Description

Technical Field

[0001] This utility model relates to the field of industrial operation and maintenance technology, and more specifically, to an emergency charging interface suitable for track robots. Background Technology

[0002] Currently, the rail-mounted intelligent online inspection device (hereinafter referred to as "inspection robot") is a highly efficient automated inspection device that has been widely used in the status monitoring of cable trays. The existing inspection robot can rely on a preset program to perform infrared thermal imaging and visible light dual-mode periodic inspection of cables within a 300-meter cable tray range. Through non-contact monitoring, it can promptly capture potential faults such as abnormal cable temperature and appearance defects, providing important technical support for the safe operation of equipment.

[0003] However, existing inspection robots still face significant technical bottlenecks in practical applications. The robots rely on built-in batteries for power to perform their inspection tasks. During the execution of pre-set cycle inspection tasks, they are prone to running out of power (i.e., "power outage") due to factors such as insufficient battery power estimation accuracy, abnormal energy consumption fluctuations in complex environments (such as increased power consumption due to high temperature and high humidity), or the addition of temporary inspection tasks. Moreover, the power outage location is often not a pre-set charging point. Once power outage occurs, the robot will directly lose its autonomous movement ability and will not be able to return to the fixed charging station to replenish power.

[0004] In this situation, the maintenance process is forced to stop, requiring manual intervention from maintenance personnel. These personnel must reach the robot's location by working at heights (such as climbing cable trays or using climbing equipment) and manually pull it back to the charging point. However, this approach presents significant safety risks, including falls and mechanical collisions, which seriously threaten the personal safety of maintenance personnel and contradict the high standards of modern industrial safety management. Furthermore, manual pulling requires substantial manpower and time, significantly extending the fault handling cycle, leading to a decrease in the online rate of the inspection system and disruption of task execution continuity. Ultimately, this results in low maintenance efficiency and a substantial increase in both labor and time costs. Utility Model Content

[0005] This utility model aims to provide an emergency charging interface suitable for track robots, in order to solve the problems in the prior art where track-mounted inspection robots cannot return to the charging pile autonomously after being powered off from a non-charging point, requiring maintenance personnel to manually pull them from a height, which poses safety risks, interrupts inspections, low maintenance efficiency, and increased costs.

[0006] The embodiments of this utility model are implemented as follows:

[0007] This utility model embodiment provides an emergency charging interface suitable for a track robot, which includes the robot;

[0008] The robot has a temporary emergency charging port, which is connected in parallel with the battery inside the robot.

[0009] The aforementioned temporary emergency charging port is detachably connected to a connecting cable, which has a power adapter.

[0010] When the robot is stranded on the track due to power failure, maintenance personnel can insert one end of the connecting cable into the temporary emergency charging port. At this time, maintenance personnel can connect the other end of the connecting cable to a power frequency AC power source from a safe location on the ground. The power frequency AC power source is safely and efficiently stepped down, rectified, and stabilized to the robot's operating voltage through the power adapter. The adapted DC power source is then connected to the robot's reserved temporary emergency charging port through the connecting cable to provide temporary emergency power replenishment for the robot's battery. Once the robot has obtained basic power, the operator can remotely and manually control the robot through the robot's control platform to safely and autonomously return to the fixed charging station for a full charge.

[0011] The emergency charging interface for track robots disclosed in this embodiment, equipped with the aforementioned connecting cable containing the power adapter, provides temporary emergency power replenishment when the robot is stranded at any position on the track due to power failure. This ensures that the robot has sufficient power to return to the fixed charging station for recharging. Consequently, this emergency charging interface for track robots has the beneficial effects of completely eliminating safety risks associated with working at heights, improving operation and maintenance efficiency and availability, enhancing system reliability, achieving minimal modification and low-cost deployment, optimizing human resource allocation, extending equipment lifespan, and being easy to operate and implement.

[0012] Optionally, the end of the connecting cable away from the robot is provided with a plug, and the plug is fixed to the end of the connecting cable away from the robot and electrically connected to the connecting cable.

[0013] This configuration of the plug enables quick and stable plugging and unplugging of the connecting cable and the power adapter or temporary emergency charging port, simplifying the emergency power supply process and ensuring that maintenance personnel can easily connect the power source from the ground. This further improves the efficiency and reliability of emergency power supply and avoids unstable power supply caused by loose cable and plug connections during the connection process, ensuring the safety and smoothness of emergency power supply operations.

[0014] Optionally, the plug has a plastic shell, inside which are arranged a first metal conductive plate and a second metal conductive plate that are parallel to each other and spaced apart. One end of the first metal conductive plate and the second metal conductive plate extends to the outside of the plastic shell, and the other end of the first metal conductive plate and the second metal conductive plate is fixed inside the plastic shell and electrically connected to the connecting cable.

[0015] With this configuration, the first and second metal conductive plates are the core components of the plug, responsible for transmitting current, while the plastic shell serves as insulation and protection, ensuring user safety during use.

[0016] Optionally, the end of the connecting cable near the robot has a charging head, which is detachably connected to the temporary emergency charging port.

[0017] This configuration allows the charging head to be electrically connected to the temporary emergency charging port, further securing the cable to the port and effectively preventing it from coming loose.

[0018] Optionally: The above-mentioned charging head and the above-mentioned temporary emergency charging port are both compatible Type-C interfaces.

[0019] This setup leverages the standardized and versatile nature of the Type-C interface to ensure connectivity and compatibility, enabling rapid and accurate connection between the aforementioned charging head and the temporary emergency charging port. Simultaneously, the Type-C interface supports stable and efficient power transmission, guaranteeing the reliability of power supply during emergency power replenishment. Furthermore, the standardized design reduces interface adaptation costs, further enhancing the convenience and practicality of emergency power replenishment operations.

[0020] Optionally: The robot is equipped with a contact charging slider, which is connected in parallel with the battery inside the robot. The temporary emergency charging port is located on the outer wall of the contact charging slider and is electrically connected to the contact charging slider.

[0021] This design achieves stable access to emergency power through a contact structure, ensuring reliable power transmission. Furthermore, integrating the temporary emergency charging port into the outer wall of the contact charging slider optimizes the interface layout, eliminates the need for complex modifications to the robot's core structure, adapts to existing robot forms, further simplifies emergency power replenishment procedures, and enhances the convenience of ground maintenance and the economic efficiency of system upgrades.

[0022] Optionally: The power adapter described above is an AC / DC converter.

[0023] This configuration clearly defines the power adapter as an AC / DC converter, which can efficiently and accurately step down, rectify, and stabilize the industrial frequency AC power (AC220V) to the DC operating voltage required by the robot (such as DC24V / 48V), ensuring the voltage adaptability and stability of emergency power supply. At the same time, the AC / DC converter is a mature and standardized device that is easy to obtain and inexpensive, which meets the characteristics of low-cost deployment of technical solutions, further ensuring the safety, efficiency, and engineering practicality of the emergency power supply process.

[0024] Optionally, the operating voltage of the robot described above is DC24V or DC48V.

[0025] This configuration ensures that the robot's operating voltage is precisely matched to the power adapter's output voltage, guaranteeing the compatibility and safety of power transmission during emergency power replenishment and avoiding the risk of equipment damage due to voltage mismatch. Simultaneously, the standardized DC operating voltage is compatible with conventional commercial power adapters, facilitating maintenance personnel to quickly obtain compatible equipment and ensuring the efficient implementation of emergency power replenishment operations.

[0034] Example

[0035] See Figure 1 , Figure 2 and Figure 3 This embodiment proposes an emergency charging interface suitable for a track robot, including robot 1;

[0036] Robot 1 has a temporary emergency charging port 2, which is connected in parallel with the battery inside Robot 1 (not shown in the figure);

[0037] The temporary emergency charging port 2 is detachably connected to a connecting cable 3, which has a power adapter 4.

[0038] When robot 1 is stuck at any position on the track due to power failure, maintenance personnel can insert one end of the connecting cable 3 into the temporary emergency charging port 2. At this time, maintenance personnel can plug the other end of the connecting cable 3 into an AC power supply at a safe position on the ground. The AC power supply is safely and efficiently stepped down, rectified, and stabilized to the working voltage of robot 1 through the power adapter 4. The adapted DC power supply is then connected to the reserved temporary emergency charging port 2 of robot 1 through the connecting cable 3, which can provide temporary emergency power supplement to the battery of robot 1. After robot 1 obtains basic power, the operator can remotely and manually control robot 1 to safely and autonomously return to the fixed charging pile (not shown in the figure) for a complete charge through the control platform of robot 1 (not shown in the figure).

[0039] This embodiment discloses an emergency charging interface suitable for track robots. Because it is equipped with a connecting cable 3 with a power adapter 4, it can provide temporary emergency power supplementation when the robot 1 is stranded at any position on the track due to power failure. This allows the robot 1 to have enough power to return to the fixed charging pile for charging. As a result, this emergency charging interface suitable for track robots has the beneficial effects of completely eliminating the safety risks of working at heights, improving operation and maintenance efficiency and availability, enhancing system reliability, achieving minimal modification and low-cost deployment, optimizing human resource allocation, extending equipment lifespan, and being easy to operate and implement.

[0040] See Figure 1 , Figure 2 and Figure 3 The end of the connecting cable 3 furthest from the robot 1 is equipped with a plug 5. The plug 5 is fixed to the end of the connecting cable 3 furthest from the robot 1 and electrically connected to the connecting cable 3. The plug 5 enables quick and stable plugging and unplugging of the connecting cable 3 with the power adapter 4 or the temporary emergency charging port 2, simplifying the emergency power supply operation process and ensuring that maintenance personnel can easily complete the power supply connection on the ground. This further improves the efficiency and reliability of emergency power supply and avoids the problem of unstable power supply caused by loose connection between the cable and the plug 5 during the connection process, ensuring the safety and smoothness of the emergency power supply operation.

[0041] The plug 5 has a plastic shell 6. Inside the plastic shell 6, there are first metal conductive plates 7 and second metal conductive plates 8 arranged parallel to each other and spaced apart. One end of the first metal conductive plates 7 and second metal conductive plates 8 extends to the outside of the plastic shell 6, and the other end of the first metal conductive plates 7 and second metal conductive plates 8 is fixed inside the plastic shell 6 and electrically connected to the connecting cable 3. The first metal conductive plates 7 and second metal conductive plates 8 are the core parts of the plug 5, which are responsible for transmitting current, while the plastic shell 6 plays a role in insulation and protection, ensuring the safety of users during use.

[0042] See Figure 1 , Figure 2 and Figure 3 The end of the connecting cable 3 near the robot 1 has a charging head 9. The charging head 9 is detachably connected to the temporary emergency charging port 2. The setting of the charging head 9 facilitates the electrical connection of the connecting cable 3 to the temporary emergency charging port 2, further securing the connecting cable 3 to the temporary emergency charging port 2 and effectively preventing the connecting cable 3 from falling off.

[0043] Both the charging head 9 and the temporary emergency charging port 2 are compatible Type-C interfaces. Utilizing the standardized and universal characteristics of the Type-C interface, connection adaptability and compatibility are ensured, enabling the charging head 9 and the temporary emergency charging port 2 to connect quickly and accurately. At the same time, the Type-C interface supports stable and efficient power transmission, ensuring the reliability of power supply during emergency power replenishment. Furthermore, the standardized design reduces interface adaptation costs, further improving the convenience and engineering practicality of emergency power replenishment operations.

[0044] See Figure 1 , Figure 2 and Figure 3 The robot 1 is equipped with a contact charging slider 10, which is connected in parallel with the battery (not shown in the figure) inside the robot 1. The temporary emergency charging port 2 is located on the outer wall of the contact charging slider 10 and is electrically connected to the contact charging slider 10. On the one hand, the contact structure enables a stable access to emergency power and ensures the reliability of power transmission; on the other hand, integrating the temporary emergency charging port 2 into the outer wall of the contact charging slider 10 optimizes the interface layout, eliminates the need for complex modifications to the core structure of the robot 1, adapts to the existing form of the robot 1, further simplifies the emergency power replenishment operation process, and improves the convenience of ground maintenance and the economy of system modification.

[0045] Power adapter 4 is an AC / DC converter (not shown in the figure). It is clear that power adapter 4 is an AC / DC converter, which can efficiently and accurately step down, rectify and stabilize the industrial frequency AC power (AC220V) to the DC working voltage required by robot 1 (such as DC24V / 48V), ensuring the voltage adaptability and stability of emergency power supply. At the same time, AC / DC converters are mature and standardized devices, which are easy to obtain and inexpensive, in line with the characteristics of low-cost deployment of technical solutions, further ensuring the safety, efficiency and engineering practicality of emergency power replenishment process.

[0046] Robot 1 operates at DC24V or DC48V. The operating voltage of Robot 1 is precisely matched with the output voltage of Power Adapter 4, ensuring the adaptability and safety of power transmission during emergency power replenishment and avoiding the risk of equipment damage due to voltage mismatch. At the same time, the standardized DC operating voltage is compatible with conventional commercial power adapter 4, making it easy for maintenance personnel to quickly obtain compatible equipment and ensuring the efficient implementation of emergency power replenishment operations.

[0047] See Figure 1 , Figure 2 and Figure 3In this embodiment, without altering the original structure, performance parameters, and appearance of the inspection robot 1, only a standardized temporary emergency charging port 2 (Type-C) is added to the robot body. This temporary emergency charging port 2 (Type-C) is connected in parallel with the internal battery. When the robot 1 is stranded at any position on the track due to power failure, maintenance personnel can safely and efficiently step down, rectify, and stabilize the AC power (AC 220V) to the robot 1's operating voltage (such as DC 24V / 48V) from a safe location on the ground using a portable power adapter 4. Subsequently, the adapted DC power supply is connected to the robot 1's reserved temporary emergency charging port 2 via a quick-plug cable 3, providing temporary emergency power to the robot 1's battery. After obtaining basic power, the operator can remotely and manually control the robot 1 through the robot 1's control platform to safely and autonomously return to the fixed charging station for a full charge, ensuring it is ready to perform subsequent inspection tasks.

[0048] See Figure 1 , Figure 2 and Figure 3 In this embodiment, the solution completely avoids the need for maintenance personnel to perform high-altitude traction operations due to power outages of robot 1, fundamentally eliminating the possibility of falls from heights and related safety accidents, significantly improving operational safety, and meeting the highest standards of modern industrial safety management.

[0049] In this embodiment, the operation and maintenance efficiency and availability are significantly improved. The emergency power replenishment operation is simple and quick, and can usually be completed within a few minutes, enabling robot 1 to quickly regain its mobility and return to the charging pile autonomously. This greatly shortens the fault handling time, significantly improves the online rate and task execution efficiency of robot 1, and ensures the continuity and timeliness of inspection work.

[0050] In this embodiment, a reliable "escape" mechanism is provided to effectively address the problem of inaccurate power estimation caused by battery performance degradation, abnormal power consumption in complex environments, and temporary addition of inspection tasks. This significantly improves the fault tolerance and operational reliability of the entire inspection system under complex operating conditions, and enhances the system's robustness and reliability.

[0051] In this embodiment, the technical solution only requires adding a standard temporary emergency charging port 2 to the existing robot 1, without modifying the core hardware, software and appearance structure. The power adapter 4 is a standard commercial device, which is inexpensive and easy to obtain. The implementation cost of this solution is extremely low, and it has extremely high engineering application value and promotion potential, achieving minimal modification and low-cost deployment.

[0052] In this embodiment, the frequency and time of emergency human intervention caused by robot 1 power failure are reduced, freeing up valuable maintenance human resources so that they can focus on higher-value tasks such as data analysis and preventive maintenance, thus optimizing human resource allocation.

[0053] In this embodiment, the robot 1 is prevented from being left in harsh environments (such as high temperature and high humidity cable trays) for a long time due to depletion of power (deep discharge), which helps to protect the health of the battery and the internal components of the robot 1, and may indirectly extend the service life of the equipment.

[0054] In this embodiment, the entire emergency power replenishment process is simple and intuitive, with low skill requirements for on-site operators. Only basic safety and operation training is required, making it easy to quickly popularize and apply in industrial sites.

[0055] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
