power maintenance technology, and in particular to an intelligent grounding wire storage device based on the Internet of Things and non-contact detection. Background Technology

[0002] Existing grounding wire storage devices, such as the patent "An Intelligent Grounding Wire Storage Device" with publication number CN116038519A, have many problems.

[0003] First, the detection method is limited to mechanical probe contact detection. In actual operation, this method involves direct contact between the probe and the grounding wire insulation layer, which may cause secondary damage to the insulation layer with long-term use, affecting the insulation performance of the grounding wire and increasing electrical safety hazards. Patent CN207850325U, "A Measuring Device for Wire Insulation Layer Thickness," provides an inspiration for measuring insulation layer thickness using ultrasound; however, this device is a single unit and lacks a complete set of equipment to match the grounding wire's storage or release.

[0004] Secondly, the level of intelligence is severely insufficient. Most existing devices can only achieve local button control and lack remote monitoring and data analysis functions. Maintenance personnel need to go to the site in person to check the status of the device, and cannot grasp the various parameters of the grounding wire in real time, resulting in low maintenance efficiency and failure to detect and deal with potential problems in a timely manner.

[0005] Furthermore, the structural design is relatively fixed. Its storage tray is usually fixed and cannot be adapted to different specifications of grounding wires. When faced with grounding rods of various diameters, it is difficult to meet the actual use requirements. Moreover, the device as a whole lacks adaptability to complex environments, and its use is limited in special scenarios such as different substation layouts or field emergency repairs.

[0006] Finally, the issue of energy dependence is prominent. Existing devices generally require external power supply. In outdoor scenarios, the limited availability of power sources restricts their flexible use, especially in remote areas or during emergency repairs, where the difficulty in obtaining external power severely hinders the normal operation of the devices.

The rotating shaft passes through the torque sensor and its two ends rotate through the bearing housings on the corresponding sides. The sensing end of the torque sensor forms an inductive engagement with the rotating shaft. One end of the rotating shaft rotates synchronously with the output shaft of the variable frequency speed control motor through a first coupling, and the other end of the rotating shaft rotates synchronously with the rotating shaft of the storage assembly through a second coupling.

[0020] The embodiments will be further described below with reference to the accompanying drawings.

[0021] like Figures 1-7As shown in the preferred embodiment 1, the intelligent grounding wire storage device based on the Internet of Things and non-contact detection includes a mobile cart 1. The mobile cart 1 is equipped with an ultrasonic detection component 2, a drive component 3, a storage component 4, and a control component 6. The ultrasonic detection component 2 and the drive component 3 are both electrically connected to the control component 6. The grounding wire on the outside of the cart is guided by the ultrasonic detection component 2 and the thickness of the insulating layer is detected by ultrasonic waves before being wound onto the detachable storage tray 401 of the storage component 4. The storage tray 401 is provided with rotational power by the drive component 3. The drive component 3 is linked with the torque sensor 301 through the control component 6.

[0022] In a preferred embodiment 2, the mobile cart 1 is detachable. The mobile cart 1 includes a bottom plate 102 and a top plate 103 arranged vertically opposite each other. The four corners of the bottom plate 102 and the four corners of the top plate 103 are respectively supported and fixed by support rods 104. The bottom plate 102 and the top plate 103, together with the support rods 104, form a square frame with a sealed top and a sealed bottom. The bases at both ends of the support rods 104 are detachably fixed to the corresponding side of the bottom plate 102 or the top plate 103 by fasteners. The side of the bottom plate 102 away from the support rods 104 All four corners are equipped with casters 101. The side walls of the directional frame have space for the installation of baffles 105. The side walls of the square frame are closed by the corresponding baffles 105. Both sides of the baffles 105 are fixedly engaged with one side of the corresponding support rod 104 by several fasteners. The side of the baffle 105 near the ultrasonic testing component 2 is provided with an inlet 108 for the ground wire to pass through. The side of the baffle 105 near the storage component 4 is provided with an operating door 106. The operating door 106 is used to inspect the internal devices, install or remove the storage tray, and can be locked and opened.

[0023] As a more preferred embodiment 3, the top outer side of the cover plate 105 is provided with a handle 107, which facilitates the movement of the vehicle body after applying force.

[0024] In a preferred embodiment 4, the ultrasonic testing component 2 is mounted on the first raised platform 7, and the bottom of the first raised platform 7 is detachably fixed to the bottom of the mobile platform 1 via a base and fasteners.

[0025] In a preferred embodiment 5, the drive assembly 3 is mounted on the second raised platform 8. The bottom of the second raised platform 8 is detachably fixed to the bottom of the mobile platform 1 via a base and fasteners, and the storage assembly 4 is located on the side of the second raised platform 8 and does not contact the second raised platform 8.

[0026] The first elevation frame 7 and the second elevation frame 8 are used to adjust the height of the ultrasonic testing component 2 and the drive component 3, respectively, so that the ground wire can be successfully guided and stored. At the same time, the second elevation frame 8 is also used to prevent the storage tray 401 from interfering with the vehicle body, and to raise the bottom of the vertically arranged storage tray 401 to facilitate rotation.

[0027] In a preferred embodiment 6, the ultrasonic testing component 2 includes a first guide roller 201 and a second guide roller 202 rotatably mounted on the top of the first raised frame 7. The ground wire is guided through the first guide roller 201 to the second guide roller 202, and then through the second guide roller 202 to the receiving component 4 for winding. The guiding portion of the first guide roller 201 is flush with the guiding portion of the second guide roller 202 to keep the ground wire horizontal. A mounting support 203 is provided on the first raised frame 7 between the first guide roller 201 and the second guide roller 202. A standard plate 205 is provided at the bottom of the mounting support 203, and an ultrasonic probe 204 is provided at the top of the mounting support 203. The output end of the ultrasonic probe 204 faces the standard plate 205, and the ultrasonic probe 204 and the standard plate 205 form a hollow detection structure through the mounting support 203. The ground wire passes between the ultrasonic probe 204 and the standard plate 205 and is detected by ultrasonic waves. An ultrasonic generator 206 is provided on one side of the first raised frame 7, and the ultrasonic generator 206 is signal connected to the ultrasonic probe 204.

[0028] Two guide rollers with flush guide sections are used to ensure the straightness of the ground wire during the guiding process, which makes it easier to ensure the accuracy of ultrasonic testing. The ground wire is tested when it passes through the ultrasonic probe 204 and the standard plate 205. The test signal is sent to the controller for processing, and the processed data is sent to the cloud computer to obtain real-time reports and data display. The user terminal can read the data in real time, so as to know the insulation layer thickness of the ground wire at that point at any time. The thickness data can be used to determine whether the insulation layer is damaged, without the need to use a probe or directly let the testing device come into contact with the ground wire, thus avoiding damage to the ground wire.

[0029] As a more preferred embodiment 7, the ultrasonic detection component 2 includes a first guide roller 201 and a second guide roller 202 rotatably disposed on the top of the first raised frame 7. The ground wire is guided from the top of the first guide roller 201 to the top of the second guide roller 202, and from the top of the second guide roller 202 to the bottom of the receiving component 4 for upward winding. The top of the first guide roller 201 is flush with the top of the second guide roller 202 to keep the ground wire horizontal.

[0030] The drive speed may be adjusted at any time based on the feedback from the torque sensor 301. The ground wire is kept as straight as possible but not necessarily taut. Therefore, when the ground wire tension is small, the ground wire can rest on the two guide rollers without directly contacting the ultrasonic testing device. This method also makes it easier to set up the ultrasonic testing device.

[0031] In a preferred embodiment 8, the drive assembly 3 includes a variable frequency speed control motor 302 and bearing seats 304 mounted on the second raised frame 8. There are two bearing seats 304 arranged opposite each other. A torque sensor 301 is located between the bearing seats 304. A rotating shaft 305 passes through the torque sensor 301 and its two ends rotate through the bearing seats 304 on the corresponding sides. The sensing end of the torque sensor 301 forms a sensing engagement with the rotating shaft 305. One end of the rotating shaft 305 rotates synchronously with the output shaft of the variable frequency speed control motor 302 through a first coupling 303. The other end of the rotating shaft 305 rotates synchronously with the rotating shaft of the storage assembly 4 through a second coupling 306.

[0032] The storage tray 401 and the mounting tray 402 rotate synchronously, and the mounting tray 402 and the rotating shaft 305 rotate synchronously. The tension of the ground wire storage can be measured in real time indirectly through the torque sensor 301. When the monitored data exceeds the maximum value of the set range, it indicates that the tension is too high and the storage is too tight. At this time, the controller of the control component 6 reduces the speed of the variable frequency speed control motor 302 until the monitored data returns to the set range and remains unchanged. When the monitored data is lower than the minimum value of the set range, it indicates that the tension is too low and the storage is too loose. At this time, the controller of the control component 6 increases the speed of the variable frequency speed control motor 302 until the monitored data returns to the set range and remains unchanged.

[0033] As a preferred embodiment 9, the storage component 4 includes a vertically arranged mounting plate 402. A rotating shaft is provided at the middle position of one side of the mounting plate 402 and is linked to the drive component 3. A screw 403 is provided at the middle position of the other side of the mounting plate 402. A plurality of limiting rods 404 are provided at equal intervals around the screw 403 on the mounting plate 402 on the same side as the screw 403, and both the screw 403 and the limiting rods 404 are perpendicular to the mounting plate 402. The storage tray 401 has a central hole 406 corresponding to the screw 403 at the middle position. The storage tray 401 has a number of limiting holes 405 at equal intervals around the central hole 406, and the limiting holes 405 correspond one-to-one with the limiting rods 404. When the screw 403 passes through the central hole 406, the limiting rods 404 all pass through the corresponding limiting rods 404 to form a limiting fit. The storage tray 401 is pressed and fixed between the pressing plate 407 and the mounting plate 402 by the pressing plate 407.

[0034] The storage tray 401 can be replaced at any time, and the installation and docking are convenient. Simply pass the stud 403 through the center hole 406 and rotate the storage tray 401 so that the limit rods 404 pass through the corresponding limit holes 405 to complete the docking and installation. The limit rods 404 can also ensure that the storage tray 401 and the installation tray 402 rotate synchronously.

[0035] As a more preferred embodiment 10, a screw hole 408 is provided at the middle position of the pressing plate 407 to be threadedly engaged with the screw 403. A rotating handle 409 is rotatably mounted on the side of the pressing plate 407 away from the receiving plate 401 via a bearing. The rotation center axis of the rotating handle 409 is parallel to the center axis of the screw hole 408. The radius of the pressing plate 407 is less than the minimum distance between the screw 403 and the limiting rod 404.

[0036] To ensure a secure installation, during installation, rotate the handle 409 around the screw 403, causing the handle 409 to revolve around the screw 403. As the handle 409 revolves, it drives the clamping plate 407 to rotate around the screw 403. Through the threaded engagement of the screw hole 408 and the screw 403, the clamping plate 407 and the mounting plate 402 are engaged to clamp the storage plate 401, ensuring the stability of the synchronous rotation of the storage plate 401.

[0037] As a more preferred embodiment 11, the mobile cart 1 is equipped with a solar power supply component 5 to provide energy to the ultrasonic detection component 2, the drive component 3, the storage component 4 and the control component 6; The solar power supply component 5 includes a flexible solar panel 501 mounted on the roof of the mobile flatbed 1 and a solar power generation hardware assembly 502 mounted inside the mobile flatbed 1, which is used to provide energy to the ultrasonic detection component 2, the drive component 3, the storage component 4 and the control component 6. The solar power supply component 5 includes a flexible solar panel 501 mounted on the roof of the mobile flatbed 1 and a solar power generation hardware assembly 502 mounted inside the mobile flatbed 1. The solar power generation hardware assembly 502 includes a dedicated solar power generation controller electrically connected to the flexible solar panel 501, the dedicated solar power generation controller being electrically connected to the battery, and the dedicated solar power generation controller being electrically connected to the control assembly 6 via an inverter.

[0038] It provides clean energy and can be used in places where there is no power supply or it is inconvenient to use. When charging, the flexible solar panel 501 converts solar energy into electrical energy, which is then stored in the battery by a dedicated solar power generation controller. When in use, the electrical energy is transferred from the battery by the dedicated solar power generation controller, converted by the inverter, and then supplied to each electrically connected component through the control component 6.

[0039] As a more preferred embodiment 12, the control component 6 includes a programmable PLC controller, a memory, and a communication terminal. Ultrasonic detection data enters the controller for processing and is stored in the memory. At the same time, the controller communicates with a cloud computer through the communication terminal, and the user terminal communicates with the cloud computer to obtain data in real time.

[0040] The communication terminal includes an embedded 4G / 5G communication module for enabling high-speed data transmission between the device and the cloud and mobile devices; The control component 6 also includes a GPS positioning module, which can accurately locate the device and facilitate quick location by maintenance personnel; The memory is used to locally store detection data, device operating status, and other information.

[0041] On the software side, cloud-based computers and user terminals work together, such as a mobile app. The cloud-based computer receives, processes, and stores data uploaded from the device, performing data analysis and management. The user terminal provides maintenance personnel with a user-friendly interface, supporting remote command issuance, such as commands to retract or extend the grounding wire. Simultaneously, it can monitor the device status in real time, including insulation integrity and retraction progress. This module also has the function of automatically generating maintenance reports, periodically generating detailed reports based on device operating data and test results, facilitating maintenance personnel's understanding of equipment operation. When anomalies are detected, such as damaged grounding wire insulation or low device power, alarm information will be promptly pushed to maintenance personnel.

[0042] As a more preferred embodiment 13, suppose that in a substation, maintenance personnel need to retract a set of grounding wires. First, the maintenance personnel open the user terminal, i.e., the mobile APP, and send a "retract" command through the APP. The command is transmitted to the cloud computer via the 4G / 5G network, and then the cloud computer sends it to the intelligent grounding wire retracting device. After receiving the command, the device starts the drive component and automatically unfolds the grounding wires. During the unfolding process, the ultrasonic detection component 2 starts working and scans and detects the insulation layer of the grounding wires. The detection data is uploaded to the cloud computer in real time through the controller and communication terminal to determine the wear condition. If the wear of the insulation layer is found to exceed 30%, the cloud management platform immediately triggers an alarm, pushes alarm information to the maintenance personnel through the APP, and suspends the retracting operation, prompting the maintenance personnel to replace the grounding wires. At the same time, the cloud management platform and the APP interface will display detailed information such as the location and degree of wear, which is convenient for maintenance personnel to handle.

[0043] As a more preferred embodiment 14, at a field power emergency repair site, workers install the device, ensuring the intelligent grounding wire storage device is placed stably. The flexible solar panel 501 on top of the device begins to receive solar energy and convert it into electrical energy to power the device, ensuring that the device can work continuously in the field without an external power source.

[0044] The working principle of this utility model: In use, driven by the drive component 3, the storage tray 401 of the storage component 4 rotates to wind and store the ground wire. The ground wire is guided to the storage tray by the ultrasonic detection component 2. During the guidance process, the thickness of the insulation layer of the ground wire is detected by the ultrasonic probe 204 and the control component 6 to determine whether the ground wire is damaged. The drive component 3 judges the tension of the ground wire storage in real time through the torque sensor 301, and then adjusts the winding speed in real time by the control component 6. During the process, the ultrasonic probe 204 does not directly contact the ground wire to reduce the chance of damage. At the same time, a communication terminal is equipped to upload data. The solar power supply component 5 can also ensure the use of clean energy and can be used when it is impossible to connect an external power cord.
