When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0053] Figure 1 is a schematic diagram of a transformer oil filling device for a transformer provided by an embodiment of the present application, with reference to Figure 1 , a transformer oil filling device for a transformer, comprising:

[0054] Main mechanical arm 1, auxiliary mechanical arm 2, oil injection mechanical arm 3, bolt tightening mechanical arm 4, oil tank 5, oil pipeline 6 and base 7;

[0055] The main robot arm 1 is arranged on the base 7 and connected to the auxiliary robot arm 2;

[0056] The auxiliary mechanical arm 2 is connected to the oil injection mechanical arm 3 and the bolt tightening mechanical arm 4;

[0057] The oil tank 5 is arranged on the base 7;

[0058] The first end of the oil delivery pipe 6 is connected to the oil tank 5 through the oil pump 8, and the second end thereof passes through the interior of the main mechanical arm 1, the auxiliary mechanical arm 2 and the oil injection mechanical arm 3, and is connected to the oil outlet 10 of the oil injection mechanical arm 3;

[0059] The main mechanical arm 1 is used to drive the auxiliary mechanical arm 2, the oil injection mechanical arm 3 and the bolt tightening mechanical arm 4 to move;

[0060] The auxiliary mechanical arm 2 is used to drive the oil injection mechanical arm 3 and the bolt tightening mechanical arm 4 to move;

[0061] An electric sleeve 9 is provided at the top of the bolt tightening mechanical arm 4;

[0062] The bolt tightening mechanical arm 4 is used to drive the electric sleeve 9 to move;

[0063] The electric sleeve 9 is used to open / close the bolts of the oil tank 5 of the transformer;

[0064] The top of the oil filling mechanical arm 3 is provided with an oil outlet 10;

[0065] The bolt-tightening mechanical arm 4 is used to drive the oil outlet 10 to move;

[0066] The oil outlet 10 is used to connect to the oil filling port of the oil tank 5 of the transformer.

[0067] It should be noted that the main robotic arm 1 in this embodiment is a "vertical arm" which is arranged on the base 7 to play a main supporting role and is mainly used to drive the auxiliary robotic arm 2, the oil injection robotic arm 3 and the bolt tightening robotic arm 4 to perform "rough" displacement adjustment.

[0068] The auxiliary robotic arm 2 is a "cross arm" which is respectively connected to the main robotic arm 1, the oil injection robotic arm 3, and the bolt tightening robotic arm 4, and is used to drive the oil injection robotic arm 3 and the bolt tightening robotic arm 4 to perform further displacement.

[0069] The oiling robot arm 3 and the bolt tightening robot arm 4 are responsible for more "fine" displacement adjustment tasks.

[0070] A socket wrench is generally called a socket. It is composed of multiple sockets with hexagonal holes or twelve-sided holes and equipped with a variety of accessories such as a handle and a connecting rod. It is particularly suitable for tightening bolts or nuts in very narrow positions or deep recesses. The electric socket 9 is an existing maintenance tool that automatically opens / closes the bolt structure by driving the socket to rotate automatically through a motor.

[0071] Preferably, the sleeve diameter of the electric sleeve 9 is adjustable. In this embodiment, a universal electric sleeve 9 can be used to adapt to oil tank 5 bolts of different sizes.

[0072] The oil pump 8 in this embodiment is a bidirectional oil pump 8, which can perform both oil delivery and oil suction tasks.

[0073] This technical solution avoids manual climbing and on-site operations through the linkage of each mechanical arm, and the fully automated operation significantly reduces the safety hazards in high-altitude operations and manual operations. The oil is injected through the oil pipeline 6 extending to the oil injection mechanical arm 3. The oil injection process is accurately controlled by the oil pump 8, which reduces the operation error and improves the stability and efficiency of the overall operation. In addition, there is no need to cut off the power during the operation, thus avoiding the impact of power outages on the power supply to users and ensuring that the transformer is completed in oil replenishment while in operation.

[0074] It should be noted that the transformer oil filling device also includes:

[0075] Operation table;

[0076] An operating handle is provided on the operating table;

[0077] The operating handle is used to issue displacement instructions to the main robotic arm 1, the auxiliary robotic arm 2, the oil injection robotic arm 3 and the bolt tightening robotic arm 4; it also issues clockwise rotation instructions or counterclockwise rotation instructions to the electric sleeve 9; it also issues injection instructions, stop injection instructions and recovery instructions to the oil pump 8.

[0078] It should be noted that the operating handle is operated by the staff to issue instructions.

[0079] In specific practice, the main robot arm 1 drives the auxiliary robot arm 2, the oil injection robot arm 3 and the bolt tightening robot arm 4 to move under the displacement command issued by the operating handle;

[0080] The auxiliary mechanical arm 2 drives the oil injection mechanical arm 3 and the bolt tightening mechanical arm 4 to move under the displacement command issued by the operating handle;

[0081] The bolt tightening mechanical arm 4 drives the electric sleeve 9 to move to the bolt of the oil tank 5 under the displacement instruction issued by the operating handle, and drives the electric sleeve 9 to buckle on the bolt of the oil tank 5;

[0082] The electric sleeve 9 unscrews the bolts of the oil tank 5 under the counterclockwise rotation instruction issued by the operating handle;

[0083] The bolt tightening mechanical arm 4 drives the electric sleeve 9 to move to the side under the displacement instruction issued by the operating handle;

[0084] The oil filling mechanical arm 3 drives the oil outlet 10 to move to the bolt of the oil tank 5 under the displacement instruction issued by the operating handle, and drives the oil outlet 10 to dock with the oil filling port of the oil tank 5 of the transformer;

[0085] The oil pump 8 injects oil under the injection command issued by the operating handle;

[0086] After the oil filling is completed, the oil pump 8 stops filling the oil under the stop injection command issued by the operating handle;

[0087] If too much oil is injected, the oil pump 8 extracts oil from the oil tank 5 of the transformer under the recovery command issued by the operating handle;

[0088] The oil filling robot arm 3 drives the oil outlet 10 to move to the side under the displacement command issued by the operating handle;

[0089] The bolt tightening mechanical arm 4 drives the electric sleeve 9 to move to the bolt of the oil tank 5 under the displacement instruction issued by the operating handle, and drives the electric sleeve 9 to buckle on the bolt of the oil tank 5;

[0090] The electric sleeve 9 tightens the bolts of the oil tank 5 under the clockwise rotation instruction issued by the operating handle to complete the oil filling work.

[0091] It should be noted that the transformer oil filling device also includes:

[0092] Mobile terminals;

[0093] The mobile terminal is wirelessly connected to the operating console;

[0094] The mobile terminal is used to send displacement instructions to the main robotic arm 1, the auxiliary robotic arm 2, the oil injection robotic arm 3 and the bolt tightening robotic arm 4 through the operating console; it also sends clockwise rotation instructions or counterclockwise rotation instructions to the electric sleeve 9; it also sends injection instructions, stop injection instructions and recovery instructions to the oil pump 8.

[0095] Through mobile terminals, operators can remotely monitor and control the device at any location and at any time, avoiding the limitation of having to operate in front of a fixed operating table. This flexible remote control method is particularly suitable for situations where the on-site conditions are complex or the operating environment is inconvenient to directly approach the equipment. Since remote monitoring and command issuance can be achieved, the dependence on high-risk on-site operators is reduced, and safety hazards and related maintenance costs are reduced.

[0096] It should be noted that the console is also equipped with a voice recognition system;

[0097] The voice recognition system is used to recognize the voice commands issued by the user, and issue displacement commands to the main robotic arm 1, the auxiliary robotic arm 2, the oil injection robotic arm 3 and the bolt tightening robotic arm 4 according to the voice commands; it also issues clockwise rotation commands or counterclockwise rotation commands to the electric sleeve 9; it also issues injection commands, stop injection commands and recovery commands to the oil pump 8.

[0098] The voice recognition system enables the operator to give commands by voice without the need for manual operation of the panel, thus achieving precise control of each robot arm, electric sleeve 9 and oil pump 8. This hands-free operation mode is particularly suitable for use in scenarios where the hands are occupied by other tasks or where quick response is required.

[0099] Voice control is usually faster than traditional button or handle input, and can recognize and execute commands in the first time, thus speeding up the operation response. Real-time voice command input can effectively reduce the delay caused by cumbersome operation processes and further improve overall operation efficiency.

[0100] For workers operating at height or in other complex environments, voice control provides a convenient and intuitive way of operation, reducing physical and technical requirements.

[0101] It should be noted that, refer to Figure 2 , the transformer oil filling device also includes:

[0102] Image acquisition device 11;

[0103] The operating table is also equipped with a display screen;

[0104] The image acquisition device 11 is arranged at the connection between the auxiliary mechanical arm 2 and the oil injection mechanical arm 3 and the bolt tightening mechanical arm 4;

[0105] The image acquisition device 11 is communicatively connected with the operation console;

[0106] The image acquisition device 11 is used to acquire image information at the transformer and send the image information to the operation console;

[0107] The operating console displays the image information at the transformer through the display screen.

[0108] By collecting real-time images at the transformer, operators can intuitively understand the status of on-site equipment and connections, ensuring accurate docking of each robot arm. Real-time image feedback helps to promptly detect abnormal conditions, such as loose or leaking joints in the oil tank 5, so that adjustments can be made quickly or safety measures can be taken.

[0109] The image acquisition device 11 makes remote monitoring possible, and operators can grasp the on-site conditions without going to high-risk areas in person, reducing the personal safety risks in on-site operations. By displaying image information in real time on the display screen, operators can find and correct operating errors in the first place, reducing the risk of accidents caused by misoperation.

[0110] Real-time image information provides intuitive data support for the automated control system, helping the robotic arm to achieve precise docking when performing operations such as oiling and bolting.

[0111] It should be noted that a retractable sealing ring is also provided at the top of the oil injection robot arm 3 .

[0112] The sealing ring is installed at the top of the oil filling mechanical arm 3, and can form an effective seal with the oil filling port of the transformer oil tank 5 during the oil filling process to prevent oil leakage at the interface and ensure the integrity of the oil during the transmission process. Effective sealing can not only prevent oil leakage, but also prevent external pollutants such as dust and impurities from entering the oil circuit system, protect the transformer interior and related components from pollution, and thus extend the service life of the equipment.

[0113] Since the robotic arm may have slight displacement or angle changes during operation, the retractable sealing ring can automatically adjust the sealing contact state to ensure that a good sealing effect is maintained at different positions and angles.

[0114] It should be noted that an insulating pad is provided under the base 7 .

[0115] The insulating pad is mainly used to isolate the device base 7 from the ground or other metal structures to prevent accidental contact in a high voltage environment from causing short circuits or electric shock accidents, thereby ensuring the safety of equipment and personnel. Through isolation measures, the insulating pad can reduce the impact of external electromagnetic interference on the internal electronic control part of the system, ensure the stability and accuracy of the control signal, and improve the reliability of the overall system. Around high-voltage equipment such as transformers, the insulating pad can also play a certain buffering role, reducing the impact of mechanical vibration and other external factors on the device base 7, and improving the overall stability and durability of the equipment.

[0116] It should be noted that a liquid level detection sensor is provided at the oil outlet 10;

[0117] The liquid level detection sensor is communicatively connected with the operating console;

[0118] After the oil outlet 10 is connected to the oil filling port of the transformer oil tank 5, the liquid level detection sensor extends into the inside of the transformer oil tank 5 to detect the liquid level data of the transformer oil tank 5 and send the liquid level data of the transformer oil tank 5 to the operating console;

[0119] The operating console displays the liquid level data of the transformer's oil tank 5 through the display screen.

[0120] The liquid level detection sensor can monitor the oil height in the transformer oil tank 5 in real time, ensuring that the staff can understand the oil level status of the oil tank 5 at any time, avoiding excessive or insufficient oil injection, and ensuring the stability of equipment operation. Through real-time liquid level data feedback, the operating console can adjust the oil injection speed and injection amount in time, making the oil replenishment process more accurate and reducing the risk of oil injection deviation caused by human misjudgment.

[0121] During the oil injection process, real-time monitoring of the liquid level can effectively prevent oil overflow. When too much oil is injected, a recovery instruction can be sent to the oil pump 8 to pump oil from the oil tank 5 of the transformer to avoid environmental pollution and safety accidents.

[0122] The communication connection between the liquid level detection sensor and the operating console enables the entire oil filling process to be automatically controlled, reducing the reliance on manual operation and improving the intelligence level of the system. The display screen displays the liquid level data intuitively to the operator, facilitating monitoring and management and improving overall operating efficiency.

[0123] It should be noted that the main robot arm 1 is provided with a storage slot for the auxiliary robot arm 2 , a storage slot for the oil injection robot arm 3 , and a storage slot for the bolt tightening robot arm 4 .

[0124] By providing a storage slot for the auxiliary mechanical arm 2, a storage slot for the oiling mechanical arm 3, and a storage slot for the bolt-tightening mechanical arm 4 on the main mechanical arm 1, the storage slot for the auxiliary mechanical arm 2, the storage slot for the oiling mechanical arm 3, and the bolt-tightening mechanical arm 4 are folded and stored, which not only saves the space occupied by the equipment, but also makes the overall device structure more compact, which helps to improve the installation and layout efficiency of the equipment. The storage slot can place the mechanical arm stably when it is not in operation, effectively isolate external environmental factors (such as dust, vibration, etc.), reduce wear on mechanical parts, and extend the service life of the equipment.
