Description

Technical Field

[0001] This utility model relates to the field of busbar maintenance technology, and in particular to a portable tool kit for busbar maintenance. Background Technology

[0002] Traditional busbar maintenance methods rely on multiple independent tools, lacking integrated design. Each maintenance operation requires selecting and carrying multiple corresponding independent tools, leading to problems such as tool loss and chaotic tool management. Existing testing tools typically only support a single function (such as temperature or resistance measurement), and the data collected during maintenance cannot be automatically recorded. Manual paper-based record-keeping is necessary, which is time-consuming, labor-intensive, costly, and prone to omissions and errors. Furthermore, it cannot directly integrate infrared imaging, contact resistance, and insulation test parameters, and it is difficult to quickly generate structured reports with multi-dimensional data. Some testing instruments (such as micro-ohmmeters and clamp multimeters) require separate charging or battery replacement, which may lead to insufficient power during prolonged operation, affecting maintenance efficiency. Therefore, existing technologies struggle to simultaneously meet the requirements of tool portability, automatic data transmission and integration, and power management. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the technical problem this invention aims to solve is to provide a portable tool kit for busbar maintenance that integrates tools and testing instruments and can automatically connect via Bluetooth to read and transmit testing data.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a portable tool kit for busbar maintenance, comprising a box body composed of two front and rear covers hinged together on one side. The box covers contain a rechargeable battery box, a lithium battery, a processor, a storage unit, a Bluetooth module, and multiple slots for placing testing instruments or tools. Each slot for placing testing instruments has a pressure-sensitive switch that can contact and be pressed against the surface of the placed instrument. The rechargeable battery box, lithium battery, Bluetooth module, pressure-sensitive switch, and storage unit are all electrically connected to the processor. A USB interface is provided through the wall of the box covers, and the processor is electrically connected to the USB interface. The testing instruments have a Bluetooth module.

[0006] As an improvement to the technical solution of the portable tool kit for busbar maintenance of this utility model, the tool slot for placing tools is provided with a micro switch that can contact and be squeezed with the surface of the placed tool.

[0007] As an improvement to the technical solution of the portable tool kit for busbar maintenance of this utility model, the box is also equipped with a touch screen, a camera module, and an infrared thermal imaging module that are electrically connected to the processor.

[0008] As an improvement to the technical solution of the portable tool kit for busbar maintenance of this utility model, the rechargeable battery box is offset to one side and has an opening on the side of the box cover so that the rechargeable battery box can be pulled out from the side; the box cover has a bracket to support the rechargeable battery box, the rechargeable battery box is a drawer box with sliders on both sides, and the bracket has a slide that matches the sliders.

[0009] As an improvement to the technical solution of the portable tool kit for busbar maintenance of this utility model, the side of the rechargeable battery box is provided with a protruding buckle, the bracket body is hinged with a locking body that can swing laterally, the locking body is provided with a locking protrusion that can lock the protruding buckle, and the bracket body is slidably fitted with a push button that can partially extend out of the box cover. The push button can swing and unlock by laterally contacting the locking body.

[0010] As an improvement to the technical solution of the portable tool kit for busbar maintenance of this utility model, the inner end of the locking body is raised towards the pressing button, and the side of the pressing button bulges towards the locking body to form a push block.

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0021] like Figure 1 , Figure 2 , Figure 3As shown, this utility model discloses a portable tool kit for busbar maintenance, which includes a box body 11 composed of two front and rear covers 19 that are hinged to each other on one side. The box cover 19 contains a rechargeable battery box 13, a lithium battery 14, a processor 21, a storage unit 22, a Bluetooth module 23, and multiple tool slots 15 for placing testing instruments or tools. The rechargeable battery box 13, lithium battery 14, processor 21, storage unit 22, and Bluetooth module 23 are stably installed in the box body 11, forming an attached connection. The remaining space of the two box covers 19 of the box body 11 is also provided with multiple tool slots 15, some of which are tool slots 15b, and others are tool slots 15a, which are used to place testing instruments. The tool slot 15b can hold tools such as a voltage tester 51, a torque wrench 52, conductive paste 53, and a retractable warning line 54. The instrument slot 15a can hold instruments such as a micro-ohmmeter 55, an ultraviolet imager 56, and a clamp multimeter 58. The instrument slot 15a has a locking protrusion to hold the instrument placed inside. The instrument slot 15a has a pressure switch 18 that can contact and be squeezed with the surface of the placed instrument. The rechargeable battery box 13, lithium battery 14, Bluetooth module 23, pressure switch 18, and storage unit 22 are all electrically connected to the processor 21. Contact or squeezing causes the pressure switch 18 to feed back a switch signal and transmit it to the processor 21 through the communication connection formed by electrical conduction, so that the pressure switch 18 can sense whether the corresponding instrument has been taken for use. The instrument has a Bluetooth module and can communicate with the Bluetooth module set in the cover 19. If the testing instrument is taken out for use, the processor 21 receives the feedback signal and knows what kind of testing instrument it is. Then, it instructs the Bluetooth module set in the cover 19 to actively search for the Bluetooth module of the corresponding testing instrument, connect to it, read and transmit the testing data obtained by the testing instrument, and then put it into the storage unit 22, realizing automatic data reading and storage.

[0022] This technical solution integrates commonly used tools such as an infrared thermal imager / module 29, a micro-ohmmeter 55, an insulation tester, and a torque wrench 52 into a portable case, forming an integrated toolbox and avoiding the inconvenience of carrying tools separately. The case 11, formed by the two hinged lids 19, features unique recessed compartments for various common maintenance tools, allowing for better placement and storage of individual tools.

[0023] A USB port 25 is provided through the wall of the case cover 19. The processor 21 is electrically connected to the USB port 25, allowing the lithium battery 14 inside the case cover 19 to be charged via an external power source. The processor 21 can also charge the batteries inside the battery compartment 13, ensuring they are fully charged for standby. The charging process can be controlled by the processor 21. The case cover 19 also has an indicator light 26 to indicate the connection status of the USB port 25 or the connection status of the Bluetooth module.

[0024] The toolbox contains a lithium battery 14, a rechargeable battery box 13, and a spare battery. While charging the lithium battery 14, the spare battery is also charged. However, during prolonged use of other tools in the toolbox that require separate charging or battery replacement, such as a micro-ohmmeter or clamp multimeter, insufficient power may occur. If power is insufficient, maintenance personnel can remove the spare battery from the rechargeable battery box for replacement, ensuring uninterrupted maintenance and avoiding any impact on efficiency.

[0025] The inclusion of a Bluetooth module allows external networks to quickly locate the toolbox, enabling rapid searching. Bluetooth connectivity also facilitates instant data exchange: technicians can connect to the Raspberry Pi via Bluetooth using mobile devices (smartphones) to immediately view toolbox usage data and export reports.

[0026] The pressure switch 51 is a microswitch. More preferably, the tool slot 15b is equipped with a microswitch that can contact and be pressed against the surface of the placed tool. A slight touch can provide a feedback signal to the processor, informing it of the abnormal status of the tool slot, whether a tool / inspection instrument has been placed in or removed. The processor 21 and the storage unit 22 are both components of the Raspberry Pi 12, enabling the Raspberry Pi 12 to have data reading, processing, and storage functions. Furthermore, the microswitches in each tool slot are electrically connected to different GPIO pins of the Raspberry Pi. Figure 5 As shown, when tools are not in use, they are placed in the tool slot. When the microswitch is pressed, the Raspberry Pi knows that the tool is not in use and enters a sleep state. When a tool is used, the technician picks it up, the microswitch pops up, and the Raspberry Pi knows which tool is in use, starts working, and records the usage time of that tool. When the tool is finished using it, it is put back in the slot, the microswitch is pressed again, the Raspberry Pi knows that the tool has finished using it, pauses the timer, and fills in the maintenance report. Moreover, after each tool has been idle for a period of time, the Raspberry Pi re-enters a sleep state to save power.

[0027] The housing 11 also includes a touchscreen display 27, a camera module 28, and an infrared thermal imaging module 29, all electrically connected to the processor 21. The touchscreen display 27 allows for manual data processing, including data selection and integration, and displays the read data, facilitating real-time review and analysis. The camera module 28 and infrared thermal imaging module 29 acquire sensory image data of the maintenance process and record multiple intermittent frames, enabling a more intuitive review of the process. Key images are recorded and integrated into a comprehensive data table or database for verification and subsequent problem-solving discussions.

[0028] like Figure 1 As shown, this technical solution integrates the infrared imaging module 29 and the camera module 28 into the Raspberry Pi. After the maintenance personnel use them, the relevant data is automatically entered into the Raspberry Pi, thereby realizing the linkage between the toolbox and the mobile device. For other maintenance tools that are not yet integrated into the Raspberry Pi, such as the ultraviolet imager 56 and the micro-ohmmeter 55, the maintenance personnel can connect the mobile device to the toolbox Raspberry Pi 12 via Bluetooth after using the tool. Then, they can access the corresponding application of the toolbox Raspberry Pi 12 on the mobile device and enter the relevant measurement data of the tool they just used so that the Raspberry Pi 12 can generate a structured report later.

[0029] By integrating with multiple modules via a built-in Raspberry Pi, it can record action data, which can then be exported to standard format files or integrated with other systems for data transfer. The corresponding returned data includes: tool usage time, inspection photos, infrared imaging results, number of times other tools were used, and usage duration. By automatically storing inspection data and generating reports, it saves more than 50% of time compared to manual recording, making it particularly suitable for the maintenance of large-scale power distribution systems. Furthermore, the entire maintenance process can be recorded, including the time of each maintenance operation and the automatic archiving of inspection data, facilitating quality traceability and compliance auditing.

[0030] Among them, such as Figure 2 As shown, the rechargeable battery box 13 is offset to one side, and an opening is provided on the side of the corresponding lid 19, allowing the rechargeable battery box 13 to be pulled out from the side. This allows the rechargeable battery box 13 to be pulled out from the side even when the lid 19 is closed, enabling the access of spare batteries for use with other external instruments or for replacing a batch of spare batteries for charging. When a batch of spare batteries needs to be replaced, they can also be retrieved from the side without opening the lid. The lid 19 contains a support body 61 that supports the rechargeable battery box 13. The rechargeable battery box 13 is a drawer-shaped box with sliders 32 on both sides. The support body 61 has a slide rail 62 that matches the sliders 32, facilitating the sliding and pulling of the rechargeable battery box 13.

[0031] More preferably, the side of the charging battery box 31 is provided with a protruding buckle 33, and the bracket body 61 is hinged with a locking body 63 that can swing laterally. The locking body 63 is provided with a locking protrusion 64 that can lock the protruding buckle 33. Normally, the locking protrusion 64 blocks the protruding buckle 33, thereby preventing the charging battery box 31 from sliding and avoiding accidental sliding that would cause the charging battery box 31 to slide out from the side. The bracket body 61 is slidably fitted with a push button 65 that can partially extend out of the box cover 19. When the push button 65 is pushed inward, the push button can laterally abut against the locking body 63, causing its inner tail end to swing towards the charging battery box 31, while the front end, together with the locking protrusion 64, swings away from the charging battery box 31, causing the locking protrusion 64 to separate from the protruding buckle 33 and release the obstruction of the protruding buckle 33, thereby unlocking the charging battery box 31. The inner support 61 is equipped with a spring plate 41 that presses the inner end of the button 65 to keep it away from the charging battery box 31, thus maintaining the charging battery box 31 in its normally closed state. The button 65 has a pressing push rod 66 inside the box, and the support body 61 has a rod groove for the pressing push rod 66 to slide. The limiting plate 69 of the rod groove extends inward to allow it to slide inward a certain distance.

[0032] Furthermore, the locking body 63 is curved, or the connection between the two straight arms can be a curved connection structure; the inner end of the locking body 63 protrudes towards the pressing button 65, and the side of the pressing button 65 bulges towards the locking body 63 to form a push block 67. When the pressing button 65 is pushed inward, the pressing push rod 66 maintains its straight sliding posture in the rod groove, while the push block 67 on the side abuts and squeezes the inner section of the locking body 63, causing it to overcome the elastic force of the spring plate 41 and swing to achieve unlocking.

[0033] Furthermore, such as Figure 3 As shown, the bracket body 61 is provided with an axially sliding safety pin 72, the rechargeable battery box 13 is provided with a pin hole 36 that can be adapted to the front end of the safety pin, and the box cover 19 is provided with a push button 73 that is fixedly connected to the side of the safety pin 72 and has a slot 79 for the push button 73 to slide. Pushing the push button 73 can insert or withdraw the safety pin 72 into the pin hole 63, realizing the insertion and locking of the rechargeable battery box 31 or its unlocking, which plays a double role in preventing the rechargeable battery box 31 from sliding sideways. The bracket body 61 is provided with a pin slide groove 76 for the safety pin 72 to slide, and the pin slide groove 76 or the slot 79 is tightly connected to the safety pin 72 or the push button 73 to prevent the safety pin from loosening and falling off.

[0034] The charging battery box 13 is equipped with an independent charging switch 31 that extends out of the box cover 19 or the surface of the battery box. The independent charging switch 31 is connected in series with the charging circuit of the charging battery box. It can cut off the charging circuit to prevent the backup battery in the charging battery box from continuing to charge when the internal lithium battery is low. This achieves the effect of artificially intervening in the charging process, so as to ensure that the power consumption and data transmission and storage functions of the Raspberry Pi are not affected.

[0035] Among them, such as Figure 1 , Figure 4 As shown, each of the placed testing instruments or tools is equipped with an anti-drop connecting rope 38, which is pulled and connected to the side of the corresponding tool slot. Each tool or testing instrument can be pulled and connected by a spring steel wire rope, which serves as the anti-drop connecting rope, and a connecting buckle 39. The connecting buckle 39 can hook onto the ear hole on the tool / testing instrument, avoiding the risk of tools and testing instruments falling when working at height or in confined spaces, eliminating safety hazards to prevent them from falling and being damaged, and forming an anti-loss design, thereby reducing the tool loss rate by more than 30%.

[0036] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
